Abstract

Abstract Device and procedure for seed counting in a seed drill comprising a seed container and a plurality of seed nozzles connected with connecting conduits (4, 5), and an air flow source adapted to create an air flow to conduct crop seed in the form of seeds from the seed container to the seed nozzles. A detection entity (18) is arranged at the connecting conduit (4, 5), and comprises two light sources (24, 30) adapted to send parallel light beams essentially perpendicular to the direction of flow in the connecting conduit (4, 5). Two line cameras (28, 34) are arranged at the opposite side of the connecting conduit (4, 5) having the aim of sensing the light level from the two light sources (24, 30). The line cameras (28, 34) are connected to a control entity (20) adapted to calculate the number of seeds that pass the line cameras (28, 34) by comparing the light level across the width of the line cameras (28, 34) over time. (Figure 2)
