本考案は、コンバイン等に搭載されるグレンタ
ンクの底板開閉構造に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bottom plate opening/closing structure of a grain tank mounted on a combine harvester or the like.
通常、コンバイン等に搭載されるグレンタンク
は、刈取る作物に応じて種々の穀粒を貯留するこ
ととなるため、一つの種類の作物の刈取りを完了

ない。
Normally, grain tanks installed on combines etc. store various grains depending on the crop to be harvested, so when one type of crop is harvested and before another type of crop is harvested. First, it is necessary to completely eliminate the grains of the first type that remain in the gret tank to prevent them from being mixed with the grains of the crops that will be harvested later.
従来、これに対処するためにグレンタンクの底

締め固定することによつて開閉可能にし、必要な
時はボルトを抜いて底板を揺動開放し、タンク内
に残る穀粒を掃除できるように構成してあつた。 Conventionally, in order to deal with this, the bottom plate of the grain tank was made to be able to swing open and close around an axis parallel to the bottom screw, and its free end was bolted and fixed to the tank body, making it possible to open and close it. When necessary, the tank was designed so that the bottom plate could be swung open by removing the bolts to clean out any remaining grains in the tank.

However, with the above configuration, since the bottom plate of the grain tank is generally long, bolts must be tightened at multiple locations, making it difficult to align the bolt insertion holes, and the bolt tightening process is difficult. There were some inconveniences in handling such as time-consuming process, and the results were not satisfactory.
本考案は、このような実情に着目し、簡単な改

The characteristic configuration of the present invention, which has been made to achieve the above object, is that the bottom plate of the grain tank can be opened by swinging downward around an axis parallel to the bottom screw, and the bottom plate can be opened at multiple locations on the free end of the bottom plate. A connecting pin is provided at one of the multiple locations on the corresponding grain tank side, and an engaging portion that engages with the connecting pin is provided at the other, and the multiple connecting pins are connected by a connecting rod, and their functions and effects. is as follows.
つまり、連結杆を所定通りに操作すると複数の

In other words, when the connecting rod is operated as specified, multiple connecting pins are engaged and disengaged from the engaging portion at once, the connection between the free end of the bottom plate and the grain tank is released, and the bottom plate is moved downward around the axis parallel to the bottom screw. The bottom of the grain tank is released. Moreover, when the bottom plate is swung upward to open the bottom of the grain tank, the positioning of the connecting pin and the engaging portion is inevitably performed, and the engagement between them can be easily performed.
従つて本考案によれば、ボルト稈通孔の位置決

ある。 The connecting pin 12 is supported through the pin holder 13, and the spring 1 is interposed between the protruding edge 12a of the connecting pin 12 and the pin holder 13.
4, it is elastically biased toward the engagement side, that is, toward the inside of the body. Then, the head sides of the three connecting pins 12 are connected by the connecting rod 15, and by pulling the connecting rod 15 outward at an arbitrary point, the three connecting pins 1
2 come out of the boss 10b at the same time, and the engagement is released. When the engagement is released, the bottom plate 1
0 swings downward due to its own weight, and the bottom of the grain tank 5 is opened. In addition, a guide surface 10c is formed on the bottom plate 10, and when the bottom plate 10 is pivoted upward to close the bottom of the grain tank 5, the guide surface 10c presses the tip side of the connecting pin 12, so that the bottom plate 10 is prevented from being damaged by the protrusion of the connecting pin 12, and the connecting pin 12 is engaged with the boss 10b by the spring 14 when the bottom plate 10 is completely closed, so to speak, an automatic locking mechanism is provided. I'm set up to work.
