Horizontal type spraying machine

Abstract

The invention discloses a horizontal sprayer which comprises a feeding host and a hopper arranged at the upper part of the feeding host, wherein the feeding host is composed of a framework and a rotor; a rotor shaft is connected with a power outputting device in a driving manner; the feeding host comprises a stator and the rotor which are horizontally arranged on the framework; material grooves are arranged on the circumference of the cylindrical surface of the rotor at intervals; a hopper is arranged above the stator; a lower opening of the hopper is communicated with a stator cavity and located corresponding to the position of the material grooves on the rotor; an air inlet and an air outlet which are communicated with the cavity are arranged below the stator, and the opening position is corresponding to the position of a single material groove on the rotor; the air inlet is communicated with an air outputting port of a high pressure gas generating device. The horizontal sprayer can carry out an impulse-type continuous spraying operation, shorten the feeding time; the time interval for each spraying is short; and the maintenance is reduced and the work efficiency is improved.

Description

Technical field [0001] The invention relates to a wet concrete shotcrete machine, in particular to a horizontal shotcrete machine. Background technique [0002] The feeding mechanism of the existing concrete rotor wet shotcrete machine adopts a vertical structure. The two ends of the rotor are provided with vertical through holes along the axial direction as the material cavity. The upper and lower openings of the rotor material cavity are sealed by upper and lower sealing plates. The upper sealing plate is provided with a feed port corresponding to the position of the upper mouth of the rotor material cavity, the upper part of the feed port corresponds to the hopper discharge port, the lower sealing plate is opened with a discharge port corresponding to the diameter of the round pipe, and the discharge port is connected to the outlet The material pipe is also provided with an air inlet pipe on the upper sealing plate directly above the discharge port. When the shotcrete machine ...

AI Technical Summary

Problems solved by technology

The material cavity of this rotor type shotcrete machine is a circular tube material cavity. In order to prevent air leakage, the caliber of the existing circular tube material cavity is smaller than its height, which leads to a slow speed of feeding and discharging materials at the upper and lower openings of the circular tube. In order to ensure the concrete The slurry can fill the material cavity of the round tube in time, either reduce the volume of the material cavity to increase the feeding speed, or increase the feeding time to reduce the work efficiency; in addition, considering the volume of the whole machine, the diameter of the rotor cannot be made too large, Therefore, the diameter of the round tube material cavity is also restricted. The feed port of the circular tube material cavity is not very easy to be closed by the viscous concrete at the outlet of the hopper, resulting in the air in the circular tube material cavity cannot be discharged, making the concrete more difficult. Into the material cavity, the structural defect of the rotor material cavity causes the existing rotor type wet shotcrete machine to have low working efficiency and easy to block

In addition, the inlet and outlet ports are set on the sealing plate, and the leaked concrete slurry will easily enter between the sealing plate and the end face of the rotor material cavity during material feeding and discharging, which will aggravate the wear of the sealing plate. The existing shotcrete machine needs to frequently replace the sealing plate , and needs to be shut down for replacement, which is not conducive to construction and increases the cost of use
