第１作業棒１６の先端部には作業棒連結具１３によって連結ピン１５を介して第２フレーム１２が取り付けられ、第２フレーム１２の先端にフレーム接合ピン１１を介して第１フレーム８が回動可能に取り付けられている。また、第２フレーム１２と第１フレーム８との間にはスプリング９が張架され、このスプリング９の作用により第１フレーム８が回動されて、絵鈍角または鋭角に角度を自在に変えられるようにされている。 The second frame 12 is attached to the distal end portion of the first working rod 16 via the coupling pin 15 by the working rod coupling tool 13, and the first frame 8 is rotated to the distal end of the second frame 12 via the frame joining pin 11. It is mounted movably. In addition, a spring 9 is stretched between the second frame 12 and the first frame 8, and the first frame 8 is rotated by the action of the spring 9, so that the angle can be freely changed to an obtuse angle or an acute angle. Has been.

前記第１作業棒１６および第２作業棒１８内には、収穫網１を開閉作動させる開閉網作動棒１４が配され、この開閉網作動棒１４の基端部は収穫網開閉ハンドル２１に連結され、その開閉網作動棒１４の先端部は開閉紐３に連結されている。ここで、開閉紐３は、ワイヤーロープ、ピアノ線、バネ線、形状記憶合金などのスプリング作用を有する素材よりなっている。この開閉紐３が、収穫網１の口部に設けられるスライド環２に挿通され、その先端部が開閉紐取付具４に連結されている。 In the first work bar 16 and the second work bar 18, an open / close net operating bar 14 for opening and closing the harvesting net 1 is disposed, and a base end portion of the open / close net operating bar 14 is connected to a harvest net open / close handle 21. The tip of the opening / closing net operating rod 14 is connected to the opening / closing string 3. Here, the opening / closing string 3 is made of a material having a spring action such as a wire rope, a piano wire, a spring wire, or a shape memory alloy. The opening / closing string 3 is inserted into a slide ring 2 provided at the mouth of the harvesting net 1, and its tip is connected to an opening / closing string attachment 4.

また、前記開閉紐取付具４は、蔕のじくを刃物６の先を両側に挟む二枚設置の切断作動具５に取り付けられ、この切断作動具５と刃物６との間で果実の蔕のじくを挟み込んで切断するようになっている。ここで、刃物６は刃物取付ボルト７によって第１フレーム８に取り付けられている。 Further, the opening / closing string attachment tool 4 is attached to a two-piece cutting operation tool 5 that sandwiches the edge of the blade 6 on both sides, and the fruit folds are placed between the cutting operation device 5 and the blade 6. It is designed to be cut by sandwiching the film. Here, the blade 6 is attached to the first frame 8 by a blade attachment bolt 7.

また、図３に示されるように、前記切断作動具５には、収穫網１が開いたときに刃物６を囲う刃先カバー１７が固着されており、これによって、安全に収穫網１から果実の取り出しができるようにされている。 Further, as shown in FIG. 3, a cutting edge cover 17 that surrounds the blade 6 when the harvesting net 1 is opened is fixed to the cutting operation tool 5, so that the fruit can be safely removed from the harvesting net 1. It can be taken out.

本実施形態の果実収穫装置は以上のように構成されているので、果実の収穫に際しては、まず第１作業棒１６と第２作業棒１８とを伸縮操作して、その長さを収穫果樹の高さに合わせて設定した後、果実の成る角度に合わせるために収穫網１を木の幹などに当て、第１フレーム８の角度をスプリング９の作用で調整する。なお、微小角度については開閉紐３のスプリング作用で調整される。 Since the fruit harvesting apparatus of the present embodiment is configured as described above, at the time of fruit harvesting, first, the first work bar 16 and the second work bar 18 are telescopically operated, and the length of the harvested fruit tree is adjusted. After setting according to the height, the harvesting net 1 is applied to a tree trunk or the like to adjust the angle of the fruit, and the angle of the first frame 8 is adjusted by the action of the spring 9. The minute angle is adjusted by the spring action of the opening / closing string 3.

次に、収穫しようとする果実に収穫網１を被せて収穫網開閉ハンドル２１を引くと、開閉網作動棒１４を介して開閉紐３が作動し、スライド環２を介して収穫網１の収穫口が果実の表面を滑り、蔕のじくを開閉紐取付具４で刃物６の先に導き寄せるようにして収穫網１が収縮する。この収縮に伴って、蔕のじくが刃物６と切断作動具５との間に挟み込まれて切断され、果実が収穫網１内に収穫される。 Next, when the fruit to be harvested is covered with the harvesting net 1 and the harvesting net opening / closing handle 21 is pulled, the opening / closing string 3 is actuated via the opening / closing net actuating rod 14, and the harvesting net 1 is harvested via the slide ring 2. The mouth net slides on the surface of the fruit, and the harvest net 1 contracts as if the folds of the straw are guided to the tip of the blade 6 by the opening / closing string attachment 4. Accompanying this contraction, the straw is sandwiched and cut between the blade 6 and the cutting operation tool 5, and the fruit is harvested in the harvest net 1.

収穫後に収穫網ハンドル２１を離すと、開閉網スプリング１９の作用で開閉網作動棒１４が作動し、開閉紐３でスライド環２を介して収穫網１と切断作動具５が開いて、切断作動具５に固着された刃先カバー１７が刃物６の先を囲う。こうして、安全に収穫網１から果実を取り出し収穫することができる。 When the harvesting net handle 21 is released after the harvesting, the opening / closing net operating rod 14 is actuated by the action of the opening / closing net spring 19, and the harvesting net 1 and the cutting operation tool 5 are opened via the slide ring 2 by the opening / closing string 3, thereby performing the cutting operation. A blade edge cover 17 fixed to the tool 5 surrounds the edge of the blade 6. In this way, it is possible to safely extract and harvest the fruit from the harvest net 1.

本実施形態の果実収穫装置によれば、第１作業棒１６と第２作業棒１８とを伸縮操作して果実の高さに合わせて収穫作業ができるので、脚立や木登りでの危険な収穫作業から解放されるという利点がある。また、木の裏側などいろいろな成り方をする果実に、変角度に作動する第１フレーム８とスプリング作用のある開閉紐３で対応し、果実を確実に収穫網１に掴むことができる。また、開閉紐３は３ｍｍ程度の細いものを使用し、第１フレーム８として薄いものを使用すれば、果実の蔕のじくは短く狭い隙間に入り、そのじくをより確実に切断することができる。 According to the fruit harvesting apparatus of the present embodiment, the first working bar 16 and the second working bar 18 can be expanded and contracted to perform the harvesting operation in accordance with the height of the fruit. Therefore, dangerous harvesting with a stepladder or climbing a tree is possible. There is an advantage of being freed from work. Moreover, the fruit which carries out various forms, such as the reverse side of a tree, respond | corresponds with the 1st flame | frame 8 which operates at a variable angle, and the opening-and-closing string 3 with a spring action, and can hold | grip a fruit to the harvest net 1 reliably. Moreover, if the opening and closing string 3 is a thin one of about 3 mm and a thin one is used as the first frame 8, the fruit folds will enter a short narrow gap, and the folds will be cut more reliably. Can do.
