Abstract

The utility model discloses a machine for removing impurities from grain, which is used for grain storage departments. A bellows is arranged below a feeding funnel of the machine, air separation is carried out first, and then screening is carried out. An inducing draught apparatus is additionally arranged in the machine so as to suck out a small amount of floating dust in screened grain. Under the condition that a blower fan is not added, the clogging problem of a screen piece is solved, and secondary air separation is carried out to the grain, so the cleaning effect of equipment is enhanced further. The utility model has lower centre of gravity for working and runs stably and reliably. The utility model can be arranged on the ground to work without foot screws. The utility model is provided with action rollers, which brings convenience for changing places.

Description

A kind of grain impurity eliminating machine
The utility model relates to the grain cleaning equipment that a kind of grain storage department uses, and particularly relates to a kind of grain impurity eliminating machine.
Existing grain impurity eliminating machine mostly is two-layer cylinder sieve formula, and its screen drum is taper, and power makes its rotation by motor by the small end that one group of reducing gear drives screen drum.Pneumatic separation device is positioned at mouthful place that puts out cereal of rotary screen below, be single air blast mode, not only assorted clearly effect is difficult to guarantee, make corresponding the increasing in operating position of rotary screen again, thereby influenced the job stability of this machine greatly, only usefully foot bolt is fixing can operate as normal, shifts to the place and brings difficulty.This machine is often gone back generation sieve sheet and is blocked up phenomenon by light-duty impurity paste when working, when particularly winter, cleaning contained the grain of frost and snow, frost and snow tended to stick to sieve and makes it on the sheet to stop up, thereby greatly reduces the effect of mixing clearly.Existing in addition two-layer cylinder sieve all adopts V belt directly to drive the rotation of screen drum small end, and hour cleaning tonnage of this kind equipment is bigger, required rotating speed is lower again, therefore when momentary overload occurring, belt tends to occur skidding, the rotating speed of rotary screen is significantly reduced, even stop, have a strong impact on the cleaning efficiency of equipment.
The purpose of this utility model provide a kind of working stability, reliably, assorted clearly effective, and the grain impurity eliminating machine that can conveniently move.
The purpose of this utility model is real like this sight, blower fan is installed in the top of frame, the air outlet of blower fan and the air inlet of bellows join, elevating hopper is connected on the top of bellows, and above conical trommel, set up dust shield, the air inlet of blower fan is linked by pipeline, dust shield and internal body.Its running part adopts one group of pin tooth transmission mechanism, promptly installs a big pin gear ring in the outer edge of the big end of interior screen drum, is driven little pin gear, sells gear ring, the rotation of head roll sieve greatly through one group of belt transmission by motor.Lower margin position in frame is provided with action roller.
The utility model is owing to be located at pneumatic separator on the top of frame, before making raw grain enter rotary screen, be about to light-duty impurity and frost and snow earlier and remove, and in equipment, set up the air inducing dust exhaust apparatus, thereby reached reduction rotary screen working depth, kept away and sieved the generation that wall is stuck with paste subsides, clogging, both realized raising job stability and the clear effect of mixing, the wearing and tearing that can become to alleviate the device interior driving member again simultaneously.Adopt the running of pin gear mechanism head roll sieve, and will mesh the big end that the position is located at screen drum, still can normally move when making equipment occur transshipping at short notice, both guaranteed the stationarity of equipment work, played the effect of reducing gear again, thereby reached the raising functional reliability, the purpose that simplifies the internal structure of an organization and reduce cost.Lower margin position in frame is provided with action roller, and the mobile convenience that provides of equipment is provided, and has reached the purpose that improves utilization rate of equipment and installations and operating efficiency.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof:
Fig. 1 is the overall structure schematic diagram of grain impurity eliminating machine.
Describe in detail according to specific constructive form and the working condition thereof that the utility model proposes below in conjunction with accompanying drawing.
This grain impurity eliminating machine mainly comprises frame 15, pneumatic separator, sorting mechanism, transmission system and running gear.Pneumatic separator is made up of the blower fan 4 that is installed in frame 15 tops, elevating hopper 2, bellows 1, dust shield 6 and unicom pipeline, the air inlet of the air outlet of blower fan 4 and bellows 1 joins, elevating hopper 2 is positioned at the top of bellows 1 and communicates with bellows 1, the air inlet of blower fan 4 communicates with impurity eliminating machine inside by pipeline, dust shield 6, and dust shield 6 is positioned at the top of rotary screen near big end; Sorting mechanism is located at the inside of impurity eliminating machine, and the rotary screen of being made up of two conical sieve tube suits constitutes, and outer screen drum 5 is enclosed within on the interior screen drum 8, and rotates synchronously with interior screen drum 8, and interior screen drum 8 communicates with the bellows 1 and the elevating hopper 2 of pneumatic separator by grain downflow tube 16.Transmission system drives little pin gear 9 rotations by the motor 7 that is installed on the frame 15 by one group of belt transmission, and the pin gear rings 10 drive rotary screens of screen drum 8 big ends rotated in little pin gear 9 drove and is fixed on.Running gear is formed by being installed in the action roller 14 on frame 15 lower margins and the guiding mechanism that rises and falls.
During this grain impurity eliminating machine work, at first actuating motor 7, drive interior screen drum 8 and drive outer screen drum 5 by one group of belt gear, little pin gear 9, pin gear ring 10 and rotate synchronously.Start blower fan 4 air inducing drums inlet box 1, will treat that raw grain feed continuously from material loading 2 clearly, raw grain is from the elevating hopper 2 laggard bellows 1 of going into that get off, and light-duty impurity wherein, frost and snow etc. are cleared, by light assorted the outlet outside the 18 discharge machines.According to grain variety, contain assorted what, moisture content height and suitably adjust air quantity regulating handle 3 and grain guard board regulating handle 17 and can reach best selection by winnowing effect.Grain after the selection by winnowing fall into grain downflow tube 16 enter in screen drum 8 begin to carry out first screen, large-scale impurity became oversize and was fallen into outside the big assorted collection bucket 11 discharge machines by the large port of interior screen drum 8 this moment.Screenings grain and fine impurities fall into outer screen drum 5 and carry out postsearch screening, and grain became oversize and flowed out by the large port of outer screen drum 5 this moment, accept to fall into grain bucket 12 after the dust shield 6 secondary selection by winnowing simultaneously and are discharged to outside the machine.The screenings fine impurities falls into outside the thin assorted collection bucket 13 discharge machines.When equipment needs the transfer tasks place, can be by the guiding mechanism that rises and falls, the action roller 14 that is installed on the lower margin is landed get final product, at equipment operation or when parking, action roller 14 rises, and the lower margin of frame 15 lands.
