上記した従来の球状作物調製機では、調製処理するために球状作物を調製装置へ搬送装置で搬送し、その搬送過程で球状作物を一定条件に整えた後、球状部を排出シュータの受入部内に送り込み、その受入部内に設けている排出切換板の傾倒により機外に排出するように構成にしている。
その時、排出シュータ内に第２切断装置Ｆで切り離されたヒゲ根、玉葱に付着した土砂等が調製処理された玉葱と一緒に排出され、それらが排出シュータを流落する際ヒゲ根、土砂等が堆積ぎみとなり、連続作業を続けているとその堆積が玉葱を停滞させることとなり、その結果排出シュータ内で詰まりが発生し、連続作業が不可能となる。 In the conventional spherical crop preparation machine described above, the spherical crop is transported to the preparation device by a transport device for the preparation process, and after adjusting the spherical crop to a certain condition during the transport process, the spherical portion is placed in the receiving portion of the discharge shooter. It is configured so that it is discharged out of the machine by tilting of the discharge switching plate provided in the receiving portion.
At that time, whisker roots, soil and sand adhering to the onion separated by the second cutting device F are discharged into the discharge chute together with the prepared onion, and when they flow down the discharge chute, whisker roots, earth and sand, etc. If the continuous operation is continued, the accumulation causes the onion to stagnate. As a result, clogging occurs in the discharge shooter, and continuous operation becomes impossible.
