Description

Technical Field

[0001] The present application relates to the technical field of aggregate separation, and in particular to a concrete aggregate separation device. Background Art

[0002] Concrete aggregate refers to the loose granular material that acts as a skeleton or filling in concrete. Concrete aggregate is usually divided into coarse aggregate and fine aggregate. When pouring concrete, the diameter of the concrete aggregate is usually required to be within a certain range. If some aggregates are mixed with larger diameter aggregates, it will affect the quality of the concrete.

[0003] In the related art, a concrete aggregate separation device comprises a conveyor belt, a separation box is arranged below the conveyor belt, a placement groove is opened on the end surface of the separation box, a filter screen is arranged on the groove wall of the placement groove, and the filter screen can filter aggregates with larger diameters.

[0004] When aggregates pass through the filter, aggregates with larger diameters are not easy to pass through, so some of the aggregates with larger diameters are located on the filter. When the number of aggregates to be filtered is large, more aggregates with larger diameters will accumulate on the filter, so that the holes on the filter are blocked by the aggregates, making it difficult for the aggregates that can pass through to pass through the filter. Summary of the invention

[0005] In order to improve the problem that an aggregate separation device may be clogged by aggregate when processing excessive aggregate, the present application provides a concrete aggregate separation device.

[0006] The present application provides a concrete aggregate separation device, which adopts the following technical solution:

[0007] A concrete aggregate separation device comprises a conveyor belt and a separation box, wherein the separation box is located below the conveyor belt, a placement groove is provided on the end surface of the separation box, a separation structure is provided in the placement groove, the separation structure comprises a rotating roller, a plurality of placement bars and a driving assembly, the driving assembly is used to drive the rotating roller to rotate, the rotating roller is arranged in the placement groove, the rotation direction of the rotating roller is the same as the rotation direction of the conveyor belt, the position where the aggregate falls is located between the axis of the rotating roller and the conveyor belt, and the aggregate falls into the placement groove, a plurality of the placement bars are all arranged on the outer surface of the rotating roller, a plurality of the placement bars are distributed along the axial direction of the rotating rod, and the aggregate passes through the placement bars when falling, a plurality of fixing rods are provided on the placement bars, the gap between two adjacent fixing rods is provided for the required aggregate to pass through, the end surface of the fixing rod away from the placement bar abuts against the groove wall of the placement groove, and a perforation and a through hole are provided on the bottom wall of the placement groove, the perforation is provided for the required aggregate to fall, and the through hole is provided for the aggregate with a larger diameter to fall.

[0008] By adopting the above technical scheme, the aggregate falls from the conveyor belt into the placement groove. The fixed rod restricts the aggregate so that the required aggregate can pass between two adjacent fixed rods and fall between the perforations. At the same time, it is not easy for the aggregate with a larger diameter to pass between two adjacent fixed rods, so that the aggregate is fixed by the fixed rod. In addition, the rotation direction of the rotating roller is opposite to that of the conveyor belt, so that the rotating roller can drive the aggregate with a larger diameter to other places to fall, so that aggregates with different diameters can be distinguished, and the aggregate with a larger diameter can be transported to other places without affecting the subsequent separation. Since the aggregate can abut against the fixed rod when falling from the conveyor belt, it is not easy for the aggregate to fall directly from the placement groove to the perforation direction without being screened by the fixed rod. By the aggregate falling from the perforations and through holes, it is not easy for the aggregate to form accumulation in the placement groove, so that the separation structure can continuously screen the aggregate.

[0009] Optionally, a movable groove is provided on the outer circumferential surface of the rotating roller, and the movable groove extends to the end surface of the rotating roller. The placement bar is slidably connected in the movable groove, and a locking piece is provided on the placement bar, and the locking piece is used to fix the placement bar in the movable groove.

[0010] By adopting the above technical solution, the placement bar slides in the movable groove, and the locking piece limits the placement bar in the movable groove, so that the placement bar can be replaced on the rotating roller, so that the staff can select a suitable placement bar, that is, select the distance between two adjacent fixed rods on the placement bar, so that the fallen aggregate can be screened so that the required aggregate can pass between the two adjacent fixed rods.

[0011] Optionally, the locking member includes a fixed cover, a spring and a card block, a side of the fixed cover is provided with a receiving groove, one end of the spring is arranged on the bottom wall of the receiving groove, the other end of the spring is arranged on the card block, and a card slot for the card block to be embedded is provided on the slot wall of the movable slot, and when the card block is embedded in the card slot, the spring is in a compressed state.

[0012] By adopting the above technical solution, the spring is in a compressed state, so that the spring applies a force to the block, causing the block to move in a direction away from the spring, making it difficult for the block to escape from the slot, thereby allowing the fixed cover and the slot wall of the movable slot to be fixed to each other, making it difficult for the fixed cover to escape from the movable slot, and allowing the fixed rod to restrict the placement bar, making it difficult for the placement bar to escape from the movable slot in the penetrating direction of the movable slot.

[0013] Optionally, a guide groove is provided on the groove wall of the placement groove, and the guide groove penetrates to the end surface of the separation box, and a guide rod capable of being embedded in the guide groove is provided on the end surface of the rotating roller.

[0014] By adopting the above technical solution, the guide rod slides on the guide groove, so that the rotating roller is not easily offset when installed in the placement groove, so that the fixed rod on the rotating roller can maintain contact with the wall of the placement groove, so that the falling aggregate always passes through the fixed rod, maintaining the screening effect of the fixed rod on the aggregate.

[0015] Optionally, the driving assembly includes a support plate, a motor and a rotating rod, the support plate is arranged on the end face of the separation box, the motor is used to drive the rotating roller to rotate, the motor is detachably connected to the support plate, the rotating rod is arranged on the rotating roller, and the rotating rod passes through the separation box and is connected to the driving shaft of the motor.

[0016] By adopting the above technical solution, the motor is supported by the support plate, so that the motor can be arranged outside the separation box; the motor drives the rotating rod to rotate, and the rotating rod is arranged on the rotating roller, so that the motor can drive the rotating roller to rotate, so that the rotating roller can screen the aggregate.

[0017] Optionally, a dust cover is provided on the end face of the separation box, and the dust cover is used to completely cover the opening of the placement groove. A drop hole for aggregate to fall is opened on the end face of the dust cover, and a fixing piece is provided on the dust cover, and the fixing piece is used to fix the dust cover to the separation box.

[0018] By adopting the above technical scheme, when the aggregate rotates or falls in the placement trough, the dust generated by the aggregate is not easy to drift out of the placement trough through the dustproof cover covering the placement trough, so that the dust can be located in the placement trough, so that the dust is not easy to pollute the external environment; when the rotation speed of the rotating roller is fast, the aggregate may fly out of the placement trough due to the excessively fast rotation speed, so that the aggregate falls out of the placement trough and falls to the outside, causing the loss of aggregate and the dirty environment, and may be dangerous to the staff. When the dustproof cover covers the placement trough, the aggregate is not easy to fly out of the placement trough due to the rotation of the rotating roller.

[0019] Optionally, the fixing part includes a slider, and a sliding groove for sliding the dust cover is provided on the end face of the separation box, the sliding groove passes through the end face of the separation box, and a sliding groove for sliding the slider is provided on the groove wall of the sliding groove, and when the slider is set in the sliding groove, the dust cover is not easy to detach from the separation box.

[0020] By adopting the above technical solution, the dust cover slides in the sliding groove, and the slider slides in the sliding groove, so that the slider is not easy to separate from the sliding groove, and the dust cover is not easy to separate from the separation box, so that the dust cover can cover the opening of the placement groove, so that dust is not easy to separate from the placement groove.

[0021] Optionally, a linkage assembly is provided on the end surface of the dust cover, and the linkage assembly is used to limit the dust cover from being easily opened when the rotating roller rotates.

[0022] By adopting the above technical solution and limiting the linkage assembly, the dust cover is not easily opened when the rotating roller rotates, so that when the dust cover is opened, the rotating roller stops rotating. At this time, the aggregate on the rotating roller is not easily flown out of the placement groove due to the lack of the dust cover, so that the staff is not easily in danger due to the flying aggregate when opening the dust cover; at the same time, the possibility of dust generated by rotation drifting out of the placement groove is reduced, so that the external environment is not easily polluted.

[0023] Optionally, the linkage assembly includes a linkage block and a linkage ring, a linkage groove is provided on the outer circumferential surface of the rotating rod, a linkage bar is slidably connected in the linkage groove, the linkage block is arranged on the dust cover, a rotating hole is provided on the end face of the linkage block for the rotating rod to pass through, an annular groove is provided on the hole wall of the rotating hole, the linkage ring is arranged in the annular groove, the linkage ring is for the rotating rod to pass through, and a stop groove is provided on the inner wall of the linkage ring facing the dust cover for the linkage bar to be embedded in.

[0024] By adopting the above technical scheme, the linkage ring is in the ring groove, so that the linkage block and the linkage ring are in a rotational connection, so that the linkage block is not easily affected when the linkage ring rotates; since a stop groove is provided on the inner wall of the linkage ring, when the linkage ring is not subjected to external force, the weight of the side of the linkage ring with the stop groove is smaller, so that the stop groove can be located at the top, and when the rotating rod rotates, the linkage bar moves toward the outside of the rotating rod due to centrifugal force. At this time, the linkage bar can be embedded in the stop groove, so that the rotating rod and the linkage ring are fixed to each other, so that the rotating rod can drive the linkage ring to rotate together, and since the linkage ring is rotationally connected in the linkage block, it is not easy for the rotating rod and the linkage block to move, and the dust cover is not easy to move when the rotating rod rotates, so that the rotating rod limits the movement of the dust cover; when the rotating rod does not rotate, since the linkage ring has a stop groove, one side of the stop groove is located at the top, so that the linkage bar can be affected by gravity and disengage from the stop groove.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Aggregates are moved into the placement trough through the conveyor belt and pass between two adjacent fixed rods, so that aggregates with different diameters can be separated. In addition, the rotation of the rotating roller causes the aggregate with a larger diameter to be driven by the rotating roller to move to another place and then pass through the through hole. At the same time, the aggregate with a smaller diameter falls along the gap between the two fixed rods until it passes through the through hole, making it difficult for the aggregates to accumulate on the separation structure, so that the separation structure can smoothly separate aggregates of different diameters.

[0027] 2. The placement bar slides in the movable groove and the locking piece locks the placement bar, so that the placement bar can be replaced in the movable groove, so that the staff can choose the distance between two adjacent fixed rods, that is, choose the appropriate placement bar, so that the screened aggregate can be adjusted.

[0028] 3. Since the linkage bar is embedded in the stop groove, the linkage bar and the linkage ring are fixed to each other, so that the rotating rod and the linkage ring can be firmly connected. In addition, the linkage ring is rotatably connected to the linkage block, so that when the rotating rod drives the linkage ring to rotate, it is not easy to affect the linkage block, and the linkage block and the rotating rod are more reliable; when the linkage ring is not subjected to external force, the side of the linkage ring with the stop groove is located at the top, making it difficult for the linkage bar to be embedded in the stop groove due to gravity. The linkage bar can only be embedded in the stop groove due to the centrifugal force when the rotating rod rotates, so that the linkage ring can be separated from the rotating rod when the rotating rod is not rotating.
