Abstract

A kind of seed dibbler, it is planted with traditional the same also lid with the rotovator hack of planter, but it is different fully with traditional sower on sowing mechanism, its adopts sowing axle, seed tray, throwing kind spoon, lever, extension spring, bump that wheel forms get kind and throw kind of a mechanism seed is taken out from seed-box, utilize the principle of acceleration and inertia that seed throwing from throw kind of spoon is entered to sow the position that pipe is delivered to setting.It is accurate that it gets kind of quantity, and it is even to deliver in the soil position, and line-spacing, the spacing in the rows of sowing are adjustable, are particularly suitable for the crop seeding that paddy rice, rape, soybean, peanut, corn etc. are not suitable for drilling.

Description

Seed dibbler

Technical field

The present invention 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 with on the method for adjusting seeding quantity all 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:

Purpose of the present invention: the technical scheme that a kind of seed dibbler is provided, it can be regularly, quantitatively, the spacing program request, technical scheme of the present invention 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, adopted the brand-new device of a cover in sowing structure and the type of seeding, promptly adopt seed tray, throw kind of a spoon, lever, bump wheel, kind of a mechanism is got in extension spring combination, it be actually with one group of manipulator from seed-box get at regular time and quantity kind and utilize the acceleration of seed and inertia is thrown it in sowing pipe so arrival by a line spacing, the acupuncture point that spacing in the rows is set.

Advantage of the present invention is that seeding quantity is accurate, and 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:

The present invention is further described below in conjunction with drawings and Examples.

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 is 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, throw kind of spoon 9 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, since the effect of extension spring 16, lever 14, throw 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

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.

2, seed dibbler according to claim 1, it is characterized in that: the sowing axle (7) of rotary throwing kind mechanism and seed tray (8) are done to rotate continuously, lever (14), throw kind of a spoon (9) and remove and follow seed tray (8) together rotates, with bump wheel (15) and also do one section acceleration rotation when contacting.

3, seed dibbler according to claim 1, it is characterized in that: on the sowing axle (7) adjustable seed tray (8) is housed, disconnectable throwing kind spoon (9) is housed on the seed tray (8), has on the seed-box (10) with throwing kind of a spoon (9) and sow pipe (11) one to one.
