Description

Technical Field

[0001] This application relates to the field of material adsorption, specifically to a waste iron adsorption device for construction waste treatment. Background Technology

[0002] In modern construction engineering, green raw materials are frequently used in new building construction. A significant portion of this involves reprocessing steel bars from demolished and broken buildings to meet construction standards. Using such green building materials effectively reduces material costs during construction. Furthermore, demolishing and breaking up abandoned buildings prevents their prolonged existence, eliminates safety risks, and significantly improves the surrounding environment and urban landscape. Currently, electromagnetic chucks are commonly used to collect and transport steel bars and other steel materials from abandoned buildings. However, after a building is broken up, a large amount of concrete debris is formed, and the steel bars are often mixed in with this debris. This makes it difficult for electromagnetic chucks to effectively pick up the steel bars compressed by the concrete debris. Using electromagnetic chucks to move the concrete also shortens their lifespan. Therefore, the current method of using excavators in conjunction with electromagnetic chucks for steel bar collection is inefficient and significantly increases collection costs.

[0003] For example, a scrap steel handling electric suction cup disclosed in CN215854558U has a structure including a suction cup body and a vibration assembly of a vibrating suction cup. The vibration assembly includes a support frame and at least one vibrating component. The support frame is located at the upper end of the suction cup body, and the vibrating component is located at the end of the support frame away from the suction cup body. A vibrating element is connected to the end of the vibrating component near the suction cup body. The vibrating component is used to drive the vibrating element to strike the suction cup body. The above-mentioned electric suction cup reduces the possibility of scrap iron falling off during handling by using the vibrating component to drive the vibrating element to strike the suction cup body. However, it cannot solve the problem that the reinforcing steel bars inside concrete fragments are not easy to be attracted. Moreover, the vibration strikes off the reinforcing steel bars that may fall off, reducing the number of reinforcing steel bars transferred at one time and reducing the work efficiency. Therefore, this application designs a scrap iron adsorption device for construction waste handling that can easily attract the reinforcing steel bars inside concrete fragments and prevent the reinforcing steel bars from falling off during the transfer process. Utility Model Content

[0004] The purpose of this invention is to provide a waste iron adsorption device for construction waste treatment, which aims to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste iron adsorption device for construction waste treatment, comprising an electromagnetic chuck, a double-layer hopper, and a vibration mechanism that vibrates out the reinforcing steel bars from concrete fragments; the electromagnetic chuck is connected to the excavator boom, the double-layer hopper is rotatably connected to the electromagnetic chuck, and the vibration mechanism is located inside the double-layer hopper. The double-layer hopper scoops up the concrete fragments, and the vibration of the vibration mechanism causes the reinforcing steel bars inside the concrete fragments to be vibrated out, thereby allowing the electromagnetic chuck to adsorb and collect the reinforcing steel bars. At the same time, the double-layer hopper supports the falling reinforcing steel bars during the transfer of the reinforcing steel bars.

[0006] The double-layer hopper scoops up the concrete fragments and steel reinforcement mixture, and the vibration mechanism causes the concrete fragments and steel reinforcement to continuously change positions within the double-layer hopper. This allows the electromagnetic chuck to attract the steel reinforcement buried inside the concrete fragments, eliminating the need for an excavator and effectively reducing steel reinforcement collection costs while improving operational efficiency.

[0007] Furthermore, the electromagnetic chuck is equipped with a mounting bracket at its upper end, and the electromagnetic chuck is movably connected to the excavator boom through the mounting bracket. An electric rotating shaft is provided on the side of the electromagnetic chuck, and the electromagnetic chuck is rotatably connected to the double-layer hopper through the electric rotating shaft.

[0008] Furthermore, the double-layer hopper includes an outer back plate, an inner back plate, an outer bottom plate, an inner bottom plate, side plates, and assisting components. The outer back plate is inserted into the electric rotating shaft, and its lower end is welded to the outer bottom plate. The side plates are welded to both sides of the outer bottom plate. The inner bottom plate and outer bottom plate are movably connected via a vibration mechanism. The inner back plate and outer back plate are movably connected via the assisting components, and the inner back plate is welded to the inner bottom plate. The assisting components include an array of assisting springs and an array of ball bearings. One end of each assisting spring is fixedly connected to the inner back plate, and the other end is fixedly connected to the outer back plate. The ball bearings are located on both sides of the inner bottom plate and can roll inside the inner bottom plate, with their outer surfaces contacting the side plates. By positioning the double-layer hopper below the electromagnetic chuck during the transfer process after the rebar has been adsorbed, the hopper catches any falling rebar, effectively improving the safety of the rebar transfer process without reducing the amount of rebar transferred in a single operation.

[0009] Furthermore, an inclined plate extending diagonally is provided at the end of the inner bottom plate away from the inner back plate. The inclined plate makes it easier for the double-layer hopper to scoop up concrete fragments, while preventing fragments from being clamped between the inner and outer bottom plates, thus facilitating operation for workers and reducing the possibility of damage to the equipment.

[0010] Furthermore, the vibration mechanism is a vibration motor, the lower end of which is bolted to the outer base plate, and the output end of which is plugged into the inner base plate.

[0011] Furthermore, the vibration mechanism includes a connecting rod, a drive block, a connecting handle, a driven frame, a transverse driven rod, a fixed plate, vibration springs, transverse springs, and eccentric wheels arranged opposite each other. The connecting rod passes through the drive block, and two sets of eccentric wheels are set at both ends of the connecting rod. A double-headed motor is bolted inside the drive block, and the output end of the double-headed motor is inserted into the connecting rod. The connecting rod is rotatably connected to the inside of the drive block. Four sets of vibration springs are arranged opposite each other on the upper and lower parts of the drive block. The other end of the vibration spring is fixedly connected to the driven frame. Four sets of transverse driven rods are arranged on both sides of the driven frame. Fixed plates are fixedly connected to the outer base plate on both sides of the driven frame. The transverse driven rods pass through the fixed plates and are slidably connected to the fixed plates. The transverse springs are sleeved on the transverse driven rods. The transverse springs are fixedly connected to the end of the fixed plate near the driven frame, and the other end of the transverse springs is connected to the outer wall of the driven frame. One end of the connecting handle is connected to the drive block, and the other end of the connecting handle is connected to the inner base plate.

[0012] The eccentric wheel drives the drive block to vibrate, and the transverse spring and transverse driven rod make the vibration of the drive block present a certain circular motion. The vibration of the inner bottom plate causes the material above to be thrown away from the inner back plate. During the vibration, the inner bottom plate gradually throws concrete fragments out of the double-layer hopper, making it easier for the electromagnetic chuck to attract steel bars and further improving the collection efficiency of steel bars.

[0013] Compared with existing technologies, it has the following beneficial effects:

[0014] This utility model provides a waste iron adsorption device for construction waste treatment. The device uses a double-layer hopper to scoop up the mixture of concrete fragments and steel bars. The vibration of the vibrating mechanism causes the concrete fragments and steel bars to continuously change positions within the double-layer hopper, allowing the electromagnetic chuck to adsorb the steel bars buried under the concrete fragments. This eliminates the need for an excavator, effectively reducing the cost of steel bar collection and improving work efficiency.

[0015] The double-layer hopper is positioned below the electromagnetic chuck during the transfer process after the chuck has finished adsorbing the steel bars, thus catching any falling steel bars. This effectively improves the safety of the steel bar transfer process without reducing the amount of steel bars transferred in one go.

[0016] The eccentric wheel drives the drive block to vibrate, and the transverse spring and transverse driven rod make the vibration of the drive block present a certain circular motion. The vibration of the inner bottom plate causes the material above to be thrown away from the inner back plate. During the vibration, the inner bottom plate gradually throws concrete fragments out of the double-layer hopper, making it easier for the electromagnetic chuck to attract steel bars and further improving the collection efficiency of steel bars.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1 to 5As shown, this utility model provides the following technical solution: a waste iron adsorption device for construction waste treatment, including an electromagnetic chuck 1, a double-layer hopper 2, and a vibration mechanism 3 that vibrates out the reinforcing bars in concrete fragments; the electromagnetic chuck 1 is connected to the excavator boom, the double-layer hopper 2 is rotatably connected to the electromagnetic chuck 1, and the vibration mechanism 3 is set inside the double-layer hopper 2. The double-layer hopper 2 scoops up the concrete fragments, and the vibration of the vibration mechanism 3 causes the reinforcing bars in the concrete fragments to be vibrated out, thereby allowing the electromagnetic chuck 1 to adsorb and collect the reinforcing bars. At the same time, the double-layer hopper 2 supports the fallen reinforcing bars during the transfer of the reinforcing bars.

[0027] See Figure 1 The electromagnetic chuck 1 is provided with a mounting bracket 11 at its upper end, and the electromagnetic chuck 1 is movably connected to the excavator boom through the mounting bracket 11.

[0028] See Figure 1 An electric rotating shaft 12 is provided on the side of the electromagnetic chuck 1, and the electromagnetic chuck 1 is rotatably connected to the double-layer hopper 2 through the electric rotating shaft 12. The electric rotating shaft 12 can also be driven by a cylinder to give the double-layer hopper 2 a greater pushing force, making it easier to collect concrete fragments.

[0029] See Figures 1 to 3 The double-layer hopper 2 includes an outer back plate 21, an inner back plate 22, an outer bottom plate 23, an inner bottom plate 24, a side plate 25, and an assisting component 26. The outer back plate 21 is inserted into the electric rotating shaft 12. The lower end of the outer back plate 21 is welded to the outer bottom plate 23. The side plate 25 is welded to both sides of the outer bottom plate 23. The inner bottom plate 24 is movably connected to the outer bottom plate 23 through the vibration mechanism 3. The inner back plate 22 is movably connected to the outer back plate 21 through the assisting component 26. The inner back plate 22 is welded to the inner bottom plate 24. The connection between the outer bottom plate 23 and the outer back plate 21, as well as the connection between the inner bottom plate 24 and the inner back plate 22, are all L-shaped structures. Two side plates 25 are provided on both sides of the outer bottom plate 23, which play a role in restricting the concrete fragments inside. During operation, the rotation of the electric rotating shaft 12 drives the double-layer hopper 2 to rotate, and then the inner bottom plate 24 scoops up the concrete fragments and steel reinforcement mixture into the double-layer hopper 2. Then, the vibration mechanism 3 is started to vibrate the material in the double-layer hopper 2.

[0030] See Figure 2 and Figure 3The assisting component 26 includes an array of assisting springs 261 and an array of balls 262. One end of the assisting spring 261 is fixedly connected to the inner back plate 22, and the other end is fixedly connected to the outer back plate 21. The balls 262 are disposed on both sides of the inner bottom plate 24 and can roll inside the inner bottom plate 24. The outer side of the balls 262 contacts the side plate 25. When the vibration mechanism 3 vibrates the material in the double-layer hopper 2, the inner bottom plate 24 is driven to vibrate. The balls 262 on the side plate 25 reduce friction, and the assisting springs 261 at the rear end dissipate the force generated by the vibration, preventing the inner back plate 22 from colliding with the outer back plate 21. At the same time, the elastic potential energy generated by the assisting springs 261 further enhances the vibration effect of the inner bottom plate 24.

[0031] See Figure 1 An inclined plate 241 extending diagonally is provided at the end of the inner bottom plate 24 away from the inner back plate 22. When the electric rotating shaft 12 rotates to drive the double-layer hopper 2 to collect materials, the inclined plate 241 contacts the ground, which can more smoothly scoop the materials into the double-layer hopper 2. At the same time, the inclined plate 241 blocks the gap between the inner bottom plate 24 and the outer bottom plate 23, preventing materials from entering the vibration mechanism 3 and causing damage to the device.

[0032] As another embodiment, such as Figure 4 As shown, the vibration mechanism 3 is a vibration motor 301. The lower end of the vibration motor 301 is bolted to the outer base plate 23, and the output end of the vibration motor 301 is inserted into the inner base plate 24. After the material is scooped up by the double-layer hopper 2, the vibration motor 301 is started, causing the vibration motor 301 to drive the inner base plate 24 to vibrate irregularly, so that the concrete fragments and steel bars constantly change positions. The exposed steel bars are attracted by the electromagnetic chuck 1. After vibrating for a period of time, the vibration can be stopped, and the electric rotating shaft 12 is controlled to rotate to dump the remaining concrete fragments, and then the next round of vibrating screening or steel bar transfer is carried out.

[0033] Working principle: When it is necessary to adsorb steel bars in the concrete crusher and steel bar mixture, the double-layer hopper 2 is installed on the electromagnetic chuck 1 via the electric shaft 12. Then, the electromagnetic chuck 1 is connected to the excavator boom. The rotation of the electric shaft 12 drives the double-layer hopper 2 to rotate, and then the material is scooped up into the double-layer hopper 2 by the inclined plate 241. At this time, the double-layer hopper 2 is at the lower end of the electromagnetic chuck 1. The vibration motor 301 is started, so that the output end of the vibration motor 301 drives the inner bottom plate 24 to vibrate, so that the concrete crushers and steel bars in the double-layer hopper 2 continuously change positions. The electromagnetic chuck 1 adsorbs the exposed steel bars. After the adsorption is completed, the electric shaft 12 is rotated in the opposite direction to unload the concrete crushers for the next cycle or for steel bar transfer. During the steel bar transfer, the double-layer hopper 2 is rotated to the lower part of the electromagnetic chuck 1 so that the double-layer hopper 2 can carry the steel bars that fall from the electromagnetic chuck 1.

[0034] As another embodiment, such as Figures 5 to 7 As shown, the vibration mechanism 3 includes a connecting rod 311, a drive block 312, a connecting handle 313, a driven frame 314, a transverse driven rod 315, a fixed plate 316, vibration springs 317, transverse springs 318, and eccentric wheels 319 arranged opposite each other. The connecting rod 311 passes through the drive block 312, and two sets of eccentric wheels 319 are arranged at both ends of the connecting rod 311. A double-headed motor is bolted inside the drive block 312, and the output end of the double-headed motor is inserted into the connecting rod 311. The connecting rod 311 is rotatably connected to the inside of the drive block 312. Four sets of vibration springs 317 are arranged opposite each other on the upper and lower sides of the drive block 312. The other end of the vibration spring 317 The driven frame 314 is fixedly connected to the driven frame 314. Four sets of transverse driven rods 315 are provided on both sides of the driven frame 314. Fixed plates 316 are provided on both sides of the driven frame 314 and are fixedly connected to the outer base plate 23. The transverse driven rods 315 pass through the fixed plates 316 and are slidably connected to the fixed plates 316. A transverse spring 318 is sleeved on the transverse driven rods 315. The transverse spring 318 is fixedly connected to one end of the fixed plate 316 near the driven frame 314. The other end of the transverse spring 318 is connected to the outer wall of the driven frame 314. One end of the connecting handle 313 is connected to the drive block 312, and the other end of the connecting handle 313 is connected to the inner base plate 24.

[0035] After the material is scooped up by the double-layer hopper 2, the double-head motor is started, which drives the eccentric wheels 319 on both sides of the drive block 312 to rotate. The vibration spring 317 causes the rotating rod to drive the drive block 312 to vibrate irregularly, which in turn causes the driven frame 314 to move. The transverse spring 318 and the transverse driven rod 315 make the driven frame 314 move only in a horizontal direction, which in turn causes the drive block 312 to move horizontally. Combined with the vertical vibration of the drive block 312 itself, the vibration is transmitted to the inner bottom plate 24 through the connecting handle 313, so that the inner bottom plate 24 exhibits a certain degree of circular motion when vibrating. This throws the material in the double-layer hopper 2 toward the inclined plate 241, so that the concrete fragments are gradually discharged from the double-layer hopper 2 while vibrating and screening. As the concrete fragments decrease, the electromagnetic chuck 1 will be able to attract the steel bars more quickly, and at the same time reduce the situation where there are steel bars that cannot be attracted during vibrating and screening.

[0036] Working principle: When it is necessary to adsorb steel bars in the concrete crusher's steel bar mixture, the double-layer hopper 2 is installed onto the electromagnetic chuck 1 via the electric rotating shaft 12. Then, the electromagnetic chuck 1 is connected to the excavator boom. The rotation of the electric rotating shaft 12 drives the double-layer hopper 2 to rotate, thereby scooping up the material into the double-layer hopper 2 via the inclined plate 241. At this time, the double-layer hopper 2 is at the lower end of the electromagnetic chuck 1. The dual-head motor is started, causing the motor to drive the eccentric wheel 319 to rotate. The vibration of the set drive block 312 causes the driven frame 314 to move. The transverse spring 318 and the transverse driven rod 315 restrict the movement of the driven frame 314. 14 drives the drive block 312 to generate a horizontal reciprocating motion. The drive block 312 transmits the vibration to the inner bottom plate 24 through the connecting handle 313, so that the inner bottom plate 24 exhibits a certain degree of circular motion when vibrating, which throws the material in the double-layer hopper 2 toward the inclined plate 241, so that the concrete fragments are gradually discharged from the double-layer hopper 2 while vibrating and screening. After the concrete fragments are completely discharged from the double-layer hopper 2, the next cycle operation or the transfer of steel bars can be carried out. During the transfer of steel bars, the double-layer hopper 2 is rotated to the lower part of the electromagnetic chuck 1 so that the double-layer hopper 2 can carry the steel bars that fall from the electromagnetic chuck 1.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
