Electric sprayers are often used in agricultural farming and in greenhouses. This electric sprayer directly replaces manual ones, which saves a lot of manpower. For larger areas, electric sprayers can Spraying quickly. At the end of a control cycle or when it is used again every few days, the dry battery should be taken out to prevent the battery from rusting. The impeller is one of the most critical parts in the electric pressure washer, which directly affects the spray quality. The impeller consists of a front impeller and a rear impeller. The front and rear impellers are connected by eight fixing pins. On the rear impeller, each pin hole has a 1.5 mm thick shoulder on both sides to ensure a certain distance between the front and rear impellers. After the front and rear impellers are installed, press one end of the micro motor shaft so that the impeller rotates.
The front and rear impellers are disc-shaped, mainly to prevent the drops of the drug adhering to the surface of the impeller from falling or directly smashing, causing phytotoxicity. In order to make the atomized fog point more uniform, 36 is engraved on the outer edge of the two impellers. The semi-conical small teeth are used to reduce the adhesion of the film attached to the surface of the impeller, and become the starting point of the fog point at the time of the separation, so that the liquid regularly draws a strip of liquid along it.
One end of the liquid-proof sleeve is a hole with a diameter of 7 mm, and the front end of the impeller shaft is tightly closed; the other end is extended into the groove of the end of the motor casing to prevent the motor shaft from being exposed to the rust of the liquid. The liquid-proof sleeve rotates with the impeller at a high speed. The liquid splashed on it is thrown out to prevent the liquid from infiltrating the inside of the motor and causing corrosion. Grease can also be applied to the liquid-proof sleeve to increase bearing lubrication and improve motor life.
The pressure sprayer is in the shape of a national column, and the sleeve is placed inside the tube. A medicine bottle holder is installed in the upper fork. There are two round holes with a diameter of 4 mm on the lower side of the fork, which cooperate with the five semi-circular grooves on the shoulder of the vial holder, so that the nozzle body has five different rotation angles, which can be adjusted according to the operation requirements. A circular hole having a diameter of 3.2 mm is provided in the fork for the purpose of threading.
