FIELD: agricultural engineering, in particular, seed treating equipment. ^ SUBSTANCE: seed treating apparatus has seed hopper with dosing device, tank for toxic chemicals, spraying device, transportation device mounted under hopper, and drive. Transportation device is made in the form of flexible spiral screw. Spraying device is also made in the form of spiral screw mounted within housing inside transportation device at side adjoining uptake part. Drive for transportation device and spraying device has adjustable rotational velocity. Rotational velocity of spraying device is significantly higher than rotational velocity of transportation device. Length of spraying device housing is higher than length of uptake part of transportation device. ^ EFFECT: improved quality of seed treatment, simplified construction and reduced material usage. ^ 1 dwg |
