The invention discloses a seed taking device which comprises a shell, a fan, a seed taking wheel and a driving device, wherein the fan is arranged on the shell; the top of the shell is provided with a seed inlet, the bottom of the shell is provided with a seed outlet, and a seed taking cavity is formed inside the shell; an arc-shaped seed throwing track is formed on one side wall surface of the seed taking chamber, the lower end of the seed throwing track is an inlet end of the seeds, the upper end of the seed throwing track is an outlet end of the seeds, and the fan blows air towards the inlet end; the seed taking wheel is arranged in the seed taking chamber and is driven to rotate along the seed throwing direction by the driving device; the seeds enter the seed taking cavity from the seed inlet, are blown by the fan to enter the seed throwing track, are thrown onto the seed taking wheel, rotate along with the seed taking wheel, are transferred and fall to the seed outlet. This kind of ware of getting adopts wind-force to blow up the seed and steadily descend on getting the kind of a wheel, has effectively avoided the direct extrusion of getting the seed production of scraping of mechanical type, has alleviateed the impact damage to the seed, has improved the survival rate of crop to also effectively improved and got kind of efficiency.

Description

Seed taking device

Technical Field

The invention belongs to the technical field of farming equipment, and particularly relates to a seed taking device.

Background

The seed taking device is a core device of the seeder, most seed taking devices of the current seeders take seeds mechanically, the seed taking mode has low probability and is easy to damage the seeds, and the survival rate of crops is influenced. In addition, some seeders adopt a negative pressure seed taking technology, but the seed taking device of the technology is not mature so far, the seed taking efficiency is low, and the application is limited greatly.

Disclosure of Invention

The purpose of the invention is as follows: in order to overcome the defects of the prior art, the invention provides a seed taking device which is not easy to damage seeds.

The technical scheme is as follows: the seed taking device comprises a shell, a fan, a seed taking wheel and a driving device, wherein the shell is provided with a first fan; the top of the shell is provided with a seed inlet, the bottom of the shell is provided with a seed outlet, and a seed taking cavity is formed inside the shell; an arc-shaped seed throwing track is formed on one side wall surface of the seed taking chamber, the lower end of the seed throwing track is an inlet end of the seeds, the upper end of the seed throwing track is an outlet end of the seeds, and the fan blows air towards the inlet end; the seed taking wheel is arranged in the seed taking chamber and is driven to rotate along the seed throwing direction by the driving device; the seeds enter the seed taking cavity from the seed inlet, are blown by the fan to enter the seed throwing track, are thrown onto the seed taking wheel, rotate along with the seed taking wheel, are transferred and fall to the seed outlet.

Specifically, a plurality of seed storage grooves are circumferentially distributed on the seed taking wheel, and when the seed storage grooves rotate to the throwing path of the seeds, notches of the seed storage grooves are over against the throwing path.

And when the seed storage groove rotates to the position above the seed outlet, the notch of the seed storage groove is opposite to the seed outlet. So as to fall to the seed outlet along with gravity.

Has the advantages that: compared with the prior art, the seed taking device blows seeds by adopting wind power, and performs parabolic motion along the seed throwing track, so that the seeds stably land on the seed taking wheel, the extrusion of the seeds caused by mechanical direct scraping is effectively avoided, the impact damage to the seeds is reduced, the survival rate of crops is improved, and the seed taking efficiency is also effectively improved.

FIG. 3 is a front view of the seed-taking wheel, showing only one seed storage tank.

Detailed Description

As shown in fig. 1-3, the seed taking device comprises a shell 1, a fan 2, a seed taking wheel 3, a driving device 4 and a seed brush 5. The top of the shell 1 is provided with a seed inlet 11, the bottom is provided with a seed outlet 12, and the two are communicated with the internal seed taking cavity 10.

One side wall surface of the seed taking chamber 10 forms an arc-shaped seed throwing track, the lower end of the seed throwing track is an inlet end of the seeds, and the upper end of the seed throwing track is an outlet end of the seeds.

The fan 2 is fixedly arranged at the lower part of the shell 1, and an air outlet 21 of the fan is arranged in the seed taking chamber 10 and blows air towards the inlet end of the seed throwing track. When seeds enter from the seed inlet 11, the seeds fall to the vicinity of the entry end of the seed throwing track and are immediately blown into the seed throwing track by wind.

The seed extracting wheel 3 is also arranged in the seed extracting chamber 10 and near the throwing end of the seed throwing track. The driving wheel which is arranged outside the shell 1 is connected through a wheel shaft penetrating through the shell 1, the driving wheel can adopt a belt wheel or a chain wheel, and is driven by a motor to jointly form a driving device 4 of the seed taking wheel 3 so as to drive the seed taking wheel 3 to rotate along the seed throwing direction.

The seed taking wheel 3 is circumferentially provided with a plurality of seed storage grooves 31, and when the seed storage grooves 31 rotate to the throwing path of the seeds, the notches of the seed storage grooves 31 are opposite to the throwing path. The seeds thrown from the throwing track can smoothly fall into the seed storage tank 31, and the excess seeds are brushed away by the seed brush 5 disposed above the seed taking wheel 3 while rotating. The seed follows the rotation of seed taking wheel 3 and continues the transfer, and when this kind of groove 31 of storing rotates to seed outlet 12 top, the notch of storing kind of groove 31 faces seed outlet 12 for the seed can drop to seed outlet 12 along with gravity, accomplishes the process of getting kind.
