Multistage screening and drying device for plant seeds

Abstract

The invention discloses a multistage screening and drying device for plant seeds. The multistage screening and drying device for plant seeds comprises a base. Two supporting pillars are installed on the top of the base. A drying device is installed on the tops of the supporting pillars. The drying device comprises a first material baffle and a discharging opening. The bottom of the right end of acommunication pipe communicates with the discharging opening. Ventilation openings are symmetrically formed in the inner left side wall of the drying device in the up-down direction. The top of the drying device is provided with a feeding opening, and a guide pipe is arranged at the bottom end of the feeding opening. A screening device is installed at the right end of the top of the base and comprises a primary screening layer. The primary screening layer, a fine screening layer, a material collecting bin and a fixing block are sequentially arranged on the inner left side wall of the screeningdevice from top to bottom. By means of the multistage screening and drying device for plant seeds, the problem that seed drying is not uniform due to an incomplete drying manner in the prior art canbe solved effectively, and the problems of the complex process of manual seed screening and time consumption in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of production equipment, in particular to a multi-stage screening and drying equipment for plant seeds. Background technique [0002] For agricultural and forestry plants, high-moisture seeds have high respiration intensity, release heat and moisture, and the seeds are prone to mildew, anaerobic respiration and alcohol production, which will poison the seeds. When the moisture content of the seeds is above 40% to 60%, the seeds will die Germination, high seed moisture is conducive to the reproduction of insects and harms the seeds; therefore, after the seeds are harvested, the seeds must be dried in time to reduce their moisture to safe storage moisture to maintain the vigorous vitality and vitality of the seeds. Before the storage, it must be dried so that the water content reaches the standard for safe storage. At the same time, it needs to be screened and stored separately according to the different sizes...

AI Technical Summary

Problems solved by technology

[0005] In view of the above-mentioned shortcomings in the prior art, the present invention provides a multi-stage screening and drying equipment for plant seeds, which can effectively overcome the problem of uneven drying of seeds due to incomplete drying methods in the prior art. As well as the complex process and time-consuming problems of manual seed selection
