Horizontal type concrete spraying machine

Abstract

The invention discloses a horizontal concrete sprayer, wherein, a feeding mechanism comprises a framework and a rotor material cavity which is rotationally arranged on the framework and connected with a driving mechanism in a driving mode; the rotor material cavity and a central revolving shaft thereof are arranged horizontally; a material cavity body enclosed on the outer circumference of the central revolving shaft is a groove-typed material cavity body in which a plurality of groove openings are cut on the circumferential surface and the length direction of the groove openings extends in an axial direction; the feeding mechanism also comprises cylinder shell-shaped stators which are sleeved on the outer circumferences of all the groove-typed material cavity bodies of the rotor materialcavity and fixed on the framework; a sealing device is arranged at the joint where the circumferential surface and the end surface of the rotor material cavity are jointed with the stator; a feeding port matching with a hopper is cut at the upper part of the circumference of the stator; and an air inlet pipe and a discharging pipe are inserted into the stator so as to match and communicate with the same groove-typed material cavity body of the rotor material cavity. The groove-typed material cavity has larger groove opening area, shorter concrete running time in the material cavity and smoothdischarging without blocking the discharging port of the hopper. The discharging and charging speeds are fast owing to the larger groove opening area.

Description

technical field [0001] The invention relates to a wet-process concrete spraying machine, in particular to a horizontal concrete spraying machine. Background technique [0002] The core component of the feeding mechanism of the existing concrete rotor wet spraying machine is the rotor material cavity, and the circumference of the rotor material cavity has a vertical circular tube with upper and lower openings as the material cavity, and the top and bottom surfaces of the rotor material cavity pass through the upper and lower , the lower sealing plate for sealing, the upper sealing plate has a feed port corresponding to the caliber of the round pipe, the upper part of the feeding port corresponds to the lower material opening of the hopper, and the lower sealing plate has a discharge port corresponding to the caliber of the round pipe. The discharge pipe is connected to the discharge port, and there is an air inlet pipeline on the upper sealing plate directly above the dischar...

AI Technical Summary

Problems solved by technology

The concrete bearing chamber of the rotor material chamber of this shotcrete machine is a round pipe. In order to prevent air leakage, the caliber of the existing round pipe chamber is smaller than its height, which leads to a slow speed of feeding and discharging the upper and lower openings of the round pipe. To ensure that the concrete can fill the material cavity of the circular tube and be discharged from it in time, the speed of feeding and discharging can only be increased at the cost of reducing the volume of the material cavity. The concrete is closed, so that the air in the circular tube material cavity cannot be discharged, making it more difficult for concrete to enter the material cavity, and the structural defects of the rotor material cavity lead to the low working efficiency and easy blockage of the existing rotor type wet shotcrete machine

In addition, the inlet and outlet ports are set on the sealing plate, and the leaked concrete 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 replace the sealing plate frequently. And it needs to be shut down for replacement, which is not conducive to construction and increases the cost of use
