Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to a concrete separation grating. Background Technology

[0002] Concrete production is a common process for producing building materials. It is a hard material obtained by mixing, pouring, and curing components such as water, cement, aggregates, and admixtures. The concrete production process includes raw material preparation, aggregate processing, mixing and stirring, pouring, and curing.

[0003] Concrete production involves pouring aggregate stored in aggregate bins into a hopper, where it is screened by a grating screen and then discharged onto a conveyor belt for proportioning and mixing. However, large aggregate particles screened by the grating screen remain trapped at the top and cannot be discharged. Continuous feeding can easily lead to aggregate accumulation and jamming within the grating holes, affecting normal material conveying. Furthermore, it is inconvenient to adjust the screening gap according to the size of the aggregate. Therefore, we propose a concrete separation grating to solve this defect of the existing technology. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a concrete separation grating.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a concrete separation grid plate, comprising a frame base, a drive motor and a movable base respectively provided on the left and right sides of the frame base, a drive gear provided at the output shaft of the drive motor, a driven gear rotatably provided on the front side of the movable base, a drive belt meshing with the external of the drive gear and the driven gear, the drive belt passing through the frame base, and tooth blocks evenly provided on the external of the drive belt.

[0006] The rear surface of the frame base is provided with an adjustment groove, and multiple movable seats slide in the adjustment groove. The movable seats are fixed in the adjustment groove by locking members, and a roller rotates on the front side of the movable seats.

[0007] The upper front surface of the frame seat is provided with a directional groove, and a movable sleeve is rotatably fitted on the other end of the roller. The movable sleeve slides in the directional groove, and a rotating gear that meshes with the tooth block is provided at the same center on the other end of the roller.

[0008] By adopting the above technical solution, the loosely installed locking device facilitates the movement of the adjustable seat within the adjustment groove, driving the rollers and movable sleeve to move within the directional chute. This allows for easy adjustment of the gap between the rollers according to the size of the screened aggregate. After adjustment, aggregate is poured into the frame seat, falling onto the top of the rollers. The drive motor then rotates the drive gear, and the transmission belt is achieved through the meshing of the drive gear and the driven gear on the movable seat. During the transmission, the meshing of the toothed blocks on the transmission belt with the rotating gear drives the rollers to rotate clockwise synchronously. Aggregates of the correct size are discharged downwards through the gap between the rollers, while large aggregates are conveyed and discharged through the rotating rollers, preventing the accumulation of screened aggregates and the jamming of the rollers.

[0009] As a preferred technical solution of this utility model, the upper end of the frame seat is provided with a retaining frame through which the roller passes, wherein the retaining frame is set to open in the clockwise rotation direction of the roller.

[0010] By adopting the above technical solution, the setting of the enclosure frame prevents the aggregate from being discharged from the side of the frame seat, thereby allowing the aggregate to be discharged from the opening of the enclosure frame in a clockwise rotation direction.

[0011] As a preferred embodiment of this utility model, the locking member includes a nut disposed on the side of the movable seat, and the nut is internally threaded to a threaded locking rod with one end located in the adjusting groove.

[0012] By adopting the above technical solution, the threaded locking rod inside the nut is rotated to achieve threaded advancement of the threaded locking rod, thereby locking and fixing the movable seat.

[0013] As a preferred embodiment of this utility model, the threaded locking rod has a resistance-increasing block at one end located in the adjusting groove, and the resistance-increasing block has a resistance-increasing groove on its outside.

[0014] By adopting the above technical solution, the setting of the resistance-increasing block and resistance-increasing groove improves the locking and fixing effect.

[0015] As a preferred technical solution of this utility model, the upper end of the frame seat is provided with a limiting groove located outside the transmission belt.

[0016] By adopting the above technical solution, the transmission belt is positioned in a limited manner to prevent displacement.

[0017] As a preferred technical solution of this utility model, the upper end of the frame base is provided with a limiting strip connected to the enclosure frame. The limiting strip is inclined from bottom to top, located at the opening of the enclosure frame, and is the same width as the opening.

[0018] Using the above technical solution, the limiting strip restricts the discharge speed of the aggregate, while preventing small aggregate particles from splashing out.

[0019] As a preferred embodiment of this utility model, the front and rear sides of the enclosure frame are provided with through holes for the roller to pass through.

[0020] By adopting the above technical solution, it is ensured that the rotation of the roller will not be affected.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This concrete separation grating, through a loosely installed locking device, facilitates the movement of the adjustable seat within the adjustment groove, driving the rollers and movable sleeve to move within the directional chute. This allows for easy adjustment of the gap between the rollers according to the size of the screened aggregate. After adjustment, aggregate is poured into the frame seat, falling onto the top of the rollers. The drive motor then rotates the drive gear, and the transmission belt, through its meshing with the drive gear and the driven gear on the movable seat, achieves transmission. During transmission, the meshing of the toothed blocks on the transmission belt with the rotating gear drives the rollers to rotate clockwise synchronously. Aggregates of the correct size are discharged downwards through the gap between the rollers, while larger aggregates are conveyed and discharged through the rotating rollers, preventing aggregate accumulation and roller jamming. Compared to existing technologies, this method achieves adjustable screening based on aggregate size while avoiding aggregate accumulation and jamming. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1 to 6 In this embodiment, a concrete separation grid plate includes a frame base 1, on which a drive motor 4 and a movable base 2 are respectively fixed by bolts on the left and right sides. A drive gear 5 is fixed to the output shaft of the drive motor 4 by a coupling. A driven gear 3 rotates on the front side of the movable base 2. A transmission belt 6 meshes with the external of the drive gear 5 and the driven gear 3. The transmission belt 6 passes through the frame base 1, and tooth blocks 7 are fixed evenly at equal intervals on the outside.

[0032] An adjustment groove 8 is provided on the rear surface of the frame base 1. Multiple movable seats 9 slide in the adjustment groove 8. The movable seats 9 are fixed in the adjustment groove 8 by locking members. A roller 10 rotates on the front side. A directional sliding groove 11 is provided on the upper front surface of the frame base 1. A movable sleeve 12 is rotatably sleeved on the other end of the roller 10. The movable sleeve 12 slides in the directional sliding groove 11. A rotating gear 13 that meshes with the toothed block 7 is fixed at the same center on the other end of the roller 10.

[0033] The frame base 1 is the main support of the entire device. It is made of high-strength steel and has sufficient strength and stability to bear the weight of the aggregate and the operation of the transmission components. The drive motor 4 provides power to the drive gear 5. The tooth block 7 meshes with the rotating gear 13 to realize the transmission of power and drive the roller 10 to rotate.

[0034] The adjusting groove 8 is a long strip structure, set along the length of the frame seat 1. The movable seat 9 is placed in the adjusting groove 8 and can slide along the adjusting groove 8. A roller 10 is rotatably installed on the front side of the movable seat 9. The two ends of the roller 10 are connected to the movable seat 9 and the movable sleeve 12 respectively through bearings. The movable sleeve 12 is sleeved on the outside of the other end of the roller 10 and can slide in the directional slide groove 11. The directional slide groove 11 is opposite to the adjusting groove 8 and is used to limit the sliding direction of the movable sleeve 12 so that the roller 10 can maintain a stable position and posture when the movable seat 9 moves. A rotating gear 13 is provided at the center of the other end of the roller 10. The rotating gear 13 meshes with the toothed block 7 on the transmission belt 6. When the transmission belt 6 moves, it drives the rotating gear 13 to rotate, thereby realizing the synchronous clockwise rotation of the roller 10.

[0035] The locking component includes a nut and a threaded locking rod 17 located on the side of the movable seat 9. The nut is fixed to the rear side of the movable seat 9. One end of the threaded locking rod 17 is located in the adjusting groove 8, and the other end is threadedly connected to the nut. By rotating the nut, the threaded locking rod 17 can be screwed in or out of the nut. When the threaded locking rod 17 is screwed in until it is in close contact with the inner wall of the adjusting groove 8, the movable seat 9 is fixed in the adjusting groove 8. A resistance-increasing block is fixed to the end of the threaded locking rod 17 located in the adjusting groove 8. A resistance-increasing groove is opened on the outside of the resistance-increasing block. The setting of the resistance-increasing block and the resistance-increasing groove increases the friction between the threaded locking rod 17 and the inner wall of the adjusting groove 8, thereby improving the reliability of locking.

[0036] A baffle frame 14 is fixed to the upper end of the frame base 1. The baffle frame 14 is made of metal sheet and has a certain height and strength. It is used to prevent aggregate from being discharged from the side of the frame base 1. The baffle frame 14 is set with an opening facing the clockwise rotation direction of the roller 10, so that the aggregate can be discharged from the opening in the clockwise rotation direction. A limiting strip 15 connected to the baffle frame 14 is also fixed to the upper surface of the frame base 1. The limiting strip 15 is inclined from bottom to top, located at the opening of the baffle frame 14, and is the same width as the opening. The setting of the limiting strip 15 can limit the discharged aggregate, control the discharge speed, and prevent small particles of aggregate from splashing out. The front and rear side surfaces of the baffle frame 14 are provided with perforations for the roller 10 to pass through, ensuring that the roller 10 can rotate freely without affecting its normal operation.

[0037] The upper surface of the frame base 1 is provided with a limiting groove 16 located outside the transmission belt 6. The shape of the limiting groove 16 matches the shape of the transmission belt 6 and is used to limit the placement of the transmission belt 6 to prevent the transmission belt 6 from shifting or deviating during operation, ensuring the stable operation of the transmission belt 6, thereby ensuring the normal operation of the entire screening system.

[0038] It is equipped with a PLC-based automated control system to centrally control the operation of the concrete separation grating.

[0039] Working principle and usage steps:

[0040] The concrete separation grating is fixed at the aggregate conveying position in concrete production. The frame seat 1 is placed stably and connected to the feeding hopper and conveyor belt. The power supply of the drive motor 4 is turned on, and the rotation direction of the motor is checked to ensure that the meshing transmission of the drive gear 5 and the driven gear 3 is normal. According to the aggregate particle size requirements, the threaded locking rod 17 is rotated to loosen it, and the position of the moving seat 9 in the adjustment groove 8 is adjusted to adjust the screening gap between the rollers 10. During the adjustment process, the position of the movable sleeve 12 in the directional slide 11 is moved synchronously to ensure the horizontality and stability of the rollers 10. After the adjustment is completed, the threaded locking rod 17 is rotated to tighten it, so that the moving seat 9 is fixed in the adjustment groove 8.

[0041] Start the drive motor 4, which drives the drive gear 5 to rotate. Through the transmission belt 6, the driven gear 3 rotates synchronously. During operation, the toothed blocks 7 on the outside of the transmission belt 6 mesh with the rotating gear 13 at the end of the roller 10, causing the roller 10 to rotate clockwise synchronously. The aggregate is poured into the frame seat 1 and falls above the roller 10. The aggregate of the screened particle size is discharged downward through the gap between the rollers 10 under the action of the rotation of the rollers 10 and falls onto the conveyor belt for the next step of proportioning and mixing. The granular aggregate is driven by the rollers 10 and moves clockwise to the opening of the enclosure frame 14. Under the action of gravity and inertia, it is discharged to the designated position to avoid the accumulation and jamming of the screened aggregate between the rollers 10. The limiting strip 15 makes the discharged aggregate discharge along the inclined surface, reducing the discharge speed and preventing small granular aggregate from being discharged synchronously.

[0042] Beneficial effects: By adjusting the position of the movable seat 9 within the adjusting groove 8, the screening gap between the rollers 10 can be easily adjusted to adapt to the screening requirements of aggregates of different particle sizes, improving the versatility and flexibility of the equipment. The synchronous clockwise rotation of the rollers 10 ensures that the aggregates are uniformly turned and stirred during the screening process, accelerating the screening process and improving screening efficiency. At the same time, large aggregates can be smoothly discharged, avoiding clogging of the screening holes and accumulation of aggregates, ensuring the continuity and stability of the screening operation.

[0043] Aggregates of the correct size are discharged through the gap between the rollers 10, ensuring the uniformity of aggregate size after screening, improving the mix proportion accuracy and quality stability of concrete. The setting of the limiting strip 15 effectively controls the discharge speed of aggregates, avoiding the discharge of small aggregate particles together and causing waste of aggregates.

[0044] The threaded structure design of the locking component makes the adjustment and fixing of the movable seat 9 simple and convenient, without the need for complicated tools and cumbersome steps. The cooperation between the resistance block and the resistance groove enhances the reliability of the locking and reduces the loosening phenomenon after adjustment.

[0045] In summary, the concrete separation grating in this embodiment has high-efficiency screening performance, good aggregate quality control, stable operational reliability, convenient operation and maintenance, and significant energy-saving, environmental protection and economic benefits. It can effectively solve the problems existing in aggregate screening in current concrete production and is a high-performance and highly practical concrete production equipment.
