The specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing, and husk rice is pulverized the unit (see figure 1) and mainly is made up of rice mill (1), belt housing (2), driving-belt (3,4), pulverizer (5), support (6), motor (7), motor pulley (8).Load onto driving-belt (3), shed driving-belt (4), connect single-phase 220 volts of power supplys, rice mill work, otherwise pulverizer work, identical to overcome the coaxial or synchronous rotational speed of two machines, one machine work, machine idle running consumes idle capacity, thus the efficient when improving complete machine power utilization and husk rice, pulverizing.The power of motor of unit is 2.2KW, 2800 rev/mins of single-phase 220 volt of 2 utmost points, the rice milling machine principal axis rotating speed is 1800 rev/mins, rotation speed of fan is 4900 rev/mins, the pulverizer rotating speed is 7100 rev/mins, pulverizing chamber width 92mm, the maximum widely different commentaries on classics diameter 200mm of hammer leaf, the gearratio of electrical machine belt pulley and rice mill, pulverizer belt wheel was respectively 1: 1.56,2.54: 1.Be contained in the dental lamina (10,14) in the pulverizer pulverizing chamber; not only pulverizer shell (19) is played the safeguard protection effect, main is when undertaking material to be machined and hit by hammer leaf to collision, the reflection of material, hit, make material become the function of particulate by hammer leaf again.The tangential direction out of plumb of traditional pulverizer dental lamina tooth form angle size unanimity, working face and the widely different commentaries on classics diameter of hammer leaf is to making above-mentioned functions poor.The dental lamina structure of pulverizer is seen Fig. 2 in the utility model unit, (wherein Fig. 2 is preceding dental lamina to Fig. 3, Fig. 3 is the back dental lamina, chain-dotted line among the figure is represented the maximum widely different commentaries on classics diameter circle (11) of hammer leaf, arrow is represented the widely different veer of hammer leaf), tooth form angle (12,13) along with the widely different veer of rotor by diminishing greatly gradually, and the working face at each the tooth form angle all tangential direction hammer with the maximum widely different commentaries on classics radius of circle of hammer leaf is straight, dental lamina is to the collision of material when hit by hammer leaf to reach material to be machined, reflection, hit by hammer leaf again, collide the optimum efficiency that becomes particulate with dental lamina again, thereby improve pulverizer productivity ratio.Pulverizing chamber is the heart of pulverizer, when traditional pulverizer only rotates according to rotor high-speed, material in the pulverizing chamber is subjected to the strike of hammer leaf, the rubbing action of the collision of tooth plate and sieve sheet and be ground into particulate, from sieve aperture, leak down, the operation principle that carries out by the haul blower fan, and ignored to collision, the kinetic energy that plays a decisive role of friction and power, with the material fragmentation after the variation of quality and the relation of distance, cause the pulverizing chamber unreasonable structure, cause low, the bad adaptability of pulverizer crush efficiency.The utility model is exactly according to above-mentioned relation each other, determines the structure of pulverizing chamber scientifically and rationally, reaches efficient, energy-conservation, express, the adaptable purpose of pulverizer.The pulverizing chamber of Fig. 4 mainly is made up of cover (19), preceding dental lamina (10), sieve sheet (21), back dental lamina (14), rotor (20).Material to be machined is by feed hopper (16), enter pulverizing chamber through charging control panel (17), hit by the hammer leaf (53) of rotation at a high speed, dental lamina (10) flies and collision with it forward, particle after the fragmentation reflects to hammer leaf (53), hit by hammer leaf (53), reciprocation cycle also rubs with it and collides to sieving sheet (21) and back dental lamina (14), becomes particulate.Starting stage, the quality of material is big, kinetic energy and active force are bigger, the distance of widely different commentaries on classics diameter of hammer leaf and preceding dental lamina increment is also big in the requirement pulverizing chamber, along with particle collision, friction become particulate, particulate less than sieve diameter leaks down along sieve aperture, and all the other then enter different crushed zones along the widely different commentaries on classics circumferencial direction of rotor.Because particle constantly overwhelms, collision, friction effect, quality is more and more littler, the speed of hammer leaf is certain, granular mass is little, kinetic energy is little, overcome the resistance in the motion process, require corresponding distance also must change, be ground into the requirement that particulate is directly proportional with kinetic energy and active force to adapt to strike, collision, friction effect by rule.The utility model is exactly to make the gap of pulverizing chamber physical dimension transfer between the widely different commentaries on classics diameter of maximum and cover (19), preceding dental lamina (10), sieve sheet (21), back dental lamina (14) from large to small and the different off-centre by preceding dental lamina (10), sieve sheet (21), back dental lamina (14) and the widely different commentaries on classics axial line of rotor by such operation principle, makes its gap area be volute type (22) (see figure 5).Such setting, the hammer leaf of rotation is at a high speed also worked with the centrifugal exhaust fan one that transports finished product at the stronger blast of pulverizing chamber bottom formation, by force the particulate less than sieve diameter is passed the sieve aperture of sieve sheet (21), deliver in the collection flour bag, avoid it to continue to be hit dental lamina collision, the friction of sieve sheet etc. and consume unnecessary power by hammer leaf.Make the cover pulverizing chamber near charging aperture (16) position formation low pressure vacuum in contrast simultaneously, produce bigger pressure differential with external pressure, if regulate the charging control panel to the promptly externally atmospheric pressure of certain position, material to be machined by charging aperture (16) automatic feed.In addition, processing materials is rotated the heat that friction conducts to main shaft at a high speed by strike, collision, friction, fragmentation and bearing in pulverizing chamber, through the constantly additional air flow of charging aperture, the ground warp sieve aperture is pulled away continually, prevent the heating of pulverizer fuselage, reduced bearing and finished product temperature rise to greatest extent.Cover is provided with paddy mouth envelope stock cap (18) (see figure 4) near the top of preceding dental lamina (10), and stock cap (18) is arranged with a paddy mouth Pai Chi hole (54).The paddy mouth is both hard and tough, not only is unfavorable for the digestion of livestock and poultry, and extremely difficult the pulverizing.When processing cavings or not plump paddy, when its with after the chaff sheet separates, owing to it is not crossed sieve aperture greater than sieve diameter and is forced to rest in the pulverizing chamber, cause cumulative, cause pulverizer productivity ratio to descend, occur seeing plug, anti-material when serious even burn motor, the user has a headache the most.The purpose of offering this hole is exactly in order to solve this difficult problem.Because paddy mouth quality is bigger than chaff sheet, and volume ratio chaff sheet is little, after being subjected to hammer leaf strike or dental lamina collision, kinetic energy is big, fly or rebound to paddy mouth Pai Chi hole, open paddy mouth seal closure, just obtained in time having reduced its time of staying in pulverizing chamber and the power of required consumption, thereby pulverizer crush efficiency and adaptability being increased substantially to effluxing the pond.At present family expenses of producing or joint household are pulverized pulverizer and cover thereof in the unit with husk rice, support is made and is still adopted the traditional material of big-and-middle-sized pulverizer, technology and structure, not only operation is many, complex process, productivity ratio is low, the cost height, heavy, and manufactured materials adopts traditional cast iron, its fragility is big, plasticity and poor toughness, tension, a little less than the bending resistance, not shock-resistant, easily cracked, just in case a certain parts depreciation of high speed rotor rotated, in pulverizing chamber, come off or throw away, not only damage dental lamina and sieve sheet etc., even a series of chain reactions can appear, hit mashed cover or support, if the abrasive grit after cracked, fragment, iron block to around fly, gently then lose property, heavy then cause casualties.The dangerous accident that occurs mostly is this situation.The utility model is exactly at above-mentioned existing problems and hidden danger, with safety first, put prevention first, adopts new material, new technology and new construction.Embodiment is: make on the raw material; select mechanical strength height, plasticity good toughness, wear-resisting, shock-resistant, tension, bending resistance, shatter-resistant and certain thickness quality carbon structural steel manufacturing for use;, be the second road safety net, dual security insurance is set as the first road safety protective net with dental lamina, screen frame, sieve sheet reference column, sieve sheet with cover, support.In the technological process, cover, support adopt sub-assembly, and after blanking respectively, stamping-out, moulding, assembly welding is an one on pattern again.Fig. 6, the 7 support constitutional diagrams for pulverizer in the utility model unit: support, cover detent rail (23), sieve sheet end face reference column 1 (24), locking bed (25), right wallboard (26), squab panel (27), front panel (28), reinforcement (29), support connecting plate (30), base plate (31), left wallboard (32), sieve sheet end face reference column 2 (33), hinged-support (34), reinforcement (35), bearing block support plate (36) totally 14 kinds of basic modules combine.Combination front panel, squab panel are seen Fig. 8,9, firmly are one by screen frame (37), (38) with front and rear wall spot welding on pattern respectively.Screen frame is that round iron wire or square iron forms through bending by the cross section, forms the radially semicircle annular groove of wide about 2mm of gap between two screen frames (37,38), is used to install the sieve sheet (21) of different apertures and thickness.Front panel (28) below offer one with the interior hole shape rectangular through holes identical of the big end of the lower air conduit that transports finished product with sectional dimension, the horizontal center line in hole is provided with 2 and connects the screw of using when fastening with lower air conduit; The below of squab panel (27) also offers an area of section and approximates the former 1/3rd, and length is offered a screw than the former bigger slot on the top vertical center line in hole, be used for air-flow plate unlatching, close, adjusting and fastening.The below of sieve sheet end face reference column 2 (33) offers a ladder (see figure 10) that the mutual vertical openings in two sides is downward, and the end face of ladder is as the circumferential location of sieve sheet, and side and screen frame are together as the radial location of sieving sheet.Sieve sheet end face reference column 2 (24) (seeing Figure 12) are a rectangle square steel, main circumferential location and fastening (see figure 4) as the sieve sheet.The sieve sheet is made the semicircle that cornerite is slightly less than 180 °, and left side direction and circumferencial direction overlap, crooked backward about 90 ° of right sides along horizontal diameter, and the bent flat face length is slightly less than the width dimensions of sieve sheet end face reference column 1 (24).During sieve sheet (21) assembling, as long as its left side is pushed into gently the ladder mouth end face of sieve sheet end face reference column 2 (23) along the ring shaped slot in the support front and back wallboard screen frames (37,38), sieve sheet (21) has just obtained radially and circumferentially locating accurately, after assembling of cover and support and locking, the bottom surface that is installed in the back dental lamina (14) of cover inner just will be sieved sheet (21) right side compacting and it will be lock onto in the support screen frame (37,38) securely.When sieve sheet (21) dismounting maybe need be changed, as long as unclamp the locking nut on the left side, open cover (19) (seeing Fig. 4, Figure 13), do not use any instrument, only need to exert oneself a little round about, sieve sheet (21) can take out easily.Such technology and structure not only make screen frame (37,38) and ring shaped slot that sieve sheet (21) usefulness is installed realize no machining, and the assembling and dissembling speed that sieves sheet compares fast 5～30 times with other uniform machines, greatly facilitate the user.In addition, new material, new technology and the new construction of implementing by above-mentioned support, cover (19) not only mutual alignment and dimensional accuracy is accurate, guarantee the uniformity of each machine performance, and the productivity ratio height, product is easy to mechanization and automation, alleviate labor strength, satisfy mass production, reduce cost and user's requirement, simultaneously through repeatedly destructive testing repeatedly, all reach safety requirements, eliminated hidden danger.Roller (46) is the heart of rice mill, is not only determining the running parameter and the performance of rice mill, and affects the structure and the volume of other parts.At present family expenses of producing or joint household are pulverized rice mill and corresponding unit thereof in the unit with husk rice, its roller unreasonable structure, only pursue major diameter, unrealistically compare mutually with the rice mill roller that power is of the same type, do bigger and bigger, not only cause big, the swelling kind of rice mill and unit volume thereof, and the no-load power liter, precision of rice is poor, degradation under the performance indications.The utility model designs and implements at above-mentioned roller structure existing problems.Purpose is to reach with uniform machines to compare, and compact conformation, little, the every economic technology performance indications of volume reach optimum efficiency, energy savings and raw material, satisfy user's requirement simultaneously.With reference to Figure 14～17, roller (46) is circular arc, wide 3～4mm, the wide 8mm in bottom surface by 3 end faces, even cloth is on about 1: the 20 same Rotary-table surface of end diameter 42mm, outside diameter 54mm, tapering, and screw propulsion diagonal bar and the pearling straight muscle (42,44) of end face on the same diameter 64mm face of cylinder formed; The long 242mm of roller (46), draw ratio 3.78mm; About 18.2 ° of screw propulsion diagonal bar inclination angle, helical pitch 66mm, about 7 ° of pitch 22mm, working face and widely different commentaries on classics kernel of section wire clamp angle; 3 ° at inclination angle, the direction of straight muscle and axial line is identical with diagonal bar, cross section (seeing that Figure 16 C is to view) worked and overlapped with radius of gyration; Diagonal bar is a circular arc with straight muscle non-working surface.Every the screw propulsion diagonal bar joins around terminal and straight muscle top, one week of round platform surface back by the inclination angle, the joint is for avoiding the dead angle and axial force occurs and resistance sharply changing, paddy husking produces widely different stream, and consumed power and making respectively with diagonal bar and straight muscle is passed through or tangent circular arc, cylinder or sphere mutually.Offer 4 cylindrical shoulder hole and truncated cone-shaped holes that diameter is different on the inner same axial line of roller (46), one of them less cylindrical hole has keyway, this cylindrical hole and left side thereof and is mainly used in when rice milling machine principal axis (48) is installed as radial and axial location and the transferring power and the moment of torsion of roller (46), and the round platform hole is used to assemble and axial restraint and the self-locking (see Figure 18) of main shaft locking nut together as roller.

See Fig. 1 during rice mill work: the belt pulley rotation on the driven by motor rice machine main shaft, main shaft and roller rotate together, the paddy that enters through the cover charging aperture by feed hopper, (see (17 of Figure 14 through spiral propeller diagonal bar larger axis to the effect of power, 18) push the stone roller chamber continuously along helicla flute, when arriving diagonal bar and straight muscle handing-over circular arc district, axial force diminishes, tangential and radial load increases, at the rice cutter, rice huller screen, cover, the synergy of roller is shelling down, separate, form brown rice, husk, the mixed flow of chaff sheet also enters whitening chamber under the effect of axial force, because roller and the straight muscle (44 of pearling, 45) special construction, mixture is fully stirred in whitening chamber, roll, extruding, friction, brown rice becomes pure white rice.Tablet screening machine covers the consistent semicircle column type that is of each internal diameter, constant after rice cutter and the gap adjustment of roller rib cylindrical, ascending by roller round platform column diameter, grind muscle cross section and highly from large to small, chamber roller and cover are ground in control, the rice cutter, the space of rice huller screen is by diminishing greatly gradually, to adapt in the mixed flow motion process because of extruding, friction and less than the young chaff of sieve aperture, the chaff sheet, rice broken from sieve aperture leak down the back density variation consistent, keep from start to finish in the whitening chamber, between the grain of rice and the grain of rice, extruding mutually between the grain of rice and the whitening chamber parts, radially needed during friction, tangentially, axial compressive force is constant substantially, be subjected to grind evenly.The special setting and the structure of diagonal bar, straight muscle working face, mainly be to quicken stirring of grain, the grain of rice, make grain husking, decortication, pearling even, the precision of rice unanimity forces thick, children, thin chaff less than sieve aperture simultaneously, cracks rice and in time leak down, reduce its repeating motion and friction consumed power from sieve aperture.Such setting, not only dwindled the diameter and the volume of roller effectively, and given full play to the function of roller, support and cover technology and structural requirement are simplified, volume has obtained corresponding minimizing, thereby makes the more compact structure of other mutual parts with rationally.Cover, support inner chamber and structure are seen Figure 19, Figure 20.On the air exhauster Fan casing air inlet flange that works with rice bran separator one, an air-flow plate (seeing Figure 21) is set, air-flow plate moves right along air inlet flange groove, and open greatly in the air port, otherwise turn down.When being used to regulate the separation of separator rice bran, because of in rice mill processing paddy quality difference, time, produce difference, required separation air quantity difference and make it reach the optimal separation effect, be unlikely to rice again and suck blower fan with the chaff sheet, deliver to collection chaff bag, influence rice milling yield, with reach control power of fan and rice bran separate institute's required airflow mutually one to best purpose.Husk rice pulverize the clean quality of unit (not comprising motor) only 50Kg, appearance and size long * wide * during high workload: 746 * 584 * 1000mm, during packing: 746 * 454 * 1000mm, with compare clean quality and volume with power machine of the same type and lack 35～100%, 25～70% respectively, have compact conformation, novelty, in light weight, characteristics such as volume is little.Through performance test, every economic technology performance all is better than national mechanical industry JB/T51195-1999, JB/T51213-1999 standard.Wherein, the paddy time processing become pure white clean rice ton material power consumption (KW.h/t) 7.6, nominal power productivity ratio (Kg/kw.h) 136～159, equivalent rice milling yield reach 72～74%, unit-hour output 300～350Kg, with existing with the power uniform machines compare the equivalent rice milling yield high by 2～4%, the time produce high by 40～75%, precision of rice is good, rate of bran content, rate of unhulled rice, broken rice rate, dust concentration, finished product temperature rise are little, it is reliably convenient to use.Pulverize and now compare with power unit and unit thereof of the same type, require that strong 0.3～0.7 times, ton material of the different adaptability of grain thickness degree power
