Description

本発明は、圃場に畝等の起伏があっても適切に走行することができる移動農作業機に関するものである。   The present invention relates to a mobile farm work machine that can travel appropriately even if there are undulations such as ridges in a farm field.

従来移動用農作業機としては、特許文献１に示されるように、圃場を走行しながら地上に伸びる生姜等の茎葉を掴んで引き抜き、地中の収穫部分を地上に引き上げるものがある。
特開２００６−１０９７８３ As a conventional agricultural farm machine for movement, as disclosed in Patent Document 1, there is a machine that pulls out the ground harvested portion to the ground by grabbing and pulling a ginger and other leaves extending on the ground while running on the field.
JP 2006-109783 A

しかしながら、特許文献１に記載される移動農作業機は、左右後駆動輪と左右前転輪の４輪で圃場を走行するため、圃場の起伏等により、走行姿勢を乱されることがあった。
また、旋回動作を行う際、左右前転輪を浮かせるために、作業者はハンドル等を押し下げて機体前側を持ち上げる必要があり、作業者に多大な負担がかかっていた。 However, since the mobile farm work machine described in Patent Document 1 travels on the field with four wheels, that is, the left and right rear drive wheels and the left and right front wheels, the traveling posture may be disturbed due to ups and downs of the field.
Further, when performing the turning operation, in order to lift the left and right front wheels, the operator needs to push down the handle or the like to lift the front side of the machine body, which places a great burden on the operator.

さらに、左右後駆動輪及び左右前転輪の上下位置を変更できないため、畝上に左右片側の車輪を乗せ、左右他側の車輪を畝溝を走行させて作業をする場合、機体が左右一側に傾斜した状態で引抜作業を行わねばならず、引抜作業が上手く行われないことがあった。   Furthermore, since the vertical positions of the left and right rear drive wheels and the left and right front wheels cannot be changed, when the left and right wheels are placed on the ridge and the left and right wheels are driven in the ridge groove, The pulling work must be performed in a state inclined to the side, and the pulling work may not be performed well.

本発明は、上記の課題を解決するために次の技術的手段を講じた。
請求項１記載の発明は、機体の前後一側方に設けたミッションケース（４）からの駆動力で駆動される左右第１車輪（２５，２５）と左右第２車輪（２６，２６）を設けたと共に、機体の前後他側方に左右第３車輪（２８，２８）を設け、該左右第１車輪（２５，２５）と左右第２車輪（２６，２６）と左右第３車輪（２８，２８）とを略水平に接地させた状態と、左右第１車輪（２５，２５）もしくは左右第２車輪（２６，２６）の一方を下降させ、且つ左右第３車輪（２８，２８）を下降させた状態とに切り換え自在に構成したことを特徴とする移動農作業機とした。 The present invention has taken the following technical means in order to solve the above problems.
According to the first aspect of the present invention, the left and right first wheels (25, 25) and the left and right second wheels (26, 26) driven by the driving force from the transmission case (4) provided on one side of the front and rear of the airframe are provided.
