An agricultural spraying machine which is supported on the ground and is movable in a forward direction over a field, the agricultural spraying machine comprising: a chassis; a sprayer linkage, the sprayer linkage configured with a middle segment movably supported on the chassis; a pair of booms arranged on respectively one side of the middle segment and which are pivotable by respectively at least one actuator in relation to the middle segment about an axis extending in the forward direction; a control device configured to receive a signal from at least one sensor associated with the pair of booms and generate a control signal, the control device receiving the signal from the at least one sensor as an input variable and wherein the control device receives the signals provided by the at least one sensor in respect of the relative position of the pair of booms in relation to a field contour; and wherein an adjustment of the at least one actuator occurs using control signals from the control device, the control signals being respectively dependent on the input variables and configured to drive the actuator on with a view to maintaining the positions of the booms in a desired position above the field contour wherein due to the mechanical coupling of the pair of booms by the middle segment, also results in a movement of other respective booms.

Agricultural spraying machine having a spraying linkage

An agricultural field sprayer () includes an electrically driven pump () locatable directly under sprayer fluid tank for conveying the fluid from the tank to a supply line. A return line () connects the pump () to the tank (), and a sprayer line () connecting the pump () to an application assembly (). The return line () and the sprayer line () include electrically operated control valves (), and an electronic control system () operates the motor () and the control valves () as a function of different variables including field sprayer speed and sprayer fluid characteristics. The valve and motor controls and an additional valve-controlled return line facilitate numerous operational modes including tank fill, rinse, recirculation, spray, partial width spray, and stop modes.

Agricultural field sprayer and process for its operation

A tank for an agricultural field sprayer having a fill region and a first closure. To avoid costly connections for lines at the tank and to reduce the cost of manufacture of the tank, the first closure can be rigidly connected to the tank and provided with an opening uncovered by a second closure. The connections of the first closure are arranged on a region configured as a connecting region, so that an access to the fill region is made possible by the second closure, even if the sprayer is in operation, particularly in a washing-in operation or in a circulating operation.
