Problems solved by technology

[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 fillin

Example Embodiment

[0013] Example 1: The double scoop-wheel opposed high-speed corn precision metering device includes: a left casting half shell 8 and a right casting half shell 11 are integrally connected by a connecting bolt 18 to form an integral seed metering device. The seeder housing is a split structure and is fixed on the frame. The left seeder assembly 1 and the right seeder assembly 12 are installed in the housing. Said seed metering device assembly is connected by a seeding shaft 6 to the left and right seeding device components into a whole, the middle is positioned by a step on the seeding shaft, and the two sides are respectively connected to the left seeding device assembly 1 and the right to the outside. Seeding device assembly 12, the outer side of the left seeding device assembly 1 and right seeding device assembly 12 are positioned axially by positioning devices 2 and 16, and the left and right seeding devices are connected and supported by the casting shaft 6 On the bearings ...

Example Embodiment

[0016] Example 2: The seed inlet opening on the transparent shell is opened upwards, the transparent movable seeding nozzle 9 and the left inoculation tube 30 have upper and lower openings, and the different holes on the two are connected by split pins 29, and the transparent movable inlet The height of the lower edge of the seed takeover 9 changes to change the amount of seeding. The transparent activity seeding takeover 9 moves up, the seeding quantity increases, and the seed surface improves.

[0017] Benefits:

[0018] 1. Since the two sets of spoon wheels are alternately used for seeding, the speed of the seeding spoon and the seed guide wheel is unchanged, and the hole distance is unchanged, the operating speed can be doubled, and the productivity can be doubled. Seed fertilizers are applied at the same time, and one opener is reduced for each seeding row, which can greatly reduce operation resistance.

[0019] 2. The patent of the present invention adopts a split structure. T...

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...
