Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stone feeding bins, in particular to a stone feeding bin. Background Technique
[0002] Stone feeding bins play a crucial role in the construction industry. The main function of a stone feeding bin is to store a certain amount of stones and serve as a buffer. When the mixing equipment or other processing equipment in the production line requires stones, the feeding bin can quickly provide the required materials to ensure the continuity and stability of the production process. In some designs, the stone feeding bin also has preliminary separation and classification functions. For example, through a sieve or grading device in the bin, stones of different sizes can be preliminarily separated, facilitating subsequent mixing or processing.
[0003] However, since the stones often contain some recycled stones washed and recovered from recycled concrete waste, and these recycled stones are still adhered with some cementitious materials such as cement, this part of the stones is likely to form larger stones, and the large stones are prone to accumulate on the filter screen, resulting in blockage of the filter screen. When the production line is busy, the stones blocking the filter screen are not discovered and cleared in time. When too many stones accumulate above the filter screen, it is easy to crush the filter screen, thus affecting the separation and classification functions of the feeding bin, causing the staff to repair or replace the filter screen, which is likely to affect the production line progress. Therefore, this utility model is proposed to solve the above problems. Content of the Utility Model
