Description

本発明は、土砂等の粉粒体状の物質を上方に搬送する、粉粒体物質の搬送装置に関するものである。   TECHNICAL FIELD The present invention relates to a powder material transport device that transports a powdery material such as earth and sand upward.

従来の、この種の搬送装置としては、図２に示すように、立設した搬送パイプ１内の両側にリンクチェーン２、２を沿設し、これらのリンクチェーン２、２間に搬送プレート３を取り付けて、該搬送プレート３をリンクチェーン２に沿って所定間隔で多数配置し、上記搬送パイプ１の下端部を横方向に曲げて、この横方向の搬送パイプ１′の上側にホッパー４ａ及び供給スクリュー４ｂ等から成る供給装置４を設置したものがあった。（例えば、特許文献１参照）
また従来、図３に示すように、上記搬送パイプ１の下端部の曲げ部分（コーナー部１″）に、スプロケット５（或いはガイドローラ）を設けて、上記リンクチェーン２の方向を変えるようにしていた。 As shown in FIG. 2, a conventional conveying apparatus of this type includes link chains 2, 2 provided on both sides of an upright conveying pipe 1, and a conveying plate 3 between the link chains 2, 2. And a plurality of the transport plates 3 are arranged along the link chain 2 at a predetermined interval, the lower end of the transport pipe 1 is bent in the lateral direction, and a hopper 4a and a hopper 4a are placed on the upper side of the lateral transport pipe 1 '. There was one provided with a supply device 4 composed of a supply screw 4b and the like. (For example, see Patent Document 1)
Conventionally, as shown in FIG. 3, a sprocket 5 (or a guide roller) is provided at the bent portion (corner portion 1 ″) of the lower end portion of the transport pipe 1 so as to change the direction of the link chain 2. It was.

しかしながら、上記コーナー部１″では、搬送される粉粒体物質が圧密され、安定した搬送が行えないだけでなく、特に物質が礫等の場合には、閉塞を起こす恐れがあった。
また、スプロケット５を設けたものは、リンクチェーン２との間に異物を噛み込んで、スプロケット５の歯先が破損し、その結果、チェーンが脱落して搬送不可となる恐れもある。
さらに、従来のコーナー部１″の構造では、曲がり半径が小さくなるため、チェーンが屈曲する際、負荷荷重が集中的にリンクチェーンにかかって破損し易い等の問題点があった。
特開平１１−２４０６０７号公報 However, in the corner portion 1 ″, the conveyed granular material is not compacted and cannot be stably conveyed. In particular, when the material is gravel or the like, there is a risk of blockage.
In addition, in the case where the sprocket 5 is provided, foreign matter may be caught between the link chain 2 and the tooth tip of the sprocket 5 may be damaged. As a result, the chain may drop off and the conveyance becomes impossible.
Further, in the conventional structure of the corner portion 1 ″, since the bending radius is small, there is a problem that when the chain is bent, the load is concentrated on the link chain and is easily damaged.
Japanese Patent Laid-Open No. 11-240607

本発明が解決しようとする課題は、リンクチェーン等の部材に掛かる負荷を低減し、部材の破損を少なくしたり寿命を長くすることによって、トラブルの発生を少なくし、メンテナンスコストを低減することができる粉粒体物質の搬送装置を提供することにある。   The problem to be solved by the present invention is to reduce the load applied to members such as link chains, to reduce the occurrence of trouble and to reduce the maintenance cost by reducing the breakage of the members and extending the life. An object of the present invention is to provide a transfer device for a granular material.

本発明の粉粒体物質の搬送装置は、立設した搬送パイプ内にリンクチェーンを沿設して、該リンクチェーンに搬送プレートを所定間隔で多数取り付け、上記搬送パイプ下部のコーナー部を介して横方向の搬送パイプに接続し、該横方向の搬送パイプ上側に粉粒体物質の供給手段を設置してなる粉粒体物質の搬送装置において、上記コーナー部に上記リンクチェーンの曲がりを案内する複数のガイドローラを弧状に配列したことを特徴とする。また、上記コーナー部とホッパーを同一の空間とし、コーナー部内部を広くするように構成したことも特徴とするものである。   The carrier device for a granular material according to the present invention has a link chain installed in an upright delivery pipe, a large number of delivery plates are attached to the link chain at a predetermined interval, and the corner is formed at the lower part of the delivery pipe. In a granular material conveying device, which is connected to a horizontal conveying pipe and has a granular material supplying means installed on the upper side of the horizontal conveying pipe, the bend of the link chain is guided to the corner portion. A plurality of guide rollers are arranged in an arc shape. Further, the corner portion and the hopper are formed in the same space, and the interior of the corner portion is widened.

本発明の粉粒体物質の搬送装置は、下記のような利点がある。
１）定量的な搬送を行なうことができ、その結果、定量供給装置を別途必要としないため、コストを低減できる。
２）安定した搬送が可能となるため、安全性が向上する。
３）部品の寿命が延びることによるメンテナンスコストを低減することができる。 The granular material transport apparatus of the present invention has the following advantages.
1) Quantitative conveyance can be performed, and as a result, a separate quantitative supply device is not required, thereby reducing costs.
2) Since stable conveyance is possible, safety is improved.
3) The maintenance cost due to the extended life of the parts can be reduced.

図１は、本発明装置の一実施例を示すもので、搬送パイプ１、横方向の搬送パイプ１′、リンクチェーン２、搬送プレート３は、上記従来装置の対応する各部材と同じ構造および機能を有する。上記リンクチェーン２は、エンドレスに構成され、適当な駆動手段により駆動され、上記搬送プレート３を移動せしめるように構成されている。   FIG. 1 shows an embodiment of the apparatus of the present invention. The transport pipe 1, the lateral transport pipe 1 ', the link chain 2 and the transport plate 3 have the same structure and function as the corresponding members of the conventional apparatus. Have The link chain 2 is configured to be endless and is configured to move the transport plate 3 by being driven by an appropriate driving unit.

上記搬送パイプ１下部のコーナー部１″には、上記リンクチェーン２の曲がりを案内する複数（本実施例では５個）のガイドローラ６が全体として弧状に配列されている。この弧状配列によりコーナー部１″の曲率半径を大きくすることができ、その結果、リンクチェーン２を無理なく案内しながら移動方向を円滑に転換することができ、リンクチェーン２の摩耗や破損を低減することができる。   A plurality (five in this embodiment) of guide rollers 6 for guiding the bending of the link chain 2 are arranged in an arc shape as a whole at the corner portion 1 ″ at the lower portion of the conveying pipe 1. The radius of curvature of the portion 1 ″ can be increased. As a result, the moving direction can be smoothly changed while guiding the link chain 2 without difficulty, and wear and breakage of the link chain 2 can be reduced.

また、上記コーナー部１″とホッパーが同一の空間Ｓを広くしている。これにより、コーナー部１″での粉粒体物質の圧密を防ぐことができ、搬送パイプ１への定量かつ安定した供給が可能となる。   Further, the corner portion 1 ″ and the hopper widen the same space S. As a result, it is possible to prevent the compacting of the granular material in the corner portion 1 ″, and the amount and stability to the conveying pipe 1 can be stabilized. Supply becomes possible.

７は供給ホッパーであって、この中に粉粒体物質を投入して、横向きの搬送パイプ１′に供給するようになっている。本供給部には、特に供給スクリューなどの定量供給手段を設ける必要はない。   Reference numeral 7 denotes a supply hopper, in which the granular material is charged and supplied to the sideways conveying pipe 1 '. The supply section need not be provided with a fixed supply means such as a supply screw.

上記実施例において、上記搬送パイプ１は鉛直に立設されているが、斜めであってもよい。また、上記横向きの搬送パイプ１′は、水平になっているが、これも斜めであってもよい。   In the embodiment described above, the transport pipe 1 is erected vertically, but may be inclined. Moreover, although the said horizontal conveyance pipe 1 'is horizontal, this may also be diagonal.
