DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-5 The utility model provides a technical solution: an asphalt pressurized infiltration mixing device for roadbed reinforcement, comprising a box body 1, a feed pipe 2, a discharge pipe 3, a cylinder 4, a push block 5, a pressure plate 6, a cylinder 7, a telescopic rod 8, a stirring rod 9, a steam pipe 10, a turbine 11, a bevel gear 12, a bevel gear 2 13, a turntable 1 14, a turntable 2 15, and a scraper 16.

[0030] This device has the effect of preventing feed residue, specifically:

[0031] A scraping structure is provided inside the feed pipe 2. The scraping structure uses a scraper rod 16 to generate a force on the inner wall of the feed pipe 2 to prevent asphalt from remaining inside the feed pipe 2. The scraping structure includes a steam pipe 10. The steam pipe 10 is spirally installed on the outer surface of the box body 1. A turbine 11 is rotatably provided on the inner wall of the outlet end of the steam pipe 10. One end of the rotating shaft of the turbine 11 is connected to a bevel gear 12. A turntable 14 is mounted on the upper surface of the box body 1. A bevel gear 13 is provided at one end of the rotating shaft of the turntable 14. The bevel gear 12 and the bevel gear 13 are meshed. A plurality of protrusions are provided on the surface of the turntable 14. A scraper rod 16 is rotatably provided on the inner wall of the feed pipe 2. The upper end of the scraper rod 16 is connected to a turntable 15. The outer surface of the turntable 15 is provided with protrusions, and the turntable 15 is in vertical contact with the turntable 14.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, steam is introduced into the steam pipe 10 to keep the device warm. When the steam is discharged from the other end of the steam pipe 10, the steam drives the turbine 11 to rotate. The rotation of the turbine 11 drives the bevel gear 12 to rotate. The rotation of the bevel gear 12 drives the bevel gear 2 13 to rotate. The rotation of the bevel gear 2 13 drives the turntable 14 to rotate. When the turntable 14 rotates, it continuously drives the turntable 2 15 to rotate. When the turntable 2 15 rotates, the turntable 2 15 drives the scraper 16 to rotate on the inner wall of the feed pipe 2 to prevent asphalt from remaining on the inner wall of the feed pipe 2.

[0033] This device has the effect of pressurizing and stirring asphalt at the same time, specifically:

[0034] The surface of the box body 1 is penetrated with a feed pipe 2, the bottom surface of the box body 1 is provided with a discharge pipe 3, and the interior of the box body 1 is provided with a pressurizing structure, which increases the pressure inside the box body 1 by the movement of a pressing plate 6, so as to facilitate the mixing of the asphalt raw materials. The pressurizing structure includes a cylinder 4, which is mounted on the upper surface of the box body 1, and the lower end of the cylinder 4 penetrates the upper surface of the box body 1 and is connected with two push blocks 5, and the lower end of the push block 5 is provided with a press plate 6, and the outer surface of the press plate 6 is slidably connected to the inner wall of the box body 1, and the upper surface of the press plate 6 is provided with an annular groove, and the push plate 6 is provided with a push plate 6. The block 5 is slidably connected with the annular groove on the surface of the pressing plate 6, and two push blocks 5 are symmetrically arranged on the upper surface of the pressing plate 6. The surface of the pressing plate 6 is provided with a stirring structure, which includes a cylinder 7, which is installed on the bottom surface of the box body 1. The upper half of the outer surface of the cylinder 7 is provided with a spiral groove, and the height of the spiral groove on the surface of the cylinder 7 is higher than the height of the maximum volume of asphalt that the device can accommodate. The pressing plate 6 is rotatably connected with the threaded groove on the surface of the cylinder 7. A telescopic rod 8 is provided on the lower surface of the pressing plate 6, and a plurality of stirring rods 9 are provided on the outer surface of the telescopic rod 8;

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, asphalt is discharged into the box body 1 through the feed pipe 2, and the cylinder 4 is started. The cylinder 4 drives the push block 5 to move downward. When the push block 5 moves downward, the push block 5 drives the pressure plate 6 to move downward, and the pressure plate 6 rotates in the spiral groove of the cylinder 7, so that the pressure plate 6 rotates while descending. When the pressure plate 6 moves downward, the gas content in the box body 1 remains unchanged, and the space is reduced, so that the pressure in the box body 1 increases, and the asphalt can be better mixed in the pressurized environment. When the pressure plate 6 rotates and moves downward on the surface of the cylinder 7, the rotation of the pressure plate 6 drives the telescopic rod 8 to rotate, and the rotation of the telescopic rod 8 drives the stirring rod 9 to rotate, so as to fully mix the asphalt in the box body 1. The distance that the pressure plate 6 moves on the outer surface of the cylinder 7 is equal to the height of the spiral groove on the outer surface of the cylinder 7. Since the height of the spiral groove on the surface of the cylinder 7 is higher than the height of the maximum volume of asphalt that the device can accommodate, the asphalt in the device will not adhere to the groove on the surface of the cylinder 7, thereby affecting the movement of the pressure plate 6.

[0036] Working principle: When using the asphalt pressurized infiltration mixing device for roadbed reinforcement, steam is introduced into the steam pipe 10 on the outer surface of the box 1 to keep the device warm and prevent the asphalt from changing in performance due to temperature changes. A turbine 11 is set at one end of the steam pipe 10. The turbine 11 rotates under the drive of steam to drive the scraper rod 16 in the feed pipe 2 to move to prevent asphalt residue. The cylinder 4 is started, and the cylinder 4 drives the pressing plate 6 to move downward on the inner wall of the box 1 to increase the pressure in the box 1, so that the asphalt is more fully mixed in the pressurized environment. When the pressing plate 6 descends, the pressing plate 6 rotates under the drive of the spiral groove on the surface of the cylinder 7. The rotating pressing plate 6 drives the stirring rod 9 on the lower surface to fully stir the asphalt, which increases the overall practicality. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
