A sprayer system is provided for a work machine that includes a boom, a fluid source, and an air source. The sprayer system includes a spray device configured to selectively apply a fluid from the fluid source to an agricultural crop. A retractable arm includes a first arm segment, a second arm segment, a first hinge joint positioned such that the first arm segment is selectively foldable relative to the boom, and a second hinge joint positioned such that the second arm segment is selectively foldable relative to the first arm segment. An actuation assembly coupled to the retractable arm selectively folds and unfolds the first arm segment relative to the boom at the first hinge joint and the second arm segment relative to the first arm segment at the second hinge joint based on air pressure from the air source.

After completion of a preceding painting in a preceding painting area, by an action of a preceding painting robot, a painting object (object to be painted) is caused to be held together with a holder by a transfer section near two painting areas. In succession, with maintaining connection between the painting object and the holder, connection between an arm leading end portion of the preceding painting robot and the holder is released. Thereafter, by an action of a subsequent painting robot, an arm leading end portion of the subsequent painting robot with keeping its connection to the painting object is connected to the holder held to the transfer section. With this, in the course of transfer of the painting object between the painting robots for displacing the painting object relative to a spraying means, a relative positional relation between the arm leading portions of the painting robots and the painting object can be maintained same.

A mist generating apparatus is provided for suppressing foreign material from becoming airborne prior to an application of a surface coat or treatment to a substrate. The assembly includes a frame assembly that may include a base mount and an intermediate mount movably coupled to the base mount. The apparatus includes an extension assembly movably coupled to the frame assembly and selectively positioned between a retracted position and an extended position. A manifold is coupled to the extension assembly, and the manifold is in fluid communication with a volatile liquid. The apparatus includes a spray nozzle in fluid communication with the manifold. The spray nozzle is configured for directing a mist of the volatile liquid to a portion of the substrate for at least temporarily suppressing foreign material.

An Automatic (Auto) Photovoltaic (PV) Solar Panel Washer comprising a main carrier joined by a connecting member to the main mast. A main hydraulic cylinder system comprising one or more hydraulic cylinders and connector arrangement on the main mast raises the main mast up or pushes it down, activating the connecting member, thereby raising or lowering the main carrier. The positioning hydraulic cylinder determines the angle of the main carrier by pushing one end down or bringing it up. A rotating device assembly rotates the main mast and main carrier clockwise or counterclockwise from rest position over its stationary post. The main carrier comprises a rigid frame with attachments including a cleaning assembly consisting of air cylinders with cleaning wiper systems, tracks for the air cylinder shafts, wash material pipes with spray devices attached, rinse material pipes with spray devices attached, and compressed air drying pipes with air spray devices.

Swivel shower including a base body, a swivel body including a shower outlet and held on the base body for swivel movement about a swivel axis between a first swivel body end position, constituting a rest position, and a second swivel body end position, constituting an operating position, a shower fluid inlet for supplying a shower fluid, and a swivel drive for driven swiveling of the swivel body, wherein the swivel drive includes a slide piston capable of being pressurized by a fluid pressure of the supplied shower fluid, which piston is arranged for translational movement between a first piston end position, corresponding with the first swivel body end position, and a second piston end position, corresponding with the second swivel body end position. Illustratively, the slide piston is arranged with a translation directional component in parallel to the swivel axis, and/or the swivel drive includes a transmission element in the form of a slotted guide mechanism between the slide piston and the swivel body, wherein the transmission element transmits the translational movement of the slide piston into a swivel movement of the swivel body, and/or the shower outlet in the rest position of the swivel body is swiveled away from a visible face of the swivel shower, and a swivel angle stroke from the first to the second swivel body end position is at most 90?.

A liquid medium delivery device has: first and second rigid pipes configured to receive flowing liquid medium from a pump. The first rigid pipe has a first curved portion. The second rigid pipe has a second curved portion. The curved portions are at least partially nested. An actuator is connected to the first rigid pipe or the second rigid pipe or both the first and second rigid pipes. The actuator is operable to move either the first rigid pipe or the second rigid pipe so that either the first curved portion or the second curved portion moves along a common arc of both the first curved portion and the second curved portion. The liquid medium delivery device has an outlet through which liquid medium, for example liquid manure, can be pumped.
