Description

Technical Field

[0001] This utility model relates to the field of asphalt mixing, specifically an asphalt mixing device for asphalt pavement maintenance vehicles. Background Technology

[0002] Asphalt is a complex mixture composed of hydrocarbons and their non-metallic derivatives. It is mainly composed of hydrocarbons of different molecular weights (such as alkanes and cyclic hydrocarbons) and non-metallic derivatives (such as sulfur compounds and nitrogen compounds), appearing as a dark brown or viscous substance. Asphalt is required for road paving, and this process necessitates the use of asphalt pavement maintenance vehicles equipped with mixing devices. The "Asphalt Mixing Device for Asphalt Pavement Maintenance Vehicles" disclosed in application number "202121443199.7" represents an increasingly mature technology. This device, through a drive mechanism, uses a drive motor to rotate two half-gears via a rotating shaft. Because the teeth of the two half-gears face opposite directions, they contact the connecting column during rotation, causing the turntable to rotate back and forth. Compared to traditional mixing, this technology only utilizes small-amplitude mixing to ensure the asphalt remains within the tank. The device features slight movement to prevent asphalt from sticking together, and because the mixing is not vigorous, heat loss is minimal. This combination of structures solves the problem of asphalt hardening easily during long transport times in existing maintenance vehicles. However, this mixing device still has the following drawbacks: While it mixes asphalt by using a drive motor to rotate the shaft and half-gear, the mixing effect is not significant enough, making it difficult to perform omnidirectional mixing without dead angles, thus affecting the mixing quality. Therefore, it is necessary to provide a mixing device that facilitates omnidirectional mixing of asphalt and improves mixing quality. Furthermore, this mixing device only mixes asphalt and is not suitable for crushing large particles in the asphalt, thus affecting the asphalt's performance. Therefore, it is necessary to provide a mixing device that facilitates the crushing of large particles in asphalt and enhances its performance. Utility Model Content

[0003] This utility model provides an asphalt mixing device for asphalt pavement maintenance vehicles, aiming to solve the problems of existing mixing devices being inconvenient for all-round mixing of asphalt and for crushing large internal particles.

[0004] To achieve the above objectives, this utility model provides an asphalt mixing device for asphalt pavement maintenance vehicles, including a mixing component and a crushing component;

[0005] The stirring assembly includes a base, with two first transmission gears rotatably connected to both sides of the upper end of the base. A first motor is installed on one side of one of the first transmission gears. A stirring tank is rotatably connected to the upper end of the base. Two gear grooves are formed on the surface of the stirring tank, and the two first transmission gears are meshed inside the gear grooves.

[0006] The pulverizing assembly includes a first rotating shaft and a second rotating shaft installed inside a mixing tank. The side surfaces of the first rotating shaft and the second rotating shaft are each provided with a plurality of pulverizing teeth at equal intervals. A transmission mechanism is installed at one end of the second rotating shaft.

[0007] In a preferred embodiment of the present invention, the transmission mechanism includes a first transmission disc mounted on one end of a second rotating shaft, a second motor mounted on the upper end of the base, the output end of the second motor connected to the second transmission disc, and a transmission belt connecting the first transmission disc and the second transmission disc.

[0008] As a preferred embodiment of this utility model, the upper end of the base is fixedly connected to several supports, and several first transmission gears are rotatably connected inside the supports.

[0009] As a preferred embodiment of this utility model, the surface of the base is provided with a plurality of insertion holes, and each of the plurality of insertion holes is provided with an insertion rod, the lower end of which is fixedly connected to a conical seat.

[0010] As a preferred embodiment of this utility model, both ends of the mixing tank are rotatably connected to end caps, and the inner wall of the mixing tank is equipped with a plurality of mixing plates arranged in an array at equal intervals.

[0011] As a preferred embodiment of this utility model, a second transmission gear is installed at one end of both the first rotating shaft and the second rotating shaft, and the two second transmission gears are meshed together.

[0012] In a preferred embodiment of this utility model, the first rotating shaft, the second rotating shaft, and the crushing teeth are all made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When performing all-round mixing of asphalt, the asphalt is first injected into the mixing tank. Then, the first motor is started to drive one of the first transmission gears to rotate. At this time, several first transmission gears are meshed and connected in the gear groove. The rotation of one of the first transmission gears can control the rotation of the mixing tank, thereby enabling the asphalt inside to rotate in all directions. With the help of the mixing plate in the mixing tank, the asphalt can be mixed in all directions without dead angles. Compared with the mixing device in the existing technology "Asphalt mixing device for asphalt road maintenance vehicle", this utility model can facilitate all-round mixing of asphalt through the above-mentioned structure, thereby improving the mixing quality of asphalt.

[0015] 2. When crushing large particles in asphalt, the transmission mechanism is first activated to rotate the second shaft, which in turn rotates the second transmission gear at one end of the second shaft. This, in turn, drives the first transmission gear to rotate. The meshing of the first and second transmission gears allows the first and second shafts to rotate relative to each other. At this point, the staggered crushing teeth can crush the large particles in the asphalt. Compared to the existing mixing device in the "Asphalt Mixing Device for Asphalt Road Maintenance Vehicle," this invention, through the aforementioned structural cooperation, facilitates the mixing of large particles in asphalt, thereby improving the performance of the asphalt.

[0022] Example 1

[0023] Please see Figures 1-4 This utility model provides an asphalt mixing device for asphalt pavement maintenance vehicles, including a mixing component 100 and a crushing component 200;

[0024] The stirring assembly 100 includes a base 101, with two first transmission gears 102 rotatably connected to both sides of the upper end of the base 101.

Two gear grooves 105 are formed on the surface of the stirring tank 104, and the two first transmission gears 102 are meshed and connected inside the gear grooves 105.

[0025] The crushing component 200 includes a first rotating shaft 201 and a second rotating shaft 202 installed inside the mixing tank 104. The side surfaces of the first rotating shaft 201 and the second rotating shaft 202 are provided with a plurality of crushing teeth 203 at equal intervals. A transmission mechanism 204 is installed at one end of the second rotating shaft 202.

[0026] In one specific embodiment, the mixing component 100, in conjunction with the crushing component 200, not only facilitates all-round, dead-angle-free mixing of asphalt, thereby improving the mixing quality of the asphalt, but also, through the cooperation of the above structures, can crush large particles in the asphalt, ensuring the effectiveness of the asphalt and enhancing the practicality of the mixing device. In use, asphalt is first injected into the mixing tank 104. Then, the transmission mechanism 204 is activated, rotating the second shaft 202. The second transmission gear 211 controls the relative rotation of the first shaft 201 and the second shaft 202. The crushing teeth 203, interleaved on the side surfaces of the first shaft 201 and the second shaft 202, crush large particles in the asphalt. After crushing the asphalt, the first motor 103 is activated, rotating one of the first transmission gears 102. The first transmission gear 102 is meshed inside the gear groove 105, thus rotating the mixing tank 104, enabling all-round, dead-angle-free mixing of the asphalt inside, improving the mixing quality and enhancing the practicality of the mixing device.

[0027] Please see Figure 2 and Figure 3The transmission mechanism 204 includes a first transmission disc 2041 installed at one end of the second rotating shaft 202, a second motor 2042 installed at the upper end of the base 101, a second transmission disc 2043 connected to the output end of the second motor 2042, and a transmission belt 2044 connected between the first transmission disc 2041 and the second transmission disc 2043.

[0028] In one specific embodiment, the second motor 2042 drives the second transmission disk 2043 to rotate, and the transmission belt 2044 can drive the first transmission disk 2041 and the second rotating shaft 202 on its surface to rotate, thus achieving a transmission effect.

[0029] Please see Figure 2 and Figure 3 The upper end of the base 101 is fixedly connected to several supports 111, and several first transmission gears 102 are rotatably connected inside the supports 111.

[0030] In one specific embodiment, the support 111 can enhance the rotational connection stability of the first transmission gear 102 and improve the erection stability of the mixing tank 104.

[0031] Please see Figure 2 and Figure 3 The surface of the base 101 is provided with several insertion holes 121, and each insertion hole 121 is fitted with an insertion rod 122. The lower end of the insertion rod 122 is fixedly connected to a conical seat 123.

[0032] In one specific embodiment, the plug rod 122 is inserted into the plug hole 121, and the conical seat 123 can increase the stability of the base 101 installed on the road maintenance vehicle and improve the safety of the mixing device.

[0033] Please see Figure 2 and Figure 3 Both ends of the mixing tank 104 are rotatably connected to end caps 131, and several mixing plates 132 are installed in an array at equal intervals on the inner wall of the mixing tank 104.

[0034] In one specific embodiment, the end cap 131 and the mixing tank 104 are rotatably connected, so that when the mixing tank 104 rotates, the crushing component 200 can maintain an angle.

[0035] Please see Figure 4 A second transmission gear 211 is installed at one end of the first rotating shaft 201 and the second rotating shaft 202, and the two second transmission gears 211 are meshed together.

[0036] In one specific embodiment, two second transmission gears 211 are meshed together. When the second rotating shaft 202 rotates, the two second transmission gears 211 can rotate the first rotating shaft 201 to facilitate the crushing of large particles in the asphalt.

[0037] Please see Figure 4 The first rotating shaft 201, the second rotating shaft 202, and the crushing tooth 203 are all made of stainless steel.

[0038] In one specific embodiment, the first rotating shaft 201, the second rotating shaft 202, and the crushing teeth 203, all made of stainless steel, can ensure their own strength and avoid rust and corrosion, thus extending their service life.

[0039] Working principle: In use, asphalt is first injected into the mixing tank 104, and then the transmission mechanism 204 is started to rotate the second rotating shaft 202. With the cooperation of the second transmission gear 211, the relative rotation of the first rotating shaft 201 and the second rotating shaft 202 can be controlled. The crushing teeth 203, which are staggered on the side surfaces of the first rotating shaft 201 and the second rotating shaft 202, can crush large particles in the asphalt. After crushing the asphalt, the first motor 103 is started to rotate one of the first transmission gears 102. The first transmission gear 102 is meshed and connected inside the gear groove 105, which can rotate the mixing tank 104, thereby enabling all-round and dead-angle mixing of the asphalt inside, thus improving the mixing quality of the asphalt and enhancing the practicality of the mixing device.
