Pedal type mortar pump

Abstract

The invention discloses a pedal type mortar pump. The pedal type mortar pump comprises a pump body, a diaphragm, a piston, a torsion spring, a connecting rod, a lever and taper plugs. An inlet of the pump body is positioned at the upper part; and an inlet and a large-hole end are coaxially arranged at the two sides. The piston pulled by the connecting rod is mounted in a cylinder; and the diaphragm is fixedly connected between the cylinder and the structural surface of the pump body. The taper plugs capable of axially reciprocating are respectively mounted in the inlet and an outlet of the pump body; and a vertical connecting pipe and a transverse connecting pipe externally connected respectively fit the taper plugs to form a one-way valve structure. The connecting rod consists of three parts respectively hinged to the middle part of the lever, the piston and the bottom of the cylinder to form a connecting rod mechanism for driving the piston to axially reciprocate. The piston in the cylinder moves to generate negative pressure or positive pressure to project the flexible diaphragm to the left or right side, so that the inner volume and pressure of the pump body are changed, and the one-way valve in the inlet or the outlet alternately acts to realize the absorption or the outputting of mortar. The pedal type mortar pump is simple in structure, is liable to operate, and reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to a construction machine, in particular, the invention relates to a pump for conveying concrete mortar, which is driven by a user's pedal. Background technique [0002] Wall-laying is a large-scale and wide-ranging work in building construction. Master bricklayers bond orderly arranged bricks by spreading paste-like mortar. During the project, the barrels containing the mortar are sent to the master bricklayer's operation station through mechanical transportation or auxiliary worker transportation, so that the master bricklayer can take it as needed. This kind of traditional technology is simple and reliable, and can satisfy the master bricklayer to take mortar materials nearby at the work station, which greatly facilitates construction. However, during the construction process, the master bricklayer has to bend down frequently to scoop the mortar, and then straighten up to send the taken mortar to the target position for paving...

AI Technical Summary

Problems solved by technology

However, during the construction process, the master bricklayer has to bend down frequently to scoop up the mortar, and then straighten up to send the taken mortar to the target position for paving. This operation not only consumes a lot of man-hours, but also increases the labor intensity of the master bricklayer.

In addition, the process of zero mortar extraction is prone to leakage, resulting in waste of raw materials and deterioration of the workplace environment
