combine harvester

Abstract

PURPOSE: A combine is provided to rotate a grain storage unit including a return container repetitively rotating up-and-down in the circumference of the axis in a front and a rear of a body without interfering with a return container. CONSTITUTION: A combine includes a threshing apparatus(18) installed in one side of left and right sides of a body frame including a traveling apparatus(20); a grain storage unit(1) and a grain discharge return container(6) installed in the left and right sides of a body frame; a maintenance unit installing the return container to be repetitively rotating up-and-down in a first axial circumference in the front and the rear directions of the body to support; a return screw formed between a front wall and a rear wall of the grain storage unit while opening a check unit in a upper wall of the grain storage unit; and a first container member front side unit fixed to the lower part of the rear wall of the storage unit.

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
