[0035] When the construction waste needs to be processed, the construction waste is firstly transmitted through the conveying platform 51. The conveying platform 51 starts the motor 5421 while transmitting the construction waste. After the motor 5421 is started, the transmission plate 5423 rotates, and then the two crawlers 5424 drive the two second transmission plates 5425 to rotate synchronously with the transmission plate rotating rod 5426. The two transmission plate rotating rods 5426 rotate to drive the rotating rod 5427 on the inner wall of the U-shaped frame 5422 to rotate, so that the push-pull rods 5428 on the inner side of the two sets of rotating rods 5427 perform reciprocating push-pull motions, so that the two V-shaped connecting rods 5429 are pulled to reciprocate on the inner wall of the hinge block 5414, so that the two crushing components 542 perform reciprocating inward and outward movements, and the waste transmitted by the conveying platform 51 is preliminarily processed to break its surface. After the waste is preliminarily processed, the waste falls to the inner wall of the separation bin 3 through the inclined slide plate 5417;

[0036] At this time, the turntable motor 343 and the magnetic attraction plate 3415 are started. The magnetic attraction plate 3415 is started to generate a magnetic attraction force on one side of the inner wall of the separation bin shell 31. The turntable motor 343 starts the transmission turntable 344 to drive the turntable rotating rod 345 to rotate on the inner wall of the elliptical slide plate 346, and then the elliptical slide plate 346 and the crushing plate push-pull stem 347 are used to make the separation and crushing plate 348 push and pull back and forth on the inner wall of the separation bin shell 31, and then the waste falling into the inner wall of the separation bin shell 31 is crushed again, so that the steel bars or other metal materials mixed therein are attracted to the magnetic attraction plate 3415 on one side of the inner wall of the separation bin shell 31 through the magnetic attraction plate 3415, and the crushed waste falls to the inner wall of the crusher 2 through the bottom of the separation bin shell 31, and is crushed by the crusher 2.

[0037] like Fig.10As shown, a transmission vertical plate 349 is fixedly connected to the right side of the rear side of the top of the control frame plate 341, a transmission vertical plate slot 3410 is opened on one side of the transmission vertical plate 349, a screw motor placement bin 3411 is fixedly connected to the rear side of the left side of the transmission vertical plate 349, a screw motor 3412 is fixedly connected to the inner wall of the screw motor placement bin 3411, an output end of the screw motor 3412 extends to the front side of the outer wall of the screw motor placement bin 3411 and is fixedly connected to a screw 3413, a magnetic plate transmission rod 3414 is threadedly connected to the outer wall of the screw 3413, the right side of the magnetic plate transmission rod 3414 extends to the right side of the transmission vertical plate 349 through the transmission vertical plate slot 3410 and is fixedly connected to a magnetic plate 3415, and the outer wall of the magnetic plate 3415 is slidably connected to the inner wall of the separation bin slot 33 opened on the rear side of the separation bin shell 31;

[0038] When separating the separated steel bars or other metal materials from the inner wall of the separation bin shell 31, first, start the screw motor 3412. The start of the screw motor 3412 will drive the transmission screw 3413 to rotate, and then the magnetic plate transmission rod 3414 will slide on the inner wall of the transmission vertical plate slide 3410, pulling the magnetic plate 3415 out from the inner wall of the separation bin shell 31 and aligning it with the top of the feed port of the steel bar collection bin 4. Then, the magnetic plate 3415 stops working, and the steel bars or other metal materials attached to the magnetic plate 3415 will fall on the inner wall of the steel bar collection bin 4. In this way, metal materials can be effectively separated from non-metallic materials, thereby improving the recycling rate of waste materials. In addition, the design of the device also takes into account the convenience and safety of operation to ensure the safety of workers during the separation process. The entire separation process is precisely controlled by the control system to ensure separation efficiency and quality.

[0039] Working principle of the present invention: when construction waste needs to be processed, the construction waste is first transmitted through the conveying platform 51. The conveying platform 51 starts the motor 5421 while transmitting the construction waste. After the motor 5421 is started, the transmission plate 5423 is driven to rotate, so that the two crawlers 5424 drive the two second transmission plates 5425 to rotate synchronously with the transmission plate rotating rod 5426. The two transmission plate rotating rods 5426 rotate to drive the rotating rod 5427 on the inner wall of the U-shaped frame 5422 to rotate, so that the push-pull rods 5428 on the inner sides of the two sets of rotating rods 5427 perform reciprocating push-pull motions, so that the two V-shaped connecting rods 5429 are pulled to reciprocate on the inner wall of the hinge block 5414, so that the two crushing components 542 perform reciprocating inward and outward movements, and the waste transmitted by the conveying platform 51 is preliminarily processed to break its surface, and the waste is crushed. After the preliminary treatment, the waste falls to the inner wall of the separation bin 3 through the inclined slide plate 5417. At this time, the turntable motor 343 and the magnetic suction plate 3415 are started. The magnetic suction plate 3415 is started to generate a magnetic suction force on one side of the inner wall of the separation bin shell 31. The turntable motor 343 starts the transmission turntable 344 to drive the turntable rotating rod 345 to rotate on the inner wall of the elliptical slide plate 346, and then the elliptical slide plate 346 and the crushing plate push-pull stem 347 are used to make the separation and crushing plate 348 push and pull back and forth on the inner wall of the separation bin shell 31, so as to crush the waste falling into the inner wall of the separation bin shell 31 again, so that the steel bars or other metal materials mixed therein are attracted to the side of the magnetic suction plate 3415 on the inner wall of the separation bin shell 31 through the magnetic suction plate 3415, and the crushed waste falls to the inner wall of the crusher 2 through the bottom of the separation bin shell 31, and is crushed by the crusher 2.

[0040] When separating the separated steel bars or other metal materials from the inner wall of the separation bin shell 31, first, start the screw motor 3412. The start of the screw motor 3412 will drive the transmission screw 3413 to rotate, and then the magnetic plate transmission rod 3414 will slide on the inner wall of the transmission vertical plate slide 3410, pulling the magnetic plate 3415 out from the inner wall of the separation bin shell 31 and aligning it with the top of the feed port of the steel bar collection bin 4. Then, the magnetic plate 3415 stops working, and the steel bars or other metal materials attached to the magnetic plate 3415 will fall on the inner wall of the steel bar collection bin 4. In this way, metal materials can be effectively separated from non-metallic materials, thereby improving the recycling rate of waste materials. In addition, the design of the device also takes into account the convenience and safety of operation to ensure the safety of workers during the separation process. The entire separation process is precisely controlled by the control system to ensure separation efficiency and quality.
