Nondestructive sowing method based on rapid adjustment of seeding rate

Abstract

Based on the non-destructive sowing method based on the rapid adjustment of the seeding rate, the non-destructive sowing device based on the rapid adjustment of the seeding rate is used to implement the sowing, wherein the discharging control mechanism is set on the upper part of the box body, and the seed brushing mechanism is set above the sowing control mechanism to control the discharge. The sowing control mechanism is installed in the middle of the box, the seed protection mechanism is in contact with the sowing control mechanism, and the inoculation cup is set under the box; at the same time, the left filling channel and the right filling channel that can quickly adjust the sowing amount are formed in the box through the above structure. channel, sowing wheel seed filling channel, seed storage area, transition area, seed filling area, seed brushing area and seed filling chamber, and the left chamber cylinder and right chamber cylinder in the horizontal chamber assembly in the sowing control mechanism can After docking, it is connected to the seed filling channel of the sowing wheel, and the rapid adjustment of the seeding rate is realized by adjusting the volume of the filling cavity. Secondary 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 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
