Description
Technical field
The invention belongs to plant equipment manufacturing technology field, relate to a kind of seed machining processes equipment, be specially a kind of centrifugal suspension seed polishing machine.
Background technology
When the current quality to vegetable seeds and packing instructions more and more higher, to the vegetable seeds (as carrot, tomato etc.) with prickle carry out except awns process be an indispensable processing link.Traditional bearder can be divided into two classes by the pattern except awns parts: a class is brush, motor driven hairbrush rotates in bucket, seed contacts with hairbrush, friction and reach the object of depilation, this kind of bearder to curry, kneading action, seed percentage of damage is low, but this bearder changes batch cumbersome, and the seed not easy-clear in hairbrush, except awns rate and productivity ratio low; Another kind of is spike-tooth or plate tooth, interior drum rotating and rotating speed is higher, and outer cylinder is fixed, act as master to hit, kneading action is that auxiliary carrying out removes awns processing, and its shortcoming is except awns rate is low, percentage of damage is high, and its reason has two: spike-tooth or the higher Beating Strength of plate tooth cause the fragmentation of seed; Outer cylinder maintains static, its bottoms material movement velocity is slow even motionless, form operation dead band, awns cannot be removed, and too little seed (most of vegetable seeds) utilizes mechanical organ to directly act on seed to realize except awns is difficult to ensure its uniformity and remove awns effect, and easily causing seed to damage, namely the seed of planting hair can remove kind of a hair by rubbing.Its key except awns is to rub intensity and uniformity.
Find by literature search, " Transactions of the Chinese Society of Agricultural Engineering " third phase in 2000 (16 volume) 60 pages, one section of Documetary Title is: " experimental study of vegetable seeds bearder ", document readme is: this device utilizes the progradation of conveying spiral, make between the seed of band kind hair, between seed and spiral and housing, even kneading action occur, kind of a hair is removed.Primary structure bearder is by motor, frame, conveying spiral, form except awns dish, pressure valve, hopper, agitator and support etc.Except awns process is after material evenly feeds, constantly stir with the rotation of helical blade, rub and rub, along with the continuous feeding of material, the extruding of storeroom increases gradually, make stirring and frictional force increasing, after reaching certain pressure, namely push pressure valve open, except namely the seed of good awns can discharge from material mouth, thus reach the object except awns.When the pressure in screw feeder after flowing out a part of seed is less than valve opening pressure, valve is just closed automatically, and the seed in screw feeder continues to be rubbed except awns, when pressure reaches opening pressure again, then flows out the seed of a part except good awns.For increasing the seed uniformity that stirs in screw feeder, rub, helical blade can stud with sticking plaster, and that can strengthen material rubs degree, material remove awns better effects if.In the form of sheets or irregularly shaped, excessive overstocks the breakage that may cause seed to some vegetable seeds; The powder that produces can not be separated automatically with seed in except the process of awns, the easy residual powder of bucket inwall, and also needs dust removal process after seed discharging; Process front remaining seed not easily to discharge.
Summary of the invention
The present invention is directed to existing seed except awns, the deficiency of polishing machine technology and defect, aim to provide a kind of centrifugal suspension seed polishing machine, utilize the principle of rubbing except awns, adopt the method for centrifugal suspension, reach the object of polishing, dedusting.
The present invention is achieved through the following technical solutions:
A kind of centrifugal suspension seed polishing machine, comprise polishing chamber, motor and blower fan, wherein polishing chamber is made up of column barrel and cone bucket, cone bucket is fixed on motor shaft, and be wind chamber between motor, wind chamber is taper, and wind chamber wall struggles against with cone and keeps the gap of 1mm, and blower fan is connected with wind chamber by the opening on the wall of wind chamber.
Drum top, polishing chamber is provided with draught hood, draught hood is furnished with top cover, in order to closed charging aperture, top cover is furnished with air-out dust removing tube near bucket wall place, drum madial wall is furnished with the barrier rib be vertically riveted on barrel wall, drum sidewall is provided with discharging opening, and uses discharge door windscreen, and discharging opening is connected with feed box.
Described air-out dust removing tube is equipped with filter screen prevents seed from leaking.
Described cone bucket is provided with perforate, by the pressure-air input polishing chamber in wind chamber.
Beneficial effect of the present invention is:
1) based on the principle of rubbing except awns, have employed the method for centrifugal suspension, greatly reduce the breakage rate of seed, polishing, dedusting synchronously complete;
2) two barrier ribs vertically placed are housed on bucket wall, and the seed of centrifugal motion and barrier rib collide, and seed is under the effect of barrier rib, and the movement locus of formation " 8 " shape, adds the chance that seed and seed rub, enhance except awns effect;
3) wind chamber wall and cone have the gap of about 1mm between struggling against, and are placed on cone bucket blower fan below, are at a high speed blown into air in the cavity formed that struggles against along gap to bucket wall with cone, and make seed suspension, alleviate the collision of seed and bucket wall, avoid seed to damage, make dust be discharged by air outlet simultaneously;
4) at the end of seed treatment, cone bucket is rotated further, and discharge door is opened, and seed throws away because of centrifugal force, and discharging is clean without remaining, and compact integral structure, efficiency is high.
