Description

[Detailed Description of the Invention] The present invention relates to a grain storage device in a grain harvesting machine such as a combine harvester or a Vesta.

Conventionally, a grain guide tube provided below the hopper has been formed of a flexible member made of a different material from the hopper in order to prevent the grain guide tube from getting in the way when attaching and removing the storage bag.

In this type of device, a horizontal bridge plate is interposed between the hopper and the grain guide tube, and the bridge plate fixedly supports the hopper and the grain guide tube, and the bridge plate and the grain guide tube are fixedly supported. The hopper is opened and closed by sliding the opening/closing plate horizontally.

In such a case, fixing members such as bolts that fix the grain guide cylinder and members such as stoppers that restrict the movement of the opening/closing plate protrude from the bottom of the bridge plate, and these members are used to attach and detach the storage bag. Sometimes they get caught in the storage bag, hindering the attachment/detachment operation, and the storage bag bursts, causing grains to scatter.
Sometimes it happened.

In addition, since the opening/closing plate slides on the upper surface of the seed plate, the bridge plate must be made wide and at the same time long in the sliding direction, which tends to cause distortion, which is unacceptable and reduces the processing yield. However, there were drawbacks such as the opening/closing plate not being able to move smoothly.

The present invention was devised to eliminate the above-mentioned drawbacks, and the side walls are formed by vertically extending both side edges of the bridge board in the direction orthogonal to the moving direction of the opening/closing board, and the side walls are The upper side wall of the hopper is fixed to the hopper, and the lower edge of the side wall body is positioned lower than the fixing member that fixes the grain guide tube to the bridge plate, the stopper of the opening/closing plate, etc. that protrudes downward from the bottom surface of the seed root. By doing so, the bridge plate is formed into a substantially H-shape by the side walls on both sides, so it is not only reinforced and prevents the occurrence of distortion, but also the lower end of the side wall located below the members such as the fixing members. To provide a grain storage device in which the edge serves as a guide for the storage bag and the operation of attaching and removing the storage bag can be smoothly performed without the storage bag being caught on a fixing member or the like.

The structure of the present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 denotes a hopper, and the hopper 1 is connected to a grain conveying tube (not shown) extending from a threshing section of a combine harvester. It is used to temporarily store the grains being transported.

Reference numeral 2 denotes a storage bag holder, and the storage bag holder 2 is disposed horizontally below the hopper 1.

Reference numeral 3 denotes a pair of left and right bag hanging support arms erected at the rear of the machine. It supports the storage bags in an expanded state, and a required number of storage bags can be hung behind it.

Reference numeral 4 denotes a bridge plate having a gutter 4a formed therein, and the bridge plate 4 is horizontally fixed to the fuselage by an appropriate method such as bolts.

Reference numeral 5 denotes a side wall body, which is vertically provided at both ends of the bridge board 4 in the longitudinal direction, and includes an upper side wall 6 above the bridge board 4 and a lower part below the bridge board 4. and the side wall 8, and the whole has a substantially H-shape.

The lower end of the hopper 1 is fixed to the opposing space 6a formed by the upper side wall 6 with a connecting member 6b, and an opening/closing plate 7 is mounted on the bottom 6c, slightly touching the lower end of the gutter 1a of the hopper 1. It is slidably attached with a gap.

7a is a grain inlet provided in the opening/closing plate T.

On the other hand, a concave space 8a with an open bottom is formed in a portion of the lower side wall 8 corresponding to the gutter 4a.

In this space 8a, there is a gutter 4a and a grain drop hole 4b formed inside the gutter 4a through the partition wall 4a'.
A fixing member 11 of a flexible grain guide tube 10 made of an elastic body and extending downwardly surrounding the lower edge 8 of the lower side wall 8
It is stored and installed so that it does not protrude below b.

Reference numeral 9 denotes a stopper of the opening/closing plate 7 formed into a mountain shape by an elastic body 9a, and the stopper 9 is connected to the grain guide cylinder 10.
Similarly to the fixing member 11, it is stored in a storage part 4b formed in the bridge plate 4 so as not to protrude downward from the lower edge 8b of the lower side wall 8, and engages with the engagement hole γa provided in the opening/closing plate T. At the same time, the amount of movement of the opening/closing plate T is regulated, and wasteful movement due to vibration or shaking of the aircraft body is regulated.

9c is an opening formed below the stopper storage portion 4d, and the opening 9c allows the elastic body 9a to be connected to the opening/closing plate I.
The opening/closing board 7 operation can be maintained in a stable state at all times.

The button 4c in the figure is an auxiliary grain drop hole bored in the bridge plate 4, located in the closing direction of the opening/closing plate T and near the grain drop hole 4b.

In the configuration as described above, 1. When performing harvesting work with a combine harvester, insert the required number of storage bags into the left and right pair of tear support arms 3 in advance, and then pull out the storage bag on the front side to expand it. Open it and insert the grain guide cylinder 10.

Next, the combine harvester is operated to perform a series of harvest operations such as reaping and threshing, and the grains are stored in the storage bag.

During harvesting, if it is confirmed by a grain fullness sensing device (not shown) that the storage bag is full of grains, the opening/closing plate 1 is pushed in the closing direction to close the gutter 4a. After making sure that the grains do not flow into the storage bag, replace the storage bag, insert the opening of the new storage bag into the grain guide cylinder 10, and pull back the opening/closing plate 7, and then the grains can be placed in the storage bag again. can be made to flow into the

In this way, if the storage bag becomes full during harvesting,
Although the storage bag must be replaced, in the present invention, the fixing member 11 that fixes the grain guide cylinder 10 to the bridge plate 4 is attached to the side wall body 5 that is vertically disposed at both ends of the bridge plate 4 in the longitudinal direction. It is housed in a downward concave space 8a formed in the lower side wall 8 so as not to protrude downward from the lower edge 8b of the lower side wall 8, and restricts the amount of movement of the opening/closing plate 7. Like the fixing member 11, the stopper 9 is also mounted so as not to protrude downward from the lower end edge 8b of the lower side wall 8, so that the storage bag is placed under the stopper when the storage bag is attached or removed. 9 or the fixing member 11, which would obstruct the attaching/detaching operation, the lower edge 8b serves as a guide, making it possible to attach and detach the storage bag extremely easily.

In addition, since the bridge plate 4 is reinforced by the side walls 5 in a substantially H-shape, the rigidity of the bridge plate 4 is improved, distortion during processing is reduced, and processing yield is improved. Since the upper side wall 6 is fixed to the hopper 1, the bridge plate 4 is further reinforced, preventing distortion due to external pressure and smooth operation of the opening/closing plate. Since the lower part of 4d is open, any dirt that has entered the core can be quickly discharged to the outside of the machine, so the operation of the opening/closing plate 7 can always be maintained in a smooth and stable state. .

In short, the present invention provides a horizontal bridge plate between a hopper and a grain guide cylinder that are configured separately, and an opening/closing plate is provided in a gap between the top surface of the bridge plate and the hopper. In the grain storage device, the side edges of the bridge plate in the direction orthogonal to the moving direction of the opening/closing plate are extended vertically to form a side wall body, and the upper part of the side wall body is In addition to fixing the side wall to the hopper, the lower edge of the side wall body is positioned lower than the fixing member for fixing the grain guide cylinder to the bridge board, the stopper of the opening/closing board, and other members that protrude downward from the bottom of the bridge board. , the fence plate on which the opening/closing plate slides is reinforced in a roughly H-shape by upper and lower side walls provided on both side edges, which reduces distortion during molding and increases processing yield. Moreover, when the hopper and the grain guide tube are interposed and fixed, the upper wall of the side wall body is fixed to the hopper, so the fence plate is compatible with the side wall plate. This further strengthens the reinforcement, prevents distortion and deformation due to external pressure, allows the horizontal state to be maintained, and enables smooth movement of the opening/closing plate.

Furthermore, since the lower edge of the side wall body is located lower than the fixing members and other members that protrude downward from the bottom of the bridge board, the lower edge of the side wall body acts as a guide when attaching and detaching the storage bag. This prevents the storage bag from getting caught on protruding members such as fixing members, and allows the storage bag to be attached and removed without being bothered by these protruding members.
