The support plate is arranged at the output end of the driving motor 5. A fixed adjusting member 6 is provided on the support plate 3. The output pipe 4 is arranged on the fixed adjusting member 6. A concrete conveying member 7 is provided on the mobile vehicle 1. The height of the output pipe 4 can be adjusted by the hydraulic cylinder 2, and the driving motor 5 rotates forward and backward to adjust the orientation of the output pipe 4.

[0020] The fixed adjusting member 6 includes a connecting seat 8, a support plate 9, and a clamping ring 10. A groove 11 is provided at the end of the support plate 3. A rotating shaft penetrates through the groove 11. A driving member 12 is provided between the rotating shaft and the support plate 3. The connecting seat 8 is fixedly sleeved on the rotating shaft. The end of the support plate 9 is arranged on the connecting seat 8. A through groove 13 is provided on the bottom wall of the support plate 9. One end of the clamping ring 10 is rotatably hinged to one end of the top of the support plate 9. A connecting member 14 is provided between the other end of the clamping ring 10 and the other end of the top of the support plate 9. A fastening bolt is threadedly connected to the clamping ring 10. The output pipe 4 is placed between the support plate 9 and the clamping ring 10. The output pipe 4 can be fixed on the support plate 9 by the cooperation of the clamping ring 10 and the fastening bolt.

[0021] The concrete conveying member 7 includes a concrete pump 15 and a conveying pipe 16. The concrete pump 15 is arranged on the mobile vehicle 1. One end of the conveying pipe 16 is connected to the output end of the concrete pump 15. The other end of the conveying pipe 16 passes through the through groove 13 and is connected to the output pipe 4. The concrete is pumped into the conveying pipe 16 by the concrete pump 15, and the conveying pipe 16 sends it into the output pipe 4 for distribution.

[0022] The driving member 12 includes an electric telescopic rod 17 and a connecting plate 18. The end of the connecting plate 18 is fixedly sleeved on the rotating shaft. The fixed end of the electric telescopic rod 17 is rotatably arranged on the side wall of the support plate 3 through a shaft, and the movable end of the electric telescopic rod 17 is rotatably connected to the end of the connecting plate 18 through a shaft. When the electric telescopic rod 17 expands and contracts, it can pull or push the connecting plate 18, and the connecting plate 18 drives the rotating shaft to rotate forward and backward. Then the rotating shaft drives the connecting seat 8 and the support plate 9 to adjust the pitching angle, so as to change the pitching angle of the output pipe 4 when it is distributed on the support plate 9, that is, to adjust the spraying distance of the concrete when it is distributed.

[0023] The connecting member 14 includes a stud 19 and a nut 20.

By loosening the nut 20, the stud 19 can be selected from the second clamping seat 22, and thus the clamping ring 10 can be opened to remove the output pipe 4.

[0024] A support plate 23 is provided on the side wall of the mobile vehicle 1, and an electric telescopic rod 24 is provided on the support plate 23. The bottom end of the electric telescopic rod 24 slidably penetrates through the support plate 23 and extends out, and a backing plate 25 is provided at the movable end of the electric telescopic rod 24. When the electric telescopic rod 24 extends out, the backing plate 25 will support the mobile vehicle 1 to increase the stability during concrete distribution.

[0025] During specific use, the height of the output pipe 4 can be adjusted through the hydraulic cylinder 2, and the driving motor 5 rotates forward and backward to adjust the orientation of the output pipe 4. At the same time, the electric telescopic rod 17 expands and contracts, which can pull or push the connecting plate 18. The connecting plate 18 drives the rotating shaft to rotate forward and backward, and then the rotating shaft drives the connecting seat 8 and the support plate 9 to adjust the pitching angle, so as to change the pitching angle of the output pipe 4 when it is distributed on the support plate 9, that is, to adjust the spraying distance of the concrete when it is distributed. The concrete pump 15 pumps the concrete into the conveying pipe 16, and the conveying pipe 16 sends it into the output pipe 4 for distribution.

[0026] By loosening the nut 20, the stud 19 can be selected from the second clamping seat 22, and thus the clamping ring 10 can be opened to remove the output pipe 4.

[0027] When the electric telescopic rod 24 extends out, the backing plate 25 will support the mobile vehicle 1 to increase the stability during concrete distribution.

[0028] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
