The rice sector of novel adjustable Milling degree
Technical field
The present invention relates to a kind of agricultural machinery, relate in particular to a kind of novel adjustable Milling degreeRice sector.
Background technology
Normally, the harvested grain of rice need to carry out seed coat to be peeled off and just can become the grain of rice, thisProcess is generally referred to as husk rice at agricultural production. In fact, paddy is removed the thickness of seed coatCan have influence on the quality of the grain of rice, if the thickness that seed coat is peeled off is more shallow, from rice mill out beThe grain of rice is exactly brown rice, if the thickness that seed coat is peeled off is darker, from the rice mill grain of rice is out exactlyPolished rice. But, because the personnel of different mouthfeels require difference to the thick degree of the essence of the grain of rice, thereforePeople more favor in the grain of rice of the edible thick degree of self-defining essence. Current rice mill is not muchAdjustable Milling degree, or regulate that to roll the mode of precision too simple, accommodation accuracy is low,More there are dependence staff, dependence experience to regulate the rice mill of Milling degree. Significantly, existingRice mill in technology all fails to reach the requirement that controllably regulates Milling degree, still can not meetThe demand of the edible rough degree of self-defined essence of people.
Summary of the invention
For the deficiencies in the prior art, object purport of the present invention provides a kind of novel adjustable husk riceThe rice sector of precision, for flexibly, regulate and peel off the thickness of grain of rice seed coat more accurately,The personnel that are embodied as different eating requirements provide the grain of rice of the thick degree of suitable essence.
For achieving the above object, the present invention adopts following technical scheme:

Detailed description of the invention
As shown in Figure 2 and Figure 3, the rice sector of novel adjustable Milling degree, comprising: shellBody 10, pressing plate 21, spring 22; The first motor 20. Described housing 10 is hollow, shouldIn housing 10, be provided with husk rice sieve 11, husk rice axle 12, movable pressing plate 21, for sending intoThe feeding-passage 13 of the grain of rice, for collecting the discharging chamber 2 of the grain of rice, the barrel of described husk rice sieve is establishedBe equipped with multiple for peeling off the sieve aperture of grain of rice seed coat, on this husk rice sieve 11 near feeding-passageOne end is storage end, and these husk rice sieve 11 one end near discharging chamber 2 are discharge end, described stone rollerRice axle 12 is connected in husk rice sieve 11, and described pressing plate 21 is positioned at discharge end, these pressing plate 21 limitsBetween edge and husk rice sieve 11, there is the gap of discharging the grain of rice. On described spring 22, be provided with screw mandrelNut, the other end of spring 22 is fixed in pressing plate 21; The shell of this first motor 20 is fixed onHousing 10, is provided with screw mandrel on the clutch end of this first motor 20. Described the first motor20 for the rotary power that makes screw mandrel rotation is provided, another side, and feed screw nut is connected in bulletOn spring 22, therefore, the rotary power of the first motor 20 is by screw mandrel, feed screw nut and spring22 cooperation crush board 21 sieves 11 discharge ends in husk rice and axially moves, and 11 interior stone rollers are sieved in husk riceRice pressure is understood the variation on axial displacement because of pressing plate 21 and is changed.
Operation principle of the present invention is as described below: the grain of rice enters into husk rice sieve from feeding-passage 1311 storage end, now husk rice axle 12 constantly pushes to discharge end by the grain of rice,, grinds meanwhileThe grain of rice between rice axle 12 and husk rice sieve 11 can produce friction mutually, between the grain of rice and husk rice sieveAlso can mutually produce friction, therefore, the seed coat of the grain of rice can be deviate from, and, because the grain of rice is full ofIn husk rice sieve 11, the directly impact of pressure that pressing plate 21 acts on husk rice and sieves 11 discharge endsTo the thick degree of the essence that rolls the grain of rice, if wish to obtain the meticulousr grain of rice, can be by the first electricityMachine feed screw nut promotes spring 22, and spring 22 promotes pressing plate 21 toward near husk rice sieve 11Direction regulates, if wish to obtain more coarse unpolished rice, toward the direction away from husk rice sieve 21Regulate.
As shown in Figure 3, due to the basis that pressing plate 21 needs suspention and installs, excellent as oneThe scheme of choosing, the rice sector of this novel adjustable Milling degree also comprises for hanging activelyThe suspended structure of pressing plate 21, described suspended structure comprises that a peg 23 and is positioned at housing 10Go up near discharge end and be positioned at the recess that discharge end top is located, described peg 23 is " C " type shape,One end of this peg 23 is connected in pressing plate 21, and the other end is connected in recess actively.
As the preferred scheme of one, between these housing 10 inwalls and husk rice sieve 11, form a collectionChaff chamber 40, the lower end of this housing 10 offers the row's chaff mouth 41 for discharging grain of rice seed coat detritus,These row's chaff mouth 41 places are provided with centrifugal impeller 42, and this centrifugal impeller 42 is for by grain of rice seed coatDetritus is drawn to housing 10 outsides.
As the preferred scheme of one, the rice sector of this novel adjustable Milling degree also comprisesThe second motor 30, this second motor 30 is used to husk rice axle 12 that rotary power is provided.
In order to simplify the structure of transmission mechanism, as the preferred scheme of one, described the second motor30 clutch end is provided with the first belt pulley, and described centrifugal impeller 42 has rotating shaft, shouldThe second belt pulley is installed in rotating shaft, between the first belt pulley and the second belt pulley, passes through belt31 connect. By bel-drivenn mode, centrifugal impeller 42 and 12 synchronous interactions of husk rice axle.
As shown in Figure 4, carry out closed loop in order to realize the displacement in husk rice sieve 11 to pressing plate 21Control, as the preferred scheme of one, the rice sector of this novel adjustable Milling degree also wrapsDraw together a D.C mutual-inductor for detection of the second current of electric size and a single-chip microcomputer electric-controlled plate, instituteThe signal output part of stating single-chip microcomputer electric-controlled plate is electrically connected by wire and the first motor 20, instituteThe signal receiving end of stating single-chip microcomputer electric-controlled plate is electrically connected by wire and D.C mutual-inductor. GrindingWhen the work of rice machine, single-chip microcomputer electric-controlled plate is according to the second motor perceiving from D.C mutual-inductorCurrent value, extrapolate the current grain of rice and accept to roll by being stored in Mathematical Modeling in single-chip microcomputerFriction force value, then contrast the corresponding friction force value of set Milling degree, judge currentWhether frictional force that what the grain of rice was accepted roll is suitable, if numerical value is excessive/too small, by monolithicElectrical Control plate sends regulating command, and this regulating command by wire transmission to the first motor 20 alsoThe first motor 20 is rotated. The number of turns that regulates the first motor screw mandrel to rotate according to this regulating command,Crush board 21 moves to suitable position. Thereby realize closed loop, automatically regulate husk rice essenceDegree.
The rice mill with the rice sector of novel adjustable Milling degree, comprising:
Frame 3, described rice sector 1 is installed on frame 3;
Collection chaff bag 5, described collection chaff bag has sack, and this sack is socketed on row's chaff mouth 41;
Be positioned at the grain storing box 4 of housing 10 tops, described grain storing box 4 has blanking port, and this fallsMaterial mouthful is communicated with described feeding-passage 13.
To one skilled in the art, can be according to technical scheme described above and design,Make other various corresponding changes and deformation, and all these changes and deformation are all answeredWithin this belongs to the protection domain of the claims in the present invention.
