A rice seed water separation device that uses buoyancy to catch defective products

Abstract

The invention discloses a rice seed water concentration device using buoyancy to catch defective seeds. The rice seed water concentration device comprises a box body, a water filling pipe and a waterdraining pipe, wherein the water filling pipe is fixed to the middle position of the inner chamber of the box body through a pipe support, and a catching box which can move up and down is arranged inthe inner chamber of the box body. The catching box is designed with a bottom opening, and an air bag is arranged at the top of the catching box. Filter plates are symmetrically arranged on the left side and the right side of the lower part of the catching box. The middle part of each filter plate is rotationally connected on the inner wall of the box body through an elastic hinge, and the filterplates are in an inclined state under a normal condition. Limiting plates are symmetrically and fixedly arranged on the left side and the right side of the middle pipe body of the water filling pipe.Touch rods matched with the filter plates are fixedly arranged at the bottom of the catching box. The rice seed water concentration device has the advantages of simple structure and reasonable design.By the arrangement of the catching box and a sealing plate, the rice seed water concentration device can effectively complete the catch of defective seeds. Moreover, the integral structure is drivencompletely by buoyancy in the process of operation, and an additional power source is not needed, so that the rice seed water concentration device accords with the development theme of environmental protection at present.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a rice seed water separation device which utilizes buoyancy to catch defective products. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest kind of grain in Oryza genus. It is also called Asian cultivated rice, and it can be said to be rice in simple terms. It is an annual, gramineous plant, monocotyledonous, sexually warm and humid, about 1 meter high when mature, with slender leaves, about 50 to 100 cm long and 2 to 2.5 cm wide. The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 mm down from the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Typical rice grains are 5 to 12 mm long and 2 to 3 mm thick.

AI Technical Summary

Problems solved by technology

[0003] Due to the uneven quality of the seeds, it is necessary to remove the defective products, that is, dry seeds, before planting, which is usually achieved by water separation. The most primitive water separation device has a relatively simple structure, and it is necessary to manually clean the seeds floating on the liquid surface. Removing shriveled seeds is cumbersome to operate. Nowadays, there are also some equipment that can replace manual removal of shriveled seeds. For example, the patent application number 201721289373.0 discloses a seed water separation device for animal husbandry planting. It can complete the collection of shriveled seeds with devices such as water separation boards, but its overall structure is too complicated, and a power source needs to be installed, which does not meet the current development theme of green environmental protection
