本発明は、茎稈刈取作業部を具備する各種の農業機械（

るレノプロ形茎稈刈取装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to various agricultural machines (
The present invention relates to a Lenopro type stem culm reaping device used in combine harvesters, heinter harvesters, mowers, etc.
農業機械におけるレシプロ形茎稈刈取装置は、はとんど

、硬度の高い金属材料（一般には炭素工具鋼が使用され

、上記の特殊作動環境に対応しているのであるが、この

在する異物（障害物）との衝突によって生ずる刃体刃先
部の欠損、曲りや刈刃の浮き上り現象などは全く防ぎ得
ていないので、比較的短期に切味が低下してしまう問題
点を充分に払拭するものとなっていない。Therefore, when operating the reaping device, it is necessary to avoid mud etc. from entering the sliding part of the device 6 and damaging the blade tip, or foreign objects such as stones colliding with the blade tip. Because the reciprocating culm cutting device operates under unfavorable conditions, each part of the reciprocating culm cutting device is subject to loads caused by the culm cutting action, as well as from the interaction with mud, etc.
The external load described in 1 above is applied, which significantly accelerates wear and tear.For this reason, conventional reciprocating type stem culm reapers are made of highly hard metal materials (generally carbon tool steel is used). The blade receiving body and cutting blade body formed through heat treatment are used to cope with the above-mentioned special operating environment, but even with this method, the cutting edge of the blade body can be maintained in a sharp state for a long period of time. However, it has not been possible to prevent the cutting edge from chipping, bending, or lifting the cutting blade due to collisions with foreign objects (obstacles) mixed in with mud, etc. It does not sufficiently eliminate the problem that the sharpness deteriorates in a relatively short period of time.
しかも、従来装置は全体的に金属材料で形成されながら

が起るし、酸化腐蝕による鈷イ」き状態の発生も完全に
は阻止し得ないので無理に作動させると刃こばれを発生
させてしまうといった他の問題も起るのである。Moreover, although conventional devices are made entirely of metal, they operate under conditions in which sufficient lubrication cannot be maintained due to contact with mud, etc., and therefore the generation of heat-generating sintering cannot be prevented and sliding occurs. The dynamic resistance increases, causing problems such as vibration and noise, and it is not possible to completely prevent the occurrence of a cracking condition due to oxidation corrosion, so forcing the blade to work may cause the blade to break. Other problems such as storage also occur.
そこで本発明は、従来装置における上記のような問題点

揮されるようにしたことを特徴とするものである。Therefore, the present invention was carried out with the aim of solving the above-mentioned problems in conventional devices, and either the cutting blade body or the blade receiving body is made of ceramics (a non-metallic inorganic solid material manufactured by firing). This forms a reciprocating reaping device, which allows the cutting section to remain sharp for a significantly longer period of time than conventional devices, even when operating under special conditions involving mud, etc. In addition, the device is characterized in that its operation is much smoother and easier than in the conventional devices i, H, and +, and it exhibits even better durability and operability.

い状態で作動するのである。Therefore, when the stem culm is reaped in any of the embodiments, the stem culm is cut by the cooperative action of the ceramic blade and the metal blade, but this cutting operation is not continued. Ceramic blades operate while coming into contact with mud, sand, gravel, etc., but they have the characteristics of being approximately 2 to 3 times harder than metal blades and having a significantly higher Young's modulus. This prevents the cutting edge from becoming rounded and worn out or causing sagging.Also, the metal blade of the other party, which is prone to wear and sagging, is polished by sliding contact to sharpen the cutting edge. Furthermore, even if the cutting edge of the ceramic blade is chipped due to impact from an obstacle, it will remain sharp after the chipping, which improves cutting performance. Naturally, the sharpness of the blade will not deteriorate to an extreme level, and the abrasive action on the metal blade will not be impaired and the other blade will continue to maintain its sharpness, so the device will not lose its sharpness over a long period of time. It operates without any movement.

The rusted metal blade side is corrected to a sharp state due to the grinding of the ceramic blade body by resuming the operation of the tool, so that good stem culm cutting work can be performed. In addition, during operation, because one side of the blade is made of ceramics, it does not cause burnout, resulting in smooth operation with reduced sliding resistance, and due to the use of ceramics, resonance This combination of the fact that no action occurs results in operation with less noise and vibration.

Compared to conventional devices, the operation is much smoother and easier, and the device exhibits even greater durability and operability.

Although ZrO2 and ZrO2 are mentioned above, other ceramics such as the aforementioned alumina, nitride crystals other than zirconia, and silicon carbide are also fully expected to have similar effects. The reason for this is that the unique characteristics of ceramics, such as high hardness, high strength, high Young's modulus, and corrosion resistance, are utilized compared to conventional metal materials. The characteristics of typical ceramics are shown in the table below in comparison with those of metals.

Furthermore, the blade body which is riveted in the examples can be removed by any suitable fixing means other than riveting! In some cases, there may be several configurations that allow for easy replacement of individual blades.
