A U-shaped plate 11 is provided in the middle of the outer wall of the guide tube 8. The inside of the U-shaped plate 11 is movably connected with a movable bolt 12. The right end of the U-shaped plate 11 is fixedly connected to the second fixing rod 10. The right end of the second fixing rod 10 is movably connected to the first fixing rod 9. The front and rear ends of the first fixing rod 9 are fixedly connected to the inner wall of the U-shaped bracket 2. The right end of the L-shaped bottom plate 1 is fixedly connected to the electric push rod 13. The left end of the driving shaft of the electric push rod 13 is fixedly connected to the third fixing rod 14. The front and rear ends of the third fixing rod 14 are rotatably connected to the connecting bar 15. The left end of the connecting bar 15 is rotatably connected to the left end of the outer wall of the transmission tube 3.

[0024] Specifically, starting the electric push rod 13 drives the third fixed rod 14 to move forward and backward, and the left side of the connecting bar 15 movably connected to the third fixed rod 14 receives a rightward thrust, and the right side of the connecting bar 15 is rotated and connected to the outer wall of the transmission pipe 3. Therefore, when the left end of the connecting bar 15 receives a thrust, the right side of the connecting bar 15 will tilt and lift the left side of the transmission pipe 3. In addition, the first fixed rod 9, the second fixed rod 10, the movable bolt 12, the guide pipe 8 and the U-shaped bracket 2 constitute a parallelogram structure. Under this structure, the guide pipe 8 can always be kept vertically downward. In addition, a plurality of circular holes are provided on the U-shaped plate 11, and the guide pipe 8 and the U-shaped plate 11 are connected by the movable bolt 12. Therefore, the angle of the guide pipe 8 can be adjusted by changing the position of the movable bolt 12, thereby driving the angle of the discharge pipe 7 inside the guide pipe 8 to be adjusted. Starting the first motor 4 drives the rotating shaft 5 and the spiral blade 6 fixedly connected to the surface of the rotating shaft 5 to rotate, so that the concrete entering from the right side of the upper end of the transmission pipe 3 can be discharged from the discharge pipe 7 for pouring.

[0025] A connecting hose 16 is fixedly connected to the right side of the upper end of the transmission pipe 3, a fixed plate 17 is fixedly connected to the top of the U-shaped bracket 2, a mixing box 18 is fixedly connected to the middle part of the fixed plate 17, a second motor 19 is fixedly connected to the middle part of the upper end of the mixing box 18, a feed hopper 20 is provided on the left side of the upper end of the mixing box 18, the bottom end of the mixing box 18 is fixedly connected to the upper right end of the connecting hose 16, a mixing shaft 21 is rotatably connected to the middle part of the upper end of the inner wall of the mixing box 18, the upper end of the mixing shaft 21 is fixedly connected to the bottom end of the drive shaft of the second motor 19, a scraper 22 is fixedly connected to the upper side of the outer wall of the mixing shaft 21, and a number of mixing rods 23 are fixedly connected to the middle part of the outer wall of the mixing shaft 21.

[0026] Specifically, concrete, water and other casting materials are poured into the interior of the mixing box 18 from the feed hopper 20, and the second motor 19 is started to drive the stirring shaft 21 to rotate. The stirring shaft 21 fixedly connected to the stirring shaft 21 stirs the concrete. At the same time, the scraper 22 fixedly connected to the stirring shaft 21 scrapes the inner wall of the mixing box 18 to prevent the concrete from solidifying on the inner wall of the mixing box 18. A valve is provided at the bottom end of the mixing box 18. After the mixing is completed, the valve is opened to allow the concrete to enter the interior of the transmission pipe 3 through the connecting hose 16.

[0027] The front and rear ends of the L-shaped bottom plate 1 are both threadedly connected with screw rods 24 , the bottom end of the screw rods 24 is fixedly connected with a fixing block 25 , and universal wheels 26 are provided at the four corners of the bottom end of the L-shaped bottom plate 1 .

[0028] Specifically, the universal wheels 26 provided at the four corners of the bottom of the L-shaped base plate 1 allow the entire device to move flexibly, making it convenient for workers to operate. When the device arrives at the location where pouring operations are required, the rotating screw 24 drives the fixed block 25 to rotate and descend until it contacts and is fixed to the ground.

[0029] Working principle: When in use, cement and other casting materials are poured into the interior of the mixing box 18 from the feed hopper 20, and the second motor 19 is started to drive the stirring shaft 21 to rotate. The stirring shaft 21 drives the stirring rod 23 to stir the casting materials inside the mixing box 18, and the electric push rod 13 is started to drive the third fixed rod 14 to move forward. The third fixed rod 14 cooperates with the connecting bar 15 to drive the left side of the transmission pipe 3 to lift upward. While the transmission pipe 3 is lifted upward, the guide pipe 8 always remains vertically downward under the cooperation of the first fixed rod 9, the second fixed rod 10, the U-shaped plate 11 and the movable bolt 12. At the same time, a circular hole is provided on the U-shaped plate 11. By changing the position of the movable bolt 12 in the circular hole, the guide pipe 8 can be adjusted to a certain angle. After mixing, the concrete enters the interior of the transmission pipe 3 through the connecting hose 16, and the first motor 4 is started. The first motor 4 drives the rotating shaft 5 and the spiral blade 6 fixed on the surface of the rotating shaft 5 to rotate. The spiral blade 6 rotates to transfer the concrete to the side where the discharge pipe 7 is located and flows out from the discharge pipe 7 for bridge casting.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
