One embodiment of the present invention relates to an insertion plate disposed on an external surface of a cannabis bucking machine configured to receive cannabis plants containing stems and buds. The insertion plate includes a top surface, a first angled surface, a second angled surface, and a bottom surface. One or more additional angled surfaces may also be included. The first angled surface includes a plurality of insertion recesses and the second angled surface includes a plurality of insertion channels. The insertion recesses and channels are substantially conically shaped to function as a funnel for receiving larger cannabis bunches. The unique correspondence between the angle of the surfaces and the shape of the recesses allows feeders to efficiently insert larger cannabis bunches and continue to feed as the bunches are levered down from the insertion recesses to the insertion channels.

A hemp flower, bud, and leaf material stripping machine having a housing, a motor and gearbox that drive a pair of rollers inside the housing, an adjustable locking shaft that adjusts and maintains a space and pressure between the rollers, and a series of feed holes of different diameters on a front side of the housing. Each feed hole is constructed to strip flowers, buds, and leaves from a hemp stem as the stem is inserted into a feed hole and is pulled through the feed hole by the rollers. The flowers, buds, and leaves are severed from the stem at an exterior of the front side of the housing, without damage to the flowers, buds, and leaves. The feed hole is constructed with close tolerance so that the stem can pass through the feed hole but the flowers, buds, and leaves cannot. Hemp stems are stripped in seconds. The flowers, buds, and leaves are not crushed, cut, torn, or compressed as they are severed and fall into a container.

A method and device for harvesting plants belonging to the family of hemp plants (Cannabaceae), in particular of the genus Hemp, with which the harvesting and separation of the individual plant parts is made possible without damaging the individual plant parts. In particular, during harvesting, the hemp stems are pulled downwards by a pair of rollers and the flowers are pulled backwards through a chain gap, whereby the flowers are stripped from the stems.

A unique method of harvesting hemp plants is useful to isolate the leafy/flower-budded crop canopy from lower stalks of the plants to enable separate collection thereof, whereby CBD rich leaves/buds of the canopy can be processed more efficiently at an off-site facility. The harvesting method includes performing a first cutting operation at an elevated cutting height, during which the tops of the plants are detached from remnant lower stalks left standing in the field, and the detached plant tops are laid in a windrow or collected in an accompanying collection receptacle. A second cutting operation performed over the same field area at a lower cutting height serves to cut the lower stalks from the field and lay these cuttings into a separate windrow that is entirety isolated from the cut plant tops. This enables separate storage, transport and post-harvest processing of the different materials.

A method for processing hemp to form a dry hemp product including cannabinoid oil comprises steps of: (i) cutting hemp plants growing in a field between about 85 days and about 120 days after seeding, such that the hemp plants include at least one of leaves and flower buds but are free of seed; (ii) drying the hemp plants to a prescribed moisture content of about 5% to about 15%, by leaving the hemp plants in the field to air dry; (iii) shaking the hemp plants to shear said at least one of the leaves and the flower buds from stalks of the hemp plants so as to form separated stalks and said at least one of the leaves and the flower buds which are not deformed; and (iv) screening the separated stalks and the leaves and/or the flower buds so as to be separated from one another.

Described is a processing machine for processing relatively short fibre plants such as flax and relatively long fibre plants such as hemp. The processing machine comprises a self-propelling vehicle comprising a vehicle chassis provided with a first conveyor for transporting at least parts of the fibre plants from a first end to an opposite second end, and a second conveyor for transporting at least parts of the fibre plants from the first end to the second end, first and second delivering units provided at or close to the second end for the purpose of delivering and placing on the ground surface the fibre plants coming from respectively the first and second conveyor, and wherein the vehicle chassis comprises first mounting means for mounting of, as desired, either a first exchangeable picking unit or a second exchangeable picking unit.

A plant stripper is provided. The plant stripper, in one implementation includes a motor comprising a drive shaft; a first roller coupled to the drive shaft and configured to be turned by the motor; and a second roller opposing the first roller and defining a gap between the rollers for receiving a stem of a plant. A stripping guide element defines an opening disposed opposite the gap between the first and second roller. The opening is defined by a surface surrounding the opening and configured to contact plant material while allowing the stem to pass through the opening. The surface is configured to remove plant material from the stem as the stem is pulled through the opening by the first and second rollers.

The present invention provides a system for separating crop dust from crop residue produced during a harvesting operation using a combine. The system comprises an attachment member configured to be used with the combine, a shroud fastened to the attachment member and extending downward to form a negative pressure chamber; and a container for collecting the separated crop dust exiting the outlet of the cyclone unit. The attachment member comprises a suction fan to generate a negative pressure to draw an air flow comprising at least a portion of the crop dust separated from the crop residue; and a depressurized cyclone unit in communication with the suction fan, having an inlet for receiving the air flow comprising the separated crop dust drawn by the suction fan, and an outlet having a turning interlock configured to maintain the negative pressure while discharging the separated crop dust through the outlet.

Described is a processing machine for processing fibre plants. Examples of fibre plants are hemp, flax or kenaf. The processing can comprise of picking the fibre plants and then placing the fibre plants on a ground surface in a desired manner. The processing can also comprise of picking up the fibre plants which have been placed down on the ground, flipping them over and placing them down on the ground once again. The processing machine comprises for this purpose a self-propelling vehicle comprising a vehicle chassis and a processing unit mounted on the vehicle chassis. The processing unit has a transport installation for transporting the fibre plants to the self-propelling vehicle, wherein the transport installation comprises a number of guide rollers mounted on the support frame, at least one pair of endless conveyor belts guided along the rollers and at least one drive for driving at least a part of the guide rollers. The guide rollers comprise a group of at least two pressing rollers which are configured to press against a first side of a conveyor belt at two or more positions. The transport installation further comprises a support member on which the pressing rollers are arranged rotatably and wherein the support member is mounted on the support frame rotatably relative to an imaginary rotation point.
