[0024] The upper support includes a cross bar 11, a longitudinal bar 12, and an inclined channel 13; the left end of the cross bar 11 is connected to the top of the shaft, and the right end extends towards the center of the shaft; the bottom end of the longitudinal bar 12 is connected to the left end of the cross bar 11; the left end of the inclined channel 13 is connected to the top of the longitudinal bar 12, and the right end is connected to the right end of the cross bar 11;

[0025] The hopper 2 is arranged at the right end of the cross bar 11, and the opening of the hopper 2 is arranged below the inclined channel 13;

[0026] The conveying pipe 3 is connected to the bottom of the hopper 2 at the upper part and extends downward into the lower end of the shaft at the lower part;

[0027] The rotating structure 4 is fixed to the cross bar 11 at the upper end and is connected to the chute 5 at the lower end, and drives the chute 5 to rotate;

[0028] The support frame 6 is connected to the bottom of the chute 5 at the top, and universal wheels 7 are provided at the bottom of the support frame 6.

[0029] When using this device, first, the cross bar 11 is arranged at the upper end of the shaft. The cross bar 11 is connected to the top of the shaft as a fixed foundation. After the longitudinal bar 12 is arranged on the cross bar 11, the inclined channel 13 is then arranged. During operation, the operator directly conveys concrete through the inclined channel 13. The concrete falls from the inclined channel 13 into the hopper 2 and is then conveyed downward through the conveying pipe 3 to the chute 5. The bottom of the chute 5 is aligned with the concrete feeding area. When the position needs to be adjusted, the rotating mechanism 4 is started to drive the chute 5 to rotate to change the construction area. Since the universal wheels 7 are provided on the support frame 6, the support frame 6 continuously supports the chute 5 when following the rotation of the chute 5, ensuring the stability of the device.

In this embodiment, the conveying pipe 3 is divided into multiple vertical pipes 31. During the downward transportation of concrete, it passes through a plurality of buffer inclined sheets 32 for buffering, avoiding excessive impact and preventing the phenomenon of concrete segregation, ensuring the construction quality. More preferably, the vertical pipe 31 can be made of PVC material, which has a relatively small frictional resistance and is also relatively light.

[0031] As shown Figure 2 in the figure, as a preferred embodiment, it further includes a connecting piece 33 and a connecting steel wire 34. The connecting piece 33 is arranged at the connection of two vertical pipes 31. Connecting holes are provided on both the connecting piece 33 and the vertical pipe 31. The connecting steel wire 34 passes through the connecting hole of the connecting piece 33 and the upper vertical pipe 31 and then passes through the connecting hole of the connecting piece 33 and the lower vertical pipe 31 to complete the fixation. In this embodiment, in order to make the connection of multiple vertical pipes 31 more convenient, the connecting piece 33 and the connecting steel wire 34 are provided, which facilitates the disassembly between the vertical pipes 31 and improves the maintenance and replacement efficiency.

When using the rotating structure 4, start the motor at the upper end, use the motor to drive the vertical rod to rotate. Since the vertical rod is fixedly connected to the chute 5, it drives the chute 5 fixedly connected to the inclined rod to rotate, changing the feeding area.

The lower end of the diagonal brace 14 is connected to the inner wall of the shaft, and the upper end is connected to the middle bottom end of the cross bar 11. In this embodiment, the diagonal brace 14 is arranged to be connected to the cross bar 11, improving the stability of the device.

The ground anchor steel plate 8 is fixedly connected to the cross bar 11, and the anchor bars 9 pass through the ground anchor steel plate 8 and are fixed to the top of the shaft. In this embodiment, the ground anchor steel plate 8 and the anchor bars 9 improve the stability of the connection between the cross bar 11 and the shaft.

[0035] As shown Figure 1 in the figure, as a preferred embodiment, the support frame 6 is a triangular support frame. In this embodiment, setting the triangular support frame improves the stability of the device.

[0036] As shown Figure 1 in the figure, as a preferred embodiment, the chute 5 is arranged as a U-shaped groove. In this embodiment, the chute 5 is arranged as a U-shaped groove to prevent the concrete from spilling out of the chute 5 during transportation.
