[0043] By setting up the transmission assembly 7 and cooperating with each other in the transmission assembly 7, a relatively large volume of waste can be quickly transferred, thereby improving the transfer efficiency, which not only saves the transfer time, but also saves time and labor.
[0044] In this embodiment, the transmission assembly 7 also includes a fixed cylinder 706 arranged below the connecting cylinder 704, the back side of the fixed cylinder 706 is fixedly connected to the front side of the fixed vertical plate 701, a movable circular groove 707 is provided on the front side of the fixed cylinder 706, and a connecting short column 708 is rotatably connected inside the movable circular groove 707. Part of the outer wall of the connecting short column 708 is located on the front side of the fixed cylinder 706, and a transmission handle 709 is provided on the front side of the connecting short column 708.

[0048] In this embodiment, the transmission assembly 7 further includes a transmission half gear 712 fixedly connected to the bottom surface of the transmission handle 709 .
[0049] By setting the transmission half gear 712, the setting of the transmission half gear 712 is convenient for using waste materials of different sizes, volumes and shapes.
[0050] The working principle of the present invention is: a steel plate waste collection and processing device, before use, the staff first tilts the right side of the first collection plate 1 and the second collection plate 3 to install them at the appropriate position on the punch press, when the staff cleans the waste on the punch press, the waste is placed in the first collection slot 2, and the transmission motor 703 is started. When the transmission motor 703 rotates, the transmission disc 705 is driven to rotate through the transmission motor 703 and the connecting column 704, and the transmission disc 610 rotates to drive the transmission rod 711 to move. Under the restriction of the transmission slot 710, the transmission rod 711 moves and drives the connecting short column 708 to move in the movable circle through the transmission disc 705. The first collecting trough 2 is rotated in the groove 707, so that the transmission handle 709 swings, and then the transmission handle 709 makes a reciprocating motion in the left and right directions, so that the waste in the first collecting trough 2 is pushed to the left side of the first collecting plate 1 through the transmission half gear 712, and then the waste in the first collecting trough 2 is continuously pushed to the left side of the first collecting plate 1. Since the first collecting plate 1 and the second collecting plate 3 are installed at an angle, the transmission plate gear 712 cooperates with gravity to slide the waste in the first collecting trough 2 to the left side of the first collecting plate 1, and the staff guarding the left side of the first collecting plate 1 can quickly collect, stack and stack the waste pushed in front of them;
[0051] When the waste is pushed into the first collecting trough 2, when a larger volume of waste slides to the dividing square plate 602, a force is applied to the dividing square plate 602 under the action of the weight of the larger volume of waste, and a force is applied to the return spring 606 through the dividing square plate 602 to compress it, and the dividing square plate 602 rotates on the rotating circular rod 604 through the rotating circular groove 603, so that the dividing square plate 602 rotates downward, and the triangular limit plate 607 will limit the rotation range of the dividing square plate 602, so that the larger volume of waste slides into the second collecting trough 5 through the rotation of the dividing square plate 602, and under the mutual cooperation of the second collecting plate 3 and gravity, the larger volume of waste in the second collecting trough 5 slides to the left side of the second collecting plate 3, and the staff guarding the left side of the second collecting plate 3 can quickly collect, stack and stack the larger volume of waste pushed in front of them, and the dividing square plate 602 will be reset to a distant position under the action of the rebound force of the return spring 606, waiting to be used next time.
[0052] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
