取付けた刈取収穫機の刈高さ検出装置に関する。[Detailed description of the invention] The present invention has a cutting rod that presses and guides the stem culm that is not to be harvested toward the outside of the vehicle body, and extends it toward the outside of the vehicle body on the side of the reaping section that can be lifted and lowered relative to the vehicle body. The reaping harvester is provided with a non-contact type height detection sensor that can be operated to switch between an operating position in which the reaping unit is exposed and a storage position in which the reaping unit is retracted to the side of the reaping unit, and a non-contact height detection sensor that detects the height of the reaping unit from the ground is attached to the reaping unit. This invention relates to a cutting height detection device for a machine.

い不利があり、改善の余地があつた。 Conventionally, a special cover body is provided to cover the height detection sensor to avoid contact with the stem culm or other objects, but in this case, the sensor cover body must be specially provided. Due to this, there is a disadvantage that the number of parts increases or the number of assembly steps increases. For this reason, the present applicant focused on the weeding tool attached to the front end of the cutting section and proposed a means of entering and placing the weeding tool in the back part of the weeding tool. In order to reliably cover the sensor, there is a disadvantage that the weeding tool must be modified, such as by making it larger, and there is room for improvement.
本考案は、上記実状に鑑みて為されたものであ
り、その目的は、本来構成を有効利用した簡単な
改造によつて、高さ検出センサーを茎稈や他物と
の接触を回避させた状態で設ける点にある。 The present invention was developed in view of the above-mentioned circumstances, and its purpose is to avoid contact of the height detection sensor with the stem culm or other objects through simple modification that makes effective use of the original structure. The point is that it is provided in a state.
本考案による刈取収穫機の刈高さ検出装置の特
徴構成は、前記高さ検出センサーを、平面視にお
いて前記分草杆の移動全範囲において前記分草杆
よりも車体内方側に位置させる状態で前記刈取部
の横側部に配置した点にある。 A characteristic configuration of the cutting height detection device for a reaping harvester according to the present invention is such that the height detection sensor is located inward of the vehicle body than the grass dividing rod in the entire movement range of the grass dividing rod in plan view. and is located on the lateral side of the reaping section.
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、非刈取対象茎稈が刈取部側に倒れ込

ーを覆つて、茎稈や他物がセンサーに接触するこ
とを回避させるようにしてある。 In other words, we focused on the weeding rod that is provided to prevent the non-reaping target stem culm from falling toward the reaping part,
The weeding tool can be used to cover the height detection sensor and detect stem culms or other objects, not only during reaping work when the weeding tool is switched to the working position, but also when driving on the road when the weeding tool is switched to the retracted position. It is designed to avoid contact with the sensor.
従つて、既設の分草杆を有効利用して、それよ

実用上の利点大である。 Therefore, by making effective use of the existing grass dividing rod and positioning it further inside the vehicle body, the height detection sensor can be placed on the side of the cutting section, which is an extremely simple modification. This prevents the detection sensor from being damaged due to contact with the stem culm or other objects.
This has great practical advantages.
