Transfer machine middle groove and transfer machine

Abstract

The invention provides a transfer machine middle groove which comprises a first baffle, a first groove ledge, a middle plate, a bottom plate, a second groove ledge and a second baffle, wherein the bottom plate and the middle plate are fixedly connected with the first groove ledge and the second groove ledge respectively; the middle plate is positioned above the bottom plate; and the first baffle and the second baffle are fixedly connected with the first groove ledge and the second groove ledge respectively. The transfer machine middle groove further comprises a first section, a second section and a third section, wherein the second section is positioned between the first section and the third section; both ends of the second section are fixedly connected with one end of the first section and one end of the third section; and the first section and the third section are mutually parallel straight sections, but are not positioned in the same straight line. The invention further provides a transfer machine. As the bent middle groove is adopted, the transfer machine middle groove can meet short distance bending requirements and bent section fixity requirements; and in addition, the width of a transport gate road is reduced when the unloading distance between a scraper conveyer head and the transfer machine is ensured, therefore, the support difficulty and tunneling cost of the transport gate road are reduced.

Description

Technical field [0001] The invention relates to the field of coal mining, and in particular to a middle slot of a transfer machine and a transfer machine containing the middle slot of the transfer machine. Background technique [0002] At present, as the intermediate transfer equipment of the mining and tunneling coal transportation system, the transfer machine is usually arranged in the transportation chute of the fully mechanized mining face. It is a heavy-duty scraper conveyor that can move longitudinally as a whole. Its length is small and easy to follow. The advancement of the coal mining face and the expansion and contraction of the belt conveyor move as a whole. [0003] The coal mining process of the double-stretch working face is suitable for the long-wall working face with larger length, which overcomes the limitation of the laying length of the scraper conveyor to a certain extent. The coal mining process includes: arranging two return air troughs and a common transport...

AI Technical Summary

Problems solved by technology

[0007] 1) The width of the transport channel is too wide, which not only increases the difficulty of supporting the channel, but also increases the cost of excavation;

[0008] 2) The horizontal direction adaptation angle of the connection between adjacent middle grooves is small, and the bending requirements of the reloading machine cannot be realized within a short distance

[0009] 3) When the transfer machine is advancing with the working face, it cannot guarantee the fixity of the bending section
