Gradual-changing mortar spraying device for spray coating

Abstract

The invention discloses a gradual-changing mortar spraying device for spray coating. The gradual-changing mortar spraying device for spray coating comprises a spraying machine frame, a screw pump, a motor and a feeding bin. A square sleeve is connected to one end of a conveying pipe, a spraying mechanism is installed on one side of the square sleeve, a positioning installation plate is welded to the top end of an electric push rod, a spraying strip is rotatably connected to the top end of the positioning installation plate through a hinge base, a plurality of spraying chambers are formed in the spraying strip, and a triangular baffle is welded to one end of the spraying strip. The gradual-changing mortar spraying device for spray coating is scientific, reasonable, and safe and convenient to use; by arranging the spraying mechanism, multi-angle adjustment of the spraying direction is facilitated, including up-down dip angle adjustment, height adjustment and lateral adjustment, and thusthe purpose of changing the direction during spraying is achieved; and by arranging the spraying strip and the spraying chambers, strip-shaped mortar is sprayed out, the situation that a spraying guncannot spray mortar uniformly is reduced, the uniformity of wall mortar after spraying is improved, and the spraying effect is better.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a gradient mortar spraying device for spraying. Background technique [0002] During building construction, it is necessary to spray mortar onto the building wall for plastering, which is called "machine spraying" plastering in the industry. When the existing mortar spraying machine drives the pump shaft to rotate through the motor, the screw in the screw pump rotates. , A sealed cavity is formed between the screw blade and the pump body. The mortar in the sealed cavity is pushed forward by one pitch every time the screw rotates. With the continuous rotation of the screw, the mortar is pressed from one sealed cavity to the other in a spiral manner. , after extruding the pump body, a Chinese open patent for spraying with a gradient mortar spraying device (authorized notification number CN 107035117 B), the patent technology center, by adding rocker arms and push rods...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a gradual change mortar spraying device for spraying, which can effectively solve the above-mentioned background technology. During actual use, due to the swing of the rocker arm and the push rod, the mortar coating in the middle of the front is thicker, upward and downward. Gradually thinning, resulting in uneven overall spraying and poor spraying effect
