Technical Field
The invention belongs to the technical field of agricultural mechanical equipment, and particularly relates to a roller system capable of adjusting a threshing gap.
Background
The threshing gap is one of the main working parameters of the threshing device, and the threshing gap influences the threshing performance to a certain extent. The threshing gap is the gap between the threshing teeth top of the threshing cylinder and the concave sieve. When the threshing gap is smaller, the roller seriously impacts materials to crush the straws, the impurity content of the threshed materials is increased, and threshed grains are difficult to separate, so that the entrainment loss is increased. When the threshing gap is too small or the feed amount is increased, the drum may be clogged. Generally, the threshing gap is determined by testing the better threshing gap of the device after the feeding amount is determined. Because the harvested crops have different types and larger difference of suitable threshing gaps, the combine harvester usually adjusts the threshing gaps by replacing the concave plate sieve or adjusting the position of the concave plate sieve by utilizing a pull rod for adapting to threshing of various crops
When the thresher works, the gap between the rollers needs to be adjusted according to the feeding amount of materials so as to meet different working condition requirements, and when the thresher is blocked, the gap between the rollers needs to be adjusted so as to eliminate the phenomenon of blocking caused by the materials.
