Combine

Abstract

The invention provides a combine which can allow a grain storage device equipped with a conveying cylinder rotating up and down around an axis in a front and back direction of a machine body to rotate in a direction outside the machine body without interference with the conveying cylinder, thus improving maintainance efficiency. A conveying screw (8) is disposed between a front wall (1f) and a back wall (28) of the grain storage device (1); a front side part of a first cylinder part (2) is fixed at the lower part of the back wall (28) of the grain storage device (1); the back side part of the first cylinder part (2) is axially connected with a front side part of a second cylinder part (4) fixed at a side of a machine body frame (3) through a first vertical shaft (5) with a same axis as a second axis (Z) in a free engagement and separation manner; the back side part of the second cylinder part (4) is engaged with a front side part of a third cylinder part (7) disposed at a base part of a conveying cylinder (6) in a manner of free relative rotation around an axis of the conveying screw (8) coaxial with a first axis (Y).

Description

technical field [0001] The present invention relates to combine harvesters. Background technique [0002] Conventionally, a combine has been equipped with a grain storage device in order to store the grains threshed and sorted by the threshing device. [0003] In addition, in order to discharge the grains accumulated in the grain storage device during the harvesting and threshing operation to the loading platform of the truck, etc., a screw conveyor type grain discharge unit is provided at the rear side of the grain storage device. device. [0004] As the grain discharging device, Patent Document 1 discloses a technique in which a conveying cylinder is vertically provided on the rear side of a grain accumulating device mounted on a body frame, and the conveying cylinder can be used in conjunction with the grain storage device. The shaft center of the conveying screw arranged at the bottom of the grain storage device is centered on the coaxial shaft center, and freely undul...

AI Technical Summary

Problems solved by technology

[0007] However, in the technique described in the above-mentioned Patent Document 1, there is a disadvantage that the grain accumulating device cannot be rotated to the outside of the machine body, and the part inside the body of the threshing device hidden by the grain accumulating device cannot be easily detected. waiting for maintenance

[0008] Moreover, even if the grain storage device can be rotated toward the outside of the body, the axis of the vertical direction supporting the grain storage device is arranged at a position closer to the inside of the body than the axis of the body supporting the transport cylinder in the front and rear direction. In this case, there is also the following problem: when the grain storage device is rotated to the outside of the body, the rear part of the grain storage device is likely to interfere with the rear conveying cylinder, so that the amount of rotation to the outside of the body Restricted, the working space is narrowed and the efficiency of maintenance is low
