Description

本発明は土砂中の石礫を除去するための回転式除礫装置に関する。   The present invention relates to a rotary degraver for removing stones and gravel in earth and sand.

土砂中に石礫があると、根菜系作物が変形して商品価値が著しく低下することになる、また収穫の邪魔になって作業効率が低下し、あるいは農機具を破損させて耕作を中断しなければならなくなる等の不具合を生じる。
このため、農作物の育成過程において、土砂中の石礫を除去することは重要な作業となっている。
特に、北海道の農地のように寒冷地の広大な土砂地で農作物を育てる場合、土砂中の深い位置に堆積している石礫が氷、凍土砂等の作用により少しずつ上層に押し上げられ、表面近傍の石礫を除去しても数年後にはまた新たな石礫が表面近傍に出現するようになるため、定期的に、土砂中の石礫を除去する作業が必要になっている。 If there are stones and gravel in the earth and sand, the root crops will be deformed and the product value will be significantly reduced, the harvest will be in the way and the work efficiency will be reduced, or the farm equipment will be damaged and the cultivation must be interrupted. This causes problems such as unavoidable.
For this reason, in the process of growing crops, it is an important task to remove gravel in the sediment.
In particular, when growing crops on vast earth and sand in cold regions such as farmland in Hokkaido, the stones and gravel deposited deep in the soil are pushed up to the upper layer by the action of ice, frozen soil, etc. Even if the nearby gravel is removed, new gravel will appear again near the surface in a few years. Therefore, it is necessary to periodically remove the gravel in the sediment.

北海道の広大な農耕地における石礫除去作業は、自走式車両に形成された専用の除礫装置により実施される。
石礫除去に用いられる除礫装置としては、例えばトラクタショベルのショベル部に篩と石礫搬送用コンベアとを組み合わせた装置であって、クローラ式またはタイヤ式の走行体の前部に掘削部を有する除礫搬送装置を備え、この除礫搬送装置は油圧シリンダにより進行方向に対して左右方向に揺動される平板状篩として機能するように形成されているものがある。この場合は、篩により土砂部分は下へ振り落とされ、分別された石礫はコンベアにより後方へ搬送されて石礫搬送用ダンプトラック等に積載され、耕作地の外部へ搬出される（特開2000-186342号公報）。
また、他の装置としては、バックホーの後部に上部旋回体と衝突しないように支持アームを張り出し、この支持アームの上に平板状篩を揺動自在に配置したものがあり、この場合には、平板状篩は左右方向又は前後方向のいずれか一方へ揺動可能に設定されている （特開平9-13422号公報）。
このような除礫装置（ストンローダー式除礫装置）を用いた石礫除去作業では、前記の掘削部を有する除礫搬送装置またはバックホー等の建設機械を用いて耕作地の表面を掘削し、篩を形成している網バケットに土砂を投入し、土砂を入れた網バケットを揺動して土砂をふるい落とし、網バケット内に残った石礫をダンプトラック等に積み込んで搬出する。 The debris removal work in the vast agricultural land in Hokkaido is carried out by a dedicated debris device formed in a self-propelled vehicle.
As a debris removal device used for stone debris removal, for example, it is a device combining a shovel part of a tractor excavator with a sieve and a gravel conveying conveyor, and an excavation part is provided in front of a crawler type or tire type traveling body. There is a debris transporting device that has a debris transporting device that is formed so as to function as a flat-plate sieve that is swung in the left-right direction with respect to the traveling direction by a hydraulic cylinder. In this case, the earth and sand part is shaken down by the sieve, and the separated stone gravel is conveyed backward by a conveyor, loaded on a gravel conveying dump truck, etc., and carried out of the cultivated land (Japanese Patent Laid-Open No. 2000-133867). 2000-186342).
In addition, as another device, there is a device in which a support arm is extended at the rear part of the backhoe so as not to collide with the upper swing body, and a flat screen sieve is arranged on the support arm so as to be swingable. The flat screen sieve is set so as to be swingable in either the left-right direction or the front-rear direction (Japanese Patent Laid-Open No. Hei 9-34222).
In the debris removal work using such a debris device (stone loader type debris device), the surface of the cultivated land is excavated using a debris transport device having the excavation part or a construction machine such as a backhoe, Sediment is put into a mesh bucket forming a sieve, the mesh bucket containing the soil is swung to remove the sediment, and the gravel remaining in the mesh bucket is loaded onto a dump truck and carried out.

また、コンクリートミキサー車のミキサー部分に、小さな排出孔が周面に多数穿設された選別用ドラム（回転式筒状篩）を配した選別作業車として形成されたものがある。この場合には、石礫が含まれている土砂が、選別用ドラムの中をドラムの回転に伴い周方向上方へ持ち上げられ重力により下方へ落ちて細分されながら、徐々に投入口から石礫の排出口まで軸方向へ移動し、土砂部分を周面の小さな排出孔から下方へ排出し、分別された石礫を石礫排出口から外部へ排出される（特開2003-53266号公報）。
この他に、農耕地ではなく鉄道のレールが敷設された道床の砕石礫を交換する際の砕石礫篩分け装置も、レール上の台車に積載された装置として形成されているものがある。この場合には、台車の進行方向に対して横向きにされた回転式筒状篩が、投入口を上に排出口を下になるように傾斜した状態で回転自在に取付けられたもので、この場合には、小さい砕石礫を回転式筒状篩の周面から下方へ排出し、その排出された小さい砕石礫をベルトコンベアで運搬車両に運び、他所に搬出可能にするようにしており、大きい砕石礫は傾斜した回転式筒状篩の下端からレールの側方に排出され、再度、枕木の間の砕石礫埋め戻し位置に埋め戻される（特開平3-217280号公報）。 Further, there is a concrete mixer truck formed as a sorting work vehicle in which a sorting drum (rotary cylindrical sieve) having a large number of small discharge holes formed on the peripheral surface is arranged in the mixer portion. In this case, the earth and sand containing stones and gravel is gradually lifted in the sorting drum as the drum rotates upward in the circumferential direction and falls downward due to gravity. It moves in the axial direction to the discharge port, discharges the earth and sand part downward from a small discharge hole on the peripheral surface, and the separated gravel is discharged to the outside from the gravel discharge port (Japanese Patent Laid-Open No. 2003-53266).
In addition to this, there is also a crushed stone gravel sieving device for exchanging crushed gravel on a roadbed on which railroad rails are laid instead of agricultural land, which is also formed as a device loaded on a carriage on the rails. In this case, the rotating cylindrical sieve that is oriented transversely to the traveling direction of the carriage is rotatably mounted in a state that it is inclined so that the inlet is on the top and the outlet is on the bottom. In this case, small crushed gravel is discharged downward from the peripheral surface of the rotary cylindrical sieve, and the discharged small crushed gravel is transported to a transport vehicle by a belt conveyor so that it can be transported to other places. The crushed stone gravel is discharged to the side of the rail from the lower end of the inclined rotary cylindrical sieve, and is backfilled again at the crushed stone gravel backfill position between sleepers (Japanese Patent Laid-Open No. 3-217280).

このような従来の石礫除去作業は、レールに沿って線状に移動することしかできない鉄道の場合を除き、除去する石礫の大きさを２５ｍｍ以上として、農耕地１ha（ヘクタール）当りの施工日数は約16日、総費用は２００万円程度となる。
このため、除去する石礫の大きさをより小さくするとともに、処理効率を高めて施工日数を短縮し、その結果として総経費をさらに低価格に下げることが望まれていた。 Such conventional gravel removal work, except for railways that can only move linearly along the rail, is a construction per 1 ha (a hectare) of agricultural land, with the size of the gravel to be removed being 25 mm or more The number of days is about 16, and the total cost is about 2 million yen.
For this reason, it has been desired to reduce the size of stones to be removed, to increase the processing efficiency and shorten the construction days, and as a result, to further reduce the total cost.

搬送は、トラック輸送されるから移動が速やかに行われ、キャタピラを有するクローラ形の走行車両に比較して、短時間で目的の場所に搬入することができて、除礫作業を早く開始することができ、費用及び時間を有効に利用することができるようになる。
回転部材１１は、篩支持部材２１と網目部材２２とが個別に着脱可能に形成されているから、各個に点検整備を行うことができ、部品交換も個別にできて、回転部材１１を最良の状態に容易に維持でき、装置寿命を長くするとともに点検整備交換等に係る費用を安価にすることができる。 In the case of using such a rotary debris device 10, the size of the debris 3 that can be degraved can be reduced to 20 mm or less than the conventional size, and the number of construction days per hectare is about 10 days. The cost is approximately 1,200,000 yen, and the schedule is greatly shortened and the cost can be reduced as compared with the conventional method.
Further, since this rotary debris device 10 can be loaded on a general-purpose truck 1, it is not necessary to provide a dedicated self-propelled device, and the manufacturing cost of the device can be low, and the cost related to degraving work can be reduced. Of these, the cost associated with the use of the rotary degraver 10 is also low.
Since transportation is carried out by truck, it moves quickly, and can be carried to the target place in a short time compared to a crawler-type traveling vehicle with a caterpillar, and degraving work can be started quickly. It is possible to effectively use the cost and time.
Since the rotating member 11 is formed so that the sieve support member 21 and the mesh member 22 can be individually attached and detached, each individual member can be inspected and serviced, and parts can be replaced individually. It can be easily maintained in a state, and the life of the apparatus can be extended and the cost for inspection and maintenance can be reduced.

〔第２実施態様の作用効果〕
このような第２実施態様の回転式除礫装置５０では、第１実施態様における回転式除礫装置１０の作用効果の他に、回転部材５１を形成する支持部材５１ａと網目部材５１ｂと各固定部材５１ｃ，５１ｄ，５１ｅとを、上端を開口した周縁部に低いフランジを有する箱型の部材に形成したことにより、隣接する各部材を着脱自在に固着することによって、回転部材５１が剛性の高い筒型の部材を形成することができ、内部には何も支持部材のない容量の大きな中空部を形成することができる。
また、基台部材５６に対して支持部材５１ａと網目部材５１ｂと各固定部材５１ｃ，５１ｄ，５１ｅとを隣接する各部材を個々に固着することによって、容易に回転式除礫装置５０を組み上げることができ、分解・組立が容易で、使用時および収納・保管時における作業が容易になるとともに短時間で済むようになる。 [Effects of Second Embodiment]
In such a rotary degraver 50 according to the second embodiment, in addition to the operational effects of the rotary degraver 10 according to the first embodiment, the support member 51a and the mesh member 51b that form the rotary member 51 and the fixed members are fixed. By forming the members 51c, 51d, and 51e into box-shaped members having a low flange at the peripheral edge with the upper end opened, the rotating member 51 has high rigidity by detachably fixing adjacent members. A cylindrical member can be formed, and a large-capacity hollow portion without any support member can be formed inside.
In addition, the rotary degraver 50 can be easily assembled by fixing the supporting member 51a, the mesh member 51b, and the fixing members 51c, 51d, and 51e to the base member 56 by adhering the adjacent members individually. It is easy to disassemble and assemble, and the work at the time of use, storage and storage is facilitated and the time can be shortened.

回転式除礫装置５０の回転部材５１を中空に形成するとともに内部には回転部材５１の内面に付着している土砂を掻き落とすドロ落とし装置５７を内設したことにより、常時、ドロ落とし装置５７の先端部が回転部材５１の内面を擦り、内面に付着している土砂を掻き落として、土砂により篩部の網目が閉塞されないように掃除することができ、石礫の分別の処理効率が低下しないようにして、高い処理効率を維持することができる。
回転部材５１の内部にドロ落とし装置５７を設け、各ドロ落とし部材５７ｆの先端部を篩の網目に当接して、回転部材５１の回転に従って上昇すると、先端部に設けた錘５７ｇの重さを支えられなくなって落下するようにしたことにより、内面側から網目に付着した土砂を擦り落とすことができるようになり（図１８参照）、バックホー等の掘削機により掘削された土砂が水分を比較的多目に含んでいる場合でも、各ドロ落とし部材５７ｆの先端部が網目に付着した土砂とともに回転部材５１の回転方向へ共回りして回転していく時、ドロ落とし部材５７ｆの先端部が垂直に垂下された位置からある角度以上に回転すると、取付けられている錘５７ｇの重さと加えられた土砂の重さを支えきれなくなり、回転部材５１の当接箇所から下方に落ち込み、そのときの先端部の軌跡にしたがって回転部材５１の内面を掻き落として、篩の網目に付着した土砂を取り除き、網目の目詰まりを防止して石礫と土砂の分別を効率良く行うことができる。 Since the rotary member 51 of the rotary debris device 50 is formed in a hollow shape and the inside thereof is provided with a drop-off device 57 that scrapes off the sediment adhering to the inner surface of the rotary member 51, the drop-off device 57 is always provided. Can be cleaned so that the mesh of the sieving part is not blocked by the earth and sand by scraping the earth and sand adhering to the inner surface of the rotating member 51, and the processing efficiency for separating the gravel is reduced. In this way, high processing efficiency can be maintained.
When a dropping device 57 is provided inside the rotating member 51 and the tip of each dropping member 57f is brought into contact with the mesh of the sieve and is lifted as the rotating member 51 rotates, the weight of the weight 57g provided at the tip is increased. By falling so that it can no longer be supported, it becomes possible to scrape the earth and sand adhering to the mesh from the inner surface side (see FIG. 18), and the earth and sand excavated by an excavator such as a backhoe can relatively absorb moisture. Even if it is included in many, when the tip of each dropping member 57f rotates together with the earth and sand adhering to the mesh in the rotation direction of the rotating member 51, the tip of the dropping member 57f is vertical. If it rotates more than a certain angle from the position where it hangs down, it will not be able to support the weight of the attached weight 57g and the weight of the added earth and sand, and will fall downward from the contact point of the rotating member 51. And scraping the inner surface of the rotating member 51 in accordance with the trajectory of the tip at that time, removing earth and sand adhering to the mesh of the sieve, preventing clogging of the mesh and efficiently separating the gravel and earth and sand Can do.

また、ドロ落とし装置５７に設けたドロ落とし部材５７ｆは、多数の棒状に形成して、ドロ落とし支持部材５７ｂの全長にわたり２段に整列するように配置したことにより、回転部材５１の内面の状況に応じて個々のドロ落とし部材５７ｆがそれぞれの状況に応じて土砂を掻き落とすことができ、しかもその各ドロ落とし部材５７ｆに取付けられた錘５７ｇの重さに応じたドロ落としをするため、特別な動力が必要にならず、省エネ仕様のドロ落とし装置が実現できる。
さらにまた、投入側部材５２の底部に土砂送り装置５８を設けたことにより、湿り気の多い土砂が投入された場合でも、土砂送り装置５８の回転羽根５８ａが回転部材５１へ土砂を送り込む方向へ移動して、強制的に土砂を回転部材５１の中へ移送することができ、土砂と石礫との分離作業を確実に行うことができるようにする。 Further, the drop drop member 57f provided in the drop drop device 57 is formed in a number of rods and arranged so as to be aligned in two stages over the entire length of the drop drop support member 57b. Depending on the situation, each drop drop member 57f can scrape the earth and sand according to each situation, and the drop drop according to the weight of the weight 57g attached to each drop drop member 57f is special. Power is not required and an energy-saving dripping device can be realized.
Furthermore, by providing the earth and sand feeding device 58 at the bottom of the loading side member 52, even when moist sand is thrown in, the rotary blade 58a of the earth and sand feeding device 58 moves in the direction of feeding the earth and sand to the rotating member 51. Thus, the earth and sand can be forcibly transferred into the rotating member 51, and the separation work of the earth and sand and stones can be reliably performed.
