[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0034] Please see Figures 1-5 This utility model provides a technical solution for a soil-turning device for rice planting: including a frame 1, a handle 2, wheels 3, a leveling scraper 4, a crushing plate 5, an adjusting frame 6, a first motor 7, a second motor 8, a connecting shaft 9, a soil-turning blade 10, a mounting block 11, a crushing block 12, a toothed block 13, a limiting slide bar 14, a limiting groove 15, a mounting bracket 16, a worm gear 17, a worm wheel 18, and a heat dissipation cover 19.

[0035] The working principle and usage process of this utility model: First, hold the handle 2 and push the frame 1 into the paddy field through the wheel 3. Turn on the power switch of the second motor 8. The heat dissipation cover 19 has a hollow structure, which facilitates heat dissipation protection for the second motor 8 and the first motor 7, and also facilitates sun protection and waterproofing.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, the soil-turning blades 10 are evenly spaced on the outer surface of the connecting shaft 9, and the soil-turning blades 10 are connected to the connecting shaft 9 by bolts to form a detachable structure. The middle part of the connecting shaft 9 is integrally fixedly connected to a worm wheel 18, and the right side of the worm wheel 18 is meshed with a worm 17. The worm 17 is rotatably connected to the mounting bracket 16, and the worm wheel 18, the worm 17 and the soil-turning blades 10 form a linkage mechanism. The mounting bracket 16 has an "F" shaped structure, and the upper end of the mounting bracket 16 is fixedly connected to the lower end face of the frame 1 by bolts. The meshing of the worm 17 and the worm wheel 18 drives the worm wheel 18 to rotate. The worm wheel 18 drives the soil-turning blades 10 to rotate counterclockwise through the connecting shaft 9. The frame 1 is pushed to the left, which makes it easier for the blades of the soil-turning blades 10 to insert into the soil. When the soil-turning blades 10 rotate, they turn the soil over, which facilitates quick soil turning.

[0037] Combination Figure 1 , Figure 2 and Figure 4As shown, the adjusting frame 6 and the breaking plate 5 form a "T"-shaped structure. Limiting slide rods 14 are integrally welded to both the left and right side walls of the adjusting frame 6. The limiting slide rods 14 have a vertically placed "U"-shaped structure and slide on the side wall of the limiting slot 15. The limiting slot 15 is located on the lower left side of the frame 1, and the left side of the frame 1 is hollow. A toothed block 13 is meshed inside the adjusting frame 6. The rear central shaft of the toothed block 13 is fixedly installed to the output end of the first motor 7. Half of the outer surface of the toothed block 13 has a serrated structure. The adjusting frame 6 forms a lifting structure on the frame 1 through the toothed block 13. The height dimension of the lifting trajectory of the section frame 6 is not greater than the height dimension of the limit slide bar 14. The crushing block 12 has a triangular pyramid structure and is arranged in an array at the lower end of the crushing plate 5. The crushing plate 5 forms a lifting structure at the lower end of the frame 1 through the adjusting frame 6. When the power switch of the first motor 7 and the second motor 8 are turned on at the same time, the first motor 7 drives the toothed block 13 to rotate inside the frame 1. The toothed block 13 meshes with the adjusting frame 6. The toothed block 13 has a half gear structure, which facilitates the adjustment frame 6 to move up and down, and thus facilitates the crushing plate 5 to crush the soil up and down, making it easy to crush large soil blocks into small fragments for convenient use.

[0038] Combination Figure 1 , Figure 2 and Figure 5 As shown, the longitudinal section of the leveling scraper 4 is semi-circular, and the leveling scraper 4 is evenly spaced at the lower end of the mounting block 11. The mounting block 11 is connected to the frame 1 by a snap-fit ​​connection. When the frame 1 moves to the left, the leveling scraper 4 scrapes and flattens the broken soil clods, which makes it easier to maintain the flat state of the paddy field and facilitates the later planting of rice. This is the working process of the soil turning device for rice planting.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
