Backpack high-pressure electric sprayer

Abstract

A backpack high pressure power sprayer comprises a base, an electrical pump component installed in the base and a storage battery; wherein, the electrical pump component is a membrane pump driven by a DC electric machine, a water inlet pipe of the membrane pump is connected with a water tank, and a water outlet thereof is connected with a spray rod by a water outlet pipe; the water tank is installed on the base, a liquid feeding hole is opened on the top of the water tank and is provided with a cover, and a strap is arranged on the wall of the water tank; the backpack high pressure power sprayer is characterized in that the base is internally provided with a support pillar, the top surface of the support pillar is contacted with the bottom surface of the water tank and is higher than the mounting planes of the storage battery and the membrane pump, a left side plate of the base is equipped and connected with a speed control switch of the storage battery, a fuse, a power switch and a charging socket, and a right side plate of the base is provided with a mounting groove which is internally provided with a water outlet connector of the membrane pump, so that the assembly and disassembly, the maintenance and the operation are considerably convenient.

Description

technical field [0001] The invention relates to a sprayer, in particular to a backpack-type high-voltage electric sprayer, which belongs to agricultural plant protection machinery, and is mainly used for preventing and controlling diseases and insect pests in agriculture, and can also be used for spraying liquid medicine during sanitation and epidemic prevention. Background technique [0002] The sprayer belongs to a kind of commonly used agricultural plant protection machinery, which is used to prevent and control plant diseases and insect pests of crops, and can also be used for epidemic prevention and disinfection in hygiene. Existing sprayers can be divided into manual and electric. At present, knapsack sprayers are mostly manual. Manual knapsack sprayers are labor-intensive because one hand operates the spray gun, while the other hand constantly shakes the pressure pump rocker. Therefore developed the electric sprayer that adopts storage battery power supply in recent y...

AI Technical Summary

Problems solved by technology

Therefore developed the electric sprayer that adopts storage battery power supply in recent years, but there is following shortcoming in existing electric sprayer: the first, in order to make water tank not damage the motor and the pump that are installed in the base, usually make a supporting water tank on the base top The motor and pump are installed below the plane, and a cover plate is made to seal the base (in order not to expose the motor and pump to the outside), which makes assembly and maintenance quite troublesome; second, a spray boom only has One nozzle, the working efficiency is low; third, the nozzle is easy to block, thus damaging the motor and pump
