Description

A kind of machinery and aspiration convolution feed mechanism for seed
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
It is an object of the invention to overcome the deficiencies in the prior art, there is provided a kind of energy saving, reduction wound plant a degree, take kind Stability is high, fill the high machinery of seeding accuracy and aspiration convolution feed mechanism for seed.
For achieving the above object, technical scheme provided by the present invention is:It includes seed sowing shell, aspiration housing, method Orchid, seed wheel, feed shaft and seeds sucker, wherein, seed wheel and seeds sucker are placed on flange admittedly, three be sandwiched in seed sowing shell and Between aspiration housing, feed shaft is sequentially each passed through aspiration housing, flange, seeds sucker, seed wheel and seed sowing shell, drives method Orchid, seeds sucker, seed wheel synchronous axial system;The seed sowing shell is provided with and fills kind of a space, aspirated-air type conveying cavity and mechanical defeated Cavity, aspirated-air type is sent to convey cavity and extend to mechanical conveying cavity bottom from mechanical conveying cavity top end around semi-circumference, fill Plant and be spatially located at aspirated-air type conveying cavity bottom side, and connect with aspirated-air type conveying cavity;The mechanical conveying Cavity lower end is provided with mouth of charging seed, and upper end is provided with and conveys the connected entrance that cavity is connected with aspirated-air type, clear kind is provided with the connected entrance and is filled Put and seeds scraper, connected entrance is located between cleaning device and seeds scraper, and seed wheel is placed in mechanical conveyor chamber body;The aspiration Housing is by bearing mounting base and is shaped in the aspiration cavity at bearing mounting base edge and constitutes, aspiration cavity opened with outward 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 by being placed in therebetween Seeds sucker is separated, and is connected by the suction hole on seeds sucker.
Further, the seed wheel circumferential surface is uniformly distributed the chute for transporting seed for rotation, the chute Correspond with the suction hole on seeds sucker.
Further, there is gap between the seed wheel and mechanical conveying cavity inner wall.
Further, the aspiration housing is offered for installing seeds sucker near the end that aspirated-air type conveys cavity Step.
Further, the aspirated-air type conveying cavity bottom is provided with and unloads kind of a plate.
Further, the seeds scraper adjustable-angle.
Compared with prior art, this programme using air-suction seeding unit kind of a mode of filling, and mechanical seed sowing device takes Kind mode, can reduce the aspiration cavity of air-suction seeding unit, prevent air-suction seeding unit from taking during kind due to mechanical oscillation etc. Reason produces impact to 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 need for by the way of positive force feed kind, blowing to the seed on discharge plate, saving The energy.
