Description

本発明は帆立貝、牡蠣など、養殖貝の選別装置の改良に関する。 The present invention relates to an improvement of a sorting device for cultured shellfish such as scallops and oysters.

従来、養殖して生育させた帆立貝や牡蠣などの養殖貝を出荷するため、貝を大中小に分けるための選別作業が行われている。この選別作業は、養殖貝の破損を防止するため手作業で行うのが理想的であるが、作業効率の向上と労力の軽減を図るため機械による選別作業が主流となっている。 Conventionally, in order to ship cultured shellfish such as scallops and oysters that have been cultivated and grown, sorting operations for dividing shellfish into large, medium and small have been performed. This sorting operation is ideally performed manually in order to prevent the cultured shells from being damaged, but a machine sorting operation is mainly used in order to improve work efficiency and reduce labor.

従来から使用される養殖貝の選別装置は多種多様であるが、養殖貝を効率的に選別するため、それぞれ内径が相違する多数の孔を設けた篩板を上下に取付けた選別台の入口側を高く出口側を低く傾斜させて位置し、該選別台の上方に養殖貝を収容するホッパーを取付けて形成したものが広く使用されている。 There are various kinds of cultured shellfish sorting devices that have been used in the past, but in order to efficiently sort the cultured shellfish, the entrance side of the sorter with a sieve plate with a number of holes with different inner diameters attached vertically Is widely used, and is formed by attaching a hopper that accommodates cultured shellfish above the sorting table.

前記選別台は、駆動源からプーリーを介して駆動力を支持腕の一端に偏心させて軸支し、他端を枠体に枢動可能に軸支し、前記プーリーの回転による偏心運動で選別台を揺動させることにより篩板上の養殖貝を移動させながら所定大きさの孔からそれぞれ貝を落下させて選別する選別装置が知られている。 The sorting table is pivotally supported by eccentrically driving force from a driving source to one end of a support arm via a pulley, and the other end is pivotally supported by a frame, and is sorted by eccentric motion by rotation of the pulley. 2. Description of the Related Art A sorting device is known that moves and moves cultured shells on a sieve plate by swinging a table to drop shells from holes of a predetermined size.

前記した選別装置は、いずれも駆動源であるモータを選別台の下側に位置し、駆動源からの揺動手段を入口側に設け、出口側を選別装置の枠体に支持して形成してある。したがって、前記選別台の振動は、入口側が強く大きく振動し、出口側は基台に支持されているだけであるため小さく振動する。一方、選別される養殖貝は、大きさ、形状、表面に付着物があるものなど多様であることから、それぞれ養殖貝の摩擦抵抗が相違する。 Each of the above-described sorting devices is formed by positioning a motor as a driving source below the sorting table, providing swinging means from the driving source on the inlet side, and supporting the outlet side on the frame of the sorting device. It is. Therefore, the vibration of the sorting table vibrates greatly on the inlet side, and vibrates small because the outlet side is only supported by the base. On the other hand, the cultured shells to be selected vary in size, shape, and the presence of deposits on the surface, so the frictional resistance of the cultured shells is different.

そのため、選別台上を移動する養殖貝の移動速度が不揃いで一定しないため、養殖貝同士が重なりやすく所定の穴から落ちにくく、貝の選別を効果的に行うことが困難である。また、前記文献に示される選別台は、いずれも揺動させる駆動モータを選別台の下側に取付けてあるため、養殖貝に含まれる海水や養殖貝に付着した泥やごみを除去するために噴射する海水で作業のたびに駆動モータをはじめ伝導手段であるチェーンまたは軸受部などが海水に浸かった塩害により錆びたり腐食するのが早く長持ちしない。 Therefore, since the moving speeds of the cultured shells moving on the sorting table are not uniform and are not constant, the cultured shells easily overlap each other and are difficult to fall from a predetermined hole, and it is difficult to effectively select the shells. In addition, since the sorting tables shown in the above documents all have a swinging drive motor attached to the lower side of the sorting table, in order to remove the seawater contained in the cultured shellfish and mud and dirt attached to the cultured shellfish Each time you work with seawater that you spray, the chain or bearing, which is the drive means, including the drive motor, will not rust or corrode due to salt damage immersed in seawater.

また、前記選別装置は、前記したごとく、選別台の一端と揺動機構とを直接連結し、他端を枠体に支持してあることから選別台の揺動を均一化するために選別台の下側にばねなどを取付けて構造を複雑にしてある。さらには、選別台の揺動により養殖貝が孔に嵌ると、他の養殖貝の移動を邪魔し養殖貝の流れが悪くなり、且つ、多数の選別孔が塞がると小さな貝が選別されずに通過してしまい、選別効率が落ちる原因にもなる。また、孔に嵌まった養殖貝は、振動によりさらに強く嵌ってしまうため取り出し難く、無理に取り出すと養殖貝が欠けたり、割れたりして出荷する貝の歩留まりが悪くなるなどの問題点を有している。 In addition, as described above, the sorting device directly connects one end of the sorting table and the swing mechanism, and the other end is supported by the frame. The structure is complicated by attaching a spring or the like on the lower side. Furthermore, if the cultured shells fit into the holes due to the swinging of the sorting table, the movement of the other cultured shells will be disturbed, and the flow of the cultured shells will deteriorate, and if many sorting holes are blocked, the small shells will not be sorted. It will also pass and cause sorting efficiency to drop. In addition, cultured shells that fit into holes are more difficult to remove because they are more strongly fitted by vibrations, and if removed forcibly, the cultured shells may be chipped or cracked, resulting in poor yield of shipped shellfish. doing.

本発明が解決しようとする課題は、駆動源と揺動機構を基枠の上方に設けて塩害による故障を防止し、また、選別台全体を揺動機構により均一に揺動させることにより、移動する養殖貝の速さを緩やかにして養殖貝が常に水平移動して貝同士の衝突による傷付きを防止し、さらに養殖貝が選別孔に嵌まるのを防止すると共に、養殖貝の流れを良くして選別効率の向上を図り、且つ、選別台を揺動機構に着脱可能に取付けて選別台のメンテナンスを容易にすると共に、選別装置の構造の簡素化と組立工程、組立作業の効率化を図ることを目的とする。 The problem to be solved by the present invention is that a drive source and a swinging mechanism are provided above the base frame to prevent failure due to salt damage, and the entire sorting table is swung evenly by the swinging mechanism. Decrease the speed of the cultured shells so that the cultured shells always move horizontally to prevent damage caused by clashes between shells, and prevent the cultured shells from fitting into the sorting holes and improve the flow of the cultured shells. In addition to improving the sorting efficiency, the sorting table can be detachably attached to the swing mechanism to facilitate the maintenance of the sorting table, simplify the structure of the sorting device, and improve the efficiency of the assembly process and assembly work. The purpose is to plan.

The plate 17a and the first swing plate 25a are pivotally connected by a single connecting bolt 29, and the second holding plate 17b and the second swing plate 25b attached to the outlet side are connected by a plurality of connecting bolts 29. By connecting each other and connecting one of the sorting tables 10 (inlet side or outlet side) so as to be pivotable, even if the connecting portion such as the first drive source Ta or the transmission means U is displaced due to wear or the like, the displacement is caused. Therefore, the sorting table 10 can be swung smoothly at any time. Of course, the holding plate 17 and the swing plate 25 may be connected not only by the connecting bolt 29 but also by welding.

前記選別台１０は、図１〜６に示すごとく、長手方向の両端で並行に位置させた一対の棚枠部１１の内側に篩板を挿通する溝部１１ａ、１１ｂを上下方向に１から３段、好ましくは、２段に形成し、上側溝部１１ａに中型以下の養殖貝Ｈが落下する内径を有する多数の孔１４を有した第１篩板１３を挿通し、下方の溝部１１ｂに小型の養殖貝Ｈが落下する内径を有する多数の孔１６を有した第２篩板１５を挿通し、前記棚枠部１１の上方に設けた枠板１２上に多数の養殖貝Ｈを収納するホッパー３１の支持脚部３２を取付け、前記棚枠部１１の外壁面長手方向両側の四角にそれぞれ保持板１７を取付けてある。したがって、前記ホッパー３１は、選別台１０と共に揺動可能に取付けてある。 As shown in FIGS. 1 to 6, the sorting table 10 has groove portions 11 a and 11 b through which a sieve plate is inserted inside a pair of shelf frame portions 11 that are positioned in parallel at both ends in the longitudinal direction. Preferably, the first sieve plate 13 having a plurality of holes 14 having an inner diameter through which the middle-sized or smaller cultured shell H falls is inserted into the upper groove portion 11a, and a small size is inserted into the lower groove portion 11b. A hopper 31 for inserting a large number of cultured shells H on a frame plate 12 provided above the shelf frame 11 is inserted through a second sieve plate 15 having a large number of holes 16 having an inner diameter through which the cultured shells H fall. The support legs 32 are attached, and the holding plates 17 are attached to the squares on both sides in the longitudinal direction of the outer wall surface of the shelf frame 11.

A check window 18 that also serves as a stopper is attached so as to be openable and closable, and the cultured shell H is smoothly discharged to the lower surface on the inlet side and the lower surface on the outlet side of the sorting table 10 and the outlet side of the sieve plates 13 and 15 of each stage. Guide shooters 37a, 37b, and 37c are attached respectively.

選別台１０の入口ホッパー３５内に落下した養殖貝Ｈは、図２、９に示すごとく、選別台１０が入口方向から出口方向に傾斜していること、および第１揺動機構Ｓａにより選別台１０を水平方向の往復動と上下動からなる揺動運動をさせることにより、篩板１３、１５上の養殖貝Ｈが篩板に押付けられて水平方向に移動した位置で留まり、次いで篩板が後退し、さらに篩板が押し上げられる動作を繰返しながら出口方向に移動し、養殖貝Ｈは第１、２篩板１３、１５に設けた大きさに合致した孔１４、１６からそれぞれ落下することにより篩い分けられて排出可能に形成してある。 As shown in FIGS. 2 and 9, the cultured shellfish H that has fallen into the inlet hopper 35 of the sorting table 10 has the sorting table 10 tilted from the inlet direction to the outlet direction, and the sorting table by the first swing mechanism Sa. 10 is moved in a horizontal direction by reciprocating and moving up and down in the horizontal direction so that the cultured shell H on the sieve plates 13 and 15 is pressed against the sieve plate and stays in the horizontal position. It moves backward in the direction of the exit while retreating, and the screen plate is further pushed up, and the cultured shellfish H falls by falling from the holes 14 and 16 that match the size provided in the first and second screen plates 13 and 15, respectively. It is formed by sieving so that it can be discharged.

前記選別台１０に取付けた各ガイドシューター３７は、選別された養殖貝Ｈが所定の落下地点に用意した収容容器４０に落ちるようにガイドし、落下地点にそれぞれ配置した収容容器４０内に前記養殖貝Ｈが傷付くことなく効率よく回収することができる。 Each guide shooter 37 attached to the sorting table 10 guides the sorted cultured shellfish H to fall into the containing container 40 prepared at a predetermined dropping point, and the aquaculture is placed in the containing container 40 respectively arranged at the dropping point. The shell H can be efficiently recovered without being damaged.

Good. Further, the cultured shellfish H sent to the sorting device 1 may be placed not only on the hopper 31 of the sorting table 10 but also directly conveyed to the inlet hopper 35 by a belt conveyor for sorting work.

本発明の第２の実施の形態に係る選別装置１ｂの実施の形態を図面に基づいて説明すると、図１０は第２揺動機構を取付けた選別装置の平面図、図１１は第２揺動機構に選別台を懸架した状態の要部拡大断面図、図１２は第２揺動機構の偏心円盤に軸支した揺動板の偏心回転を示す要部拡大断面図である。選別装置１ｂは、長手方向を傾斜させて形成した基枠２の上方に設けた支持枠部５の左右両側で並行に軸支した一対の伝動軸２０にそれぞれ連結した一対のモータ６ｂと駆動軸７ｂと減速機９ｂとからなる第２駆動源Ｔｂと、前記一対の伝動軸２０の両端にそれぞれ取付けた第２揺動機構Ｓｂと、該第２揺動機構の下方に養殖貝Ｈを選別するための孔１４を多数設けた少なくとも１以上の篩板１３を上下方向に位置してなる選別台１０を揺動可能に懸架してある。 An embodiment of a sorting apparatus 1b according to the second embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a plan view of a sorting apparatus equipped with a second swing mechanism, and FIG. FIG. 12 is an enlarged cross-sectional view of the main part showing the eccentric rotation of the swinging plate pivotally supported by the eccentric disk of the second swinging mechanism. The sorting device 1b includes a pair of motors 6b and a drive shaft respectively coupled to a pair of transmission shafts 20 that are pivotally supported in parallel on the left and right sides of the support frame portion 5 provided above the base frame 2 formed with the longitudinal direction inclined. A second drive source Tb composed of 7b and a speed reducer 9b, a second swinging mechanism Sb attached to both ends of the pair of transmission shafts 20, and the cultured shellfish H are selected below the second swinging mechanism. A sorting table 10 in which at least one sieve plate 13 provided with a large number of holes 14 is positioned in the vertical direction is suspended so as to be swingable.

前記第２駆動源Ｔｂは、モータ６ｂから減速機９ｂまたはインバータを介して駆動軸７ｂの回転数を制御し、該駆動軸の先端と前記支持枠部５の左右両端で並行に位置した一対の伝動軸２０の一端にそれぞれ軸着した第２揺動機構Ｓｂの突出軸５３とを接続器（図示せず）を介して連結してある。 The second drive source Tb controls the rotational speed of the drive shaft 7b from the motor 6b via the speed reducer 9b or an inverter, and a pair of the drive shaft Tb and the pair of support frames 5 positioned in parallel at the left and right ends of the support frame portion 5. The projecting shafts 53 of the second oscillating mechanism Sb that are respectively attached to one end of the transmission shaft 20 are connected via a connector (not shown).

前記選別台１０は第１の実施の形態に示す選別装置１ａと同じであることから、ここで説明すると内容が重複することから説明を省略する。 Since the sorting table 10 is the same as the sorting apparatus 1a shown in the first embodiment, the description thereof will be omitted because the contents are duplicated here.

第２揺動機構Ｓｂは、図１０、１１に示すごとく、大径な偏心円盤５１の外周面に揺動板５５を回動可能に取付け、該偏心円盤５１の軸心方向と偏心位置に設けた軸止部５２に前記一対の伝動軸２０の端部をそれぞれ軸着し、該伝動軸の片側に位置した偏心円盤５１ａの軸止部５２から伝動軸２０の端部を貫通させて突出軸５３を設け、該突出部の一端と前記第２駆動源Ｔｂの先端とを連結し、前記揺動板５５の下方と選別台１０に取付けた保持板１７の上方とを連結して第２揺動機構Ｓｂに選別台１０を揺動可能に懸架してある。 As shown in FIGS. 10 and 11, the second swing mechanism Sb is attached to the outer peripheral surface of the large-diameter eccentric disk 51 so as to be rotatable, and is provided in the axial direction and the eccentric position of the eccentric disk 51. The end portions of the pair of transmission shafts 20 are respectively attached to the shaft stop portions 52, and projecting shafts are formed through the end portions of the transmission shaft 20 from the shaft stop portions 52 of the eccentric disk 51a located on one side of the transmission shaft. 53, one end of the projecting portion and the tip of the second drive source Tb are connected, and the lower portion of the swing plate 55 and the upper portion of the holding plate 17 attached to the sorting table 10 are connected to each other. The sorting table 10 is swingably suspended on the moving mechanism Sb.

前記一対の伝動軸２０の一端にそれぞれ第２駆動源Ｔｂを連結したことにより、該第２駆動源に加わる負荷が軽減されるため、回転力をスムースに第２揺動機構Ｓｂに伝達し、スムースに偏心運動に変換させて選別台１０を水平方向の往復動と上下動からなる揺動運動を可能にすることができる。 Since the load applied to the second drive source is reduced by connecting the second drive source Tb to one end of the pair of transmission shafts 20, the rotational force is smoothly transmitted to the second swing mechanism Sb. By smoothly converting to an eccentric motion, the sorting table 10 can be made to swing in a horizontal reciprocating motion and a vertical motion.

さらには、図１１に示すごとく、前記選別台１０に設けた各保持板１７と、前記２揺動機構Ｓｂに取付けた揺動板５５との連結は、入口側の第１保持板１７ａと第２揺動板５５ａとを単数の連結ボルト２９で枢動可能に連結し、出口側の第２保持板１７ｂと第２揺動板５５ｂとを複数の連結ボルト２９で連結したことにより、選別台１０の揺動をスムースに行うことができる。前記保持板１７と揺動板５５との連結は、連結ボルト２９だけでなく溶着による固定でもよいことは勿論である。 Furthermore, as shown in FIG. 11, each holding plate 17 provided on the sorting table 10 and the swing plate 55 attached to the second swing mechanism Sb are connected to the first holding plate 17a on the inlet side and the first support plate 17a. The second swing plate 55a is pivotally connected by a single connection bolt 29, and the second holding plate 17b on the outlet side and the second swing plate 55b are connected by a plurality of connection bolts 29, so that a sorting table is obtained. 10 swings can be performed smoothly. Of course, the holding plate 17 and the swing plate 55 may be connected not only by the connecting bolt 29 but also by welding.

以下、第１揺動機構Ｓａを取付けた選別装置１ａの作用について説明すると、第１駆動源Ｔａを基枠２の上方に設けた支持枠部５の中央に位置し、前記支持枠部５の両側に取付けた第１揺動機構Ｓａの揺動板２５に養殖貝Ｈを選別する選別台１０を連結ボルト２９で着脱可能に懸架し、前記第１駆動源Ｔａおよび第１揺動機構Ｓａを基枠２の上方に位置したことにより、選別作業において選別台１０の養殖貝Ｈに噴射する海水に濡れることが少ないので塩害による腐食や錆びによる不具合を防止することができ、機器を長持ちさせることができる。 Hereinafter, the operation of the sorting device 1a to which the first swing mechanism Sa is attached will be described. The first drive source Ta is located at the center of the support frame portion 5 provided above the base frame 2, and the support frame portion 5 A sorting table 10 for sorting the cultured shellfish H is detachably suspended by connecting bolts 29 on the swing plate 25 of the first swing mechanism Sa attached to both sides, and the first drive source Ta and the first swing mechanism Sa are connected to each other. Because it is located above the base frame 2, it is less likely to get wet by the seawater sprayed to the cultured shell H of the sorting table 10 in the sorting operation, so that it is possible to prevent corrosion and rust caused by salt damage and to make the equipment last longer. Can do.

また、第１揺動機構Ｓａを構成する揺動板２５に選別台１０の保持板１７を着脱可能に連結して懸架したことにより、第１揺動機構Ｓａと選別台１０との連結構造が簡単で部品数が少なくコストが安価で経済的であると共に、揺動運動をスムースに行うことができるので養殖貝Ｈの選別効率を向上させることができる。 Further, since the holding plate 17 of the sorting table 10 is detachably connected to the swing plate 25 constituting the first swing mechanism Sa and suspended, the connection structure of the first swing mechanism Sa and the sorting table 10 is obtained. It is simple, has a small number of parts, is inexpensive, and is economical, and the swinging motion can be smoothly performed, so that the sorting efficiency of the cultured shellfish H can be improved.

前記第１揺動機構Ｓａの揺動板２５と、選別台１０の保持板１７との連結は、入口側の揺動板２５ａと保持板１７ａを一本の連結ボルト２９で枢動可能に連結し、出口側の揺動板２５ｂと保持板１７ｂを２本の連結ボルト２９で固定して懸架することにより、第１駆動源Ｔａまたは伝動手段Ｕなどの摩耗等によってズレが生じた場合でも、連結部分の一方を枢動可能に連結したことにより、ズレを吸収することができるので、選別台１０をいつでもスムースに揺動させることができる。前記連結ボルト２９による連結は、入口側を２本のボルトで固定し出口側を一本のボルトで枢動可能に連結してもよい。 The swing plate 25 of the first swing mechanism Sa and the holding plate 17 of the sorting table 10 are connected to each other so that the swing plate 25a on the inlet side and the holding plate 17a can be pivoted by a single connecting bolt 29. Even if the first drive source Ta or the transmission means U is worn away by fixing the suspension plate 25b on the outlet side and the holding plate 17b with the two connecting bolts 29 and suspending them, By connecting one of the connecting portions so as to be pivotable, it is possible to absorb the deviation, and thus the sorting table 10 can be smoothly swung at any time. The connection by the connecting bolt 29 may be such that the inlet side is fixed with two bolts and the outlet side is pivotally connected with one bolt.

さらには、第１揺動機構Ｓａと選別台１０とを連結ボルト２９で着脱可能に連結したことにより、選別台１０を簡単に脱着することができるので、選別台１０の掃除やメンテナンスを容易に行うことができるので選別装置１ａを長持ちさせることができる。 Furthermore, since the first swing mechanism Sa and the sorting table 10 are detachably connected by the connecting bolt 29, the sorting table 10 can be easily detached, so that the sorting table 10 can be easily cleaned and maintained. Since it can be performed, the sorting apparatus 1a can be made long lasting.

第２揺動機構Ｓｂを取付けた選別装置１ｂは、大径な偏心円盤５１の外周面に揺動板５５を回動可能に軸支し、該偏心円盤５１の軸心方向で偏心位置に設けた軸止部５２に前記一対の伝動軸２０の端部をそれぞれ軸着し、該伝動軸の片側に位置した偏心円盤５１ａの軸止部５２から伝動軸２０の端部を貫通させた突出軸５３の一端と、前記第２駆動源Ｔｂの駆動軸７ｂに取付けた減速機９ｂを介して連結し、前記揺動板５５の下方と、選別台１０に取付けた保持板１７の上方とを連結して第２揺動機構Ｓｂに選別台を１０揺動可能に懸架してある。 The sorting device 1b to which the second oscillating mechanism Sb is attached has an oscillating plate 55 pivotally supported on the outer peripheral surface of the large-diameter eccentric disc 51 and is provided at an eccentric position in the axial direction of the eccentric disc 51. Projection shafts in which the end portions of the pair of transmission shafts 20 are respectively attached to the shaft stop portions 52, and the end portions of the transmission shaft 20 are penetrated from the shaft stop portions 52 of the eccentric disk 51a located on one side of the transmission shafts. One end of 53 is connected via a speed reducer 9b attached to the drive shaft 7b of the second drive source Tb, and the lower part of the swing plate 55 and the upper part of the holding plate 17 attached to the sorting table 10 are connected. Thus, the sorting table is suspended on the second swing mechanism Sb so as to be able to swing 10 times.

したがって、基枠２の上方に設けた支持枠部５の左右両側に軸支した伝動軸２０の一端にそれぞれ第２駆動源Ｔｂを取付けたことにより、モータ６ｂの負荷を少なくすることができるので、装置の故障を防止することができる。また、伝動軸２０の両端に第２揺動機構Ｓｂを取付け、偏心円盤５１に揺動板５５を回転可能に取付けたこと、さらに、第２揺動機構Ｓｂと選別台１０との連結を、片側を一点支持の枢動可能に連結したことにより、選別台１０の揺動をスムースに行うことができる。 Accordingly, the load on the motor 6b can be reduced by attaching the second drive source Tb to one end of the transmission shaft 20 pivotally supported on both the left and right sides of the support frame portion 5 provided above the base frame 2, respectively. , Device failure can be prevented. In addition, the second swing mechanism Sb is attached to both ends of the transmission shaft 20, the swing plate 55 is rotatably attached to the eccentric disk 51, and the second swing mechanism Sb and the sorting table 10 are connected to each other. Since one side is connected so as to be pivotable with one point being supported, the sorting table 10 can be smoothly swung.

また、選別台１０と第２揺動機構Ｓｂとを連結ボルト２９で着脱可能に連結したことからメンテナンスを容易に行うことができ、選別台１０の全体を第２揺動機構Ｓｂに吊下げてあるため、選別台１０を水平方向の往復動と上下動からなる揺動運動をスムースにすることができる。さらに、選別台１０を移動する養殖貝Ｈもスムースに歩進移動をするため、貝が孔に詰まるおそれがなく選別効率を高めることができる。 Further, since the sorting table 10 and the second swing mechanism Sb are detachably connected by the connecting bolt 29, maintenance can be easily performed, and the entire sorting table 10 is suspended from the second swing mechanism Sb. Therefore, the oscillating motion including the horizontal reciprocating motion and the vertical motion of the sorting table 10 can be made smooth. Furthermore, since the cultured shellfish H that moves on the sorting table 10 also moves smoothly and smoothly, there is no possibility that the shellfish are clogged in the hole, and the sorting efficiency can be increased.

前記第２駆動源Ｔｂおよび第２揺動機構Ｓｂを基枠２の上方に位置したことにより、選別作業において選別台１０の養殖貝Ｈに噴射する海水で濡れることが少ないので塩害による錆びや腐食による不具合を防止することができる。 Since the second drive source Tb and the second swing mechanism Sb are positioned above the base frame 2, rust and corrosion due to salt damage are less likely to be wet by seawater sprayed on the cultured shell H of the sorting table 10 in the sorting operation. It is possible to prevent problems caused by

本発明による選別装置１ａ、１ｂによる選別作業工程は、海中から採取した出荷用の養殖貝Ｈをホッパー３１に載置、または入口ホッパー３５にベルトコンベアにより搬送する。次いで、第１，２駆動源Ｔａ、Ｔｂのモータ６を作動させて駆動軸７から伝動手段Ｕまたは直接伝動軸２０を回転させることにより、該伝動軸の両端に設けた第１揺動機構Ｓａまたは第２揺動機構Ｓｂを介して偏心回転させることにより、選別台１０が水平方向の往復動と上下動からなる揺動運動をする。 In the sorting operation process by the sorting apparatuses 1a and 1b according to the present invention, the cultured cultured shell H collected from the sea is placed on the hopper 31 or conveyed to the inlet hopper 35 by a belt conveyor. Next, by operating the motor 6 of the first and second drive sources Ta, Tb to rotate the transmission means U or the direct transmission shaft 20 from the drive shaft 7, the first swing mechanism Sa provided at both ends of the transmission shaft. Alternatively, by rotating eccentrically via the second swing mechanism Sb, the sorting table 10 performs a swing motion including a horizontal reciprocation and a vertical motion.

揺動運動は、第１揺動機構Ｓａと第２揺動機構Ｓｂはほぼ同じであることから、第１揺動機構Ｓａの揺動運動に基づいて説明すると、前記第１揺動機構Ｓａによる選別台１０の揺動運動は、図９イに示すごとく、作動円盤２２の回転により偏心軸２３が最上部位置にくると、篩板１３上の養殖貝Ｈは矢印に示すごとく、最後退位置Ｙの地点から最上部位置Ｗの位置に押し上げられながら出口方向に前進する。 Since the first and second swinging mechanisms Sa and Sb are substantially the same, the swinging motion will be described based on the swinging motion of the first swinging mechanism Sa. As shown in FIG. 9A, when the eccentric shaft 23 comes to the uppermost position by the rotation of the working disk 22, the cultured shell H on the sieve plate 13 moves to the last retracted position as shown by the arrow. It advances in the exit direction while being pushed up from the point Y to the position of the uppermost position W.

次いで、図９ロに示すごとく、偏心軸２３の回転により作動円盤２２の軸心と偏心軸２３とが並行な同一水平位置に移動すると、篩板１３と養殖貝Ｈは共に水平方向に前進しながら最上部位置から降下して最前進位置Ｘに移動する。 Next, as shown in FIG. 9B, when the axis of the working disk 22 and the eccentric shaft 23 are moved to the same horizontal position by the rotation of the eccentric shaft 23, both the sieve plate 13 and the cultured shell H advance in the horizontal direction. However, it descends from the uppermost position and moves to the most advanced position X.

さらに、図９ハに示すごとく、偏心軸２３が回動して最前進位置Ｘから最下部位置Ｚに移動すると、篩板１３は降下しながら図９イの最上部位置Ｗと同じ位置の最下部位置Ｚに後退する。この篩板１３が降下する際、篩板１３が急激に降下するため、篩板上の養殖貝Ｈは一時的に宙に浮いてそのまま最前進位置Ｘに留まる。 Further, as shown in FIG. 9C, when the eccentric shaft 23 rotates and moves from the most advanced position X to the lowest position Z, the sieve plate 13 descends while the uppermost position W in FIG. Retreat to the lower position Z. When the sieve plate 13 descends, the sieve plate 13 descends rapidly, so that the cultured shell H on the sieve plate temporarily floats in the air and remains at the most advanced position X as it is.

さらにはまた、図９ニに示すごとく、偏心軸２３がさらに回転して作動円盤２２の軸心と並行な同一水平位置に移動すると、偏心軸２３は最下部位置Ｚから最後退位置Ｙに回動しながら後退する。さらに最前進位置Ｘに留まった養殖貝Ｈは、篩板１３が後退した位置の最前進位置Ｘで篩板１３とともに上昇して前記最上部位置Ｗに前進移動する（図９イ）。 Furthermore, as shown in FIG. 9D, when the eccentric shaft 23 further rotates and moves to the same horizontal position parallel to the axis of the working disk 22, the eccentric shaft 23 rotates from the lowest position Z to the last retracted position Y. Retreat while moving. Furthermore, the cultured shellfish H staying at the most advanced position X rises together with the sieve plate 13 at the most advanced position X of the position where the sieve plate 13 is retracted and moves forward to the uppermost position W (FIG. 9A).

上記したごとく、作動円盤２２と偏心軸２３の一回転により選別台１０が最後退位置Ｙから最前進位置Ｘに並行移動する往復運動と、最高部位置Ｗと最低部位置Ｚへの上下運動からなる揺動運動を繰返すことにより、養殖貝Ｈが最後退位置Ｙから最上部位置Ｗを経て最前進位置Ｘに移動し、篩板１３だけがまた最後退位置Ｙに移動する動作を繰返すことにより、選別台１０の傾斜と共に養殖貝Ｈが歩進運動をしながら前進移動し、第１、２篩板１３、１５の孔１４、１６から養殖貝Ｈが適宜選別されてそれぞれ落下して排出される。 As described above, from the reciprocating movement in which the sorting table 10 moves in parallel from the last retracted position Y to the most advanced position X by one rotation of the working disk 22 and the eccentric shaft 23, and the vertical movement from the highest position W to the lowest position Z. By repeating the rocking motion, the cultured shell H moves from the last retracted position Y to the most advanced position X via the uppermost position W, and only the sieve plate 13 moves again to the last retracted position Y. The cultured shell H moves forward with the inclination of the sorting table 10 while moving forward, and the cultured shell H is appropriately sorted from the holes 14 and 16 of the first and second sieve plates 13 and 15 and dropped and discharged respectively. The

選別台１０上を移動する大型貝は、第１篩板１３の孔１４から落下せずにそのまま出口側に到達して第１ガイドシューター３７ａから落下し、中型、小型の養殖貝Ｈは、それぞれ第１篩板１３上を移動しながら孔１４でふるい落とされて第２篩板１５に落下し、中型の養殖貝は、そのまま第２篩板１５上を出口まで移動して第２ガイドシューター３７ｂから収容容器４０に収容される。さらに小型の養殖貝Ｈは第２篩板１５の孔１６でさらにふるい落とされて小型貝用の第３ガイドシューター３７ｃから収容容器４０に収容される。 The large shellfish moving on the sorting table 10 does not fall from the hole 14 of the first sieve plate 13 but reaches the exit side as it is and falls from the first guide shooter 37a. While moving on the first sieve plate 13, it is sieved by the holes 14 and falls on the second sieve plate 15, and the medium-sized cultured shellfish moves to the outlet on the second sieve plate 15 as it is and is moved to the second guide shooter 37 b. To be accommodated in the container 40. Further, the small cultured shell H is further screened through the holes 16 of the second sieve plate 15 and stored in the storage container 40 from the third guide shooter 37c for the small shell.

したがって、第１揺動機構Ｓａに懸架された選別台１０は、全体を均等に揺動運動させることができるので、養殖貝Ｈが揺動により跳ねたり踊ったりせず水平状態のまま移動させることができる。また、養殖貝Ｈは、揺動運動により篩板１３、１５の孔１４、１６に嵌ったりすることなくスムースに移動させることができるので効率的に選別作業を行うことができる。 Therefore, since the sorting table 10 suspended by the first swing mechanism Sa can be swung evenly as a whole, the cultured shell H can be moved in a horizontal state without jumping or dancing due to swinging. Can do. Moreover, since the cultured shell H can be moved smoothly without being fitted into the holes 14 and 16 of the sieve plates 13 and 15 by the swinging motion, the sorting operation can be performed efficiently.

万一、貝が孔に嵌った場合でも偏心運動の動作、図９のロからハに移動する水平方向に後退しながら降下する運動により養殖貝が孔から離脱させることができるので、養殖貝が孔に嵌ったままの状態になる現象を少なくすることができる。したがって、選別孔に貝が詰まって小さい貝が選別されずに通過するのを防止することができ、また、篩板上を移動する養殖貝が重なり合って詰まることなくスムースに移動して選別作業を効率よく行うことができる。 Even if the shell fits in the hole, the cultured shell can be detached from the hole by the movement of the eccentric movement, the movement that descends in the horizontal direction moving from B to C in FIG. It is possible to reduce the phenomenon that the state remains fitted in the hole. Therefore, it is possible to prevent the shells from being clogged in the sorting hole and to pass through the small shells without being sorted, and the cultured shells moving on the sieve plate can move smoothly without clogging and clogging. It can be done efficiently.

さらには、選別台１０が水平方向の往復動と上下動をするため、養殖貝Ｈが選別台１０上を揺動しながら移動する際、養殖貝が跳ねたり踊ったりせず水平状態のまま移動させることができるので、移動する養殖貝と養殖貝がぶつかって割れたりひびが入って破損するのを防止することができる。 Further, since the sorting table 10 reciprocates and moves up and down in the horizontal direction, when the cultured shell H moves while swinging on the sorting table 10, the cultured shell does not jump or dance and moves in a horizontal state. Therefore, it is possible to prevent the moving cultured shellfish and the cultured shellfish from colliding with each other to be broken or cracked.
