Classification table for seed selecting machine

Abstract

The invention discloses a classification table for a seed selecting machine and aims to solve the problem that a sieve of an existing classification table is prone to deformation after being used for a long time. The classification table comprises an inclined framework type classification table body. A vibration motor used for driving the classification table body to vibrate back and forth is arranged in the lateral direction of the classification table body. A sieve is arranged in the framework of the classification table body. A gridding type rib plate is arranged in the framework of the classification table body and located on the lower portion of the sieve, and the upper portion of the rib plate abuts against the lower portion of the sieve. The upper portion of the classification table body is provided with an upper sealing cover communicated with an air sucking pipe. A plurality of seed outlet grooves are formed in the lateral direction of the classification table body. A lower sealing cover is arranged on the lower portion of the classification table body, a plurality of rows of classification baffles are arranged on a bottom plate of the lower sealing cover, and a seed falling passage is formed between every two adjacent classification baffles. The seed outlet grooves correspond to the seed falling passages. The bottom plate of the lower sealing cover is provided with outlets located in the falling passages, and all the outlets are communicated with a seed receiving hopper.

Description

technical field [0001] The invention relates to a classifying table for a seed sorting machine. Background technique [0002] Seeds are usually screened for storage. Seed screening is divided into primary selection and selection. The primary selection usually uses a primary cleaning machine to remove large and light impurities in the seeds. The selection uses a selection machine, which is to further press the seeds by density sorted by size. [0003] The main structure of the existing seed sorting machine includes a feed hopper, a pneumatic system connected with the feed hopper to suck the seeds into the grading table and provide wind power for the grading table, a grading table for sorting the seeds according to density and size and A hopper connected to the grading table. The main disadvantages of the above-mentioned seed selection machine are: 1. Usually only one layer of screen is set in the grading table. After long-term use, the screen surface is easily deformed, an...
