Description

Sand roller rice mill

The utility model belongs to the Cereals Processing Machines equipment technical field, particularly is applicable to the brown rice pearling of rice processing factory, rice polishing, and the sieve that revolves that brown rice is processed into polished rice sprays the wind abrasive type rice whitening machine, and its international Patent classificating number is B02B.

Existing rice mill, as NS type rice mill (husk rice technology and equipment, Heilungkiang Science Press, nineteen eighty-two), paddy processing (Chinese finance and economics publishing house) and other miniature rice mill (CN88218581, CN89211722 and CN89215191) are though simple in structure, easy to operate, but its weak point is: the content height of cracking rice in the finished product, chaff powder content height, it is low that a machine goes out white precision, and treating capacity is little.

The purpose of this utility model be exactly design in order to overcome above-mentioned deficiency a kind of compact conformation rationally, crack rice in the finished product and the chaff powder content is low, a machine go out white precision height, treating capacity big, can be used for the sieve that revolves that multimachine gently grinds, produces clean rice and spray the wind abrasive type rice whitening machine.

The purpose of this utility model can reach by following measure: traditional husk rice iron roll is changed into adopt sand roller, the interior circle of rice-milling roller to be eccentric, cylindrical has high convex tendon, and the sand roller also has ventilation slot.It is iron roll that the essence of discharge end is ground section.The husk rice chamber changes hexagonal reel by rotation and rice milling roller is formed.Wherein rotate the hexagonal screen drum, by hexagonal screen frame (unit), six roots of sensation rice cutter and 12 dull and stereotyped compositions, and with rice milling roller low speed rotation in the same way, blower fan sprays wind to the husk rice chamber.Between uniform arrangement slanted screen hole, hole salient point is arranged on the sieve plate.The husk rice chamber is terminal for closing the smart chamber of grinding of wind.Rice output outlet is axially wholecircle outlet with one heart, and plectane pressure door and smart roller axis normal also are close to rice output outlet, and the plectane pressure door is pressurizeed by spring, by regulating the pressure of pressing spring nut controlled pressure door.

Bottom, husk rice chamber is provided with chaff crushed rices separation chamber, makes rice further remove chaff and reduce temperature, separate chaff and crushed rices.Whole rice mill is that body structure, motor and reduction gearing mechanism all are closed in the body.

Further describe the utility model below in conjunction with accompanying drawing.

Accompanying drawing 1 is the structural representation that revolves sieve spray wind abrasive type rice whitening machine.

Accompanying drawing 2 is the structural representations that revolve sieve spray wind abrasive type rice whitening machine husk rice chamber.

Among the figure: the 1-motor, 2-sprays fan blade, 3-air intake sleeve pipe, the 4-bearing cap, the 5-round nut, the 6-tightly fixed liner, the 7-bearing, window on the 8-frame, the 9-main shaft, the 10-bearing, the 11-pinch roller, the 12-frame, the 13-transverse axis, the 14-worm gear, the 15-bearing, 16-lining hold-down screw, the 17-flat belt, 18-reduction box driving wheel, the 19-end cap, the 20-lining, the 21-gear, 22-connects pin, 23-husk rice chamber loam cake, the smart iron roll that grinds of 24-, the smart chamber of grinding of 25-, the 26-material retaining hood, the 27-pressure door, 28-pressing spring nut, the 29-spring, the 30-lining ring, 31-transfers the wind valve, the removable dividing plate of 32-, the 33-suction impeller, the 34-blower housing, the 35-feed hopper, the 36-spiral propeller, 37-rice cutter, 38-husk rice chamber, the 39-screen frame (unit), the 40-rice huller screen, the 41-rice-milling roller, 42-husk rice chamber cover.

Above-mentioned accompanying drawing is embodiment of the present utility model

The bottom of frame 12 is provided with transverse axis 13, and the two ends of transverse axis 13 are installed spray fan blade 2 and suction impeller 33 respectively.Main shaft 9 has the rice-milling roller 41 by the diamond dust compression molding of off-centre and jet-air slot, the smart iron roll 24 that grinds of the end configuration of main shaft 9 for spiral propeller 36 and band convex tendon are installed on hollow shaft, the axle.

The husk rice chamber is made up of rotation hexagonal screen frame (unit) 39, rice cutter 37, rice huller screen 40, rice-milling roller 41 and husk rice chamber loam cake 23.Six roots of sensation surface is installed through heat treated cast iron rice cutter 37, with hexagonal array with securing member on screen frame (unit) 39, the sieve aperture of rice huller screen 40 is oblique, and salient point is arranged between sieve aperture.

The bottom of husk rice chamber is provided with by the chaff crushed rices separation chamber that transfers wind valve 31, removable dividing plate 32, suction impeller 33, blower housing 34 to form.

The front portion of husk rice chamber is for closing the smart husk rice of wind chamber 25, rice output outlet is by pressure door 27 controls, and at the end surface means inner screw sheath of frame, the connecting rod of pressure door stretches into inner screw sheath, again spring 29 and pressing spring nut 28 are installed in wherein, regulate the pressure of pressure door 27 by rotation pressing spring nut 28.

The top of draught fan impeller 2 is provided with an air intake sleeve pipe 3, sprays wind by main shaft to the husk rice chamber.During work, actuating motor 1, draught fan impeller 2, suction impeller 33 and main shaft 9 runnings, by reduction box driving wheel 18, the flat belt 17 of main shaft 9, drive the decelerator speed change, drive screen frame (unit) 39 and main shaft 9 low speed rotation in the same way by the output roller gear of decelerator then.Brown rice enters rice mill from hopper 35, and it is manual that the size of flow is inserted door by hopper.After treating that brown rice is full of the husk rice chamber, open blower fan air register 31, by regulating the pressing spring nut 28 of feeding gate plate and outlet pressure door 27, make it meet the requirements of output and precision.Rice and chaff crushed rices are discharged from outlet.
