The first deep tillage plough 3 and the second deep tillage plough 5 adjacent to each other on the left and right are in a front-to-back staggered position. The second deep tillage plough 5 enables the bottom of the frame 1 to have an additional plow tool in a direction perpendicular to the cultivated land, which reduces the time for turning back and forth and improves work efficiency. In addition, the tillage forces of the first deep tillage plough 3 and the second deep tillage plough 5 on the land are relatively even, which is beneficial to reducing the pressure on the land, protecting the soil and maintaining soil fertility.

[0021] A slider 11 is fixedly connected to the upper surface of the second deep tillage plow 5, a mounting groove 401 is provided on the lower surface of the second mounting frame 4 to allow the slider 11 and the first hydraulic rod 6 to pass through, the first hydraulic rod 6 is fixedly arranged in the mounting groove 401, the end cover of the first hydraulic rod 6 is fixedly connected to the second mounting frame 4, a slide groove 402 is provided in the second mounting frame 4 to communicate with the mounting groove 401 and pass through the lower surface of the second mounting frame 4, the slider 11 extends into the slide groove 402 through the mounting groove 401, and the piston rod end of the first hydraulic rod 6 is fixedly connected to the slider 11.

[0022] On the basis of the above embodiment, four load-bearing universal balls 12 are fixedly provided on the upper and lower surfaces of the slider 11, and the four load-bearing universal balls 12 are distributed in a rectangular shape on the horizontal plane. The ball of the load-bearing universal ball 12 located at the top rolls with the top of the second mounting frame 4, and the ball of the load-bearing universal ball 12 located at the bottom rolls with the bottom of the second mounting frame 4. The four load-bearing universal balls 12 located at the bottom are evenly divided into two groups, and the two groups of load-bearing universal balls 12 are respectively arranged on the left and right sides of the top of the second deep tillage plough 5. The utility model provides rolling support through the load-bearing universal balls 12, which, on the one hand, improves the smoothness and stability of the first hydraulic rod 6 pushing the second deep tillage plough 5 forward, and on the other hand, improves the stability of the second deep tillage plough 5 in loosening the soil, and prevents the slider 11 from being deformed due to squeezing the second mounting frame 4.

[0023] See also Figure 1 The rear end of the frame 1 is provided with a covering wheel 8, the rear end of the frame 1 is hingedly connected to two connecting rods 7 arranged on the left and right, the two ends of the support shaft 801 are rotatably connected to the two connecting rods 7 respectively, the upper surface of the frame 1 is fixedly connected to two brackets 9, the top of the bracket 9 is hingedly connected to a second hydraulic rod 10, the end cover of the second hydraulic rod 10 is hingedly connected to the bracket 9, and the piston rod end of the second hydraulic rod 10 is hingedly connected to the upper surface of the connecting rod 7.

[0024] Based on the above embodiments, please refer to Figure 4 The covering wheel 8 includes a support shaft 801, a plurality of supporting wheels 802 fixedly sleeved on the outer wall of the supporting shaft 801 and arranged at intervals from left to right, and a plurality of connecting leaves 803 fixedly arranged on the outer wall of the supporting wheel 802 and evenly arranged in a ring shape about the axis of the supporting shaft 801. The connecting leaf 803 is bent into a spiral leaf structure by L-shaped steel, one right-angle side of the connecting leaf 803 is welded to the outer wall of the supporting wheel 802, and the other right-angle side of the connecting leaf 803 extends in a direction away from the supporting shaft 801. The covering wheel 8 adopts a pipe cage structure and has good structural strength.

[0025] The front end of the frame 1 is towed on a non-self-propelled agricultural machine such as a tractor's traction frame, and the hydraulic power of the first hydraulic rod 6 and the second hydraulic rod 10 is provided by the tractor's hydraulic system. Under the traction of the tractor, the soil covering wheel 8 rolls on the soil, and the rolling connecting blades 803 can flatten the soil loosened by the first subsoil plow 3 and the second subsoil plow 5 to achieve soil covering. The second hydraulic rod 10 is turned on, and the second hydraulic rod 10 drives the connecting rod 7 to rotate, so that the soil covering wheel 8 can be raised and lowered, and it can be selected whether to perform soil covering operation.

[0026] The first hydraulic rod 6 is turned on, and the first hydraulic rod 6 can drive the second deep loosening plow 5 to move. On the one hand, the front-to-back spacing between the first deep loosening plow 3 and the second deep loosening plow 5 can be changed, and on the other hand, the second deep loosening plow 5 can reach the same front-to-back position as the first deep loosening plow 3. The first deep loosening plow 3 and the second deep loosening plow 5 can first be extended into the soil together, and then the second deep loosening plow 5 moves forward under the drive of the first hydraulic rod 6, and the second deep loosening plow 5 loosens the soil first. After the loosening of the soil is completed, the first hydraulic rod 6 can drive the second deep loosening plow 5 to the same front-to-back position as the first deep loosening plow 3. At this time, there is no soil above the bottom tip of the second deep loosening plow 5, and the resistance of the first deep loosening plow 3 and the second deep loosening plow 5 to rise synchronously with the random frame 1 is greatly reduced.
