Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors and relates to a distribution structure of rollers of a belt conveyor. Background Art

[0002] Belt conveyors are commonly used bulk material conveying equipment, and they have many specific forms. The most common structural forms are: Figure 1 , Figure 2 As shown, it includes a plurality of long straight roller frames distributed at intervals along the conveying path; a plurality of rollers are mounted on the roller frames through corresponding supporting members, and the overall crimping surfaces of the plurality of rollers are adapted to the bottom surface of the conveying belt driven by the motor; the roller frames are a plurality of A roller frames 2A distributed at intervals along the conveying path; A roller 1A, B roller 1B, and C roller 1C are mounted on the A roller frame 2A through corresponding supporting members, and the ends of the rollers are sequentially arranged close to each other, and the axes of the three rollers form a three-section two-fold concave shape as a whole, wherein the axis of the B roller 1B located in the middle is horizontally arranged, and the axes of the A roller 1A and the C roller 1C are respectively arranged at obtuse angles to the axis of the B roller 1B.

[0003] The distribution structure of belt conveyor rollers using such technology can certainly be used, but its shortcomings are:

[0004] A. After the material is loaded, the cross-section of the conveyor belt is arc-shaped and concave. The combination line of the roller crimping surface arranged in three sections of two-fold notches is not well enough in fit with the crimping surface of the conveyor belt. After long-term use, the conveyor belt is prone to local fatigue cracking at the two-fold inflection point.

[0005] B, there are only three rollers on each roller frame 2A, the rolling resistance of the conveyor belt is relatively large, and the energy consumption of the motor is relatively large.

[0006] C. The axes of the three rollers 1A, 1B and 1C are in the same vertical plane. Although the transmission is relatively stable, the transported bulk materials are not easy to automatically gather to the center of the conveyor belt. In the actual production process, if the bulk materials can be automatically gathered to the center of the conveyor belt, the workload of manual intervention can be reduced, which is more important than excessive transmission stability.

[0007] D. Since there are only three rollers on each first rolling frame 2A, the carrying capacity of the conveyor belt is not large enough. Utility Model Content

[0008] In order to overcome the deficiencies of the prior art, the utility model provides a distribution structure of belt conveyor rollers, the conveyor belt is more durable, the energy consumption is lower, the conveyed bulk materials are more easily and automatically gathered to the center of the belt, the conveyor belt has a larger carrying capacity, and the use effect is more ideal.

[0009] The technical solution adopted by the utility model to achieve the above technical purpose is: a distribution structure of belt conveyor rollers, including a plurality of long straight roller frames distributed at intervals along the conveying path; a plurality of rollers are mounted on the roller frames through corresponding supporting members, and the overall crimping surfaces of the plurality of rollers are adapted to the bottom surface of the conveying belt driven by the motor, and the roller frames are a plurality of B roller frames distributed at intervals along the conveying path; a first roller, a second roller, a third roller, a fourth roller, a fifth roller, a sixth roller, a seventh roller, an eighth roller, and a ninth roller are mounted on the B roller frames through corresponding supporting members, and the ends of the nine rollers are adjacent to each other in sequence and the axes of adjacent rollers are staggered front and back along the conveying direction.

[0010] The axes of the first roller, the third roller, the seventh roller and the ninth roller are tangent to the arc line A; the axes of the second roller, the fourth roller, the sixth roller and the eighth roller are tangent to the arc line B; the axis of the fifth roller located in the middle and lowest position is set horizontally; the arc line A and the axis of the fifth roller and the arc line B are distributed in sequence front and back along the conveying direction.

[0011] The beneficial effects of the utility model are: due to the adoption of the above structure, it has the following advantages:

[0012] A. Since the roller frame 2B is equipped with nine rollers, the pressing surfaces of the nine rollers fit better with the pressing surfaces of the conveyor belt, the conveyor belt is not prone to local fatigue cracking, and the conveyor belt is more durable;

[0013] B. Since the roller frame 2B is equipped with nine rollers, the rolling friction of the conveyor belt is smaller and the energy consumption is lower;

[0014] C. Since the ends of the nine rollers are close to each other and the axes of the adjacent rollers are staggered in the conveying direction, the transported bulk materials will be subjected to more obvious vibration similar to the road brake belt when passing through each roller frame 2B, and will be more likely to automatically gather in the center of the belt, which can reduce the workload of manual intervention;

[0015] D. Since roller rack 2B is equipped with nine rollers, the conveyor belt has a larger carrying capacity;

[0016] In summary, the utility model is more durable, has lower energy consumption, the transported bulk materials are more easily automatically gathered to the center of the belt, the conveyor belt has a larger carrying capacity, and the use effect is more ideal. BRIEF DESCRIPTION OF THE DRAWINGS
