During the rotation of the stirring rod 4, the auger rod 34 is driven to rotate by the transmission belt 6 and the two belt pulleys 5. After the slurry enters the pipe body 33, it is conveyed to the storage tank 8 through the action of the auger rod 34 to realize the storage of the slurry, and then the spraying operation can be carried out.

[0123] Since gas continuously enters the buffer air tank 14, when the air pressure in the buffer air tank 14 is higher than a certain level, the gas in the buffer air tank 14 enters the air delivery pipe 41 through the pressure relief valve 42, and then the high-pressure gas drives the mortar in the air delivery pipe 41 to the hose 13 through the connecting pipe 43, and finally sprays out through the spray head 12 to realize the shotcreting work.

[0124] Furthermore, the screeding assembly includes:

[0125] A collection box 31, both two side walls of the collection box 31 are rotatably connected with ear plates;

[0133] The electric winch 30 is fixed on the top of the trolley 1, and the winding shaft of the electric winch 30 is fixed to the connecting rope 29.

[0134] When spraying mortar, it is necessary to adjust the height of the collection box 31 through the cooperation of the electric winch 30 and the connecting rope 29, and adjust the position of the collection box 31 through the cooperation of the first motor 26 and the electric push rod 27, so that the collection box 31 can closely adhere to the wall. Then, the mortar flowing down along the wall during the spraying process can enter the collection box 31 and be collected by the collection box 31. Finally, by adjusting the height of the collection box 31, the output pipe 32 is moved above the mixing tank 2, and the end cover is opened to realize the recovery work of the mortar;

[0135] During the spraying process, the position of the spray head 12 is adjusted through the operation of the first electric slide table 9 and the second electric slide table 10, thereby realizing the spraying treatment of the entire wall;

[0136] After the spraying treatment, adjust the position of the collection box 31 so that the collection box 31 can be at a certain distance from the wall, and lift the collection box 31 at this distance to realize the mortar smoothing work on the side wall of the collection box 31.

[0137] The specific working method is as follows: When in use, put the raw materials into the mixing tank 2, turn on the switch of the second motor 38. When the second motor 38 works, it drives the stirring rod 4 to rotate to stir the mortar. During this process, turn on the switch of the air cylinder 36, and drive the sealing plate 37 to descend through the work of the air cylinder 36 to seal the pipe body 33, so that the mortar is always in the mixing tank 2 until the mortar in the mixing tank 2 is stirred to a certain degree;

[0138] Turn on the switch of the air cylinder 36, drive the sealing plate 37 to rise through the air cylinder 36, and the mortar in the mixing tank 2 enters the pipe body 33. During the rotation of the stirring rod 4, the auger rod 34 is driven to rotate through the transmission belt 6 and the two belt pulleys 5. After the mortar enters the pipe body 33, it is conveyed to the storage tank 8 through the action of the auger rod 34 to realize the storage of the mortar, and then the spraying operation can be carried out. During this process, the stirring rod 4 in the mixing tank 2 continues to rotate to realize the continuous production of the mortar;

[0139] Turn on the switch of the high-pressure air pump. When the high-pressure air pump works, it injects high-pressure gas into the buffer air tank 14 through the air supply pipe 15, so that the buffer air tank 14 is in a high-pressure environment;

[0140] Part of the gas in the buffer gas tank 14 enters the sleeve 20 through the three-way pipe 17 and the two first solenoid valves 18, pushing the piston 39 downward and stretching the spring 40. Subsequently, the first solenoid valve 18 is closed and the second solenoid valve 19 is turned on, so that the gas in the sleeve 20 is output through the second solenoid valve 19. Under the action of the spring 40, the piston 39 is driven to rise. By alternately controlling the states of the second solenoid valve 19 and the first solenoid valve 18, the reciprocating up and down movement of the piston 39 is achieved;

[0141] During the upward movement of the piston 39, the slurry in the storage tank 8 enters the sleeve 20 through the feed pipe 22 and the first one-way valve 21. During the downward movement of the piston 39, the slurry in the sleeve 20 enters the gas transmission pipe 41 through the second one-way valve 23 and the feed pipe 24;

[0142] Since gas continuously enters the buffer gas tank 14, when the air pressure in the buffer gas tank 14 is higher than a certain level, the gas in the buffer gas tank 14 enters the gas transmission pipe 41 through the pressure relief valve 42. Then, the high-pressure gas is used to drive the mortar in the gas transmission pipe 41 through the connecting pipe 43 to the hose 13 and finally sprayed out through the nozzle 12 to achieve the shotcreting work;

[0143] When carrying out the shotcreting work, it is necessary to adjust the height of the collection box 31 through the operation of the electric winch 30 in cooperation with the connecting rope 29, and adjust the position of the collection box 31 through the cooperation of the first motor 26 and the electric push rod 27, so that the collection box 31 can be closely attached to the wall. Then, the slurry left along the wall during the shotcreting process can enter the collection box 31 and be collected by the collection box 31. Finally, by adjusting the height of the collection box 31, the output pipe 32 is moved above the mixing tank 2, and the end cover is opened to achieve the recovery work of the mortar;

[0144] During the shotcreting process, the position of the nozzle 12 is adjusted through the operation of the first electric slide 9 and the second electric slide 10, and then the shotcreting treatment of the entire wall is achieved;

[0145] After the shotcreting treatment, adjust the position of the collection box 31 so that the collection box 31 can be at a certain distance from the wall, and lift the collection box 31 at this distance to achieve the mortar grinding work on the side wall of the collection box 31.
