Description
Technical field
The utility model relates to the sower that uses in agricultural production, and especially a kind of seeding unit of sower belongs to agricultural machinery technological field.
Background technology
The sower that in agricultural production at present, the crop strip sowing plantings such as paddy rice, wheat, rape use normally adopts the seeding Type Seed Metering Device, its seed wheel can be divided into several structural shapes such as grooved pulley type, indent type and special-shaped indent hole formula, this class seed wheel can not be applicable to broadcast the larger seed of seed size great disparity usually simultaneously, the seeding unit that for example is applicable to large seed can not be used for broadcasting small-sized seed, and vice versa.Publication number is that CN10042036C's " seeding unit " patent of invention discloses a kind of seeding unit that goes for difformity, different size seed, the weak point that exists when but this seeding unit uses has: the one, and varying in size for seed kernel needs to change different seed wheels, dismounting trouble during replacing; The 2nd, owing to being only to have changed the seed wheel that is complementary for the different seed of seed size, thereby in kind of the section of protecting of seeding unit, seed wheel and inner walls form protects kind of clearance space and can not can realize effectively protecting kind of a control to the seed that varies in size, thereby can not guarantee seeding accuracy.
The utility model content
The purpose of this utility model is: for the problem that above-mentioned prior art exists, proposes a kind ofly both to be applicable to large seed, also to be applicable to small-sized seed and seeding unit easy to operate, the sowing precision.
in order to reach above purpose, seeding unit of the present utility model comprises the housing with rotating shaft, be positioned at side by side large in housing in described rotating shaft, the seedlet seed wheel, described large, the seedlet seed wheel is kink and being fixed in rotating shaft respectively, described housing be positioned at large, it is hinged that the elasticity of seedlet seed wheel below is protected kind of tongue one end, the other end that described elasticity is protected kind of tongue is resisted against greatly, the lower end of seedlet seed wheel, the end face of described large seed seed wheel has the eccentric pin hole of settling sliding pin, the end face of described seedlet seed wheel has through hole and shifting block, described through hole and shifting block are on the identical turning radius with described eccentric pin hole.
During use, the housing of the utility model seeding unit is connected with the seeder case, and when broadcasting small-sized seed, rotating shaft directly drives seedlet seed wheel rotation seeding, and large seed seed wheel remains static.When changing over when broadcasting large seed, as long as promote sliding pin, the one end is on the movement locus of seedlet seed wheel shifting block, the seeding that just is driven to rotate of large seed seed wheel, this moment the seedlet seed wheel due to its take turns on week to fill kind of cavity volume little and can not fill kind and seeding.
This shows, the utility model can the duty that easily change seed wheel large and small according to seed.And owing to having adopted elasticity to protect kind of a tongue, the arc-shaped curved surface of its front end can be resisted against on seed wheel all the time, make the seed that is filled with seed wheel wheel Zhou Shangrong kind space be in all the time and effectively protect kind of a state of a control protecting kind of section, so the seeding precision is high.
Evidence, seeding unit of the present utility model not only can be used for paddy rice, wheat the large seed planting seed such as corn, also can be used in the sowing of the fine grain seeds such as rape, sesame, have advantages of easy to operate, seeding accuracy is high.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the structural representation of seedlet seed wheel in Fig. 1.
Embodiment
As shown in Figure 1 and Figure 2, the seeding unit of the present embodiment mainly by housing 3, seedlet seed wheel 4, plant hairbrush 5, sliding pin 6, large seed seed wheel 7, Connection Block 9, seed reception bucket 10 and elasticity clearly and protect kind of a tongue and form.Housing 3 middle part supporting revolving shafts 2, seed reception bucket 10 is extended in the bottom.Be positioned at side by side the large and small seed seed wheel 7,4 in housing 3 in rotating shaft 2, large seed seed wheel kink is in rotating shaft 2, and seedlet seed wheel 4 is fixed in rotating shaft 2.It is hinged that housing 3 and the elasticity that is positioned at large and small seed seed wheel below are protected kind of tongue one end, and the other end that elasticity is protected kind of tongue is resisted against large and small seed seed wheel 7,4 lower end.The end face of large seed seed wheel 7 has the eccentric pin hole of settling sliding pin 6, and the end face of seedlet seed wheel 4 has through hole 15 and shifting block 14.Through hole 15 and shifting block 14 are on the identical turning radius with eccentric pin hole.
In addition, the present embodiment also has following design feature:
1. large and small seed seed wheel 7,4 wheel are shaped with respectively two interlaced skate teeth on week.
2. housing 3 also connects dead axle 1, elasticity is protected kind of tongue and is comprised of inner sleeve 11, tongue body 8, extension spring 12 and adjusting screw(rod) 13, inner sleeve 11 is shaped with the U-shaped outer arm that is fixedly connected with dead axle 1, tongue body 8 is hinged with dead axle 1, the two ends of extension spring 12 articulate with the U-shaped outer arm of tongue body 8 and inner sleeve 11 respectively, adjusting screw(rod) 13 is threaded with tongue body 8 roots, and its front end is resisted against the tail end of the U-shaped outer arm of inner sleeve 11.
3. comprise also that two ends contain the Connection Block 9 of axis hole, rotating shaft 2 is supported on the open semicircle orifice of housing 3, and the axis hole at Connection Block 9 two ends is connected with rotating shaft 2 with dead axle 1 respectively.
Kind of the cavity volume that fills of the large and small seed seed wheel of seeding unit of the present utility model is the between cog of upper adjacent teeth of wheel week, so difform seed all is easy to enter, and can guarantee to keep under control in elasticity with protecting kind of tongue, accurately discharges from sowing port.When broadcasting large seed, to push sliding pin to little seed wheel one side, and when broadcasting seedlet, by the through hole on little seed wheel, sliding pin is pushed in large seed wheel, two kinds of purposes conversions are very easy.Rotating shaft and housing are installed and are adopted Open architecture, make seed wheel change and are very easy to.Therefore, the utility model seeding unit can be applicable to large and small grain planting seed, has advantages of that seeding accuracy is high, simple to operate.
