Specific embodiment
The following examples illustrate the utility model, but is not intended to limit the scope of the present invention.
Embodiment 1
Referring to Fig. 1~3, which includes kind of a storehouse 1, seed extraction disk 5, negative pressure device and elastic packing disk
11, the lower part side in kind storehouse 1 offers seed and extracts mouth, and seed extracts disk 5 and is fixedly connected with main shaft 10 and is rotatably arranged on kind
Son extracts mouth, and elastic packing disk 11 is arranged to be extracted between disk 5 and kind storehouse 1 in seed, and elastic packing disk 11 and seed extract disk 5 and consolidate
Fixed connection, seed extract and are uniformly provided with multiple first seed drawing holes 6 on disk 5, are correspondingly provided with second on elastic packing disk 11
The other side that seed extracts 5 relative resilient seal disc 11 of disk, negative pressure device and kind storehouse is arranged in seed drawing holes 12, negative pressure device
1 is relatively fixed, and negative pressure device is that the first seed drawing holes 6 and second seed drawing holes 12 provide negative pressure and make seed in kind of storehouse 1
Be attracted at second seed drawing holes 12, at least one first seed drawing holes 6 be located on the outside of negative pressure device and with big gas phase
Logical, after the seed in kind storehouse 1 is drawn into second seed drawing holes 12, seed extracts disk 5 and drives seed by sealing hairbrush 13
1 outside of kind of storehouse is turned to, when the first seed drawing holes 6 that seed extracts disk 5 turns over seal casinghousing 4, negative pressure disappears, seeds fall
Complete sowing.
The diameter of second seed drawing holes 12 is gradually increased along the direction for extracting disk 5 far from seed, this is because seed
Shape is frequently not the spherical of rule, and the elasticity of elastic packing disk 11 is utilized, and seeds having abnormal can be adsorbed onto the
At two seed drawing holes 12, the extraction reliability of seed is further improved, guarantees emergence rate.
