Description

Technical Field

[0001] The utility model relates to the technical field of mining scraper conveyors, and specifically relates to an open skylight slot for a mining scraper conveyor. Background Art

[0002] The open skylight slot in a mining scraper conveyor is used to inspect the condition of the bottom chain and solve bottom chain faults. This design helps to maintain the normal operation of the conveyor. The conventional open skylight slot has a length of 1.5 meters and is usually composed of an open slot body and a movable slot side. This design allows operators to easily enter and operate when it is necessary to repair or replace the bottom chain.

[0003] The movable slot side is fixed to the open slot body on one side of the scraper plate by bolts. The operator needs to operate on the side of the scraper plate against the coal wall in order to disassemble and remove the movable scraper plate. Although this operation process is necessary, due to the narrow space on the side of the scraper plate against the coal wall, the operator faces space limitations when performing these tasks and needs to operate in an extremely limited space, which increases the complexity and difficulty of the operation. In addition, the coal mine working environment is often accompanied by dangerous factors such as dust and coal dust. There are relatively large safety risks for the operator to carry out maintenance work in such an environment, such as falling objects, equipment failures or other accidents. These risks pose a threat to the safety of the operator and affect the safe production of the coal mine. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an open skylight slot for a mining scraper conveyor, so as to solve the problem that in the actual use process, the operator needs to operate on the side of the scraper plate (against the coal wall) to remove the movable scraper plate, while the space on the side of the scraper plate (against the coal wall) is narrow and has great safety risks, which is not conducive to the safe production of the coal mine.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An open skylight slot for a mining scraper conveyor, including a left middle plate, a baffle slot side, an insertion plate assembly, a scraper plate slot side, and a right middle plate.

[0010] Preferably, rubber pads are provided at the contact ends of the plug board assembly with the left middle plate and the right middle plate to reduce wear and impact.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By providing concave grooves on the corresponding end faces of the left middle plate and the right middle plate, and designing the plug board as a convex extension part matching the concave groove, the convex extension part is in close contact with the concave groove. When an installation groove is provided on the baffle rib, first insert the first plug board and push it to the right so that the convex extension part of the first plug board is in close contact with the concave groove of the right middle plate. Subsequently, slidably install the second plug board on the sliding groove of the first plug board, and at the same time ensure that the other end of the second plug board is in close contact with the left middle plate. After installation, insert the positioning bolt through the preset installation hole and the linkage hole and fasten it with a nut to fix the plug board assembly. The opening groove body has a simple structure and is easy to produce. Both the baffle rib and the shovel board rib are processed from standard middle ribs without additional mold casting. The installation of the plug board assembly is convenient and the operation is simple. The plug board and the groove body are only connected by one positioning bolt, and the use safety is high. The plug board assembly can be drawn out from one side of the baffle rib, thus avoiding the staff from approaching the coal wall and reducing the operation risk. BRIEF DESCRIPTION OF THE DRAWINGS
