Description

Technical Field

[0001] The invention relates to the technical field of construction waste sorting and processing equipment, in particular to a hopper for a construction waste sorting assembly line and an operating method thereof. Background Art

[0002] Many wastes in construction waste can be reused as renewable resources after sorting, removal or crushing. Coarse and fine aggregates produced from waste construction concrete and waste bricks and stones can be used to produce concrete and mortar of corresponding strength grades or to prepare building materials such as blocks, wall panels, and floor tiles. After adding curing materials, coarse and fine aggregates can also be used for highway pavement base. Aggregates produced from waste bricks and tiles can be used to produce recycled bricks, blocks, wall panels, floor tiles and other building materials. When using the construction waste sorting line, first use a grab excavator to put the construction waste into a chain feeder or a vibrating feeder, and then achieve uniform feeding.

[0003] However, a hopper is directly set on the traditional chain loading machine, and uniform loading is achieved by rotating the chain and coordinating the gap of the hopper. The material is easily temporarily stuck in the gap between the chain and the hopper, affecting the mixing uniformity of the loading. When the jam is serious, manual cleaning is required, affecting the operating efficiency. Most of them directly fix a scraper at the bottom of the chain to remove the material stuck on the chain. When a lot of material is stuck on the scraper, it affects the cleaning effect of the chain. Summary of the invention

[0044] Specifically, the cleaning structure 7 includes an outer frame 701, the outer frame 701 is slidably provided on the chain plate feeder body 1, a transmission plate 802 is slidably provided on the top of the outer frame 701, a cleaning plate 801 is fixed to the end of the transmission plate 802, the cleaning plate 801 is in contact with the bottom end of the chain plate 3, a hydraulic cylinder 803 is provided between the transmission plate 802 and the outer frame 701, a storage box 702 is slidably provided inside the outer frame 701, a filter box 708 is provided inside the storage box 702, a drain pipe 707 is fixed to the bottom end of the storage box 702, a slide 703 is provided on the outer frame 701, and the slide 70 3 is provided with a high-pressure nozzle 706 inclined toward the cleaning plate 801, a guide rod 705 of a T-shaped structure is fixed on the outer frame 701, the slide 703 is slidably connected with the guide rod 705, a spring 704 is provided between the slide 703 and the guide rod 705, the right side of the cleaning plate 801 is triangular, a hot air blower 709 is provided on the outer frame 701, the exhaust port of the hot air blower 709 corresponds to the exhaust hole 710 on the outer frame 701, the transmission plate 802 slides to the left without blocking the exhaust hole 710, and the transmission plate 802 slides to the right so that the through hole on the transmission plate 802 and the exhaust hole 710 are staggered;

[0045] When cleaning the waste on the chain plate 3, the hydraulic cylinder 803 is in a retracted state, and the hydraulic cylinder 803 drives the transmission plate 802 to slide to the right, so that the through hole on the transmission plate 802 is staggered with the exhaust hole 710, to prevent the hot air blower 709 from accumulating dust when not in use.

When the cleaning structure 7 needs to be inspected and maintained, the handle 902 is rotated, and the handle 902 drives the screw rod 901 to rotate, so that the screw rod 901 thread drives the clamping block 903 to slide upward, without limiting the outer frame 701, and then the outer frame 701 can be slid out for inspection and maintenance. Two handles 902 are provided to facilitate operators with different operating habits to drive the screw rod 901.

[0048] A hopper for a construction waste sorting line comprises the following steps:

[0049] S1: First, use a grab excavator to put the construction waste into the feed hopper 4, and then the driving structure 2 drives the chain plate 3 to rotate to realize the feeding of the construction waste;

[0050] S2: The driving structure 2 drives the feeding structure 5 to work, so that the feeding structure 5 pushes the construction waste to move to the left, and at the same time, the feeding structure 5 drives the anti-blocking structure 6 to realize the oblique upward movement of the waste;

[0051] S3: The waste chips on the chain plate 3 are removed by the cleaning structure 8, and the chain plate 3 and its cleaning structure 8 are cleaned in cooperation with the cleaning structure 7.

[0052] When the present invention is in use, a grab excavator is used to put construction waste into the feed hopper 4, and then the motor 203 is started (a PLC controller is installed on the chain plate feeder body 1 to control the electrical components), and the first pulley 204 on the motor 203 drives the first pulley 204 on the driving roller 201 to rotate through the first belt 202, so that the driving roller 201 drives the chain plate 3 to rotate, and the rotation of the chain plate 3 drives the middle driving roller 201 to rotate, so that the middle driving roller 201 drives the second pulley 501 to rotate, and the second belt 502 is transmitted, so that the second pulley 501 on the driving shaft 503 rotates, and the driving shaft 503 rotates, and the driving shaft 503 drives the transmission wheel 504 to rotate, and the first roller 505 on the transmission wheel 504 rolls on the transmission groove 506, thereby driving the driving block 507 to slide back and forth, and the driving block 507 drives the push block 508 to slide back and forth, thereby regularly pushing the construction waste to move toward the left side, preventing the construction waste from being stuck in the gap between the feed hopper 4 and the chain plate 3, and improving the quality of the feeding;

[0053] At the same time, when the push block 508 moves to the left, the second roller 604 on the slide plate 602 moves in the parallel section of the slide groove 605. At this time, the anti-blocking plate 601 pushes the construction waste vertically. When the second roller 604 rolls in the arc section of the slide groove 605, the anti-blocking plate 601 rotates clockwise, so that the anti-blocking plate 601 pushes the construction waste to move to the upper left, further preventing the construction waste from being blocked between the feed hopper 4 and the chain plate 3, greatly improving the conveying quality.

[0054] When cleaning the waste on the chain plate 3, the hydraulic cylinder 803 is in a retracted state, and the hydraulic cylinder 803 drives the transmission plate 802 to slide to the right, so that the through hole on the transmission plate 802 is staggered with the exhaust hole 710, to prevent the hot air blower 709 from accumulating dust when not in use. At the same time, the right side of the cleaning plate 801 is triangular, which is convenient for pushing the slide 703 to slide downward. The slide 703 is slidably connected with the guide rod 705, and the resistance spring 704 is compressed, so that the slide 703 and the cleaning plate 801 are in resistance, which effectively prevents the waste cleaned by the cleaning plate 801 from entering the outer frame 701;

Then the solenoid valve is turned on, so that water is tiltedly sprayed from the high-pressure nozzle 706 to flush the chain plate 3 and the cleaning plate 801, preventing too much waste from sticking to the cleaning plate 801 and affecting the cleaning effect. At the same time, the chain plate 3 is flushed to make the cleaning effect of the chain plate 3 better, and the flushing water flows into the filter box 708 The waste is then stored in the filter box 708, and the water is discharged from the drain pipe 707. When the chain plate 3 needs to be dried, the hot air blower 709 is turned on to discharge the air flow from the exhaust hole 710 to dry the chain plate 3. After the storage box 702 is pulled out, the filter box 708 can be taken out to clean the waste. When the cleaning structure 7 needs to be inspected and maintained, the handle 902 is turned, and the handle 902 drives the screw rod 901 to rotate, so that the screw rod 901 thread drives the block 903 to slide upward, without limiting the outer frame 701, and then the outer frame 701 can be slid out for inspection and maintenance. Two handles 902 are provided to facilitate operators with different operating habits to drive the screw rod 901.
