イルムで覆い、このフイルム側Ｒは畝の両側下端箇所の
溝内に埋設しており、その溝には何等フイルムが被覆さ
れていなかった。Conventionally, as shown in Fig. 34, in cultivated land where ridges are formed, the grooves between the ridges are generally about 20 cm to 30 cm. The film side R was buried in grooves at the lower ends of both sides of the ridge, and the grooves were not covered with any film.

ところが、フイルムを被覆しない溝には、端草ｊが生え
、これを略定期的に除草しなければならず、その作業も
大変に面倒であった。However, weeds grow in the grooves that are not covered with the film, and these must be weeded almost regularly, which is very troublesome work.

また、畝に被覆したフイルムの存在で、畝表面の地温は
上昇し、作物等に好影響を及ぼすが、その地温もフィル
ム被覆しない溝から逃げるものであった。Furthermore, the presence of the film covering the ridges increases the soil temperature on the surface of the ridges, which has a positive effect on crops, but the soil temperature also escapes from the grooves not covered with the film.

また、畝４内に浸みこんだ雨水は、そのフイルム被覆し
ない溝から早期に蒸散している現状である。In addition, the rainwater that has soaked into the ridges 4 is currently evaporating quickly from the grooves that are not covered by the film.

このような欠点または全面に被覆することが近時切望さ
れている。Recently, there has been a strong desire to cover such defects or the entire surface.

しかし、従来公知のフイルム被覆装置や、畝成形及びフ
イルム被覆装置では、畝と溝とにフイルムを全面に被覆
することは不可能であった。However, with conventionally known film coating devices and ridge forming and film coating devices, it has been impossible to cover the entire surface of the ridges and grooves with the film.

、フイルム被覆ができなくなるものであった。As shown in Fig. 35, this known device plows at a tilling section a, forms ridges at a younger forming section b at the rear thereof, spreads a film C over the ridges at this rear part, and presses the side edges of the film C. ring d
The method is to apply pressure with the soil and cover the ridges with a film using the covering tool e, and when working to cover the grooves with the film, the first outgoing ridge can be covered neatly, but this When the work is reversed to cover the return ridge with a film, the edge of the film C that has already been covered will be pulled or scratched by the yuzuki blade at the end of the tilling section A, causing damage and making it impossible to cover the film with the film.

業が続行できなくなるものであった。In addition, when forming ridges in the ridge forming part b without providing the tilling part a, the side edge of the already covered film C may be pulled and damaged by the side of the ridge forming part b during the operation after being turned over. ,
The ridges already coated with the film would be destroyed, making it impossible to continue the film coating operation.

また、フイルムＣを溝に被覆させると、反転させて被覆
作業するときに、覆土具ｅがフイルムＣの上側となって
、覆土できないことは勿論、既に被覆したフイルムＣ側
縁を破損させるものであった。Furthermore, if the grooves are covered with film C, when the film C is turned over and the covering work is carried out, the covering tool e will be on the upper side of the film C, which not only makes it impossible to cover the soil, but also damages the side edges of the film C that have already been covered. there were.

。Therefore, the present invention has developed a method and apparatus that can form ridges and coat the ridges and grooves of a spear with a film. First, ridges are formed in the ridge forming part, and in the case of a single ridge, the ridges that have already been formed are covered with a film. In the case of multiple ridges, one ridge that has already been formed and the other ridges other than the one ridge that has been formed are coated with a film, including the grooves, to prevent damage to the film by tilling blades, etc., and to prevent the ridges from being damaged. This eliminates damage to the film by not destroying the ridges already formed on the sides of the forming plate, and also improves efficiency by reversing the film holder and treading wheel via a swing rod for covering the film on the reciprocating path.

次に、畝成形と同時に、それらにフイルムを全面に被覆
する方法について述べる。Next, a method for covering the entire surface of the ridges with a film at the same time as forming the ridges will be described.

まず、２条畝成形型のものについて説明する。First, the two-row ridge molding type will be explained.

最初の往路２条畝を成形する前に、揺動杆１３を垂直状
にし、且つその水平支杆１８を揺動杆１３の上方部に上
げ、踏圧輪３６が畝と畝との間の溝を踏圧できないよう
に持ち上げておく。Before forming the first outward two-row ridge, the swinging rod 13 is made vertical, and its horizontal support rod 18 is raised to the upper part of the swinging rod 13, and the treading wheel 36 is inserted into the groove between the ridges. Raise it so that it cannot be pressed.

そして、耕耘部３を駆動させつつ畝成形部６にて最初の
往路２条畝を成形する（第２４図、第２８図の最も左側
の上向きの矢印参照）。Then, while driving the cultivating section 3, the first outward two-row ridge is formed in the ridge forming section 6 (see the leftmost upward arrow in FIGS. 24 and 28).

それによって２条畝と、その外側の溝が畝成形板７の側
部と排土板８副畝成形板９とにて成形される。As a result, a two-row ridge and a groove on the outside thereof are formed by the side portions of the ridge forming plate 7 and the earth removal plate 8 and the sub-ridge forming plate 9.

そして本発明装置を反転させる。そのとき、揺動杆１３

その被覆途中で、フイルム２６の側縁及び中間（溝に被
覆した箇所）に人手によって土を一定間隔（例えば約１
ｍ乃至２ｍ）に載せておく。During the covering, soil is manually added to the side edges and the middle of the film 26 (where the grooves are covered) at regular intervals (for example, approximately 1
m to 2 m).

これは、本発明装置を進行させつゝ、その耕地の土をひ
ろって放てきして載せてゆく。As the device of the present invention advances, soil from the cultivated land is collected, thrown out, and placed on top of the soil.

そして再び本発明装置を反転する。Then, the device of the present invention is turned over again.

そして再び揺動杆１３を約１８０°揺動させて止着する
。Then, the swinging rod 13 is swung approximately 180 degrees again and fixed.

The last ridge is covered with the film 26 manually.

また、４条畝以上の畝成形型のものについて、３条畝成
形型のものと同様に行なう。Also, for molds with 4 or more ridges, the same procedure as for molds with 3 ridges is carried out.

次に作用効果について説明する。Next, the effects will be explained.

掛けたり、破いたりして何等損傷しないものにできる。First, in the invention of the method of simultaneously forming the ridges and covering the entire surface with a film as described in claim 1, at the same time as forming the outward single-row ridge, the previous single-return ridge that has already been formed is covered with a film. Covering the film 26 and inverting it,
At the same time as forming a single inward ridge next to it, a film 26 is coated on the forward single ridge in front of it, and these film 2
6.26 By overlapping the side edges with each other and repeating them sequentially, the film 26 is not applied to the ridge immediately after forming a single ridge, but the film 26 is always applied to the already formed single ridge. By covering the film 26, the tilling blade at the end of the tilling section 3 can catch or tear the side edges of the already coated film 26, thereby preventing any damage.

このだめ、フイルム２６．２６側縁相互を整然と重合で
き、しかも、その重合で、畝と畝との間の溝までもフイ
ルム２６を被覆することができる。As a result, the side edges of the film 26 and 26 can be polymerized in an orderly manner, and even the grooves between the ridges can be covered with the film 26 by the polymerization.

このように畝成形とフイルム被覆を行なうことで、極め
て能率的且つ整然として畝成形と同時に、それらにフイ
ルム２６を全面に亘って被覆することができる。By performing the ridge forming and film coating in this way, it is possible to form the ridges and simultaneously cover the entire surface with the film 26 in an extremely efficient and orderly manner.

以上のように１条畝及び溝に全面にフイルム２６を整然

The soil temperature does not dissipate from the ground, and the soil temperature in the ridges can be kept at a suitable temperature, which has a positive effect on crops.Furthermore, the film 26 covers even the grooves of rainwater that has seeped into the inside of the ridges. Because of this, rainwater does not evaporate and remains in the ridges for an extremely long time.
It is good for crops etc.

The other ridges except one on the unformed ridge side are covered with the film 26, and then the film 26 is reversed and a plurality of return ridges are formed next to it, and at the same time, one ridge of the previous plurality of outbound ridges is covered with the film 26. and the other ridges except for one ridge on the unformed ridge side among the plurality of ridges on the return trip, the film 26 is coated with the film 26.
By overlapping the side edges of 26 and repeating them sequentially, all the ridges are not simultaneously covered with the film 26 immediately after forming the multiple ridges.
The other ridges other than one of the previous multiple ridges that have already been formed and one of the multiple ridges that have been currently formed will always be covered with the film 26, and even if the work is reversed, the ridges that have already been covered will be covered with the film 26. One ridge is always interposed between the side edge of the film 26 and the ridge forming part 6, and the tilling blade at the end of the tilling part 3, the side part of the ridge forming part 6, etc. The film 26.2 is removed at the groove without any damage to the side edges of the film 26.
The six side edges can be overlapped with each other in an orderly manner, and at the same time as forming a plurality of ridges, the ridges and grooves can be coated with the film 26 orderly and reliably over the entire surface.
