Изобретение относитс к оборудованию дл механизации подземной выемки угл , в частности к очистным комбайнам.The invention relates to equipment for the mechanization of underground coal excavation, in particular to shearer combines.

Известны механизмы подачи очистных комбайнов, перемещающиес по ставу конвейера , включающие корпус, редуктор, приводньй элемент и зубчатую рейку, шарнирно закрепленную на секции конвейера 1.Known supply mechanisms for shearers moving along a conveyor bed, including a housing, a gearbox, a driving member, and a toothed rack hinged on the conveyor section 1.

Недостатком данных механизмов вл етс то, что приводной элемент входит в зацеплений-с рейкой консольно (с одной стороны рейки), вследствие чего возникает момент, способствующий выламыванию рейки .The disadvantage of these mechanisms is that the drive element engages with the rail from the cantilever (on one side of the rail), as a result of which there is a moment conducive to breaking the rail.

Наиболее близким техническим решением вл етс механизм подачи опытного комбайна , включающий редуктор с валом и ведущей звездочкой и рейку, шарнирно закрепленную на конвейере 2.The closest technical solution is the feeding mechanism of an experienced combine, including a gearbox with a shaft and a driving sprocket and a rail hinged on the conveyor 2.

Недостатком данного устройства вл етс то, что ведуща звездочка входит в зацепление с рейкой консольно, что приводит к выходу рейки из стро и приводит к нагрузкам на рейку.The disadvantage of this device is that the drive sprocket engages with the rail console, which leads to the release of the rail and the load on the rail.

Цель изобретени - обеспечение надежности зацеплени и снижени нагрузок.The purpose of the invention is to ensure reliable engagement and reduction of loads.

На фиг. 1 изображен комбайн с предлагаемым механизмом подачи в комплексе с конвейером; на фиг. 2 - узел I на фиг. 1, установка цевочных реек двух соседних секций) фиг. 3 - разрез А-А на фиг. I; 5 на фиг. 4-6 - возможные расположени звездочек на механизме подачи относительно цевочной рейки.FIG. 1 shows a combine with the proposed feed mechanism along with a conveyor; in fig. 2 — node I in FIG. 1, the installation of the lanterns of two adjacent sections) FIG. 3 shows section A-A in FIG. I; 5 in FIG. 4-6 are the possible locations of the sprockets on the feed mechanism relative to the spreader rail.

Механизм подачи состоит из корпуса 1, в котором размещен редуктор. Редуктор имеет два выходных вала 2 (фиг. 3), которые в корпусе соединены щестерн ми 3, имеющими одинаковое число зубьев, а на выходных концах установлены звездочки 4.The feeder consists of body 1, which houses the gearbox. The gearbox has two output shafts 2 (Fig. 3), which are connected in the housing with 3-pointed brushwheels with the same number of teeth, and sprockets 4 are installed at the output ends.

Указанна цель достигаетс тем, что 15 механизм подачи очистного комбайна, включающий редуктор с валом и ведущей звездочкой и рейку, шарнирно закрепленную на конвейере, снабжен дополнительной ведущей звездочкой с валом, установленным в редукторе, при этом ведущие звездочки ус20 тановлены с возможностью взаимодействи с рейкой с двух противоположных сторон.This goal is achieved by the fact that the feed mechanism of a shearer, including a gearbox with a shaft and a leading sprocket and a rail hinged on the conveyor, is equipped with an additional drive sprocket with the shaft installed in the gearbox, while the drive sprockets are mounted with the ability to interact with the rail two opposite sides.

Claims

Leading sprockets are offset along the longitudinal axis of the rail by a multiple of the engagement step. The arrangement of the stars relative to each other can be performed in various versions. For example, with installation against each other on the same axis with gearing with a two-row pin rail (Fig. 4) or offset relative to each other along the longitudinal axis and with gearing with a two-row (Fig. 5) or one-gear (Fig. 6) pin rail. A prerequisite is for star sparger to the spreader rail on both sides. The pin sets 5 (figs. 1 and 2) are set section by section with the help of 2 joints on the sections of the conveyor and have no connection with each other. The hinge consists of stops 6 (Figs. 2 and 3) rigidly mounted on the housing of the rail, eyelet 7 fixed to the conveyor section, and a spherical finger 8. The hole of the eyelet 7 is made in the form of a groove that allows the rail to move up to the stop into the side 9 of the section conveyor belt While moving the sprockets 4 (fig. 3) along the rail, they are installed both in the transverse and longitudinal directions, shifting against the abutment into the bead 9. At this, the coupling pin is automatically installed at the junction of the rails. The proposed feed mechanism in combination with a self-aligning pin rail has the following advantages as compared with the known mechanism: the engagement geometry is greatly improved; dynamic loads are reduced both on the rail and on the drive mechanism; there is a smoother transition of stars at the ends of the rails; The traction forces of the feed mechanism are perceived by only one rail and are transmitted through the support to the whole conveyor, the remaining rail is unloaded at this time. All this greatly increases the reliability of the system as a whole. Claims 1. A shearer feeder feed mechanism, including a gearbox with a shaft and a drive sprocket and a rail hinged to the conveyor, is characterized in that. in order to ensure the effectiveness of the engagement and reduce the loads, it is equipped with an additional drive sprocket with the shaft installed in the gearbox, while the drive sprockets are installed with the ability to interact with the rail from two opposite sides. 2. The mechanism according to claim 1, which differs in that the drive sprockets are displaced along the longitudinal axis of the rail by an amount that is a multiple of the link.
