Description

Centrifugal floated seed polisher

Technical field

What the present invention relates to is a kind of crop seeds polishing, bearder tool, specifically is a kind of centrifugal floated seed polisher.Belong to agricultural mechanical field.

Background technology

To the quality of vegetable seeds and packing instructions under the more and more higher situation, it is an indispensable processing link that the vegetable seeds (as carrot, tomato etc.) that has prickle is removed the awns processing at present.Find by literature search, people such as minister's flag deliver " Experiment and Research on Awner of Vegetable Seed " literary composition on 60 pages of " Transactions of the Chinese Society of Agricultural Engineering " third phases in 2000 (16 volume), document readme is: this device utilizes the progradation of defeated material spiral, make between the seed of band kind of hair, even kneading action takes place between seed and spiral and the housing, will plant and mao remove.The primary structure bearder by motor, frame, defeated material spiral, remove awns dish, pressure valve, hopper, agitator and support etc. and form.Remove the awns process after material evenly feeds, constantly stir with the rotation of helical blade, rub and rub, continuous feeding along with material, the extruding of storeroom increases gradually, make stir and frictional force increasing, after reaching certain pressure, promptly push the pressure valve open, the seed that has removed good awns promptly can mouthful be discharged from material, thereby reaches the purpose except that awns.Pressure after flowing out a part of seed in the screw feeder is less than the valve opening pressure, and valve is just closed automatically, and the seed in the screw feeder continues to be rubbed except that awns, when pressure reaches opening pressure once more, flows out the seed that a part is removed good awns again.For increase the uniformity that seed stirs, rubs in screw feeder, on helical blade, can stud with sticking plaster, can strengthen the degree of rubbing of material, material except that the awns better effects if.But some vegetable seeds in the form of sheets or irregularly shaped, excessive overstocks the breakage that may cause seed; The powder that produces in removing the process of awns can not separate automatically with seed, the easy residual powder of bucket inwall, and also need dust removal process after the seed discharging; Remaining seed is difficult for discharging before finishing dealing with.

Summary of the invention

The present invention is directed to deficiency and the defective of existing seed except that awns, polishing machine technology, a kind of centrifugal floated seed polisher is provided, make it based on the principle of rubbing except that awns, adopted the method for centrifugal suspension, greatly reduce the breakage rate of seed, polishing, dedusting are finished synchronously, and discharging does not totally have remnants, compact integral structure, the efficient height.

The present invention is achieved by the following technical solutions, the present invention includes: at the bottom of draught hood, top cover, discharge door, discharging opening, charging aperture, barrier rib, awl bucket, connector, motor, base, air-out dedusting mouth, bucket wall, the cone tank, blower fan, frame.Its annexation is: the framework of base, frame, bucket wall riveted joint cost device, riveted joint forms the cavity A of seed treatment at the bottom of draught hood, top cover, bucket wall, the cone tank, discharge door is contained on barrel wall, be positioned at top, awl Dou Ding plane, motor and blower fan are fixed on the base, awl bucket is fixed on the motor shaft, and between the bucket wall space is arranged, and with form wind chamber B at the bottom of the cone tank.Blower fan by cone tank at the bottom of on the hole of opening, aweather be blown into pressure-air in the B of chamber, pressure-air blows to cavity A through awl bucket and space between the bucket wall, makes the seed suspension.Barrier rib vertically is riveted on barrel wall, and air-out dedusting mouth is contained on the top cover, filter screen is housed on the air-out dedusting mouth prevents that seed from leaking.Charging aperture is arranged on the top cover below and communicates with cavity A, opens top cover during charging, pours seed from charging aperture in cavity A.Discharging opening is arranged on discharge door one side, and seed rotated in bucket when discharge door was closed, and when discharge door was opened, discharging opening communicated with discharge door, and seed gets rid of under the action of the centrifugal into discharging opening.

The present invention vertically rotatablely moves the seed of conventional polisher to become and horizontally rotates motion, and seed is under the drive of horizontal taper bucket, and because of centrifugal force is thrown on barrel wall, with the bucket wall friction, seed and seed friction simultaneously reaches the effect except that awns; Two vertical barrier ribs of placing are housed on the bucket wall, the seed of centrifugal motion and barrier rib collision, seed forms the movement locus of " 8 " shape under the effect of barrier rib, increased the chance of seed and seed friction, has strengthened to remove the awns effect; Boring between bucket and bucket wall has the slit, is arranged on the following blower fan of awl bucket, and high speed is blown into air in the cavity that bucket wall and awl bucket are formed along the slit, and seed is suspended, alleviate the collision of seed and bucket wall, avoid the seed damage, dust is discharged by air-out dedusting mouth; When seed treatment finished, the awl bucket was rotated further, and discharge door is opened, and seed throws away because of centrifugal force, thereby realized not having remaining discharging.

The present invention has substantive distinguishing features and marked improvement.The present invention has compared with prior art increased parts such as barrier rib, awl bucket, air-out dedusting mouth, blower fan, has saved defeated material spiral, pressure valve, has removed parts such as awns dish, agitator, and is simple in structure, compact; Changed the seed movement mode, used the method for centrifugal suspension, owing to do not have the strike and the extruding of hard thing, the simple collision friction that relies on the quality of seed and get rid of the generation of dish centrifugal action, damage to seed reaches minimum, and realization removes awns and dedusting is finished synchronously, and the complete nothing of discharging is remaining; Whole system realizes the efficient awns that removes under the control of single-chip microcomputer, be specially adapted to the processing of multiple batches of variety classes vegetable seeds.
