Abstract

A mining shotcreting machine includes elevating units. The elevating units include upper supports and lower supports. The lower ends of the upper supports are hinged to the upper ends of the lower supports through pins 1. A support plate is arranged on a bottom platform. Cylinder seats of a hydraulic cylinder A and a hydraulic cylinder B are respectively symmetrically fixed at the left and right sides of the support plate. Piston rod heads of the hydraulic cylinder A and the hydraulic cylinder B are respectively connected to the middle parts of the pins 1 in the elevating units at the left side and the right side. Two connection seats are arranged at the left end and the right end of the bottom platform. The lower ends of the lower supports in the two elevating units are hinged to the connection seats at the left end and the right end of the bottom platform through pins 2. A rotary seat is formed by a bottom plate and two side plates at the front end and the rear end of the bottom plate. A pin 3 is rotatably arranged at each of the left end and the right end of the two side plates. A gear is fixedly arranged at the middle part of each pin 3. Two gears are engaged with each other. The upper ends of the upper supports in the two elevating units are respectively fixedly connected to the front end and the rear end of the two pins 3. The mining shotcreting machine has simple stricture, small land occupation, and strong versatility.

Description

technical field [0001] The invention relates to the technical field of coal mine equipment, in particular to a mine shotcrete machine. Background technique [0002] The existing spraying machine is not suitable for mine spraying operation due to the long swing arm for installing the nozzle, large volume and inflexible operation, especially when the working space is small. Contents of the invention [0003] Aiming at the problems existing in the above-mentioned prior art, the present invention provides a mine shotcrete machine, which has a simple structure, a small footprint and strong versatility. [0004] In order to achieve the above purpose, the present invention provides a mine shotcrete machine, which includes a bottom platform, two lifting units symmetrically arranged on the left and right sides of the bottom platform, hydraulic cylinders A and B arranged horizontally, fixedly arranged on the bottom The swivel seat at the center of the upper part of the platform, th...
