Abstract

A non-destructive sowing mechanism based on dynamic volume adjustment, wherein the sowing control part and the seed protection part are respectively arranged in the bracket, and the seed protection part is in contact with the sowing control part, and a bracket arc section in contact with the sowing control part is arranged in the bracket , 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, a left filling mechanism that can complete the dynamic volume adjustment is formed in the bracket through the above structure. The seed channel, the right seed filling channel, the seeding wheel seed filling channel and the seed filling chamber, and the left and right chamber tubes in the horizontal chamber assembly can be connected to the seeding wheel seed filling channel after being docked. In the present invention, the seed filling chamber can obtain the required seeding amount by adjusting the limit adjustment assembly, and can discharge all the seeds in the seed filling chamber to achieve the technical effect of completely clearing the seed; and it does not need to be dismantled or replaced Any parts can effectively improve the seeding efficiency and prolong the service life of parts.

Description

technical field

[0001] The invention relates to the technical field of agricultural machinery, in particular to a non-destructive sowing mechanism based on dynamic volume adjustment. 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 circumfer...
