SU407044A1 - THE EXECUTIVE BODY OF THE COAL COMBINE - Google Patents

Description

one

The invention relates to the coal industry, in particular to the executive bodies of coal combines for coal cleaning.

Known executive bodies of coal combines, made of a drum with a vertical axis Vrash, Yeni and gearbox.

The proposed actuator differs from the known ones in that the drum casing is provided with outer and inner rings connected to each other and to the casing by means of trunnions. This increases the destruction efficiency of the slaughter.

FIG. 1 shows the Executive body, a longitudinal section through the axles of the outer ring; in fig. 2 - the same, on the axles of the inner ring; on. FIG. 3 - structural-kinematic scheme of the executive body in axonometry.

The actuator includes an upper drive wheel 1 connected to the movable body of the drum 2, to which the inner ring 4 is pivotally connected by means of pins 3. The outer ring 5, fitted with cutting teeth and overlays 6, is connected to the inner ring through pivots 7 and rests on an inclined a guide 8 with linings 9. Inside the drum casing, a cup 10 is movably inserted with a cutting crown 11 fixed on it,

and inside the glass is built hydraulic jack 12.

The drum housing is connected through the bearings 13 and the insert 14 to the gearbox main body 15. The lower driving gear 15 is mounted on the bearings 17 fixed in the gearbox 15, and fixedly connected to the lower cutting disk 18.

The gears 1 and 16 are driven in rotation by one gear located in the flat part (turret) of the main gearbox. From the wheel 1, the rotation is transmitted to the drum 2, which is mounted on it

teeth processing at the site from the roof and below. In addition, rotation from the drum body through the trunnions is transmitted to the inner ring 4, and from it, also through the trunnions, is transmitted to the outer

ring 5. Ring 5 is equipped with cutting teeth and, when rotated, it processes the bottom section not covered by the lower disk 18 and the drum 2. To maintain stability and a certain direction

the outer ring 5 during rotation has a sliding contact with the inclined guide 8 through the corresponding removable pads 6 and 9. From the wheel 16, the rotation is transmitted to the lower cutting disc 18, cutting coal at the site of the subsoil bed.

The outer ring 5 rotates about an axis tilted by the node with an angle to the axis of rotation of the primary member. The oblique rotation of the outer ring, equipped with teeth, ensures the effective destruction of the remaining untreated zone of the slab (I) Kdu with a drum and a disk and bypassing the cutting teeth through the gear drive body, and also allows active coal loading from the slaughter zone of the bottom.

Subject invention

The executive body of the coal combine, made of a drum with a vertical

an axis of rotation and a gearbox, characterized in that, in order to ensure the efficiency of destruction of the bottom, the drum casing is provided with outer and inner rings interconnected with the casing by means of trunnions.
