The processing method of a kind of wild rice stem cleaning peeling integration apparatus described above, it is characterised in that comprise the following steps:
1) wild rice stem first wash
A, first by feed hopper by after harvesting wild rice stem send into the first purge chamber in, wild rice stem is in self gravitation effect lower edge
The first filter and fall into the first purge chamber, open the first water storage box above the first purge chamber, the water of storage is passed through into water delivery
Pipe is rinsed through the first shower nozzle to wild rice stem, loads wild rice stem while rinsing, until the wild rice stem in the first purge chamber accounts for first
The 1/3 of purge chamber;
B and then wild rice stem is drained 3~5 minutes, sludge and water that flushing is got off is fallen into by the first filter together
In one collecting-tank;
C, gate between the first purge chamber and peeling chamber is then opened, wild rice stem is sequentially entered in order in peeling chamber;
2) wild rice stem is removed the peel
A, by the wild rice stem of gate the first conveying is horizontally entered into order in the presence of wild rice stem auxiliary positioning mechanism first
Take, prevent wild rice stem from accumulating and influence the efficiency of peeling, guide wheel carries out independent righting to the wild rice stem of each entrance peeling chamber, makes hay
White position is vertical with the moving direction holding of first conveyer belt, is easy to remove the peel the clamping of mechanism;
B, when wild rice stem in the presence of the first servomotor with first conveyer belt be moved to peeling mechanism lower section when, go
Drive gear in skin mechanism is rotated forward, and drives vertical rod to move down, until jig arm close to wild rice stem, makes wild rice stem be located at two jig arm
Between clamping it is interval in, then by the 3rd servomotor by two jig arm movements close to each other, realize the clamping to wild rice stem, folder
Tight degree reaches that wild rice stem does not drop, and then drives vertical rod to move up by drive gear reversion, makes wild rice stem close to peeling
Blade;
C, then in the presence of cylinder, make sliding block drive peeling mechanism to be moved to first conveyer belt and second along guide rail
Clearance position between conveyer belt, now at the uniform velocity rotates peeling blade, starts the 4th servomotor, makes peeling blade second
Moved in the presence of boosting block along threaded rod and guide rod, peeling processing is carried out to wild rice stem after wild rice stem;
The 4th servomotor is inverted after d, peeling, makes peeling blade away from wild rice stem, while starting cylinder, passes through sliding block band
Dynamic peeling mechanism is moved to the top of the second conveyer belt, and vertical rod is moved down through drive gear, until jig arm bottom and second
5cm is smaller than between conveyer belt, jig arm is then unclamped by the 3rd servomotor, wild rice stem is fallen to the second conveyer belt
On;
3) wild rice stem secondary cleaning
After peeling terminates, wild rice stem, as the second conveyer belt is moved together, is then being weighed in the presence of the second servomotor
Fallen under power effect in the second purge chamber, the water of storage is passed through the second shower nozzle pair by the second cistern on second purge chamber's top surface
Wild rice stem is rinsed, and water droplet is directly converged in the second collecting-tank, and exported by drainpipe, and the weight of wild rice stem reaches and pushed open
When baffle plate gravity, direct wild rice stem directly enters in discharge chamber from the second purge chamber;
4) wild rice stem output vanning
Wild rice stem is exported by the delivery board in discharge chamber, and is loaded in corresponding storage bin;
5) effluent cycle is handled
Sewage in first collecting-tank is entered in sewage purifier by check valve, and realization is dirty in the presence of screen pack
Water is separated, and the water after filtering enters through the first conduit and the second conduit respectively in the presence of the first suction pump and the second suction pump
In first water storage box and the second water storage box, realize that water resource is recycled, the sludge after retention is discharged by cover plate;
6) equipment clean and maintenance
After wild rice stem cleaning peeling integration apparatus processes a collection of wild rice stem, with clear water to the first purge chamber, the second purge chamber
Cleaned with peeling chamber, and the cladding cleared up in peeling chamber, it is unified to recycle, the drive disk assembly in equipment is added and lubricated

The present invention is by adopting the above-described technical solution, have the advantages that:
1st, by the design of the first purge chamber, first wash can be carried out to wild rice stem, the sludge on wild rice stem surface is removed, prevented
Only sludge remains in wild rice stem surface and influences the decortication effect of wild rice stem;
2nd, wild rice stem auxiliary positioning mechanism can be such that the wild rice stem after cleaning enters in order in first conveyer belt, keep wild rice stem
Same direction, is easy to peeling mechanism quickly to capture wild rice stem, the efficiency of wild rice stem peeling is improved, while reducing to wild rice stem epidermis
Damage, extend wild rice stem holding time;
3rd, the second purge chamber can be cleaned to the wild rice stem after peeling, prevent the chip of wild rice stem skin from remaining in wild rice stem table
Face, influences the resting period of wild rice stem;
4th, the sewage that the first collecting-tank is collected can be directly entered in sludge purifying box, and can be again after filter screen filtration
Flow back on the first wiper mechanism and the second wiper mechanism, realize recycling for water resource, reduce the waste of water resource;
5th, process steps of the invention are simple, not only increase the removal speed of wild rice stem surface sludge, and make hay
The white damage reduced during peeling to epidermis, extends the holding time of wild rice stem, realizes automation cleaning and removes the peel, reduction
Manually-operated labor intensity.
