[0030] In order to enable those skilled in the art to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. Based on the embodiments in this utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this utility model.

[0031] As recorded in the background art, traditional asphalt mixture stirrers usually adopt a fixed stirring blade design. Although this design can complete the basic stirring tasks during long-term and high-intensity stirring operations, it shows obvious limitations in many aspects; from the perspective of transportation and storage, the design of fixed blades results in a large overall volume of the stirrer, which not only occupies a large amount of transportation space and increases transportation costs, but also during long-distance transportation or frequent movement, the blade part is extremely vulnerable to bumps and damages from the external environment, thus affecting the stirring effect and service life.

[0032] To solve this technical problem, this utility model provides an asphalt mixture stirrer.

[0033] Specifically, please refer to Figures 1 - 3 , the asphalt mixture agitator specifically includes:

[0034] A support plate 1, on which a support pipe 3 is installed through a bearing. The middle of the support pipe 3 is connected to a rotating shaft 301 through a bearing. A plurality of first blades 302 are arranged on the outer surface of the rotating shaft 301. Both sides of the bottom of the support pipe 3 are fixedly connected with support frames 303, and a plurality of third blades 305 are fixedly installed on the inner side surface of the support frames 303.

[0035] The asphalt mixture agitator provided by the present utility model is composed of two groups of blades, namely the first blades 302 and the third blades 305. The two groups of blades can rotate relative to each other. In the stirring working state, the first blades 302 and the third blades 305 are vertically arranged, forming multiple stirring paths, which significantly improves the stirring efficiency and mixing uniformity; in the non-working state or during transportation, the first blades 302 and the third blades 305 rotate to the coplanar state, greatly reducing the overall volume of the agitator, thereby greatly facilitating the carrying and storage of the equipment, reducing the transportation cost. At the same time, the blades in the parallel state can also effectively reduce the damage caused by external bumps, and extend the service life of the agitator.

[0036] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0039] Example 1, please refer to Figures 1 - 3, an asphalt mixture mixer, comprising a support plate 1. A support pipe 3 is installed on the support plate 1 through bearings. The middle part of the support pipe 3 is connected to a rotating shaft 301 through a bearing. A plurality of first blades 302 are arranged on the outer surface of the rotating shaft 301. Both sides of the bottom of the support pipe 3 are fixedly connected with support frames 303. A plurality of third blades 305 are fixedly installed on the inner side surface of the support frames 303. This application consists of two groups of blades, namely the first blades 302 and the third blades 305. The two groups of blades can rotate relative to each other. In the mixing working state, the first blades 302 and the third blades 305 are vertically arranged, forming multiple mixing paths, significantly improving the mixing efficiency and mixing uniformity; in the non-working state or during transportation, the first blades 302 and the third blades 305 rotate to the same plane state, greatly reducing the overall volume of the mixer, thus greatly facilitating the carrying and storage of the equipment, reducing the transportation cost. At the same time, the blades in the parallel state can also effectively reduce the damage caused by external bumps to it, extending the service life of the mixer.

[0040] Further, as Figure 2 and Figure 3 shown, a plurality of second blades 304 are fixedly installed on the outer side surface of the support frame 303. The second blades 304 and the third blades 305 are respectively located on both sides of the support frame 303. The arrangement of the second blades 304 can improve the mixing effect.

[0041] Further, as Figure 2 and Figure 3 shown, the bottom end of the rotating shaft 301 is installed with a support seat 306 through a bearing. The support seat 306 is fixedly connected with the support frame 303. The support seat 306 can connect the rotating shaft 301 and the support frame 303 together to improve the overall stability.

[0042] Example 2 further optimizes the asphalt mixture mixer provided in Example 1. Specifically, as Figures 1 - 3 shown, a protective cover 5 is arranged on the top of the support plate 1, and a driving mechanism 2 is arranged inside the protective cover 5. The driving mechanism 2 is connected to the rotating shaft 301 and the support pipe 3. The protective cover 5 can protect the driving mechanism 2.

[0043] Further, as Figure 2 and Figure 3As shown, the driving mechanism 2 includes a driving motor 201 installed on the top of the support plate 1. The output shaft of the driving motor 201 is connected with a first bevel gear 202. The first bevel gear 202 meshes with a second bevel gear 204 and a third bevel gear 205. The second bevel gear 204 and the third bevel gear 205 are respectively fixedly connected with the rotating shaft 301 and the support pipe 3. Such a setting enables the support frame 303 and the rotating shaft 301 to rotate in opposite directions, and further enables the stirring directions of the first blade 302 and the third blade 305 to be opposite, so as to improve the stirring uniformity.

[0044] Embodiment 3 further optimizes the asphalt mixture stirrer provided in Embodiment 1 or 2. Specifically, as Figures 1 - 3 shown, a protective support mechanism 4 is arranged at the bottom of the support plate 1. The protective support mechanism 4 is used for protecting the first blade 302 and the third blade 305, and is also used for protecting the second blade 304, reducing the damage of the first blade 302, the third blade 305 and the second blade 304.

[0045] Furthermore, as Figure 1 and Figure 2 shown, the protective support mechanism 4 includes two protective members. Both protective members are installed at the bottom of the support plate 1, and the first blade 302 and the third blade 305 are located between the two protective members. The two protective members can cooperate with each other to protect the first blade 302, the third blade 305 and the second blade 304, and during stirring, the two protective members can be unfolded to support above the material bucket to support the support plate 1.

[0046] Furthermore, as Figure 2 shown, the protective member includes two first connection seats 401 fixedly installed at the bottom of the support plate 1. A damping rotating shaft is arranged between the two first connection seats 401, and the damping rotating shaft is connected with a second connection seat 402. The second connection seat 402 is fixedly connected with a protective shell 403. The protective shell 403 and the support plate 1 can be connected together through the cooperation of the first connection seat 401, the second connection seat 402 and the damping rotating shaft.

[0047] Furthermore, as Figure 2 shown, sliding grooves 404 are formed on both sides of the protective shell 403. Fixed bolts 407 are slidably connected in the two sliding grooves 404. A clamping plate 405 is threadedly connected between the two fixed bolts 407. Loosening the fixed bolts 407 can fix the position of the clamping plate 405, and the fixed bolts 407 can improve the protection effect on the first blade 302, the third blade 305 and the second blade 304.

[0048] Furthermore, as Figure 2 and Figure 3As shown, one side of the clamping plate 405 is fixedly connected with a rubber pad 406. The rubber pad 406 can prevent the clamping plate 405 from contacting the support base 306 and the support frame 303, further improving the protection effect. The clamping plates 405 in the two protective members are arranged one above the other. Refer to Figure 4 , when the two protective shells 403 are rotated horizontally and placed on the material barrel, they can be clamped on the rim of the material barrel through the fixing bolts 407, the clamping plate 405 and the rubber pad 406, improving the overall stability.

[0049] The use process of the asphalt mixture stirrer provided by the present utility model is as follows:

[0050] Rotate the protective shell 403 so that the protective shell 403 rotates to be parallel to the support plate 1, then place the protective shell 403 on the material barrel, and the support frame 303 and the rotating shaft 301 are inserted into the material barrel. After loosening the fixing bolt 407, push the clamping plate 405 to move so that the rubber pad 406 contacts the material barrel, and tighten the fixing bolt 407 so that the clamping plate 405 and the rubber pad 406 can be clamped on the rim of the material barrel. Start the driving motor 201, and the driving motor 201 drives the rotating shaft 301 and the support frame 303 to rotate through the first bevel gear 202, the second bevel gear 204 and the third bevel gear 205, so that the stirring directions of the first blade 302 and the third blade 305 are opposite to stir the asphalt mixture in the material barrel;

[0051] During transportation, rotate the first blade 302 and the third blade 305 to the Figure 3 state, then loosen the fixing bolt 407, adjust the position of the clamping plate 405 and then tighten the fixing bolt 407, and rotate the two protective shells 403 to be perpendicular to the support plate 1, that is, as Figure 4 shown. At this time, the protective support mechanism 4 can protect the first blade 302, the second blade 304, the third blade 305, etc.
