Problems solved by technology

"The non-uniform blade drum of the shearer fundamentally solves the problems of pick arrangement on the drum, low energy consumption of the drum and load fluctuation, but fails to fundamentally solve the problem of efficient loading of the drum. The new contradiction brought about is Its static balance is poor and it is inconvenient when the pick is replaced

Abstract

A coal cutter double blade dual-cylinder drum comprises an inner barrel, a connecting disc, an end plate, an end sic, cutting blades, a tooth base, an injector base, an outer barrel, a rib plate, a load blade, and a sealing plate, wherein the connecting disc, end plate and the inner barrel are welded together, the cutting blades are welded on the inner barrel, the tooth base and the injector base are welded on the end disc and the cutting blades, the load blade is welded on the outer barrel, the rib plate is welded between the cutting blades and the load blade, the sealing plate welds the edges of cutting blades and the load blade. The invention can improve stable balance of drum, improve load efficiency and reduce energy consumption or the like.

Description

technical field [0001] The invention relates to a device in the technical field of coal mining machinery, in particular to a double-blade double-cylinder drum for a coal shearer. Background technique [0002] At present, the structural features of shearer drums at home and abroad mainly include the following points: the blades are uniformly distributed in the circumferential direction of the drum hub; the number of teeth on each section of the blade picks is usually less than the number of blades on the drum. The most common is the three-headed one-tooth roller; the blade pick is installed perpendicular to the roller axis in the radial direction of the roller, which is called 0° teeth; the loading of the roller also depends on the cutting blade welded with the tooth seat. Based on these characteristics, the overlapping of the blade picks and end disc picks of the drum is inevitable, which will easily cause vibration during work and poor ability to resist impact, leading to e...
