A concrete shotcrete machine used for building foundation reinforcement

Abstract

The invention belongs to the technical field of sandblasting machines, and discloses a concrete spraying machine used for building foundation reinforcement, which includes a device body, an upper rubber sealing ring and a lower rubber sealing ring. The device body includes a support frame, a motor, The pressing mechanism, the rotor body, the stirring box, the hopper and the nozzle cyclone, a lower snap ring is arranged between the rotor body and the support frame, and an upper snap ring is arranged between the rotor body and the stirring box. The present invention offsets the reaction force generated by the support spring after being compressed with the self-weight of the rotor body, reducing the additional self-weight pressure on the lower rubber sealing ring from the rotor body, so that the pressure on the upper rubber sealing ring and the lower rubber sealing ring is equal , thereby synchronizing the wear cycle of the upper rubber sealing ring and the lower rubber sealing ring, so that the upper rubber sealing ring and the lower rubber sealing ring can be replaced synchronously after the service life expires, thereby reducing the working pressure of maintenance personnel.

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
