従来の掘り取り装置で掘り上げられた収穫物は、搬送コンベアで斜め上方に移送され、搬送コンベアの後端部から放出され収穫される。しかし、収穫時の圃場の土壌の水分が多いと、掘り取り部で掘り上げられた収穫物に土が付着して落ち難いとともに、収穫物と共に搬送コンベアに載せられた土壌がコンベア部に付着して、コンベア部の隙間から落下し難くなり、収穫物とともに土塊が後方に搬送されて、別工程で土と収穫物を選別する必要があり、効率よい作業が行えない問題があった。従来技術１の掘り取り装置においては、同じ問題が発生する。   The harvested material dug up by the conventional digging apparatus is transferred obliquely upward by the transport conveyor, discharged from the rear end of the transport conveyor, and harvested. However, if there is a lot of soil moisture in the field at the time of harvest, the soil adheres to the harvested material that has been dug up by the digging unit, and it is difficult for the soil to fall, and the soil placed on the conveyor along with the harvested material adheres to the conveyor unit. As a result, it becomes difficult to drop from the gap between the conveyor parts, and the soil mass is transported backward together with the harvested product, so that it is necessary to select the soil and the harvested product in a separate process, and there is a problem that efficient work cannot be performed. In the digging apparatus of the prior art 1, the same problem occurs.

このため本発明の目的は、掘削刃によって掘り上げられたニンニク等の収穫物を、土を篩い落としながら搬送するコンベア部を有した地下茎作物の掘り取り装置において、水分の多い土壌での掘り取り作業でもコンベア部に土壌等が付着しにくく、効率よい作業が行える地下茎作物の掘り取り装置を提供することにある。   For this reason, the object of the present invention is to excavate harvested material such as garlic that has been dug up by the excavating blade, in a rhizome crop digging device having a conveyor unit that conveys the soil while sieving the soil, in soil with much moisture. An object of the present invention is to provide an underground stalk crop digging apparatus that can prevent soil and the like from adhering to a conveyor portion even during work and perform efficient work.

コンベア部３によって搬送されてくる地下茎作物は、前方から後方に斜め上方に向け多数設けた送りローラー（搬送軸）３２の星形のフィンガーロール３０によって跳ね上げられながら後方に移送され、付着した土が篩い落とされ、コンベア部３の後端部から自然落下して貯留部７に収納され収穫される。   The rhizome crops transported by the conveyor unit 3 are transported backward while being spun up by the star-shaped finger rolls 30 of the feed rollers (transport shafts) 32 provided obliquely upward from the front to the rear, and attached soil. Is sieved off, naturally falls from the rear end of the conveyor unit 3, stored in the storage unit 7, and harvested.

圃場の土壌の水分が多い場合には、掘削刃部２で掘り上げた地下茎作物や土壌がコンベア部３に載せられると、土壌がコンベア部３のフィンガーロール３０部に付着して、フィンガーロール３０間の隙間がなくなり、土壌が下方に落下せずに地下茎作物と共に後方に搬送され、バケット７０内に地下茎作物と土壌が混在して収容される。この場合、土壌を取り除く作業が余分に発生して作業効率が著しく悪化する。   In the case where there is a lot of moisture in the soil in the field, when the rhizome crop or soil dug up by the excavating blade 2 is placed on the conveyor 3, the soil adheres to the finger roll 30 of the conveyor 3, and the finger roll 30 There is no gap between them, and the soil is transported backward together with the rhizome crops without falling down, and the rhizome crops and the soil are mixedly accommodated in the bucket 70. In this case, an extra work for removing the soil occurs and the work efficiency is remarkably deteriorated.

本例の発明の掻き落し手段８を、コンベア部３の送りローラー３２の下方部に設けていることによって、各フィンガーロール３０の左右方向の突起３００間に付着する土壌や夾雑物の掻き落しが行われるため、土壌の落下スペースが確保され、土壌が後方に搬送されず、バケット７０内に土壌が入り込むことがなく、水分が多い状態の圃場でも効率よい作業ができる。   By providing the scraping means 8 of the invention of the present example at the lower part of the feed roller 32 of the conveyor unit 3, the soil and foreign matter adhered to the left and right projections 300 of each finger roll 30 can be scraped off. As a result, a space for falling soil is ensured, the soil is not conveyed backward, the soil does not enter the bucket 70, and an efficient operation can be performed even in a field with a lot of moisture.

バケット７０に貯留された地下茎作物が満杯になったら、バケット開放駆動部７２を可動させ、バケット７０上方に設けた進行方向と直行する水平軸の回動支点軸を中心に後方に回動させ、バケット７０前方側から収容された地下茎作物をまとめて排出する。   When the rhizome crops stored in the bucket 70 are full, the bucket opening drive unit 72 is moved and rotated rearward around a rotation fulcrum shaft of a horizontal axis perpendicular to the traveling direction provided above the bucket 70, The rhizome crops accommodated from the front side of the bucket 70 are discharged together.

この発明は、ニンニク等の地下茎作物の掘り取り装置に利用すると効率よい作業が行える。   When the present invention is used in a digging apparatus for rhizome crops such as garlic, an efficient operation can be performed.
