The present concept is a plant trimming assembly for trimming materials from plants and includes a frame, and a cylindrical slotted drum rotationally mounted to the frame along a longitudinal axis. The slotted drum includes an exterior surface and a longitudinally oriented internal passageway for receiving plant material there through. It further includes a longitudinally oriented cutting assembly retainer which is also rotationally mounted to the frame about the longitudinal axis such that it rotates concentrically around the outside of the exterior surface and along the length of the slotted drum. A longitudinally oriented blade is mounted to a cutting assembly which in turn is mounted to the cutting assembly retainer. The cutting assembly rotates in unison with the retainer around the outside of the exterior surface of the slotted drum. The cutting assembly is configured to maintain a pre-selected stand-off gap between a cutting edge of the blade and a circumferential contour of the exterior surface of the drum such that plant material projecting through a slot and beyond the stand-off gap will be trimmed off by the rotating blade cutting edge.

A wood grinding machine may have a vibration detection system including one or more vibration sensors. The vibration detection system may include a trip point representative of a maximum allowable level of vibration. If a vibration signal from the one or more vibration sensors exceeds the trip point, a trip protocol may be executed to automatically stop the grinding process. Related methods are also disclosed.

A device and method for cleaning flowers and buds of plants of leaves and plant matter and particulate is provided. The buds are cleaned within a rotating drum having openings in a circular sidewall which rotates adjacent jets emitting gas. Freezing of the plant material and concurrent impacts from ice crystals formed by emitting gas, cleans the buds and flowers of unwanted plant material and particulate.

An electric trimmer has an electric motor and power source, a pair of blade plates, at least one of which is connected to an oscillator mechanism in the electric motor, and a pair of guard plates disposed one on each side of the at least one of the pair of blade plates, the guard plates hosting a matching radial or linear pattern of slots having a uniform spacing, a uniform slot width, the slots breaking out past at least one edge of the guard plates, the guard plates, in assembly, creating a gap space there between. One or more operators may insert branches having buds or flowers thereon through any one of the matching slots in the slot pattern, the branch oriented orthogonal to the blade set with the blade plates oscillating to harvest the buds or flowers within the gap space.

Disclosed is a pruning and sieving apparatus, which resolves time-consuming and laborious problems in the existing pruning method of flower plants. The pruning and sieving apparatus includes a hollow body, including two relatively disposed open axial ends; an interior pruning lining attached inside the hollow body, where the interior pruning lining includes a plurality of sidewall pruning holes arranged in a distributed manner; a sieving screen, where the sieving screen includes a plurality of sieving holes arranged in a distributed manner, and is disposed in the interior pruning lining to divide the internal space of the interior pruning lining into a pruning chamber and a collection chamber; and two end caps disposed on the two open axial ends.

A method and a device for propagating plants, by which the propagation rate or growth rate of the plants can be increased. This is achieved in that at least one plant is recorded at least in regions by an image recognition device and plant-specific features of the at least one plant are recognized by a control unit on the basis of the items of information obtained by the image recognition device. In dependence on the recognized features, at least one component of the plant is then automatically severed from the plant by a cutting means for propagation. A type and/or physical properties of the cutting means to increase a propagation rate of the plants are selected in accordance with the recognized plant-specific features of the plant.

A Concentric Blade Trimming System with Adjustable Blades. The System includes at least one pair of rotating drums within which are rotating cutting blade assemblies. The system allows the user to load untrimmed buds continuously, and to generate an efficient, continuous flow of trimmed buds as output. The cutting blade assemblies rotate within the rotating drums independently. The cutting blade assemblies also include apparatus that will automatically adjust the blade position relative to the interior walls of the drums so that the trimming process can continue without the need to shut down for blade adjustment. In an alternate version, the blades are flexible and their adjustment is conducted manually with only a short intermission in operation of the system.
