DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and beneficial effects of the present invention clearer, the preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technicians.

[0030] In the description of the present invention, unless otherwise specified, the terms "left", "right", "up", "down", etc., indicating directions or state relationships, are based on the directions or state relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0031] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "provided with" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, it is easy to understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0032] like Figure 1-8 As shown, the mobile recycled material mixing device comprises a support plate 9 with four wheels 10 at the bottom, a traction frame 11 connected to the support plate 9, and a mixer 8, a heating device, a dust collecting device, an asphalt conveying device and a recycled material feeding device arranged on the support plate 9. The four end feet at the bottom of the support plate 9 are respectively provided with jacks 31, the top rod of the jack 31 faces downward, and the base is fixed to the lower end surface of the support plate 9.

[0033] The structure of the utility model is an improvement on the patent with publication number CN215051791U. Since the mixer 8 and the asphalt conveying equipment are both arranged on the support plate 9, the mixing of the mixer 8 and the operation of the asphalt pump 13 are both vibrating, so the support plate 9 needs to have strong stable support. During highway maintenance, the mixer is parked on the maintenance road surface. When the road surface is rugged or there is a slope, it is difficult to stably support the support plate 9 by only four wheels 10. Since there are many mountain roads in Yunnan, especially county roads and township roads, the slope is large, and the road surface is surrounded by cliffs or deep trenches, when the road surface is maintained, the utility model can only be parked on the road surface, and the stable support of the support plate 9 cannot be guaranteed. By respectively arranging jacks 31 at the four end feet of the support plate 9, the base of the jack 31 is bolted to the support plate 9, and when support is needed, the extension length of the top rod of the jack 31 is adjusted, and the support plate 9 is supported by the jack 31 to ensure the stability of the support plate 9.

[0034] A shock-absorbing steel plate 30 is provided between the wheel 10 and the support plate 9 to reduce shock to the support plate 9 .

[0035] A steering wheel 4 is connected between the support plate 9 and the shock-absorbing steel plate 30 of the front wheel. The shock-absorbing steel plate 30 and the support plate 9 can rotate through the steering wheel 4. The traction frame 11 is connected to the shock-absorbing steel plate 30 of the front wheel. The angle between the traction frame and the support plate 9 can be adjusted through the rotation of the shock-absorbing steel plate 30 and the support plate 9, thereby increasing the rotation angle of the traction frame 11 and the support plate 9 during towing, which is more suitable for traveling on roads with large bends. The steering wheel 4 can be any structure that can realize the mutual rotation of the shock-absorbing steel plate 30 and the support plate 9. For example, the steering wheel 4 includes a rotating column 5 and a rotating drum 6. A groove ring 14 is provided in the middle of the rotating column 5. The rotating drum 6 is sleeved on the rotating column 5, and a convex ring 15 matching the groove ring 14 and engaging in the groove ring 14 and rotating along the groove ring 14 is provided on the inner wall. The rotating column 5 and the rotating drum 6 are rotatably sleeved by the groove ring 14 and the convex ring 15. The rotation of the convex ring 15 along the groove ring 14 realizes the mutual rotation of the rotating column 5 and the rotating drum 6. Flanges 33 are provided at the bottom of the rotating column 5 and the top of the rotating drum 6 respectively. The rotating column 5 is flange-connected with the shock-absorbing steel plate 30, and the rotating drum 6 is flange-connected with the support plate 9.

[0036] As a preferred solution, the traction rod 32 of the traction frame 11 is a Z-shaped rod. When the utility model needs to be moved, the Z-shaped structure can reduce the connection height of the traction frame 11, making it safer and smoother during driving. At the same time, the Z-shaped traction rod 32 is more convenient when the traction frame is disassembled.

[0037] The mixer 8 is provided with a receiving hopper 16, and the recycled material feeding equipment is the same as the patent with publication number CN215051791U, including two conveying tracks 1, a conveying hopper 2 and a tractor 3. The two conveying tracks 1 are tiltedly arranged at the right end of the support plate 9, and the bottom of the conveying hopper 2 is provided with a roller matching the conveying track 1; the tractor 3 is connected to the conveying hopper 2 through a double-line pull rope. The conveying track 1 includes an upper fixed section 1-1 and a lower folding section 1-2, and the upper fixed section 1-1 and the lower folding section 1-2 can be folded and hinged through a 180-degree folding hinge; the sides of the upper fixed section 1-1 and the lower folding section 1-2 are respectively provided with a hinged hanging ring 27 and a hook 28. When it is necessary to transport asphalt recycled materials, the 180-degree folding hinge is opened to facilitate the transportation of the conveying hopper 2. When it is necessary to transport the utility model to the construction site, the conveying track 1 is folded, and the hook 28 is hung in the hanging ring 27, so as to shorten the length of the conveying track 1 and facilitate transportation.

[0038] The dust collecting equipment includes a dust collecting hood 22, a dust collecting pipe 23 and a dust collecting box 24; the dust collecting hood 22 and the dust collecting box 24 are connected through the dust collecting pipe 23, and the dust collecting hood 22 is arranged above the feed port of the mixer. The dust collecting hood 22 collects the dust generated during the feeding process and recycles it into the dust collecting box through the dust collecting pipe 23.

[0039] The asphalt conveying equipment includes an asphalt tank 12 and an asphalt pump 13. The inlet pipe of the asphalt pump 13 is connected to the asphalt tank 12, and the outlet pipe is inserted into the mixer 8. The recycled material feeding equipment adds recycled materials such as crushed stone into the mixer 8, and mixes and stirs them with the asphalt conveyed by the asphalt pump 13 in the mixer 8.

[0040] The mixer 8 and the asphalt tank 12 are both provided with heating jackets. The heating equipment includes a fuel tank 20 and a burner 21. The fuel tank 20 is connected to the burner 21 through a pipeline, and the burner 21 outlet pipe is connected to the heating jackets of the mixer 8 and the asphalt tank 12. The mixer 8 and the asphalt tank 12 are heated by the burner 21 to prevent the asphalt from solidifying due to the temperature drop.

[0041] The utility model is also provided with a control box 19, which is used to control the operation of the mixer 8 and the asphalt pump 13. Since the operation of the equipment controlled by the control box 19 is a conventional technology, the utility model will not repeat the connection between the control box 19 and the mixer 8 and the asphalt pump 13.

[0042] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
