[0029] Example 1

[0030] Reference Figure 1-Figure 5The first embodiment of the present application provides an asphalt output device for an asphalt tank, comprising a tank body 10, a stirring shaft 20, a scraper assembly 30 and a lifting assembly 40. The bottom of the tank body 10 has a discharge channel 12; the stirring shaft 20 is rotatably arranged in the tank body 10, and a driving member 21 and a spiral blade 23 are arranged on the stirring shaft 20, and the outer wall of the spiral blade 23 matches the inner wall of the discharge channel 12; the scraper assembly 30 includes a clutch 33 for cooperating with the driving member 21 and a scraper body 34 that can abut against the inner wall of the tank body 10; the lifting assembly 40 is arranged outside the tank body 10, one end of the stirring shaft 20 passes through the outer wall of the tank body 10 and is connected to the lifting assembly 40, and the lifting assembly 40 is used to drive the stirring shaft 20 to move along its axial direction, so that the spiral blade 23 can selectively enter the discharge channel 12, and the driving member 21 can selectively cooperate with the clutch 33.

[0031] In this embodiment, at least three legs are provided at the lower end of the tank body 10, and a lifting lug is provided at the upper end of the tank body 10, so as to facilitate the lifting of the tank body 10 through the lifting lug. The discharge channel 12 is provided at the middle position of the bottom of the tank body 10, and the bottom wall of the lower end of the tank body 10 can be funnel-shaped, which can guide the asphalt at the bottom of the tank body 10 and guide the asphalt into the discharge channel 12. The upper end outer wall of the tank body 10 is provided with a through mounting hole, and the mounting hole is used for the stirring shaft 20 to pass through. A bearing can be provided in the mounting hole, and the upper end of the stirring shaft 20 is penetrated and provided on the bearing. The driving member 21 and the spiral blade 23 are fixedly provided on the stirring shaft 20, and move and rotate synchronously with the stirring shaft 20. The stirring shaft 20 moves up and down to selectively connect the driving member 21 with the clutch 33. When the driving member 21 is connected with the clutch 33, the spiral blade 23 is located in the discharge channel 12. At this time, the stirring shaft 20 stirs the asphalt in the tank body 10, and the scraper body 34 rotates with the stirring shaft 20 to scrape the inner wall of the tank body 10. The spiral blade 23 squeezes the asphalt in the discharge channel 12 and discharges it from the discharge channel 12; when the spiral blade 23 is located outside the discharge channel 12, the driving member 21 and the clutch 33 are in a separated state. At this time, the scraper assembly 30 is stationary in the tank body 10, and the spiral blade 23 is located above the discharge channel 12. The stirring shaft 20 stirs the asphalt in the tank body 10 to make the temperature of the asphalt uniform, reduce the probability of local asphalt temperature being too cold and causing agglomeration, etc.

[0032] Example 2

[0033] As an optional implementation, refer to Figure 1 and Figure 2 , Figure 1M in the figure represents the first section of the stirring shaft 20, N represents the second section of the stirring shaft 20, and P represents the third section of the stirring shaft 20. This embodiment provides a specific structure of the stirring shaft 20, specifically: the stirring shaft 20 includes a first section, a second section and a third section distributed along its axial direction, a driving member 21 is arranged in the first section, a plurality of stirring blades 22 for stirring asphalt are arranged in the second section, and a spiral blade 23 is arranged in the third section.

[0034] In this embodiment, the depth of asphalt contained in the tank body 10 is generally located in the second and third sections, and the asphalt is generally not immersed in the first section, so as to ensure that the clutch 33 can be normally engaged with the driving member 21. The stirring blade 22 of the second section can stir the asphalt in the tank body 10. The spiral blade 23 of the third section is used to squeeze and push the asphalt when it is located in the discharge channel 12, thereby increasing the discharge speed of the asphalt; when the spiral blade 23 is located outside the discharge channel 12, the spiral blade 23 can also stir the asphalt in the tank body 10.

[0035] Example 3

[0036] As an optional implementation, refer to Figure 3 and Figure 4 The present embodiment provides a specific structure of a scraper assembly 30, specifically: the scraper assembly 30 also includes a positioning ring 31, the positioning ring 31 is sleeved on the periphery of a clutch 33, the positioning ring 31 and the clutch 33 are connected to each other through a connecting rod 32, the upper end of the scraper body 34 is connected to the positioning ring 31, the clutch 33 is sleeved on the periphery of the stirring shaft 20 in an annular shape, the inner wall of the clutch 33 has protrusions 331 distributed in an annular shape, and slots 332 are formed between adjacent protrusions 331, and the outer wall of the driving member 21 is provided with a block 211 for cooperating with the slot 332.

[0037] Optionally, the positioning ring 31 is provided with a plurality of screw holes arranged in a ring shape, and the upper end of the scraper body 34 is provided with a screw rod for cooperating with the screw holes.

[0038] In this embodiment, the positioning ring 31 has a circular shape, and the outer wall shape of the positioning ring 31 matches the inner wall shape of the tank body 10. An annular flange may be provided on the outer wall of the positioning ring 31, and an annular placement groove is provided on the inner wall of the tank body 10. The flange is located in the placement groove, which plays an auxiliary positioning role for the positioning ring 31, reduces the probability of the positioning ring 31 moving in the height direction, and improves the stability of the positioning ring 31 during rotation. The clutch 33 is sleeved on the periphery of the stirring shaft 20. During the lifting and lowering of the stirring shaft 20, the clutch 33 will not follow the lifting and lowering of the stirring shaft 20. When the stirring shaft 20 moves downward, the driving member 21 moves to the position of the clutch 33, and the block 211 on the driving member 21 enters into the slot 332 between the adjacent protrusions 331 on the clutch 33. The driving member 21 and the clutch 33 form a circumferential limiting structure. The rotation of the stirring shaft 20 drives the clutch 33 to rotate synchronously, thereby realizing the rotation of the scraper assembly 30. The scraper body 34 of the scraper assembly 30 abuts against the inner wall of the tank body 10. During the rotation of the scraper body 34 around the axis of the stirring shaft 20, the scraper body 34 scrapes off the asphalt attached to the inner wall of the tank body 10, so that the asphalt attached to the inner wall can directly fall to the bottom of the tank body 10, which is convenient for discharge. The scraper body 34 is connected to the positioning ring 31 by a screw (not shown in the figure), which is convenient for quick disassembly and installation of the scraper body 34. The number of scraper bodies 34 can be installed and the distance between adjacent scrapers can be adjusted according to actual use requirements. The scraper body 34 is connected by a screw, and the inclination of the scraper body 34 can be adjusted. According to the inner diameter of the tank body 10, the angle formed between the scraper body 34 and the inner wall of the tank body 10 can be changed.

[0041] Optionally, all the guide plates 35 are inclined clockwise or counterclockwise.

[0042] In this embodiment, the guide plate 35 is located on the bottom wall of the tank body 10. When the bottom wall of the tank body 10 is a horizontal plane, the guide plate 35 is also in a horizontal state. When the bottom wall of the tank body 10 is funnel-shaped, the guide plate 35 is in an inclined state that matches the bottom wall of the tank body 10. The guide plate 35 rotates with the rotation of the scraper assembly 30. When it is necessary to discharge asphalt, the guide plate 35 can stir the asphalt at the bottom of the tank body 10 and guide the asphalt at the bottom of the tank body 10 to flow to the discharge channel 12. When most of the asphalt in the tank body 10 is discharged, the guide plate 35 can scrape off the asphalt attached to the bottom wall of the tank body 10 and guide the asphalt attached to the bottom wall of the tank body 10 to the discharge channel 12 for discharge. By tilting all the guide plates 35 in the same direction, clockwise or counterclockwise at the same time, it is more conducive to guiding the asphalt to the discharge channel 12 during the rotation of the guide plates 35 around the axis of the stirring shaft 20.
