Description
Technical field
The utility model belongs to agricultural mechanical field, is specifically related to a kind of seeding unit for seeding machinery.
Background technology
Sowing is a basic link of agricultural.The quality of seeding quality is by the height problem of emergence rate after having influence on.Along with the development of modern technologies, the technical merit of sower also further improves.Especially present precision planter has saving breeding, and without thinning, Precision Seeding field plant is evenly distributed, and reaches rational close planting, is beneficial to the advantage of seedling growth.Simultaneously Precision Seeding saves time, economizes the effect of merit and volume increase in addition.Therefore precise sowing has become main trend now, and its critical component is seeding unit.
At present, seeding unit is mainly divided into two large classes: mechanical seed sowing device and Pneumatic seeding apparatus.Widely used is side-feeding seeding unit in mechanical seed sowing device, and this seeding unit is made up of housing and seed plate, has several seed-filling holes at seed plate cylindrical, has structure simple, the features such as seed damage ratio is low.But its weak point is that seed pack completeness is low, and operating speed is slow.
Summary of the invention
The purpose of this utility model is intended to overcome above-mentioned shortcoming, provides the precision seeder that a kind of structure is simple, seed pack completeness is high, operating speed is fast.
For achieving the above object, the utility model adopts following solution: a kind of precision seeder, comprise housing, seed plate, seed plate is arranged in housing, around its axis rotation, can it is characterized in that: chimes dish cylindrical has several seed-filling holes, and seed-filling hole turns forward, the normal shape of its center line and seed plate has angle, crossingly with chimes dish end face after seed-filling hole form double wedge, inclined-plane is from low to high set before seed-filling hole.
Above-mentioned precision seeder, is characterized in that: described housing installs click resonator, and one end of click resonator is fixed on housing, and the other end arranges elasticity and knocks hammer, knocks on inclined-plane that hammer is pressed on before seed plate seed-filling hole.
Above-mentioned precision seeder, is characterized in that: the angle that the center line of described seed-filling hole and the normal of chimes dish are formed is 2
o-50
o.
Above-mentioned precision seeder, is characterized in that: the bevel depth that described seed-filling hole is arranged above is 1mm-5mm.
Above-mentioned precision seeder, it is characterized in that: described click resonator is made by by steel wire, comprise canned paragraph, resilient deformation section and knock hammer, canned paragraph is fixed on housing by bolt by pressing plate, knocks hammer and is pressed on the inclined-plane before seed plate seed-filling hole by resilient deformation section.
During utility model works, seed plate rotates along clockwise direction in housing, seed-filling hole on chimes dish is in the Chong Zhong district below housing, seed is filled in seed-filling hole, when knocking hammer through click resonator, seed is knocked hammer and pushes away to smear and enter bottom seed-filling hole, knock hammer to be taken up by the double wedge on seed plate simultaneously, after double wedge turns over and knocks hammer, seed plate is knocked under knocking the elastic force effect of the resilient deformation section of hammer on click resonator, make seed plate produce vibration, promote that the seed-filling hole in Chong Zhong district carries out filling kind.
The effect on the inclined-plane on seed plate allows double wedge position surface, and the hammer that knocks being conducive to click resonator is taken up by double wedge, makes again the double wedge surfaced have baler function simultaneously, can scoop to seed-filling hole by seed, strengthen and fill kind of a trend.
The center line of the seed-filling hole on seed plate and the angle of chimes dish normal have following effect: one is the baler function strengthening double wedge; Two is the component impelling the seed in seed-filling hole to produce movement in hole in motion process, improves filling reliability; Three is make knocking to hammer into shape and pushing away that to smear direction consistent to seed of the incline direction of seed-filling hole and click resonator, makes seed more easily be pushed away to smear and enter bottom seed-filling hole.
Compared with prior art, the utility model tool has the following advantages:
1, the utility model is provided with the seed-filling hole of inclination on seed plate, and the seed-filling hole of inclination has baler function, can strengthen and fill kind of a trend, improves filling reliability; Particle is piled with around seed-filling hole, particle is piled to filling in seed-filling hole under pressure effect at the particle produced because of gravity, and is knocked seed plate by click resonator, makes it produce simple harmonic oscillation, extremely strong facilitation can be produced to filling, pack effectiveness and filling velocity are improved.Therefore, the utility model can improve seed pack completeness and operating speed, thoroughly improves the broadcast leakage phenomenon of side-feeding seed wheel sower.
2, the utility model structure is simple, is easy to manufacture, and production cost is low.
3, the utility model seed damage ratio is low.
