Description

Technical Field

[0001] This utility model relates to the technical field of recycled aggregate processing, specifically a feeding mechanism for processing recycled aggregate from construction waste. Background Technology

[0002] Recycled aggregate refers to aggregate made from mixed fill soil that has been screened and processed by machines into small particles. It is commonly used in construction waste processing and is transported by conveyor.

[0003] When transporting recycled aggregate from construction waste using existing conveyors, the recycled aggregate tends to accumulate in the center of the conveyor belt, causing a depression in the center. Over time, this depression can deform the conveyor belt, leading to unstable conveying.

[0004] In related technologies, please refer to Chinese Patent No. CN221776767U, which specifically discloses a feeding mechanism for processing recycled aggregates from construction waste. When using this feeding mechanism for processing recycled aggregate from construction waste, the limiting plate is inserted into the loading chamber, and the through slot is aligned with the connecting hole. The through shaft is inserted into the connecting hole and the through slot, and the two end seats are respectively threaded to the external threads at both ends of the through shaft, which limits the through shaft and prevents it from falling. When feeding recycled aggregate from construction waste, the recycled aggregate falling on the conveyor belt is separated by the partition plate and falls into multiple loading chambers, avoiding large-area accumulation in the center of the conveyor belt and preventing the problem of depression and deformation in the center of the conveyor belt, thereby improving service life and conveying stability. When tilting is required, only the fixed plate of the raised end needs to be removed to remove the support leg, replace it with the support leg of the required height, and fix it back to the support plate. The support leg is rotatably connected to the rotating shaft through ball bearings to realize angle adjustment and improve flexibility. When tilting, the aggregate inside the loading chamber will slide backward, and the limiting plate will separate the loading chamber again, thereby limiting the aggregate and preventing it from sliding, improving the stability of tilting conveying.

[0005] The applicant discovered shortcomings in the aforementioned feeding mechanism for processing recycled aggregates from construction waste: although the aggregates are separated by partition plates and fall into multiple loading cavities to avoid large-area accumulation at the center of the conveyor belt and prevent the conveyor belt from sinking and deforming, thereby improving service life and conveying stability, there are still shortcomings in actual use. For example, when the aggregates are fed onto the conveyor belt, although the aggregates can be automatically dispersed to a certain extent, the aggregates do not have a weighted feeding structure, which makes it easy for the aggregates falling onto the conveyor belt to accumulate unevenly. At this time, the weight distribution of aggregates at different positions on the conveyor belt is large, which affects the conveying effect of the conveyor belt.

[0006] In view of this, this technical solution proposes a feeding mechanism for processing recycled aggregates from construction waste, which can better solve the problems mentioned above.

[0007] Utility model content.

[0008] The technical solution adopted by this utility model is as follows: A feeding mechanism for processing recycled aggregate from construction waste includes a set of conveyor belt frames and several transmission rollers rotatably installed between the set of conveyor belt frames. A conveyor belt is adapted to surround the transmission rollers. A first motor is arranged on the left side of the front conveyor belt frame, and the output end of the first motor is connected to the left transmission roller. Protective plates for limiting the aggregate are arranged in front and behind the conveyor belt. A partition plate for separating the aggregate is arranged on the transmission roller inside the protective plate. A limiting plate for further separating and pushing the aggregate is arranged between the protective plate and the partition plate and between the partition plates.

[0009] A support plate is fixed to the top left side of each of the conveyor belt frames, and a material distribution bin is fixed to the top of the support plate. A storage bin for storing aggregates is fixed above the material distribution bin. A discharge port is connected to the bottom of the material distribution bin. A distributor is rotatably installed inside the material distribution bin, and a second motor is provided on the outside of the material distribution bin to drive the distributor inside the material distribution bin.

[0010] A fixed frame is fixed on the top of a set of conveyor belt frames on the right side of the material distribution bin, and a smoothing plate for smoothing up the aggregate is slidably installed on the inner side of the fixed frame. A threaded rod is threadedly connected to the upper middle position inside the fixed frame, and the bottom end of the threaded rod is rotatably installed with the smoothing plate.

[0011] In a preferred embodiment, the protective plate and the separator are heat-fused to the conveyor belt, and the protective plate and the separator are of the same specifications.

[0012] In a preferred embodiment, the number of the partition plates is two, and the partition plates and the protective plates cooperate to divide the conveyor belt into three loading cavities.

[0013] In a preferred embodiment, the limiting plate is at the same height as the protective plate and the separator on the side away from the conveyor belt.

[0014] In a preferred embodiment, the distributor consists of a rotating shaft and a distributing plate, the distributing plate being fixed at equal intervals on the rotating shaft, and the distributing plate being adapted to the interior of the distributing bin.

[0015] In a preferred embodiment, the second motor is located outside the material distribution bin, and the connection between the output end of the material distribution bin and the material distributor drives the material distributor to rotate and distribute materials.

[0016] In a preferred embodiment, a sliding groove is provided on the inner side of the fixing frame at a relatively opposite position, and a slider is movably inserted into the sliding groove to be fixedly connected to the front and rear of the material plate and to limit and guide the material plate.

[0017] In a preferred embodiment, a threaded hole is provided in the upper center of the fixing frame, and a threaded rod is threaded into the threaded hole. A handle for rotating the threaded rod is fixed to the upper end of the threaded rod.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates better distribution and falling of aggregates, making it less likely for aggregates to accumulate excessively, and it can smooth out the joined aggregates, better ensuring the stability of the conveyor belt in conveying aggregates, thus protecting the conveyor belt.

[0019] 1. In this utility model, by first rotating the threaded rod, the threaded rod drives the material-supporting plate to move downward, thereby moving the bottom of the material-supporting plate to a position close to the top of the partition plate.

[0020] 2. In this utility model, the first motor and the second motor are started to pour the aggregate into the storage bin. At this time, the second motor drives the distributor to divide the aggregate into smaller pieces. The aggregate falls through the discharge port onto the conveyor belt and is transported separately with the cooperation of the protective plate, the partition plate, the limit plate and the support plate. When the aggregate is higher than the partition plate, the smoothing plate can smooth the aggregate onto the conveyor belt, thus ensuring the stability of the conveyor belt in transporting the aggregate.

The limiting plate 7 is at the same height as the side of the protective plate 5 and the partition plate 6 away from the conveyor belt 3.

[0028] refer to Figure 1-2 As shown, a set of conveyor belt frames 1 are all fixed with support plates 8 on the top left side, and a material distribution bin 9 is fixed at the top of the support plate 8. A storage bin 10 for storing aggregate is fixed above the material distribution bin 9. A discharge port 11 is connected to the bottom of the material distribution bin 9.
