DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a harvester such as a combine harvester, and more particularly to a harvester having a hopper for temporarily storing grains threshed by a threshing apparatus.

[0002]

2. Description of the Related Art In harvesters such as combine harvesters and harvesters, for example, a threshing device is provided on one side in the width direction of a machine body supported by a crawler traveling device, and threshing is performed on the other side by the threshing device. A hopper is provided for lifting and transferring the crushed grains through a crushing cylinder containing a helical shaft therein, and temporarily storing the grains. At the lower part of the hopper, a gutter for guiding grain is hung, and a shutter for opening and closing a grain discharge passage is built in the gutter.

To take out the grains in the hopper to the outside, a paddy bag is hung below the hopper, and the grains in the hopper are discharged into the paddy bag through the gutter, and packed in a bag. I am trying to do it.

[0004] As a type of the above-mentioned gutter, for example,
As described in Japanese Patent Application Laid-Open No. 2-13142, a slide shutter that moves in a direction substantially perpendicular to the grain discharge path to open and close the discharge path,
As described in JP-A-63-63, there is known a rotary shutter that opens and closes a discharge path by rotating about a rotation axis together with the rotation axis.

[0005]

In the above-mentioned conventional example, the shape of the base at the lower part of the hopper is different between the gutter having the slide shutter and the gutter having the rotary shutter. In order to change from a gutter to a rotary gutter, the gutter alone could not be replaced, and the entire hopper had to be replaced.

For this reason, hoppers having two types of specifications corresponding to the types of gutters are manufactured, the number of parts is increased, and management in assembly is not easy. There has been a demand for a technique capable of mounting both a slide type shutter and a rotary type shutter simply by replacing only the gutter.

On the other hand, for example, in a gutter with a built-in slide shutter, the upper end of the gutter case is fastened to the lower part of the hopper with a bolt and a nut, but the nut is fixed with the nut being exposed to the outside. Therefore, when the operator sets the paddy bag, the nut may come into contact with the hand of the operator.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem, and an object of the present invention is to provide a gutter having a slide shutter incorporated in one kind of hopper and a gutter having a rotary shutter incorporated therein. It is an object of the present invention to provide a harvester to which a gutter can be attached.
