Heading machine body integrated with scraper conveying device

Abstract

The invention belongs to the technical field of mine heading equipment, and particularly relates to a heading machine body integrated with a scraper conveying device. According to the heading machine body, the machine body and the scraper conveying device are integrally designed, so that the requirement of the heading machine on the width of a roadway is reduced; a front rack, a middle rack and a machine tail part which are connected in sequence are arranged on the machine body; an upper chain groove of the front rack is connected with a full-surrounding chain way which can be independently detached, and the front end of a lower chain groove of the front rack is connected with a guide chain way I and a guide chain way II which are symmetrically arranged; the upper chain groove of the middle rack is connected with a half-surrounded chain way which can be independently detached, the upper chain groove and the lower chain groove of the machine tail part are provided with fixed chain ways which are integrally connected with the upper chain groove and the lower chain groove of the machine tail part, and scraper chains are wound on the fixed chain way, the half-surrounded chain way, the full-surrounded chain way, the guide chain way I and the guide chain way II; and a driving device for driving the scraper chain to rotate is arranged below the tail part of the machine tail part. The requirement of the heading machine for the width of a roadway is reduced; and the replacement is convenient, and the later maintenance cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of mine excavation equipment, and in particular relates to an excavation machine body integrated with a scraper conveying device. Background technique [0002] At present, in the design of the roadheader, the frame and the scraper conveyor generally adopt a split type, and the scraper conveyor is a complete device inserted in the middle of the roadheader frame, which is simple to connect and easy to replace. [0003] With the multi-functional development of the roadheader, the roadheader integrates more and more functions such as drilling and anchoring. However, due to the influence of the excavation cost, it is difficult to increase the width of the roadway to adapt to the width of the roadheader. Most of the roadways cannot adopt more advanced comprehensive mechanized excavation equipment due to the width limitation. [0004] On the other hand, as the roadheader design technology becomes more mature, and ...

Problems solved by technology

[0003] With the multi-functional development of the roadheader, the roadheader integrates more and more functions such as drilling and anchoring. However, due to the influence of the excavation cost, it is difficult to increase the width of the roadway to adapt to the width of the roadheader. Most roadways cannot use more advanced comprehensive mechanized excavation equipment due to width limitations

[0004] On the other hand, as the roadheader design technology becomes more mature, and the use experience becomes more and more abundant, the scraper conveyor can fully meet the non-damage use during the overhaul period, and the convenience of replacement in the application process cannot be reflected. Therefore, From the consideration of reducing the manufacturing cost of the roadheader, it is possible to explore the use of a new scraper conveyor structure to improve the market competitiveness of the roadheader products
