Abstract
The invention discloses a kind of roller aspiration array precise seeders.The equipment is characterized in that: being connect on the left of air duct (3) with blower, the left side shaft shoulder simultaneously covers roller side cover plate (5), gas chamber is connected to by 5 suckers with air inlet in roller, it forms air duct (3) open type sector and inhales kind of a chamber, seed guiding groove (6) uniformly paves seed at array stomata uniformly distributed on the outside of roller, convenient for the absorption of seed, when the seed being adsorbed at the sucker of roller (10) outer surface turns to air duct (3) closed covering of the fan, at this time since aspiration negative pressure disappears, seed will fall off the leading in kind of hole of seeding frame (9), complete the essence amount seeding of seed.Compared with vertical table roller and double-arc spline driven sucking precise measuring device.Draught fan matching power consumption is few, and corresponding air delivering pipeline and its structure are simple, and feed mechanism for seed forced vibration influence is small, and seeding effect and operation quality are easily controllable.
Description
Technical field
The invention belongs to agricultural machinery technological field more particularly to a kind of roller aspiration array precise seeders.
Background technique
With the development of Modern Agricultural Machine, driven sucking precise seeder is with operating efficiency height, the good spy of seeding quality
Property, be widely used, current feed mechanism for seed to large size, high speed, multirow developing direction be main research tendency.It uses at present
Vertical table roller and double-arc spline suction precision hill planter draught fan matching and corresponding air delivering pipeline, its structure is complicated, and right
Blower and power delivery request are higher, and energy consumption is high；Since matched tractor dynamic power is generally lower, when mating multirow, multiple groups circle
When disk aspiration operation simultaneously, mechanomotive force wretched insufficiency is sowed；And existing mechanical hill-drop feed run is because to shape of the seed size
It is required that stringent, forced vibration influences greatly, and seeding effect and operation quality are difficult to control.Therefore, feed mechanism for seed cannot accomplish a cave one
Grain or two, cave seeding operation, can not accomplish precision drilling at the phenomenon that often will appear more an of cave or hole.
Summary of the invention
The object of the present invention is to provide a kind of roller aspiration array precise seeder, with solve existing vertical table roller,
The problems such as double-arc spline air-suction seeding unit, fan energy consumption is big, structure is complicated, planting quality is poor.
The technical solution adopted by the present invention to solve the above technical problem is: roller aspiration array essence amount seeding of the present invention
Device, the feed mechanism for seed composition: air duct (3), roller side cover plate (5), seed guiding groove (6), seeding frame (9), roller (10)；Feed mechanism for seed is total
At being installed on rack (1), air duct fixed frame (2), seeding frame (9) are fixed on rack (1) through screw group, holding screw (4)
Air duct (3) is rigidly connected on air duct fixed frame (2), air duct is stationary.
For the roller aspiration array precise seeder, roller (10) is rigid connection by flat key with sprocket wheel (8),
Sprocket wheel (8) rotation can drive roller (10) to rotate synchronously, and roller is supported on rolling stand (7) by right hand roller bearing (12)
Realize rotary motion.
For the roller aspiration array precise seeder, bearing (11) and roller (10) of the air duct (3) by right side
Connection.
For the roller aspiration array precise seeder, it is connect on the left of air duct (3) with blower, the left side shaft shoulder and roller
Side cover plate is connected, and gas chamber is connected to by 5 suckers with air inlet in roller, forms air duct (3) open type sector and inhales kind of a chamber.
For the roller aspiration array precise seeder, seed guiding groove (6) uniformly paves seed to roller outside
At the array stomata of cloth, convenient for the absorption of seed, when the seed for being adsorbed on roller (10) outer surface is turned back to air duct (3) closed fan
When face, since aspiration negative pressure disappears, seed will fall off the leading in kind of hole of seeding frame (9), complete the essence amount seeding of seed.
Detailed description of the invention
Attached drawing 1 is roller aspiration array precise seeder structural schematic diagram
Attached drawing 2 is feed mechanism for seed sectional view
Attached drawing 3 is that air duct shows that structure is intended to
1. 7. rolling stand of rack 2. air duct fixed frame, 3. air duct, 4. holding screw, 5. roller side cover plate, 6. seed guiding groove, 8. chain
Take turns 9 seeding frame, 10. roller, 11. air duct bearing, 12. roller bearings.
Specific embodiment
As shown in Figure 1, air duct is fixed on static, roller at air duct fixed frame (7) by holding screw (4) by air duct (3)
(10) it is formed and is rigidly connected by flat key with sprocket wheel (8), and transmitted by sprocket wheel (8) to form rotary motion, roller is driven to press
According to certain revolving speed, turned round on rolling stand (7) by roller bearings (12).
As previously mentioned, air duct (3) is that inner cavity is hollow, left side is air inlet, with roller side cover plate (5), shape at the shaft shoulder of left side
Kind of a chamber is inhaled at air duct (3) open type sector, negative pressure is formed by the suction of blower.
As previously mentioned, seed guiding groove (6) uniformly paves seed at array stomata uniformly distributed on the outside of roller, due to blower shape
At negative pressure, seed is attracted in the sucker of roller (10) surface when being evenly distributed with sucker by array on roller (10), when being adsorbed on
When seed at the sucker of roller (10) outer surface turns to air duct (3) closed covering of the fan, since negative pressure disappearance seed will fall off row
Kind frame (9) is led in kind of hole, and the essence amount seeding of seed is completed.
Finally, it is stated that embodiment of above is only used to illustrate the technical scheme of the present invention and not to limit it, although reference
Present invention innovation is described in detail in better embodiment, those skilled in the art should understand that, it can be to this
The technical solution of innovation and creation is modified or equivalent replacement, without departing from the objective and range of the present invention program, because containing
Lid is in the scope of the claims of the present invention.
