Description

Technical Field

[0001] This utility model relates to the technical field of road construction, and in particular to a cold recycled asphalt mixture storage device and a paver. Background Technology

[0002] Cold recycled asphalt mixture refers to a road construction material made by mixing materials milled from old asphalt pavement with newly added binders (such as emulsified asphalt, foamed asphalt, etc.), additives, and possibly new aggregates under conditions of no heating or low temperature. This material not only helps to dispose of waste materials but also reduces production costs, resulting in good economic and social benefits.

[0003] When paving cold recycled asphalt mixtures, a paver is required. In existing technologies, such as... Figure 1 The paver shown has two rotatable hoppers mounted on its frame. A platform 7 and a conveyor are installed between the two hoppers, with the platform being closer to the outer edge. During prolonged use, it was found that a significant amount of material falls onto the platform. The material originates from two sources: first, some material falls onto the platform when the unloading truck is used; second, some material falls onto the platform when the hoppers on both sides are tumbling. This material needs to be removed manually. The construction site environment is complex, and manually cleaning up materials near the paver increases the risk of accidental injury to workers, such as vehicle collisions or mechanical equipment malfunctions. Utility Model Content

[0013] The driving member is used for driving the turnover plate to rotate.

[0014] As a preferred scheme of the utility model, the hopper further comprises:

[0015] The flexible member is arranged above the inclined surface along the length direction of the inclined surface; the flexible member is used for shielding the gap between the main body and the turnover plate.

[0016] As a preferred scheme of the utility model, the hopper further comprises:

[0017] The shielding member is arranged on one side of the turnover plate close to the conveying belt II; the shielding member is partially overlapped with the conveying belt II.

[0018] As a preferred scheme of the utility model, the hopper further comprises:

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned purpose, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0034] Secondly, the "embodiment" referred to herein can include specific features, structures or characteristics contained in at least one implementation of the present application. In this specification, "in one embodiment" does not refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments. EMBODIMENT

[0035] Reference Figures 2-3The embodiment provides a cold recycled asphalt mixture storage device, which comprises a vehicle frame 1, two hoppers 2 rotatably arranged on both sides of the vehicle frame 1 and a conveying belt one 3 arranged in the middle of the vehicle frame 1, a discharge end 4 is arranged at the discharge side of the hopper 2, wherein the two hoppers 2 are driven by external power devices and can be turned over to the middle, so that the materials in the hoppers 2 flow to the conveying belt one 3, and then the materials are conveyed to a paving position by the conveying belt one 3; and the cold recycled asphalt mixture storage device further comprises:

[0036] A conveying belt two 5 is arranged in the extension direction of the conveying belt one 3, the purpose of the conveying belt two 5 is to clean the materials falling thereon, since the materials are not many, and the materials should be completely separated from the conveying belt two 5 when the conveying belt two 5 rotates once, therefore, the conveying belt two 5 should be selected to be smooth as a whole, and does not need to be provided with cross arms like the conveying belt one 3; as shown in the figure, Figure 4 The conveying belt two 5 partially overlaps the conveying belt one 3, and the purpose of the overlapping is that the materials conveyed by the conveying belt two 5 can all fall on the conveying belt one 3, and are prevented from falling on other positions;

[0037] The conveying belt two 5 is arranged at the discharge end 4 of the hopper 2, and the conveying belt two 5 is used to replace the platform in the prior art; in order to reduce the problem that the materials on the platform are manually removed, an inclined platform can also be arranged, but the effect is not as good as that of the device;

[0038] The specific operation process of the device is as follows: when the discharge vehicle dumps the cold recycled asphalt mixture into the hopper 2, since the conveying belt two 5 is located at the discharge end 4, part of the materials falling from the discharge vehicle directly falls on the conveying belt two 5, and meanwhile, when the hopper 2 is turned over, part of the materials on the hopper 2 also falls on the conveying belt two 5; when the materials thereon need to be cleaned, the conveying belt two 5 starts to operate, and the materials are conveyed along the path of the conveying belt two 5, and finally are conveyed to the conveying belt one 3 overlapping the conveying belt two 5, and then are taken away by the conveying belt one 3 and are continuously conveyed to the position needing paving, the device can effectively reduce or even eliminate the problem of the residual materials on the platform in the prior art, not only improves the working efficiency of the paver, but also enhances the safety of the construction site and reduces the demand for manual cleaning and the related cost.

[0039] Since there can be many broken slag or materials with strong adhesion in the mixture, part of the materials can not be effectively separated from the conveying belt two 5, so that the materials are left on the conveying belt two 5 and fall off during the return, causing material waste and additional cleaning work, as an optional scheme of the utility model, the device further comprises:

[0040] A scraper 6 is arranged at the discharging end of the conveying belt two 5; the scraper 6 is used to separate the materials from the conveying belt two 5, as shown in the figure, Figures 2-5 In order to completely separate the materials from the conveying belt two 5, the side of the scraper 6 close to the conveying belt two 5 is arranged to be pointed, and the scraper 6 is close to the conveying belt two 5.

[0041] In the embodiment of the application, the scraper 6 is arranged at the discharge end of the second conveying belt 5, which mainly ensures that the material can be completely separated from the second conveying belt 5 and smoothly transferred to the first conveying belt 3 when the material is conveyed to the end. The scraper 6 can effectively scrape the material attached to the conveying belt through physical contact.

[0042] In actual use, considering that there can be more material near the one end of the main body 21 close to the discharge end 4, when the main body 21 is overturned, part of the material can be moved to the second conveying belt 5, increasing the load of the second conveying belt 5, and also possibly causing part of the material to fall off the second conveying belt 5 to the ground, which undoubtedly brings new burdens. As a preferred scheme of the application, referring to Figure 2 、 Figure 3 、 Figure 6 and Figure 7 , the hopper 2 comprises:

[0043] the main body 21, which is provided with an inclined surface 22 near one side of the discharge end 4; the inclined surface 22 is inclined away from the discharge end 4 to the first conveying belt 3, and this end overlaps the first conveying belt 3 in the conveying direction of the first conveying belt 3;

[0044] the turnover plate 23, which is rotatably installed on the inclined surface 22, and more specifically, the two can be rotatably connected by using a hinge or the like;

[0045] the driving member 24, which is used to drive the turnover plate 23 to rotate;

[0046] In the embodiment of the application, when the discharge vehicle pours cold recycled asphalt mixture into the hopper 2, in order to prevent the turnover plate 23 from being crushed, the turnover plate 23 is leveled with the main body 21, and part of the material will fall on the turnover plate 23; when the hopper 2 is overturned to make the material flow to the first conveying belt 3, if no intervention is made, the material on the turnover plate 23 will flow to the second conveying belt 5 to increase the load and also possibly cause the material to flow to the ground. At this time, the driving member 24 is operated to make the turnover plate 23 overturn, at this time, the turnover plate 23 forms a funnel shape with the main body 21, so that the material on the turnover plate 23 flows to the first conveying belt 3, reducing the load of the second conveying belt 5 and not falling to other positions;

[0047] The driving member 24 can adopt various forms, for example, an electric telescopic rod, an oil cylinder or a gas cylinder drive, but the above-mentioned ways will all cause the height to increase, which undoubtedly increases the distance between the vehicle frame 1 and the main body 21. The driving member 24 of the device adopts the following structure: as Figure 4 、 Figure 6 and Figure 7As shown, the driving member 24 comprises a motor 241 fixed to the bottom of the main body 21, one end of a driving rod 242 is fixed to the output shaft of the motor 241, the other end of the driving rod 242 is fixed with a pushing shaft 243, a long strip plate 244 is fixed to the bottom of the turnover plate 23, the long strip plate 244 is provided with a long strip hole, and the pushing shaft 243 penetrates through the long strip hole; when it is required to rotate the turnover plate 23, the motor 241 is started to rotate the driving rod 242 and the pushing shaft 243, since the pushing shaft 243 penetrates through the long strip hole, the turnover plate 23 can be rotated by the pushing shaft 243 during the rotation of the driving rod 242, and during the rotation, the relative position between the pushing shaft 243 and the long strip hole changes.
