Abstract

The invention discloses a threshing drum adjustable in threshing gap. The threshing drum comprises a spindle, a gap adjusting mechanism, a toothed rod and a gap control mechanism. The gap adjusting mechanism and the gap control mechanism are mounted on the spindle, the tail end of the gap adjusting mechanism is connected with the toothed rod, and the gap adjusting mechanism can adjust the toothedrod for radial motion; the gap control mechanism is connected with the gap adjusting mechanism and can control a sliding element of the same for axial sliding, and a spindle driving chain wheel is arranged at one end of the spindle. A threshing drum structure with a spoke and a threshing toothed rod is reformed, the gap adjusting mechanism is used to replace the spoke, and the gap control mechanism is added, so that threshing gap can be adjusted at proper time, the problem of blockage of the threshing drum can be solved effectively, and the threshing drum is wide in application range.

Description

technical field [0001] The invention relates to an agricultural mechanical equipment, in particular to a threshing cylinder with an adjustable threshing gap. Background technique [0002] The threshing gap is one of the main working parameters of the threshing device, and the threshing gap affects the threshing performance to a certain extent. The threshing gap refers to the gap between the threshing tooth top of the threshing drum and the concave plate sieve. If the threshing gap is too small, the drum will hit the material severely, breaking the straw, increasing the residual content of the extruded material, and it is difficult to separate the threshed grains, which will increase the entrainment loss. When the threshing gap is too small or the feeding amount is increased, it may even cause the drum to be blocked. Usually the threshing clearance is after the feeding amount is determined, and the optimal threshing clearance of the device is determined through experiments....
