DETAILED DESCRIPTION

[0028] The present application is further described below in conjunction with specific embodiments and drawings.

[0029] Example 1

[0030] refer to Figure 1 to Figure 5 As shown, an asphalt mixture storage hopper includes a hopper body 1, stirring blades 3, a conveying mechanism 4, a fixing mechanism 5, a baffle 6, a stirring drive mechanism and a conveying drive mechanism.

[0031] The hopper body 1 is a rectangular parallelepiped structure with an upper feed port to allow asphalt to fall in from above. The outer and inner sides of the hopper body 1 are a mixing area and a discharge port, respectively, that is, the hopper body 1 is surrounded on three sides, and only the inner side is open for discharge.

[0032] The bottom of the hopper body 1 is provided with a conveying mechanism 4 located between the stirring place and the discharge port, and the conveying mechanism 4 conveys the asphalt material and pushes the material in the hopper out continuously. The conveying mechanism 4 is connected to the conveying drive mechanism, and the conveying drive mechanism provides power for the conveying mechanism 4.

[0033] The hopper body 1 is provided with a stirring blade 3 which is arranged to rotate at the stirring position. The stirring blade 3 is located above the conveying mechanism 4. The stirring blade 3 stirs and mixes the asphalt in the hopper, and the rotating stirring blade has the function of pushing the asphalt. The stirring blade 3 is connected to the stirring drive mechanism, and the stirring drive mechanism provides power for the rotation of the blade.

[0034] A fixing mechanism 5 is provided inside the conveying mechanism 4, and the fixing mechanism 5 has the function of supporting and / or heating the conveying mechanism 4. Firstly, the fixing mechanism 5 supports the conveying mechanism 4 to ensure that its conveying belt 42 does not bend or deform under pressure, and secondly, the fixing mechanism 5 heats the conveying belt 42 and then transfers the heat to the asphalt to prevent condensation and accumulation of materials.

[0035] The stirring blades 3 and the conveying mechanism 4 are arranged along the entire length of the hopper body 1, that is, arranged across both ends of the hopper body 1, to ensure that the stirring and conveying functions can cover the entire hopper. The stirring blades 3 are used to stir the asphalt, and the conveying mechanism 4 cooperates with the stirring work of the stirring blades 3 at the top thereof to achieve the effect of controlling the asphalt accumulated inside the hopper body 1 to be thoroughly conveyed and dropped.

[0036] The stirring blade 3 is a shaft body with radial blades, the blades directly act on the asphalt, and the shaft body is rotatably arranged on the hopper body 1 through a bearing.

[0037] The conveying mechanism 4 includes a rotating roller 41 and a conveyor belt 42. The rotating roller 41 is arranged to rotate on the hopper body 1 through a bearing. The two rotating rollers 41 are respectively arranged at the stirring point and the discharge port of the hopper body 1. The conveyor belt 42 is wound between the two rotating rollers 41. The conveyor belt 42 is a complete circulation belt that directly acts on the asphalt to push it outward.

[0038] The conveying drive mechanism will drive the rotating roller 41 coaxially connected to its top to rotate. When the rotating roller 41 rotates, the conveyor belt 42 outside it will rotate, thereby transporting the asphalt accumulated on the conveyor belt 42, and finally discharge it at the top of the hopper body 1 to the top of the scraper conveyor for transportation.

[0039] The stirring drive mechanism and the conveying drive mechanism are the same linkage mechanism 2, that is, the stirring and conveying functions are driven by the same mechanism. The linkage mechanism 2 is arranged outside the hopper body 1 and includes a driving motor 21, a driving disk 22, a conveyor belt 23 and a driven disk 24.

[0040] The driving motor 21 is fixedly arranged on the hopper body 1, and the driving motor 21 is fixedly connected to the active disk 22, and the active disk 22 is transmission-connected to the driven disk 24 through the conveyor belt 23. One of the active disk 22 and the driven disk 24 is connected to the stirring blade 3, and the other is connected to the conveying mechanism 4. Specifically, the active disk 22 is fixedly connected to the rotating roller 41 at the discharge port through the shaft penetrating the hopper body 1 and the fixed rod 54, and the driven disk 24 is fixedly connected to the stirring blade 3 through the shaft penetrating the hopper body 1.

[0041] When the linkage mechanism 2 is working, it is necessary to start the driving motor 21 at its top, so that it drives the active disk 22 at its top to rotate, and then the driven disk 24 is rotated under the action of the conveyor belt 23. Therefore, the active disk 22 rotates to drive the conveying mechanism 4 to work and complete the conveying work. The driven disk 24 rotates to drive the stirring blade 3 coaxially connected to its top to rotate, completing the stirring and dredging work of the asphalt.

[0042] The fixing mechanism 5 includes a placing frame 51, a cover plate 52, a heating wire 53, a fixing rod 54 and a buckle 55. The placing frame 51 and the fixing rod 54 are both located in the conveyor belt 42 of the conveying mechanism 4, the placing frame 51 is located in the middle, and two fixing rods 54 are symmetrically fixed at both ends of the placing frame 51. The fixing rods 54 are fixed on the hopper body 1 to support the conveyor belt 42 and prevent the conveyor belt from bending under pressure. The bearing of the rotating roller 41 can also be arranged on the fixing rod 54.

[0043] The placement frame 51 is a rectangular box with an upper opening. A heating wire 53 is arranged inside the placement frame 51, and the conveyor belt 42 and the like are heated by the heating wire 53. This ensures that the asphalt is heated when it is transported, and that the phenomenon of rapid cooling, solidification and accumulation does not occur. The upper opening of the placement frame 51 is tightly matched with the buckle 55 of the cover plate 52, and the placement frame 51 is closed by the cover plate 52, so that the subsequent maintenance and installation of the heating wire 53 is also convenient.

[0044] A baffle 6 is provided at the mixing part of the hopper body 1. The baffle 6 is located between the stirring blade 3 and the conveying mechanism 4. The baffle 6 blocks the gap between the hopper body 1 and the conveying mechanism 4. The baffle 6 guides the asphalt material acted on by the stirring blade 3 to prevent it from entering the gap and blocking the belt. The setting of the baffle 6 can ensure that the asphalt falling into the hopper body 1 will not accumulate in the gap between the conveying mechanism 4 and the hopper body 1. In combination with the rotation of the stirring blade 3 at the top of the conveying mechanism 4, it can ensure that the conveying mechanism 4 can carry out continuous asphalt conveying work when conveying.

[0045] Example 2

[0046] refer to Figure 1 to Figure 6As shown, an asphalt pavement storage and transportation device includes a scraper conveyor 7 and an asphalt mixture storage hopper of Example 1, two hopper bodies 1 are respectively located on both sides of the scraper conveyor 7, and the discharge port of the hopper body 1 is located above the scraper conveyor 7. The hopper body 1 is used for storing and dropping asphalt, and the scraper conveyor 7 is used for further transporting asphalt to the pavement.

[0047] The workflow of this application:

[0048] When in use, first, an external asphalt storage vehicle pours the asphalt into the interior of the hopper body 1. Then, in order to ensure that the asphalt inside the hopper body 1 is completely transported to the scraper conveyor in the middle, it is necessary to start the linkage mechanism 2, so that the linkage mechanism 2 drives the conveying mechanism 4 at its top to start. At this time, the conveying mechanism 4 will transport the asphalt accumulated inside the hopper body 1 to the position of the scraper conveyor. When the conveying mechanism 4 is working, the stirring blades 3 at its top also continuously rotate and stir, thereby ensuring that it can stir and dredge the asphalt accumulated on the top of the conveying mechanism 4, ensuring that the asphalt will not accumulate inside the hopper body 1, thereby allowing the conveying mechanism 4 to completely transport the asphalt.

[0049] The aforementioned basic examples and their further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection in this application. In the scheme of this application, each selected example can be arbitrarily combined with any other basic examples and selected examples.
