Scraper conveyer for heading machine

Abstract

A scraper conveyer for a heading machine belongs to the technical field of scraper conveyors and comprises a machine head, a conveying groove, a machine tail and a scraper chain, a swing pin with a vertical axis is arranged at the end of the machine head, the conveying groove comprises a machine head connecting groove, a transition groove and a middle groove which are sequentially connected, and two ends of the swing pin are connected with the machine head connecting groove. The machine head can transversely swing around the axis of the swing pin relative to the machine head connecting groove, so that the discharging end of the machine head can flexibly swing and be aligned with the feeding end of the transfer equipment in time. The conveying groove further comprises a passive hinged conveying groove, one end of the passive hinged conveying groove is connected with the middle groove, the other end of the passive hinged conveying groove is connected with the machine tail, and a longitudinal and transverse bidirectional swing mechanism is arranged in the passive hinged conveying groove. The machine tail can transversely swing or longitudinally swing relative to the middle groove through the longitudinal and transverse two-way swing mechanism so as to carry out loading along with movement of a cutting head of the heading machine in time, continuous adjustment of the material loading position and the material unloading position is achieved, and the material conveying efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of scraper conveyors, and in particular relates to a scraper conveyor for roadheaders. Background technique [0002] For the excavation of coal roadways, crawler-type roadheaders are traditionally used. The roadheaders are also equipped with conveying equipment that meets certain functions, but the conveying equipment must be used in conjunction with continuous miners and bolters to complete the material. The transshipment has the disadvantages of many equipment interfaces, many times of transshipment, long total supporting length, and unreliable support. At present, the scraper conveyor is used to complete the transportation of materials during the excavation process of the full-section rectangular roadheader coal mine roadway. The roadheader equipped with the scraper conveyor can realize the full-section rectangular roadway at one time, continuous and rapid excavation, and advance the bolting unit Tempora...

AI Technical Summary

Problems solved by technology

The existing scraper conveyor tail, conveying trough and machine head are fixedly connected, that is, the machine tail for material loading and the machine head for material unloading cannot move, so that the loading end of the machine tail cannot follow the cutting head of the roadheader in time The unloading end of the machine head cannot be aligned with the feeding end of the reloading equipment for unloading in time, resulting in low material transportation efficiency
