Mobile four-in-one seed selection unit

Abstract

The invention relates to a moving four-in-one seed fine selecting machine unit and belongs to feed fine selecting machinery. First and second lifting conveyors and a draft fan are assembled and arranged on a walking type machine frame assembly, the first lifting conveyor is communicated with an air separation mechanism, a vibration screening mechanism is communicated with a double-cone-tube upper row large-hole sorting mechanism, the double-cone-tube upper row large-hole sorting mechanism is communicated with a double-cone-tube lower row small-hole sorting mechanism, the second lifting conveyor is respectively communicated with the double-cone-tube lower row small-hole sorting mechanism and a negative pressure specific gravity sorting mechanism, the draft fan is communicated with the negative pressure specific gravity sorting mechanism, a sieve type back selecting vibration flow groove is arranged on the walking type machine frame assembly and is communicated with the negative pressure specific gravity sorting mechanism and the second lifting conveyor, a material blocking ring is fixedly arranged on the inner wall of a rolling tube casing of the double-cone-tube upper row large-hole sorting mechanism, and the hole shape of a hole rolling tube is horseshoe hole shape. The moving four-in-one seed fine selecting machine unit has the advantages that the fine selecting effect is good, the efficiency is high, the universality is high, the structure is reasonable, the total body is compact, the operation is reliable, the operation transfer service is convenient, and the operation cost is low.

Description

technical field [0001] The invention belongs to a seed selection machine, and mainly relates to a four-in-one seed selection unit of movable air selection, vibration screening, pocket selection and specific gravity selection. Background technique [0002] At present, the cleaning methods of crop seeds mainly include four methods: winnowing, vibration screening, roller socket selection and specific gravity selection. grains and dust; vibrating screening is to complete the cleaning according to the width and thickness of the material, mainly to remove the thin grains and small impurities in the seeds; the roller socket selection mainly plays the role of removing impurities, short grains, and half grains; specific gravity In addition to removing shriveled seeds, light and heavy impurities in the seeds, it can also classify the cleaned seeds. The traditional method of use is to use four cleaning machines with different structures in a single operation, and the quality of seed c...

Problems solved by technology

However, large-scale seed processing enterprises cannot fully adapt to my country's national conditions and economic development. Not only the construction cost is high, but the promotion of seeds is also limited.

In order to overcome the problems existing in the above-mentioned large-scale seed processing enterprises, combined with the level of my country's agricultural development and the needs of actual production operations, the applicant of this patent has studied a mobile four-in-one seed processing machine tool. However, due to the overall technological process configuration The structure is unreasonable, coupled with the problems and deficiencies in the structural design of some operating parts and assemblies, the quality of the seed selection operation still needs to be improved, and the loss rate of the seed operation needs to be reduced
