The invention relates to mining machines, namely to the mountain harvesters for mined in short lavas (up to 50 metres).

Known harvester cleaning [1], comprising a housing with skis and placed in it the motor with a hydraulic pump, the feed mechanism of the harvester along the face, the carriage with the possibility of longitudinal movement through the chain circuit through the sprocket relative to the body combine with a locking device and the shaft with the brake device on the end of the shaft fixed two shoulders rotary gear with the screw.

Closest to the proposed invention to the technical essence and the achieved result is a harvester [2], comprising a housing with skis and placed in it the motor with a hydraulic pump, the feed mechanism of the harvester along the face, the carriage can be moved relative to the housing of the harvester with a locking device and the shaft with the brake device; at the end of the shaft fixed two shoulders rotary gear with a screw conveyor and its drive; to the neck of the bend of the shaft is connected to the cylinder of the rotation shaft and two shoulders of the rotary gear and telescopic hydraulic cylinder for moving the carriage.

The lack of harvesters [1 and 2] is that when working in their short faces it simultaneously to the same harvesters held with one hand or two, edge is m slaughter, ahead of production for future use. However, a certain position of the screw relative to the harvester and a goaf is not possible to provide the necessary rectangular transition from soil to develop its wall (Board)of manufacture. This transition is obtained by a radius equal to half the diameter of the screw and the mounting supports this generation is a need for additional manual work sample this transition.

Object of the invention is to enhance the functionality of the combine and increase its efficiency.

This problem is solved due to the fact that in a mining machine, comprising a housing with skis and placed in it the motor with a hydraulic pump, the feed mechanism of the harvester along the face, the carriage can be moved relative to the housing of the harvester through the telescopic cylinder retainer carriage and the shaft with the brake device and the cylinder rotation shaft, on the end of the shaft fixed two shoulders rotary gear with the auger and drive in the shoulder swivel reducer, which is screw drive, a built-in mechanism to perform a rotary movement about the longitudinal axis of that part of the shoulder, where is the screw with the drive.

Comparison of proposed clearing combine with prototype and similar solutions, known from the existing art, allows to establish its compliance with the patentability criteria of "novelty" and "inventive step".

The proposed solution combine of treatment is illustrated by drawings. Figure 1 shows Shearer (main view); figure 2 - top view figure 1 and figure 3 - position of the screw in the rotated view to finalize the pairing of soil and Board production.

Harvester cutter includes a housing 1 with the ski 2, placed in it the motor 3 with the hydraulic pump 4, driving the hydraulic motor 5 Shearer along the face through a gear wheel 6, the carriage 7 with the possibility of longitudinal movement relative to the body combine with a locking device 8 and the shaft 9, the hydraulic cylinder 10 to rotate the shaft 9 and raise or lower the two shoulders of the rotary gear 11 with the screw 12, an actuator 13 which is embedded in two shoulders rotary gear 11, the brake device 14 for fixing the shaft 9 and two shoulders of the rotary gear 11, in which the shoulders 15 and 16 are interconnected by a hinge 17 to lock the various mutual locations of the shoulders, and the mechanism 18 located on the shoulder 16 that allows you to perform a rotary movement about the longitudinal axis of that part of the shoulder where the screw 12 with the actuator 13.

Harvester works in the following way. The auger 12 ustanavli who is in operating position at the desired height relative to the ground or the roof of a coal seam by turning the shaft 9. For this purpose, the hydraulic cylinder 10, the piston rod which is fixed to the neck of the bend of the rotary shaft 9 by spreading or contraction of the hydraulic cylinder, carries out the rotation of the shaft while turning the two shoulders of the gearbox 11. The fixing system shaft 9 - two shoulders rotary gear 11 - screw 12 is achieved by a braking device 14 made in the form of a disk brake mounted on the shaft 9.

When the blasting of coal auger 12 should be in front of the body of the harvester, it provides the best conditions for loading the broken coal in the AFC. For this purpose, the carriage 7 must occupy one of the extreme positions on the housing 1 of the harvester. The moving carriage is telescopic hydraulic cylinder. The position of the carriage 7 relative to the housing 1 of the harvester is fixed a locking device 8. The harvester works on chelnokova scheme, i.e. the breaking of coal produced when moving it in both directions, it is therefore necessary at the ends of the lava to produce the turn of the screw 12 with two shoulders rotary gear 11 from one extreme position relative to the housing of the combine harvester in the other extreme position. Turn the rotary gear 11 and a screw 12 within the capacity of the coal seam must the shoulders 15 and 16 (see figure 1) turning gear to rotate relative to each other so that when they rotate relative to the shaft 9 auger is been earlier purchased within a coal seam. Upon rotation of the rotary gear is rectified, is fixed, is moved into position and a new cycle begins blasting coal.

For contouring output end face using the auger 12. Maneuvering the machine and moving the auger rotary gear 11, give the formulation of the desired parameters. However, at the transition from soil to Board production remains the so-called "dead zone", which is not selected by a screw at its normal position (see figure 1, the shaded sector a). For a sample of this transition is enabled mechanism 18 (for example, the actuator part-turn actuator [3, s, 187, RES, 77]) and it is the turn of the screw 90 degrees relative to the longitudinal axis of the shoulder 17, where the auger 12 and the actuator 13. This position of the screw allows you to handle so-called "dead zone" (see figure 3).

A technical advantage of the proposed clearing combine for short love is to enhance and increase its efficiency.

To enhance the functionality and efficiency achieved due to the fact that the shoulder swivel reducer, which are screw drive, a built-in mechanism to rotate about the longitudinal axis of that part of the shoulder, where the auger drive.
