SU284933A1 - EXECUTIVE ORGAN OF COAL COMBINE - Google Patents

Description

Known the Executive body of the coal Combine auth. St. No. 211478, made in the form of a crown, equipped with nozzles, to which the liquid is supplied through channels in the crown body, and a cleaving head, made in the form of plowshares.

The proposed organ is characterized by the fact that valves are interconnected by means of pushers with a profile cam for controlling them in the body of the crown.

This implementation of the executive body provides water to the nozzles when they are in contact with the destroyed array.

FIG. 1 depicts the proposed executive body; in fig. 2 is a slaughter pattern.

The actuator consists of a crown / with nozzles 2 and teeth 3, mounted on the hollow shaft 4, in which valves 5, pushers 6, water supply channels 7 and 8 and the stationary part of the hydraulic coupling with seals 10, as well as a bracket 11 fixing in a certain position, by means of the coupling 9 and 12, the shaft 13, on which the cam 14 is installed, controls the operation of the valves 5, and the stationary shear head 15 with the teeth 16.

by the sleeves to the stationary part of the hydraulic coupling 9 and enters the channels 8, closed by valves 5. Then the nozzles approach the cutting zone 17 (see Fig. 2), the pushers 6, rotating with the crown / and shaft 4, run over the protrusion the fixed cam 14 and, overcoming the pressure of the water, open the valves 5.

When the nozzles exit the cutting zone 17 and move in the non-operating zone 18, the pusher comes off the lip of the cam 14 and the valve 5 closes. As a result, the water supply to the nozzles 2 is stopped until they approach the zone

cutting. The opening and closing times of the valves and the sequence of their operation is chosen so as to minimize flow pulsations and water pressure.

For one turn of the crown valve

opens once for the duration of the nozzles in the cutting zone and closes once on leaving it.

Passing through the nozzles, the water is formed into thin jets of great speed, which cut through the gap in the mountain range. To maintain the minimum distance from the nozzles to the destroyed array, teeth 3 are provided. When the actuator moves along the chest, the bottom is in the resulting gap

enter the teeth 16 of the stationary cleaving head 15. The shear head 15 breaks off the formed core and with the help of the crown blades / loads it onto the conveyor.

Fixing the scaling head 15 and the control valve cam 14, mounted on the shaft 13, is carried out using the coupling 12, the fixed part of the hydraulic clutch 9 and the arm 11.

Subject invention

P1polnktelny body of a coal combine at aut. Sat No. 211478, characterized in that, in order to ensure the supply of water to the nozzles when they are in contact with the breakable array, valves are interconnected by means of pushers with a profile cam for controlling them.
