When the quantitative plate 13 rises to the position of the induction ring, the induction ring 15 and the induction block 14 are inductively coupled to each other. , thereby controlling the screw pump 7 to stop feeding, and starting the electric push rod 11 to drive the extrusion rod 12 to press the quantitative plate 13 downward, so that a quantitative amount of asphalt can be discharged and used, realizing precise control of the asphalt; a cleaning mechanism 2 is provided inside the hopper 3, and the cleaning mechanism 2 is used to scrape the asphalt on the inner wall of the hopper 3; the bottom of the quantitative cylinder 9 is connected to the discharge pipe 17, and the left side of the outer wall of the hopper 3 is connected to the feed port 26; the front side of the outer wall of the quantitative cylinder 9 is provided with a scale 18, and the top right side of the base 1 is fixedly connected to a support frame 19;
[0033] Specifically, the base 1 serves as the supporting foundation of the entire device to ensure stable operation of the device. A support frame 19 is fixed to the right side of the top to assist in supporting other components. The hopper 3 is used to store the asphalt raw materials to be processed. A sealing cover 6 is fixed to the top to effectively isolate the external environment and prevent dust from entering and contaminating the asphalt. An inner cylinder 5 is fixed inside the hopper 3. A heating device 4 is installed on the outer wall of the inner cylinder 5 to uniformly heat the asphalt to ensure its fluidity during the processing. The heating device 4 is close to the outer wall of the inner cylinder 5 and adopts an efficient and energy-saving heating method to accurately control the asphalt temperature according to process requirements to avoid problems caused by overheating or insufficient temperature.

[0034] Reference Figure 1 、 Figure 3 and Figure 5 The cleaning mechanism 2 includes a servo motor 201. The bottom of the servo motor 201 is fixedly connected to the top of the sealing cover 6. The output end of the servo motor 201 passes through the top of the sealing cover 6 and is fixedly connected to the rotating rod 202. By starting the servo motor 201, the rotating rod 202 is driven to rotate at high speed. At the same time, the barrel cover 6 ensures the stability of the servo motor 201 during operation. The outer walls of the rotating rod 202 are fixedly connected with connecting columns 203. The left and right ends of the two connecting columns 203 are slidably connected to multiple sliding rods 204. The outer walls of the multiple sliding rods 204 are fixedly connected with springs. 205, a plurality of sliding rods 204 are fixedly connected to the ends away from each other with scrapers 206, and the sliding rods 204 are connected by a plurality of connecting columns 203 on the outer wall of the rotating rod 202, so that the sliding rods 204 can be extended for use.

The spring 205 can make the scrapers 204 on the sliding rods 204 adapt to inner cylinders 5 of different sizes, thereby improving practicality. At the same time, the scrapers 204 can scrape off the asphalt on the inner wall of the inner cylinder 5 when rotating at high speed, so as to avoid the asphalt solidifying and being difficult to clean in the later stage;
[0035] Specifically, the servo motor 201 serves as a power source, and its bottom is tightly connected to the sealing cover 6 through a sturdy fixing device, ensuring the stability and safety of the servo motor 201 when running at high speed. The sealing cover 6 not only serves to isolate the external environment, but also provides necessary support for the servo motor 201 through its structural design, preventing the servo motor 201 from vibrating and deflecting during operation. The output end of the servo motor 201 cleverly penetrates the top of the sealing cover 6 and achieves a seamless connection with the rotating rod 202. This connection method not only simplifies the transmission path, but also improves the transmission efficiency. When the servo motor 201 is started, its powerful torque is transmitted to the rotating rod 202 through the output end, driving it to rotate at high speed. The rotating rod 202 is a key component of the cleaning mechanism, and a plurality of connecting columns 203 are evenly distributed on its outer wall. These connecting columns 203 not only serve as support and fixation, but also achieve flexible connection with the sliding rod 204 through its special design; the left and right ends of the two connecting columns 203 enable the plurality of sliding rods 204 to slide freely inside them. The design enables the sliding rod 204 to expand or contract according to the actual size of the inner cylinder 5, thereby achieving wide adaptability to inner cylinders of different specifications; the outer wall of the sliding rod 204 is fixedly connected with a spring 205. The introduction of the spring 205 provides the sliding rod 204 with the necessary elastic support and buffering effect. During the cleaning process, when the scraper 206 encounters uneven parts or stubborn asphalt residues on the inner wall of the inner cylinder 5, the spring 205 can absorb part of the impact and vibration to protect the scraper from damage; at the same time, the elastic reaction force of the spring can also help the scraper better fit the wall of the inner cylinder and improve the cleaning effect. The end of the sliding rod 204 away from the connecting column 203 is fixedly connected with the scraper 206. The scraper 206 is the direct working part of the cleaning mechanism, and its material and shape are carefully designed and selected. During high-speed rotation, the scraper 206 can use its sharp edge to easily scrape off the asphalt residues on the inner wall of the inner cylinder 5. This efficient cleaning method not only avoids the problem of late solidification and difficulty in cleaning of asphalt, but also greatly improves the cleaning efficiency and operating stability of the equipment.
[0036] Reference Figure 1 and Figure 2 , a controller 21 is fixedly connected to the top of the support frame 19, and the controller 21 is electrically connected to the servo motor 201, the heating device 4, the screw pump 7 and the induction ring 15 respectively. The outer wall of the metering cylinder 9 is fixedly connected with a reinforcement plate 20 on all sides, and the bottoms of the multiple reinforcement plates 20 are fixedly connected to the top of the support frame 19. A slide groove 22 is opened on the right side of the top of the base 1, and a collection box 23 is slidably connected to the inside of the slide groove 22. A handle 24 is fixedly connected to the front side of the collection box 23, and an anti-slip sleeve 25 is fixedly connected to the outer wall of the handle 24;
[0037] Specifically, the controller 21 can be used to conveniently perform simple operational control on the operating equipment on the entire device. The reinforcement plate 20 and the support frame 19 simultaneously ensure the stability and firmness of the metering cylinder 9. The collection box 23 can conveniently store the measured asphalt and transport it through the handle 24.
[0038] Working principle: First, the asphalt inside the hopper 3 is sealed by the sealing cover 6 to prevent dust from splashing. At the same time, the heating device 4 is started to heat the asphalt in the inner tube 5 to ensure the fluidity of the asphalt. The asphalt is transferred into the metering cylinder 9 through the conveying pipe 8 by the screw pump 7. At the same time, when the asphalt enters the metering cylinder 9, the asphalt will drive the quantitative plate 13 to move upward. According to the actual total amount required, the position of the induction ring 15 on the outer wall of the metering cylinder 9 is adjusted, and the reinforcement ring 16 is rotated to fix the induction ring 15 on the outer wall of the metering cylinder 9. When the quantitative plate 13 rises to the position of the induction ring, the induction ring 15 and the induction block 14 are inductively coupled to each other, thereby controlling the screw pump 7 to stop feeding, and starting the electric push rod 11 to drive the extrusion rod 12 to press the quantitative plate 13 downward, so that a certain amount of asphalt can be discharged and used, thereby achieving precise control of the asphalt.
[0039] And by starting the servo motor 201 to drive the rotating rod 202 to rotate at high speed, the sliding rod 204 is connected through multiple connecting columns 203 on the outer wall of the rotating rod 202, so that the sliding rod 204 can be extended for use. At the same time, a spring 205 is installed at the connection between the sliding rod 204 and the connecting column 203. The spring 205 can make the scraper 204 on the sliding rod 204 adapt to inner cylinders 5 of different sizes, thereby improving practicality. At the same time, the scraper 204 can scrape off the asphalt on the inner wall of the inner cylinder 5 when rotating at high speed, so as to avoid solidification and difficulty in cleaning in the later stage.
