Abstract
The utility model discloses a vacuum husking machine for grain, belonging to an agricultural grain processing machine, which uses the method of vacuum resulting in pressure difference to husk the grain so that the rate of husking of the grain is increased, the rate of rice breaking is lowered, the noise is decreased, and the cost is reduced. The machine is provided with two vacuum chambers. When the grain passes through the impeller of the vacuum chambers in sequence, the external pressure is lost. The grain is blasted by virtue of the different pressure, because the pressure between the rice grain and the husk doesn't change. The utility model can be widely used in the husking for grain, in particular to the husking for paddy.
Description
The utility model belongs to a kind of agriculture cereal processing equipment, is widely used in the shelling of cereal, especially for the shelling of paddy.
Known cereal hulling machine (referring to United States Patent (USP) B02B3/12US03301292 in 1967) is made up of an annular compartment, the air inlet mouth of pipe, several air overfalls, hopper and the turnover cereal mouth of pipe.In the air inlet mouth of pipe convergent nozzle is housed, adjustable valve is equipped with in grain inlet and exit.This hulling machine be when high velocity air make during by nozzle trunnion place air-flow near or reach velocity of sound, tangential direction along annular compartment enters chamber then, air-flow impels grain to rotate at a high speed along the outer wall in the chamber, because the vibration of the friction of friction, grain and the high velocity air of friction, grain and chamber wall between the grain and sound wave makes the cereal shelling.
This hulling machine needs the auxiliary equipment of a generation high velocity air, as air compressor etc., making the pressure at air inlet mouth of pipe place reach 1.06~2.8 Kilogram Force Per Square Centimeters can, because the sound of auxiliary equipment and the above-mentioned various frictions that high velocity air causes, the vibration that more has sound wave to produce is so noise is bigger.Cereal rubs inhomogeneously in annular compartment again, and the time is inequality, and the grain long for fraction time easily goes out to crack rice, and the short husking yield of fraction time is relatively poor, and wherein not full grain more so.
The purpose of this utility model is to eliminate above-mentioned shortcoming, both improving husking yield and reducing under the situation of broken rice rate, does not add auxiliary equipment, reduces cost, and reduces noise, and except that with the Motor Drive, diesel engine also can be used as power source when non-transformer.
For reaching this purpose, adopt the principle of vacuum shelling, promptly utilize the centrifugal impeller of rotation at a high speed to form the region of no pressure, when cereal passes through the region of no pressure, lose or reduce the pressure of husk outside, and the inner original interior pressure of cereal is constant, utilize the pressure official post cereal shelling of instantaneous generation, more thorough in order to shell, two vacuum chambers 6,13 (Fig. 1 shows) are arranged in the fuselage, be provided with adjustable half-ball valve 4 in first vacuum chamber, 6 porch, the below of valve 4 be provided with replenish air door 5, the second vacuum chambers 13 with separable whole meter, crack rice and the separator box 19 of cavings communicates.
Fig. 1: the profile and the partial longitudinal section of vacuum cereal hulling machine.
Fig. 2: the blade figure of impeller in first vacuum chamber.
Fig. 3: the blade figure of impeller in second vacuum chamber.
Fig. 4: the K on accompanying drawing 1 top is to partial enlarged drawing.
The utility model embodiment (Fig. 1 shows): half cone-shaped hopper 3, half-ball valve 4 link to each other the restriction of the limited adjustment range making sheet 1 of regulating handle 2 by connecting rod, shift fork with regulating handle 2.Belt pulley 14 directly is contained on the main shaft, can be driven by motor or diesel engine.As when adopting Diesel Driven, speed adjusting lever links to each other with the diesel engine oil door switch by rope, moves handle 16 and can regulate revolution, and numerical value is directly read from revolution counter 17.Before the shelling, adjustable half-ball valve 4 is in extreme lower position, and the cereal passage is blocked.At this moment, fill up cereal in half cone-shaped hopper 3, doing wets all can.When the speed of mainshaft reaches 1700 rev/mins, mention half-ball valve 4 by moving regulating handle 2, cereal just is inhaled into first vacuum chamber 6, begins shelling.Along with the rising of half-ball valve 4, advancing the paddy amount increases gradually.The cereal husking yield of discharging from first vacuum chamber 6 can reach 95%, enters second vacuum chamber 13 through conveyance conduit by the axis direction of main shaft again and carries out shelling second time, and husking yield can reach 98~100%, afterwards, enter separator box 19(Fig. 1 K to).Separator box 19 is made up of the fixing partition (Fig. 4 shows) with adjustable of multiple tracks, and adjustable partition 20 and 21 is used for adjusting angle and stroke respectively, to reach the optimum state of separation.Owing to rice, crack rice and the varying in weight of cavings, whole rice is discharged from rice output outlet 18, cracks rice and mouthfuls 15 discharges through cracking rice of showing of Fig. 1 from passage 22.Fan house 9(Fig. 1 shows) in centrifugal blower 10 is housed, the axial inlet of centrifugal blower communicates with the cavings passage 23 that Fig. 4 shows, because the suction of blower fan sucks lighter cavings, from the tangential direction discharge of blower fan.
Because the utility model has adopted the principle of vacuum shelling, compare with known husking machine for grain and be not that not only husking yield is higher by rubbing and acoustic vibration, can reach 98~100%, surpassed national standard, and broken rice rate is lower, has more preserved the nutritious plumule part of cereal. Reduced noise, part is difficult for friction, increases the service life. Because no auxiliary equipment, and first separation rice, crack rice and cavings, again most of part employing plate sheet welding and working of plastics are so cost is low. During Motor Drive, 2.2 kilowatts of power is, and in the available Diesel Driven in power free place, power is 4 horsepowers.
