In some water conservancy and hydropower construction projects, feeding devices are required to provide high efficiency.

[0003] A feeding device for water conservancy and hydropower construction projects described in the prior art includes a base, a front lifting rod is arranged on the front side of the top end of the base, a rear lifting rod is arranged on the rear side of the front lifting rod, the front lifting rod and the rear lifting rod have the same width, the top ends of the front lifting rod and the rear lifting rod are hinged with side plates, the side plates on both sides are connected to each other through roller shafts and bearing structures, and a connecting rod is arranged at the front end of the side plate, and a driving motor is installed on one side of the side plate.

[0032] The following describes an embodiment of the present invention based on its overall structure. Example

[0033] See also Figure 1-6 As shown, the feeding method for water conservancy and hydropower construction includes the following steps:

[0034] Step 1: Material transportation: Feed the materials for water conservancy and hydropower construction into the installation shell 1 through the feed pipe 108, so that the materials are located at the front end of the push plate 402 in the push assembly 4.

The turntable 406 reciprocates the push plate 402 through two connecting rods. The push plate 402 pushes the entered materials to move to the retaining groove 3, and the first conveyor belt 102 delivers the materials to the second conveyor belt 2 to complete the feeding;

[0035] Step 2: Cleaning: When the turntable 406 rotates, the rotating shaft 409 passing through the center drives the bidirectional screw 501 in the cleaning assembly 5 to rotate through the chain drive, so that the two moving blocks 502 drive the cleaning brush 5031 to move back and forth under the action of the limiting rod 504, and the moving cleaning brush 5031 cleans the gaps between the protrusions on the first conveyor belt 102, and the cleaned attached materials fall into the storage box 7 below;

The ends of the two connecting blocks 105 are fixedly connected to the outer wall of the control box 104. A reinforcing block 107 is fixedly connected to the top of one connecting block 105 on the top of the outer wall of the placing box 106.

At the end of the feeding, the storage box 7 is pulled out of the installation shell 1 by the staff, and the materials collected in the storage box 7 are poured onto the first conveyor belt 102;

[0043] Therefore, the present application can avoid affecting the movement of the push plate 402 when feeding fluid materials such as stone and sand. At the same time, when the push plate 402 reciprocates, it can drive the cleaning brush 5031 to move back and forth to clean the materials attached to the protrusions on the conveyor belt, thereby ensuring normal transportation during subsequent steel pipe feeding.
