A system for identifying weeds present within a field includes an imaging device configured to capture an image depicting a plurality of plants present within the field. Furthermore, the system includes a computing system communicatively coupled to the imaging device, with the computing system configured to receive the image captured by the imaging device. Additionally, the computing system is configured to identify a stalk of each of the plurality of the plants depicted within the received image. Moreover, the computing system is configured to determine a parameter associated with each identified stalk. In addition, the computing system is configured to identify each plant of the plurality of plants as a crop or a weed based on the corresponding determined parameter.

A method is provided for operating a system consisting of an agricultural working vehicle, at least one working tool arranged thereon, and a controller assigned to the working vehicle. The method includes detecting, by at least one sensor assembly arranged at least on the working tool and having at least two sensors, two different physical variables. The method further includes storing, by a memory, information characterizing the working tool, continuously storing, by the memory, operating data of at least the working tool, and communicating wirelessly via Bluetooth network with the controller by the at least one sensor assembly via a transmitter. The controller is brought into a transmission range of the sensor assembly to activate the communication between them and the operating data temporarily stored in the memory is transmitted to the controller.

The present invention is directed to a spray boom for an agricultural machine in which the boom is arranged as a truss with interior diagonal struts of the truss being configured to absorb tension and compression energy imparted by deflections over the length of the boom with such energy being dissipated as heat. In one aspect, the diagonal strut could comprise a rod moveable with respect to a tube with a polymer, such as an elastomeric material, arranged in the tube to dampen the movement. The tension and compression of the diagonal strut could subject the dampener to a shearing force which could be absorbed by the dampener rather than transferred to the machine.

A connector body having a first end portion defining a first end face of the body and an opposite second end portion defining a second end face of the body, the first end portion including a first peripheral groove with a first sealing ring, and the second end portion including a second peripheral groove with a second sealing ring, an intermediate portion of the—body defining a peripheral surface extending between the first sealing ring and the second sealing ring, the peripheral surface to be covered by the retaining glue for bonding the body to the tube, a glue flow passage at the first end portion extending transversally to the first sealing ring, and a glue injection channel extending from the first end portion towards the second end portion and including a glue injection port in the first end portion and a glue ejection port at the peripheral surface.

A boom height control system for an agricultural crop sprayer includes a spray boom and an actuator arranged to adjust a position of at least a portion of the spray boom in response to a position adjustment command. A speed sensor is provided to measure a forward speed of the sprayer and generate a speed value. A position sensor is provided to measure a current position of the spray boom portion and generate a current position value. A controller is in communication with the speed sensor, the position sensor and the actuator. The controller is configured to generate the position adjustment command based upon a target position value, a current position value and a speed value.

A fluid dispersion system and method used for spraying large areas with near-monodispersed, aerosolized fluid droplets. More specifically, the system creates and distributes a cloud of near-monodispersed droplets of fluid by pumping pressurized air and fluid through fluid dispersion machinery and into, and out of, a fluid dispersion nozzle. The fluid dispersion machinery is a combustion engine-driven air compressor system that includes an engine, radiator, fuel tank, fluid tank, fluid piping system, fluid pump, air compressor, air compression intake, one or more fluid dispersal nozzles, air ducting, clutch, and control system. The method of fluid dispersion is implemented at night during a nighttime air inversion when there is a temperature difference between the temperature of air at the top of an object and the temperature of air near the ground surface.

A precision agriculture support system is provided with a measuring device, a storage device and a plant species determining unit. The measuring device measures a first spectral characteristic of light derived from vegetation in a support target area. The storage device stores a database of spectrum according to species that shows a spectral characteristic of a desired crop. The plant species determining unit determines whether a plant included in the vegetation is the desired crop or not based on the database of spectrum according to species and a measurement result of the first spectral characteristic. The plant species determination unit further carries out distinction of agricultural crops, distinction of agricultural crops and weeds and the like. Furthermore, the precision agriculture support system identifies an area where abnormality is occurring, estimates a nature of the abnormality and carries out an early warning by providing a countermeasure against the abnormality.

A spraying work method includes generating a target route for a work vehicle that performs a spraying work on crops arranged in a plurality of rows in a field, causing the work vehicle to autonomously travel along the target route, and switching a spraying direction of a spray material for the crop by spraying units and provided in the work vehicle in accordance with a position of either the crop on a work route, on which the work vehicle performs the spraying work while autonomously traveling, or the crop adjacent to the work route.

An automatic traveling method includes causing a work vehicle to automatically travel according to a target route in a farm field, execute a spraying work of spraying a chemical liquid on crops, execute a stirring work of stirring the chemical liquid in a storage tank, and start the stirring work if a predetermined condition is satisfied before the work vehicle starts automatic travel.

A spraying machine includes a machine body, a support frame, and a spraying portion. The support frame includes a horizontal frame having a length along a left-right direction, and a pair of vertical frames and each having a length along an up-down direction, and protruding downward from both ends of the horizontal frame. The spraying portion is supported by the support frame, and sprays a spraying material. The support frame is supported by the machine body to be rotatable around a rotation axis passing through a fulcrum portion provided on the horizontal frame and extending along a front-back direction, while maintaining a relative positional relationship between the pair of vertical frames and the horizontal frame.
