Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0023] Such as figure 1 and figure 2 As shown, the threshing cylinder with adjustable threshing gap in this embodiment includes a main shaft 1 and several racks 2 with threshing teeth 21, and each rack 2 can be adjusted in the radial direction of the main shaft 1 with the main shaft 2 through a clearance adjustment mechanism 3. 1 are installed on the main shaft 1 in the manner of spacing between them, several gear rods 2 are arranged at intervals around the axis of the main shaft 1, and the sliding sleeve 4 is installed on the main shaft 1 to slide along the axial direction of the main shaft 1, and each gap adjustment mechanism 3 is connected with the sliding sleeve 4 It is connected with the adjustment mechanism that adjusts the distance between the gear rod 2 and the main shaft 1 by reciprocating sliding with the sliding sleeve 4,...

The invention discloses a threshing cylinder capable of regulating threshing intervals. The threshing cylinder comprises a main shaft and a plurality of toothed bars with threshing teeth, wherein thetoothed bars are mounted on the shaft through interval regulating mechanisms in a manner that the intervals between the toothed bars and the main shaft can be regulated along the radial direction of the main shaft; the toothed bars are distributed at intervals around the axis of the main shaft; sliding sleeves which are slidably arranged along the axial direction of the main shaft are mounted on the main shaft; the interval regulating mechanisms are regulating mechanisms which are connected with the sliding sleeves and can slide back and forth along the sliding sleeves so as to regulate the intervals between the toothed bars and the main shaft; and the threshing cylinder further comprises a sliding driving assembly for driving the sliding sleeve to slide back and forth. By regulating the radial relative positions between the toothed bars and the main shaft, the toothed bars can cooperate with a concave grid to regulate the threshing intervals of the threshing cylinder. The threshing cylinder has the advantages of simple and compact structure, high working stability and reliability, easiness in production and assembling, good regulation synchronism and the like.
Description
technical field [0001] The invention relates to the technical field of agricultural machinery, 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 exp...
