Embodiment Construction

[0017] like figure 1 As shown, the feeding system of the present invention includes: a winch 1, a pulley fixing device, a feeder and a flexible dust-proof joint.

[0018] The hoist is a power device used to lift loads. The hoist 1 is driven by a motor. Driven by the motor, the wire rope on the hoist is wound or loosened. The wire rope is connected to the pulley fixing device. The hoist 1 or its drive Parameters such as the output power, output torque, and wire rope length of the motor can be selected and calculated according to the actual application. The winch 1 includes a conveyor detection module and a chain control module. The conveyor detection module is used to detect whether the conveyor belt is running, which can be realized by sensors and corresponding logic circuits. The sensor can be installed near the conveyor belt, and the sensor can be a photoelectric speed sensor, or other suitable sensors can be used. The logic circuit may be implemented in any circuit known...

Abstract

The invention discloses a feeding system, which comprises a winch, a feeder, a pulley fixing device and a flexible dustproof joint, wherein the winch comprises a motor, a conveyor detection module and an interlock control module; the conveyor detection module is used for detecting whether a conveyor belt of a ship unloader operates; the interlock control module is electrically connected with the conveyor detection module and is used for transmitting an interlock signal to the motor according to the operating state of the conveyor belt; the feeder is used for unloading materials onto the conveyor of the ship unloader; the pulley fixing device is connected between the winch and the feeder and is used for fixing the feeder at a horizontal position when the belt conveyor stops working; and the flexible dustproof joint is connected to an output end of the feeder and is used for preventing the materials from splashing. Due to the adoption of the feeding system, the problems of accumulating materials during machine halt and splashing the materials during startup are solved, the environmental pollution and labor intensity of cleaning are reduced, the damage of a rubber belt at a roller ofthe belt conveyor is avoided, and the safety and stability of the system work are improved.

Description

technical field [0001] The invention relates to the field of bulk material transportation, in particular to a material feeding system for a ship unloader and a control method thereof. Background technique [0002] At present, in bulk cargo terminals, intermittent ship unloaders are mainly ship unloaders with bucket door machines and bridge grabs. The bridge grab ship unloader has obvious advantages in terms of adaptability to materials and ships, operating costs, and avoiding damage to the ship unloader caused by waves. The bridge grab ship unloader is especially used in recent years. Bucket ship unloaders are the most widely used. [0003] Bridge type grab ship unloader is widely used in electric power, port, metallurgy, building materials and other industries. The ship unloader is installed along the river or on the coastal wharf. The bulk materials (coal, ore, mineral powder, cement, coke, ash, grain, etc.) in the cabin are grabbed by the grab bucket and moved to the to...
