Description

one

The invention relates to mining and is intended to mechanize the destruction and extraction of minerals, mainly coal.

Known drum r. Residens in organs with a vertical axis of rotation, including a drum made of sliding and non-sliding parts, and a gearbox.

The purpose of the invention is to improve the reliability of the cutting body in the work

This is achieved by the fact that the gearbox housing is provided with a guide, and on the non-sliding part of the drum the ring interacting with the guide is hinged.

The drawing schematically shows the proposed drum cutting body about

It consists of a gear wheel I connected to a non-rising baraoan 2, to which a ring 4 is connected via two half-axles 5. m gearbox. The gear wheel I and the non-exhausting drum 2 rigidly connected with it are seated on the bearings 7, mounted on the gearbox housing В, In the lower part of the cutting body on the bearings 9, mounted on the gearbox housing 8, the cutting disk 10 with R. an elongated hub with internal splines, in which is placed equipped with external splines in l II,

5 rigidly connected to the extendable b, arabano, m 12 and movably - with the sliding element of the slotted hydraulic jack of the sliding frame 15 spaced AO: M bearing 1,

0The cutting body works as follows.

The gear I and the non-sliding drum 2 rigidly connected with it receive rotation from the gear of the reducer. Ring, Hinged

connected to the non-extendable drum by means of the half-axles 3, sets in motion the articulated fists 5 placed on it, which, resting with their lower planes on the inclined guide 6, slides along it. With its movement cutting

The teeth, placed on the hinge fists 5, process the bottom section, which is not clipped by the lower cutting disc 10 and the upper drums 2 and 12, and the hinge fists actively unload the coal from the destruction zone of the bottom. During its rotation, the non-rising drum 2, by means of the blades of its housing, which are included in the grooves of the casing of the sliding drum 12, rotates it, and the latter transmits the rotation to the lower cutting disc 10 through the spline shaft 11.
