Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, and in particular relates to a peanut hilling machine with adjustable depth. Background Technology

[0002] Hilling is one of the key aspects of increasing yield in peanut cultivation. Hilling can effectively promote peanut pegging, improve soil permeability, suppress weed growth, and resist drought and flood disasters.

[0003] Currently, peanut ridging machines commonly used in agricultural production mainly consist of components such as a frame, power unit, crushing wheel, and soil turning plate. They achieve soil ridging, soil breaking, and shaping of peanut ridges through mechanical operations.

[0004] The existing hilling machines mostly adopt a fixed hilling depth design, which makes it difficult to flexibly adjust the depth according to the soil and peanut growth stage. Moreover, the crushing wheel and turning plate are usually fixed to the frame with bolts, and their positions cannot be adjusted. This will cause the soil to be pushed to the side of the ridge during the hilling process to be unevenly distributed, resulting in inconsistent soil coverage on both sides. Excessive soil turning on one side will bury the peanut seedlings, while the other side will not be covered with enough soil. Summary of the Invention

[0005] The purpose of this utility model is to provide an adjustable-depth peanut hilling machine, which solves the problems of existing peanut hilling machines that cannot flexibly adjust the hilling depth and cannot evenly cover the soil during use, through the cooperation of the adjustment mechanism and the moving mechanism.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
