[0002] Asphalt is a common petroleum product, a black, sticky organic substance commonly used in road construction, roof waterproofing, and anti-corrosion coatings. Asphalt processing is the process of transforming raw petroleum extracts into final products that can be used for various applications. The batching device is a key link in the asphalt processing process. During processing, workers need to use the batching device to select different materials and mix them in different proportions before they can be used.

[0003] A search revealed that Chinese Patent Publication No. CN222446134U discloses a batching device for asphalt processing. The device includes a feed inlet that can effectively proportion the raw materials before feeding them into a tank, and then a mixing device for mixing, which facilitates subsequent use. It also has a second observation window to facilitate observation of the mixing process in the tank and to facilitate timely discharge of the mixed raw materials. The casters also facilitate the movement of the equipment.

[0004] In actual use, when mixing materials, all raw materials enter the tank through the same feeding device. However, in the asphalt processing, materials of different properties are used, such as modifiers and additives. Some of these materials are liquids. Directly feeding them into the feeding device along with other materials will cause some of the materials to adhere to the inner wall of the feeding device, which will affect the accuracy of the batching. Therefore, a batching device for asphalt processing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a batching device for asphalt processing, which aims to improve the problem in the prior art where, when both modifiers and additives are batched using the same feeding device, some materials are wetted by liquid materials and adhere to the inner wall of the feeding device.

[0032] 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.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a batching device for asphalt processing, comprising a tank body 1. Two feed hoppers 2 are fixedly connected to the outer wall surface of the tank body 1, located on the upper left and right sides of the outer wall of the tank body 1 respectively. These hoppers can be used for feeding viscous materials and fixed materials, respectively. Viscous materials such as asphalt, after weighing and batching, enter the tank body 1 through the feed hopper 2 on the left side, while fixed materials such as mineral aggregates and fillers are added into the tank body 1 through the feed hopper 2 on the right side, improving feeding efficiency and reducing the adhesion of viscous materials to fixed materials. Modifiers, additives, and auxiliary materials are added into the tank body 1 through a configuration structure located at the top of the tank body 1. A feed inlet 3 is provided on the left side of the upper surface of tank 1. An agitator is provided at the bottom of tank 1. A discharge pipe is installed at the lower right side of tank 1. The mixed material inside tank 1 can be discharged through the discharge pipe. A valve can be installed on the outside of the discharge pipe for opening and closing control. The above structures are all existing technologies in the field and will not be described in detail here. A crossbar 6 is fixedly connected inside the feed inlet 3. A weighing device 7 is fixedly connected to the front side of the upper surface of tank 1. The left and right sides of the weighing device 7 are inclined. The weighing device 7 can weigh objects placed on it. At the same time, a display is fixedly connected to the upper surface of tank 1 to display the data weighed by the weighing device 7, which is convenient for staff to view the data directly.

[0034] Reference Figures 3-5 A cylinder 8 is provided above the tank body 1. A distance is left between the bottom surface of the cylinder 8 and the upper surface of the tank body 1 to avoid obstructing the passage of the weighing device 7. A rotating unit 9 is provided on the outside of the cylinder 8. The rotating unit 9 includes a motor 91. The motor 91 is fixedly connected to the upper surface of the tank body 1. A circular plate 92 is fixedly connected to the top output end of the motor 91. A connecting frame 93 is fixedly connected to the outer surface of the circular plate 92. The end of the connecting frame 93 away from the circular plate 92 is fixedly connected to the outer wall of the cylinder 8. When the motor 91 starts, it can drive the connecting frame 93 to rotate through the circular plate 92. There are four cylinders 8. The four cylinders 8 are arranged in a circular array outside the circular plate 92. The number of connecting frames 93 is matched with the number of cylinders 8. When the motor 91 starts, it can drive all the cylinders 8 to rotate. The leftmost cylinder 8 is located directly above the feed inlet 3.

[0035] The cylinder 8 contains a mixing bowl 10, the bottom of which is flat. When the mixing bowl 10 is located at the rear or right side, its bottom will fit against the upper surface of the tank 1, allowing it to be placed stably. A counterweight 11 is fixedly connected to the upper surface of the mixing bowl 10, embedded within it to prevent obstruction of material pouring. When the cylinder 8 rotates to the left, the counterweight 11 is located directly in front of the cylinder 8, at which point the cylinder 8 moves directly above the feed inlet 3. The bottom limit is automatically released, and the counterweight 11 makes the center of gravity of the cylinder 8 move closer to the front. At this time, the cylinder 8 will flip forward under the action of the counterweight 11, so that the material placed inside the cylinder 8 can slide into the tank 1. When the mixing bowl 10 is flipped, the crossbar 6 will limit the mixing bowl 10. When the motor 91 starts and continues to drive the cylinder 8 and the mixing bowl 10 to rotate, the mixing bowl 10 will be pushed to a horizontal state under the action of the crossbar 6, and can return to the top of the tank 1 to remain horizontal.

[0036] A limiting unit 12 is provided on the outer side of the ingredient bowl 10. The limiting unit 12 includes a groove 121 and a slider 122. The groove 121 is formed on the inner wall surface of the cylinder 8. The side of the groove 121 near the ingredient bowl 10 passes through the cylinder 8. The slider 122 is slidably connected inside the groove 121. The slider 122 can move linearly up and down inside the groove 121. A rotating shaft 123 is rotatably connected to the side surface of the slider 122 near the ingredient bowl 10. The end of the rotating shaft 123 near the ingredient bowl 10 is fixedly connected to the outer wall of the ingredient bowl 10. The ingredient bowl 10 is rotatably connected to the slider 122 through the rotating shaft 123, thereby allowing the ingredient bowl 10 to rotate. At the same time, the ingredient bowl 10 can move linearly up and down relative to the cylinder 8 through the cooperation of the groove 121 and the slider 122.

[0037] When motor 91 starts and drives the mixing bowl 10 to the front, the mixing bowl 10 can move along the inclined surface of the side of the weighing device 7 to the top of the weighing device 7. At the same time, the weighing device 7 can automatically peel the mixing bowl 10. Then, the operator can add modifiers, additives or auxiliary materials into the mixing bowl 10. When the weight of the material reaches the required value, motor 91 can be started again to drive the cylinder 8 and the mixing bowl 10 with the prepared material to rotate clockwise to the top of the feed inlet 3.

[0038] Reference Figure 6An arc plate 13 is fixedly connected to the upper surface of the tank body 1, and an arc-shaped baffle 14 is fixedly connected to the upper surface of the arc plate 13. The bottom surface of the arc-shaped baffle 14 is in contact with the upper surface of the cylinder 8. The arc-shaped baffle 14 is fixedly connected to the top of the tank body 1 via the arc plate 13. A fixing plate 15 is fixedly connected to the left front end of the arc-shaped baffle 14, and a rotating plate 16 is fixedly connected to the right front end of the arc-shaped baffle 14. When the rotating plate 16 is flipped to the left, it can rest on the fixing plate 15 for stable placement. At this time, the arc-shaped baffle 14 can be placed on the rotating plate 16. In coordination, the top of all cylinders 8 is shielded to reduce the risk of dust and impurities falling into the mixing bowl 10. At the same time, when it is necessary to add materials into the mixing bowl 10, the rotating plate 16 can be flipped to the right and placed above the arc-shaped baffle 14, thereby opening the front side of the arc-shaped baffle 14. When the cylinder 8 drives the mixing bowl 10 to rotate directly above the weighing device 7, it will be located directly below the front side of the arc-shaped baffle 14. At this time, the staff can add materials into the mixing bowl 10 located on the front side for weighing.

[0039] Working principle: After aggregates, minerals, and fillers are added to the tank 1 through the feed hopper 2, the agitator can be started for mixing. During the mixing process, the motor 91 can be started to drive multiple cylinders 8 to rotate. When the cylinders 8 rotate to the front, the mixing bowl 10 will move directly above the weighing device 7. At this time, modifiers, additives, and auxiliary materials can be added to the mixing bowl 10 for weighing. After the required weight is reached, the motor 91 can be started again to drive the mixing bowl 10 to rotate clockwise. When the mixing bowl 10 rotates to the feed inlet 3... When directly above, the limiting position on the bottom of the mixing bowl 10 is released, allowing the mixing bowl 10 to quickly flip forward under the action of the counterweight 11, automatically pouring the material into the tank 1 for stirring and mixing. At this time, the next cylinder 8 will move the mixing bowl 10 inside to the weighing device 7 for weighing. The pouring and weighing are carried out simultaneously, which can further improve the mixing efficiency. At the same time, multiple mixing bowls 10 can be used to mix and pour materials of different properties, thereby avoiding the adhesion of fixed materials caused by liquid materials, which would affect the mixing accuracy.

[0040] After the material inside a mixing bowl 10 is poured out, the motor 91 can be started to rotate the mixing bowl 10. This allows the mixing bowl 10, located directly above the feed inlet 3, to automatically return to a horizontal position under the action of the crossbar 6, facilitating subsequent movement. After the ingredients are added, the operator can flip the rotating plate 16 to the left to cooperate with the fixed plate 15, thus shielding the top of all the cylinders 8 and reducing the risk of dust and impurities entering the mixing bowl 10.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
