It will nevertheless be understood that no limitation of the scope of the novel technology is thereby intended, with such alterations and further modifications in the illustrated device and such further applications of the principles of the novel technology as illustrated therein being contemplated as would normally occur to one skilled in the art to which the novel technology relates.

[0018] As used in the specification and the claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Ranges may be expressed in ways including from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another implementation may include from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, for example by use of the antecedent “about,” it will be understood that the particular value forms another implementation. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint.

[0019] “Optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. Similarly, “typical” or “typically” means that the subsequently described event or circumstance often though may not occur, and that the description includes instances where said event or circumstance occurs and instances where it does not.

[0020] FIGS. 1-10 relate to a hemp harvesting apparatus and method for using the same. The hemp stripping machine 1 has a front side 33, a typically oppositely disposed ejection side 31, and an access side 32 typically extending therebetween, and further contains a plurality of brushes 15 attached to a roller drum 5. Referring to FIG. 1, there is shown roller drum 5 before brushes 15 are attached.

[0021] In reference to FIG. 2, there are shown multiple rough surface brushes 15 operationally connected to drum 5. An ordinary push broom typically used in a house or garage may be deconstructed so that that handle end is separated from the brush end. The brush end is typically comprised of a multitude of bristles attached to one side of an elongated broom head. The oppositely disposed surface is adapted to lockingly accept an elongated handle. Broom heads are typically made of durable materials, such as wood or plastic. In one embodiment, the handle of a push broom may be detached from the brush end 15 and said brush end 15 may be attached to the drum 5. Typically, a plurality of brushes 15 may be connected to roller drum 5, typically oriented so that drum 5 remains balanced when rotated. Attachment of the brushes 15 to roller drum 5 defines roller drum assembly 25. Brushes 15 may be all of one length or of a number of different lengths. Brushes 15 are typically about ten centimeters wide at the widest point and ten centimeters deep. The bristles on brushes 15 are typically made of stiff synthetic material, such as nylon or polyester but may likewise be made of natural materials, including animal hair or stiff grasses. Bristles may be flagged or unflagged, depending on the needs of the operator. Brushes 15 are intentionally staggered on the roller drum 5 so the pressure applied to the plant material during operation is intermittent instead of continuous. This intentional staggered placement of brushes 15 reduces physical stress experienced by an operator by reducing the grip pressure required while holding and inserting the plant, into machine 1.

[0022] Referring to FIG. 3, there is shown a side view of the frame 10 which houses the roller drum assembly 25. The roller drum 5 slides through the side opening 7 to operationally connect to a rotor/pulley. Brushes may be attached prior to mounting the roller drum 5 inside the frame 10, or afterward. Once the roller drum assembly 25 is mounted in place, a removable cover plate 6 may be placed over the side opening 7 to close it off, as seen in FIG. 7. The removable cover plate 6 makes the roller drum assembly 25 easily accessible for maintenance and repair. Frame 10 is typically made of solid, durable material, such as stainless steel, aluminum, or the like. Removable cover plate 6 may be made of the same material as the frame 10. Referring to FIG. 4, there is shown a front-view of the frame 10 with roller drum 5 positioned into the frame 10 and ready for the brushes 15 to be attached.

[0023] Referring to FIG. 5, there is shown a left side view of the pivot mounted cradle table 20, which is also created out of durable, solid material similar to frame 10. Cradle table 20 may be the same radius as the drum 5 or other appropriate sizes. The length of the cradle table 20 may be between sixty-one inches to sixty-five inches, and more likely between sixty-three and one-half inches and sixty-four inches. The width of the cradle table 20 may be between forty inches and forty-five inches, and more likely between forty-one inches and forty-one and three-fourths inches. Notably, however, these ranges are not meant to be limiting, as any size combination of the roller drum assembly 25 and cradle table 25 may be used.

[0024] Referring to FIG. 6, there is shown an above-view of a cradle table frame 21 of the cradle table 20 before durable materials are added and before the cradle table 20 is ready to be used. The cradle table frame 21 includes a plurality of spar braces 23, typically evenly spaced between two longitudinal bracing side walls 22. The spar braces 23 are encased with PVC plastic sheet material, which provides a durable yet smooth surface that is resistant to the friction from the bristles of the brushes 15. Referring to FIG. 8, there is shown a cradle table 20 that is ready to be attached to the frame 10.

[0025] FIG. 7 shows cradle table 20 attached to the access side 32 of the frame 10. The cradle table 20 has a curved portion for accepting the roller drum 22. This contoured shape also impacts the efficiency of the machine as the unique shape of the table 20 allows for an even pressure to be applied to the plant while the plant is fed through an access opening 16. This allows only a thin, single-line point of contact between the plant and the brush which facilitates a more efficient stripping process. In one embodiment, the cradle table 20 may be mounted to the frame 10 so that a portion of the table 20 remains outside of the frame 10 and is accessible by an operator. Further, the table 20 may be mounted on a pivot point 27 which provides best balance for tilting the table 20 prior to inserting plants and during the stripping process. The pivotable nature of the table 20 allows the correct amount of pressure to be applied to the plant during the stripping process. Once the table 20 is mounted about the frame 10, the table 20 may be fully supported by attaching support legs 24 to each side of the table 20. Attached to both legs 24 may be a horizontal support bar 26. The multipurpose horizontal support bar 26 provides further support for the table 20 and is also pressure-operated so that the operator may use their foot to raise, lower, or tilt the table 20. The pivotable nature of the table 20 also accommodates varying sizes of plants. For example, if the operator feeds a larger plant into the machine 1, he or she may apply pressure to the horizontal support bar 26 to widen the gap between the pivot table 20 and the roller drum assembly 25 so that the larger plant may fit into the machine 1. If desirable, the table 20 may also be raised, lowered, or tilted by the operator's hand. Placement of the horizontal support bar is subject to the operator's discretion.

[0026] Referring to FIG. 9, there is shown an ejection shute 30. Once the plant has been inserted into the machine and stripped of its valuable materials, the valuable materials exit the machine through an ejection shute 30 located on the ejection side 31 of the frame 10 and operationally centered thereto. The ejection side 31 is on the side oppositely disposed from the cradle table 20. At the ejection side 31 and underneath the ejection shute 30, the stripped materials may pile onto the ground or floor, into a collection container, or onto a conveyor belt.

[0027] Referring to FIG. 10, there is shown a motor 35 for spinning the drum 5. The motor 35 may be powered by 110-volt single phase electricity common household or line electricity. Higher voltage is not needed because of the low current requirements and small load on the motor 35, however, motor 35 may be of any size and power desired by the operator. The actuator 36 may be located on the motor 35 and may be controlled by the operator.

[0028] Generally, another important safety feature found insofar that the belt drive within the hemp stripper 1 is typically connected loosely enough to disengage from the roller assembly 25 and immediately stop if the operator's hand, glove, or other object gets pulled inside the machine 1. Further, an emergency stop button is located on the face of the frame 10 which interrupts the motor if actuated. These safety features reduce the likelihood of injuries occurring during use of this hemp stripper 1. In some embodiments, motor 35 is operationally connected to rotor 37 such that energization of the motor 35 urges the rotor 37 to spin, rotating the drum 5 connected thereto. In other embodiments, energized motor 35 turns a first rotatable pulley 39 that is connected to an endless belt 38, wherein the belt 38 is operationally connected to and rotates drum 5 through a second pulley 41 operationally connected thereto.

[0029] The present description is for illustrative purposes only and should not be construed to narrow the breadth of the present disclosure in any way. Thus, those skilled in the art will appreciate that nigh-infinite modifications might be made to the presently disclosed embodiments without departing from the full and fair scope and spirit of the present disclosure.
