Description

Technical Field

[0001] The utility model belongs to the technical field of belt conveyors, and in particular relates to a tail cleaning device for a belt conveyor. Background Art

[0002] Belt conveyors include three-roller belt conveyors, single-roller belt conveyors, air cushion belt conveyors and other belt conveyor equipment. This type of conveyor equipment will bring dust and some materials to the tail of the machine during operation, and accumulate there. After a long time, it will cause material blockage at the tail of the machine, and in serious cases, the equipment will be stopped. Therefore, more and more manufacturers are studying how to remove the accumulated materials at the tail of the machine to ensure the stable operation of the equipment. In addition to manual cleaning, there are two general automatic cleaning methods:

[0003] 1. Vertical cleaning scraper

[0004] A "C"-shaped scraper conveyor is set at the tail. The scraper conveyor runs in the direction of the belt. After the material is brought to the tail of the machine, it falls into the "C"-shaped scraper conveyor and is conveyed to the upper layer of the belt conveyor and enters the conveying process again, thus avoiding the accumulation of materials at the tail of the machine. The C-shaped scraper scheme has the following problems:

[0005] (1) The scraper design is complex. The scraper requires a very large structure, multiple supports in the middle, and a double-chain lifting structure. It is necessary to coordinate related synchronization issues. The structure is complex and reliability issues are more likely to occur.

[0006] (2) The cost of the tail is high, and the complex structure makes the overall manufacturing complex, which greatly increases the weight and the cost;

[0007] It is difficult to tension and arrange the tensioning structure at the tail of the machine. It is necessary to design a complex gravity tensioning scheme on the whole machine. For example, when the equipment distance is short, the general design is to achieve it through tail tensioning. However, when this tail solution is adopted, gravity tensioning must be configured, which greatly increases the cost and process layout difficulty.

[0008] (3) It is difficult to adjust the deviation of the tail. Generally, there is a screw adjustment structure at the tail, which can easily correct the belt deviation problem. However, this solution does not have a screw adjustment structure, and the deviation must be adjusted by other means. The relative efficiency is not as high as the tail wheel adjustment.

[0009] (4) The tail size is too large. When arranging the tunnel environment, the tunnel size needs to be increased, resulting in an increase in civil engineering costs;

[0010] (5) The maintenance of the tail wheel is cumbersome. As a component that is more easily damaged on the belt conveyor, the tail wheel needs to be inspected and repaired frequently, or even replaced. However, the structure is extremely complicated to replace and needs to be disassembled as a whole, which is extremely inefficient.

[0011] 2. Horizontal cleaning scraper

[0012] A circular scraper conveyor is arranged in the vertical direction around the belt conveyor. When the material accumulates at the tail of the machine, the circular scraper will lift the material upward to the upper layer of the belt, unload the material and drop it onto the belt to re-enter the conveying cycle, thereby avoiding material blockage at the tail of the machine. The circular scraper scheme has the following problems: (1) The cleaning efficiency is low. The material brought to the upper layer by the circular scraper will fall near the tail wheel when it falls, while the belt near the tail wheel is in a completely flat state. In addition, due to the influence of the arc of the tail wheel, there is a slope on the belt. When the material falls at this position, a large amount of material will still splash or slide down, resulting in low cleaning efficiency; (2) The cleaning area is small. The material that can be cleaned by the circular scraper is limited to the width of the scraper, generally not exceeding 300mm. For a tail of more than 2m, the cleaning range is very limited. A large amount of material will still accumulate at the tail position outside the range; (3) It is easy to block the material because the opening area is small. If there is material agglomeration, the cleaning port may be blocked, and the problem of material blockage at the tail of the machine still exists. Utility Model Content
