A traveling vehicle includes a controller to control a posture of a work machine via a connector. The controller observes whether a farm field surface on which the traveling vehicle travels and the work machine maintain a predetermined positional relationship therebetween, and controls the posture of the work machine when a positional relationship between the farm field surface and the work machine changes from the predetermined positional relationship, so that the positional relationship thus changed is reset to the predetermined positional relationship.

A boom height control system for an agricultural crop sprayer includes a spray boom and an actuator arranged to adjust a position of at least a portion of the spray boom in response to a position adjustment command. A speed sensor is provided to measure a forward speed of the sprayer and generate a speed value. A position sensor is provided to measure a current position of the spray boom portion and generate a current position value. A controller is in communication with the speed sensor, the position sensor and the actuator. The controller is configured to generate the position adjustment command based upon a target position value, a current position value and a speed value.

A mobile device for storing and supplying multiple liquid fertilizers, comprising a housing, enclosing: two or more storage units, each suitable for storing a liquid fertilizer, wherein each storage unit is provided with a storage unit level measurement system, a storage unit filling system and a storage unit venting system; a safety drain liquid fertilizer storage, comprising at least two separate collectors for the separate containment of spilled liquid fertilizer; a dosing and controlling system; and wherein the housing is equipped with a connection for the input of a water flow, at least two connections for the output of liquid fertilizer, and an output for venting gasses.

A protective cover in combination with a liquid fertilizer system prevents leftover plant matter from damaging a tube carrying liquid fertilizer, particularly when the field is no-till. The protective cover is installed, without modification to the planter or liquid fertilizer system, using a mounting flange that is attached to a leading wall through a standoff wall. A bottom angled wall is located opposite the standoff wall. Side walls extend from the leading wall and cooperate with the bottom angled wall to form a protective area for the liquid fertilizer tube. When in use, the leftover plant matter contacts the protective cover instead of the liquid fertilizer tube. The protective cover may include access gaps between the side walls and the standoff wall and/or bottom angled wall, depending on the configuration of the liquid fertilizer system.

A system for spraying plants comprises a location-determining receiver for estimating a position of a sprayer with respect to one or more rows of plants. A distance sensor is arranged to measure a distance between a nozzle assembly and a plant row segment. A guidance module is adapted to align the nozzle assembly with a target path between the rows of plants, such as a centered path between the rows, or offset between the rows of the plants. A first nozzle is targeted toward a first zone with respect to the plant row segment based on a first spray pattern of the first nozzle. A second nozzle is targeted toward a second zone with respect to the plant row segment based on a second spray pattern of the second nozzle. A nozzle selection module for selecting automatically a first nozzle or a second nozzle based on maximum coverage of a target zone around the plant segment based on the first zone, the second zone, and the measured distance.

The invention relates to an agricultural apparatus (1) for spreading material, such as fertilizers, plant protection products, or seed, comprising a distributor linkage (10) which can be folded on both sides, comprising a central part (11), where the central part (11 ) is connected in a rotationally fixed manner to the agricultural apparatus (2 ), two intermediate frames (12a,b) connected to the central part (11) in particular by joints, two lateral booms (13a,b) connected to the respective intermediate frames (12a,b), and a damping assembly (19) for damping motions of the first boom (13a) and the second boom (13b) in the direction of travel of the agricultural apparatus (1), where the damping assembly connects the intermediate frames (12a,b) to one another in particular independently of the central part (11), or where the damping assembly (19) connects the respective intermediate frames (13a,b) to the central part (11).

A drip irrigation treatment device, which comprises a water storage tank, wherein a partition plate is arranged in the water storage tank and divides the interior of the water storage tank into a conveying cavity and a purifying cavity, one side of the conveying cavity and one side of the purifying cavity are jointly connected with a first water conveying mechanism, a protection box is arranged on one side of the water storage tank, a filter box is arranged in the protection box, one side of the upper end of the protection box is connected with a sewage conveying pipe, the lower end of the sewage conveying pipe corresponds to the filter box, a filtering mechanism is arranged in the filter box, a buffer moving mechanism is arranged on the periphery of the filter box, and a rotating mechanism is arranged on one side in the protection box.

A closure assembly includes a tank opening flange that surrounds a tank opening of a supply tank and a tank lid that covers the tank opening. The tank lid is operable between open and closed positions. A compression seal is attached to an underside of the tank lid and is disposed between the tank opening flange and the tank lid when the tank lid is in the closed position. A pair of guides are attached to opposite sides of the tank opening flange wherein each of the pair of guides defines a track opening to receive a plurality of sliding mechanisms attached to the tank lid. The track opening guides the sliding mechanisms and the tank lid around the tank opening flange such that the compression seal does not engage the tank opening flange when the tank lid is operated between the closed and open positions.

An agricultural system can include a boom assembly supporting one or more nozzle assemblies there along. A boom adjustment system can be operably coupled with the boom assembly. A sensing system can be configured to capture data indicative of one or more application variables. A computing system can be communicatively coupled to the boom adjustment system and the sensing system. The computing system can be configured to receive, from the sensing system, the data associated with the one or more application variables, calculate a spray quality index based on the data associated with the one or more application variables, and generate an output to change a position of the boom assembly through the boom adjustment system based at least in part on the calculated spray quality index deviating from a defined range.
