Description
Technical field
The present invention relates to crop seeding equipment technical fields, specially a kind of for water used in rice precision drilling
Rice precise hole sowing integrated arranging roller.
Background technique
Sowing is the primary link of agricultural production, and the quality for sowing situation not only extremely has an impact to the growth of crops,
It also directly determines its total output, therefore realizes that sowing seeds technology has big facilitation to China's agricultural development.With me
The development of state's agricultural machinery technology, country buys peasant household the subsidy policy of agricultural machinery in addition, and more and more peasant households turn from plantation by hand
Become mechanical planting, and the dispenser of seeding machinery directly determines the seeding quality of feed mechanism for seed.Countries in the world are all very
Pay attention to sowing seeds technology, developed country has also all realized the precision drilling of big or middle grain crop substantially, and abridged edition effect is very aobvious
It writing, China is directed to big or middle crops sowing seeds technology also comparative maturity at present, but for being similar to the small-sized seeds such as rape
And the seed that the shapes such as rice are special, technology need to be improved.
Rice is one of main cereal crops in China, national more than 3 200 ten thousand hm of Monitoring of Paddy Rice Plant Area2, account for about national total
The 14% of cultivated area accounts for the 20% of world's Monitoring of Paddy Rice Plant Area.Total output is the 34% of the world, is ranked first in the world, at present China
Agricultural is faced with the period of history changed from traditional agriculture to modern agriculture, and Mechanization In Rice Sowing And Planting is important composition portion
Point.Rice feed mechanism for seed in China's is mostly that cannot realize rice precision amount cave well from the transformation of the feed mechanism for seeds such as corn and soybean at present
Seeding technique is primarily present the problems such as structure is complicated, flow rate is inaccurate and waste seed.
Summary of the invention

Wall connection.
The rice precise hole sowing integrated arranging roller rotates under the action of feed shaft fixing seat 3, and seed is in seeding type hole 2
Inclination front seed is disturbed under the action of 21, rice paddy seed pressure will be attached to pressure under the action of positive pressure gas flow
On aperture 23, each pressure aperture 23 is corresponding to press an attached rice paddy seed, then 3 pressure apertures 23 in seeding type hole 2 press attached 3
Grain rice paddy seed realizes that 1 seeding type hole 2 accommodates 3 rice paddy seeds；It tilts front and is conducive to rice along 21 seeding type hole 2
Seed enters, and kind of a performance is filled in raising.Then, rice paddy seed is completed to take kind of a process under the action of positive pressure gas flow pressure is attached, in rice
Seed is taken to area of charging seed under the rotary action of precise hole sowing integrated arranging roller, the inclination back edge of this region seeding type hole 2
Be conducive to rice paddy seed to launch, to realize the precise hole sowing of 3 rice paddy seeds.
There are 6 column type hole bands, the 6 rows sowing in corresponding field, to realize one on the rice precise hole sowing integrated arranging roller
A 6 row of rice precise hole sowing integrated arranging roller seeding；Contain 10 seeding type holes 2, each cave of corresponding every row on each column type hole band
The distance between.
Working principle of the invention is as follows: as shown in Figure 1, seeding type hole the invention mainly comprises cylinder wall 1 and its above
2, under the action of external seeding driving force, the cylinder wall 1 rotates under the action of feed shaft fixing seat 3 and supporting rib 4；Water
Rice is located at the area Chong Zhong, and seed disturbs rice paddy seed under the action of the inclination front of seeding type hole 2 is along 21, positive pressure gas flow by
External air pump provides, and will be attached to rice paddy seed pressure on pressure aperture 23 under the action of positive pressure gas flow, each pressure aperture 23
Corresponding to press an attached rice paddy seed, then 3 pressure apertures 23 in seeding type hole 2 press attached 3 rice paddy seeds, realize 1 seeding
Type hole 2 accommodates 3 rice paddy seeds；Rice paddy seed is completed to take kind of a process under the action of positive pressure gas flow pressure is attached, in rice precision amount cave
It broadcasts and takes seed to area of charging seed under the rotary action of integrated arranging roller, the inclination back edge of this region seeding type hole 2 is conducive to
Rice paddy seed is launched, to realize the precise hole sowing of 3 rice paddy seeds.There are 6 column on the rice precise hole sowing integrated arranging roller
Type hole band contains 10 seeding type holes 2 on each column type hole band, to realize 6 rows of sowing, the corresponding hill spacing of the seeding type hole 2
It can be realized by adjusting the revolving speed of rice precise hole sowing integrated arranging roller.The workflow of the rice precise hole sowing integrated arranging roller
Journey are as follows: determine rice precise hole sowing integrated arranging drum rotation speed --- air pump provides positive pressure gas flow --- external drive rice precision amount cave
Broadcasting the rotation of integrated arranging roller, --- seeding type hole 2 disturbs seed, and --- pressure attached water rice --- takes kind --- charging seed --- circulation
Seeding process --- complete 6 row rice paddy seed bunch plantings.
The present invention, which works, is embodied effect: rice feed mechanism for seed in China's solved by the invention is mostly by corn and soybean etc.
Feed mechanism for seed transformation, cannot realize rice precise hole sowing kind technology well, be primarily present that structure is complicated, flow rate is inaccurate
The problems such as with waste seed.The present invention realizes 6 row precise hole sowing water of a feed drum seeding by the way of integrated arranging roller
Rice effectively improves working efficiency and seeding precision.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, the essence of technical solution of the present invention is not departed from
