Selection of land, the top edge of the demarcation strip 17 and turn to its rear it is described stir between kind of the front end face for stirring kind of tooth of wheel 5 away from
From for 1mm.
The seeds protecting plate 18 and the mated condition of discharge plate 2 and type hole plug-in unit 3 are as shown in Figure 10.Due to the first arc section 26
With the rake of the second arc section 27 and the first side wall 20 of type hole plug-in unit 3 and second sidewall 21 towards outside the circumference of discharge plate 2
The edge of edge is close to cooperation, and the second arc section 27, relative to the first arc section 26, the inclination angle of rake becomes larger, width becomes
Narrow, when discharge plate 2 rotates, the second arc section 27 removes the extra corn seed in the type hole 23 of type hole plug-in unit 3, ensures simple grain
Rate.
The course of work of the present invention is as follows:
The rotation band dynamic metering plate 2 of axis 4 rotates, the rotation of discharge plate 2 drive four type hole plug-in units 3 being attached thereto and
5 rotation of kind of wheel is stirred, seed enters from seed input pipe 16 with air-flow, is filled with the type hole plug-in unit 3 for turning to lower end.Type hole plug-in unit 3 with
And under the clamping action of seeds protecting plate 18, the seed for being filled with type hole plug-in unit 3 rotates therewith, when turning to 2 surface of feed mechanism for seed, by
In the circumference towards discharge plate 2 of the rake and type hole plug-in unit 3 of the first arc section 26 and the second arc section 27 of seeds protecting plate 18
The opening of outer rim is bonded, and the second arc section 27, relative to the first arc section 26, the inclination angle of rake becomes larger, width narrows,
It is only capable of accommodating single seed in type hole plug-in unit 3 at this time, extra seed is under the action of the holding power of seeds protecting plate 18 and air-flow
It does centrifugal movement and is detached from type hole plug-in unit 3, be thrown to 6 internal face of procapsid and slide go back to feed mechanism for seed bottom along demarcation strip 17, stirring
Kind wheel 5 and airflow function under converges with the seed for having just enter into feed mechanism for seed 2, carry out again fill kind.
The single seed left in type hole plug-in unit 3 continues to rotate with type hole plug-in unit 3, until the second circular arc of seeds protecting plate 18
Section 27.Without the package of seeds protecting plate 18, seed has lacked holding power, and type hole plug-in unit 3 is detached under self gravitation effect, along
Feed mechanism for seed is discharged in planting mouth 19, completes entire seeding process.
Specific embodiments of the present invention are explained in detail above in conjunction with attached drawing, but the present invention is not limited to above-mentioned realities
Example is applied, it within the knowledge of a person skilled in the art, can also be without departing from the purpose of the present invention
Various changes can be made.
