At this time, it is necessary to stop the machine for operation. However, during this process, the operator directly replaces the tilling knife on the rotating shaft. If someone accidentally touches the operation switch, it is easy to accidentally start the micro-tiller. At this time, for the maintenance staff, the high-speed rotating tilling knife will cause casualties. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1 to 4, in the embodiment of the present utility model, a soil-turning device for agricultural machinery planting includes a hand-held support 1, a diesel engine 2 is installed on the hand-held support 1, and traveling wheels 3 are rotatably installed at the bottom end of the hand-held support 1. The output end of the diesel engine 2 is connected to a rotating shaft 4. A sliding mechanism is arranged on the inner wall of the rotating shaft 4, and a soil-turning mechanism is fixedly connected to the sliding mechanism. Both ends of the rotating shaft 4 are detachably connected with a pressing mechanism for pressing the sliding mechanism; the sliding mechanism includes a sliding groove 12 opened inside the rotating shaft 4, one end of the sliding groove 12 penetrates to the outside of the rotating shaft 4, and a sliding block 6 is slidably connected to the inner wall of the sliding groove 12. The narrow end of the sliding block 6 penetrates to the outside of the rotating shaft 4.

[0020] In this embodiment: when using this device, first push the hand-held support 1, the hand-held support 1 drives the traveling wheels 3 to slide on the ground, and at the same time start the diesel engine 2. When the diesel engine 2 works, it drives the shaft to rotate. Through gear transmission, the torque is transmitted to the rotating shaft 4. When the rotating shaft 4 rotates, it drives the sliding mechanism, the soil-turning mechanism and the pressing mechanism to rotate synchronously. At this time, the soil-turning mechanism is in full contact with the cultivated soil, and the high-speed rotating soil-turning mechanism breaks and turns the soil.

[0021] Please refer specifically to Figure 2 and Figure 3 , the soil-turning mechanism includes a connecting plate 8 fixedly connected to the outside of the sliding block 6 and slidably connected to the outer wall of the rotating shaft 4, and a tillage knife 9 is detachably connected to the connecting plate 8.

[0022] In this embodiment: when the rotating shaft 4 rotates, it drives the connecting plate 8 to rotate at a high speed, and the connecting plate 8 drives the tillage knife 9 thereon to rotate at a high speed, thereby realizing the breaking and turning of the soil.

[0023] Please refer specifically to Figure 3 and Figure 4 , the pressing mechanism includes screw holes 13 opened at both ends of the rotating shaft 4, a locking stud 11 is threadedly connected to the inner wall of the screw holes 13, a pressing plate 5 is integrally formed at one end of the locking stud 11, the diameter of the pressing plate 5 is larger than the diameter of the rotating shaft 4, and a hexagon groove 10 recessed inward is integrally formed at one end of the pressing plate 5 away from the rotating shaft 4.

[0024] In this embodiment, when the tillage knife 9 needs to be replaced due to wear, a hexagonal wrench is used to dock with the hexagonal groove 10 at this time, and the pressure plate 5 is driven to rotate by the hexagonal wrench. The pressure plate 5 drives the locking stud 11 to rotate until the locking stud 11 is completely separated from the screw hole 13. At this time, the sliding mechanism can be pulled to completely separate the two parts of the sliding mechanism, and then multiple connecting plates 8 and the tillage knife 9 on the connecting plate 8 can be disassembled. After that, the damaged tillage knife 9 can be disassembled and replaced separately. In this way, during the process of replacing the tillage knife 9, it can be avoided that the diesel engine 2 is started by accidental touch, resulting in the rotation of the tillage knife 9 and causing accidental injuries.

[0025] Please refer specifically to Figure 4 , a limiting protrusion 7 protruding outward is integrally formed on the outer periphery of the rotating shaft 4, and one end of the sliding block 6 in the pressed state is in close contact with both ends of the limiting protrusion 7.

[0026] In this embodiment, after replacing the outer wall of the damaged tillage knife 9, the sliding block 6 is inserted into the sliding groove 12, and then the locking stud 11 is re-threaded into the screw hole 13 until the locking stud 11 is completely tightened. At this time, the pressure plate 5 limits one end of the sliding block 6, and the other end of the sliding block 6 abuts against the end of the limiting protrusion 7. At this time, the installation of the tillage knife 9 can be completed.

[0027] Please refer specifically to Figure 4 , the cross-sectional areas of both ends of the limiting protrusion 7 are equal to the cross-sectional area of the sliding block 6 outside the rotating shaft 4.

[0028] In this embodiment, the limiting protrusion 7 and the pressure plate 5 cooperate to limit the sliding block 6 to prevent it from sliding during rotation.

[0029] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
