Description

Technical Field

[0001] The utility model relates to the field of agricultural machinery, in particular to a reset buffer device for agricultural machinery. Background Technique

[0002] Agricultural machinery refers to various machinery used in the process of crop planting. The soil-turning machine and the seeding machine are both parts of agricultural machinery. For example, a soil-turning machine is needed to turn the soil before planting crops.

[0003] At present, agricultural machinery is usually connected to a tractor by a pull rod, which can support the agricultural machinery. However, the current pull rod assembly does not have a structure for buffering the agricultural machinery. When the tractor drives the agricultural machinery on a bumpy road, it is easy to damage the hydraulic transmission systems of the agricultural machinery and the tractor, thereby affecting the service life. Therefore, we propose a reset buffer device for agricultural machinery to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a reset buffer device for agricultural machinery to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:
