According to some embodiments, an oscillating sprinkler system is provided that includes: a central tubular portion having at least one row of flexible nozzles; a cam plate located inside a peripheral wall of said central tubular member, said cam plate having a plurality of cam slots for adjusting positions of said flexible nozzles upon rotation of said cam plate within said peripheral wall; and said peripheral wall including a window via which an edge of said cam plate is observable during rotation of said cam plate such as to designate an extent of angular displacement of the nozzles based on the positioning of the cam plate within the window.

An electrically powered, portable fluid dispenser that includes a main housing and extendable wand that when used in conjunction with an electric motor, a self-feeding tentacle pumping spinning element, tentacle feed tube, and focusable vibrating backstops, is able to pump, atomize, and dispense, low and high viscosity fluid with controlled directionality and droplet size.

According to one embodiment, there is provided a breakaway hinge for an expandable boom on an agricultural vehicle. The boom includes a first and a second section combined in a manner to allow the second section to move with respect to the first section when the second section encounters an obstruction. A breakaway hinge is provided between the first and the second section, and includes a first pivot member attached to the first section at an angle with respect to a vertical line and a second pivot member attached to the second section at an angle with respect to the vertical line. A connecting member holds the first pivot member with respect to the second pivot member.

A surface treatment assembly for treating a contoured surface includes a surface treatment array formed from a plurality of base structures, each base structure operably coupled to a first phalange structure and a first phalange structure first end. A second phalange structure operatively coupled to each first phalange structure and a phalange joint disposed between each first phalange structure and each second phalange, thereby forming a finger structure. Moreover, at least one applicator head is coupled to a second phalange structure second end of each finger structure and configured to treat the contoured surface. A base structure actuator and a phalange joint actuator operatively coupled to and configured to manipulate the first phalange structure and the second phalange of each finger structure to adjust the surface treatment array relative to the contoured surface.

A control apparatus for a broadcast spreader includes a gate adjustment dial mounted on, and generally coaxial with, a handle portion of a handle assembly of the spreader. Rotation of the gate adjustment dial in a first direction causes an increase in a current maximum discharge rate of the spreader and rotation of the gate adjustment dial in a second direction causes a decrease in the current maximum discharge rate of the spreader.

The central-pivot sprinkler contains a central-pivot sprinkler and a controllable variable spray gun. The controllable variable spray gun has a spray gun main body (2), a booster pump (7), and a spray gun connecting pipe (16). A water inlet of the booster pump (7) is communicated with a sprinkler pipe (15) of the central-pivot sprinkler. A water outlet of the booster pump (7) is connected to a water inlet of the spray gun main body (2) by means of the spray gun connecting pipe (16). The forepart of the spray gun main body (2) is provided with a spray nozzle (12). The tail portion of the spray gun main body (2) can be mounted at the end of a crossing-body (1) of the central-pivot sprinkler by means of a spray gun horizontal-rotation mechanism.

Rotating spray systems and related methods for enhancing spray performance can include one of more rotating spray assemblies formed of a plurality of individual, linear distribution manifolds to define a rotary cage. The rotary cage is fluidly coupled to a rotating distribution block on a distribution valve, with each linear distribution manifold being fluidly coupled to one of a plurality of distribution conduits defined in the rotating distribution block. The distribution valve further includes a fixed distribution block having an arcuate aperture defined therein. The rotating distribution block rotates relative to the fixed distribution block to individually and sequentially engage each distribution conduit with the arcuate aperture. When the individual distribution conduits are fluidly engaged with the arcuate aperture, pressurized fluid supplied to the distribution valve is supplied to the corresponding linear distribution manifold for spraying by one or more spray nozzles fluidly connected to each linear distribution manifold.
