Embodiment 1

[0013] see Figure 1-3 , the specific embodiment is realized by adopting the following technical scheme, which includes supporting traveling wheels 1, rolling and bending rollers 2, roller support connecting frame 3, traction frame 4, hydraulic cylinder 5 and support frame 6, and described traction frame 4 is docked with the tractor, the roller support connecting frame 3 and the traction frame 4 are hingedly connected through the hitch 7, and the roller support connecting frame 3 can be adjusted to rotate around the hitch 7 through the hydraulic cylinder 5, and the hydraulic cylinder One end of 5 is fixed on the traction frame 4 through the first cylinder base 8 and is rotatably connected with the first cylinder base 8, and its piston shaft end is fixed on the roller support connecting frame 3 through the second cylinder base 9 and connected with the second cylinder base 9 Rotational connection and cooperation, the middle parts of the two ends of the rolling and bending roller...

Embodiment 2

[0016] see Figure 1-3 , the device is articulated with the tractor through the traction frame 4, the roller support connecting frame 3 and the traction frame are hinged through the hitch device 7, and the roller support connecting frame 3 can be adjusted to rotate around the hitch device 7 through the hydraulic cylinder 5, thereby adjusting the rolling Bending roller 2 position, rolling bending roller 2 is supported and connected by the rolling bearing on the roller support connecting frame 3. The rolling and bending roller 2 is mainly made of a 10mm thick steel plate bent into a cylinder 21 with a diameter of 300mm and a length of 3050mm, and 12 steel plates with a thickness of 9mm and a height of 100mm are evenly distributed on the outer surface of the cylinder 21 in the circumferential direction as rolling blades 22 Composition, the rolling blade 22 is welded and fixedly connected to the outer surface of the cylinder 21, and the shape of the rolling blade 22 is focused on ...

Embodiment 3

[0018] see Figure 1-3 , at an appropriate time before planting economic crops, the device is connected to the tractor through the traction frame 4, and during road transportation, the roller support connecting frame 3 and the rolling and bending roller 2 are lifted through the hydraulic cylinder 5 without contacting the ground , when entering the cover crop operation plot, put down the control roller support connecting frame 3 and the rolling and bending roller 2, at this time, the roller supporting connecting frame 3 and the horizontal main beam of the traction frame 4 are parallel, and the device is pulled by a tractor to cover crops in the field Walking upwards, the rolling and bending roller 2 is driven and rotated by the surface of the cover crop itself. When it encounters the stalk of the cover crop, it will roll and bend the stalk without breaking it. After the operation, the cover crop (rye, Sudan grass) will be flat and lodging shape, and died due to mechanical and p...

Abstract

The invention discloses a no-tillage cover crop grinding device. The no-tillage cover crop grinding device comprises supporting traveling wheels (1), a grinding and bending roller (2), a roller supporting connecting frame (3), a traction frame (4), a hydraulic oil cylinder (5) and a supporting frame (6), wherein the traction frame (4) is in butt joint with a tractor, the roller supporting connecting frame (3) and the traction frame (4) are hinged through a hooking device (7) and the roller supporting connecting frame (3) can be adjusted to rotate around the hooking device (7) through the hydraulic oil cylinder (5), and one end of the hydraulic oil cylinder (5) is fixedly arranged on the traction frame (4) through a first cylinder seat (8) and is rotatably connected and matched with the first cylinder seat (8). The device provided by the invention makes it possible that a chemical herbicide is not used or a small amount of the chemical herbicide is used. After operation, field cover crops are flatly and evenly attached to the earth's surface, so that a following no-tillage sowing operation is facilitated, thereby shortening the farming season and reducing use of the chemical herbicide.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a no-tillage cover crop rolling device. Background technique [0002] Planting cover crops before planting economic crops on no-tillage soil can further reduce soil erosion and enhance the soil's ability to store water and moisture; planting no-tillage cover crops will increase soil organic matter content, improve soil structure, and help increase crop grain Yield. Usually, chemical herbicides are used to kill cover crops, but the use of chemical herbicides to remove field cover crops will cause pesticide residue problems. At the same time, if chemical herbicides are not effective or the timing is not good, the cover crops will grow very large. The root system grows deep in all directions of the soil, which will easily cause congestion when the no-tillage seeder is sowing, and the sowing effect is not good, which does not meet the development requirements of susta...
