An agricultural work vehicle is provided with crawler travel parts, support platform frames, a front/back structure, an engine, a hydraulic pump, a tank frame, and an injection nozzle unit. The crawler travel parts travel so as to hold a plant therebetween in the left/right direction. The support platform frames are disposed as a left/right pair, respectively overlapping with the left/right crawler travel parts in plan view. The front/back structures each include a left frame, a right frame, and a coupling frame. The engine is disposed at the left or right support platform frame. The hydraulic pump is disposed on the same side, out of the left and right support platform frames, as the engine, and is driven by the engine. A hydraulic oil tank is located on the opposite side in the left/right direction from the left support platform frame where the engine is disposed, and stores hydraulic oil to be supplied to the hydraulic pump.

An unmanned aerial vehicle (UAV) for application of an active ingredient to agricultural crops comprises at least one liquid reservoir, at least one liquid application unit, a processing unit, at least one set of rotor blades, and a plurality of legs. The at least one liquid application unit is configured to receive at least one input from the processing unit. The at least one input is useable to activate the at least one liquid application unit. The UAV is configured to fly within an environment using the at least one set of rotor blades, land within the environment, and walk on the plurality of legs to a location to apply liquid from the liquid reservoir to at least one plant. A location to apply the liquid is determined based on image analysis of one or more image of at least one image of the environment.

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system may determine a first real-world geo-spatial location of the treatment system. The system can receive captured images depicting real-world agricultural objects of a geographic scene. The system can associate captured images with the determined geo-spatial location of the treatment system. The treatment system can identify, from a group of mapped and indexed images, images having a second real-word geo-spatial location that is proximate with the first real-world geo-spatial location. The treatment system can compare at least a portion of the identified images with at least a portion of the captured images. The treatment system can determine a target object and emit a fluid projectile at the target object using a treatment device.

A spray apparatus for a vehicle includes a processing unit with at least one image of an environment. The processing unit analyzes the at least one image to activate at least one chemical spray unit mounted on the vehicle. Air is blown by at least one air blower mounted on the vehicle into a first downward directed air flow with respect to the vehicle. Air is directed by at least one diverter mounted on the vehicle into a second downward directed air flow with respect to the vehicle. A chemical spray unit of the at least one chemical spray unit is positioned relative to one or more air blowers and is positioned relative to one or more air diverters such that ejected liquid chemical is at least partially entrained within the first downward directed air flow and is at least partially entrained within the second downward directed air flow.

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.

An insect suppression device, and further relates to a self-moving device, a charging station, and an automatic working system that are mounted with the insect suppression device are provided. The self-moving device moves in a working area, performs a working task, and includes: a body and a movement module that is mounted on the body and drives the self-moving device to move. The self-moving device includes: an insect suppression device, mounted to the body, and a control module, controlling the movement module to move and controlling the insect suppression device to work. The beneficial effects of the present invention are as follows: The self-moving device can move autonomously in the working area and perform an insect suppression task, and has a wide coverage area, flexible work, and high efficiency, so that automatic control can be implemented, thereby freeing a user from the harassment of insects.

A method of operating a fluid sprayer includes dispersing a first fluid selected from a group consisting of larvicide, adulticide, and a barrier repellant from the fluid sprayer with a first nozzle assembly at a first volumetric flow rate, replacing the first nozzle assembly with a second nozzle assembly, and dispersing a second fluid selected from the group from the fluid sprayer with the second nozzle assembly at a second volumetric flow rate different than the first volumetric flow rate.
