An agriculture sprayer refers to a device that sprays a spray of fine spray and is a kind of pesticide application machinery. It is composed of compressed air devices, thin tubes, nozzles, and so on. In agriculture, agriculture sprayers are indispensable and important agricultural tools for the prevention and control of pests and diseases. Next, let us know about the operation information of agriculture sprayers. Here are some answers.

Operation points.
First, the pesticide and water must be formulated into a liquid medicine according to the specified ratio and then poured into the medicine bucket of the agriculture sprayer, and then the medicine liquid bucket is carried on the shoulders and enters the work area. When working, the left-hand grips the hand lever of the agriculture sprayer to reciprocate up and down. When the liquid medicine in the barrel reaches a certain pressure, the liquid medicine switch is turned on. At this time, the prepared liquid medicine can be sprayed from the spray head. Hold the spray rod with your right hand and swing it forward and right, and spray it forward while walking. The liquid medicine will be sprayed on the leaves, stems, and roots of the crops.
Principle of operation.
The principle of agriculture sprayer spraying can be divided into four types. The first is Bernoulli's principle. Bernoulli's principle says that in fluids when the velocity of the fluid is high, the pressure is small; and vice versa. Normally, fluid will flow spontaneously from high pressure to low pressure. For example, the water flowing out of the faucet is slow at first, which is a water column. But then the speed gradually increased and it became drop by drop. After that, it sprayed out and turned into fog. The second is the principle that the high-speed water flow breaks into small water droplets when it hits an obstacle. It is to press water into a thin tube to cause a high-speed water flow, and the high-speed water flow breaks into small water droplets when it hits an obstacle. Household agriculture sprayers often use this structure, and the cost is low. The third is the principle of centrifugal force. It is a high-speed rotating atomization disk that uses centrifugal force to throw the liquid out to form small droplets, similar to the situation when an umbrella rotates. The fourth is the principle of ultrasonic atomization. Vibration can cause waves on the water surface. The frequency of ultrasonic vibration is very high, and the wavelength of its waves is very small, so its small water droplets are also very small, and these small water droplets become fog.
