Description

Technical Field

[0001] The invention relates to the technical field of construction waste recycling, in particular to a construction waste crushing device for construction engineering. Background Art

[0002] When a building structure needs to be rebuilt or demolished, the floor slab is one of the main parts that needs to be demolished. In the process of demolishing the floor slab, a large amount of construction waste will be generated, including concrete fragments, steel bars, wood, tiles, gypsum boards and other materials. By crushing and sorting the construction waste generated by demolishing the floor slab, the resource utilization of waste can be achieved and pollution to the environment can be reduced.

[0003] At present, for floor slabs with steel bars, when a double-roll crushing device is used for crushing, the crushed floor slabs go in and out of the crushing device, and in order to improve the crushing efficiency, the distance between the double rollers is usually large. Although most of the floor slabs on the surface of the steel bars can be quickly crushed, there will still be some floor slabs smaller than the distance between the double rollers attached to the surface of the steel bars, resulting in incomplete separation, loss of some floor slabs, and reduced recycling of floor slabs; secondly, the steel bars will remain vertically inserted into the ground. Since the steel bars of the floor slabs are generally long, it is not convenient to remove the steel bars from the bottom of the crushing device. Worse still, blockage may occur, affecting the crushing effect of the floor slab.

[0004] Therefore, a construction waste crushing device for construction engineering is proposed to solve the above problems. Summary of the invention

The interior of the floor slabs loses stability due to the stress change, causing the remaining floor slabs to automatically separate and fall off, thereby improving the separation effect of the floor slabs and the steel bars, as well as the recycling amount of the floor slabs. At the same time, the rolled steel bars take up less space and are easy to take out, thereby solving the problems raised in the above-mentioned background technology.

[0019] (III) Beneficial effects

[0020] Compared with the prior art, the present invention provides a construction waste crushing device for construction engineering, which has the following beneficial effects:

[0021] 1. The present invention starts the second motor through the control terminal, and the second motor synchronously drives the two expansion and contraction mechanisms to rotate, driving the upper and lower parts of the steel bars in the gap of the coil plate 1 to pass through the coiling roller, which is squeezed and bent by the coiling roller, and as the length of the steel bar increases after entering the frame, the coil plate 1 bends the steel bar along its own surface, further crushes the floor slabs remaining on the surface of the steel bar, and fully separates the steel bar from the floor slab. After the steel bar is rolled up, the first motor drives the coil plate 1 and the coil plate 2 to separate, and the stripping plate penetrates the isolation cover and the stripping groove on the coiling and bending disk to automatically push the steel bar roll down. Utilizing the above structure, the steel bar is squeezed against the floor slabs remaining on its surface by the change of the curvature of the steel bar and the action of external forces such as the thorns, and the interior of the floor slab loses stability due to the change of stress, resulting in the automatic separation and falling of the remaining floor slabs, thereby improving the separation effect of the floor slabs and the steel bar, as well as the recycling of the floor slabs. At the same time, the rolled steel bar occupies less space and is convenient to be taken out from the bottom of the frame.

[0022] 2. The present invention pushes the inner disk outward of the bending disk through the rebound of the spring telescopic member, and simultaneously shrinks the connecting member 2 and the corresponding coils 1 and 2 inward. At the same time, the compression spring shrinks to retract the thorns on the surface of the thorn plate into the coil 1. By utilizing the above structure, the distance between the coils 1 after winding the steel bars is reduced, so that the coils 1 and the steel bars are relaxed, and the surface of the coils 1 is made smooth, which further facilitates the removal of the steel bars from the coils 1, thereby improving the overall practicality of the device.

[0023] 3. The present invention rotates the gear ring, meshing the transmission gear one and the gear two, and the rotating shaft rotates synchronously with the gear one, so that the "X"-shaped structure drives the straight groove frame to slide back and forth, and then the tooth plate reciprocatingly meshes with the transmission gear sleeve, driving the gear sleeve and the knocking roller on the horn frame one to knock the surface of the steel bar reciprocatingly. At the same time, the wave groove on the vibration plate drives the horn frame two and the arc brush to slide back and forth through the vibration rod, and further processes the residual floor slab by knocking and brushing the surface of the steel bar. During the rotation of the gear two, the cylindrical head slides along the inner surface of the slide groove two, and the transmission swing frame swings back and forth, so that the electromagnet absorbs and separates the rusted metal scraps in the fallen residue. By utilizing the above structure, the rusted metal scraps in the fallen floor slag are separated by knocking and brushing the surface of the steel bar, and the electromagnet swings back and forth, which further improves the effect of separating the steel bar from the floor slab and the subsequent recycling quality of the floor slab.

[0063] For further examples, please refer to Fig.12 As shown:

[0064] It also includes a rust slag collection component 7, which includes a gear 2 71 meshingly installed below the gear ring 9, one side of the gear 2 71 is rotatably connected to the isolation plate 510, and a cylindrical head 72 is fixedly installed at the eccentric center of the other side of the gear 2 71, and the inner side of the isolation cover 51 is rotatably connected to a swing frame 73, and a slide groove 2 74 is provided above the rotating part of the swing frame 73, and an electromagnet 75 for magnetically separating rust slag is fixedly installed below the rotating part of the swing frame 73.

[0065] Preferably, the gear one 63, the gear ring 9 and the gear two 71 are all arranged between the isolation plate 510 and the isolation cover 51, and the isolation plate 510 protects the gear one 63, the gear ring 9 and the gear two 71.

[0066] Preferably, when the knocking roller 610 knocks the surface of the steel bar, the electromagnet 75 can swing downward toward the knocking roller 610.

[0067] Everything in the above example works like this:

[0068] When in use, the steel bar is vertically put into the crushing assembly 2 for crushing, and the crushed steel bar extends vertically to the lower part of the frame 1. When the metal detector 3 detects the steel bar, the signal is transmitted to the control terminal, and the control terminal controls the first motor 41 to drive the double-threaded screw 42 to rotate, and the two isolation covers 51 move toward each other and close together, and the roll plate 1 54 and the roll plate 2 55 are plugged together. In this process, the roll plate 2 55 squeezes the thorns on the surface of the thorn plate 57 along the arc bottom support 58. At this time, the steel bar is located between the two roll plates 1 54. Then, the control terminal starts the second motor 52. The second motor 52 synchronously drives the two expansion and contraction mechanisms 53 to rotate, driving the upper and lower parts of the steel bars in the gap of the coil plate 1 54 to pass through the coiling roller 512, and the steel bars are squeezed and bent by the coiling roller 512. As the length of the steel bars increases as they enter the frame 1, the coil plate 1 54 bends the steel bars along its own surface, further crushing the floor slabs remaining on the surface of the steel bars, so that the steel bars are fully separated from the floor slabs. After the steel bars are rolled up, the first motor 41 drives the coil plate 1 54 and the coil plate 2 55 to separate, and the stripping plate 8 penetrates the stripping groove 513 on the isolation cover 51 and the coiling plate 531 to automatically push the steel bar roll down;

[0069] Furthermore, during the plugging process of the coil plate 1 54 and the coil plate 2 55, the inner disk 532 is compressed toward the coiling disk 531. After the expansion plate 534 is squeezed, the connecting pieces 2 536 on both sides and the corresponding coil plates 1 54 and 2 55 are synchronously expanded outward through the connecting piece 1 535 so that they are located on the same circle. At this time, the spring expansion piece 533 is compressed. During the separation process of the coil plate 1 54 and the coil plate 2 55, the spring expansion piece 533 rebounds, pushing the inner disk 532 outward from the coiling disk 531, and synchronously shrinking the connecting piece 2 536 and the corresponding coil plate 1 54 and 2 55 inward. At the same time, the compression spring 59 shrinks, and the thorns on the surface of the thorn plate 57 are retracted into the coil plate 1 54. By reducing the distance between the coil plates 1 54 after the steel bars are rolled up, the coil plate 1 54 and the steel bars are relaxed, and the surface of the coil plate 1 54 is made smooth, so that the steel bars can be removed easily.

[0070] Furthermore, during the rotation of the bending disk 531, the gear ring 9 rotates, the meshing transmission gear 1 63 and the gear 2 71 rotate, and the shaft 62 rotates synchronously with the gear 1 63, so that the "X"-shaped structure 64 drives the straight groove frame 65 to slide back and forth, and then the tooth plate 67 reciprocatingly meshes with the transmission gear sleeve 613, driving the gear sleeve 613 and the knocking roller 610 on the horn frame 1 69 to knock the steel bar surface back and forth. At the same time, the wave groove on the vibration plate 68 drives the horn frame 2 611 and the arc brush 612 to reciprocate left and right through the vibration rod 614. Sliding, by knocking and brushing the surface of the steel bars, the remaining floor slabs are further processed. Since the removed steel bars will have surface rust, the above-mentioned processing method will cause rusty metal scraps to be mixed in the recycled floor materials, affecting the quality of the reuse of the floor materials. Therefore, during the rotation of gear 2 71, the cylindrical head 72 slides along the inner surface of the slide 2 74, and the transmission swing frame 73 swings back and forth, so that the electromagnet 75 can absorb and separate the rusty metal scraps in the fallen residue.
