The invention relates to an e-slag for mechanization under a high output grinder, namely, to the mechanism for feeding the shearer combines.

The purpose of the invention is twisting objectives and durability,

FIG. a schematic representation of the proposed supply mechanism of the shearer; in fig. 2 - the driving gear assembly.

The feed mechanism of the shearer includes a rotary body 1 mounted on a pin 2 in the bore 3 of the body of the combine 4, the input shaft 5 of which is connected to the hydraulic motor 6. The idler shaft 7 of the feed mechanism is connected to an asterisk 3 by means of gears 9 and iO, which have a spherical shape with a center at point O, which coincides with the turning point of the sprocket 8. The teeth of the aftermead interact with the fingers of the 1I rail 12j attached to the 13 V bottomhole conveyor The axial direction of the housing of the I feed mechanism is fixed by the sleeve 14.

The feed mechanism works as follows.

The input shaft 5 of the transmission of the feed mechanism, the drive, by rotation of the hydraulic motor 6, transmits the torque to the drive shaft 7 of the housing 1 of the feed mechanism, the sprocket 8 mounted on the drive hall 7 can be rotated relative to point O and associated with it in) gear wheels spherical forg F 9 and 10, rotating, interacts with, finger: mi 1 rack) 2 and peremetzlet combine body 4 relative to

In this case, as a result of the destruction of the combine of the Tolny massif by the executive bodies and the loading of the destroyed part B of the combine, the body of the combine 4 is affected by periodically changing its efforts, under the influence of which it carries out oscillatory movements in all planes. The oscillatory movements of the body of the combine 4 in the plane j perpendicular to the plane of the formation (t, e, in the frontal plane of power) are not transmitted by the asterisk 8 due to its placement on the drive

about its axis. The rotation of the sprocket 8 is provided by moving the teeth of the gear wheels 9 mounted on the drive shaft 7 relative to the teeth of the gear teeth 10 mounted on the sprocket 8 and made spherical in shape (with the radius of the dividing sphere R) with the center in the dot O, which coincides with the point relative to which the sprocket 8 rotates. At the same time, the contact area of the teeth of the sprocket 8 and the fingers 11 of the raki 12 remains constant, and the axes of the aldemony 1 1 and the asterisks 8 are paralellate. Oscillating movements of the body of the combine 4 in the plane of the newly exposed surface also do not transmit KOp; iycy 1 of the gear mechanism due to its location on the head 2 in the bore 3 of the body of the combine 4.
