A system and method are provided for subvehicularly accessed treatment of ground surfaces about a rail track occupied by a rail vehicle. A mobile treatment unit having a propulsion mechanism for subvehicular passage between the rails occupied by the rail vehicle includes a dispensing portion for expelling a treatment material therefrom onto regions of the ground surface about the rails. The mobile treatment unit is maneuverable between the rails and maintains height clearance for unobstructed passage beneath the occupying rail vehicle. At least one sensor unit is coupled to the mobile treatment unit, which acquires environmental feedback data about the mobile treatment unit. A control unit is operably linked to the mobile treatment and sensor units, and receives the environmental feedback data. The control unit controls actuation of the mobile treatment unit responsive to the environmental feedback and/or a maneuver control command.

An agricultural sprayer assembly includes a wheeled carriage, a chassis, and a spray delivery system. The wheeled carriage has a number of adjustable support legs (e.g., four), each formed of hydraulically coupled and actuated upper and lower leg sections or members. The chassis is supported on the wheeled carriage, at an adjustable clearance height defined by the operational height of the support legs. The spray delivery system includes a spray boom coupled to a boom support, and an actuator coupled to the boom support and the chassis. The actuator is configured to adjust the height of the spray boom with respect to the clearance height of the chassis.

In one embodiment, a method of creating a protected field is disclosed. In one embodiment, the method includes directing a first flow of air around a target space, drawing the first flow of air in through a primary air intake vent to create a first flow field envelope. In one embodiment, a second flow of air is directed within the first flow field envelope.

An intelligent air-assisted spraying device for orchards includes a traction mechanism, a spaying system, a collecting system, and a processing-controlling system. The traction mechanism is provided with a spray tank. The spaying system includes a main body connected to the spray tank and multiple spraying tubes, first ends of the spraying tube are communicated with the main body, and second ends of the spraying tubes are capable of rotating. The collecting system is configured to collect a contour and a volume of the canopy, and branch and leaf density of a fruit tree. The processing-controlling system is configured to obtain multiple spraying areas, calculate an air outlet angle of each spraying tube, and control a rotation of the second end of each spraying tube according to the air outlet angle. The device can adjust the spraying direction of each spraying tube, and the quality of pesticide application can be improved.

A composition for forming an aerosol, an aerosol sprayer for insect pest mating disruption, and a method for insect pest mating disruption, thereby reducing disadvantageous effects caused by falling to a ground surface and oxidative decomposition of the sprayed particles. More specifically, the composition including an aerosol stock solution containing an aliphatic linear aldehyde having 10 to 20 carbon atoms and a non-alcoholic diluent, and a propellant, wherein a weight ratio of the aerosol stock solution to the propellant is from 45:55 to 65:35; the sprayer including the composition and a pressure resistant container for enclosing the composition therein, wherein sprayed particles at a spray travel distance of 15 cm have a median particle size (Dv50) at 25 C. of from 35 to 65 m by a volume-based cumulative particle size distribution and; the method using the aerosol sprayer; and the like.

Disclosed is a self-powered vehicle utilized in the field of agriculture, property maintenance, landscaping for use with estate or condominium ground maintenance. It is used for spraying pesticides, herbicides, fertilizer and the like and also for application of similar products in granular form, but further serves as a maintenance platform around a larger industrial facility. Its main payload area is also used for cargo and product transport. It offers high mobility and maneuverability. It is powered with gearhead motors connected to its drive wheels with batteries as its power source. They are charged by an engine driven generator all of which is mounted on the vehicle. Directional control is achieved by the use of a motorcycle handle bar in combination with rotary potentiometers. Each potentiometer controls pulse width of a pulse width modulator thereby controlling the speed of a gearhead motor. The vehicle is optionally a walk behind device but may be provided with a seat behind the handle bar.

The present disclosure relates to a system and method for spraying one or more target objects. A primary blower system is adapted to create a relatively isolated field of circulating air by creating a primary air stream around the field of circulating air. A secondary blower system is adapted to circulate air within the isolated field by flowing a secondary air stream in directions contrary to the primary air stream. A chemical spray comprising liquid, aerosol droplets, particulate matter, or the like may be emitted into the circulating air within the field and thereby deposited on target objects within the field. Embodiments of the present disclosure may be used for agricultural, automotive, aerospace, and other applications to emit, contain, and/or recapture a spray.

A spray jet discharging device of long range, whose function is based on the production of a powerful air stream with liquid droplets dispersed therein, the maximum velocity of the spray jet being at least 300 km/h. The air stream is produced by a centrifugal fan with a spiral housing (1). The device is mainly used for fire extinguishing. It may be mounted at fixed points or on land vehicles via a suitable support for the fan, which enables both rotation of the spray jet beam in the horizontal plane, and changing of its inclination angle in the vertical plane. It may be remotely controlled (10) or manually operated (60). There is also a version of the device for aerial fire-fighting operations (90), configured to be suspended from an aircraft, e.g. a helicopter, and a device for portable use (1 10), which can be carried by a fireman.

A system for applying agricultural fluid to a target includes a controller communicatively connected to valve assemblies and configured to control at least one operating parameter of each valve assembly, and a portable electronic device connected in communication with the controller. The portable electronic device includes a user interface. The portable electronic device is configured to retrieve a stored user profile including at least one prestored value that relates to a physical characteristic of the system or an operating parameter of the system, and populate at least one user input field of the user interface with the at least one prestored value. At least one of the controller and the portable electronic device is configured to retrieve the stored user profile and determine the at least one operating parameter of each valve assembly based on the physical characteristic of the system or the operating parameter of the system.
