A farming machine includes one or more image sensors for capturing an image as the farming machine moves through the field. A control system accesses an image captured by the one or more sensors and identifies a distance value associated with each pixel of the image. The distance value corresponds to a distance between a point and an object that the pixel represents. The control system classifies pixels in the image as crop, plant, ground, etc. based on the visual information in the pixels. The control system generates a labelled point cloud using the labels and depth information, and identifies features about the crops, plants, ground, etc. in the point cloud. The control system generates treatment actions based on any of the depth information, visual information, point cloud, and feature values. The control system actuates a treatment mechanism based on the classified pixels.

Aspects of the technology described herein provide a system for improved control and monitoring of a movable tower in an irrigation system. A computer controller associated with a tower of an irrigation system receives an indication of parameter modification. The system is then able to change parameters at a component of the tower control system based on the received parameters. The system stores the current drive value at a station to control drive. If the stored drive value is above a threshold level, a drive signal is provided to a motor. The system is operable to selectively apply a drive signal at a tower. The system provides the ability to digitally modify a threshold that is used in a machine run-mode to operate the motor at a tower.

A sprinkler nozzle is configured for a sprinkler positioned at a distal end of a center pivot irrigation system. The sprinkler nozzle includes a connection part securable to the sprinkler, and a nozzle opening downstream of the connection part. A nozzle opening downstream of the connection part is part-toroidal shaped and partially blocked or skewed to control water flow to portions of the deflector plate according to a desired wetted area. The part-toroidal shape spans an arc less than 360 degrees. The nozzle enables a custom designed water application to complement the other sprinklers that are on the pivot and can be shaped to also apply water a distance beyond the end of the pivot pipe to match the application rate of the sprinklers along the pivot pipe.

A spray bar injector including a spray bar defining a longitudinal axis and including a fluid inlet and a plurality of spray outlet orifices spaced apart longitudinally in a direction along the longitudinal axis. A check or spray valve is operatively connected to each spray outlet orifice. A master valve is in fluid communication with the fluid inlet, operatively connected to divert flow from the fluid inlet into a first passage and block flow into a second passage in a first position to open the check valves and issue a spray from the spray outlet orifices, and to divert flow from the fluid inlet into the second passage and block flow into the first passage in a second position to close the check valves and block issue of spray from the spray outlet orifices.

A supply tube assembly for measuring a liquid agricultural product application rate. An upstream portion of a supply tube has an upstream portion outlet end. A downstream portion has a downstream portion inlet end. The sensor body assembly includes a sensor body, a first sensing plate, and a second sensing plate. The sensor body has a sensor inlet end positioned to receive an inlet flow of the liquid agricultural product from the upstream portion and a sensor outlet end positioned to receive an outlet flow of the liquid agricultural product. The sensor body is an enclosure having a cross sectional area larger than the cross sectional area of the upstream portion of the supply tube and the downstream portion of the supply tube. Electronic components are configured to measure the liquid agricultural product application rate between the first sensing plate and the second sensing plate.

The present disclosure provides an irrigation system for crop irrigation, and especially a centre-pivot irrigation system. The system comprises: a pivot assembly comprising a frame supporting an inlet pipe assembly for inlet of water from a water supply to the irrigation system, and a span assembly for connection to the pivot assembly to extend radially therefrom across a field. The inlet pipe assembly comprises an upper pipe segment and a lower pipe segment. The upper pipe segment is mounted in the frame for rotation about a pivot axis relative to the lower pipe segment. The span assembly comprises a distribution pipeline for fluid connection with the inlet pipe assembly to convey the water along the span assembly for distributing the water to a plurality of sprinkler heads located along the span assembly for applying the water to the field.

A spray boom for spraying a fluid on a target includes a boom frame and a spray section coupled to the boom frame. The spray section includes a spray pipe configured to be fluidly coupled to a fluid source and a nozzle coupled to the spray pipe and configured to be fluidly coupled to the fluid source. An actuator is coupled at one end to the boom frame and at an opposite end to the spray section. The actuator is controllably extending and retracting to move the spray pipe and nozzle between a raised position and a lowered position. A trip assembly is coupled between the boom frame and actuator for biasing the spray section to a biased position in which the actuator and nozzle are substantially perpendicular to the underlying surface.
