Abstract

The invention relates to mining machines for extracting coal from steep formations and can be used to increase the reliability of the combine. An adjustable drum of the actuator is located in front of the drive gear housing on a pivot arm, the housing of which is fixed to the rolling bearings 11 and 12 in the cantilever portion 6 of the drive gear, the drive end of the shaft 15 of the second. (- .;;

Description

the drum is placed inside the handle housing coaxially with its supports 11 and 12 and is kinematically connected to the gear box 13, mounted on the axle of the carrier cover 5 of the console part of the drive gear, with the possibility of transmitting rotation to the regulator

the drum to be pulled from gear 17,

tinted on the shaft of the second drum in the area between the supports 11 and 12 of the handle body. The proposed technical solution allows to eliminate the emergency nodes of the hull supports and kinematic links in the design of the combine, which achieves the delivered

The invention relates to mining equipment for the mechanization of cleaning operations when mining coal on steep and steeply inclined bed seams.

The purpose of the invention is to increase the reliability of the combine by eliminating the above disadvantages.

In FIG. 1 shows a harvester, side view; in FIG. 2 - harvester, top view; in FIG. 3 is a section AA in FIG. 1, along the bores of the cantilever part of the drive gearbox with kinematic elements and supports of the handle and the second drum; in FIG. 4 is a kinematic diagram of a box gear interface assembly with a handle support and a second shaft.

The coal processor consists of a gearbox 1 of the actuator drive, an actuator including a cutting drum 2 fixed in the console part of the gearbox and a cutting drum 3 fixed on the rotary arm 4, the bearing cover 5 of the console part of the gearbox 6, engine 7, hitch 8, adjustment cylinder 9 the position of the drum 3, the housing 10 of the rotary arm with the rolling bearings 11 and 12, the box gear 13 with the support 14, the shaft 15 of the second drum with the supporting elements 16, the gear 17 transmitting rotation to an adjustable speed uschy drum, the carrier spigot 18 of the lid 5 and the drive gear 1.9 boiling rotated box-like gear 13..

During the operation of the harvester in complex formation hypsometry, the cutting drum 3 mounted on the pivot arm 4 due to the hydraulic cylinder 9 has the ability to change its position in terms of the thickness of the removed formation, from the soil to the roof of the formation, regardless of their bedding conditions, which ensures the extraction of coal in the required direction and forms a pit for passage of the combine body. Drum 2 in this case is auxiliary and processes the remaining irregularities in the roof or in the soil of the formation.

When swinging, the housing of the pivot arm rotates freely on the rolling bearings 11 and 12, made for example on ball bearings. Supports are in

abundant lubrication medium and reliably protected from the ingress of coal mines from the external environment. In the process, the rotation to the cutting drums is transmitted from the box gear 13 directly through the shaft 15 to the second drum 2 and through the gear 17 to the adjustable drum 3. The shaft 15 together with the drum 2 is axially fixed on the bearing bearings 16 and movably through the box gear 13 on the bearing support 14 mounted on the axle 18 of the bearing cover 5 of the console part b of the drive gear of the actuator, and the transmission

rotation to the box gear 13 from the gearbox 1 of the actuator drive is carried out through the gear 19.

The proposed technical solutions eliminate all the disadvantages of the prototypes, eliminate all negative phenomena during operation of the combine, which significantly increases the reliability of its operation in formations with complex bed hypsometry, and this allows us to expand the field of mechanization of sewage treatment in coal mining and increase labor productivity.
