An agricultural chemical spraying drone with improved safety is provided. The drone includes an altitude measurement sensor and a speed measurement sensor and controls not to exceed an altitude restriction and a speed restriction of an airframe by using a flight controller. The sensors are desirable be combination of multiple types. Particularly, the altitude is desirably measured by a GPS during take-off and by a sonar during chemical spraying. Weight of the airframe is measured from time to time, and the altitude restriction and the speed restriction may be adjusted according to the weight.

The invention relates to a device for cleaning a vehicle window that includes a foam generator that is configured to draw in air and a cleaning fluid (L) and mix them and at least partially convert them into a foam form; and further includes, a regulating means for regulating the air flow drawn in by the foam generator and a control unit that is configured to control an air flow regulating means on the basis of at least one parameter.

Wind speed, wind direction, and field boundary information are detected and used to identify a monitor area indicative of a likely overspray condition. Control signals are generated to obtain information from a sprayed substance sensor, in the monitor area. When an overspray condition is detected, an overspraying signal from the sprayed substance sensor indicating the detected overspray condition is received and overspray processing is performed, based upon the received overspray signal.

A multi-axis linkage for use with a collapsible boom of an agricultural vehicle is disclosed. The collapsible boom includes a first boom segment having a first truss and a second boom segment having a second truss. The multi-axis linkage includes a first linear motor, a second linear motor, and a multipoint winged link. The first linear motor has a piston rod. An end of the piston rod is coupled to the first truss. The second linear motor has a second piston rod. An end of the second piston rod is coupled to the second truss. The multipoint winged link connects to the first linear motor, the second linear motor, the first boom segment, and the second boom segment.

An agricultural vehicle includes a chassis, wheels supporting the chassis for moving the vehicle, an application system supported by the chassis and including a product tank storing a volume of agricultural product for delivery onto an agricultural field, and an application boom configured to deliver the agricultural product to the agricultural field. The application boom includes a boom arm segment having a longitudinal tube, an elongated structure coupled to the longitudinal tube, and an elastomeric bonding material affixing the longitudinal tube and the elongated structure.

An intelligent, automated system for loading agricultural product application equipment is provided in which a control system can determine a necessary amount of product for completing a field operation and can automatically couple with a tendering system to receive such product at an optimal time and location. The control system can determine a current amount of product, a projected amount of product necessary to complete a field operation and a refill amount of product from the current amount and the projected amount, then transmit the refill amount to the tender. The control system can further determine whether a position of the equipment relative to the tender is within a threshold, and whether an intake coupler of the equipment is connected to a supply coupler of the tender, and can control valve(s) to open and close channel(s) for loading fluid into the storage tank.

A boom suspension assembly for an agricultural sprayer having a chassis, a lift arm assembly mounted to the chassis, and a boom support frame pendulously suspended from the lift arm assembly. Springs and dampers between the chassis and the boom support frame control pitch and yaw movement of the boom support frame away from a neutral position. The lift arm assembly, boom support frame and dampers provide a four-bar linkage which maintains the boom support frame in a steady alignment when raised and lowered.

An agricultural vehicle comprises a left frame and a right frame. A left wheel is rotatable with respect to the left frame and a right wheel is rotatable with respect to the right frame. A first leg extends upward from the left frame and a second leg extends upward from the right frame to connect the legs to the beam. A data processor estimates a reference point on or below the vehicle and an angular orientation or attitude of the beam relative to the reference point based on positions of location-determining receivers associated with the beam. An upper carriage is laterally movable along the beam. A lower carriage is suspended from the upper carriage by a plurality of vertical supports, such that a target lateral position of the upper carriage establishes an actual lateral position of the lower carriage.
