Description

The invention relates to equipment for the extraction of minerals, namely, coal miners, working from the bottomhole conveyor frame. Coal ksmbinas are known, including separate blocks, containing a cutting part with an executive body and a gear-rack mechanism of pschachi, with the blocks interconnected Jl). The disadvantage of these devices is that the combine has a considerable length and, in addition, the connection of the blocks on the end sides is not a sufficiently reliable SI. The coal combine is the closest to that proposed by the technical essence and achievable effect, including rotary gearboxes with cylindrical bearings, blocks of the feed mechanism and cutting parts with executive orgsha and electric motor 2. The disadvantage of this combine is that the connection of the blocks to the front sides causes a large length of the combine, preventing you from fitting it into the coal seam. The aim of the invention is to improve the efficiency of the combine with a complex gypsometry formation. This goal is achieved by the fact that in the coal core, which includes rotary gears with cylindrical bearings, blocks of the pschacha mechanism and cutting parts with actuators and an electric motor, cylindrical supports of the rotary gears are located in the blocks of the cutting parts and the feed mechanism, each of the blocks of the cutting part being connected with the block feed mechanism through the sleeves, clamps and half-rings, the latter of which are installed in the annular grooves made in the blocks. Figure 1 shows the proposed combine, a view in plan; figure 2 is a cross section aa in figure 1 the body of the combine; FIG. 3 shows the assembly 1 in FIG. 2 of the connection of the blocks of the housing; in FIG. 4, a kinematic diagram of a combine. The body of the combine consists of a block of the feed mechanism 1 and the blocks of the cutting parts 2 with the electric motor 3, connected by lateral sides by means of eccentric sleeves 4, clamps 5 and half-rings 6-8. Bushings 4 and clamps 5 have screw and thrust

parts, while the largest diameters of the latter are eccentric with respect to the axes of the joint. The eccentric diameters of the l retaining parts of the retainers 5 are located in similar bores 9 of the body of the block 1, and the sleeves 4 are located in annular bores in the lateral walls of the bodies of the blocks of the cutting parts 2 (figure 3). The eccentric sleeves 4 and latches 5 are fixed in the cases of blocks I and 2 by half rings 7 and 8. Half rings 6-8 are installed in annular grooves in socket 4, clamps 5 and in block 1 housing.

The feeder unit 1 will consist of a single case with two chambers, while the left chamber contains the power drive of the zevochny wheel or hydrodrivers of the chainless movement mechanism of the combine, and the right-hand unit has electrical units for adjusting the speed of movement and starting the electric motor 3 (phi4).

The blocks of the cutting parts 2 contain combine hydraulic equipment pumps with their drives and conical gears that provide torque transmission from the electric motor 3 to the screws 10 through rotary gear units 11 and 13, cylindrical bearings 12 and 13 of the rotary gear units 11 are placed in annular borings located on the ends of the side walls of the buildings of blocks 1 and 2 (figure 1).

The blocks of the cutting parts 2 are additionally connected to the block of the feed mechanism 1 by the pins 14, the sockets under which are located on the adjacent side walls of their bodies (figure 2).

The harvester is installed on the downhole conveyor 15 on two downhill skis 16 fortified on block 1 and on two downhole skis 17 fixed on blocks 2.

When assembling the combine, the swivel gearboxes 11 with the support 12 are mounted in the annular bores of the body of the unit 1. Then the blocks of the cutting parts 2, previously connected to the electric motor 3, are fixed to the side of the block 1 by means of the screw parts of the eccentric sleeves 4, clamps 5 and pins 14. In the process The assemblies of the support 13 of the rotary gear units 11 are placed in the corresponding annular bores located at the ends of the blocks 2.

When the combine is dismantled, the sleeve 4 due to the eccentricity of the stop part rotates in the opposite direction, and the retainer 5 on the contrary is kept from rotation by its eccentric stop part. Accordingly axial forces.

arising in their screw parts, are transmitted through semirings 7 and 8 on the block housings, which ensures their disconnection.

During the operation of the combine, the housing is vibrated, due to which the sleeve 4 can twist from the retainer 5, therefore, to exclude this phenomenon, half-rings 6 are installed in the annular grooves of the latter.

Due to the use of the proposed coal combine, the length of the body is reduced by 2-2.5 times due to the parallel arrangement of the blocks of the cutting parts with the electric motor relative to the Feeder unit and the placement of the supports of the rotary gear units; rigid attachment of the cutting part blocks with lateral sides to the side of the -mechshimama feed unit is carried out with pins, half-rings and eccentric bushings and clamps eliminating the opening of the joints, ensuring that the combine and conveyor elements work normally; the presence of half-rings, which ensure the interaction of the block housings with eccentric bushings and clamps, as well as the screw and thrust parts in the latter, the ability to assemble and disassemble the housing without the use of additional devices. andredag & aaK combine provides effective use of it with complex gypsum em | 1 and layer.
