When in use, concrete enters from the wet spraying machine hopper, is evenly sent to the air-material mixing bin through the feeding system, and is mixed with high-pressure air in a thin flow state through the spray pipe to the nozzle. The liquid accelerator addition system adjusts the flow rate of the metering pump according to the liquid accelerator dosage. The liquid accelerator pumped out is mixed with high-pressure air through the atomizer, and after atomization, it is mixed with the concrete in a thin flow state in the nozzle mixing ring and sprayed from the nozzle to the sprayed surface.

At this time, the third hydraulic rod 71 is controlled to work to move the rotor body 3. Thereby, the rotor body 3 can be disassembled and assembled by hydraulic means, and the speed and efficiency of disassembly and assembly are improved.

[0041] In order to achieve the spraying of concrete. Figure 1-Figure 4A mixing chamber 8 is fixedly provided at the bottom end of the base 2, a spray head 9 is provided at the front end of the mixing chamber 8, and an air source distribution mechanism 10 connected to the mixing chamber 8 is fixedly provided on the base 2.

The output end of the air source distribution mechanism 10 is connected to the batching disk 5 and the spray head 9 through pipelines. High-pressure air is blown into the batching disk 5 and the spray head 9 respectively through the air source distribution mechanism 10, so as to move the concrete in the rotor body 3 to the mixing chamber 8 for mixing more quickly, and at the same time provide power for the concrete sprayed at the spray head 9.

[0042] In order to achieve the control of each mechanism of the equipment. Figure 1-Figure 4 A control module 11 for driving the rotor body 3, the limiting unit 6 and the lifting unit 7 is fixedly arranged on the supporting base 1 at the side of the rotor body 3. The control module 11 includes a hydraulic oil tank 111, a hydraulic motor 112, a control unit 113, a flow divider 114 and a driving motor 115.

[0043] The hydraulic oil tank 111 is fixedly arranged on the support base 1, and the hydraulic motor 112 is arranged on the hydraulic oil tank 111 to provide power for the flow of oil. The diverter 114 is respectively fixedly arranged on the support base 1 and the end of the control unit 113 and is connected to each other through an oil pipe, and the hydraulic oil tank 111 is connected to the corresponding diverter 114 through an oil pipe. A pressure controller 116 fixed on the corresponding diverter 114 is also arranged above the support base 1. The drive motor 115 is fixedly arranged on the base 2 to drive the rotor body 3 to rotate. The diverter 114 is connected to the corresponding first hydraulic rod 19, the second hydraulic rod 61 and the third hydraulic rod 71 through an oil pipe. The control of each component is realized through the control module 11, which is convenient for the use of the staff and the spraying operation.

[0044] In order to achieve the control of the feeding amount. Figure 4 and Figure 5, a material discharge module 12 for controlling the amount of concrete discharge is arranged inside the rotor body 3. The material discharge module 12 includes a fixed block 121 fixedly arranged at the lower part of the batching chamber 16, and a screw 122 is rotatably arranged at the top of the fixed block 121. A limit ring 123 is coaxially arranged inside the batching chamber 16, and the limit ring 123 is threadedly connected with the screw 122. A guide column 124 penetrating the limit ring 123 is vertically fixedly arranged at the top of the fixed block 121 on the side of the screw 122, and a turning rod 125 is sleeved on the guide column 124. A blocking block 126 that can block the middle space of the limiting ring 123 is fixedly arranged at the end of the turning rod 125, and a blocking block 127 that blocks the limit position of the blocking block 126 is fixedly arranged on the inner ring of the limiting ring. A second spring 128 is arranged between the turning rod 125 and the fixed block 121, and an elastic sleeve 129 is sleeved between the turning rod 125 and the fixed block 121 outside the second spring 128. The second spring 128 is shielded by the elastic sleeve 129 to prevent the concrete from blocking the operation of the second spring 128. The top of the shielding block 126 is threadedly connected to a vertical rod 130, and the top of the vertical rod 130 is hinged with a ball 131, and the upper half of the ball 131 extends out of the top of the batching chamber 16. The ball 131 hinged at the top of the vertical rod 130 reduces resistance.

[0045] Before the equipment is working, the position of the limit ring 123 is adjusted by rotating the screw 122. At this time, the upper and lower positions of the blocking block 126 are changed with the position of the limit ring 123 through the second spring 128 and the blocking block 127, thereby changing the amount of concrete entering the batching chamber 16. When the rotor body 3 rotates, the concrete enters the batching chamber 16 through the material distribution port 22. At this time, the concrete is above the limit ring 123 and the blocking block 126. The rotor body 3 continues to rotate. At this time, the edge of the material distribution port 22 will squeeze the ball 131, so that the blocking block 126 overcomes the resistance of the second spring 128 and moves downward along the guide column 124, contacting the blocking block 126 to block the limit ring 123. At this time, the concrete enters the bottom of the limit ring 123 with the high-pressure gas, and enters the mixing chamber 8 from the discharge port. Thereby, the concrete discharge amount is controlled.

[0046] The method of using the rotor type concrete spraying machine of the utility model is as follows: first, when assembling the rotor body 3, the bolts on the connecting rod 17 are unscrewed, and then the through hole 76 is set on the connecting rod 17, and the bolts are re-screwed. At this time, the third hydraulic rod 71 is controlled by the control unit 113 to work and move the rotor body 3 to the base 2. Then the first hydraulic rod 19 is controlled by the control unit 113 to work, and the batching plate 5 is turned around the hinge point between it and the fixed frame 18 to the rotor body 3 and fit the top of the rotor body 3. The limiting column 62 is located above the limiting plate and the second hydraulic rod 61 is controlled by the control unit 113 to work, so as to limit the height direction of the rotor body 3 to avoid swinging during its rotation, resulting in concrete entering the gap and affecting the service life. In this process, the hydraulic motor 112 is controlled by the control unit 113 to drive the oil in the hydraulic oil tank 111 to each mechanism. At this time, the rotor body 3 is protected by the upper support plate 15 and the lower support plate 14 to extend the service life of the rotor body 3. Then the sieve bucket 42 and the lower material bin 41 are installed above the batching plate 5. The device is convenient to move in the mine hole by the moving wheel 13.

[0047] Then, the position of the limit ring 123 is adjusted by rotating the screw rod 122 . At this time, the upper and lower positions of the blocking block 126 are changed along with the position of the limit ring 123 by the second spring 128 and the blocking block 127 , thereby changing the amount of concrete entering the batching chamber 16 .

[0048] When the spraying operation starts, the control unit 113 controls the driving motor 115 to work, thereby driving the rotor body 3 to rotate and pouring the mixed concrete from the screen bucket 42 into the lower material bin 41. At this time, the concrete entering the lower material bin 41 is divided into the concrete above the batching disk 5 through the distribution port 22, so that the concrete enters the batching chamber 16. At this time, the concrete is above the limit ring 123 and the shielding block 126. The rotor body 3 continues to rotate, and the edge of the distribution port 22 squeezes the ball 131, so that the shielding block 126 overcomes the resistance of the second spring 128 and moves downward along the guide column 124, contacting the shielding block 126 to the limit ring 123. The control unit 113 controls the air source distribution mechanism 10 to work, and blows high-pressure air into the batching disk 5. At this time, the concrete enters the lower part of the limit ring 123 with the high-pressure gas, and enters the mixing chamber 8 from the discharge port to mix with the high-pressure air. Thereby, the control of the concrete discharge amount is realized. At the same time, the high-pressure air provides power for the concrete sprayed at the spray head 9. The concrete is sprayed out from the spraying head 9 .
