STRUCTURE OF THE MEASURING DEVICE FOR MEASURING THE MASS FLOW OF BULK MATERIAL AND THE GRAIN-HARVESTING COMBINE Russian patent published in 2021 - IPC A01D41/12 A01D61/04 G01F1/20 G01F1/30 

FIELD: agriculture.

SUBSTANCE: grain-harvesting combine has an infinitely rotating transporting device containing planar transport elements, which is partially encircled with a case and which transports bulk material from the area of bulk material grabbing located below to the area of bulk material unloading located above. Bulk material unloaded from the corresponding transport element essentially in a vertical direction by means of a guide surface located in the area of bulk material unloading can move essentially on a circular trajectory and thus decline in the direction of a sensitive surface of the structure of the measuring device for measuring mass flow of bulk material, in particular grain crops. The structure of the measuring device contains the sensitive surface located in the upper part of the transporting device so that in the area of transition from the guide surface to the sensitive surface the flow has tangential orientation in the circumferential direction, i.e. the sensitive surface comes into contact with the movement trajectory of the mass flow. The guide surface is a part of a separate guide section adjacent to a roof section in the area of bulk material unloading forming tangential transition. The distance between the free end of the corresponding transport element and the roof section encircling the transporting device in the area of bulk material unloading in the transport element position, in which there is a distance to the roof section, is selected in such a way that it is possible to fully unload bulk material located on the transport element and provide for even flow input on the sensitive surface.

EFFECT: increased accuracy of flow measurement of transported material is provided.
