本発明は、畦に被覆された農用膜体を巻取って回収する
農用膜体の巻取回収装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an agricultural membrane winding and recovery device that winds up and collects an agricultural membrane whose ridges are coated.
(従来の技術)
トラクタの後方に牽引装着される機枠上にガイドローラ
と巻取軸とを備え、畦に沿って移動しながら、畦に被覆
された農用膜体をガイドローラを介して巻取軸に巻取る
ようにした農用膜体の巻取回収装置がある。(Prior art) A guide roller and a winding shaft are provided on a machine frame that is towed behind a tractor, and while moving along the ridge, the agricultural membrane covered on the ridge is rolled up via the guide roller. There is a winding and recovery device for agricultural membranes that is wound around a winding shaft.
従来のこの種の巻取回収装置におけるガイドローラ1は
、第8図に示すように軸心方向の中央部が最大径で、両
端に移るに従って徐々に小径となる太鼓状のもの、或い
は第9図に示すように軸心方向の全長にわたって同径の
円筒状のもの等が用いられている。As shown in FIG. 8, the guide roller 1 in a conventional take-up and recovery device of this type has a drum-like shape that has a maximum diameter at the center in the axial direction and gradually decreases in diameter toward both ends; As shown in the figure, a cylindrical one having the same diameter over the entire length in the axial direction is used.
(発明が解決しようとする問題点)
野菜栽培あとの膜体は、作物成長のため中央部に孔がお
いており、また外的条件により膜体の中央部が長平方向
に連続的に裂けていることがある。(Problems to be solved by the invention) After vegetable cultivation, the membrane has a hole in the center for crop growth, and the center of the membrane is torn continuously in the long direction due to external conditions. Sometimes there are.
従って、従来の太鼓状のガイドローラ1では、膜体を案
内する際に、膜体が両側に分がれてガイドローラlから
外れ、そのため膜体が破れて回収不能になることがあっ
た。Therefore, with the conventional drum-shaped guide roller 1, when guiding the membrane, the membrane separates into both sides and comes off from the guide roller 1, which may cause the membrane to tear and become unrecoverable.
また円筒状のガイドローラ1では、膜体の外れを防止で
きるが、膜体上の土、野菜の茎葉等の分離が悪く、これ
らを膜体と共に巻込んでしまうため、その後の作業に支
障を来す欠点があった。In addition, the cylindrical guide roller 1 can prevent the membrane from coming off, but it is difficult to separate soil, vegetable stems, leaves, etc. on the membrane, and these things get rolled up together with the membrane, which hinders subsequent work. There were some drawbacks.
本発明は、このような従来の問題点に鑑み、膜体の外れ
を防止できると共に、膜体上の土、茎葉等を確実に分離
できるようにすることを目的とする。SUMMARY OF THE INVENTION In view of these conventional problems, it is an object of the present invention to prevent the membrane from coming off and to reliably separate soil, leaves, etc. on the membrane.

The agricultural membrane body 3 is moved to the guide roller 2
0, the guide roller 20 has a large diameter section 21 at the center, and small diameter sections 22 on both left and right sides of the large diameter section 21. Each small diameter portion 22 is provided with an outer stop portion 23 having a larger diameter than the small diameter portion 22 at the outer end thereof.

In this case, as long as the membrane body 3 is not torn left and right, it will be guided by the large diameter portion 21, so the soil, leaves, etc. on the membrane body 3 can be separated left and right and dropped, and the soil, leaves, etc. can be rolled up at the same time. I won't take it away. Further, when the membrane body 3 is torn from side to side, the small diameter portion 22 guides it and the external stopper portion 23 prevents the membrane body 3 from coming off, so that the membrane body 3 does not come off from the guide roller 20 and become unwindable.

68の外れを防止するようになっている。Reference numeral 68 denotes a friction type transmission belt such as a V-belt, which is hung across the driving pulley 35 and the driven pulley 51. 69 is a tension pulley, and drive pulley 35
is pivotally connected to the tip of the tension arm 70 so as to contact the drive side 68a of the transmission belt 68 from below in the vicinity of the tension arm 70;
Further, the tension arm 70 is supported on the side frame member 10 by a pivot shaft 71 so as to be able to swing up and down, and is also supported by a tension spring 72.
is biased upward. The tension spring 72 is connected to an adjustment lever 73, and the adjustment lever 73 is connected to the side frame member 1.
The upper end of the bracket 74 is pivotally attached to the bracket 74 on the front frame member 9 by a pivot shaft 75, and is detachably engaged with a pin-shaped engagement portion 77 of a support 76 erected on the front frame member 9. There are a plurality of retaining parts 77 in the vertical direction, and when the adjustment lever 73 is locked to the lower end engaging part 77, the pressing force of the tension boob U-69 against the transmission belt 68 becomes weaker, and the drive pulley 35 and the transmission belt 68, so that slippage occurs between the two and 68. 78 is a belt guide provided along the drive pulley 35; 79 is a driven side 68b of the transmission belt 68;
A belt guide 80 is provided along the drive side, and is designed to prevent the transmission belt 68 from coming off.

上方側に位置させる。When the membrane body 3 covered with the ridge 2 is rolled up and collected using the winding and collecting device 7 having the above configuration, the following procedure is performed. That is, as shown in FIG.
Position it on the upper side.
そして、膜体3の端部側を連動軸41の下側からガイド
ローラ20の上側を通って巻取軸46に巻付けて固定し

、膜体3をはがしやすくして行く。At this time, when the output shaft 34 of the transmission case 32 rotates at a predetermined speed in the direction of the arrow a in FIG. The pair of left and right loosening claws 37 swings back and forth around the axis 39, loosening the soil in both the left and right rows of the ridge 2, breaking the soil 4 at both ends of the membrane 3 from below the membrane 3, and removing the soil from the bottom of the membrane 3. Make it easier to peel off 3.

体ロール85が絞まりすぎたりすることはない。On the other hand, since the drive boot 'J-35 fixed to the output shaft 34 rotates in the direction indicated by arrow a, the winding shaft 46 rotates in the direction indicated by arrow b in FIG. 2 via the transmission belt 68 and rotating shaft 50. While pulling the membrane 3 guided through the interlocking shaft 41 and the guide roller 20, the membrane 3 is sequentially wound into a roll at a circumferential speed synchronized with the traveling speed of the tractor 5. The drive pulley 35 always rotates at a constant speed, while the film roll 8 on the take-up shaft 46
5 gradually becomes larger in diameter as it is wound, but since the tension pulley 69 is in pressure contact with the driving side 68a of the transmission belt 68, if the circumferential speed on the winding side is to increase, then This resistance acts on the drive side 68a, and the tension pulley 69 moves downward against the tension spring 72, causing slippage between the drive pulley 35 and the transmission belt 68. Therefore, the membrane 3 is always wound up at a speed that is synchronized with the traveling speed, and the membrane 3 will not break due to abnormal tension and the membrane roll 85 will not become too narrow.

きる。The membrane 3 is guided by a guide roller 20, but unless it is torn in the longitudinal direction, the membrane 3 will be guided along the large diameter portion 21 as shown by the solid line in FIG. It is possible to drop soil, leaves, etc. forward and to the left and right without getting them involved. Furthermore, in the event that the membrane body 3 is torn, as shown by the imaginary lines in FIG. It does not come off the roller 20 and can be reliably wound.

d矢示)に簡単に抜取ることができる。When removing the membrane roll 85 from the winding shaft 46, the retaining plate 62 was removed, the bearing stand 65 was rotated around the pivot 67 in the direction of arrow C in FIG. 3, and the bearing 61 was removed from the post 54. rear,
Remove the flange 49 from the rotating shaft 50. As a result, the end of the winding member 47 of the winding shaft 46 is narrowed down as shown by the imaginary line in FIG. 3, so that the membrane roll 85 can be easily pulled out in the axial direction (arrow d in FIG. 3). You can take it.
なお、巻取回収装置7は、トラクタ5の後方に一列状に
取付けても良い。Note that the winding and recovery devices 7 may be installed in a line at the rear of the tractor 5.

る。(Effects of the Invention) According to the present invention, the guide roller 20 is
1, and small diameter portions 22 on both the left and right sides of this large diameter portion 21.
Since the outer stop portion 23 is provided with a larger diameter than that of the membrane body 3,
When guiding the film, soil, stems, leaves, etc. on it can be reliably separated, and even if the film body 3 is torn from side to side, the external stopper part 23 prevents it from coming off from the guide roller 20, making it possible to reliably wind it up. .
