specific Embodiment approach 1

[0007] Specific implementation mode one: combine Figure 1 ~ Figure 3 Describe this embodiment, this embodiment includes front support semi-shaft 1, main shaft 2, screw blade 3, conical cylinder 4, fixed plate 5, closed cylinder 6, rear support semi-shaft 7, two sealing devices 8, a plurality of teeth Rod fixing plate 9, a plurality of arc gear rods 10, a plurality of plate tooth seats 11, a plurality of trapezoidal plate teeth 13 and a plurality of finger-shaped nail teeth 12, the rear end of the front support half shaft 1 is connected to the main shaft 2 through the connecting element The front end is connected, and the front end of the rear support half shaft 7 is connected to the rear end of the main shaft 2 through a connecting element. This design is convenient for disassembly and maintenance, which can reduce the maintenance cost of the user. The outer surface of each arc gear bar 10 is arc-shaped, A plurality of arc-shaped racks 10 are evenly distributed along the same...

specific Embodiment approach 2

[0008] Specific implementation mode two: combination figure 1 This embodiment will be described. In this embodiment, viewed from the front end of the main shaft 2 to the rear end, the direction of rotation of the plurality of arc-shaped gear bars 10 is opposite to the direction of rotation of the threshing cylinder. This design can reduce the resistance when the drum works. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

specific Embodiment approach 3

[0009] Specific implementation mode three: combination figure 1 To describe this embodiment, the included angle α between each arc rack 10 of this embodiment and the center line N-N of the rack cylinder is 3°-6°. This design can effectively increase the speed of the crop moving backwards and reduce the resistance of the drum when it is working. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a semi-open axial flow threshing cylinder and relates to a threshing cylinder for a combined harvester in order to solve the problems that the linear speed of the front end of the threshing cylinder is low and grains are easy to paste and lose because the threshing cylinder on the combined harvester is an open conical cylinder. A plurality of arc toothed bars are uniformly distributed along the same circumference so as to form an equaldiameter toothed bar drum; each arc toothed bar is slantways arranged relative to the central line of the toothed bar drum; the inclination directions of the plurality of arc toothed bars are consistent; one end of each arc toothed bar is connected with a closed barrel and the other end of the arc toothed bar is connected with a fixed disk; a plurality of toothed bar fixing disks are arranged in parallel between the fixed disk and the closed barrel; the threshing cylinder is fixedly arranged on a main shaft; the closed barrel is positioned on one side of a rear supporting semiaxis; a plurality of finger-shaped nail teeth are arranged on the outer surface of each arc toothed bar along the length direction at equal intervals; a plurality of plate tooth seats are arranged on an extended line, positioned on the central line of each arc toothed bar, of the outer surface of the closed barrel; and a trapezoid plate tooth is arranged on each plate tooth seat. The semi-open axial flow threshing cylinder is used for the combined harvester.

Description

technical field [0001] The invention relates to a threshing drum used on a combine harvester. Background technique [0002] The threshing drum on the existing combine harvester is an open conical drum, and the circumference formed by the outer surface of the nail teeth on the conical drum is conical. , affecting the threshing effect. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the threshing drum on the existing combine harvester is an open conical drum. When working, the front end line speed of the threshing drum is low, and the threshing drum is easy to wrap and run away grain, which affects the threshing effect. A semi-open axial flow threshing drum. [0004] The invention includes a front support half shaft, a main shaft, a spiral blade, a conical cylinder, a fixed plate, a closed cylinder, a rear support half shaft, two sealing devices, a plurality of gear rod fixed discs, a plurality of arc-shaped gear rods, a...
