Analysis of Seed Injuring Protection Mechanism on Wheat Precision Seedmeter with Ball-spoon Shaped Inner-cell
(0) Wheat precision seedmeter of ball-spoon shaped inner-cell (patent number: ZL98244378.1)solves the difficult problem of wheat precise seed. The seedmeters seeding element is double-hole and seeds fill the double-hole with cooperation of multi-forces. It can control the seed-rate of wheat accurately, and it is better than other wheat seedmeter in accuracy of seed-rate and uniformity of seeding.It is a new breakthrough in structure and technology of the vertical-plate feed of seed-cell filling on inside seedmeter applied to tillering crop. There isnt any unit for cleaning, scraping and pushing seeds in its structure, and it cleans unnecessary seeds by gravity. So the seeds discharged by the seedmeter should not be injured. From the experiment results of the seed-plate, the seed-injuring rate is higher than the index of the national standard. How to reduce the rate is the main problem. In the paper, according to the developing and blazing new trails made in the study of the seed-plate, the seed-injuring protection mechanism is analyzed starting with the Seed-injuring conditions and causes. Proceeding from the test of the seedmeter, parameter and structure is optimized to reduce the seed-injuring rate.
