Description

Technical Field

[0001] This utility model relates to the field of batching devices for belt-driven asphalt concrete production, and more specifically, to a batching device for belt-driven asphalt concrete production. Background Technology

[0002] Asphalt concrete, also known as asphalt concrete, is a mixture made by manually selecting mineral materials with a certain gradation, such as crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and mixing them with a certain proportion of road asphalt materials under strict control conditions. In the production of concrete, after the batching is completed, a belt conveyor device is used to transfer and transport the concrete material, which saves the workload of the workers. However, the feeding devices currently on the market still have the following shortcomings.

[0003] Currently, the belt feeding devices on the market can only feed concrete using belts, but they do not have a concrete batching structure. Therefore, concrete cannot be batched and fed continuously on the feeding device, which reduces processing efficiency and increases the workload of workers.

[0004] In existing technologies, such as authorized publication number CN220501758U, this utility model discloses a belt-type batching and feeding device for asphalt concrete production. It includes a workbench, with a mounting base installed above the workbench via a bracket. Multiple rollers are equidistantly rotatably mounted within the mounting base, and a conveyor belt is correspondingly fitted around the outside of each roller. A drive shaft is rotatably mounted on one side of the mounting base, and the drive shaft is in driving contact with the conveyor belt. This utility model, by incorporating a batching unit, can fully mix the various raw materials within the batching chamber, achieving concrete batching. After batching, the concrete is conveyed onto the conveyor belt, which then continuously and rapidly transfers and transports the concrete, improving the efficiency of concrete batching and feeding. Furthermore, an adjustment unit is added to the mounting base to facilitate flexible control of the conveyor belt tension during conveying, ensuring safe and stable concrete transport.

[0005] In the aforementioned patent, mixing and conveying are combined, and the material is directly conveyed out after mixing. However, in use, the vertical mixing mechanism used in the aforementioned patent is tall, making it inconvenient to feed materials. Moreover, the mixing mechanism is complex and costly. The mixing component and the conveying component are two independent devices, which require two drive devices for control, resulting in high overall costs. Utility Model Content

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a batching device for belt-driven asphalt concrete production. By using the same drive for the conveyor belt and the mixing components, the horizontal mixing and feeding is convenient, and the mixing and conveying use the same drive motor equipment, which reduces the overall cost.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A belt-driven batching device for asphalt concrete production includes a conveyor. A conveyor belt roller is mounted on the upper inner surface of the conveyor, and a conveyor belt is installed on the outer surface of the conveyor belt roller. A support base is fixedly connected to one upper surface of the conveyor. A mixing drum is connected to the inner surface of the support base via a bearing ring. A rotating shaft is fixedly connected to the inner surface of the mixing drum. Spiral conveying ribs are fixedly connected to the inner wall surface of the mixing drum. A first pulley is fixedly connected to the outer end surface of the conveyor belt roller, and a second pulley is fixedly connected to the outer end surface of the rotating shaft. A drive belt is installed on the inner sides of the first and second pulleys. The outer end surface of the conveyor belt roller is connected to the drive shaft of a motor. By using the same drive for the conveyor belt and the mixing assembly, horizontal mixing and feeding are convenient. The use of the same drive motor for mixing and conveying reduces overall costs.

[0009] Furthermore, flanges are fixedly connected to the end face of the drive shaft of the motor and the end face of the conveyor belt roller, and are connected to each other through the flanges.

[0010] Furthermore, a mounting platform is provided on the side of the conveyor, and the motor is fixedly connected to the upper surface of the mounting platform.

[0011] Furthermore, the first pulley is a large-sized pulley, and the second pulley is a small-sized pulley, with the diameter of the first pulley being larger than the diameter of the second pulley.

[0012] Furthermore, the lower surface of the conveyor is fixed with support legs, and six sets of support legs are distributed and fixed on the lower surface of the conveyor.

[0013] Furthermore, a mounting platform is fixedly connected to the outer surface of the support leg, and the mounting platform is fixedly disposed on one side of the outer surface of the support leg.

[0014] Furthermore, the outer surfaces of the left and right sides of the conveyor belt are tightly attached to the inner surface of the conveyor.

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) By using the same drive for the conveyor belt and the mixing component, the horizontal mixing is convenient for feeding. The mixing and conveying use the same drive motor equipment, which reduces the overall cost. Attached Figure Description

[0024] 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.

[0025] Example 1

[0026] Please see Figure 1-5A belt-driven batching device for asphalt concrete production includes a conveyor 1, a conveyor belt roller 2 on the upper inner surface of the conveyor 1, a conveyor belt 3 on the outer surface of the conveyor belt roller 2, a support base 4 fixedly connected to one side of the upper surface of the conveyor 1, a mixing drum 6 connected to the inner surface of the support base 4 via a bearing ring 5 (the bearing ring 5 supports the rotation of the mixing drum 6, facilitating rotational positioning support), a rotating shaft 7 fixedly connected to the inner surface of the mixing drum 6, spiral conveying ribs 8 fixedly connected to the inner wall surface of the mixing drum 6, a first pulley 9 fixedly connected to the outer end surface of the conveyor belt roller 2, a second pulley 10 fixedly connected to the outer end surface of the rotating shaft 7, a drive belt 11 installed on the inner side of the first pulley 9 and the second pulley 10, and a drive shaft 12 connected to the outer end surface of the conveyor belt roller 2. 12. A reversible motor is used. A reversible motor is a motor that can change its rotation direction during operation, that is, it can rotate from clockwise to counterclockwise, or from counterclockwise to clockwise. This function is used in many industrial and civil equipment because it provides more operational flexibility and control capabilities. Motor reversal means that the motor can change its rotation direction during operation. For AC motors, this can be achieved by changing the phase sequence of the power supply or by using a frequency converter to change the frequency and phase of the power supply. For DC motors, this can also be achieved by changing the current direction in the armature winding or field winding. By using the same drive for the conveyor belt and the mixing assembly, horizontal mixing and feeding are convenient. Using the same drive motor for mixing and conveying reduces overall costs.

[0027] A flange 13 is fixedly connected to the end face of the drive shaft of the motor 12 and the end face of the conveyor belt roller 2, and they are connected to each other through the flange 13.

[0028] A mounting platform 14 is provided on the side of the conveyor 1, and the motor 12 is fixedly connected to the upper surface of the mounting platform 14; this facilitates the installation and use of the motor 12.

[0029] The first pulley 9 is a large-sized pulley, and the second pulley 10 is a small-sized pulley. The diameter of the first pulley 9 is larger than the diameter of the second pulley 10. This allows the large pulley to drive the small pulley to rotate, which can drive the mixing drum 6 to rotate quickly and speed up the mixing. The conveyor drive rotates very slowly, but by using the diameter ratio, it can speed up the rotation and mixing of the mixing drum 6, making it convenient to use.

[0030] Support legs 100 are fixed to the lower surface of conveyor 1, and six sets of support legs 100 are distributed and fixed to the lower surface of conveyor 1 to support the stability of conveyor 1.

[0031] A mounting platform 14 is fixedly connected to the outer surface of the support leg 100. The mounting platform 14 is fixedly set on one side of the outer surface of the support leg 100; this facilitates the installation and use of the motor 12. The outer surfaces of the left and right sides of the conveyor belt 3 are tightly attached to the inner surface of the conveyor 1. With the two sides tightly attached to the conveyor, when the conveyor belt 3 rotates, it can transport asphalt concrete without leaking into the gaps.

[0032] In use, a support base 4 is fixedly connected to the upper surface of one side of the conveyor 1. A mixing drum 6 is connected to the inner surface of the support base 4 via a bearing ring 5. A rotating shaft 7 is fixedly connected to the inner surface of the mixing drum 6. Spiral conveying ribs 8 are fixedly connected to the inner wall surface of the mixing drum 6. A first pulley 9 is fixedly connected to the outer end surface of the conveyor belt roller 2. A second pulley 10 is fixedly connected to the outer end surface of the rotating shaft 7. A drive belt 11 is installed inside the first pulley 9 and the second pulley 10. The outer end surface of the conveyor belt roller 2 is connected to the drive shaft of the motor 12. Material is introduced through the opening on one side of the mixing drum 6. After introduction, the first pulley 9 driven by the motor 12 drives the second pulley 10 to rotate in the opposite direction. Driven by the transmission belt 11, it can drive the mixing drum 6 to rotate, and the concrete and asphalt inside can be turned over and mixed. After mixing, the motor 12 rotates in the forward direction, which can drive the mixing drum 6 to rotate in the forward direction. Through the built-in spiral conveyor 8, the internal material can be guided out during forward rotation (during reverse rotation, the material will not be discharged through the spiral conveyor 8, but will only be turned over and mixed inward). It is convenient to guide and feed material, and the horizontally distributed mixing drum 6 is easy to use.

[0033] While guiding the material, the conveyor belt 3 rotates synchronously, which can transport the discharged material. The conveying is convenient. By using the same drive for the conveyor belt and the mixing component, the horizontal mixing and feeding is convenient. The mixing and conveying use the same drive motor equipment, which reduces the overall cost.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
