Изобретение относитс к области механизации подземной выемки угл , в частности к бесцепным системам подачи выемочного комбайна.The invention relates to the field of mechanization of underground coal mining, in particular, to chainless feeding systems of a mining combine.

Известен механизм подачи горных комбайнов, включающий редуктор, на выходном валу которого установлено цевочное колесо с зубь ми, вход щими в зацепление с зубь ми звезды, установленной на оси кронштейна, направл ющую рейку, в которой размеще ны пальцы 13A feeding mechanism for mining combines is known, which includes a gearbox, on the output shaft of which a pinwheel with teeth is mounted that engages with the teeth of a star mounted on the axis of the bracket and guides the rail in which the fingers 13 are placed.

Недостаток данного устройства его конструктивна сложность.The disadvantage of this device is its structural complexity.

Известен механизм подачи выемочного комбайна,.включающий цевочную направл ющую, соединенную опорами с направл ющей конвейера и ведущую звезду с приводом 123Недостатком данного механизма вл етс то, что направл юща через JL-образные опоры располагаетс в специальном желобе с завальной стороны конвейера. На жесткую направл ющую устанавливаютс захваты, удерживающие комбайн на забойном конвейере.The excavator feed mechanism is known, which includes a lantern guide connected by supports to the conveyor guide and a driving star 123. The disadvantage of this mechanism is that the guide through JL-shaped supports is located in a special groove on the intake side of the conveyor. The grippers holding the harvester on the downhole conveyor are mounted on the rigid rail.

Такое конструктивное выполнение имеет невысокую надежность и прочность конструкции, так как усили подачи и усили от поперечного смещени комбайна передаютс на борт кабелеукладчика и.его крепление .к кронштейнам крепи, которые не могут восприн ть эти нагрузки; сложность Such a constructional implementation has a low reliability and structural strength, since the feed and force forces from the transverse displacement of the combine are transmitted aboard the cable layer and its fixture to the support brackets that cannot absorb these loads; complexity

to конструкции, так как требуетс наварка полос на всей длине става конвейера дл организации желоба. Это определ ет необходимость специального исполнени конвейера и создает сложts ности в эксплуатации. Во врем работы происходит заклинивание 1 -образных опор направл ющей в желобе и резкие срывы в местах заклинивани , что создает вредные динамические нагрузки to the construction, since welding of the strips along the entire length of the conveyor bed is required for the organization of the chute. This necessitates a special design of the conveyor and creates difficulties in operation. During operation, jamming of 1-shaped supports of the guide in the gutter occurs and abrupt breakdowns in the places of jamming, which creates harmful dynamic loads.

Claims

The purpose of the invention is to increase the reliability and simplify the design of the feed system. 3 This goal is achieved by the fact that in the feeder, which includes a lantern guide, connected to the conveyor belt by bearings, a driving star with a drive, each support is made as mounted on the conveyor guide of the split sleeve and connected to it in the upper part of the bracket associated with the pinwheel direction. Kah FIG. 1 shows a circuit diagram of a chainless feeding system for a notched combine; FIG. 2 — the links connecting the links of the guide with the support and fastening on the guide conveyor; FIG. 3 is a section A-A in FIG. 2. The feed mechanism includes a star drive 2, a clamping guide 3 consisting of links hinged between each other 4. The guide pin 3 is fixed at the ends to the drive heads 5 of the bottomhole conveyor 6. The link 4 of the coupling guide 3 is fixed on the bracket 7 supports 8 using fingers Each support 8 is made in the form of a downhole conveyor 6 mounted on a guide 10 with the possibility of longitudinal movement, a split sleeve 11 with a bracket 7 in the upper part for connection with a hook guide 3 and stops G2 and 13, from The inner surface of the split sleeve 1I repeats the shape of the guiding 10 of the downhole conveyor 6. The hub guide 3 is provided with through holes 14 in which fingers 15 are mounted. When the drive 1 of the feeding mechanism 1 is operated, the rotating star 2 engages with fingers 15, ensuring the advancement of the combine along the pinwheel 3, perceiving tractive effort. Such a constructive implementation of the support in the chainless feeding system of the excavation combine increases its reliability, since during operation there is no jamming and sharp cutting of the guide supports, which create harmful dynamic loads on the entire supply system, and also allows to simplify the design, since No welding of strips is required along the entire length of the conveyor bed to form a trough. The invention The feed mechanism of the excavation combine, including the lantern guide,. connected by bearings from a conveyor belt and a driving star with a drive, which is distinguished by the fact that, in order to increase the engagement efficiency and simplify the design, each bearing is made of a split sleeve mounted on the conveyor belt and connected to it in the upper part of the bracket connected from the spindle rail.
