[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 of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Embodiment 1

[0020] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: a soil-turning device with adjustable depth, including a spade handle 1. One end of the spade handle 1 is fixedly connected with a handle 11. An operator can apply force downward on the spade plate 5 by holding the handle 11. The end of the spade handle 1 is fixedly connected with a housing 2. The housing 2 wraps the fixing plate 4 inside. At the same time, a clamping block 21 is fixedly connected to the inner wall of the housing 2. The clamping block 21 is fixedly connected to both sides of the inner wall of the housing 2 to ensure that the fixing plate 4 slides in a straight line during the sliding process. A threaded ring 3 is connected to the surface of the spade handle 1. The inner wall of the threaded ring 3 is slidably connected to the surface of the spade handle 1. At the same time, a notch is opened at one end of the threaded ring 3, so that the size of the threaded ring 3 has a certain elasticity and can be fastened on the surface of the spade handle 1. One end of the threaded ring 3 is fixedly connected with a connecting plate 31. Both ends of the connecting plate 31 are respectively fixedly connected to the surface of the clamping plate 41. A clamping ring 32 is arranged on the surface of the threaded ring 3. A threaded groove is opened inside the clamping ring 32, and the threaded groove opened inside the clamping ring 32 is adapted to the thread on the surface of the threaded ring 3. The clamping ring 32 controls the tightness between the inner wall of the threaded ring 3 and the surface of the spade handle 1.

[0021] Embodiment 2

[0022] As Figures 1-4 shown in the figure, one end of the clamping block 21 is connected with a fixing plate 4. A sliding groove is opened on the surface of the fixing plate 4, and the sliding groove opened on the surface of the fixing plate 4 is adapted to the surface profile of the clamping block 21, so that the fixing plate 4 can slide back and forth on the surface of the clamping block 21. One end of the fixing plate 4 is fixedly connected with a clamping plate 41. The clamping teeth opened on one side of the clamping plate 41 are meshed with the clamping teeth on the surface of the gear 7. A spade plate 5 is fixedly connected to the surface of the fixing plate 4. One end of the spade plate 5 extends beyond the bottom end of the housing 2. The bottom end of the fixed column 6 is fixedly connected to the inner surface of the housing 2. One end of the fixed column 6 is connected with a limiting plate 61. The size of the limiting plate 61 is larger than the notch between the gear 7 and the fixed column 6. At the same time, the gear 7 is rotatably connected to the surface of the fixed column 6. When the clamping plate 41 moves up and down, the clamping teeth at the edge of the clamping plate 41 drive the gear 7 to rotate on the surface of the fixed column 6, and the two gears 7 rotate towards each other to adjust the length of the spade plate 5.

[0023] Working principle:

[0024] As Figures 1-4As shown in the figure, by designing structures such as the clamping plate 41 and the gear 7, the snap ring 32 is rotated counterclockwise to loosen the inner wall of the threaded ring 3 from the surface of the spade handle 1. Then, the threaded ring 3 slides downward on the surface of the spade handle 1, and the fixing plate 4 slides downward along the surface of the clamping block 21. At the same time, the teeth on the edge of the clamping plate 41 drive the gear 7 to rotate on the surface of the fixed column 6, and the spade plate 5 moves downward following the sliding of the fixing plate 4 until the length of the spade plate 5 exposed at the bottom of the housing 2 meets the depth of the soil for crop sowing. Finally, the inside of the snap ring 32 is nested on the surface of the threaded ring 3, and the snap ring 32 is rotated clockwise to tightly fix the inner wall of the threaded ring 3 to the surface of the spade handle 1, preventing the threaded ring 3 from sliding and moving along the surface of the spade handle 1.

[0025] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
