Description

本発明はグリズリ装置に関するもので、特にグリズリバー間に土砂や土、小塊が挟まり、目詰まりが生じるのを防止する装置に関する。   The present invention relates to a grizzly device, and more particularly, to a device that prevents clogging caused by earth and sand, earth, or a small lump being sandwiched between grizzly bars.

原石山で発破により崩した岩石(原石)には石の目(割れ目)に土砂や土が自然に挟まれている。特に、１ｍｍ以下の細粒分には土砂や土の不純物がほとんどを占めている。このような土砂や土が製品(砕石)に含まれると商品にならないのみならずグリズリによる選り分け時に土砂や土がグリズリバーの間に挟まり目詰まりを生じる。このようになると、グリズリとしての粗篩いの効果が発揮できず砕石の生産が不可能となる。   In the rocks (raw stones) broken by blasting at the raw stone mountain, earth and sand and soil are naturally sandwiched between the stones (cracks). In particular, most of the fine particles having a size of 1 mm or less occupy dirt and soil impurities. If such earth and sand or soil is contained in a product (crushed stone), not only does it become a product, but also earth and sand and earth are caught between grizzly rivers during sorting by grizzly, resulting in clogging. If it becomes like this, the effect of the coarse sieving as grizzly cannot be exhibited, and the production of crushed stone becomes impossible.

このような不都合を防止し、除去するため数時間置きのグリズリバーの清掃を人力で行っているが、清掃作業場の真上には１トン以上の原石がフィーダ上に残っている場合が多く、極めて危険である。   In order to prevent and eliminate such inconvenience, the grizzly river is cleaned manually every few hours. However, there are many cases where over 1 ton of rough remains on the feeder just above the cleaning work place. It is a danger.

図８に示したのは、固定グリズリバー間に目詰まりが生じた状態を例示した拡大図である。   FIG. 8 is an enlarged view illustrating a state in which clogging occurs between the fixed grizzly rivers.

グリズリバーの目詰まりを除去しようとする構成は、下記文献に開示されている。
特開平５−１９２６４２号公報 グリズリ付振動フィーダ A configuration for removing clogging of the grizzly river is disclosed in the following document.
JP, 5-192642, A Vibration feeder with a grizzle

固定バーと可動バーとを交互に配列し、可動バーは一端を垂直軸回りにピン支持し、他端にストッパーを突設し、自転自在で進退動自在の連結棒に取付けた突片を前記ストッパーへ嵌装して可動バーを回動させる構成である。   The fixed bar and the movable bar are alternately arranged, and the movable bar has one end supported by a pin around the vertical axis, the other end is provided with a stopper, and the projecting piece attached to a connecting rod that is capable of rotating and reciprocating is provided. The movable bar is rotated by being fitted to the stopper.

この構成は可動バーを水平方向へ動かすものであり、固定バーと可動バーとの間に土砂や土、小塊が挟まった時、隣接するバーにも土砂や土、小塊が付着して折れば、可動バーを水平方向へ移動させることができず、また移動が可能であっても付着した泥土がバーと共に移動してしまい付着状態を除去できない場合が想定される。

特開平５−１８５０３４号公報 グリズリ付振動フィーダ In this configuration, the movable bar is moved in the horizontal direction. When earth, sand, or a small lump is sandwiched between the fixed bar and the movable bar, the adjacent bar is also broken by the earth, sand, or soil. For example, it is assumed that the movable bar cannot be moved in the horizontal direction, and even if the movable bar can be moved, the attached mud moves with the bar and the attached state cannot be removed.

Patent Document 1: Japanese Patent Laid-Open No. 5-185034 Grinding vibration feeder

一端をピン支持して水平方向回動自在な可動バーと可動フレームに固設した固定バーとを交互に配列した構成を示している。しかし、この文献は可動バーが水平方向に移動し且つ自由端部にスプリングを設けたものであり、本願とは構成を異にする。
特開平９−８５１７３号公報 振動ふるい分け装置 A configuration is shown in which a movable bar that supports one end with a pin and is rotatable in a horizontal direction and a fixed bar fixed to the movable frame are alternately arranged. However, in this document, the movable bar moves in the horizontal direction and a spring is provided at the free end, and the configuration is different from that of the present application.
JP, 9-85173, A Vibration sieving device

複数段に設置したスクリーンで、多数のグリズリバーの上流側を固定し、下流側を開放して櫛状グリズリバーユニットを設け、固定部に振動を生じさせるよう弾性シート、弾性ホルダーを設け粘土等の微細粒子を除去する装置を開示している。   With multiple screens installed, the upstream side of many grizzly rivers is fixed, the downstream side is opened to provide a comb-shaped grizzled river unit, and elastic sheets and elastic holders are provided to generate vibration in the fixed part. An apparatus for removing fine particles is disclosed.

しかし、この文献はグリズリバーの上端の固定部に弾性体を用いて振動させており、本願とは構成を異にする。   However, this document uses an elastic body to vibrate the fixed portion at the upper end of the grizzly river, and has a different configuration from the present application.

解決しようとする問題点は、固定グリズリバーと可動グリズリバーとが交互に配設されたグリズリにおいて、バー間に挟まり付着した土砂や土、小塊その他泥土等を確実に除去できなかった点である。   The problem to be solved is that in the grizzly structure in which the fixed grizzly river and the movable grizzly river are alternately arranged, the earth and sand, soil, small lump, and other mud soil stuck between the bars cannot be removed reliably.

従来のグリズリでは、固定グリズリバーに振動を与えて岩石を転がり落とすようにするか、また可動グリズリバーを有する装置では、等間隔に配設された多数のグリズリバーの間隔を変動することにより挟まった岩石を下方へ落下させたりしていた。   In conventional grizzly rocks, rocks are rolled down by applying vibration to fixed grizzly rivers, or in a device having movable grizzly rivers, rocks sandwiched by varying the intervals of a large number of grizzly rivers arranged at equal intervals. It was dropping down.

しかし、グリズリバー間に付着又は詰まった土砂や土等はグリズリバーの弾力的な振動では取除くことができず、また可動グリズリバーが水平方向へ移動する場合には等間隔を原則とするグリズリバーによる篩の作用に支障をきたすことになる。また可動グリズリバーが移動できない場合もあった。   However, dirt and soil adhered or clogged between the grizzly rivers cannot be removed by the elastic vibration of the grizzly rivers. It will interfere with the action. In some cases, the movable grizzly river could not move.

本発明は上記の課題解決のため、可動グリズリバーを支持アーム端部に設けた取付軸の垂直方向及びグリズリによる岩石の進行方向に平行な前後運動を加えることにより、確実に土砂や土、小塊等を除去しようとするものである。   In order to solve the above-mentioned problems, the present invention reliably applies earth and sand, earth, and small lump by applying a back-and-forth movement parallel to the vertical direction of the mounting shaft provided with the movable grizzly bar at the end of the support arm and the traveling direction of the rock by the grizzly. Etc. are to be removed.

第１発明は岩盤を崩してできた土砂や土を含む原石を、等間隔に配列され下方へ傾斜した複数のグリズリバー上を通過させて岩石の粗い選別又はクラッシャーへ送って砕石するグリズリ装置において、等間隔で多数並列して取付けられた固定グリズリバーと可動グリズリバーとを配設し、固定グリズリバーは固定フレームに上端を固定され、可動グリズリバーは固定フレームに一端を軸支した支持アームの他端に設けた取付軸に固定基部を固定し、他端を開放して取付けられ、駆動源から減速伝達されて回転する出力軸と偏心軸とを設け、この偏心軸が回転して生じる回転移動距離に応じて、前記支持アームの他端に設けた取付軸を介して可動グリズリバーが支持アームの回動円周沿いに前進後退の往復運動をするようにしたグリズリ装置とした。   The first invention is a grizzly device for crushing a rough stone containing earth and sand or soil formed by breaking a rock mass by passing it over a plurality of grizzly rivers arranged at equal intervals and inclined downward, and sending them to a coarse rock sorting or crusher. A fixed grizzly river and a movable grizzly river, which are mounted in parallel at equal intervals, are arranged. The fixed grizzly river is fixed at the upper end to the fixed frame, and the movable grizzly river is provided at the other end of the support arm that pivotally supports one end of the fixed frame. A fixed base is fixed to the mounting shaft, the other end is opened, and an output shaft and an eccentric shaft that are rotated by transmission of deceleration from the drive source are provided. Depending on the rotational movement distance that occurs when this eccentric shaft rotates. A movable grizzly bar that reciprocates forward and backward along the rotation circumference of the support arm via a mounting shaft provided at the other end of the support arm; It was.

第２発明では、取付軸が前進後退する往復運動手段として、固定フレームに一端を軸支され、他端に取付軸を有する支持アームと、駆動源から減速伝達されて回転する偏心軸に連結された連結アームとからなる略Ｌ字型アームを形成し、偏心軸の回転移動が取付軸の前進後退の往復運動となって可動グリズリバーが支持アームの回動円周沿いに前進後退の往復運動をするようにしたグリズリ装置とした。   In the second invention, as a reciprocating means for moving the mounting shaft forward and backward, it is connected to a support arm having one end pivotally supported by the fixed frame and having the mounting shaft at the other end, and an eccentric shaft that rotates by being decelerated from the drive source. A substantially L-shaped arm consisting of a connecting arm is formed, and the rotational movement of the eccentric shaft becomes the reciprocating motion of the mounting shaft, and the movable grizzly river performs the reciprocating motion of the supporting arm forward and backward along the rotation circumference of the support arm. It was set as the grizzly apparatus made to do.

第３発明では、下方へ傾斜した可動グリズリバーの上端基部が、取付軸の外周に固定基部を介して固定されると共に下端を自由端とし、可動グリズリバー基部の上方を防御鉄板で保護したグリズリ装置とした。   In the third invention, the upper end base portion of the movable grizzly river inclined downward is fixed to the outer periphery of the mounting shaft via the fixed base portion, the lower end is a free end, and the grizzly device with the upper side of the movable grizzly river base protected by a protective iron plate, did.

第４発明では、可動グリズリバーの長さが固定グリズリバーより短く、且つ先細に形成したグリズリ装置とした。
（作用） In 4th invention, it was set as the grizzly apparatus which the length of the movable grizzly river was shorter than the fixed grizzly river, and was tapered.
(Function)

第１発明では、出力軸とは偏心した偏心軸の回転移動距離に応じて、支持アームの他端に設けた取付軸を介して可動グリズリバーが移動するようにした。   In the first aspect of the invention, the movable grizzly river is moved through the mounting shaft provided at the other end of the support arm in accordance with the rotational movement distance of the eccentric shaft that is eccentric from the output shaft.

従って、可動グリズリバーは支持アームの回動円周沿いに前進後退の往復運動をするようになり、グリズリバー間に挟まった石及び土砂や土などが完全に除去又は下方へ落下するようになった。   Therefore, the movable grizzly river reciprocates forward and backward along the rotation circumference of the support arm, and stones, earth and sand, and soil sandwiched between the grizzly rivers are completely removed or fall downward.

第２発明では、固定フレームに一端を軸支され他端に取付軸を有する支持アームと、駆動源から減速伝達されて回転する偏心軸に連結された連結アームとからなる略Ｌ字型アームを形成したので、偏心軸の回転移動が取付軸に強力に伝達され、可動グリズリバーが支持アームの回動円周沿いに前進後退の往復運動をするようになった。   In the second invention, a substantially L-shaped arm comprising a support arm having one end pivotally supported by a fixed frame and having an attachment shaft at the other end, and a connecting arm coupled to an eccentric shaft that is rotated by being decelerated from a drive source. As a result, the rotational movement of the eccentric shaft is strongly transmitted to the mounting shaft, and the movable grizzly river reciprocates forward and backward along the rotation circumference of the support arm.

第３発明では、下方へ傾斜した可動グリズリバーの上端基部が、取付軸の外周に固定基部を介して固定され、取付軸と一体的に移動することになり、下端を自由端として可動が容易になったので、土砂や土などの付着を防止している。   In the third invention, the upper end base portion of the movable grizzly river inclined downward is fixed to the outer periphery of the mounting shaft via the fixed base portion, and moves integrally with the mounting shaft, and is easily movable with the lower end as a free end. As it became, we prevent adhesion of earth and sand or soil.

可動グリズリバー基部の上方は、岩石の落下から固定基部を覆う防御鉄板で保護した。   The upper part of the movable grizzly river base was protected by a protective iron plate covering the fixed base from falling rocks.

第４発明では、可動グリズリバーの長さが固定グリズリバーより短く、且つ先細に形成したことにより、傾斜するグリズリバーの下端部で詰まり易い土砂や土を長さの違うグリズリバーにより防止することができるようになった。   In the fourth invention, the length of the movable grizzly river is shorter than that of the fixed grizzly river and is tapered, so that it is possible to prevent earth and sand and soil that are easily clogged at the lower end portion of the inclined grizzly river by the grizzly river having different lengths. became.

本発明では、交互に配設された固定グリズリバーと可動グリズリバーの内、可動グリズリバーが支持アームの端部に設けた取付軸が回動円周上で前進後退運動をすることにより、付着したり挟まっている土砂や土等を一旦は押し上げ、前方へ押し出し後退する動作を繰り返すことにより、グリズリバーから確実に剥離できるようになった。   In the present invention, among the fixed and movable grizzly rivers arranged alternately, the mounting shaft provided at the end of the support arm of the movable grizzly river is attached or pinched by moving forward and backward on the rotation circumference. By repeatedly pushing up the earth, sand, etc., and then pushing it back and moving it back, it can be reliably peeled off from the grizzly river.

本発明は岩盤を崩してできた土砂や土を含む原石を、等間隔に配列され下方へ傾斜した複数のグリズリバー上を通過させて岩石の粗い選別又はクラッシャーへ送って砕石するグリズリ装置であり、等間隔で多数並列して取付けられた固定グリズリバーと可動グリズリバーとからなる。可動グリズリバーはパワーシリンダの往復動により、垂直方向と前後方向に独特な反復動をするので、グリズリバー間に付着又は挟まった原石及び土砂や土を確実に除去するものである。
以下、実施例につき説明する。 The present invention is a grizzly device for crushing a rough stone containing earth and sand and soil made by breaking the rock mass, passing through a plurality of grizzly bars arranged at equal intervals and inclined downward, and sent to a coarse rock sorting or crusher. It consists of a fixed grizzly river and a movable grizzly river that are mounted in parallel at equal intervals. The movable grizzly river repetitively moves in the vertical direction and the front-rear direction by the reciprocating motion of the power cylinder, so that the rough stone, earth and sand, and soil adhering or sandwiched between the grizzly rivers are surely removed.
Hereinafter, examples will be described.

図１は、グリズリ装置の平面図であり、図２は側面図である。   FIG. 1 is a plan view of the grizzly device, and FIG. 2 is a side view.

１は可動グリズリバーで、上端を固定基部２により取付軸３に固定し、他端は自由端となっている。４は固定グリズリバーで、固定フレームに上端を固定されている。   Reference numeral 1 denotes a movable grizzly river, the upper end of which is fixed to the mounting shaft 3 by the fixed base 2, and the other end is a free end. Reference numeral 4 denotes a fixed grizzly river whose upper end is fixed to a fixed frame.

可動グリズリバー１は固定グリズリバー４の間でそれぞれ等間隔に配列され、可動グリズリバー１と固定グリズリバー４とは交互に配設されている。グリズリの傾斜は通常３５〜３０度としている。   The movable grizzly rivers 1 are arranged at equal intervals between the fixed grizzly rivers 4, and the movable grizzly rivers 1 and the fixed grizzled rivers 4 are alternately arranged. The inclination of grizzly is usually 35 to 30 degrees.

図１において、可動グリズリバー１は固定基部２で取付軸３に固定され、取付軸３の回転揺動により駆動される。取付軸３は、電動機１３、減速機１２により回転するプーリ１０から伝動部１１を経てプーリ１０に回転を伝え、出力軸９を回転させる。   In FIG. 1, a movable grizzly river 1 is fixed to an attachment shaft 3 by a fixed base 2, and is driven by rotation and swinging of the attachment shaft 3. The attachment shaft 3 transmits rotation from the pulley 10 rotated by the electric motor 13 and the speed reducer 12 to the pulley 10 via the transmission unit 11 to rotate the output shaft 9.

出力軸９はプーリ１０と同一軸心であるが、偏心軸８はこの出力軸９の軸心に対して偏心している。偏心軸８からは連結アーム７を介して連結部６により、偏心した回転を取付軸３へ伝えるようになっている。   The output shaft 9 is the same axis as the pulley 10, but the eccentric shaft 8 is eccentric with respect to the axis of the output shaft 9. An eccentric rotation is transmitted from the eccentric shaft 8 to the mounting shaft 3 by the connecting portion 6 via the connecting arm 7.

固定グリズリバー４は固定フレーム１４に固定されている(図２、図４参照)。   The fixed grizzly river 4 is fixed to a fixed frame 14 (see FIGS. 2 and 4).

図３は可動グリズリバーの拡大側面図で、取付軸３に固定基部２により可動グリズリバー１は取付けられ、他端は自由端となっている。取付軸３が支持アーム５(図６参照)により、偏心軸８の移動距離だけ変動することにより可動グリズリバー１は一旦上方へ上がり、次いで前方へ進行し（１a）、後方へ戻って再び上方へ上がる垂直運動を繰り返して行う。   FIG. 3 is an enlarged side view of the movable grizzly river. The movable grizzly river 1 is attached to the attachment shaft 3 by the fixed base 2, and the other end is a free end. When the mounting shaft 3 fluctuates by the moving distance of the eccentric shaft 8 by the support arm 5 (see FIG. 6), the movable grizzly river 1 once rises upward, then advances forward (1a), returns to the rear, and then upwards again. Repeat the vertical movement up.

従来のグリズリバーのように水平方向への移動とは異なり、垂直方向の回転、前進後退運動により粘りの強い粘土等が確実に剥離出来るようになった。
１５は防御鉄板で、可動グリズリバーの固定基部２の上方を保護する。 Unlike conventional grizzly rivers, unlike clay in the horizontal direction, it has become possible to reliably peel off clay that is highly viscous by rotating in the vertical direction and moving forward and backward.
15 is a defense iron plate and protects the upper part of the fixed base part 2 of a movable grizzly river.

図４は固定グリズリバー４を示す拡大図で、固定フレーム１４に固定され、下方端は支持部上に載置されている。取付軸３には係合しないようになっている。   FIG. 4 is an enlarged view showing the fixed grizzly river 4, which is fixed to the fixed frame 14, and the lower end is placed on the support portion. The mounting shaft 3 is not engaged.

図５において、偏心軸８からの連結アーム７が連結部６を介して支持アーム５と連結されている。１６はホッパーで、グリズリバーの間隙を通って落下した石や細粒分を集積するよう耐摩耗性の厚い鉄板を使用した。   In FIG. 5, the connecting arm 7 from the eccentric shaft 8 is connected to the support arm 5 via the connecting portion 6. Reference numeral 16 denotes a hopper, which uses a thick wear-resistant iron plate to collect stones and fine particles that have fallen through the gaps in the grizzly river.

図６は可動グリズリバー１の移動状態を示す拡大説明図であり、支持アーム５、連結部６、連結アーム７は略Ｌ字型アームを形成している。可動グリズリバー１の先端は先細とし、固定グリズリバー４の長さより、短くしているので、グリズリバーの先端に粘着し易かった泥土が固まらず、除去作用が容易になった。   FIG. 6 is an enlarged explanatory view showing the moving state of the movable grizzly river 1, and the support arm 5, the connecting portion 6, and the connecting arm 7 form a substantially L-shaped arm. Since the tip of the movable grizzly river 1 is tapered and shorter than the length of the fixed grizzly river 4, the mud that easily adheres to the tip of the grizzly river does not solidify, and the removal action becomes easy.

図７は砕石の全体を示す一例である。原石山で発破により崩した岩石(原石)１８をダンプトラックにより運搬し原石ホッパー１９に投入され定量切出しフィーダに供給される。クラッシャーは原石を必要な大きさ(約に150mm)以下に破砕する。   FIG. 7 is an example showing the entire crushed stone. The rock (raw stone) 18 broken by blasting at the raw stone mountain is transported by a dump truck and is put into the raw stone hopper 19 and supplied to the fixed quantity cutting feeder. The crusher crushes the rough into the required size (about 150mm).

原石の大きさは直径１ｍから1ｍｍ以下の細粒分まですべて分布している。固定グリズリバー４は、石の進行方向に向かって下降傾斜しており、グリズリバーを転げ落ちた大きい岩石はクラッシャー１７に投入され、砕かれてベルトコンベヤ２１で運ばれ、集積される２３。グリズリバー４の間隙を抜けて落下した石はベルトコンベヤ２０で運ばれ集積される２２。   The size of the rough is distributed from 1 m to 1 mm in diameter. The fixed grizzly river 4 is inclined downward in the direction of the stone movement, and large rocks that have fallen down the grizzly river are put into the crusher 17, crushed, transported by the belt conveyor 21, and accumulated 23. Stones that have fallen through the gap between the grizzly rivers 4 are carried by the belt conveyor 20 and accumulated 22.

原石山の石の目(割れ目)には土砂や土が自然に挟まれており、発破で岩盤を崩せば当然それらも混ざってしまう。従って、１ｍｍ以下の細粒分には土砂や土の不純物がほとんどを占めており、固定グリズリバー４のみの場合、バーの間隙部に土砂や土が挟まり、クラッシャー１７に到る所で堆積し固化する危険が見られた。   Sediment and soil are naturally sandwiched between the stones (cracks) of the rough stone mountain, and naturally they will be mixed if the bedrock is destroyed by blasting. Therefore, the fine particles of 1 mm or less are mostly soil and soil impurities. In the case of the fixed grizzly river 4 alone, the sand and soil are sandwiched in the gaps between the bars and are deposited and solidified at the crusher 17. There was a danger to do.

図８は従来のグリズリバーによる石その他土砂や土、小塊２４の挟着状態を示す例である。雨天や雨上がり直後はグリズリが粘くなった土砂や土で塞がれてしまう。バーロッドは落ちないようにピン又はボルトナットで留めている。   FIG. 8 is an example showing a state in which stones, other earth and sand, earth, or a small lump 24 is sandwiched by a conventional grizzly river. Immediately after raining or after raining, the grizzly will be clogged with earth and sand. The bar rod is fastened with pins or bolts and nuts so as not to fall.

バーロッドの直径は７５から１００ｍｍ、長さが１から２ｍの鋼鉄製が多い。バー隙間は５０から１５０ｍｍでさまざまである。   Bar rods are often made of steel with a diameter of 75 to 100 mm and a length of 1 to 2 m. The bar gap varies from 50 to 150 mm.

バーロッドの他端はフリーになっている。バー間に石が挟まった場合、片方がフリーであれば掃除しやすい。下方のベースフレームが邪魔をして石の流れを止めやすい。下端部に一番石が止まり易い。ここに土砂や土、小塊２４が詰まれば、グリズリバーを下降する土砂や土等が順次積み重なり、最後には隙間がなくなる。水平方向に移動する従来のグリズリバーでは、これらを除去できなかった。   The other end of the bar rod is free. When a stone is caught between bars, it is easy to clean if one is free. The lower base frame is obstructive and it is easy to stop the stone flow. The stone is most likely to stop at the lower end. If earth and sand, earth, or a small block 24 is clogged here, earth and earth or the like descending the grizzly river are sequentially stacked, and finally there is no gap. These cannot be removed by the conventional grizzly river that moves in the horizontal direction.

可動グリズリバーが駆動源より常時又は必要に応じて移動するので、グリズリの目詰まりが確実に解消され、篩い分けと砕石作業が円滑に実行でき、利用範囲は広く活用できる。   Since the movable grizzly river moves from the driving source at all times or as necessary, clogging of the grizzly is reliably eliminated, sieving and crushed stone operations can be performed smoothly, and the range of use can be widely utilized.
