Opencast coal mine continuous transport walking crusher

Abstract

The invention belongs to the technical field of transport equipment of an open pit coal mine, and particularly relates to a continuous walking type transport crushing machine of an open pit coal mine, which is used for solving the problem of existing open mining equipment. A receiving part, a main rack and a discharging part main body are all of a welded groove-shaped structure, so that an upper chain channel and a lower chain channel are formed, and are hinged together by virtue of a pin roll to form a coal conveying chain channel of the whole equipment, a scraper chain is arranged in the coal conveying chain channel and penetrates through the whole coal conveying chain channel, the upper chain channel is provided with a chain pressing block, a transport driving chain wheel and a tail guide wheel are respectively arranged at two ends of the scraper chain and are meshed and linked with the scraper chain, the scraper chain drives a chain wheel shaft to be linked with a left transport driving part and a right transport driving part which are arranged at the left side and the right side, and the left transport driving part and the right transport driving part are respectively provided with a transport driving part protecting cover. According to the continuous walking type transport crushing machine, a truck transporting link is eliminated, the transport cost is lowered, the equipment investment is reduced, the production capability and the production efficiency are improved, the cost of per ton coal is lowered, and the environmental-friendly mining of coal is realized.

Description

technical field [0001] The invention belongs to the technical field of transportation equipment for open-pit coal mines, and in particular relates to a continuous-transport walking crusher for open-pit coal mines. Background technique [0002] Open-pit coal mining has the characteristics of safety, high efficiency, easy reclamation, high recovery rate and low cost. my country is rich in coal resources available for open-pit mining, and the reserves suitable for open-pit mining are about 64.1 billion tons. At present, the open-pit coal mining in my country is usually dominated by the mining process of "single bucket excavator-truck-crushing station-belt conveyor", that is, the single-bucket excavator is arranged The type conveyor is arranged outside the stope. The coal mined by the single bucket excavator is first loaded into the truck, and then the truck transports the coal to the fixed crushing station for crushing. After crushing, it is unloaded into the belt conveyor and ...

Problems solved by technology

The main equipment of this intermittent mining process relies on imports. The truck passage covers a large area, and the movement of the centralized crushing station is difficult and time-consuming. Not only does it require a lot of initial investment, but the coal mining efficiency is low and the safety level is poor; Large consumption, high maintenance costs, high unit transportation costs, and serious environmental pollution make its mining costs remain high and economic benefits low, especially the current soaring fuel prices, which have a greater impact on the long-term development of mining areas

At the same time, due to the sharp increase in the cost of using a single-bucket excavator to mine thinner coal seams, most open-pit coal mines will discard the thin coal seams along with the stripping of rocks, resulting in a waste of national resources
