以下では、図3から図6を参照して、播種装置1の構造について説明する。播種装置1は、昇降リンク機構20を介して走行機体2の後方に連結され、走行機体2による走行と同時に、種子を所定位置に所定量播くための播種機である。 [Seeding equipment]
Below, with reference to FIGS. 3-6, the structure of the
播種装置1は、種子を貯留するホッパ30から供給される種子を所定量繰り出すための各部材を収容するロールケース31を備える。播種装置1は、6条分の種子を同時に散布できるように、6つのロールケース31を左右方向に並べて備える。ホッパ30は、2条分の種子を収容するように構成されており、下端部が二股に分かれてロールケース31に接続される。つまり、播種装置1は、3つのホッパ30を左右方向に並べて備える。ロールケース31内には、回転可能に構成される繰出ロール32、繰出ロール32の軸方向に形成され、周方向に沿って複数配列される溝33、繰出ロール32の上方に配置される仕切りブラシ34、及び、繰出ロール32の表面に近接して配置され、繰出ロール32の溝33内に保持される種子を繰出ロール32の下部側に案内するガイド部材35が設けられる。
The seeding device 1 includes a roll case 31 that accommodates members for feeding a predetermined amount of seed supplied from a hopper 30 that stores seed. The sowing apparatus 1 includes six roll cases 31 arranged in the left-right direction so that the seeds for six strips can be sprayed simultaneously. The hopper 30 is configured to accommodate two seeds, and the lower end portion is divided into two branches and connected to the roll case 31. That is, the sowing apparatus 1 includes three hoppers 30 arranged in the left-right direction. In the roll case 31, a feeding roll 32 configured to be rotatable, a groove 33 formed in the axial direction of the feeding roll 32, and a plurality of grooves 33 arranged along the circumferential direction, and a partition brush disposed above the feeding roll 32. 34 and a guide member 35 that is disposed in the vicinity of the surface of the feeding roll 32 and guides seeds held in the groove 33 of the feeding roll 32 to the lower side of the feeding roll 32.
ロールケース31の上部であって、繰出ロール32の上方には、籾補給センサ36が設けられている。籾補給センサ36は、種子が少なくなり、籾補給センサ36よりも残量の上面が低くなると警報を出す働きがあるが、籾補給センサ36をロールケース31内に設けることによって、ホッパ30とロールケース31の接続部にブリッジが発生した際に、ロールケース31内の種子量の減少を検知することもできる。これにより、ホッパ30からの接続部で種子詰まりが生じた場合の欠粒を防止することができる。籾補給センサ36による検知結果は、例えば、運転席11のダッシュボード14に表示する、若しくは、警告音を発することでオペレータに伝えることができる。
籾 A replenishment sensor 36 is provided above the roll case 31 and above the feeding roll 32. The cocoon replenishment sensor 36 functions to give an alarm when the seeds are low and the upper surface of the remaining amount is lower than that of the cocoon replenishment sensor 36. However, by providing the cocoon replenishment sensor 36 in the roll case 31, the hopper 30 and the roll It is also possible to detect a decrease in the amount of seed in the roll case 31 when a bridge is generated at the connection portion of the case 31. Thereby, the lack of grains when seed clogging occurs at the connecting portion from the hopper 30 can be prevented. The detection result by the saddle replenishment sensor 36 can be displayed, for example, on the dashboard 14 of the driver's seat 11 or transmitted to the operator by generating a warning sound.
ロールケース31は、樹脂製の軽量ケースである。ロールケース31は、種子を収納するとともに、種子を繰り出すための繰出部として繰出ロール32、仕切りブラシ34、ガイド部材35を内部に収容する。ロールケース31は、ホッパ30と接続される上方が開口するとともに、地面に臨むように下方が開放されている。
The roll case 31 is a lightweight case made of resin. The roll case 31 stores seeds and accommodates a feeding roll 32, a partition brush 34, and a guide member 35 as a feeding part for feeding seeds. The roll case 31 is open at the top connected to the hopper 30 and is opened at the bottom so as to face the ground.
ロールケース31の上部、つまり、上端のホッパ30との接続部から繰出ロール32への供給部にかけては、ホッパ30から供給される種子を一時的に貯留する空間である供給通路40がロールケース31に形成されている。そして、供給通路40の下端であって、繰出ロール32の回転軸心よりも下方には、種子の排出案内部となる排出通路41が形成され、その下端側面に排出口42が設けられる。排出通路41は、排出口42に向けて下方に傾斜するように設けられており、排出口42は、蓋43で塞がれる。以上のように、ホッパ30とロールケース31の供給通路40及び排出通路41とで種子を収納するホッパ部を構成している。
In the upper part of the roll case 31, that is, from the connection part with the hopper 30 at the upper end to the supply part to the feeding roll 32, a supply passage 40 which is a space for temporarily storing seeds supplied from the hopper 30 is a roll case 31. Is formed. A discharge passage 41 serving as a seed discharge guide portion is formed at the lower end of the supply passage 40 and below the rotation axis of the feeding roll 32, and a discharge port 42 is provided on the lower side surface thereof. The discharge passage 41 is provided so as to be inclined downward toward the discharge port 42, and the discharge port 42 is closed with a lid 43. As described above, the hopper 30 and the supply passage 40 and the discharge passage 41 of the roll case 31 constitute a hopper portion that stores seeds.
排出口42に通じる排出通路41は、仕切りブラシ34を挟んで、ガイド部材35が配置される側と反対側に配置されている。つまり、排出通路41は、繰出ロール32の繰出方向と反対側に設けられる。また、供給通路40は、繰出ロール32表面の上部の略半分(より詳しくは、繰出ロール32の外周のうち、回転軸心の水平よりも上方であって、仕切りブラシ34に至るまでの部分)に面するように設けられている。
The discharge passage 41 communicating with the discharge port 42 is disposed on the opposite side to the side on which the guide member 35 is disposed, with the partition brush 34 interposed therebetween. That is, the discharge passage 41 is provided on the side opposite to the feeding direction of the feeding roll 32. Further, the supply passage 40 is substantially half of the upper part of the surface of the feeding roll 32 (more specifically, the portion of the outer periphery of the feeding roll 32 that is above the horizontal axis of the rotation axis and reaches the partition brush 34). It is provided to face.
これにより、排出時に種子がガイド部材35側に漏れてロールケース31の下方に零れ落ちることがなく、確実に回収することができる。従来構造では、ホッパ及びロールケース内の残留物を排出する際に、仕切りブラシやガイド部材を動かしたり、取り外したりする必要があった。そして、残留物を完全に排出する際にはホッパ自体を取り外したり、傾けたりする必要が生じていた。
Thereby, seeds do not leak to the guide member 35 side during discharge and do not fall down below the roll case 31, and can be reliably recovered. In the conventional structure, it is necessary to move or remove the partition brush and the guide member when discharging the residue in the hopper and the roll case. In order to completely discharge the residue, it is necessary to remove or tilt the hopper itself.
供給通路40の水平方向の中心は、繰出ロール32の最外幅よりも外側に位置するように設けられている。言い換えれば、供給通路40の中央部分は、繰出ロール32の外周に接するように設けられる排出通路41の上端よりも下方に配置されている。これにより、ロールケース31の供給通路40内に残留する種子の重心が排出通路41側に位置することとなり、排出通路41を通じて排出する際に、種子の自重を利用した排出が可能となるため、排出速度を向上することができる。
The center in the horizontal direction of the supply passage 40 is provided so as to be located outside the outermost width of the feeding roll 32. In other words, the central portion of the supply passage 40 is disposed below the upper end of the discharge passage 41 provided so as to be in contact with the outer periphery of the feeding roll 32. Thereby, the center of gravity of the seed remaining in the supply passage 40 of the roll case 31 is located on the discharge passage 41 side, and when discharging through the discharge passage 41, the seed can be discharged using its own weight. The discharge speed can be improved.
さらに、排出通路41の下端、つまり、排出口42の下端は、繰出ロール32の回転軸心よりも下方に位置することから、ロールケース31内の種子がスムーズに排出口42に到達するように設定されている。
Furthermore, since the lower end of the discharge passage 41, that is, the lower end of the discharge port 42 is located below the rotational axis of the feeding roll 32, the seeds in the roll case 31 can reach the discharge port 42 smoothly. Is set.
以上のように、供給通路40の下端は、繰出ロール32に臨んで設けられる一方、繰出ロール32の反対側(後方側)では、排出通路41を通じて排出口42に臨んで設けられている。供給通路40から排出通路41への通路は、排出口42側に傾斜して設けられていることから、排出口42から蓋43を外して開放することで、ホッパ30及び供給通路40内に残った種子を簡単に排出することが可能である。言い換えれば、ロールケース31内で貯留された種子の最下端に排出口42が設けられることで、ロールケース31の種子を排出する際に、重力にしたがって排出口42に向かって進み、自然と排出される。これにより、排出速度を向上することができる。
As described above, the lower end of the supply passage 40 is provided facing the feeding roll 32, while the opposite side (rear side) of the feeding roll 32 is provided facing the discharge port 42 through the discharge passage 41. Since the passage from the supply passage 40 to the discharge passage 41 is inclined to the discharge port 42 side, the lid 43 is removed from the discharge port 42 and opened to remain in the hopper 30 and the supply passage 40. It is possible to discharge the seeds easily. In other words, the discharge port 42 is provided at the lowermost end of the seed stored in the roll case 31, so that when the seed of the roll case 31 is discharged, the seed proceeds toward the discharge port 42 according to gravity and is discharged naturally. Is done. Thereby, the discharge speed can be improved.
また、排出口42は、播種装置1の後方側、つまり、機体後端に設けられていることから、オペレータは排出口42にダイレクトにアクセスすることができ、種子を排出する際の作業性を向上することができる。さらに、排出口42を通じてロールケース31内の簡単な掃除を行ったり、繰出ロール32の溝33の詰まりを除去したりでき、排出口42を通じてロールケース31内のメンテナンス性を向上できる。メンテナンス性を向上するという観点では、ロールケース31は、駆動系も一体に1条ずつ取り外すことができ、簡単に単体でのメンテナンスを行うことができる。
Further, since the discharge port 42 is provided at the rear side of the seeding device 1, that is, at the rear end of the machine body, the operator can directly access the discharge port 42, and the workability when discharging seeds is improved. Can be improved. Furthermore, simple cleaning of the inside of the roll case 31 can be performed through the discharge port 42, clogging of the groove 33 of the feeding roll 32 can be removed, and maintainability in the roll case 31 can be improved through the discharge port 42. From the standpoint of improving maintainability, the roll case 31 can also be removed from the drive system one by one, and maintenance can be easily performed as a single unit.
図4に示すように、ロールケース31内では、供給通路40、仕切りブラシ34、及び、ガイド部材35が繰出ロール32の回転方向に対して順に配置されている。そして、ロールケース31内において、仕切りブラシ34及びガイド部材35は、隔壁44を隔てて供給通路40から独立した空間に配置されている。隔壁44は、ロールケース31の供給通路40に臨む内壁から下方に延出される仕切りであり、その下端は、仕切りブラシ34の毛先の根元まで延びて設けられる。ロールケース31から排出通路41を通じて排出する際に、隔壁44によって、種子がガイド部材35側に溢れて零れ落ちることを防ぐことができる。さらに、隔壁44は、繰出ロール32が回転している間は種子をおおよそ摺り切る役割もはたしている。
As shown in FIG. 4, in the roll case 31, the supply passage 40, the partition brush 34, and the guide member 35 are sequentially arranged with respect to the rotation direction of the feeding roll 32. In the roll case 31, the partition brush 34 and the guide member 35 are arranged in a space independent of the supply passage 40 with a partition wall 44 therebetween. The partition wall 44 is a partition that extends downward from the inner wall facing the supply passage 40 of the roll case 31, and the lower end thereof is provided to extend to the root of the hair end of the partition brush 34. When discharging from the roll case 31 through the discharge passage 41, the partition wall 44 can prevent the seed from overflowing to the guide member 35 side and falling down. Further, the partition wall 44 also plays a role of roughly cutting seeds while the feeding roll 32 is rotating.
繰出ロール32は、円柱状の部材であり、その軸方向に沿って設けられた溝33が外周面に複数形成されている。繰出ロール32は、適宜の回転駆動源に接続された回転軸50を有し、その回転軸50を中心として一定方向に回転駆動される。
The feeding roll 32 is a cylindrical member, and a plurality of grooves 33 provided along the axial direction are formed on the outer peripheral surface. The feeding roll 32 has a rotating shaft 50 connected to an appropriate rotation driving source, and is driven to rotate in a fixed direction around the rotating shaft 50.
溝33は、所定の容積を有する空間であり、繰出ロール32の軸方向に沿って形成される。溝33は、繰出ロール32の周方向に沿って等間隔に複数(本実施形態では四つ)設けられる。溝33内に種子を保持した状態で繰出ロール32が回転することで、所定量の種子が連続的に繰り出される。
The groove 33 is a space having a predetermined volume, and is formed along the axial direction of the feeding roll 32. A plurality of grooves (four in this embodiment) are provided at equal intervals along the circumferential direction of the feeding roll 32. A predetermined amount of seeds is continuously fed out by rotating the feeding roll 32 with the seeds held in the grooves 33.
図5に示すように、繰出ロール32は、回転駆動が伝達される回転軸50、回転軸50に固定され、回転軸50とともに回転するロール本体51、ロール本体51と軸方向において対向するように配置される可動部材52、可動部材52にねじ53を介して接続される溝幅調整軸54、及び、溝幅調整軸54を回転させるギア55を備える。
As shown in FIG. 5, the feeding roll 32 is fixed to the rotation shaft 50 to which the rotation drive is transmitted, the rotation shaft 50, and the roll body 51 that rotates together with the rotation shaft 50. The movable member 52 to be arranged, the groove width adjusting shaft 54 connected to the movable member 52 via a screw 53, and a gear 55 for rotating the groove width adjusting shaft 54 are provided.
溝幅調整軸54は、ロール本体51の内部に設けられるバネ56に付勢されたボール57によって、溝幅調整軸54とロール本体51との相対位置(回転方向)が自然に回るのを防止する保持力を与えている。
The groove width adjusting shaft 54 prevents the relative position (rotation direction) between the groove width adjusting shaft 54 and the roll body 51 from turning naturally by a ball 57 biased by a spring 56 provided inside the roll body 51. Giving holding power to.
図6に示すように、ロール本体51の表面には、溝33の一側端部及び底面を構成する溝部51aが形成される。これに対して、ロール本体51を外側から覆うように配置される可動部材52の端部には、溝33の他側端部を構成する溝部52aが形成される。つまり、可動部材52をロール本体51に対して軸方向に移動させることで、溝部51a・52aの位置関係が変更され、溝33の幅が変更される。このようにして溝33の容積を調整可能としている。
As shown in FIG. 6, on the surface of the roll main body 51, a groove 51a that forms one end and a bottom surface of the groove 33 is formed. On the other hand, the groove part 52a which comprises the other side edge part of the groove | channel 33 is formed in the edge part of the movable member 52 arrange | positioned so that the roll main body 51 may be covered from the outer side. That is, by moving the movable member 52 in the axial direction with respect to the roll body 51, the positional relationship between the groove portions 51a and 52a is changed, and the width of the groove 33 is changed. In this way, the volume of the groove 33 can be adjusted.
以上のように構成される繰出ロール32において、ギア55をロール本体51に対して回転駆動することで、溝幅調整軸54を回転させて、ねじ53を介して可動部材52を移動させる。こうして、ロール本体51の溝部51aと可動部材52の溝部52aによって形成される溝33の容積を所望の値に調整することができる。
In the feeding roll 32 configured as described above, the gear 55 is rotationally driven with respect to the roll body 51, thereby rotating the groove width adjusting shaft 54 and moving the movable member 52 via the screw 53. Thus, the volume of the groove 33 formed by the groove 51a of the roll body 51 and the groove 52a of the movable member 52 can be adjusted to a desired value.
仕切りブラシ34は、繰出ロール32の上方(本実施形態では回転軸心の直上方)に配置される。仕切りブラシ34の毛先は、繰出ロール32の表面と所定の隙間を空けるように、繰出ロール32に近接した位置に配置されており、繰出ロール32の溝33から突出した種子の通過を阻止するブラシ状の摺切り部材である。
The partition brush 34 is disposed above the feeding roll 32 (in the present embodiment, directly above the rotation axis). The hair end of the partition brush 34 is disposed at a position close to the feeding roll 32 so as to leave a predetermined gap from the surface of the feeding roll 32, and prevents passage of seeds protruding from the groove 33 of the feeding roll 32. It is a brush-like scraping member.
ガイド部材35は、仕切りブラシ34の下流側に設けられ、仕切りブラシ34を通過した溝33内の種子を外方側から押さえて保持するものである。ガイド部材35は、繰出ロール32の回転軸50の水平方向の高さよりも下側まで延設されている。このように、ガイド部材35は、その表面と繰出ロール32の溝33との間で種子を保持しつつ、仕切りブラシ34を通過した種子を繰出ロール32の下方側に案内する。
The guide member 35 is provided on the downstream side of the partition brush 34, and holds the seed in the groove 33 that has passed through the partition brush 34 from the outside. The guide member 35 extends to a lower side than the horizontal height of the rotation shaft 50 of the feeding roll 32. In this way, the guide member 35 guides the seed that has passed through the partition brush 34 to the lower side of the feeding roll 32 while holding the seed between the surface and the groove 33 of the feeding roll 32.
図7に示すように、繰出ロール32の回転軸50には、従動ギア90が設けられている。回転軸50は、ロールケース31の外側に延出され、その延出部に従動ギア90が固定される。そして、ロールケース31の外側で、従動ギア90と噛み合う駆動ギア91が設けられる。駆動ギア91には、駆動軸92が固定されており、駆動軸92は、各ロールケース31の駆動ギア91に嵌入されている。つまり、駆動軸92は、各繰出ロール32の回転駆動軸として共通のものである。
As shown in FIG. 7, a driven gear 90 is provided on the rotating shaft 50 of the feeding roll 32. The rotating shaft 50 extends to the outside of the roll case 31, and the driven gear 90 is fixed to the extending portion. A drive gear 91 that meshes with the driven gear 90 is provided outside the roll case 31. A drive shaft 92 is fixed to the drive gear 91, and the drive shaft 92 is fitted into the drive gear 91 of each roll case 31. That is, the drive shaft 92 is common as the rotational drive shaft of each feeding roll 32.
駆動ギア91は、エンジン3及びトランスミッション4を介して駆動されるPTO軸93から出力される回転駆動力によって回転駆動される。PTO軸93の後端にはギアケース94が設けられ、ギアケース94から左右方向に連結軸95がそれぞれ延出される。連結軸95の左右一側の中途部に、播種駆動ギア96が固定され、駆動軸92に播種駆動ギア96と噛み合う播種従動ギア97が固定される。播種従動ギア97は、駆動軸92に固定されている。このように、各ロールケース31の回転軸50には、PTO軸93から連結軸95、播種駆動ギア96、播種従動ギア97、駆動軸92、駆動ギア91、従動ギア90を介して回転駆動力が伝達される。
The driving gear 91 is rotationally driven by the rotational driving force output from the PTO shaft 93 driven via the engine 3 and the transmission 4. A gear case 94 is provided at the rear end of the PTO shaft 93, and a connecting shaft 95 extends from the gear case 94 in the left-right direction. A seeding drive gear 96 is fixed to a midway portion on the left and right sides of the connecting shaft 95, and a seeding driven gear 97 that meshes with the seeding drive gear 96 is fixed to the drive shaft 92. The sowing driven gear 97 is fixed to the drive shaft 92. As described above, the rotational driving force is applied to the rotating shaft 50 of each roll case 31 from the PTO shaft 93 through the connecting shaft 95, the sowing drive gear 96, the sowing driven gear 97, the driving shaft 92, the driving gear 91, and the driven gear 90. Is transmitted.
図7及び図8に示すように、溝幅調整軸54を回転させるギア55は、ロールケース31の外側であって、繰出ロール32を回転駆動する従動ギア90及び駆動ギア91と反対側に設けられている。各ギア55と噛み合う操作ギア98が操作軸99に固定されており、操作軸99の一側端部に操作ハンドル100が取り付けられる。操作ハンドル100を回転させることで、操作軸99が回転して操作ギア98及びギア55を回転させて、溝幅調整軸54を回転させる。このようにして、溝幅調整軸54を回転させて、各繰出ロール32の溝33の幅を一様に調整することができる。
As shown in FIGS. 7 and 8, the gear 55 that rotates the groove width adjusting shaft 54 is provided on the outer side of the roll case 31 and on the opposite side of the driven gear 90 and the drive gear 91 that rotationally drive the feeding roll 32. It has been. An operation gear 98 that meshes with each gear 55 is fixed to the operation shaft 99, and an operation handle 100 is attached to one end of the operation shaft 99. By rotating the operation handle 100, the operation shaft 99 is rotated, the operation gear 98 and the gear 55 are rotated, and the groove width adjusting shaft 54 is rotated. In this way, the width of the groove 33 of each feeding roll 32 can be adjusted uniformly by rotating the groove width adjusting shaft 54.
図9に示すように、駆動軸92と駆動ギア91との間における駆動ギア91の駆動伝達経路の上流側にはクラッチ機構101がそれぞれ設けられており、クラッチ機構101を断接することで、各繰出装置の作動を停止することができる。クラッチ機構101は、端から順に隣接する2条分の繰出装置の作動を停止する。つまり、クラッチ機構101によって2条毎に作動の有無を切り替えることが可能である。各クラッチ機構101は、播種装置1を支持するフレームの上部に配置されるクラッチ制御装置102とワイヤ103を介して接続されており、クラッチ制御装置102の作動によって、ワイヤ103のテンションを変えることでクラッチ機構101の断接が制御される。
As shown in FIG. 9, a clutch mechanism 101 is provided on the upstream side of the drive transmission path of the drive gear 91 between the drive shaft 92 and the drive gear 91, and by connecting and disconnecting the clutch mechanism 101, The operation of the feeding device can be stopped. The clutch mechanism 101 stops the operation of the two feeding devices adjacent in order from the end. That is, it is possible to switch the presence or absence of the operation every two lines by the clutch mechanism 101. Each clutch mechanism 101 is connected via a wire 103 to a clutch control device 102 disposed on an upper portion of a frame that supports the seeding device 1, and the tension of the wire 103 is changed by the operation of the clutch control device 102. The connection / disconnection of the clutch mechanism 101 is controlled.
図10に示すように、クラッチ機構101は、ワイヤ103と接続されてワイヤ103のテンションの変化によって左右方向に移動するスライド部材110と、スライド部材110の両端の先端部に設けられるスライダ111と、各スライダ111の移動に伴って移動する爪クラッチ112とを備える。爪クラッチ112は、駆動ギア91の軸部分に設けられる爪部91aと噛み合って係合する。つまり、爪クラッチ112と爪部91aとの係合の有無によってクラッチ機構101による断接が行われる仕組みである。この構造により、各ロールケース31をユニットとして容易に取り外し可能となっている。
As shown in FIG. 10, the clutch mechanism 101 includes a slide member 110 that is connected to the wire 103 and moves in the left-right direction according to a change in the tension of the wire 103, and sliders 111 that are provided at the distal ends of both ends of the slide member 110, A claw clutch 112 that moves as each slider 111 moves is provided. The claw clutch 112 is engaged with and engaged with a claw portion 91 a provided on the shaft portion of the drive gear 91. That is, the clutch mechanism 101 is connected or disconnected depending on whether or not the pawl clutch 112 and the pawl portion 91a are engaged. With this structure, each roll case 31 can be easily removed as a unit.
図11に示すように、クラッチ制御装置102は、各ワイヤ103と接続される屈曲形状のアーム120と、アーム120の屈曲部分を支持するベース部材121と、アーム120の他端と当接し、ベース部材121に支持されるカム122と、カム122と共に回動する大径ギア123と、大径ギア123を回動するモータ124とを備える。カム122のカムプロフィールは、大径部と小径部とを有するものであり、カム122を回転させることで、アーム120のポジションを変更する。モータ124を駆動して大径ギア123を回動させることで、カム122を回動させてアーム120を回動させる。そして、アーム120の回動によってワイヤ103のテンションが変更され、クラッチ機構101が制御される仕組みである。本実施形態では、播種条数のみを切り替える構成であるが、アーム120に設けた取付孔125を利用することで、施肥装置28や薬剤散布装置29などの条数制御を同時に行うことも可能である。
As shown in FIG. 11, the clutch control device 102 is in contact with a bent arm 120 connected to each wire 103, a base member 121 that supports the bent portion of the arm 120, and the other end of the arm 120, A cam 122 supported by the member 121, a large diameter gear 123 that rotates together with the cam 122, and a motor 124 that rotates the large diameter gear 123 are provided. The cam profile of the cam 122 has a large diameter portion and a small diameter portion, and the position of the arm 120 is changed by rotating the cam 122. By driving the motor 124 and rotating the large-diameter gear 123, the cam 122 is rotated and the arm 120 is rotated. Then, the tension of the wire 103 is changed by the rotation of the arm 120, and the clutch mechanism 101 is controlled. In the present embodiment, only the number of sowing lines is switched. However, by using the attachment holes 125 provided in the arm 120, it is possible to simultaneously control the number of lines of the fertilizer application device 28, the chemical spraying device 29, and the like. is there.
次に、図12から図16を参照して、ガイド部材35の構成について説明する。
Next, the configuration of the guide member 35 will be described with reference to FIGS.
ガイド部材35は、ロールケース31への取り付け部が設けられた本体60と、繰出ロール32に形成される溝33と対向する部位に配置される弾性体61と、弾性体61の表面に貼り付けられる表面シート62を備える。
The guide member 35 is affixed to the surface of the elastic body 61, the main body 60 provided with an attachment portion to the roll case 31, the elastic body 61 disposed in a portion facing the groove 33 formed in the feeding roll 32, and The top sheet 62 is provided.
本体60は、中央部分に凹み60aを有し、その凹み60aの内部に弾性体61を収容する。弾性体61は、例えばスポンジ等、搬送物より柔らかい素材からなる部材であり、所定の厚みを有する。弾性体61は、本体60の凹み60aの底面に貼り付けられている。表面シート62は、ガイド部材35の表面の摩擦係数を低減するためのシート部材であり、弾性体61の表面の全面に亘って設けられている。
The main body 60 has a recess 60a in the central portion, and accommodates the elastic body 61 inside the recess 60a. The elastic body 61 is a member made of a material softer than the conveyed product, such as a sponge, and has a predetermined thickness. The elastic body 61 is affixed to the bottom surface of the recess 60 a of the main body 60. The top sheet 62 is a sheet member for reducing the friction coefficient of the surface of the guide member 35, and is provided over the entire surface of the elastic body 61.
このように、弾性体61及び表面シート62は、ロールケース31に固定される本体60に対して貼り付けられている。つまり、弾性体61及び表面シート62は本体60に対して容易に取り替え可能に取り付けられている。
Thus, the elastic body 61 and the top sheet 62 are attached to the main body 60 fixed to the roll case 31. That is, the elastic body 61 and the top sheet 62 are attached to the main body 60 so as to be easily replaceable.
以上のように、ガイド部材35の溝33と対向する部位に弾性体61を配置することで、溝33内に保持された種子が、隣接する種子からの圧力等の外力を受けた場合でも、弾性体61の弾性力で外力を吸収することができる。従って、ガイド部材35による案内時に種子を弾性体61によって保護し、損傷を低減することができる。特に、表面にコーティングが施された種子等の表面の損傷が問題となる搬送物を繰り出す場合に有効である。
As described above, by disposing the elastic body 61 at the portion facing the groove 33 of the guide member 35, even when the seed held in the groove 33 receives an external force such as pressure from an adjacent seed, External force can be absorbed by the elastic force of the elastic body 61. Therefore, the seed can be protected by the elastic body 61 when guided by the guide member 35, and damage can be reduced. In particular, it is effective when feeding a transported object in which damage to the surface such as seeds having a coating on the surface is a problem.
図15は、本体60に、弾性体61と表面シート62が取り付けられた状態の縦方向断面を表した図であるが、ガイド部材35の本体60における両側部60bは、繰出ロール32の表面との隙間が略ゼロとなるように設けられる。他方、本体60における凹み60aが形成される部位、つまり弾性体61と表面シート62が取り付けられた本体60における凹み部位では、繰出ロール32の表面に対して所定の隙間を空けるように設けられる。
FIG. 15 is a view showing a longitudinal section in a state where the elastic body 61 and the top sheet 62 are attached to the main body 60, but both side portions 60 b of the main body 60 of the guide member 35 are connected to the surface of the feeding roll 32. Are provided so that the gap between them is substantially zero. On the other hand, a portion of the main body 60 where the recess 60 a is formed, that is, a recess portion of the main body 60 to which the elastic body 61 and the top sheet 62 are attached, is provided so as to leave a predetermined gap with respect to the surface of the feeding roll 32.
このように、ガイド部材35において、繰出ロール32の溝33と対向する部位では、その表面と繰出ロール32との間に所定の隙間を設け、かつ、それ以外の部位では、その表面と繰出ロール32の表面との間に隙間が生じないように、それぞれの隙間が異ならしめるように構成される。これにより、繰出ロール32の溝33とガイド部材35によって保持される種子は、ガイド部材35と繰出ロール32の隙間を通じて零れ落ちることがなく、所望量の種子を確実に繰り出すことができる。また、部品精度が低く、組み付ける前の状態で、両側部60bの位置が繰出ロール32の外周より内側に位置しても、組み付け後に両側部60bが繰出ロール32に沿うため、ガイド部材35の表面(表面シート62)と繰出ロール32との隙間は確保され、ガイド部材35からの押圧による種子の損傷を防止できる。
As described above, in the guide member 35, a predetermined gap is provided between the surface and the feeding roll 32 at a portion facing the groove 33 of the feeding roll 32, and the surface and the feeding roll are provided at other portions. The gaps are configured to be different from each other so that no gaps are formed between the surfaces of 32. Thereby, the seed held by the groove 33 of the feeding roll 32 and the guide member 35 does not fall down through the gap between the guide member 35 and the feeding roll 32, and a desired amount of seed can be reliably fed out. Moreover, even if the position of both side parts 60b is located inside the outer periphery of the feeding roll 32 in a state before assembling, the parts 60b follow the feeding roll 32 after assembling. A gap between the (surface sheet 62) and the feeding roll 32 is ensured, and seed damage due to pressing from the guide member 35 can be prevented.
図16に示すように、ガイド部材35の表面(表面シート62の表面)と繰出ロール32の表面との隙間は、ガイド部材35への入口側の隙間D1に比べて、出口側の隙間D2が小さくなるように設定されるとともに、入口側から出口側にかけて徐々に小さくなるように設定されている。
As shown in FIG. 16, the gap between the surface of the guide member 35 (the surface of the top sheet 62) and the surface of the feeding roll 32 is smaller than the gap D <b> 1 on the inlet side to the guide member 35. In addition to being set to be smaller, it is set to be gradually smaller from the inlet side to the outlet side.
このように、ガイド部材35の上端の入口側の隙間D1を下端の出口側の隙間D2よりも大きく取ることで、溝33からはみ出した種子がガイド部材35と接触する際に損傷する可能性を低くすることができ、ガイド部材35の出口側の隙間D2を狭くすることで、種子がガイド部材35と繰出ロール32の隙間から零れ落ちることを防ぐことができる。
Thus, by taking the gap D1 on the inlet side at the upper end of the guide member 35 larger than the gap D2 on the outlet side at the lower end, the seed protruding from the groove 33 may be damaged when coming into contact with the guide member 35. By reducing the gap D2 on the outlet side of the guide member 35, seeds can be prevented from falling from the gap between the guide member 35 and the feeding roll 32.
また、出口側の隙間D2は、搬送物である種子の最小幅W1の半分以下に設定されている。これにより、種子がガイド部材35と繰出ロール32の隙間から零れ落ちることを確実に防ぐことができる。なお、搬送物を籾とした場合には、ガイド部材35と繰出ロール32との隙間の下端(隙間D2)を2.0mm以下とすることが好ましい。
Further, the clearance D2 on the outlet side is set to be equal to or less than half of the minimum width W1 of the seed that is the conveyed product. Thereby, it can prevent reliably that a seed spills from the clearance gap between the guide member 35 and the delivery roll 32. FIG. In addition, when a conveyed product is a ridge, it is preferable that the lower end (gap D2) of the clearance gap between the guide member 35 and the delivery roll 32 is 2.0 mm or less.
なお、本実施形態では、繰出装置1によって繰り出される搬送物を楕円球形の種子としているため、最小幅W1を楕円球の小径W1としている。例えば、球形の搬送物の場合は、最小幅W1は直径となる。
In the present embodiment, since the conveyed product fed by the feeding device 1 is an elliptical spherical seed, the minimum width W1 is the small diameter W1 of the elliptical sphere. For example, in the case of a spherical transported object, the minimum width W1 is a diameter.
ガイド部材35の繰出ロール32の表面との隙間の設定は、例えば、本体60の凹み60aの厚みを徐々に変えるとともに、弾性体61の厚みを均一にしておくことで実現可能である。このように弾性体61の厚みを均一にすることで、弾性体61を本体60に配置する際の手間が少なくなるという利点がある。
The setting of the gap between the guide member 35 and the surface of the feeding roll 32 can be realized, for example, by gradually changing the thickness of the recess 60a of the main body 60 and making the thickness of the elastic body 61 uniform. By making the thickness of the elastic body 61 uniform in this way, there is an advantage that the labor for arranging the elastic body 61 in the main body 60 is reduced.
なお、これらの例にとらわれず、弾性体61の厚みを部分的に変えて弾性力をロール周方向に沿って微調整したり、弾性体61の一部又は全部を繰出ロール32に故意に接触させてクリアランスを調整したりすることなども考えられる。
Without being limited to these examples, the thickness of the elastic body 61 is partially changed to finely adjust the elastic force along the roll circumferential direction, or part or all of the elastic body 61 is intentionally brought into contact with the feeding roll 32. It is also possible to adjust the clearance.
本実施形態では、溝33とガイド部材35との間で保持された種子を保護するために、ガイド部材35の表面側に弾性体61を配置したが、図17に示すように、溝33の底面に配置しても良いし、ガイド部材35と溝33の両方に弾性体61を配置しても良い。溝33の底面に配置する場合も、ガイド部材35の凹み60aに配置する際と同様に貼り付ける等することで配置可能である。溝33の底面に弾性体61を配置することで、搬送物が溝33の底面側にめり込むことによって、搬送物の表面に損傷が生じることを防止できる。
In the present embodiment, in order to protect the seed held between the groove 33 and the guide member 35, the elastic body 61 is arranged on the surface side of the guide member 35. However, as shown in FIG. The elastic body 61 may be disposed on both the guide member 35 and the groove 33. Also when arrange | positioning in the bottom face of the groove | channel 33, it can arrange | position by sticking etc. similarly to the time of arrange | positioning at the dent 60a of the guide member 35. By disposing the elastic body 61 on the bottom surface of the groove 33, it is possible to prevent damage to the surface of the conveyed product due to the conveyed product sinking into the bottom surface side of the groove 33.
以下では、図18から図20を参照して、仕切りブラシ34の作用幅を溝33の幅に応じて調整する各実施形態について説明する。つまり、以下の実施形態は、仕切りブラシ34のブラシ部の長さを繰出ロール32の軸方向に調整可能としたものである。
Hereinafter, with reference to FIGS. 18 to 20, each embodiment in which the working width of the partition brush 34 is adjusted according to the width of the groove 33 will be described. That is, in the following embodiment, the length of the brush portion of the partition brush 34 can be adjusted in the axial direction of the feeding roll 32.
図18は、仕切りブラシ34を幅方向に複数に分割して、仕切りブラシ34よりも幅の小さい分割ブラシ70を複数配列し、かつ、溝33の幅を超えた部位では、分割された仕切りブラシ34に代えてその空間を埋めるブロック71を設置する実施形態を示す。ブロック71は、繰出ロール32の軸方向又は周方向に種子が流出することを防止する流出防止部であり、分割ブラシ70のブラシ部に隣接して配置されている。
In FIG. 18, the partition brush 34 is divided into a plurality of parts in the width direction, and a plurality of divided brushes 70 having a width smaller than that of the partition brush 34 are arranged. An embodiment in which a block 71 that fills the space instead of 34 is installed is shown. The block 71 is an outflow prevention unit that prevents seed from flowing out in the axial direction or the circumferential direction of the feeding roll 32, and is disposed adjacent to the brush unit of the divided brush 70.
ブロック71は、仕切りブラシ34の奥行き(繰出ロール32の回転方向に沿った長さ)と同じ奥行きを有する略直方体形状の部材であり、繰出ロール32側の表面と繰出ロール32の表面との間の隙間ができる限り小さいものを用いることで、ブロック71側への種子のこぼれを防ぐことができる。
The block 71 is a substantially rectangular parallelepiped member having the same depth as the depth of the partition brush 34 (the length along the rotation direction of the feeding roll 32), and between the surface of the feeding roll 32 and the surface of the feeding roll 32. By using the one having the smallest possible gap, seed spillage to the block 71 side can be prevented.
また、ブロック71の繰出ロール32の回転方向上流側の側面を分割ブラシ70に向かうようにテーパ状に延出することで、溝33が存在しない部位であるブロック71の側面に滞留する種子を分割ブラシ70側に案内して、滞留量を低減することも可能である。
Further, the side surface on the upstream side in the rotation direction of the feeding roll 32 of the block 71 is extended in a tapered shape so as to face the dividing brush 70, thereby dividing the seed staying on the side surface of the block 71 where the groove 33 does not exist. It is also possible to reduce the staying amount by guiding to the brush 70 side.
図19は、仕切りブラシ34の入口側及び出口側の側面、並びに溝33側の側面を覆うカバー72を設置する実施形態を示す。カバー72は、仕切りブラシ34のブラシ部と一体的に設けられる流出防止部である。
FIG. 19 shows an embodiment in which a cover 72 is installed to cover the side surfaces on the inlet side and outlet side of the partition brush 34 and the side surface on the groove 33 side. The cover 72 is an outflow prevention part provided integrally with the brush part of the partition brush 34.
カバー72は、平板を同一方向に二度山折りすることで形成される屈曲部材であり、その両端に切り込み73が設けられている。仕切りブラシ34の基部34aの両側面には、切り込み73に応じたピン34bを設け、カバー72の切り込み73をピン34bに取り付ける。このように、カバー72を仕切りブラシ34に対して着脱自在に取り付ける。
The cover 72 is a bending member formed by folding a flat plate twice in the same direction, and cuts 73 are provided at both ends thereof. Pins 34b corresponding to the cuts 73 are provided on both side surfaces of the base 34a of the partition brush 34, and the cuts 73 of the cover 72 are attached to the pins 34b. Thus, the cover 72 is detachably attached to the partition brush 34.
以上のように、仕切りブラシ34にカバー72を取り付ける簡単な構成で、仕切りブラシ34の作用幅を調整できる。
As described above, the operating width of the partition brush 34 can be adjusted with a simple configuration in which the cover 72 is attached to the partition brush 34.
図20は、ブラシ部34の他に、ブラシが形成される幅の異なる他の仕切りブラシ75・76・77を用意し、溝33の幅に応じた幅を有するブラシ部材を選択する実施形態を示す。この場合も、繰出ロール32の回転方向上流側の側面をテーパ状に延出することで、仕切りブラシ75・76・77の手前に滞留する種子を低減することが可能である。つまり、各仕切りブラシ75・76・77のブラシ部が形成された部位に隣接する部位を流出防止部として一体的に形成することも可能である。
FIG. 20 shows an embodiment in which, in addition to the brush portion 34, other partition brushes 75, 76, and 77 having different widths on which the brush is formed are prepared, and a brush member having a width corresponding to the width of the groove 33 is selected. Show. Also in this case, it is possible to reduce seeds staying in front of the partition brushes 75, 76, and 77 by extending the side surface on the upstream side in the rotation direction of the feeding roll 32 in a tapered shape. That is, it is also possible to integrally form the part adjacent to the part where the brush part of each partition brush 75, 76, 77 is formed as the outflow prevention part.
以上のように、複数のブラシ部材から最適な作用幅のものを選択することが可能である。特に、溝33の幅(所望の繰出量)が予め決定されている場合に有効である。
As described above, it is possible to select one having an optimum working width from a plurality of brush members. This is particularly effective when the width (desired feed amount) of the groove 33 is determined in advance.
以上、図18から図20に示す実施形態によれば、仕切りブラシ34の作用幅を溝33の幅に応じて調整することができる。従って、溝33から幅方向の側方に種子がはみ出すことがなく、溝33の幅外から種子が通過する割合が減り、所定位置への所定量の点播が担保される。また、想定外の箇所を通る種子が減ることで、種子の損傷を低減することも可能である。
As mentioned above, according to embodiment shown in FIGS. 18-20, the action | operation width | variety of the partition brush 34 can be adjusted according to the width | variety of the groove | channel 33. FIG. Therefore, seeds do not protrude laterally in the width direction from the groove 33, the ratio of seeds passing from outside the width of the groove 33 is reduced, and a predetermined amount of seeding at a predetermined position is ensured. Moreover, it is also possible to reduce seed damage by reducing the number of seeds that pass through unexpected locations.
図21及び図22は、仕切りブラシ34の繰出ロール32の回転方向上流側及び下流側のそれぞれの側面に流出防止壁78を設けた実施形態を示す。流出防止壁78は、繰出ロール32の周方向に沿って設けられる平板部材であり、その下端は繰出ロール32の外周面に沿うように形成されている。流出防止壁78は、仕切りブラシ34のブラシ形成部に隣接した箇所(繰出ロール32の軸方向外側)に配置されており、仕切りブラシ34のブラシ部分から種子が繰出ロール32の軸方向に流出することを防止する。流出防止壁78の形状としては上記の形状に限定されず、軸方向の搬送物の流出を防ぐものであれば良い。
21 and 22 show an embodiment in which an outflow prevention wall 78 is provided on each side of the upstream side and the downstream side in the rotational direction of the feeding roll 32 of the partition brush 34. The outflow prevention wall 78 is a flat plate member provided along the circumferential direction of the feeding roll 32, and its lower end is formed along the outer peripheral surface of the feeding roll 32. The outflow prevention wall 78 is disposed at a location adjacent to the brush forming portion of the partition brush 34 (outside in the axial direction of the feeding roll 32), and seeds flow out from the brush portion of the partition brush 34 in the axial direction of the feeding roll 32. To prevent that. The shape of the outflow prevention wall 78 is not limited to the above shape, and any shape can be used as long as it prevents the outflow of the conveyed product in the axial direction.
図23に示すように、仕切りブラシ34は、その毛先が繰出ロール32の回転方向上流側に向けて傾いた姿勢で配置することも可能である。例えば、仕切りブラシ34を繰出ロール32の回転軸50から5°程度向けて傾いた状態で配置し、仕切りブラシ34全体としては繰出ロール32の回転軸50から見て回転方向下流側に傾けて配置する。つまり、仕切りブラシ34の毛先の先端が根元よりも繰出ロール32の回転方向上流側に位置するように設置する。
As shown in FIG. 23, the partition brush 34 can be arranged in a posture in which the hair tip is inclined toward the upstream side in the rotation direction of the feeding roll 32. For example, the partition brush 34 is disposed in a state inclined about 5 ° from the rotation shaft 50 of the feeding roll 32, and the partition brush 34 as a whole is disposed to be inclined downstream in the rotation direction as viewed from the rotation shaft 50 of the feeding roll 32. To do. That is, it installs so that the front-end | tip of the hair | bristle tip of the partition brush 34 may be located in the rotation direction upstream of the delivery roll 32 rather than the root.
このような構成により、仕切りブラシ34の毛先は、種子からの圧力を受けることで略鉛直方向にたわみ、溝33からはみ出した種子をブロックし易くなる。言い換えれば、仕切りブラシ34の毛先で繰り出される種子を面で迎えるように、種子と仕切りブラシ34がコンタクトすることで、溝33の上方に出た種子を確実に仕切ることができる。
With such a configuration, the hair end of the partition brush 34 bends in a substantially vertical direction by receiving pressure from the seed, and the seed protruding from the groove 33 is easily blocked. In other words, the seeds coming out above the grooves 33 can be reliably partitioned by contacting the seeds and the partition brush 34 so that the seeds fed out by the bristles of the partition brush 34 come in contact with the surface.
また、図23に示すように、仕切りブラシ34を繰出ロール32の上下方向の頂点よりも回転方向上流側に位置させる。このように、仕切りブラシ34を繰出ロール32の直上方よりも下方に配置することで、仕切りブラシ34を通過する際に、溝33から溢れた種子に対して、その上方に滞留する種子から下方への圧力が掛かる。このように、溝33外の種子が仕切りブラシ34を通過する際のブレーキとして自然と作用することで、溝33から突出した種子が仕切りブラシ34へ侵入する確率を小さくすることができる。
Further, as shown in FIG. 23, the partition brush 34 is positioned on the upstream side in the rotational direction from the top of the feeding roll 32 in the vertical direction. As described above, by arranging the partition brush 34 below the upper side of the feeding roll 32, when passing through the partition brush 34, the seed overflowing from the groove 33 is lowered from the seed staying above the seed. Pressure is applied. In this manner, the seeds outside the groove 33 naturally act as a brake when passing through the partition brush 34, so that the probability that the seed protruding from the groove 33 enters the partition brush 34 can be reduced.
