Description

【０００１】
【産業上の利用分野】
本発明は、例えばキャベツ、レタス、ハクサイ等を収穫する結球野菜収穫機に関する。
【０００２】
【従来の技術】
従来、キャベツ、レタス、ハクサイ等の結球野菜は、作業者が葉球の堅さを判断し乍ら人力収穫していた。
【０００３】
【発明が解決しようとする課題】
従来の収穫作業は、運搬台車の使用によって葉球搬出が機械化されていたが、茎を切断して葉球を台車に積む作業が人力依存されていたから、労力の軽減並びに作業能率の向上などを容易に行い得ない等の問題があった。そこで、左右一対のスクリューコンベアを野菜の葉球下側に入り込ませ、葉球を持上げる技術が開発されたが、スクリューコンベアによって野菜の茎を挾む状態となり、葉球が不安定に支持され、また根土がスクリューコンベアを介して葉球に付着し易く、商品価値を低下させたり、出荷時の洗浄作業など後処理が面倒になる等の問題があった。
【０００４】
【課題を解決するための手段】
然るに、本発明は、圃場面の野菜の葉球部を左右両側から挾んで地上に持上げる結球野菜収穫機において、野菜の葉球下側の茎を挾んで上方に引抜く左右堀取ディスクを前低後高に斜設させ、前記ディスクを強制回転させてディスク上面側に野菜の葉球を載せると共に、野菜の葉球部を両側から挾持する左右一対の前後搬送体と、前記野菜の葉球を下方側から支える左右ガイド体を設け、前記ディスク上面の野菜を前搬送体によって両側から弾圧挾持して後方に移送し、送り終端部で野菜の根部をカッターによって切除させた後、野菜を後搬送体に受継いで両側から弾圧挾持して後方に移送し、後搬送体送り終端部で上面コンベアにより高さを制限した野菜の茎をカッターによって切断させるもので、極めて安定した姿勢で野菜の葉球を支持し得ると共に、根土が茎を介して空中に吊下されるから、根土が葉球に付着する不具合をなくし得、商品価値低下の防止並びに出荷処理の簡略化などを容易に図り得るものである。

[Industrial applications]
The present invention relates to a head vegetable harvester for harvesting cabbage, lettuce, Chinese cabbage, and the like.
[0002]
[Prior art]
Conventionally, head vegetables such as cabbage, lettuce, and Chinese cabbage have been manually harvested by an operator while judging the hardness of the leaf ball.
[0003]
[Problems to be solved by the invention]
In the conventional harvesting work, the transport of lobes was mechanized by using a transport trolley, but the work of cutting the stems and loading the lobes on the trolley was dependent on human labor, so it was easy to reduce labor and improve work efficiency. There was a problem that it could not be performed. Therefore, a technique has been developed in which a pair of left and right screw conveyors are inserted under the leaf of the vegetable to lift the leaf, but the screw conveyor sandwiches the stems of the vegetable and the leaf is unstablely supported. In addition, there is a problem that root soil easily adheres to the leaf ball via the screw conveyor, lowering the commercial value and complicating post-processing such as washing work at the time of shipping.
[0004]
[Means for Solving the Problems]
However, the present invention relates to a headed vegetable harvesting machine that lifts a leaf ball portion of a vegetable in a field scene from both left and right sides and lifts the ground to the ground. A pair of left and right transporters for holding the vegetable leaf ball on both sides while rotating the disk obliquely at the front low and high heights and placing the vegetable leaf ball on the upper surface of the disk, and the vegetable leaf A left and right guide body for supporting the ball from below is provided , the vegetables on the upper surface of the disk are elastically clamped from both sides by the front carrier and transported rearward, and after the root of the vegetables is cut off by the cutter at the feed end, the vegetables are removed. Inherited by the rear carrier, clamped from both sides and conveyed to the rear, and cut the stems of vegetables whose height was restricted by the upper conveyor at the rear end of the rear carrier using a cutter, and vegetables in an extremely stable posture Support leaf ball In addition, since the root soil is suspended in the air via the stems, it is possible to eliminate the problem that the root soil adheres to the leaf bulb, and to easily prevent a decrease in commercial value and simplify the shipping process. is there.
