方法によっても、泥の付着防止に十分な効果が得られて
いない。In order to suppress or prevent the adhesion of mud, some methods include applying vibration to the cover to remove the adhering mud, or changing the surface of the iron plate that is the material of the cover to a material that is less likely to attract or accumulate mud. Proposed. However, even with these methods, sufficient effects in preventing mud adhesion have not been achieved.

を目的とする。Therefore, the present invention promotes the formation of a water film on the surface of the cover by maintaining the cover at a positive potential, suppresses the adhesion of mud, and makes it possible for the adhered mud to easily separate from the cover. The purpose is to provide a cover for rotary type agricultural machinery.

の間に電圧を印加する手段を設けたことを特徴とする。In order to achieve the object, the present invention' provides a cover disposed on a part of the circumferentially outer side of a tilling rotor in which a large number of tilling claws are attached to the periphery of a tilling shaft installed in the horizontal direction.
The present invention is characterized in that an electrode is embedded in the cover via an insulator, and means is provided for applying a voltage between the cover and the electrode so that the cover is maintained at a positive potential.

る。In the rotary agricultural machine to which the present invention is applied, the cover is maintained at a negative potential. It is presumed that the reason why mud adhesion is suppressed by this potential is as follows. That is, cations such as potassium ions and sodium ions contained in the soil migrate toward the electrode, and an atmosphere with a high concentration of these cations is formed around the electrode. When the concentration of these cations exceeds a predetermined value, they absorb moisture from the soil and change into hydroxides. This hydroxide further absorbs moisture contained in the soil. As a result, the soil on the cover side dries out.
乾燥した土壌は、カバー表面に対する付着力が小さくな
り、カバー表面から自然に剥離する。その結果、カバー
に対する泥の付着・堆積がなくなる。Dry soil has less adhesion to the cover surface and naturally peels off from the cover surface. As a result, the adhesion and accumulation of mud on the cover is eliminated.
以下、図面を参照しながら、実施例によって本発明を具
体的に説明する。Hereinafter, the present invention will be specifically described by way of examples with reference to the drawings.
本実施例のロータリ型農業機械用カバーは、第１図に示
すように、カバー本体Ａに絶縁体Ｂを介して電極Ｃを取
り付けている。そして、カバー本体Ａと電極Ｃとの間に
、電源りから数ポルトル十数ボルト程度の電圧を印加し
、カバー本体Ａを正の電位に維持する。In the rotary type agricultural machine cover of this embodiment, as shown in FIG. 1, an electrode C is attached to a cover body A with an insulator B interposed therebetween. Then, a voltage of several volts or so is applied from a power source between the cover body A and the electrode C to maintain the cover body A at a positive potential.
電極Ｃは、電圧の印加が有効な間隔（たとえば７０ｍ）
をもって、カバー本体Ａに複数個取り付けられる。また
、絶縁体Ｂとしては、泥の付着に対して抵抗のある材料

しい。Electrode C is spaced at a distance where voltage application is effective (for example, 70 m)
A plurality of pieces can be attached to the cover main body A using the . Further, as the insulator B, it is preferable to use a material that is resistant to the adhesion of mud, such as a synthetic resin with a smooth surface.
このようにして、カバーＡと電極Ｃとの間に電圧を印加
するとき、第２図に示すように電極Ｃの近傍に土壌に含

成される。この陽イオン濃度の高い雰囲気は、吸水性が
強く、土壌中の水分を吸収する。他方、カバーＡの周辺
にある土塊Ｅは、脱水された状態Ｆとなる。In this way, when voltage is applied between cover A and electrode C, potassium ions, sodium ions, calcium ions, etc. contained in the soil are transferred to the vicinity of electrode C, as shown in Figure 2. , an atmosphere with high cation concentration is formed. This atmosphere with a high concentration of cations has strong water absorption and absorbs water in the soil. On the other hand, the clod E around the cover A is in a dehydrated state F.
この土塊Ｅの乾燥によって、カバーＡに対する付着力が
低下する。そして、この付着力が低下した土塊Ｅが、カ
バーＡの表面からこぼれ落ちるように剥離する。As this clod E dries, its adhesion to the cover A decreases. Then, the soil clod E whose adhesion has decreased is peeled off from the surface of the cover A so as to fall off.
たとえば、幅２０ｃｍ、長さ１ｍの鋼板の表面に、相互

Ｉの土塊りを付着させた後１、カバーＡと電極Ｃとの間
に１２ボルトの電圧を印加した。この状態で、土壌表面
に接触させながらカバーＡを引きずった。For example, a cover A was prepared in which a plurality of electrodes C were implanted on the surface of a steel plate having a width of 20 cm and a length of 1 m with a mutual spacing of 70 mm. This cover A has an average thickness of 3 cI.
After attaching the clod I, a voltage of 12 volts was applied between cover A and electrode C. In this state, cover A was dragged while contacting the soil surface.
そして、１時間後にカバーＡに付着している土塊Ｅの状
況を測定したところ、試験前の泥付着状況より少ない平
均厚み１．５ｃｍの泥が付着していた。When the state of the soil clod E adhering to the cover A was measured after one hour, it was found that the mud had an average thickness of 1.5 cm, which was smaller than the mud adhesion state before the test.
これに対し、電圧を印加しない場合には、同様な条件下
で試験した後の泥付着厚みは１０ｃｍに達するものもあ
った。On the other hand, when no voltage was applied, the mud adhesion thickness reached 10 cm in some cases after testing under similar conditions.
そこで、電極Ｃを装着したカバーＡを実機である耕耘機

とができた。Therefore, when cover A with electrode C attached was attached to an actual power tiller and used for actual agricultural work, it was found that
It was necessary to remove the clods of soil E that had adhered to the cover A every hour, but even after using it for one day, the average thickness was 1.
Only soil clods E of 5 cm or less were attached. Further, since the adhesion force of the earth clod E to the cover A was small, the adhered earth clod E could also be removed from the cover A with a simple operation.

Therefore, it becomes possible to use agricultural 1 liter machinery with good workability. Further, since the adhering force of the adhered mud to the cover is small, the mud can be removed from the cover with a simple operation, and the agricultural machine can always be maintained in good condition.
