[0032] In this embodiment, when it is necessary to process the construction waste, a feed hopper is provided at the upper end of the shell 1, the construction waste is placed from the feed hopper into the shell 1, and then moved along the two guide plates 3 between the two crushing rollers 2, the crushing rollers 2 rotate, thereby crushing the construction waste, and then it will fall onto the sieve plate 8, the crushed construction waste will pass through the sieve plate 8, and some soft plastic waste such as water pipes in the construction waste will not be crushed, so that it will be intercepted by the sieve plate 8, and at the same time, when the first motor 13 is started, the first motor 13 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the half gear 12 to rotate, and when the half gear When the wheel 12 rotates to be meshed with the rack 9, as the half gear 12 rotates, the rack 9 moves upward, the rack 9 drives the sieve plate 8 to move upward, the sieve plate 8 drives the lifting rod 5 and the push ring 6 to move upward, and the first spring 7 is compressed. When the half gear 12 rotates to be separated from the rack 9, under the action of the first spring 7 and gravity, the sieve plate 8 drives the lifting rod 5 and the push ring 6 to move back to their original positions. The operation is repeated in this way, so that the sieve plate 8 vibrates, which can speed up the screening of the crushed waste to prevent blockage. At the same time, the sieve plate 8 is tilted so that the intercepted plastic waste is discharged from the sewage outlet 14 along the sieve plate 8.

[0033] More specifically, the first motor 13 is started to vibrate the screen plate 8, thereby quickly screening the crushed construction waste to prevent clogging, and at the same time, the intercepted plastic waste can be discharged from the sewage outlet 14 along the screen plate 8. The electromagnet 16 is started to adsorb the iron-containing metal in the crushed waste onto the electromagnet 16, thereby separating it.

[0034] See also Figure 1-6 As an implementation method for rotating the crushing roller 2: each crushing roller 2 is fixedly connected to a rotating rod 17, one end of each rotating rod 17 passes through the shell 1 and is fixedly connected to a rotating gear 18, and a first transmission belt structure 19 is connected between one of the rotating rods 17 and the driving end of the first motor 13.

[0035] Specifically, when the first motor 13 is started, the first motor 13 drives one of the rotating rods 17 to rotate through the first transmission belt structure 19, and the rotating rod 17 drives one of the rotating gears 18 to rotate. Since the two rotating gears 18 are meshed and connected, the two rotating gears 18 rotate at the same time, and the rotating gears 18 drive the rotating rod 17 and the crushing roller 2 to rotate, thereby crushing the construction waste.

[0036] See also Figure 1-6, as an implementation method for classifying ferrous metals in crushed construction waste: two conveying rollers 20 are rotatably arranged in the shell 1, a conveyor belt 21 is connected between the two conveying rollers 20, one end of one of the conveying rollers 20 passes through the shell 1 and is connected to a second transmission belt structure 22 between the driving end of the first motor 13, a rotating column 23 rotatably connected to the shell 1 is fixedly arranged on the upper end of the rotating disk 15, a gear ring 24 is fixedly connected to the upper end of the rotating column 23 through the shell 1, and the gear ring 24 is meshedly connected to a driving gear 25, a second motor 26 is fixedly arranged on the upper end of the shell 1, and the driving end of the second motor 26 is fixedly connected to the driving gear 25, and a first collection box 27 and a second collection box 28 are movably connected to both sides of the shell 1.

[0037] Specifically, the construction waste passing through the sieve plate 8 will fall onto the conveyor belt 21, and the guide plate 3 will guide it. When the first motor 13 is started, the first motor 13 drives one of the conveyor rollers 20 to rotate through the second transmission belt structure 22, so that the conveyor belt 21 runs to convey the construction waste. The electromagnet 16 above the conveyor belt 21 is started, and the iron-containing metal waste in the conveyed construction waste will be adsorbed by the electromagnet 16, and the remaining construction waste will fall into the first collection box 27 through the conveyor belt 21, and the second electromagnet 16 is started regularly. The second motor 26 drives the driving gear 25 to rotate, the driving gear 25 drives the gear ring 24 to rotate, the gear ring 24 drives the rotating column 23 to rotate, the rotating column 23 drives the rotating disk 15 to rotate 180 degrees, so that the positions of the two electromagnets 16 are exchanged, the electromagnet 16 above the conveyor belt 21 is started, so that it continues to adsorb the ferrous metal waste in the construction waste, and the electromagnet 16 rotated to the top of the second collecting box 28 is closed, so that the adsorbed ferrous metal waste falls into the second collecting box 28 for collection, thereby classifying it.

[0038] See also Figure 1-6 As an implementation method for cleaning the conveyor belt 21: a support seat 29 is fixedly provided in the shell 1, and two limit rods 30 are movably passed through the support seat 29, and the upper ends of the two limit rods 30 are fixedly connected with a cleaning plate 31, and a second spring 32 is movably sleeved on the outer side of each limit rod 30, and the lower end of each limit rod 30 passes through the support seat 29 and is fixedly connected to a limit plate 33.

[0039] Specifically, the limit plate 33 can limit the moving position of the limit rod 30. Under the push of the second spring 32, the cleaning plate 31 contacts the conveyor belt 21. As the conveyor belt 21 runs, the cleaning plate 31 scrapes and cleans the construction waste adhered to the conveyor belt 21, so that the construction waste falls into the first collection box 27 together.

[0040] To sum up, when the overall equipment is in use:

[0041] When the construction waste needs to be crushed, a feed hopper is provided at the upper end of the shell 1, and the construction waste is placed from the feed hopper into the shell 1, and then moved along the two guide plates 3 between the two crushing rollers 2, and the first motor 13 is started. The first motor 13 drives one of the rotating rods 17 to rotate through the first transmission belt structure 19, and the rotating rod 17 drives one of the rotating gears 18 to rotate. Since the two rotating gears 18 are meshed and connected, the two rotating gears 18 rotate at the same time, and the rotating gear 18 drives the rotating rod 17 and the crushing roller 2 to rotate, so as to crush the construction waste. The crushed construction waste will fall onto the sieve plate 8 and pass through the sieve plate 8, while some soft plastic waste such as water pipes in the construction waste will not be crushed, so that they are intercepted by the sieve plate 8. At the same time, when the first motor 13 is started, the first motor 13 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the half gear 12 to rotate. When the half gear 12 rotates to engage with the rack 9, as the half gear 12 rotates, the rack 9 moves upward, the rack 9 drives the sieve plate 8 to move upward, and the sieve plate 8 drives the lifting rod 5 and the push ring 6 to move upward, and the first spring 7 is compressed. When the half gear 12 rotates to separate from the rack 9, under the action of the first spring 7 and gravity, the sieve plate 8 drives the lifting rod 5 and the push ring 6 to move back to their original positions. Repeating this operation causes the sieve plate 8 to vibrate, which can speed up the screening of the crushed waste to prevent blockage. At the same time, the sieve plate 8 is tilted so that the intercepted plastic waste is discharged from the sewage outlet 14 along the sieve plate 8.

[0042] When it is necessary to classify the ferrous metal waste in the construction waste, the construction waste passing through the screen plate 8 will fall onto the conveyor belt 21, and the guide plate 3 will guide it. When the first motor 13 is started, the first motor 13 drives one of the conveying rollers 20 to rotate through the second transmission belt structure 22, so that the conveyor belt 21 runs to transport the construction waste, and the electromagnet 16 above the conveyor belt 21 is started. The ferrous metal waste in the transported construction waste will be adsorbed by the electromagnet 16, and the remaining construction waste will fall into the first collection box through the conveyor belt 21. 27, the second motor 26 is started at a fixed time, the second motor 26 drives the driving gear 25 to rotate, the driving gear 25 drives the gear ring 24 to rotate, the gear ring 24 drives the rotating column 23 to rotate, the rotating column 23 drives the rotating disk 15 to rotate 180 degrees, so that the positions of the two electromagnets 16 are exchanged, the electromagnet 16 above the conveyor belt 21 is started, so that it continues to adsorb the ferrous metal waste in the construction waste, and the electromagnet 16 rotated to the second collection box 28 is closed, so that the adsorbed ferrous metal waste falls into the second collection box 28 for collection, thereby classifying it.

[0043] When the conveyor belt 21 needs to be cleaned, the limit plate 33 can limit the position of the limit rod 30. Under the push of the second spring 32, the cleaning plate 31 contacts the conveyor belt 21. As the conveyor belt 21 runs, the cleaning plate 31 scrapes and cleans the construction waste adhered to the conveyor belt 21, and makes it fall into the first collection box 27. The entire device is controlled by a controller. Since the equipment matched with the controller is a common equipment and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be repeated here.

[0044] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
