Description

Technical Field

[0002] Housing construction projects refer to the construction of buildings and structures on land, including new construction, reconstruction, expansion, demolition and other projects. Such projects will generate a large amount of waste materials during the construction process, such as concrete blocks, brick and tile fragments, wood, plastic, metal, etc. Traditionally, these waste materials are often mixed and piled up, which not only occupies a large amount of land resources, but also causes serious pollution to the environment. Therefore, how to effectively classify and recycle these waste materials has become a problem that needs to be solved urgently in the construction industry.

[0003] According to the patent document: CN216679048U, a construction waste classification and recycling device is disclosed, which belongs to the field of construction engineering technology, including a first box body, a second box body is fixedly installed on the upper side wall of the first box body, a feed hopper is fixedly installed on the upper side wall of the second box body, and a third box body is fixedly installed on the right side wall of the first box body. The debris in the construction waste passes through the mesh into the interior of the third box body, and then the construction waste on the surface of the mesh is pushed from the interior of the third box body to the interior of the first box body through the push plate. Large parts of construction waste can be recycled and reused. The debris in the construction waste can be collected in a centralized manner through the third box body and then processed in a centralized manner. By centralized processing of waste, the impact on the environment is avoided, which has an environmental protection effect. The construction waste is classified, recycled and processed through the first box body and the third box body, which improves the recycling rate of construction waste, saves costs, and makes the process of construction waste processing more convenient.

The top and the bottom of the inner sides of the two sets of hinge plates 315 are provided with hinge grooves 316. The top of the discharge pipe 311 is aligned with the bottom of the discharge trough 219. The two control panels 32 each include a control side panel 321. The top and the bottom of the outer sides of the two control side panels 321 are rotatably connected with two rotating rods 322. The four groups of rotating rods 322 are rotatably connected to the side of the control side plate 321 with a two-way hinged rod 323, the four groups of two-way hinged rods 323 are rotatably connected to the side of the rotating rod 322 with a second rotating rod 324, the inner sides of the four groups of second rotating rods 324 away from the two-way hinged rod 323 are rotatably connected to the opening and closing plates 328, the middle parts of the outer walls of the four groups of two-way hinged rods 323 are rotatably connected to the inner walls of the four groups of hinged grooves 316, and the inner bottoms of the two control side plates 321 are fixedly connected to the magnetic absorbers 326, a magnetic absorber moving groove 327 is provided on one side of the two opening and closing plates 328 and the magnetic absorber 326, an opening and closing plate top connecting block 325 is fixedly connected to the middle of the top of the two opening and closing plates 328, the outer walls of the two opening and closing plate top connecting blocks 325 are respectively fixedly connected to the inner sides of the two third hydraulic push rods 318, and the inner tops of the two opening and closing plates 328 are fixedly connected to the cover plates 329, the inner sides of the two cover plates 329 are fitted, and the bottoms of the two cover plates 329 are movably connected to the top of the discharge pipe 311;

[0036] After the stones and the steel bars are separated, they are transferred to the material discharge chute 219 together. At this time, the two third hydraulic push rods 318 are activated, pulling the top connection block 325 of the opening and closing plate, thereby driving the opening and closing plate 328 and the cover plate 329 to move outward, thereby releasing the connection between the material discharge chute 219 and the top of the material discharge pipe 311, so that the stones can fall into the crushed stone collection bin 4 through the material discharge chute 219 and the material discharge pipe 311;

[0037] When the opening and closing plate 328 moves outward, the front and rear two sets of second rotating rods 324 push the two-way hinged rod 323 to rotate on the inner wall of the hinge groove 316, and the rotating rod 322 is pushed by the two-way hinged rod 323, so that the rotating rod 322 pushes the control side plate 321 and the magnetic absorber 326 to move toward the inner side of the opening and closing plate 328.

The separated steel bars are guided into the steel bar collection bin 312 through the coordinated action of the two side plate connecting blocks 313 and the side plates 314.

[0038] Working principle: When it is necessary to separate the waste concrete slab, first place the waste concrete slab on the top of the conveyor crawler 213 on the inner wall of the automatic conveying sleeve 212, and convey the concrete slab to the inner wall of the feeding platform 211 through the conveyor crawler 213, and then start the hydraulic push rod 216 to pull the push plate push-pull block 217 to slide on the inner wall of the slide 214, thereby driving the push plate 218 to push the slab to the bottom of the crushing plate 2211. At this time, start the second hydraulic push rod 223 to drive the crushing plate 2211 to push downward. When the crushing plate 2211 moves downward, the crushing plate 2211 passes through the crushing plate 2211. The two crushing plate connecting rods 2210 slide on the outer wall of the sliding rod 228, thereby ensuring the stability and orientation of the crushing plate 2211 when moving downward, and the sliding rod 227 slides on the inner wall of the sliding rod connecting block 224 to further strengthen the stability when moving downward. The crushing plate 2211 moves downward to press the stone slab on the top of the feeding platform 211, and then the stone slab is crushed and separated, so that the stone slab is broken and the steel bars inside are exposed. After that, the hydraulic push rod 216 drives the push plate 218 to reset, and the next stone slab is placed on the inner wall of the automatic conveying sleeve 212 and the above steps are continued for conveying;

[0039] When the separated stones and steel bars are transported to the material discharge chute 219 together, at this time, the two third hydraulic push rods 318 are started to pull the top connecting block 325 of the opening and closing plate to drive the opening and closing plate 328 and the cover plate 329 to move outward, thereby releasing the connection between the material discharge chute 219 and the top of the material discharge pipe 311, and the stones can fall into the crushed stone collection bin 4 through the material discharge chute 219 and the material discharge pipe 311. When the two opening and closing plates 328 move outward, at this time, the two-way hinged rod 323 is pushed in the hinged groove 3 by the second rotating rods 324 of the front and rear two groups. The inner wall of 16 rotates, thereby pushing the rotating rod 322 through the bidirectional hinged rod 323, so that the rotating rod 322 pushes the control side plate 321 and the magnetic absorber 326 to move toward the inner side of the two opening and closing plates 328. At this time, the two magnetic absorbers 326 are started to clamp the stones and steel bars falling from the inner wall of the discharge pipe 311, and the steel bars are adsorbed on the surfaces of the two magnetic absorbers 326, thereby realizing the separation of the stones and the steel bars. The separated steel bars are guided into the steel bar collection bin 312 through the joint action of the two side plate connecting blocks 313 and the side plates 314.
