Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery, specifically to a soil covering device with a soil volume adjustment mechanism. Background Technology

[0002] In existing technology, the soil discharge volume is controlled by adjusting the size of the discharge opening on the soil covering device using an adjusting plate. However, the current adjusting plate is welded to a cylindrical connecting shaft, and the discharge opening is adjusted by rotating the connecting shaft through an external device. This approach has several drawbacks: First, the cylindrical connecting shaft cannot be conventionally fixed to the adjusting plate; it can only be fixed by welding. However, welding can only be done after the adjusting plate and connecting shaft are installed, requiring welding inside the device, which is cumbersome, time-consuming, and labor-intensive. Second, the welded adjusting plate and connecting shaft cannot be directly removed; removal requires destructive damage to the connecting shaft and adjusting plate, making subsequent maintenance difficult. Once damaged, both the connecting shaft and adjusting plate must be completely destroyed and replaced, increasing production costs.

[0003] Therefore, it is necessary to provide a new technical solution. Utility Model Content

[0026] This utility model provides a soil covering device with a soil volume adjustment mechanism, see reference. Figures 1 to 3 It includes a casing 1, a conveyor belt 2, and a soil volume adjustment mechanism 3.

[0027] The housing 1 includes side plates 11 on both sides and a main plate 12 in the middle. The conveyor belt 2 is located below the main plate 12 and has an opening between it and the main plate 12. The soil adjustment mechanism 3 includes a rotating shaft 31, a connecting plate 32 and a baffle 33. The two ends of the rotating shaft 31 are pivotally connected to the side plates 11 respectively. The first end of the connecting plate 32 is fixed to the rotating shaft 31, and the second end of the connecting plate 32 is fixed to the baffle 33. The baffle 33 is located at the opening, and the gap between the baffle 33 and the opening changes as the rotating shaft 31 rotates.

[0028] Furthermore, the surface of the rotating shaft 31 includes at least one edge along the axial direction, and the connecting plate 32 is provided with a through hole with the same cross-sectional shape as the rotating shaft 31. The connecting plate 32 is sleeved on the rotating shaft 31 through the through hole.

[0029] Furthermore, the connecting plate 32 comprises two plates, each located on the rotating shaft 31 near the side plate 11.

[0030] Furthermore, the cross-sectional shape of the rotating shaft 31 is a regular hexagon.

[0031] Furthermore, the baffle 33 includes a first connecting portion 331 perpendicular to the connecting plate, a second connecting portion 332 disposed above the first connecting portion 331, and a third connecting portion 333 disposed below the first connecting portion 331.

The first end of the handle 34 is fixedly connected to the end of the rotating shaft 31 that extends out of the side plate 11. The second end of the handle 34 is engaged in the slot 35 via a knob. The slot 35 has an arc-shaped structure and is fixed to the outside of the side plate 35, with the connecting shaft 31 as its center. Rotating the handle 34 along the slot 35 adjusts the gap between the baffle 33 and the opening.

[0033] The working principle of this utility model is as follows: a hexagonal connecting shaft is used instead of the original cylindrical connecting shaft, which eliminates the need for welding and fixing with the connecting plate. The hexagonal connecting shaft directly drives the connecting plate to rotate with it due to its angular structure, which facilitates disassembly, assembly, and subsequent maintenance.
