Description
Technical field
The utility model relates to a kind of band clamping seed sowing device, is specially adapted to the agricultural mechanical field of many variety seeds precise sowing.
Background technology
At present, can conventional seeding unit form equidistantly to plant uniformly grain stream and accurately control seeding quantity by it and can be divided into precision metering device and non-precision metering device both at home and abroad.Precision metering device can be divided into mechanical type and Pneumatic seeding apparatus again, and wherein Pneumatic seeding apparatus comprises vapour-pressure type, air-sucking type and three kinds of forms of air-sweeping type.Its various seeding units have respectively following characteristics:
Machinery disc type seeding unit is a kind of application seeding unit more widely, according to its disk plane of rotation position, can be divided into level, inclination and vertical three kinds of forms.Horizontal seeding unit is simple in structure, reliable operation, when running at a low speed, have good work quality; Inclined plate can reduce the height that kind of mouth, but its drive mechanism more complicated; Vertically disk can reduce and kind of an open height, and transmission is simple.But disc type seeding unit is not suitable for high speed operation, and its seeding quality can not guarantee.
Air-suction seeding unit utilizes air vacuum generation suction to carry out work.Its feature is that versatility is good, can realize high speed operation, and the shape need to seed is lower, but it has air-tightness simultaneously and requires high, complex structure, be easy to wearing and tearing, the adjustment of scraping kind of sheet is cumbersome, and blower fan and power transmission structure thereof are had relatively high expectations and it fills that kind of chamber seed group state is unreasonable can affect the shortcomings such as seed-metering performance.
Air-sweeping type seeding unit is to make the row hole wheel of conical through-hole wheel week, with air current spray nozzle, to replace seed scraping device.It is good that it fills kind of performance, be easy to adjust spacing in the rows and shape of the seed is required to the advantages such as not strict, but its cost of manufacture is higher, complicated structure.
Above proposed seeding unit has following shortcoming: during sowing, easily seed is caused the injuries such as pressure break and wearing and tearing, reduce its emergence rate; Complicated in mechanical structure, is easy to wearing and tearing; Seeding accuracy is difficult for guaranteeing, causes multiple or scarce kind of phenomenon, affects grain yield; Power is had relatively high expectations, and cost of manufacture is high.
Summary of the invention
The various deficiencies of bringing for overcoming above seeding unit, the purpose of this utility model is to provide a kind of band clamping seed sowing device, outside overcoming the deficiency of seeding unit described above, can also carry out the many kind sowings of a machine, improves sowing efficiency.
It is a kind of band clamping seed sowing device that the utility model solves the technical scheme that its technical problem adopts, and its primary structure comprises: electromotor 1, discharging tube 2, discharging tube support 3, discharging tube bracket holder 4, plant storehouse 5, plant storehouse fixed support 6, frame 7, nut 8, driven shaft 9, pin 10, clamping hole 11, lower supporting plate 12, driving shaft 13, seeding band 14, projection 15.It is characterized in that: described electromotor 1 is fixed on above frame 7 by nut, described driving shaft 13 is connected on electromotor 1 by shaft coupling, and by nut 8, being fixed in frame 7 rotates above, described driven shaft 9 is fixed in frame 7 by nut 8 and rotates above, described seeding band 14 is fixed and is rotated by driven shaft 9 and driving shaft 13 projection above, described discharging tube 2 carries out matched in clearance by discharging tube support 3 and seeding band 14, described discharging tube support 3, lower supporting plate 12 and discharging tube bracket holder 4 link together by pin, and be installed in frame 7 by nut, for convenience of installing, discharging tube bracket holder 4 can be discharging tube support 3 directions mobile installation in frame 7, described kind of storehouse 5 is arranged in frame 7 by kind of a storehouse fixed support 6.
A kind of operation principle with clamping seed sowing device of the utility model is:
Electromotor drives driving shaft to rotate to dispenser input power, thereby drives seeding band and driven shaft to rotate, and all with projection, and above seeding band, have the aperture matching with its projection, and these apertures has certain elasticity on driving shaft and driven shaft.After above driven shaft, projection is backed down the aperture above seeding band, the seed of planting in storehouse is slipped in aperture automatically, after turning to certain angle, driven shaft projection slowly exits seeding band, seeding band is automatically clamped seed to transport kind of a storehouse by its elasticity, at driving wheel place, having projection above driving wheel that seed is ejected to seeding is brought in discharging tube, projection exits after seeding band afterwards, the previous status that is punctured into seeding band aperture continues to enter the clamping work that driven shaft carries out seed, thereby realizes the precision metering device operation of seed.Discharging tube, lower supporting plate seal seeding band upper and lower respectively simultaneously, in order to avoid seed is thrown out of seeding band when dispenser rotating speed is higher.
A kind of advantage with clamping seed sowing device of the utility model is: when planting, realize the precision metering device of seed and work continuously, improving the production efficiency of planting seed; In addition, can be by regulating the rotating speed of electromotor output to carry out the adjusting of operating efficiency; Avoid the damage of seed in rigid mechanical planting process; The introducing of electromotor can alleviate working strength, reduces job costs; The resilient clamp function of seeding band can realize the even operation of different-diameter seed; Above seeding band, the spacing of clamping hole has determined plantation spacing, to meet different planting seed required precisions.
