Harvesting devices and methods for cannabis plants that enable efficient harvesting of floral material from cannabis plants. In various embodiments, the harvesting devices better facilitate the holding of the cannabis plant during the bucking process. In various embodiments, the harvesting devices better facilitate the bucking process and specifically the removal of the floral material from the cannabis plant with minimal damage to the floral material while minimizing user fatigue.

A hemp machine for processing hemp includes a self-propelling vehicle including a vehicle chassis and a hemp picking unit mounted on the vehicle chassis for the purpose of picking the fiber plants. The hemp picking unit includes a first picking element embodied to pick the lower part of the fiber plants and a second picking element embodied to pick the upper part of the fiber plants. The second picking element has a cutting unit for cutting the fiber plants at a position between the upper and lower part of the fiber plants.

An upstanding clamping longitudinal conveyor system for whole-stem reed harvesting includes a conveyor device, a height adjustment mechanism, and a control unit. A preharvest detection unit is configured to detect height information of reeds in a preharvest region, and transmit the height information to the control unit; a position sensor is configured to detect a current height of the conveyor device, and transmit the current height to the control unit; a lifting device is connected to the conveyor device; and the control unit is configured to calculate an average height of the reeds in the preharvest region and a height of a gravity center of the reeds, seek a height difference between the height of the gravity center of the reeds and the current height of the conveyor device, and adjust a position of the conveyor device to correspond to the gravity center of the reeds in the preharvest region.

Devices and methods of harvesting textile hemp are presented. The methods comprise mowing the hemp and wherein the cut stems are held between crossed conveyor belts and then rotated 90 from vertical to horizontal, taken over one or more times by other belts, to be deposited in parallel swaths on the field.

Systems and methods of harvesting a shrub from a base of the shrub proximate a ground surface utilizing a shrub harvester include dislodging the shrub from a base of the shrub proximate the ground surface via a shrub dislodging system on the shrub harvester. The methods also include receiving the shrub via a shrub release system on the shrub harvester. The methods further include grasping the shrub via the shrub release system on the shrub harvester. The methods also include releasing the shrub via the shrub release system, which can include a plurality of catch members.

Implementations described herein relate to methods, systems, apparatuses, and computer-readable media for computer-assisted and automatic harvest, sorting, pruning, and trimming of agricultural products. In one implementation, the agricultural product may be a hemp or cannabis product. In one implementation, the agricultural product is automatically pruned through use an artificial intelligence (AI)-generated cutting path. In one implementation, the agricultural product is supported by a clamping assembly. In one implementation, the agricultural product is imaged in a positive-pressure imaging assembly. In one implementation, the agricultural product is automatically trimmed in a positive pressure cutting assembly.

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.
