A leaf removal assembly including a frame comprising a front plate having a feed opening, a leaf stripping assembly mounted on said front plate in front of said feed opening and an upper sprocket wheel comprising a plurality of upper socket grippers extending radially outward of the upper sprocket wheel and being disposed behind the front plate. The leaf removal assembly further includes a lower sprocket wheel comprising a plurality of lower sprocket grippers extending radially outwardly of the lower sprocket wheel and being disposed behind the front plate. At least one of the upper sprocket wheel and the lower sprocket wheel may be adjustably attached to the frame. A process for separating a leaf from a stalk comprising at least one leaf is also included.

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 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.

A method for threshing and pneumatic separation of tobacco leaves, including: 1) transporting a mixture of the tobacco slices and stems from a primary threshing set into primary pneumatic separation unit for sorting out tobacco slices, and transporting a remaining mixture into a secondary threshing set; 2) transporting the mixture from the secondary threshing set into a secondary pneumatic separation unit for sorting out the tobacco slices and qualified stems, and transferring a remaining mixture to a tertiary threshing set; 3) transporting the mixture from the tertiary threshing set into a tertiary pneumatic separation unit for sorting out the tobacco slices and the qualified stems, and transferring a remaining mixture into a quaternary threshing set; 4) transporting the mixture from the quaternary threshing set into a quaternary pneumatic separation unit for sorting out the tobacco slices and the qualified stems, and returning a remaining mixture to the quaternary threshing set.

The invention relates to a method for stripping leaves and/or flowers from a stalk (1), in particular for stripping cannabis leaves and/or cannabis flowers from a stalk (1). Thereby, a loop (2) is formed around the stalk (1) to be stripped, which is formed at least in a partial area from flexurally elastic or flexurally slack loop means (3, 3a, 3b) which have tensile strength in the direction of the loop. The stalk (1) is then pulled through the loop (2) in the longitudinal direction of the stalk, with the leaves and/or flowers being stripped from the stalk (1). The invention makes it possible to strip the leaves or flowers, respectively, more easily and directly from the surface of the stalk (1), such that they can be substantially harvested better, faster and with less damage. Less preparatory work is also required.
