In this way, the box-shaped case part 30 can be placed in a storage state in which objects falling from the opening 20i can be stored in the lower region of the opening 20i, and in a storage state in which it can be swung downwards from the storage state in the lower region of the opening 20i. It is configured so that the state can be changed to an open state in which the lower region is opened.

支持プレート３２の前端における下面部分にステー３３が溶接固定されている。ステー３３は板状部材であって、ステー３３の長手方向は機体横方向に沿う。ステー３３の後端部は左右に亘って支持プレート３２の前端面部に溶接固定され、ステー３３の前端部は支持プレート３２の前端部よりも前側に位置する。ステー３３は支持プレート３２の下面部分に溶接される。このため、ステー３３は、支持プレート３２よりも支持プレート３２の厚み分だけ底面部２０ａから離間し、ステー３３と底面部２０ａとの間に隙間Ｓが形成されている。 A stay 33 is welded and fixed to the lower surface portion of the front end of the support plate 32. The stay 33 is a plate-like member, and the longitudinal direction of the stay 33 runs along the lateral direction of the fuselage. The rear end portion of the stay 33 is welded and fixed to the front end surface portion of the support plate 32 from left to right, and the front end portion of the stay 33 is located in front of the front end portion of the support plate 32. The stay 33 is welded to the lower surface portion of the support plate 32. Therefore, the stay 33 is spaced apart from the bottom part 20a by the thickness of the support plate 32, and a gap S is formed between the stay 33 and the bottom part 20a.

ステー３３の長手方向に沿って、三つの溶接ボルト３４，３４，３４がステー３３に溶接固定されている。溶接ボルト３４，３４，３４の頭部は隙間Ｓに位置し、溶接ボルト３４，３４，３４の頭部がステー３３の上面部分に溶接されている。 Three welding bolts 34, 34, 34 are welded and fixed to the stay 33 along the longitudinal direction of the stay 33. The heads of the welding bolts 34, 34, 34 are located in the gap S, and the heads of the welding bolts 34, 34, 34 are welded to the upper surface portion of the stay 33.

フランジ部３１ｆのうちの第一部材３１ａの前部に三つの貫通孔３１ｈ，３１ｈ，３１ｈが形成されている。第一部材３１ａの前端部は箱本体部３１の遊端部であって、箱本体部３１の遊端部がステー３３の位置する側へ揺動すると、貫通孔３１ｈ，３１ｈ，３１ｈに溶接ボルト３４，３４，３４が貫通する。この状態で溶接ボルト３４，３４，３４の夫々に蝶ナットＮｕ，Ｎｕ，Ｎｕが螺合して締め付けられることによって、箱本体部３１の遊端部がステー３３と蝶ナットＮｕ，Ｎｕ，Ｎｕとに挟まれる。これにより、箱本体部３１は揺動不能に位置保持され、この状態で箱本体部３１は開口部２０ｉから落下した石塊等を受け止め可能である。 Three through holes 31h, 31h, and 31h are formed in the front portion of the first member 31a of the flange portion 31f. The front end of the first member 31a is the free end of the box main body 31, and when the free end of the box main body 31 swings toward the side where the stay 33 is located, the welding bolts are inserted into the through holes 31h, 31h, 31h. 34, 34, 34 penetrate. In this state, the wing nuts Nu, Nu, Nu are screwed and tightened to the welding bolts 34, 34, 34, respectively, so that the free end of the box main body 31 is connected to the stay 33 and the wing nuts Nu, Nu, Nu. sandwiched between. Thereby, the box main body part 31 is held in position without being able to swing, and in this state, the box main body part 31 can receive a block of stone or the like that has fallen from the opening 20i.

箱本体部３１の貯留部分３１Ｂが満杯になると、作業者は蝶ナットＮｕ，Ｎｕ，Ｎｕを溶接ボルト３４，３４，３４から取り外し、箱本体部３１を下方向に揺動する。そして、箱本体部３１が揺動すると、貯留部分３１Ｂに溜まった石塊等が下方へ落下するため、箱状ケース部３０の内部の物が排出される。このため、箱状ケース部３０のメンテナンス作業が容易である。 When the storage portion 31B of the box body 31 becomes full, the operator removes the wing nuts Nu, Nu, Nu from the welding bolts 34, 34, 34, and swings the box body 31 downward. Then, when the box main body part 31 swings, the stone blocks and the like accumulated in the storage part 31B fall downward, so that the objects inside the box-like case part 30 are discharged. Therefore, maintenance work on the box-shaped case portion 30 is easy.

箱本体部３１の遊端部がステー３３に締結され、箱本体部３１の基端部が係合軸部３１Ｔ，３１Ｔに支持される。箱本体部３１のフランジ部３１ｆと支持プレート３２との間は、ステー３３の厚さの分だけ離間する。箱状ケース部３０のうち、フランジ部３１ｆの位置する領域は本発明の『取付部』である。換言すると、箱状ケース部３０に、板部材３５を箱本体部３１に取り付ける取付部が備えられ、取付部にフランジ部３１ｆが備えられている。取付部は、貯留可能状態において底面部２０ａとフランジ部３１ｆとに板部材３５を挟持させる。即ち、フランジ部３１ｆと支持プレート３２との間に板部材３５が設けられている。板部材３５の厚さと、ステー３３の厚さと、は同じまたは略同じである。また、取付部は箱本体部３１の上縁部に形成された開口部分である。 A free end portion of the box body portion 31 is fastened to the stay 33, and a base end portion of the box body portion 31 is supported by the engagement shaft portions 31T, 31T. The flange portion 31f of the box body portion 31 and the support plate 32 are spaced apart by the thickness of the stay 33. The region of the box-like case portion 30 where the flange portion 31f is located is the “attachment portion” of the present invention. In other words, the box-like case portion 30 is provided with an attachment portion for attaching the plate member 35 to the box body portion 31, and the attachment portion is provided with a flange portion 31f. The attachment portion allows the plate member 35 to be held between the bottom portion 20a and the flange portion 31f in the storage possible state. That is, a plate member 35 is provided between the flange portion 31f and the support plate 32. The thickness of the plate member 35 and the thickness of the stay 33 are the same or approximately the same. Further, the attachment portion is an opening formed at the upper edge of the box main body portion 31.

板部材３５は平坦面部３５Ａを有する。平坦面部３５Ａは四角形の形状に形成され、平坦面部３５Ａの四辺の夫々に折返部３５ａ，３５ｂ，３５ｃ，３５ｄが設けられている。折返部３５ａは平坦面部３５Ａの前縁部から下方へ垂下する。折返部３５ｂは平坦面部３５Ａの後縁部から下方へ垂下する。折返部３５ｃは平坦面部３５Ａの右縁部から下方へ垂下する。折返部３５ｄは平坦面部３５Ａの左縁部から下方へ垂下する。折返部３５ａ，３５ｂ，３５ｃ，３５ｄの夫々は、平坦面部３５Ａの平坦面に対して直交または略直交するように下方へ垂下する。このように、板部材３５に、平面状の平坦面部３５Ａと、平坦面部３５Ａの外周部において平坦面部３５Ａに対して折れ曲がるとともに箱本体部３１の開口部分に係止可能な複数の折返部３５ａ，３５ｂ，３５ｃ，３５ｄ（本発明に係る「嵌合部」に相当）と、が形成されている。 The plate member 35 has a flat surface portion 35A. The flat surface portion 35A is formed in a rectangular shape, and folded portions 35a, 35b, 35c, and 35d are provided on each of the four sides of the flat surface portion 35A. The folded portion 35a hangs downward from the front edge of the flat surface portion 35A. The folded portion 35b hangs downward from the rear edge of the flat surface portion 35A. The folded portion 35c hangs downward from the right edge of the flat surface portion 35A. The folded portion 35d hangs downward from the left edge of the flat surface portion 35A. Each of the folded portions 35a, 35b, 35c, and 35d hangs downward so as to be perpendicular or substantially perpendicular to the flat surface of the flat surface portion 35A. In this way, the plate member 35 includes a planar flat surface portion 35A, and a plurality of folded portions 35a that can be bent with respect to the flat surface portion 35A at the outer peripheral portion of the flat surface portion 35A and can be locked to the opening portion of the box body portion 31. 35b, 35c, and 35d (corresponding to the "fitting part" according to the present invention) are formed.

第一部材３１ａの前部のフランジ部３１ｆにおける貫通孔３１ｈ，３１ｈ，３１ｈよりも後側の領域に、機体横方向に延びる長孔３１ｋが形成されている。長孔３１ｋは本発明の『取付部』の一部である。長孔３１ｋの機体横方向の長さは、折返部３５ａの左右方向の長さよりも長く形成され、折返部３５ａの左右両端が長孔３１ｋの範囲内に位置する。これにより、折返部３５ａが長孔３１ｋを貫通する。箱本体部３１の遊端部がステー３３に締結された状態で、折返部３５ａ及び長孔３１ｋはステー３３よりも後側（箱本体部３１の揺動基端部の位置する側）に位置する。 A long hole 31k extending in the lateral direction of the body is formed in a region of the flange portion 31f at the front of the first member 31a on the rear side of the through holes 31h, 31h, 31h. The elongated hole 31k is a part of the "attachment part" of the present invention. The length of the elongated hole 31k in the lateral direction of the body is longer than the length of the folded portion 35a in the left-right direction, and both left and right ends of the folded portion 35a are located within the range of the elongated hole 31k. As a result, the folded portion 35a passes through the elongated hole 31k. When the free end of the box body 31 is fastened to the stay 33, the folded part 35a and the long hole 31k are located on the rear side of the stay 33 (the side where the swing base end of the box body 31 is located). do.

折返部３５ｂは、第一部材３１ａの後部のフランジ部３１ｆに引っ掛けられる。折返部３５ｃは、右側の第二部材３１ｂのフランジ部３１ｆに引っ掛けられる。折返部３５ｄは、左側の第二部材３１ｂのフランジ部３１ｆに引っ掛けられる。このように、板部材３５は箱本体部３１に着脱可能に構成されている。即ち、複数の折返部３５ａ，３５ｂ，３５ｃ，３５ｄが当該開口部分に係止されると、箱本体部３１の開口部分は、板部材３５のうちの折返部３５ａ，３５ｂ，３５ｃ，３５ｄよりも平坦面部３５Ａの位置する側の領域に嵌まり込む。 The folded portion 35b is hooked onto the rear flange portion 31f of the first member 31a. The folded portion 35c is hooked onto the flange portion 31f of the second member 31b on the right side. The folded portion 35d is hooked onto the flange portion 31f of the second member 31b on the left side. In this way, the plate member 35 is configured to be detachable from the box body portion 31. That is, when the plurality of folded parts 35a, 35b, 35c, and 35d are locked in the opening part, the opening part of the box body part 31 is larger than the folded parts 35a, 35b, 35c, and 35d of the plate member 35. It fits into the region on the side where the flat surface portion 35A is located.

平坦面部３５Ａの中央領域に開口部３５ｈが形成されている。開口部３５ｈの形状及び大きさと、開口部２０ｉの形状及び大きさと、は同じまたは略同じとなるように、板部材３５の開口部３５ｈは形成されている。開口部３５ｈは本発明の『第二開口部』であって、開口部３５ｈは貯留可能状態において開口部２０ｉと重複する。折返部３５ａ，３５ｂ，３５ｃ，３５ｄの夫々が箱本体部３１に引っ掛けられた状態で、箱本体部３１の遊端部がステー３３に締結されると、開口部２０ｉと開口部３５ｈとは重複または略重複する。これにより、開口部２０ｉから落下した石塊等が、箱本体部３１のフランジ部３１ｆと支持プレート３２との間に入り込むことなく、箱本体部３１の貯留部分３１Ｂに案内される。 An opening 35h is formed in the central region of the flat surface portion 35A. The opening 35h of the plate member 35 is formed so that the shape and size of the opening 35h and the shape and size of the opening 20i are the same or substantially the same. The opening 35h is the "second opening" of the present invention, and the opening 35h overlaps the opening 20i in the storage possible state. When the free end of the box main body 31 is fastened to the stay 33 with each of the folded parts 35a, 35b, 35c, and 35d hooked on the box main body 31, the opening 20i and the opening 35h overlap. or almost duplicate. As a result, the stone blocks and the like that have fallen from the opening 20i are guided to the storage portion 31B of the box main body 31 without entering between the flange 31f of the box main body 31 and the support plate 32.

作物の種類によっては、搬送ケース２０の中で搬送される収穫物に石塊等が含まれないために、箱本体部３１が必要ない場合も考えられる。このため、本実施形態では、図８及び図９に示されるように、箱本体部３１に対して着脱可能な板部材３６が備えられ、板部材３６は、板部材３５に代えてフランジ部３１ｆと支持プレート３２との間に配置可能である。板部材３６は、開口部２０ｉから箱本体部３１に収穫物等が落下しないように、開口部２０ｉを閉塞する。 Depending on the type of crop, the box main body 31 may not be necessary because the crop to be conveyed in the conveyance case 20 does not contain stones or the like. For this reason, in this embodiment, as shown in FIGS. 8 and 9, a plate member 36 is provided that is detachable from the box main body 31, and the plate member 36 replaces the plate member 35 with the flange portion 31f. and the support plate 32.

板部材３６は平坦面部３６Ａを有する。平坦面部３６Ａは四角形の形状に形成され、平坦面部３６Ａの四辺の夫々に折返部３６ａ，３６ｂ，３６ｃ，３６ｄが設けられている。折返部３６ａ，３６ｂ，３６ｃ，３６ｄの夫々は平坦面部３６Ａにおける縁部から下方へ垂下する。折返部３５ａが長孔３１ｋを貫通し、折返部３６ｂが係合軸部３１Ｔに引っ掛けられ、折返部３５ｃ，３５ｄが左右のフランジ部３１ｆ，３１ｆに引っ掛けられる。このように、折返部３６ａ，３６ｂ，３６ｃ，３６ｄの夫々の構成は、上述した折返部３５ａ，３５ｂ，３５ｃ，３５ｄの構成と同じである。即ち、複数の折返部３６ａ，３６ｂ，３６ｃ，３６ｄが当該開口部分に係止されると、箱本体部３１の開口部分は、板部材３６のうちの折返部３６ａ，３６ｂ，３６ｃ，３６ｄよりも平坦面部３６Ａの位置する側の領域に嵌まり込む。 The plate member 36 has a flat surface portion 36A. The flat surface portion 36A is formed in a rectangular shape, and folded portions 36a, 36b, 36c, and 36d are provided on each of the four sides of the flat surface portion 36A. Each of the folded portions 36a, 36b, 36c, and 36d hangs downward from the edge of the flat surface portion 36A. The folded portion 35a passes through the elongated hole 31k, the folded portion 36b is hooked on the engagement shaft portion 31T, and the folded portions 35c and 35d are hooked on the left and right flanges 31f and 31f. In this way, the respective configurations of the folded portions 36a, 36b, 36c, and 36d are the same as the configurations of the folded portions 35a, 35b, 35c, and 35d described above. That is, when the plurality of folded parts 36a, 36b, 36c, and 36d are locked in the opening part, the opening part of the box body part 31 is larger than the folded parts 36a, 36b, 36c, and 36d of the plate member 36. It fits into the area on the side where the flat surface portion 36A is located.

平坦面部３６Ａに、平板状の付加板部３６Ｂが取り付けられている。平坦面部３６Ａに複数の孔部３６ｈが形成され、付加板部３６Ｂは複数の孔部３６ｈで溶接固定されている。これにより、付加板部３６Ｂが平坦面部３６Ａに支持される。付加板部３６Ｂの外周形状は開口部２０ｉの外周形状と同じまたは略同じである。折返部３６ａ，３６ｂ，３６ｃ，３６ｄの夫々が箱本体部３１に引っ掛けられた状態で、箱本体部３１の遊端部がステー３３に締結されると、付加板部３６Ｂが開口部２０ｉの全域を閉塞する。付加板部３６Ｂは本発明の『閉塞部』であって、付加板部３６Ｂは貯留可能状態において開口部２０ｉを閉塞する。付加板部３６Ｂの厚さと、底面部２０ａと支持プレート３２とを併せた厚さと、は同じまたは略同じである。このため、開口部２０ｉが付加板部３６Ｂによって閉塞されると、付加板部３６Ｂの上面部分と、底面部２０ａの上面部分と、が面一となる。これにより、搬送ケース２０の中で搬送される収穫物が、開口部２０ｉに引っ掛かり難くなって円滑に搬送される。 A flat additional plate portion 36B is attached to the flat surface portion 36A. A plurality of holes 36h are formed in the flat surface portion 36A, and the additional plate portion 36B is fixed by welding through the plurality of holes 36h. Thereby, the additional plate portion 36B is supported by the flat surface portion 36A. The outer circumferential shape of the additional plate portion 36B is the same or substantially the same as the outer circumferential shape of the opening 20i. When the free end portion of the box body portion 31 is fastened to the stay 33 with each of the folded portions 36a, 36b, 36c, and 36d hooked on the box body portion 31, the additional plate portion 36B covers the entire area of the opening portion 20i. occlude. The additional plate part 36B is a "closing part" of the present invention, and the additional plate part 36B closes the opening 20i in the storage possible state. The thickness of the additional plate portion 36B and the combined thickness of the bottom surface portion 20a and the support plate 32 are the same or approximately the same. Therefore, when the opening 20i is closed by the additional plate part 36B, the upper surface part of the additional plate part 36B and the upper surface part of the bottom part 20a become flush with each other. As a result, the harvested products transported in the transport case 20 are less likely to be caught in the opening 20i and are transported smoothly.
