Description

【０００１】
【発明の属する技術分野】
本発明は、例えばニンジンなどの野菜を収穫する根菜収穫機にあって、該収穫機に保持する収納袋に収穫されたニンジンなど野菜を所定量となるまで収納するようにした作物用収納袋である。
【０００２】
【発明が解決しようとする課題】
従来、布袋など可撓性に形成される収納袋にあって、収納袋を保持する係止部材は、該袋の上部投入口近傍の袋外側面に設けられていて、作物の満杯時には外側に折曲げられた蓋部を、内側に折り返して投入口を塞いで袋の密封を行っている。
【０００３】
しかし乍ら、このように係止部材を袋外側に設けた場合、投入口形成における蓋部の外側折曲げ時に係止部材が邪魔となって、投入口の充分な確保が困難となるばかりでなく、作物収納時蓋部が内側に折り込まれ、蓋をしようとした場合には作物内に埋め込まれた状態となってその取出しも容易でなく投入口の密封作業を困難なものとさせていた。
また、満杯収納袋を収穫機に装備するクレーンなどによって、吊下げ地上などに積降ろしする場合に、係止部材の引掛り事故を発生させるなどして、その取扱い作業において慎重さが要求されるものであった。
【０００４】
【課題を解決するための手段】
本発明は、作物を収納する平面４角立方形の可撓性の収納袋（３３）を設け、該収納袋（３３）は、上部の蓋部（３３ａ）と、下部の本体部（３３ｂ）との境界位置を投入口（５７）とし、該投入口（５７）の内面側で、該蓋部（３３ａ）と収納本体部（３３ｂ）との境界位置の４角に、輪状の係止部材（５８）を４点に設け、袋受台（３４）上において、中間にバネ（５２）を介設するワイヤ（５３）で、前記係止部材（５８）を吊上げる状態で、該収納袋（３３）を弾性を有する状態で４点支持し開口保持するものである。
即ち、作物を収納する収納袋の投入口の内面側で蓋部と本体部の境界位置に、該袋を開口保持する複数の係止部材を設けて、収納袋の蓋部を充分に外側に折曲げて確実に蓋部を開放位置に保持して投入口を最大に大きく形成して、蓋部を巻き込むことのない作物の良好な収納を助長させ、また開口時の蓋部の折曲りと袋本体部との二重壁構造によって弛みのない高剛性の口縁部の形成を可能とさせると共に、蓋部を閉封しての収納袋の積降ろしや運搬作業においては、係止部材を袋内に納めて障害とさせることなどない良好な取扱い作業を可能とさせるものである。

BACKGROUND OF THE INVENTION
The present invention relates to a crop storage bag for harvesting vegetables such as carrots and the like, and storing the harvested carrots and other vegetables in a storage bag held in the harvester until a predetermined amount is obtained. is there.
[0002]
[Problems to be solved by the invention]
Conventionally, in a flexible storage bag such as a cloth bag, a locking member for holding the storage bag is provided on the outer surface of the bag near the upper charging port of the bag, and is outside when the crop is full. The folded lid is folded inward to close the inlet and seal the bag.
[0003]
However, when the locking member is provided on the outside of the bag in this way, the locking member becomes an obstacle when the lid part is bent outside in forming the charging port, and it becomes difficult to sufficiently secure the charging port. When the crop was stored, the lid was folded inward, and when trying to cover it, it was embedded in the crop and it was not easy to take out, making it difficult to seal the inlet .
In addition, when loading and unloading a full storage bag on a suspended ground with a crane equipped with a harvesting machine, etc., it is necessary to be careful in handling such as causing a catching accident of the locking member. It was a thing.
[0004]
[Means for Solving the Problems]
The present invention provides a flat rectangular cubic flexible storage bag (33) for storing crops, and the storage bag (33) includes an upper lid portion (33a) and a lower body portion (33b). The boundary position between the lid portion (33a) and the storage main body portion (33b) on the inner surface side of the insertion port (57) is a ring-shaped locking member. (58) is provided at four points, and on the bag receiving base (34), in the state where the locking member (58) is lifted by a wire (53) having a spring (52) interposed therebetween, the storage bag (33) is supported by four points in an elastic state and held open .
In other words , a plurality of locking members for opening and holding the bag are provided at the boundary position between the lid and the main body on the inner surface side of the inlet of the storage bag for storing crops, and the lid of the storage bag is sufficiently outside. Bends securely to hold the lid in the open position, forming the largest entry port to facilitate good storage of crops that do not involve the lid, and bending the lid when opened The double-wall structure with the bag body enables the formation of a highly rigid mouth edge without sagging, and the locking member is used for loading and unloading and transporting the storage bag with the lid closed. It is possible to perform a good handling operation without being disturbed by being placed in a bag.

The endless intermediate portion is fixed substantially parallel to the opposite side and bottom of the cubic bag (33), and the semicircular ends protruding from the opposite lid (33a) are the first locking portions (59a). In addition, a ring-shaped second locking portion (59b) is formed at the corner portions of the side surface and the bottom surface, and usually the mounting hook (40) of the conveyor (32) and the column (51) on the hook receiving base (34). In addition, the bag (33) is opened so that the locking member (58) is lifted by the wire (52) having the spring (52). And held, it is provided to perform the storage of carrot (A) to be harvested.
[0018]
On the other hand, when the carrot (A) as a crop is full in the bag (33), the hook (50) of the crane (35) is engaged with the first locking portion (59a), and the bag (33). The closing port (57) is closed with the lid (33a) or transported to the field with the lid open (33a), and when the carrot (A) in the bag (33) is taken out, the second locking portion (59b ) And the hook (50) of the crane (35) are engaged with each other, and the bag (33) is turned upside down when the crane (35) is lifted, thereby enabling easy removal in a short time.
[0019]
Further, in this case, the strength of the bag (33) is improved by fixing the opposing side surface and bottom surface of the belt member (59) and the bag (33), and the lid (33a) and the first locking when the insertion port (57) is opened. The rigidity of the bag mouth edge is improved by a double wall structure such as folding of the portion (59a), and the three suture threads (60) of the locking member (58), the bag (33) and the belt member (59). The joint strength between the locking member (58) and the bag (33) is improved by integral fixing using the above. The hook (50) of the crane (35) may be directly engaged with the locking member (58) and lifted.
[0020]
In FIG. 7, a part of the storage bag (33) is opened, a reinforcing metal fitting (61) is attached, and a band member (59) is provided on the inner surface side of the bag (33) from the metal fitting (61). ) Projecting partly to form a ring-shaped locking portion (59c) to be a locking member (58) such as a hook (50) or a wire (52) that replaces the locking member (58). It is provided.
[0021]
In FIG. 8, the above-mentioned locking member (58) is further attached to the locking portion (59c), so that the locking member (58) can be freely mounted and the hook (50) is engaged. This is provided for the sake of simplicity.

【The invention's effect】
As is apparent from the above embodiments, the present invention provides a flat square cubic flexible storage bag (33) for storing crops, and the storage bag (33) includes an upper lid (33a) and The boundary position with the lower body portion (33b) is defined as the insertion port (57), and the boundary position between the lid portion (33a) and the storage body portion (33b) is 4 on the inner surface side of the insertion port (57). At the corners, ring-shaped locking members (58) are provided at four points, and on the bag receiving base (34), the locking member (58) is attached by a wire (53) having an intermediate spring (52). Since the storage bag (33) is elastically supported at four points and held open while being lifted, the lid (33a) of the storage bag (33) is sufficiently folded outward to ensure the lid. The opening (57) can be formed in the largest size by holding the portion (33a) in the open position, and the lid (33a) can be prevented from being caught. Ensuring good storage of crops, and securing a highly rigid lip with no slack by folding the lid (33a) when opened and the double wall structure of the bag body (33b) In the loading and unloading and transporting operations of the storage bag (33) with the lid (33a) closed, the locking member (58) is placed in the bag (33) to prevent trouble. It is possible to achieve a remarkable effect such that it is possible to perform a good handling operation that is not performed.
