Description

This invention relates to the mechanization of the excavation of minerals by cleaning complexes and aggregates intended for chainless systems for feeding excavation machines.

The purpose of the invention is to unify the application to conveyors with different length of pan and different frame sizes of driving wheels of propellers.

FIG. 1 shows a side rail, side view; FIG. 2 is a section A-A in FIG. 1 (the rail is made in the form of one row of articulated rhombic polyphons); on fig.Z - section bb in fig. 1 (the rail is made in the form of two parallel rows of hinged rhombic multievenals).

The guide rail is made in the form of sections of a hinged rhombic multi-link, including links 1 equal to

lengths pivotally interconnected both in the middle part and at the ends. The links of links 1 at the ends are made by the elements 2 and 3 of the engagement, and the end links 4 of the hinged rhombic multi-link are made in half the length of the links 1 and contain central end hinges made in the form of fingers 5, through which the rail section is attached to the brackets 6 and 7 rigidly mounted on adjacent sections 8 and 9 of the downhole conveyor.

To increase the reliability, the sections of articulated rhombic multilinks 1-2-3-4 can be installed in two parallel rows interconnected by engagement elements 2 and 3 at the ends of links 1 of equal length and with fingers 5 in the middle part of their length. Section directed About SP

The connecting rod 10 bridges the gap 10 between the sections 8 and 9 of the downhole conveyor. The adjacent sections of the guide rail (shown by dotted lines) are attached to brackets 6 and 7 with the same fingers 5.

The device works as follows.

When the gear feed gear (star) mounted on the output shaft is run-in along a guide rail, sections of which are fixed by means of pins 5 on brackets 6 and 7 rigidly fixed on sections 8 and 9 of the bottomhole conveyor, as a result of interaction of the teeth of the wheel with the engagement elements 2 The guide rail moves the shearer (not shown).

Claims (2)

1. Guide rail of a chainless feed system, including attached to downhole conveyor and its overlapping joints, sections with engagement elements, about t-l and so that in order to unify the application to conveyors with different length of pan, and different sizes of drive wheels of propulsive devices, the sections are made in the form of a hinged rhombic multi-element, while the engagement elements are made in the form of articulated joints of the multi-link, and the sections are fastened to the conveyor frame by means of end central hinges in the form of fingers. 2. Rake pop.1, from the fact that, in order to increase reliability, the articulated rhombic multi-links are installed in two parallel rows symmetrically with the longitudinal axis of the rail section and interconnected by engagement elements.
