Abstract
A circular tube gap type air suction seed sowing device suitable for sowing small-sized crops such as wheat and the like is composed of an outer tube (1), an inner tube and outer tube connecting plate (2), a limiting ring (3), an inner tube (4), a seed feeding sheet (5), a seed protecting plate (6), a seed box (7) and keys (8). The outer tube can slide along the inner tube axial direction and can not rotate around the inner tube, a gap around the circumference is formed between the end faces of the adjacent outer tubes in a limiting ring limiting mode, the inner tube is connected with the fan, air holes are formed in the wall of the inner tube, when the fan works, negative pressure is generated in the outer tube through air flow, the air flow outside under the action of the negative pressure flows in through the gap, when the gap passes through the seed box, the air flow contacts with the seeds and adsorbs the seeds, and when the seeds rotate to the lower portion of the outer tube, the seeds are discharged through the seed throwing sheets inserted.
Description
Affiliated technical field
The present invention relates to a kind of dispenser of sower in the agricultural machinery
Background technology
At present the seeding unit that sower is commonly used is divided into two kinds of mechanical type and pneumatic types, and the mechanical type seeding unit is common grooved pulley type and indent type etc.The pneumatic type seeding unit is divided into air-sucking type and air-sweeping type again.Air-suction seeding unit commonly used in the production is mainly used in the sowing corn, and the seeding unit of sowing wheat mostly is fluted-roller feed mechanism, and fluted-roller feed mechanism is simple in structure, and cost is low, and reliable operation is easy to adjust, can satisfy general sowing requirement; But for pursuing high yield and then seeding quality being required under the higher situation, fluted-roller feed mechanism is because the pulsating nature of its seeding has adverse effect to seeding uniformity.And the disk air-suction seeding unit that is used to sow big grain crop such as corn is unsuitable for sowing granule crops such as wheat, and therefore, it is good to develop a kind of seeding quality, is applicable to that the dispenser of granule crop sowing such as wheat has important practical significance.
Summary of the invention
The invention provides a kind of circular tube clearance type air-suction seed-sowing device of sowing granule crops such as wheat that is applicable to, this device can be realized evenly seeding continuously.
The technical solution adopted for the present invention to solve the technical problems is: with the main shaft of pipe in as this dispenser, the outer line number of sowing as required of interior pipe is with several outer tubes, outer tube can not rotate around interior pipe to sliding along interior tubular axis, limit by spacing ring between adjacent outer tube end face, keep certain clearance, form slit around circumference.Interior pipe links to each other with blower fan, and ventilation hole is arranged on the inner tubal wall, and when blower fan was worked, air communication was crossed ventilation hole and made generation negative pressure in the outer tube, and the air-flow of outside flows into through the slit under suction function.During the sower walking, under drive wheel, outer tube rotates with interior pipe, contacts with seed and seed is taken out of when the slit process is planted case, when the seed that is adsorbed turns to the outer tube below, realizes seeding by the sheet of charging seed that inserts the slit.
The invention has the beneficial effects as follows: owing to adopted the slit to inhale kind, can sow small-sized seeds such as wheat continuously equably, owing to adopted the plug-in type sheet seeding of charging seed, the slit can not stopped up again.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Accompanying drawing is a structural map of the present invention
1. outer tubes among the figure, 2. inner and outer pipes connecting plate, 3. spacing ring, 4. in pipe, the sheet of 5. charging seed, 6. seeds protecting plate, 7. kind of case, 8. key.
Embodiment
In the accompanying drawings, circular tube clearance type air-suction seed-sowing device is by outer tube (1), interior pipe (4) is socketed to form, interior pipe (4) is an elongated pipe, on interior pipe (4) wall ventilation hole is arranged, inner and outer pipes connecting plate (2) is welded in outer tube (1) inwall, and can endwisely slip along interior pipe (4) but can not rotate around interior pipe (4) by the restriction of key (8), the inner and outer pipes connecting plate is opened pore on (2), several outer tubes (1) are by the spacing arrangement of spacing ring (3), make the slit (width in slit can be regulated by changing spacing ring (3) according to the size of seed) that forms certain width between adjacent outer tube (1) end face, charge seed end of sheet (5) and seeds protecting plate (6) is fixing, the other end inserts in the slit between adjacent outer tube (1), seeds protecting plate (6) is kind of the base plate of case (7), and in place, corresponding slit fluting, the outer end of outermost two outer tubes (1) and interior pipe (4) sealing.During work, manage in (4) in the blower fan air intake duct inserts, the ventilation hole that air communication is crossed interior pipe (4) makes the inside of outer tube (1) produce negative pressure, the air-flow of outside is in the inflow pipe of slit under suction function, during the sower walking, under drive wheel, outer tube (1) is along with interior pipe (4) rotates, when planting case, slit rotation process contacts with seed, because the air-flow that the inside and outside pressure differential in slit produces will be planted seed in the case (7) and will be adsorbed on the slit between outer tube (1), along with outer tube (1) rotates, the seed that is adsorbed is taken out of kind of a case (7) and is turned to the below with outer tube (1), by the sheet of charging seed (5) that inserts the slit seed is discharged.
Claims (2)
1. circular tube clearance type air-suction seed-sowing device, by outer tube, the inner and outer pipes connecting plate, spacing ring, interior pipe, the sheet of charging seed, seeds protecting plate is planted case and key and is formed, and it is characterized in that: by the slit absorbed seed between adjacent outer tube end face.
2. circular tube clearance type air-suction seeding unit according to claim 1 is characterized in that: realize seeding by the sheet of charging seed that inserts the slit.
