Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and in particular to a weighing and feeding device for asphalt concrete raw materials. Background Technology

[0002] Asphalt concrete is a type of concrete made by mixing asphalt with aggregates, fillers, and other materials, primarily used in road construction. Asphalt itself is a black, gelatinous substance, mainly composed of petroleum residue, with a content exceeding 90%. Although asphalt and asphalt concrete differ significantly in composition and application, asphalt concrete still falls under the category of concrete.

[0003] Asphalt concrete is a mixture made by 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 through a mixing mechanism. This mixture can meet the requirements of production applications.

[0004] However, existing asphalt concrete has the following defects during processing:

[0005] Currently, when mixing asphalt concrete, it is necessary to weigh the three main raw materials—gravel, mineral powder, and asphalt—separately according to a preset raw material ratio. Then, the weighed raw materials are transported to the mixing unit, and the three main raw materials are added to the mixing unit separately through a feeding mechanism. This makes the operation cumbersome and makes it impossible to feed the raw materials into the mixing equipment simultaneously or in sequence according to the needs. Utility Model Content

[0006] In view of the existing technology, when mixing asphalt concrete, it is necessary to weigh the three main raw materials, namely gravel, mineral powder and asphalt, according to the preset raw material ratio. Then, the weighed raw materials are transported to the mixing mechanism and then fed into the mixing mechanism by the feeding mechanism. This makes the operation cumbersome and makes it impossible to feed the raw materials into the mixing equipment synchronously or in sequence as needed. The present invention provides an asphalt concrete raw material weighing and feeding device.

[0007] The technical solution adopted by this utility model is: an asphalt concrete raw material weighing and feeding device, including a weighing base, a first support frame, a mixing mechanism, and a second support frame.

[0015] 1. This utility model, through a feeding mechanism and a weighing base, allows for the precise weighing of raw materials before they are added to the mixing mechanism. It also enables the simultaneous or sequential feeding of various raw materials into the mixing equipment, thereby ensuring accurate material proportions and timely feeding, and guaranteeing the stable operation of the mixing process.

[0025] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0026] In order to solve the problems existing in the background technology, this application proposes the following technical solution: an asphalt concrete raw material weighing and feeding device.

[0027] The specific technical solution includes a weighing base 1, a first support frame 2, a stirring mechanism 3, and a second support frame 4. The first support frame 2 is fixedly installed on the upper side of the weighing base 1. The stirring mechanism 3 is located in the middle of the first support frame 2. The second support frame 4 is fixedly installed on the upper side of the first support frame 2. Three feeding mechanisms 5 are arranged between the second support frame 4 and the weighing base 1. The feeding mechanism 5 includes a lifting mechanism 6, a moving mechanism 7, a discharge hopper 11, a linear guide frame 8, and an L-shaped guide frame 9. The moving mechanism 7 is located on one side of the second support frame 4, and the lifting mechanism 6 is located below the moving mechanism 7. The discharge hopper 11 is connected to the output end of the lifting mechanism 6. There are two linear guide frames 8 and two L-shaped guide frames 9. Two linear guide frames 8 are fixedly installed between the second support frame 4 and the weighing base 1. Two L-shaped guide frames 9 are fixedly installed on one side of the two linear guide frames 8 respectively. Guide grooves 10 are opened on one side of the two linear guide frames 8 and the two L-shaped guide frames 9. Guide slide rods 12 are fixedly installed on both sides of the discharge hopper 11. The guide slide rods 12 are slidably arranged in the guide grooves 10. A closed slot 22 is opened between the two sides of the lower end of the discharge hopper 11. Two closed insert plates 23 are slidably installed in the closed slot 22. Electric telescopic rods 24 are fixedly installed on both sides of the lower end of the discharge hopper 11. The output end of the electric telescopic rod 24 is fixedly connected to the closed insert plate 23. The stirring mechanism 3 is an existing mechanism, so it will not be described in detail.

[0028] Reference Figure 2 and Figure 3As shown, the moving mechanism 7 includes a threaded rod 19, a threaded slider 20, and a forward / reverse motor 21. A sliding groove 18 is provided on the lower side of one side of the second support frame 4. The threaded rod 19 is rotatably mounted in the sliding groove 18. The forward / reverse motor 21 is fixedly mounted on one side of the second support frame 4, and its output end is fixedly connected to one end of the threaded rod 19. The threaded slider 20 is threadedly mounted around the threaded rod 19. The lifting mechanism 6 includes a wire rope 14, a sliding bracket 15, a take-up roller 16, and a reduction motor 17. The sliding bracket 15 is fixedly mounted below the threaded slider 20, and the take-up roller 16 is rotatably mounted between the sliding brackets 15. The reduction motor 17 is fixedly mounted on one side of the sliding bracket 15, and its output end is connected to the take-up roller 16. One end of the wire rope 14 is fixedly connected to the lifting mechanism 6 and the wire rope 14 is wound around the take-up roller 16. Two lifting lugs 13 are fixedly installed on the upper side of the discharge hopper 11. One end of the wire rope 14 is connected to the two lifting lugs 13 respectively. By starting the forward and reverse motor 21, the threaded rod 19 is driven to rotate, which drives the threaded slider 20 to move. The movement of the threaded slider 20 can drive the lifting mechanism 6 and the discharge hopper 11 to move. By starting the reduction motor 17, the take-up roller 16 is driven to rotate, which allows the take-up roller 16 to loosen or wind up the wire rope 14, thereby driving the discharge hopper 11 to move up and down. When the discharge hopper 11 is raised, when it reaches the upper end, the upper side of the discharge hopper 11 will fit against the sliding bracket 15, thereby ensuring the stability of the discharge hopper 11.

[0029] Reference Figure 1 and Figure 5 As shown, the weighing base 1 has three mounting slots 25 on its upper side. A weight sensor 26 is fixedly installed in the mounting slot 25. A guide plate 27 is provided on the upper side of the weight sensor 26. The guide plate 27 is located in the mounting slot 25, and a support plate 28 is fixedly installed on the upper side of the guide plate 27. The weight sensor 26 can be connected to an external display screen so that the staff can view the data.

[0030] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0031] In use, the lifting mechanism 6 is activated to place the hopper 11 onto the support plate 28 on the weighing base 1. Before weighing, the weight sensor 26 is zeroed and calibrated. After calibration, raw materials are added to the hopper 11, enabling the weight sensor 26 to weigh the added materials. After weighing, the lifting mechanism 6 is used again to move the hopper 11 upwards. When the guide rods 12 on both sides of the hopper 11 align with the L-shaped guide frame 9, the moving mechanism 7 is activated, allowing it to move the lifting mechanism 6 and the hopper 11. The feeding hopper 11 moves with the moving mechanism 7 to the feeding port on the upper side of the mixing mechanism 3. Then, the lifting mechanism 6 is activated again to drive the feeding hopper 11 to descend, so that the discharge port on the lower side of the feeding hopper 11 is inserted into the feeding port. Then, the electric telescopic rod 24 is activated to drive the sealing plate 23 to move outward, so that the discharge port of the feeding hopper 11 is opened. Then, the raw materials enter the mixing mechanism 3 through the discharge port and the feeding port. Through the three feeding mechanisms and the weighing mechanism, various raw materials can be fed into the mixing equipment synchronously or sequentially, ensuring accurate raw material ratio and timely feeding, and ensuring the stable operation of the mixing process.
