Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to a five-roller deep groove belt conveyor device. Background Technology

[0002] In steep-angle material transport scenarios such as coal mines and other mining industries, traditional belt conveyors typically employ a four-roller structure with a relatively simple roller layout. This results in insufficient support and constraint for materials at steep angles, leading to material slippage and spillage. This not only wastes materials and increases production costs but also pollutes the working environment and disrupts normal production. Furthermore, traditional rollers are prone to belt wear, necessitating frequent belt replacements, increasing equipment maintenance costs and downtime, and reducing production efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a five-roller deep groove belt conveyor to address the above-mentioned technical problems and prevent materials from falling off the belt.

[0004] This utility model provides a five-roller deep groove belt conveyor device, which includes several upper roller structures arranged along the middle crossbeam of the frame, with the belt laid on the surface of the upper roller structures:

[0005] Each upper roller structure consists of 5 symmetrical rollers forming a deep groove. The 5 rollers are arranged in double rows, with the double rows of rollers staggered vertically. The bottom row of rollers includes a middle load-bearing roller and auxiliary load-bearing rollers located on both sides of the middle load-bearing roller. The top row of rollers includes 2 edge-limiting rollers. Both the auxiliary load-bearing rollers and the edge-limiting rollers are inclined, and the bottom of the edge-limiting rollers and the top of the auxiliary load-bearing rollers are projected onto the vertical plane.

[0006] In one embodiment, the tilt angle of the auxiliary support roller is greater than the tilt angle of the edge limiting roller.

[0007] In one embodiment, the device further includes a number of fixed structures arranged along the middle crossbeam of the frame; the upper roller structure is connected to the middle crossbeam through the fixed structures, and the number of fixed structures is the same as the number of upper roller structures and corresponds one-to-one.

[0008] In one embodiment, the fixing structure consists of eight symmetrical supports; the eight supports are arranged in two rows, and the two rows of supports are staggered front to back.

[0009] The rear support includes two intermediate supports and auxiliary supports located outside each intermediate support; the front support includes a first limiting support located between the intermediate supports and the auxiliary supports, and a second limiting support located outside each auxiliary support.

[0010] In one embodiment, each bracket is provided with a mounting groove for mounting the roller shaft head;

[0011] The mounting slots on each intermediate bracket are used to install the shaft head on one side of the intermediate load-bearing idler and the shaft head on one side of the auxiliary load-bearing idler, respectively; the mounting slots on each auxiliary bracket are used to install the shaft head on the other side of the auxiliary load-bearing idler, respectively; the mounting slots on each first limiting bracket are used to install the shaft head on one side of the edge limiting idler; and the mounting slots on each second limiting bracket are used to install the shaft head on the other side of the edge limiting idler.

[0012] The height of the mounting slots for each bracket decreases sequentially in the order of the second limiting bracket, auxiliary bracket, first limiting bracket, and intermediate bracket.

[0013] In one embodiment, the device further includes a plurality of material blocking devices arranged along the middle crossbeam of the frame; the number of material blocking devices is the same as the number of upper idler structures and corresponds one-to-one; the material blocking devices are located above the belt on the surface of the upper idler structure and are used to make the material evenly distributed on the surface of the belt.

[0014] In one embodiment, the material blocking device includes a mounting bracket fixed to a middle crossbeam, a crossbar connecting the mounting brackets, and a material blocking plate fixed to the crossbar, the bottom of which extends above the belt on the surface of the upper idler roller structure.

[0015] In one embodiment, the bottom shape of the baffle plate is the same as that of the upper roller structure, and a gap is left between the baffle plate and the belt; the baffle plate is flexible.

[0016] In one embodiment, each mounting bracket is provided with a bracket that can move up and down along the mounting bracket; a crossbar is mounted on the bracket.

[0017] In the aforementioned five-idler deep-groove belt conveyor, each upper idler structure consists of five symmetrical idlers forming a deep groove. The five idlers are arranged in double rows, with the two rows staggered vertically. The bottom row of idlers includes a central support idler and auxiliary support idlers located on both sides of the central support idler. The top row of idlers includes two edge-limiting idlers. Both the auxiliary support idlers and the edge-limiting idlers are inclined, and the bottom of the edge-limiting idlers and the top of the auxiliary support idlers are projected onto the vertical plane. Compared to the existing three-idler or four-idler structures, this upper idler structure distributes a larger inclination angle across the five idlers, providing more stable support for the belt laid on the surface of the upper idler structure. This makes the curvature of the belt surface smoother, allowing the belt to better wrap around the material and preventing the material from falling off the belt. Moreover, the deep-groove structure provides a larger material holding space, improving the conveyor efficiency of the belt conveyor. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] In one alternative embodiment, such as Figure 1 As shown, a five-roller deep groove belt conveyor is provided. In this embodiment, the device includes a plurality of upper roller structures 30 arranged along the middle crossbeam 20 of the frame 10, and the belt is laid on the surface of the upper roller structures 30.

[0026] like Figure 2 and Figure 3As shown, each upper idler structure 30 consists of five symmetrical idlers forming a deep groove; the five idlers are arranged in double rows, with the double rows of idlers staggered vertically. The bottom row of idlers includes a central support idler 31 and auxiliary support idlers 32 located on both sides of the central support idler 31, while the top row of idlers includes two edge-limiting idlers 33. Both the auxiliary support idlers 32 and the edge-limiting idlers 33 are inclined, and the bottom of the edge-limiting idler 33 coincides with the projection of the top of the auxiliary support idler 32 in the vertical plane.

[0027] It should be noted that the tilt angle of the auxiliary support roller 32 is greater than that of the edge limiting roller 33, making the upper roller structure a deep groove shape with the opening extending outward. By setting the tilt angle gradually, the belt deformation on the surface of the upper roller structure becomes smooth, without obvious bends. On the one hand, this provides more stable support for the belt, and on the other hand, it allows the belt to better wrap around the material, preventing the material from falling off the belt.

[0028] Optionally, the idlers in this device can be made of polymer materials (such as nitrile rubber and polyurethane rubber) to reduce friction between the belt and the idlers, extend the service life of the belt, and thus ensure the stable operation of the belt conveyor.

[0029] Optional, such as Figure 2 As shown, several fixed structures 40 can also be arranged along the middle crossbeam 20 of the frame 10; the upper idler structure 30 is connected to the middle crossbeam 20 through the fixed structures 40, so that the upper idler structure 30 can be stably fixed on the middle crossbeam 20, avoiding loosening and displacement of the upper idler structure 30 during belt conveying, and improving the stability of the belt conveying device.

[0030] The number of fixed structures 40 is the same as the number of upper roller structures 30 and they correspond one-to-one, so that they can be fixed separately when multiple upper roller structures are set.

[0031] Optional, such as Figure 4 As shown, the fixed structure 40 can be composed of 8 symmetrical supports; the 8 supports are arranged in two rows, and the two rows of supports are staggered front and back; wherein, the rear row supports include 2 intermediate supports 41 and auxiliary supports 42 located outside each intermediate support 41; the front row supports include a first limiting support 43 located between the intermediate supports 41 and the auxiliary supports 42 respectively, and a second limiting support 44 located outside each auxiliary support 42.

[0032] Optional, such as Figure 4As shown, each bracket can be provided with a mounting groove 50 for mounting the roller shaft head; wherein, the mounting groove 50 on each intermediate bracket 41 is used to mount one side shaft head of the intermediate bearing roller 31 and one side shaft head of the auxiliary bearing roller 32 respectively; the mounting groove 50 on each auxiliary bracket 42 is used to mount the other side shaft head of the auxiliary bearing roller 32 respectively; the mounting groove 50 on each first limiting bracket 43 is used to mount one side shaft head of the edge limiting roller 33; the mounting groove 50 on each second limiting bracket 44 is used to mount the other side shaft head of the edge limiting roller 33.

[0033] For example, such as Figure 4 As shown, each intermediate bracket 41 is provided with two mounting slots 50 of the same height. One mounting slot 50 is located on the right-angle support leg of the intermediate bracket 41, and the other mounting slot 50 is located on the inclined support leg of the intermediate bracket 41. The auxiliary bracket, the first limiting bracket, and the second limiting bracket are each provided with one mounting slot 50. The height of the mounting slots of each bracket decreases in the following order: second limiting bracket 44, auxiliary bracket 42, first limiting bracket 43, and intermediate bracket 41.

[0034] The two shaft ends of the intermediate bearing idler 31 are respectively fixed in the mounting grooves 50 of the right-angle legs of the two intermediate supports 41, thereby stably fixing the intermediate bearing idler 31 horizontally on the intermediate crossbeam 20; the two shaft ends of the auxiliary bearing idler 32 are respectively fixed in the mounting grooves 50 of the inclined legs of the intermediate support 41 and the mounting grooves 50 of the auxiliary bearing support 42, so that the auxiliary bearing idler 32 has an inclination; the two shaft ends of the edge limiting idler 33 are respectively fixed in the mounting grooves of the first limiting support 43 and the second limiting support 44, so that the edge limiting idler 33 has a greater inclination than the auxiliary bearing idler 32, thereby enabling the upper idler structure 30 to maintain a stable deep groove shape, providing stable support for the belt, making the belt deformation smoother, and thus better wrapping the material and preventing the material from falling off the belt.

[0035] In an optional embodiment, such as Figure 1 As shown, the device may also include a number of material blocking devices 60 arranged along the middle crossbeam 20 of the frame 10; the number of material blocking devices 60 is the same as the number of upper idler roller structures 30 and corresponds one-to-one; the material blocking devices 60 are located above the belt on the surface of the upper idler roller structure.

[0036] Understandably, due to the inclination angle of the idlers in the upper idler structure 30, the material may be unevenly distributed on the belt during transport. If the height of the material exceeds the edge height of the belt, there is a risk that the material will fall off the belt during transport. The material blocking device 60 can ensure that the material is evenly distributed on the belt, preventing the material from falling off.

[0037] Optional, such as Figure 2 As shown, the material blocking device 60 may include a mounting bracket 61 fixed on the intermediate crossbeam 20, a crossbar 62 connected and fixed between the mounting brackets 61, and a material blocking plate 63 fixed on the crossbar 62. The bottom of the material blocking plate 63 extends above the belt on the surface of the upper idler roller structure 30. The bottom shape of the material blocking plate 63 is the same as that of the upper idler roller structure 30, and there is a gap between the material blocking plate 63 and the belt. When the belt moves past the material blocking plate, the material blocking plate can limit the material on the belt to a certain height, preventing the material from falling off the belt because it is higher than the edge of the belt.

[0038] Optionally, the baffle 63 may be flexible, and the material used for the baffle 63 may include rubber and plastic. When the material transport speed is high, a flexible baffle can ensure that the material passes smoothly with the belt, while a rigid baffle may cause a large amount of material to accumulate outside the baffle, which may result in a large amount of material falling off the belt or the belt conveyor malfunctioning.

[0039] Optional, such as Figure 2 As shown, each mounting bracket 61 may be provided with a bracket 64 that can move up and down along the mounting bracket 61; a crossbar 62 is installed on the bracket 64. By moving the bracket 64 up and down, the baffle plate 63 can be moved, thereby changing the height and angle of the baffle plate 63, thus providing a better material blocking effect.

[0040] Optionally, the frame 10 may also include several lower V-shaped support legs, each of which may be equipped with a lower V-shaped idler roller group. Each lower idler roller group consists of two idler rollers in the same row, forming a V-shaped angle between the two idler rollers, which can apply a stronger lateral restraint force to the belt, on the one hand preventing the belt from running off-track, and on the other hand ensuring the belt's capacity and preventing materials from falling off the belt.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this utility model.

[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
