[0021] The push rod 5 penetrates the drum 3 radially and can slide inward and outward. A horizontal front-to-back direction sliding rod 8 is fixed to one end of the push rod 5 located on the inner side of the drum 3. Guide plates 9 are fixed to the inner side surfaces of the vertical plates 2 on the front and rear sides located inside the drum 3. The guide plates 9 are annular plates.

The sliding rod 8 contacts the inner edge surfaces of the guide plates 9 on the front and rear sides. A push plate 10 is fixed to the outer end of the sliding rod 8. A compression spring is arranged between the push plate 10 and the drum 3. The compression spring causes the sliding rod 8 to always be subjected to an outward extrusion force.

[0022] A material blocking layer 11 is fixed to the outer end of each push plate 10, and both ends of the material blocking layer 11 are fixedly connected to the adjacent flipping plate 4 respectively, and the middle part of the material blocking layer 11 is fixedly connected to the push plate 10 by bolts.

[0023] A box body 12 is fixed on the right side of the retaining plate 6, and the upper end of the vertical rod part of the L-shaped rod 7 passes through the lower end surface of the box body 12 to the cavity. Two left and right sliders 13 that can move up and down are arranged in the box body 12. The L-shaped rod 7 is alternately fixed on the sliders 13 on the left and right sides. A through hole 14 is opened in the middle of each slider 13. A first motor 15 is fixed on the right side of the box body 12. The rotating shaft of the first motor 15 passes horizontally to the right into the cavity of the box body 12. Two left and right cams 16 are fixed on the rotating shaft of the first motor 15. The far rest ends of the two cams 16 face oppositely and are respectively placed in the left and right through holes 14. When the first motor 15 drives the cam 16 to rotate, it can drive the sliders 13 on the left and right sides to move up and down alternately.

[0024] A box body 17 is fixed at the upper end of the support plate 1, and the upper end of the box body 17 is open. A water suction pipe 18 is arranged on the right side of the box body 17. One end of the water suction pipe 18 passes through the cavity of the box body 17, and the other end passes downward through the support plate 1 to the right side of the L-shaped rod 7. A water suction pump is arranged in the middle of the water suction pipe 18, and the water suction pump can extract the liquid in the box body 17 through the water suction pipe 18. A sprinkler head 19 is fixed to one end of the water suction pipe 18 located on the right side of the L-shaped rod 7.

[0025] A vertical adjustment rod 20 is fixed to the left end of the support plate 1. The adjustment rod 20 is provided with a plurality of pin holes 21 penetrating the front and rear end surfaces from top to bottom. A pin 22 is arranged in the pin hole 21. A U-shaped rod 23 is arranged at the outer end of the pin 22. The U-shaped rod 23 opens to the right and has two vertical rod parts respectively provided with transverse holes. The pin 22 passes through the transverse hole and is threadedly connected at both ends with nuts whose outer diameter is larger than the diameter of the transverse hole.

[0026] A second motor is fixed on the vertical plate 2 at the rear side, the second motor shaft passes through the inner side of the vertical plate 2 and is fixed with a pulley, a belt is provided at the front end of the outer edge of the drum 3, the belt is connected to the pulley, and the second motor drives the drum 3 to rotate through belt transmission.

[0027] The left end of the baffle plate 6 is provided with a crushing layer 26, which is composed of a plurality of conical blocks with their tips facing left.

[0028] It is worth mentioning that in order to prevent the blocking layer from being damaged by sharp objects in the soil, the blocking layer 11 is made of a flexible wear-resistant rubber material with a certain thickness; In order to ensure that the push plate 10 has sufficient thrust to push the soil to the right, it is necessary to use a compression spring with greater elasticity, or to set multiple compression springs along the length direction of each push plate 10. At the same time, it is necessary to use a second motor with greater torque to ensure that the torque of the second motor is sufficient to drive the roller 3 to rotate to overcome the elastic force of multiple groups of compression springs.

[0029] When the present invention is in use, the left end of the U-shaped rod 23 is fixedly connected to the walking device, and then the turning depth of the turning plate 4 to the soil is determined according to the fixed height of the walking device and the U-shaped rod 23. Specifically, the pin shaft 22 can be placed in the pin shaft hole 21 at different heights to insert the lower turning plate 4 into the soil layer, and then the two ends of the pin shaft 22 are fixed to the U-shaped rod 23 by nuts, and then the cavity is filled with soil conditioner through the upper end opening of the box body 17; the first motor 15, the second motor and the water pump are started to make the walking device The pulling device moves as a whole. During the movement, the flipping plate 4 rotating counterclockwise with the roller 3 can flip the soil backwards. Because the push rod 5 always makes the slide bar 8 contact with the inner edge surface of the guide plate 9 under the action of the compression spring, the inner edge surface of the guide plate 9 is a spiral surface. When the push rod 5 rotates to the lower position, it can be located at the innermost side of the roller 3. At this time, the amount of soil that can be accommodated by the flipping plate 4 is the largest. When the flipping plate 4 rotates to the right side with the roller 3, the radius of the inner edge surface of the guide plate 9 suddenly increases, and the push rod 5 can be under the elastic force of the compression spring. The push plate 10 and the retaining layer 11 can push the soil in the interval of the flipping plate 9 outwards, increasing the kinetic energy of the soil when it is flipped to the right. At the same time, the retaining layer 11 can shake off the residual soil to prevent the soil from sticking to the flipping plate 4. The soil thrown to the right can hit the crushing layer 26 on the left end face of the retaining plate 6, so that the compacted soil blocks are crushed after being hit by the crushing layer 26, and then fall onto the L-shaped rod 7. Since the L-shaped rod 7 is arranged at intervals, the rocks in the soil that cannot be hit and crushed can be The large particles of impurities such as lumps are screened and made to stay above the cross bar of the L-shaped rod 7. Since the first motor 15 can drive the cam 16 to drive the two sliders 13 to move up and down alternately, the two adjacent L-shaped rods 7 can move up and down alternately. The alternating up and down movement of the L-shaped rod 7 can shake the soil above it, greatly improving the screening efficiency. Finally, the water pump can spray the soil conditioner in the water tank 17 on the soil after turning over through the water pump pipe 18 and the sprinkler nozzle 19, completing the soil improvement operation.

[0030] The present invention improves the existing soil turning plate by adding a push rod 5, a push plate 10 and a material blocking layer 11 in the interval of the turning plate 4. The push rod 5 can be retracted inwardly during the rotation of the roller 3 by utilizing the guiding effect of the guide plate 9, and can be quickly released and popped outward at the right side of the roller 3, so that the soil contained in the turning plate 4 can be quickly thrown outward, thereby increasing the kinetic energy of the turned soil and cooperating with the crushing layer to greatly improve the crushing efficiency of the soil; the material blocking layer 11 blocks the soil from contacting the bottom of the turning plate 4, so that the soil will not be stuck in the interval of the turning plate 4, and the compression spring is released to drive the push plate 10 to the material blocking layer 11, so that the soil is thrown out and the blocking layer is also pushed out. The material layer 11 is shaken to further improve the separation efficiency between the turning mechanism and the soil, greatly reducing the subsequent manual cleaning cost; the impurities in the soil are screened by arranging an L-shaped rod 7 that moves up and down alternately at intervals instead of the sieve, and the up and down movement of the L-shaped rod 7 is more efficient, which greatly improves the screening efficiency, can not only screen out large particles of impurities, but also avoid the problem of the sieve holes being blocked by the soil, reducing the difficulty of subsequent manual cleaning; by matching the U-shaped rod 23 and the pin shaft 22 with the pin shaft holes 21 at different heights, it can be suitable for walking equipment at different heights, and can turn and improve the soil of different depths as needed, greatly improving practicality.
