The invention relates to a sprayer of the type comprising a turbine that generates an air current, a nozzle that channels the air current and an outlet of this current to the outside, carrying with it the product dosed by a series of nozzles arranged in the area of influence of the air current, the sprayer being special in that both the air outlet opening and the turbine can be configured and act in a coordinated manner to obtain the desired air flow for each type of crop and spray application, where the optimum air flow for each spray application and the configuration of the turbine and opening are determined by the actual sprayer by means of a processor and auxiliary means.

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.

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.

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.

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 frame, a coulter connected to the frame and disposed to open a trench between the rows of plants, and at least one application member connected to the frame or to the coulter and disposed to apply fluid to a rhizosphere of the plants.

Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include calculating an amount of light originating from a light source sensed at a location in which an agricultural object is interposed between the light source and an image capture device, causing emission of an obscurant, and directing the obscurant to a region interposed between the light source and the agricultural object.

Described herein are implements and application units for placement of fluid applications with respect to agricultural plants of agricultural fields. In one embodiment, an application unit includes a frame to be positioned in operation between two rows of plants and a plurality of flexible members coupled to the frame in operation such that the plurality of flexible members guide a lateral position of the frame to be approximately equidistant from the two rows of plants based upon whether at least one flexible member of the plurality of flexible members contacts one or more plants of the two rows of plants. The plurality of flexible members include a plurality of fluid outlets for spraying crop input in close proximity to the rows of plants.

A robotic orchard spraying system having autonomous delivery vehicles (ADV), each autonomously delivering an amount of a premixed solution over a non-overlapping path verified by a forward-looking sensor, video, or both. Also, a mobile control center, configured to wirelessly inform the autonomous delivery vehicle of the path within the areas and to confirm that the autonomous delivery vehicle is following the path within the area. Additionally, a mapper vehicle generates the path within the area, the mapper vehicle being configured to communicate information about the path and the area to the command center. The mapper vehicle senses the path with a forward-looking LiDAR sensor, and senses the area with a GPS sensor. Moreover, a nurse truck has a reservoir of premixed solution for replenishing a tank of the ADV. ADVs and the control center communicate over a radio network, which may be a mesh network, a cellular network, or both.

A method of using a system to apply liquid over a selected area includes providing a source of liquid, a first tube for transporting liquid from the source through the system, a connector, a check valve and a spray device. The connector includes a projection extending into the first tube. The projection has an inlet in fluid communication with the first tube. The connector further includes an outlet and a passageway in fluid communication with the inlet of the projection and the outlet of the connector. The check valve has an inlet in fluid communication with the outlet of the connector and an outlet. The check valve is operable to permit the passage of liquid from the inlet to the outlet upon pressurization of the liquid above a threshold pressurization level. The method includes the steps of introducing an amount of liquid to be applied to the selected area from the source of liquid to the first tube at a pressure below the threshold pressurization level of the check valve and providing pressurized liquid through the first tube to pressurize the liquid in the first tube above the threshold pressurization level of the check valve, thereby transporting liquid from the first tube, through the connector and the check valve and through the spray device in response to pressurization of the liquid. The liquid may be ozonated water.

A system includes a fluid supply line, a plurality of nozzle assemblies positioned and oriented to spray portions of a target, and a plurality of electrically actuated valve assemblies configured to control fluid flow to the nozzle assemblies. The system also includes a controller connected in communication with the plurality of electrically actuated valve assemblies and configured to individually actuate the valve assemblies between a closed position and an open position. The controller is configured to receive an orientation of each nozzle assembly relative to the target and determine a duty cycle of each valve assembly based on the orientation of the respective nozzle assembly. The controller is configured to actuate each valve assembly based on the respective orientation to provide a desired fluid characteristic of the fluid emitted from the respective nozzle assembly.
