Detailed Implementation

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0029] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0030] This embodiment mainly describes the structure of an asphalt mixture mixer, as detailed below:

[0031] like Figures 1-10 As shown, an asphalt mixture mixer includes a workbench 1 and a support frame 2 mounted on the workbench 1, arranged in an L-shape. The inner side of the top of the support frame 2 is provided with at least two telescopic devices 4, each with its telescopic end facing the workbench 1. A heating seat 3 for heating is provided on the workbench 1 below the telescopic devices 4, and a receiving groove 31 is formed on the heating seat 3. A heating block 32 for heating is embedded in the receiving groove 31 (the heating block 32 is a resistance heating element or an electromagnetic heating element in the prior art, which needs to be connected to a power source during operation). A pot body 6 for holding asphalt mixture is provided in the receiving groove 31, and the top of the pot body 6 is open. A connecting ring 61 is provided on the top of the pot body 6, and the connecting ring 61 is located on the heating seat. At the top of 3, a cover 5 is provided at the telescopic ends of the two telescopic devices 4 to cover the opening of the pot body 6. At the same time, a mixing frame 8 is rotatably provided on the cover 5 to stir the asphalt mixture in the pot body 6. Two support plates 10 are symmetrically provided on the top of the cover 5 between the two telescopic devices 4. A drive motor 7 with its output end detachably connected to the mixing frame 8 is provided on the top of the two support plates 10. Thus, the drive motor 7 can control the rotation of the mixing frame 8. In order to ensure the stability of the drive motor 7 on the support plate 10, a fixing frame 9 is provided on the drive motor 7, which is detachably connected to the two support plates 10 by bolts at its left and right ends. The drive motor 7 is a variable frequency motor or servo motor that can adjust the speed in the prior art.

[0032] Thus, when the asphalt mixture mixer is working, the telescopic device 4 is first in a shortened state, so that the cover 5 and the mixing frame 8 installed on the cover 5 are away from the heating seat 3 and the top of the pot 6. Then, the raw materials for preparing asphalt mixture (such as asphalt, coarse aggregate, fine aggregate, mineral powder, etc.) are added to the pot 6. Then, the heating seat 3 is activated to heat the raw materials in the pot 6. At the same time, the telescopic device 4 is activated to extend its telescopic end, so that the cover 5 can cover the top of the pot 6. The drive motor 7 is started, so that when the drive motor 7 starts, the mixing frame 8 connected to the output end of the drive motor 7 can rotate in the pot body 6, thus realizing the preparation of asphalt mixture. At the same time, the preparation of asphalt mixture can be completed by the cooperation of the worktable 1, support frame 2, telescopic device 4, heating seat 3, pot body 6, drive motor 7, cover 5 and mixing frame 8, thereby simplifying the structure of the asphalt mixture mixer, reducing the overall weight of the asphalt mixture mixer, and making it easier for users to move the asphalt mixture mixer.

[0033] When the asphalt mixture is finished, the telescopic device 4 is activated again to shorten the telescopic end. This allows the cover 5 installed on the telescopic end of the telescopic device 4 to move away from the top of the heating base 3, so that the cover 5 no longer covers the pot body 6. Then, the staff can remove the pot body 6 from the receiving groove 31 in the heating base 3. This makes it easier for the staff to remove the asphalt mixture from the pot body 6, and also makes it easier for the staff to clean the pot body 6. If the pot body 6 is damaged, it is also easier for the staff to replace it. At the same time, when the drive motor 7 is damaged, the bolts used to fix the fixing frame 9 are first removed from the fixing frame 9, so that the fixing frame 9 is no longer connected to the support plate 10. This allows the staff to remove the fixing frame 9 from the drive motor 7, and then remove the drive motor 7 from the support plate 10 for replacement or repair. This makes it easier for the user to maintain the asphalt mixture mixer.

[0034] Furthermore, to ensure the stability of the pot body 6 in the receiving groove 31 when the stirring rack 8 rotates, at least two fixing posts 33 are provided on the top of the heating base 3. At the same time, a connecting hole 611 matching the fixing posts 33 is opened at the bottom of the connecting ring 61. When the pot body 6 is placed in the receiving groove 31, the fixing posts 33 are inserted into the connecting hole 611. In this way, the setting of the fixing posts 33 can prevent the pot body 6 from rotating in the receiving groove 31, thereby ensuring the stability of the pot body 6 in the receiving groove 31 when the stirring rack 8 rotates.

[0035] Furthermore, in order to ensure the sealing performance when the cover 5 is connected to the pot body 6, a sealing ring 62 protruding from the top of the connecting ring 61 is provided, and a sealing groove 51 matching the sealing ring 62 is provided at the bottom of the cover 5. This ensures the heat preservation effect of the pot body 6 when the asphalt mixture mixer is working. (The sealing ring 62 is made of high temperature resistant material, such as polytetrafluoroethylene sealing ring 62.)

[0036] Furthermore, in order to facilitate the connection between the drive motor 7 and the stirring rack 8, a first connecting post 71 is provided at the output end of the drive motor 7, and a polygonal connecting groove 711 is provided at the bottom of the first connecting post 71. Then, a second connecting post 81 that matches the connecting groove 711 is provided at the top of the stirring rack 8.

[0037] Furthermore, to facilitate the assembly and disassembly of the support frame 2, the support frame 2 is detachably connected to the workbench 1 via bolts.

[0038] Furthermore, to facilitate placing the pot body 6 into or removing it from the receiving groove 31, a screw moving mechanism 11 connected to the heating seat 3 is provided on the workbench 1. The screw moving mechanism 11 is used to control the movement of the heating seat 3 on the workbench 1, so that when the screw moving mechanism 11 is working, it can control the heating seat 3 to move away from the bottom of the stirring rack 8, thereby facilitating the workers to place the pot body 6 into or remove it from the receiving groove 31. (The screw moving mechanism 11 is a mature existing technology, and the screw moving mechanism 11 includes a moving groove 1103, a screw 1102, a moving block 1104, and a driving device 1101).

[0039] Furthermore, to ensure the reliability of the connection between the pot body 6 and the connecting ring 61, the pot body 6 and the connecting ring 61 are integrally formed.

[0040] Furthermore, in order to prevent the top of the drive motor 7 from being crushed by the fixing frame 9, an elastic block 91 is provided on the inner side of the top of the fixing frame 9 to abut against the housing of the drive motor 7, and the elastic block 91 is made of rubber.

[0041] Furthermore, to facilitate the handling of the pot body 6 by staff, two handles 12 are symmetrically arranged on the side wall of the connecting ring 61. To prevent staff from being burned by the handles 12, each handle 12 is fitted with a heat-insulating sleeve 121 made of heat-insulating material (such as silicone rubber). In the description of this utility model, it should be noted that the terms "upper," "lower," "front," "rear," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. These terms are used only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
