Description

Technical Field

[0001] This utility model relates to the field of mixing machines, and in particular to a novel asphalt spraying device for mixing machines. Background Technology

[0002] A kneader is a device that mixes solid carbonaceous materials and binders uniformly at a certain temperature while applying shear force to achieve a kneading effect. It mainly completes the kneading of dry materials and binder asphalt, giving the paste strong plasticity. Under the action of the kneader, asphalt impregnates and fuses the particles and powders, and coats the surface of the particles with a uniform asphalt film, forming a paste with good plasticity. During the mixing process, asphalt needs to be sprayed into the kneader to mix with the dry materials, requiring the use of an asphalt spraying device.

[0003] According to the discharge structure of a kneading machine disclosed in Chinese Patent Publication No. CN221156499U, the kneading machine body includes a damping component placed below the kneading machine body. The discharge component is housed within the inner cavity of the kneading machine body. The discharge component includes a first hydraulic cylinder and a second hydraulic cylinder. A first sliding plate is provided at the top of the output end of the first hydraulic cylinder, and a first sealing frame is provided on the outer wall of the first sliding plate. A second sliding plate is provided on the right side of the output end of the second hydraulic cylinder, and a second sealing frame is provided on the outer wall of the second sliding plate. The damping component is located below and cooperates with the first hydraulic cylinder. The second sealing frame scrapes away any material adhering to the first sliding plate, thus avoiding material waste. The damping spring damper reduces vibrations generated during operation, thereby improving the stability of the device.

[0004] However, the above-mentioned device directly places the dry material and binder asphalt into the mixer, resulting in a relatively concentrated addition of the dry material and binder asphalt before mixing. This leads to uneven mixing of the binder asphalt and dry material, affecting the mixing efficiency and quality. Utility Model Content

[0008] Furthermore, the asphalt spraying mechanism includes gears, which are fixedly connected to the output shaft of a dual-head motor. Gear rings mesh on the surface of the gears, and spray holes are opened on the surface of the gear rings. A fixing block is rotatably connected to the inner wall of the gear rings, and the fixing block is fixedly connected to the top wall of the kneading machine body.

[0012] Furthermore, a groove is provided above the toothed ring, and an asphalt pipe is slidably connected within the groove.

[0013] The working principle and application principle of this utility model are as follows: Dry materials enter the mixing machine body through the feed pipe, and binder asphalt is placed at the feed inlet of the mixing tank. Upon reaching the mixing tank, the controller starts the servo motor and heating tube. The servo motor drives the stirring rod to rotate, causing the stirring rod to stir the binder asphalt and prevent it from solidifying. At the same time, the heating tube heats the binder asphalt, and the asphalt pump is started, causing the asphalt pump to drive the outlet pipe to transport the binder asphalt and stir it to prevent it from solidifying. The dual-head motor drives the gear to rotate, causing the gear to drive the toothed ring to rotate on the inner wall of the fixed block.

The dual-head motor drives the rotating shaft to rotate, which in turn drives the rotating wheel. The rotating wheel, via a belt, drives the mixing wheel to rotate, which in turn drives the mixing rod to rotate. The mixing rod mixes the dry material and binder asphalt on the inner wall of the mixer. The heating pipe heats the inner wall of the mixer to prevent the binder asphalt from solidifying. After completion, the valve is opened, allowing the mixture to be discharged through the discharge pipe, facilitating uniform spraying of the asphalt and improving mixing efficiency and quality.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: Dry material enters the kneading machine body through the feed pipe, and binder asphalt is placed in the asphalt mixing mechanism. The asphalt mixing mechanism and the double-headed motor are started by the controller. The double-headed motor drives the asphalt spraying mechanism to rotate, so that the asphalt mixing mechanism carries the binder asphalt to the asphalt spraying mechanism. The rotation of the asphalt spraying mechanism sprays the asphalt into the kneading machine body, so that the double-headed motor drives the rotating shaft to rotate, and the rotating shaft drives the rotating wheel to rotate, so that the rotating wheel drives the mixing wheel to rotate through the belt, so that the mixing wheel drives the mixing rod to rotate, so that the mixing rod stirs and mixes the dry material and binder asphalt on the inner wall of the kneading machine body. The heating pipe heats the inner wall of the kneading machine body to prevent the binder asphalt from solidifying.

[0019] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0020] A novel asphalt spraying device for a kneading machine, as described in this specific embodiment, is as follows: Figure 1-5As shown, a novel asphalt spraying device for a kneader includes a kneader body 1, which mixes dry materials and binder asphalt. A feed pipe 2 is fixedly connected to one end of the top of the kneader body 1 for placing the dry materials. Support legs 3 are fixedly connected to the other end of the kneader body 1 for supporting the kneader body 1. A discharge pipe 4 is fixedly connected to one end of the bottom of the kneader body 1 for discharging the mixed materials. A switch valve 5 is fixedly connected to the inner wall of the discharge pipe 4 for opening and closing the discharge pipe 4, facilitating material mixing and discharge. A heating pipe 12 is fixedly connected to the inner wall of the kneader body 1 to heat the dry materials and binder asphalt inside the kneader body 1, facilitating mixing. A controller 14 is fixedly connected to the surface of the kneader body 1 for controlling electrical components. An asphalt mixing mechanism is fixedly connected to one side of the surface of the kneader body 1. The asphalt mixing mechanism mixes the asphalt to prevent it from solidifying into lumps. A double-headed motor 6 is fixedly connected to one side of the surface of the kneading machine body 1. The output shafts of the double-headed motor 6 are both fixedly connected to an asphalt spraying mechanism and a rotating shaft 7. The double-headed motor 6 drives the asphalt spraying mechanism and the rotating shaft 7 to rotate. The asphalt spraying mechanism facilitates the spraying of asphalt, allowing the asphalt to be evenly mixed with the dry materials during the mixing process. The rotating shaft 7 is rotatably connected to one side of the surface of the kneading machine body 1. A rotating wheel 8 is fixedly connected to one end of the rotating shaft 7. A belt 9 is meshed on the surface of the rotating wheel 8. An agitating wheel 10 is meshed on the inner wall of one side of the belt 9. An agitating rod 11 is fixedly connected to one end of the agitating wheel 10. The agitating rod 11 is rotatably connected to the inner wall of the kneading machine body 1. The rotating shaft 7 drives the rotating wheel 8 to rotate, which in turn drives the agitating wheel 10 to rotate via the belt 9. The agitating wheel 10 drives the agitating rod 11 to rotate, causing the agitating rod 11 to mix the dry materials and binder asphalt on the inner wall of the kneading machine body 1.

[0021] Through the above technical solution, the dry material enters the kneading machine body 1 through the feed pipe 2, and the binder asphalt is placed in the asphalt mixing mechanism. The asphalt mixing mechanism and the double-headed motor 6 are started by the controller 14. The double-headed motor 6 drives the asphalt spraying mechanism to rotate, so that the asphalt mixing mechanism carries the binder asphalt to the asphalt spraying mechanism. The rotation of the asphalt spraying mechanism sprays the asphalt into the kneading machine body 1, so that the double-headed motor 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the rotating wheel 8 to rotate. The rotating wheel 8 drives the mixing wheel 10 to rotate through the belt 9, so that the mixing wheel 10 drives the mixing rod 11 to rotate, so that the mixing rod 11 mixes the dry material and binder asphalt on the inner wall of the kneading machine body 1. The heating pipe 12 heats the inner wall of the kneading machine body 1 to prevent the binder asphalt from solidifying. After completion, the switch valve 5 is opened to discharge the mixture through the discharge pipe 4, which facilitates uniform spraying of asphalt and improves mixing efficiency and mixing quality.

[0022] like Figure 1-5As shown, the asphalt mixing mechanism includes a mixing drum 31, which is fixedly connected to one side of the surface of the kneading machine body 1. A heating tube 12 is fixedly connected to the inner wall of the mixing drum 31. A servo motor 32 is fixedly connected to one end of the mixing drum 31. A stirring rod 33 is fixedly connected to the output shaft of the servo motor 32. The stirring rod 33 is rotatably connected to the inner wall of the mixing drum 31. A feed inlet is opened at one end of the mixing drum 31. An outlet pipe 34 is fixedly connected to the inner wall of the mixing drum 31. One end of the outlet pipe 34 is located at the bottom wall of the mixing drum 31. An asphalt pump 35 is fixedly connected to one end of the outlet pipe 34. The asphalt pump 35 is fixedly connected to one end of the kneading machine body 1. The controller 14 is electrically connected to the dual-head motor 6, the switch valve 5, the servo motor 32, and the heating tube 12.

[0023] With the above technical solution, the binder asphalt is placed at the inlet of the mixing tank 31. Upon reaching the mixing tank 31, the controller 14 starts the servo motor 32 and the heating tube 12. The servo motor 32 drives the stirring rod 33 to rotate, so that the stirring rod 33 stirs the binder asphalt and prevents the binder asphalt from solidifying. At the same time, the heating tube 12 heats the binder asphalt and starts the asphalt pump 35, so that the asphalt pump 35 drives the outlet pipe 34 to transport the binder asphalt and stir the binder asphalt to prevent the binder asphalt from solidifying.

[0024] The controller 14 is a Mitsubishi FX3U model. This model of controller 14 can control the rotation of the dual-head motor 6 and the servo motor 32 by sending drive pulses. By changing the number of pulses, the amount of movement can be changed, thereby controlling the movement direction of the dual-head motor 6 and the servo motor 32. It can also control the start and stop of the switch valve 5 and the heating tube 12 through digital or analog input / output.

[0025] like Figure 1-5 As shown, the asphalt spraying mechanism includes a gear 21, which is fixedly connected to the output shaft of the dual-head motor 6. A gear ring 22 meshes with the surface of the gear 21. Spray holes 24 are opened on the surface of the gear ring 22. A fixing block 25 is rotatably connected to the inner wall of the gear ring 22. The fixing block 25 is fixedly connected to the inner top wall of the kneading machine body 1. A heating tube 12 is fixedly connected to the inner wall of the fixing block 25. A cover plate 23 is slidably connected to the inner top wall of the gear ring 22. An asphalt pipe 26 is fixedly connected to the inner wall of the cover plate 23. The asphalt pipe 26 is fixedly connected to one end of the kneading machine body 1. One end of the asphalt pipe 26 is fixedly connected to the output end of the asphalt pump 35. The gear 21 is slidably connected to one side of the kneading machine body 1. A sliding groove is opened above the gear ring 22, and the asphalt pipe 26 is slidably connected in the sliding groove.

[0026] Through the above technical solution, the dual-head motor 6 drives the gear 21 to rotate, which in turn drives the gear ring 22 to rotate on the inner wall of the fixed block 25. This causes the asphalt pump 35 to drive the outlet pipe 34 to transport the binder asphalt into the asphalt pipe 26. The asphalt in the asphalt pipe 26 reaches the inner wall of the gear ring 22 and is discharged through the spray hole 24. At the same time, the rotation of the gear ring 22 causes the cover plate 23 and the asphalt pipe 26 to slide in the groove opened above the gear ring 22. The cover plate 23 prevents the asphalt from being exposed, and the gear ring 22 rotates and sprays the binder asphalt. Meanwhile, the heating pipe 12 heats the asphalt, preventing it from sticking together during spraying. This facilitates uniform spraying of the asphalt, improving mixing efficiency and mixing quality.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
