[0022] Reference Figure 1-2The bottom of the extrusion plate 8 is fixedly connected with a connecting shaft 11 near the front and back, and the connecting shaft 11 is connected to the inner side of the shell 1 by a bearing. A fixing plate 9 is provided on the side of the extrusion plate 8 away from the connecting piece 7, and the front and back of the fixing plate 9 are fixedly connected to the inner side of the shell 1. The extrusion plate 8 and the fixing plate 9 are fixedly connected with a wear-resistant plate 10 near the center of the two, which is beneficial to improve the wear resistance of the extrusion plate 8 and the fixing plate 9. When the extrusion plate 8 and the fixing plate 9 are extruded, some horizontal steel bars will exist in the waste, which will cause damage to the extrusion plate 8 and the fixing plate 9. The wear-resistant plate 10 can play a certain protective role for the extrusion plate 8 and the fixing plate 9. A stopper 13 is fixedly connected to the top of the screening plate 12 away from the connecting piece 7. The stopper 13 can prevent the steel bars on the screening plate 12 from detaching when the screening plate 12 moves, which is beneficial to further improve the stability during use.

[0023] Reference Figure 2-4 The side of the screening plate 12 away from the stopper 13 is fixedly connected with the second electric telescopic cylinder 16, and the side of the second electric telescopic cylinder 16 away from the screening plate 12 is fixedly connected to the inner side of the shell 1, and the first partition plate 17 and the second partition plate 18 are fixedly connected to the inner side of the shell 1.

[0024] The method of using the utility model is as follows: the user can put the construction waste into the feed hopper 2, and the construction waste enters between the extrusion plate 8 and the fixed plate 9 through the feed hopper 2, and the first electric telescopic cylinder 6 pushes the extrusion plate 8 through the connecting piece 7, so that the extrusion plate 8 squeezes the waste, so that part of the waste enters the first crushing roller 14 and the second crushing roller 15 through the screening plate 12, and is further crushed by the first crushing roller 14 and the second crushing roller 15, while part of the waste containing steel bars will be removed from the discharge port 4 during the pressing of the extrusion plate 8 and the fixed plate 9, and the waste outside the steel bars will be removed from the discharge port 4.

[0025] At the same time, this continuous pressing method can also change the direction of the steel bars, so that the direction of the steel bars is generally distributed in a front-to-back state. This state will cause the steel bars to be blocked by the screening plate 12 when they fall on the screening plate 12, and will not fall on the first crushing roller 14 and the second crushing roller 15. Some shorter steel bars pass through the screening plate 12 and enter the first crushing roller 14 and the second crushing roller 15, and will not have a significant impact on the first crushing roller 14 and the second crushing roller 15.

[0026] The thicker and longer steel bars will be limited by the stopper 13 and pulled to the top of the push block 19 with the movement of the screen plate 12 during the timed pulling of the second electric telescopic cylinder 16 on the screen plate 12, and then the central shaft 24 will be driven to rotate by the first servo motor 20, and the central shaft 24 will drive the second bevel gear 26 to rotate, and the second bevel gear 26 will drive the first bevel gear 25 to rotate, and the first bevel gear 25 will drive the threaded rod 29 to rotate, and then the limiting effect of the limiting rod 27 will make the push block 19 rise, and then through the inclined state of the top of the push block 19, the steel bars on the screen plate 12 are lifted and fall to the side of the first partition plate 17 away from the push block 19, and then leave the interior of the shell 1 through the separation port 3.
