A volume-adjustable non-destructive seeding control method

Abstract

A volume-adjustable non-destructive sowing control method, which uses a volume-adjustable non-destructive sowing device to control non-destructive sowing. In the volume-adjustable non-destructive sowing device, the sowing control part and the seed protection part are respectively arranged in the bracket, and the seed protection part and the sowing control part contact, the bracket is provided with a bracket arc section in contact with the sowing control part, and the sowing control part is composed of the main body of the sowing wheel, the limit adjustment component, the cavity adjustment component, the horizontal cavity component, the floating drive component and the drive spindle; at the same time In the support, there are left seed filling channel, right seed filling channel, sowing wheel seed filling channel and seed filling cavity that can complete the adjustable sowing volume through the above structure. The cavity can be connected to the seeding wheel filling channel after being docked; the volume of the filling cavity can be dynamically adjusted by adjusting the limit adjustment component, and the quantified seeds can be further stored in the filling cavity to avoid hard contact with the seed protection part Cause mechanical damage, so as to achieve non-destructive operation.

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 performance of the seed meter directly affects the quality of sowing. A good seed metering device 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 should not be damaged during the working process of the seed metering device. Most of the seed metering devices used on the seeder are shaped hole wheels at present, mainly relying on the hole of the self-weight filling type hole wheel of the seeds, such as the precision seed metering device of the seeder that the patent application number is 91219223.2, which is provided at the lower buckle of the seed box. There is a seed-discharging hole wheel, and the hole wheel has leaking holes along the circumference. There ...

Most of the seed metering devices used on the seeder are shaped hole wheels at present, mainly relying on the hole of the self-weight filling type hole wheel of the seeds, such as the precision seed metering device of the seeder that the patent application number is 91219223.2, which is provided at the lower buckle of the seed box. There is a seed-discharging hole wheel, and the hole wheel has leaking holes along the circumference. There is a seed scraper 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 size of the amount can be realized by adjusting the speed of the hole wheel or replacing the hole wheel with different apertures. These two ways 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 sowing Otherwise, the operating speed of the seeder will be matched, but when the speed of the hole wheel is adjusted too high, the flat seeds will be easily stuck in the hole after the seeds fill the hole under the action of gravity, 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 seed protection plate is used to escort the seeds through the seed protection area. The seed protection plate can prevent the seeds from falling from the hole, but it will also rub the seeds, resulting in a high rate of seed damage
