〔産業上の利用分野〕
本発明は対地作業装置に関し、詳しくは、対地作業装置
を用いて行・う作業の能率を向上させるための技術に関
する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a ground work device, and more particularly to a technique for improving the efficiency of work performed using a ground work device.
対地作業装置としてロータリ耕耘装置を例に挙げると、
通常、ロークリ耕耘装置は農用Ｉ・ラクタの車体の後端
に連結され、又、このロークリ耕耘装置での作業は、−
耕起行程を終えて車体が枕地に達する毎に車体を１８０
度旋回させて次の耕起行程を開始することで行われる。Taking a rotary tiller as an example of a ground work device,
Normally, the rotary tiller is connected to the rear end of the agricultural tractor's vehicle body, and the work with this rotary tiller is -
Every time the vehicle reaches the headland after completing the plowing process, the vehicle is
This is done by turning the plow once and starting the next plowing process.
つまり、従来の作業では耕起作業が行われる圃場が矩形
であっても、この圃場の畦際には少なくとも２箇所の枕
地が形成されているのである。In other words, in conventional work, even if the field on which plowing work is performed is rectangular, at least two headlands are formed along the ridges of this field.
しかし、前述のように車体が畦際に達する毎に車体を旋
回させる作業では、畝起こし作業のように車体の走行間
隔を一定に維持しなげればならない作業における車体の
旋回操作に作業者が注意を払わねばならないばかりか、
枕地の未朝起部分の耕起も改めて行わねばならず改善の
余地がある。However, as mentioned above, when the car body is rotated every time it reaches the edge of a ridge, it is difficult for the worker to turn the car body when the car body must maintain a constant travel distance, such as when raising ridges. Not only do we have to be careful, but
The areas of the headland that have not yet been plowed in the morning must be plowed again, and there is room for improvement.
本発明の目的は合理的な改造によって、できるだけ能率
高く作業を行える対地作業装置を得る点にある。An object of the present invention is to obtain a ground-based working device that can perform work as efficiently as possible through reasonable modification.
本発明の特徴は、農用トラクタの車体（１）の左右方向
の中央を略境として車体の一側方へ張出す姿勢に切換変
位する機構を備えてある点にあり、その作用、及び効果
は次の通りである。The feature of the present invention is that it is equipped with a mechanism that switches and displaces the vehicle body (1) of the agricultural tractor to a posture that extends to one side of the vehicle body approximately at the center in the left-right direction, and its operation and effects are as follows. It is as follows.
」二記特敬を例えば第１図に示すように構成すると、車
体（１）を後進させて行う耕起作業の行程の終端に車体
（１）が達した場合には、そのま走行することで対地作
業装置（５）を畦（Ａ）の極めて近傍まで近づける状態
で作業が行えると共に、次の耕起行程に移る場合には対
地作業装置（５）の姿勢を切換え、か・つ、車体（１）
を前進さ−ｅるごとで車体（１）を旋回さゼること無く
次の耕起作業行程に移れることになる。For example, if the second special call is configured as shown in Figure 1, when the vehicle body (1) reaches the end of the plowing process performed by moving the vehicle body (1) backwards, it will continue to drive. You can work with the ground working device (5) very close to the ridge (A), and when moving on to the next plowing process, you can change the posture of the ground working device (5) and move the vehicle body. (1)
Each time the vehicle moves forward, it is possible to move on to the next plowing operation without having to turn the vehicle body (1).
従って、対地作業装置を姿勢切換ｉｉＪ能に構成する改
造によって、１つの畦際での車体の旋回操作の省略と枕
地を改めてＤ１起する手間が省（・Ｊることから能率高
く作業を行える対地作業装置が得られた。Therefore, by modifying the ground work device so that it can switch postures, the work can be done more efficiently by eliminating the need to turn the car body at the edge of a ridge and the trouble of raising D1 again on the headland. Ground work equipment was obtained.
