Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete raw material storage technology, specifically to an aggregate bin for a concrete batching machine. Background Technology
[0002] Concrete is characterized by abundant raw materials, low price, and simple production process, which leads to its increasing use. Aggregate is a granular loose material that plays a skeleton or filling role in concrete. As the main raw material in concrete, aggregate is divided into coarse aggregate and fine aggregate. Before being transferred, aggregate needs to be stored in aggregate bins.
[0003] A concrete aggregate silo, disclosed in patent number "CN218518932U", includes a silo body with grooves at both its left and right ends. An inner silo is slidably connected to the inner cavity of the silo body. Discharge pipes are installed at both the left and right ends of the inner silo, and these pipes are slidably connected to the grooves. A rack is installed at the lower end of the inner silo. An opening is located on the lower wall of the silo body, directly below the rack. A gear is movably connected to the rear wall of the inner cavity of the silo via a rotating shaft. The gear meshes with the rack. Several springs are installed between the lower wall of the inner silo and the lower wall of the inner cavity of the silo body. These springs are symmetrically distributed about the rack. The inner silo, springs, rack, gear, rotating shaft, pointer, and dial work together to display the amount of aggregate in the inner silo.
[0004] However, the above-mentioned device still has the following problems during implementation:
[0005] 1. Most existing concrete batching machines lack aggregate mixing devices in their aggregate bins. After feeding, the aggregate bins accumulate and clump together during long-term storage. If mixing and stirring are not performed during feeding, it may cause blockage. Furthermore, feeding directly with a large amount of clumps may affect the performance.
[0006] 2. Most existing concrete batching machines do not have a screen plate structure for feeding aggregates, which will cause impurities to be mixed in the aggregates. If the impurities cannot be cleaned during feeding, it will affect the use of subsequent aggregates. Utility Model Content

[0029] Example 1:
[0030] An aggregate bin for a concrete batching machine includes a base plate 1 and a bin body 6. Two sets of vertical plates 2 are symmetrically and fixedly installed on both sides of the upper surface of the base plate 1. The bin body 6 is located above the base plate 1 and between the two sets of vertical plates 2. A drive motor 3 is symmetrically and fixedly installed on one side of each of the two sets of vertical plates 2. A rotating shaft 4 is fixedly installed at the output end of the drive motor 3. A positioning block 5 is provided at one end of the rotating shaft 4. A fixing ring 601 is fixedly installed on the upper part of the bin body 6.

[0031] A support plate 8 is slidably connected to the upper surface of the base plate 1. A material discharge chamber 602 is provided at the lower part of the silo body 6. A screening plate 9 is provided inside the material discharge chamber 602. The aggregate is screened by the screening plate 9 to make the material discharge uniform.
[0032] Support blocks 10 are fixedly installed on both sides of the outer wall of the fixed ring 601 away from the protrusion 7. A drive box 11 is fixedly installed on the upper surface of the support block 10. A push rod 12 is fixedly connected to the output end of the drive box 11. A connecting plate 13 is fixedly connected to the top of the push rod 12. A top cover 14 is movably connected to the top of the hopper 6. Limit blocks 15 are fixedly installed on both sides of the top cover 14. Limit grooves 1501 are opened on the outer side of the limit blocks 15. The connecting plate 13 is snapped into the inside of the limit grooves 1501. The push rod 12 is driven to rise and fall by the drive box 11, thereby driving the top cover 14 to rise and open and close. Material is fed into the hopper 6 through the opening when it rises.
[0033] A motor 16 is fixedly installed at the center of the top of the top cover 14. A stirring rod 17 is fixedly installed at the output end of the motor 16. The bottom end of the stirring rod 17 extends through into the interior of the silo body 6. Two sets of stirring blades 18 are fixedly connected to the outside of the stirring rod 17. A rotating bearing is provided at the connection between the top cover 14 and the stirring rod 17. The stirring rod 17 is positioned above the screen plate 9 and does not contact its upper surface. A protective cover 19 is provided at the center of the top cover 14. The motor 16 is located inside the protective cover 19. The rotation of the stirring rod 17 drives the stirring blades 18 to rotate, which mixes and blends the aggregate stored in the silo body 6 before feeding it out. This prevents the formation of large amounts of lumps and avoids clogging the feed.
[0034] Example 2:
[0035] Based on Embodiment 1, this embodiment details the material discharge chamber 602 in Embodiment 1. The material discharge chamber 602 is threadedly connected to the lower part of the bin body 6. The screen plate 9 is snapped into the inside of the material discharge chamber 602. Multiple sets of screen holes are evenly distributed and equidistantly opened on the screen plate 9. The bottom of the material discharge chamber 602 is connected to the outlet 20 at the center position. The bottom of the outlet 20 is provided with a sealing bottom cover.
[0036] The pallet 8 is matched with the material discharge chamber 602. External material receiving tools are placed on the pallet 8.

The pallet 8 slides inside the sliding groove 21. Two sets of limiting slots 22 are symmetrically provided on both sides of the bottom of the sliding groove 21. Two sets of limiting sliders 23 are fixedly installed on both sides of the bottom of the pallet 8. The limiting sliders 23 and the limiting slots 22 slide with a clearance fit. The sliding connection makes it easy to pull out the pallet 8 to pick up the material, making the material picking work more convenient.
[0037] Working principle: During use, this device stores concrete aggregate in the silo 6. The motor 16 located at the center of the top of the top cover 14 drives the mixing rod 17 to rotate. The rotation of the mixing rod 17 drives the mixing blades 18 to rotate, which mixes and blends the aggregate stored in the silo 6 before feeding it out. This prevents the formation of large amounts of lumps and avoids material blockage. The aggregate is also more uniform in texture, which does not affect the later use effect.
[0038] A drive motor 3 is installed on the upright plate 2. The drive motor 3 drives the rotating shaft 4 to rotate. The rotating shaft 4 causes the bin 6 to swing before material is discharged. During the swinging process, the aggregate inside the bin 6 is screened by the screening plate 9. The aggregate with uniform texture falls through the screen holes. The external receiving device is placed on the set tray 8. After receiving the material, the tray 8 is pulled to slide and connect. The material is not interfered with the discharge port when it is picked up, which makes it more convenient for the staff to pick up the material.
[0039] It should be noted that the drive motor 3, drive box 11 and motor 16 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
