Abstract：To increase the efficiency of large area spraying pesticide to kill locust, the electrostatic spray theory is applied on the machine design. This machine has been applied to the work of killing locust in Xinjiang province, and has achieved great effect. 4WD cross-country vehicle was used as carrier, and many components were installed on it. Spraying and movement of spray bucket can be controlled in vehicle cab. The main components of this machine and their functions are stated, which include transmission system, spray fan bucket, spray bucket rotary part and brake part. Design and analysis are focused on spray fan bucket and spray bucket rotary part which consist of electromotive handspike, spherical bearing, platform of rotary part, pinwheel reducer, electromagnetic braking controller, machine frame and so on. Calculation method of working stroke of electromotive handspike is deduced. Structure design and movement analysis of electromagnetic braking controller are indicated.
