1, cam device It is plunger plunger, the next move mechanical energy input device; 2, the hydraulic control device according to the system hydraulic pressure rise or fall, through the role of its internal small piston driven by the forklift plunger plunger pump anti-clockwise or clockwise rotation of an angle; 3, the working cylinder to provide gold ore crusher thrust plate thrust required for normal work, overloading cylinder pressure rise, the piston moved back to the right to limit the maximum crusher crusher force; 4, the action valve action valve designed for their own devices, there are two different area of ??the piston, when the pressure on the cavity is higher than the cavity pressure, the piston down, on the cavity drain; when the cavity pressure is lower than or equal to When the pressure in the lower chamber, the piston is in the upper limit position, the drain is plugged hydraulic system in normal working condition; 5, the accumulator to reduce hydraulic system hydraulic pulsation, so that the jaw crusher action valve in the event of overload movement accurately drain; 6, the plunger pump to provide high pressure oil system, the cylindrical surface of the plunger milling spiral chute, the tank has a channel and the plunger above the pump chamber; plunger sleeve with oil inlet and back to the oil hole. The effective stroke of the pump oil is determined by the relative positions of the plunger and the plunger sleeve. When the plunger rotates counterclockwise, the effective stroke is reduced and the pump oil is less; on the contrary, the pump oil increases.
