ABSTRACT:
Mobile apparatus movable over a crop bearing field such as a field in which onions or garlic are grown. The apparatus includes a pickup device for lifting the food product from the field surface onto a conveyer within the apparatus. Also included are devices which separate the food articles from an admixture of the articles with debris which is inevitably picked up during operation of the apparatus. On the apparatus is a transport conveyer that moves the articles in single file and spaced apart relation under a photoelectric cell. Responsive to the photoelectric cell is an air operated ejection device which ejects debris articles from the transporting conveyer but permits food articles to move to the end of such conveyer.
