[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] Reference Figure 1 - Figure, a soil improvement and turning device, including a tractor 2, a turning assembly 1 is arranged at the rear of the tractor 2 in the direction of travel, the turning assembly 1 includes a rear frame 5, a moldboard 6 and a crushing grid 7 are arranged at the bottom of the rear frame 5, the moldboard 6 is arranged on the side adjacent to the tractor 2, and a crushing roller 8 is arranged above the crushing grid 7, and the crushing roller 8 is driven by a drive motor 4, and the drive motor 4 is fixedly connected to the rear frame 5.

[0022] The soil turning component 1 is arranged behind the tractor 2 to prevent the tractor 2 from affecting the plowed ground. The moldboard 6 shovels up the soil and forms bulges between adjacent moldboards 6. The bulges will have soil clods. After the crushing grid 7 takes over the soil clods, the smaller soil clods (smaller than the grid gap) will not affect the planting and will fall up and down on the grid. The larger soil clods will be crushed by the crushing roller 8 and fall through the grid gap, thereby preventing a large amount of soil from clumping.

[0023] In order to ensure the crushing effect, two groups of crushing rollers 8 are set. The crushing rollers 8 on the side close to the tractor 2 are higher than the crushing rollers 8 on the side away from the tractor 2. The rotation direction of the crushing rollers 8 is the same as the rotation direction of the tractor 2 wheels, and the surface is provided with evenly distributed protrusions to improve the ability to grab soil blocks.

[0024] In another preferred embodiment, a lifting frame is fixedly connected to the bottom of the rear frame 5 near the tractor 2, a support rod is fixedly connected to the bottom of the lifting frame, and the moldboard 6 is fixedly connected to the bottom of the support rod. Through the arrangement of this structure, the height of the moldboard 6 can be appropriately adjusted according to the actual use requirements of the plow trough.

[0025] In other preferred embodiments, a positioning bin and a transmission bin are provided at the bottom of the rear frame 5 away from the tractor 2, and the crushing roller 8 is rotatably connected between the positioning bin and the transmission bin. A transmission assembly is provided in the transmission bin, and the transmission assembly is used to transmit the power of the drive motor 4 to the crushing roller 8.

[0026] In other preferred embodiments, a pressure roller 3 is provided at the front side of the tractor 2. By providing the pressure roller 3, the soil in front of the tractor 2 is first flattened to ensure uniformity when plowing with the moldboard 6 at different positions.

[0027] There are two ways to set the crushing grid 7, namely:

[0028] (1) The moldboard 6 is tilted, with its rear end higher than its front end. The crushing grid 7 is horizontally arranged, with its height lower than the rear end of the moldboard 6 and higher than the front end.

[0029] (2) The moldboard 6 is tilted, with its front end higher than its rear end. The crushing grid 7 is tilted, with its front end higher than its rear end. The front end of the crushing grid 7 is lower than the rear end of the moldboard 6, and the rear end of the crushing grid 7 is higher than the front end of the moldboard 6. This structure allows larger clods to roll behind the crushing grid 7, ensuring the effectiveness of the crushing rollers 8.

[0030] In other preferred embodiments, the crushing grid 7 is connected to the rear frame 5 via positioning frames 9. Two sets of positioning frames 9 are provided: the front positioning frames 9 are fixed and hinged to the crushing grid 7, and the rear positioning frames 9 are retractable and hinged to the crushing grid 7. This structure allows the inclination angle of the crushing grid 7 to be controlled, and the tillage trough can be covered with soil when necessary.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
