Description

A kind of broken coal petrography mechanism of more cutting dives of hydraulic cylinder rotation pendulum cutting
Technical field
The present invention relates to a kind of digging equipment field, especially a kind of more cutting disc break up coal of hydraulic cylinder rotation pendulum cutting Rock mechanism.
Background technique
In coal industry programmatic document《About several opinions for promoting coal industry to develop in a healthy way》In, in national coal In industrial science technology conference and in the coal industry the policy of construction adjustment of National Development and Reform Committee's appearance, it is large-scale to be directed to development The contents such as coal underground performing comprehensive coal mining equipment.Driving and back production are the important production links of coal production, and national policy is:It adopts Pick is laid equal stress on, and driving is leading.The speedy drivage of coal mine roadway is the key measures that coal mine guarantees mine stable high yield.Efficient machine Toolization driving is to guarantee that mine realizes the developing direction of one of necessary condition of high-yield and high-efficiency and tunnelling technology.China Most important road heading machinery is boom-type roadheader in coal road high efficient driving mode.Boom-type roadheader is collection cutting, shipment, row It the functions such as walks, operate in one, being mainly used for the Rock in Well, coal or alternate heading of cutting arbitrary shape section.Present state Interior development machine design is able to satisfy domestic demand substantially, but from international advanced technology there are also with a certain distance from.And domestic current rock Lane is constructed still based on drilling and blasting method, and driving of the heavy boom-type roadheader for large rock-gateway is under test in China. That there are safeties is low for big gun pick technology, tunnel it is secondary destroy, dust is big, driving speed is slow, the length of service is short, maintenance cost is high etc. asks Topic.Therefore, the boom-type roadheader that can be competent at cutting hard rock is badly in need of technological innovation.Cutterhead is the execution unit of development machine, Its performance superiority and inferiority, directly determines the economic benefit of coal mining.In order to accelerate the localization process of high efficient driving equipment, improve It is imperative to carry out structure design to cutterhead for coal petrography cutting efficiency.
