Abstract

A screw conveyor that appropriately discharges chips inside cutting fluid includes: a main body in the form of a container provided with a storage tank; a screw rotatably assembled inside the storage tank; a discharge pipe formed at a rear side of the main body and connected to the storage tank; an inlet section configured to receive the chips and the cutting fluid into the storage tank at a front side; a guide plate configured to guide the chips and the cutting fluid to the screw; a screw cover provided with multiple fine holes configured to cover a space above the screw; and an opening formed in the storage tank at a position higher than the screw cover such that the cutting fluid enters inside the main body.

First claim

1 . A screw conveyor comprising:
a main body in the form of a container provided with a storage tank configured to collect chips and cutting fluid; a screw rotatably assembled inside the storage tank; a discharge pipe formed at a rear side of the main body and connected to the storage tank; an inlet section configured to receive the chips and the cutting fluid into the storage tank at a front side opposite to the discharge pipe; a guide plate configured to guide the chips and the cutting fluid to the screw, the guide plate being provided to the rear of the inlet section; a screw cover provided with multiple fine holes configured to cover a space above the screw, the screw cover being provided to the rear of the guide plate; and an opening formed in the storage tank at a position higher than the screw cover such that the cutting fluid enters inside the main body.

2 . The screw conveyor according to claim 1 , wherein
an end plate is provided joined to both a front end and a rear end of the screw cover so as to surround the screw together with the screw cover.
