Technical Field

[0001] The utility model relates to the technical field of abrasives, in particular to an abrasive bin which is convenient for pouring out ground powder. Background Art

[0002] Abrasive bins are usually used to grind abrasives into powder for subsequent use. However, due to the large internal friction and cohesion, the ground powder often gets stuck in the bin or adheres to the bin wall when pouring. Opening the abrasive bin and directly disassembling and cleaning it is more effective, but it is too time-consuming and labor-intensive, and is not used unless in special circumstances. The most common way is to manually knock on the bin wall so that the abrasive bin can pour out the powder smoothly. However, the internal situation of the abrasive bin is generally not easy to observe, and it takes extra manpower to observe whether the outlet of the abrasive bin is blocked and knock and clean it in time, which is quite costly. Therefore, it is necessary to design an abrasive bin that does not require too much manual processing and is easy to pour out the powder. Utility Model Content
