DETAILED DESCRIPTION

[0019] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0020] See also Figures 1 to 4 The embodiment of the present application provides a processing device for crushing and recycling scrap steel, including a frame 1, two crushing rollers 2 are rotatably connected in the frame 1, feeding inclined plates 3 are arranged on both sides of the frame 1, two arc plates 4 are rotatably connected to the frame 1, the arc plates 4 are arranged in cooperation with the feeding inclined plates 3, a driving mechanism for driving the arc plates 4 to rotate is installed on the frame 1, a cutting frame 5 is slidably connected to the top of the frame 1, a cutting roller 6 is rotatably connected to the cutting frame 5, a linear actuator 7 is installed on the frame 1, and the linear actuator 7 can be an electric cylinder, a ... The output end of the wire actuator 7 is connected to the cutting frame 5, and a rotating drive device 8 is installed on the cutting frame 5. The rotating drive device 8 can be a motor. The output end of the rotating drive device 8 is connected to the cutting roller 6 through a belt drive assembly. A U-shaped pressure cylinder 9 is installed on the frame 1. Pressure plates 10 are connected to the sliding seals on both sides of the U-shaped pressure cylinder 9. An input pipe 11 is provided on the U-shaped pressure cylinder 9. The input end of the input pipe 11 is connected to a pressure source. The pressure source can be a pneumatic pump or a hydraulic pump. The pressure plates 10 are located on both sides of the cutting frame 5.

[0021] In this embodiment, the scrap steel slides from the feeding ramp 3 to the top of the two crushing rollers 2 in the frame 1, and then falls and is crushed. The two arc plates 4 can be driven by the driving mechanism to rotate in opposite directions. During rotation, the two arc plates 4 can squeeze the scrap steel accumulated above the crushing rollers 2 toward the middle to a certain extent, thereby playing a role in auxiliary feeding. The rotated arc plates 4 seal the space above the crushing rollers 2 to a certain extent, thereby preventing fragments from splashing. The pressure source can also transmit pressure to the U-shaped pressure cylinder 9 through the input pipe 11, thereby squeezing out the pressure plate 10. After being squeezed out, the two pressure plates 10 abut against the feeding ramp 3, thereby achieving a complete sealing effect on the inside of the frame 1. When cutting large pieces of material, the arc plate 4 rotates to a suitable position to bear the scrap steel that slides into the frame 1. Then the pressure plate 10 is driven down to fix the large piece of scrap steel and to shield and prevent splashing. After fixation, the linear actuator 7 drives the cutting frame 5 to descend, and the rotary drive device 8 on the cutting frame 5 drives the descending cutting roller 6 to rotate rapidly, so that the fixed large piece of scrap steel can be cut. After the cutting is completed, the arc plate 4 is reset, so that the cut small piece of scrap steel falls and is crushed. Then the arc plate 4 rotates to a suitable position again, and the pressure plate 10 rises and then descends, so that the uncut part of the material continues to slide on the arc plate 4 and is fixed, thereby repeating the above process, realizing the integrated cutting and crushing of large pieces of scrap steel and improving practicality.

[0022] In some embodiments, in order to realize the driving rotation of the two arc-shaped plates 4, a driving mechanism is provided, including a gear 12, which is rotatably connected to the frame 1, wherein a gear 2 13 is installed on one of the arc-shaped plates 4, and the gear 1 12 is meshedly connected with the gear 2 13, and a rotation driving device 2 14 is installed on the frame 1, and the rotation driving device 2 14 can be a servo motor, and the output end of the rotation driving device 2 14 is transmission-connected to the gear 12, and the two arc-shaped plates 4 are transmission-connected through a belt transmission assembly.

[0023] In some embodiments, in order to facilitate the cutting of large pieces of scrap steel, a feed groove 15 adapted to the cutting roller 6 is provided on the curved plate 4. When the curved plate 4 squeezes small pieces of scrap steel, the feed groove 15 is not exposed. Only when carrying large pieces of material, the feed groove 15 is exposed to cooperate with the cutting roller 6 to split the scrap steel, thereby preventing small pieces of material from entering the feed groove 15.

[0024] In some embodiments, in order to ensure that the scrap steel fragments falling into the frame 1 can accurately fall to the crushing position between the two crushing rollers 2, guide plates 16 are installed on both sides of the frame 1.

[0025] In some embodiments, in order to achieve the purpose of sliding and locking the cutting frame 5 on the frame 1, a plurality of slots 17 are provided on the top of the frame 1, and blocks 18 corresponding to the slots 17 are installed on the cutting frame 5, and the blocks 18 are slidably locked in the slots 17.

[0026] In some embodiments, in order to facilitate driving the two crushing rollers 2, meshing gears 19 are installed on the crushing rollers 2, and the two meshing gears 19 are meshed and connected. A rotating drive device 3 20 is installed on the frame 1, and the output end of the rotating drive device 3 20 is meshed and connected with one of the meshing gears 19.
