Abstract

A plant material trimmer (PMT) that cuts/separates plant leaf material from plant flower material. The PMT has a trimming assembly that includes a motor with a shaft. A propeller is attached to the motor shaft, above the motor. A twisted metal stand wire rope cutting element is attached to the propeller. An upward extending pin is located at each end of the propeller and the cutting element's ends interface with the pins. A trimming platform is located above the trimming assembly. The platform has multiple elliptical beveled slots extending therethrough. Above the platform is a conveyor assembly with a belt that rotates about two axles. A plurality of push panels are attached to the belt. A conveyor motor produces a forward movement of the belt and push panels which sweep across the platform. Wet or dry plant material is placed on the platform, and the push panels sweeping across the platform cause the plant material down through the slots. Upon exiting the slots the plant material is immediately cut by the rotating propeller and cutting element. The cut plant then falls into a mesh fabric bag located below.

Dependent claims

A plant material trimmer comprising:

a trimming assembly that includes:
a trimming motor with an upward extending motor shaft,
a propeller having a center bore,
a motor shaft that functions as a propeller shaft,
a propeller shaft collar that is placed around the motor shaft, and secured by collar pins,
a wire rope cutting element that longitudinally extends along the propeller, and including a first end and a second end,
a securing member that maintains the wire rope cutting element attached to the propeller,
a first upward extending propeller magnetic pin located adjacent a first end of the propeller, with the wire rope cutting element first end positioned on a surface of the first pin,
a second upward extending propeller magnetic pin located adjacent a second end of the propeller, with the wire rope cutting element second end positioned on a surface of the second pin, and
a trimming platform located above the trimming assembly and including an upper surface and a lower surface, the trimming platform having a plurality of slots extending through the trimming platform,
