The utility model has accurate seed taking rate, low seeding cavity rate, simple structure and easy usage.

Description

The dibbler seed taking device

Technical field:

The utility model relates to a kind of agricultural machinery, the seed taking device that particularly a kind of dibbler is used.

Background technology:

At present, the seed taking device that dibbler is used, comprise and get kind of a shell, the long-neck seed-taking channel, seed-feeding channel, seed inlet, seed bank and go out kind of a mouth, this device is installed in the dibbler assembly cylinder, rotation along with the assembly cylinder, seed taking device enters in the assembly cylinder and ladles out the first kind of getting of pocket realization by getting kind of a shell behind the seed zone, seed unnecessary seed of overanxious major part in the time of the slippage of long-neck seed-taking channel then, seed continues overanxious indivedual unnecessary seeds in the time of the seed-feeding channel slippage, more several seeds are realized sending planting by seed inlet and are arrived seed bank, last assembly cylinder rotates to certain position, seed is realized sending kind to going out kind of a mouth from seed bank under action of gravity, enters dibbler sowing road and sowing duckbilled then.This device get in kind of the process by seed from get kind of shell successively slippage realize the Precision Seeding kind to long-neck seed-taking channel, the overanxious unnecessary seed of seed-feeding channel.Because seed size difference in the dibbler assembly cylinder, different, the direction during seed movement is changeable, and the seed that enters again and automatically when getting kind of shell is crowded mutually, this seed taking device is difficult to several seeds are accurately got into seed bank, so seed taking device is got kind of a low precision, go into the seed number per instability, reach the 4-5 grain at most, the hole promptly appears at least, cause and emerge irregular or be short of seedling, so both wasted seed, also increased labour intensity.

The utility model content:

The purpose of this utility model be to provide a kind of simple in structure, get kind accurately, the low dibbler seed taking device of sowing hole rate.

For achieving the above object, the technical solution adopted in the utility model is: this apparatus main body is a fixed block, this fixed block is provided with the hole, be provided with mobilizable arm pivot post in this hole, described arm pivot post is provided with column and gets kind of a cup, gets kind of a cup outer wall and is provided with several storage kind of caves, and described arm pivot post one end is provided with torsion spring, the other end is provided with handle, and this handle is corresponding with the cam that has the tooth of stumbling.

As a kind of improvement project of the utility model be: the tooth of stumbling of described cam is made up of shaggy tooth and sawtooth.

As another improvement project of the utility model be: establish the culture transferring device that has the culture transferring blob of viscose by described cam center axle.

During use, cam of the present utility model is fixed on the dibbler assembly drum central axis, be with the cam of the tooth of stumbling to be positioned at assembly cylinder the latter half seed zone place, fixed block of the present utility model is installed on the dibbler assembly cylinder inner ring, the hole of fixed block is corresponding with dibbler sowing road and sowing duckbilled, what sowing duckbilleds dibbler has, and what the utility model seed taking devices just are installed accordingly.During sowing, the dibbler assembly cylinder rotates, seed taking device also rotates thereupon, cam maintains static, when seed taking device goes to assembly cylinder the latter half seed zone, the handle of this device is dialled the tooth of stumbling that hits on the cam, handle is stressed to be depressed, and gets the seed at the aligning seed zone place, storage kind cave on kind of the cup, because seed moves with the rotation of assembly cylinder, seed enters storage kind of cave, realize just getting kind, get in kind of the process handle and constantly dial the tooth of stumbling that hits cam, get kind of a cup and constantly shake and vibrate, the storage kind cave that seed is promptly and accurately entered get on kind of the cup, handle progressively leaves cam, and return under the torsion spring effect is got storage kind cave band on kind of the cup and seed and turn to assembly cylinder sowing road, seed enters dibbler sowing road and sowing duckbilled under action of gravity, wait to sow; According to actual needs seeding quantity size, get and establish respective amount storage kind of a cave on kind of the cup, because a seed is only adorned in storage kind of a cave, so the utility model is got kind accurately, it is low, simple in structure, easy to use to sow hole rate.Dibbler whenever circles and is installed in each work of the interior seed taking device of assembly cylinder once, cycle operation successively.The tooth of stumbling of cam of the present utility model is made up of shaggy tooth and sawtooth, handle is at first dialled the shaggy tooth that hits cam, getting kind of a cup, to wave the width of cloth bigger, the seed that is beneficial to seed zone enters storage kind of cave, handle is dialled the sawtooth that hits cam then, at this moment get kind of a cup and slightly shake and vibrate, be beneficial to the seed that just enters storage kind of cave and in time go into the position, avoid storage kind of a cave hole to occur.The utility model is also established the culture transferring device by the cam center axle, the culture transferring device is the same with cam, do not rotate with the dibbler assembly cylinder, the culture transferring blob of viscose of this culture transferring device is aimed at kind of the cup of getting of the present utility model, along with the rotation of assembly cylinder, the culture transferring blob of viscose can be by force be removed the seed that stops up storage kind of cave, and it is kind more accurate to get.
