Apical dominance of cotton plants can be eliminated effective to achieve the objective of accurate topping, so that operating efficiency and operating quality are improved. The intelligent accurate cotton topping device comprises a rack, a profiling mechanism, a topping mechanism, a height adjusting mechanism and a controlling mechanism, the rack is connected on an operating machine in a hung manner, the profiling mechanism comprises a profiling contact plate and an angle sensor, the topping mechanism comprises a sliding seat, a power mechanism mounted on the sliding seat, a knife shaft connected with the power mechanism, a knife disc fixed on the knife shaft, and a displacement sensor mounted on the sliding seat, the height adjusting mechanism is fixed on the rack and connected with the sliding seat to drive the sliding seat to move up and down relatively to the rack, and the controlling mechanism is arranged on the rack and connected with the angle sensor, the displacement sensor and a speed sensor.

Description

Technical field [0001] The invention relates to an agricultural mechanical device, in particular to an intelligent and precise cotton topping device and a multi-row cotton topping machine composed of it. Background technique [0002] Cotton is a labor-intensive cultivated crop with complicated planting management. In the entire production process, except for the topping and harvesting links, the whole process has been basically mechanized. Cotton topping has problems such as tight time, heavy tasks, and high labor intensity. The existing mechanized cotton topping cannot meet the requirements of ordinary cotton planting users, which affects the popularization of mechanized topping technology. [0003] In recent years, foreign countries have mainly used chemical control technology to control the growth trend of cotton. At present, the experimental research on cotton topping in China is mainly concentrated in the two fields of chemical control and topping. Chemical control technology...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems of poor profiling effect and low topping precision of the existing cotton topping machinery, the present invention provides an intelligent and precise cotton topping device and a multi-row cotton topping machine, which can complete the high profiling of cotton plants at one time, and accurately The topping operation can effectively eliminate the advantage of the top of the cotton plant and achieve the purpose of precise topping. At the same time, it reduces the labor intensity of people, improves the operation efficiency and quality, and most importantly, increases the yield per mu.
