[0021] Through the above technical solution, during the use of the device, the two groups of driving mechanisms can be used to make the two groups of crushing rollers 3 rotate in opposite directions, so as to crush the waste metal. During the crushing process, the waste chips and dust generated can be sprayed with air flow by the fan 8, and the air flow can be redirected in cooperation with the air jet cylinder 11 and the swing-back mechanism to be evenly sprayed in the crushing box 2, so as to spray the waste chips and dust into the dust filter bag 19.

[0022] Specifically, the driving mechanism includes a motor 4 fixedly installed on the frame 1, the output end of the motor 4 is fixedly connected with a driving wheel 5, and a conveyor belt 6 is slidably connected to the outer surface of the driving wheel 5.

[0023] Through the above technical solution, during the process of the motor 4 driving the driving wheel 5 to rotate, the driven wheel 7 can be driven through the conveyor belt 6 to rotate itself.

[0024] Specifically, one end of the inner side of the conveyor belt 6 away from the driving wheel 5 is slidably connected with a driven wheel 7, and the center of the driven wheel 7 is fixedly connected with one end of the crushing roller 3.

[0025] Through the above technical solution, one end of the crushing roller 3 is connected to the center of the driven wheel 7, and the other end is rotatably connected to the inner surface of the crushing box 2.

[0026] Specifically, the swing-back mechanism includes a motor 13 fixedly installed on the fixing frame 9, and the output end of the motor 13 is fixedly connected with a lower rotating disk 14.

[0027] Through the above technical solution, during the rotation of the lower rotating disk 14, the lower disk shaft 15 on its surface will be driven to make a synchronous circular motion.

[0028] Specifically, the outer surface of the lower rotating disk 14 is fixedly connected with the lower disk shaft 15 , and the outer surface of the lower disk shaft 15 is rotatably connected with the guide swing bar 16 .

[0029] Through the above technical solution, the guide swing bar 16 plays a supporting role, and the upper disc 17 is rotated and adjusted to a certain angle through the upper disc shaft 18.

[0030] Specifically, an upper rotating disk 17 is fixedly sleeved on the outer surface of the rotating shaft 10 , an upper disk shaft 18 is fixedly penetrated on the inner side of the upper rotating disk 17 , and an outer surface of the upper disk shaft 18 is rotatably connected to an end of the guide swing bar 16 away from the lower disk shaft 15 .

[0031] Through the above technical solution, the upper rotating disk 17 will drive the rotating shaft 10 to rotate synchronously during the process of rotating back and forth within a certain angle, and the jet cylinder 11 will repeatedly adjust the jet direction as the rotating shaft 10 rotates.

[0032] Working principle: In the process of crushing scrap metal, the device first turns on the motor 4 to drive the driving wheel 5 to rotate, and the driven wheel 7 can be linked to rotate synchronously through the conveyor belt 6. In this process, the two sets of crushing rollers 3 can rotate in opposite directions, and the scrap metal is put into the crushing box 2. The rotating crushing rollers 3 can crush the scrap metal. After the crushing, the scrap metal falls through the frame 1. The scrap metal will produce a certain amount of waste chips and dust during the crushing process. Considering that the chips and dust floating in the air will cause health hazards to the staff, the fan 8 can be turned on at this time to flow the air into the jet cylinder 11 through the corrugated hose 12, and the jet cylinder 11 will spray air into the crushing box 2. At the same time, the motor 13 is turned on to drive the lower rotating disk 14 to rotate, and then the linkage The lower disk shaft 15 makes a circular motion, during which the lower end of the guide swing bar 16 rotates along the lower disk shaft 15, while the top end rotates along the upper disk shaft 18, and the upper disk 17 is driven by the upper disk shaft 18, so that the upper disk 17 rotates back and forth at a certain angle, thereby linking the rotating shaft 10 to rotate synchronously, that is, the jet tube 11 repeatedly deflects at a certain angle to spray the airflow relatively evenly. During this process, the corrugated hose 12 will undergo a certain degree of stretching deformation to cooperate with the adjustment of the position of the jet tube 11. At this time, the airflow containing waste chips and dust flows toward the dust filter bag 19, and the dust filter bag 19 filters and collects the waste chips and dust, which can effectively reduce the floating of waste chips and dust, change the working environment, and improve the environmental protection effect.

[0033] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
