[0002] As one of the most important agricultural products in my country, cotton needs to be toppled during the cotton planting process. Cotton topping is to eliminate the apical growth advantage of cotton by topping the top of the cotton plant, regulate the transportation direction of nutrients such as water and inorganic salts in the cotton body, so as to promote the development of cotton reproductive organs, reduce the waste of water and fertilizer by ineffective branches and leaves, promote early and more bolls of cotton plants, and less boll shedding, thereby improving the yield and quality of cotton.

[0003] The existing cotton topping mechanism and the three-point suspension of the traction device are usually directly hinged by a latch, and the traction device is driven to move the three-point suspension and the cotton topping mechanism, so that the cotton topping mechanism performs topping work.

When passing through a slope, the cotton topping mechanism cannot move up and down with the terrain level, and the safe ground clearance cannot be guaranteed, which may cause safety accidents. At the same time, the tilted cotton topping mechanism will also affect the normal operation of the internal topping mechanism. For this reason, we propose a cotton topping machine.
