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 continuous feed machine for trimming and separating plant material, the machine having one or more augers or conveyors for feeding plant material into a trommel barrel covered with mesh netting, adapted to include baffles between longitudinal sections of the trommel barrel, and sized for rotational speeds to so as to process the plant material as components of the plant material progress longitudinally through successive sections of the trommel barrel. The mesh netting trims plant material as it moves through the trommel barrel, with the trim falling through the mesh netting. One or more augers or conveyors may be used to remove trimmed plant material exiting an output end of the trommel barrel, and one or more augers or conveyors may be used to remove trim material from below one or more sections of the trommel barrel.

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.

Embodiments of the present invention pertain to a plant trimming device having a removable cutting cartridge. A direct-drive motor is magnetically coupled to the cutting cartridge. The cutting cartridge houses a blade and a set of rotating blades. Plant parts are cut by the rotating blades across the razor. The cartridge is mounted on rails and has a handle to facilitate the ease of inserting and removing the cutting cartridge. Thereby, an old cutting cartridge is readily removed and replaced by a new cutting cartridge. Furthermore, the cutting cartridge can easily be removed for cleaning and later re-inserted back into the plant trimming device.

Embodiments of the present invention pertain to a modular plant trimming system. A number of plant trimming machines are placed side by side. These plant trimming machines trim leaves from a plant. A sensor detects when one or more of the plant trimming machines are added or removed from the system. A processor then balances a load of plants to be trimmed to be split between the currently available number of plant trimming machines.

Embodiments of the present invention pertain to a tiltable tumbler for use in a plant trimming machine. Plants are placed in a tumbler. As the tumbler rotates, leaves extending through slots in the tumbler by a vacuum are trimmed off. A mechanism is used to adjust the tilt of the tumbler. Thereby, the rate by which the plant material in the tumbler is processed is faster with a higher tilt or slower with a lower tilt. The degree of tilt is adjustable either manually or automatically via a computer.

An apparatus has a trailer with one or more wheels and a connector that connects the trailer to an automotive machine that mobilizes the trailer from a first position to a second position within a field of one or more plants. Further, the apparatus has a branch trimming device operably positioned on the trailer. Additionally, the apparatus has a conveyer belt operably positioned on the trailer. The conveyer belt receives a trimmed plant that has one or more branches trimmed off by the branch trimming device. The apparatus also has one more cutting devices. Finally, the apparatus has a tumbler that receives the trimmed plant from the conveyer belt and rotates with respect to the one or more cutting devices to cut the trimmed plant into the one or more buds. A bottom portion of the tumbler is positioned in proximity to the one or more cutting devices.

A rotary drum trimmer device with one or more dynamic shear bands. The trimming device receives plant material through a hollow interior of a generally cylindrical drum having a plurality of perforations extending through its sidewall. The perforated drum rotates to tumble plant material within its interior thereby exposing portions of the plant material through perforations in the drum sidewall. Disposed against an outside surface of the rotating perforated drum are one or more shear bands. Rotary moment of the drum relative to the shear bans(s) severs plant material extending through both elements. The shear band is configured to move (e.g., reciprocally) relative to the perforated drum while the drum rotates to improve trimming.

A foliage shredder that can shred inputted foliage matter into uniform sized particles without pulverizing the inputted foliage matter includes a housing, a shredding axle, a motor, a stand, a digital timer, a power cord, and a lid. The shredding axle is concentrically positioned within a cylindrical compartment of the housing and rotatably coupled to a rotor of the motor. A stator of the motor is externally connected to the housing and electrically connected to the power cord through the digital timer. The lid is terminally attached to the housing thus closing the cylindrical compartment. The cylindrical compartment functions as a container unit for the inputted foliage as the electrically powered shredding axle shreds the inputted foliage into uniform sized particles.
