Harvester seed conveying device

Abstract

The invention discloses a harvester seed conveying device which comprises an impurity horizontal auger, a first seed auger, a second seed auger, a seed slide plate, a middle grain guiding body and a seed lifting auger; the impurity horizontal auger is supported on the rear side of a rack, the first seed auger and the second seed auger are horizontally supported on the front side of the rack, the seed slide plate is arranged between the impurity horizontal auger and the first seed auger in an inclined mode, the middle grain guiding body is transversely and fixedly supported on a rack bottom plate between the first seed auger and the second seed auger, a cavity among the end face of one end of the middle grain guiding body, the rack bottom plate and the rack side wall forms a grain channel. The harvester seed conveying device is simple in structure, low in cost and large in seed storage space. When the grain feeding amount is too large and more seeds exist, the seeds fall into the two seed augers, the seeds cannot be piled up, the seed flowing space is large, in this way, the blocking phenomenon of the seed augers can be effectively avoided, and meanwhile the conveying loads of the two seed augers are reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a conveying device in a harvester, in particular to a harvester grain conveying device capable of avoiding blockage, and belongs to the technical field of agricultural machinery. Background technique [0002] At present, when the combine harvester harvests grains, the grains leaked by the vibrating sieve are transported to the bottom of the grain lifting auger through the grain horizontal auger, and finally the grain lifting auger transports the grains to the granary. However, in the actual operation process, if the amount of grain fed is too large and there are many grains, all the grains will fall into the grain horizontal auger. Since the gap between the grain horizontal auger and the bottom plate of the frame is small, the accumulation of a large number of grains will not only increase the The load on the grain level auger will reduce its service life, and it will easily cause the grain level auger to be blocked.
