Air tube equipment suitable for corn plot precision seeding

Abstract

The invention discloses air tube equipment suitable for corn plot precision seeding, and relates to the technical field of plot corn seeding. An air pipe is connected to a fan through a pipe; one endof each seed metering pipe is arranged on the air pipe; one end of each seed removing pipe is arranged on the air pipe; a hollow cavity is arranged in each seed metering device, and a seeding hole isarranged in the bottom end of each seed metering device; seed suction pipes and seed drop pipes are located on the same side of the seed metering devices; each seed removing box communicates with theother end of one corresponding seed removing pipe for collecting seeds; a rotating disk is arranged in a hollow cavity of each seed metering device, and each rotating disk is provided with a circle ofseed holes for adsorbing seeds; and each scraping plate is used to scrape down the seeds on one corresponding rotating disk and make the seeds move along the scraping plate to slide out from the seeding hole in the bottom of one corresponding seed metering device. The equipment has the beneficial effects of improving the seed metering precision and seed removing precision of a corn plot precisionseeder, reducing the seed mixing rate of the corn plot precision seeder, reducing the affect on seed metering and seed removing due to different wind power and wind directions, and improving the accuracy of corn plot seeding tests through the structural design.

Description

technical field [0001] The invention relates to the technical field of corn plot breeding, in particular to an air duct device suitable for precision sowing in corn plots. Background technique [0002] In recent years, as my country has gradually increased its emphasis on the breeding of improved corn varieties, it has gradually increased investment and research in the field of seed industry machinery. Although some breakthroughs have been made in the research on key technologies of domestic corn plot planting machinery and equipment, the seeding device still has problems such as low sowing accuracy and easy mixing of seeds, resulting in low accuracy of corn plot experiments after sowing, which seriously affects corn breeding. The improvement of the level, especially in the aspect of the blower device, the airflow direction and wind direction in the blower have an important influence on the process of seed arrangement and clearing.
