Description

Seed water selecting device for agricultural rice cultivation Technical Field The invention relates to the technical field of agricultural equipment, in particular to a seed water selecting device for agricultural rice cultivation. Background In the cultivation process of rice, seed screening is a key link for guaranteeing subsequent high yield and high quality. The traditional water separation method in the prior art is widely applied to production practice by virtue of the advantages of simple operation, low cost and effective separation of blighted grains and diseased grains. However, in the actual seed water selection process, the conventional water selection method and the existing equipment have the following defects: Firstly, in the step of preparing brine, a mode of directly adding salt into a water separation container, injecting water and manually stirring is generally adopted. The defects of the method are that the salt is slowly dissolved in water body which is at normal temperature and is static or weakly stirred, and is easily accumulated at the bottom of the water tank to form concentration gradient, so that the concentration of the upper layer and the lower layer of the salt solution is uneven. The nonuniformity directly causes inconsistent seed screening standards, partial full seeds can float by mistake due to local high-concentration saline water, and partial inferior seeds can not float due to local low concentration, so that the screening accuracy and reliability are seriously affected. Second, for the determination of brine density, it has long been dependent on the personal experience of the operator, for example by observing the sinking and floating state of eggs or potato pieces in brine. The method has strong subjectivity and poor repeatability, can not realize standardized and accurate quantitative control, and is difficult to stably prepare the brine meeting the optimal screening density (for example, 1.13 g/cm < 3 >) so that the screening effect has larger fluctuation. In addition, the whole water selection process comprises a plurality of discrete steps of dissolution, blending, screening, collection and the like, the automation degree is low, the manual intervention is frequent, the overall efficiency is low, and the labor intensity is high. At present, although some improved technologies attempt to introduce stirring or heating functions in the prior art, most of the prior art fails to fundamentally solve the core problems of the integration of rapid homogeneous dissolution and accurate density monitoring. For example, direct agitation in a water selection tank can damage seeds, and the heating of the entire large volume of water is energy consuming and inefficient. Therefore, there is a strong need in the art for a specific device that can achieve efficient, accurate, reliable water selection operations. Therefore, the application provides a seed water selecting device for agricultural rice cultivation, which aims to solve the problems.
