Provided is a method and device for adjusting a broadcast dosage, an unmanned aerial vehicle and a storage medium. Applied to the unmanned aerial vehicle for broadcast through a material taking device driven by an electric motor, the method particularly includes: receiving a calibration instruction including a calibration rotation speed and calibration duration, controlling the electric motor to run at the calibration rotation speed within the calibration duration to discharge a material to be broadcast; acquiring a flight parameter and an actual discharge amount of the material to be broadcast discharged by the material taking device within the calibration duration; determining an adjustment coefficient between a flight speed and a rotation speed of the electric motor according to the flight parameter and the actual discharge amount; and adjusting the rotation speed of the electric motor to adjust the broadcast dosage according to the adjustment coefficient.

A machine body side control device is configured to control an actuator based on information on a posture change of a machine body obtained from a machine body side sensor and information on a position of an implement relative to the ground surface obtained from an implement side sensor via an implement side control device.

A spreader with a material divider that is adjustable to change a stream of material which flows in an arbitrary manner to the centrifugal disk(s) described to achieve a desired symmetrical or asymmetrical spread pattern.

A method for planning spreading of a spreading material mixture with an agricultural spreading machine includes steps of: identifying individual components of the spreading material mixture, determining component-related setting parameters for the agricultural spreading machine for a planned spreading operation for several or all of the individual components of the spreading material mixture, and evaluating joint spreadability of the individual components of the spreading material mixture on the basis of the determined component-related setting parameters by a calculating device.

A method for determining setting recommendations for an agricultural spreader includes the steps of: determining an uneven spreading-material distribution in a usable agricultural area or an uneven nutritional status of plants in the usable agricultural area, determining an ideal balancing distribution of spreading material that balances out unevenness of the determined spreading-material distribution in the usable agricultural area or unevenness of the determined nutritional status of the plants in the usable agricultural area, and determining setting recommendations for the agricultural spreader for implementing a balancing distribution of the spreading material, wherein the balancing distribution approximates the ideal balancing distribution.

The invention relates to a method for detecting the influence of the inclination (α1-α4) of an agricultural spreading device (100, 102) on the distribution of the material to be spread, having the steps of: receiving discharge information on spreading processes of agricultural spreading devices (100) using an analysis device (10) and ascertaining a relationship between a dispensing point of material to be spread onto at least one distribution disc (104, 106, 108, 110) of an agricultural spreading device and the distribution of material to be spread, said relationship depending on the inclination of an agricultural spreading device, using the analysis device on the basis of the received discharge information.

A method and arrangement for storing and recalling of setting values of a vehicle (10) and/or implement (14) that can be used for agricultural purposes comprising the following steps: inputting of at least one setting value for an actuator (49) of the vehicle (10) and/or implement (14) by a user interface; transmitting of a command based on the setting value to a control unit (32, 34, 38, 48) standing in operational connection with the actuator (49); and storing of setting data based on the setting value in a memory (72) in order to recall the setting value on the user interface or another user interface as required, wherein the setting value is converted into setting data using meta data regarding technical properties of the vehicle (10) and/or implement (14), the setting data representing a physical measure of the adjustment of the vehicle (10) and/or implement (14) achieved by the actuator (49) based on the setting value, the measure calculated based on the meta data and the setting value, and the setting data stored together with the meta data.

An adaptable walk behind spreader for dispersing particulate material in different spread patterns. The walk behind spreader includes a spread control assembly configured to control flow of particulate material through first, second and third exit openings and onto a dispersing mechanism. The spread control assembly includes a first spread control member and a second spread control member. Movement of the first and second spread control members selectively inhibits the flow of particulate material through at least a portion of the exit openings, thereby altering the spread pattern of the particulate material dispersed from the spreader.

A spreader with a material divider that is adjustable to change a stream of material which flows in an arbitrary manner to the centrifugal disk(s) described to achieve a desired symmetrical or asymmetrical spread pattern.

Method for a centrifugal spreader to precisely spread particulate material across an entire field with increased application rate, swath width and driving speed by utilizing a tiered disk spinner arrangement fed by a conveyor and guided by a material divider and an adjustable chute moveable in rotation around the spinner disk to achieve a desired symmetrical or asymmetrical spread pattern.
