摘要： Systems and methods for mechanical Cannabis harvesting which utilize a harvester having two counter-rotating rollers, each having a brush thereon, where the brushes serve to strip leaves and buds from the stalk of a standing Cannabis plant introduced to a harvesting space between them. The brushes transport the stripped leaves and buds to a series of conveyors that eventually deposit the leaves and buds in a hopper. The stripped stalk of the Cannabis plant may be left standing in the field to be cut down later, or may be knocked or cut down by the harvester.

摘要： A draper belt (8) having a carry layer (14), a pulley cover layer (13), and a reinforcing layer (12) which is situated between the carry layer (14) and the pulley cover layer (13). The carry layer (14) includes a plurality of cleats (7) which are reinforced with reinforcing rods (15). The draper belt (8) has a first edge section (16), a second edge section (17), and a center section (18) located between the first edge section (16) and the second edge section (17). The first edge section (16) and the second edge section (17) of the draper belt (8) each have a modulus that is at least three times greater than the modulus of the center section (18).

摘要： An agricultural harvester may include a system for determining the residue yield of plant materials being ingested by a harvesting implement of the harvester. A controller of the system may be configured to determine the weight of the quantity of plant materials being ingested by a harvesting implement of the harvester based on measurement signals received from the plant yield sensor. The system may be configured to determine the weight of the quantity of crop materials removed from the quantity of harvested plant materials based on measurement signals received from the crop yield sensor. The system may be configured to determine the residue yield value by comparing the determined weight of the quantity of plant materials and the determined weight of the quantity of crop materials.

摘要： A crop ramp and belt support component for an agricultural harvesting head is provided. The crop ramp and belt support component includes a forward portion, a rear portion, and a belt support portion that are generally planar. The forward portion is inclined relative to the rear portion, and the rear portion extends from the forward portion. The belt support portion is substantially parallel to the rear portion and is configured to extend at least partially below an interior surface of a belt conveyor. The forward portion, the rear portion, and the belt support portion are fabricated as a unitary component.

摘要： A cutter blade of a lawn mower includes a blade body and flaps. The blade body includes a shape with a sweepback angle inclined in a reverse-rotation direction of the cutter blade. The flap pivotal axis is provided along a blade edge without intersecting with a blade rotational axis. A flap pivotal axis is provided at a position offset from a line perpendicular to the blade rotational axis and in parallel to the pivotal axis, in a rotation direction of the cutter blade.

摘要： A harvesting machine has a crop tank and a conveyor screw inside the tank which extends from a material inlet opening on a wall of the crop tank into the interior of the crop tank. The conveyor screw comprises at least one proximal portion adjacent to the material inlet opening and one distal portion spaced apart from the material inlet opening at least by the proximal portion. The proximal portion and distal portion are rotatable around conveying axes running in different directions. The conveyor screw can be operated in a work position in which the conveying axis of the distal portion is oriented to be steeper than the conveying axis of the proximal portion.

摘要： Embodiments for implementing a harvester method, system, and apparatus are provided. For example, a harvester for produce may include a fluid knife system at a front end of the harvester in a travel direction of the harvester, wherein the fluid knife system projects a fluid at a pressure and a direction that cuts produce, a roller bar including one or more fingers extending radially outward and configured to receive produce from the fluid knife system, wherein the roller bar rotates on its axis turning the one or more fingers at the front end lifting the produce cut by the fluid knife system, a plurality of conveyers that receive the produce from the roller bar and are configured to transport the produce through the harvester, and a bin system configured to receive the produce from the plurality of conveyers and package the produce into one or more bins.

摘要： A header includes a forwardly disposed cutter bar assembly and a rearwardly disposed draper deck assembly. The draper seal includes a flexible strip that runs parallel to the cutter bar assembly and perpendicular to the direction of travel. A bracket secures the forward edge of the flexible strip to an upper surface of the cutter bar assembly, which bracket also biases a rearward edge of the flexible strip into engagement with an upper surface of the draper deck assembly, thereby creating a seal between the cutter bar assembly and the draper deck assembly.

摘要： A draper platform includes a drive roller and an idler roller spaced from the drive roller. A belt is operatively coupled to each of the drive roller and the idler roller. The draper platform also includes a belt tensioning system, including a tension adjustment rod. A worm gear is operatively coupled to the tension adjustment rod. A sector gear is in meshed engagement with the worm gear. A push rod is operatively coupled to each of the sector gear and the idler roller such that rotation of the sector gear causes translation of the idler roller so as to adjust tension of the belt.
