Millet combined harvester and system thereof

Abstract

The invention discloses a millet combined harvester and a system thereof, and belongs to the technical field of crop combined harvest. The millet combined harvester comprises a header for combined harvest, a threshing separation part and a millet cleaning part. The header comprises a header frame, a reciprocating cutter, a left divider, a right divider, a header screw auger, a reel and a transmission mechanism, and the transmission mechanism is in transmission connection with the reciprocating cutter, the header screw auger and the reel. The threshing separation part comprises a threshing box, a front threshing cylinder, a rear threshing cylinder, a front separating screen, a rear separating screen, a transition separating screen, a front threshing top cover, a rear threshing top cover, and a power mechanism providing power for the front threshing cylinder and the rear threshing cylinder. The millet cleaning part comprises a cleaning frame, a front blower fan, a reciprocating vibration screen, and a vibration mechanism driving the reciprocating vibration screen to vibrate. The millet harvesting system comprises the millet combined harvester mentioned above and a controller. According to the invention, a header ear dropping phenomenon can be effectively controlled, rubbing and beating are integrally carried out, and the loss late, the broken rate and the impurity rate are low.

Description

technical field [0001] The invention relates to the technical field of crop harvesting, in particular to a combine harvester for millet harvesting and a system thereof. Background technique [0002] In recent years, with the promotion of domestic high-quality hybrid millet and the substantial increase in market demand for miscellaneous grains, millet production has begun to be emphasized and expanded, and farmers' production income and planting enthusiasm have also greatly increased. However, the biggest "bottleneck" affecting millet production at present is harvesting. Although several companies have been exploring the combined harvesting of millet machinery in the past two years, they have not been smooth. Mature ears hang down and are highly entangled with each other, and the ears on both sides of the header are seriously twisted; the large ears of millet contain countless spikelets, and it is difficult to thresh the spikelets; the ear bones are easily broken, which incre...

Problems solved by technology

In order to solve this bottleneck, some enterprises are trying to improve the traditional wheat combine harvester and directly use it to harvest millet, but it has not achieved satisfactory results, especially in the case of ear drop, cleaning loss, and impurities. Issues such as the rate are relatively prominent, and cannot be accepted by the majority of farmers
