Title:
RAW MATERIAL THROW-IN SHUTE
Document Type and Number:
Japanese Patent JP2022072692
Kind Code:
A
Abstract:
To provide a raw material throw-in shute that is not easily damaged by raw-materials of high hardness or heaviness and can throw raw-materials into a crusher without outward scattering.SOLUTION: In a raw material throw-in shute A placed between a conveyor B and a crusher C, a tubular shute housing 5 is composed of a bottom plate 1 arranged at an angle, a cover plate 2 arranged almost vertically and two side plates 3, 3 fixed between the bottom plate 1 and the cover plate 2, and raw material temporary retention means 10 formed in a grid pattern by combining a horizontal rail 11 and a vertical rail 12 is formed on the bottom plate 1. When raw materials are thrown into the shute housing 5 from the conveyor B, a part of the raw materials falls to the raw material temporary retention means 10 on the bottom plate 1 and stays there. Since the temporarily retained raw materials themselves serve as cushioning material for the raw materials that fall later, damage to the bottom plate 1 can be prevented. Further, since the raw materials can be prevented from being scattered to the outside by the cover plate 2, it is possible to increase the falling speed of the raw materials and improve the operation efficiency.SELECTED DRAWING: Figure 1
