Description
Technical field
The utility model relates to agricultural machinery technological field, is specifically related to a kind of radar control precision sower.
Background technology
Sowing is key operation link in the agricultural production, must be within short sowing farming season, and according to the agrotechnique requirement, seed broadcast in the field go, make crop obtain good development growth condition.The quality of seeding quality, with directly have influence on the emerging of crop, seedling is complete and seedling strong, and is thereby very large on the impact of output.Manual type is adopted in the tradition sowing, and operating efficiency is low, and labour intensity is large.Along with the development of agricultural mechanization is eliminated gradually.Mechanization sowing is the trend of agricultural development, is suitable for the seeding operation in bulk field, and is fully under way in China major grain producing area.China emphasizes agricultural mechanization always, and recently tremendous development has been arranged decades.Eighties of last century is risen the mechanization precision drilling gradually after the eighties.Compare with the Traditional Man sowing, the mechanization precision drilling has the following advantages: the one, and seeding quality is good, can guarantee seed at the field reasonable layout, and seeding quantity is accurate, and spacing in the rows is even, and seed level is consistent, is the creation optimum condition of growing of seed; The 2nd, can realize reducing cost, save a large amount of seeds, reduce seed costs, reduce simultaneously field thinning recruitment, guarantee the crop high and stable yields; The 3rd, high efficiency, speed are when 4～8km/h, and its spacing in the rows qualification rate reaches more than 85%; The 4th, uniformity is high, can reach the strong effect of Miao Qimiao.
But, existing precision sower mostly is suspension type, the ground wheel drive, and therefore have the following disadvantages: wheel drive is unstable 1,, and because of the operating environment restriction, there is certain problem of skidding in the ground wheel drive; 2, complicated mechanism needs manually conversion pairing sprocket wheel sometimes; 3, can't realize real-time adjustment, rely on operating personnel's technical merit during operation.
The utility model content
The purpose of this utility model is for deficiency of the prior art, provide a kind of automaticity high, utilize radar velocity measurement and adjust the radar control precision sower of seeding quantity according to speed.
For finishing above-mentioned purpose, the technical solution adopted in the utility model is: the radar control precision sower, comprise frame, kind of case and fertile case are installed on the frame, plant the case below seed placing device is installed, the ditching-fertilizing device is installed in fertile case below, and earthing compacting device is installed at the frame rear, it is characterized in that: the velocity radar, controller, proportion adjustable valve, hydraulic motor and the sowing driving shaft that connect successively also are installed on the frame; Described sowing driving shaft connects seed placing device.
Further, accident warning device is installed also on the frame, is connected with controller.
The utility model carries out speed monitoring by radar, adopts the fluid motor-driven sowing, so that seeding quantity can reach predetermined requirement, it has following characteristics: the blank of having filled up automatic control precision sower; By the control system Automatic Control, automaticity is high; Velocity radar equipment is installed on the facility, and at the volley realization speed detects; The shadow surface of radar beam is large, is easy to captured target, need not accurately aim at; The radar velocity measurement error is ± 1km/h to satisfy the requirement of precision drilling; Adjust seeding quantity according to the facility operating rate, conscientiously guarantee the spacing in the rows requirement; The seeding quantity regulation and control are accurate, and can realize by changing the seeding unit chip precision drilling of various crop.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Among the figure: 1, frame, 2, plant case, 3, seed placing device, 4, fertile case, 5, the ditching-fertilizing device, 6, earthing compacting device, 7, velocity radar, 8, controller, 9, the proportion adjustable valve, 10, hydraulic motor, 11, the sowing driving shaft.
Embodiment
Radar control precision sower as shown in Figure 1 comprises frame 1, and kind of case 2 and fertile case 4 are installed on the frame 1, plants case 2 belows seed placing device 3 is installed, and ditching-fertilizing device 5 is installed in fertile case 4 belows, and earthing compacting device 6 is installed at frame 1 rear; The velocity radar 7, controller 8, proportion adjustable valve 9, hydraulic motor 10 and the sowing driving shaft 11 that connect successively also are installed on the frame 1; Described sowing driving shaft 11 connects seed placing device 3.Frame 1 is born and being connected of tractor, and is responsible for each part is connected into facility.Plant case 2 and be used for taking up seed, be fed to seed placing device 3.Seed placing device 3 is used for leaving by agriculture requirement the seed furrow of degree of depth uniformity, and the field is arrived in the bunch planting of seed simple grain, and spacing in the rows is even, and replay rate, leakage sowing rate meet the demands.Seed placing device 3 is comprised of vacuum blower, airduct passage, smart amount feed mechanism etc., the vacuum blower high speed rotary, produce negative pressure, seed is attracted on the sowing disk by negative pressure, after disk turned an angle, negative pressure disappeared, and seed freely falls under shock effect by self gravitation, be slipped to the sowing position along discharging tube, realize the simple grain program request.Fertile case 4 is used for taking up fertilizer and by fertilizer apparatus fertilizer evenly being delivered to ditching-fertilizing device 5.Ditching-fertilizing device 5 is born trench digging and fertilizer is spread out over bottom of trench uniformly.Earthing compacting device 6 is responsible for inciting somebody to action soil layer and the compacting of kind subcovering last layer consistency of thickness after planting.Velocity radar 7 is used for the operating rate of monitoring facility.Proportion adjustable valve 9 links to each other with hydraulic motor 10, adjusts the fuel delivery of hydraulic motor by proportion adjustable valve 9, thereby adjusts the rotating speed of hydraulic motor 10.Controller 8 is used for changing according to the real work speed of facility the size of electric current, thereby adjusts proportion adjustable valve 9, realizes the fuel delivery regulation and control to hydraulic motor 10.Sowing driving shaft 11 adopts fluid motor-driven, by adjusting the rotating speed of hydraulic motor 10, has also just adjusted the rotating speed of sowing driving shaft 11, thereby realizes the regulation and control to seeding quantity.
In another embodiment: accident warning device also is installed on the frame 1, is connected with controller 8.Accident warning device is used for according to agriculture requirement, and to broadcast leakage, the faults such as obstruction are monitored and reported to the police, in order to fix a breakdown at any time.
Operation principle: by velocity radar, the operating rate of monitoring facility; According to the speed of monitoring, by the program of controller electromagnetic proportional valve is regulated; Proportioning valve links to each other with hydraulic motor, and the passing ratio valve is adjusted the liquid supply of hydraulic motor, thereby adjusts the rotating speed of hydraulic motor; Hydraulic motor links to each other with the sowing driving shaft, and program just can be controlled the rotating speed of sowing driving shaft like this, and the sowing driving shaft links to each other with seed placing device, so that seeding quantity realizes smart amount control.
