EXTRUDER FOR PRODUCTION OF PEAT POTS Russian patent published in 2015 - IPC B29C47/38 B30B11/24 

FIELD: process engineering.

SUBSTANCE: invention relates to extruders and can be used for production of fuel briquettes and planting peat pots. Claimed extruder comprises the frame with brackets for installing at the power means, drive mechanism with reduction gearbox and safety coupling and bin for process material to be loaded therein and variable-pitch auger, said extruder with said bin being mounted at said frame. End screw is mounted on output shaft of the latter and provided with rod fitted in conical adapter. Shutter is articulated with adapter end for intermittent closure by its plane the conical adapter outlet. End screw end does not extend to shutter plane at conical adapter outlet closed state by magnitude A equal to peat pot bottom depth. Note here that said shutter has the drive while its outline over perimeter is sharpened. Note also that said shutter can be detached while shims are fitted between said shutter and mating face.

EFFECT: longer life, adjustable clearance between shutter plane and adapter outlet end face.
