[0007] By adopting the above technical solution, when it is necessary to repair the mine land, the base is moved to the ground by the moving wheels. In the initial state, the soil-turning column falls into the first abutment groove under the action of gravity, and the driving member works. The driving member drives the sliding plate to slide down on the bracket. Since the two sliding plates are connected together by the connecting member, the driving member first drives the two sliding plates to slide toward the ground at the same time. At this time, the soil-turning column also descends with the sliding plate under the action of gravity until the soil-turning head at the bottom of the soil-turning column abuts against the ground; the driving member continues to drive the sliding plate and the abutment cylinder to slide down. At this time, the soil-turning column is limited by the ground, and the abutment block gradually moves away from the first abutment groove until the abutment block breaks away from the first abutment groove and is inserted into the second abutment groove. The soil-turning head can rotate while applying vertical pressure to the soil, and the soil-turning head has a better effect of turning the soil; finally, the driving member drives the sliding plate to rise, and at this time, under the action of gravity, the abutment block disengages from the second abutment groove and enters the first abutment groove, and the abutment block slides again in the first abutment groove, driving the soil-turning head to rotate and detach from the soil, thereby turning the soil again; the turning process only uses one driving member to drive the soil-turning head to apply pressure to the soil and rotate to dig the soil, and the driving member drives the soil-turning head to work once to achieve digging, and the whole process is quick and convenient, with high work efficiency and low implementation cost, achieving the effect of energy saving and emission reduction.

[0008] Optionally, the connecting member includes a plurality of screw rods and nuts, the screw rods pass through the two sliding plates together, the nuts are threadedly connected to the side walls of the screw rods, and the nuts can abut against the upper and lower surfaces of the sliding plates.

[0009] By adopting the above technical solution, when connecting two sliding plates, the screw rod is passed through the two sliding plates together, and then the nut on the screw rod is rotated to make the nut abut against the upper and lower surfaces of the sliding plates, thereby realizing the connection between the two sliding plates and facilitating the disassembly and assembly of the connecting plates; at the same time, the position of the nut on the screw rod can be rotated to change the distance between the two sliding plates, and the time for the soil turning head to press the land can be adjusted to meet different working environments.

[0010] Optionally, the driving member is a first oil cylinder, which is fixedly disposed on the top of the bracket, and a piston rod of the first oil cylinder is connected and fixed to one of the sliding plates.

[0013] By adopting the above technical solution, when the soil-turning head is pressed against the soil by the pressure of the second abutment groove, the pointed surface reduces the force-bearing area of ​​the end of the soil-turning head, which is beneficial for the soil-turning head to drill a hole. When the soil-turning head is rotated under force, the crushing pieces can expand the soil-turning range, thereby achieving the effect of improving the soil-turning effect.

When the rotating cylinder rotates, the particle flow groove on the ring plate will rotate to just below the particle outlet. At this time, the seeds in the grain storage box will pass through the particle outlet and pass through the particle flow groove and fall into the particle outlet pipe.

[0021] By adopting the above technical solution, after sowing the seeds, the second oil cylinder is turned on, and the piston rod of the second oil cylinder drives the mounting frame away from the base, and at the same time moves the base so that the flattening roller is against the tilled area. The base is moved repeatedly, and the flattening roller can rotate between the mounting frame, and the flattening roller fills and flattens the tilled area after sowing.

[0043] The implementation principle of the embodiment of the present application is:

[0044] When the ore land needs to be repaired, the base 1 is moved to the land through the moving wheel 11, and the piston rod of the first oil cylinder 5 is first turned on to extend. The first oil cylinder 5 drives the sliding plate 21 to slide down on the bracket 2, and the sliding plate 21 approaches the base 1. The soil turning column 4 also descends with the sliding plate 21 under the action of gravity until the soil turning head 42 at the bottom of the soil turning column 4 abuts against the land; the first oil cylinder 5 continues to drive the sliding plate 21 to descend, so that the abutment block 411 gradually moves away from the first abutment groove 221 and is inserted into the second abutment groove 222, and the abutment block 411 will abut against the second abutment groove 222 The inner walls abut and slide, and the second abutment groove 222 drives the abutment block 411 to slide while applying force to the abutment block 411, thereby driving the soil turning column 4 to rotate, and then driving the soil turning head 42 to rotate. The soil turning head 42 can also rotate while applying vertical pressure to the soil; then, the piston rod of the first oil cylinder 5 contracts, and at this time, under the action of gravity, the abutment block 411 breaks away from the second abutment groove 222 and enters the first abutment groove 221. The abutment block 411 is again subjected to the abutment force of the first abutment groove 221, driving the soil turning head 42 to rotate and break away from the soil, so as to realize digging and turning the soil again. When the first oil cylinder 5 is extended and retracted, the particle flow groove 1311 on the ring plate 131 will pass under the particle outlet 121 once, and the seeds in the grain storage box 12 will enter the particle outlet pipe 71 through the particle outlet 121. When the first oil cylinder 5 drives the soil turning head 42 to lift, the seeds just slide out of the particle outlet pipe 71 and fall into the dug pit. The soil turning and sowing can be carried out simultaneously, which reduces the cost and labor, improves the work efficiency, and achieves the effect of energy saving and emission reduction.
