Seed screening device convenient for replacing screen mesh

Abstract

The invention relates to a screening device, and particularly relates to a seed screening device convenient for replacing a screen mesh. Therefore, the technical problem of the invention is to providethe seed screening device which can improve the seed screening efficiency, reduce the labor intensity, and is convenient to replace the screen mesh. The technical scheme is as follows: the seed screening device convenient for replacing the screen mesh comprises a first base, a first guide rod, a first spring and the like; the first guide rod is provided with two, and are fixed on the left and right sides of the top of the first base respectively, the first guide rod is slidably upwards provided with a guide bushing, the first guide rod is sleeved with the first spring playing a role in buffering, and the bottom end of the first spring is connected with the top of the first base. By means of the invention, a user can conveniently replace and fix the mesh screens with different meshes through the clamping device, the seeds can be screened through the vibration of a vibration motor, and the first spring can prevent the seeds from moving out of a screening frame due to excessive vibrationamplitude of the screening frame, so that a worker does not need to take the screen in the hand to shake left and right to screen the seeds.

Description

technical field [0001] The invention relates to a screening device, in particular to a seed screening device which is convenient for replacing a screen. Background technique [0002] In order to improve the germination rate of seeds, the seeds need to be screened. At present, when the seeds are screened, the seeds are usually manually poured into the screen, and then the workers hold the screen in their hands and shake the seeds from side to side. However, some sundries in the seeds are difficult to screen out, which will reduce the screening efficiency of the seeds, thus requiring replacement of the screen, which will increase the labor intensity of people. Pick up the sundries, which will increase people's workload. Contents of the invention [0003] In order to overcome some sundries in the seeds that are difficult to screen out and will reduce the screening efficiency of the seeds, the screen needs to be replaced, which will increase the labor intensity of people. The...
