[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figure 1-6 The present invention discloses a flow rate adaptive highway engineering shotcrete trolley equipment, including a base plate 1, a driver's cab 34 is provided at one end of the top of the base plate 1, a moving part is fixedly connected to the other end of the top of the base plate 1, and an adjusting spraying mechanism is provided between the driver's cab 34 and the moving part.

[0027] The spraying mechanism includes a raw material storage section, which is located between the cab 34 and the moving part and is fixedly connected to the top of the base plate 1. The bottom of the raw material storage section is connected to one end of the conveying section, and the other end of the conveying section passes through the moving part and is connected to the nozzle 14. The nozzle 14 is provided with an auxiliary material addition section, a water outlet section, and a flow rate adjustment section from top to bottom.

[0028] By setting a flow adjustment section at the bottom of nozzle 14, the flow rate of concrete during concrete spraying can be adjusted, improving work efficiency. The water outlet section can form water mist during dry spraying, reducing the dust content in the air. After spraying, water can be injected into nozzle 1, material conveying section and raw material storage section through the water outlet section to clean their interiors. The auxiliary material addition section can add auxiliary materials such as accelerators into nozzle 14 to improve the performance of concrete. The moving part can move nozzle 14 to change its position within a certain range, increasing the spraying coverage and improving work efficiency.

[0029] The flow regulation unit further optimizes the design by including an regulating ring 15, which is fixedly mounted at the bottom of nozzle 14. Inside the regulating ring 15, there are corresponding rotating rings 31 and several moving blocks 28. The rotating rings 31 are rotatably mounted inside the regulating ring 15. Handles 16 are fixedly connected to the two opposite ends of the outer ring of the rotating ring 31. The regulating ring 15 has a sliding hole 32, and the handles 16 are slidably mounted inside the sliding hole 32. Several elongated holes 33 are opened on the rotating ring 31, and several moving blocks 28 are slidably mounted inside the regulating ring 15. A vertically mounted connecting rod 29 is fixedly connected to one end of the top of the moving block 28 near the outer ring of the regulating ring 15. The other end of the connecting rod 29 passes through the strip hole 30 opened in the regulating ring 15 and is slidably mounted inside the elongated hole 33.

[0030] In the initial state, the connecting rod 29 is located at the end of the elongated hole 33 near the outer ring of the adjusting ring 15, and the moving block 28 is located inside the adjusting ring 15. When it is necessary to adjust the concrete spray volume of the nozzle 14, the rotating ring 31 is rotated clockwise by the handle 16. During the rotation of the rotating ring 31, the connecting rod 29 slides towards the end near the inner ring of the adjusting ring 15 inside the elongated hole 33. During the sliding process of the connecting rod 29, due to the restriction effect of the strip hole 30, it will drive the moving block 28 to slide straight out of the adjusting ring 15. As the moving block 28 slides out, the area of ​​the circular hole in the inner ring of the adjusting ring 15 will gradually decrease, thereby reducing the concrete flow rate. To increase the concrete flow rate, the adjusting ring 15 is rotated counterclockwise.

[0031] The design is further optimized so that the water outlet section includes a lower fixing plate 18, which is fixedly installed in the middle of the nozzle 14. The lower fixing plate 18 has a lower annular cavity 20 inside, which is connected to the material conveying section. The bottom of the lower annular cavity 20 has several vertical water channels 21, which are equally spaced around the nozzle 14. A first electrically controlled valve 23 is installed in the vertical water channel 21. The bottom of the vertical water channel 21 is connected to the nozzle 29. The side of the lower annular cavity 20 near the nozzle 14 has several horizontal water channels 22, which are equally spaced around the nozzle 14. A second electrically controlled valve 24 is installed in the horizontal water channel 22.

[0032] When using the dry spraying method to spray concrete, the second solenoid valve 24 is closed and the first solenoid valve 23 is opened. The high-pressure water in the water pipe 6 enters the lower ring cavity 20 and is sprayed out from the nozzle 19 through the vertical water channel 21, forming a water mist to neutralize the concrete dust in the air and reduce the dust content. When using the wet spraying method to spray concrete, water mist is not required. In this case, the first solenoid valve 23 and the second solenoid valve 24 are closed simultaneously. After the concrete spraying work is completed, when it is necessary to clean the inside of the equipment, the first solenoid valve 23 is closed and the second solenoid valve 24 is opened. The high-pressure water in the water pipe 6 is backflowed into the nozzle 14 through the lower ring cavity 20 and the vertical water channel 21 to begin cleaning the inside of the equipment.

[0033] Further optimization of the scheme: the auxiliary material addition section includes an upper fixing plate 17, which is fixedly installed on the top of the nozzle 14. An upper annular cavity 25 is opened inside the upper fixing plate 17, which is connected to the material conveying section. Several horizontal auxiliary material channels 26 are opened on the side of the upper annular cavity 25 near the nozzle 14. Several horizontal auxiliary material channels 26 are equally spaced around the nozzle 14. A third electric control valve 27 is installed in the horizontal auxiliary material channel 26.

[0034] During the shotcrete process, the third electric control valve 27 is opened, and auxiliary materials such as quick-setting agent enter the upper ring cavity 25 through the auxiliary material pipe 8, and then enter the nozzle 14 through the horizontal auxiliary material channel 26 to mix with the concrete and improve the performance of the concrete.

[0035] The scheme is further optimized. The material conveying section includes a water pump 5, an auxiliary material pump 7, and a discharge hose 11. The water inlet of the water pump 5 is connected to the raw material storage section. The water outlet of the water pump 5 is connected to one end of a water pipe 6. The other end of the water pipe 6 passes through the moving part, the upper fixed plate 17, and the lower annular cavity 20 opened in the lower fixed plate 18. The feed inlet of the auxiliary material pump 7 is connected to the raw material storage section. The discharge outlet of the auxiliary material pump 7 is connected to one end of an auxiliary material pipe 8. The other end of the auxiliary material pipe 8 passes through the moving part and is connected to the upper annular cavity 25 opened in the upper fixed plate 17. One end of the discharge hose 11 is connected to the raw material storage section. The other end of the discharge hose 11 is connected to one end of a material conveying pipe 12. The other end of the material conveying pipe 12 passes through the moving part and is connected to one end of a connecting elbow 13. The other end of the connecting elbow 13 is connected to the top of the nozzle 14.

[0036] The scheme is further optimized. The raw material storage section includes a raw material box 2, a water tank 3, and an auxiliary material box 4. The raw material box 2, water tank 3, and auxiliary material box 4 are fixedly installed on the top of the base plate 1. The water tank 3 and the auxiliary material box 4 are arranged side by side at one end near the cab 34. The raw material box 2 is located at one end near the moving part. The bottom of the raw material box 2 is connected to the discharge hose 11. The bottom of the water tank 3 is connected to the water inlet of the water pump 5. The bottom of the auxiliary material box 4 is connected to the feed inlet of the auxiliary material pump 7.

[0037] Water pump 5 pumps water out of water tank 3 and into lower annular cavity 20 through water pipe 6. During dry concrete spraying, the water in lower annular cavity 20 is sprayed out through nozzle 2 19 to form water mist, reducing the dust content in the air. During internal cleaning of the equipment, the water in lower annular cavity 20 enters nozzle 1 14 and the equipment through horizontal water channel 22 to achieve the cleaning process. Auxiliary material pump 7 pumps accelerator and other auxiliary materials in auxiliary material box 4 into auxiliary material pipe 8, and then into nozzle 1 14 through upper annular cavity 25 and horizontal auxiliary material channel 26 to mix with concrete and improve concrete performance. Concrete in raw material box 2 enters nozzle 1 14 through discharge hose 11, conveying pipe 12, and connecting elbow 13 and is sprayed out.

[0038] The design is further optimized. The moving part includes two parallel and vertically arranged uprights 35. The bottom end of the uprights 35 is fixedly connected to the top end of the base plate 1. A horizontal beam 36 is fixedly connected between the top ends of the two uprights 35. A groove 41 is opened at the bottom end of the horizontal beam 36. A connecting part is slidably arranged in the groove 41. A vertical plate 37 is rotatably connected to the bottom end of the connecting part. A water pipe 6, an auxiliary material pipe 8, and a material conveying pipe 12 are inserted into the vertical plate 37.

[0039] The scheme is further optimized. The connecting part includes a slider 38, which is slidably disposed in the slide groove 41. A connecting shaft 39 is fixedly connected to the bottom end of the slider 38. A circular plate 40 is fixedly connected to the bottom end of the connecting shaft 39. The connecting shaft 39 is rotatably connected to the vertical plate 37. The circular plate 40 is rotatably disposed in the vertical plate 37.

[0040] During the shotcrete process, the left and right position of the nozzle 14 can be adjusted by sliding the slider 38 left and right in the chute 41. At the same time, rotating the vertical plate 37 can adjust the angle of the nozzle 14, thereby increasing the shotcrete spraying range and improving work efficiency.

[0041] Further optimization of the scheme: the top of the raw material box 2 is connected to the pressurization unit, which includes an air compressor 9. The air compressor 9 is fixedly installed on the top of the base plate 1. The outlet of the air compressor 9 is connected to one end of an air pipe 10, and the other end of the air pipe 10 is connected to the top of the raw material box 2.

[0042] Pressure is applied to the material box 2 by the air compressor 9 to facilitate the spraying of concrete. A pressure regulating valve and a pressure gauge can be installed on the air pipe 10 to adjust the pressure inside the material box 2 and monitor the pressure value.

[0043] Furthermore, wheels 42 are provided at the four corners of the bottom of the base plate 1 to facilitate the transfer and movement of the device.

[0044] The working process of this embodiment is as follows:

[0045] When spraying concrete, the device filled with raw materials is first moved to the corresponding road section, and then the concrete spraying begins. When it is necessary to adjust the concrete flow rate during the spraying process, the handle 16 drives the rotating ring 31 to rotate. During the rotation of the rotating ring 31, the moving block 28 extends or retracts the adjusting ring 15, changing the area of ​​the inner circle of the adjusting ring 15, thereby achieving the purpose of adjusting the concrete flow rate. During the spraying process, the auxiliary materials in the auxiliary material box 4 enter the upper ring cavity 25 through the auxiliary material pipe 8, and enter the nozzle 14 through the horizontal auxiliary material channel 26 to mix with the concrete and improve the performance of the concrete. If dry concrete spraying is performed, during the spraying process, the first electric control valve 23 is opened and the second electric control valve 24 is closed, so that the water in the lower ring cavity 20 is sprayed out through the nozzle 2 19 to form a water mist, reducing the dust content in the air. After the spraying is completed, the first electric control valve 23 and the third electric control valve 27 are closed, the second electric control valve 24 is opened, and the outlet of the nozzle 14 is closed at the same time, so that the water in the lower ring cavity 20 flows back into the equipment to clean the inside of the equipment.
