Description

The tilting double careless wide cut hay mover of in the same direction pair of hay knife is driven without tensioning wheel ordinary straps

Technical field

The present invention relates to one kind for by garden, park and road, the hay mover that physical culture place cuts the grass on a lawn to be main to improve Purpose is to add safety circuit protection measures, makes and is conducive to mowing, noise reduction, the hay mover of environmental protection and safety, particularly a kind of The tilting double careless wide cut hay mover of in the same direction pair of hay knife is driven without tensioning wheel ordinary straps.

Background technology

Hay mower is widely used in the selected mode of hobby by people to mow.Due to the hay mover of hand push Mobility is poor, and when being mowed in practice, due to the anterior narrower swath of hay mover, so the phenomenon cut is cut and leaked in repetition often having Occur, benefit must be gone to cut, it is very arduous that operator's walking is mowed.If with sitting type, being also riding mower, then it is seated than station And feel different, but noise is big.If the prominent position that disseats of people, protects for original 3 seconds；Dan has rushed 9 meters or danger Jiu the meter per seconds of Suan 3.

Silencer is widely used as the silencing equipment of internal combustion engine particularly put-put, is arranged on cylinder cover Valve port reduces the noise of engine operation process.Countries in the world are to various traveling vehicles and the pole of the noise of hay mover Limit value has the regulation of correlation, and exhaust silencer is exactly such a device to reduce exhaust noise and life.The property of silencer Can evaluate mainly has acoustical behavior, the index such as aerodynamic quality and structural behaviour.It is low that the considerable part of internal combustion engine belongs to pulsating nature Frequency noise source, uses resistance or impedance again and property and micro-perforated plate muffler more.The silencer of common internal combustion engine in particular for The silencer of put-put is three-chamber silencer mostly, and noise elimination effect is limited；And outside must have larger containment envelope, But effect of itself not eliminating the noise.Moreover, its shell temperature rise is higher, hot, influence safety.If plus anechoic trap ought have improvement.

Artificial foot protection is in standard STD.BSI EN 836-ENGL 1997 and GB 4706.78-2005/IEC 60335-2- 77：2002 have related request.The mowing height of most hay movers is that have many gears adjustable, this peace to operating the pin of pedestrian The security regulations of strict control must be pressed entirely.This is typically to do prosthetic foot test.But the prosthetic foot test location of palpus test daily is more, covers Lid product quantity is very little.So that there is the hay mover of shipment, prosthetic foot safety is measured but by people individually, then all influence is cut Careless machine order.Improved idea is often to allow hay knife to be elevated at several millimeters of chassis.But because cutter is the part of elongate strip The sheet metal being folded over, due to tolerance, the reason for form and position tolerance and assembling cumulative errors, the point of a knife at two ends is in large quantities of actual productions In be difficult to ensure it is not high not low in a circumferential plane；Just in case occur thing difficulty avoid, but also to ensure ten thousand none go out Safety problem.A kind of inventive concept is being hovered such as ghost：If with thick soft foamed plastics by mowing table and hay mover many places Outsourcing it, it is expected to receive the effect of security protection and noise abatement, be really that my observations may contain a grain of truth.It is many again to work as safer using safety circuit protection measures.

In order to avoid phenomenon, two of original sitting type hay mover are cut in the leakage caused by two adjacent gaps of knife Knife, typically one in front and one in back.Figure 23 is refer to, this is one in front and one in back two transmissions signals of knife of original sitting type hay mover Figure, in figure, 23a is the belt pulley on the axle of the first knife, and 23b is the belt pulley on the axle of the second knife, and 11 is the belt of engine Wheel.The strip of two knives is mutually to hang down and reversely turn, so as to non-interference；It is two-sided V-belt, has also used three tensionings Wheel, more primary disadvantage is that before and after having because of knife, making to cut increasing before and after disk, causes wheel base to increase, and whole machine is lengthened, car revolution half Footpath becomes big, and longitudinal potentiality coefficient of stability is deteriorated, and cost is added, and these are all undesirable.Another original sitting type Two knives of hay mover, though it is not one in front and one in back, referring to Figure 24, because two knives are reversely to turn, so as to non-interference, to be Double-sided synchronous belt, also handy two synchronous tension wheels, this causes added cost.If driven without tensioning wheel and with ordinary straps, Being can reduces cost；But without tensioning, belt is just too loose without handy, unless primary and secondary belt wheel spacing further significantly shortens；It is double Unavoidable ground will have and cut rate again and cut with leakproof between hay knife, and multiplex pair of hay knife is smaller than knife diameter；So require double Hay knife is reversely rotated, and is required that double hay knives interlock and be provided with certain phase, and this requires the mutual invariablenes turning speed of double hay knives, just Use synchronous cog belt；But problem is that not only tension structure is complicated, synchronous cog belt and wheel cost are improved, more undesirable be because Double hay knives are reversely rotated and can not simultaneously be provided with the rear Lysimachia sikokiana and side Lysimachia sikokiana of wide cut, and in the market objectively needs one kind without tensioning Wheel ordinary straps are driven the tilting double careless wide cut hay mover of in the same direction pair of hay knife and are emerged.

The content of the invention

The present invention relates to one kind for by garden, park and road, the hay mover that physical culture place cuts the grass on a lawn to be main to improve Purpose does not add safety circuit protection measures still, resultant effect is not only improved mowing, and operation is comfortable, and variable speed has again Beneficial to noise reduction, environmentally friendly and safety, and be in order to be able to reduces cost；But without tensioning, belt is just too loose without handy, except non-master Secondary belt wheel spacing further significantly shortens；Unavoidable ground will have and cut rate again and cut with leakproof between double hay knives, multiplex pair of hay knife It is smaller than knife diameter；So require that double hay knives are reversely rotated, and require that double hay knives interlock to be provided with certain phase, this is just It is required that double mutual invariablenes turning speeds of hay knife are it is necessary to use synchronous cog belt；But problem is that not only tension structure is complicated, synchronous cog belt And wheel cost is improved, more undesirable is because the reverse rotation of double hay knives can not be while be provided with rear Lysimachia sikokiana and the side row of wide cut Grass, in the market objectively needs a kind of without the tensioning wheel ordinary straps tilting double careless wide cut mowing machine side of in the same direction pair of hay knife of drive Generation.

The technical scheme adopted by the invention to solve the technical problem is that hay mover to there is safety circuit protection measures and Safeguard protection has the pioneer of the hay mover of noise reduction and updates and perfect drive tilting in the same direction double cut without tensioning wheel ordinary straps The careless double careless wide cut hay mover of knife：

Have the riding mower of safety circuit protection measures, be add safety circuit protection measures have noise reduction measure and liquid Press the riding mower of variable speed, including safety circuit protection measures, and two propons for turning to of front-wheel of connection, connection Two driven back axles with hydraulic stepless speed change of trailing wheel, the vehicle

arcuately covering of the fan arrangement of best multitube expands angular field of view with profit； Described seat switch (S3), has now made unconventional design of new design；Because original seat switch, although seat not by Seat switch is to disconnect when sitting down, and can just be started after driver sits down；If after driver leaves seat, there is the list of 3-5 seconds Trigger postpones flame-out control, and this sounds and seems very safe, and actually this is not so；Original seat switch is individual long-term it is difficult to solution Hard nut to crack certainly, because when actual job, meadow is jolted, hip are shakes, and seat is upper and lower, seat switch It is that suddenly logical neglecting is broken, particularly when driver falls accidentally, the unit for having 3-5 seconds postpones flame-out control, after waiting 3-5 seconds It is flame-out；The hay mover speed of travel makes to take most at a slow speed one meter per second at 3.6 to 15 kilometers/hour, both, also to go out 3-5 meters, or ten Several meters could far stop, it is conceivable that this is to the trick fallen or barrier how it feels；Although having practised under normal conditions Think and flame-out control often is postponed using the unit for having 3-5 seconds, but in order to prevent unsafe hidden danger, it is necessary to new design The reliable and less expensive seat switch of non-conventional design, described seat switch must be safe, when seat is shaken up and down When amplitude is very big, seat switch can not neglect logical neglecting

Two bands of trailing wheel 6b of connection included by the described riding mower for having noise reduction measure and hydraulic stepless speed change The driven back axle 24 of hydraulic stepless speed change, as shown in figure 20, this is to remove multiple connecting screws and half back axle, and surplus half Back axle and expose two plunger displacement pumps and hydraulic control valve group of inside and the schematic elevation view of multiple gear, described back axle is comprising being located at Two semiaxis between two rear wheels, are provided with differential mechanism between two semiaxis, and thus differential mechanism is sequentially connected second upwards The stepless speed changing mechanism and brake apparatus of plunger displacement pump 24c and hydraulic control valve group, then through hydraulic control valve group connect the first plunger displacement pump 24b from Mechanism is closed, then via the belt 22 of the belt pulley in the rotary shaft of the first plunger displacement pump, transmits the power of engine spindle 11, it is special Levying is：The differential mechanism includes a pair of axle shaft gears, the planet wheel assembly between axle shaft gear, the star-wheel 24h of planet wheel assembly Most handy 2 star-wheels, and each tooth number of star is 12；Planet wheel assembly is erected on a larger gear wheel 24g, preferably its The number of teeth is 53；Described gear wheel 24g is engaged with intermediate speed pinion 24f, and best its number of teeth is 11；Described intermediate speed pinion 24f is coaxial with idler gear 24e and connects firmly, and best its number of teeth is 48；Described idler gear 24e and the speed change of the second plunger displacement pump Gear 24d is engaged, and best its number of teeth is 13, so foring decelerator and reinforcement, and forms differential mechanism and makes turning flexible. The plunger of the second described plunger displacement pump is most handy 5, and the plunger than the first plunger displacement pump is more, and the cylinder diameter of each plunger is just larger, Pretend as oil motor, output torque is just larger.Because the coaxial of the change-speed gearing of the second plunger displacement pump is provided with brake apparatus Brake disc, be provided with friction plate, brake bar and spring and constitute brake apparatus on the back axle 24 near brake disc, therefore just It is connected in foot brake device 12 and Hand brake apparatus 13 in the middle part of vehicle frame；The foot brake device 12 and Hand brake apparatus 13 of this car be actually Same set of mechanism.In hydraulic control valve group between the second plunger displacement pump and the first plunger displacement pump, Shift lever is provided with, on the one hand regulation and control hydraulic control Oil inlet and outlet in valve group, the angle on the other hand changing the plunger head inclined-plane of the first plunger displacement pump changes output speed, therefore It is easy to be connected with drive shift 14 and reverse drive gear 14b in the middle part of vehicle frame, to constitute stepless speed changing mechanism；When neutral gear, the first plunger The angle on the plunger head inclined-plane of pump is zero, idle running and without output, the first plunger displacement pump serves the effect of clutch；Drive shift 14 It is connected with reverse drive gear 14b, manipulates stepless speed changing mechanism；When drive shift 14 is stepped on, the second plunger displacement pump and the first plunger displacement pump it Between hydraulic control valve group on Shift lever, regulation and control hydraulic control valve group on oil inlet；Step on deep, make the big then speed of oil inlet fast；Step on Shallow, the small then speed of oil inlet is slow, therefore realizes stepless shift；When reverse drive gear 14b is depressed, in the second plunger displacement pump and the first plunger displacement pump Between hydraulic control valve group on Shift lever reversely, make oil inlet and outlet in regulation and control hydraulic control valve group reversely, invert the second plunger displacement pump, Decelerator below and differential mechanism reversion are driven, is allowed to move backward.Because the second plunger displacement pump is herein actually when oil motor, It drives change-speed gearing 24d to be engaged with series of gears, so as to drive two semiaxis and trailing wheel 6b.In the second plunger displacement pump and first In hydraulic control valve group between plunger displacement pump, parking bar is additionally provided with, regulates and controls the interior hydraulic fluid port of hydraulic control valve group, when parking position is pulled, parking The D-shaped bar of the inside of bar hinders interior hydraulic fluid port.Inlet valve 24k is provided with inside described driven back axle 24 to connect outer oil box, Therefore convenient lubrication；Permanent magnet 24j is additionally provided with described driven back axle 24, or uses horseshoe magnet, because of You Ci rotation streams And effect is good, or many places are located at, therefore beneficial to holding the iron filings that each steel and iron parts are mixed into oil after permanent abrasion.

Again because of the band dual fail-safe above the four-wheel included by the riding mower for having noise reduction measure and hydraulic stepless speed change The vehicle frame of thick stick, as shown in Fig. 2 bumper is provided with front of car, it is characterized in that：Described bumper is parallel bars, or three, or It is more, and be curved two per thick stick, support support at middle straight pipe or square tube, and at least two；Parallel bars should be more than single Insurance；Used as improvement, described support is not rigidity, but elasticity, such as with spring, or elastomeric material such as rubber or poly- Ammoniacum, therefore be more conducive to buffer.

Again because there is the noise reduction that has below the vehicle frame included by the riding mower of noise reduction measure and hydraulic stepless speed change Mowing-apparatus, including height adjusting part point and mowing part；Referring to Fig. 5, height adjusting part point, by parallelogram principle, by Preceding dead axle (18a) and rear dead axle 18c on vehicle frame are located at, and are located at the preceding moving axis 18b and rear moving axis 18d cut on disk 18 and therewith The rod member for mutually interlocking, and for the steel wire rope 18h of pulling, sector gear 18g, ratchet 18f and heightens handle 15 and is constituted, its It is characterized in：The described preceding dead axle 18a and rear dead axle 18c that are located on vehicle frame, and it is located at preceding moving axis 18b and the rear moving axis cut on disk 18d is four summits of parallelogram, and its corresponding side is parallel and equal two-by-two, so, in any case by heightening Handle 15 pulls steel wire rope 18h, and by sector gear 18g, and ratchet 18f heightens gear to several, preceding fixed on vehicle frame The line of axle 18a and rear dead axle 18c, is always parallel with the preceding moving axis 18b and rear moving axis 18d that cut on disk, so as to basic On ensure that the upper and lower translation and normal work for cutting disk；But the length of steel wire rope 18h, and sector are still mixed up when practical Take turns the allotment of 18g and ratchet 18f.Though it is whole cut disk and be almost be in each gear it is parallel, but it is front and rear have movement, be with dynamic The engine spindle 11 that power belt 21 is ined succession is the center of circle, and being moved for radius apart from longitudinal projection for the first tool rest is passed to through belt 21 Dynamic, and belt 21 also has difference in height, is oblique, can also fortunately use.As can be seen from Figure 6, because heightening the described fan of gear Shape gear 18g has multiple tooth, and now preferably 10 teeth, there is 10 grades, for example, can cut height in 10-100mm to adjust；Or by conventional 25-85mm, Several shelves are divided preferably to press customer requirement.Referring to Figure 10, the power of mowing part passes to first from engine spindle 11 through belt 21 Tool rest, then synchronized band 23 passes to the second tool rest, therefore is easy to drive hay knife 20 to work；As improvement, referring to Figure 14 and Figure 16, Described hay knife 20 is provided with two or more wind wings, and grass is twined in order to cut off, and multiple cutting edges are provided with described wind wing 20a, the angle on the two sides of described cutting edge is not right angle, preferably less than 60 degree of acute angle；It is further used as improving, it is described Hay knife 20 is provided with multiple hexagonal holes, or further improves, and described hay knife 20 is provided with multiple such as honeycombs or such as point The convex-concave of 7b is split, therefore the audio frequency i.e. noise reduction of the high speed Tiny pore of knife is flowed through beneficial to change.

The graphical designs and preferred method of thinking of the mowing part of the described mowing-apparatus for having noise reduction, are of the invention one Item significant contribution.As it was previously stated, one in front and one in back two schemes of knife of original sitting type hay mover, are two-sided V-belts, Three tensioning wheels are also used, before and after having because of knife, has made to cut increasing before and after disk, caused whole machine to lengthen.Another original sitting type cuts Two knives of careless machine, though it is more expensive double-sided synchronous belt because two knives are reversely to turn one in front and one in back not to be, it is also handy Two synchronous tension wheels, this causes added cost.Can find with two knives, not be one in front and one in back, not make to cut increasing before and after disk, And do not turn reversely, without more expensive double-sided synchronous belt, grass does not leak, and what method is the approach that knife is not touched useAnswer is yes.With Diagram optimum seeking method：Two point widths of strip-shaped cutter 20 are taken for diameter D, the gyroaxis by two knives be belt wheel center (23a, 23b) away from for A, draws 2 circles, and referring to Figure 25, the intersecting front part filling hachure of two circles is represented, width B is exactly careless leak-free weight swath B；Make to justify as diameter with A again, it is right angle that angle of circumference is permanent, is mutually hung down because having set two knives, and is synchronous axial system, therefore two knives are circumference Two sides at angle, can separately draw multiple angles of circumference and come preferred.There is formula：B=D-A.Referring again to Figure 26, A is changed, first by optimum seeking method 0.618 method takes band wheelspan A=0.618D, mapping, then is gradually increased A, is to the maximum close to D；It is when knife is touched soon shown in figure Maximum weight swath B and minimum A.The size of disk 18 is cut in A influences.Again by formula：

Designed ratios N=A/D is taken, in general, is preferred in 74%-92%.

74%, knife D=530 long are for example taken, cutter heart is away from A=390；Swath F=D+A=530+390=920, it is somewhat few, Wish a little bigger good；Heavy swath B=D-A=140, it is enough.

As another embodiment, designed ratios N=A/D=92%, knife D=530 long are taken, cutter heart is away from A=490；Then mow The swath F=D+A=530+490=1020 of machine, it is a little bigger, it is good；Weight swath B=D-A=40, also can use.

Because grass is that left and right is shaken, and cut disk and overwhelmed by askew allowing if taking weight swath B=D-A≤20, it is likely that leakage grass , just have once in a while sometimes cut less than grass.When practical, disk inner circumferential is cut with the gap of point of a knife preferably in more than 3mm.

Because using PROE-WILDFIRE softwares, therefore easily variable can draw, other softwares can be also used certainly.

Disappear because of the forward band in the vehicle frame top included by the riding mower for having noise reduction measure and hydraulic stepless speed change again The engine of sound track and the vehicle cover for having noise reduction, as shown in Fig. 4 and Figure 10, engine are drawn to see clearly to exempt to block to have saved；Eliminate the noise The enlarged drawing of groove is as shown in Figure 18 and Figure 19；The anechoic trap that the present invention is provided, contains hush tube 7 and tank 2；Described hush tube In tank 2 described in 7 lower bend immersion, therefore there is cooling effect.The effect of described tank is to kill two birds with one stone, except cooling Outward, also with water for weight；Because it is located at hay mover front portion, therefore there is counterweight effect.The water of tank face the used time just plus, because of this not Meter hauled weight；Plus water should not fill it up with groove, have half just.The lower end of the lower bend of described hush tube 7 and noise elimination Device outlet connects.Described tank 2 is characterized in that its side is provided with through hole, so as to the lower bend phase with described hush tube 7 Match somebody with somebody；Its bottom is provided with dewatering outlet.Multiple wedge 7b arrays of the described hush tube 7 by multistage inner tube 7a and connection sheet and containing micropore Outer tube composition.There is inner tube in outer tube, described inner tube 7a is characterized in which is provided with cellular hexagon eyelet, or polygon Shape eyelet, or oval and oval eyelet；And the inner tube length of multistage is different and alternate length；For example have one section be four/ The inner tube more long of three wavelength multiplying factors, then it is adjacent be only its quarter-wave multiplying factor inner tube.In addition, described is interior The distribution of multiple eyelets that pipe 7a is provided with is not uniform but has density；Positioned at one section of 3/4ths wavelength multiplying factors The position of a quarter pipe range at the middle part on pipe is closeer eyelet, is thinner eyelet on the pipe of remaining part；And its Eyelet is characterized in hexagon eyelet or many prismatics；The feature of the inner tube of the quarter-wave multiplying factor of described eye It is that the distribution of the multiple eyelets which is provided with is not uniform but has density；Eight of middle part on this section of pipe/ The position of three pipe ranges is closeer eyelet, is thinner eyelet on the pipe of remaining part.Described eyelet be it is polygonal, most It is well hexagonal；Used as improvement, or its eyelet is characterized in many prismatics, or six prismatics, or have a fabrication flange It is polygonal；Or its eyelet is characterized in the described wedge 7b for having micropore, therefore with quarter-wave effect and density Wave effect and honeycomb effect.On the face of described outer tube 7b, many stamping projections are provided with, are polyhedral cone in multi-prism taper Body shape, particularly hexagonal pyramid shape, referred to as wedge 7b；Described wedge is characterized in, its from the root of the punching press of metallic plate be six It is angular, it is to reduce from root to top, substantially its breadth depth ratio is one to one, or to one to one point five.And in described hush tube Face on each described in hexagonal pyramid shape wedge at the top of be provided with micropore, its approximate diameter is advisable at 0.1 to 0.5 millimeter.

simultaneously Connection, such as 4 strings 4 are simultaneously respectively combined by 16 pipes, and, the arcuately covering of the fan arrangement of best multitube expands angular field of view with profit； Described seat switch S3, has now made unconventional design of new design；Because original seat switch, although seat is not sat Seat switch will be to disconnect when lower, can just be started after driver sits down；If after driver leaves seat, there is the veneer of 3-5 seconds Machine postpones flame-out control, and this sounds and seems very safe, and actually this is not so；Original seat switch has long-term very scabrous Hard nut to crack, because when actual job, meadow is jolted, hip are shakes, and seat is upper and lower, and seat switch is to neglect Logical to neglect what is broken, particularly when driver falls accidentally, the single board computer for having 3-5 seconds postpones flame-out control, is just put out after waiting 3-5 seconds Fire；The hay mover speed of travel makes to take most at a slow speed one meter per second at 3.6 to 15 kilometers/hour, both, also to go out 3-5 meters, or more than ten Rice could far stop, it is conceivable that this is to the trick fallen or barrier how it feels；In order to prevent unsafe hidden danger, just The reliable and less expensive seat switch of the non-conventional design of new design is needed, described seat switch must be safe, when When the upper and lower jitter amplitude of seat is very big, seat switch can not neglect logical neglecting and break, and will be in 0.1 second at once when disconnecting surely Disconnect；The seat switch that the present invention is provided solves this hard nut to crack；Referring to Figure 28, described seat switch S3, mainly By the slide bar
