Description

Technical Field

[0001] This utility model belongs to the technical field of arch-breaking devices, and more specifically, it relates to a rotary arch-breaking device for silos. Background Technology

[0002] A silo arch-breaking device is a general term for mechanical equipment or systems installed at the bottom or lower side wall of a silo, bucket, or bin to prevent and eliminate the "bridging" or "arching" phenomenon of materials, thereby ensuring that the materials can flow downward smoothly, evenly, and in a controllable manner.

[0003] Based on existing technology, it has been found that when there is insufficient material in the crusher, it will operate under "no load" or "underload", which will lead to an increase in energy consumption per unit output. When there is too much material in the crusher, it will operate under "overload", which will cause material to clog the bin, resulting in uneven particle size distribution and making it impossible to obtain uniform product quality. Common traditional arch-breaking devices on the market use pistons to impact the bin wall at high frequency to generate powerful shock waves in an attempt to shake off the adhering material. The huge impact force will cause fatigue, deformation, and even cracking of the bin wall, shortening the equipment life. Vibration may make the fine powder material more compact, which will aggravate bridging and rat hole phenomena. It is ineffective for large and solid material arches and has a limited range of action. Utility Model Content
