A self-propelled sprayer is a device for dispersing liquids and is a pesticide spraying machine. It is divided into agricultural, medical, and other uses (such as industrial use). Agriculture is classified as plant protection machinery in agricultural machinery. Usually, it is called human driven spray and power driven spray (engine, motor). According to the working principle, agricultural spray can be divided into hydraulic spray, pneumatic spray and centrifugal spray. According to the mode of carrying, it can be divided into handheld, backpack, shoulder mounted, pedal, stretcher, trolley, self-propelled, vehicle mounted, suspended, and aviation spray.

Self-propelled sprayer

1. Ultrasonic atomization. Vibration generates "waves" on the water surface. The vibration frequency of ultrasound is very high, so its "wave" wavelength is very small, so its "wave" - small water droplets are also very small, and these small water droplets become fog. The throat spray used in hospitals to treat respiratory diseases is ultrasonic atomization.

2. The water pressure is put into the thin pipe to cause high-speed water flow, and the high-speed water flow of agricultural spray will break into small drops when encountering obstacles. It's like turning a faucet with your finger and plugging it. Most household agricultural spray adopt this structure, which has low cost.

3. Charge water (water is a dielectric) and use the same type of charge to repel each other, dividing water into droplets. The droplet size of this method is very small. The same principle applies to car painting.

4. Adopting Bernoulli's principle. Bernoulli's principle states that in the same fluid, high velocity results in low pressure; Low flow rate and high pressure. The fluid will automatically flow from high pressure to low pressure. When passing through a bifurcated pipe, low-speed water flows towards high-speed airflow. Water is torn into small droplets by high-speed air (imagine that the water flowing out of the faucet is initially slow, it is a column of water, but gradually increases in speed and becomes droplets), and these small droplets become fog when sprayed out.

The main functions and characteristics of the self-propelled spraying machine are as follows:

1. Automatic return function

When it moves forward to the endpoint position, it can automatically return. After starting from the starting point and reaching the end point, the sprinkler can automatically return to the starting point and stop. Set the starting and ending points at will. The start and stop of the self-propelled spraying machine are controlled by a magnetic induction model. As long as the starting and stopping magnets are moved, the operating stroke of the sprayer can be changed.

2. Stepless speed regulation

The bidirectional running speed of the nozzle can be arbitrarily set within 4-16m/min. Setting an appropriate operating speed can greatly improve irrigation efficiency, which can provide different crops in the greenhouse with their own water and fertilizer needs.

3. Regular spraying

Set the spraying cycle time, and the nozzle can automatically spray regularly.

4. With remote control function

This feature greatly saves labor costs. Through remote control, one operator can operate multiple sprinkler heads simultaneously.
