[0001] The utility model relates to the technical field of concrete recycling, and more specifically, the utility model relates to a tunnel concrete spraying device with concrete recycling. Background Art

[0002] The primary support of a tunnel refers to the structural layer with relatively small stiffness constructed immediately after the tunnel excavation to control the appropriate release of surrounding rock stress and deformation, increase the structural safety factor and facilitate construction, and which is part of the permanent load-bearing structure. Shotcrete is sprayed on the structural layer. Shotcrete is to load the pre-prepared cement, sand, gravel, water and a certain amount of admixtures into a shotcreting machine, and use high-pressure air to send it to the nozzle where it is mixed with a quick-setting agent and then sprayed onto the surface of the rock or concrete at a very high speed. However, a large amount of concrete will fall off during the spraying process, resulting in waste. Therefore, in view of this problem, how to design a tunnel concrete spraying device with concrete recycling has become the problem that we need to solve currently. Summary of the Utility Model

The recovery paddle 5 is fixedly installed on the output end of the first motor 6. As Figure 3 shown, a conveying roller 7 is rotatably connected to the inside of the diversion hopper 3. A conveyor belt 8 is sleeved on the outside of the conveying roller 7. A second motor 9 is fixedly installed on one side of the diversion hopper 3. The conveying roller 7 is fixedly installed on the output end of the second motor 9. A feeding hopper 10 is fixedly installed on one side of the diversion hopper 3. A first conveying pipe 11 is communicated with the bottom of the feeding hopper 10. As Figure 1 shown, a first concrete pump 12 is fixedly installed on the top of the main body 1. The first conveying pipe 11 is communicated with the first concrete pump 12. A material box 13 is fixedly installed on the top of the main body 1.

[0021] It should be noted that when recycling the fallen concrete, the electric cylinder 2 is started to drive the diversion hopper 3 to descend, so that one side of the diversion hopper 3 can contact the ground. Then, when the main body 1 moves, the concrete can enter the inside of the diversion hopper 3. The first motor 6 is started to drive the recovery paddle 5 to rotate, and the concrete is pushed into the inside of the diversion hopper 3 by the recovery paddle 5. The concrete entering the diversion hopper 3 will fall on the top of the conveyor belt 8. At this time, the second motor 9 is started to drive the conveyor roller 7 to rotate, so that the conveyor belt 8 runs and drives the concrete into the feeding hopper 10. The first concrete pump 12 is started to send the concrete in the feeding hopper 10 into the material box 13, thus completing the recycling of the concrete. At this time, the third motor 15 can be started to drive the stirring shaft 14 to rotate, so as to stir the concrete in the material box 13, and then make the recycled concrete meet the use conditions, so as to realize the recycling of the concrete and avoid waste.

[0022] Furthermore, as Figure 1 shown, the first concrete pump 12 is communicatively connected to the material box 13. A stirring shaft 14 is rotatably connected inside the material box 13. A third motor 15 is fixedly installed on one side of the material box 13. The stirring shaft 14 is fixedly installed at the output end of the third motor 15. A second concrete pump 16 is communicatively provided on one side of the material box 13. A movable arm 17 is hinged to the top of the main body 1. A second delivery pipe 19 is communicatively connected to the top of the second concrete pump 16. A cylinder 18 is hinged to the bottom of the movable arm 17. The cylinder 18 is hinged to one side of the main body 1. A spray head 20 is fixedly installed at one end of the movable arm 17. The second delivery pipe 19 is communicatively connected to the spray head 20.

[0023] It should be noted that when spraying the concrete, the second concrete pump 16 is started to convey the concrete through the second delivery pipe 19 and spray it out through the spray head 20. Since the movable arm 17 is divided into multiple sections and each section can be controlled by the cylinder 18, the movable arm 17 can be in different states by controlling multiple cylinders 18, so as to meet the use requirements.
