Seed screening device

Abstract

The invention relates to the technical field of agricultural equipment, and discloses a seed screening device which comprises a screening device body. The screening device body comprises a shell, a feeding funnel is fixedly connected to the top surface of the shell, a discharging guide groove is fixedly connected to the right side wall of the shell, and a stirring mechanism is arranged on the inner bottom surface of the shell; and a screening device mechanism comprises a first vertical plate, a gear, a gear belt, a screening plate and a motor, the gear belt is slidably connected with the frontwall face of the first vertical plate, the motor is fixedly connected with the rear wall face of the first vertical plate, an output shaft of the motor penetrates through the first vertical plate, the gear is fixedly connected with an output shaft of the motor, and a dust removal device and an air blowing mechanism are further arranged in the shell. In the moving process of the screening plate, the dust removal device and the air blowing mechanism work alternately, and wizened seeds are removed and then dust is removed while seeds are screened, so that the working efficiency is greatly improved, and the screening process is simpler; and meanwhile, the dust removal device, the air blowing mechanism and the screening device mechanism are all arranged in the shell, so that space is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural equipment, in particular to a seed screening device. Background technique [0002] Seeds are the first in agriculture. The quality of seeds determines the germination rate and harvest in the coming year. After the Zhongjin harvest is completed, the seeds need to be screened to remove small stones and shriveled seeds to ensure the quality of the seeds to ensure next year's seeds A seed screening device is often used when screening seeds, but the existing seed screening device can only separate seeds and stones, and has a single function. When the seeds are mixed with leaves or other lighter impurities, another one is needed. The process makes the screening of seeds cumbersome and complicated, so it is necessary to improve the existing seed screening device.
