Bottom-opening type scraper conveyor and transition slot thereof

Abstract

The invention discloses a transition slot of a bottom-opening type scraper conveyor. Two sides of the bottom of the transition slot are provided with a first support plate used for supporting a scraper of a scraper conveyor; one end of the support plate close to a middle slot is provided with a downward bending part; the minimum distance between the bending part and a neighboring second support plate of the scraper thereof is larger than the maximum thickness of the scraper; when the scraper falls off a track, and moves to the position of the transition slot under the traction of a chain, the bending part arranged at the end part of the first support plate can prevent the scraper from entering the bottom of the first support plate; moreover, under the traction of the chain, the scraper can gradually climb to the upper surface of the first support plate and enter a running track at the front end of the transition slot; therefore, the scarper is prevented from entering the bottom of the first support plate to block the chain, and the operating safety of the scraper conveyor is improved; moreover, the structure is simpler. Besides, the invention also provides a bottom-opening type scraper conveyor comprising the transition slot.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a transition trough for an open-bottom scraper conveyor. In addition, the present invention also relates to an open bottom scraper conveyor comprising the above-mentioned transition groove. Background technique [0002] The scraper conveyor is a kind of mechanical equipment for transporting coal and other materials, and it is an indispensable main equipment in the modern coal mining industry. [0003] The scraper conveyor includes the traction power components of the head and / or tail, the transition groove, the middle groove, scraper 1 and chain 2, etc., the chain 2 is provided with several scrapers 1, and the chain 2 is connected to the traction power components, Under the action of the traction power part, the chain 2 drives the scraper 1 to move, and under the action of the scraper 1, it drives the coal and other materials in the chute of the scraper conveyor to move...

AI Technical Summary

Problems solved by technology

[0007] For the scraper conveyor with double-chain transmission, the working surface is complicated and uneven, and the scraper 1 may be stuck at the joint between the two middle grooves, which may cause the scraper 1 to tilt easily, resulting in falling off the road.

[0008] In the prior art, the support plate of the bottom scraper 1 of the transition tank is connected to the bottom support plate of the middle tank. Therefore, after the scraper 1 falls off the track, when the scraper conveyor continues to work, the scraper 1 that falls off the track It is easy to get stuck on the lower part of the bottom plate of the transition trough, and cannot return to the chain in front of the transition trough, which will cause the scraper conveyor to not work normally, or even break the chain.
