Description

Technical Field

[0001] The utility model relates to the technical field of comprehensive mechanized mining equipment in coal mines, in particular to a chute of a scraper conveyor for a fully mechanized mining working face with a detachable bottom sealing plate combination. Background Art

[0002] In my country, coal transportation at coal mine faces relies almost entirely on scraper conveyors. Currently, scraper conveyors used in fully mechanized coal mining (fully mechanized) working faces primarily utilize a bottom-sealed, integral structure to meet the high demands for reliability and durability of the central trough. However, the central trough of these bottom-sealed, integral scraper conveyors is designed as a single piece. This means that when adding or removing troughs, the upper and lower chain interfaces must be opened to remove and replace the scraper chain. This process is relatively complex and has a long-term impact on production. Utility Model Content

[0003] The purpose of the utility model is to provide a chute with a combined structure as an adjusting chute. The design makes the bottom plate a detachable combination, avoids the tedious chain threading process, and realizes the fast and convenient replacement of the middle chute.

[0004] To achieve the above-mentioned purpose, the present application proposes a detachable bottom sealing plate combined fully mechanized mining face scraper conveyor chute, comprising:

[0005] The removable bottom sealing plate is a solid steel plate with internal thread holes and welding fixed positioning pins on its periphery;

[0006] The outer periphery of the scraper conveyor trough body is provided with bolt holes corresponding to the connecting and fixing inner thread holes and positioning pin holes corresponding to the positioning pin positions;

[0007] The bottom sealing plate and the trough body connecting structure is used to connect the detachable bottom sealing plate to the bottom of the scraper conveyor trough body.

[0008] Furthermore, the structural members connecting the bottom sealing plate and the trough body are bolts and anti-loosening washers matched with the connecting and fixing inner thread holes.

[0009] Furthermore, the removable bottom sealing plate is a rectangular steel plate, the size of which is the same as the bottom surface of the scraper conveyor trough body, and the four corners of the rectangular steel plate are pre-drilled with connecting and fixing internal thread holes, and positioning pins are welded.

[0010] Furthermore, the four corners of the scraper conveyor trough body are pre-drilled with bolt holes corresponding to the connecting and fixing internal thread holes and positioning pin holes corresponding to the positions of the positioning pins.

[0011] Furthermore, during assembly, the detachable bottom cover is first laid flat, and then the scraper conveyor trough body is lifted, the positioning pins are adjusted to align with the positioning pin holes of the trough body, and the scraper conveyor trough body is dropped.

[0012] Furthermore, the bolt passes through the anti-loosening gasket and the bolt hole and extends into the connecting and fixing inner thread hole. After the bolt is tightened, the bolt head is completely sunk into the bolt hole.

[0013] Furthermore, the chute of the scraper conveyor of the combined fully mechanized mining working face with a detachable bottom sealing plate is a middle trough.

[0014] Furthermore, when it is necessary to add, remove or replace the chutes, the bolts are removed, the scraper conveyor trough body is lifted and the detachable bottom sealing plate is pulled out.

[0015] The above technical solution adopted by the present invention has the following advantages over the prior art: the present invention uses a combined chute structure as the adjustment chute, and this design makes the bottom cover a detachable assembly. When the middle chute needs to be replaced, there is no need to disconnect the upper and lower chains. The replacement can be completed by simply separating and reassembling the two parts of the middle chute, thus avoiding the tedious chain threading process and achieving quick and convenient replacement of the middle chute.
