Description

A kind of precision rice direct-seeder seed wheel

Technical field

The present invention relates to a kind of a kind of precision rice direct-seeders that can disposably complete the Precise sowing operation to rice Seed wheel.

Background technology

Rice originates in Tropical Asian, is annual gramineae plant, 24 chromosomes.After China widely plants, gradually It travels to all over the world.Rice claims rice or rice after tying grain of rice decladding.Nearly half population in the world, all using rice as food；Mesh Before, China relies primarily on manually the seed discharging operation of rice.

But the mode of this artificial growth rice, virtually add the production cost of enterprise；Labor strength Greatly, and efficiency is very low, is not suitable for planting on a large scale, and a variety of drawbacks determine that artificial growth rice seriously constrains rice industry Sustainable development.

The content of the invention

In order to overcome the problems, such as the labor intensity of artificial growth rice is big, efficiency is low etc., the present invention provides a kind of rice precision amount Seed wheel is broadcast live in cave.

The technical solution adopted by the present invention to solve the technical problems is：

The precision rice direct-seeder seed wheel includes seed spout, seeder unit shell, seeds protecting plate, brush kind wheel, the second seed feeding chamber, kind Case, the first seed feeding chamber, chain, seed, seed wheel, it is characterised in that：During work, seed is entered the first of feed mechanism for seed by seed inlet Seed feeding chamber, the seed of the first seed feeding chamber is in self gravitation, upper layer seed pressure and with entering type under the action of seed wheel frictional force Hole；When seed wheel goes to the second seed feeding chamber, the seed taken out of by seed wheel accumulated herein and brushed down by brush kind wheel Seed may proceed to be charged into type hole；When type hole enters Qing Zhong areas, extra seed blows into the second seed feeding chamber by brush kind wheel and enters shield kind Area；When type hole goes to bottom opening, seed departs from type hole under the action of cleaning device and enters defeated kind by dead weight Pipe, falls earthward, and realizes seeding.

Combined fertilizing, which gives anti-block apparatus, includes cutaway disk knife, supports cutting plate, applicator boot, sowing and ditching Device, it is characterised in that：Spade uses rigid structure, lower tilt, and oblique spade is conducive to stalk and is slided along spade, and journey is slipped over upper In, coordinate by the breaking cutting disc between two spades is goed deep into the support plate on spade, that completes stalk has support to cut, and prevents It blocks.

Air-suction seed metering device structure includes outer tube, and inner and outer pipes connecting plate, spacing ring, inner tube, piece of charging seed, seeds protecting plate, plants case stirs Wheel, stirs axis, gear, it is characterised in that：Inner tube is the main shaft of feed mechanism for seed, several outer tubes, outer tube and inner tube set are cased with outside inner tube It connects, there is venthole on inner tubal wall, outer tube is connected with inner tube by inner and outer pipes connecting plate, and stomata is opened on inner and outer pipes connecting plate； It charges seed one end of piece and seeds protecting plate is fixed, in the gap between other end insertion outer tube, seeds protecting plate is the bottom plate of plants case, and in correspondence It slots at gap, outer tube both ends and the interior seal of tube stir axis in plants case and driven by outer tube by gear.

The invention has the advantages that the precision rice direct-seeder seed wheel disposably completes the operations such as Precise sowing, tool There are high production efficiency, mechanization degree height, labor intensity of operating staff is small, equipment life is long, compact-sized, easy to manufacture, work The features such as making reliable, conveniently moving and application easy to spread.
