Description

Technical Field

[0001] This utility model relates to the field of belt conveyor hoppers, and more particularly to a belt conveyor receiving hopper. Background Technology

[0002] Belt conveyors are widely used in metallurgy, power and other fields and are important material conveying equipment. The current common technology for preventing crushing and reducing wear on belt conveyors is to install a buffer device under the belt in the receiving section. This device mainly protects the idlers and supports, not the belt itself. In daily use, the materials conveyed by the belt conveyor have a huge impact on the belt, especially large pieces of minerals with sharp corners and edges, which can easily tear the belt.

[0003] In existing technology, to reduce the impact on the belt, during the material transfer process, the upper and lower belt conveyors are transferred through a funnel. After the material rebounds through the funnel, it enters the lower belt. When the funnel receives the material, it is subjected to the impact of granular materials such as ore, which is very easy to wear. The funnel consists of a funnel body and a wear-resistant liner. The body material is steel plate, and the wear-resistant liner is installed at the material drop point of the funnel body and is made of manganese steel. Compared with the material falling directly onto the belt, this can reduce the impact of the material on the belt and extend the service life of the lower belt.

[0004] While the above technical solutions can mitigate the impact of materials on the belt to some extent, they still cause impacts when conveying irregular materials. This can affect the overall lifespan of the belt, requiring more frequent maintenance and replacement, increasing equipment operating costs and downtime, and indirectly negatively impacting production efficiency. Utility Model Content

[0005] To address the technical problem of belt conveyors being impacted during material receiving in the prior art, this invention provides a belt conveyor receiving funnel that further enhances the funnel's protective effect on the belt and prevents materials from causing significant impact on the belt.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: a conveyor belt receiving hopper, including a hopper body and a material leakage grid. The material leakage grid is horizontally arranged in the hopper body. The material leakage grid includes multiple horizontal plates and multiple vertical plates. The outermost horizontal plates and vertical plates are provided with inclined surfaces. The inclined surfaces are in contact with the inner wall of the hopper body.

[0007] This invention, by setting a material leakage grid in the funnel body, can further distribute the impact of materials on the funnel body, reduce the impact force of materials falling on the belt, reduce damage to the belt, and extend the service life of the belt.

[0008] Furthermore, the outermost horizontal plate and / or the vertical plate are provided with lifting lugs.

[0009] This utility model facilitates the hoisting of the material leakage grid by setting up lifting lugs.

[0010] Furthermore, the multiple horizontal plates and multiple vertical plates intersect to form multiple squares, and the material leakage grid also includes multiple wear-resistant liners, which are disposed on the inner wall of the squares.

[0011] This invention enhances the strength of the material leakage grid and extends its service life by incorporating wear-resistant liners.

[0012] Furthermore, the grid and the wear-resistant liner are detachably connected.

[0013] This invention allows for the detachable connection of wear-resistant liners, which facilitates the replacement of worn liners and avoids the need to replace the entire material leakage grid. Furthermore, it enables flexible adjustment of the liner installation position according to the impact range of the material, thereby improving the flexibility of the material leakage grid.

[0014] Furthermore, the grid and the wear-resistant liner are connected by bolts, and two bolts are provided.

[0015] Furthermore, the top of the wear-resistant liner is higher than the top of the horizontal plate and the vertical plate.

[0016] This invention, by setting a protruding material-leaking grid on the wear-resistant liner, allows material to accumulate between two adjacent wear-resistant liners, forming protection for the top surfaces of the horizontal and vertical plates, and preventing material from directly impacting the top and causing wear and cracking of the grid.

[0017] Furthermore, the top of the wear-resistant liner is provided with a guide slope, which is inclined towards the inside of the grid.

[0018] This invention reduces the impact of materials on the top of the wear-resistant liner by setting a guide slope, extends the service life of the wear-resistant liner, and facilitates the passage of materials through the feed grid.

[0019] Furthermore, at least two wear-resistant lining plates are provided on each inner wall of the grid.

[0020] This invention achieves screening of large materials by setting multiple wear-resistant liners on the inner wall of the grid, avoiding large materials from causing a large impact on the conveyor belt and further enhancing the protection effect.

[0021] As can be seen from the above technical solutions, this utility model has the following advantages:

[0022] This utility model provides a conveyor belt receiving funnel. By incorporating a material-discharging grid within the funnel body, the impact of materials is further distributed, reducing the impact force of materials falling onto the conveyor belt, minimizing belt damage, and extending the belt's service life. Lifting lugs facilitate the hoisting of the material-discharging grid. Wear-resistant liners enhance the grid's strength and extend its service life. The detachable connection of the wear-resistant liners facilitates replacement of worn liners, avoiding the need to replace the entire material-discharging grid, and allows for flexible adjustment of the liners according to the impact range of the materials. The installation position enhances the flexibility of the material leakage grid; by setting the wear-resistant liners to protrude from the material leakage grid, materials can accumulate between two adjacent wear-resistant liners, forming protection for the top surfaces of the horizontal and vertical plates, preventing materials from directly impacting the top and causing wear and cracking of the grid; by setting the guide slope, the impact of materials on the top of the wear-resistant liners can be reduced, extending the service life of the wear-resistant liners, and facilitating the passage of materials through the material leakage grid; by setting multiple wear-resistant liners on the inner wall of the grid, large materials can be screened, preventing large materials from causing large impact forces on the conveyor belt, further enhancing the protective effect.

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0029] like Figure 1 and Figure 2 As shown in the figure, this specific embodiment provides a conveyor belt receiving hopper, including a hopper body 5 and a material discharge grid 6; the material discharge grid 6 is horizontally arranged inside the hopper body 5, and the material discharge grid 6 includes multiple horizontal plates 2 and multiple vertical plates 1. The outermost horizontal plates 2 and vertical plates 1 are provided with inclined surfaces, and the inclined surfaces are in contact with the inner wall of the hopper body 5; wherein, the number of horizontal plates 2 and vertical plates 1, as well as the size of the squares formed by the intersection of horizontal plates 2 and vertical plates 1, can be customized according to the size of the material.

[0030] This specific embodiment, by setting a material leakage grid 6 in the funnel body 5, can further distribute the impact of the material on the funnel body 5, reduce the impact force of the material falling on the belt, reduce damage to the belt, and extend the service life of the belt.

[0031] In this specific embodiment, the funnel has a conical structure, and the material falls from the center of the funnel body 5. The material leakage grid 6 can be horizontally placed inside the funnel body 5. Therefore, in order to facilitate disassembly and assembly, the outermost horizontal plate 2 and / or the vertical plate 1 are provided with lifting lugs. In order to improve the installation stability, the material leakage grid 6 can also be welded to the inner wall of the funnel body 5.

[0032] like Figure 2 As shown, to improve the strength and extend the service life of the material leakage grid 6, the material leakage grid also includes multiple wear-resistant liners 3, which are disposed on the inner wall of the grid. Preferably, the grid and the wear-resistant liners 3 are detachably connected. This arrangement facilitates the replacement of worn liners, avoiding the replacement of the entire material leakage grid 6. Furthermore, since materials of different specific gravities have different diffusion ranges when falling on the material leakage grid 6 (the greater the specific gravity, the smaller the diffusion range), the detachable connection of the liners allows for flexible adjustment of the liner installation position according to the impact range of the material, thus improving the flexibility of the material leakage grid 6. The wear-resistant liners 3 can be installed by engaging the grooves on the inner wall of the grid. In this specific embodiment, the grid and the wear-resistant liners 3 are connected by bolts 4, and two bolts 4 are provided to prevent the wear-resistant liners 3 from deflecting.

[0033] like Figure 2As shown, furthermore, the top of the wear-resistant liner 3 is higher than the top of the horizontal plate 2 and the vertical plate 1. With this arrangement, when the material initially falls, material accumulates between the two wear-resistant liners 3 of two adjacent squares, forming protection for the top surfaces of the horizontal plate 2 and the vertical plate 1. This prevents the material from continuously impacting the top surfaces of the horizontal plate 2 and the vertical plate 1, causing wear and cracking of the plates, and extending the service life of the material leakage grid 6.

[0034] like Figure 2 and Figure 3 As shown in this specific embodiment, the top of the wear-resistant liner 3 is provided with a guide slope 301, which is inclined inward towards the inside of the grid. This arrangement facilitates the passage of material through the discharge grid 6. At the same time, compared with the horizontal top surface, the guide slope 301 can reduce the impact of material on the top of the wear-resistant liner 3 and extend the service life of the wear-resistant liner 3.

[0035] To prevent large materials from causing significant impact on the conveyor belt when falling, at least two wear-resistant liners 3 can be installed on the inner wall of each grid. This reduces the cross-sectional area of ​​the grid, preventing larger materials from falling and further enhancing the protection of the conveyor belt.

[0036] The wear-resistant liner 3 can be made of steel-chromium alloy or high-manganese steel.

[0037] As can be seen from the above specific embodiments, this utility model has the following beneficial effects:

[0038] 1. By setting a material leakage grid 6 in the funnel body 5, the impact of the material can be further distributed on the basis of the funnel body 5, reducing the impact force of the material falling on the belt, reducing the damage to the belt, and extending the service life of the belt; the material leakage grid 6 can be easily hoisted by setting lifting lugs.

[0039] 2. By setting wear-resistant lining plates 3, the strength of the material leakage grid 6 can be enhanced, and the service life of the material leakage grid 6 can be extended;

[0040] 3. By detachably connecting the wear-resistant liner 3, it is convenient to replace the worn liner and avoid replacing the entire material leakage grid 6. On the other hand, the installation position of the liner can be flexibly adjusted according to the impact range of the material, thus improving the flexibility of the material leakage grid 6.

[0041] 4. By setting the protruding material leakage grid 6 on the wear-resistant liner 3, the material can accumulate between two adjacent wear-resistant liners 3, forming protection for the top surface of the transverse plate 2 and the longitudinal plate 1, and avoiding the material from directly impacting the top and causing the grid to wear and crack.

[0042] 5. By setting the guide slope 301, the impact of material on the top of the wear-resistant liner 3 can be reduced, the service life of the wear-resistant liner 3 can be extended, and the material can pass through the discharge grid 6.

[0043] 6. By setting multiple wear-resistant liners 3 on the inner wall of the grid, large materials can be screened, avoiding large materials from causing a large impact on the belt and further enhancing the protection effect.

[0044] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
