(イ) 産業上の利用分野
本考案は殻稈を刈取脱穀するコンバインのコン
バインカツタにおける切藁排出装置に関する。[Detailed description of the invention] (a) Field of industrial application The present invention relates to a cut straw discharge device in a combine cutter for a combine harvester that harvests and threshes husks.

られている。(b) Prior art Conventionally, cut straw was transferred to the upper part of the suction fan discharge cylinder using a spiral auger, and the cut straw was dropped from above the discharge cylinder, and the cut straw was released and spread in the field by the wind pressure of the suction fan. What you did is already known.

う欠点があつた。(c) Problems to be solved by the invention The cut straw discharging device of the known combine harvester cutter discharges the cut straw transferred by the ocher into the field by the wind pressure of the suction fan at the end of the transfer. The disadvantage was that the discharge direction was not fixed and the cut straw could not be uniformly spread. In addition, since the cut straw is dropped immediately behind the suction fan discharge tube, the exhaust air of the suction fan is suppressed, which reduces the suction force of the suction fan and deteriorates the air selection performance.

た。(d) Means for Solving the Problems The present invention includes an auger for horizontally transporting cut straw below the cutting blade of a cutter, storing the auger in a casing, and installing a jump plate at the end of the transport of the auger. At the same time, a discharge port is provided, and the discharge tube of the suction fan is brought close to the rotation locus of the ejection plate at the bottom of the discharge port and extended rearward, thereby configuring the upper surface of the discharge tube as a straw-throwing guide plate. By using the upper surface of the suction fan discharge cylinder as a guide, the discharge direction of the cut straw is made to be in a substantially constant direction toward the rear, and the discharge wind is also used to scatter the cut straw while suppressing a decrease in the wind pressure of the suction fan. Solved the problem mentioned above.

がら圃場に散布する。(e) Operation The cut straw shredded by the cutting blade is transported to the discharge port by the auger. Then, the cut straw is discharged by the scraping action caused by the rotation of the spring plate provided at the end of the transfer and the exhaust air of the suction fan, and at this time, the discharge cylinder of the suction fan approaches the rotation locus of the spring plate. The cut straw is thrown in a fixed direction of release toward the rear, and is dispersed onto the field while being assisted by the discharge air from the suction fan.

Reference numeral 1 denotes a threshing device mounted on a machine base having a traveling device, in front of which a pre-processing device consisting of a reaping section, a conveying section, etc. is installed, and a desk-shaped cutter 2 is attached to the rear. The stalks of straw discharged from the discharge culm are sent later by the straw discharge chain 3 and the clamping rails, and when the stalks are discharged as they are without being shredded, the switching plate 4 is closed using the handle. The rail 5 on the top surface of the switching plate 4 faces the straw removal chain 3,
The waste straw passes over the cutter 2 and is discharged backward.
また、排藁を細断処理する場合は切換板４を開
くと排藁がカツタ２に供給される。 Further, when the waste straw is to be shredded, the waste straw is supplied to the cutter 2 when the switching plate 4 is opened.

A horizontal shaft 10 of approximately equal length is supported, and an auger 12 housed in a substantially U-shaped casing 11 is attached to the base side of the horizontal shaft 10, and is driven in the same direction by a shaft 9. .

１５の上面１５ａが位置し、跳出板１４の回転軌
跡と該吐出筒１５の上面１５ａは放出方向を定め
るように接近させてある。 The cut straw that has been shredded by the cutting blades 7 and so on and falls onto the auger 12 is transferred by the auger 12 to the mown field side by the rotation of the horizontal shaft 10. A discharge port 13 is formed from the transfer end of the auger 12 to the tip side, and a jump plate 14 is protruded from a portion of the horizontal shaft 10 facing the discharge port 13. The upper surface 15a of the discharge cylinder 15 of the suction fan is located below, and the rotation locus of the spring plate 14 and the upper surface 15a of the discharge cylinder 15 are brought close to each other so as to determine the discharge direction.

１４の回転軌跡は吐出筒１５の上面１５ａと接近
するように設けられているため、切藁を漏れなく
掻き出すと共にその放出方向を一定にすることが
できる。 Therefore, the cut straw transferred to the discharge port 13 is first splashed out by the rotation of the spring plate 14, and at this time, since the rotation locus of the spring plate 14 is provided so as to approach the upper surface 15a of the discharge tube 15, the cut straw is It is possible to scrape out the straw without leaking and to make the direction of the discharge constant.
更に跳ね出された切藁は跳出板１４の投擲方向
に略沿つて吐出されて吸引フアンの風圧により均
等に圃場に分散させることができる。 Furthermore, the thrown straw is discharged substantially along the throwing direction of the jumping board 14, and can be evenly dispersed in the field by the wind pressure of the suction fan.
このように、細断された切藁わらは跳出板１４
の作用と吸引フアンの吐出風により良好な状態で
放出分散される。 In this way, the shredded cut straw is transferred to the jumping board 14.
It is released and dispersed in good condition due to the action of the pump and the discharge air of the suction fan.
また吸引フアンの風は従来のもののように略垂
直に落下する切藁を後方へ方向変換して放擲せず

目的である風選作用を低下させることがない。(g) Effects of the invention The present invention includes an auger 12 for horizontally transferring cut straw below the cutting blade 7 of the cutter 2, and
2 is housed in the casing 11, and the auger 12
A jump plate 14 is attached to the transfer terminal end and a discharge port 13 is provided at the bottom of the discharge port 13.
By bringing the discharge tube 15 of the suction fan close to the rotation locus of the suction fan and extending it backward, the upper surface 15a of the discharge tube 15 is configured as a cut straw throwing guide plate. When the spring plate 14 springs out, the upper surface of the discharge tube 15 guides and guides the thrown straw in the same direction as the exhaust air blown out from the discharge tube 15, and throws it onto the upper surface of the exhaust air flow. The throwing force of the jumping board 14 can be fully exerted, the direction of throwing the cut straw coincides with the direction of discharging the exhaust air, and the cut straw is thrown onto the exhaust flow without obstructing the exhaust flow, and the suction fan It does not reduce the wind selection effect, which is the original purpose.
また、切藁の投擲方向と吸引フアンの排風方向
が同一で吐出筒１５の上面１５ａから投擲される
ので投擲効率及び分散効率を一層向上することが
できる。 Further, since the throwing direction of cut straw and the blowing direction of the suction fan are the same and the cutting straw is thrown from the upper surface 15a of the discharge cylinder 15, the throwing efficiency and dispersion efficiency can be further improved.
更に、跳出板１４の案内板を別個に設けず吸引
フアン吐出筒１５により兼用させているため構造
を単純化することができると共にコストの低減を
図ることができる。 Further, since the guide plate for the ejecting plate 14 is not provided separately and is also used by the suction fan discharge cylinder 15, the structure can be simplified and costs can be reduced.
