Abstract
The invention relates to the field of grain recleaner equipment, in particular to a gravity impurity removing box for a grain recleaner screen. The gravity impurity removing box comprises an impurity removing box body and a centrifugal fan. The centrifugal fan is arranged at the bottom of the impurity removing box body. A screen net, a grain outlet nozzle, an impurity removing nozzle, reinforced grid plates, a baffle plate and a grain control plate are arranged in the impurity removing box body. By means of mutual cooperation of the components during production, the screen net is prevented from being blocked, the air volume distribution of all sections of a screen face tends to be reasonable, and the impurity removing and separating effect is improved; and therefore the problems that in the prior art, screen holes of a grain recleaner gravity screen are prone to being blocked, cleaning is hard, and consequently the screening effect is poor, and screening efficiency is low are solved. The gravity impurity removing box is simple in structure, convenient to operate and good in whole machine use effect, the performance of the grain cleaning equipment is improved, and the productivity and screening quality of the grain recleaner gravity screen are effectively improved.
Description
Technical field:
The present invention relates to grain selecting apparatus field, particularly a kind of proportion impurities removal case of grain selecting sieve.
Background technology:
Current grain selecting proportion sieve, most employing fish scale compass screen surface, in bottom, blower fan is installed, the wind-force of the different section of adjustment compass screen surface, light weight sundries is separated with cereal, and utilize proportion principle going mouldy seed, not plump seed is gently mixed, large small impurities is discharged from impurity outlet, improves cereal and size high density impurity and delivers to grade screening choosing from grain outlet.Prior art is due to unreasonable structure, and compass screen surface each section of air quantity adjustment is undesirable, and magazins' layout is not thorough, and the impurity of fine particle shape is trapped on compass screen surface mostly, blocking sieve aperture.Need periodic cleaning sieve aperture to ensure that equipment normally works, as irregular cleaning, equipment cannot be produced, and in order to exempt periodic cleaning, reducing maintenance time, boosting productivity and impurity-eliminating effect, thus need a kind of novel proportion impurities removal case.
Summary of the invention:
The present invention is in order to overcome above-mentioned prior art defect, the proportion impurities removal case providing a kind of grain selecting to sieve, impurities removal case inside is arranged strengthens screen, deflection plate and control grain plate, cooperatively interacted when producing by these parts, avoid the blocking of screen cloth, compass screen surface each section allocation of the amount of air is made to be tending towards reasonable, impurities removal separating effect improves, the productivity ratio of effective raising grain selecting proportion sieve and screening quality, thus the grain selecting proportion sieve sieve aperture solving prior art easily blocks, cleaning difficulty, causes screening effect poor, the problem that screening efficiency is low.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A proportion impurities removal case for grain selecting sieve, comprise impurities removal case and centrifugal blower, described centrifugal blower is arranged on bottom impurities removal case, it is characterized in that:
Described impurities removal case inside also comprises screen cloth, crop release port, impurities removal mouth, strengthen screen, deflection plate and control grain plate, it is inner that described screen cloth is arranged on impurities removal case, described crop release port and impurities removal mouth are separately positioned on the two ends of screen cloth, described deflection plate is weldingly fixed on the bottom of screen cloth by strengthening screen, described reinforcement screen and screen bottom are welded and fixed, described control grain plate is weldingly fixed on one end near crop release port, screen cloth top, by sieved through sieve cereal and foreign material, by crop release port, the cereal after screening is discharged, by impurities removal mouth, the foreign material after screening are discharged, fixing of screen cloth and impurities removal case is strengthened by strengthening screen, that strengthens between deflection plate and impurities removal case and screen cloth is fixing simultaneously, by deflection plate, the wind-force of screen bottom is decomposed, compass screen surface each section allocation of the amount of air is made to be tending towards reasonable, compass screen surface foreign material are thoroughly separated with cereal, and the impurity of fine particle shape is blown off rapidly compass screen surface, cannot be trapped on compass screen surface, thus solve fine impurities blocking sieve aperture problem, further raising impurities removal separating effect, the cereal height of compass screen surface is effectively controlled by control grain plate, and highdensity tiny foreign material are sent rapidly, sieve aperture is avoided to be blocked by tiny foreign material.
Described deflection plate is arranged on screen bottom distance impurities removal mouth 300-350mm place, be welded and fixed by multiple screen of longitudinally strengthening, described deflection plate in screen bottom to impurities removal mouth direction inclination 8-10 °, the present invention is by arranging the mode of deflection plate in screen bottom, change the adjustment air quantity method that prior art is added sieve by superposition or leaked informaton, effectively prevent the sieve pore blockade of screen cloth and the working environment of proportion impurities removal case, and compass screen surface mixture section and impurities removal section wind-engaging are rationally, tiny light impurity is easy to discharge.
Described deflection plate is arranged on screen bottom distance impurities removal mouth 300mm place, and the 8 ° of wind-force discomposing effect that tilt to impurities removal mouth direction are best.
Described control grain plate is monolithic construction, control grain plate arranges grain outlet, multiple mud hole is set below grain outlet, control grain plate of the present invention not only structure simplifies, and strengthen screen box biside plate intensity, mud hole particularly below grain outlet, not only effectively to control the cereal height of compass screen surface, and granule, highly dense foreign material degree are easy to drain into lower road classifying screen from bottom slag-drip opening, avoid sieve aperture to be blocked by tiny foreign material, thus the grain selecting proportion sieve sieve aperture solving prior art easily block, cleaning difficulty, cause screening effect poor, the problem that screening efficiency is low.
Beneficial effect of the present invention is: the proportion impurities removal case providing a kind of grain selecting to sieve, impurities removal case inside arranges reinforcement screen, deflection plate and control grain plate, cooperatively interacted when producing by these parts, avoid the blocking of screen cloth, compass screen surface each section allocation of the amount of air is made to be tending towards reasonable, impurities removal separating effect improves, thus the grain selecting proportion sieve sieve aperture solving prior art easily blocks, cleaning difficulty, cause screening effect poor, the problem that screening efficiency is low, structure of the present invention is simple, easy to operate, complete machine result of use is good, improve the performance of grain cleaning equipment, the productivity ratio of effective raising grain selecting proportion sieve and screening quality.
