Problems solved by technology

[0003] At present, there are almost no special harvesters for millet in agricultural machinery products, so most areas still use manual harvesting for millet harvesting, or use wheat harvesters to replace parts.
[0004] The efficiency of manual harvesting is extremely low and labor costs are high; farmers use wheat harvesters to harvest millet in many ways, but this method is only based on the platform of the wheat harvester, by replacing the concave plate, roller parts or adjusting the parameters of the parts Harvesting is more efficient than manual harvesting, but because the straw is green and mature, it has high toughness and is not easy to break. The threshing drum of the harvester is not suitable for hitting and rubbing the millet straw, and the straw will block the threshing drum and entrainment. Problems such as high loss rate and high impurity rate

Abstract

The invention discloses a millet threshing roller, and relates to the technical field of agricultural mechanical equipment. The millet threshing roller comprises a rear roller body, a plurality of plate teeth and a plurality of toothed bars; the rear roller body sequentially comprises a threshing section and a crushing section in the direction away from a feeding port; the threshing section and the crushing section are connected; the multiple plate teeth are fixedly arranged on the outer side face of the threshing section at intervals side by side in the circumferential direction of the rear roller body; the multiple toothed bars are evenly distributed on the outer side face of the crushing section; and the multiple toothed bars and the surface making contact with the outer side face of the rear roller body are arranged in an angle mode. The invention further discloses a millet combine harvester. The millet combine harvester comprises the millet threshing roller, a top cover located above the threshing roller and a grating concave plate located below the threshing roller, so that the entrainment loss rate and the impurity rate of millet and the blocking frequency of straw to the threshing roller can be reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a millet threshing drum and a millet combine harvester. Background technique [0002] Millet is a small crop with green and mature stalks, low-hanging ears, small and light grains. In recent years, with the promotion of domestic high-quality hybrid millet and the sharp increase in market demand for miscellaneous grains, millet production has begun to be valued and expanded. Farmers' production income and planting enthusiasm have also been greatly improved. However, the biggest "bottleneck" affecting millet production is harvesting. [0003] At present, there are almost no special harvesters for millet in agricultural machinery products, so most areas still use manual harvesting for millet harvesting, or use wheat harvesters to replace parts. [0004] The efficiency of manual harvesting is extremely low and labor costs are high; farmers use wheat harv...
