A system (10) for treating produce includes an application system (12) for applying a treatment liquid to the produce. A piston pump (20) is connected in liquid flow receiving communication with a source of treatment liquid (16), and also is connected in liquid flow expelling communication with an application line (18) leading to the application system. A control system (22) controls the operation of the piston pump to pump a selected dosage of the treatment liquid from the source of treatment liquid (16) to the application system (12).

The present invention relates to a novel apparatus for delivering herbicide and/or fertilizer to row crops that includes an array of ultrasound detector pairs that is aligned perpendicular to the row crops, and a sprayer positioned between the ultrasound detectors of each ultrasound detector pair wherein each of the ultrasound detector pairs has a tunable detection window at a desired distance from the sensor.

A fluid dispersion system for agricultural sprayers may include a first axial fan within a first housing and a second axial fan within a second housing for driving air toward a dispersion chamber. The diameter of the first axial fan and housing may be less than the diameter of the second axial fan and housing such that, during operation, air is forced through the first housing and the second housing while air is also entrained around the first housing into the second housing. The configuration of the axial fans and housings creates turbulence within the dispersion chamber to amplify the dispersion of fluid dispensed within the dispersion chamber by one or more fluid nozzles. One or more air baffles may be disposed within the dispersion chamber to amplify air turbulence within the dispersion chamber.

This automatic travel system for a work vehicle is provided with: a position information obtaining unit; and an automatic travel control unit that causes a work vehicle to automatically travel along a target path. The automatic travel control unit sets a control target position on the target path including a plurality of work paths arranged in parallel with each other and a plurality of turning paths that connect the work paths in an order of travel of the work vehicle, to enable automatic travel of the work vehicle along the target path. The automatic travel control unit, when the work vehicle is positioned on a work path in the vicinity of a boundary with a turning path, sets the control target position on an extension of the work path. The automatic travel control unit, when the work vehicle is positioned on a turning path in the vicinity of a boundary with a work path, sets the control target position on the work path.

This automated travel system for spraying work has a target path generation unit for generating a target path for a spraying work. A work vehicle is provided with left and right liquid spraying units which have spraying patterns including: a four-direction spraying pattern in which each of the left and right liquid spraying units sprays a liquid to both the left and right directions; and a direction-restricted spraying pattern in which the number of spraying directions of the left and right liquid spraying units is restricted to 3 or less. The target path generation unit generates the target path P in a path setting to incorporate a four-direction spraying path for which the four-direction spraying pattern is set as a spraying pattern and direction-restricted spraying paths for which the direction-restricted spraying pattern is set as a spraying pattern.

Implements and applicators provide for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a base disposed between adjacent rows of plants, and at least one application member connected to the base and disposed to apply fluid to a rhizosphere of a row of the plants.

The present invention relates to an autonomous agricultural vehicle (1) comprising a framework (2) and wheels (3), the framework (2) having a width, two flanks, one on each side of a longitudinal axis (X) of the autonomous agricultural vehicle (1), and a top, at least one tool being able to be housed in a working volume (20) defined by the width and the top of the framework (2), the autonomous agricultural vehicle (1) moreover comprising a hydrogen-powered propulsion system comprising at least one hydrogen fuel cell (100). The autonomous agricultural vehicle according to the invention moreover comprises at least one hydrogen cylinder (11,12) positioned longitudinally on the top of the framework (2), the hydrogen fuel cell (100) being configured to consume hydrogen from the at least one hydrogen cylinder (11, 12) and oxygen captured from the air so as to supply electrical power to an electric motor of the hydrogen-powered propulsion system.

Described herein are implements and applicators for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, a fluid applicator for applying fluids to plants in rows in a field includes a base, at least one flexible or pivoting application member connected to the base and disposed to apply fluid to the plants, and a stabilizer associated with the at least one flexible or pivoting application member. The stabilizer can reduce movement of the application member to provide a more consistent fluid application to the plants.

This automatic driving system for a work vehicle is provided with: a position information obtaining unit; and an automatic driving control unit that causes a work vehicle to automatically travel along a target path. The automatic driving control unit sets a control target position on the target path including a plurality of work paths arranged in parallel with each other and a plurality of turning paths that connect the work paths in an order of travel of the work vehicle, to enable automatic travel of the work vehicle along the target path. The automatic driving control unit, when the work vehicle is positioned on a work path in the vicinity of a boundary with a turning path, sets the control target position on an extension of the work path. The automatic driving control unit, when the work vehicle is positioned on a turning path in the vicinity of a boundary with a work path, sets the control target position on the work path.
