Specific implementation mode
Aspirated-air type sunflower discharge plate is further described with the following Examples.
As illustrated in fig. 1 and 2, the aspirated-air type sunflower discharge plate of the present embodiment, including circular disk body 5, the one of 5 periphery of disk body
Circle is equipped with multiple suction holes 3 along its circumference uniform distribution, and the number of suction hole 3 is preferably between 18 to 20.In each suction
It is equipped with positioned at the position of the orifice edge of suction hole 3 on 5 surface of disk body between kind hole 3 and 5 center of circle of disk body and leads kind of item 4.It is all
It leads kind of item 4 all and is from the outwardly extending triangular prism in 5 surface of disk body, it is identical that these lead 4 size of kind of item, parallel with 5 surface of disk body
Triangular cross section is all the isosceles triangle that apex angle is 30 °, and each kind of item 4 of leading is arranged on its corresponding suction hole 3
Position it is also all consistent.The longest edge for leading the triangular cross section of kind of item 4 is close to the side of suction hole 3, this side is vertical
Line in 3 center of circle of suction hole to 5 center of circle of disk body.
Wherein, as shown in Figure 1, each kind of item 4 of leading positioned at it towards next leading kind along 5 periphery of disk body is anticlockwise
The side of item 4 is leading edge, and the leading edge and above-mentioned next suction hole 3 led corresponding to kind of item 4 are tangent, and is preferably drawn
Guide margin is tangent close to the side in 5 center of circle of disk body with suction hole 3.The presence of leading edge makes the kind for being drawn onto 5 centre position of disk body
6 (shown in Fig. 3) of son will not be easily drawn onto on suction hole 3, and multiple seeds 6 is avoided to fall into the then quilt of the same suction hole 3
Planting causes seed 6 to waste to identical position.
Wherein, the middle part of disk body 5 is equipped with the power transfer hole 2 to be rotated with dynamic metering plate for installing drive shaft, moves
Power transfer hole 2 is positive six rib hole, and periphery is equipped with multiple mounting holes 1 for installing disk body 5.
Wherein, as shown in Fig. 2, leading the thickness that the height that kind of item 4 extends from 5 surface of disk body is less than discharge plate, kind of item 4 is led
It should not be arranged blocked up, be damaged to avoid seed 6 from rubbing on leading kind of item 4 during being adsorbed to suction hole 3.
3 edge of each suction hole of the aspirated-air type sunflower discharge plate, which is designed with, leads kind of item 4, and seed 6 is being adsorbed to suction kind
During on hole 3, by the barrier for leading kind of item 4 to be adjusted to the posture that 6 middle part of seed as shown in Figure 3 is adsorbed.
The area that seed 6 bears suction under the posture that middle part is adsorbed is maximum, thus the absorption of seed 6 is stablized, is not easy in transmission process
It falls off；The side rather than top or bottom end of seed 6 downward, can smoothly fall in sowing cave, be not easy to deviate when whereabouts, at
Cave property is preferable.The sunflower seeding operation of batch can be carried out using the aspirated-air type sunflower discharge plate, reduces farming workload, saved
Time.
