Abstract

The invention relates to a variable-diameter threshing cylinder, and belongs to agricultural machinery. A left starframe and a right starframe are fixedly mounted on a cylinder main shaft; a left supporting rod and a right supporting rod are inserted on the left starframe and the right starframe; a sliding column A and a sliding column B are fixedly mounted on the left supporting rod and the rightsupporting rod; a peg saddling with threshing pegs is mounted on the left supporting rod and the right supporting rod in a supporting manner; a left regulating gear and a right regulating gear are rotatably mounted on the cylinder main shaft in a sleeving manner; an arc-shaped groove A and an arc-shaped groove B are formed in the left regulating gear and the right regulating gear; the sliding column A is inserted in the arc-shaped groove A, and the sliding column B is inserted in the arc-shaped groove B; a left saddling and a right saddling are fixedly mounted on the left starframe and the right starframe; an adjusting transmission shaft is mounted on the left saddling and the right saddling; a left driving gear and a right driving gear are fixedly mounted on the adjusting transmission shaft; a polygonal adjusting cap is fixedly mounted at the end head of the adjusting transmission shaft; and a belt pulley is fixedly mounted on the cylinder main shaft. The variable-diameter threshingcylinder disclosed by the invention is simple, novel and reasonable in structure, low in manufacturing cost, simple and easy and convenient in adjusting operation, high in adaptability, and good in threshing effect.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a variable-diameter threshing cylinder on a threshing machine tool. Background technique [0002] The traditional crop grain threshing cylinders, including the bar-shaped threshing cylinder, the spike-toothed threshing cylinder, and the bow-toothed threshing cylinder, cannot realize the adjustment and change of the diameter of the cylinder, that is, the diameter of the cylinder is fixed. When used in actual threshing operations, since the diameter of the threshing cylinder cannot be changed, the threshing operation distance between the threshing cylinder and the threshing concave plate that cooperates with the operation is fixed. At the same time, it affects the quality of threshing, including multiple operating indicators such as cleaning rate, grain breaking rate, and grain recovery rate. When the crop yield is low or the feeding amount is low, the operating efficiency of the thr...
