Abstract

Disclosed is a seeder, which is the same as the traditional seeder in terms of use of rotary cultivator for soil smashing and seed covering, but is completely different from the traditional seeder in terms of a sowing mechanism. A seed intake and throwing mechanism which is composed of a seeding shaft, a seeding plate, a seed throwing spoon, a lever, a spring and a contact wheel is adopted for fetching seeds from a seed box, then the seeds are thrown into a seeding tube from the seed throwing spoon by using the principle of acceleration and inertia, and the seeds are finally sent to a set location. The seeder has the advantages of accurate seed intake amount, uniform in-soil location and adjustable row spacing during seeding, and is particularly adaptable to planting crops unsuitable for drill seeding, such as rice, rapes, soybean, peanut, corn and the like.

Description

Seed dibbler

Technical field

The utility model relates to a kind of farmland sower.

Background technology

What planting seed machinery in farmland was with the most use at present is a kind of and drilling machine-south of the River 2BG-6A type rice wheat drilling machine walking tractor matching, this is that Jiangsu Province's the Seventh Five-Year Plan-emphasis is promoted one of type during the State's Eighth Five-Year Plan period, this sower is used for wheat, barley and highland barley drilling existing decades of history, and the market recoverable amount has reached the hundreds of thousands platform.But because structurally there are a lot of drawbacks in this sower, it is that the seeding wheel that adopts a circle to have some grooves is enclosed within rotation in the drum shape Seeding box, control seeding quantity by adjusting ram gap, in fact in the control of seeding quantity, be difficult to guarantee accurately unanimity, even adjust very well, how long also use not, because the vibration of tractor usually causes a section broadcast leakage, a section multicast, sowing quantity is big, is used for the wheat, barley and highland barley sowing and still can adapts to.Be not suitable for very much with this drilling machine for crop seeds such as rape, soybean, peanut, corns, the peasant still adopts program request hand-manipulated at present, and not only efficient is low for this, and labour intensity is big, and the peasant presses for a kind of multifunctional seed drill of precision point sowing.Though up to the present many scientific research institutions, agricultural machinery department, do not see a kind of desirable essence amount seed dibbler as yet all in development test on the market.

Summary of the invention:

The purpose of this utility model: the technical scheme that a kind of seed dibbler is provided, it can be regularly, quantitatively, the spacing program request, the technical solution of the utility model is to utilize existing south of the River 2BG-6A type drilling machine to improve, in rotary tillage, hack, lid kind of a part still adopts and the identical device of existing drilling machine, and getting kind, send kind, the sowing structure has adopted the brand-new device of a cover, promptly when tractor advances, the drive sprocket of adorning on the wheel shaft 1 together rotates by sprocket wheel 2 and the sprocket wheel 4 that chain drives on the intermediate propeller shaft, and sprocket wheel 4 drives sprocket wheel 5 by chain again and rotates.When clutch 6 was in bonding state, sowing axle 7, seed tray 8, bar thick stick 14, throwing kind of spoon 9 were also done at the uniform velocity rotation thereupon.When seed tray forwards certain angle to, bar thick stick 14 1 ends with bump wheel and 15 collide, make bar thick stick 14 around fulcrum 17 rotations, a seed of at this moment throwing in kind of spoon and the spoon does to quicken rotation, when forwarding bar thick stick 14 to and bumping wheel 15 when separating, because the effect of extension spring 16 makes bar thick stick 14 plant spoon 9 rapid returns together with throwing, and throws kind of the seed that spoon is interior because action of inertia, throw to sowing pipe 11, seed tray whenever revolves and turns around, and each is thrown kind of spoon and gets in mutually kind once from seed, throws kind once to the sowing pipe again.

The utility model has the advantages that seeding quantity is accurate, the line-spacing spacing in the rows is adjustable, can prevent broadcast leakage, multicast, saves seed, improves output, easy to use and reliable, has filled up the blank that China does not still have desirable seed precise sower.

Description of drawings:

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the seed dibbler structural representation.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure 1, drive sprocket, 2, driven sprocket, 3, intermediate propeller shaft, 4, output chain gear, 5, a sowing axle sprocket wheel, 6, clutch, 7, sowing axle, 8, seed tray, 9, throw kind of a spoon, 10, seed-box, 11, sowing pipe, 12, rotary tillage lid kind of a mechanism, 13, hand tractor, 14, lever, 15, bump wheel, 16, extension spring, 17, fulcrum.

Embodiment:

In Fig. 1, Fig. 2, drive sprocket 1 is housed on the hand tractor wheel shaft, wheel shaft rotates by the driven sprocket 2 on the chain drive intermediate propeller shaft 3 and rotates when tractor advances walking; The sprocket wheel 4 of the other end dress of intermediate propeller shaft 3 also rotates thereupon; Sprocket wheel 4 drives sowing axle sprocket wheel 5 by chain and rotates.On the sowing axle 4 to 6 seed trays 8 are housed, lever 14 are housed on the seed tray 8, disconnectable sowing spoon 9 (see figure 2)s are housed on each lever,

One cover clutch 6 also is housed on the sowing axle 7, when clutch is moved binding site to, seed tray 8, lever 14, throwing kind of spoon 9 are also with the 7 together uniform rotation of sowing axle, when the galianconism that forwards lever 14 to bump wheel 15 when colliding, throwing kind of spoon is around lever 14 fulcrums, 17 rotations and produce an acceleration, continuation rotating lever 14 leaves and bumps wheel 15, because the effect of extension spring 16, lever 14, throwing kind of spoon 9 rapid returns, and seed leaves and throws kind of spoon 9 and throw to sowing pipe 11 by inertia and action of gravity, finishes and gets kind and the process of sowing.When the kind period of the day from 11 p.m. to 1 a.m that will sow different cultivars, as long as change the sowing spoon 9 of different size, when changing line-spacing as long as transfer the seed tray 8 of dress varying number, as long as change the output chain gear 4 and the sowing axle sprocket wheel 5 of the different numbers of teeth when changing spacing in the rows.

Claims (3)

1, a kind of seed dibbler, comprise the rotary tillage that is connected with hand tractor, lid kind of mechanism and sowing mechanism, it is characterized in that: sowing mechanism adopts by sowing axle (7), a seed tray (8), throws kind of spoon (9), a lever (14), bumps wheel (15), extension spring (16) is formed rotary throwing kind mechanism.
