A harvesting machine has a crop tank and a conveyor screw inside the tank which extends from a material inlet opening on a wall of the crop tank into the interior of the crop tank. The conveyor screw comprises at least one proximal portion adjacent to the material inlet opening and one distal portion spaced apart from the material inlet opening at least by the proximal portion. The proximal portion and distal portion are rotatable around conveying axes running in different directions. The conveyor screw can be operated in a work position in which the conveying axis of the distal portion is oriented to be steeper than the conveying axis of the proximal portion.

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.
