I The invention relates to the mechanization of underground coal excavation, and namely to the feeder cleaning machines,

The purpose of the invention is to reduce the dynamic loading of the feed mechanism.

FIG. 1 shows the rail of the feed combine; in FIG. 2 is a view A of FIG. one; in fig. 3 - I view B in FIG. one.

The rail 1 of the feed combine of the shearer is made in the form of a package of toothed plates 2, which contact with each other by protrusions 3 of the mating surfaces 4, and through axes 5 with elastic elements 6 is connected with the conveyor 7 through attachments 8. An asterisk interacts with the rail. 9 shearer.

Rake works as follows.

By rotating the sprocket 9 mechanism

6. At the same time, due to this displacement, the contact area of the teeth of the sprocket 9 and the rail 1 (Fig. 3) is significantly increased, as compared with the engagement of the oscillating asterisk 9 with the rail, which is made integral as usual (shown with a dashed line, fig. 3). At the same time thanks to the proposed implementation of the slats. 1 with mating surfaces 4, part of the energy of oscillations of the body 10 when it is operated together with an asterisk 9, both in the plane of the formation and in the frontal plane of the formation is dissipated during friction of the projections 3 of the attachment surfaces 4 and deformation of the elastic elements 6 of the axes 5. At a meeting of the cutting tool of the executive body of the shearer 10 with. solid inclusion or rock layer height of the fortress part of the energy from peak loads transmitted to the drive transmission

filing, the teeth of which interact 25 executive body and mechanism

with teeth of toothed plates 2, the shearer body 10 is moved, relative to the bottomhole conveyor 7, and fed to the bottom face. When the body of the combine 10 oscillates together with an asterisk 9 both in the plane of the reservoir and in the frontal plane of the reservoir, resulting from the formation on the executive body of the combine 10 of deterministic low-frequency oscillations of the load from the destruction of the coal massif and loading of its destroyed part, the part of the toothed plates 2 shifts the longitudinal direction by an amount proportional to the unit loads arising when the teeth of the starter 9 and the lath 1 are in contact due to the elastic deformations of the elastic element is dispersed by rubbing the priming surfaces 4 of the projections 3 of the pack of toothed plates 2 and the deformation of the elastic elements 6, the axes 5, of the suspension equipment 8.

Invention Formula The rake of the feed combine of the shearer, including sections connected to each other and with the conveyor, is due to the fact that, in order to reduce the dynamic loading of the feeder, each section of the rail is made in the form of a package of gear plates mounted on the mounted equipment by passing through gear plates of axes with elastic bushings located on them.
