Description

収穫機harvester
　本発明は、収穫機に関する。 The present invention relates to a harvester.
　従来、収穫機として、例えば、特許文献１に記載の収穫機が知られている。特許文献１に記載の収穫機には、植立穀稈を掻き込む掻込リール（文献では「掻き込みリール〔１０〕」）が備えられている。掻込リールには、機体左右方向に沿って延びる回転軸心（文献では「リール軸芯〔Ｐ〕」）周りで回転可能な回転軸（文献では「リール軸〔１５〕」）と、回転軸に支持され、回転軸心周りで回転軸と一体回転可能な左右のリールフレーム（文献では「側板〔１４〕」）と、左側のリールフレームの外周部と右側のリールフレームの外周部とに亘って回転軸心周りに間隔をあけて設けられる複数のタイン支持部材（文献では「タイン支持バー〔１７〕」）と、複数のタイン支持部材の夫々に回転軸心方向に間隔をあけて設けられ、植立穀稈に掻き込み作用する複数のタイン（文献では「タイン〔１８〕」）と、が備えられている。リールフレームには、その中央部から放射状に延びる複数のアーム部（文献では「アーム部〔１４２〕」）が備えられている。 Conventionally, as a harvester, for example, the harvester described in Patent Document 1 is known. The harvester described in Patent Document 1 is equipped with a rake reel (“rake reel [10]” in the document) for raking planted grain culms. The scraping reel has a rotating shaft (“reel shaft [15]” in the literature) rotatable around a rotating shaft (“reel shaft [P]” in the literature) extending along the left-right direction of the machine body, and a rotating shaft and the left and right reel frames ("side plate [14]" in the document) that can rotate integrally with the rotation axis around the rotation axis, and the outer periphery of the left reel frame and the outer periphery of the right reel frame. a plurality of tine support members ("Tine Support Bar [17]" in the document) spaced apart around the rotation axis, and a plurality of tine support members spaced apart in the direction of the rotation axis. , and a plurality of tines (“Tine [18]” in the literature) that act to scrape the planted grain culms. The reel frame is provided with a plurality of arm portions (“arm portion [142]” in the literature) radially extending from the central portion thereof.
日本国特開２０１７－１１２９７７号公報（JP2017-112977A）Japanese Patent Application Laid-Open No. 2017-112977 (JP2017-112977A)
　特許文献１に記載の収穫機では、リールフレームの外周部（文献では「アーム部〔１４２〕の先端部〔１４２ａ〕」）が角張っている。このため、掻込リールが植立穀稈を掻き込む際に、リールフレームの外周部に植立穀稈が引っ掛かり易い。 In the harvester described in Patent Document 1, the outer peripheral portion of the reel frame (in the document, "the tip [142a] of the arm [142]") is angular. Therefore, when the rake reel rakes the planted culms, the planted culms are likely to be caught on the outer peripheral portion of the reel frame.
　上記状況に鑑み、掻込リールが植立穀稈を掻き込む際に、リールフレームの外周部に植立穀稈が引っ掛かり難い収穫機が要望されている。 In view of the above situation, there is a demand for a harvester in which the planted culms are less likely to get caught on the outer periphery of the reel frame when the rake reels rake in the planted culms.
　本発明の特徴は、植立穀稈を掻き込む掻込リールを備えている収穫機であって、前記掻込リールは、機体左右方向に沿って延びる回転軸心周りで回転可能な回転軸と、前記回転軸に支持され、前記回転軸心周りで前記回転軸と一体回転可能な左右のリールフレームと、左側の前記リールフレームの外周部と右側の前記リールフレームの外周部とに亘って前記回転軸心周りに間隔をあけて設けられる複数のタイン支持部材と、前記複数のタイン支持部材の夫々に前記回転軸心方向に間隔をあけて設けられ、植立穀稈に掻き込み作用する複数のタインと、を有し、前記リールフレームの外周形状は、円形状に形成されていることにある。 A feature of the present invention is a harvester provided with a raking reel for raking planted grain culms, wherein the raking reel has a rotating shaft that can rotate around a rotating shaft center that extends along the left-right direction of the machine body. , the left and right reel frames supported by the rotating shaft and integrally rotatable with the rotating shaft around the center of rotation, and the outer peripheral portion of the left reel frame and the outer peripheral portion of the right reel frame. a plurality of tine support members provided at intervals around the axis of rotation; and a plurality of tine support members provided at intervals in the direction of the axis of rotation and acting to rake planted grain culms. tines, and the outer peripheral shape of the reel frame is formed in a circular shape.
　本特徴構成によれば、リールフレームの外周形状が円形状に形成されているため、リールフレームの外周部が角張っていない。これにより、掻込リールが植立穀稈を掻き込む際に、リールフレームの外周部に植立穀稈が引っ掛かり難い。 According to this characteristic configuration, since the outer peripheral shape of the reel frame is formed in a circular shape, the outer peripheral portion of the reel frame is not angular. As a result, when the raking reel rakes in the planted culms, the planted culms are less likely to get caught on the outer peripheral portion of the reel frame.
　また、リールフレームの外周形状が円形状に形成されていることにより、タイン支持部材の横端部を支持する支持部材を、リールフレームの外周部における任意の箇所に設けることができる。これにより、タイン支持部材の数が異なる複数の掻込リールにおいて、リールフレームを兼用することができる。 In addition, since the outer circumference of the reel frame is circular, the support member for supporting the lateral end of the tine support member can be provided at any position on the outer circumference of the reel frame. Thus, the reel frame can be used in common for a plurality of pick-up reels having different numbers of tine support members.
　さらに、本発明において、前記リールフレームは、円板形状の部材によって構成されていると好適である。 Furthermore, in the present invention, it is preferable that the reel frame is configured by a disk-shaped member.
　本特徴構成によれば、円板形状の部材という薄型の部材によって、リールフレームの軽量化を図ることができる。 According to this characteristic configuration, it is possible to reduce the weight of the reel frame by using a thin member that is a disk-shaped member.
　さらに、本発明において、前記リールフレームの外周部に、前記リールフレームの外周部の全周に亘る環状であって前記回転軸心方向に向けて曲がる曲げ部が形成されていると好適である。 Furthermore, in the present invention, it is preferable that the outer peripheral portion of the reel frame is formed with an annular bent portion that extends along the entire circumference of the outer peripheral portion of the reel frame and that is bent toward the rotation axis direction.
　本特徴構成によれば、曲げ部がリブ作用を果たすことになる。これにより、リールフレームの強度を向上させることができる。 According to this characteristic configuration, the bent portion functions as a rib. Thereby, the strength of the reel frame can be improved.
　さらに、本発明において、前記リールフレームの外周部における前記複数のタイン支持部材に対応する箇所の夫々に、前記タイン支持部材の横端部を支持する支持部材が設けられ、前記支持部材は、前記曲げ部に支持されていると好適である。 Further, in the present invention, support members for supporting the lateral ends of the tine support members are provided at locations corresponding to the plurality of tine support members on the outer peripheral portion of the reel frame, and the support members It is preferably supported on the bend.
　本特徴構成によれば、タイン支持部材の横端部が支持部材を介して曲げ部に支持されることになる。これにより、タイン支持部材を曲げ部によってしっかりと支持することができる。 According to this characteristic configuration, the lateral end of the tine support member is supported by the bent portion via the support member. Thereby, the tine support member can be firmly supported by the bent portion.
　さらに、本発明において、前記リールフレームは、前記リールフレームの外周部から前記リールフレームの中心部に近付くに連れて前記回転軸心方向の一方側に位置するように凹む形状に形成されていると好適である。 Further, in the present invention, the reel frame is formed in a concave shape so as to be positioned on one side in the rotation axis direction as it approaches the center of the reel frame from the outer peripheral portion of the reel frame. preferred.
　本特徴構成によれば、リールフレームが回転軸心方向の一方側に全体的に凹む形状によって、リールフレームの強度を向上させることができる。 According to this characteristic configuration, the strength of the reel frame can be improved by the shape of the reel frame that is entirely recessed on one side in the direction of the rotation axis.
　さらに、本発明において、前記リールフレームは、前記リールフレームの外周部から前記リールフレームの中心部に近付くに連れて前記回転軸心方向で前記掻込リールの左右中心側に位置するように凹む形状に形成されていると好適である。 Further, in the present invention, the reel frame has a shape that is recessed so as to be located on the left-right center side of the scraping reel in the direction of the rotation axis as it approaches the center of the reel frame from the outer peripheral portion of the reel frame. is preferably formed in
　本特徴構成によれば、リールフレームが回転軸心方向で横外側に膨らむ形状に形成されていないことになる。これにより、リールフレームが回転軸心方向の一方側に全体的に凹む形状であっても、掻込リールが回転軸心方向に大型化しないようにすることができる。 According to this characteristic configuration, the reel frame is not formed in a shape that expands laterally outward in the direction of the rotation axis. As a result, even if the reel frame has a shape that is entirely recessed on one side in the direction of the rotation axis, it is possible to prevent the scratch reel from increasing in size in the direction of the rotation axis.
　さらに、本発明において、前記リールフレームに、前記回転軸心方向に向けて開口する開口が形成されていると好適である。 Furthermore, in the present invention, it is preferable that the reel frame is formed with an opening that opens toward the rotation axis direction.
　本特徴構成によれば、開口によってリールフレームの軽量化を図ることができる。また、運転者が開口を通して作業状況（例えば、条合わせの状況）を視認することができる。 According to this characteristic configuration, the weight of the reel frame can be reduced by the opening. In addition, the driver can visually recognize the work status (for example, the status of row alignment) through the opening.
