the combined reversing valve body 602 comprises a first elbow 603 and a first ball valve 604, wherein two ends of the first elbow 603 are respectively connected with the air compressor 601 and the first ball valve 604; the combined reversing valve body 602 further comprises a four-way joint 605, a second elbow 606 and a second ball valve 609, a pair of ports of the four-way joint 605 are respectively connected with the first ball valve 604 and the second elbow 606, the other end of the second elbow 606 is connected with the gas conveying pipeline 607, the other pair of ports of the four-way joint 605 is respectively connected with a pressure measuring meter 608 and a third ball valve 610, and the other end of the pressure measuring meter 608 is connected with the second ball valve 609; one end of the third ball valve 610 is provided with a pagoda joint 611 for externally connecting a hose, and the switch of the first ball valve 604, the second ball valve 609 and the third ball valve 610 is reversed to realize the delivery of the compressed gas.

Further, the gas delivery pipe 607 is further connected to the rapid hardening medium delivery device 5 to provide a delivery pressure for the rapid hardening medium delivery device 5.

This embodiment sets up gas compression device 6 in the front frame, and gas compression device 6 is closer with the distance of arm body telescoping device 4, only needs to set up a combination switching-over valve body 602 and can realize gaseous switching-over and output, has not only reduced laying of pipeline, also makes the loss of pressure among the compressed gas transportation process reduce, has guaranteed the pressure and the flow of compressed gas output, improves device concrete spray-seeding efficiency and quality.

The concrete wet spraying machine also comprises a waterway device 7, a hydraulic control device 9, a cable drum 14, an electric control device 10 and an illuminating lamp 12; the hydraulic control device 9 is respectively connected with the power device 2, the arm body expansion device 4, the cable drum 14, the pumping device 3 and the lubricating supply device 8; the electric control device 10 is respectively connected with the hydraulic control device 9, the compressed gas device and the illuminating lamp 12; the quick setting medium conveying device 5 is controlled by a hydraulic control device 9 or an electric control device 10.

Further, the present disclosure may also provide another embodiment based on the foregoing embodiment, which is as follows:

wherein, concrete wet blasting machine still includes the feeder hopper that is used for placing the concrete, and the feeder hopper is installed on truck frame body 1, and connects concrete pumping system.

In the embodiment, the stirred concrete is loaded into the feed hopper through the forklift, so that the concrete wet spraying machine can continuously work, and the working efficiency of the wet spraying machine is greatly improved.

The present disclosure has been described in detail above, and the principles and embodiments of the present disclosure have been explained herein using specific examples, which are provided only to assist understanding of the present disclosure and the core concepts. It should be noted that, for those skilled in the art, it is possible to make several improvements and modifications to the present disclosure without departing from the principle of the present disclosure, and such improvements and modifications also fall within the scope of the claims of the present disclosure.
