Description
Technical field:
The present invention relates to the technical field of seeders of agricultural machinery, relate in particular to the structure of a kind of seeding unit on sower.
Background technology:
Many crops, economic crops or grass seed profile are different, and volume mass difference is large, and epidermis is smooth, and precision drilling difficulty is larger, and seeding machinery is had relatively high expectations.At present, the sowing of the crops such as the clover in the areas such as the most of mountain area of China, terraced fields, cover farming, rape, wheat is manually to sow as main, operating efficiency is low, sow inhomogeneous, percentage of seedgermination is low, seed is not only wasted seriously, and plant strain growth is mixed and disorderly, brings difficulty to the mechanized harvest of herbage, economic crops and crops etc.Existing external recessing versatility is good, but discharge capacity precision and uniformity are poor; The seeding precision such as common cell-seed distributor or friction-type seeding unit are high, but versatility is poor, and adaptability is not strong.Thereby it is good to research and develop a kind of versatility, strong adaptability, the amount of broadcasting can smartly be measured the multi-functional indent type precise seeder of controlling and seem particularly important.
Summary of the invention:
The present invention is directed to the weak point that prior art exists, provide a kind of versatility good, the amount of broadcasting is easy to adjust reliable, the multi-functional indent type precise seeder that adjusting range is large, thus efficiently solve problems of the prior art.
The present invention realizes by the following technical solutions: a kind of multi-functional indent type precise seeder, include the seeds discharging box being connected on kind of case, and power input shaft, rotor, broadcasts quantity regulating device; It is characterized in that: the described quantity regulating device of broadcasting includes traveller, spring, spring base, tapered fine setting push rod, wing nut, trimming handle, end cap and securing member.
Described rotor outer surface is provided with the nest eye of depression, and nest intraocular is provided with traveller; Described power input shaft one end and rotor are affixed by key, are set with seeds discharging box, tapered fine setting push rod and trimming handle on the other end.
Described tapered fine setting push rod one end is by the trimming handle that has been threaded of long 8～20mm, and the other end is fixed with circular cone slippery fellow, middle part be threaded end cap and wing nut, and two parts screw thread being provided with does not communicate; End cap is fixed on seeds discharging box by securing member.
In the eyes, the other end slides on the foxy outer surface of circular cone the nest that described traveller one end is arranged on rotor depression.Described indent amount amount is 1～8, and diameter is φ 3～φ 20mm, is 1.5～15mm deeply.
Described circular cone slippery fellow is arranged between rotor internal cavity and end cap, 15 °～60 ° of its cone angles, and outside diameter is φ 20～φ 80mm, inside is made as cavity; Described rotor diameter is φ 30～φ 90mm, and rotor outer surface and seeds discharging box inwall gap are 0.1～0.3mmo
Described seeds discharging box is inlaid with and plants clearly dividing plate entering kind of a port, and seed inlet inwall is provided with kind of a brush, and it is back taper horn mouth that shell goes out kind of port.
The multi-functional indent type precise seeder of described one, is characterized in that: one or more multi-functional indent type precise seeders are housed on power input shaft, and two ends are by bearings in frame, and its one end is provided with the logical handwheel of adjusting.
The invention has the beneficial effects as follows: the present invention is according to all kinds of agriculture requirements without awns grass seed or crops, economic crops sowing, provide the one amount of broadcasting easy to adjust reliable, adjusting range is large; Strong adaptability, nonclogging multi-functional indent type precise seeder, this seeding unit has following characteristics:
1, by broadcasting quantity regulating device, the amount of broadcasting is easy to adjust, reliable.Unclamp wing nut, rotary fine adjustment handle, by thread belt mantle type fine setting push rod and the circular cone slippery fellow that is connected thereon, together rotate and move axially, the traveller that slides on the foxy surface of circular cone radially slides at nest intraocular, thereby change the nest eye volume that holds seed, reach the fine adjustment amount of broadcasting, the amount of broadcasting is tightened wing nut after regulating and determining.
2, versatility is good.Seeding unit of the present invention can be used for broadcasting clover, millet, rape, flax etc. without awns grass seed, crops and economic crops seed.Before sowing, only need, according to the agriculture requirement of Different Crop sowing, select suitable nest eye size and number, the amount of broadcasting debugging test before broadcasting, reaches after required agriculture requirement, locking wing nut, formally sowing.
3, strong adaptability.Seeding unit of the present invention can be adapted to the sowing agriculture requirement of various ground condition landforms.For saline and alkaline poor and barren land, arid terraced fields and other places, need seeding quantity large, rotate the logical handwheel of adjusting, drive power input shaft to move axially, the traveller in one or more seeding units is all slided at circular cone slippery fellow's little end surfaces, nest eye volume increases, and each seeding unit amount of broadcasting is unified to be increased; To fertile breeding field, need precision drilling, the amount of broadcasting regulates contrary.
4, the amount of broadcasting adjusting range is large.The nest eye on rotor circumference surface can be according to seed category difference, and uniform number is 1～8, by the effect of fine setting push rod, changes the degree of depth of nest eye, and the essence amount on a large scale that realizes regulates the amount of broadcasting.
5, seeds discharging box enters kind of a port and is provided with kind of a brush, plants brush and makes for flexible material, brushes away unnecessary seed, injuring-free seed; Enter the clear kind of dividing plate that kind of port is inlayed, after sowing completes, be convenient to remaining seed to remove, simple and convenient, do not stop up, easy to operate.
Compact conformation novelty of the present invention, easy and simple to handle, highly versatile, adaptability is good, and especially by broadcasting quantity regulating device, the nest eye degree of depth of rotor surface is adjustable, realized the seeding of multi-functional indent type essence amount, improve crops or grass seed seeding quality and operating efficiency, guaranteed the output of agriculture, animal husbandry, improved crops or herb machinery harvesting work condition.
