Method for preventing mortar spraying machine from being blocked and sieving dust hopper device

Abstract

The invention discloses a method for preventing a mortar spraying machine from being blocked. The method comprises the following steps of: preparing a sieving dust hopper device, wherein the sieving dust hopper device comprises a dust hopper; arranging a grid layer on a material discharge hole at the bottom of the dust hopper, and a movable grid layer which is movably arranged and can be taken out in the dust hopper; fixing an electrodynamic vibrator on the dust hopper, wherein the sizes of the holes in movable grid layer are smaller than those of the holes in the grid layer; arranging the sieving dust hopper device above a dust groove of the mortar spraying machine by using an elastic component; and staring the electrodynamic vibrator on the sieving dust hopper device when the mortar spraying machine works to block coarse aggregate and foreign matter mixed in the mortar material by using the movable grid layer and the grid layer in the sieving dust hopper device, and taking the movable grid layer out from the dust hoper and removing the coarse aggregate and foreign matter. Therefore, the coarse aggregate and foreign matter are prevented from entering a spray gun nozzle, a pipe, or a pump of the mortar spraying machine to effectively avoid the blocking phenomenon.

Description

technical field [0001] The invention relates to the field of mechanical engineering and building construction, in particular to a method capable of effectively preventing blockage of a pipeline or a pump of a mortar spraying machine and a sieving ash hopper device implementing the method. Background technique [0002] In the prior art, once coarse aggregate or foreign matter exists in the mortar material sprayed by the mortar spraying machine, it is very easy to block the pipeline and the pump. This not only greatly reduces the work efficiency of the equipment, but also increases the wear and tear of the equipment, and even directly damages the equipment. Although, the prior art can solve the above-mentioned problems to a certain extent on the supporting vibrating screen in the mortar spraying machine ash tank. However, to remove the coarse aggregate and foreign matter filtered out by the vibrating screen, the whole set of movable sieve needs to be lifted out, which makes t...

AI Technical Summary

Problems solved by technology

However, to remove the coarse aggregate and foreign matter filtered out by the vibrating screen, the whole set of movable sieve needs to be lifted out, which makes the work of removing coarse aggregate and foreign matter more cumbersome, which will affect the production and construction, and limit the scope of application of the mortar spraying machine.
