Cell seed breeding precise seed discharge device of trefoil seed clearing, changing and discharge method

Abstract

The invention relates to a cell seed breeding precise seed discharge device of a trefoil seed clearing, changing and discharge method. The device is applicable to field seed breeding testing on soybeans, corn and peanuts. The device comprises a seed discharge rear shell assembly, a gear type seed discharge disc, a seed discharge front shell assembly and a driving assembly. An air sucking seed discharge technique is used, and a motor is adopted as a power source. Before seeding, a user inputs expected plant spacing into a system, a seed discharge motor is controlled by a control system to drivethe seed discharge disc to rotate at a uniform speed, single seed sucking is ensured by using a seed clearing mechanism, and precise single seed sowing is achieved; when seeds are cleared, a seed changing mechanism is driven by a seed chamber motor to rotate, different seeding cells contact different seed chambers, and residual seeds are automatically cleared in a circulation manner, new varieties can be supplied, and meanwhile the rotation speed of a seed discharge motor is controlled to be adaptive to different seed spacing of seeds; by adopting the seed discharge device, the problem that excessive labor is needed as artificial seed clearing and change are implemented in the breeding experiment process can be effectively solved, and accuracy and science of scientific seed breeding testing can be ensured.

Description

Technical field: [0001] The invention belongs to the field of agricultural machinery automation, and specifically relates to an air-suction precision seeding device suitable for field breeding experiments of soybeans, corns, and peanuts, which can automatically change seeds, clear seeds and arrange seeds without stopping the machine between each sowing plot. Plant and adjust plant spacing. Background technique: [0002] my country is a large agricultural country, and food security is an important foundation for the country's stable development. The cultivation of high-yielding varieties is an important factor in increasing crop yields. Paying attention to the breeding of excellent varieties of crops is of great significance for achieving stable and high yields. Experimental breeding to develop stable and high-yield crop varieties is the most effective solution to stably increase absolute yield and increase economy, which makes the work of soybean breeding experiments more a...

Problems solved by technology

At present, in the process of breeding experiments in my country, traditional manual sowing is still used. This method is not only inefficient but also unbalanced in seeding quality.

Although some scientific research institutions in China have carried out corresponding research on this problem, because they have not made corresponding innovations on the background of the important topic of plot breeding experiments, they are only used for simple extension of the seed meter for field sowing, reducing the Part of the manual labor force cannot automatically clear and change seeds between each plot, and has not fundamentally solved the problems of cumbersome sowing procedures and uneven seeding quality in the plots, and cannot guarantee the accuracy and scientificity of breeding experiments
