Description

Technical Field

[0001] The utility model relates to a rotating funnel of a ship loader for preventing material from being scattered, and belongs to the technical field of mobile ship loader equipment. Background Art

[0002] Ship loader is a kind of equipment that uses cantilever belt conveyor for loading operation. It is widely used in coal, ore and other water docks. The cantilever of the rotary arm type ship loader can rotate within 240°, so as to realize the replacement of the working ship on the spot, and the loading efficiency is high. The tail car hopper of the ship loader is generally arranged at the rotation center of the cantilever. In order to adapt to the working characteristics of the arm rotation, the discharge port of the hopper does not preset the throwing angle. Because if the throwing angle toward the berth on one side is preset, when the arm rotates to the corresponding berth, the preset throwing angle is opposite to the running direction of the arm belt conveyor at this time. After the material passes through the funnel, there will be a discharge speed opposite to the running direction of the cantilever belt conveyor. After the material falls on the conveyor belt, it is very easy to cause the belt to deviate, leak and block. Therefore, the funnel can only be arranged vertically, but the vertical arrangement of the funnel still cannot solve the lateral impact of the material on the cantilever belt conveyor, and the cantilever belt conveyor will also cause deviation, leakage and blockage. Therefore, a ship loader rotary funnel is needed to prevent material spillage and belt deviation. Utility Model Content
