The invention relates to mining, and in particular to machines for mechanization of extraction of minerals in mines.

Known coal combines firm "Femur"containing feeders, zlektrooborudovaniya gearboxes, actuators, wiper device (W. Glückauf, September, No. 3, 2001, p.31).

In these harvesters rotary gearboxes fitted with eyelets located in the region of the axis of rotation. However, the lugs are located in housings of rotary gears with only one hand on the bottom. Therefore, the harvester must be equipped with two housings of the rotary gear (right and left), that would require making two different buildings and two, therefore, different models for castings and, accordingly, adjustment of the equipment for processing two buildings.

Closest to the proposed technical solution is Shearer containing the feed mechanism, the electronic unit, the rotary gears each case which is made symmetrical relative to the longitudinal axis and provided with lugs, Executive bodies, a wiper device, hydraulic equipment (RF Patent No. 2059808, Cle 21 27/02,1996).

However, the prototype has the disadvantage that the installation of the cylinder of rotation of the gear of the Executive body is only possible in the upper position, i.e. only on the turning gear. When the environment of the bracket and cylinder rotate the Executive body at the bottom of the harvester overlaps the loading space and greatly reduced loading the broken coal on the conveyor in particular at the lower location the Executive body is almost completely covered cargo space.

The objective of the invention is to provide interchangeability of rotary gears and providing a convenient arrangement of the cylinders rotate the Executive body on the bottom and top of the harvester, free loading the broken coal on the conveyor even when the lower location of the Executive body and the lower location of the cylinder of rotation of the Executive body.

The problem is solved due to the fact that in a mining combine, containing the feed mechanism, the electronic unit, the Executive bodies, a wiper device, hydraulic equipment, rotary gears each case which is made symmetrical relative to the longitudinal axis and provided with lugs arranged in the region of the axis of rotation of the rotary gear, respectively, two top and two bottom, and the top or bottom eyelets, depending on the location of the hydraulic cylinder on the harvester through the axes mounted on the bracket with eye fixed on the rod of cylinder rotation, the Executive body, while the position of the axis of the fastening rod of the cylinder defined by the axis of the bracket, and the distance from the axis of the fastening rod to the axis of rotation of the turning gear is half the stroke of the piston rod of the hydraulic cylinder.

Supply every what about the housing of the rotary gear lugs located near the axis of rotation of the rotary gear, respectively, two top and two bottom, is new and allows you to position the cylinders rotate Executive bodies at both the top and bottom of the harvester, providing easy loading the broken coal on the conveyor even when the lower location of the Executive body.

The fixation of the stem axis at a distance of 1/2 of the stroke of the piston rod of the hydraulic cylinder to the axis of rotation of the rotary gear has novelty. This allows for wyderka 1/2 turn stem to make the deviation of the first cylinder down from the horizontal position, and then upward to a horizontal position when wyderka 1/2 stroke of the rod. This feature allows you to exclude the execution of niches in buildings mechanisms filing under the cylinder, and hence tastebook it from the flow of coal, particularly at the lower location of the cylinders on the harvester.

Figure 1 shows Shearer, General view; figure 2 is a view of the rotary gear with the cylinder, screw and Stripping device.

Shearer includes the feeders 1 and 2, the electronic unit 3, the rotary gears 4 and 5, the Executive bodies 6 and 7, a wiper device 8 and 9, hydraulic equipment 10 and the irrigation device 11.

Rotary gear consists of a housing 12, with two lugs 13 and 14, located in Paradise is not the axis of rotation of the gearbox at the top of the housing, and the two lugs 15 and 16 at the bottom of the housing, the bracket 17, which axes 18 and 19 is connected with the housing of the rotary gear and the axis 20 with the hydraulic cylinder 21. The hydraulic cylinder 21 axis 22 is connected to the housing of the feeder at the bottom and top, depending on the location of the RAM on the processor.

Swivel reducer equipped motor 23, which is located in a recess of the housing 12, and a drive rotation of the shield 24 located on the upper part of the housing, through which the pins 25 that are built into the panels, performs rotation clockwise or counterclockwise.

Before installing on the Shearer, the assembling of the right (left) rotary gears 4 and 5, a day what does the following: using two identical housing 12 installing the shafts with gears (not shown in figure 2), bearings, caps with gaskets and bolts.

Install the drive rotation of the shield 24.

The difference in the Assembly of the right and left turning of the gears is that the fixing of the drive rotation of the shield to the right of the turning gear is made on the upper part of the body, and for the left turning gear on the lower part of the body. Supply hydrologically to drive hydraulic motors rotate the shield to the left of the turning gear will be mirrored with respect to the right to the rotary gear. Also for other btes is key bracket 17 will have a mirror.

Collected rotary gears 4, 5 together with the bracket 17 mounted with the feeders 1 and 2.

Shearer, comprising a feed mechanism, the electronic unit, the rotary gears each case which is made symmetrical relative to the longitudinal axis and provided with lugs, Executive bodies, a wiper device, hydraulic equipment, characterized in that the lugs are located in the region of the axis of rotation of the rotary gear, with two top and two bottom, and the top or bottom eyelets depending on the location of the hydraulic cylinder on the harvester through the axes mounted on the bracket with eye fixed on the rod of cylinder rotation, the Executive body, the distance from the axis of the fastening rod to the axis of rotation of the turning gear is equal to 1/2 of the stroke of the piston rod of the hydraulic cylinder.
