Description

[Detailed explanation of the invention] (Field of industrial application) This invention is based on the idea that the culms, which are discharged as long culms from the threshing section, or the stem culms of cut down grass, etc., are installed in parallel and in opposite directions. The present invention relates to a culm processing device in which cutting is performed using a plurality of cutting blades and a rotary receiving blade, which are respectively attached to a pair of rotating shafts that rotate.

(Prior art) Conventionally, the above-mentioned work with the disc-type cutter has been cutting work by changing the cutting size to long or short (Japanese Patent Application Laid-open No. 134656/1983), or collecting culms without cutting them (Japanese Patent Publication No. 134656/1983). No. 12371), culm work where only part of the culm is cut off and the remaining culm is collected (Jitko Kosho 53-20427
No.) etc.

(Problem that the invention aims to solve) In recent years, in addition to cutting the culms and scattering them on the field, there is also a method of using the culms, in addition to cutting them and scattering them in the field.After drying the culms in the sun and collecting them with a roll baler, It is increasingly being used as feed for livestock.
However, if the culm remains uncut, the drying rate is poor;
Moreover, if it is shredded, the collection rate with a roll baler will be poor.

This invention aims to provide an exhaust culm processing device that can cut the exhaust culm by changing the cutting dimensions into long and short culms as necessary, and can also process and release the exhaust culm in an easy-to-dry manner. be.
