Abstract

The invention relates to equipment for mechanizing coal excavation and enhances reliability by maintaining a constant area of contact between the claws and the guide. The feed mechanism includes hydraulic jacks (HD) 1, pivotally mounted on the body of the combine 2. The rods 3 of the HDD I are connected by spheres 4 to forks 5, each of which is connected to grips made in the form of two shoulders S / // (L: o eo

gov (P) 9 and 10. By means of axes 11 P 9 and 10 are connected with the brackets 12 of the gripping housing 6, and axes 13 with the brackets of the 14 profile slats (W) 15. The PP 15 is mounted on the guide rail 16 fixed to conveyor 17. When supplying ddokkosti in one of the DG 1, its rod 3 is drawn in and through the sphere 4 raises the plug 5, which, lifting, turns P 9 and 10 relative to the bracket

The invention relates to the mining industry and is intended for the movement of shearers.

The aim of the invention is to increase reliability by maintaining the contact area of the grips with the guide.

Figure 1 shows the proposed feed mechanism; figure 2 is a view of And figure 1; on fig.Z - section bb in fig. 2

MexaroisM feed shearer contains hydraulic jacks 1, pivotally mounted on the body of the combine 2, the rods 3 of which are connected by spheres 4 to forks 5 installed in the body 6 of the grippers. The insert 5 is pivotally connected to the grippers 7 and 8, displaced one relative to the other in a vertical plane to a height h and made in the form of two shoulders 9 and 10. The latter are connected by axles 11 to the grips 12 of the gripping body 6 and by means of axes 13 to kroshpteyny 14 profile bars 5. The profile bars 15 of the gripping housing 6 are mounted on the profile guide rail 16. mounted on the face conveyor 17.

The feeder shearer works as follows.

When fluid is supplied to one of the hydraulic jacks 1, its rod 3 is retracted, lifting as a result of the appearance of a vertical P constituting usli P (FIG. 3) by means of sphere 4, plug 5, while plug 5, raising

on 12 korpus.6 capture. The PP 15 of the McUOTCH is attached to the rail 16. The hull of the combine 2 moves relative to the conveyor 17. The stem 3 of the second DG 1 extends by moving the fork 5 and removes the rail 16 and the PP 15 by shifting P 9 and 10 from the engagement. planes, PP 15 move equidistantly to the rail 16, which does not cause skews of PP 15 relative to the rail. 3 il.

c, rotate the double-arm levers 9 and 10 by means of the axles I1 relative to the brackets 12 of the gripping body 6. As a result, by means of the axes 13 fixed by the brackets 14, the profile bars 15 are pressed against the profile guide rail 6. Later on, when the rod 3 is pulled the hydraulic cylinder I, as a result of the interaction of the corrugated surface of the profile bars 15 with the corrugated surfaces of the profile guide rail 16, moves the body of the combine 2 relative to the bottomhole conveyor 17. At the same time, under the influence of liquid to 3 of the second hydraulic cylinder i, the force P moves the fork 5 under the influence of the vertical component Pg by means of the sphere 4 downwards. At the same time, the two shoulders levers 9 and 10, turning relative to the arms 12 of the gripper body 6 on the axles 11, remove from engagement the profile direction of the rack 16 and the profile strips 15, which as a result of displacement in the vertical plane to the height h move the equidistant profile the guide rail 16, without causing distortions and unequal displacements of the profile bars 15 relative to the guide rail 16. Subsequently, when the stem 3 of this hydraulic cylinder 1 rotates, the gripping body 6 slides relative to the profile guide slats 16 until the full extension of the rod 3 of the hydraulic cylinder 1, i.e. bringing it back to its original state to complete the following

walking cycle. Then the cycle repeats. The oscillations of the hull of the harvester 2 as a result of its operation during the destruction of the coal seam by the combine and the loading of the destroyed part of it onto the bottomhole conveyor 7 are not transmitted to the gripper body 6 and the grippers 7 and 8 by connecting rods 3 of hydraulic jacks 1 with forks 3 by spheres 4.
