Non-destructive seeding method based on rapid adjustment of seeding amount

Abstract

The invention provides a non-destructive seeding method based on rapid adjustment of a seeding amount. A non-destructive seeding device based on the rapid adjustment of the seeding amount is used to implement seeding, a feeding control mechanism is arranged at the upper part of a box body, a seed brushing mechanism is arranged above a seeding control mechanism, the seeding control mechanism for controlling feeding is installed in the middle part of the box body, a seed protection mechanism is in contact with the seeding control mechanism, and a seed receiving cup is arranged under the box body; and at the same time, a left seed filling channel, a right seed filling channel, a seeding wheel seed filling channel, a seed storage area, a transition area, a seed filling area, a seed brushing area and a seed filling cavity capable of completing rapid adjustment of the seeding amount are formed in the box body through the above structure, and a left cavity cylinder and a right cavity cylinderin a lateral cavity component in the seeding control mechanism can communicate with the seeding wheel seed filling channel after being docked. The volume of the seed filling cavity is adjusted to realize rapid adjustment of the seeding amount, quantified seeds can be received into the seed filling cavity to avoid hard contact with the seed protection mechanism to cause mechanical damage to the seeds, 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 non-destructive sowing method based on rapidly adjusting the sowing amount. Background technique [0002] The performance of the sowing device directly affects the quality of sowing. A good sowing device must have good versatility and be able to adapt to the sowing of large, medium and small grains, beans, pastures and vegetable seeds, and at the same time, the seeds must not be damaged during the working process of the sowing device. At present, most of the seeding devices used on seeders are hole wheels, which mainly rely on the self-weight of seeds to fill the holes of the hole wheel and discharge them by their own weight, such as the high-filling seed meter with patent application number 200420066140.0, and the high-speed seed meter with patent application number 201010032446.4. Precision seed metering device, patent application number is 91219223.2 seeder p...

AI Technical Summary

Problems solved by technology

[0003] 1. Mechanical damage to the seeds, 2. The sowing amount is not accurate enough, 3. The mechanism will cause problems such as seed leakage and intermittent contusion of seeds;

[0004] At the same time relying on the self-weight of the seeds, filling the holes of the wheel and discharging the seeds, which limits the operating speed of the planter, especially after the seeds fill the holes under the action of gravity, the flat seeds are easy to get stuck in the holes, resulting in empty space. holes and short strips; in addition, most of the seed guards used in the current sowing devices are rigid fixed seed guards. The seed guards are used to escort the seeds through the seed protection area, and the seed guards can prevent the seeds from falling from the holes. , but it will also rub the seeds, resulting in a higher rate of seed damage
