【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)
【0003】
【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により上昇回動する底面傾斜板と四方を囲む側面板の摺動部にて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、ホッパ内の収容量の向上を計り、機体を軽量且つコンパクトに構成し穀物貯留時の重心を低くするとともに、穀粒排出時に穀粒を傷付けることなくホッパ内の穀粒残量を低減できる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と、この機枠体の内側側面四方を囲む側面壁と、前記機枠体の内方底部より後面視略V字状とした傾斜面を有する底面傾斜板と、この底面傾斜板のV字状谷部に排出搬送体とを設け、前記底面傾斜は傾斜下降辺に設けた回動支点により起伏回動可能に構成した穀粒ホッパにおいて、前記底面傾斜板は剛性体にて構成され、前記側面壁は可撓性を有するシート材にて構成し、このシート材の下部を前記底面傾斜板と連結し、この底面傾斜板を上方に付勢する圧縮弾性体を設けたことにより、まず、側面壁をシート材にて形成することで機体を軽量に構成することができ、又、起伏回動する底面傾斜板が摺動部を有することがなく排出時に穀粒を傷付けることがない。
【0008】
そして、ホッパ内に穀粒が貯留されると、底面傾斜板は下降回動をし、この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ることできるので、運搬時の走行バランスを安定させる。さらに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、底面傾斜板を穀粒の安息角以上に上昇回動させ穀粒の排出を補助しホッパ内の穀粒残量を低減できる。
【0009】
又、圧縮弾性体は、底面傾斜板の下面に設けるとともに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、コイルバネやバネカバー等の部品点数を減らしコストダウンすることができるとともに、簡単な構成で且つ組立性が向上する。
【0010】
又、底面傾斜板は、傾斜下降辺の長さに対し傾斜上昇辺の長さを短くした台形形状としたことにより、側面四方を囲むよう構成し底面傾斜板に連結されたシート材は、上部開口部の四隅角部より排出搬送体の端部に向け稜線を形成し、この稜線に対して内側にシート連結部を設けることで上部開口部の四隅角部より排出搬送体の端部へ向けた稜線部分を張った状態を保持したまま底面傾斜板は起伏回動するため、シート材は弛むことがなく穀粒の排出がスムーズに行える。
【0011】

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斜視図、図2は穀粒ホッパの側面断面図、図3は穀粒ホッパの後面断面図、図4は穀粒貯留時の穀粒ホッパの後面断面図、図5は穀粒貯留時の穀粒ホッパの平面図、図6は穀粒排出時の作用図、図7は従来の穀粒ホッパと比較した比較図である。
【0012】
図1,図2及び図3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可撓性を有するシート材で形成された側面シート2と、機枠体1の底部中央に長手方向の一端側である後面視にて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。
【0013】
機枠体1は平面視矩形状に枠組みしたベース枠11と、ベース枠11の四隅角部に立設した支柱枠12と支柱枠12の上端部間に横架された支持枠13から構成される。支持枠13は支柱枠12に対し上端部に設けたストッパ14にて着脱自在としてある。
【0014】
機枠体1のベース枠11の上面中央より底部中央には、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字状谷部でベース枠11上に配置された排出搬送体4は、ベース枠11の長手方向両端中央部に設けた支持ブラケット45,45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の搬送方向終端部である後面側の支持ブラケット45には排出口43が設けられている。
【0015】
スクリュ41の他方端部には、回動軸41aが排出口43を設けた後面側の支持ブラケット45に対向する前面側の支持ブラケット45より突設し、機枠体1のベース枠11の前方上部に配置された電動モータMにてベルト44を介し、機枠体1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。
【0016】
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。
【0017】
左右対称に設けた底面傾斜板3,3は剛性体にて傾斜面を構成し、傾斜下降辺は、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31を介し起伏回動自在に連結され、底面傾斜板3,3を上方に付勢する圧縮弾性体6を底面傾斜板3,3の下面と機枠体1のベース枠11との間に複数架設する。この圧縮弾性体6にはガススプリング61を用い、このガススプリング61はガス室に高圧ガスを封入し、ピストンロットに伸び方向の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】
可撓性を有するシート材にて形成された側面シート2は、上部開口縁にシート材を折り返し縫い合わせ筒状に形成した挿通筒21を設け、この挿通筒21に前記機枠体1の着脱自在とした支持枠13が挿通され、枠内下方に向け側面シート2を吊持する。
【0019】
側面シート2の下部開口縁は、前記底面傾斜板3,3の傾斜上昇辺及び傾斜側辺、そして支持ブラケット45,45に連結され穀粒を貯留可能とする。
【0020】
底面傾斜板3,3の傾斜上昇辺は、傾斜下降辺に対し短く構成し台形形状とし、この傾斜上昇辺の長手方向中央部より底面傾斜板3,3の傾斜角よりさらに上方に向け傾斜させた傾斜補助ロット32が設けてある。
【0021】
7は底面係止板で、図4に示すよう穀粒ホッパAに穀粒Kが貯留され底面傾斜板3,3が下降回動したときに当接し係止するものであり、穀粒ホッパA内に貯留された穀粒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6であるガススプリング61への衝撃を排除できる。
【0022】
底面傾斜板3,3を台形形状とすることにより、底面傾斜板3,3がガススプリング61にて上方に付勢された状態で、図2及び図5の2点鎖線で示すように、側面シート2は上部開口部の四隅角部より排出搬送体4の端部に向け稜線が形成され、この稜線に対し側面シート2の連結部が内側に設けられるので底面傾斜板は起伏回動しても上部開口部の四隅角部より排出搬送体4の端部に向け稜線が形成された側面シート2を張った状態に保持する。底面傾斜板3,3に設けた傾斜補助ロット32,32は、底面傾斜板3,3が上方に付勢された状態で側面シート2の長手方向側面の弛みを解消するものである。
【0023】
次に、図4,図5及び図6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K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61が圧縮し、底面傾斜板3,3は、蝶番31,31を中心に下降回動する。
【0024】
下降回動した底面傾斜板3,3は底面係止板7,7に図4に示すよう当接し係止され、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61が圧縮しすぎないようにするとともに、穀粒Kの重量を支持し移動時の振動によるガススプリング61への衝撃を排除するものである。
【0025】
ホッパ内に貯留した穀粒Kは走行車にて乾燥施設や貯蔵庫に運搬され、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6(イ)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6(ロ)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に加わる穀粒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61が徐々に伸張してくる。この時側面シート2は、上部開口部の四隅角部より排出搬送体4の端部に向け稜線が形成される。
【0026】
そして、図6(ハ)に示すように底面傾斜板3,3は、穀粒の安息角以上に上昇回動し再び後面視V字状となる傾斜面を形成する。この時、側面シート2の長手方向側面は傾斜補助ロット32,32により内方へ突出され弛むことがない。又、側面シート2は上部開口部の四隅角部より排出搬送体4の端部に向けた稜線部を張った状態に保持し、この稜線の内側を底面傾斜板が上昇回動するため底面傾斜板の傾斜側辺との間に弛みがなく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の搬送樋42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補助しホッパ内の穀粒Kの残量を低減する。
【0027】
図7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。
【0028】
【発明の効果】
以上のように構成された穀粒ホッパは、まず、側面壁をシート材にて形成することで機体を軽量に構成することができ、又、起伏回動する底面傾斜板が摺動部を有することがなく排出時に穀粒を傷付けることがない。そして、ホッパ内に穀粒が貯留されると底面傾斜板は下降回動をし、この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ることできるので、運搬時の走行バランスを安定させる。さらに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、底面傾斜板を穀粒の安息角以上に上昇回動させ穀粒の排出を補助しホッパ内の穀粒残量を低減できる。
【0029】
又、底面傾斜板を上方に付勢する圧縮弾性体には、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、コイルバネやバネカバー等の部品点数を減らしコストダウンすることができるとともに、簡単な構成で且つ組立性を向上させる。
【0030】
又、底面傾斜板は、傾斜下降辺の長さに対し傾斜上昇辺の長さを短くした台形形状としたことにより、側面四方を囲むよう構成し底面傾斜板に連結されたシート材は、上部開口部の四隅角部より排出搬送体の端部に向け稜線を形成し、この稜線に対して内側にシート連結部を設けることで上部開口部の四隅角部より排出搬送体の端部へ向けた稜線部分を張った状態を保持したまま底面傾斜板は起伏回動するため、シート材は弛むことがなく穀粒の排出がスムーズに行える。

[Patent Document 1]
JP-A-63-87137 [0004]
[Problems to be solved by the invention]
According to the above-mentioned prior art, there is a problem that the flow of the grain is hindered when the grain is discharged because the coil spring is suspended in the grain hopper. In addition, there is a problem that the coil spring protrudes from the spring cover when the kernel is stored, and the kernel reaching the periphery of the protruding coil spring does not operate the coil spring properly.
[0005]
The grain may be damaged by the sliding portion between the bottom inclined plate that rotates upward and the side plate that surrounds the four sides due to the coil spring that contracts in synchronization with the discharge of the grain. Further, since the coil spring is provided so as to be suspended from a suspension frame disposed above the grain hopper, there is a problem that the overall height of the machine body is increased.
[0006]
Therefore, the present invention aims to improve the storage capacity in the hopper, reduce the center of gravity when storing the grains by configuring the aircraft to be lightweight and compact, and reduce the amount of the grains remaining in the hopper without damaging the grains when discharging the grains. It is an object of the present invention to provide a grain hopper capable of reducing the grain size.

In the above, the bottom inclined plate is formed of a rigid body, the side wall is formed of a flexible sheet material, a lower portion of the sheet material is connected to the bottom inclined plate, and the bottom inclined plate is moved upward. By providing the compression elastic body that urges the body, first, the side wall is formed of a sheet material so that the body can be made lightweight. It does not have and does not hurt the grains when discharged.
[0008]
When the kernels are stored in the hopper, the bottom inclined plate rotates downward, and at the same time as the downward rotation, the compression elastic body can be compressed to increase the capacity of the hopper. To stabilize the running balance. Further, when the stored grains are discharged by the discharge conveyance body, the compression elastic body gradually expands, and the bottom inclined plate is raised and rotated above the angle of repose of the grains to assist in the discharge of the grains, and a hopper is provided. It is possible to reduce the remaining amount of grains in the inside.
[0009]
In addition, the compression elastic body is provided on the lower surface of the bottom inclined plate and uses a gas spring filled with high-pressure gas, so that the number of parts such as a coil spring and a spring cover can be reduced, and the cost can be reduced. The assemblability is improved.
[0010]
In addition, the bottom inclined plate has a trapezoidal shape in which the length of the inclined rising side is shorter than the length of the inclined descending side, so that the sheet material connected to the four side surfaces and connected to the bottom inclined plate is the upper part. A ridge line is formed from the four corners of the opening toward the end of the discharge conveyance body, and a sheet connection portion is provided inside the ridge line so that the four corners of the upper opening are directed toward the end of the discharge conveyance body. Since the bottom inclined plate rotates up and down while maintaining the state where the ridge portion is stretched, the sheet material can be smoothly discharged without loosening of the sheet material.

Next, the operation will be described with reference to FIGS. When the kernel K is stored in the kernel hopper A, the gas spring 61 which is a compression elastic body 6 for urging the bottom inclined plates 3 and 3 upward by the weight of the kernel K is compressed, and the bottom inclined plate is compressed. 3, 3 rotate downward about hinges 31, 31.
[0024]
As shown in FIG. 4, the inclined bottom plates 3 and 3 that have been rotated downward contact the bottom engaging plates 7 and 7 as shown in FIG. 4, and the inclined bottom plates 3 and 3 are deployed substantially horizontally when viewed from the rear to reduce the storage volume in the hopper. To increase. By locking in this manner, the gas spring 61, which is the compression elastic body 6, is prevented from being excessively compressed, and at the same time, supports the weight of the grain K and eliminates an impact on the gas spring 61 due to vibration during movement. Things.
[0025]
The grains K stored in the hopper are transported to a drying facility or a storage by a traveling vehicle, and a 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 to start the discharge operation, as shown in FIG. As described above, when the kernel K stored above the screw 41 is discharged and gradually decreases, the kernel K stored on the bottom inclined plates 3 decreases as shown in FIG. Since the weight of the kernel K applied to the bottom inclined plates 3 and 3 decreases, the gas spring 61 as the compression elastic body 6 gradually expands. At this time, the side sheet 2 is formed with a ridge line from the four corners of the upper opening toward the end of the discharge conveyance body 4.
[0026]
Then, as shown in FIG. 6 (c), the bottom inclined plates 3 and 3 form an inclined surface which rises above the angle of repose of the grain and turns again into a V-shape in rear view. At this time, the side surfaces in the longitudinal direction of the side sheet 2 are projected inward by the inclined auxiliary lots 32, 32 and are not loosened. Also, the side sheet 2 is held in a state in which a ridge line extending from the four corners of the upper opening toward the end of the discharge conveyance body 4 is stretched. A small amount of grain K remaining in the hopper without slack between the inclined side of the plate and the hopper is collected at the bottom of the center and poured into the conveying gutter 42 of the discharging and conveying body 4 to assist in discharging the grain so that the grain discharging operation can be smoothly performed. To reduce the remaining amount of the kernel K.
[0027]
As shown in FIG. 7, a 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 rotating 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.
[0028]
【The invention's effect】
In the grain hopper configured as described above, first, the side wall is formed of a sheet material so that the body can be made lightweight, and the bottom inclined plate that moves up and down has a sliding portion. There is no damage to the grain during discharge. When the grains are stored in the hopper, the bottom inclined plate rotates downward, and at the same time as the downward rotation, the compression elastic body can be compressed to increase the storage capacity of the hopper. Stabilize the running balance. Further, when the stored grains are discharged by the discharge conveyance body, the compression elastic body gradually expands, and the bottom inclined plate is raised and rotated above the angle of repose of the grains to assist in the discharge of the grains, and a hopper is provided. It is possible to reduce the remaining amount of grains in the inside.
[0029]
A gas spring filled with high-pressure gas is used for the compression elastic body that urges the bottom inclined plate upward, so that the number of components such as coil springs and spring covers can be reduced, and the cost can be reduced. And improve assemblability.
[0030]
In addition, the bottom inclined plate has a trapezoidal shape in which the length of the inclined rising side is shorter than the length of the inclined descending side, so that the sheet material connected to the four side surfaces and connected to the bottom inclined plate is the upper part. A ridge line is formed from the four corners of the opening toward the end of the discharge conveyance body, and a sheet connection portion is provided inside the ridge line so that the four corners of the upper opening are directed toward the end of the discharge conveyance body. Since the bottom inclined plate rotates up and down while maintaining the state where the ridge portion is stretched, the sheet material can be smoothly discharged without loosening of the sheet material.
