[0022] Example: Reference Figure 1-Figure 4 The construction waste crushing device shown in the figure includes a crushing box 1 and a collecting box 2. Four supporting legs 3 and a discharge hose 4 are fixedly arranged at the bottom of the crushing box 1. The collecting box 2 is located directly below the discharge hose 4. A crushing assembly for crushing construction waste is installed on the crushing box 1. The crushing assembly includes two crushing rollers 6 arranged in the crushing box 1. Rotating holes are opened on the two sides of the crushing box 1 away from each other. A crushing shaft 5 is installed in each two corresponding rotating holes for common rotation. The two crushing rollers 6 are respectively fixedly sleeved on the two crushing shafts 5. A crushing motor 7 is fixedly arranged on the side of the crushing box 1. The output end of the crushing motor 7 is fixedly connected to one end of one of the crushing shafts 5. A connecting gear 17 is fixedly sleeved on the two crushing shafts 5. The two connecting gears 17 are arranged to mesh with each other. The sides of the two supporting legs 3 are fixedly installed together. A U-shaped mounting frame 8 is provided, and a mounting hole is opened on the side of the U-shaped mounting frame 8. A driving shaft 9 is rotatably installed in the mounting hole, one of the crushing shafts 5 is connected to a pulley transmission unit for making the driving shaft 9 rotate synchronously, one end of the driving shaft 9 is fixedly installed with a connecting arm 10, an adjusting sleeve 11 is slidably sleeved on the connecting arm 10, and an adjusting unit for fixing the adjusting sleeve 11 is connected to the connecting arm 10, an eccentric rod 12 is fixedly installed on the side of the adjusting sleeve 11, a connecting ring 13 is fixedly sleeved on the discharge hose 4, a connecting rod 14 is fixedly installed on the side of the connecting ring 13, a U-shaped connecting rod 15 is fixedly installed on the end of the connecting rod 14, and a reciprocating frame 16 is fixedly installed at both ends of the U-shaped connecting rod 15, the eccentric rod 12 is adaptively arranged in the reciprocating frame 16, and a horizontal guide unit is installed on the reciprocating frame 16.

[0023] By means of the above structure, when the crushing motor 7 is started, the two crushing rollers 6 will be driven to rotate towards each other through the crushing shaft 5 and the connecting gear 17 to crush the construction waste. In this process, the rotation of the crushing shaft 5 will drive the driving shaft 9 to rotate synchronously through the pulley transmission unit. The rotation of the driving shaft 9 will drive the eccentric rod 12 to rotate in a circle through the connecting arm 10 and the adjusting sleeve 11. With the cooperation of the horizontal guide unit, the circular rotation of the eccentric rod 12 will drive the reciprocating frame 16 to move back and forth horizontally, and then the discharge hose 4 can be driven to move back and forth together through the U-shaped connecting rod 15, the connecting rod 14 and the connecting ring 13, so that the crushed construction waste can be guided to fall evenly into the collection box 2 for unified collection. There is no need for the staff to frequently move the collection box 2 or use tools to flatten the garbage inside it, which greatly reduces the workload of the staff. It is simple and convenient to use and has good practicality.

[0024] refer to Figure 2 and Figure 3 As shown, the pulley transmission unit includes two transmission pulleys 18 respectively fixedly mounted on the ends of the crushing shaft 5 and the driving shaft 9, and a transmission belt 19 is provided on the two transmission pulleys 18 for tensioning. The advantage of such a setting is that when the crushing shaft 5 rotates, one of the transmission pulleys 18 will be driven to rotate, and under the action of the transmission belt 19, the other transmission pulley 18 will be driven to rotate together, and then the driving shaft 9 can be driven to rotate synchronously, playing the role of synchronous transmission, and no longer needing to set up a separate power device for the driving shaft 9.

[0025] refer to Figure 4 As shown, the adjustment unit includes a fixed plug rod 20, a plug rod sliding hole is provided on the side of the adjustment sleeve 11, and the fixed plug rod 20 is slidably installed in the plug rod sliding hole. A plurality of fixed plug holes are evenly provided on the side of the connecting arm 10, and one end of the fixed plug rod 20 extends into one of the fixed plug holes. A control pull block 21 is fixedly installed on the other end of the fixed plug rod 20, and an elastic reset element is installed on the control pull block 21. The advantage of such a setting is that when the control pull block 21 is moved, the fixed plug rod 20 will be driven to move in or out of the fixed plug hole, thereby fixing or loosening the adjustment sleeve 11. When the adjustment sleeve 11 is in a loosened state, the rotation radius of the eccentric rod 12 can be changed by sliding the adjustment sleeve 11 up and down, thereby achieving the purpose of adjusting the back and forth moving distance of the reciprocating frame 16 and the discharge hose 4, so as to adapt to the collection boxes 2 of different sizes and improve the application range of the device.

[0026] In this embodiment, the elastic reset element includes a reset spring 22 sleeved on the fixed plug rod 20, and the two ends of the reset spring 22 are respectively fixedly mounted on the side of the adjustment sleeve 11 and the control block 21. The advantage of this arrangement is that when the control block 21 is released, the elastic force of the reset spring 22 will pull the control block 21 to automatically reset, and then the fixed plug rod 20 can be automatically inserted into the fixed plug hole, so that the adjustment sleeve 11 is always fixed, which is stable and reliable.

[0027] refer to Figure 1 and Figure 3 As shown, the horizontal guide unit includes two horizontal guide rods 24 fixedly mounted on the side of the support leg 3, and guide blocks 23 are fixedly mounted on the top and bottom of the reciprocating frame 16, and the two guide blocks 23 are respectively slidably sleeved on the two horizontal guide rods 24. The advantage of this arrangement is that, through the coordinated arrangement of the guide blocks 23 and the horizontal guide rods 24, the reciprocating frame 16 can only move back and forth horizontally, thereby ensuring that the eccentric rod 12 and the reciprocating frame 16 will always maintain a linkage state, and the stability is good during operation.

[0028] refer to Figure 1 As shown, the bottom end of the support leg 3 is fixedly provided with a universal self-locking wheel 25. The advantage of such arrangement is that, through the arrangement of the universal self-locking wheel 25, the staff can directly push the device to move, so as to facilitate the mobile transportation of the device.
