MINING COMBINE OF CONTINUOUS ACTION WITH CUTTING FRAME

摘要

FIELD: mining.;SUBSTANCE: mining combine of continuous action is proposed, comprising a bearing frame having a front part, and a cutting frame installed on the bearing frame with the possibility of displacement back and forth relative to it. At the same time the cutting frame has the front part, and the combine additionally comprises a cutting drum installed as capable of rotation on the cutting frame and arranged near its front part. The combine also comprises a collecting head designed to collect mined minerals and installed as capable of rotation on the front part of the cutting frame, and a hydraulic cylinder designed for rotation and fixation of the collecting head relative to the cutting frame both in direction of lifting, and in direction of lowering. Besides, the combine comprises the first drilling base installed as capable of rotation on the front part of the bearing frrame, the second drilling base installed as capable of rotation on the front part of the bearing frame and arranged at the distance from the first drilling base, a hydraulic cylinder designed for rotation and fixation of the first drilling base relative to the bearing frame regardless of the second drilling base, and a hydraulic cylinder designed for rotation and fixation of the second drilling base relative to the bearing frame regardless of the first drilling base.;EFFECT: provision of a better support for a combine in process of cutting drum cut-in.;5 cl, 8 dwg
