Description

Technical Field

[0001] The utility model belongs to the technical field of agricultural machinery, and in particular relates to a leg structure for agricultural machinery. Background Art

[0002] Agricultural machinery refers to various machines used in the process of crop planting and animal husbandry production, as well as in the primary processing and handling of agricultural and livestock products. When in use, agricultural machinery is generally equipped with support legs to support the agricultural machinery and facilitate its placement and use.

[0003] In a Chinese patent with publication number CN212361302U, a support leg for agricultural machinery is disclosed. The support leg for agricultural machinery can rotate a push column according to an uneven placement surface to drive the connecting stud to rotate, so that its supporting chassis can move up and down by utilizing the thread performance between the connecting stud and the connecting screw hole to push the agricultural machinery so that the agricultural machinery can be pushed to a horizontal angle for placement and support, thereby achieving the benefit of being easy to place on an uneven placement surface; however, when the above-mentioned support leg for agricultural machinery is actually used, the height of the support leg body is generally adjusted by rotating the connecting stud. However, when the support leg body is used for the agricultural machinery, it is difficult to effectively limit the connecting stud, so that the connecting stud is easy to rotate when the agricultural machinery is in use, thereby causing the support leg body to shake, causing its height to change, affecting the stability of the agricultural machinery when in use.

[0004] In order to solve the above problems, the present application proposes a leg structure for agricultural machinery. Utility Model Content
