[0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a type of high-viscosity organic liquid, mostly existing in liquid or semi-solid petroleum form, with a black surface.

[0030] Reference Figures 1 to 6 This utility model provides a quantitative feeding device for asphalt processing: it includes a box body 1 and an observation window 3. The observation window 3 is located on the front wall of the box body 1. A scale groove is opened on the front wall of the box body 1 near the observation window 3. The upper surface of the box body 1 is connected to a feeding hopper 2, and the lower surface of the box body 1 is connected to a base 4.

The side walls of the two movable frames 11 near the base 4 are fixedly installed with baffles 12. The interior of the base 4 has a through slot 13. The two baffles 12 are slidably connected to the inner wall of the slot 13. A sealing ring is fixedly installed on the outer surface of the baffle 12. The inner wall of the slot 13 is in close contact with the sealing ring.

[0031] In order to crush the lumpy asphalt raw materials, a drive rod 14 and a transmission rod 15 are inserted through the side wall of the box body 1. A gear 16 is fixedly installed at one end of the drive rod 14 and the transmission rod 15. The gear 16 on the drive rod 14 meshes with the gear 16 on the transmission rod 15. A drive motor 17 is fixedly installed on the outer surface of the box body 1. The end of the drive rod 14 away from the gear 16 is fixedly installed at the output end of the drive motor 17. Several crushing discs 18 are fixedly installed on the outer surface of the drive rod 14 and the transmission rod 15 inside the box body 1.

[0032] By setting up a housing 1, a feeding hopper 2, an observation window 3, a base 4, a discharge pipe 5, a mounting flange 6, a mounting plate 7, a servo motor 8, a threaded rod 9, a sliding rod 10, a movable frame 11, a baffle 12, a slot 13, a drive rod 14, a transmission rod 15, a gear 16, a drive motor 17, and a crushing disc 18, the system achieves the function of accurately proportioning asphalt raw materials. The quantity of asphalt raw materials added can be clearly seen through the observation window 3 and the scale groove, thereby improving the accuracy of the quantity of asphalt raw materials added, preventing errors in the asphalt raw material proportioning, avoiding affecting the quality of the processed asphalt, and improving the yield of asphalt production.

[0033] The outer surface of the housing 1 is provided with a positioning assembly, which includes two fixing plates 19. The two fixing plates 19 are fixedly installed on the two side walls of the housing 1 respectively. A threaded rotating rod 20 is rotatably connected to the upper surface of one end of a fixing plate 19. The threaded rotating rod 20 passes through the fixing plate 19. A rotating block 21 is fixedly installed at the top of the threaded rotating rod 20. A lifting cylinder 22 is sleeved on the outer surface of the bottom end of the threaded rotating rod 20. A threaded groove is opened on the inner wall of the lifting cylinder 22. The lifting cylinder 22 is threadedly connected to the threaded rotating rod 20 through the threaded groove. An installation frame 23 is fixedly installed at the bottom end of the lifting cylinder 22. Several installation bolts 24 are threadedly connected to the upper surface of the installation frame 23. The installation bolts 24 pass through the upper surface of the installation frame 23. Three telescopic rods 25 are fixedly installed on the upper surface of the installation frame 23. The top ends of the three telescopic rods 25 are fixedly connected to the lower surface of the corresponding fixing plate 19 respectively.

[0034] By setting up a fixed plate 19, a threaded rotating rod 20, a rotating block 21, a lifting cylinder 22, a mounting frame 23, mounting bolts 24, and a telescopic rod 25, the feeding device can be conveniently and quickly positioned and installed. By setting up the mounting frame 23 and the mounting bolts 24, the feeding device and the mounting frame 23 are first placed in the installation position of the feeding device, and then the mounting frame 23 is fixed with the mounting bolts 24, thereby positioning the feeding device. At the same time, the threaded rotating rod 20 and the lifting cylinder 22 achieve the function of lifting and lowering the feeding device, making it more convenient to install the feeding device on the mixing device and improving the practicality of the feeding device.

[0035] Working principle: When installing the feeding device onto the mixing device, lift the feeding device and place it above the mixing device so that the feeding pipe 5 of the feeding device is aligned with the feeding pipe of the mixing device. Then, tighten the mounting bolt 24 so that the mounting bolt 24 passes through the mounting frame 23 and rotates into the upper surface of the mixing device, restricting the mounting frame 23 and positioning the feeding device. Then, rotate the rotating block 21. When the rotating block 21 rotates, it drives the threaded rotating rod 20 to rotate. Since the mounting frame 23 is in a fixed state, and under the action of the telescopic rod 25, the threaded rotating rod 20 extends into the interior of the lifting cylinder 22. At the same time, the box 1 is lowered through the fixing plate 19, and the telescopic rod 25 shortens. When the mounting flange 6 on the feeding pipe 5 contacts the flange on the feeding pipe of the mixing device, the mounting flange 6 is fixedly connected to the flange by bolts, completing the installation of the feeding device.

[0036] When adding asphalt raw materials to the mixing device using the feeding device, the baffle 12 is inserted into the slot 13, and the two baffles 12 are in contact with each other, causing the discharge pipe 5 to be blocked. The drive motor 17 is started. When the drive motor 17 runs, it drives the drive rod 14 to rotate. At the same time, the drive rod 14 drives the transmission rod 15 to rotate through the gear 16, so that the crushing discs 18 on the drive rod 14 and the transmission rod 15 rotate in opposite directions. Then, the asphalt raw materials are added into the box 1 through the feed hopper 2. The two sets of crushing discs 18 rotating in opposite directions crush the lumps of raw materials in the asphalt raw materials. At the same time, the amount of asphalt raw materials is observed through the observation window 3 and the scale groove. When the amount of asphalt raw materials reaches the appropriate amount, the addition of raw materials is stopped. Then, the servo motor 8 is started. When machine 8 is running, it drives the threaded rod 9 to rotate. When the threaded rod 9 rotates, it drives the two movable frames 11 to move. Under the action of the slide rod 10, the two movable frames 11 slide along the outer surface of the slide rod 10 from the middle position of the threaded rod 9 to both ends of the threaded rod 9. At the same time, it drives the two baffles 12 to slide outward through the slot 13 to the base 4. The two baffles 12 move away from each other, thereby relieving the blockage of the feed pipe 5. The asphalt raw material enters the mixing device from the inside of the box 1 through the feed pipe 5. When all the asphalt raw material inside the box 1 has entered the mixing device, the servo motor 8 is controlled to run in reverse to block the feed pipe 5. The above operation is repeated to feed different asphalt raw materials. After the feeding is completed, the asphalt can be processed by the mixing device.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
