A control system for a suspended boom sprayer of a vehicle comprises: first and second sensors each configured to be disposed on respective first and second boom wings of the suspended boom sprayer and to provide an output responsive to a rotation of the first and second wings caused by a disturbance torque; a processor, configured to determine a differential acceleration between the first and second wings based on the outputs of the respective sensors, and to determine the disturbance torque corresponding to the differential acceleration; and at least one actuator, controllable to move one or both of the first and second wings in order to counter the disturbance torque.

An intelligent pesticide spraying robot self-adaptive to terrain of mountain land is provided. Walking mechanisms are respectively connected to both side ends of a chassis. A pesticide spraying mechanism includes rotary drive mechanisms respectively connected to both sides of the rear end of the chassis, telescopic spray boom mechanisms correspondingly connected to the rotary drive mechanisms, rotary nozzle mechanisms correspondingly connected to the telescopic spray boom mechanisms, a liquid pesticide storage box fixed to the top of the chassis, a first water pump fixed in the liquid pesticide storage box, and first water pipes in communication with the first water pump and the rotary nozzle mechanisms. A control chip of a control identification mechanism is communicatively connected to the walking mechanisms, the rotary drive mechanisms, the telescopic spray boom mechanisms, the rotary nozzle mechanisms, the first water pump, a front-end camera, side-end cameras and ultrasonic sensors respectively.

The present invention generally relates to methods of cleaning residual pesticide from an agricultural vessel, and to kits and compositions useful for the practice of such methods.

A probe assembly for a closed transfer system is provided. The probe assembly includes a base having a base air inlet, a probe having a base end and a probe end, at least one primary valve positioned at the probe tip, and at least one secondary valve. The probe defines a hollow air channel extending from the base end to the probe end including a probe tip, the base end being coupled to the base such that the hollow air channel is in fluid communication with the base air inlet and the probe tip. The at least one secondary valve is positioned at the base air inlet and configured to selectively allow air into the hollow air channel.

This collection panel for an agricultural sprayer forms a hollow box comprising an air inlet opening and openings or pre-openings capable of receiving pulsed-air spraying assemblies.

An agricultural product application implement includes a system and method for indicating an amount of fluid stored. A pressure transducer installed at the sump of a fluid tank electronically measures and displays a fluid depth. Instrumentation, such as an instrument cluster unit for the implement, is programmed via software to convert the voltage output of the pressure transducer to a volume measurement displayed in the operator's line of sight. Software within the instrument cluster unit for self-calibrating accounts for varying densities of different chemical solutions. The pressure transducer is used in conjunction with a transfer medium to prevent corrosive chemical solutions from contacting the pressure transducer.

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.

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.

Disclosed is a plant protection and management system for a center pivot and linear irrigation system. In the plant protection and management system, the movable platform is configured to provide at least one of an application unit, a seeding-fertilizer spreader unit or a monitoring unit. The application unit is configured to spray agriculture chemicals or fertilizers on crops. The seeding-fertilizer spreader unit is configured to sow seeds of crops. Further, the monitoring unit is configured to monitor crops and collect status data of the crops or status data of environment. According to different requirements on agricultural production, at least one of the application unit, the sowing unit or the monitoring unit can be selectively arranged on the movable platform so as to meet various requirements on plant protections and managements in the process of agricultural production.

A liquid distribution system for a crop sprayer includes a product tank configured to contain a liquid, a pump, and nozzles carried by a boom. The product tank has a fluid inlet, and at least one water quality sensor is configured to detect a water quality property of liquid entering the product tank through the fluid inlet. Methods of operating a crop sprayer include measuring a first water quality property of fresh water entering a product tank, measuring a second water quality property of rinsate formed from the fresh water within the product tank, removing the rinsate from the product tank, and if a difference between the second water quality property and the first water quality property is greater than a preselected threshold, forming a second rinsate in the product tank.
