Description

Technical Field

[0001] This invention relates to the field of building material processing equipment technology, and in particular to a rapid batching device for recycled concrete aggregate. Background Technology

[0002] Recycled concrete aggregate refers to aggregate formed from waste concrete generated during building demolition (such as broken walls, floor slabs, beams, and columns) after crushing, washing, screening, and removal of impurities (such as reinforcing bars and sawdust). Based on particle size, it can be divided into recycled coarse aggregate and recycled fine aggregate, and is a core product of construction waste resource utilization. Its significance is profound: Firstly, my country generates over 2 billion tons of construction waste annually, with waste concrete accounting for more than half. The production of recycled aggregate can significantly absorb this waste, reducing land occupation due to stockpiling and pollution from dust and leachate caused by open-air storage. Secondly, traditional concrete production relies on natural sand and gravel aggregates, and over-exploitation has led to ecological problems such as mountain destruction, river siltation, and reduced biodiversity. Recycled aggregate can replace 30% to 100% of natural aggregates, reducing dependence on natural resources and simultaneously reducing energy consumption and carbon emissions in sand and gravel mining and transportation. Recycled concrete aggregate batching refers to the technical process of mixing recycled aggregates with natural aggregates, cement, mineral admixtures, additives, water, etc., in a specific proportion according to the concrete performance requirements of a specific project. The core is to optimize the proportion of each component through mix design. With the increasing awareness of environmental protection and the higher requirements for resource recycling rate, the application of recycled concrete aggregates is becoming more and more widespread. At present, in the building materials processing industry, a variety of automated or semi-automated mechanical equipment has been developed for the batching of recycled aggregates. These devices usually separate, screen and transport aggregates to designated locations by physical means, thereby meeting the needs of subsequent production processes and enabling the performance of recycled concrete to meet the requirements of different scenarios from roadbed subbase to high-rise building structures.

[0003] According to the public announcement (CN118925588A), a device for rapid batching of recycled concrete aggregate and its usage method are disclosed. This technology includes a hopper with a feeding mechanism below it. Movable plates are placed on two symmetrical sides inside the hopper, and second grooves are formed on each of the two symmetrical sides. A slider is installed inside the second groove, with one end of the slider mounted on the side of the movable plate and the other end of the movable plate mounted on a first mounting shaft. A circular plate is movably mounted on the side of the hopper, and a second mounting shaft is installed along the side edge of the circular plate. A second connecting rod is movably sleeved between the second mounting shaft and the first mounting shaft. By placing the two movable plates inside the hopper, the material discharge space at the hopper outlet is prevented from being reduced, thus increasing the material discharge speed of the hopper.

[0004] Although the above technical solution can avoid reducing the material discharge space at the hopper outlet by placing two movable plates inside the hopper, thus increasing the material discharge speed, the hopper outlet is relatively narrow. The movable plates further encroach on the outlet space. At the same time, the lack of unblocking devices can easily cause material blockage, resulting in low actual work efficiency and difficulty in adapting to the trend of high-speed operation in modern industry. Furthermore, due to the limited movement trajectory of the movable plates themselves, local dead zones can easily accumulate.

[0005] To address the aforementioned issues, this application proposes a rapid batching device for recycled concrete aggregates. Summary of the Invention

[0037] The following is in conjunction with the appendix Figure 1 - Appendix Figure 6 This application will be described in further detail below.

[0038] Example: A rapid batching device for recycled concrete aggregate, referring to... Figure 1 , Figure 3 and Figure 6 It includes a material bucket 1, a bucket lid 2 fixedly connected to the upper surface of the material bucket 1, and a discharge port 3 provided at the lower end of the material bucket 1.

[0039] The mixing tank 1 is equipped with a dredging component, which includes a first bevel gear 4, a rotating shaft 5, a telescopic shaft 6 and a dredging guide rod 7.

[0040] The telescopic shaft 6 has symmetrically distributed grooves 9 inside, and the rotating shaft 5 has symmetrically distributed sliders 10 on its side surface. The outer surface of the sliders 10 is slidably connected to the grooves 9.

[0041] Reference Figure 2 , Figure 3 and Figure 5The upper surface of the bucket lid 2 is provided with a drive assembly, which includes a motor 11, a rotating rod 12, a second bevel gear 13, and a third bevel gear 14. The upper surface of the bucket lid 2 is fixedly connected to the motor 11, and the output end of the motor 11 is fixedly connected to the rotating rod 12. The side surface of the rotating rod 12 is fixedly connected to both the second bevel gear 13 and the third bevel gear 14. There are two third bevel gears 14, which are symmetrically distributed. The side surface of the second bevel gear 13 meshes with the first bevel gear 4. By setting up the drive assembly, the motor 11 drives the second bevel gear 13 to rotate, the second bevel gear 13 drives the first bevel gear 4, the first bevel gear 4 drives the rotating shaft 5, and the rotating shaft 5 drives... Telescopic shaft 6 drives unblocking guide rod 7, which in turn drives spiral crusher head 8 to rotate, thereby cutting, crushing and unblocking the aggregate accumulated at discharge port 3. Two symmetrically distributed transmission components are installed on the barrel cover 2. The transmission components include a fourth bevel gear 15, a vertical rod 16 and a fifth bevel gear 17. The side surface of the third bevel gear 14 meshes with the fourth bevel gear 15, the lower surface of the fourth bevel gear 15 is fixedly connected to the vertical rod 16, the lower surface of the vertical rod 16 is fixedly connected to the fifth bevel gear 17, and the side surface of the vertical rod 16 is rotatably connected to the barrel cover 2. By setting up the transmission components, it is easy to drive the spiral crusher head 8 to rotate and lift synchronously.

[0042] Reference Figure 2 and Figure 3 The mixing tank 1 is equipped with two symmetrically distributed reciprocating components. The reciprocating components include a crossbar 18, a sixth bevel gear 19, an eccentric rod 20, and a push-pull rod 21. The side surface of the fifth bevel gear 17 is meshed with the sixth bevel gear 19. The side surface of the crossbar 18 is fixedly connected to the sixth bevel gear 19. One end of the crossbar 18 is rotatably connected to the mixing tank 1. The end of the crossbar 18 away from the mixing tank 1 is fixedly connected to the eccentric rod 20. The end of the eccentric rod 20 away from the crossbar 18 is rotatably connected to the push-pull rod 21. The lower end of the push-pull rod 21 is hinged to the telescopic shaft 6. By setting up the reciprocating components, the transmission components drive the sixth bevel gear 19 to rotate. The sixth bevel gear 19 drives the crossbar 18, and the crossbar 18 drives the eccentric rod 20. This causes the push-pull rod 21 to continuously push and pull the telescopic shaft 6 to make vertical reciprocating motion, thereby driving the spiral crusher head 8 to extend and retract inside the discharge port 3, improving the unblocking effect.

[0043] Reference Figure 4 The side surface of the telescopic shaft 6 is fixedly connected with a fishbone rod 22. There are multiple fishbone rods 22 arranged in a circular array. By setting multiple fishbone rods 22, the telescopic shaft 6 can stir the various aggregates inside the mixing tank 1 during rotation, and can also move up and down with the telescopic shaft 6, thereby improving the uniformity of aggregate mixing.

[0044] Reference Figure 1 and Figure 2Multiple conveying pipes 23 arranged in a circular array are fixedly connected to the side surface of the batching hopper 1. The lower ends of the conveying pipes 23 are connected to the interior of the batching hopper 1. By arranging multiple conveying pipes 23 along the side surface of the batching hopper 1, it is convenient to process various different aggregates. A transport assembly is arranged below the batching hopper 1. The transport assembly includes a housing 24, a second motor 25, and a conveyor belt 26. The outer surface of the housing 24 is fixedly connected to the second motor 25, and the output end of the second motor 25 is connected to the conveyor belt 26 for transmission. By arranging the transport assembly below the batching hopper 1, the mixed material that has been batched in the batching hopper 1 can be quickly transported to the next processing step, improving production efficiency.

[0045] The implementation principle of this application embodiment is as follows: In use, different types of aggregates are injected into the batching bucket 1 through the conveying pipe 23. The starting motor 11 drives the rotating rod 12 to rotate. The second bevel gear 13 on the rotating rod 12 drives the first bevel gear 4 to rotate. The first bevel gear 4 drives the rotating shaft 5. The rotating shaft 5 drives the telescopic shaft 6. The telescopic shaft 6 drives the spiral crushing head 8 at the lower end of the unblocking guide rod 7 to rotate, thereby rotating and cutting the aggregate at the discharge port 3, preventing the accumulation of large pieces of aggregate and increasing the discharge speed. In addition, the rotating rod 12 can also drive two third bevel gears 14 to rotate. The third bevel gear 14 drives the fourth bevel gear 15. The fourth bevel gear 15 drives the fifth bevel gear 17 under the upright rod 16. The rotation of the No. 5 bevel gear 17 drives the No. 6 bevel gear 19, which in turn drives the crossbar 18 to rotate. The crossbar 18 then drives the eccentric rod 20 to rotate around its axis. As the eccentric rod 20 rotates, it continuously pushes and pulls the push-pull rod 21, causing the telescopic shaft 6 to move up and down vertically. This causes the unblocking guide rod 7 and the spiral crusher head 8 to extend and retract while rotating, thus unblocking the flow. Furthermore, the pushing of the aggregate at the discharge port increases the discharge speed, achieving a simultaneous pushing and crushing effect. This not only optimizes the unblocking process but also improves the equipment's durability. Moreover, the crushed aggregate is discharged at a faster speed, further increasing the overall discharge rate.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
