Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and in particular relates to an angle adjustment device used on a reversible plow for adjusting the included angle between a plow body assembly and a reversible plow main beam. The adjustment device can adjust the included angle between the plow body assembly and the reversible plow main beam. Background Art

The characteristic of the reversible plow is that each plowshare adopts a set of left-right symmetrical plow bodies, which can be turned 180 degrees through the reversing mechanism. The left and right plow bodies can both operate after rotation without changing the direction of turning the soil.

[0003] The flip plow at least includes a traction frame assembly, a main beam, a depth-limiting wheel assembly, and a plow body assembly (wrapped with 4 plywood plates, a plow column and a plowshare). During the flipping operation, the forward and reverse plow bodies on the plow frame are driven to perform vertical flipping movements through the extension and retraction of the flip cylinder, and are alternately changed to the working position.

[0004] For different plots of land, the working angle of the plow body needs to be adjusted according to actual use needs by adjusting the connection anchor point between the plow clamp and the main beam, that is, a plurality of bolt holes are provided on the main beam, and a plurality of bolt holes are also provided on the plow clamp. By adjusting the corresponding relationship between different bolt holes, the working angle of the plow body is determined. After the bolt holes correspond to each other, they are connected using connecting bolts. This approach requires preset bolt holes on the main beam, and the plow body can only be fixed at the preset position during use. The flip plows disclosed in CN304898974 and CN113330830 all have the above problems.
