Abstract
The invention discloses a high-speed precise seed sowing device, belonging to agricultural machinery. A type hole wheel and friction discs are coaxially and rotatably installed on a shell, the friction discs are fixedly arranged at both axial sides of the type hole wheel, pressure plates are fixedly installed on the shell and are installed between the friction discs at intervals and above the type hole wheel, the distance between the pressure plates and the type hole wheel is gradually reduced along the rotation direction of the type hole wheel, and the pressure plates are made of elastic materials; a seed guide plating and a seed inlet are fixedly installed at the right upper side of the shell, the seed guiding plate has an included angle of 30-60 degrees with a plane and is tangent with a bristle wheel, and the seed inlet is contacted with and arranged at the right upper side of the seed guide plate; and an observation plate is fixedly installed at the left upper side of the shell and made of transparent materials. The device has simple structure, enables seeds to be pressed by making use of the friction of the friction discs and the type hole wheel to the seeds, increases the filling force of the seeds and the filling speed and satisfies the requirements of high-speed and precise seed sowing.
Description
Affiliated technical field
The invention belongs to agricultural machinery.
Background technology
Seeding machinery is one of tool of production the most basic in the agricultural production, and seeding unit is the critical component of seeding machinery.The mechanical type seeding unit has simple in structure, reliable operation, low cost and other advantages, but mainly relying on seed to conduct oneself with dignity, the mechanical type seeding unit comes filling hole roller type hole, limit the speed in seed packed type hole, influenced the seeding unit dropping frequency, limited the operating speed of sower.
Summary of the invention
The purpose of the invention is exactly the problem that exists at above-mentioned prior art, a kind of high-speed precise seed sowing device is provided, rely on frictional disk and hole roller that the frictional force of seed is made the seed pressurized, active force when increasing seed filling hole roller type hole, improve the seed filling velocity, reach the high speed and precision seeding, satisfy the agriculture requirement that existing sower is sowed at a high speed.
The purpose of the invention can realize by following scheme: a kind of high-speed precise seed sowing device comprises that housing and configuration are installed in hole roller on the housing, brush-wheel, seed-pretecter, plant device, seeding sprocket wheel, hairbrush sprocket wheel, drive sprocket clearly.Hole roller and frictional disk are coaxial to be installed in rotation on the housing, axial both sides at hole roller all fixedly are fitted with frictional disk, pressing plate is packed on the housing, be fitted between the frictional disk platen gap, and be fitted in the top of hole roller, the distance of pressing plate and hole roller reduces gradually along the rotation direction of hole roller, and pressing plate is made by elastomeric material.
Lead kind of plate and enter the upper right side that kind of hole is packed in housing, leading kind of plate and horizontal plane angle is 30 °～60 °, and tangent with brush-wheel, advances kind of a hole contact and is fitted in the upper right side of leading kind of plate.Access panel is packed in the upper left side of housing, and access panel is made by transparent material.
The beneficial effect of the invention is: simple in structure, cost is low, and is easy to use and reliable, and the dropping frequency height satisfies the requirement of sower high speed operation.

Embodiment
Below in conjunction with drawings and Examples the invention is further specified.A kind of high-speed precise seed sowing device comprises that housing 4 and configuration are installed in hole roller 1 on the housing 4, brush-wheel 8, seed-pretecter 9, plant device 10, seeding sprocket wheel 11, hairbrush sprocket wheel 12, drive sprocket 13 clearly.Hole roller 1 and frictional disk 2 coaxial being installed in rotation on the housing 4, axial both sides at hole roller 1 all fixedly are fitted with frictional disk 2, pressing plate 3 is packed on the housing 4, pressing plate 3 is fitted between the frictional disk 2 with gap, and be fitted in the top of hole roller 1, the distance of pressing plate 3 and hole roller 1 reduces gradually along the rotation direction of hole roller 1, and pressing plate 3 is made by elastomeric material.
Lead kind of plate 7 and enter the upper right side that kind of hole 6 is packed in housing 4, leading kind of plate 7 is 30 °～60 ° with horizontal plane angle, and tangent with brush-wheel 8, advances 6 contacts of kind of hole and is fitted in the upper right side of leading kind of plate 7.Access panel 5 is packed in the upper left side of housing 4, and access panel 5 is made by transparent material.
During operation, seed enters in the seeder unit shell 4 by entering kind of hole 6 and leading kind of plate 7 in the sowing machine case, drive sprocket 13 provides powered rotation by sower, make coaxial hairbrush sprocket wheel 12 drive seeding sprocket wheel 11 and rotate, make simultaneously with the coaxial brush-wheel 8 of hairbrush sprocket wheel 12 with coaxial frictional disk 2 and the hole roller 1 of seeding sprocket wheel 11 and rotate by chain.When frictional disk 2 and hole roller 1 rotates to the frictional force of seed, make seed in the space that frictional disk 2, hole roller 1 and pressing plate 3 constitute, form the seed flow that is under pressure, thereby reduce the speed in the relative hole roller of seed 1 type hole, increase the pressure of seed to hole roller 1, thereby increase kind of the power of filling in seed filling hole roller 1 type hole, improve the seed filling velocity, realize the high-frequency seeding.Access panel 5 adopts transparent material to make, and is convenient to observe the seeding unit working condition.
This seeding unit, simple in structure, cost is low, and is easy to use and reliable, and the dropping frequency height satisfies the requirement of sower high speed operation.
