Abstract

The present disclosure is directed to an apparatus and related methods (i.e. utilities) for trimming plants, in particular, buds and flowers, to remove unwanted plant material. A typical application would be to process a plant to leave only trimmed buds and flowers for use in potpourri, fragrant sashes, or as a prelude to further processing of essential oils. The utilities enable faster and safer production of plant material than prior plant processing machines. The utilities employ a coaxial drum and cutting element that counter rotate. This coaxial cutting element typically includes a plurality of cutting elements, to create a plurality of cutting interface that shear unwanted plant material form plant material within the drum and then collect this debris though, for example, a vacuum system. The use of the counter-rotating cutting interfaces allows for multiplying the cutting interfaces over prior existing machines.

Claims9

Dependent claims

A plant processing apparatus for trimming plant material, comprising:

a rotary trimming device comprising:
a central drum comprising first and second ends and an annular sidewall extending, along a longitudinal axis between the first and second ends, the annular sidewall having a plurality of slots extending between an inner surface and an outer surface;
and
a rotary shearing mechanism comprising a plurality of wires extending from proximate to the first end of the central drum to proximate to the second end of the central drum, wherein the wires are disposed in a helical path around the outer surface of the central drum, wherein at least a first wire is disposed at a first radial orientation relative to the longitudinal axis and at least a wire is disposed at a second radial orientation relative to the longitudinal axis;
a drum drive interconnected with the central drum, the drum drive configured to rotate the central drum about the longitudinal axis;
and
a shearing drive interconnected with the rotary shearing mechanism, the shearing drive configured to rotate the plurality of wires about the longitudinal axis and around the outer surface of the central drum.
