Preparation device of nutrient soil for rice planting

Abstract

The invention discloses a preparation device of nutrient soil for rice planting. The device comprises a screening box, wherein a hopper is communicated with the top of the screening box, a first motoris installed on the top of the screening box, an output shaft of the first motor is inserted into the interior of the screening box and connected with a rotating shaft, a crushing rod is fixed at theside edge of the rotating shaft, a first spiral shaft is connected with the bottom end of the rotating shaft, a funnel and a sieve plate are mounted inside the screening box, the first spiral shaft is located in the funnel, the sieve plate is located below the funnel and arranged obliquely, an exciter is mounted at the bottom of the sieve plate, a sliding groove is formed in the bottom in the screening box, a receiving box is arranged in the screening box, rollers are mounted at the bottom of the receiving box and mounted in the sliding groove in a rolling manner, and a feeding passage is mounted at the side edge of screening box. The device is not easy to block, raw materials are crushed efficiently and circularly, automation of processing is achieved, and the crushing rate is very high.

Description

Technical field [0001] The invention relates to the technical field of rice planting, in particular to a nutrient soil preparation device for rice planting. Background technique [0002] Rice is a kind of herbaceous rice, and it is also the most important and longest food in the rice genus. Originally produced in China, rice was grown in the Yangtze River valley in China 7000 years ago. According to the type of rice, rice can be divided into indica and japonica, early and mid-late rice, glutinous rice and non-glutinous rice. There are other classifications. Rice is generally cultivated in paddy fields, while waterless rice is cultivated. [0003] During the process of planting and cultivation of rice, special nutrient soil is used for cultivation. The nutrient soil needs to be broken during the configuration process. If the broken effect is not good, it will affect the air permeability of the soil, resulting in poor nutrient absorption or rot in the roots of the seedlings The exi...

Problems solved by technology

[0003] In the process of planting and cultivating rice, special nutrient soil will be used for cultivation. The nutrient soil needs to be crushed during the preparation process. If the crushing effect is not good, it will affect the air permeability of the soil, resulting in poor nutrient absorption or root rot of the seedlings. The existing nutrient soil configuration generally uses manual crushing, which is labor-intensive and the crushing efficiency is not high. Therefore, we propose a nutrient soil preparation device for rice planting.
