Description

Technical Field

[0001] The utility model belongs to the field of machinery, and in particular relates to a hollow spiral belt material roller for a belt conveyor. Background Art

[0002] In the process of transporting materials, the belt conveyor is prone to deviation due to the diversity of the transported materials. The deviation will cause the conveyor belt to produce lateral friction, and the edge wear will increase, which will reduce the efficiency of the conveyor. At the same time, deviation may also cause the material to fall back, thereby increasing the friction between the belt and the roller, thus shortening their service life. If not handled in time, it will not only increase energy consumption, but also shorten the service life of the equipment. Because when the belt conveyor deviates, the conveyor belt will collide with or wear bearings, rollers and other components, which will reduce production at the least, and may even cause significant economic losses at the worst.

[0003] At present, the basic forms of belt conveyor rollers are generally cylindrical rollers and trough rollers. When handling a large amount of materials, the existing cylindrical rollers will cause the materials to be mixed between the belt and the rollers, and the belt will deviate due to unevenness on both sides. Although the existing trough rollers can alleviate the problem of material inclusion to a certain extent, over time, the materials will accumulate on the inside of the belt, press the belt, and make the belt longer. If the belt is too long, the torque transmission between the transmission parts will be incomplete, thereby reducing the output power of the motor. The motor will also generate noise during operation, affecting its use. In addition, if the belt is too long, it will easily lead to uneven friction between the belt and the hub, which will increase the wear of the belt and affect its service life. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model designs a hollow spiral material carrier roller for a belt conveyor. The hollow spiral material carrier roller adopts the form of an internal spiral of the roller to transport the entrained material while ensuring the structural strength of the roller, thereby ensuring that the belt does not deviate due to material inclusions. The operating cost, equipment stability and implementation safety are greatly improved.

[0005] The specific contents are as follows:

[0006] One of the purposes of the utility model is to provide a hollow spiral belt roller for a belt conveyor, which comprises a cylindrical hollow roller body and a main shaft penetrating through the roller body and coaxial with the roller body;

[0007] The main shaft is fixedly connected with a spiral discharging plate arranged around it; the spiral discharging plate is arranged inside the roller body; the main shaft is fixedly connected to the roller body; the side surface and bottom surface of the cylindrical roller body are both hollow structures.

[0008] When using the above-mentioned hollow spiral belt material supporting roller for a belt conveyor, it is installed on the belt conveyor. The belt conveyor has two rollers, an active roller and a driven roller. Taking the case where the active roller is at a higher position and the driven roller is at a lower position as an example: the driven roller at the lower position is the hollow spiral belt material supporting roller of the present invention. During the upward transmission of materials, some fine materials fall into the inner side of the belt from the gap between the belt and the side plate. Under the action of the belt running direction and gravity, all these materials rush to the lower-end driven roller. The materials fall into the roller through the hollow part of the roller body. Through rotation, the materials are conveyed out by the spiral discharge plate inside the supporting roller, ensuring that the belt does not deviate due to material jamming. If the driven roller is a cylindrical solid roller, it will cause materials to be clamped between the belt and the supporting roller, and the material accumulation is uneven, resulting in belt deviation. The spiral discharge plate can not only send out the jammed materials through rotation, but also serve as the support for the external roller body. In addition, under the action of gravity, the materials on the upper side of the belt conveyor, the lighter or smoother materials will slide down, resulting in a certain amount of materials accumulating in front of the baffle plate set at the lower end of the belt. The accumulated materials will squeeze into the space between the belt and the supporting roller from the gap between the belt and the side plate. The supporting roller of the present invention will scrape the materials adhered to the inner side of the belt into the inner side of the supporting roller, and under the action of centrifugal force, the materials are spun out through the spiral discharge plate.

[0009] Further, the side surface of the roller body is preferably composed of a plurality of threaded steel pipes in the same direction as its axis. The threaded steel pipes increase the friction force, avoid belt slippage, and play a certain role in scraping slag on the materials adhered to the inner side of the belt. Specifically, the threaded steel pipes are preferably arranged uniformly along the circumference of the cylinder.

[0010] Further, fastening rings for fixing the threaded steel pipes are preferably provided on both end faces of the roller body. The fastening rings play a role in fixing and positioning the threaded steel pipes, ensuring the rigidity of the supporting roller.

[0011] The second object of the present invention is to provide a belt conveyor, and the belt conveyor includes the above-mentioned hollow spiral belt material supporting roller.

[0012] Specifically, it is preferably to set the hollow spiral belt material supporting roller for the belt conveyor at the lower end of the belt conveyor. During the conveying process, fine materials fall to the supporting roller at the lower end. The materials fall into the roller through the hollow part of the roller body. Through rotation, the materials are conveyed out by the spiral discharge plate inside the supporting roller, ensuring that the belt does not deviate due to material jamming.

[0013] The beneficial effects of the present invention are as follows:

[0014] This utility model abandons the design scheme of traditional solid rollers, and realizes the structural replacement from blockage to dredging in principle, greatly reducing the possibility of belt deviation of the belt conveyor. Moreover, this utility model reduces the number of times of adjusting the belt, greatly reducing the labor maintenance cost; reduces the energy consumption, increases the service life of the equipment and its parts; effectively improves the production efficiency and reduces the production cost of the enterprise.

[0028] Install the above hollow spiral belt roller on the belt conveyor. Figure 6 As shown, the belt conveyor has two rollers, the active roller 2 and the driven roller 1. Take the example that the active roller 2 is at a high position and the driven roller 1 is at a low position: the driven roller 1 at the low position is the hollow spiral belt roller mentioned above. When the above belt conveyor is working, the active roller 2 rotates to drive the belt to transport materials upward. During the upward transmission of materials, some fine materials fall into the inner side of the belt from the gap between the belt and the side plate. Under the action of the belt running direction and gravity, these materials are all rushed into the low-end driven roller 1. The materials fall into the roller from the hollow part of the roller body. Through rotation, the materials are transported out by the spiral discharge plate 1-2 inside the roller to ensure that the belt does not deviate due to material inclusions. In addition, as Figure 7 As shown, under the action of gravity, the lighter or slippery materials on the upper side of the belt conveyor will slide downward, resulting in a certain amount of material accumulation in front of the baffle plate 3 set at the lower end of the belt. The accumulated materials will be squeezed into the gap between the belt and the side plate and between the belt and the driven roller 1. The above-mentioned hollow spiral belt roller will scrape the material adhered to the inner side of the belt into the inner side of the roller. Under the action of centrifugal force, the material is rotated out through the spiral discharge plate 1-2.
