Abstract

The invention discloses a closed threshing cylinder of a millet harvester, which comprises a shaft tube, a cylinder, a conical cylinder, feeding blades and threshing blocks, wherein the shaft tube isarranged in the cylinder and the conical cylinder in a penetrating manner, one end of the cylinder is connected with the large end of the conical cylinder, the feeding blades are arranged on the conical cylinder, and multiple threshing blocks are uniformly distributed on the outer surface of the cylinder. The single longitudinal axial flow type closed threshing cylinder special for millet is simple and practical in structure, the threshing and separating capacity can be improved when the millet threshing cylinder works, and meanwhile the problems of insufficient threshing, more millet codes and the like during harvesting work can be solved.

Description

technical field [0001] The invention relates to the technical field of a threshing cylinder, in particular to a closed type threshing cylinder of a millet harvester. 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. [0003] Millet is a small crop with green and mature stalks, drooping ears, small grains and light grains. It is difficult to separate the grains from the stalks during harvesting, the grains are not easy to remove, the loss rate of entrainment and cleaning is high, and the damage is serious. [0004] At present, there are three types of millet threshing drums that have been used in the market. The first is a ...
