[0030] Specifically, the utility model adopts a hollow design inside the outer barrel 1, and a stirring mechanism is provided inside. The asphalt is stirred by the stirring mechanism. The stirring mechanism of the utility model can stir the asphalt evenly and can clean the asphalt adhered to the inner wall of the outer barrel, so that the stirring device can be used for a long time and the stirring effect is good.
[0031] Specifically, the stirring mechanism includes a turntable 4, which is used to receive a stirring motor 11, a slider 18 and a connecting rod driving motor 13, wherein the stirring motor 11 is fixed to the inner wall of the outer barrel by a stirring motor fixing sleeve 6 and a fixing rod 5, wherein the turntable 4 is fixed to the rotating shaft of the stirring motor 11; wherein, there are at least two fixing rods 5, or more; preferably, two are provided, and two are symmetrically provided, and the design structure of the two is simple and can stabilize the placement of the motor and the turntable.
[0032] Specifically, the stirring motor 11 is used to drive the stirring vertical rod 7, the stirring connecting rod 8, the stirring horizontal rod 9, the stirring blade 10 and the turntable 4 to rotate synchronously. The rotation of the stirring blade 10 can stir the asphalt.
[0033] Specifically, the stirring vertical rod 7 is designed to penetrate the turntable 4.
[0034] Specifically, the function of the connecting rod driving motor 13 is to drive the stirring connecting rod 8 to move left and right, and drive the stirring blade 10 to move left and right. When the stirring blade 10 moves to be close to the inner wall of the outer barrel 1, the stirring blade rotates under the rotation of the stirring motor 11, and will scrape off the asphalt adhered to the inner wall of the outer barrel 1, thereby achieving the purpose of cleaning.
[0035] In this example, slide grooves 19 are provided at the left and right ends of the inner wall of the through hole 12 , and plastic hinges 20 are provided on the slide grooves 19 . The front and rear ends of the plastic hinges 20 are fixed on the front and rear ends of the slide grooves 19 .
[0036] Specifically, the plastic hinge 20 is a folded and ductile plastic hinge, and both ends of the plastic hinge are fixed in the slide groove 19 .
[0037] The specific function of the plastic fold 20 is to prevent the asphalt mixture from splashing onto the rotating disk 4 from the through hole 12 during the mixing process, thereby affecting other components.
[0038] In this example, the slider 18 is disposed above the through hole 12 , and the top end of the stirring vertical rod 7 passes through the plastic fold 20 and is fixedly connected to the slider 18 .
[0039] Specifically, the plastic fold 20 is provided with a hole for the stirring vertical rod 7 to pass through, the hole is in close contact with the rod body of the stirring vertical rod, and a sealant is provided at the connecting end to prevent asphalt splashing in the gap.
[0040] In this example, both the upper gear rod 15 and the lower gear rod 16 have teeth for meshing with the gear 14 for transmission.
[0041] Specifically, the connecting rod drives the motor to start, driving the gear 14 to rotate, driving the upper gear rod 15 and the lower gear rod 16 to engage and transmit, so that the upper gear rod 15 and the lower gear rod 16 move toward each other, and drive the corresponding slider connecting rod 17 to move toward each other, and drive the corresponding slider 18 to move, and then drive the stirring connecting rod 8 to move, and then drive the stirring blade 10 to move, so that the stirring blade 10 can be close to the center of the inner part of the outer barrel 1 or close to the inner wall of the outer barrel 1. When close to the center, it is in a stirring state, because the stirring blade is in the center position, and the stirring blade 10 can better drive the asphalt to rotate when it rotates; when close to the inner wall of the outer barrel 1, it is in a cleaning state. At this time, with the clean water cleaning of the water inlet, the asphalt adhering to the inner wall can be scraped off and cleaned. Among them, the clean water outlet is not shown in the figure, and the clean water outlet is arranged below the turntable.
[0042] In this example, the stirring cross bar 9 includes a cross bar sleeve 21 fixedly mounted on the stirring vertical rod 7 , and a telescopic cross bar 22 telescopically connected to the cross bar sleeve 21 , and one end of the telescopic cross bar 22 is fixedly connected to the stirring connecting rod 8 .
[0043] Specifically, in order to enable the stirring blade 10 to move, the stirring cross bar 9 is a telescopic rod, wherein the telescopic cross bar 22 can move relative to the cross bar sleeve 21 .
[0044] In this example, the size of the turntable 4 is smaller than the size of the inner wall of the outer barrel 1 , and the turntable 4 is fixedly connected to the rotating shaft of the stirring motor 11 and rotates along with the rotation of the rotating shaft of the stirring motor 11 .
[0045] In this example, the size of the slider 18 is larger than the size of the through hole 12 .
[0046] Specifically, the slider 18 moves on the through hole 12, and the through hole 12 has a guiding function. In order to enable the slider 18 to move smoothly, the size of the slider 18 is larger than the size of the through hole so that the slider 18 will not sink into the through hole 12. When the slider moves left and right, it drives the stirring connecting rod to move, and the plastic fold 20 is in the action of extension and contraction, but it can always cover the through hole 12 to prevent splashing.
[0047] In this example, a plurality of stirring blades 10 are longitudinally arranged, and the cross-section of the stirring blades 10 is in an arc shape.
[0048] Specifically, there are multiple stirring bars 9, so there are also multiple stirring blades arranged on the stirring bar 9, and multiple stirring blades can better stir evenly;
[0049] Specifically, the stirring vertical rod 7, the stirring connecting rod 8 and the stirring horizontal rod 9 in the utility model all have the function of breaking up the asphalt mixture, and cooperate with the stirring blade 10 to make the asphalt mixture more evenly stirred.
[0050] In this example, the outer barrel 1 is further provided with a feed inlet 23 and a discharge outlet 24 .
[0051] Specifically, the size of the turntable 4 of the utility model is slightly smaller than the inner wall size of the outer barrel 1, preferably, just enough for the turntable 4 to rotate. This design prevents the asphalt mixture from splashing onto the turntable.
[0052] Specifically, the stirring motor 11 and the connecting rod driving motor 13 are both designed to be waterproof and anti-corrosion, that is, they can be designed using sealant or other means.
[0053] Beneficial effects of the utility model:
[0054] The stirring blade can move left and right, so that when the stirring blade is close to the center of the outer barrel, it can stir, and when it is close to the inner wall of the outer barrel, it can scrape off the adhered asphalt mixture, so the cleaning effect is good.
[0055] Second, a plastic fold is provided through the through hole to prevent the asphalt mixture from splashing onto the turntable, ensuring safe use.
[0056] Third, the stirring rod, stirring cross bar and stirring blade work together to stir the asphalt mixture more evenly, while saving stirring time and improving efficiency.
[0057] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
