Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of tobacco processing equipment, and in particular to a dust cover for a conveyor belt and a conveyor belt. Background Technology
[0002] When tobacco leaves are threshed and re-dried, they need to be transported by a conveyor belt. There is often a height difference between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt. When the tobacco leaves are transported from the discharge end of the conveyor belt to the inlet end of the adjacent conveyor belt, the falling tobacco leaves will generate dust and pollute the working environment. Therefore, a dust cover is installed at the connection between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt to prevent dust from splashing.
[0003] In the existing technology, because it is necessary to clean the dust inside the dust cover regularly, a cleaning port is opened on the dust cover and a cover is set to cover the cleaning port. One side of the cover is pivotally connected to the dust cover, and the other side is magnetically or snap-fit connected to the cover. After long-term use, the magnet is easy to fall off and the snap is easy to fail, resulting in poor sealing between the dust cover and the cover, causing dust to overflow.
[0004] There is an urgent need for a dust cover for conveyor belts and a conveyor belt to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. To this end, this invention provides a dust cover and conveyor belt that achieves a reliable seal between the dust cover and the cover plate, preventing dust from spilling into the working environment.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] In a first aspect, a dust cover for a conveyor belt is provided, disposed at the connection between the discharge end of the conveyor belt and the inlet end of an adjacent conveyor belt, the dust cover for the conveyor belt comprising:
[0008] The cover has an internal space for accommodating the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt. The cover is provided with a cleaning port communicating with the accommodating space, an inlet facing the discharge end of the conveyor belt, and an outlet facing the inlet end of the adjacent conveyor belt. The inlet and the outlet are respectively connected to the accommodating space.
[0009] A shielding plate, the first end of which is pivotally connected to the cover, the shielding plate being rotatable between a shielded position that shields the cleaning port and an open position that avoids the cleaning port, the second end of which is located below the first end, and when the shielding plate is in the shielded position, the second end overlaps the cover.
[0010] The locking assembly includes an inner liner plate, which is fixedly connected to the side of the shielding plate near the receiving space.
[0011] Preferably, one end of the inner liner is bent and extended toward the receiving space to form a guide plate, and when the shielding plate is in the shielding position, the guide plate shields the second end.
[0012] Preferably, the locking assembly further includes a snap-fit component, which is fixedly connected to the inner wall of the cover and located within the receiving space. When the shielding plate is in the shielding position, the snap-fit component and the guide plate can snap into each other, and the shielding plate can undergo elastic deformation under force to separate the snap-fit component and the guide plate.
[0013] Preferably, the dust cover for the conveyor belt further includes a rotating assembly, which includes a first rotating member and a second rotating member rotatably connected to each other. The first rotating member is fixedly connected to the cover body, and the second rotating member is fixedly connected to the shielding plate.
[0014] Preferably, the second end of the shielding plate is bent and extended in a direction away from the receiving space to form a folded plate.
[0015] Preferably, the dust cover for the conveyor belt further includes an adsorption assembly, which includes a first adsorption element and a second adsorption element. One of the first adsorption element and the second adsorption element is fixedly connected to the folding plate, and the other is fixedly connected to the cover body. When the shielding plate is in the shielding position, the first adsorption element and the second adsorption element adsorb each other.
[0016] Preferably, the adsorption assembly further includes an elastic element, which is sleeved on the outside of one of the first adsorption element and the second adsorption element, and faces the other of the first adsorption element and the second adsorption element.
[0017] Preferably, the dust cover for the conveyor belt further includes a curtain, one end of which is fixedly connected to the cover body and used to cover the feed inlet; and / or one end of which is fixedly connected to the cover body and covers the discharge outlet.
[0018] Preferably, the cover is also provided with an exhaust port, which is connected to the dust removal device through a pipe.
[0019] Secondly, a conveyor belt is provided, characterized in that it includes the aforementioned dust cover for the conveyor belt, wherein the dust cover is disposed at the connection between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt.
[0020] Beneficial effects:
[0021] The dust cover for conveyor belts provided by this utility model has a receiving space inside the cover to accommodate the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt. The cover has a cleaning port communicating with the receiving space, an inlet facing the discharge end of the conveyor belt, and a discharge port facing the inlet end of the adjacent conveyor belt. This allows the discharge end of the conveyor belt to extend into the receiving space of the cover through the inlet, while the inlet end of the adjacent conveyor belt is located within the receiving space and can extend out of the receiving space through the discharge port. Tobacco leaves are transported from the inlet to the discharge end of the cover and fall to the inlet end of the adjacent conveyor belt, and then transported out of the receiving space through the discharge port. Dust generated by falling leaves is confined within the enclosure of the hood and does not contaminate the working environment. The first end of the shielding plate is pivotally connected to the hood, allowing it to rotate between a shielded position that covers the cleaning port and an open position that avoids the cleaning port. The second end of the shielding plate is located below the first end. When the shielding plate is in the shielded position, the second end overlaps the hood, ensuring that the shielding plate remains in contact with the hood due to its own weight, thus maintaining the reliability of the seal between the hood and the shielding plate. By fixing the inner lining plate to the side of the shielding plate closest to the enclosure, the weight of the shielding plate can be increased, further improving the seal between the hood and the shielding plate.
[0022] The conveyor belt provided by this utility model, by setting the dust cover for conveying the belt at the connection between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt, can prevent dust generated by the falling material from spilling into the working environment when conveying materials.

[0036] Figure 1 A schematic diagram of the structure of the dust cover for the conveyor belt provided in this embodiment is shown. Figure 2 yes Figure 1 A magnified view of a portion of point A in the middle. Figure 3 yes Figure 1 A magnified view of a portion at point B. (See diagram below.) Figures 1 to 3As shown, the dust cover for conveyor belts provided in this embodiment is installed at the connection between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt. The dust cover for conveyor belts includes a cover body 1, a shielding plate 2, and a locking assembly 3. The cover body 1 has an accommodating space 11 for accommodating the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt. The cover body 1 is provided with a cleaning port 12 communicating with the accommodating space 11, an inlet facing the discharge end of the conveyor belt, and an outlet facing the inlet end of the adjacent conveyor belt. The material inlet and the discharge outlet are respectively connected to the receiving space 11; the first end 21 of the shielding plate 2 is pivotally connected to the cover 1, and the shielding plate 2 can rotate between the shielding position that shields the cleaning port 12 and the open position that avoids the cleaning port 12. The second end 22 of the shielding plate 2 is located below the first end 21. When the shielding plate 2 is in the shielding position, the second end 22 overlaps the cover 1; the locking assembly 3 includes an inner lining plate 31, which is fixedly connected to the plate surface of the shielding plate 2 on the side close to the receiving space 11.
[0037] It should be noted that the dust cover for conveyor belts provided in this embodiment can not only prevent dust generated by falling tobacco leaves from polluting the working environment, but also confine the dust generated by any material that falls between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt to the containment space 11 of the cover body 1, and prevent it from overflowing into the working environment.
[0038] The dust cover for conveyor belts provided in this embodiment has a receiving space 11 inside the cover body 1 for accommodating the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt. The cover body 1 is provided with a cleaning port 12 communicating with the receiving space 11, an inlet facing the discharge end of the conveyor belt, and a discharge port facing the inlet end of the adjacent conveyor belt. This allows the discharge end of the conveyor belt to extend into the receiving space 11 of the cover body 1 through the inlet, while the inlet end of the adjacent conveyor belt is located inside the receiving space 11 and can extend out of the receiving space 11 through the discharge port. Tobacco leaves can be transported from the inlet end of the cover body 1 to the discharge end and fall to the inlet end of the adjacent conveyor belt, and then transported out of the receiving space 11 through the discharge port. The dust generated by the falling tobacco leaves Dust is confined within the containment space 11 of the cover 1 without contaminating the working environment; the first end 21 of the shielding plate 2 is pivotally connected to the cover 1, and the shielding plate 2 can rotate between the shielded position of the cleaning port 12 and the open position of the cleaning port 12. The second end 22 of the shielding plate 2 is located below the first end 21. When the shielding plate 2 is in the shielded position, the second end 22 overlaps the cover 1, so that the shielding plate 2 is always overlapped with the cover 1 due to its own weight, thereby maintaining the sealing reliability between the cover 1 and the shielding plate 2; by fixing the inner lining plate 31 to the plate surface of the shielding plate 2 near the containment space 11, the weight of the shielding plate 2 can be increased to further improve the sealing between the cover 1 and the shielding plate 2.
[0039] like Figures 1 to 2 As shown, one end of the inner lining plate 31 is bent and extended toward the receiving space 11 to form a guide plate 311. When the shielding plate 2 is in the shielding position, the guide plate 311 shields the second end 22, thereby changing the direction of dust dispersion when the dust inside the receiving space 11 drifts toward the second end 22 of the shielding plate 2, and preventing the dust from overflowing from the second end 22 of the shielding plate 2 to the outside of the receiving space 11 at the overlapping position of the cover 1 and the cover 2.
[0040] Continue as Figures 1 to 2 As shown, the locking assembly 3 also includes a snap-fit component 32, which is fixedly connected to the inner wall of the cover 1 and located within the receiving space 11. When the shielding plate 2 is in the shielding position, the snap-fit component 32 and the guide plate 311 can snap into each other. The shielding plate 2 can be elastically deformed under force, causing the snap-fit component 32 and the guide plate 311 to separate. Thus, when the shielding plate 2 is in the shielding position, it prevents the cover 1 from vibrating and causing relative displacement between the cover 1 and the shielding plate 2. At the same time, when it is necessary to open the shielding plate 2 and rotate it from the shielding position to the open position, the operator can forcefully deform the shielding plate 2 to separate the snap-fit component 32 and the guide plate 311, thereby allowing the operator to rotate the shielding plate 2 and open it, so that the operator can clean the dust remaining in the receiving space 11 of the cover 1 through the cleaning port 12. Specifically, the snap-fit component 32 is a snap-fit hook, and the guide plate 311 is snapped into the snap-fit hook, thereby improving the stability of the connection between the shielding plate 2 and the cover 1.
[0041] like Figure 3 Combination Figure 1 As shown, the dust cover for the conveyor belt also includes a rotating assembly 4. The rotating assembly 4 includes a first rotating component 41 and a second rotating component 42 that are rotatably connected to each other. The first rotating component 41 is fixedly connected to the cover body 1, and the second rotating component 42 is fixedly connected to the shielding plate 2, thereby improving the stability of the shielding plate 2 relative to the cover body 1. Specifically, the rotating assembly 4 is a hinge, the first rotating component 41 is a first blade, and the second rotating component 42 is a second blade. The first blade and the second blade are rotatably connected to each other. The first blade has a first through hole, and the cover body 1 has a first threaded hole. A bolt passes through the first through hole and is threadedly connected to the first threaded hole, thereby fixing the first blade to the cover body 1. The second blade has a second through hole, and the shielding plate 2 has a second threaded hole. A bolt passes through the second through hole and is threadedly connected to the second threaded hole, thereby fixing the second blade to the shielding plate 2.
[0042] like Figure 2 Combination Figure 1As shown, the second end 22 of the shielding plate 2 bends and extends away from the receiving space 11 to form a folding plate 23, so that when it is necessary to open the shielding plate 2 to clean the receiving space 11 of the cover 1, the staff can directly hold the folding plate 23 to open the shielding plate 2 conveniently.
[0043] Continue as Figure 2 Combination Figure 1 As shown, the dust cover for the conveyor belt also includes an adsorption assembly 5, which includes a first adsorption element 51 and a second adsorption element 52. One of the first adsorption element 51 and the second adsorption element 52 is fixedly connected to the folding plate 23, and the other is fixedly connected to the cover body 1. When the shielding plate 2 is in the shielding position, the first adsorption element 51 and the second adsorption element 52 attract each other, thereby further improving the stability of the connection between the shielding plate 2 and the cover body 1. Specifically, the first adsorption element 51 is a magnet, and the second adsorption element 52 is a magnetic base. The magnet and the magnetic base can attract each other magnetically to prevent the cover body 1 from vibrating and causing relative displacement between the cover body 1 and the shielding plate 2, thus creating a gap between the cover body 1 and the shielding plate 2, further improving the sealing performance between the shielding plate 2 and the cover body 1.
[0044] In some embodiments, the adsorption assembly 5 further includes an elastic element 53, which is sleeved on the outside of one of the first adsorption element 51 and the second adsorption element 52, and faces the other of the first adsorption element 51 and the second adsorption element 52. When the shielding plate 2 is rotated to close the shielding plate 2, it prevents rigid impact between the first adsorption element 51 and the second adsorption element 52, thus preventing damage to the adsorption element. Specifically, the elastic element 53 can be a rubber pad, a silicone pad, or a sponge pad, and its interior has a sleeve cavity whose contour matches the outer contour of the first adsorption element 51 or the second adsorption element 52. The sleeve cavity of the elastic element 53 engages with the outer contour of the first adsorption element 51 or the second adsorption element 52, thereby achieving a reliable connection between the elastic element 53 and the first adsorption element 51 or the second adsorption element 52.
[0045] In this embodiment, the elastic member 53 has a sleeve cavity whose contour matches the outer contour of the first adsorption member 51. The sleeve cavity of the elastic member 53 is sleeved and fitted with the outer contour of the first adsorption member 51, so that when the shielding plate 2 moves from the open position to the shielding position, the second adsorption member 52 first impacts the elastic member 53, reducing the rigid impact on the first adsorption member 51 and the second adsorption member 52.
[0046] Dust generated by falling materials can spill into the working environment not only through the gap between the cleaning port 12 and the shielding plate 2, but also from the inlet facing the discharge end of the conveyor belt and the outlet facing the inlet of the adjacent conveyor belt. To solve the above technical problems, the dust cover for the conveyor belt also includes a curtain. One end of the curtain is fixedly connected to the cover body 1 and is used to cover the inlet, thereby preventing dust in the receiving space 11 from spilling into the working environment through the inlet. It should be noted that when the material on the conveyor belt enters the receiving space 11 of the cover body 1 through the inlet, the curtain deforms without affecting the normal entry of the material into the receiving space 11 of the cover body 1.
[0047] Similarly, one end of the baffle is fixedly connected to the cover 1 and is used to cover the discharge port, thereby preventing dust in the receiving space 11 from overflowing into the working environment through the discharge port. It should be noted that when the material on the adjacent conveyor belt is transported to outside the receiving space 11 of the cover 1 through the discharge port, the baffle deforms without affecting the normal transport of the material to outside the receiving space 11 of the cover 1.
[0048] In some embodiments, the cover 1 is further provided with an exhaust port 13, which is connected to a dust removal device through a pipe, thereby enabling the dust in the accommodating space 11 of the cover 1 to be sucked to the dust removal device for processing, reducing the frequency of opening the shielding plate 2 when cleaning the accommodating space 11 of the cover 1, and reducing the labor intensity of the workers. Specifically, the dust removal device can be a gravity dust collector, an inertial dust collector, or a centrifugal dust collector, etc. Any dust removal device capable of removing dust is within the protection scope of this utility model, and will not be described in detail here.
[0049] It should be noted that although the dust can be sucked out of the containment space 11 of the cover 1 by the dust removal device, some dust is easy to accumulate in the cleaning dead corner. Therefore, although the dust removal device can reduce the cleaning frequency of the containment space 11 of the cover 1, it is still necessary to open the shield 2 regularly to clean the containment space 11 of the cover 1.
[0050] In some embodiments, the dust cover for the conveyor belt also includes a transparent plate, and an observation opening is provided on the dust cover. The transparent plate is fixed to the observation opening and covers the observation opening, so that the staff can directly observe the dust accumulation inside the housing space 11 of the cover 1 from the outside of the cover 1. When too much dust accumulates, the shielding plate 2 can be opened and the housing space 11 of the cover 1 can be cleaned.
[0051] This embodiment also provides a conveyor belt, including the above-mentioned dust cover for the conveyor belt. The dust cover for the conveyor belt is disposed at the connection between the discharge end of the conveyor belt and the inlet end of the adjacent conveyor belt, so as to prevent dust generated by the falling material from overflowing into the working environment when the material is being conveyed.
[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
