Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete preparation technology, specifically to a recycled aggregate concrete raw material proportioning device. Background Technology
[0002] With the booming development of the construction industry, the demand for building materials is increasing day by day. At the same time, the concepts of environmental protection and sustainable development are becoming more and more popular. Recycled aggregate concrete, as a green and environmentally friendly building material, is made by using recycled aggregates obtained from construction waste such as waste concrete through crushing, screening and other processes. It partially or completely replaces natural aggregates. It not only effectively solves the environmental pollution and land occupation problems caused by the accumulation of construction waste, but also reduces the mining of natural aggregates, which meets the requirements of resource recycling and sustainable development.
[0003] In the production process of recycled aggregate concrete, the raw material ratio is an important part of the processing. A reasonable raw material ratio can ensure that the concrete has good workability, mechanical properties and durability, which directly affects the quality and safety of construction projects.
[0004] In existing technologies, the raw material proportioning devices for recycled aggregate concrete lack effective means of controlling the amount of raw material fed in. This can lead to situations where too much or too little raw material passes through the feeding device each time. When too much raw material is fed in, the connecting pipes between the feeding device and subsequent equipment, as well as the storage tanks, are prone to blockage. This can cause production interruptions, affect production efficiency, increase equipment maintenance costs and downtime, and may also cause segregation and agglomeration due to prolonged accumulation of raw material in pipes and tanks, further affecting the quality stability of recycled aggregate concrete.
[0005] In view of the above, this application is hereby submitted. Utility Model Content
[0006] The purpose of this invention is to provide a recycled aggregate concrete raw material proportioning device to solve the problems mentioned in the background art.
[0007] To solve the above-mentioned technical problems, this utility model provides a recycled aggregate concrete raw material proportioning device, including a storage tank, a control console installed at the top of the storage tank, a connecting pipe installed inside the control console, the bottom end of the connecting pipe connected to the top of the storage tank, a control box fixedly connected to the top of the connecting pipe, a feeding box fixedly connected inside the control box, an infeed cylinder fixedly connected to the top of the feeding box, a motor installed on one side of the inner wall of the storage tank, a first bevel gear connected to the output end of the motor, a spiral blade rotatably connected to the inner wall of the infeed cylinder, a second bevel gear fixedly connected to the end of the spiral blade near the motor, and the first bevel gear and the second bevel gear are meshed.

When the telescopic rod pushes the push plate to move, the first blade and the second blade will rotate according to the displacement of the push plate.
[0010] Furthermore, brackets are installed on both sides of the bottom of the storage tank, and the top of the brackets is fixedly connected to the storage tank.
[0011] Furthermore, the side of the motor furthest from the output end is fixedly connected to the inner wall of the control panel, and the first bevel gear will rotate synchronously after the motor starts.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0025] 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.
[0026] Please see Figures 1-7This utility model provides a technical solution: a recycled aggregate concrete raw material proportioning device, including a storage tank 1, located at the bottom of the device, serving as the final storage container for the raw materials. The storage tank 1 stores the proportioned recycled aggregate concrete raw materials, providing a stable supply of raw materials for subsequent production stages. Its large capacity design can meet the raw material storage needs of a certain scale of production, improving production efficiency. A control console 2 is installed at the top of the storage tank 1, and a connecting pipe 3 is installed inside the control console 2. The bottom end of the connecting pipe 3 is connected to the top of the storage tank 1, and a control box 4 is fixedly connected to the top of the connecting pipe 3. The connecting pipe 3 connects the control box 4 and the storage tank 1, serving as the channel for transporting raw materials from the control box 4 to the storage tank 1, ensuring smooth material transport and preventing blockages or leaks during transport, thus improving the efficiency and stability of material transport. A discharge box 10 is fixedly connected inside the control box 4, and an infeed cylinder 5 is fixedly connected to the top of the discharge box 10. The infeed cylinder 5 serves as the raw material... The inlet of the device guides the raw material into the feeding box 10. The inner wall of the feeding cylinder 5 is smooth, reducing the friction of the raw material during entry and improving the flow efficiency. A motor 6 is installed on one side of the inner wall of the storage tank 1, serving as the drive source. The output end of the motor 6 is connected to a first bevel gear 7. A spiral blade 9 is rotatably connected to the inner wall of the feeding cylinder 5. The shape of the spiral blade 9 can effectively push the raw material forward, improving the conveying efficiency. A second bevel gear 8 is fixedly connected to the end of the spiral blade 9 near the motor 6. The first bevel gear 7 and the second bevel gear 8 are meshed. After the motor 6 starts, it drives the first bevel gear 7 to rotate, which in turn drives the spiral blade 9 to rotate, realizing the conveying of the raw material. The first bevel gear 7 and the second bevel gear 8 change the direction of power transmission of the motor 6, transmitting it to the spiral blade 9, so that the spiral blade 9 can rotate normally in the feeding cylinder 5. The meshing transmission method of the first bevel gear 7 and the second bevel gear 8 can withstand a large torque, ensuring the reliability of power transmission.
[0027] See Figure 3 , Figure 5 , Figure 6 , Figure 7A switch assembly is installed on the inner wall of the feeding box 10. The feeding box 10 is connected to both the feeding cylinder 5 and the connecting pipe 3, serving as a raw material transfer and feeding control mechanism. The switch assembly includes a telescopic rod 11 installed on the inner wall of the feeding box 10. The telescopic end of the telescopic rod 11 is connected to a push plate 12. The telescopic rod 11 serves as the power source for the switch assembly, and by starting it, it pushes the push plate 12 to move. The inner walls of the push plate 12 are respectively connected to a first blade 13 and a second blade 14. The first blade 13 and the second blade 14 are rotatably connected. The push plate 12 can transmit the force of the telescopic rod 11 to the first blade 13 and the second blade 14, ensuring the rotational synchronization and stability of the first blade 13 and the second blade 14. The first blade 13 and the second blade 14 change the opening size at the bottom of the feeding box 10 through rotational movement, controlling the falling speed and amount of raw materials. When the push plate 12 pushes them to rotate, the included angle between the first blade 13 and the second blade 14 changes, thereby adjusting the opening and closing degree of the bottom of the feeding box 10.
[0028] See Figure 1 Both sides of the bottom of the storage tank 1 are equipped with brackets 15. The top of the brackets 15 is fixedly connected to the storage tank 1. The brackets 15 provide stable support for the storage tank 1 and evenly transfer the weight of the storage tank 1 and the raw materials inside to the ground or other supporting surfaces, so as to avoid affecting the normal storage and use of the raw materials due to tilting or shaking.
[0029] See Figure 2 A control panel is installed on one outer wall of the control box 4, and buttons and a display screen are installed on one outer wall of the control panel. The control box 4 serves as the interface for operators to interact with internal components, reducing the time that workers have to contact mechanical components and improving safety in the production process.
[0030] Working principle: Raw materials enter the feed cylinder 5 through the feed port at the top of the feed cylinder 5. The output end of the motor 6 drives the first bevel gear 7 to rotate. Since the first bevel gear 7 is meshed with the second bevel gear 8, the second bevel gear 8 rotates synchronously, driving the spiral blade 9 to rotate on the inner wall of the feed cylinder 5. The spiral structure of the spiral blade 9 gradually conveys the raw materials downward to the feed box 10 during the rotation. Then, the telescopic rod 11 controls the extension and retraction to push the push plate 12 to move. Because the inner walls of the push plate 12 are respectively connected to the first blade 13 and the second blade 14, the first blade 13 and the second blade 14 are rotatably connected. The end of the first blade 13 away from the telescopic rod 11 is rotatably connected to the inner wall of the feed box 10. The displacement of the push plate 12 pushes the first blade 13 and the second blade 14 to rotate, changing the included angle between them, thereby adjusting the size of the opening at the bottom of the feed box 10, and realizing the adjustment of the opening.
