Description

Technical Field

[0001] This utility model relates to the field of concrete construction equipment technology, and in particular to a concrete feeding device. Background Technology

[0002] Concrete pouring is a crucial part of building construction. As a key piece of equipment in concrete pouring, the performance of the concrete delivery device directly affects the quality and efficiency of the concrete pouring process.

[0003] Chinese Patent 202323594620.6 discloses a concrete feeding device for concrete production, including a fixed outer shell. A base is connected to the bottom of the fixed outer shell. A partition and a feeding hopper are fixedly connected to the inner wall of the fixed outer shell. A bottom plate is connected to the bottom of the feeding hopper. A bearing is connected to the middle of the bottom plate. A mixing component is connected to the upper end of the bearing. An opening is formed at the upper end of the bottom plate, and a filter plate is connected to the inner wall of the opening. A rotary motor is installed at the upper end of the base. A rotating shaft is connected to the output end of the rotary motor and is connected to the mixing component. This invention uses a rotary motor to drive the mixing component. The rotation of the mixing component facilitates the mixing of concrete inside the feeding hopper, preventing concrete from sticking to the inner surface of the feeding hopper. Residual concrete, after drying, is difficult to remove and affects subsequent use. Furthermore, the use of a filter plate facilitates secondary mixing of unevenly mixed or large-volume concrete, improving the concrete mixing effect.

[0004] However, when the aforementioned feeding device is in use, after a certain period of use, the filter screen inside the feeding hopper can filter out some large particles of impurities such as oversized aggregates and agglomerated materials, which remain in the feeding hopper. As the continuous operation time increases, these large particles of impurities trapped by the filter screen will continue to accumulate. When the accumulation reaches a certain level, it needs to be cleaned. However, cleaning requires stopping the entire machine, and the cleaning space is limited, which makes it inconvenient for workers to clean and affects work efficiency. Therefore, a concrete feeding device is proposed to solve the above problems. Utility Model Content

For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1-5As shown, the present invention proposes a concrete feeding device, including an outer bucket 12 and an inner bucket 2 located inside the outer bucket 12. The bottom of the outer bucket 12 is connected to the bottom plate 13 through a plurality of second support rods 14. A discharge hole is penetrating one side of the bottom of the outer bucket 12. A groove adapted to the discharge hole is penetrating the bottom of the inner bucket 2. A filter screen 27 is installed in the groove. The filter screen 27 and the inner bottom wall of the inner bucket 2 are located on the same plane. An internal hollow column 6 is coaxially connected to the inner bottom wall of the inner bucket 2.

[0033] It also includes a rotating rod 5 located inside the hollow column 6. A drive assembly is installed at the bottom of the outer barrel 12. One end of the rotating rod 5 passes through the outer barrel 12 through a bearing and is connected to the drive assembly. The other end of the rotating rod 5 is connected to the mounting block 4 through a limiting assembly. Stirring components are installed on both sides of the outer end face of the mounting block 4.

[0034] The outer end face of the outer tub 12 is connected to both sides of the outer end face and the upper edge of the inner tub 2 by a connecting component;

[0035] A discharge assembly is installed at the bottom of the discharge hole and on the upper surface of the base plate 13.

[0036] In this utility model, when concrete falls into the inner barrel 2, the drive assembly is activated, which drives the mixing component to rotate through the rotating rod 5 and the mounting block 4. When the mixing component rotates, it can drive the concrete inside the inner barrel 2 to be mixed, which is convenient for secondary mixing of concrete that is not mixed evenly or has a large volume. And through the filter screen 27, it can allow the concrete to fall through the discharge hole onto the discharge assembly for conveying.

[0037] When it is necessary to clean the concrete inside the inner bucket 2 inside the outer bucket 12, first remove the mounting block 4 from the rotating rod 5 using the limiting component, and then remove the limiting effect on the inner bucket 2 and the outer bucket 12 using the connecting components on both sides. This allows the inner bucket 2 to be removed from inside the outer bucket 12 for cleaning and replacement with a clean inner bucket 2. Then, install the inner bucket 2 inside the outer bucket 12 using the connecting components on both sides, aligning the filter screen 27 with the discharge hole. Finally, install the mounting block 4 using the limiting component, and the machine can be put back into operation.

[0038] In an optional embodiment, the drive assembly includes a first gear 23, a drive motor 24, a second gear 25, and a motor mounting bracket 26. The first gear 23 is coaxially connected to the bottom of the rotating rod 5. The motor mounting bracket 26 is installed on the bottom of the outer barrel 12. The drive motor 24 is installed on the motor mounting bracket 26. The output end of the drive motor 24 is coaxially connected to the second gear 25 through a coupling. The first gear 23 and the second gear 25 mesh with each other. The stirring component includes a rotating plate 7 and a stirring shaft 3. The two ends of the mounting block 4 are respectively connected to the rotating plate 7. The stirring shaft 3 is installed on the bottom of the rotating plate 7.

[0039] It should be noted that the motor mounting bracket 26 can be used to mount the drive motor 24. When the drive motor 24 is started, it can drive the second gear 25 to rotate. When the second gear 25 rotates, it can drive the first gear 23 to rotate, thereby driving the mounting block 4 to rotate through the rotating rod 5. When the mounting block 4 rotates, the mixing component connected to it can be driven to rotate through the rotating plates 7 located on both sides of it, thereby stirring the concrete inside the inner bucket 2.

[0040] In an optional embodiment, a gear guard plate 22 is also included, which is located at the bottom of the outer barrel 12 and outside the first gear 23.

[0041] It should be noted that the gear guard plate 22 can prevent concrete from falling from the discharge hole and coming into contact with the first gear 23, thus providing a certain degree of protection for the first gear 23.

[0042] In an optional embodiment, the limiting assembly includes a limiting block 18, a first threaded rod 19, and a first nut 15. The first threaded rod 19 is coaxially connected to the upper end of the rotating rod 5. There are two limiting blocks 18 arranged symmetrically. The symmetrically arranged limiting blocks 18 are installed on the upper end of the rotating rod 5. An opening 16 is passed through the middle of the mounting block 4. Limiting slots 17 that are adapted to the limiting blocks 18 are passed through the mounting block 4 on both sides of the opening 16. The mounting block 4 is located at the upper end of the rotating rod 5. The first threaded rod 19 is coaxially connected to the first nut 15 through the opening 16 on the mounting block 4. The symmetrically distributed limiting blocks 18 pass through the mounting block 4 through the limiting slots 17 on both sides. The outer diameter of the rotating rod 5 is smaller than the inner diameter of the internal hollow column 6.

[0043] It should be noted that when the mounting block 4 needs to be removed, firstly, the first nut 15 is rotated to remove it from the first threaded rod 19, and then the mounting block 4 is removed from the first threaded rod 19. When the mounting block 4 needs to be installed on the rotating rod 5, the mounting block 4 is installed on the rotating rod 5. At this time, the first threaded rod 19 can pass through the mounting block 4 through the opening 16, and the limiting block 18 can pass through the mounting block 4 through the limiting slot 17. Then, the first nut 15 is rotated in the opposite direction to connect with the first threaded rod 19, so that the mounting block 4 can be installed on the rotating rod 5.

[0044] In an optional embodiment, the connecting assembly includes a connecting plate 1, a second threaded rod 20, a second nut 21, and a connecting block 9. Both ends of the outer end face of the outer barrel 12 are connected to the connecting block 9, and both ends of the upper edge of the inner barrel 2 are connected to the connecting plate 1. The second threaded rod 20 is installed on the upper end of the connecting block 9. The two connecting plates 1 on both sides pass through the second threaded rod 20 on the upper end of the two connecting blocks 9, and the second nut 21 is threadedly connected to the second threaded rod 20.

[0045] It should be noted that when the inner tub 2 needs to be removed from the outer tub 12, the inner tub 2 and the outer tub 12 are removed by rotating the second nuts 21 on both sides. Then, the inner tub 2 is taken out from the inside of the outer tub 12 and the clean inner tub 2 is installed into the inside of the outer tub 12. The connecting plates 1 on both sides pass through the second threaded rods 20 on the connecting blocks 9 on both sides. The second nuts 21 are rotated in the opposite direction to make them threadedly fixed with the second threaded rods 20 and the second nuts 21, thereby realizing the disassembly and assembly of the inner tub 2.

[0046] When the inner tub 2 is installed inside the outer tub 12, the filter screen 27 needs to be located above the discharge hole.

[0047] In an optional embodiment, the discharge assembly includes a discharge ramp 10 and a first support rod 11. The upper end face of the base plate 13 is connected to the discharge ramp 10 through a plurality of first support rods 11. The discharge ramp 10 is inclined and the upper inclined surface is smooth.

[0048] It should be noted that multiple first support rods 11 can provide support for the discharge inclined plate 10; when concrete falls from inside the discharge hole, it will fall onto the inclined surface of the discharge inclined plate 10, and the concrete will slide down the inclined surface of the discharge inclined plate 10.

[0049] In an optional embodiment, handles 8 are installed on both sides of the upper edge of the inner tub 2.

[0050] It should be noted that the handles 8 on both sides make it easy for staff to remove the inner bucket 2 from the inside of the outer bucket 12.

[0051] 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.
