Tobacco seed water selecting device

Abstract

The invention discloses a tobacco seed water selecting device. The tobacco seed water selecting device comprises a water selecting cavity, a motor, a movable plate and a filtering cavity. The lower end of the water selecting cavity is symmetrically provided with landing legs, and the landing legs play a role in supporting. The upper end of the inner side of the water selecting cavity is in slidingconnection with the movable plate. The middle position of the movable plate is in threaded connection with a threaded rod. The upper end of the threaded rod penetrates the upper end of the water selecting cavity and is fixedly connected with bevel gears which are symmetrically arranged. The tobacco seed water selecting device is novel in design, and when the arranged movable plate downwards moves, unqualified seeds floating on the water layer enter the upper side of the movable plate through through holes; and when the movable plate upwards moves, water containing the unqualified seeds upwards moves under the action of the movable plate and then enters the filtering cavity through a guide pipe, after being filtered by a tapered filter net, the water enters the water selecting cavity againthrough the suction force generated to the lower end of the water selecting cavity by the upward moving of the movable plate, and therefore the water saving effect is achieved.

Description

technical field [0001] The invention relates to a water separation device, in particular to a tobacco seed water separation device. Background technique [0002] Nicotiana belongs to Solanaceae, Solanaceae annual or limited perennial herb with slightly lignified base. Inflorescence terminal, conical, many flowers; capsule ovate or oblong, about equal to persistent calyx, flowering and fruiting in summer and autumn. [0003] As we all know, in the process of planting flue-cured tobacco, tobacco seeds with full particles and heavy quality must be selected for seedling cultivation; due to the small particle size and light weight of tobacco seeds, water selection is usually used for seed selection. It is to put the tobacco seeds into the pot, wash and soak them repeatedly with water, and remove the seeds floating on the water surface; not only is the operation troublesome and labor-intensive, but also the seeds are easy to lose, causing waste, and at the same time causing a lot...
