Abstract
The utility model relates to a kind of small-sized seed essence amount seed plate, comprises disk body, is provided with flat hole, bolt hole and group pore size distribution district on disk body, and the center of described disk body is provided with flat hole, and periphery, flat hole is provided with bolt hole; Described group pore size distribution district is several, is evenly distributed on the circumferencial direction of disk body, in every a group pore size distribution district, is provided with several suction holes.The utility model has the advantages that: cause the thinning difficulty problem of serious waste seed again from solving small-sized seed artificial broadcast or drilling.Small-sized seed essence amount seed plate and precision sower support the use, and realize the precision drilling machineryization of small-sized seed, not only can save in a large number seed, reduce thinning workload, be convenient to once gather in the crops simultaneously, effectively improve output and the quality of small-sized seed, and can greatly reduce labor intensity.
Description
Technical field
The utility model relates to a kind of seeding parts of agricultural production, and concrete is a kind of small-sized seed essence amount seed plate, is mainly applicable to the small-sized seed essence amount seeding of air-sucking type dispenser.
Background technology
China is a large agricultural country, the granule economic crops such as rape, clover, millet are with its drought resisting, barren-resistant, water application efficiency is high, wide adaptability, yield stability is strong, the features such as fertilizer and pesticide consumption is few are occupied very important status in dry farming, slowly become the pillar crop of northern China arid, semiarid zone Developing Sustainable Agriculture.And the sowing of millet, alfalfa seed adopts artificial broadcast or drilling mostly at present.Peasant is for catching full stand, makes that the small-sized seed amount of broadcasting is large, density is large, thinning is difficult.Both caused seed serious waste, time-consuming taking a lot of work again, reduces productivity ratio.Therefore development and employing mechanization precision drilling are extremely urgent.Small-sized seed essence amount seed plate and precision sower support the use, and can realize the precision drilling machineryization of small-sized seed, not only can save in a large number seed, reduce thinning workload, be convenient to once gather in the crops simultaneously, effectively improve granule crop yield and quality, and can greatly reduce labor intensity.The precision drilling of small-sized seed is numerous agriculturists and mass peasants' an urgent demand, is also the active demand of agricultural production.
Summary of the invention
For overcoming the defect of prior art, the utility model provides a kind of small-sized seed essence amount seed plate, the technical solution of the utility model is: 1, a kind of small-sized seed essence amount seed plate, comprise disk body, it is characterized in that, on disk body, be provided with flat hole, bolt hole and group pore size distribution district, the center of described disk body is provided with flat hole, and periphery, flat hole is provided with bolt hole; Described group pore size distribution district is several, is evenly distributed on the circumferencial direction of disk body, in every a group pore size distribution district, is provided with several suction holes.
Described suction hole is 3, and 3 suction holes evenly arrange in group's pore size distribution district.
Described suction hole is 4, and 4 suction holes evenly arrange in group's pore size distribution district.
Described suction hole is 5, and one of them suction hole is positioned at group circle centre position in pore size distribution district, and all the other suction holes are distributed on group circumference in pore size distribution district.
Described group pore size distribution district is 6-24, is evenly distributed on group hole central distribution circle.
Described flat hole entirety is rectangular, and wherein the two ends on relative both sides are connected smoothly by circular arc respectively.
The utility model has the advantages that: cause the thinning difficulty problem of serious waste seed again from solving small-sized seed artificial broadcast or drilling.Small-sized seed essence amount seed plate and precision sower support the use, and realize the precision drilling machineryization of small-sized seed, not only can save in a large number seed, reduce thinning workload, be convenient to once gather in the crops simultaneously, effectively improve output and the quality of small-sized seed, and can greatly reduce labor intensity.

Embodiment
Further describe the utility model below in conjunction with specific embodiment, advantage and disadvantage of the present utility model will be more clear along with description.But these embodiment are only exemplary, scope of the present utility model are not formed to any restriction.It will be understood by those skilled in the art that and do not departing under spirit and scope of the present utility model and can the details of technical solutions of the utility model and form modified or be replaced, but these amendments and replacement all fall in protection domain of the present utility model.
Referring to Fig. 1 to Fig. 3, the utility model relates to a kind of small-sized seed essence amount seed plate, comprises disk body 5, is provided with flat hole 1, bolt hole 4 and group pore size distribution district 2 on disk body 5, and the center of described disk body 5 is provided with flat hole 1, and 1 periphery, flat hole is provided with bolt hole 4; Described group pore size distribution district 2 is several, is evenly distributed on the circumferencial direction of disk body 5, in every a group pore size distribution district 2, is provided with several suction holes 3; Described group pore size distribution district 2 is 6-24, is evenly distributed on group hole central distribution circle 6.Described flat hole 1 entirety is rectangular, and wherein the two ends on relative both sides are connected smoothly by circular arc respectively.
As shown in Figure 1, described suction hole is 3, and 3 suction holes evenly arrange in group's pore size distribution district.
As shown in Figure 2, described suction hole is 4, and 4 suction holes evenly arrange in group's pore size distribution district.
As shown in Figure 3, described suction hole is 5, and one of them suction hole is positioned at group circle centre position in pore size distribution district, and all the other suction holes are distributed on group circumference in pore size distribution district.
Operation principle of the present utility model is: small-sized seed essence amount seed plate and precise seeder support the use, small-sized seed essence amount seed plate is connected on seeding unit by bolt hole, essence amount seed plate one side is connected with seed chamber, opposite side is connected with gas distribution plate, gas distribution plate another side is connected with vacuum chamber, joins by air inlet tube, degree of admission elbow and fan induced draught mouth.When blower fan work, make vacuum chamber produce negative pressure, and then make the both sides of essence amount seed plate produce pressure differential, under the effect of negative pressure, seed in seed chamber is attracted on group hole, seed wheel rotation when operation, the seed of absorption produces vacuum chamber, and suction disappears, seed falls by deadweight, in grain conductor is fallen kind of ditch.Seed wheel continues rotation, and suction hole enters vacuum chamber again, absorbed seed again under the effect of pressure differential, and so continuous circulation reaches seeding object.
According to agriculture requirement, can precision drilling millet, the small-sized seed such as rape, clover, select according to the physical characteristic of seed that group's hole count is 3,4,5, n, the seed plate that aperture is 0.8～1.5mm, when sowing, there is 3-n grain seed in every cave.
