[0018] The present invention also discloses a method for tilling soil for agricultural cultivated land, which is performed by using a tilling machine for agricultural cultivated land, and comprises the following steps:

[0019] S1: The mounting frame is mounted on the vehicle frame by fastening bolts, and then the vehicle frame drives the mounting frame to move downward, so that the lever in the mounting shell at the lower side of the mounting frame is inserted into the soil to be turned over;

[0020] S2: Subsequently, drive the mounting frame to move along the area to be turned over by the vehicle frame, control the driving motor on the mounting frame to operate, and enable the soil-turning part to carry out soil-turning work;

[0021] S3: When the driving motor operates, it drives several mounting shells on the mounting block to rotate through the driving shaft, and then enables the lever on the mounting shell to rotate, so that the lever turns the soil during rotation;

[0022] S4: When the mounting shell rotates, it drives the moving frame to rotate around the driving shaft. The moving frame drives the rolling ball to move in the track groove through the connecting rod, so that the moving frame moves left and right reciprocally relative to the mounting shell. The moving frame drives each lever to swing left and right through the limiting part, so that the lever swings around the first screw rod as the center in the mounting shell, and enables the lever to swing left and right during the rotation of the mounting hole, so as to turn the soil between adjacent two levers and dial the stones in the soil from different angles, so that the stones in the soil can be easily turned out;

[0023] S5: After the soil-turning work is completed, when it is necessary to disassemble, repair or replace the lever, the user rotates the rotating rod, so that the worm on the rotating rod meshes and drives with the worm gear on the first screw rod. The first sleeve moves axially along the first screw rod, and the first sleeve drives the inserting pipe away from the mounting hole of the lever;

[0024] When the first screw rod rotates, the driving gear meshes and drives with the driven gear on the second screw rod. The second sleeve moves axially along the second screw rod, and the second sleeve drives the abutting plate to move towards the round connecting block through the connecting pipe;

[0025] S6: With the rotation of the first screw rod and the second screw rod, finally, the arc surface of the sliding rod at the end of the inserting pipe is placed in the mounting hole, and at this time, the abutting plate abuts against the outer wall of the round connecting block to position the position of the round connecting block at this time, ensuring that the sliding groove of the round connecting block is always in the same straight line as the gap between the two limiting rods of the limiting part during the replacement of the lever;

[0026] At this time, each lever is not directly dropped from the mounting shell under the support of the end of the sliding rod. The user directly pulls out the lever to be replaced and plugs in a new lever, and the quick replacement of multiple levers in the mounting shell can be realized.

[0027] Compared with the prior art, the present invention provides a soil-turning machine and a soil-turning method for agricultural tillage, and has the following beneficial effects:

[0028] 1. For the soil-turning machine and the soil-turning method for agricultural tillage, by rotating the rotating rod, the worm on the rotating rod meshes and drives with the worm gear on the first screw rod. The first sleeve moves axially along the first screw rod, and the first sleeve drives the inserting pipe away from the mounting hole of the lever, which is convenient for quickly releasing the limit on the lever, without the need to twist bolts for each lever in a cumbersome manner, and improves the disassembly, assembly and replacement efficiency of the lever.

[0029] 2. The agricultural tillage machine and tillage method elastically arrange a slide bar at the end of the insert pipe so that the arc surface of the end of the slide bar is placed in the installation hole, which is convenient for temporarily supporting the lever for releasing the restriction, so that the user can selectively remove the lever that needs to be replaced, and the practicability is strong.

[0030] 3. The agricultural tillage machine and tillage method for tilling soil are used. When the arc surface of the sliding rod at the end of the insert tube is placed in the installation hole, the abutment plate abuts against the outer wall of the circular block to locate the position of the circular block at this time, thereby ensuring that the sliding groove of the circular block is always in the same straight line with the gap between the two limit rods of the limit piece during the replacement of the lever, thereby preventing the circular block from moving randomly, resulting in the lever re-inserted from the circular block being unable to be accurately inserted into the two limit rods of the limit piece, thereby ensuring the installation effect of the lever.

[0031] 4. The agricultural tillage machine and tillage method drive the movable frame to rotate around the driving shaft when the mounting shell rotates, and the movable frame drives the rolling ball to move in the track groove through the connecting rod, so that the movable frame moves back and forth relative to the mounting shell, and the movable frame drives each lever to swing back and forth through the limiter, so that the lever swings in the mounting shell with the first screw as the center, and the lever can swing left and right while rotating with the mounting hole, so that the lever turns the soil between two adjacent levers, and the stones in the soil are turned out from different angles, so that the stones in the soil are easily turned out, and the soil between two adjacent levers can also be turned at one time, thereby improving the tillage efficiency.

10. A soil-turning method for agricultural cultivated land, which is carried out by using a soil-turning machine for agricultural cultivated land described in claim 9, characterized in that, The following steps are involved: S1: The mounting frame (1) is mounted on the vehicle frame by fastening bolts, and then the vehicle frame drives the mounting frame (1) to move downward, so that the lever (5) located in the mounting shell (4) at the lower side of the mounting frame (1) is inserted into the soil to be turned over; S2: Then, the vehicle frame drives the mounting frame (1) to move along the area to be tilled, and the driving motor (3) on the mounting frame (1) is controlled to operate so that the tilling part performs tilling work; S3: When the driving motor (3) is in operation, the driving shaft (2) drives the plurality of mounting shells (4) on the mounting block (201) to rotate, thereby causing the lever (5) on the mounting shell (4) to rotate, so that the lever (5) turns the soil during the rotation; S4: When the mounting shell (4) rotates, the movable frame (6) is driven to rotate around the driving shaft (2). The movable frame (6) drives the rolling ball (802) to move in the track groove (801) via the connecting rod (803), so that the movable frame (6) moves back and forth relative to the mounting shell (4). The movable frame (6) drives each lever (5) to swing back and forth via the limiter, so that the lever (5) swings in the mounting shell (4) with the first screw rod (9) as the center of the circle, so that the lever (5) can swing left and right while rotating with the mounting hole (10), so that the lever (5) turns the soil between two adjacent levers (5), and shifts the stones in the soil from different angles, so that the stones in the soil are easily turned out; S5: After the soil-turning work is completed, when the user needs to disassemble, repair or replace the lever (5), the user rotates the rotating rod (11) to engage the worm (111) on the rotating rod (11) with the worm gear (903) on the first screw rod (9) for transmission. The first sleeve (901) moves axially along the first screw rod (9), and the first sleeve (901) drives the insertion tube (902) away from the mounting hole (10) of the lever (5). When the first screw rod (9) rotates, the driving gear (904) meshes with the driven gear (121) on the second screw rod (12) for transmission. The second sleeve (122) moves axially along the second screw rod (12), and the second sleeve (122) drives the abutting plate (124) to move towards the circular connecting block (7) through the connecting pipe (123). S6: With the rotation of the first screw rod (9) and the second screw rod (12), finally, the arc surface of the sliding rod (9023) at the end of the insertion tube (902) is placed in the mounting hole (10). At this time, the abutting plate (124) abuts against the outer wall of the circular connecting block (7) to position the current position of the circular connecting block (7), ensuring that the sliding groove (701) of the circular connecting block (7) is always in a straight line with the gap between the two limiting rods (601) of the limiting member during the replacement of the lever (5). At this time, each lever (5) does not directly fall from the mounting shell (4) under the support of the end of the sliding rod (9023). The user can directly pull out the lever (5) to be replaced and re-insert a new lever (5), thus realizing the rapid replacement of multiple levers (5) in the mounting shell (4).
