Description

Technical Field

[0001] The utility model relates to the technical field of regenerated asphalt mixing, in particular to a regenerated asphalt product mixer. Background Art

[0002] Recycled asphalt mixing refers to the process of recycling waste asphalt materials (such as old pavements, waste asphalt mixtures, etc.) and mixing them with new asphalt materials to make new asphalt mixtures. This method can not only effectively reduce waste, but also reduce the use of new materials, and has environmental and economic benefits.

[0003] When mixing recycled asphalt raw materials, a recycled asphalt mixer is generally used to mix the raw materials. The recycled asphalt mixer is generally equipped with a control system, a feeding mechanism, a discharging mechanism, a stirring motor and a stirring rod. After the material is loaded through the feeding mechanism, the stirring motor drives the stirring rod to achieve stirring and mixing of the material. After the stirring and mixing is completed, the material is discharged through the discharging mechanism.

[0004] Based on the existing structural composition of the above-mentioned recycled asphalt mixer, it can be known that when mixing materials, the mixing is generally carried out in one direction, so the materials will move in one direction, which is not convenient for sufficient mixing of the materials. At the same time, the materials are easily attached to the inner wall and cannot be mixed. Therefore, the utility model designs a recycled asphalt product mixer that can improve the mixing effect to solve this existing technical defect. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 5 A recycled asphalt product mixer in this embodiment includes a support base 1, a mixing drum 2, a cover 3, a motor cover 4, a mixing motor 6, a mixing rod 7, a movable seat 5, an upper hopper 17 and a discharge pipe 21.

[0029] In this embodiment, a mixing drum 2 is fixedly mounted on the top of the supporting base 1, a cover 3 is fixedly mounted on the top of the mixing drum 2 by fastening screws, a motor cover 4 is fixedly mounted on the top of the cover 3, a stirring motor 6 is fixedly mounted inside the motor cover 4, a movable seat 5 is fixedly mounted on the bottom wall of the mixing drum 2, a stirring rod 7 rotatably connected to the movable seat 5 is fixedly mounted on the output shaft of the stirring motor 6, an upper hopper 17 is connected to the top of the cover 3, and a discharge pipe 21 is connected to the right side of the mixing drum 2.

[0030] A control box for controlling the operation and power supply of the entire equipment system is fixedly mounted on the front surface of the mixing drum 2 .

[0031] An on-off valve is provided on the outside of the discharge pipe 21 .

[0032] The outside of the stirring rod 7 in this embodiment is provided with a clockwise stirring mechanism for rotating and stirring in a clockwise direction.

[0033] It should be noted that the clockwise stirring mechanism includes a clockwise stirring horizontal rod 8 fixed to the outside of the stirring rod 7, and a number of clockwise stirring vertical rods 9 distributed at equal distances in the horizontal direction are fixed on the top of the clockwise stirring horizontal rod 8.

[0034] In this embodiment, a transmission mechanism is provided between the stirring rod 7 and the motor cover 4 .

[0035] A counterclockwise stirring mechanism which rotates counterclockwise is provided on the transmission mechanism.

[0036] It should be noted that the counterclockwise stirring mechanism includes a rotating sleeve 14 which is sleeved on the outside of the stirring rod 7 and passes through the cover 3. A counterclockwise stirring cross bar 12 located in the stirring drum 2 is fixedly installed on the outside of the rotating sleeve 14. The bottom of the counterclockwise stirring cross bar 12 is fixedly installed with a number of counterclockwise stirring vertical rods 13 which are evenly distributed laterally.

[0037] The counterclockwise stirring vertical rod 13 and the clockwise stirring vertical rod 9 are cross-distributed, and the rotating sleeve 14 and the stirring rod 7 are cocentric.

[0038] The transmission mechanism includes a circular groove 10 formed on the outside of the rotating sleeve 14 and a gear wheel 15 fixedly mounted on the outside of the rotating sleeve 14 and the stirring rod 7 .

[0039] A movable sleeve 11 fixedly mounted on the top of the cover 3 is rotatably connected in the circular groove 10 , and two cylindrical gears 16 symmetrically distributed on the left and right and rotatably connected to the motor cover 4 are meshed between the gear discs 15 .

[0040] The counterclockwise stirring mechanism in this embodiment is provided with a scraping mechanism that contacts the inner wall of the stirring drum 2 and scrapes off the material.

[0041] It can be understood that the scraping mechanism includes a telescopic spring 18 fixedly installed inside the left and right sides of the counterclockwise stirring cross bar 12, and the other end of the telescopic spring 18 is fixed with a moving rod 19 that penetrates and extends to the outside of the counterclockwise stirring cross bar 12, and the other end of the moving rod 19 is fixed with a scraper 20 that contacts the inner wall of the mixing drum 2.

[0042] Both sides of the counterclockwise stirring cross bar 12 are provided with cavities for installing the telescopic spring 18. Both sides of the counterclockwise stirring cross bar 12 are fixed with covers by fastening screws. The movable rod 19 passes through the cover, which makes it easy to replace the telescopic spring 18 by removing the cover.

[0043] When the scraper 20 contacts the inner wall of the mixing drum 2, the telescopic spring 18 is in a compressed state.

[0044] The length of the scraper 20 is equal to the vertical length between the top wall and the bottom wall of the inner cavity of the mixing drum 2.

[0045] The working principle of the above embodiment is:

[0046] The stirring motor 6 drives the stirring rod 7 to rotate on the movable seat 5, and simultaneously drives the clockwise stirring horizontal rod 8 and the clockwise stirring vertical rod 9 to rotate clockwise to stir the mixed material in the mixing drum 2 clockwise;

[0047] In addition, when the stirring rod 7 rotates, the toothed disc 15 located on the stirring rod 7 is driven to rotate. The toothed disc 15 is driven to rotate by the meshing transmission with the cylindrical gear 16. At the same time, the cylindrical gear 16 is driven to rotate by the meshing transmission with the toothed disc 15 fixedly installed on the rotating sleeve 14. Under the action of the movable sleeve 11 on the limited rotation of the rotating sleeve 14 through the circular groove 10, the cylindrical gear 16 drives the rotating sleeve 14 on the toothed disc 15 to rotate counterclockwise, thereby driving the counterclockwise stirring horizontal rod 12 and the counterclockwise stirring vertical rod 13 to rotate counterclockwise synchronously to stir the material counterclockwise, and cooperate with the cross-equal distribution of the clockwise stirring vertical rod 9 and the counterclockwise stirring vertical rod 13 to improve the uniform mixing effect of the material.

[0048] Moreover, during the counterclockwise rotation of the stirring cross bar 12, the elastic expansion and contraction of the telescopic spring 18 causes the scraper 20 on the telescopic spring 18 to fit tightly against the inner wall of the stirring drum 2 and rotate along with the counterclockwise stirring cross bar 12, thereby preventing the material from adhering to the inner wall and being unable to be stirred, thereby further improving the stirring effect.

[0049] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.
