Plunger pump patching machine

The utility model relates to a plunger pump cement throwing jet, comprising an agitator, a pressure pump, an ejection gun and a power transmission device, characterized in that the agitator is composed of a sand pulp agitator and a deposit agitator, between which an oscillating screener cooperated with the two agitators is positioned. The out-feed channel of the sand pulp agitator is against the oscillation screener below which in turn is against an in-feed channel of the deposit agitator. The out-feed channel of the deposit agitator enters the plunger pump through a conduit and the outlet of the plunger pump is communicated with the ejection gun through a pulp transmission pipe. The high-pressure air pipe of an air pump is divided into two paths: a path is communicated with the pulp transmission pipe and the other path is communicated with the ejection gun. In the utility model, from mixing the sand pulp to ejecting the sand pulp on the wall except the manual striking off finally are mechanical works, which realizes mechanical plastering, greatly reduces the labor intensity of workers and improves working efficiency.
