本発明は、ホツパー内に貯えられた被搬送物を
スクリユーコンベアによつて搬出する装置に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for transporting objects stored in a hopper using a screw conveyor.
従来、この種の搬出装置としては第１図、第２
図に示すように、ホツパーａの底部に複数の掻寄
せスクリユーコンベアｂを並設してホツパーａ内
の被搬送物を、前記ホツパーａの底部一側に形成
した凹陥部ｃに搬送し、この凹陥部ｃ内に搬出ス
クリユーコンベアｄを設け、凹陥部ｃに搬送され
た被搬送物を搬出スクリユーコンベアｄによつて
搬出するようにしたものが知られている。 Conventionally, this type of unloading device is shown in Figures 1 and 2.
As shown in the figure, a plurality of scraping screw conveyors b are arranged in parallel at the bottom of the hopper a, and the objects to be conveyed in the hopper a are conveyed to a recess c formed on one side of the bottom of the hopper a, It is known that a carry-out screw conveyor d is provided in the concave part c, and the conveyed object conveyed to the concave part c is carried out by the carry-out screw conveyor d.
しかし、この構造であると掻寄せスクリユーコ
ンベアｂによつて搬出スクリユーコンベアｄまで
被搬送物を搬送せねばならないので、搬出スクリ
ユーコンベアｄを底部一側に形成した凹陥部ｃ内
に設けて搬出スクリユーコンベアｄと掻寄せスク
リユーコンベアｂとが干渉しないようにしてい
る。 However, with this structure, the objects must be conveyed to the discharge screw conveyor d by the scraping screw conveyor b, so the discharge screw conveyor d is provided in the recess c formed on one side of the bottom. This prevents interference between the unloading screw conveyor d and the scraping screw conveyor b.
このために、ホツパーａの底部には凹陥部ｃを
形成せねばならず、ホツパーａの全高Ｈがそれだ
け高くなつてしまうので、トラツク等で被搬送物
をホツパーに投入する際に他の揚送装置を設置す
るか、若しくはホツパーの据付地盤を掘下げねば
ならず、それだけコストが高くなつてしまう。 For this reason, it is necessary to form a concave part c at the bottom of hopper a, and the overall height H of hopper a increases accordingly. It is necessary to install a device or dig down the ground for installing the hopper, which increases the cost accordingly.
また、複数の掻寄せスクリユーコンベアｂを常
時駆動せねばならず、消費駆動エネルギーが大と
なつてしまう。 Furthermore, the plurality of scraping screw conveyors b must be constantly driven, resulting in a large amount of driving energy consumption.
そこで、ホツパーの底部に搬出スクリユーコン
ベアを設け、この搬出スクリユーコンベアによつ
てホツパー内の被搬送物を直接搬出するようにし
て、ホツパーに凹陥部を形成しなくとも良いよう
にすることが考えられるが、この様にすると被搬
送物がホツパー内でブリツジ現象を起し、被搬送
物を効率良くスムーズに搬出できなくなつてしま
う。 Therefore, it is possible to provide an unloading screw conveyor at the bottom of the hopper so that the conveyed objects in the hopper are directly unloaded, thereby eliminating the need to form a recess in the hopper. It is conceivable that if this is done, the object to be conveyed will cause a bridging phenomenon within the hopper, making it impossible to carry out the object efficiently and smoothly.
本発明は上記の事情に鑑みなされたものであ
り、その目的は、ホツパーに貯えられた被搬送物

６2，６4，６5，６7の回転によつて被搬送物絡ま
りを解きほぐすようにする。 If the conveyed objects in the hopper A are carried out in the above manner, a bridging phenomenon will occur, so the first to eighth scraping screw conveyors 61 to
6 8 is rotated to scrape the conveyed objects inside the hopper A onto the axially intermediate portions of the respective scraping screw conveyors 6 1 to 6 8 (that is, the intermediate portions in the direction of both end walls 3 and 3' of the hopper A). The objects to be conveyed are kept in a medium-height state, and the entanglements of the objects are loosened by the rotation of the second, fourth, fifth , and seventh scraping screw conveyors 6 2 , 6 4 , 6 5 , and 6 7 .

Screw conveyor 5 for smoothly transporting objects
It can be transported by
また、各掻寄せスクリユーコンベア６1〜６8は
常時駆動させる必要はなく、間欠的に駆動すれば
良いので、消費駆動エネルギーを低減できる。 Moreover, each of the scraping screw conveyors 6 1 to 6 8 does not need to be driven all the time, but only needs to be driven intermittently, so that the consumed driving energy can be reduced.
また、ホツパーＡ内で被搬送物は中高の状態と
なるので、被搬送物の残量が少なくなつても搬出
スクリユーコンベア５によつて確実に搬出でき
る。 Moreover, since the objects to be transported are in a medium-height state in the hopper A, even if the remaining amount of objects to be transported is small, they can be reliably transported by the unloading screw conveyor 5.
また、ホツパーＡの底壁１はＶ字状となつてい

Screw conveyor 5 carries out the objects stored in
By driving a plurality of scraping screw conveyors arranged in parallel on both sides of this unloading screw conveyor 5, the conveyed objects at the bottom of the hopper A can be transported to the axially intermediate part and both axially ends. Because it is possible to untangle the transported object at the same time by transporting it toward the side and bringing the transported object in the hopper A to a medium-height state, the transported object at the bottom of the hopper A can be removed from the screen without causing a bridging phenomenon. It can be transported sequentially towards Yukon Bear 5.
