Abstract
Corn thresher of assembly cylinder cleaning sieve, including the frame, thresher, fan, cleaning sieve, row's core ware, engine and power transmission mechanism, kernel of corn cleaning sieve wherein are surrounding maize thresher's drum sieve, and fan wherein is the draught fan, and the induced duct of connecting the draught fan air intake stretches into the top of the downside sifter of sieve section of thick bamboo exit end, and the induced duct has the axial bar gettering mouth of following towards the downside of sifter. The utility model discloses an actively the effect is: forming maize granulosa rolling on the sifter, promoting the kernel of corn to sweep along to clastic, reduced the piece suspension volume above the maize granulosa, a small amount of suspended solid is siphoned away by the draught fan again, has increased substantially the edulcoration performance of thresher, the complete machine operate steadily, vibrate little, the noise low. Long service life has simplified the drive mechanism of cleaning sieve, can turn some component size down, reduces and makes and use cost.
Description
Technical field
This utility model belongs to agricultural machinery and in particular to grain separator.
Background technology
Existing maize sheller includes frame, rack-mounted corn thresher, blower fan(Air blast), niblet clear
Choosing sieve, row's core device of linking corn thresher, engine and power drive mechanism.
In the above-mentioned maize sheller continued to use for many years, niblet sorting screen detached with chip is all mounted in thresher and goes out
The plansifter face of mouthful lower section, the manner of execution of screening be the upper frequency on sieve in-plane wave formed vibration.Make
With the maize sheller of this kind of sorting screen, there is following obvious shortcoming.
1st, clean thorough, above Semen Maydiss granulosa on compass screen surface, have chip to float, not bottomed all the time it is impossible to be screened out, finally
The niblet impurity content obtaining is higher.
2nd, sorting screen consumption in operation power of reciprocating vibration is big, and reciprocally swinging is turned back to consume energy and overcome inertia force, reactive loss
Many.
3rd, sieve nest is not easy motion, thus produces larger noise.Sieve nest and adnexa are subject to the alternation of large change amplitude
Power, rapid wear.
4th, whole machine is led to run unstable, the service life of impact part.The scantling increasing for this increased again
The consumption of equipment raw material, increases manufacturing cost.
Utility model content
The purpose of this utility model is to provide a kind of maize sheller of assembling cylinder sorting screen, for corn threshing, gram
Take existing thresing machine above shortcomings.
Maize sheller of the present utility model includes frame, and rack-mounted corn thresher, blower fan, niblet are clear
Select sieve, row's core device of linking corn thresher, engine and power drive mechanism, improvements introduced is:Niblet therein is clear
Choosing sieve is the rotary screen radially around corn thresher and row's core device, and the screen drum outer peripheral face of rotary screen fixes at least two rolling rings,
In frame, screen drum support roller, fixed gear gear ring or sprocket ring on screen drum are installed in corresponding rolling ring position, and gear ring engages engine
The gear driving or chain;Blower fan therein is air-introduced machine, and the induced duct connecting fan inlet stretches into the screen drum port of export
The top of downside compass screen surface, induced duct has bar shaped gettering mouth vertically towards the downside of compass screen surface.
For promoting niblet to flow to the niblet in screen drum outlet and stirring screen drum, screen drum inner peripheral surface there is flight to lead
Stream plate.
Be using gravity promote niblet flow to screen drum outlet, the niblet port of export of rotary screen screen drum with diameter greater than another
One end.
Good effect of the present utility model is:Rotary screen can form rolling on compass screen surface for the Semen Maydiss granulosa, promotes niblet
The chip suspension amount swept along sinking, decrease above Semen Maydiss granulosa to chip, a small amount of float is siphoned away by air-introduced machine, significantly again
Degree improves the remove impurity performance of thresing machine, and degree of cleaning is high.Compare with existing thresing machine, in niblet, the chip amount of mixing reduces by one
More than half.Sorting screen and whole machine operate steadily, vibrates that little, noise is low, reduce member stress peak value.Long service life, simplifies
The drive mechanism of sorting screen, can turn some part dimensions down, reduce and manufacture and use cost.
Brief description
Fig. 1 is this utility model structural representation.
Specific embodiment
Refering to Fig. 1, including frame, rack-mounted corn thresher 1, blower fan 2, niblet sorting screen 3, linking are beautiful
Rice row's core device 4 of thresher, engine and power drive mechanism 5, improvements introduced is:Niblet sorting screen 3 therein is bag
Enclose the rotary screen of corn thresher, flight deflector is had on screen drum inner peripheral surface, the screen drum outer peripheral face of rotary screen 3 fixes two
Individual rolling ring 6 and 7, in frame, two groups of screen drum support rollers 8 and 9 that two is a group are installed in corresponding rolling ring position, and each rolling ring uses one
Group support roller supports, fixed chain wheels gear ring 10 on screen drum, and gear ring 9 engages the chain that engine drives;Blower fan 2 therein is air inducing
Machine, the induced duct 11 connecting fan inlet stretches into screen drum from the downside of rotary screen 3 port of export, and induced duct 11 is towards compass screen surface
There is bar shaped gettering mouth vertically downside.
Claims (3)
