A plurality of groups of servo motors are embedded and installed on the inner embedded plate 226, and the output ends of the plurality of groups of servo motors are all transmission-connected to one end of the second magnetic roller 227. , an axle pin 228 is embedded and installed on the outer wall of the inner embedded plate 226 and on the side away from the central axis 225, the inner wall of the guide frame 221 is fixedly connected to the filter housing 2210, and a plurality of adsorption holes 2211 are opened on the inner wall of the filter housing 2210, and an adsorption pipe 2212 is connected to the outer wall of the filter housing 2210 and on the side away from the plurality of adsorption holes 2211, the other end of the adsorption pipe 2212 passes through the recovery box 3 and is connected to the vacuum suction pump, a dual-axis motor 2213 is fixedly connected to the center of the central axis of the inner wall of the arc plate 222, and the output end of the dual-axis motor 2213 is transmission-connected to the fourth electric push rod 229, and the output end of the fourth electric push rod 229 is transmission-connected to the axle pin positioning sleeve 2214, and the axle pin positioning sleeve 2214 is rotatably connected to the axle pin 228.

[0045] Specifically, the continuous operation of the conveyor belt 2 conveys the construction waste toward the first magnetic roller 41, and the output end of the first electric push rod drives the first magnetic roller 41 to move horizontally, and adjusts the distance between the first magnetic roller 41 and the two sets of crushing rollers 5, so that the construction waste falling between the two sets of crushing rollers 5 can be adsorbed by the metallic iron materials in the construction waste before being crushed;

[0046] The bolt 47 is separated from the positioning sleeve 46, so that the tool holder 42 and the positioning sleeve 46 are in a rotatable and adjustable state. When the scraper plate 43 and the discharge frame 18 are at the same level, the metallic iron material adsorbed by the first magnetic roller 41 can be dropped into the discharge frame 18 under the action of the scraper plate 43 and stored on the top of the discharge table 17 for recycling the ferrous metal material in the process of sorting construction waste.

[0047] The output end of the cylinder 10 drives the crushing roller 5 to fall, and the construction waste after the iron and metal materials are adsorbed by the first magnetic roller 41 falls to a position at the same level as the hazardous waste recycling box 12. The output end of the third electric push rod 62 is then used to drive the two sets of belt rails 611 to rise through the linkage rod 63, so that the two sets of belt rails 611 are separated from the two ends of the crushing roller 5. The output end of the first motor 7 is then used to drive the screw rod 68 to rotate to one side, so that the second guide sleeve 67 is threadedly connected to the screw rod 68, and the two sets of belt rails 611 are driven to approach each other, clamping the construction waste harmful substances such as paint, coating or adhesive on the top of the two sets of crushing rollers 5, and then using the conveying function of the two sets of belt rails 611 to transport the clamped harmful substances into the hazardous waste recycling box 12;

[0048] The top opening of the hazardous waste recycling box 12 is used to temporarily store fallen hazardous materials. When the hazardous materials fall, they first come into contact with the movable plate 23. The spring on the guide rod 24 at the bottom of the movable plate 23 is used to buffer the fallen hazardous materials, preventing paint, coatings or adhesives in the hazardous materials from breaking due to gravity and affecting the pollution in the hazardous waste recycling box 12. It is used for the recovery of hazardous materials in the process of sorting construction waste.

[0049] The output end of the second motor 9 drives the crushing rollers 5 to rotate, crushing the concrete blocks between the two groups of crushing rollers 5. The fallen powdered building materials first enter the filter housing 2210. The continuous operation of the vacuum suction pump generates negative pressure near the groups of adsorption holes 2211, thereby reducing dust on the crushed building materials, thereby improving the environmental friendliness of the overall structure of the recycling device.

[0050] The output end of the dual-axis motor 2213 rotates counterclockwise, and the output end of the fourth electric push rod 229 pushes the shaft pin 228, so that one end of the inner panel 226 rotates around the central axis 225, so as to form a guide structure for the crushed building materials to be discharged by the inner panel 226. The crushed building materials that fall are stored at the bottom of the inner wall of the recycling box 3. The output end of the second electric push rod 20 pushes the push plate 21 to move horizontally, so as to push the crushed building materials at the bottom of the inner wall of the recycling box 3 toward the discharge port 13, so as to complete the sorting of the building waste and facilitate its subsequent recycling.

[0051] The outer wall of the inner panel 226 is connected to a plurality of second magnetic rollers 227 for constantly absorbing the iron metal in the building materials after being crushed and dropped on the inner panel 226. The output end of the dual-axis motor 2213 rotates clockwise, and the output end of the fourth electric push rod 229 pulls the shaft pin 228, so that one end of the inner panel 226 rotates around the central axis 225, so that the inner panel 226 is movably connected to the inner wall of the inner groove 224. Then, the output end of the servo motor is driven by the servo motor to move the inner panel 226 to the inner wall of the inner groove 224. The second magnetic roller 227 rotates in the direction of the central axis 225, and is used to separate the iron metal adsorbed on the surface of the second magnetic roller 227 from the gap connected to the embedded plate 226 during the rotation of the second magnetic roller 227. The diverted iron metal material falls onto the inclined plate 223, and the iron metal that falls on the inclined plate 223 is caused to slide into the discharge table 17 by utilizing the inclination of one end of the inclined plate 223 toward the discharge table 17, so as to be used for the secondary sorting and recovery of the iron metal material after the crushing of the building materials.

[0052] The working principle of the device for sorting and recycling construction waste proposed in the embodiment of the present invention is as follows:

[0053] The conveyor belt 2 continuously operates to convey the construction waste toward the first magnetic roller 41, and the output end of the first electric push rod drives the first magnetic roller 41 to move horizontally, thereby adjusting the distance between the first magnetic roller 41 and the two sets of crushing rollers 5, so that the construction waste that falls between the two sets of crushing rollers 5 can be adsorbed by the metallic iron materials in the construction waste before being crushed;

[0054] The bolt 47 is used to separate the tool holder 42 from the positioning sleeve 46, so that the tool holder 42 and the positioning sleeve 46 are in a rotatable and adjustable state. When the scraper plate 43 and the discharge frame 18 are at the same level, the metallic iron material adsorbed by the first magnetic roller 41 can be dropped into the discharge frame 18 under the action of the scraper plate 43 and stored on the top of the discharge table 17 for recycling the ferrous metal material in the process of sorting construction waste.

[0055] The output end of the cylinder 10 drives the crushing roller 5 to fall, and the construction waste after the iron and metal materials are adsorbed by the first magnetic roller 41 falls to a position at the same level as the hazardous waste recycling box 12. The output end of the third electric push rod 62 is then used to drive the two sets of belt rails 611 to rise through the linkage rod 63, so that the two sets of belt rails 611 are separated from the two ends of the crushing roller 5. The output end of the first motor 7 is then used to drive the screw rod 68 to rotate to one side, so that the second guide sleeve 67 is threadedly connected to the screw rod 68, and the two sets of belt rails 611 are driven to approach each other, clamping the construction waste harmful substances such as paint, coating or adhesive on the top of the two sets of crushing rollers 5. The clamped harmful substances are then transported into the hazardous waste recycling box 12 by the conveying function of the two sets of belt rails 611.

[0056] The top opening of the hazardous waste recycling box 12 is used to temporarily store the fallen hazardous substances. When the hazardous substances fall, they first contact the movable plate 23. The spring on the guide rod 24 at the bottom of the movable plate 23 is used to buffer the fallen hazardous substances, preventing the paint, coating or adhesive in the hazardous substances from breaking due to gravity and affecting the pollution in the hazardous waste recycling box 12. It is used for the recovery of hazardous substances in the process of sorting construction waste.

[0057] The output end of the second motor 9 drives the crushing rollers 5 to rotate, crushing the concrete blocks between the two groups of crushing rollers 5. The fallen powdered building materials first enter the filter housing 2210. The continuous operation of the vacuum suction pump generates negative pressure near the groups of adsorption holes 2211, which reduces dust on the crushed building materials, thereby improving the environmental friendliness of the overall structure of the recycling device.

[0058] The output end of the dual-axis motor 2213 rotates counterclockwise, and the output end of the fourth electric push rod 229 pushes the shaft pin 228, so that one end of the inner panel 226 rotates around the central axis 225, so that the inner panel 226 forms a guide structure for facilitating the discharge of crushed building materials. The crushed building materials that fall are concentrated and stored at the bottom of the inner wall of the recycling box 3. The output end of the second electric push rod 20 pushes the push plate 21 to move horizontally, so as to push the crushed building materials at the bottom of the inner wall of the recycling box 3 toward the discharge port 13, completing the sorting of the building waste, so that it is convenient for later recycling.

[0059] The plurality of second magnetic rollers 227 connected to the outer wall of the inner panel 226 are used to constantly absorb the iron metal in the building materials that have been crushed and dropped on the inner panel 226. The output end of the dual-axis motor 2213 rotates clockwise, and the output end of the fourth electric push rod 229 pulls the shaft pin 228, so that one end of the inner panel 226 rotates around the central axis 225, so that the inner panel 226 is movably connected to the inner wall of the inner groove 224. Then, the plurality of servo motors embedded in the inner panel 226 are used to drive the output end of the servo motor to drive the inner panel 226 to move. The second magnetic roller 227 rotates in the direction of the central axis 225, and is used to separate the iron metal adsorbed on the surface of the second magnetic roller 227 from the gap connected to the embedded plate 226 during the rotation of the second magnetic roller 227. The diverted iron metal material falls onto the inclined plate 223, and the iron metal that falls on the inclined plate 223 is caused to slide into the discharge table 17 by utilizing the inclination of one end of the inclined plate 223 toward the discharge table 17, so as to be used for the secondary sorting and recovery of the iron metal material after the crushing of the building materials.
