[0019] like Figures 1-10 As shown, a construction waste recycling device includes a frame 1 and a crusher 4 arranged on one side of the top of the frame 1. The crusher 4 can crush materials such as concrete blocks, and a conveyor belt 2 for conveying the crushed concrete is also installed on the frame 1. Figure 1 It can be seen that the conveyor belt 2 is located below the crusher 4 so that the concrete blocks passing through the crusher 4 can fall onto the conveyor belt 2 .

[0020] An adsorption component for adsorbing metal in concrete is provided on the top of the conveyor belt 2. Figure 1-Figure 7 As shown, the adsorption assembly includes a roller 3 as a carrier and a magnetic plate 13 and a pressure plate 14 fixedly sleeved on the outside of the roller 3 (the outer wall of the pressure plate 14 can be roughened). Figure 5 、 Figure 7 As can be seen in the figure, the magnetic plate 13 and the pressure plate 14 are both arc-shaped and completely surround the roller 3. During the rotation of the two rollers 3, the metal in the concrete block can be adsorbed by the magnetic plate 13. Furthermore, in order to collect the metal adsorbed on the surface of the magnetic plate 13, a scraping assembly is provided between the two rollers 3. Specifically, the scraping assembly includes a storage rack 18 provided between the two rollers 3. Both ends of the bottom of the storage rack 18 are hinged with a shovel plate 23. Figure 7 、 Figure 10 As shown, the shovel plate 23 can be attached to the outside of the magnetic plate 13 and the pressure plate 14, and a storage chamber for storing metal is formed between the shovel plate 23 and the storage rack 18. Since the pressure plate 14 is not magnetic, when the roller 3 drives the pressure plate 14 close to the shovel plate 23, the metal adsorbed on the magnetic plate 13 can be shoveled off by the shovel plate 23 and fall into the above-mentioned storage chamber, thereby completing the collection of the metal.

[0021] During actual use, if there are still concrete blocks stuck on the metal, they can also be adsorbed by the magnetic plate 13. In order to solve this problem, this solution has a top plate 16 hinged at the pressure plate 14 for lifting the scraping assembly. In the initial state, the top plate 16 is in a retracted state, so that the outer side surfaces of the top plate 16, the magnetic plate 13 and the pressure plate 14 are flush. When there are concrete blocks stuck on the adsorbed metal surface, the top plate 16 can bounce relative to the pressure plate 14. Thereafter, during the rotation of the roller 3, the bounced top plate 16 can push the storage rack 18 and the shovel plate 23 upward, so that the metal with the concrete blocks stuck can fall between the two rollers 3.

[0022] In order to prevent the metal with concrete blocks attached to it from entering the storage chamber, a pulling unit that cooperates with the shovel plate 23 is provided in the storage rack 18. When the detection unit 8 detects that the metal adsorbed on the magnetic plate 13 is attached to a concrete block, the pulling unit can pull up the shovel plate 23 so that one end of the shovel plate 23 deflects upward and fits into the storage rack 18. Figure 10 As shown, the accommodating chamber can be in a closed state.

[0023] like Figure 7 As shown, in the initial state, the top plates 16 on the two pressure plates 14 are in an asymmetric state, so that the two pressure plates 14 will not approach the conveyor belt 2 at the same time. Through this arrangement, the two magnetic plates 13 can cooperate with each other and continuously adsorb the metal remaining on the conveyor belt 2. According to the above description, when the top plate 16 lifts the scraping component, the metal with concrete blocks adhered to it can fall between the two adsorption components, and then be squeezed and crushed by the adsorption components. In actual use, if the concrete blocks adhered to the metal are crushed by the magnetic plate 13, the magnetic plate 13 may be damaged. Therefore, this scheme squeezes and crushes the concrete blocks adhered to the metal by cooperating with the pressure plates 14 on the two rollers 3.

[0024] In order for the two pressing plates 14 to cooperate with each other, a base 22 is fixedly provided on the inner wall of the roller 3. Figure 8 As shown, an arc-shaped rod 2201 that cooperates with the top plate 16 is fixedly provided on the base 22, and the center of the arc-shaped rod 2201 is in a collinear state with the rotation center of the top plate 16, and the end of the arc-shaped rod 2201 away from the base 22 extends into the top plate 16 and slides with it. An arc-shaped spring is sleeved on the outside of the arc-shaped rod 2201, and the two ends of the arc-shaped spring are respectively fixedly connected to the top plate 16 and the base 22. The top plate 16 passes through the pressure plate 14 and can rotate relative to the pressure plate 14, and the position where the pressure plate 14 and the top plate 16 are hinged is located on the outer peripheral surface of the top plate 16 and close to the bottom end; Further, combined with Figures 8-11As shown, a cylinder is fixedly provided at the side of the base 22 away from the top plate 16, and an electromagnet 26 is fixedly installed at the end surface of the cylinder away from the base 22, and an insertion rod 25 is elastically connected to the cylinder. The insertion rod 25 is made of iron, and the insertion rod 25 passes through the base 22 and slides with it. A slot 1601 that cooperates with the insertion rod 25 is opened on the side of the top plate 16. In the initial state, the end of the insertion rod 25 away from the electromagnet 26 is inserted into the slot 1601 to limit the top plate 16. When the detection unit 8 detects that the metal adsorbed on the magnetic plate 13 is adhered to a concrete block, the electromagnet 26 can be in an energized state, so that the suction force of the electromagnet 26 on the insertion rod 25 can move one end of the insertion rod 25 out of the slot 1601.

[0025] The traction unit includes a winding shaft 20 disposed in the storage rack 18, a traction rope 24 is fixedly disposed between the winding shaft 20 and the shovel plate 23, and the traction rope 24 passes through the storage rack 18 and slides with it. Figure 1-Figure 5 As shown, a U-shaped bracket 6 is fixedly installed on the top of the frame 1, and guide blocks 19 are slidably assembled on both sides of the bracket 6. The winding shaft 20 passes through the guide block 19 and rotates with it through bearings. During actual operation, a motor 7 is installed on one of the guide blocks 19, so that the end of the winding shaft 20 passing through the guide block 19 can be connected to the output shaft of the motor 7. When the detection unit 8 detects that the metal surface of the magnetic plate 13 is adhered to a concrete block, the detection unit 8 can control the motor 7 to drive the winding shaft 20 to rotate, and then wind the traction rope 24, which is conducive to pulling the shovel plate 23 upward, so that the shovel plate 23 can seal the accommodating chamber.

[0026] In order to install the roller 3, this solution is equipped with a base 102 on the frame 1, and connecting pipes 27 are fixedly provided at the end surfaces of both ends of the roller 3. The connecting pipes 27 pass through the base 102 and rotate with it through bearings. A collar 28 is sleeved on the outer side of the connecting pipe 27. A boss 103 is installed on the frame 1, and a driving motor is installed on the boss 103. A pulley is fixedly sleeved on the output shaft of the driving motor, and a belt is sleeved between the pulley and the collar 28 to drive the roller 3 to rotate. Of course, the roller 3 can also be driven to rotate by a transmission method such as a chain. Reference Figure 12-13 As shown, a sleeve 29 is slidably mounted in the connecting tube 27, and the top of the sleeve 29 is elastically connected to the limit rod 21. A strip groove 2701 for sliding the limit rod 21 is provided on the wall of the connecting tube 27, so that the limit rod 21 can slide along the axis direction of the connecting tube 27, and a plurality of notches 2801 are evenly provided on the inner wall of the collar 28 to match the limit rod 21. Figure 13It can be seen that the inner wall of the collar 28 is recessed inward at the rear position of the notch 2801 to form an annular groove 2802. The top of the limiting rod 21 is a spherical structure. In the initial state, the limiting rod 21 is in the annular groove 2802, so that the intersection of the annular groove 2802 and the notch 2801 contacts the spherical surface on the limiting rod 21. When the top plate 16 at one of the rollers 3 is in a pop-up state and rotates to the side of the scraping assembly, the cooperation of a single limiting rod 21 and the collar 28 is not enough to drive the top plate 16 to pass over the scraping assembly. Figure 10 As shown, when the top plate 16 on the other roller 3 rotates to the side of the scraping assembly, the scraping assembly can be pushed upward through the cooperation of the two sets of limit rods 21 and the collar 28, so that the metal with the concrete block adhered to the pressure plate 14 can fall between the two adsorption assemblies.

[0027] Reference Figure 1-Figure 2 、 Figure 12-13 As shown, a cylinder 30 is provided at the end position of the connecting pipe 27, and the telescopic end of the cylinder 30 is fixedly connected to the sleeve 29. The sleeve 29 can be pulled by the cylinder 30 so that the limiting rod 21 is aligned with the slot 2801. At this time, the spherical structure at the top of the limiting rod 21 can be completely in the slot 2801, so that the top of the limiting rod 21 will not move out of the slot 2801, and the ring 28 can also stably drive the connecting pipe 27 and the roller 3 to rotate.

[0028] In actual use, the concrete blocks passing through the crusher 4 can fall onto the conveyor belt 2, and the conveyor belt 2 can transport the crushed concrete. The magnetic plates 13 on the outside of the two rollers 3 can adsorb the metal in the concrete blocks, and the provided shovel plate 23 can gather and collect the metal adsorbed on the magnetic plates 13. In addition, the provided pressing plate 14, as the pressing plate 14 gradually rotates to the shovel plate 23, the gathered metal can be pushed onto the pressing plate 14, and then fall into the accommodating chamber between the shovel plate 23 and the storage rack 18 for storage. When the detection unit 8 detects that the metal surface adsorbed on the magnetic plate 13 is adhered to a concrete block, the detection unit 8 can control the motor 7 to drive the shaft 20 to rotate. During the rotation of the shaft 20, the traction rope 24 can be wound and the shovel plate 23 can be pulled to deflect upward, thereby preventing the metal with the concrete block adhered to it from entering the accommodating chamber. The detection unit 8 can control the electromagnet 26 to be in an energized state, so that one end of the insertion rod 25 moves out of the slot 1601, and the top plate 16 pops out under the pressure of the arc spring. Figure 8 、 Figure 10As shown, according to the above description, when only one of the top plates 16 moves to the side of the storage rack 18, the force between the limit rod 21 and the collar 28 is not enough to lift the storage rack 18 and other structures upward. Therefore, as the pressure between the limit rod 21 and the collar 28 increases, one end of the limit rod 21 can move out from the intersection of the annular groove 2802 and the notch 2801, and as the other top plate 16 also moves to the side of the storage rack 18, the cooperation of the two sets of limit rods 21 and the collar 28 can overcome the gravity of the storage rack 18 and other structures to lift it up, and the metal with the concrete block adhered to the pressure plate 14 will also fall between the two adsorption components. In actual operation, a The first switch 17 for controlling the cylinder 30 can contact the first switch 17 when the storage rack 18 is pushed upward, thereby starting the cylinder 30 through the first switch 17. The cylinder 30 can pull the sleeve 29 outward along the axis of the connecting pipe 27, so that the limit rod 21 can be aligned with the slot 2801, and the cooperation between the limit rod 21 and the slot 2801 enables the ring 28 to stably drive the connecting pipe 27 and the roller 3 to rotate. In this state, the two pressure plates 14 will be aligned with each other and move downward synchronously. The cooperation of the two pressure plates 14 can crush the concrete blocks adhered to the metal surface, and the metal also falls onto the conveyor belt 2 and is finally re-adsorbed by the magnetic plate 13.

[0029] Reference Figure 4-Figure 9 As shown, a slider 10 is elastically connected to the bracket 6, and the slider 10 is an "I"-shaped structure. A slide groove is provided on the bracket 6 to slide with the slider 10. A spring is fixed between the inner end surface of the slide groove and the slider 10, and a rotating block 11 is hinged at one end of the slider 10. The specific hinge position is located at the top surface of the slider 10, so that in the horizontal state, the rotating block 11 can only deflect upward relative to the slider 10, Figure 6It can be seen that an inclined surface 1101 is provided on the side of the top of the rotating block 11 away from the slider 10, and an L-shaped push rod 1801 is fixedly provided on the top surface of the storage rack 18. A second switch 9 is installed on the top of the bracket 6. The second switch 9 is located at one end of the slider 10 away from the rotating block 11. The second switch 9 is connected to one of the driving motors, and a through slot for the push rod 1801 to pass through is provided on the bracket 6. In actual use, when the two top plates 16 cooperate with each other to push the storage rack 18 upward, the push rod 1801 can lift the rotating block 11 and deflect it upward. When the concrete block between the two adsorption components is broken and the storage rack 18 moves downward to reset, the push rod 1801 will cooperate with the inclined surface 1101 and push the slider 10 so that the slider 10 contacts the second switch 9. , and then the second switch 9 is used to control the speed of one of the drive motors to increase within a certain period of time, so that the pressure plates 14 on the two rollers 3 can be in an asymmetric state again for the next use. When in use, a first time relay can be set in the circuit between the first switch 17 and the cylinder 30, and a second time relay can be set between the second switch 9 and one of the drive motors. Specifically, when the storage rack 18 moves upward and contacts the first switch 17, the cylinder 30 can pull the sleeve 29 outward, and when the storage rack 18 falls downward and resets and disengages from the first switch 17, the cylinder 30 can drive the sleeve 29 to reset after the time set by the first time relay. During this time, the pressure plate 14 can pass through the pressure rod 5 set between the two adsorption components. Figure 7 As shown, the pressure rod 5 is provided to drive the top plate 16 to reset, and the insertion rod 25 is provided to cooperate with the slot 1601 to re-lock the top plate 16. As the storage rack 18 falls back and triggers the second switch 9, the speed of one of the drive motors can be increased after the time set by the second time relay, so that one of the top plates 16 can be staggered with the other top plate 16 after being reset by the pressure rod 5, so that the two top plates 16 are in an asymmetric state again. The structures of the first time relay and the second time relay are mature technical means in the electrical field and will not be elaborated here.

[0030] like Figures 1-10 As shown, multiple groups of rollers 3 are provided on the inner side of the conveyor belt 2 for supporting the conveyor belt 2, and lower hangings 101 are provided at both ends of the conveyor belt 2. The lower hangings 101 are fixedly connected to the frame 1, and a rotating shaft is fixedly provided on the end face of the roller 3 close to the lower hanging 101. The rotating shaft passes through the lower hanging 101 and rotates with it. Specifically, a first motor 7 is installed on the frame 1, and the first motor 7 is connected to one end of the rotating shaft passing through the lower hanging 101 for driving the conveyor belt 2 to rotate.

[0031] The crusher 4 is fixed on the frame 1 through columns.

A vertical rod (not shown in the figure) can be fixedly installed on the bottom surface of the guide block 19, and the vertical rod passes downward through the partition and slides with it.

[0033] Side plates 1802 are fixedly provided at both ends of the storage rack 18 , and the shovel plate 23 is in contact with the side plates 1802 , thereby preventing the metal from being moved out of the accommodation chamber.

[0034] Reference Figure 4 As shown, a baffle 104 is fixedly mounted on the frame 1 , and the baffle 104 can be attached to the outer sides of the magnetic plate 13 and the pressure plate 14 , thereby preventing the adsorbed metal from falling from both ends of the magnetic plate 13 .

A pressure strip 15 is provided below the shaft 20, and a fixing rod is welded between the pressure strip 15 and the sleeve 2001, and between the sleeve 2001 and the storage rack 18. Figure 5 It can be seen that the pressure strip 15 is provided with an avoidance groove 1401 that cooperates with the top plate 16. In actual use, when the top plate 16 passes over the storage rack 18 and the storage rack 18 is reset downward, the pressure strip 15 can squeeze the concrete blocks between the two adsorption components, so that the two pressure plates 14 that cooperate with each other can stably crush the concrete blocks.

[0037] from Figure 7 As can be seen in the figure, the pressure rod 5 can be attached to the outer surface of the pressure plate 14 or the magnetic plate 13, and the pressure rod 5 is fixedly installed on the bracket 6.

[0038] During actual use, a compression spring may be installed between the shovel plate 23 and the storage rack 18 so that the shovel plate 23 can be stably attached to the outer side of the magnetic plate 13 or the pressure plate 14 .

[0039] The detection unit 8 can be a visual sensor, such as an industrial CCD camera. The visual sensor is fixed on both sides of the top of the bracket 6. The visual sensor is signal or electrically connected to the above-mentioned electromagnet 26 and the motor 7. When the visual sensor detects that the metal adsorbed on the magnetic plate 13 is adhered to a concrete block, the motor 7 and the electromagnet 26 can be started.

[0040] Reference Figure 11As shown, the cross section of the rod 25 is a T-shaped structure, and a tension spring is provided between the end face of the rod 25 and the base 22 . When the electromagnet 26 is in a de-energized state, the rod 25 can move toward the direction close to the top plate 16 .

[0041] Reference Figure 12 As shown, a first spring is fixedly arranged between the inner end surface of the sleeve 29 and the limit rod 21, a guide groove (not shown in the figure) is opened on the inner wall of the connecting tube 27, and a guide rod (not shown in the figure) is fixedly arranged on the sleeve 29 and slides with the guide groove, so that the sleeve 29 can slide stably relative to the connecting tube 27.

Figure 13 It can be seen from the figure that position b is far away from the limiting rod 21 . Therefore, when the cylinder 30 pulls the sleeve 29 to move outward, the spherical surface on the limiting rod 21 can be completely located in the notch 2801 .

[0043] Reference Figure 1-Figure 2 As shown, the base 102 and the boss 103 can be connected as a whole. This whole structure can be fixedly mounted on the frame 1 or slidably assembled on the frame 1. When the base 102 and the boss 103 are slidably assembled on the frame 1, they are elastically matched with the frame 1, so that the distance between the two adsorption components can be adjusted, and the above-mentioned cylinder 30 is fixedly connected to the base 102.
