Description

Sawdust manufacturing device {wood chipper}

The present invention blows a part of sawdust and dust generated in the process of crushing wood step by step with a blower, sorting it, dropping it, collecting and discharging it, and crushing the remaining wood step by step to produce sawdust, so a lot of load in the work process It relates to a sawdust manufacturing apparatus that can improve productivity without receiving it.

In general, the sawdust manufacturing apparatus has a number of sawdust blades arranged on the surface of the cutting drum to crush wood to about 6mm or less like sawdust, and the wood shredder is equipped with a crushing blade on the crushing disc to crush wood to a width of 6mm or more. will be shredded with

Sawdust manufacturing apparatus up to now has a problem in that it receives a lot of load from a motor, etc. in the process of working because the wood is crushed at once in the crushing unit to produce it.

In the conventionally used sawdust manufacturing apparatus, the position of the input roller of the inlet is changed up and down to input wood. When inputting wood at the same time, the input roller forces the bulky ones first and crushes them. At this time, the small wood remaining in place due to the slip phenomenon must be pushed in by inserting the same volume of wood afterwards, which is very cumbersome. There is this.

In addition, since the continuous automatic input of wood is not carried out, time wasted when supplying wood, etc., is a cause of hindering the mass production of sawdust. The remaining small volume of wood is not completely crushed, and residues such as bark that fall when the wood is input fall into the air, causing frequent breakdowns and dust of the air, resulting in environmental pollution and lowering of work efficiency.

In addition, the produced sawdust was discharged by the wind of the blower. In this discharge method, as the sawdust scatters irregularly and falls while leaving the discharge unit, there were difficulties in collecting the discharged sawdust, and the surrounding area of the sawdust maker was also quite dirty. There is a problem with termination.

In addition, when wood is put into the input unit, wood chips or foreign substances attached to the wood fall to the lower side of the input unit and are caught in chains or other mechanical devices, which is the main cause of the failure of the sawdust manufacturing apparatus.
