DETAILED DESCRIPTION OF THE FIGURES

[0019] FIGS. 1-9 illustrate an improved mechanical trimmer 2 and components thereof. FIG. 1 illustrates a barrel assembly 4 of the improved mechanical trimmer positioned horizontally on the frame 6 of the improved mechanical trimmer. The frame in the depicted embodiment is built using 1″ square steel coated tubing. There are four upright legs 12, 14, 16, 18, with two legs each forming opposing X shapes. The legs each are provided with tab feet 20 at a base end that support the frame on any level work surface. The opposing legs are attached via two axles 19, 21 in a pair of axles extending between the legs and forming a common axis at the top end of each leg. The frame is stabilized by two parallel cross members 26, 28 and a third cross member 29 extending between the intersection 31 of the X formed by the pairs of legs. The parallel cross members are connected to each other by support brackets 30, 32.

[0020] High grade steel fasteners, and flanged wingnuts are used to secure the support bracket. The frame parts are preferably connected using flanged fasteners that are 1.5″ and 2.5″ respectively. Threaded caps are incorporated to allow for the flanged fastener to secure the frame components.

[0021] The longitudinal axles are supported by the frame using an attached bushing. Each axle has two separate 7″ wheels 34, 36, 38, 40, also called rollers. The wheels are held in place by attached clamping shaft collars. The wheels can be adjusted to accommodate multiple barrel sizes. Preferably the barrel has tracks or channels 35, 37 for positioning the barrel on the rollers and retaining the barrel in place on the rollers.

[0022] Food grade barrels will be guided horizontally by the wheels. The wheels surface provides agitation to the drum. The barrels can easily be rotated by hand, or by attaching an electric motor 60 with pulley 62 to drive rotation of one of the axles as shown in FIG. 9. The motor is attached via perforations in the frame. The barrel is generally cylindrical in shape having a wall 7 and a floor 57.

Rotating Drum Sleeve:

[0023] The frame in FIG. 1 is shown supporting a food grade barrel. The adjustable wheel separation allows for the use of 30 gallon, and 55 gallon drums. The drum is rotated by hand or using an added electric motor when resting on the wheels.

[0024] Each barrel assembly utilizes a styrene plastic insert 44 or sleeve to support a plastic mesh basket 54. Excess plant material is trapped between the mesh and the interior of the barrel. The mesh is separated from the interior of the barrel by the insert that fits into the drum, as shown in FIG. 7. The insert has openings 39 to allow for material to pass from the mesh bag to the space between the bag and the wall of the barrel.

[0025] As illustrated in FIG. 6, the sleeve fits tightly to the interior of the barrel. This adds to the structural integrity of the design. As shown if FIGS. 7 and 8, the mesh basket 54 slides into the sleeve, and is held in place while the trimmer is being operated.

[0026] The drum sizes are 30 gallons, and 55 gallons. Each size allows for a different volume and can accommodate gardeners to large farms.

Mesh Basket:

[0027] The mesh basket 54 is designed to fit within the drum. (See FIGS. 5, 7, and 9. The basket slides into the barrel insert through the mouth of the barrel.

[0028] This design includes the use of a plastic mesh to separate unwanted plant material from harvested plants.

[0029] By using a design without blades, this trimmer can be opened up to more delicate fruits as well.

[0030] After the basket is inserted into the barrel and sleeve, the product can be added to the basket.

[0031] The primary use would be for buds or flowers; however, it could also accommodate berries and the like. In contrast, typical previous concepts that are not as versatile.

[0032] The mesh sizes can vary. The mesh ranges from ¼ inch to 1 inch for various plants. Custom weave sizes available to produce baskets.

Operation and Use:

[0033] When the frame is fully assembled, the barrel insert is placed securely into the barrel as shown in FIG. 6. The mesh basket can then be inserted into the barrel where it will be held in place by the insert as shown in FIG. 7. FIG. 8 illustrates the mesh basket and insert removed from the barrel in place to be slid into the void 53 of the barrel. The prepped material will have any large, or sun leaves, and stems removed. The dried and prepped material is placed into the barrel and the lid 10 is attached, such as by threaded engagement 61 as shown in the figures.

[0034] The barrel with prepped material lies horizontally on the wheels supported by the frame as shown in FIG. 1. The operator then rotates the barrel at the desired speed for 10 to 15 minutes.

[0035] The barrel is then removed from the Frame. The barrel can then be opened. The basket can then be pulled from the insert. The basket holds the harvested bud, flower, or fruit, and the trim material remains in the barrel. The trim can be repurposed or disposed of.

[0036] The machine can then be sanitized easily using a concentration of 1000 ppm chlorine and water, (¼ cup bleach for 1 gallon water) or cleaning alcohol. The sanitizing solution is then poured into the barrel, and is cycled on the frame for 2 minutes. The barrel should then be air dried prior to storage.
