Experimental Study of Intelligent Precision Cotton Topping Machine

[摘要] Existing problems in operation of cotton topping machines include poor performance in actual height measurement of the cotton plant, omission of topping, severe over topping, low level of intelligence, and etc. To solve these problems, a scheme of separating the detection device from the topping device and separating the lifting drive from the topping drive is proposed herein, and an intelligent precision cotton topping machine is designed based on the Field-Programmable Gate Array (FPGA) technology. During the topping practice, the detection device precisely detects the height of the cotton plant, while the topping device controlled by the control system carries out accurate quantitative topping. The touch screen control system, which displays the operating speed, work area in real time and monitors the process of cotton topping, significantly increases the level of intelligence. Field tests show that the whole structure of the machine is stable, the machine operation speed is within 3.24km•h-1, the topping rate is about 90%, and the topping quantity is close to the set value, so it is possible to realize quantitative topping and this research provides technical support for cotton topping mechanization.
