Abstract
A mobile seed cleaning and/or separating apparatus has a wheeled, self-propelled chassis mounting a plurality of cleaning and/or separating stations. The stations are interconnected by conveyors which transport the seed through the apparatus. The cleaning and/or separating stations include a coarse screen to remove material of a size larger than the seed to be separated, an aspirator to remove relatively light material, a pair of pocket cylinders to separate materials of different sizes and a screen cylinder to finally screen the seed. After cleaning, the seed passes through a weighing device which continuously batch-weights the seed and actuates a prickling machine to introduce a furyside, mold-inhibitor or other chemical.
Claims14
A mobile seed cleaning apparatus which comprises
- a mobile chassis for mounting a plurality of cleaning or separating stations sequentially interconnected so as to cause seed to be cleaned to pass from a first station to a last station;
- coarse screen means onto which the seed is fed having a predetermined screen size for separating material larger than said screen size by permitting the seed to pass through the screen;
- air separator means having an air duct means and a blower means for removing relatively light material;
- pocket cylinder means comprising two hollow cylinders having internal surfaces formed with a plurality of pockets to receive individual seeds, and being rotatable at predetermined speeds about their respective axes, the axes being inclined downwardly from an inlet end to an outlet end of said cylinder, and having means to vary the axis inclination of each cylinder;
- a collector trough in each of said cylinders extending longitudinally therethrough, each collector trough having a seed auger therein;
- means for moving the trough about a longitudinal axis to vary the position of an upper, open side of the trough relative to the cylinder, the outlet end of each cylinder opening into a first chamber and the outlet of each collector trough opening into a second chamber, each of the first and second chambers having waste outlet passages and seed outlet passages;
- door means for directing material in each chamber to either of the passages;
- screen cylinder means having interchangeable screen cylinders rotatable about a longitudinal axis and internal scraper means to urge the seed through the screen cylinders;
- and
- conveyor means continuously moving the seed from one station to the next.
