るという問題がある。 In the conventional device mentioned above, the bottom plate and the rear wall member are linked by levers and connecting rods, and the operating lever opens and closes them at the same time. However, because the opening speed of the rear wall member and the bottom plate is slow, beans begin to fall due to their own weight. There is a problem in that the culms hit the rear wall member/bottom plate, break the bundle, and fall in a scattered manner.

本考案は、上記の問題点に鑑み後壁部材の開き
を迅速にすることを目的とする。 The present invention aims to speed up the opening of the rear wall member in view of the above problems.

のように開く。 With the hopper H in Figure 1 closed, when the operating rod 7 is pushed manually or powered to the right in the direction of the arrow O, the T-shaped lever 5 rotates clockwise about the shaft 6 to pull the rear wall member. Pull down the upper connecting rod 8 and release the lever 12.
is rotated counterclockwise around the fulcrum 11, and the rear wall member 2 is pulled up along the locus 1 of the connection point 14 from the position 2A shown by the dashed line in FIG. 3 via the connection point 14. At this time, the opening/closing link 13 located above the lever 12 pulls up the rear wall member 2 via the connecting point 15 and following its trajectory 2 around the connecting point 16. Therefore, the lower end of the rear wall member 2 opens quickly and largely as shown in FIG.

This is a conveyor belt that conveys the bean culms to one side and above the hopper H and guides them to the hopper H via a guide 25. The lower part opens into a substantially V-shape in plan, and a short conveyor belt 26 is placed along each inner side 24a of the lower part, and the upper conveyor belt 2
4, 24. 28 is an engine, and 29 is a control handle.

なお、本考案の収納ホツパは、豆刈機だけでな
く、他の収穫機にも適用されるものである。 Note that the storage hopper of the present invention is applicable not only to bean cutters but also to other harvesting machines.

る。C. Effects of the invention In the present invention, when a lifting action is applied to the rear wall member 2 of the hopper via the lever 12, the lifting link 13 acts in conjunction with the lifting action, and the rear wall member is pulled up. The problem of the rear wall member 2 rapidly opening due to the combination of the two movements and colliding with the accumulated bean culm bundle and breaking the bundle is well solved.

また後壁部材が後方に大きく突出することがな
いので、豆刈機は小回りが利くようになつて操縦
性が向上する効果がある。 Furthermore, since the rear wall member does not protrude rearward to a large extent, the bean cutter becomes able to turn in a small radius and has the effect of improving maneuverability.
