Abstract
An even seed hole type seed metering wheel is provided with round holes which are arranged in a staggered form according to a spiral line; the linear velocity is reduced by over twice, so that seed filling performance is good, and no positive hole exists; and simple mechanical structure mode is adopted to replace complicated pneumatic type, thereby achieving the effect of accurate sowing.
Description
Affiliated technical field
The utility model relates to the uniform particles discharge device, especially is seed wheel in the seeding unit on the agricultural seeding machine.
Background technology
Seed wheel (dish) on the present known seeding unit, the nest eye is arranged, the hole rollers such as nest pull, centrifugal disc, vertical disc of living, the mass rate of emission that has is slow, efficient is low, the broadcast leakage of easy hole; The cost that has is higher, volume is big, service condition is high, as pneumatic type.Its subject matter and shortcoming are that discharge wheel compares, makes the type hole on the seed wheel to be difficult for filling kind and to produce the hole broadcast leakage under velocity function with land wheel transmission number.The practice of general prejudice strengthens the diameter of discharge wheel, the distance between the extended pattern hole, and essence has accelerated that discharge wheel and land wheel transmission are counted the linear velocity of ratio, are difficult for filling kind, or hole broadcast leakage, reduces linear velocity and could solve the hole broadcast leakage.
Summary of the invention
In order to reduce existing discharge wheel and land wheel drive line speed, features simple structure reaches the Precision Seeding effect, the utility model provide a kind of uniform granule type hole discharging wheel, not only rotating speed low, fill plant, hole not, and can satisfy the land wheel high speed, high-efficiency and precision is sowed needs.
The technical scheme that its technical problem that solves the utility model adopts is: uniform granule type hole discharging wheel, the type hole is circular (shape, size and pm emission adapt), with a kind of shape hole, be arranged by spiral, be staggered between row and the row, ranks shape hole is no less than two (as shown in the figure), 2-6 in four centimeter length discharge wheel delegation shape holes.Compare, increase more than the twice shape hole with the diameter discharge wheel and reduce in the quantity on the discharge wheel, more than the twice with land wheel transmission number and compare linear velocity with existing like this, type hole dense phase sieve, institute's pm emission (seed) on discharge wheel only enter the type hole otherwise the leeway that do not have to exist, and press the type hole and arrange equably in order and discharge.Mainly be used in discharging corn, beans, wheat, Chinese sorghum, millet, vegetable seed, sesame etc.
The beneficial effects of the utility model are, in easy, cheap frame for movement mode, reach the complicated expensive precise sowing effect of pneumatic type.Make, use simple to operate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Figure is the utility model discharge wheel mo(u)ld top half pore structure schematic diagram.
Among the figure 1, discharge wheel, 2, the type hole.
Embodiment
In the drawings, discharge wheel (1) is installed on sower seed-box bottom, its centre bore and feed shaft, axle are installed are rotated and drive a discharge wheel (1) and rotate in seeding unit, the seed in the seed-box enters type hole (2), and arranges discharging equably in order by it.
Claims (4)
1, a kind of uniform granule type hole discharging wheel, type hole are circular, are arranged by spiral, and it is characterized in that: be staggered between row and the row, ranks shape hole is no less than two.
2, according to the described uniform granule type hole discharging wheel of claim 1, it is characterized in that: arrange with a kind of shape hole.
3, according to the described uniform granule type hole discharging wheel of claim 1, it is characterized in that: 2-6 in 4 centimeter length discharge wheel delegation type holes.
4, according to the described uniform granule type hole discharging wheel of claim 1, it is characterized in that: mainly discharge corn.
