With the continuous development of modern agricultural technology, agricultural machinery and equipment play an increasingly important role in agricultural production. Among them, the self-propelled pesticide applicator has become an indispensable part of modern agricultural production due to its high efficiency, convenience, and environmental protection. This article will provide a detailed introduction to the structure, working principle, advantages, and future development trends of self-propelled sprayers.

1、 Structural composition

The self-propelled pesticide applicator mainly consists of the following parts:

Walking system: including driving wheels, steering wheels, transmission devices, etc., allowing the pesticide applicator to freely walk on the field.

Liquid medicine tank: used to store liquid medicine, usually made of corrosion-resistant and easy to clean materials, and the capacity can be adjusted according to actual needs.

Liquid medicine pump: responsible for sucking the liquid medicine out of the liquid medicine tank and delivering it to the nozzle for spraying through a pipeline.

Spray head system: composed of multiple spray heads, the angle and amount of spray can be adjusted according to the type and growth of crops, ensuring that the medicine is evenly sprayed on the crops.

Control system: including electrical control system and hydraulic control system, used to control the movement, steering, opening and closing of the dispensing machine, and other actions of the medication pump.

2、 Working principle

The working principle of a self-propelled pesticide applicator is relatively simple. When the pesticide spraying machine is started, the walking system starts to work, driving the pesticide spraying machine to walk in the field. At the same time, the medication pump starts to operate, sucking the medication out of the medication tank and delivering it to the nozzle through a pipeline. The nozzle sprays according to the set angle and spraying amount to evenly cover the crop with the medicine. During the spraying process, the control system can adjust parameters such as walking speed, steering angle, and the opening and closing of the liquid pump as needed to meet the spraying needs of different crops.
