Abstract

PROBLEM TO BE SOLVED: To improve handling of a container bag for receiving crops by providing a plurality of locking members for keeping the bag opened on an internal side of a throw-in port of the container bag for receiving crops and at a border between a lid and a body. SOLUTION: A root crop gathering machine comprising a mechanism for cutting leaves and a mechanism for storing roots in a container feeds gathered root crops from a feed terminal end of a selection conveyer to a root crop housing, which comprises a container bag 33 for receiving the root crops, a bag receive and a crane for hanging up the container bag 33. In the container bag 33, a plurality of ring-like locking members 58 are provided on an internal side of a throw-in port 57 at a border between a lid 33a and a housing body 33b, while a belt member 59 for transportation is provided on an external side of the bag 33. The belt member 59 fixes an endless intermediate part to opposite sides and to a bottom approximately in parallel, while both semicircular ends protruding from the lid 33a are formed on a first locking part 59a, and a ring- like second locking part 59b is formed at a corner between the side and the bottom.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root vegetable harvesting machine for harvesting vegetables such as carrots, and stores the harvested vegetables such as carrots in a storage bag held in the harvesting machine until a predetermined amount is reached. It is a storage bag for crops.

[0002]

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 inlet of the bag. However, when the crop is full, the lid that is bent outward is folded back inward to close the inlet and seal the bag.

However, when the locking member is provided on the outside of the bag as described above, it is difficult to sufficiently secure the charging port because the locking member becomes an obstacle when the lid is bent outwardly when forming the charging port. Not only that, but when the crop is stored, the lid part is folded inside, and if you try to cover it, it will be embedded in the crop and it will not be easy to take it out, making it difficult to seal the input port. I was letting it. Also, when a full storage bag is hung by a crane or the like that is installed in a harvester and unloaded on the ground, etc., a catching accident of the locking member may occur, so careful handling is required. there were.

[0004]

Therefore, according to the present invention, a plurality of locking members for holding an opening of a bag are provided at the boundary position between the lid and the main body on the inner surface side of the input port of the bag for storing crops. The lid of the storage bag is bent sufficiently outward to ensure that the lid is held in the open position to maximize the size of the input port and promote good storage of crops without involving the lid. Let
In addition, the folding of the lid at the time of opening and the double wall structure of the bag main body make it possible to form a highly rigid rim without slack, and the storage bag can be loaded and unloaded with the lid closed. In the case of carrying and carrying work, it is possible to carry out a good handling work without causing an obstacle by putting the locking member in the bag.
