As shown in FIGS. 5, 9, and 10, the end portions of the bottom wall body 50, the front side wall body 51, and the rear side wall body 52 are formed so as to be in a horizontal or close posture, and are created at each end portion. The main body support portion of the tank base portion 30b includes a certain weight support portion 53a and inner surface portions of the bottom wall body 50, the front side wall body 51, and the rear side wall body 52, and a stopper portion 53b formed separately from the weight support portion 53a. 53, and the lower part of the tank main body 30a is connected to the tank base 30b by the connecting part 43 and the main body support part 53 of the tank base 30b. That is, as shown in FIGS. 6 and 10, the tank body 30a is placed on the tank base 30b so that the insertion connecting portion 43a of the tank body 30a enters the opening of the tank base 30b. Then, each insertion part connecting part 43a on the four sides enters the inside of the stopper part 53b corresponding thereto, and each mounting connecting part 43b on the four sides is placed on the weight support part 53a corresponding to this, so that the tank body 30a The connecting portion 43 is connected to the main body supporting portion 53 of the tank base portion 30b, and the weight supporting portion 53a of the main body supporting portion 53 receives and acts on the mounting connecting portion 43b of the connecting portion 43 so as to be stored in the tank main body 30a. The weight of the grains is supported, and the stopper portion 53b of the main body support portion 53 is positioned so as to abut against the insertion connection portion 43b of the connection portion 43 so as to suppress the horizontal movement of the tank main body 30a with respect to the tank base portion 30b.

図11に示すようにタンク本体30aの天板部33に取り付けた連結具55と、揚穀装置5の穀粒排出筒5aを有する穀粒排出部5bに備えさせたフック56とにより、タンク本体30aを揚穀装置5に固定するタンク締付け装置57を構成してある。このタンク締め付け装置57は、タンク本体30aの穀粒受入れ部41を揚穀装置5の穀粒排出部5bに、タンク本体30aの連結部43をタンク基部30bの本体支持部53にそれぞれ押し付け操作して揚穀装置5からの穀粒がタンク外にこぼれ出たり、タンク本体30aがタンク基部30bから外れたりすることを防止しながらタンク本体30aを揚穀装置5に締め付け固定するものである。尚、この場合、揚穀装置5の穀粒排出筒5aの先端側がタンク本体30aの穀粒受入れ孔41aからタンク内に入り込んで穀粒供給するように構成してある。そして、機体下方への引き下げ分力により、タンク本体30aの連結部43をタンク基部30bの本体支持部53に押し付け操作する。   As shown in FIG. 11, the tank main body includes a connector 55 attached to the top plate portion 33 of the tank main body 30 a and a hook 56 provided in the grain discharge portion 5 b having the grain discharge cylinder 5 a of the cerealing device 5.

This tank clamping device 57 is operated by pressing the grain receiving part 41 of the tank body 30a against the grain discharge part 5b of the whipping apparatus 5 and the connecting part 43 of the tank body 30a against the body support part 53 of the tank base 30b. Thus, the tank body 30a is fastened and fixed to the cerealing device 5 while preventing the grain from the cerealing device 5 from spilling out of the tank and the tank body 30a from detaching from the tank base 30b. In this case, the tip side of the grain discharge tube 5a of the cerealing device 5 is configured to enter the tank through the grain receiving hole 41a of the tank body 30a and supply the grain. Then, the connecting portion 43 of the tank main body 30a is pressed against the main body support portion 53 of the tank base portion 30b by the downward pulling force.

そして、グレンタンク30の内部を清掃するとか点検するとかの際、タンク締付け装置57を解除側に切り換え操作してタンク本体30aをタンク基部30bから取り外すことにより、タンク本体30aの内部の底側を容易に清掃したり点検したりできるように底側を開放でき、タンク基部30bの内部を容易に清掃したり点検したりできるようにその上方を開放できる。   When the inside of the Glen tank 30 is to be cleaned or inspected, the tank tightening device 57 is switched to the release side to remove the tank body 30a from the tank base 30b, so that the bottom side inside the tank body 30a is removed. The bottom side can be opened so that it can be easily cleaned and inspected, and the upper side can be opened so that the inside of the tank base 30b can be easily cleaned and inspected.

図5に示すようにタンク基部30bの前側壁体51から後側壁体52に亘って貫設された支持ピン62と、図4及び図6に示すようにタンク本体30aの前後側壁部36,36に設けられたガイド体としてのガイド板64とで、図5及び図6に示すグレンタンク支持装置63を構成している。ガイド板64は長孔状のガイド部65と抜け部としての抜け穴66と止め部としてのストッパー67とを有している。 As shown in FIG. 5, support pins 62 penetrating from the front side wall body 51 to the rear side wall body 52 of the tank base 30b, and front and rear side wall parts 36, 36 of the tank body 30a as shown in FIGS. And a guide plate 64 as a guide body provided in FIG. 5 constitutes the Glen tank support device 63 shown in FIGS. 5 and 6. The guide plate 64 has a long hole-shaped guide portion 65, a through hole 66 as a through portion, and a stopper 67 as a stop portion .

このグレンタンク支持装置63の詳細な構成は以下の通りである。   The detailed configuration of the Glen tank support device 63 is as follows.

まず、タンク本体30aの差込み連結部43aがタンク基部30bの開口に入り込むようにしてタンク本体30aをタンク基部30bに載置した状態において、タンク本体30aを本機から脱着する際、タンク本体30aの上端側を機体左右方向に回動可能な高さまで鉛直方向Hに持ち上げた状態(図7及び図8)から、タンク本体30aがタンク基部30bから脱落することを防止しながら長孔状のガイド部65の縁部と支持ピン62との任意の当接位置において、図8に示すように、支持ピンを支点とするタンク本体30a上部の本機左右方向Qへの回動操作を可能にしている。回動の支点である支持ピン62及び長孔状のガイド部65の接点は回動操作中にガイド長68の範囲で長孔状のガイド部65の長手方向における任意の位置に移動可能であるから、タンク本体30aを回動半径方向Pのずれを許容しながら容易に回動させることができる。 First, when the tank body 30a is mounted on the tank base 30b so that the insertion connecting portion 43a of the tank body 30a enters the opening of the tank base 30b, A long hole-shaped guide portion while preventing the tank body 30a from falling off the tank base portion 30b from the state in which the upper end side is lifted in the vertical direction H to a height that allows the upper body side to rotate in the left-right direction (FIGS. 7 and 8). As shown in FIG. 8, at any contact position between the edge of 65 and the support pin 62, the upper part of the tank body 30a with the support pin as a fulcrum can be rotated in the left-right direction Q of the machine. . The contact point of the support pin 62 and the long hole-shaped guide part 65 which is a pivot point of rotation can be moved to an arbitrary position in the longitudinal direction of the long hole-shaped guide part 65 within the guide length 68 during the rotation operation. Thus, the tank body 30a can be easily rotated while allowing a deviation in the rotational radius direction P.

また、支持ピン62と長孔状のガイド部65とを、長孔状のガイド部65の長手方向に沿って相対移動させて、回動半径方向Pの円周側Oにタンク本体30aを移動させる際、支持ピン62が長孔状のガイド部65の長手方向端部に形成されたストッパー67によって制止された状態(図7及び図8)になることで、支持ピン62とガイド板64との係合を維持することができる。 Further, the support pin 62 and the long hole-shaped guide portion 65 are relatively moved along the longitudinal direction of the long hole-shaped guide portion 65 to move the tank body 30a to the circumferential side O in the rotational radius direction P. When the support pin 62 is in a state of being restrained by a stopper 67 formed at the longitudinal end of the elongated hole-shaped guide portion 65 (FIGS. 7 and 8), the support pin 62, the guide plate 64, Can be maintained.

回動操作によってタンク本体30aの前側壁部34の上端が接地した状態(図8)にでき、タンク本体30aをグレンタンク支持装置63により本機に係留したままでタンク基部30b上方の空間確保を可能にしている。   The upper end of the front side wall 34 of the tank body 30a can be grounded (FIG. 8) by the turning operation, and a space above the tank base 30b can be secured while the tank body 30a is moored by the Glen tank support device 63. It is possible.

回動したタンク本体30aの前側壁部34の上端を接地させた状態(図8)で、さらにタンク本体30aを本機から完全に分離させるには、ガイド板64に抜け穴66が構成されているので、タンク本体30aの右側壁部34の上端を接地させたまま、タンク本体30aの底部を持ち上げることで支持ピン62を長孔状のガイド部65に形成した抜け穴66を通してガイド板64との係合を解除することによって、ガイド板64を容易に分離させることができ、タンク本体30aを機体から完全に脱着することができる。 In order for the tank body 30a to be completely separated from the apparatus with the upper end of the front side wall 34 of the rotated tank body 30a grounded (FIG. 8), a through hole 66 is formed in the guide plate 64. Therefore, while the upper end of the right side wall portion 34 of the tank body 30a is grounded, the bottom of the tank body 30a is lifted to engage the support pin 62 with the guide plate 64 through the through hole 66 formed in the long hole-shaped guide portion 65.

An opening can be opened.

次に、タンク本体30aをタンク基部30bに装着する際は、タンク本体30aを底口37が機体側に向く状態で機体右側に側置した後、タンク本体30aの前側壁部34の上端を接地させたままで、図8に示す如くタンク本体30aのガイド板64の抜け穴66をタンク基部30bの支持ピン62に係合させる。ガイド板64の長孔状のガイド部65と支持ピン62とが係合する箇所を支点にしてタンク本体30aの上端側は機体内側に回動するので連結部43を本体支持部53に操作容易に連結することができる。 Next, when the tank body 30a is mounted on the tank base 30b, after placing the tank body 30a on the right side of the body with the bottom 37 facing the body side, the upper end of the front side wall 34 of the tank body 30a is grounded. In this state, the through hole 66 of the guide plate 64 of the tank body 30a is engaged with the support pin 62 of the tank base 30b as shown in FIG. Since the upper end side of the tank body 30a is pivoted to the inner side of the body with the position where the elongated guide portion 65 of the guide plate 64 and the support pin 62 are engaged as a fulcrum, the connecting portion 43 can be easily operated to the body support portion 53. Can be linked to.

このとき、把手39a,取手39bのうちの把手39aを一方の片手で持ち、取手39bを他方の片手で持つことにより、タンク本体30aの上下長さの割りにはタンク本体30aをグレンタンク支持装置63が支点になって上端側が回動するように動かす操作が容易にでき、タンク本体30aのタンク基部30bに対する着脱が行いやすくなる。   At this time, the handle 39a of the handle 39a and the handle 39b is held with one hand, and the handle 39b is held with the other hand, so that the tank body 30a is separated from the vertical length of the tank body 30a by the Glen tank support device. It is possible to easily move the upper end side of the tank body 63a as a fulcrum 63, so that the tank body 30a can be easily attached to and detached from the tank base 30b.
