Abstract

The invention relates to a seed dibbler. Like a traditional dibbler, the seed dibbler adopts a rotary cultivator to pulverize soil and cover seeds, but is quite different from a traditional seeder about a seeding mechanism, and the seeding mechanism comprises a seeding shaft, a seeding tray, a seed-casting spoon, a lever, a tension spring and a touch wheel. The seeds are taken out form a seed box by a seed-fetching and casting mechanism and cast from the seed-casting spoon into a seeding pipe by utilizing the principles of acceleration and inertia so as to be sent to set positions. The seed dibbler can fetch precise number of seeds, uniformly cast the seeds in the soil, can adjust row distances and planting distances and is particularly suitable for seeding crops unsuitable for drill seeding, such as paddy, rape, soybeans, peanuts, corn, and the like.

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 one of Jiangsu Province's the Seventh Five-Year Plan one emphasis popularization during the State's Eighth Five-Year Plan period type; It is historical existing decades that this sower is used for the wheat, barley and highland barley drilling, 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, controls seeding quantity by the adjustment ram gap; In fact in the control of seeding quantity, be difficult to guarantee accurately consistently,, how long also use not even adjust very well; 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.Very unsuitable 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 object of the 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; Still adopt and the identical device of existing drilling machine in rotary tillage, hack, lid kind part; And getting kind, giving kind, adopting the brand-new device of a cover in sowing structure and the type of seeding; Promptly adopt seed tray, throw kind of spoon, a lever, bump wheel, the extension spring combination gets kind of a mechanism, it is actually with one group of manipulator and gets at regular time and quantity kind and the acceleration that utilizes seed and inertia are thrown sowing with it and managed the interior and then arrival acupuncture point by a line spacing, spacing in the rows setting from seed-box.

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, practices thrift 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 accompanying drawing and embodiment the present invention 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 through chain and drives driven sprocket 2 rotations on the intermediate propeller shaft 3 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 through 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, and when clutch was moved binding site to, seed tray 8, lever 14, throwing kind of spoon 9 were also with the 7 together uniform rotation of sowing axle; When the galianconism that forwards lever 14 to bump wheel 15 when colliding, throw kind of spoon around lever 14 fulcrums, 17 rotations and produce an acceleration, continue rotating lever 14 and leave and bump wheel 15; Because 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 lean on inertia and action of gravity to throw to sowing pipe 11, accomplishes the process of planting and sowing of getting.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 a sowing axle sprocket wheel 5 of the different numbers of teeth when changing spacing in the rows.

Claims

1. seed dibbler; Comprise rotary tillage lid kind of the mechanism (12) and the sowing mechanism that are connected with hand tractor (13); Said sowing mechanism comprises chain gear transmission parts, rotary throwing kind mechanism and clutch three parts, it is characterized in that: rotary throwing kind mechanism by seed-box (10), sowing axle (7), a seed tray (8), throw kind of spoon (9), lever (14), an extension spring (16), bump wheel (15) and manage (11) and form with sowing; On sowing axle (7), 4 to 6 adjustable seed trays (8) are housed, lever (14) is housed on the seed tray (8), disconnectable throwing kind spoon (9) is housed on the lever (14), kind of a spoon (9) is housed and throws on seed-box (10) sow pipe (11) one to one; Sowing axle (7) and seed tray (8) rotate continuously; Lever (14) and throw kind of spoon (9) except that following seed tray (8) together rotates; When lever (14) with bump wheel (15) and also do one section when contacting and quicken to rotate; When lever (14) when bumping wheel (15) and break away under extension spring (16) elastic force effect rapid return, seed then leaves to be thrown kind of a spoon (9) and throws to sowing and manage (11).
