Description
Technical field
The utility model belongs to agricultural machinery, and in particular to machine drags dry crop seeder.
Background technology
Before this, dry crop opens bunch planting kind, is essentially all manually to be carried out using hand-held formula seeder of interrupting, labour is strong
Degree is big, and farming efficiency is low, and what is occurred in recent years carries the seeder for the drum-type tractor-drawn for opening cave gear piece using circumference, but
Because seed is from seed-box to the Song Zhong mechanisms for falling into kind of cave, the basic structure in the seeder still used without departing from artificial seeding,
It send kind that slow, failure is more, and can quickly open the operating rate of the roller gear piece formula point opener in cave and mismatch, card type, no often occur
It spits kind or seed is fallen outside cave, seeding quality is problematic.
The extraction of accidental aspirated-air type single seed, transmission, the Song Zhong mechanisms launched, work on the seeder of trench digging live streaming
Smooth, not scarce grain, frequency are high, but are all to have a style of one's own to be arranged on seeder, and opposite plough is respectively independent.Since bunch planting is ploughed
Making to there are problems that out cave and send the precise coordination of kind so that aspirated-air type Song Zhong mechanisms also fail to configure on the seeder of bunch planting,
Cave rolling is opened with gear piece formula to cooperate with, improve the speed and precision for opening bunch planting kind with it.
Utility model content
The purpose of this utility model is to provide a kind of air-aspiration type hole sowing precision planter, is used for the bunch planting of dry crop, gram
Take the existing seeder above shortcomings that cave is opened with roller gear piece.
