Abstract
A trimmer comprises two counter-rotating barrels side-by-side above one cutting reel. When viewed from the front, the left barrel rotates counter-clockwise while the right barrel rotates clockwise. Plant material in the barrels accumulates on the uphill side of each barrel, relative to its rotational direction, as the plant material traverses the rotating barrels. This configuration positions the uphill sides of both barrels proximate to the one reel. The barrel perforations are rifled to assist in moving the plant material through the barrels. Screw jacks are employed to tilt the trimmer; hardware facilitates use of two such trimmers in series.
Claims19
A plant trimmer comprising:
- a first barrel and a second barrel, wherein the first barrel and the second barrel each separately comprise:
- i) an inlet into which a plant material is fed, ii) a perforated barrel through which the plant material tumbles, wherein the perforated barrel comprises a set of perforations, wherein the set of perforations allow a plant projection to protrude through the perforated barrel and be trimmed off of the plant material, iii) a primary stream outlet through which the plant material exits the plant trimmer after being trimmed off of the plant material;
- a set of mounting plates holding the first and second barrels parallel to one another on barrel bearing, wherein the barrel bearings allow the first and second barrels to rotate;
- a barrel powertrain coupled to the first and second barrels, wherein the barrel powertrain only allows the first and second barrels to counter-rotate;
- a barrel motor coupled to the barrel powertrain, wherein a rotational force from the barrel-motor on the barrel powertrain causes the first and second barrels to counter-rotate;
- one cutting reel, parallel to the first and second barrels, wherein the one cutting real rotates and cuts the plant projection which protrudes through the perforated barrels.
