Description
(1) technical field
The utility model is related to a kind of " a device multirow " formula metering system, belongs to agricultural machinery seeding apparatus.
(2) background technology
With the progress of science and technology, requirement of the modern agriculture to seeding machinery is：Operating speed is improved, increases operation width
Width, develops integration of operation, promotes precise sowing technology.And China is broadcast using " a device a line " formula sead feeder mostly at present
Kind, if improving operating speed, it is easily reduced planting quality；If increasing working width, need to be equipped with multiple feed mechanism for seeds,
Easily cause complete machine structure too fat to move, road is poor by property.Pneumatic type sowing have the advantages that wound kind less, versatility it is good, but mesh
Before also need to constantly improve and optimize, for example：The direction of motion suddenly change of gas, easily produces vortex, viscous flow etc. unfavorable
Factor, and then influence the uniformity of seeding；For distributor, one's own profession broadcast leakage is not only resulted in when a line is blocked,
The amount of broadcasting of other each rows can also be influenceed.
(3) content of the invention
The deficiency existed for current China's seeding machinery, the utility model provides a kind of " a device multirow " formula seeding system
System, the utility model is used cooperatively with existing " a device multirow " formula seeder, high-speed job can be met, and can be prevented effectively from
The influence of the unfavorable factors such as vortex, viscous flow.The utility model realizes seed using air-flow as carrier by first order air flow distribution system
Evenly distribute, complete " a device multirow " formula seeding.
A kind of " a device multirow " formula metering system, including seed-box, feed mechanism for seed, blower fan and first order air flow distribution system.
Described first order air flow distribution system includes distributor, bellows and ejector.Described first order air flow distribution system
System is made using lucite material.
Described distributor is made up of dispenser cap and distributor body, and dispenser cap is used for sealed distributor housing；
Distributor body surrounding is uniformly provided with out kind of a mouth, and the quantity for going out kind of mouth is corresponding consistent with sowing line number, the dispenser cap bottom
In circular cone inclined-plane；Distributor body porch dispenser cap passes through the movable connection of screw thread with distributor body.
Described ejector upper end is connected by bellows and distributor；Nozzle and ejector pass through the movable company of screw thread
Connect, the relative altitude between nozzle and feed pipe is adjustable；Described nozzle lower end and blower fan connection；Ejector by feed pipe with
Feed mechanism for seed is connected；The feed mechanism for seed is located at below seed-box, and the seed in seed-box enters jet pipe through feed mechanism for seed.
The utility model mainly has the advantage that：
1st, air-flow single order distribution system using lucite material make, with transparency it is high, lightweight, easy to process,
The advantages of cleaning facilitates, is conducive to being visually known flowing of the seed in distribution system, allocation situation.
2nd, each row discharge capacity uniformity of air-flow single order distribution system and its interior seeding uniformity of row largely depend on
In the shape and structural parameters of distributor, therefore the utility model devises the dispenser cap with circular cone inclined-plane, and by having
The connection that screw thread realizes dispenser cap and distributor body " precession shaft shifting " formula is processed on machine glass material, following work can be played
With：First, reduce vortex, viscous flow phenomenon that gas kind mixed flow is produced in distributor chamber；Second, circular cone inclined-plane can take up point
With indoor seeding blind area space, guiding seed is conducive to enter discharging tube；3rd, dispenser cap is by way of precession shaft is moved
Air-flow single order distribution system is installed to, it is both simple to operate, easy to loading and unloading, axiality can be effectively ensured again, it is to avoid because assembling is missed
Distribution uneven phenomenon caused by poor.
3rd, the nozzle and ejector below first order air flow distribution system realize " precession shaft shifting " formula by processing screw thread
Connection, this connection is had an advantage that：First, convenient disassembly is flexible；Second, it is relative between nozzle and feed pipe by adjusting
Highly, both can easy cleaning is remained in first order air flow distribution system after unit completion work seed, can adjust again
Relative altitude between nozzle and feed pipe, is conducive to the mixing of gas and seed.
The utility model requires not tight to the appearance and size of seed, it is not necessary to which selected classification, versatility is good, and each row discharge capacity
The uniformity coefficient of variation is less than 3%, meets Standard.

(5) embodiment
The utility model belongs to agricultural machinery seeding apparatus, mainly includes feed mechanism for seed 3, first order air flow distribution system 1, wind
The grade part of machine 4.First order air flow distribution system 1 is made using lucite material, mainly includes distributor 7, bellows 6, jet
The grade part of device 5.It is commercially available part unless otherwise specified in the present embodiment.
The first order air flow distribution system 1 processed by lucite passes through the feed pipe 12 and nozzle that are disposed below
11, it is connected respectively with feed mechanism for seed 3 and blower fan 4.Distributor 7 is made up of dispenser cap 9 and distributor body 8, in distributor body
8 surroundings uniformly process kind of mouth 10, and the quantity for going out kind of mouth 10 is consistent with sowing line number, can be according to sowing line number setting.
During utility model works, the seed in seed-box 2 enters feed mechanism for seed 3, by feed mechanism for seed 3 by seed by integration
For individual, uniform kind subflow is formed, under gravity, is entered through feed pipe 12 in ejector 5.At the same time, blower fan 4
The air-flow of generation enters in ejector 5 through nozzle 11, after being mixed with seed, by going out kind of mouth 10 after reaching distributor 7 through bellows 6
Discharge, realizes evenly distributing for seed, completes " a device multirow " formula seeding.
