Description
Technical field
The present invention relates to grain machine apparatus field, more particularly to a kind of upper air draught Multifunctional rice mill.
Background technology
Tradition row's bran mode of horizontal rice whitening machine, row's bran mode of air draught under more employing negative pressure.The maximum of this mode
Defect is, the grain of rice by air draught power under self gravitation and negative pressure double influence, the grain of rice during indoor moveable of milling, meeting
Substantial amounts of to be accumulated in grinding house bottom, so as to cause flow resistance larger, pressure is uneven in machine, and row's bran is not smooth, and pearling is uneven,
The excessively high various synthtic price index of energy consumption.Traditional horizontal rice whitening machine mainly has following several shortcomings：
1st, the roller of Horizontal grinding roller rice mill typically integral sintered is formed using the cast-iron core of corundum and inside.From shape
On from the point of view of, mill it is indoor shake out roller surface in addition to spiral fluted depth and width have certain change from entering, profile base
This is consistent.But reality is, the granular size and grain shape of various foodstuff grains is all different, this traditional structure
The processing request of mode plurality of cereals corn difficult to realize.
2nd, brown rice can produce chaff powder and crack rice during indoor pearling of milling.Ideally, chaff powder passes through 0.9-
The sieve aperture of 1.1mm, excludes under the action of the forces of the wind whitening chamber；And crack rice and arranged by whitening chamber outlet together in company with the complete grain of rice
Remove.But reality is, diameter cracking rice less than 0.9-1.1mm can under the action of the forces of the wind, in company with chaff powder together, from lower air port
Exclude, mixing packing.Because the value cracked rice differs greatly with the value of Testa oryzae, so as to greatly waste can be caused.
3rd, the outlet of traditional horizontal rice whitening machine, more using simple pressure door discharger.Have a disadvantage in that, in effective wind
Under power effect, the chaff powder produced in pearling room, it is impossible to all excluded by sieve aperture.Always there is a small amount of chaff powder meeting companion rice together
Exclude.So as to cause the condition of rice bad；Or flow ipe causes chaff powder to stockpile, and is not easily cleaned；Or road rice machine after flowing into, give
Afterwards rice machine in road increases burden.
The content of the invention
It is an object of the invention to provide a kind of upper air draught Multifunctional rice mill, it discharges Testa oryzae using upper air draught mode,
The defect that traditional rice mill grain of rice is accumulated in bottom is prevented；Screen bran selenium segregation apparatuss are set up, secondary sieve can be carried out to cracking rice
Remove；Rear essence is set up on main shaft and grinds roller, be available for the grain that client processes as needed in process flexibly to select.
The technical scheme is that：A kind of upper air draught Multifunctional rice mill, including rice mill body and for drive grind
The motor of rice machine, described rice mill body includes charging aperture, the white rooms of Chan, main shaft and rice discharging opening, described major axis horizontal
It is arranged in pearling room, the main sand roller for husk rice is fixed with described main shaft, described rice mill bodies top is provided with
For the upper inlet scoop of bran, described whitening chamber side is provided with whitening chamber air inlet, and described whitening chamber air inlet passes through
Whitening chamber is communicated with upper inlet scoop, and described whitening chamber bottom is provided with discharging opening of cracking rice.
Further, described main shaft is fixed with rear essence roller in main sand roller side.
Further, described main shaft is the hollow shaft-like structure for being radially provided with aperture, the end of the main shaft and pearling
Room air inlet is connected.
Further, the cavity for ventilation is provided between described main sand roller and main shaft, described main sand roller is along footpath
To the through hole that communicates with cavity is provided with, described through hole is connected with upper inlet scoop.
Further, described rice discharging opening be located at rice mill body side, the entrance of the rice discharging opening with
The bottom of whitening chamber one end is connected.
Further, the side of the rice mill body is provided with screen bran selenium segregation apparatuss, described rice discharging opening
Positioned at the bottom of screen bran selenium segregation apparatuss.
Further, described rice discharge outlet is provided with outlet pressure door.
Further, the screen bran selenium segregation apparatuss are cavity structure, and it is outer that it includes that top board and top board bottom connect
Plate, inner panel and connection outside plate, the side plate of inner panel, are connected with the chaff suction tube being connected with whitening chamber on described inner panel, described
Outside plate air inlet is provided with outside plate, side plate air inlet is provided with described side plate.
Further, described screen bran selenium segregation apparatuss are internally provided with deflector.
Further, described rice mill body both sides are each provided with a whitening chamber air intake connected with main shaft two ends
Mouthful.
The invention has the beneficial effects as follows：Using upper air draught mode, the grain of rice is made in whitening chamber by strong negative-pressure wind-force
With overcoming the gravity of the grain of rice and be in suspended state, so as to prevent the defect that traditional rice mill grain of rice is accumulated in bottom, it is ensured that grind
White interior rice current density, whitening pressure are uniform, reduce rice flow resistance power, and reducing energy consumption reduces broken.Meanwhile, chaff powder and fine broken rice by
Different in quality, in machine frame inside automatic classification, lightweight chaff powder is excluded by upper inlet scoop, relatively heavy small brokens or fine broken rice,
It is affected by gravity, falls naturally.Realize that little broken and fine broken rice is collected separately, greatly reduce raw grain and waste, improve rice factory benefit.
Rice discharging opening arranges screen bran selenium segregation apparatuss, makes rice carry out secondary cleaning, reduces meter Wen, the mesh on whole net surface
's.And rear essence roller is set up on main shaft, it is available for the grain kind species that client processes as needed in process to carry out spirit
It is living to select, enable this rice mill to be widely suitable for the processing of various grain kinds.
