Description

同时具有两个后出草排出口的四轮草坪割草机Four-wheeled lawn mower with two rear grass discharges 技术领域Technical field
本发明涉及一种用于庭院、公园及道路旁，体育场所修剪草坪的割草机，主要改进目的是加设安全电路保护措施，打造有利于割草，降噪，环保和安全的割草机，特别是一种同时具有两个后出草排出口的四轮草坪割草机。The invention relates to a lawn mower used for gardening, parks and roadsides, and lawn mowers. The main improvement is to add safety circuit protection measures to create a lawn mower that is good for mowing, noise reduction, environmental protection and safety. In particular, a four-wheeled lawn mower that has two rear grass discharges at the same time.
背景技术Background technique
草坪割草机被广泛用于按人们的喜好所选择的方式来割草。由于手推的割草机的机动性能差，且实践中割草时，由于割草机前部较窄的割幅，所以重复割和漏割的现象常有发生，还得去补割，操作者步行割草是很辛苦的。若用坐骑式，也叫骑乘割草机，则坐着比站着感觉有别，但噪音大。若人突离座位，原有3秒保护；但就祘3米/秒，已闯9米还是危险。Lawn mowers are widely used to cut grass in the manner chosen by people's preferences. Due to the poor maneuverability of the hand-picked mower and the mowing in practice, due to the narrow cutting width at the front of the mower, repeated cutting and missing cutting often occur, and it is necessary to repair and operate. It is very hard to walk grass by walking. If you use a mount type, also called a riding mower, sitting feels different than standing, but it is noisy. If the person suddenly leaves the seat, the original 3 seconds protection; but it is 3 meters / sec, it is dangerous to smash 9 meters.
***被广泛作为内燃机特别是小型汽油发动机的消声设备，安装在汽缸盖上排气门口，来降低发动机运行过程的噪音。世界各国对各种行走车辆以及割草机的噪声的极限值都有相关的规定，排气***就是这样一个为减小排气噪音而生的装置。***的性能评价主要有声学性能，空气动力性能及结构性能等指标。内燃机的相当部分属脉动性低频噪声源，多采用抗性或阻抗复和性及微孔板***。常见的内燃机的***尤其是用于小型汽油发动机的***多是三腔式***，消声作用有限；且外部须有较大的防护外罩，但其本身却没有消声作用。再则，其外壳温升较高，发烫，影响安全。若加消声槽当有改善。The muffler is widely used as a muffling device for internal combustion engines, especially small gasoline engines, and is installed on the exhaust valve door of the cylinder head to reduce the noise during engine operation. Countries all over the world have relevant regulations on the noise limits of various walking vehicles and lawn mowers. The exhaust muffler is such a device for reducing exhaust noise. The performance evaluation of the muffler mainly includes acoustic performance, aerodynamic performance and structural performance. A considerable part of the internal combustion engine is a pulsating low-frequency noise source, and a resistance or impedance recombination and a microplate silencer are often used. The muffler of the common internal combustion engine, especially the muffler for the small gasoline engine, is mostly a three-chamber muffler, and the muffling effect is limited; and the outside has a large protective cover, but it does not have a muffling effect itself. In addition, the temperature rise of the outer casing is high, and it is hot, which affects safety. If the anechoic groove is improved.
假脚防护在标准STD.BSI EN 836-ENGL 1997及GB 4706.78-2005/IEC 60335-2-77：2002均有相关要求。多数割草机的割草高度是有多挡可调的，这对操作步行者的脚的安全须按严格控制的安全规定。这通常是做假脚测试的。但假脚测试每天须测试测位较多，复盖产品数量太少。以至于有已经出货的割草机，个别被人测出假脚安规不过，则全部影响割草机定单。改进的想法往往是让割草刀抬高于底盘几毫米。但是由于割刀是细长条的局部弯折过的薄钢板，由于公差，形位公差及装配累计误差的原因，两端的刀尖在大批实际生产中就很难保证不高不低在一个圆周平面上；万一发生的事难避免，但也要确保万台无一出安全问题。一种发明构思如幽灵般地在徘徊：若用厚软的泡沫塑料将割草台及割草机多处外包之，可望收安防及减噪之效，真可谓千虑一得。再多采用安全电路保护措施当更安全。Prosthetic foot protection has requirements in the standard STD.BSI EN 836-ENGL 1997 and GB 4706.78-2005/IEC 60335-2-77:2002. The mowing height of most mowers is adjustable in multiple gears, which is safe for tightly controlled foot safety. This is usually done with a fake foot test. However, the prosthetic foot test has to test more positions every day, and the number of covered products is too small. As a result, there are already lawn mowers that have already been shipped. Individuals have been tested for fake foot safety, but all affect the mower order. The idea of improvement is often to lift the mowing knife a few millimeters above the chassis. However, since the cutter is a partially bent thin steel plate of a slender strip, due to tolerances, geometrical tolerances and cumulative assembly errors, it is difficult to ensure that the cutter tips at both ends are not high or low in a large number of actual production. On the plane; in case something happens, it is difficult to avoid, but we must also ensure that there is no safety problem. An inventive concept, such as ghostly in the hustle and bustle: If you use a thick soft foam to outsource the mower and mower, you can expect security and noise reduction effects. More safety circuit protection measures are used to be safer.
为了避免两把刀的相邻的间隙所造成的漏割现象，原有的坐骑式割草机的两把刀，通常是一前一后。请参看图23，这是原有的坐骑式割草机的一前一后两把刀的传动示意图，图中，23a是第一刀的轴上的皮带轮，23b是第二刀的轴上的皮带轮，11是发动机的皮带轮。两刀的长条形是互垂且反向转的，以便互不干涉；用的是双面V形带，还用了三个张紧轮，更主要的缺点是因刀有前后，使割盘前后加大，致使前后轮距加大，整机加长，车回转半径变大，纵向潜势稳定系数变差，成本加多，而这些都是所不希望的。另一种原有的坐骑式割草机的两把刀，虽不是一前一后的，参看图24，因两刀是反向转的，以便互不干涉，用的是双面同步带，还得用两个同步张紧轮，这使得成本加大。如果无张紧轮及用普通皮带 驱动，是能降低成本；但不用张紧，皮带就太松而不好用，除非主次带轮间距进一步大幅缩短；双割草刀间必不可免地要有重割率以防漏割，多用双割草刀间距小于刀直径；这样就要求双割草刀反向旋转，且要求双割草刀交错开有一定相位，这就要求双割草刀相互转速恒定，就要用同步齿形带；但问题是不但张紧结构复杂，同步齿形带及轮成本提高，更不希望的是因双割草刀反向旋转而不能同时设有宽幅的后排草和侧排草，市场上客观上需要一种同时具有两个后出草排出口的四轮草坪割草机面世，以求不堵草使草入集草袋。In order to avoid the leakage caused by the adjacent gaps of the two knives, the two knives of the original mount mower are usually in tandem. Please refer to Figure 23, which is a transmission diagram of the front and rear two knives of the original mount mower. In the figure, 23a is the pulley on the shaft of the first knives, and 23b is the shaft on the second knives. The pulley, 11 is the pulley of the engine. The long strips of the two knives are mutually perpendicular and reversed so as not to interfere with each other; the double-sided V-belt is used, and three tensioning wheels are used. The main disadvantage is that the knives have front and rear The front and rear of the disc are enlarged, resulting in an increase in the front and rear track lengths, the lengthening of the whole machine, the turning radius of the vehicle becoming larger, the stability coefficient of the longitudinal potential becoming worse, and the cost increasing, which are undesirable. The other two knives of the original mount mower, although not in tandem, refer to Figure 24, because the two knives are reversed so that they do not interfere with each other, using a double-sided timing belt. It is also necessary to use two synchronous tensioning wheels, which increases the cost. If there is no tensioner and ordinary belt Drive, can reduce costs; but without tension, the belt is too loose and not easy to use, unless the primary and secondary pulley spacing is further shortened significantly; the double mowing knife must inevitably have a heavy cutting rate to prevent leakage. The spacing between the multi-purpose mowing blades is smaller than the diameter of the knife; thus, the double mowing blades are required to rotate in the opposite direction, and the double mowing blades are required to be staggered to have a certain phase, which requires the double mowing blades to have a constant rotational speed, and the synchronous tooth shape is used. The problem is that not only the tensioning structure is complicated, but also the cost of the synchronous toothed belt and the wheel is increased. What is more undesirable is that the double lawn mower cannot be simultaneously provided with a wide rear grass and side grass due to the reverse rotation of the double mowing knife. Objectively, there is a need for a four-wheeled lawn mower that has two rear grass discharges at the same time, in order to prevent grass from entering the grass bag.
发明内容Summary of the invention
本发明涉及一种用于庭院、公园及道路旁，体育场所修剪草坪的割草机，主要改进目的不但是加设安全电路保护措施，使综合效果既有利于割草，操作舒适，无级变速，又有利于降噪，环保和安全，而且是为了能降低成本；但不用张紧，皮带就太松而不好用，除非主次带轮间距进一步大幅缩短；双割草刀间必不可免地要有重割率以防漏割，多用双割草刀间距小于刀直径；这样就要求双割草刀反向旋转，且要求双割草刀交错开有一定相位，这就要求双割草刀相互转速恒定，就要用同步齿形带；但问题是不但张紧结构复杂，同步齿形带及轮成本提高，更不希望的是因双割草刀反向旋转而不能同时设有宽幅的后排草和侧排草，市场上客观上需要一种同时具有两个后出草排出口的四轮草坪割草机面世，以求不堵草。The invention relates to a lawn mower used for gardens, parks and roads, and lawn mowers. The main purpose of improvement is not only to install safety circuit protection measures, but also to make the comprehensive effect beneficial to mowing, comfortable operation and stepless speed change. It is also conducive to noise reduction, environmental protection and safety, but also to reduce costs; but without tension, the belt is too loose and not easy to use, unless the primary and secondary pulley spacing is further shortened; double mowing blades are inevitable The ground should have a heavy cutting rate to prevent leakage cutting. The distance between the double cutting blades is smaller than the diameter of the knife; thus, the double mowing blades are required to rotate in the opposite direction, and the double mowing blades are required to be staggered to have a certain phase, which requires double mowing. When the knives rotate at a constant speed, it is necessary to use a synchronous toothed belt; but the problem is that not only the tensioning structure is complicated, but also the cost of the synchronous toothed belt and the wheel is increased. What is more undesirable is that the double mowing blades cannot be simultaneously widened due to the reverse rotation. The rear grass and the side row of grass in the market objectively require a four-wheeled lawn mower with two rear grass discharges at the same time, in order not to block the grass.
本发明解决其技术问题所采取的技术方案是再以有安全电路保护措施的割草机及安全保护有降噪的割草机的先驱而不断改进和完善的无张紧轮普通皮带驱斜置同向双割草刀双排草宽幅割草机为参照而创新的同时具有两个后出草排出口的四轮草坪割草机以求不堵草。The technical solution adopted by the present invention to solve the technical problem is to continuously improve and perfect the untensioned wheel ordinary belt drive obliquely by the lawn mower with safety circuit protection measures and the pioneer of the lawn mower with safety protection noise reduction. In the same direction, the double-grass double-row grass wide lawn mower is innovative and has two four-wheeled lawn mowers with a rear discharge outlet for the purpose of not blocking grass.
有安全电路保护措施的骑乘割草机，是加设安全电路保护措施的有降噪措施及液压无级变速的骑乘割草机，包括安全电路保护措施，及连接两个前轮的可转向的前桥，连接两个后轮的带液压无级变速的可驱动后桥，四轮上方的带双保险杠的车架，车架下方的有降噪的割草装置，车架上方靠前的带消声槽的发动机和有降噪的车头罩(1)及消声的空气过滤网(4)，车架上方中部偏后的有降噪的车座，以及车后方有降噪的收草箱，还有坐骑操作者个人防护附件包括耳塞，防声棉，耳罩和防声头盔；其特征是：在有降噪的车头罩1及消声的空气过滤网4的相连处，设有两个车灯3，既要注意粘缝不要太漏音，更要注意温升，若用灯是LED发光管，则温升没问题；说到灯，就要说到电路；为了安全，在骑乘割草机上就得加装安全电路保护措施，所述的安全电路，主要由单板机及仪表插件(C4)，引擎插件(C1)，扩展插件(C5)，点火开关(C2)，蓄电池(B1)，直流继电器(C3)，动力输出PTO开关(C6)，电磁离合器(C7)，启动器(ST)，挂箱蜂鸣器(U1)，满草蜂鸣器(U2)，第一保险(F1)，第二保险(F2)，前照灯开关(S0)，左前照灯(L1)，右前照灯(L2)，驻车开关(S1)，N档开关(S2)，座位开关(S3)，挂集草箱开关(S4)，满草报警开关(S5)所组成，所述的左前照灯(L1)和右前照灯(L2)，各由多个，例如4个发光二极管串联而成，也可加电阻；或各由多个发光二极管串并联，例如4串4并即各由16管组合而成，而且，最好多管沿弧形扇面排列，以利扩大视角范围；所述的座位开关(S3)，现作了新构思的非常规的设计；因为原有的座位开关，虽然座位未被坐下时座位开关是断开的，当驾驶员坐下后才能开动；若驾驶员离开座 位后，有3-5秒的单板机延迟熄火控制，这听起来好象很安全了，其实不然；原有的座位开关是个长期的很难解决的老大难问题，因当实际作业时，草地是颠簸的，屁股是抖动的，座椅是上下的，座位开关是忽通忽断的，特别是当驾驶员不慎跌落时，有3-5秒的单机延迟熄火控制，要等3-5秒后才熄火；割草机行走速度在3.6至15公里/小时，既使取最慢速每秒一米，也要冲出3-5米，或十几米远才能停车，不难想象这对坠落的手脚或障碍物意味着什么；虽然在通常情况下已***截面相配的碳刷(S3-2)的端面亦应是平面的，以便相配处导电接触良好；注意，所述的长滑杆(S3-1)的中部是导体，例如是铜的，而两端是绝缘体，例如是塑料的，且所述的导体上设有柔和的导线与开关(S3)的一个接线端子连接；而所述的碳刷上亦设有柔和的导线与开关(S3)的另一个接线端子连接；所述的碳刷后设有复位弹簧；因所述的长滑杆(S3-1)与座位(9)随动，而可一并由装在座位9下的座位弹簧(9-2)来复位，当然亦可在所述的长滑杆的下端设辅助复位弹簧；故当人坐在座位上时，所述的长滑杆(S3-1)的长杆形导体***和拉出的幅度尽管很大，然而长杆形导体与碳刷却总是接触良好的；而当人离开座位时，所述的长滑杆(S3-1)的长杆形导体在座位弹簧(9-2)的全力作用下，马上就上拉，其幅度大于人坐的晃悠的幅度区域时，就使长杆形导体与碳刷断开，仅是长滑杆的绝缘部分与碳刷接触；所述的长滑杆(S3-1)的长杆形导体和长滑杆的下部的绝缘部分的接合处不能有台阶或高低不平，成型后最好作机加工，如车铣或其它加工方法，以利于滑动而不卡；在熄火状态时，点火开关(C2)的M，G接通，主电路被短路，单板机及仪表插件(C4)和引擎插件(C1)的2号黑线短接，导致汽油发动机熄火；在运行状态时，点火开关(C2)的B，L接通，主电路被接通，单板机及仪表插件(C4)通过5号蓝线通电，引擎插件(C1)的第一端输入高电平，使装在发动机的化油器的电磁阀动作，而使油门开关打开；油门档位处于N档位置时，N档开关(S2)断开，仪表显示灯亮；驻车状态时，驻车开关(S1)关闭，仪表上显示灯N亮；座位未被坐下时，座位开关(S3)断开，仪表上显示灯P亮；若在集草箱未挂的状态下，挂集草箱开关(S4)断开，集草箱警示灯亮，同时蜂鸣器(U1)发出连续的警报声；当在蓄电池(B1)电压不足的状态下，接通主电路的电压过低，蓄电池指示灯亮；当闭合前照灯开关(S0)时，前照灯亮；在启动状态时，点火开关(C2)的B，L，S接通，主电路被接通，运行的功能均能实现；S端的暗红线接入单板机及仪表插件(C4)的4号线端，并通过单板机控制接收到4号线端的高电平信号，控制3号线端 的输出高电平信号，接入直流继电器，使直流继电器(C3)导通，电源通过直流继电器流入到启动器(ST)，所述的启动器(ST)是设在发动机上的直流电动机，其通过传动机构拖动发动机主轴起转，而使汽油发动机启动；启动控制，是由单板机来判别是否符合以下5种启动状况：1.油门处于N档状态，N档开关断开，导致7号线端未能通过N档开关形成回路；2.动力输出PTO开关(C6)左端合，因PTO开关总是一组开关常开，一组开关常闭，图上位置为开关(C6)左端合，右端断的状态，此时割刀分离不工作，11号线端蓝线通过PTO开关(C6)左端割刀开关PTO输出形成回路；3.座位被坐下，座位开关被闭合，8号线端橙线通过座位开关输出形成回路；4.车辆被驻车时，驻车开关S1闭合，6号线端紫线通过驻车开关输出而形成回路；5.集草箱或后盖板挂上时，挂集草箱开关(S4)压下，9号线端暗红线通过挂集草箱开关形成回路；所以，当点火开关处于启动状态时，4号线端暗红线输入高电平信号到仪表插件，就由单板机来判别是否符合以上5个信号要求，如果符合，则会在3号线端紫线输出高电平，使直流继电器(C3)导通，起动器工作；熄火控制：车辆在运行后的熄火控制；有5种信号或5种熄火信号；信号1.驻车开关，未驻车状态时，驻车开关OFF断开，6号紫线未能形成回路输出，驻车状态反之；信号2.N档开关，油门档位未在N档位置时，N档开关ON闭合，7号线端灰线形成回路输出，在N档位置反之；信号3.座位开关，座位未被坐下时，座位开关(S3)断开，8号线端橙线未能形成回路输出，座位被坐下反之；信号4.挂集草箱开关，若在集草箱未挂的状态下，挂集草箱开关(S4)断开，集草箱警示灯亮，同时蜂鸣器U1发出连续的警报声，9号暗红线端未能形成回路输出，集草箱或后盖板挂上时反之；信号5.动力输出PTO开关(C6)，因为PTO开关总是一组开关常开，一组开关常闭，图上位置为开关(C6)左端合的状态，此时割刀分离不工作，11号线端蓝线通过PTO开关(C6)左端割刀开关PTO输出形成回路；而当PTO开关(C6)左端不合，右端合时，电磁离合器(C7)吸合，割刀结合，11号线端蓝线通过PTO开关(C6)左端割刀开关PTO输出未能形成回路，此时仪表上割刀工作显示灯亮；5种熄火信号是：1.上述5个信号中，PTO启动时，割刀结合，座位未被坐下，则发动机延迟3-5秒熄火；2.上述5个信号中，集草箱或后盖板未挂好，集草箱警示灯亮，同时蜂鸣器U1发出连续的警报声，发动机立即熄火；3.上述5个信号中，车辆被驻车时，驻车开关(S1)闭合，PTO开关(C6)左端不合，右端合时，电磁离合器(C7)吸合，割刀结合，则单板机令发动机立即熄火；4.上述5个信号中，未处于N档位置时，座位未被坐下，则发动机延迟3-5秒熄火；5.上述5个信号中，油门档位处在N档位置时，未驻车状态下，座位未被坐下，则发动机延迟3-5秒熄火；当车辆在满足上述一种或多种熄火信号时，通过单板机对上述信号的判别，再通过继电器控制，使2号线端的黑线短接，即使引擎插件C1的熄火线输出接地，导致汽油发动机熄火，延迟时间是通过单板机延时子程序来实现的。下面说几个控制。先说驻车控制，车辆被驻车时，驻车开关(S1)闭合，档位处于N档位置，座位未被坐下，PTO开关左端合，右端不合，电磁离合器(C7)不吸合，割刀不结合，集草箱和后盖板被挂上，发动机仍处于怠速状态。再说行驶控制，未驻车状态下，或在有时错误操作而致的驻车状态下，档位未处于N挡位置，座位被坐下，PTO开关左端合，右端不合，电磁离合器(C7)不吸合，割刀不结合，集草箱和后盖板被挂上， 发动机不熄火；接着说刹车控制，在运行状态下，踩下刹车，未驻车状态下，档位处于N挡位置，座位被坐下，PTO开关左端合，右端不合，电磁离合器(C7)不吸合，割刀不结合，集草箱和后盖板被挂上，发动机仍然处于工作状态；下面说割草控制，在未驻车状态下，档位未处于N挡位置，或档位处于N档原地割草，座位被坐下，PTO开关左端不合，右端合，电磁离合器(C7)吸合，割刀结合，集草箱和后盖板被挂上，发动机仍然处于工作状态；最后叙述一下满草报警***，当集草箱草满时，满草报警开关(S5)被压下，10号线端褐色线通过满草箱报警开关(S5)形成回路，此时蜂鸣器(U2)发出警报声，获得所期望的安全效果。A riding mower with safety circuit protection measures is a noise-reduction measure with added safety circuit protection measures and a hydraulic stepless speed change riding mower, including safety circuit protection measures, and connection of two front wheels. Steering front axle, two rear-wheel driveable rear axles with hydraulic stepless speed change, four-wheeled double-bumper frame, noise-reducing mowing device under the frame, above the frame The front engine with anechoic slot and the noise-reducing front cover (1) and the muffling air filter (4), the noise-reducing seat behind the middle of the frame, and the noise reduction behind the car The straw box and the personal protective accessories of the mount operator include an earplug, an anti-sound cotton, an earmuff and an anti-sound helmet; and the feature is: at the junction of the noise reduction hood 1 and the muffling air filter 4, There are two lights 3, not only the sticky seam should not be too leaky, but also pay attention to the temperature rise. If the lamp is an LED tube, the temperature rise is no problem; when it comes to the lamp, it is necessary to say the circuit; Safety circuit protection measures must be added to the riding mower. The safety circuit is mainly Board and instrument plug-in (C4), engine plug-in (C1), expansion plug-in (C5), ignition switch (C2), battery (B1), DC relay (C3), PTO switch (C6), electromagnetic clutch (C7) ), starter (ST), hanging box buzzer (U1), grass buzzer (U2), first insurance (F1), second insurance (F2), headlight switch (S0), left front Light (L1), right headlight (L2), parking switch (S1), N-speed switch (S2), seat switch (S3), hanging grass box switch (S4), grass-filled alarm switch (S5) The left headlight (L1) and the right headlight (L2) are each formed by a plurality of, for example, four light emitting diodes connected in series, or may be added with a resistor; or each of the plurality of light emitting diodes may be connected in series, for example, 4 strings. 4, that is, each of 16 tubes are combined, and it is preferable that the plurality of tubes are arranged along the curved sectors to expand the viewing angle range; the seat switch (S3) is now a new concept of unconventional design; The original seat switch, although the seat switch is disconnected when the seat is not seated, can only be activated when the driver sits down; if the driver leaves the seat After the position, there is a 3-5 second single-board machine with delayed flameout control, which sounds like it is safe, but it is not; the original seat switch is a long-standing problem that is difficult to solve, because when it is actually working, The grass is bumpy, the buttocks are shaking, the seats are up and down, the seat switch is suddenly broken, especially when the driver accidentally falls, there is a 3-5 second single-stage delayed flameout control, to wait 3- After 5 seconds, the flame is turned off; the mower travels at a speed of 3.6 to 15 km/h. Even if the slowest speed is one meter per second, it must be 3-5 meters or more than ten meters to stop. It is not difficult to imagine this. What it means to fall hands, feet or obstacles; although it is customary to use a single-machine delayed flameout control with 3-5 seconds, in order to eliminate unsafe hazards, a new concept of unconventional design is required. The seat switch must be safe when the seat switch is not too expensive. When the seat is shaken up and down a lot, the seat switch can not be turned off and on, and when it is really disconnected, it must be cut off within 0.1 second. Open; the seat switch provided by the present invention is solved An old problem; referring to Fig. 28, the seat switch (S3) is mainly composed of a long slide bar (S3-1) provided under the seat (9), and a guide rail provided on the long slide bar.

具体实施方式detailed description
所采取的技术方案是以有安全电路保护措施的割草机及安全保护有降噪的割草机为先驱而不断改进和完善的无张紧轮普通皮带驱斜置同向双割草刀双排草宽幅割草机。The technical solution adopted is based on the lawn mower with safety circuit protection measures and the lawn mower with safety protection and noise reduction. The untensioned wheel is usually improved and perfected. Row grass wide lawn mower.
有安全电路保护措施的骑乘割草机，是既有安保电路又有降噪措施及液压无级变速的 骑乘割草机，除安全电路保护措施外，还包括连接两个前轮的可转向的前桥，连接两个后轮的带液压无级变速的可驱动后桥，四轮上方的带双保险杠的车架，车架下方的有降噪的割草装置，车架上方靠前的带消声槽的发动机和有降噪的车头罩1以及消声的空气过滤网4，车架上方中部偏后的有降噪的车座，以及车后方有降噪的收草箱10和车身10c；以及为坐骑操作者的个人防护而配有的耳塞，防声棉，耳罩和防声头盔诸附件，以提高综合品质。所述的骑乘割草机所包括的连接两个前轮的可转向的前桥，包含在两个前轮6之间通过公知的平行四边形转向机构，即通过一连杆连接的左弯轴和右弯轴，所述左弯轴上端通过一节臂固定在控制杆的一端，控制杆的另一端则固连在带有方向盘8的齿轮和有锥度的齿盘8a上，故便于操纵方向。如图9，图10，图13以及图15所示，所述的齿盘8a的特征是：其齿盘8a的齿是内齿，特别是内齿面有锥度，而原来没有；如果是外齿，因外齿对外齿易有让位现象，则没有内齿轮和方向盘的外齿轮配得这样默契；又因为现改进为有锥度或倒角，就更易与斜的齿相配。其锥度小于30度，最好是18度；因为齿盘8a是水平安装，以连接平行四边形转向机构，而方向盘8的齿轮的轴线与铅垂线是有角度的，一般是18度，故便于操作；要按实况调间隙，并加脂润滑。The riding mower with safety circuit protection measures is both a security circuit and noise reduction measures and hydraulic stepless speed change. The riding mower, in addition to the safety circuit protection measures, also includes a steerable front axle connecting the two front wheels, a driveable rear axle with hydraulic stepless speed change connecting the two rear wheels, and a double belt above the four wheels The frame of the bumper, the lawn mower with noise reduction under the frame, the engine with the anechoic groove on the front of the frame, the hood cover with noise reduction 1 and the air filter 4 for sound elimination, above the frame a noise-reducing seat in the middle of the center, and a straw-removing bin 10 and body 10c at the rear of the car; and earplugs, soundproof cotton, earmuffs and anti-sound helmet for personal protection of the rider Attachments to improve overall quality. The steerable front axle connected to the two front wheels included in the riding lawn mower includes a known parallelogram steering mechanism between the two front wheels 6, that is, a left curved shaft connected by a connecting rod And the right curved shaft, the upper end of the left curved shaft is fixed to one end of the control rod by one arm, and the other end of the control rod is fixed to the gear with the steering wheel 8 and the tapered toothed disc 8a, so that the steering direction is convenient . As shown in FIG. 9, FIG. 10, FIG. 13 and FIG. 15, the toothed disc 8a is characterized in that the teeth of the toothed disc 8a are internal teeth, in particular, the inner tooth surface has a taper, but the original is not; if it is outside Tooth, because the external teeth are easy to give way to the external teeth, there is no such thing as the internal gear of the internal gear and the steering wheel; and because it is now tapered or chamfered, it is easier to match the oblique teeth. The taper is less than 30 degrees, preferably 18 degrees; because the toothed disc 8a is horizontally mounted to connect the parallelogram steering mechanism, and the axis of the gear of the steering wheel 8 is angled with the plumb line, generally 18 degrees, so it is convenient Operation; adjust the gap according to the actual situation, and grease lubrication.
所述的有降噪措施及液压无级变速的骑乘割草机所包括的连接两个后轮6b的带液压无级变速的可驱动后桥24，如图20所示，这是拆去多个连接螺丝及一半后桥，而剩一半后桥且露出内部的两个柱塞泵和液控阀组及多个齿轮的正视示意图，所述的后桥包含设在两个后车轮之间的两个半轴，在两个半轴之间设有差速器，由此差速器向上依次连接第二柱塞泵24c和液控阀组的无级变速机构和制动装置，再经液控阀组连接第一柱塞泵24b的离合机构，再经由第一柱塞泵的转动轴上的皮带轮的皮带22，传递发动机主轴11的动力，其特征是：所述差速器包括一对半轴齿轮，半轴齿轮之间的行星轮总成，行星轮总成的星轮24h最好用2个星轮，且每个星轮齿数为12；行星轮总成架设在一个较大的大齿轮24g上，最好其齿数为53；所述的大齿轮24g与中间小齿轮24f啮合，最好其齿数为11；所述的中间小齿轮24f与中间齿轮24e同轴且固联，最好其齿数为48；所述的中间齿轮24e与第二柱塞泵的变速齿轮24d啮合，最好其齿数为13，所以形成了减速器而增力，及形成了差速器而使转弯灵活。所述的第二柱塞泵的柱塞最好用5个，比第一柱塞泵的柱塞多，每一个柱塞的缸径就较大，故作为油马达而言，输出力矩就较大。因为第二柱塞泵的变速齿轮的同轴上设有制动装置的制动盘，在制动盘的近旁的后桥24上设有摩擦片，制动拉杆及弹簧而组成制动装置，故便于与车架中部的脚刹车器12和手刹车器13相连；本车的脚刹车器12和手刹车器13实际上是同一套机构。在第二柱塞泵和第一柱塞泵之间的液控阀组上，设有变档杆，一方面调控液控阀组上的进出油口，另一方面改变第一柱塞泵的柱塞顶部斜面的角度来改变输出转速，故便于与车架中部的前进档14和后退档14b相连，以组成无级变速机构；当空档时，第一柱塞泵的柱塞顶部斜面的角度为零，空转而无输出，第一柱塞泵起到了离合器的作用；前进档14和后退档14b相连，操纵无级变速机构；当踩下前进档14时，在第二柱塞泵和第一柱塞泵之间的液控阀组上的变档杆，调控液控阀组上的进油口；踩得深，使进油口大则车速快；踩得浅，进油口小则车速慢，故实现无级变档；当压下后退档14b时，在第二柱塞泵和第一柱塞泵之间的液控阀组上的变档杆反向， 使调控液控阀组上的进出油口反向，使第二柱塞泵反转，驱动后面的减速器和差速器反转，使之倒车。因第二柱塞泵在这里实际上是当油马达用的，其带动变速齿轮24d与一系列齿轮啮合，从而驱动两个半轴和后轮6b。在第二柱塞泵和第一柱塞泵之间的液控阀组上，还设有驻车杆，调控液控阀组的内油口，当扳到驻车位时，驻车杆的内部的D形杆阻碍内油口。在所述的可驱动后桥24内部设有进油阀24k以连通外油盒，故方便润滑；在所述的可驱动后桥24内还设有永久磁铁24j，或用马蹄形磁铁，因有磁廻流而效果好，或设在多处，故利于吸住各钢铁件经长久磨损后而混入油中的铁屑。The noise reduction measure and the hydraulic stepless speed change riding lawn mower include a hydraulically extendable shiftable rear axle 24 connecting the two rear wheels 6b, as shown in FIG. 20, which is removed. a front view of a plurality of connecting screws and half of the rear axle, leaving half of the rear axle and exposing the internal two piston pumps and the hydraulic control valve block and the plurality of gears, the rear axle being disposed between the two rear wheels The two half shafts are provided with a differential between the two half shafts, whereby the differential connects the second plunger pump 24c and the continuously variable shifting mechanism and the brake device of the hydraulic control valve group in turn, and then The hydraulic control valve group is connected to the clutch mechanism of the first plunger pump 24b, and transmits the power of the engine main shaft 11 via the belt 22 of the pulley on the rotating shaft of the first plunger pump, wherein the differential includes a differential For the half shaft gear, the planetary gear assembly between the half shaft gears, the star wheel 24h of the planetary wheel assembly preferably uses two star wheels, and the number of teeth of each star wheel is 12; the planetary wheel assembly is erected in a larger The large gear 24g preferably has a number of teeth 53; the large gear 24g is meshed with the intermediate pinion 24f, preferably the number of teeth 11; the intermediate pinion 24f is coaxial and fixed to the intermediate gear 24e, preferably having a number of teeth of 48; the intermediate gear 24e is meshed with the shifting gear 24d of the second plunger pump, preferably having a number of teeth of 13 Therefore, the speed reducer is formed to increase the force, and the differential is formed to make the turning flexible. Preferably, the plunger of the second plunger pump is five, which is larger than the plunger of the first plunger pump, and the diameter of each plunger is larger, so the output torque is larger as the oil motor. . Because the brake gear of the second piston pump is coaxially provided with the brake disc of the brake device, the rear axle 24 near the brake disc is provided with a friction plate, a brake lever and a spring to form a brake device. Therefore, it is convenient to connect with the foot brake 12 and the hand brake 13 in the middle of the frame; the foot brake 12 and the hand brake 13 of the vehicle are actually the same mechanism. A shift lever is arranged on the hydraulic control valve group between the second plunger pump and the first plunger pump, on one hand, the inlet and outlet ports on the liquid control valve group are adjusted, and on the other hand, the first plunger pump is changed. The angle of the top slope of the plunger changes the output speed, so it is convenient to connect with the forward gear 14 and the reverse gear 14b in the middle of the frame to form a continuously variable shifting mechanism; when in neutral, the top of the plunger of the first plunger pump is inclined The angle is zero, idle without output, the first plunger pump acts as a clutch; the forward gear 14 and the reverse gear 14b are connected to operate the continuously variable shifting mechanism; when the forward gear 14 is depressed, the second plunger pump and The shift lever on the liquid control valve group between the first plunger pump regulates the oil inlet on the liquid control valve group; the deep stepping makes the speed of the oil inlet large; the step is shallow, the oil inlet is small If the vehicle speed is slow, the stepless shifting is realized; when the reverse gear 14b is depressed, the shift lever on the hydraulic control valve group between the second plunger pump and the first plunger pump is reversed, The inlet and outlet ports on the regulating liquid control valve group are reversed, the second plunger pump is reversed, and the rear reducer and the differential are driven to reverse, so that the vehicle is reversed. Since the second plunger pump is actually used for the oil motor here, it drives the shift gear 24d to mesh with a series of gears, thereby driving the two half shafts and the rear wheel 6b. On the hydraulic control valve group between the second plunger pump and the first plunger pump, a parking rod is further arranged to regulate the internal oil port of the hydraulic control valve group, and when the parking position is pulled, the interior of the parking rod is The D-bar hinders the internal port. An oil inlet valve 24k is disposed inside the driveable rear axle 24 to communicate with the outer oil tank, so that lubrication is facilitated; a permanent magnet 24j or a horseshoe magnet is also provided in the driveable rear axle 24, Magnetic turbulence has a good effect, or is located in multiple places, so it is good for sucking iron scraps that are mixed into the oil after long-wearing of the steel parts.
又因为有降噪措施及液压无级变速的骑乘割草机所包括的四轮上方的带双保险杠的车架，如图2所示，在车的前方设有保险杠，其特征是：所述的保险杠是双杠，或三个，或更多，且每杠是两头弯，中间直的圆管或方管，而且至少有两处支架支撑；双杠比单的应更保险；作为改进，所述的支架不是钢性的，而是弹性的，例如用弹簧，或弹性材料如橡胶或聚氨脂，故更利于缓冲。And because of the noise reduction measures and the hydraulic stepless speed change riding lawn mower, the frame with double bumper above the four wheels, as shown in Figure 2, has a bumper in front of the car, which is characterized by The bumper is a parallel bar, or three or more, and each bar is a two-bend, straight pipe or square tube in the middle, and at least two brackets are supported; the parallel bars are more secure than the single one; In addition, the bracket is not steel, but elastic, such as a spring, or an elastic material such as rubber or polyurethane, which is more conducive to cushioning.
又因为有降噪措施及液压无级变速的骑乘割草机所包括的车架下方的有降噪的割草装置，包括高度调节部分和割草部分；参看图5，高度调节部分，按平行四边形原理，由设在车架上的前定轴(18a)和后定轴18c，及设在割盘18上的前动轴18b和后动轴18d及与之相连动的杆件，以及供拉动用的钢丝绳18h，扇形齿轮18g，棘爪18f和调高手柄15所组成，其特征是：所述的设在车架上的前定轴18a和后定轴18c，及设在割盘上的前动轴18b和后动轴18d是平行四边形的四个顶点，其相对应边是两两平行且相等的，所以，无论怎样通过调高手柄15来拉动钢丝绳18h，并通过扇形齿轮18g，棘爪18f来给几个调高档位，车架上的前定轴18a和后定轴18c的连线，总是与割盘上的前动轴18b和后动轴18d是平行的，从而在根本上保证了割盘的上下平移而正常工作；但实用时还是要调好钢丝绳18h的长短，以及扇形齿轮18g和棘爪18f的调配。整个割盘虽是近乎在各档位是平行的，但还是前后有移动，是以动力皮带21连着的发动机主轴11为圆心，经皮带21传到第一刀座的距离纵向投影为半径而移动的，且皮带21也有高度差，是斜的，幸好还能用。从图6可看出，因为调高档位的所述的扇形齿轮18g有多齿，现优选10齿，有10档，例如能在10-100mm割高来调；或按常用的25-85mm，分几个档最好按客户要求。参看图10，割草部分的动力从发动机主轴11，经皮带21传到第一刀座，再经同步带23传到第二刀座，故便于带动割草刀20工作；作为改进，参看图14和图16，所述的割草刀20上设有两个或多个风翅，为了切断缠草，在所述的风翅上设有多个刃口20a，所述的刃口的两面的夹角不是直角，最好是小于60度的锐角；进一步作为改进，所述的割草刀20上设有多个六方孔，或更进一步改进，所述的割草刀20上设有多个如蜂巢或如尖劈7b的凸凹，故利于改变流经刀的高速微气流的声频即降噪。And because there are noise reduction measures and hydraulic stepless speed change, the lawn mower includes a noise reduction mowing device under the frame, including a height adjustment part and a mowing part; referring to Figure 5, the height adjustment part, press The parallelogram principle consists of a front fixed shaft (18a) and a rear fixed shaft 18c provided on the frame, and a front moving shaft 18b and a rear moving shaft 18d provided on the cutting disc 18 and a rod member connected thereto, and The wire rope 18h for pulling, the sector gear 18g, the pawl 18f and the height adjusting handle 15 are characterized in that: the front fixed shaft 18a and the rear fixed shaft 18c are arranged on the frame, and are arranged on the cutting disc. The upper front shaft 18b and the rear moving shaft 18d are four vertices of a parallelogram, and the corresponding sides are parallel and equal, so that the wire rope 18h is pulled by the height adjustment handle 15 and passed through the sector gear 18g. , the pawl 18f is used to give several upshift positions, and the connection between the front fixed shaft 18a and the rear fixed shaft 18c on the frame is always parallel with the front moving shaft 18b and the rear moving shaft 18d on the cutting disc, thereby It basically guarantees the up and down translation of the cutting disc to work normally; but in practice, it is necessary to adjust the length of the wire rope 18h. And formulation of the sector gear and the pawl 18f, 18g. Although the entire cutting disc is nearly parallel in each gear position, but still moves forward and backward, the engine main shaft 11 connected with the power belt 21 is centered, and the distance from the belt 21 to the first tool holder is longitudinally projected as a radius. Moved, and the belt 21 also has a height difference, which is oblique, but fortunately it can be used. It can be seen from Fig. 6 that since the sector gear 18g of the upshift position has a plurality of teeth, it is preferably 10 teeth, and there are 10 speeds, for example, can be adjusted at a height of 10-100 mm; or by a commonly used 25-85 mm. Several files are best requested by the customer. Referring to Figure 10, the mowing part of the power from the engine main shaft 11, through the belt 21 to the first seat, and then through the timing belt 23 to the second seat, so it is easy to drive the mower 20 work; as an improvement, see the figure 14 and FIG. 16, the lawn mower 20 is provided with two or more wind wings. In order to cut the grass, a plurality of cutting edges 20a are provided on the wind fins, and the two sides of the cutting edge are provided. The angle of the angle is not a right angle, and is preferably an acute angle of less than 60 degrees. Further, as an improvement, the lawn mower 20 is provided with a plurality of hexagonal holes, or further improved, and the lawn cutter 20 is provided with a plurality of Such as a honeycomb or a convex or concave such as the sharp point 7b, it is beneficial to change the audio frequency of the high-speed micro airflow flowing through the knife, that is, noise reduction.
所述的有降噪的割草装置的割草部分的图解设计和优选思维方法，是本发明的一项重要贡献。如前所述，原有的坐骑式割草机的一前一后两把刀的方案，用的是双面V形带，还用了三个张紧轮，因刀有前后，使割盘前后加大，致使整机加长。另一种原有的坐骑式割草机的两把刀，虽不是一前一后的，因两刀是反向转的，用的是较贵的双面同步带，还得用 两个同步张紧轮，这使得成本加大。能否找到用两把刀，不是一前一后，不使割盘前后加大，且不反向转，不用较贵的双面同步带，草不漏，刀不碰的途径，用何办法？回答是肯定的。用图解优选法：取条形刀20的两刀尖距为直径D，按两刀的回转轴即带轮中心(23a，23b)距为A，画出2个圆，参看图25，两圆相交的前部部分用填充影线表示，宽度B就是草不漏的重割幅B；再以A为直径作圆，圆周角恒为直角，因已设两把刀互垂，且是同步转动，故两把刀是圆周角的两条边，可另画多个圆周角来优选。有公式：B＝D-A。再参看图26，变动A，先按优选法0.618法取带轮距A＝0.618D，作图，再逐渐加大A，最大为接近D；图中所示是当刀快碰时的最大重割幅B及最小A。A影响割盘18的大小。又由公式：The graphical design and preferred method of thinking of the mowing portion of the noise-reducing mowing device is an important contribution of the present invention. As mentioned above, the original two-knife of the mount mower uses a double-sided V-belt and three tensioning wheels. Increased before and after, resulting in longer machine. The other two knives of the original mount lawn mower, although not one after the other, because the two knives are reversed, using the more expensive double-sided timing belt, you have to use Two synchronized tensioning wheels make this cost. Can you find two knives, not one after the other, do not make the cutting discs increase before and after, and do not reverse the rotation, do not need more expensive double-sided timing belt, the grass does not leak, the knife does not touch the way, what method ? The answer is yes. For the preferred method of drawing: take the two-tip distance of the strip-shaped knife 20 as the diameter D, and draw the two circles according to the rotation axis of the two-knife, that is, the center of the pulley (23a, 23b), and draw two circles. Referring to Fig. 25, the two circles intersect. The front part is indicated by a hatching, the width B is the heavy cut width B which is not leaking; the circle is made of A as the diameter, and the circumference angle is always a right angle. Since the two knives are set to hang each other and are synchronously rotated, Therefore, the two knives are two sides of the circumferential angle, and a plurality of circumferential angles can be drawn to optimize. There is a formula: B = D-A. Referring again to Fig. 26, the change A is first taken according to the preferred method 0.618 method to take the belt track A=0.618D, and then gradually increase A, the maximum is close to D; the figure shows the maximum heavy cut when the knife is fast touched. Frame B and minimum A. A affects the size of the cutting disk 18. Also by the formula:
取设计比率N＝A/D，一般地说，在74％-92％为佳。The design ratio N=A/D is taken, and in general, 74%-92% is preferable.
例如取74％，刀长D＝530，刀心距A＝390；割幅F＝D+A＝530+390＝920，有点少了，希望大点好；重割幅B＝D-A＝140，足够了。For example, take 74%, the cutter length D=530, the cutter center distance A=390; the cut width F=D+A=530+390=920, a little less, hope that the big point is good; the heavy cut width B=DA=140, enough.
作为另一实施例，取设计比率N＝A/D＝92％，刀长D＝530，刀心距A＝490；则割草机的割幅F＝D+A＝530+490＝1020，大点了，好；重割幅B＝D-A＝40，亦可用。As another embodiment, the design ratio N=A/D=92%, the cutter length D=530, and the cutter center distance A=490; the cutting width of the lawn mower F=D+A=530+490=1020, Big point, good; heavy cut width B = DA = 40, can also be used.
若取重割幅B＝D-A≤20，则有可能漏草，因草是左右晃的，且是被歪着让割盘压倒的，有时偶尔就有割不到的草。实用时，割盘内周与刀尖的间隙最好在3mm以上。If the weight cut width B=D-A≤20, it is possible to leak grass, because the grass is swaying left and right, and it is smashed to make the cutting plate overwhelmed, and sometimes there are occasionally cut grass. In practical use, the gap between the inner circumference of the cutting disc and the cutting edge is preferably 3 mm or more.
因为采用PROE-WILDFIRE软件，故可方便地变量画图，当然也可用其它软件。Because of the PROE-WILDFIRE software, it is easy to draw variables, and of course other software is available.

The function of the water tank is two-fold. In addition to cooling, it also uses heavy water to form heavy objects; since it is arranged at the front of the lawn mower, it has a counterweight function. The water in the sink is only added when it is used, because it does not count the weight of the transport; do not fill the tank with the added water, and half of it will do. The lower end of the lower elbow of the muffling tube 7 is connected to the muffler outlet. The water tank 2 is characterized in that a through hole is provided at a side thereof to match a lower curved pipe of the muffling pipe 7, and a water discharge port is provided at a bottom thereof. The muffling tube 7 is composed of a plurality of inner tubes 7a and an outer tube of a connecting piece and a plurality of microtips 7b arrays. The inner tube 7a is characterized by a honeycomb-shaped hexagonal eyelet, or a polygonal eyelet, or an elliptical and oblong hole; and the length of the inner tube of the plurality of segments is different in length and phase-to-phase; For example, if there is a long inner tube that is a three-quarters wavelength multiplied by a coefficient, then the adjacent inner tube is only a quarter-wavelength multiplied by its coefficient. In addition, the distribution of the plurality of perforations provided on the inner tube 7a is not uniform but is dense; the middle portion of the tube located on the length of the three-quarter wavelength multiplier is a quarter of the tube length The portion is a denser aperture, the remaining portion of the tube is a sparse aperture; and the aperture is characterized by a hexagonal aperture or a polygonal shape; the inner tube of the quarter-wavelength multiplied by the aperture The feature is that the distribution of the plurality of perforations provided thereon is not uniform but is sparse; three-eighths of the length of the middle portion of the segment is a denser perforation, and the remaining portions are The tube is a thin hole. The perforations are polygonal, preferably hexagonal; as an improvement, or the features of the perforations are polygonal, or hexagonal, or somewhat polygonal, or the characteristics of the perforations It is the microporous tip 7b, so it has a quarter-wave effect, a sparse wave effect and a honeycomb effect. The surface of the outer tube 7b is provided with a plurality of stamped and formed convex portions. It has a polygonal pyramid shape, that is, a multi-faceted pyramid shape, in particular a hexagonal pyramid shape, called a pointed ridge 7b; the pointed ridge is characterized in that it is hexagonal from the stamped root of the metal plate, and is reduced from the root to the top. The approximate ratio of width to depth is one to one, or to one to five. And at the top of each of said hexagonal pyramid-shaped tips on the face of said muffling tube is provided with micropores having an approximate diameter of 0.1 to 0.5 mm. On the surface of the inner tube 7a, as an improvement, or the perforations thereof may be modified to have a plurality of press-formed protrusions, which are polygonal pyramid-shaped, that is, multi-faceted pyramidal shape, especially hexagonal pyramidal shape, which may also be called Sharp, but its width to depth ratio is one to eight or eight, or to one to four to one. A plurality of pointed ridges form a sinuous structure, and the arrangement on each side is a honeycomb-shaped hexagonal polygon, or random, or elliptical, oblong, or irregular convex-concave; in the anechoic tube or It may be semi-filled with metal fiber or temperature-resistant non-metal material; or semi-filled with medium temperature resistant sound absorbing material such as porous sound absorbing material, or flexible material and film material. Or attached, or directly molded, or added with an azo blowing agent in the mold, the two components make the outer hardening and solidify. The porous materials such as fibers, foams, granules, and the like may be used alone or in combination with more or less. Fibers such as rock wool, or glass wool, or glass wool, especially ultra-fine glass wool; or foams, which are fireproofed by hot parts; or granules such as expanded perlite, porous terracotta bricks, and temperature resistant The fabric, felt to fill or attach; it is beneficial to improve the performance indicators, so that the comprehensive composition achieves the purpose of better noise reduction. A variety of materials have complementary high and low frequency sound absorption efficiencies. A lot of sharp points, adding more heat dissipation area; especially many microporous tips, not only have the microporous effect of noise reduction, but also have the potential to excrete excessive gas liquid. As an extension, many cusps can also be stretched, that is, outward to increase the heat dissipation area. A gasket that acts as both a heat insulator and a cushion can also be installed between the muffler and the engine. A gasket which serves as both a heat insulating mat and a cushion can also be assembled between the outlet of the muffler and the muffling tube 7. The muffling groove provided by the invention is provided with a plurality of large-area pointed areas, including a plurality of microporous sharp points, and has a sharp-pointing effect and a micro-hole effect. The utility model provides the muffler groove, which has the beneficial effects of increasing the noise elimination effect and improving the comprehensive performance of the muffler such as insertion loss, sound transmission loss, noise reduction amount and attenuation amount, and temperature drop. An inventive concept such as ghostly: if thick foamed foam is used, or as an improvement, comprehensive use of the various sound absorbing and damping materials described above and the use of numerous large-area pointed areas are provided in the lawn mower 18, see Fig. 21, and multiple lawn mowers such as the hood 1, see Fig. 11, such as the body 10c, see Fig. 12, and the noise reduction seat at the center of the upper part of the frame, and the rear of the car. The noise of the straw box can be expected to be safe and noise-reducing. In addition, for the personal protection of the rider, the accessory of the invention is provided with earplugs, soundproof cotton, earmuffs and an anti-sound helmet. A prosthetic foot protection plate with a rotating hinge is also provided on both sides of the middle of the mower. The prosthetic foot protection plate with rotating hinge provided on both sides of the mower is composed of a protective plate and a rotating hinge; the feature is that the protective plate is selected as a sound absorbing material, and the left and right sides are respectively One; but when it is sometimes necessary to place the side row of grass on the right side, the prosthetic guard is placed only on the left side; the shape of the shield is preferably a foot shape with two slightly larger waves, so it is enhanced. The foot should be careful to warn the association and the artistic image; the protective plate is preferably made of a softer but less soft Shore hardness of 65 to 95 materials such as rubber, polyurethane or polyvinyl chloride as the main board. The advantage is that when the level is working, for example, when placed on both sides of the cutting disc 18, the soft board is less likely to hurt the grass, and the soft board is more convenient for packing. The shield can also be made of a hard material. The protective plate is provided with a movable hinge, which is not limited to one or more or a flexible material, and is supplemented with a suitable limit, as long as the protective plate can be released and can work. Turn it up to make it easy to pack. As an extension or improvement, the protective panel can also be made detachable, put on during work, and removed when not working. In order to prevent problems before they occur, prevention is the main measure, and it is ensured that all the machines that are shipped in large quantities can pass the false foot detection. The shield can also be used in other parts of the fuselage, such as above the two rear wheels for protection. As still another embodiment, the whole vehicle can also be made of a soundproof material, which is not open, but has a top, Or fully enclosed sedan, to protect the sun, or full sound insulation. Foaming materials, porous sound absorbing materials, such as foamed cement or foamed plastics, or flexible materials and film materials, or double-layer blow molded parts; or attached, or directly molded, can be used throughout the body of the nose. , or an azo blowing agent is cured in the mold by two components to form an outer hard inner foaming; or a double layer is blown into a large part of a large area of a honeycomb and a pointed convex and concave shape, such as a machine Head and body. In summary, there are various beneficial effects of noise reduction measures: not only the different characteristic impedance of the sound absorbing material is used to reduce the reflected sound, but also the sound hole barrier of the small hole is used to reduce the high frequency noise. The earplugs have a plurality of pre-mode earplugs, and are molded with a soft plastic or soft rubber to form a certain geometry; or a foamed plastic earplug; therefore, there is a certain sound insulation and comfort. Moreover, since the soundproof cotton is made by chemical softening treatment with ultrafine glass wool, it is preferably 1-3 micrometers in diameter; and it is made into a small cone shape, so it is easy to plug to the ear; Sound insulation of sound cotton is better than ordinary cotton, and the sound insulation value increases with the increase of noise frequency, so it is more effective for isolating high frequency noise. Using soundproof cotton, it not only hinders language connection, but also clear language. The degree has improved. The earmuffs are earphone-like ear protection devices, or music earmuffs, so that work can be increased. The anti-sound helmet is a motorcycle helmet type, so it has a security function.
又因为所述的车架上方中部偏后的有降噪的车座亦有特色：车座包有厚厚的降噪泡沫材料，车座前后可移动；车座设有人坐下时接通，人离开时就不通的限位防护开关；或是非接触的人体感应器即传感器，故亦有保护作用。所述的车后方有降噪的收草箱10，设有2个挂钩17，其特征是S形，故便于挂在设在车架后的2个有销的挂架16上，销是活动地卡在S形里，故便于人工转角度以倒草和好取。如前所述的使两把刀同向驱动的单面同步带，在车间里发现太紧，而不好在生产线上安装；如果松了，又易偶尔跳步而不同步。作为改进，为了使同向驱动两把刀的单面同步带23好安装，参看图22，加设有张紧轮23c，所述的张紧轮23c与单面同步带23的无齿面接触，所以所述的张紧轮是无齿的圆轮；张紧轮装在张紧支架23d上，张紧支架23d活动地以固定的螺栓23e为杠杆支点而可调，故可由固定的小调节架23h上的调节螺栓23f和调定螺母23g来推定，故方便了安装，且消除了不同步现象。Moreover, because there is a noise-reducing seat on the upper part of the frame above the middle of the frame, the seat has a thick noise-reducing foam material, and the seat can be moved forward and backward; the seat is connected when the person sits down. The limit protection switch that is not accessible when the person leaves, or the non-contact human body sensor, that is, the sensor, also has a protective effect. The rear of the vehicle has a noise-reducing straw box 10, and two hooks 17 are provided, which are characterized by an S shape, so that it is easy to hang on two pinned hangers 16 disposed behind the frame, and the pin is active. The ground card is in the S shape, so it is convenient to manually turn the angle to pour grass and take it well. As mentioned above, the single-sided timing belt that drives the two knives in the same direction is found to be too tight in the workshop, and is not easy to install on the production line; if it is loose, it is easy to skip and synchronize. As an improvement, in order to mount the single-sided timing belt 23 that drives the two knives in the same direction, referring to Fig. 22, a tensioning pulley 23c is provided, and the tensioning wheel 23c is in contact with the flank of the single-sided timing belt 23. Therefore, the tensioning wheel is a toothless circular wheel; the tensioning wheel is mounted on the tensioning bracket 23d, and the tensioning bracket 23d is movably adjustable with a fixed bolt 23e as a lever fulcrum, so that it can be adjusted by a small adjustment The adjusting bolt 23f and the setting nut 23g on the frame 23h are estimated, so that the installation is facilitated and the unsynchronization phenomenon is eliminated.
作为改进，用隔音材料把整车制成不是敞蓬的，而是上有顶的，或全封闭轿车式的话，或作大型整体车，可利于挡晒或全隔音；或用几大块拼接。机头机身各处或整或拼都行。图11和图12所示的车头罩1和车身10c，亦可或整或拼。例如车身10c可分为前后两大块，后一大块可分可插合而作收草箱的上大盖。机头机身各处或整或拼都行还主要是指防噪结构的，如钢板模制拉伸为有蜂巢尖劈凸凹形的机头机身及割台，或铁板贴附注塑成形的蜂巢尖劈凸凹形大件，再配所述的隔音材料如发泡料，多孔吸声材料，发泡水泥或发泡塑料，或柔性材料及膜状材料；或贴附，或直接模压，或加偶氮发泡剂在模内双组分，以形成外硬内发泡而固化的如手提冰箱的结构；或双层的吹塑成有大面积的蜂巢及尖劈样凸凹形的各种大吹塑件，如机头和机身，再贴附厚发泡塑料。综上，故有各种减噪措施的有益效果：不但利用吸声材料不同的特性阻抗，来降低反射声，而且利用小孔低频绕射影区原理，设声屏障来减弱高频噪声。有降噪的车头罩1及消声的空气过滤网4的相连处有两个车灯3，既要注意粘缝不要太漏音，更要注意温升；若用灯是LED发光管，则温升没问题；当然，也可用其他类的灯。说到灯，就要说到电路；为了安全，在骑乘割草机上就得加装安全电路保护措施。参看图27，所述的安全电路，主要由单板机及仪表插件C4，引擎插件C1，扩展插件C5，点 火开关C2，蓄电池B1，直流继电器C3，动力输出PTO开关C6，电磁离合器C7，启动器ST，2个蜂鸣器，第一保险F1，第二保险F2，前照灯开关S0，左前照灯L1，右前照灯L2，驻车开关S1，N档开关S2，座位开关S3，挂集草箱开关S4，满草报警开关S5所组成，其特征是：所述的左前照灯L1和右前照灯L2，各由多个，例如4个发光二极管串联而成，也可加电阻；或各由多个发光二极管串并联，例如4串4并即各由16管组合而成，而且，最好多管沿弧形扇面排列，以利扩大视角范围；所述的座位开关S3，现作了新构思的非常规的设计；因为原有的座位开关，虽然座位未被坐下时座位开关是断开的，当驾驶员坐下后才能开动；若驾驶员离开座位后，有3-5秒的单板机延迟熄火控制，这听起来好象很安全了，其实不然；原有的座位开关有长期的很难解决的老大难问题，因当实际作业时，草地是颠簸的，屁股是抖动的，座椅是上下的，座位开关是忽通忽断的，特别是当驾驶员不慎跌落时，有3-5秒的单板机延迟熄火控制，要等3-5秒后才熄火；割草机行走速度在3.6至15公里/小时，既使取最慢速每秒一米，也要冲出3-5米，或十几米远才能停车，不难想象这对坠落的手脚或障碍物意味着什么；为了杜绝不安全的隐患，就需要新构思的非常规设计的可靠的而又不太贵的座位开关，所述的座位开关必须安全，当座椅上下抖动幅度很大时，座位开关也不能忽通忽断，而当真要断开时就要在0.1秒内马上断开；本发明提供的座位开关解决了这个老大难问题；参看图28，所述的座位开关S3，主要由设在座位9下的长滑杆S3-1，及设在与长滑杆相配的导轨的碳刷S3-2，以及座位弹簧9-2所组成，图示的位置是座位开关刚好断开时的剖面示意图；因为座位9下装有长滑杆S3-1，且插在导轨内并与碳刷相互配合，故长滑杆S3-1跟着座位9上下随动而***和拉出；所述的长滑杆S3-1呈长杆形，其截面若是带弧形的，例如圆形，管形的，则与长滑杆的所述的带弧形截面相配的碳刷S3-2的端面亦应是弧形的；，而若长滑杆的截面是方形的，例如四方形，多边形的，角铁形的，槽钢形的，则与长滑杆的所述的平截面相配的碳刷S3-2的端面亦应是平面的，以便相配处导电接触良好；所述的长滑杆S3-1的中部是导体，例如是铜的，而两端是绝缘体，例如是塑料的，且所述的导体上设有柔和的导线与开关S3的一个接线端子连接；而所述的碳刷上亦设有柔和的导线与开关S3的另一个接线端子连接；所述的碳刷后设有复位弹簧；因所述的长滑杆S3-1与座位随动，而可一并由装在座位9下的座位弹簧9-2来复位，当然亦可在长滑杆的下端设辅助复位弹簧；故当人坐在座位上时，所述的长滑杆S3-1的长杆形导体***和拉出尽管幅度再大，长杆形导体与碳刷总是接触良好的，而当人离开座位时，所述的长滑杆S3-1的长杆形导体在座位弹簧9-2的全力作用下，马上就拉出，其幅度大于人坐的晃悠的幅度区域，使长杆形导体与碳刷断开，而是长滑杆的绝缘部分与碳刷接触；所述的长滑杆S3-1的长杆形导体和长滑杆的下部的绝缘部分的接合处不能有台阶或高低不平，成型后最好作机加工，如车铣，以利于滑动而不卡。在熄火状态时，点火开关C2的M，G接通，主电路被短路，单板机及仪表插件C4和引擎插件C1的2号黑线短接，导致汽油发动机熄火；在运行状态时，点火开关C2的B，L接通，主电路被接通，单板机及仪表插件C4通过5号蓝线通电，引擎插件C1的第一端输入高电平，油门开关打开；油门档位处于N档位置时，N档开关S2断开，仪表显示灯亮。驻车状态时，驻车开关S1关闭，仪表上显示灯N亮；座位未被坐下时，座位开关S3断开，仪表上显示灯P亮。若在集草箱未挂的状态下，挂集草箱开关S4断开，集草箱警示灯亮，同时蜂鸣器U1发出连续的警报声；当在蓄电池B1电压 不足的状态下，接通主电路的电压过低，蓄电池指示灯亮；当闭合前照灯开关S0时，前照灯亮；在启动状态时，点火开关C2的B，L，S接通，主电路被接通，运行的功能均能实现；S端的暗红线接入单板机及仪表插件C4的4号线端，并通过单板机控制接收到4号线端的高电平信号，控制3号线端的输出高电平信号，接入直流继电器，使直流继电器C3导通，电源通过直流继电器流入到启动器ST，使汽油发动机启动。启动控制，是由单板机来判别是否符合以下5种启动状况：1.油门处于N档状态，N档开关断开，导致7号线端未能通过N档开关形成回路；2.动力输出PTO开关C6左端合，因PTO开关总是一组开关常开，一组开关常闭，图上位置为开关C6左端合的状态，此时割刀分离不工作，11号线端蓝线通过PTO开关C6左端割刀开关PTO输出形成回路；3.座位被坐下，座位开关被闭合，8号线端橙线通过座位开关输出形成回路；4.车辆被驻车时，驻车开关S1闭合，6号线端紫线通过驻车开关输出形成回路；5.集草箱或后盖板挂上时，挂集草箱开关S4压下，9号线端暗红线通过挂集草箱开关形成回路；所以，当点火开关处于启动状态时，4号线端暗红线输入高电平信号到仪表插件，就由单板机来判别是否符合以上5个信号要求，如果符合，则会在3号线端紫线输出高电平，使直流继电器C3导通，起动器工作。熄火控制：车辆在运行后的熄火控制；有5种信号或5种熄火信号；信号1.驻车开关，未驻车状态时，驻车开关OFF断开，6号紫线未能形成回路输出，驻车状态反之；信号2.N档开关，油门档位未在N档位置时，N档开关ON闭合，7号线端灰线形成回路输出，在N档位置反之；信号3.座位开关，座位未被坐下时，座位开关S3断开，8号线端橙线未能形成回路输出，座位被坐下反之；信号4.挂集草箱开关，若在集草箱未挂的状态下，挂集草箱开关S4断开，集草箱警示灯亮，同时蜂鸣器U1发出连续的警报声，9号暗红线端未能形成回路输出，集草箱或后盖板挂上时反之；信号5.动力输出PTO开关C6，因PTO开关总是一组开关常开，一组开关常闭，图上位置为开关C6左端合的状态，此时割刀分离不工作，11号线端蓝线通过PTO开关C6左端割刀开关PTO输出形成回路；而当PTO开关C6左端不合，右端合时，电磁离合器C7吸合，割刀结合，11号线端蓝线通过PTO开关C6左端割刀开关PTO输出未能形成回路，此时仪表上割刀工作显示灯亮；5种熄火信号是：1.上述5个信号中，PTO启动时，割刀结合，座位未被坐下，则发动机延迟3-5秒熄火；2.上述5个信号中，集草箱或后盖板未挂好，集草箱警示灯亮，同时蜂鸣器U1发出连续的警报声，发动机立即熄火；3.上述5个信号中，车辆被驻车时，驻车开关S1闭合，PTO开关C6左端不合，右端合时，电磁离合器C7吸合，割刀结合，则单板机令发动机立即熄火；4.上述5个信号中，未处于N档位置时，座位未被坐下，则发动机延迟3-5秒熄火；5.上述5个信号中，油门档位处在N档位置时，未驻车状态下，座位未被坐下，则发动机延迟3-5秒熄火；当车辆在满足上述一种或多种熄火信号时，通过单板机对上述信号的判别，再通过继电器控制，使2号线端的黑线短接，即使引擎插件C1的熄火线输出接地，导致汽油发动机熄火，延迟时间是通过单板机延时子程序来实现的。下面说几个控制。先说驻车控制，车辆被驻车时，驻车开关S1闭合，档位处于N档位置，座位未被坐下，PTO开关左端合，右端不合，电磁离合器C7不吸合，割刀不结合，集草箱和后盖板被挂上，发动机仍处于怠速状态。再说行驶控制，未驻车状态下，或在有时错误操作而致的驻车状态下，档位未处于N挡位置，座位被坐下，PTO开关左端合，右端不合，电磁离合器C7不吸合，割刀不结合 ，集草箱和后盖板被挂上，发动机不熄火。接着说刹车控制，在运行状态下，踩下刹车，未驻车状态下，档位处于N挡位置，座位被坐下，PTO开关左端合，右端不合，电磁离合器C7不吸合，割刀不结合，集草箱和后盖板被挂上，发动机仍然处于工作状态。下面说割草控制，在未驻车状态下，档位未处于N挡位置，或档位处于N档原地割草，座位被坐下，PTO开关左端不合，右端合，电磁离合器C7吸合，割刀结合，集草箱和后盖板被挂上，发动机仍然处于工作状态。最后叙述一下满草报警***，当集草箱草满时，满草报警开关S5被压下，10号线端褐色线通过满草箱报警开关S5形成回路，此时蜂鸣器U2发出警报声。As an improvement, the whole vehicle is made of soundproofing material, which is not open, but has a topped or fully enclosed sedan type, or a large integrated car, which can be used for blocking or full sound insulation; or with several large pieces of splicing. . The body of the nose can be used throughout the entire body. The front cover 1 and the body 10c shown in Figs. 11 and 12 can also be either integrated or assembled. For example, the body 10c can be divided into two large blocks in front and rear, and the latter one can be divided into a large cover for the straw box. The whole body of the nosepiece or the whole or the same is mainly referred to as the anti-noise structure. For example, the steel plate is stretched into a nose body and a header with a honeycomb tip and a concave and convex shape, or the iron plate is attached and injection molded. The honeycomb has a convex and concave large piece, and is further provided with the sound insulating material such as foaming material, porous sound absorbing material, foamed cement or foamed plastic, or flexible material and film material; or attached, or directly molded, Or a azo foaming agent is two components in the mold to form a structure of a portable refrigerator which is cured by external hard foaming; or a double layer is blown into a honeycomb having a large area and a pointed convex and concave shape. Large blow moldings, such as the nose and body, followed by thick foam plastic. In summary, there are various beneficial effects of noise reduction measures: not only the different characteristic impedance of the sound absorbing material is used to reduce the reflected sound, but also the sound hole barrier of the small hole is used to reduce the high frequency noise. There are two lights 3 at the junction of the noise-reducing front cover 1 and the muffling air filter 4. It is necessary to pay attention to the sticking seam not to leak too much, but also pay attention to the temperature rise; if the lamp is an LED light-emitting tube, then There is no problem with temperature rise; of course, other types of lights can be used. When it comes to lights, it is necessary to talk about circuits; for safety, safety circuit protection measures must be added to riding lawn mowers. Referring to Figure 27, the security circuit is mainly composed of a single board machine and an instrument plug-in C4, an engine plug-in C1, an extension plug-in C5, and a point. Fire switch C2, battery B1, DC relay C3, power output PTO switch C6, electromagnetic clutch C7, starter ST, 2 buzzers, first fuse F1, second fuse F2, headlight switch S0, left headlight L1, right headlight L2, parking switch S1, N-speed switch S2, seat switch S3, hanging grass box switch S4, grass-filled alarm switch S5, characterized by: said left headlight L1 and right front The lamp L2 is composed of a plurality of, for example, four light-emitting diodes connected in series, or a resistor may be added; or each of the plurality of light-emitting diodes is connected in series and in parallel, for example, 4 strings of 4 and 16 tubes are combined, and preferably The multi-tubes are arranged along the curved sectors to expand the range of viewing angles; the seat switch S3 is now a new concept of unconventional design; because of the original seat switch, the seat switch is broken although the seat is not seated Open, when the driver sits down, can start; if the driver leaves the seat, there is a 3-5 second single-board machine delaying the flameout control, which sounds like it is safe, but it is not; the original seat switch has Long-term difficult problem to solve, because when it is actually working The grass is bumpy, the buttocks are shaking, the seats are up and down, the seat switch is suddenly broken, especially when the driver accidentally falls, there is a 3-5 second single board machine delayed flameout control, wait After 3-5 seconds, the flame is turned off; the mower travels at a speed of 3.6 to 15 km/h. Even if the slowest speed is one meter per second, it must be 3-5 meters or more than ten meters to stop. Imagine what it means for falling hands, feet or obstacles; in order to eliminate unsafe dangers, you need a new and unconventional design of reliable and inexpensive seat switches that must be safe. When the amplitude of the upper and lower sides of the chair is large, the seat switch can not be turned off and on, and it should be disconnected within 0.1 seconds when it is really disconnected; the seat switch provided by the present invention solves this difficult problem; The seat switch S3 is mainly composed of a long slide bar S3-1 provided under the seat 9, a carbon brush S3-2 provided on a guide rail matched with the long slide bar, and a seat spring 9-2. The position is a schematic view of the seat when the seat switch is just disconnected; The long slide bar S3-1 is inserted into the guide rail and cooperates with the carbon brush, so the long slide bar S3-1 is inserted and pulled out following the seat 9; the long slide bar S3-1 is long rod If the cross section is curved, for example, circular, tubular, the end face of the carbon brush S3-2 matching the arcuate section of the long slide should also be curved; The cross section of the long slide bar is square, for example square, polygonal, angled, and channel-shaped, and the end face of the carbon brush S3-2 matching the flat section of the long slide should also be flat. The conductive contact is good at the matching; the middle of the long slider S3-1 is a conductor, such as copper, and the ends are insulators, such as plastic, and the conductors are provided with soft wires. Connected to one terminal of the switch S3; and the carbon brush is also provided with a soft wire connected to the other terminal of the switch S3; the carbon brush is provided with a return spring; S3-1 and the seat follow, but can be reset by the seat spring 9-2 installed under the seat 9, and of course, the auxiliary function can be set at the lower end of the long slide. a spring; therefore, when a person sits in a seat, the long rod-shaped conductor of the long slider S3-1 is inserted and pulled out, although the amplitude is large, the long rod-shaped conductor is always in good contact with the carbon brush, and when When the person leaves the seat, the long rod-shaped conductor of the long slide bar S3-1 is pulled out immediately under the full force of the seat spring 9-2, and the amplitude is larger than the amplitude area of the sway of the person sitting, so that the long rod shape The conductor is disconnected from the carbon brush, but the insulating portion of the long slider is in contact with the carbon brush; the joint of the long rod-shaped conductor of the long slider S3-1 and the insulating portion of the lower portion of the long slider cannot have a step or Uneven, it is best to machine after forming, such as turning and milling, to facilitate sliding without card. In the flameout state, the M, G of the ignition switch C2 is turned on, the main circuit is short-circuited, and the single-board machine and the instrument plug-in C4 and the black plug of the engine plug-in C1 are short-circuited, causing the gasoline engine to stall; in the running state, the ignition When B and L of switch C2 are turned on, the main circuit is turned on, and the single board machine and instrument plug-in C4 are energized by the 5th blue line. The first end of the engine plug-in C1 inputs a high level, the throttle switch is opened; the throttle position is at N. At the gear position, the N-speed switch S2 is turned off and the meter display light is on. In the parking state, the parking switch S1 is turned off, the indicator light N on the meter is on; when the seat is not seated, the seat switch S3 is turned off, and the indicator light P on the meter is on. If the grass collecting box switch S4 is disconnected in the state where the grass collecting box is not hung, the grass collecting box warning light is on, and the buzzer U1 emits a continuous alarm sound; when the battery B1 voltage is applied In the insufficient state, the voltage of the main circuit is too low, the battery indicator light is on; when the front light switch S0 is closed, the headlight is on; in the startup state, the B, L, S of the ignition switch C2 is turned on, the main circuit The function of the operation can be realized; the dark red line of the S end is connected to the 4th line end of the single board machine and the instrument plug-in C4, and the high level signal of the 4th line end is received through the control of the single board machine, and the control number 3 is controlled. The output of the high-level signal at the line end is connected to the DC relay, so that the DC relay C3 is turned on, and the power supply flows into the starter ST through the DC relay to start the gasoline engine. The start control is determined by the single board machine whether it meets the following five starting conditions: 1. The throttle is in the N position state, and the N position switch is disconnected, causing the 7th line end to fail to form a loop through the N position switch; 2. Power output The left end of the PTO switch C6 is closed. Because the PTO switch is always a group of switches normally open, one set of switches is normally closed. The position on the figure is the state of the left end of the switch C6. At this time, the cutter separation does not work, and the blue line of the 11th line passes the PTO. The switch C6 left end of the knife switch PTO output forms a loop; 3. The seat is seated, the seat switch is closed, and the orange line on the 8th line passes through the seat switch output to form a loop; 4. When the vehicle is parked, the parking switch S1 is closed. The purple line on the 6th line forms a loop through the parking switch output; 5. When the grass box or the rear cover is hung, the hanging grass box switch S4 is pressed down, and the dark red line at the 9th line end is formed by the hanging grass box switch. Therefore, when the ignition switch is in the startup state, the dark red line of the 4th line end inputs a high level signal to the instrument plug-in, and the single board machine determines whether the above five signal requirements are met. If it matches, it will be on line 3. The terminal purple line outputs a high level, so that the DC relay C3 is turned on. The actuator work. Flameout control: flameout control after the vehicle is running; there are 5 kinds of signals or 5 kinds of flameout signals; signal 1. parking switch, when the vehicle is not parked, the parking switch is OFF, and the 6th purple wire fails to form a loop output. The parking condition is reversed; the signal 2.N gear switch, the throttle gear position is not in the N gear position, the N gear switch is closed, the 7th wire end gray line forms the loop output, and the N gear position is reversed; the signal 3. the seat switch When the seat is not seated, the seat switch S3 is disconnected, the orange line on the 8th line fails to form a loop output, and the seat is seated instead; the signal 4. the set grass box switch is hanged if the grass box is not hung. Next, the hanging grass box switch S4 is disconnected, the grass box warning light is on, and the buzzer U1 emits a continuous alarm sound, and the dark red line end of 9 does not form a loop output, and when the grass box or the rear cover is hung, the reverse ; signal 5. power output PTO switch C6, because the PTO switch is always a group of switches normally open, a group of switches are normally closed, the position on the map is the state of the left end of the switch C6, at this time the cutter separation does not work, the line end of the 11th The blue line forms a loop through the PTO switch C6 left end cutter switch PTO output; and when the PTO switch C6 left end does not When the right end is closed, the electromagnetic clutch C7 is sucked and the cutter is combined. The blue line of the 11th line is passed through the PTO switch C6. The left end of the cutter switch PTO output fails to form a loop. At this time, the cutter work indicator light on the meter is bright; 5 kinds of flameout signals Yes: 1. Among the above five signals, when the PTO is started, the cutter is combined, the seat is not seated, and the engine is delayed by 3-5 seconds; 2. Among the above five signals, the grass box or the rear cover is not hung. Well, the grass box warning light is on, and the buzzer U1 emits a continuous alarm sound, and the engine immediately turns off the fire; 3. Among the above five signals, when the vehicle is parked, the parking switch S1 is closed, and the PTO switch C6 is not closed at the left end, the right end At the same time, the electromagnetic clutch C7 is sucked and the cutter is combined, and the single-plate machine causes the engine to immediately turn off; 4. Among the above five signals, when the seat is not in the N position, the seat is not seated, and the engine is delayed by 3-5 seconds. 5; in the above 5 signals, when the throttle position is in the N position, the seat is not seated in the unparked state, the engine is delayed for 3-5 seconds; when the vehicle meets one or more of the above When the flameout signal is used, the above signal is discriminated by the single board machine, and then passed through Controlling the end of line 2 of the short black line, even if the plug-in engine flameout lines C1 output ground, resulting in a gasoline engine stall delay time delay subroutine is implemented by the SBC. Here are a few controls. First, the parking control is mentioned. When the vehicle is parked, the parking switch S1 is closed, the gear position is in the N position, the seat is not seated, the left end of the PTO switch is closed, the right end is not closed, the electromagnetic clutch C7 is not engaged, and the cutter is not combined. The grass box and the rear cover are hung up and the engine is still idle. In addition to the driving control, in the no-parking state, or in the parking state caused by the wrong operation, the gear position is not in the N-range position, the seat is seated, the left end of the PTO switch is closed, the right end is not closed, and the electromagnetic clutch C7 is not engaged. , the cutter does not combine The grass box and the rear cover are hung up and the engine does not turn off. Then, the brake control, in the running state, the brake is pressed, in the non-parking state, the gear is in the N position, the seat is seated, the left end of the PTO switch is closed, the right end is not closed, the electromagnetic clutch C7 is not sucked, the cutter is not Combined, the grass box and the rear cover are hung and the engine is still working. The mowing control is described below.
