Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyors, in particular to an online deviation-correcting conveyor. Background Art

[0002] With the development of society, the industrial level of mankind is constantly improving. In the process of industrial production and transportation, it is inevitable to use various conveyors. As a conveying device in various coal industries, mining industries, construction cement industries, solid waste treatment industries, etc., conveyors are used in the process of conveying various materials to play the role of more uniform and convenient transportation of materials. In the prior art, the conveyor relies on the weight and friction of the material to stay on the conveyor belt and transport it forward with the belt. However, when the material is uneven and cannot fall in the middle of the belt, or the material deviates during the transportation process, the existing conveyor belt will inevitably deviate, causing the material transportation to stagnate, and it needs to be stopped for manual adjustment, which affects the transportation efficiency.

[0003] For example, the "scraper conveyor for coal mine production" disclosed in the Chinese patent literature has a publication number of CN214778574U, which includes a shell, a feed port is installed on the upper surface of one end of the shell, and multiple groups of buffer plates arranged in a staggered and inclined manner are installed in the barrel of the feed port, and a discharge port is installed on the lower surface of the other end of the shell. Active wheels and driven wheels are movably installed on both sides of the inner cavity of the shell, and a conveyor belt is wound between the active wheel and the driven wheel. Multiple groups of scrapers are evenly installed on the conveyor belt, and the lower surface of the conveyor belt contacts multiple groups of buffer support devices. The buffer support device is fixed in the shell through a mounting plate. The buffer support device includes a support column, a spring, a roller and a roller support. The spring is arranged inside the support column, and the roller support is slidably installed in the support column and abuts against the spring. The roller is in sliding contact with the conveyor belt. The disadvantage of this patent is that during the operation of the conveyor belt, the conveyor belt may deviate due to uneven materials, and the conveyor belt needs to be stopped for adjustment, which affects the conveying efficiency. Utility Model Content

[0004] The utility model aims to overcome the problem in the prior art that, in the process of conveying materials, the conveyor belt needs to be stopped for adjustment after deviation, which has a great impact on the conveying efficiency. An online deviation-correcting conveyor is provided, which can correct the conveyor belt deviation more quickly, thereby improving the conveying efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0033] Embodiment 2, as Figure 1-3 As shown, an online deviation-correcting conveyor includes a conveyor belt installed on a conveying platform 1. The conveying platform 1 is in a curved shape with a gradually decreasing height. The bottom of the conveying platform 1 is supported by a plurality of support columns of different heights.

[0034] The conveyor belt is provided with a motorized roller 2 and a driven roller 3 at both ends. A plurality of rollers are provided between the motorized roller 2 and the driven roller 3 along the length direction of the conveying platform 1, and the conveyor belt passes through the motorized roller 2, the rollers, and the driven roller 3 to transport materials.

Figure 2 The direction shown is used for explanation. A dustproof protective shell 7 is installed on the part of the screw rod 4 located on the left side of the left driven roller bracket 5. The dustproof protective shell 7 is fixed to the driven roller bracket 5 by bolt connection or welding. A non-through cavity on the left side is provided in the dustproof protective shell 7. The cavity is used to accommodate the left end of the screw rod 4 and provide a margin for the left and right movement of the screw rod 4. The screw rod 4 is located on the right side of the right driven roller bracket 5, and an elastic dustproof protective cover 8 is installed at the position between the driven roller bracket 5 and the rocker handle. The elastic dustproof protective cover 8 can be a bellows or other hollow structure with axial elasticity.
