【発明の属する技術分野】
本発明は、走行車の荷台に載置して穀物を搬送する穀粒ホッパの機枠寸法をコンパクトに且つ収容量を増やし、搬送効率を向上させる構成に関する。
【0002】
【従来の技術】
従来の技術として、走行車の荷台に載置され、後面視V字状に底面傾斜板を形成し、この底面傾斜板の傾斜下降端部に回動支点を設け、傾斜上昇端部をホッパの側面板に当接させ摺動するよう起伏回動自在とした穀粒ホッパにおいて、この底面傾斜板にコイルバネの一端を係止具を介して連結し、穀粒ホッパの上部には前記係止具の上方位置に吊下枠を設け、この吊下枠に前記コイルバネの他端を連結し、これらコイルバネの周囲にバネカバーを設けた構成は公知である。(特許文献1)

【0004】
【発明が解決しようとする課題】
上記従来技術によれば、穀粒ホッパ内にコイルバネを吊設するため穀粒排出時に穀粒の流動を阻害するという問題がある。又、穀粒貯留時にはコイルバネがバネカバーよりはみ出し、このはみ出したコイルバネの周囲に達する穀粒がコイルバネを適正に作動させないという問題がある。
【0005】
そして、穀粒の排出と同期して縮むコイルバネと、このコイルバネに連結され穀粒の排出と同期して上昇回動する底面傾斜板に穀粒が挟まり穀粒を傷つけることがある。又、前記コイルバネは穀粒ホッパ上方に配置した吊下枠に吊り下げるよう設けられるので機体全高が高くなるという問題がある。
【0006】
そこで本発明は、機体をコンパクトに構成するとともに、ホッパ内の収容量の向上を計るとともに穀物貯留時の重心を低くし、さらに、穀粒排出効率を向上させた穀粒ホッパを提供することを目的とする。
【0007】
【課題を解決するための手段】
上記課題を解決するために、直方体形状に枠組みした機枠体の内側側面四方を側面板にて囲み、底部には後面視略V字状とした底面傾斜板を対称に設け、この底面傾斜板は傾斜下降端部に回動支点を設け起伏回動自在とするとともに傾斜上昇端部を前記側面板に当接し摺動自在となるよう構成され、この底面傾斜板のV字状谷部に排出搬送体を設けてなる穀粒ホッパにおいて、前記底面傾斜板を上方に付勢するよう圧縮弾性体を設け、ホッパ内に穀粒が貯留されると底面傾斜板は下降回動し、下降回動と同時に前記圧縮弾性体は圧縮してホッパの収容量を増加させ、貯留された穀粒が排出搬送体にて排出されると前記圧縮弾性体は徐々に伸張し底面傾斜板は上昇回動させ穀粒の排出を補助するよう構成したことにより、機体をコンパクトに構成し、且つ収容容積を増すことができ、さらに穀物貯留時の重心を低くすることができ運搬時の走行バランスを良好とする。さらに、圧縮弾性体にて底面傾斜板を上方に付勢することで穀粒の排出を補助し排出効率が向上する。
【0008】
又、圧縮弾性体には、高圧ガスを封入したガススプリングを用いたことにより、簡単な構成で部品点数を減らすことができコストダウンすることができる。
【0009】
又、起伏回動自在とした底面傾斜板とこの底面傾斜板が当接する側面板の摺動部には、側面板内側より下方に吊り下げた可撓材にて摺動部を覆うことにより、起伏回動時に摺動部にて穀粒をすり潰し挟み込んで傷を付けることがなくなり、スムーズな穀粒排出作業が行える。
【0010】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。図1は本発明を実施した穀粒ホッパの一部断面とした斜視図、図2は穀粒ホッパの後面断面図、図3は穀粒ホッパの穀粒貯留時の後面断面図、図4は穀粒ホッパの穀粒排出時の作用図、図5は従来の穀粒ホッパとの比較をした比較図である。
【0011】
図1及び図2において、Aは穀粒ホッパで走行車の荷台に載置可能とし、圃場で収獲された穀粒を貯留し乾燥施設や貯蔵庫まで運搬し排出するものである。この穀粒ホッパAは、断面が角形のパイプ材にて直方体形状に枠組された機枠体1と、この機枠体1の上面に上部開口部を形成し内方側面に四方を囲むように側面板2と、機枠体1の底部中央から後面視V字状とした底面傾斜板3,3と、この底面傾斜板3,3により形成されたV字状谷部に配置された排出搬送体4から構成される。
【0012】
側面板2は、排出搬送体4にて排出搬送される穀粒の排出口43を設けた後面板21と、この後面板21に対向する前面板22と、左右長手方向の側面にそれぞれ側面板23,23を設け、機枠体1の内側四方を囲むよう形成される。
【0013】
機枠体1の底部中央には後面視V字状とした底面傾斜板3,3が左右対称に設けられ、この底面傾斜板3,3により形成されたV字状谷部に配置された排出搬送体4は、前記後面板21と前面板22の長手方向に両端を支持され回転自在としたスクリュ41と、このスクリュ41の下方に略U字状に設けた搬送樋42にて構成され、スクリュ41の搬送方向終端部は、前記後面板21に設けた排出口43へ接続される。
【0014】
スクリュ41の他方端部には、前記前面板22より回転軸41aが突設し、機枠体1の枠内底部前方に配置された電動モータMにてベルト44を介し、後面板21に設けた起動スイッチSを押すことにより、電動モータMを起動しスクリュ41は回転駆動される。
【0015】
5は搬送ホースで、排出口43に着脱自在とする着脱金具51と、この着脱金具51より後方へ適宜長さとしたホース52と、ホース52の内部にバネ形コンベア53を回転自在に設けてあり、着脱金具51が排出口43に装着されるとバネ形コンベア53の基端部が前記スクリュ41と係合し、バネ形コンベア53は回転駆動される。穀粒ホッパA内に貯留された穀粒は、排出搬送体4のスクリュ41により排出口43へ移送し、排出口43からは回転駆動されたバネ形コンベア53にてホース52内を移送し、他端部に設けたホース排出口54より排出される。
【0016】
左右対称に設けた底面傾斜板3,3は、傾斜面略中央部に屈曲部3aを設け、下方に第1傾斜板31と上方に第2傾斜板32を設け構成される。第1傾斜板31の傾斜下降端部は、前記排出搬送体4にU字状に形成された搬送樋42の立ち上がる長手方向側面壁の上端部に蝶番33を介し起伏回動自在に連結される。
【0017】
そして、起伏回動自在とした第1傾斜板31,31の下面側には、底面傾斜板3,3を上方に付勢する圧縮弾性体6を機枠体1の下枠より複数架設する。前記圧縮弾性体6にはガススプリングを用い、このガススプリングはガス室に高圧ガスを封入し、ピストンロットを伸び方向に反発力をもたせたもので、この反発力を利用し底面傾斜板3,3を上方に付勢することが可能となる。
【0018】
第2傾斜板32は、第1傾斜板31と屈曲部より第1傾斜板に対しさらに上向きに傾斜した姿勢で傾斜上昇端部を前記左右の側面板23,23の内側へ摺動自在に当接させる。
【0019】
第2傾斜板32と側面板23が摺動自在に当接する当接部には、可撓材7が側面板23の内側長手方向に吊り下げられ、当接部を覆うよう設けられている。
【0020】
81,81は底面係止板で、前記底面傾斜板3,3の第1傾斜板31,31を図3に示すよう穀粒ホッパAに穀粒Kが貯留され下降回動したときに係止するものであり、82,82は側面係止板で、前記底面傾斜板3,3の第2傾斜板32,32を前記同様ホッパ内に穀粒が貯留され下降回動したときに係止するものである。底面係止板81,81と側面係止板82,82は、穀粒ホッパAに貯留された穀粒Kの重量を支持するとともに移動時の振動を受け、圧縮弾性体であるガススプリングへの衝撃を排除する。
【0021】
次に、図4,図5に基づいて作用について説明する。穀粒ホッパA内に穀粒Kが貯留されると、穀粒Mの重量にて底面傾斜板3,3を上方に付勢する圧縮弾性体6であるガススプリングが圧縮し、底面傾斜板3,3は、第2傾斜板32,32を屈曲部3a,3aを中心に屈曲回動しながら側面板23,23に当接したまま下方へ摺動させ、第1傾斜板31,31は蝶番33,33を中心に下降回動する。
【0022】
下降回動した底面傾斜板3,3の第1傾斜板31,31と第2傾斜板32,32はそれぞれ底面係止板81,81と側面係止板82にて図4(イ)に示すよう係止され、底面傾斜板3,3は後面視略水平に展開されホッパ内の収容容積を増加する。このように係止することにより、圧縮弾性体6であるガススプリングが圧縮しすぎないようにしている。
【0023】
ホッパ内に貯留した穀粒Kを走行車にて乾燥施設や貯蔵庫に運搬し、排出搬送体4及び搬送ホース5により穀粒排出作業が行われる。起動スイッチSを押すことにより、排出搬送体4のスクリュ41と搬送ホース5に備えたバネ形コンベア53は電動モータMにて回転駆動され排出作業が開始されると、図4(ロ)に示すように、スクリュ41の上方に貯留された穀粒Kから排出され、次第に減少してくると図4(ハ)に示すように底面傾斜板3,3上に貯留された穀粒Kが減少し、底面傾斜板3,3にかかる穀粒Kの重量が減少するので、圧縮弾性体6であるガススプリングが徐々に伸張してくる。
【0024】
そして、図4(ニ)に示すように底面傾斜板3,3は、上昇回動し再び後面視V字状となる係斜面を形成し、ホッパ内に残る少量の穀粒Kを中央底部に集め排出搬送体4の排出樋に流し込み穀粒排出作業がスムーズに行われるよう排出の補助をする。
【0025】
又、底面傾斜板3,3の第2傾斜板32と側面板23との当接部を可撓材7にて覆うよう設けてあるので、穀粒Kが当接部に対し遮断されるので、底面傾斜板3,3の上昇回動に伴い摺動する当接部によって、穀粒Kがすり潰され傷付くことがない。
【0026】
図5に示すように、本実施例における穀粒ホッパAは従来公知である底面傾斜板が起伏回動せず、同量の穀粒Kを貯留可能とした収容容積を具備した穀粒ホッパBと比較すると、機体全高を従来穀粒ホッパBの全高HBに対し全高HAまで低く構成することが可能となり、さらに穀粒Kの積載重心位置を従来穀粒ホッパBの重心GBの高さLBに対し、重心GAの高さLAまで低くすることができ、本実施例における穀粒ホッパAを載置した走行車は安定して走行することができるようになる。
【0027】
【発明の効果】
以上のように構成された穀粒ホッパは、機体をコンパクトに構成し、且つ収容容積を増すことができ、さらに穀物貯留時の重心を低くすることができ運搬時の走行バランスを良好とする。さらに、圧縮弾性体にて底面傾斜板を上方に付勢することで穀粒の排出を補助し排出効率が向上する。
【0028】
又、底面傾斜板を上方に付製する圧縮弾性体にガススプリングを用いたことにより、ホッパ内にコイルバネを吊設した構成より簡単に構成で、且つ部品点数を減らすことができコストダウンすることができる。
【0029】
又、起伏回動自在とした底面傾斜板とこの底面傾斜板が当接する側面板の摺動部には、側面板内側より下方に吊り下げた可撓材にて摺動部を覆うことにより、起伏回動時に摺動部にて穀粒をすり潰し挟み込んで傷を付けることがなくなり、スムーズな穀粒排出作業が行える。

Eliminate shock.
[0021]
Next, the operation will be described with reference to FIGS. When the kernel K is stored in the kernel hopper A, the gas spring, which is a compression elastic body 6 for urging the bottom inclined plates 3 and 3 upward by the weight of the grain M, is compressed, and the bottom inclined plate 3 is compressed. , 3 slide the lower part of the second inclined plates 32, 32 in contact with the side plates 23, 23 while bending and rotating the second inclined plates 32, 32 around the bent parts 3a, 3a. The first inclined plates 31, 31 are hinged. Rotate downward around 33,33.
[0022]
The first inclined plates 31, 31 and the second inclined plates 32, 32 of the bottom inclined plates 3, 3 which have been rotated downward are shown in FIG. 4 (a) by bottom engagement plates 81, 81 and side engagement plates 82, respectively. So that the inclined bottom plates 3 and 3 are deployed substantially horizontally when viewed from the rear, so as to increase the storage volume in the hopper. This locking prevents the gas spring, which is the compression elastic body 6, from being excessively compressed.
[0023]
The grain K stored in the hopper is transported to a drying facility or a storage by a traveling vehicle, and the grain discharging operation is performed by the discharge carrier 4 and the transport hose 5. When the start switch S is pressed, the screw 41 of the discharge conveyance body 4 and the spring-type conveyor 53 provided on the conveyance hose 5 are driven to rotate by the electric motor M and the discharge operation is started, as shown in FIG. As shown in FIG. 4 (c), when the kernel K stored above the screw 41 is discharged and gradually decreases, the kernel K stored on the bottom inclined plates 3, 3 decreases. Since the weight of the grain K applied to the bottom inclined plates 3 and 3 decreases, the gas spring as the compression elastic body 6 gradually expands.
[0024]
Then, as shown in FIG. 4 (d), the bottom inclined plates 3, 3 are rotated upward to form a V-shaped engagement slope again when viewed from the rear, and a small amount of kernel K remaining in the hopper is placed at the center bottom. It is poured into the discharge gutter of the collecting and discharging carrier 4 and assists in discharging so that the grain discharging operation can be performed smoothly.
[0025]
Further, since the contact portion between the second inclined plate 32 of the bottom inclined plates 3 and 3 and the side plate 23 is provided so as to be covered with the flexible material 7, the kernel K is blocked from the contact portion. The grain K is not crushed and damaged by the contact portion that slides with the upward rotation of the bottom inclined plates 3 and 3.
[0026]
As shown in FIG. 5, the grain hopper A in the present embodiment has a conventionally known grain hopper B having a storage volume capable of storing the same amount of grains K without the inclined bottom plate being swung up and down. In comparison with the above, it is possible to configure the total height of the machine body to be lower than the total height HB of the conventional grain hopper B to the total height HA, and furthermore, the loading center of the kernel K is set to the height LB of the center of gravity GB of the conventional grain hopper B. On the other hand, the height can be reduced to the height LA of the center of gravity GA, and the traveling vehicle on which the grain hopper A in this embodiment is mounted can run stably.
[0027]
【The invention's effect】
The grain hopper configured as described above has a compact body, can increase the storage capacity, can lower the center of gravity during grain storage, and can improve traveling balance during transportation. Further, by pressing the bottom inclined plate upward by the compression elastic body, the discharge of the grain is assisted and the discharge efficiency is improved.
[0028]
In addition, by using a gas spring for the compression elastic body that attaches the bottom inclined plate to the upper side, the configuration is simpler than the configuration in which the coil spring is suspended in the hopper, and the number of parts can be reduced, thereby reducing the cost.
