The invention belongs to the field of containers used for storing materials, and particularly relates to a treating device for seeds. The treating device includes a preservation
barrel and a rack, thepreservation
barrel is internally provided with a
desiccant cavity and a seed storage cavity and further internally and fixedly provided with a hollow sliding rod, the rack is fixedly provided with amotor, an air cylinder, an
airbag and a
piston cylinder, the motor is connected to the preservation
barrel, and a
cam is coaxially arranged on an output shaft; the air cylinder is communicated with the
airbag through an air inlet
pipe, a
check valve is arranged on the air inlet
pipe, the
airbag is communicated with the
piston cylinder through an air outlet
pipe, and a pressure valve is arranged on the air outlet pipe; the
piston cylinder is internally and slidingly connected with a sliding block and a
magnet, the sliding block and the
magnet are both connected with the inner wall of the
piston cylinder through springs, the hollow sliding rod is communicated with the
piston cylinder, and a
steel ball is arranged in the
desiccant cavity. By adopting the treating device, the purposes of preserving the seeds, improving the
drying effect and providing more convenience for taking and placing are achieved, and the treating device is used for preservation of the
crop seeds.
