Description

Technical Field

[0001] The invention relates to the field of conveyors, and in particular to a dust cover structure for a belt conveyor. Background Art

[0002] A conveyor is a machine that evenly transports bulk materials or packaged goods from the loading point to the unloading point along a certain route in a continuous manner. Conveyors can be widely used in industrial fields such as mining, metallurgy, building materials, chemicals, electricity, food processing, etc., in coal mines, metal mines, steel enterprises, ports, and cement plants. Conveyors may be affected by various environmental factors during use, and dust covers are usually required to reduce the impact on transportation. There is a lot of dust in the environment, and long-term accumulation of dust will affect the stability of the conveyor's transportation and the life of the conveyor. At present, there are two main structures of conveyor dust cover structures in the industry: the first is to use a guide trough to prevent dust, and the second is to use a rain cover to prevent dust, but both structures have shortcomings. The first method is to use a material guide trough to prevent dust. It is not only heavy in structure and costly, but also inconvenient to replace the lower material guide trough rollers at a later time. The second method is to use a rain cover to prevent dust. It covers the entire upper roller of the output machine. When the belt conveyor's belt deviation machine rollers are found to be damaged during inspection, it is difficult to remove the rain cover and replace the rollers. In addition, its large size takes up a lot of space. Summary of the invention

[0003] The object of the present invention is to provide a dust cover structure for a belt conveyor.

[0004] To solve the above problems, the technical solution of the present invention is:

[0005] A belt conveyor dust cover structure includes a conveyor belt, wherein a plurality of rollers are arranged at the bottom of the conveyor belt along the length direction of the conveyor belt; sealing cover frames are installed on both sides of the rollers, and the sealing cover frames are connected to lightweight sealing covers arranged directly above the conveyor belt; L-shaped elastic pressure plates are connected on both sides of the lightweight sealing cover, and the elastic pressure plates are in close contact with the conveyor belt.

[0006] As a further improvement, the sealing cover frame includes a vertical rod, the vertical rod is connected to a bending rod in the shape of an inverted "√", and the end of the bending rod is fixedly connected to the side of the L-shaped elastic pressure plate.

[0007] As a further improvement, the tilting rod is welded and fixed with a connecting plate, and the connecting plate is detachably connected to the lightweight sealing cover and the elastic pressure plate by bolts.

[0008] As a further improvement, the elastic pressing plate is a rubber elastic pressing plate.

[0009] As a further improvement, the lightweight sealing cover is a corrugated color steel plate.

[0010] As a further improvement, the lightweight sealing cover is arc-shaped.

[0011] As a further improvement, the roller is installed on a roller frame, and the roller frame and the sealing cover frame are both fixed on the middle frame of the conveyor.

[0012] Advantages of the present invention:

[0013] The dust cover of the present invention is located directly above the conveyor belt and does not cover the relevant structure of the main roller, so it does not affect the inspection and replacement of the roller, and it occupies a small space and is easy to install. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the overall structure of the present invention;

[0015] Figure 2 It is a side structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below.

[0017] like Figure 1 and Figure 2 The dust cover structure of a belt conveyor shown in the figure includes a conveyor belt 1, rollers 2, a sealing cover frame 3, a vertical rod 31, a bending rod 32, a lightweight sealing cover, an elastic pressure plate 5 and a conveyor intermediate frame 6.

[0018] The bending rod 32 is in a "√" shape, the lightweight sealing cover is an arc-shaped corrugated color steel plate, and the elastic pressing plate 5 is a rubber elastic pressing plate. The roller 2 is installed on the roller frame 21, and the roller frame 21 and the sealing cover frame 3 are both fixed on the conveyor intermediate frame 6.

[0019] During installation, first use the corrugated color steel plate to press into an arch as a lightweight sealing cover. In order to fix the lightweight sealing cover, a sealing cover frame 3 needs to be set. The sealing cover frame 3 includes a vertical rod 31 and a bending rod 32. The ends of the vertical rod 31 and the bending rod 32 are connected to the lightweight sealing cover with bolts 2 for easy disassembly and assembly. The other end is connected to one end of the vertical rod 31 by bolts 2 to facilitate the removal of the lightweight sealing cover to replace the roller. The other end of the vertical rod 31 is fixed to the middle frame of the conveyor. Because there is a gap between the lightweight sealing cover and the conveyor belt, in order to suppress the dust from overflowing from this gap, a sealing rubber plate needs to be set to block this gap. The sealing rubber plate is fixed to the dustproof station by the sealing rubber plate pressure plate.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
