Seed screening device

Abstract

The invention discloses a seed screening device. The seed screening device comprises a top plate, a base, a transmission, a stirring unit and a vibration barrel; the transmission is connected to the stirring unit through a rotating shaft; the stirring unit is positioned on the upper side in the vibration barrel; an inclined screening module is fixedly arranged on the lower side in the vibration barrel; a vibration motor is fixedly arranged under the vibration barrel; at least four springs are arranged between the vibration barrel and the base; and a seed outlet is formed in one side of the vibration barrel. The seed screening device is simple in structure; seeds to be screened are poured in the vibration barrel; and under coaction of the stirring unit, the vibration motor and the springs,excellent seeds slide to a first outlet along a first screening plate, qualified seeds slide to a second outlet along a second screening plate, and unqualified seeds slide to a third outlet along theinner bottom surface of the vibration barrel, so that the screening can be quickly finished by using simple structure, and the seed screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of screening, in particular to a seed screening device. Background technique [0002] Before the seeds are planted, they need to be screened in order to ensure the germination rate of the seeds. However, at present, most of the seed screening is basically manual selection and screening using sieves, which is time-consuming and labor-intensive, and the separation efficiency is low. Moreover, the existing screening device has a complicated structure and troublesome operation, and the good seeds after screening are easily mixed with unqualified seeds Seeds, the seeds after screening are only divided into two kinds of qualified and unqualified, can not get the classification of excellent seeds, qualified seeds and unqualified seeds, and the efficiency of screening seeds is not high. Contents of the invention [0003] The purpose of the present invention is to provide a seed screening device with simple struct...
