Problems solved by technology

Drilling and blasting will cause great pollution to the environment. At the same time, the mined coal is large and needs to be transported to the mobile crushing station for crushing, which increases the cost per ton of coal
[0003] There is a drum-type open-pit continuous coal miner used for mining thin coal seams in open-pit coal mines. The mined coal is unloaded into trucks and transported away through its own scraper machine and belt conveyor. This coal mining method is still an intermittent method. Advanced coal mining technology, low production efficiency
Moreover, the traveling of the drum type surface continuous miner is driven by hydraulic pressure, which has poor overload capacity and low transmission efficiency
In addition, when the drum type surface continuous miner cuts coal, because there is no coal wall on one side, the cut coal falls far away and cannot completely fall on the loading part, so the coal loading effect is poor.

Embodiment Construction

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0034] This embodiment provides an electrically driven crawler walking type surface continuous miner, see figure 1 with figure 2 , the shearer mainly includes a cutting part 1, a loading part 13, a conveying part 6, a traveling part 10, a main frame 15, a cab 2, and a cable winding device 5. Its walking adopts 690V AC frequency conversion speed regulation electric traction system, which can meet the requirements of fast mobilization, frequent start and stop, reversing and cutting feed force. And it has the advantages of wide speed range, large starting torque, strong overload capacity, etc. At the same time, the walking AC frequency conversion motor and cutting motor are designed as a closed-loop automatic control system, and the walking AC frequency conversion ...

Abstract

The invention discloses an electric-driven track travelling type open-air continuous coal cutter. The overall coal cutter is composed of main parts such as a cutting part, a loading part, a conveyingpart, a travelling part, a main rack, a cab and a cable coiling device, can be matched with a scraping plate continuous transporting system or a belt-type continuous transporting system to be used forachieving continuous mining of an open-pit coal mine thin coal seam, and can also serve as coal mining equipment to be used independently, and mined coal does not need to be broken independently.

Description

technical field [0001] The invention relates to the technical field of design and manufacture of mechanical equipment in open-pit coal mines, in particular to an electric-driven crawler-type open-pit continuous coal miner. Background technique [0002] At present, the mining of thin coal seams in open-pit coal mines is the same as the mining of thick coal seams, using a coal mining process of blasting loosening-front loading machine excavation-truck transportation. Drilling and blasting will cause great pollution to the environment. At the same time, the mined coal is large and needs to be transported to the mobile crushing station for crushing, which increases the cost per ton of coal. [0003] There is a drum-type open-pit continuous coal miner used for mining thin coal seams in open-pit coal mines. The mined coal is unloaded into trucks and transported away through its own scraper machine and belt conveyor. This coal mining method is still an intermittent method. Advance...
