Description
Technical field
The present invention relates to the technical field of agricultural seeder machinery, more particularly to a kind of machinery and aspiration convolution seeding
Device.
Background technology
A kind of planting type that direct sowing of rice is referred to not to carry out seedling, transplant and seed is directly sowed at land for growing field crops.Large area
Direct sowing of rice can save a large amount of labours, alleviate the contradiction of labour's season sexual tension, the lightness, specially to realizing Rice Production
Industry, scale have great significance.
The type of seeding of direct sowing of rice seeder is that seed is sown in paddy field using feed mechanism for seed.Feed mechanism for seed is divided into:Machinery
Formula feed mechanism for seed and air-suction seeding unit.Mechanical seed sowing device is, by seed transport, to carry using sheave or hole roller, is finally put into
Into paddy field.Air-suction seeding unit is to adopt sucker, and seed absorption transport is carried, and is put into afterwards in paddy field.
When filling kind, due to filling kind using sheave or type hole, it is not high that it fills kind of precision to mechanical seed sowing device, it is impossible to well
Control to fill the quantity planted every time, and mechanically belong to rigidity and fill kind, the damage of seed rice is easily caused in seed-filling process, but
Seed rice is filled into after sheave or type hole, is not easily susceptible to the impact of external environment, takes kind of process more stable.
When filling kind, aspiration adsorbs seed on discharge plate to air-suction seeding unit, and its seed-filling process is due to using flexible
Airflow function, therefore the damage to seed is less, and precision is higher, but during taking kind, because air-flow occurs disorder, row
Kind of device can produce mechanical oscillation, and seed rice is easy to from sucker drop, and affect the normal work of feed mechanism for seed, when air-suction seeding unit it is same
When the sucker that works it is excessive, it is necessary to bigger air pressure, need to expend more energy to produce air-flow.
Mechanical seed sowing device and air-suction seeding unit respectively have its pluses and minuses, and the two forms complementary, if the advantage of the two
A kind of new feed mechanism for seed is gathered to form, that is beneficial to the carrying out of direct sowing of rice.
The content of the invention
