The device includes a crushing mechanism, a sorting mechanism below the crushing mechanism, a housing, an inlet above the housing, a conveyor belt below the inlet, an electromagnet inside the conveyor belt, a motor A above the electromagnet, a turntable below the motor A, and multiple stirring rods arranged in a ring at equal intervals below the turntable. Below the conveyor belt is a box containing two symmetrically arranged collection boxes. A baffle is located above the right-hand collection box. A rotating shaft is located at the front of the box, with a roller in the middle. A motor B is located on the left side of the rotating shaft. Two return springs are symmetrically arranged at the rear of the box. This device can effectively process waste templates.

[0004] However, the device still has some problems. In actual use, the conveyor belt in the device is prone to loosening and slipping after a long period of use. It cannot quickly adjust the tension of the conveyor belt according to actual needs, resulting in ineffective and unstable transportation. Therefore, we propose an engineering construction waste treatment device to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] like Figure 1-4As shown, an embodiment of this utility model discloses an engineering construction waste treatment device, comprising a housing 1, two transmission rollers 2 rotatably connected between the inner walls of the two sides of the housing 1, and a common conveyor belt 3 drivingly connected to the two transmission rollers 2. A first motor 4 is fixedly connected to the front side of the housing 1. The end of one of the two transmission rollers 2 extends outside the housing 1 and is fixedly connected to the output shaft of the first motor 4. A lead screw 19 is rotatably connected to the inner walls of both sides of the housing 1. The end of one of the lead screws 19 extends outside the housing 1 and is welded with a knob 5. A moving block 6 is threadedly connected to the lead screw 19. An inclined hinge rod 7 is rotatably connected to one side of the moving block 6. The ends of the two hinge rods 7 are hinged to the same U-shaped plate 8. The inner walls of the U-shaped plate 8 are connected to the same U-shaped plate 8. A pressure roller 9 is rotatably connected between the walls. The bottom of the pressure roller 9 rolls in contact with the inner bottom of the conveyor belt 3. A square rod 10 is welded between the inner walls of the two sides of the housing 1. The square rod 10 is slidably connected to the moving block 6. Two T-shaped rods 11 are welded to the bottom of the square rod 10. The T-shaped rods 11 are slidably connected to the U-shaped plate 8. Rotating the knob 5 causes the corresponding moving block 6 to move through the lead screw 19. The moving block 6 slides on the square rod 10 and presses the hinge rod 7. Under the pressure, the hinge rod 7 moves and rotates. The hinge rod 7 drives the U-shaped plate 8 to move downward. The U-shaped plate 8 drives the pressure roller 9 to press the conveyor belt 3, making the conveyor belt 3 taut. The tension of the conveyor belt 3 can be adjusted as needed to prevent slippage during conveying and ensure smooth feeding.

[0026] In some embodiments, the ends of two lead screws 19 that are close to each other are fixedly connected, and the threads of the two lead screws 19 are turned in opposite directions.

[0027] In some embodiments, a feed inlet 12 is provided on the top inner wall of the housing 1, and a guide plate 13 is fixedly connected to one side inner wall of the feed inlet 12. The guide plate 13 serves to guide the flow.

[0028] In some embodiments, a second motor 14 is fixedly connected to the top of the housing 1, and the output shaft of the second motor 14 extends into the housing 1 and is fixedly connected to a connecting plate 15.

[0029] In some embodiments, a plurality of stirring rods 16 are fixedly connected to the bottom of the connecting plate 15, and an electromagnet 17 is provided on the rear inner wall of the housing 1. The stirring rods 16 serve to stir.

[0030] In some embodiments, a sorting mechanism 18 is provided below the housing 1.

[0031] The working principle or structural principle is as follows: During use, the conveyor belt 3 transports the crushing template that enters from the feed inlet 12 to the left. During this movement, the second motor 14 drives the stirring rod 16 via the connecting plate 15 to agitate the crushing template. This causes the iron nails in the template to adhere to the surface of the conveyor belt 3 under the attraction of the electromagnet 17. The crushed template then falls into the sorting mechanism 18 due to gravity while being transported by the conveyor belt 3. The iron nails, attracted by the electromagnet 17, move to the right from the bottom of the conveyor belt 3. Since the electromagnet 17 is located on the left side inside the conveyor belt 3, the iron nails move to the right... During movement, the attraction of the electromagnet 17 to the nails will gradually decrease until they fall into the sorting mechanism 18 located on the right. When the tension of the conveyor belt 3 needs to be adjusted after long-term use, the knob 5 is turned. The knob 5 drives the corresponding moving block 6 to move through the lead screw 19. The moving block 6 slides on the square rod 10 and squeezes the hinge rod 7. Under the action of the squeezing force, the hinge rod 7 moves and rotates. The hinge rod 7 drives the U-shaped plate 8 to move downward. The U-shaped plate 8 drives the pressure roller 9 to squeeze the conveyor belt 3, making the conveyor belt 3 taut. Thus, the tension of the conveyor belt 3 can be adjusted as needed to prevent the conveyor belt 3 from slipping during conveying and to ensure smooth feeding.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
