Water flow impact type rice seed washing device

Abstract

The invention discloses a water flow impact type rice seed washing device. The water flow impact type rice seed washing device comprises a washing box, a water box and a rotating rod, wherein the washing box is fixed to the top of the water box through a supporting block; a filtering plate is arranged at the middle part of the inner cavity of the washing box; the rotating rod is vertically arranged in the washing box and is of a hollow structure; an outlet cavity, an attracting cavity, a spray nozzle, a tapered cavity and an inlet cavity which communicate are arranged inside the rotating rod from top to bottom in sequence; a small hole of the tapered cavity is connected to the spray nozzle; a position, corresponding to the attracting cavity, of the rotating rod is connected to an attracting pipe; a pump is arranged on the inner wall of the top of the water box; a water pumping end and a water outlet end of the pump are respectively connected to a water pumping pipe and a water outlet pipe; the other end of the water pumping pipe extends to the bottom of the inner cavity of the water box; and the other end of the water outlet pipe is connected to the inlet cavity. The water flow impact type rice seed washing device dispersedly washes seeds in a water flow impact manner, ensures the washing effect, meanwhile can recycle water resources, is more energy-saving and environmentally-friendly.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a water flow impacting rice seed cleaning device. Background technique [0002] Rice is a kind of herbaceous Oryza genus, and it is also the most important and oldest one as food in Oryza genus. Originally produced in China, rice was planted in the Yangtze River Basin of China seven thousand years ago. Rice in the broad sense is different from upland rice; rice in the narrow sense refers to fresh rice, which is different from sea rice. According to the type of rice, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. There are other classifications, rice is generally cultivated in paddy fields, and water rice is cultivated without soil. Rice is generally less than one meter high, and those about 2 meters are newly cultivated giant rice. [0003] In rice seedling raising, the quality of rice seeds is dir...

AI Technical Summary

Problems solved by technology

[0003] In rice seedling raising, the quality of rice seeds is directly related to the later seedlings, and the cleanliness of rice seeds directly affects the quality of rice seeds. At present, most of the seeds are cleaned manually, which is labor-intensive and efficient. Low, and some equipment can replace manual cleaning of rice, but most of these devices use the working method of cleaning a large number of seeds at the same time, which may easily lead to uneven cleaning of seeds
