[0037] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0038] It should be noted that many specific details are elaborated in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific implementation methods disclosed below.

[0039] like Figure 1-2 As shown, the utility model provides an asphalt station belt cleaning mechanism, comprising a frame 1, a storage hopper 2 arranged on the frame 1, and a belt conveyor arranged below the storage hopper 2, the belt conveyor comprising a first conveyor belt 31 and second conveyor belts 32 arranged on both sides of the first conveyor belt 31; and in the vertical direction, the belt surface height of the second conveyor belt 32 is lower than the belt surface height of the first conveyor belt 31; the side of the second conveyor belt 32 close to the first conveyor belt 31 is located below the first conveyor belt 31. Figure 2 As shown, as a preferred embodiment of the present application, the portion of the second conveyor belt 32 on the side close to the first conveyor belt 31 extends under the first conveyor belt 31, and the portion of the second conveyor belt 32 on the side away from the first conveyor belt 31 is outside the coverage area of ​​the first conveyor belt 31. In a preferred example, the coverage area of ​​the portion of the second conveyor belt 32 extending under the first conveyor belt 31 accounts for no more than two-fifths of the overall coverage area of ​​the second conveyor belt 32.

[0040] The second conveyor belts 32 arranged on both sides of the first conveyor belt 31 can effectively receive the leaked materials falling from the edge of the first conveyor belt 31, and can directly and synchronously convey the leaked materials, thereby integrating the recovery and utilization steps of the leaked materials together, greatly improving the efficiency of the recovery and utilization of the leaked materials during the aggregate transportation process, avoiding the need for a separate recycling device, and saving installation space and equipment costs.

[0041] As a preferred embodiment of the present application, refer to Figure 1 As shown, the first conveyor belt 31 and the second conveyor belt 32 are both provided with belt ribs 33. The provision of the belt ribs 33 can further reduce the material leakage of the first conveyor belt 31. Since the leaked material has been buffered by the second conveyor belt 32 when falling on the second conveyor belt 32, the provision of the belt ribs 33 can also prevent aggregates from falling from the second conveyor belt 32.

[0042] As a preferred embodiment of the present application, refer to Figure 3 As shown, along the conveying direction, a scraper assembly is provided at the upper front end of the belt rib. Figure 3 As shown, the scraper assembly includes a fixed plate 61 arranged in the vertical direction, a scraper drive 63 and a scraper plate 62 connected to the fixed plate 61, and the scraper plate 62 can move relative to the first conveyor belt 31 in the vertical direction under the drive of the scraper drive 63. Preferably, the scraper drive 63 is a cylinder. In one example, when the material level inside the silo reaches the limit, the control component controls the drive motor 5 to pause and stop loading, and then controls the cylinder to drive the scraper plate 62 to move down to the surface of the first conveyor belt 31, and then controls the drive motor 5 to reverse and scrape the excess material on the belt through the scraper plate 62 for easy recycling, and can further clean the belt surface, with high efficiency and good cleaning effect. In another example, a belt steering device is also provided, which can adjust the direction of the belt conveyor after the belt conveyor stops running, adjust the direction of the belt conveyor after the loading stops, and then control the cylinder to drive the scraper plate 62 to move down to the surface of the first conveyor belt 31, and then control the drive motor 5 to rotate forward or reverse to scrape off the excess material on the belt and clean the belt surface through the scraper plate 62. The above scheme is automatically completed through the control of the control part, which greatly improves the automation and intelligence of the entire equipment and reduces labor intensity.

[0043] Further, refer to Figure 1 As shown, a discharge port 21 is provided at the lower portion of the storage hopper 2, and a first conveyor belt 31 is provided below the discharge port 21. Figure 1 As shown, the belt conveyor further includes a buffer device, which is arranged below the first conveyor belt 31; and in the vertical direction, the buffer device is arranged below the discharge port 21; the buffer device can support the first conveyor belt 31. In one example, referring to Figure 1 As shown, the frame 1 is provided with a bracket 11 , and the buffer device is arranged on the upper part of the bracket 11 .

[0044] Furthermore, refer to Figure 1 As shown, the buffer device includes a support plate 41 and an elastic member 42 arranged below the support plate 41 and connected to the support plate 41; in the vertical direction, the support plate 41 is arranged below the discharge port 21 and the first conveyor belt 31; under the action of the elastic member 42, the upper surface of the support plate 41 can contact the lower surface of the first conveyor belt 31.

[0045] In actual use, the first conveyor belt 31 will be impacted by the falling aggregates and vibrate when receiving the aggregates, which will cause the aggregates to bounce to a certain height when falling on the surface of the first conveyor belt 31, and then the aggregates will fall and leak. In addition, the surface of the first conveyor belt 31 will be continuously impacted during long-term use, which will shorten its service life. The buffer device can absorb part of the kinetic energy of the aggregates falling from the discharge port 21 to the first conveyor belt 31, thereby reducing the impact of the aggregates on the surface of the first conveyor belt 31. On the one hand, it can reduce the vibration of the surface of the first conveyor belt 31 and thus reduce the amount of leakage. At the same time, it can also reduce the damage to the surface of the first conveyor belt 31 caused by the impact of the falling aggregates, which is conducive to extending the service life of the first conveyor belt 31.

[0046] It should be noted here that the present application does not specifically limit the type and specific structure of the elastic member 42. The elastic member 42 can be a shock-absorbing spring or a shock-absorbing cylinder, or it can also be other elastic shock-absorbing devices or structures of more different types and structures.

[0047] As a preferred embodiment of the present application, the upper surface of the supporting plate 41 is a smooth plane, thereby reducing the friction resistance between the supporting plate 41 and the first conveyor belt 31 and minimizing the influence of the supporting plate 41 on the normal operation of the first conveyor belt 31.

[0048] Further, refer to Figure 1 and Figure 2 As shown, the belt conveyor also includes a driving device, which includes a first driving component that cooperates with the first conveyor belt 31 and a second driving component that cooperates with the second conveyor belt 32; the first driving component includes a driving motor 5 and a first active roller 34 connected to the driving motor 5, and also includes a first driven roller 37, and the first conveyor belt 31 is sleeved on the first active roller 34 and the first driven roller 37; the second driving component includes a second driven roller 35, and the second driven roller 35 is connected to the first active roller 34 through a transmission member 36, so that it can rotate under the drive of the first active roller 34.

[0049] In one example, referring to Figure 1 and Figure 2As shown, the transmission member 36 is a transmission belt, and the first active roller 34 and the second driven roller 35 have belt grooves that match the transmission belt. The belt grooves are set at both ends of the first active roller 34 and the second driven roller 35, and the transmission belt is sleeved on the belt grooves at both ends of the first active roller 34 and the second driven roller 35. When the first active roller 34 rotates under the drive of the drive motor 5, it can not only drive the first conveyor belt 31 to rotate, but also transmit power to the second driven roller 35 through the transmission belt, thereby driving the second conveyor belt 32 to rotate synchronously. And because the amount and quality of the leaked clinker carried by the second conveyor belt 32 are smaller than the amount and quality of the aggregate carried by the first conveyor belt 31, driving the second drive belt at the same time will not increase the load of the drive motor 5 too much, but can make full use of the power of the drive motor 5 to improve work efficiency. In another example, the transmission member 36 is a transmission chain, the first active roller 34 and the second driven roller 35 have transmission gear teeth that match the transmission chain, and the setting positions of the transmission chain and the transmission gear teeth can refer to the setting positions of the aforementioned transmission belt and belt groove.

[0050] It should also be noted here that the coordination and transmission methods of the above-mentioned first conveyor belt 31 and the second conveyor belt 32 are only preferred examples of the present application, and more different transmission methods such as gear transmission and synchronous belt transmission may also be adopted, and the present application does not make any specific limitation on this.

[0051] As a preferred embodiment of the present application, refer to Figure 1 As shown, a plurality of discharge ports 21 and buffer devices are provided, and the discharge ports 21 and buffer devices are provided in a one-to-one correspondence.

[0052] The technical solution protected by the present utility model is not limited to the above-mentioned embodiments. It should be pointed out that the combination of the technical solution of any embodiment with the technical solution of one or more other embodiments is within the protection scope of the present utility model. Although the present utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to it based on the present utility model. Therefore, these modifications or improvements made without departing from the spirit of the present utility model are within the scope of protection claimed by the present utility model.
