本考案は、耕耘機に装備するロ−タリ耕耘装置に係るもので、殊に、小型で軽 量な耕耘機に装備して用いるに好適なセンタ−ドライブ形ロ−タリ耕耘装置に関 するものである。 The present invention relates to a rotary cultivator mounted on a cultivator, and more particularly to a center drive type rotary cultivator suitable for being mounted on a small and light cultivator. Is.
【0002】[0002]
周知のように、一般的なロ−タリ耕耘装置は、伝動ケ−ス下部の水平横向き伝 動軸に嵌着する耕耘爪軸筒を進行方向に対して反時計方向に回転させ、それに装 備した耕耘爪のダウンカット回転によって土壌を耕起するように構成されるので あるが、かかる形式のロ−タリ耕耘装置にあっては、耕耘爪の打ち込み荷重が耕 耘機本体の推進を助勢する方向に働くため、殊に、耕耘機が小型軽量である場合 には機体のダッシュ現象が起きて所期の耕耘が行われ難い。 このため、従来においては、板材或いは杆材等の適宜部材で形成した抵抗体を ロ−タリ耕耘装置の後尾部に設け、該抵抗体を土中に喰い込ませることによって 機体のダッシュを阻止することが行われている。 As is well known, a general rotary cultivator rotates a tillage claw shaft tube, which is fitted on a horizontal lateral transmission shaft at the lower part of the transmission case, counterclockwise with respect to the traveling direction and equips it. In this type of rotary cultivator, the driving load of the cultivating claw assists the promotion of the cultivator body. Since it works in the direction, especially when the cultivator is small and lightweight, the dash phenomenon of the airframe occurs and it is difficult to perform desired cultivating. For this reason, in the past, a resistor made of a suitable member such as a plate or rod was provided at the rear end of the rotary cultivator to prevent the dash of the airframe by digging the resistor into the soil. Is being done.
【0003】[0003]
従来のものにおいては、抵抗体に土壌や草藁類などが付着堆積して次第に膨大 化し易く、その状態の抵抗体が土中を進行するために土押し現象が起きて、進行 跡に大きな溝ができ、耕起跡の仕上がりが不整になるという問題点があった。 本考案は、従来のものにおける上記の問題点に鑑みてなされたもので、その目 的とするところは、機体のダッシュを的確に阻止できるものでありながら整斉な 仕上がり状態に耕起することができ、さらに、伝動ケ−ス下の残耕処理も細土効 率よく行えるように改良したロ−タリ耕耘装置を提供することにある。 In the conventional one, soil and grass straw adhere to and accumulate on the resistor, and the resistor is likely to become huge, and the resistor in that state progresses in the soil, causing an urging phenomenon, resulting in a large groove in the track. However, there was a problem that the finish of the plowing trace was irregular. The present invention has been made in view of the above problems in the conventional one, and its purpose is to plunge into a uniform finished state while accurately preventing the dash of the aircraft. Another object of the present invention is to provide an improved rotary cultivator capable of performing the residual tillage treatment under the transmission case with high efficiency of the fine soil.

すなわち、本考案におけるロ−タリ耕耘装置は、水平耕耘爪軸筒(1)を嵌着す る伝動軸(2)に対して所定角度に下傾する傾斜耕耘爪軸筒(3)を伝動ケ−ス(4) に近接配設し、該傾斜耕耘爪軸筒(3)に装備した耕耘爪(5)でもって伝動ケ−ス 下の土壌を耕起するセンタ−ドライブ形ロ−タリ耕耘装置において、前記傾斜耕 耘爪軸筒(3)を水平耕耘爪軸筒(1)に対して逆転駆動すべく傾斜耕耘爪軸筒(3) への伝動系を伝動軸(2)への伝動系に連動連結してあることを特徴とするもので ある。 That is, the rotary cultivator according to the present invention transmits the tilted cultivating pawl shaft cylinder (3) which is inclined at a predetermined angle with respect to the transmitting shaft (2) into which the horizontal cultivating pawl shaft cylinder (1) is fitted. A center-drive type rotary tiller for plowing the soil under the transmission case with a tiller claw (5) mounted on the inclined tiller claw shaft cylinder (3), which is disposed close to the claw (4). In order to reversely drive the tilted tillage pawl shaft cylinder (3) with respect to the horizontal tillage pawl shaft cylinder (1), the transmission system to the tilted tillage pawl shaft cylinder (3) is transmitted to the transmission shaft (2). It is characterized by being linked and linked to.

上述の構成になるロ−タリ耕耘装置において、伝動軸(2)に動力が伝達されて 水平耕耘爪軸筒(1)がダウンカット回転駆動される際、傾斜耕耘爪軸筒(3)には 水平耕耘爪軸筒(1)とは逆向きの回転動力が伝達されて、該傾斜耕耘爪軸筒に取 り付けられた耕耘爪(5)がアップカット回転して伝動ケ−ス下の土壌を耕起する のであり、アップカット回転する耕耘爪(5)の耕耘抵抗が機体のダッシュを止め る力として作用するから機体のダッシュ傾向が低められて良好な耕耘が行われる のである。 しかして、アップカット回転する耕耘爪(5)で機体のダッシュ阻止力を得るも のであるから、従来の抵抗体によるもので発生していた土壌、草藁類の付着堆積 がなくなって耕起跡に溝のできない整斉状態に耕耘できると同時に、伝動ケ−ス 下の残耕処理を耕耘爪のアップカット回転によって細土効率よく良好に行うこと ができることとなった。 In the rotary cultivator having the above-mentioned configuration, when power is transmitted to the transmission shaft (2) and the horizontal tillage pawl shaft cylinder (1) is driven to rotate down-cut, the inclined tillage pawl shaft cylinder (3) is not Rotational power in the direction opposite to that of the horizontal tillage claw shaft cylinder (1) is transmitted, and the tillage claw (5) attached to the tilted tillage claw shaft cylinder rotates upcut to rotate the soil under the transmission case. The plowing resistance of the tilling claws (5) that rotate upcut acts as a force to stop the dash of the airframe, so that the dash tendency of the airframe is reduced and good tilling is performed. Since the tilling claws (5) that rotate upcut are used to obtain the dash blocking force of the airframe, the soil and grass straw deposits and deposits that have been generated by the conventional resistor are eliminated, and the tillage trace is eliminated. At the same time, it is possible to cultivate in a balanced state where there is no groove, and at the same time, it is possible to carry out residual tillage treatment under the transmission case efficiently and finely by using the upcut rotation of the tilling claw.
