The slider (38) is slidably connected to the outside of the guide rod (37). The lead screw of the lead screw motor (36) and the slider (38) are connected by threads. The lifting rod (39) is hinged to the top of the slider (38). The upper end of the lifting rod (39) is hinged to the bottom of the rotating plate (2).

5. A construction material feeding machine according to claim 4, characterized in that, It also includes casters (40), and the bottom of the base box (1) is rotatably connected to casters (40).

6. A construction material feeding machine according to claim 5, characterized in that, It also includes a screw (41) and a pad (42). The bottom of the base box (1) is connected to the screw (41) by a thread, and the lower end of the screw (41) is rotatably connected to the pad (42).

7. A construction material feeding machine according to claim 6, characterized in that, It also includes hooks (43), and hooks (43) are hinged on the skateboard (12).

8. A construction material feeding machine according to claim 7, characterized in that, It also includes a cover plate (44), and the bottom box (1) is open on both the front and rear sides. The bottom box (1) is hinged with a cover plate (44) on both the front and rear sides. The cover plate (44) is used to seal the open parts of the bottom box (1).

9. A construction material feeding machine according to claim 8, characterized in that, It also includes a protective plate (45), and the front and rear sides of the mounting bracket (3) are connected with protective plates (45) for protecting the winding wheel (21).

10. A method of using the construction material feeding machine as described in claim 9, characterized in that, Includes the following steps: S1: Rotate the rotary guide rail (11) so that the rotary guide rail (11) and the guide groove (9) correspond to each other, then insert the locking block (28) into the locking groove (26) and tighten the fastening nut (29) to fix the rotary guide rail (11); S2: Push the sliding frame (4) to the right, causing the electric conveyor roller 1 (5) and electric conveyor roller 2 (14) to move to the right, extending the electric conveyor roller 1 (5) and electric conveyor roller 2 (14) to the right, so that the conveyor belt (15) can transport building materials to the upper floors. S3: Control the screw motor (36) to drive the slider (38) to move to the right. The slider (38) pushes one side of the rotating plate (2) to rotate upward through the lifting rod (39), and controls the mounting frame (3) to lift upward, so that the conveyor belt (15) can transport building materials to the upper floors. S4: Control the output shaft of the servo motor (19) to rotate, drive the winding wheel (21) to rotate, and the winding wheel (21) drives the electric conveyor roller (14) to move to the right through the cable (22), so that the electric conveyor roller (14) can be extended for a second time.
