Abstract

In the case of an existing sawdust and woodchip hopper, when a large amount of sawdust and woodchips are inserted at the same time, the saw dust and the woodchips stick to each other and get tangled due to their load, become a chunk in an upper part and reach a deadlock without falling, so a worker has to manually break chunks of sawdust and woodchips through continuous observation, which can lead to working fatigue accumulation on the worker, and, even if the worker manually breaks the chunks, working efficiency can decrease due to irregular insertion. Also, when the worker breaks the chunks of sawdust and woodchips with a tool, the tool can damage or dent itself and internal devices of the hopper when colliding with the inside of the hopper, and the risk of work can be high. Also, when a supply amount for sawdust and woodchips is reduced to prevent the sawdust and woodchips from being hardened, an overall working speed can slow down due to a slow supply speed, and energy efficiency can be lowered as a small amount of sawdust and woodchips are continuously supplied. In order to improve such issues, provided is a hopper with the improved efficiency of sawdust and woodchip insertion. As the hopper comprises a hopper body part and a smart device application, the hopper can prevent sawdust and woodchips from reaching a deadlock after sticking to each other and getting tangled even when a large amount of sawdust and woodchips are inserted while enabling sawdust and woodchips to be continuously inserted by a constant amount, can improve the efficiency of insertion by enabling sawdust and woodchips to be continuously inserted by a constant amount without continuous observation by a worker, and can maximize the efficiency of operation energy.
