The invention relates to mine the transport of continuous action, namely to the main plate conveyors.

Known plate conveyors, plate containing a tape consisting of flooring, attached to the two traction chains with the traction rollers with the possibility of movement along the guides attached to the frame (Sagmeister L.G., Sarman LN. Main underground conveyors. M.: Nedra, pp.93-96, Resv, 1968).

However, a disadvantage of the known conveyors is limited in length.

Known intermediate drive plate conveyor, containing mounted on the frame indefinitely closed on the drive and tension sprocket traction body, including plate chain attached to them fists interoperable with fists traction chain conveyor (ibid, s-100, 39 and 40).

The disadvantages of the known intermediate drive plate conveyor are the design complexity, the possibility of the dynamic loads in the interaction fists intermediate drives the traction chain conveyor, the difficulty of ensuring synchronization of the intermediate actuators for sequential installation on the conveyor intermediate drives, which reduces the reliability of the plate conveyor with increased length.

The technical result of the invention is to improve the reliability of the plate conveyor extended length, equipped with intermediate drives.

The technical result is achieved due to the fact that in a plate conveyor, a plate containing a tape consisting of flooring, attached to the two traction chains with the traction rollers with the possibility of movement along the guide rails fixed on the racks, smart actuators, each of which consists of infinitely closed on the drive and tension sprocket traction unit including a plate circuit, interoperable traction unit with plate tape according to the invention placed against each other across the width of the traction unit parts of the plate circuits connected between a U-shaped beams attached to their upper bars and wear strips of elastic material with the possibility of their interaction with the external surface of the deck plate of the tape, and the plate circuit of the upper branches of the traction unit in the spans between the drive and idler sprockets placed with the possibility of their interaction with the supports, with the bearing housing of the drive and idler sprockets and said support intermediate actuator mounted on the frame with the possibility of its displacement in the vertical square is Scoti relative to the rack conveyor and fixing them by means of screw mechanisms. U-shaped beam with a lining of elastic material can be placed on each pair of link plate chains or at a distance from each other by a multiple step arrangement of the links of the traction chain length of the intermediate circuit of the drive. As supports for the plate circuits of the intermediate actuator can be made sliding bearing or rollers.

Plate conveyor is presented in figure 1 is a side view of the carrying branch plate tape and with the supports slide to the plate circuits of the intermediate drive and overlays with their solid placement figure 2 - the same, with the supports in the form of rollers and pads when they are intermittent placement relative to each other, figure 3 - section a-a of figure 1.

Plate conveyor plate contains a tape consisting of deck 1, attached to the two traction circuits 2 and 3 with the driving rollers 4 and 5 with the possibility of movement along the guides 6 and 7, secured to the uprights 8 and 9. On installed on the racks 8 and 9 frames 10 under load-carrying branch plate tape placed intermediate drives.

The shaft drive sprocket 11 is kinematically connected to the engine of the intermediate actuator (not shown).

Plate conveyor operates in the following manner. Traction plate tape is passed along with the head actuator (not shown) intermediate drives. From each intermediate drive traction plate tape is transmitted through friction between the pads 16 of elastic mA is Arial and flooring 1. The necessary contact force plates 16 of elastic material to the Board 1 is provided by appropriate placement of the frame 10 with the intermediate actuator in a vertical plane relative to the uprights 8 and 9 of the conveyor by means of screw mechanisms 21, which provides the necessary lifting plate circuits 13 and 14 attached to them by the plates 16 and provided with the necessary force from the bottom to the deck 1.
