Description

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a pulling device that acts on a planted stem culm;
It is equipped with a reaping device that reaps the planted stem culms after being raised, and a binding device for the harvested stem culms, and the binding device includes a pucker that scrapes the harvested stem culms into the binding space, and a pruner that scrapes the harvested stem culms into the binding space, and a combing device that removes the bundled stem culms from the binding space. One arm is provided for forcibly discharging the bundles to the outside, and a collecting section capable of collecting and holding a plurality of tied bundles of stalks is provided on the side of the body on the side of the bundle discharge port of the binding space. This invention relates to a reaping and tying machine that is connected to a reaping and tying machine. This type of reaping and tying machine collects a plurality of stem culm bundles discharged from the binding space of the tying device in a collecting section, and then releases the stem culm bundles in this collecting section all at once into the field. This allows the bundles to be bundled into small bundles that are easiest to handle during subsequent processing such as sun drying and threshing, while the stem and culm bundles released into the field are collected in large units, making subsequent collection work more efficient. Conventionally, when releasing the plurality of stem and culm bundles collected in the collecting section, it is easy to do so.
Separately from the release arm of the binding device, a dedicated release tool was provided. Therefore, a discharge tool dedicated to the plurality of collected stem culm bundles and a drive mechanism for circulating the same within the collection section are required, which makes the entire discharge structure complicated and large, which is disadvantageous in terms of manufacturing and economy. . The present invention aims to make it possible to easily and compactly construct a structure for performing the two types of discharge operations as described above by using one discharge arm that is originally equipped to the binding device. In the above-mentioned device, the one discharge arm is in a first state in which the stem culm bundle in the bundling space is forcibly discharged toward the collecting section; The present invention is characterized in that it is provided with a switching mechanism for switching to a second state in which a plurality of collected stem and culm bundle groups are forcibly released to the outside. That is, in the case of the present invention, it is possible to freely switch between the two types of release states as described above using the one release arm that is originally provided in the binding device, so that the conventional method having the above-mentioned configuration can be used. Compared to the conventional method, a dedicated ejector for forcibly ejecting a plurality of stem culm bundle groups collected in the collecting section to the outside and a drive mechanism for circulating the same within the collecting section are not required, and the ejecting It has now become possible to simplify and compact the structure as a whole.
