The invention discloses an intermittent linkage type crop harvest yield monitoring device, which has the advantages of high measurement precision, good safety and high reliability. The intermittent linkage type crop harvest yield monitoring device comprises a measurement box body and a feed hopper, the feed hopper is arranged at a feeding opening above the measurement box body, and a material distribution plate is rotatably arranged at the inner upper part of the measurement box body and corresponds to the corresponding feeding opening; and the measurement box body is symmetrically divided into a left measurement room and a right measurement room by a measurement room clapboard arranged in the measurement box body, the lower part of each of the left measurement room and the right measurement room is provided with a weighing turner which can rotate around a turning driving shaft serving as a hinge joint, a material distribution driving shaft and two driving ends of the turning driving shaft are provided with intermittent linkage type transmission systems, and the tail end of each of the two turning driving shaft is provided with a hub for outputting a measurement signal. The intermittent linkage type crop harvest yield monitoring device disclosed by the invention is suitable for dynamic continuous measurement of grain yield of a grain combine.
Description
[0001] technical field [0002] The invention belongs to grain yield measuring equipment of a combine harvester, in particular to an intermittent linkage type crop harvesting yield measuring equipment. Background technique [0003] In recent years, the research and application of "precision agriculture" technology has developed rapidly in developed countries, and has promoted the practice and industrialization of a series of agricultural machinery-related electronic information equipment technologies. Combine harvester grain yield distribution information acquisition technology occupies an extremely important position in precision agriculture technology. At present, the common measurement methods of net grain flow at home and abroad are: one is the impact force sensor technology. American Case Company installs a force sensor at the outlet of the grain elevator, and the grain periodically hits the force plate along the guiding device, and the grain flow can be measured th...
