. Agricultural engineering; a text book for students of secondary schools of agriculture, colleges offering a general course in the subject and the general reader. Agricultural engineering. 300 AGRICULTURAL ENGINEERING picker sheller is the one in more general use and is adapted to smaller machines. The shelling mechanism consists of the picker wheels, the bevel runner, and the rag iron mounted on a spring. These three form a triangular open chute through which the ears of corn are fed. The rag iron is adjustable to adapt the machine to large or small ears. On large machines a self-feeder is provided, which arranges the ears endwise and feeds them into the sheller. In shelling large cribs of corn, extension feeders are provided to convey the corn from the crib to the self-feeder. Cylinder Shellers. The cylinder sheller consists of a beater wheel within a cylinder made up of parallel steel Fig-. 190. A section of a picker-wheel sheller. The corn is fed into one end of the cylinder, and, as the ears pass along, the corn is shelled by being crushed against the cylinder by the revolving beater wheel. Cylinder shellers break up the cobs more than picker shellers. Separating Device. All power shellers should be pro- vided with a shoe and sieve, and a fan to blow out the chaff and dust. Sometimes a vibrating rack or raddle is substi- tuted for the sieve. After being cleaned, the corn is elevated.
