Concrete supporting machine

The utility model relates to a concrete supporting machine. The problems that in traditional shotcrete supporting, the concrete springback amount is large, the working environment is poor, operation is complex, and concrete raw materials are difficult to machine and screen are solved. Concrete is conveyed through the spiral conveying pipe and is flattened, vibrated and compacted. The difficulty that the spiral conveying pipe is not easy to bend is solved through the following main measures: two sections of spiral pipes are connected through a bent pipe; the spiral pipe is flexibly connected with the scraping plate; the receiving hopper is fixedly connected with the base plate and can rotate along with the base plate. And the method has the advantages of good working environment, no resilience, simplicity and convenience in operation and the like. 本实用新型为混凝土支护机。解决传统喷射混凝土支护中的混凝土回弹量大、作业环境差、操作复杂、混凝土原材料加工筛选难的问题。本实用新型采用螺旋输送管运送混凝土并抹平振捣密实。通过以下主要措施解决了螺旋输送管不易弯曲的困难：在两节螺旋管之间通过弯管连接；在螺旋管与刮板之间采用柔性连接；受料斗与底盘固接在一起，可以随着底盘一起旋转。具有
