A method for determining a mass flow composed of bulk material, in particular grain, which is conveyed by means of a continuous, circulating conveyor, having planar conveyor elements, from a lower bulk material receiving area to a higher bulk material delivery area, in which the bulk material delivered by the conveyor is deflected by a guide surface disposed in the bulk material delivery area toward a measuring device, wherein the mass flow is determined by the measurement of a resulting force (F_G) exerted on a sensor surface of the measuring device, wherein at least two parameters having an effect on the force measurement, in particular parameters independent of bulk material properties, are compensated for. A control and regulating device for executing the method for determining a mass flow composed of bulk material is also provided.

Method for determining a mass flow composed of bulk material

A measuring device is provided for measuring a mass flow composed of bulk material, in particular grain, in a continuous, circulating conveyor enclosed in part by a housing, having planar conveyor elements, which conveys the bulk material from a lower bulk material receiving area to a higher bulk material delivery area. A substantially circular movement course is imposed on the bulk material delivered by the respective conveyor element in a substantially radial direction of an inner surface of a cover section of the housing by a guide surface formed in the upper region of the conveyor. The bulk material is deflectable toward a sensor surface of the measuring device. At least the sensor surface of the measuring device is disposed in the upper region of the conveyor such that there is a tangential course in the transition from the guide surface to the sensor surface.

A harvester includes a measuring device for detecting a grain number of a crop flow, in which a sensor of the measuring device detects via a measuring signal kernels impacting an impact surface of the measuring device, and a processing unit of the measuring device is arranged to detect and calculate the grain number by using the measuring signal, wherein the rising edges of the measuring signal are recorded and form a measurement for the grain number. Furthermore, the measuring device for detecting a grain number and method for detecting a grain number are also provided.

A method of determining crop parameters in an agricultural harvester has the steps of determining at least one crop parameter during a working process with a compacting device which is fillable with a crop probe, and using for determining the at least one crop parameter of the crop probe depending on at least one defined compression of the crop probe produced by the compacting device.

An apparatus for automatic adjustment of a transfer device on an agricultural harvesting machine includes a sensor for determining the current position of the transfer device; means for adjustment of the transfer device; a navigation device located in the harvesting machine for determination of a first and a second navigated position in a field; and an electronic analyzer wherein the electronic analyzer automatically adjusts the transfer device through the means for adjustment as a function of the current position of the transfer device and the first and second navigated positions of the harvesting machine.

The invention describes a device and a method for finding an actual or a virtual reference point on mobile equipment or implement. In agricultural technology the control and mapping of working processes as a function of the instantaneous position of the equipment on the field is gaining more and more importance. With increasing precision of the navigation systems, further possible applications are opening up. As a result of the higher precision of satellite navigation systems, the changes in inclination and direction of the equipment also have an effect on the measured position of the equipment. This effect is of the order of magnitude of the precision of modern-day navigation equipment and is therefore also taken into consideration in position finding according to the invention. For this the inclinations and direction of the machine referred to a predefined neutral position are determined and also calculated when finding any reference position. With the aid of the invention the exact position values of the navigation antenna can be converted to a reference point, which is important for the working process. This reference point is located outside the unit of mobile equipment. In an advantageous embodiment, when determining the position of the reference point, further working parameters such as speeds or positions of implements are taken into consideration or the position of the reference point is regulated with the aid of dynamic parameters such as for example the speed of travel.
