Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete production technology, and in particular to a concrete feeding device for concrete production. Background Technology
[0002] Concrete is a composite material formed by bonding fine and coarse aggregates with cement and allowing it to harden over a period of time. Currently, in the concrete production process, a hopper is needed to process the concrete, and many large pieces of material such as gravel that do not meet the requirements are filtered out from the concrete.
[0003] Chinese Patent 202323667045.8 discloses a concrete feeding device for concrete production, relating to the field of concrete feeding technology. This concrete feeding device includes a silo with supports fixedly connected to both sides. A discharge block is fixedly connected to the front surface of the silo, and a motor is fixedly installed on the front surface of the discharge block. A hopper is provided on the lower surface of the silo, and two T-shaped blocks are fixedly connected to the upper surface of the hopper. The device utilizes a filter screen fixedly connected inside the silo, with an inclined design. During the feeding process, the filter screen filters out large pieces of material such as gravel that do not meet requirements from the concrete. The filtered material rolls down at an angle and is blocked by a baffle. When too much filtered material accumulates, the motor is activated, and its output shaft drives a screw to rotate. The screw, through its threaded action, moves the surface-mounted baffle forward, at which point the discharge block opens its limit position.
[0004] However, in actual use, the baffle and screw of the above-mentioned concrete feeding device are located inside the silo. This layout not only occupies the limited space of the silo, but also hinders the normal operation of the filter screen to a certain extent. Due to the interference of the baffle and screw, the filtration efficiency of the filter screen is reduced, and it cannot fully play its due filtration role, which easily causes blockage. Therefore, a concrete feeding device for concrete production is proposed to solve the above problems. Utility Model Content
[0005] (a) Purpose of the utility model

Through multiple second connecting rods, it can drive a first rotating ring to rotate on the inner cylinder. As the first rotating ring rotates, it causes the screening plate to rotate accordingly. When concrete falls onto the rotating screening plate, the concrete on the plate is dispersed by centrifugal force, allowing full utilization of the screening plate. Large, non-compliant materials such as gravel will gradually move outwards due to centrifugal force, passing through the gap between the inner cylinder and the outer ring and falling into the collection component. This fully utilizes the filtering effect of the screening plate, improving production and filtration efficiency while reducing maintenance costs. Attached Figure Description

[0031] As shown in Figures 1-4, the present invention proposes a concrete feeding device for concrete production, which includes an inner cylinder 15 and an outer ring 3 located outside it. The inner cylinder 15 has a discharge hopper 10 at the bottom edge and a second rotating ring 18 rotatably and slidably connected at the upper edge of the inner cylinder 15. The outer end face of the inner cylinder 15 is connected to the inner wall of the outer ring 3 through a first connecting rod 8 distributed in a ring array.
[0032] The inner cylinder 15 has a first rotating ring 16 at its upper edge, which is rotatably and slidably connected. The first rotating ring 16 and the second rotating ring 18 are connected by a plurality of second connecting rods 17 arranged in a ring array. The inner wall of the first rotating ring 16 is provided with a screening plate 2. The outer wall of the second rotating ring 18 is provided with a plurality of toothed blocks 11 arranged in a ring array. The outer end face of the outer ring 3 is provided with an output component. The transmission end of the output component is connected to the plurality of toothed blocks 11.
[0033] Includes a feeding hopper 7, the outer end face of which is connected to the outer wall of the outer ring 3 through multiple fixing brackets 1. The multiple fixing brackets 1 can serve to fix the feeding hopper 7.
[0034] A collection component is provided on the outer end face of the inner cylinder 15 and below the outer ring 3, so that it can collect large materials such as gravel that do not meet the requirements.
[0035] A support assembly is provided on the outer end face of the inner cylinder 15 and below the collecting assembly, so that the inner cylinder 15 can be stably supported.
[0036] In this invention, during use, concrete is added through the feeding hopper 7, and the concrete falls onto the screening plate 2. The output end of the output component then drives the second rotating ring 18 to rotate on the outer ring 3 via multiple toothed blocks 11. Through multiple second connecting rods 17, it drives the first rotating ring 16 to rotate on the inner cylinder 15. The rotation of the first rotating ring 16 causes the screening plate 2 to rotate accordingly. When the concrete falls onto the rotating screening plate 2, it is dispersed by centrifugal force, allowing full utilization of the screening plate 2. Large materials such as gravel that do not meet requirements gradually move outwards due to centrifugal force, passing through the gap between the inner cylinder 15 and the outer ring 3, and thus falling into the collection component. The concrete screened by the screening plate 2 falls into the inner cylinder 15 and finally exits through the discharge hopper 10.
[0037] In an optional embodiment, the output component includes a gear 12, a drive motor 13, and a motor support plate 14. The motor support plate 14 is located on the side of the outer ring 3, the drive motor 13 is located on the motor support plate 14, and the gear 12 is coaxially connected to the output shaft of the drive motor 13. The gear 12 meshes with a plurality of tooth blocks 11.
[0038] It should be noted that the motor support plate 14 can be used to install the drive motor 13. When the drive motor 13 is started, the drive motor 13 can drive the gear 12 to rotate. When the gear 12 rotates, it can drive the second rotating ring 18 to rotate at the upper edge of the outer ring 3 through multiple tooth blocks 11.
[0039] In an optional embodiment, the outer end faces of both the second connecting rod 17 and the first connecting rod 8 are smooth.
[0040] It should be noted that this design prevents material from falling onto the second connecting rod 17 and the first connecting rod 8 and leaving residue.
[0041] In an optional embodiment, the screening plate 2 is conical or curved, and the discharge port of the hopper 7 is located above the middle of the screening plate 2.
[0042] It should be noted that the concrete can fall onto the center of the screening plate 2 along the slope of the screening plate 2, allowing the concrete to flow and spread more smoothly.
[0043] In an optional embodiment, the collection assembly includes a placement plate 19, a collection box 4, and a handle 9. The placement plate 19 is disposed on the outer end face of the inner cylinder 15. There are two collection boxes 4, which are symmetrically distributed. The symmetrically distributed collection boxes 4 are placed on the upper end of the placement plate 19. The handle 9 is disposed on the side of the collection box 4. The inner diameter of the collection box 4 is the same as the outer diameter of the inner cylinder 15.
[0044] It should be noted that the placement plate 19 can be used to move the collection box 4; the collection box 4 can be used to collect large materials such as gravel that do not meet the requirements. When there are many unqualified gravel inside the collection box 4, it can be removed from the placement plate 19 and the unqualified gravel can be poured out, and then the placement plate 19 can be installed again.
[0045] In an optional embodiment, the collection box 4 is arranged in a semi-circular shape, with the inlet of the collection box 4 facing upwards, and a magnet plate 20 is embedded in the contact surface between the two collection boxes 4.
[0046] It should be noted that the magnetic plates 20 embedded in the contact surfaces of the two collection boxes 4 can magnetically connect the two collection boxes 4, thereby preventing the collection boxes 4 from sliding when collecting stones that do not meet the requirements.
[0047] In an optional embodiment, the support assembly includes an annular plate 5 and support rods 6. The annular plate 5 is located below the outer end face of the inner cylinder 15, and a plurality of support rods 6 are arranged in an annular array at the bottom of the annular plate 5. The plurality of support rods 6 are vertically arranged and their bottoms are all located on the same plane.
[0048] It should be noted that multiple support rods 6 can provide support for the annular plate 5 and provide stable support for the inner cylinder 15.
[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
