the rotating motor (19) drives the push rod (18) to rotate for half a circle, the push rod (18) rotates in the sliding rail (16) through the movable block (17) in the rotating process to further synchronously drive the movable rod (14) to swing left and right, so that the movable rod (14) pushes the connecting rod (15) in the swinging process, the top end of the connecting rod (15) moves leftwards to pull the sliding block (12) to stretch;
when the sliding block (12) stretches, holes formed in the sliding block (12) in raw materials in the box body (5) leak out, and the raw materials enter the discharging pipe (10) and are conveyed to a place where materials need to be used;
after the conveying is finished, the box body (5) needs to move downwards for resetting, and the positive and negative motors (8) are started again to rotate so as to drive the screw rods (9) to be meshed with the threaded sleeves (7) to rotate;
the threaded sleeve (7) drives the box body (5) to move downwards until the bottom of the box body (5) is contacted with the top plate (25), and the top plate (25) pushes the connecting block I (22) and the connecting block II (23) to slide towards two sides through the supporting rod (24) under the pressure of the box body (5);
the connecting block I (22) and the connecting block II (23) are abutted against the buffer spring (32) in the process of sliding towards two sides, so that the buffer effect is achieved, and the impact force is reduced when the box body (5) is adjusted downwards.
9. Use of an adjustable feeding device for water conservancy and hydropower construction according to claim 8, wherein the screw rod (9) rotates clockwise when the box body (5) ascends, and the screw rod (9) rotates anticlockwise when the box body (5) descends.
10. The use method of the adjustable feeding device for water conservancy and hydropower construction according to claim 9, wherein the sliding blocks (12) are in a triangular structure, when the sliding blocks (12) are extended and retracted, the box body (5) is hollow, and raw materials flow into the discharging pipe (10).
