Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a harvester.

[Conventional technology]

Conventionally, in a harvester, an operator manually swings the paddy bag so that the grain bagging of the paddy bag is improved by directly handling the paddy bag by hand.

[Problems to be solved by the invention]

In the conventional harvester, when trying to supply grain culms to the threshing section and give shaking to the paddy bag alone, reciprocating movement between the working section and the bagging section for feeding the grain threshing section to the threshing section Not only does it have to walk for this reciprocating movement, but the one that does not have a device for automatically feeding the grain culms into the feed chain from the feed table must be shaken for the paddy bag. During that time, it was necessary to interrupt the grain supply, resulting in poor work efficiency.

An object of the present invention is to provide a harvester that can easily and efficiently perform work while improving grain clogging in a paddy bag even when working alone.

[Means for Solving Problems] A characteristic feature of the harvester according to the present invention is that a bag supporting device including a bag receiving rod for hanging a paddy bag and a bag receiving stand for supporting the bottom surface of the paddy bag is provided. A manual operation tool for swingably mounting the seesaw around the swing axis provided on the machine body and swinging the bag support device around the swing axis is provided, and the manual operation tool is fixed on the machine body side. It is configured such that it can be engaged with and disengaged from, and this manual operation tool is arranged in a working section for artificially supplying grain culms to the threshing section, and its operation and effect are as follows.

[Action]

It is possible to operate the operation tool while operating the operation unit for supplying grain culms to the threshing unit to operate the paddy bag swaying mechanism, and to impart swaying to the paddy bag during grain supply.

Further, since the seesaw can be rocked by supporting the middle portion of the bag supporting device, the center of gravity of the bag supporting device is provided on both sides of the rocking shaft as compared with the structure in which one end side of the bag supporting device is supported. The bag supporting device can be rocked by a relatively light operating force only by moving the bag supporting device.

Further, the swinging of the bag supporting device can be restricted by using the manual operation tool.

[Effect of device]

Since the operation of shaking the paddy bag can be done from the work section for supplying the grain culms, the threshing work while the amount of grains packed in the paddy bag is maximized even if one person works alone It became easy to do without the need for a round-trip walk between them, and at the same time, it became possible to work efficiently by supplying grain culms and shaking the bags at the same time.

Moreover, since the paddy bag rocking mechanism supports the intermediate portion of the bag supporting device and can rock the seesaw, there is an advantage that the rocking operation can be performed with a light operating force. Further, the manual operation tool also serves as a swing control of the bag supporting device, and the overall configuration is simple.
