Control method for volume-adjustable non-destructive seeding

Abstract

The invention provides a control method for volume-adjustable non-destructive seeding. A volume-adjustable non-destructive seeding device is used to control non-destructive seeding, in the volume-adjustable non-destructive seeding device, a seeding control part and a seed protecting part are respectively arranged in a support, the seed protecting part is in contact with the seeding control part, the interior of the support is provided with a support circular arc section in contact with the seeding control part, and the seeding control part is composed of a seeding wheel main body, a limit adjustment component, a cavity adjustment component, a lateral cavity component, a floating drive component and a drive main shaft; and a left seed filling channel, a right seed filling channel, a seedingwheel seed filling channel and a seed filling cavity which can complete seeding and have adjustable volumes are formed in the support through the above structure, and a left cavity cylinder and a right cavity cylinder in the lateral cavity component can communicate with the seeding wheel seed filling channel after being docked. The limit adjustment component is adjusted to realize dynamic adjustment of a volume of the seed filling cavity, quantified seeds are further received into the seed filling cavity to avoid hard contact with the seed protecting part to cause mechanical damage, so that the non-destructive operation is realized.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a volume-adjustable non-destructive sowing control method. Background technique [0002] The quality of the performance of the sowing mechanism directly affects the quality of sowing. A good sowing mechanism must have good versatility and be able to adapt to the sowing of large, medium and small grains, beans, forages and vegetable seeds, and at the same time, the seeds must not be damaged during the working process of the sowing device. Most of the seeding mechanism used on the seeder is a type hole wheel at present, mainly relying on the type hole of the seed self-weight filling type hole wheel, such as the precision seed metering device of the seeder with the patent application number 91219223.2, which is provided at the lower buckle of the seed box Seed-discharging hole wheel, the hole wheel has leakage holes along the circumference, there is a scraping plate ...

Most of the seeding mechanism used on the seeder is a type hole wheel at present, mainly relying on the type hole of the seed self-weight filling type hole wheel, such as the precision seed metering device of the seeder with the patent application number 91219223.2, which is provided at the lower buckle of the seed box Seed-discharging hole wheel, the hole wheel has leakage holes along the circumference, there is a scraping plate on the hole wheel at the lower opening of the seed chamber, the hole wheel is also equipped with an arc-shaped seed protection cover, the seed metering device The size of the hole wheel can be adjusted by adjusting the speed of the hole wheel or replacing the hole wheel with different apertures. These two methods of adjusting the seed quantity still have shortcomings: by adjusting the speed of the hole wheel, it is necessary to adjust the speed of the hole wheel and the seeder. The rotation speed matches, otherwise the seeder works at a faster speed, but when the rotation speed of the hole wheel is adjusted too high, after the seeds fill the holes under the action of gravity, the flat seeds are easy to get stuck in the holes, resulting in cavities and short strips; At the same time, if it is realized by replacing the hole wheels with different apertures, the machine needs to be disassembled, which not only affects the sowing efficiency, but also affects the service life of the parts; The plate is used to escort the seeds through the seed protection area. The seed protection plate can prevent the seeds from falling out of the hole, but it will also rub the seeds, resulting in a high rate of seed damage
