Definitions

  • the embodiments disclosed herein relate to plant trimming and in particular an apparatus for trimming plants such as cannabis.
  • Cannabis is typically harvested, dried and cured to obtain the benefit of the plant’s various medicinal properties.
  • the cannabis buds and flowers contain the highest volume of both psychoactive and non-intoxicating compounds.
  • the leaves of the cannabis plant contain only trace amounts of these compounds and are typically composted.
  • Another practice is for cannabis to be trimmed using automated equipment after the plant has been harvested, dried, and cured.
  • This automated equipment is typically made up of two overlapping blades, a motor, and a sweeper all housed in a container.
  • the dried cannabis can be placed onto the overlapping blades.
  • the sweeper will rotate, driven by the attached motor. Both blades are perforated such that cannabis may enter the holes, and the portion extruding through the perforations are cut by the overlapping blades.
  • the sweeper stirs the harvested plants to increase the surface area in contact with the blades to be trimmed.
  • a plant trimming apparatus for trimming plant material comprises a housing comprising an interior and a cylindrical wall and a plurality of openings through the cylindrical wall.
  • a cutting wire in the interior of the housing passes by the openings, wherein the plant material passing through the plurality of openings is trimmed by the cutting wire.
  • the apparatus further comprises a spindle rotationally attached to the housing, the cutting wire attached to the spindle via a member, such that the cutting wire traces a cylinder when the spindle rotates, and an outlet in the housing for removing trimmed plant material.
  • FIG. 1 is a perspective view of a trimmer.
  • FIG 2 is a side cross-sectional view of a trimmer along section A-A of FIG. 1.
  • FIG 1 there is shown a perspective view of a trimmer 1.
  • the trimmer 1 described herein is a single unit used for trimming plants.
  • the trimmer 1 is provided with a housing 2.
  • the housing 2 may be substantially cylindrical with a cylindrical interior.
  • the housing 2 includes a plurality openings 3, preferably elongated, obround openings 3.
  • the openings 3 allow entry of plant material into the interior of the housing 2 but due to their size restrict the entry of larger plant material. Plant material that enters the housing intersects with the moving cutting wire 40 and is severed as described below.
  • the elongated openings 3 are small enough to block the inadvertent entry of any fingers or tools of the operator.
  • the elongated slots are preferably oriented parallel to the cutting wire described below.
  • the plurality of openings may be of different sizes.
  • a first group of the plurality of openings may have a first size and the remaining openings may have a second size smaller than the first size. In this way, rough trimming may be done using the first group of openings and fine trimming done using the remaining openings.
  • the openings 3 may extend substantially from across the housing 2.
  • the openings 3 may be integrated directly into the housing 2.
  • the openings may be formed in a grill 50.
  • the grill 50 may be affixed to the housing 2 covering a larger opening in the housing 2. In this way, the housing 2 may be easier to manufacture.
  • the grill 50 may in addition be replaceable separately from the housing 2, either when worn or damaged or with a grill 50 having different size or orientation of openings 3.
  • the grill 50 may be affixed to the housing 2 such that the interior surface of the grill is proximate to the cutting wire 40, described below.
  • the grill 50 may be removable to facilitate cleaning of the grill and/or the interior of the housing.
  • the housing 2 has a separate outlet 4 from which trimmings may be extracted from the interior of the housing 2.
  • a suction or vacuum system may be used to extract plant trimmings from the housing, through outlet 4 to a separator.
  • the separator allows for the collection of plan trimmings for packaging, drying or other aspects of the harvesting process.
  • the operation of the vacuum may be activated separately or in conjunction with the drive motor.
  • a trimmer 1 is provided with a drive motor 5, which drives a spindle 6.
  • An electrical switch 7 may be used to turn the motor 5 off and on.
  • a knob 8 may be used to select the speed of the motor 5, by for example, controlling the supply of electricity to the motor or by operating motor control circuitry that controls the motor, alternatively, the motor may operate at a single speed.
  • the spindle 6 may be connected to a first spindle plate 30 and second spindle plate 35 which occupy the interior of the housing 2.
  • a cutting wire 40 is tensioned between the first spindle plate 30 and the second spindle plate 35.
  • the cutting wire 40 is tensioned between points near the circumference of the first spindle plate 30 and second spindle plate 35, such that when the spindle 6 is rotated by motor 5, the cutting wire 40 traces a cylinder.
  • Plates 30 and 35 may be discs, rods, or other members to support the cutting wire, provide tension in the cutting wire and position the cutting wire proximate to the housing, parallel to the spindle.
  • the cutting wire may be made of plastic, metal or other material of sufficient strength to sever the plant material.
  • the cutting wire may be a blade, rod or other shape.
  • a counterweight may be provided to balance the spindle, plates, and wire so that the spinning members can rotate without undue vibration.
  • the cylinder traced by the cutting wire 40 may substantially conform to the cylindrical interior of the housing.
  • the cutting wire 40 passes close to the interior of the housing 2 proximate to the openings 3. In this way, plant material that passes through the openings 3 is immediately severed by the cutting wire 40, The plant material is held in place by the openings 3 while impacted and severed by the cutting wire 40.
  • the cutting wire 40 intersects the plant material, cutting the plant material.
  • the plant material is preferably severed by the cutting wire 40, such that cut material is passes into the hollow interior of the housing.
  • a fan or vacuum may draw the cut material through outlet 4.
  • the outlet 4 may be oriented such that cut material falls, by gravity, out the outlet 4.
  • a first end of the spindle 6 may be supported in a bearing 1 1 .
  • the bearing 1 1 may be contained in the housing and further connected to a bearing flange 12 and an end plate 13.
  • the end plate 13 may have a foot 14 extending outward from the housing 2.
  • the foot 14 may be connected to vibrational mounts 15, 16, which limit any movement of the trimmer 1 that may occur as a result of the vibrations from motor 5.
  • a second end of the spindle 6 may be connected to the drive shaft 17 of the motor 5 either directly or through a drive train or other means of transferring the rotation motion from the motor to the spindle 6.
  • the end plate 20 may have a foot 21 extending outward from the housing 2.
  • the foot 21 may be connected to vibrational mounts 22, 23, which limit any movement of the trimmer 1 that may occur as a result of the vibration generated by motor 5.
  • End plates 13 and 20 may be removable to provide access to the interior of the housing 2 for servicing and cleaning. Plates 13, 20 may be attached the housing with bolts, pins, threaded attachments, hinges, fasteners or other similar means. In some embodiments, the housing 2 may be opened by way of hinged components or other releases to provide access to the interior of the housing 2.
  • end plates 13 and 20 may be attached to the housing using fasteners 42, 44, and 46.
  • End plate 20 may have fastener openings 31 , 32, 34 and end plate 13 may have fastener openings 36, 38, 40.
  • Each opening may include a“T” shaped opening with a wide portion sized to allow tabs of fasteners 42, 44, 46 to pass through and a narrower portion that secures the tabs.
  • the openings may include a tab, over which the fastener is secured.
  • Fasteners 42, 44, 46 may be clamps with an open position and a closed position. In an open position the clamps 42, 44, 46 may pass through the wider portion of openings and engaged with the narrow portion of openings. When in the closed position, the clamps can tension the end plates 13, 20 together.
  • the openings 42, 44, 46 are shaped such that the clamping bands 42, 44, 46 can easily be manually inserted and removed when the clamps are in the open position. This configuration allows the end plates to be removed so that the interior of the housing 2 can be accessed.
  • Resin or other material from the plants as they are trimmed may build up on the trimming apparatuses, including cutting wire, spindle, spindle plates and end plates. This build up may reduce the efficiency of the trimming apparatus. The buildup may need to be removed for cleaning.
