Coal mining and transporting integrated machine

Abstract

The invention discloses a coal mining and transporting integrated machine. The coal mining and transporting integrated machine comprises a machine frame, wherein the machine frame is connected with a power device, a bottom plate and a baffle are arranged on the machine frame, the bottom plate is horizontally arranged, a drive sprocket shaft and a driven sprocket shaft are vertically arranged on the bottom plate, the drive sprocket shaft is driven to rotate by a driving motor through a speed reducer, and the drive sprocket shaft is coaxially fixedly connected with a drive sprocket; the driven sprocket shaft is fixedly connected to the bottom plate, and the driven sprocket shaft is coaxially connected with a driven sprocket in a rotating way; the drive sprocket is connected with the driven sprocket by a chain, chain plates are fixedly connected to the links of the chain, at least one row of coal blocking teeth at a preset interval is formed in the length direction of each chain plate, and the coal blocking teeth on the adjacent chain plates are staggered with each other; the baffle is arranged between the two linear running sections of the chain, and is arranged in the length direction of the work surface. The coal mining and transporting integrated machine has the beneficial effects that coal mining and transporting are simultaneously finished by the same facility, the mechanical degree of coal bed excavation is high, the recovery rate is high, and the coal mining efficiency is high; convenient assembly, disassembly, maintenance and repair are realized.

Description

technical field [0001] The patent of the present invention relates to a coal seam mining facility, in particular to an integrated coal mining and transporting machine. Background technique [0002] my country is rich in coal resources, with a large amount of storage and a variety of occurrences. According to the division of coal seam thickness in my country, the thickness of 0.8 ~ 1.3m belongs to thin coal seam, and the thickness of less than 0.8m belongs to extremely thin coal seam. In my country's coal reserves, the recoverable reserves of thin coal seams are about 6 billion tons, accounting for about 20% of the country's total coal reserves. %. However, the output of thin coal seams only accounts for 10.4% of the country's total coal output, and this proportion is still showing a gradual downward trend. The main reasons are the low degree of mechanization of coal mining, low yield and efficiency of working face, high excavation rate, high mining cost and high labor inten...

AI Technical Summary

Problems solved by technology

The main reasons are that the degree of mechanization of coal mining is low, the unit yield and efficiency of the working face are low, the excavation rate is high, the mining cost is high, and the labor intensity of workers is high.

However, with the reduction of coal resources, many coal mines with extremely thin coal seam geological conditions have begun to mine. Under such conditions, the labor intensity of workers is extremely high and the working environment is very harsh. How to realize efficient and safe mining of extremely thin coal seams is a must for many coal mine technicians in Chongqing. The problem

The most advanced technology for mining thin and extremely thin coal seams is unmanned mining. At present, unmanned mining equipment includes coal plows, drum shearers, and drilling coal mining, but such equipment consumes a lot of energy and is bulky. It is not suitable for coal mining face with extremely thin coal seam below 0.5m
