Description
本考案は、ロータリ作業機のカバー装置に関する。詳細には、耕耘爪により掻き上げられた土の左右側方への飛散位置を調節するためのサイドカバーのロータリカバーへの連結部材を改良したロータリ作業機のカバー装置に関する。 The present invention relates to a cover device for a rotary working machine. More specifically, the present invention relates to a cover device for a rotary working machine in which a member for connecting a side cover to a rotary cover for adjusting the scattering position of soil lifted by a tilling nail to the left and right sides is improved.
耕耘爪の上方を覆うロータリカバーの左右側方にサイドカバーを連結して、前後方向を軸としてロータリカバーに対して回動自在に構成し、耕耘爪によって掻き上げた土をロータリカバーによって案内させて、サイドカバーによって土の飛散位置を調節させるロータリ作業機はすでに存在している（特許文献１）。 A side cover is connected to the left and right sides of the rotary cover that covers the upper part of the tilling claw, and is configured to be rotatable with respect to the rotary cover about the front-rear direction. Therefore, there is already a rotary working machine that adjusts the scattering position of soil by a side cover (Patent Document 1).
従来のロータリ作業機では、耕耘爪上方のロータリカバーの上面側縁部に形成したボス部にＬ字型に形成した連結部材の軸部を遊嵌固定し、連結杆部をサイドカバーと取付金具とで挟んでボルト等で固定して、ロータリカバーに対しサイドカバーを回動可能かつ接近摺動可能に構成していた。しかし、上記のような構成ではサイドカバーを回動するとロータリカバーとサイドカバーとの間の隙間の幅が変化するため、サイドカバーを接近摺動して隙間を調整していたが、手間がかかるし、また部品点数も多くなってしまっていた。
解決しようとする問題点は、ロータリカバーに対してサイドカバーを回動させた際に隙間が生じてしまい、隙間をなくすための調整に手間がかかっていた点であり、本考案は少ない種類の部品点数で隙間を生じさせることなく、また手間を要せずにサイドカバーを回動して任意の位置で固定可能とすることを目的としてなされたものである。 The problem to be solved is that a gap is generated when the side cover is rotated with respect to the rotary cover, and it takes time to adjust the gap to eliminate the gap. The object of the present invention is to enable the side cover to be rotated and fixed at an arbitrary position without causing a gap in the number of parts and without any trouble.

A notch is provided at one side edge of a substantially rectangular metal plate, and convex portions and concave portions each having an equal interval are alternately formed and arranged symmetrically, and the convex portion is folded into a semi-cylindrical shape. The connecting members are attached to the side edges of the rotary cover and the side cover so as to adjust the tightening force, and the nails protrude from the side edges of the respective covers. The rods were staggered to clamp the shaft rod.
請求項２記載のごとく、前記軸芯棒は、前記取付金具によって前記ロータリカバーおよび前記サイドカバーの端縁部に臨む位置に配置した。 As described in claim 2, the shaft rod is arranged at a position facing the edge of the rotary cover and the side cover by the mounting bracket.
請求項３記載のごとく、前記取付部材を取付けるロータリカバーとサイドカバーの側縁部を、軸芯棒の長さや径に合わせて切欠いた。 According to a third aspect of the present invention, the side edges of the rotary cover and the side cover on which the mounting member is mounted are notched according to the length and diameter of the shaft rod.
請求項１記載のごとく連結部材を構成することにより、同型の取付金具を４枚用意すれば、サイドカバーを回動自在に構成できるとともに任意の位置で固定することができ、金型が一つで済むためコストの低減を図ることができる。 By configuring the connecting member as described in claim 1, if four mounting brackets of the same type are prepared, the side cover can be configured to be freely rotatable and can be fixed at an arbitrary position. Therefore, cost can be reduced.
請求項２記載のごとく軸芯棒を配置したことにより、回動中心がロータリカバーおよびサイドカバーの端縁近傍に位置するため、サイドカバーの回動によってロータリカバーとサイドカバーとの間に大きく隙間が生じることがない。 Since the rotation center is located near the edges of the rotary cover and the side cover by arranging the shaft core as described in claim 2, a large gap is formed between the rotary cover and the side cover by the rotation of the side cover. Does not occur.
請求項３記載のごとく、連結部を取付けるロータリカバーとサイドカバーの側縁部を切欠いたことにより、ロータリカバーとサイドカバーの間に生じる隙間をより狭くすることができる。 According to the third aspect of the present invention, the gap formed between the rotary cover and the side cover can be further reduced by notching the side edges of the rotary cover and the side cover to which the connecting portion is attached.
