Double-bucket-wheel opposite type high-speed precise corn seeding device

Abstract

The invention belongs to the technical field of agricultural machinery, which is used for solving the problem that an existing bucket wheel seeding device in high-speed operation is poor in seeding quality, and designs a double-bucket-wheel opposite type high-speed precise corn seeding device. The seeding device comprises a seeding device shell, seeding device components and a seeding shaft, wherein the seeding device shell is of a split symmetrical structure, and is integrally fixed on a rack; left and right seeding device components comprising seed guiding wheels, baffles and seeding bucket wheels are combined integrally by the seeding shaft; the baffles are installed between the seed guiding wheels and the bucket wheels; transparent semi-shells with movable seed charge guide pipes and the left and right seeding device components form a left seed chamber and a right seed chamber; to-be-sown seeds enter the seed chambers via the seed charge guide pipes from a seed box, and scoops of the bucket wheels discharge seeds uniformly. The double-bucket-wheel opposite type high-speed precise corn seeding device is used for sowing hole sowing crops at high speed, such as corn, peanuts, soybeans, or two crops are sown alternatively; synchronous fertilization of seed manure for micro element fertilizers and successive alternative synchronous fertilization of seed manure also can be achieved without generating the phenomenon of seedling burning due to mixing of seed manure.

Description

technical field [0001] The double-spoon-wheel-opposite high-speed corn precision metering device belongs to the technical field of seed metering devices for agricultural machinery seeders, and specifically relates to a coaxially rotating scooping scoop that is evenly crossed and staggered left and right on two scoop wheels. The right two rows of scoop wheels and the seed meter corresponding to the seed guide wheel. Background technique [0002] The spoon wheel type seed metering device is the most widely used mechanical corn precision seed metering device at present. The existing spoon wheel type seed metering device has the following disadvantages: First, the seed metering device is a single row of spoon wheels. Restricted, the number of scoops evenly distributed on the circumference cannot be further increased. When the corn sowing distance is determined, the rotation speed of the seed meter is proportional to the forward speed of the unit. The rotation speed of the spoon...

[0002] The spoon wheel type seed metering device is the most widely used mechanical corn precision seed metering device at present. The existing spoon wheel type seed metering device has the following disadvantages: First, the seed metering device is a single row of spoon wheels. Restricted, the number of scoops evenly distributed on the circumference cannot be further increased. When the corn sowing distance is determined, the speed of the seed meter is proportional to the forward speed of the unit.

The rotation speed of the scoop wheel greatly affects the quality of sowing, too high a speed will make the filling performance and cleaning performance worse

Therefore, the operating speed of the corn seeder using the seed meter is low, generally 3-4km / h, resulting in too low productivity

The second is that the size and position of the seed inlet of the current spoon-wheel seed metering device are fixed, and the amount of seed feeding cannot be controlled. The amount of seed feeding affects the height of the seed surface in the seed chamber. The quantity is too high, the seed surface is too high, and it is unfavorable to clear the seeds. When sowing seeds of different grain sizes, it is necessary to adjust the amount of seeds
