Description

Technical Field

[0001] The present application relates to the technical field of coal feeder unloading, and in particular to a hydraulic gate valve for a coal feeder. Background Art

[0002] During the coal mining process, the coal is transported to the ore bin through the elevator, and then the vibrating coal feeder at the bottom of the ore bin vibrates the dry separation belt conveyor to feed the coal. The amount of coal fed is controlled by the opening of the gate of the coal feeder discharge port.

[0003] In the prior art, when the coal feeder adjusts the coal feeding amount, a manual gear gate is used for control. During operation, the gate opening cannot be adjusted to adjust the coal feeding amount, and the gate opening can only be adjusted after the machine is shut down. In addition, after long-term use, the edge of the manual gear gate is prone to rust, and it is not easy to adjust the gate opening. At this time, a hand winch is often used for auxiliary adjustment. However, this method is easy to damage accessories during operation, affecting production, and invisibly increasing maintenance costs and labor intensity of personnel operation.
