Two-way hydraulic putty sprayer

Abstract

The invention relates to a two-way hydraulic putty spraying machine in the field of construction machinery and equipment, which includes a motor, an oil pump, an oil tank, a two-way hydraulic transformer, a linkage electromagnetic plunger high-pressure one-way valve, an electromagnetic steering, a positioning switch, a medium discharge port and a medium filter. The two-way hydraulic transformer includes a main cylinder, a main piston, a first auxiliary cylinder, a first auxiliary plunger, a second auxiliary cylinder, a second auxiliary plunger, and a plunger connecting shaft, wherein the cross-sectional area of ​​the main piston is the first The multiple of the cross-sectional area of ​​the auxiliary plunger is also several times of the cross-sectional area of ​​the second auxiliary plunger. The linked electromagnetic plunger high-pressure one-way valve includes a seat body, an electromagnet part, a first buffer part, a second buffer part, a first valve body and a second valve body respectively located on the left and right sides of the electromagnet part. The two-way hydraulic putty spraying machine of the present invention has good medium applicability, and even the medium with poor fluidity can be sprayed at a relatively high pressure, and at the same time, the mechanical wear on the putty spraying machine is reduced.

Description

technical field [0001] The invention relates to the field of construction machinery and equipment, in particular to a two-way hydraulic putty spraying machine. Background technique [0002] At present, in the construction of building exterior walls and home decoration, it is necessary to apply putty, latex paint, paint, etc. to the wall, and some of them stay in manual operation with simple trowels, scrapers, and rollers. The work efficiency is low, and it is difficult to meet the construction progress requirements. [0003] Later, a plunger spraying machine was developed to spray putty. Its principle is to directly drive the plunger to move back and forth at high speed through the motor to generate pressure and spray the medium. However, for the medium with poor fluidity, the suction volume of the plunger cannot meet the requirements of normal work each time, and the high-speed movement of the plunger will only accelerate the mechanical wear. However, the existing hydraul...

AI Technical Summary

Problems solved by technology

However, for the medium with poor fluidity, the suction volume of the plunger cannot meet the requirements of normal work each time, and the high-speed movement of the plunger will only accelerate the mechanical wear

However, the existing hydraulic spraying machines on the market can only work through a single plunger. When the plunger cylinder sucks in the medium, the plunger cylinder will lose pressure, so the pressure working frequency is low.
