Description
Technical field
The utility model relates to a kind of air-sucking type cylinder seeder, belongs to agricultural mechanical field.
Background technology
Pseudo-ginseng is the distinctive rare medicinal herbs in Yunnan Province, is described as " jewel " that Crop Diseases in Yunnan is bright.Due to the medicinal efficacy of pseudo-ginseng uniqueness, cultivated area and gross yield cumulative year after year.But, flourish along with pseudo-ginseng industry, pseudo-ginseng production mechanization technology very backwardness.Through investigating on the spot, only have part to plough and use machinery wholely, other production process all adopts traditional manual operations, the large production efficiency of labour intensity and operation quality low, cannot standardized work be realized, be unfavorable for the production of high-quality pseudo-ginseng, seriously constrain the development of pseudo-ginseng industrialization.Realize the mechanization of farm work and greatly can improve farm labor efficiency, reduce labor intensity, reduce production cost, improve quality of agricultural product and competitive ability.Therefore for making pseudo-ginseng industry develop rapidly and healthily, carrying forward vigorously pseudo-ginseng production mechanization is inexorable trend.
The cultivated area of pseudo-ginseng in 2013 has reached more than 300,000 mus, and pseudo-ginseng seeding method mainly artificial dibbling, seeding quantity is up to 200,000/mu, and the amount of labour is large, and recruitment cost is high, is therefore badly in need of development pseudo-ginseng precision planter and replaces artificial seeding.Seeding unit is the core component of precision planter.
Existing mechanical planting technology is mainly divided into mechanical type and pneumatic type sowing by seeding method; The requirement of mechanical type to seed is higher, comparatively large to seed damage, easily causes the probability of replays, broadcast leakage and wound kind, is not suitable for this not too regular seed crop of pseudo-ginseng.Pneumatic type sowing is main based on air-sucking type, at present pneumatic drum type sower on the market, is mainly divided into single cylinder and twin-roll.Twin-roll has better adsorption effect, but sucker can be caused to block simultaneously, the deficiency of seed difficult drop-off, and because the frictional force in cylinder wall is large, adsorptive pressure too disperses, and affects the airflow homogeneity in negative pressure cavity, and complex structure.Single cylinder can be divided into positive/negative-pressure and single negative pressure mode by negative pressure mode., due to the effect in positive/negative-pressure chamber, can there is poor sealing in positive/negative-pressure cylinder, easily produce the situation of air-flow confusion, and structure is also comparatively complicated simultaneously.Single cylinder negative pressure cylinder has the advantages such as structure is simple, but owing to working long hours, can cause the situation that sealing property declines.Herein for this present situation, adopt linear bearing spring assembly, to the situation that the sealing property that may cause due to long-term work declines, improve, guarantee that seeding unit has good service behaviour all the time.The requirement of pseudo-ginseng Precision Seeding can not be met for existing mechanical planting technology, a kind of single cylinder aspiration suction type pseudo-ginseng precision seeder of special development simultaneously.
Summary of the invention
The utility model provides a kind of air-sucking type cylinder seeder, to solve the problem that artificial simple grain program request labour intensity is large, sowing efficiency is low, cost of labor is high, operation quality is low.According to the characteristic of Panax notoginseng seeds, pointed development is applicable to the accurate air-sucking type cylinder seeder of pseudo-ginseng, this mechanical energy meet pseudo-ginseng precision drilling requirement, ensure operation quality, improve operating efficiency, reduce labour intensity and operating cost, the advanced agronomic technique of promotion promotes.
The utility model air-sucking type cylinder seeder comprises blower fan 1, dividing plate 2, hollow shaft 3, cylinder 4, sprocket wheel 10, linear bearing spring assembly 13, cylinder 4 two ends are separately installed with end cap 6, hollow shaft 3 is arranged on end cap 6 center at cylinder 4 two ends, blower fan 1 be arranged on hollow shaft 3 one end and with its connection, hollow shaft 3 has hole II 12, the end cap of cylinder 4 one end is provided with sprocket wheel 10, sprocket wheel 10 is connected with hollow shaft 3 by bearing, dividing plate 2 is arranged on cylinder bottom, and be close to inner wall of rotary drum, cylinder 4 has hole I 7, linear bearing spring assembly 13 is arranged on dividing plate 2, linear bearing spring assembly 13 other end is fixing on center shaft.
Described hole I 7 diameter is 3.0-4.0mm.
Described linear bearing spring assembly 13 comprises linear bearing and spring, and spring is contained on the slide bar of linear bearing.
Described end cap and hollow shaft junction arrange sealing ring, and end cap and cylinder junction arrange sealing ring.
Drums inside is formed between a seal area, and cylinder 4 inside is divided into two regions by dividing plate 2, and because hole in hollow shaft II communicates with drum cavity, hollow shaft is connected with blower fan, and blower fan air-breathing extracts the gas in cylinder, forms negative pressure, i.e. negative pressure region at drums inside; By dividing plate area of isolation in cylinder, it is atmospheric area.
Operation principle of the present utility model is: sprocket wheel 10 rotating band moved end lid 6 rotates with cylinder, blower fan 1 extracts the air in cylinder chamber, negative pressure is formed in cylinder chamber, dividing plate 2 is pressed on cylinder wall by linear bearing spring assembly 13, and dividing plate is fixed in hollow shaft 3 and does not rotate, this compression region is atmospheric area, the seed 5 of planting in case 16 is attracted on the hole I 7 of cylinder under suction function, rotate with cylinder, when seed 5 forwards atmospheric area to cylinder, due to seed self gravitation and centrifugal action, seed comes off from cylinder wall, realizes precise sowing.
The beneficial effects of the utility model are:
1, this machine adopts linear bearing spring assembly, and dividing plate and cylinder wall precision being fitted, is rubber bottom dividing plate, namely be flexible contact with cylinder contact, spring has compensate function to it, can not produce space, cause the possibility that sealing property reduces because of rubber wearing and tearing.
2, this machine adopts single cylinder, and have structure simple, seed easily comes off, and does not produce the advantages such as blocking sucker.
3, this Machinery Design mechanism is simple, and be easy to assembly manufacturing, use cost is low, easy to operate, and to seed not damaged, seed viability is high.
