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 seedings
Device.
Background technology
Direct sowing of rice refers to without seedling, a kind of planting type transplanted and seed is directly sowed to crop field.Large area
Direct sowing of rice can save a large amount of labours, alleviate the contradiction of labour's season sexual tension, to realizing the lightness, specially of Rice Production
Industry, scale have great significance.
The type of seeding of direct sowing of rice seeder is that seed is sown into 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 that seed transport is carried, finally put into using sheave or hole roller
Into paddy field.Air-suction seeding unit is to use sucker, and seed, which is adsorbed transport, to be carried, and is put into paddy field later.
Mechanical seed sowing device is when filling kind, and due to filling kind using sheave or type hole, it is not high to fill kind of precision, cannot be well
The quantity of kind is filled in control every time, and is mechanically belonged to rigidity and filled kind, the damage of seed rice is be easy to cause in seed-filling process, still
After seed rice is filled into sheave or type hole, it is not easily susceptible to the influence of external environment, it is more stable to take kind of process.
When filling kind, seed is adsorbed on discharge plate air-suction seeding unit by aspiration, and seed-filling process is due to using flexible
Airflow function, it is therefore smaller to the damage of seed, and precision is higher, but during taking kind, since air-flow will appear disorder, row
Kind device will produce mechanical oscillation, and seed rice is easy to fall from sucker, influences the normal work of feed mechanism for seed, when air-suction seeding unit is same
When the sucker that works it is excessive, it is necessary to the air pressure of bigger needs to expend more energy to generate air-flow.
Mechanical seed sowing device and air-suction seeding unit respectively have its advantage and disadvantage, the two to form complementation, if the advantages of both handles
A kind of new feed mechanism for seed is gathered to form, that is beneficial to the progress of direct sowing of rice.
Invention content

Cavity lower end is provided with mouth of charging seed, and upper end is provided with the communication port being connected to aspirated-air type conveying cavity, clear kind of dress is equipped at the communication port
It sets and seeds scraper, between cleaning device and seeds scraper, seed wheel is placed in mechanical conveyor chamber body communication port；The aspiration
Shell is by bearing mounting base and is shaped in the aspiration cavity at bearing mounting base edge and forms, aspiration cavity opened with outside
The connected suction hole of air pump is connect, meanwhile, the aspiration cavity is corresponding with aspirated-air type conveying cavity, and the two is between the two by being placed in
Seeds sucker is separated, and is connected by the suction hole on seeds sucker.
Further, the seed wheel circumferential surface is uniformly distributed for rotating the chute for transporting seed, the chute
It is corresponded with the suction hole on seeds sucker.
Further, there are gaps between the seed wheel and mechanical conveying cavity inner wall.
Further, the aspiration shell is offered close to the endface of aspirated-air type conveying cavity for installing seeds sucker
Step.
Further, the aspirated-air type conveying cavity bottom, which is equipped with, unloads kind of a plate.
Further, the seeds scraper adjustable-angle.
Compared with prior art, this programme fills taking for kind of mode and mechanical seed sowing device using air-suction seeding unit
Kind mode, can reduce the aspiration cavity of air-suction seeding unit, due to mechanical oscillation etc. during preventing air-suction seeding unit from taking kind
Reason has an impact the stability for taking kind of process, reduces the wound kind situation of mechanical seed sowing device seed-filling process, increases mechanical
Feed mechanism for seed fills the precision of sowing, while without the mode of positive force feed kind, being blowed to the seed on discharge plate, saves
The energy.
