SU427147A1 - MOUNTAIN COMBINE Ni'S. ^ IUi. - Google Patents

Description

one

The invention is intended for use by the mining industry.

Mountain harvesters are known, including a crawler track, a conveyor, berm milling cutters, two working bodies, the distance between parallel axes of which is less than the diameter of each working body, and an air drum pivotally connected by handles to the bodies of the drives of working bodies.

The proposed combine differs from the known ones in that the break drum shaft is kinematically connected with the drives of the working bodies by means of gears located inside the arms. This allows synchronization of the rotation of the working bodies.

FIG. 1 shows the proposed combine, side view; in fig. 2 - the same, front view; FIG. 3 is a section along A-A in FIG. one.

The combine includes two working bodies 1 of the drilling or plate-disk type, the distance between the parallel axes of the carrier which is smaller than the diameter of each working body, the baffle drum 2, the scraper conveyor 3, berm milling cutters 4 and the track line 5.

Each working body 1 includes the cutting bodies 6 and the engine 7. The latter is connected to the cutting bodies 6 by means of gears 8 housed in the housings 9.

The engine 7 and gears 8, housed in the housings 9, together constitute the drive of each working member.

The housings 9 are hinged to the housings 9, inside of which the gears 11 are placed on the shafts 12 connected to the gears 8 of the drives of the working bodies by means of the rollers 13.

The gears 11 are coupled through the couplings 14 to the fender drum 2. The arms 10 are interconnected by means of a beam 15, to which the hydraulic jack 16 is attached. The combine works as follows.

When you turn on the engine 7 working bodies 1 through the gears 8 get the rotation of the cutting bodies 6, which process the main area of the slab. The direction of rotation of the working bodies is depicted

The arrows in FIG. 2. Moreover, the distance L between the axis of rotation of the working organons is less than the diameter D of each of them.

Upper ridge C remaining from the two working bodies on the roof of the passable production is removed by the fender drum 2, which also receives rotation from the gears 8 of the drives of the working bodies through rollers 13, gears 11 placed in the handle x 10 and coupling 14.

The arms 10, on which the baffle drum 2 is placed, are fixed on the housings 9 of the actuators of the working bodies hingedly and can be rotated relative to the axes O-O by the hydraulic jack 16, with the help of which the baffle drum is adjusted in height by applying the hypsometry of the formation and when the combine is distilled from the mine . In order to ensure the rigidity of the breaker device and to ensure synchronism of the rotation of the arms, the latter are interconnected by means of the beam 15.

Ottoman drum 2 receives rotation simultaneously from two drives of working bodies, providing a rigid kinematic connection between them, excluding the meeting of cutting bodies 6 of both working bodies.

Attaching the fender to the pivot arms allows the stepless adjustment of the fender to the reservoir thickness.

Subject invention

A mining combine that includes a crawler track, a conveyor, berm cutters, two working bodies, the distance between parallel axes of which is smaller than the diameter of each working body, and a fender drum hinged to the arms of working bodies, characterized in that In order to synchronize the rotation of the working bodies, the kick drum shaft is kinematically connected with the drives of the working bodies by means of gears located inside the arms.
