たって架設した穀粒貯留装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is capable of switching between one side surface of a Glen tank, a laterally outwardly projecting posture, and a retreat posture in which the Glen tank is retired. An auxiliary tank for increasing the storage capacity is pivotally attached at its lower end so as to be able to swing in and out around a support shaft of the auxiliary tank, and the top plate of the auxiliary tank can be bent in the middle of its withdrawal direction. The present invention relates to a grain storage device that is installed over the upper end of the auxiliary tank and the Glen tank.
従来、この種の穀粒貯留装置として、例えば実開平１

の天板に一体に付設したハンドルを揺動操作すること
で、天板を屈伸操作して、補助タンクの張出姿勢と引退
姿勢との切換えを行うようにした構造のものが知られて
いる。Conventionally, as a grain storage device of this type, for example, an actual Kaihei 1
As disclosed in Japanese Laid-Open Patent Publication No. 155738, by swinging the handle integrally attached to the top plate of the auxiliary tank, the top plate is bent and stretched so that the auxiliary tank can be extended and retracted. A structure is known in which switching is performed.
しかしながら、上記従来構造のものにあっては、天板

補助タンクが走行時の振動等によりガタつき易く、か
つ、補助タンクの側壁部分には何ら補強部材が施されて
いなかったために、外力が加ったときに変形し易いもの
であった。However, in the above-described conventional structure, since the lever-shaped handle is provided to bend and extend the top plate, it is necessary to increase the handle length so that the swing operation of the auxiliary tank can be performed lightly. Since the Glen tank and the upper end of the auxiliary tank are connected by the flexible top plate, even if the pivotal support at the base end of the top plate is fixed, the auxiliary tank in the overhanging position may be affected by vibrations during running. It was easy to rattle, and since the side wall portion of the auxiliary tank was not provided with any reinforcing member, it was easily deformed when an external force was applied.
本考案は、上記実情に鑑みてなされたものであって、
補助タンクの出退操作を、その出退操作具の小型化を図
りながらも軽く行うことができるとともに、補助タンク
のガタつきを少くし、かつ、補助タンクの側壁を補強で
きる穀粒貯留装置の提供を目的とする。The present invention has been made in view of the above circumstances,
It is possible to perform the operation of moving the auxiliary tank in and out while lightening the size of the operation tool, reduce the rattling of the auxiliary tank, and reinforce the side wall of the auxiliary tank. For the purpose of provision.
本考案にかかる穀粒貯留装置は、上記目的を達成する
ために、冒記構造のものにおいて、前記支軸と平行な回
動軸周りに回動駆動自在なピニオンギアを、前記グレン

を並設したギア部を備えたラック板を、そのギア部が前
記支軸を中心とする円弧に沿う状態で、前記補助タンク
の側壁における上端縁部にフランジ状に連結してあるこ
とを特徴構成とする。In order to achieve the above-mentioned object, the grain storage device according to the present invention has the above-mentioned structure, in which a pinion gear rotatable about a rotation axis parallel to the support shaft is attached to the upper portion of the grain tank. A rack plate provided with a gear portion in which tooth holes that mesh with the pinion gear are arranged side by side, with the gear portion along an arc centered on the support shaft, the upper edge of the side wall of the auxiliary tank. A characteristic configuration is that the parts are connected in a flange shape.
かかる特徴構成による作用・効果は次の通りである。 The operation and effect of this characteristic configuration are as follows.
すなわち、グレンタンク上側部に設けたピニオンギア

する歯孔を形成しているので、ピニオンギアとの歯合に
おいてもピニオンギアが引っ掛かりやすく、かつピニオ
ンギアの引っ掛かりに対する強度も高いものにできる。That is, since the rack plate meshed with the pinion gear provided on the upper side of the Glen tank is connected to the upper edge of the side wall of the auxiliary tank in a flange shape, the rack plate functions as a reinforcing rib member for the side wall. The upper part of the auxiliary tank is fixed and held by the engagement of the pinion gear and the gear hole of the gear part of the rack plate, the rattling of the auxiliary tank is suppressed, and the pinion gear with a small diameter is driven to rotate. The tank can be moved in and out of the Glen tank around the spindle,
The driving force for the rotation of the pinion gear may be small, and the operation structure for rotationally driving the pinion gear can be configured in a small size. Further, since the rack plate made of a plate material is formed with the tooth holes that mesh with the pinion gear, the pinion gear can be easily caught even in the meshing with the pinion gear, and the strength against the pinion gear being caught can be increased.
従って、本考案によれば、補助タンクを出退駆動する

減化、ひいてはコストの低減化を図ることができるに至
った。Therefore, according to the present invention, since the operation structure for rotationally driving the pinion gear for driving the auxiliary tank in and out can be made small, even if the operation structure is configured as a handle structure, it can be brought into contact with another object. It is possible to configure it in a compact size with little risk of damage, improve safety, reduce rattling of the auxiliary tank, and prevent stress from unnecessarily concentrating on the support shaft etc., improving durability. The rack plate can be reliably operated by the pinion gears, the side wall of the auxiliary tank can be reinforced with the rack plate, and the rack plate is provided in a flange shape from the upper edge of the side wall of the auxiliary tank. In addition to improving the durability, it is possible to reduce the number of parts and thus the cost because there is no need to separately provide a reinforcing member.
