Description

Technical Field

[0001] This utility model relates to the technical field of asphalt mixing equipment, specifically an intermittent asphalt mixture mixing device. Background Technology

[0002] Asphalt mixture is a composite material mainly composed of asphalt, coarse aggregate, fine aggregate, and mineral powder, and some also contain polymers and wood cellulose. These materials of different qualities and quantities are mixed to form different structures and have different mechanical properties. In the process of using asphalt, the asphalt mixture needs to be mixed, which usually requires pre-stirring. However, existing mixing equipment has the following drawbacks in use; First, existing mixing structures mostly use a mixing rod for unidirectional mixing, which can meet basic mixing requirements, but the mixing effect is not good for asphalt mixtures containing multiple materials; Secondly, existing mixing equipment often adds the material directly into the tank. A large amount of material not only easily leads to uneven mixing, but also increases the burden on the equipment. Therefore, an intermittent asphalt mixture mixing device is proposed.

This device drives the central shaft and transmission sleeve to run in opposite directions through a meshing transmission assembly. On the one hand, the staggered first and second mixing components can generate a "shearing" effect to achieve a fast, efficient and thorough mixing process of the asphalt mixture. On the other hand, the intermittent feed valve assembly can realize the intermittent feeding operation of the feed bin, thereby ensuring the uniformity of the asphalt mixture mixing inside the mixing tank.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an intermittent asphalt mixture mixing device, comprising: a feed hopper, a mixing tank, and a tank support assembled sequentially from top to bottom; a central shaft and a transmission sleeve disposed at the bottom of the mixing tank and distributed inside and outside, wherein the central shaft and the transmission sleeve both extend into the interior of the mixing tank and are staggeredly arranged with a first mixing component and a second mixing component; and an intermittent feed valve assembly disposed at the top of the central shaft and built into the feed hopper for intermittent controlled feeding of asphalt; further comprising a meshing transmission component disposed within the tank support and drivenly connected to the bottom end of the central shaft and the transmission sleeve, wherein when the meshing transmission component is running, the central shaft and the transmission sleeve run in opposite directions to achieve efficient mixing of the first mixing component and the second mixing component.

Detailed Implementation

[0014] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0015] Example 1 Please see Figures 1 to 6The present invention preferably provides the following technical solution: an intermittent asphalt mixture mixing device, comprising: a feeding hopper, a mixing tank 111, and a tank support 114 assembled sequentially from top to bottom; a central shaft 112 and a transmission sleeve 113 disposed at the bottom of the mixing tank 111 and distributed inside and outside, wherein the central shaft 112 and the transmission sleeve 113 both extend into the interior of the mixing tank 111 and are staggeredly arranged with a first mixing component and a second mixing component; and an intermittent feeding valve assembly disposed at the top of the central shaft 112 and built into the feeding hopper for intermittent controlled feeding of asphalt; and a meshing transmission component disposed inside the tank support 114 and drivenly connected to the bottom end of the central shaft 112 and the transmission sleeve 113, wherein when the meshing transmission component is running, the central shaft 112 and the transmission sleeve 113 run in opposite directions to achieve efficient mixing of the first mixing component and the second mixing component.

[0016] Furthermore, the transmission sleeve 113 is limited and installed inside the limiting hole opened at the bottom of the 111, and the central shaft 112 is disposed inside the transmission sleeve 113 and is rotatably installed with it for limiting. In this embodiment, as shown... Figure 1 , 2 As shown, the top of the mixing tank 111 is connected to the feed hopper, and its bottom is mounted on the tank support 114. A central shaft 112 and a transmission sleeve 113, located inside and outside the bottom of the mixing tank 111, extend one end into the tank and are respectively provided with a first mixing assembly and a second mixing assembly arranged in a staggered pattern. Simultaneously, the top of the central shaft 112 extends into the feed hopper and contains an intermittent feed valve assembly. Figure 3 , 5 As shown in Figure 6, the central shaft 112 and the bottom of the transmission sleeve 113 are driven in opposite directions through the meshing transmission assembly. Therefore, when the meshing transmission assembly is working, it drives the first and second mixing assemblies to run in opposite directions. At this time, the staggered first and second mixing assemblies can generate a "shearing" effect to achieve a fast, efficient and thorough mixing process of the asphalt mixture. On the other hand, it drives the intermittent feed valve assembly to rotate, so as to realize the intermittent and controlled feeding operation of the feed bin, thereby ensuring the uniformity of the asphalt mixture mixing inside the mixing tank 111.

[0017] Example 2 In another embodiment of this utility model, the feeding hopper includes a feeding mask 311 and a mounting assembly 312 fixed to the top of the mixing tank 111 and distributed vertically. The feeding mask 311 has a partition 3111 that divides it into front and rear cavities. The mounting assembly 312 has two first feeding ports 313 and two second feeding ports 314 staggered on its upper and lower surfaces. The two first feeding ports 313 are connected to the front and rear cavities of the feeding mask 311, and the two second feeding ports 314 are used to connect the mounting assembly 312 with the mixing tank 111. Further, the intermittent feeding valve assembly includes two transfer frames 315 fixed to the top of the central shaft 112 and extending into the mounting assembly 312. When the two transfer frames 315 are connected to the two first feeding ports 313, they are used for feeding the two transfer frames 315. When the two transfer frames 315 are connected to the two second feeding ports 314, they are used for feeding the mixing tank 111.

[0018] This implementation is an example Figure 3 , 4 As shown in Figure 6, it is known that the two first feed ports 313 on the upper surface of the assembly 312 are connected to the front and rear cavities of the inlet mask 311, while the two second feed ports 314 on its lower surface are used to connect the assembly 312 to the mixing tank 111. At the same time, the two first feed ports 313 and the two second feed ports 314 are staggered. When the two transfer frames 315 fixed at the top of the central shaft 112 rotate through the meshing transmission assembly, if they are connected to the inlet mask 311, they can feed themselves. When they are connected to the mixing tank 111, the asphalt mixture inside can enter the mixing tank 111. This design can achieve intermittent controlled feeding of the mixing tank 111 by intermittently transferring a fixed amount of asphalt mixture through the transfer frames 315.

[0019] Example 3 In another embodiment of the present invention, the first stirring assembly includes a disc-shaped stirring element 316 fixed on the upper part of the central shaft 112 and built into the stirring tank 111, and the diameter of the disc-shaped stirring element 316 increases sequentially from top to bottom; and a plurality of first stirring rods 317 annularly fixed on the lower part of the central shaft 112; further, the second stirring assembly includes a mounting ring fixed on the top end of the transmission sleeve 113; brackets 318 annularly distributed on the mounting ring; and second stirring rods 319 longitudinally fixed inside each bracket 318 and staggered from the plurality of first stirring rods 317.

[0020] In this embodiment, such as Figure 5As shown, a disc-shaped stirring element 316 and several sets of first stirring rods 317 are fixed to the upper and lower parts of the central shaft 112, respectively. Several sets of second stirring rods 319 fixed on the transmission sleeve 113 can correspond one-to-one with several sets of first stirring rods 317. Each set of several second stirring rods 319 and several sets of first stirring rods 317 are staggered. When the meshing transmission assembly drives the central shaft 112 and the transmission sleeve 113 to run in opposite directions, the first stirring rods 317 and the second stirring rods 319 run relative to each other and generate a "shearing" effect to improve the mixing effect.

[0021] Example 4 In another embodiment of this utility model, the meshing transmission assembly includes a first transmission gear 411 and a second transmission gear 412 respectively fixed to the bottom of the central shaft 112 and the transmission sleeve 113; and a first mounting plate 413 fixed to the inner wall of the tank support 114. A motor 414 is provided at the bottom of the first mounting plate 413, wherein the output axis of the motor 414 passes through a through hole opened on the first mounting plate 413 and a drive gear 415 is fixed thereon, and the drive gear 415 meshes with the first transmission gear 411; a second mounting plate fixed to the inner wall of the tank support 114; and a third gear 416 disposed on the second mounting plate, wherein the third gear 416 is positioned between the drive gear 415 and the second transmission gear 412 and meshes with them.

[0022] like Figure 3 , 5 As shown, the first transmission gear 411 and the second transmission gear 412 are fixed to the bottom ends of the central shaft 112 and the transmission sleeve 113, respectively. The drive gear 415 directly meshes with the first transmission gear 411 and indirectly rotates with the second transmission gear 412 through the third gear 416. Therefore, when the drive gear 415 rotates through the motor 414, the first transmission gear 411 and the first mounting plate 413 can rotate in opposite directions and synchronously, thereby realizing the opposite operation process of the central shaft 112 and the transmission sleeve 113.

[0023] Example 5 As another embodiment of the present invention, a discharge chamber is provided on the side of the bottom of the mixing tank 111 away from the meshing transmission assembly. The discharge chamber includes a discharge port 512 opened at the bottom of the mixing tank 111, a guide plate 511 fixed to the inner side of the discharge port 512, and a pull rail provided at the bottom of the mixing tank 111. A pull plate 513 is provided in the pull rail for controlling the opening and closing of the discharge port 512.

[0024] like Figure 2 , 6 As shown, the discharge hopper is located at the discharge port 512 at the bottom of the mixing tank 111. A guide plate 511 is fixed inside the discharge hopper, and a pull plate 513 is installed between them via a pull rail. Therefore, when discharge is required, the pull plate 513 can be operated.

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.
