TECHNICAL FIELD
[0001] The utility model relates to agricultural machinery technical field, concretely relates to the agricultural land leveler of steering. BACKGROUND
[0002] China is a big agricultural country, and the agricultural machinery operation effect is poor due to the low flatness of farmland. In recent years, China's field mechanization technology develops rapidly, and small-area farmland is integrated continuously, improving the land utilization rate. The leveling of sowing or transplanting operation can ensure that water resources, fertilizers or herbicides are evenly distributed on the field bottom, improve the utilization rate of fertilizers, effectively inhibit the growth of weeds, and thus improve the yield of crops and the efficiency and effect of mechanical operation.
[0003] The leveler is a kind of equipment to ensure the flatness of farmland before sowing. The traditional manual rough leveling technology cannot meet the leveling demand of large-area farmland, and the leveler can greatly improve the leveling precision and working efficiency, so it is widely used. However, the existing leveler can only perform leveling operation at a fixed angle and cannot change the angle left and right, which brings inconvenience to operation. At the same time, the existing leveler cannot mark and level the weeds or abandoned straw on the surface of the field, and the weeds, abandoned straw, etc. are easily accumulated in disorder on the field, which affects the sowing effect. In addition, the operation precision of the existing leveler is not high, and the leveling effect is not ideal. SUMMARY
[0004] The utility model aims at providing a simple structure of agricultural land leveler of steering.
[0005] The technical solution for realizing the utility model is as follows: the agricultural land leveler of steering, comprising a rack, a leveler and a leveling hydraulic cylinder are installed on the rack, the leveling hydraulic cylinder is connected to the leveler, a steering power device is further arranged on the rack, the steering power device is connected to the leveler, the connecting mechanism between the rack and the leveler, the connecting mechanism between the leveling hydraulic cylinder and the leveler, and the connecting mechanism between the steering power device and the leveler are all up-down and left-right swing connecting mechanisms.
[0006] Preferably, the up-down and left-right swing connecting mechanism is a universal joint bearing connecting mechanism.
[0007] Preferably, the steering power device is a steering hydraulic cylinder.
[0008] Preferably, a telescopic support rod is arranged on the rack, the telescopic support rod is connected to the leveler through the up-down and left-right swing connecting mechanism, and the telescopic end of the steering power device is connected to the telescopic end of the telescopic support rod.
[0009] Preferably, a weed marking claw is arranged at the bottom of the leveler.
[0010] Preferably, the grass-cutting claw is an isosceles triangle.
[0011] Preferably, the spacing between the grass-cutting claws is 5 to 15 cm.
[0012] Preferably, a satellite receiver is also included, which is mounted on the surface of a steerable farmland leveling machine.
[0013] Compared with the prior art, the significant advantages of this utility model are:
[0014] 1. The technical solution of this utility model has a simple structure and high economy. It can swing left and right to operate, which can effectively improve the work effect.
[0015] 2. This utility model can neatly arrange weeds or waste straw on the surface of the field, so that the weeds and waste straw can be evenly spread on the field, resulting in better sowing effect.
[0016] 3. This utility model, through satellite positioning, can not only achieve high positioning accuracy of the leveling machine, but also achieve high leveling operation accuracy and good horizontal effect.
[0017] The present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description
