A harvester for removing cannabis flower from stalks includes a blade follower iris that adjusts the size of the flower-stripping opening to correspond to the diameter of the stalk. The size of the opening may be controlled by centrifugal and spring forces that cause the iris to open and close. In addition, an improved stalk-pulling belt drive conveyor system utilizes two relatively floating, releasably coupled belt systems to pinch and pull the stalk through the blade follower iris.

In some embodiments, a system includes a housing, a cutting assembly, a tine assembly, and an auger. The cutting assembly includes a plurality of axially-aligned cutting portions and a plurality of projections extending distally relative to the plurality of cutting portions and configured to urge a non-stalk portion of a plant vertically upward relative to a stalk portion of the plant. Adjacent projections of the plurality of projections extending distally from opposite sides of each cutting portion define a receiving space aligned with each cutting portion within which the stalk of a plant can be received to be cut by the cutting portion into a first plant portion and a second plant portion. The tine assembly can be rotated to urge the first plant portion into the interior space of the housing; and an auger can urge the first plant portion toward and through a rear opening.

An automatic harvesting and collecting device for sisal hemp leaves includes an up-and-down moving assembly, a steering device, a braking mechanism, a mechanical vision sensor device, a vehicle traveling and controlling device, a forward-and-backward moving assembly, an omnidirectional automatic positioning and rotating device, a shearing and clamping device, a collecting device and a frame.

A system for removing biomass from a stem includes a frame, a conveyor mechanism which moves the stem in a horizontal conveying direction, a pair of rollers which exert a rubbing force between each other for removing the biomass from the stem, and a tensioning system arranged to exert a force which holds the stem to the conveyor mechanism. A first axial end of each roller is connected to an inlet end side of the conveyor mechanism, and a second axial end of each roller is connected to a transmission such that the rollers are angled downward from the first axial ends to the second axial ends. The conveyor mechanism moves the stem so as to pass between the rollers such that the rubbing force removes the biomass from the stem, and such that the rubbing force moves downward along the stem as the stem moves in the conveying direction.

This present invention is directed to a method for the production and use of the leaf and/or leaves and/or stem(s) and/or stalk(s) of plants of the cannabis species for animal, microbial, bacteria, fungi or human consumption as a food, supplement, medicine, beverage.

Agricultural machine and method for harvesting a crop with upright stalks (29) on a soil, wherein means of transport are provided to convey the stalks (29) harvested upright to a feed-through channel (6), wherein the means of transport are provided on the front (1) of the machine and comprise at least a conveyor belt (7, 14) extending partly at the front (1) of the agricultural machine and which is designed to be driven in a direction of rotation (8) thereof in order to transport cut stalks (29) substantially upright to said feed-through channel (6). A cutter (12) is provided extending in said feed-through channel (6) to cut the stalks (29) while they are being moved upright through the feed-through channel (6).

A combine header comprising a header table with a knife extending along the front lower edge thereof. Seed pans are evenly spaced and extend forward from the front lower edge of the header table and slot is formed between them. At a middle portion of each slot a stripping plate slopes upward, outward, and rearward from a middle first point on a first one of the sidewalls forming the slot to an upper stripping edge of the stripping plate. The upper stripping edge is located above a top rear edge of a second one of the sidewalls forming the slot and aligned with same such that a vertically oriented stripping gap is formed between the upper stripping edge of the stripping plate and the top rear edge of the second one of the sidewalls. A rotating reel moves material from the seed pans rearward onto the header table.

A tumble trimmer system having a tumbler barrel with a perforated axle adapted for introducing a freezing agent such as liquid carbon dioxide or other liquefied gas adapted to flash freeze the plant material when infused into the mesh tumbler barrel, the mesh tumbler barrel adapted with mesh netting or screening for trimming and/or separating plant material enclosed therein, and with an open funnel or chute positioned below the tumbler barrel adapted to catch and direct trimmed and/or separated plant material exiting the tumbler barrel into a bin or container positioned under the funnel or chute, wherein the perforated axle comprises a plurality of perforations positioned around a circumference of and along an entire length of the axle.

A system for removing parts from plants rooted in an agricultural field while leaving other parts of the plants rooted in the agricultural field may include a harvester apparatus with an intake throat formed by structures such as the combination of an infeed head and infeed conveyor, a pair of stripping assemblies including stripping belts, or stripping assemblies including stripping members such as chains.

An apparatus and method for separating plant flowers from stalks by means of a lateral rotating tube having a plurality of flexible, elongated members affixed to and extending radially outward from the tube. The apparatus may include a platform and a frame supporting the tube above the platform to accommodate plants held between the platform and the tube so that when the tube is rotating, the elongated members affixed thereto brush against the plants and cause the flowers to brush off at and separate from the stalks. The frame further supports a housing to form a contained space, with a hood to direct the flow of flowers after separation from the stalks. The back wall is positioned a distance away from the platform to allow separated flower and stalk to be eliminated from the apparatus.
