Description

Technical Field

[0001] The utility model relates to the technical field of spraying machines, in particular to a concrete spraying machine which is easy to maintain. Background Art

[0002] A concrete spraying machine is a device used to spray concrete in underground projects such as tunnels and mines to achieve support purposes. A concrete spraying machine can spray concrete at high speed, greatly improving the construction speed, shortening the project cycle, achieving uniform spraying, providing good support effects, enhancing the stability and durability of the structure, reducing the labor intensity of operators, and improving the working environment.

[0003] In current concrete spraying machines, if the concrete storage cylinder is inactive for a long time and the concrete is not discharged in time, it is easy to solidify inside. Once this happens, since the storage cylinder is an integrated design, it becomes very difficult to remove and maintain the internal concrete, which increases the difficulty of maintenance work and may also affect the normal service life of the equipment.

[0004] Patent document CN218716831U discloses a concrete spraying machine, "including a base, a pushing assembly is fixedly provided on the top of the base, a support frame is fixedly provided on the top of the base, a support seat is fixedly provided on the outer side of the support frame, a first motor is fixedly provided on the support seat, a roller is fixedly provided on the output shaft of the first motor, a spray pipe is wound around the outer edge of the roller, and a nozzle is fixedly provided at one end of the spray pipe. Through the coordinated use of the support frame, the first motor, the roller, and the spray pipe, the spray pipe is wound around the outer edge of the roller, and the roller is driven to rotate on the support frame by the rotation of the first motor. The spray pipe can be wound and released by the forward and reverse rotation of the first motor. Winding up the spray pipe by the rotation of the first motor can be more convenient and labor-saving, and can effectively reduce the burden on the staff, reduce the work intensity, and make the work easier." However, the concrete spraying machine in the above-mentioned public document mainly considers the convenience of winding up the spray pipe, but does not consider the problem of quickly clearing and maintaining the solidified or accumulated concrete inside the storage cylinder. Therefore, it is necessary to develop a concrete spraying machine that is easy to maintain. Utility Model Content
