Novel rotating extrusion assembly of extrusion pump

Abstract

A novel rotating extrusion assembly of an extrusion pump comprises a shell, a hose, a rotary plate and two clamping rollers. A first opening is formed in the upper end of the shell, and a second opening is formed in the lower end of the shell. A rotating shaft is arranged on the middle portion of the shell. A protruding part is arranged on the inner wall of the shell. The hose is arranged in the shell. One end of the hose penetrates the shell to the exterior of the shell from the first opening, and the other end of the hose penetrates the shell to the exterior of the shell from the second opening. The rotary plate is located in the shell and connected to the rotating shaft in a pivoted manner. Extrusion rollers are connected to the periphery of the rotary plate in a pivoted manner. The rotation axes of the extrusion rollers are parallel to the rotation axis of the rotary plate. The two clamping rollers are connected to the periphery of the rotary plate in a pivoted manner. The two clamping rollers are arrayed in the axial direction of the rotary plate and are oppositely arranged. The rotation axes of the clamping rollers are consistent with the radial direction of the rotary plate. A clamping part used for clamping the hose is formed by the opposite parts of the two clamping rollers. According to the novel rotating extrusion assembly, the clamping rollers are arranged on the rotary plate, the effect of preventing the hose from deviating and falling to the gap between the rotary plate and the shell is achieved, the effect of increasing lateral extrusion action points is also achieved, and the volume efficiency of the extrusion pump is improved.

Description

technical field [0001] The invention relates to a construction fluid machine, in particular to a novel extrusion pump rotating extrusion assembly. Background technique [0002] In the field of construction and decoration, it is often necessary to continuously transport a large amount of cement to the place where grouting is required. Therefore, engineers generally use pump equipment to power the cement, and then cooperate with pipelines to transport it to the target location. By extruding the flexible pipe, the cement is discharged section by section to the outlet of the pipe at the target position. At this time, if the flexible pipe is squeezed with extrusion pump equipment, the part of the flexible pipe inside the body will easily fall To the lateral gap between the rotating parts (such as the turntable) and the shell of the body, causing curling or locking. In addition, the extruding pump equipment in the prior art only relies on extruding rollers and some matching posit...

Problems solved by technology

By extruding the flexible pipe, the cement is discharged section by section to the outlet of the pipe at the target position. At this time, if the flexible pipe is squeezed with extrusion pump equipment, the part of the flexible pipe inside the body will easily fall To the lateral gap between the rotating parts (such as the turntable) and the body shell, causing curling or locking

In addition, the extruding pump equipment in the prior art only relies on extruding rollers and some matching positions in the equipment to extrude the hose together. It can be seen from experience that the volumetric efficiency of only the directional rotary extrusion of the hose is will be lower, in other words, this type of extrusion will be accompanied by a larger volume leak
