Description

Technical Field

[0001] This application relates to the technical field of belt conveyors, and particularly to a mine belt conveyor. Background Art

[0002] A belt conveyor is short for a belt conveyor, which is widely used in industrial production and construction fields for transporting various items; for example, in the mining field, there are some mine belt conveyors specifically applied in the mining industry on the current market to transport ores or sediment, etc.

[0003] In currently commonly used mine belt conveyors, most of their flame-retardant conveyor belts are flat belts, or there are very shallow textures on the conveyor belts. Such belt conveyors can complete normal transportation tasks under the conditions of a relatively small slope or good working conditions in the mine. However, when the slope angle in the mine is greater than ±16 degrees, the friction coefficient between the material and the conveyor belt will be less than the downward component force coefficient generated by the gravity of the material, or in a relatively humid environment, the friction coefficient between the material and the conveyor belt will also be greatly reduced. At this time, the belt conveyor cannot maintain normal transportation work in the mine and cannot meet the on-site use requirements.

[0004] Therefore, there is room for further improvement in the mine belt conveyors in the prior art. Utility Model Content

[0005] In view of this, aiming at the technical problem that most of the flame-retardant belts of the mine belt conveyors in the above prior art are flat belts, and during transportation on large slopes or in humid environments, the friction coefficient between the material and the conveyor belt decreases, making it difficult to transport normally, this application provides a mine belt conveyor, which is provided with partition strips on the flame-retardant belt. The partition strips protrude upward relative to the flame-retardant belt, forming an effective limit on the flame-retardant belt. The partition strips will increase the friction coefficient between the material and the flame-retardant belt, enabling the flame-retardant belt to drive the material to move, so that the belt conveyor can meet the material transportation on large slopes.

[0006] This application provides a mine belt conveyor, including a flame-retardant belt, wherein partition strips and connecting pieces are provided on the flame-retardant belt, and the partition strips are connected to the flame-retardant belt through the connecting pieces;

[0007] A plurality of the partition strips are provided, and the plurality of partition strips are arranged at equal intervals. The partition strips protrude in a direction away from the flame-retardant belt.

[0008] Compared with the prior art, the flame-retardant belt of the present application is provided with partition strips. The partition strips are provided in multiple numbers and protrude away from the flame-retardant belt, so that there are multiple upward-protruding partition strips on the flame-retardant belt. When materials are transported on the flame-retardant belt, the partition strips come into contact with the materials. When transporting on a large slope, the partition strips can block the materials, increase the friction coefficient between the materials and the flame-retardant belt, and prevent the materials from sliding down, thereby ensuring that the mine belt conveyor can maintain normal working transportation; similarly, when transporting in a humid environment, the partition strips can also increase the friction coefficient between the flame-retardant belt and the materials to ensure that the mine belt conveyor can maintain normal working transportation; among them, the partition strips are connected to the flame-retardant belt through connecting pieces, so that the partition strips and the flame-retardant belt are detachably connected, that is, the partition strips can be replaced. When the partition strips are damaged, there is no need to replace the entire flame-retardant belt. Just replacing the partition strips can be reused, reducing the maintenance cost.

[0017] The side wall of the reinforcing rib is connected to the reinforcing part, and the bottom of the reinforcing rib is connected to the installation part.

[0018] Preferably, the mine belt conveyor further includes an installation bracket, an upper idler and a lower idler. The upper idler is connected to the upper part of the installation bracket, and the lower idler is arranged at the lower part of the installation bracket. The upper idler and the lower idler are used to support the flame-retardant belt.

[0019] Preferably, the lower idler is divided into a first idler and a second idler, and the first idler and the second idler are arranged at intervals;

[0020] The length of the partition strip is less than the length of the flame-retardant belt, and the first idler and the second idler are respectively used to support the flame-retardant belts at both ends of the partition strip;

[0048] Those skilled in the art should understand that in the disclosure of the present application, the orientation or positional relationship indicated by terms such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as a limitation to the present application.

[0049] The following will further describe the present application in detail with reference to the accompanying drawings. See Figures 1 to 6 description.

[0050] The present application provides a mine belt conveyor, which is used to transport materials such as minerals. As Figures 1 to 3 shown, the mine belt conveyor 1 includes a flame-retardant belt 11, a mounting bracket 14, upper idlers 17 and lower idlers 18. The upper idlers 17 are installed at the upper position of the mounting bracket 14, and the lower idlers 18 are arranged at the lower position of the mounting bracket 14. The upper idlers 17 are located above the lower idlers 18. The flame-retardant belt 11 is a closed belt structure. The flame-retardant belt 11 covers the lower ends of the upper idlers 17. The lower idlers 18 are located below the flame-retardant belt 11. The upper ends of the lower idlers 18 are in contact with the lower ends of the flame-retardant belt 11. The upper idlers 17 and the lower idlers 18 are used to support the flame-retardant belt 11 to ensure that the flame-retardant belt 11 can operate.

[0051] Specifically, in the present application, as Figures 1 to 3As shown in the figure, partition strips 12 are provided on the flame-retardant belt 11. The partition strips 12 protrude away from the flame-retardant belt 11. There are multiple partition strips 12, and the multiple partition strips 12 are equidistantly spaced. The length extension direction of the partition strips 12 is perpendicular to the moving direction of the flame-retardant belt 11. When transporting materials on the flame-retardant belt 11, the partition strips 12 come into contact with the materials. When transporting at a large slope (16 - 25 degrees), the partition strips 12 can block the materials, increase the friction coefficient between the materials and the flame-retardant belt 11, prevent the materials from sliding down, and thus ensure that the mine belt conveyor 1 can maintain normal working transportation; similarly, when transporting in a humid environment, the partition strips 12 can also increase the friction coefficient between the flame-retardant belt 11 and the materials to ensure that the mine belt conveyor 1 can maintain normal working transportation;

[0052] As Figure 3 、 Figure 6 shown in the figure, the partition strips 12 and the flame-retardant belt 11 are detachably connected through a connecting member 13, so that the partition strips 12 can be replaced. When the partition strips 12 are damaged, there is no need to replace the entire flame-retardant belt 11. Just replace the partition strips 12 to be reused, reducing the maintenance cost; in this embodiment, the partition strips 12 are made of rubber or engineering plastics, and their height is set between 30 - 50 mm. The center line of the partition strips 12 is on the same straight line as the center line of the flame-retardant belt 11; the distance between the partition strips 12 can be selected according to actual use requirements.

[0053] Furthermore, as Figure 3 、 Figure 6 shown in the figure, connecting holes 111 are provided on the flame-retardant belt 11. The connecting holes 111 penetrate through the upper and lower end faces of the flame-retardant belt 11, and at least two connecting holes 111 are provided; mounting holes 121 are provided on the partition strips 12. The mounting holes 121 penetrate through the upper and lower end faces of the partition strips 12, and the number of mounting holes 121 corresponds to the number of connecting holes 111. In this embodiment, four connecting holes 111 are provided, and each mounting hole 121 corresponds to one connecting hole 111. The axes of the mounting holes 121 and the connecting holes 111 are on the same straight line; among them, the connecting member 13 sequentially passes through the connecting holes 111 and the mounting holes 121. The end of the connecting member 13 extending beyond the mounting hole 121 is connected with a limiting member 16. The connecting member 13 is provided with threads, and the limiting member 16 is provided with a threaded hole. The limiting member 16 is detachably connected to the connecting member 13 through the threaded hole; and, the outer diameter of the limiting member 16 is larger than the aperture of the mounting hole 121. A limit is formed between the limiting member 16 and the partition strip 12. A gasket is provided between the limiting member 16 and the partition strip 12, so that after the limiting member 16 is connected to the connecting member 13, the connecting member 13 is not easily disengaged from the mounting hole 121, ensuring the connection stability and firmness between the flame-retardant belt 11 and the partition strips 12.

[0054] As Figure 6As shown, the aperture of the connection hole 111 is larger than that of the mounting hole 121, and the outer diameter of the connecting member 13 is smaller than the outer diameter of the mounting hole 121. This allows the connecting member 13 to be quickly inserted into the connection hole 111 during installation, improving the installation efficiency. At the same time, a limiting block 131 is provided at the end of the connecting member 13 close to the flame retardant strip 11. The outer diameter of the limiting block 131 is larger than the outer diameter of the connection hole 111, forming a limit between the limiting block 131 and the flame retardant strip 11, so that the connecting member 13 will not easily fall off from the connection hole 111, increasing the anti-detachment property of the partition strip 12. Among them, a reinforcing protrusion 132 is provided on the limiting block 131. The reinforcing protrusion 132 protrudes towards the partition strip 12. The reinforcing protrusion 132 is relatively thin, and its end can be set to a tip. When installing the connecting member 13, the reinforcing protrusion 132 can be inserted into the flame retardant strip 11, thereby increasing the grasping force of the connecting member 13 on the flame retardant strip 11. And the length of the reinforcing protrusion 132 is less than the thickness of the flame retardant strip 11, which can prevent the reinforcing protrusion 132 from penetrating the flame retardant strip 11 and improve the connection firmness between the connecting member 13 and the flame retardant strip 11, so that the connecting member 13 will not easily be misaligned or move with the flame retardant strip 11. Then, when the partition strip 12 is impacted by the material, the connecting member 13 can also firmly grasp the flame retardant strip 11 and the partition strip 12, making the partition strip 12 not easily come off.

[0055] It should be noted that in this embodiment, before installing the connecting member 13, sealant can be applied to the bottom of the partition strip 12 to strengthen the connection firmness between the partition strip 12 and the flame retardant strip 11.

[0056] In an alternative embodiment of the present application, as Figure 2 , Figure 3 shown, the partition strip 12 is a long rectangular structure.

[0057] In another alternative embodiment of the present application, as Figure 5 shown, the partition strip 12 is an L-shaped structure. The partition strip 12 includes a mounting portion 123 and a strengthening portion 122. The side end of the strengthening portion 122 is connected to the mounting portion 123. The height of the strengthening portion 122 is greater than the height of the mounting portion 123. Both the strengthening portion 122 and the mounting portion 123 are rectangular long strip structures. The connection between the strengthening portion 122 and the mounting portion 123 makes the partition strip 12 form an L shape. In this embodiment, the mounting hole 121 is provided on the mounting portion 123, so that the partition strip 12 is connected to the flame retardant strip 11 through the mounting portion 123. At the same time, the height of the strengthening portion 122 is set to be greater than that of the mounting portion 123, which can ensure the height of the partition strip 12, so that the blocking effect of the partition strip 12 on the material can still be maintained. And the height (thickness) of the mounting portion 123 is relatively low, reducing the depth of the hole opening on the partition strip 12, which can save materials while ensuring the blocking effect of the partition strip 12. In this embodiment, the height of the strengthening portion 122 is set between 30 - 50 mm.

[0058] Furthermore, asFigure 5 As shown, in the present embodiment, a reinforcing rib 124 is provided on the partition bar 12, and the reinforcing rib 124 is a triangular plate-like structure. The side wall of the reinforcing rib 124 is connected to the side wall of the reinforcing portion 122 toward the mounting portion 123, and the bottom of the clamping rib is connected to the upper end surface of the mounting portion 123. The reinforcing rib 124 can increase the structural strength of the connection between the reinforcing portion 122 and the mounting portion 123, so that the upper end surface of the reinforcing portion 122 protruding from the mounting portion 123 is not easily deformed; wherein, the reinforcing rib 124 and the mounting hole 121 are staggered, so that reinforcing ribs 124 are provided at both ends of the mounting hole 121, so that the reinforcing rib 124 and the mounting hole 121 are staggered, so as to avoid the reinforcing rib 124 from affecting the mounting connector 13, and can also further increase the structural strength of the partition bar 12.

[0059] On the basis of any of the above embodiments, the mining belt conveyor 1 is further expanded; Figure 1 As shown, in the present embodiment, the upper roller 17 is divided into a middle roller 171 and a side roller 172, and the side rollers 172 are symmetrically arranged on both sides of the middle roller 171, the middle roller 171 is parallel to the lower roller 18, and the angle between the middle roller 171 and the side rollers 172 is obtuse, so that the upper roller 17 forms a U-shaped structure, and the side rollers 172 at least support part of the flame retardant belt 11; wherein, the length of the spacer 12 is less than the width of the flame retardant belt 11, and the length of the spacer 12 is less than or equal to the length of the middle roller 171, so that when the flame retardant belt 11 moves, the spacer 12 can be completely supported by the middle roller 171, the spacer 12 will not be affected by the U-shaped structure of the upper roller 17, and the spacer 12 will not act on the side roller 172, that is, the spacer 12 will not be bent, which greatly ensures the uniformity of the force of the spacer 12, which is beneficial to improve the service life of the flame retardant belt 11.

[0060] On the basis of any of the above embodiments, the mining belt conveyor 1 is further expanded; Figure 1 As shown, the lower roller 18 is divided into a first roller 181 and a second roller 182, and the first roller 181 and the second roller 182 are arranged at intervals, wherein the interval between the first roller 181 and the second roller 182 is greater than the length of the partition bar 12, and the interval between the first roller 181 and the second roller 182 is less than the width of the flame retardant belt 11, so that the first roller 181 and the second roller 182 are respectively used to support the flame retardant belt 11 at both ends of the partition bar 12, when the lower roller 18 supports the flame retardant belt 11, the partition bar 12 will not contact the lower roller 18, thereby avoiding the collision between the partition bar 12 and the lower roller 18, avoiding the jumping of the partition bar 12 and the lower roller 18, so that the flame retardant belt 11 passes through the lower roller 18 smoothly, thereby ensuring the normal operation of the mining belt conveyor 1 and reducing the weight of the mining belt conveyor 1.

[0061] Based on any of the above embodiments, the mine belt conveyor 1 is further expanded; for example, Figure 4 As shown, the mine belt conveyor 1 further includes a cleaner 15. The cleaner 15 is arranged below the mounting bracket 14. The cleaner 15 is located at the lower end of the flame-retardant belt 11. The cleaner 15 is used to clean the flame-retardant belt 11 and sweep the residue materials on the flame-retardant belt 11; wherein, the cleaner 15 and the lower idler 18 are arranged at intervals, that is, the cleaner 15 and the lower idler 18 are staggered, so that the cleaner 15 does not interfere with the lower idler 18, to ensure the independence of the operation of the lower idler 18 and the front idler; for example, Figure 5 As shown, the length of the cleaner 15 is greater than the width of the flame-retardant belt 11, that is, both ends of the cleaner 15 extend beyond both sides of the flame-retardant belt 11, so that the cleaner 15 can completely and comprehensively clean the flame-retardant belt 11 and ensure the cleaning effect.

[0062] Specifically, for example, Figure 4 As shown, the cleaner 15 includes a middle cleaning part 151 and side-end cleaning parts 152. The side-end cleaning parts 152 are symmetrically arranged on both sides of the middle cleaning part 151. The middle cleaning part 151 and the side-end cleaning parts 152 are arranged on the same straight line, that is, a straight row structure is formed between the middle cleaning part 151 and the side-end cleaning parts 152; wherein, for example, Figure 4 As shown, a cleaning groove is provided on the middle cleaning part 151. The cleaning groove is recessed in the direction away from the flame-retardant belt 11. The cleaning groove corresponds to the partition strip 12. The cleaning groove is used to accommodate the partition strip 12, that is, the middle cleaning part 151 can clean the partition strip 12, so that when the cleaner 15 cleans the flame-retardant belt 11, the partition strip 12 will not jump or make abnormal noises with the cleaner 15. When the middle cleaning part 151 or the side-end cleaning parts 152 are damaged, they can be replaced independently, and it is not necessary to replace the entire cleaner 15, which can effectively save the maintenance cost.

[0063] It should be noted that in the case where the solutions of the embodiments of the present application do not conflict and the technical solutions can coexist, they can be arbitrarily combined into new embodiments.

[0064] The above has introduced the present application in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the present application and its core idea. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present application, several improvements and modifications can still be made to the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
