Technical field
This utility model is related to a kind of workpiece of sowing machine operation, specifically a kind of millet essence amount discharge plate, mainly
Suitable for vertical disc air suction type seeder millet seeding operation.
Background technology
Millet as China's important special crop of agricultural, have the advantages that to be of high nutritive value and Dietotherapy health effect,
The northern area of China cultivated area is larger, but millet seeding operation Mechanization sowing degree is relatively low, millet Mechanization sowing operation
Mostly drilling, not only serious waste seed, and needs more man-hour carries out thinning operation, so development millet mechanization essence amount
Sowing is for the great significance of China's millet farming.Millet precision drilling operation, is the urgent needss of agricultural production.
The content of the invention
This utility model provides a kind of suction and plants stable, cavitation preferable millet essence amount discharge plate during whereabouts, it is adaptable to hang down
Straight disc air suction type seeder millet seeding operation.
The technical solution of the utility model is：A kind of millet essence amount discharge plate, including circular disk body, it is characterised in that
The power transfer hole coordinated with the drive shaft of feed mechanism for seed is provided with the center of the disk body, is provided with the periphery of the power transfer hole
Multiple installing holes being uniformly distributed along the circumference, in the periphery of the installing hole multiple suction holes being uniformly distributed along the circumference are provided with, and the suction hole cuts
The both sides in face are two involute sides being parallel to each other, and the involute guide line in the middle of two involute sides is with seeding disk center
Circle be one section of involute of basic circle, the two ends in suction hole section are circular arc, and the length on involute side is more than semi arch
Diameter；The suction hole band is tapered.
The length in described suction hole section is 3-6mm, and the spacing on two involute sides is 0.8-2mm.
The circular arc semi arch at the two ends in described suction hole section, between a diameter of two involute sides of the semi arch
Away from.
The taper taper of described suction hole is 15 ° -45 °.
The number of described suction hole is 10-30.
Described power transfer hole is positive six ribs hole.
This utility model is supported the use with vertical disc air suction type seeder, and its suction hole guide line is involute, can be subtracted
Mutual collision when few Millet Seed is fallen by suction hole, cavitation preferably, takes kind of a better performances, can carry out millet essence amount and broadcast
Operation is planted, seed can be saved, millet farming workload is reduced, improved farmers' income.

Specific embodiment
Further describe this utility model with reference to specific embodiment, advantage of the present utility model and feature will be with
Description and it is apparent.But these embodiments are only exemplary, do not constitute any restriction to scope of the present utility model.
It will be understood by those skilled in the art that can be to this utility model skill under without departing from spirit and scope of the present utility model
The details and form of art scheme is modified or is replaced, but these modifications and replacement each fall within protection domain of the present utility model
It is interior.
Knowable to Fig. 1 and Fig. 2, this utility model includes seeding disc main body 5, suction hole 1, power transfer hole 4 and screw 3.
As shown in Fig. 2 equidistant line segment of the suction hole involute sideline 11 for involute guide line 12, two involute sidelines
11 is equal with the distance of involute guide line 12.The connection circular arc 13 in two involute sidelines 11 is semicircle, and the radius of semicircle is
Involute sideline 11 and the distance of involute guide line 12, circular sliding slopes reduce the corner angle quantity of suction hole 1, reduce Millet Seed and break
Loss rate.
Operation principle of the present utility model is：Millet essence amount discharge plate is supported the use with vertical disc air suction type seeder,
Discharge plate is connected by screw 3 using bolt and kind of a wheel is stirred.Positive six prismsby power transfer hole 4 on discharge plate and feed mechanism for seed axle
Positive six prismsby part connects, and carries out discharge plate power transmission.Millet essence amount seeding
It is negative pressure chamber between disk upside and feed mechanism for seed back casing, the lower end of discharge plate is atmospheric pressure；Discharge plate opposite side with
It is seed chamber between feed mechanism for seed procapsid.During work, discharge plate provides power and carries out fixed-axis rotation by feed mechanism for seed axle, and blower fan is negative
Pressure chamber provides negative pressure, and negative pressure is delivered to seed chamber by the involute flute profile cone angle hole 1 on millet essence amount discharge plate, due to pressure
Difference effect produces suction to the Millet Seed of seed chamber.Negative-pressure sucking makes seed adsorb on the feed outlet 1 of discharge plate and with row
Discharge plate is rotated together, is completed to inhale and is planted and take kind of an operation；When seed turns to lower end atmospheric pressure region with discharge plate, seed it is negative
Pressure suction disappears, and falls in grain conductor by gravity, completes a suction hole seeding operation.Discharge plate fixed-axis rotation, each
The so continuous cycle operation of suction hole 1, reaches the purpose of millet precision drilling.
Agriculture requirement is sowed according to millet, the number for selecting suction hole 1 is 10-30, is selected according to the physical characteristics of millet
Select suction hole width（2D）For 0.8-2mm, length L is 3-6 mm, and taper is 15 ° -45 °.
