Concrete spraying machine for building foundation reinforcement

Abstract

The invention belongs to the technical field of sand blasting machines, and discloses a concrete spraying machine for building foundation reinforcement. The concrete spraying machine comprises a device body, an upper rubber sealing ring and a lower rubber sealing ring, wherein the device body comprises a supporting frame, a motor, a pressing mechanism, a rotor body, a stirring box, a hopper and a connecting pipe cyclone; a lower clamping ring is arranged between the rotor body and the supporting frame; and an upper clamping ring is arranged between the rotor body and the stirring box. According to the concrete spraying machine, the counter-acting force generated after a supporting spring is compressed is counteracted with the self-weight of the rotor body, so that the extra self-weight pressure of the lower rubber sealing ring from the rotor body is reduced, the pressure borne by the upper rubber sealing ring and the lower rubber sealing ring is equal, the abrasion periods of the upper rubber sealing ring and the lower rubber sealing ring are synchronized, the upper rubber sealing ring and the lower rubber sealing ring can be synchronously replaced after the service life expires, and the working pressure of maintenance personnel is reduced.

Description

technical field [0001] The invention belongs to the technical field of sandblasting machines, in particular to a concrete spraying machine used for building foundation reinforcement. Background technique [0002] Concrete is the basic raw material for building construction. It is widely used in building foundation reinforcement and wall brick stabilization operations. In the process of building construction sites, concrete spraying machines are often required to be used with concrete delivery to complete the functions of filling the foundation and supporting the wall. , Concrete sandblasting machine is also widely used in the spraying of building exterior walls. [0003] At present, the working principle of the concrete shotcrete machine used for building foundation reinforcement is as follows: the concrete mortar after mixing is screened by the vibration of the hopper plate and enters the mixing box, and the material is moved by the feeder and injected into the through mate...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a concrete shotcrete machine used for building foundation reinforcement, to solve the above-mentioned problems in the background technology about the asynchronous wear of the upper and lower rubber rings, the inability to rotate synchronously, and the decrease in the discharge rate caused by the aggravation of wear, etc. question
