で設けた制御機構付トラクタに関する。[Detailed Description of the Invention] The present invention includes a flat upper wall part that is located on the side of the driver's seat and covers the upper part of the rear wheel, and extends downward from the front end of the flat wall part. A control mechanism that connects a working device to the rear of a tractor provided with a rear wheel fender with a flat front wall portion by a drive device such that its connection attitude to the tractor can be freely changed, and automatically operates the drive device. The present invention relates to a storage case for an electric control circuit unit constituting a storage case, and a tractor with a control mechanism installed in a connecting corner between the fender top wall and the fender front wall.

な衝撃を与えて電気制御回路部のトラブルを招く
虞れがあり、改善の余地があつた。 The above-mentioned tractor makes effective use of the connecting corner between the upper wall and the front wall in the rear wheel fender to insert the storage case into the rear wheel fender. This method has the advantage that the storage case can be installed inside the fender while avoiding an increase in the height of the upper wall of the fender compared to other methods such as attaching a storage case. Because the bottom wall of the storage case was formed into a flat surface along the horizontal plane, the rear end of the bottom wall of the storage case, which was in a position crossing the outer circumference of the rear wheel, was close to the outer circumference of the wheel and was attached to the outer circumference of the wheel. When the soil clods came into contact with the rear end of the bottom wall, there was a risk that a large impact would be applied to the storage case, causing trouble in the electrical control circuit, and there was room for improvement.

に形成することになり、上記不都合を招くものと
なつていた。 More specifically, in recent years, electronic components constituting the electric control circuit section have been attached to a board to facilitate assembly work, but conventionally, the board has been installed in an upright position. Because of this, the top and bottom width of the storage case is large, and
The bottom wall of the storage case is formed in a horizontal plane along the lower edge of the substrate, which causes the above-mentioned inconvenience.
本考案は、上記実状に鑑みて為されてものであ
つて、その目的は、簡単な改造によつて、収納ケ
ース底壁と後輪外周面との間隔を、底壁全体に亘
つて大きくすることができるようにする点にあ
る。 The present invention was developed in view of the above-mentioned circumstances, and its purpose is to increase the distance between the bottom wall of the storage case and the outer peripheral surface of the rear wheel over the entire bottom wall by simple modification. The point is to make it possible.

用基板を、横倒れ姿勢で設置すると共に、前記収
納ケースの底壁を、後輪の外周面に平行あるいは
それに近い状態となるように、後端側ほど上方に
位置する状態に傾斜させた点にある。 The characteristic configuration of the tractor with a control mechanism according to the present invention is that the electronic component mounting board constituting the electric control circuit section is installed in a sideways position, and the bottom wall of the storage case is parallel to the outer peripheral surface of the rear wheel. Or, in order to achieve a state close to that, the rear end is tilted upwardly.
次に、本案特徴構成による作用効果を述べる。 Next, the effects of the feature configuration of the present invention will be described.
すなわち、電子部品取付用基板を上下巾の小さ
な状態で収納できるものとなつて、収納ケースの
上下巾を小さくでき、しかも、収納ケース底壁

無い状態に位置させることができる。 In other words, the electronic component mounting board can be stored with a small vertical width, the vertical width of the storage case can be reduced, and the bottom wall of the storage case is partially close to the outer peripheral surface of the rear wheel. It can be positioned without any parts.
従つて、収納ケースをフエンダ内における角部

タを得るに至つた。 Therefore, while taking advantage of the above-mentioned advantage of allowing the storage case to fit into the corner of the fender, the space between the bottom wall of the storage case and the outer circumferential surface of the wheel is made large over the entire bottom wall, thereby preventing the storage case from receiving a large impact. It is possible to achieve good control over a long period of time while ensuring that no damage is caused.
As a result, we have achieved a tractor with a control mechanism that can be used even better.

At the same time as installing the double-acting type fluid pressure cylinder 9
A sensor 11 is attached to the rolling operation cylinder 9. The sensor 11 detects the extended/contracted position of the tiller 7 as the rolling attitude of the tiller 7 relative to the tractor rolling position, and outputs the detection result as a fluctuation in the voltage signal 1. Based on the signal θ from the inclination angle sensor 10, the cylinder 9 of the tilling device 7 relative to the horizontal plane is
A calculation circuit 12 calculates the target expansion/contraction position of the motor and outputs a voltage signal L0 accordingly, and compares and discriminates the signal L0 from the signal L0 with the signal l of the rolling sensor 11, and accordingly determines the electromagnetic Operation circuit 14 for extending and shortening the cylinder control valve 13
A discriminating circuit 15 is provided to selectively operate A and 14B, so that the horizontal inclination angle of the tilling device 7 with respect to the horizontal plane is maintained within a set range.
