【考案の詳細な説明】 この考案は煙草の苗などを植付けるためのかまぼこ形の
畦の上面に、軟質薄ビニールの帯状フィルムを張設する
ためのフィルム張設装置に関するものである。[Detailed Description of the Invention] This invention relates to a film stretching device for stretching a strip-shaped film of soft thin vinyl over the upper surface of a semicylindrical ridge for planting tobacco seedlings and the like.

畦立機を用いて、このようなかまぼこ形に成形したとき
、山形状横断面の左右肩部から裾附近までの間の鎮圧が
不充分になり勝ちで、このため、引続く帯状フィルムの
張設作業の際、左右肩部附近が崩落することも多く畦の
成形が不均一となり、又、このため、畦上面に対する帯
状フィルムの沿いも悪く、短時日のうちにはがれてしま
うなどの欠点があった。When forming into such a semi-cylindrical shape using a ridge forming machine, the compression between the left and right shoulders of the chevron-shaped cross section to the vicinity of the hem tends to be insufficient, and as a result, the subsequent stretching of the strip-like film is difficult. During installation work, the area around the left and right shoulders often collapses, resulting in uneven formation of the ridge, and as a result, the band-like film does not adhere well to the top of the ridge, resulting in disadvantages such as peeling off within a short period of time. Ta.

そこでこの考案は、従来のフィルム張設装置のように、
畦の頂部と肩部に限ってそれぞれ鎮圧できるローラーを
設けただけでなく、さらに畦の裾部の鎮圧もできるよう
裾部ローラーを配設して、畦の全面の鎮圧を充分に行い

Not only are we equipped with rollers that can compress only the top and shoulders of the ridge, but we have also installed hem rollers that can compress the hem of the ridge, while fully compressing the entire surface of the ridge. The purpose is to provide a tensioning device configured to uniformly tension a strip-shaped film. Horizontal left and right vertical rods 4, 4 are installed rearwardly on the horizontal rod 3 of the installation device 2, and immediately behind the horizontal rod 3, an arm 5.5 is attached from the vertical rods 4, 4, the vertical position of which can be adjusted freely. is extended, and a film roll 1 on which a band-shaped film 6 is wound is rotatably mounted between the arms 5, 5.

縦杆１２に順次、取付ける。As shown in the figure, the ridges 9 having a mountain-shaped cross section are successively formed below the film roll 7 by the ridge plate 8 connected to the power agricultural machine 1 at the same time. Immediately after step 7, the mountain-shaped film guide 10 and the mountain-shaped film guide 11 along the upper surface of the ridge 9 are sequentially attached to the central vertical rod 12 extending rearward from the left and right center portions of the horizontal rod 3. .

A drum-shaped shoulder roller 14, 14 along the ridge 9 is rotatably supported on the rear horizontal rod 13, and a drum-shaped top along the top of the ridge 9 is provided at the left and right center of the rear horizontal rod 13. roller 15
In addition, A5 cylindrical hem rollers 16, 16 are provided at the hem of the ridge 9 at both left and right ends of the rear transverse rod 13, slightly rearward in the direction of travel than the shoulder rollers 14 and 14, respectively. Each is rotatably supported.

A soil covering disk 19 is rotatably supported, respectively, and the pressing wheels 18, 18 and soil covering disks 19, 19 are brought into contact with the ground surface at the edge of the ridge 9 behind the hem rollers 16, 16. There is.

そして、フィルムロール７から後方へ引出した帯状フィ

16 rotates as the film stretching device 2 moves forward while pressing the strip film 6 against the entire surface of the ridge 9, and the pressing wheels 18, 18 press the strip film 6 against the entire surface of the ridge 9. Press and rotate the vicinity of the left and right edges of 6 onto the ground surface at the edge of ridge 9,
Further, the soil covering disks 19, 19 cover the crushed soil at the edge of the ridge 9 on both left and right sides of the strip film 6 to prevent the strip film 6 from moving.

この考案に係るフィルム張設装置は上述のように、肩部
ローラー１４．１４及び、頂部ローラー１５と裾部ロー
ラー１６．１６とによって、帯状フィルム６を山形状の
畦９の全面にわたって押圧せしめるよう構成しているの
で、畦立板８によって形成された脆弱な山形状の畦９は
、これらの各各のロールによってその全面を鎮圧される
ことになり、このため、最も崩れ易い左右の肩部９ ａ
ｔ９８附近も左右の肩部ローラー１４．１４によって
充分に鎮圧されて肩部９ａ 、９ａの上潮れが無くなる
ものであり、さらに、畦９の頂部及び裾部も夫々、頂部
ローラー１５及び裾部ローラー１６゜１６によって鎮圧
されるので、畦９の全面が良く鎮圧される結果、従来の
装置のような欠点、即ち、畦の一部の鎮圧動作によって
鎮圧された部分の土が鎮圧されない側に膨出して鎮圧部
と非鎮圧部との境果附近で土が崩れ易くなると云う欠点
を、この考案装置は良く解消できたのである。As described above, the film stretching device according to this invention presses the band-shaped film 6 over the entire surface of the mountain-shaped ridge 9 by the shoulder roller 14.14, the top roller 15, and the bottom roller 16.16. As a result, the fragile mountain-shaped ridges 9 formed by the ridge-standing plates 8 are compressed on their entire surface by these respective rolls, so that the left and right shoulders, which are most likely to collapse, are 9a
The area around t98 is also sufficiently suppressed by the left and right shoulder rollers 14 and 14, eliminating the upper flow of the shoulders 9a and 9a.Furthermore, the top and hem of the ridge 9 are also compressed by the top roller 15 and the hem, respectively. Since the compaction is performed by the rollers 16° 16, the entire surface of the ridge 9 is well compacted, and as a result, there is no problem with conventional devices, namely, the soil in the compacted part is moved to the uncompacted side due to the compaction operation of a part of the ridge. This devised device successfully solved the problem that the soil swells and tends to collapse near the boundary between the suppressed and non-suppressed areas.

そのうえ、このように抑圧成形された畦９に張設された
帯状フィルム６は、畦９の山形状に沿って均一に張設さ
れることができるのである。Moreover, the strip-shaped film 6 stretched over the ridges 9 formed by compression molding in this manner can be stretched uniformly along the mountain shape of the ridges 9.

以上のように、この考案のフィルム張設装置は、山形状
の畦の鎮圧成形とフィルムの均一な張設作業を能率良く
行い得る優れた効果を奏するものである。As described above, the film tensioning device of this invention exhibits an excellent effect of efficiently performing pressure forming of mountain-shaped ridges and uniform tensioning of the film.
