A second rectangular hole 711 is symmetrically provided on the upper surface of the rotating plate 710. A movable block 712 is slidably connected to the hole wall of the second rectangular hole 711. A first protruding column 713 is fixedly connected to the lower surface of the movable block 712. A mounting groove 714, a rectangular groove 715 and a circular groove 716 are provided on the hole wall of the second rectangular hole 711.

A transmission gear 718 is symmetrically meshed with the outer side of the first rack column 717. A second rack column 719 is meshed with the outer side of the transmission gear 718. The column 719 is slidably connected to the wall of the installation groove 714, the wall of the circular groove 716 is fixedly connected to a second spring, one end of the second spring away from the wall of the rectangular groove 715 is fixedly connected to the movable block 712, the surface of the second rack column 719 is symmetrically provided with column grooves 720, the wall of the column groove 720 is slidably connected to a connecting block 721, the surface of the connecting block 721 is symmetrically fixedly connected to a third spring 722, one end of the two third springs 722 away from the connecting block 721 is respectively fixedly connected to the two wall of the column grooves 720, the surface of the connecting block 721 is located above the two third springs 722 and is fixedly connected to a rectangular plate 723, and one end of the upper surface of the rectangular plate 723 away from the connecting block 721 is symmetrically rotatably connected to a second convex column 724; It should be noted that the first motor 811 is started, driving the first bevel gear 817 to rotate, and then driving the second rotating sleeve 818 to rotate, which is driven by the transmission column 8110, driving the worm 8111 to rotate, and then driving the worm wheel 8112 to rotate, and the lifting sleeve 74 is adjusted to move in the direction close to the connecting plate 15. Since the rotating column 71 and the rotating plate 710 are rotatably connected through a one-way bearing, when the lifting sleeve 74 moves downward, the convex block 73 cooperates with the spiral groove 72 to drive the rotating column 71 to rotate. The rotation of the rotating column 71 can drive the rotating plate 710 to rotate, thereby loading the unsheared waste steel plates and unloading the sheared waste steel plates; Specifically, as the transmission column 8110 continues to rotate, the worm wheel 8112 will also continue to rotate. After the worm wheel 8112 separates from the rack plate 75, it will mesh with the first rack 78, driving the first rack 78 to move toward the direction close to the rack plate 75. Relative sliding occurs between the first rack 78 and the connecting rod 77, and the connecting spring 79 is compressed. Thereafter, the worm wheel 8112 rotates again, and the first rack 78 and the worm wheel 8112 are in a state of continuous meshing, separation, and re-meshing, so that the lifting sleeve 74 After being adjusted, it is in a stable state; after completing the shearing process of the scrap steel plate, the first motor 811 drives the first bevel gear 817 to rotate in the opposite direction, and the worm gear 8112 also rotates in the opposite direction, driving the first rack 78 to move in the direction away from the rack plate 75, and the connecting spring 79 is stretched. Then, the worm gear 8112 will mesh with the rack plate 75, driving the lifting sleeve 74 to move in the direction away from the connecting plate 15 until it meshes with the other first rack 78. The first rack 78 and the worm gear 8112 are in a The state of continuous meshing, separation, and re-meshing. During this process, the relative movement between the protrusion 73 and the spiral groove 72 will not drive the rotating column 71 to rotate, and then the lifting sleeve 74 is repeatedly adjusted to move in the direction close to the connecting plate 15 and away from the connecting plate 15. During the rotation process of the rotating plate 710, its surface contacts the surface of the waste steel plate that has been sheared on the surface of the multiple balls 2, pushing the waste steel plate to pass between the horizontal column 3 and the bottom plate 1, and the side of the waste steel plate that has not been sheared and placed on the upper surface of the rotating plate 710 can contact the surface of the horizontal column 3. The rotating plate 710 and the waste steel plate that has not been sheared rotate relative to each other until it is separated from the waste steel plate. The waste steel plate will contact the surfaces of the multiple balls 2 and the surface of the L-shaped plate 11 to complete the placement and positioning, assist in the unloading of the waste steel plate that has been sheared, and the unloading process of the waste steel plate that has not been sheared. The loading process and the unloading process are carried out simultaneously, shortening the time required for the entire processing process, thereby improving the efficiency of the shearing process; In the process of rotating the rotating column 71 being adjusted and rotated to drive the rotating plate 710 to rotate, the first protruding column 713 contacts the side of the bottom plate 1, so that the movable block 712 can slide relative to the second rectangular hole 711, and the first rack column 717 moves with the movable block 712, and is driven by the transmission gear 718. The second rack column 719 moves with the first rack column 717, and the movement direction is opposite. The two second protruding columns 724 move with the second rack column 719, driving the unsheared waste steel plate to move in the direction away from the rotating column 71 until the waste steel plate contacts the surface of the L-shaped plate 11. , by utilizing the elasticity and scalability of the third spring 722, the unsheared scrap steel plates of different sizes can be stably placed and positioned, one of the side surfaces of the unsheared scrap steel plates will contact the surface of the horizontal column 3, and then the rotating plate 710 and the unsheared scrap steel plates will rotate relative to each other until they are separated, completing the loading. The unsheared scrap steel plates of different sizes can be placed and positioned, and when switching the unsheared scrap steel plates of different sizes for shearing, there is no need to stop the equipment for adjustment, which can reduce the equipment downtime during the processing, thereby further improving the efficiency of the shearing process.
