Integrally-cast transition groove for scraping machine

Abstract

The invention discloses an integrally-cast transition groove for a scraping machine, and relates to the field of scraping machine accessories. The integrally-cast transition groove for the scraping machine comprises a first transition groove body and a second transition groove body, a first lingual plate is arranged at the upper end of the first transition groove body, upper wing plates are arranged on the two sides of the upper end of the first lingual plate correspondingly, reserved threaded holes are formed in the upper wing plates, a first sealing bottom plate is arranged at the lower endof the first transition groove body, a first chain way bottom plate is arranged in the middle of the first transition groove body, a first supporting frame is arranged between the first chain way bottom plate and the first sealing bottom plate, and first bolt connecting bases are fixedly installed on the outer surfaces of the two sides of the first transition groove body. According to the integrally-cast transition groove for the scraping machine, the easy-to-wear parts of the first transition groove body and the second transition groove body are all integrally cast and formed, so that a chainway is integrally cast without welding, the poor welding performance and generation of welding defects are avoided, and the overall strength is improved.

Description

technical field [0001] The invention relates to the field of scraper machine accessories, in particular to an integral casting transition groove for a scraper machine. Background technique [0002] Scraper conveyor is one of the main transportation equipment in coal mine. It consists of a transmission device, a machine head, a transition slot, a push beam, an elevated slot, a middle slot, a tail, a scraper chain and a baffle, etc. The main function of the transition groove is to make a smooth transition between the head of the scraper conveyor and the raised groove or the middle groove, so that the scraper can run smoothly in the transition groove. The transition trough is subject to pressure, tension, bending, impact, vibration, friction and corrosion during the working process. The transition trough is the most severely worn part of the scraper conveyor. [0003] In the prior art, the material of each part of the conventional transition groove is inconsistent. Since the ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the material of each part of the conventional transition groove is inconsistent. Since the wear of the bottom plate in the transition groove is the most serious, it is usually manufactured by cutting and blanking high-carbon wear-resistant plates. The performance and economy are generally cast by ZG30siMn with poor wear resistance and low tensile strength, and other link parts are manufactured by 16Mn plate cutting and blanking machine to ensure strength and welding performance

Most of the bottom plates in the transition groove are high-carbon wear-resistant plates, which cause a series of problems such as poor welding performance, high welding stress, easy welding of the middle plate, easy drop of the bottom cover plate, low connection strength, and poor wear resistance of the connection parts. , we propose an integral casting transition groove for scraper machine
