Description

Four-separating combined rice mill

The utility model belong to a kind of be suitable in the rural area generally using miniature four separate combined rice mills.

Existing family expenses rice mill generally all can not directly go out rice, promptly also must be with utensils such as rice hullers with husk, and remaining rice brans etc. are removed just can boil usefulness." though domestic miniature combined rice mill " (see＜the utility model patent communique〉the 4th the volume No. 31,1987.8.5) solution that the husk rice huller is gone proposed on same machine, but this scheme makes this combined rice mill structure complicated, will be with a long drive link as fan blade, the belt pulley belt pulley transmission of grinding on the roller bearing, unnecessary wind-gathering device, wind-force is not concentrated, be not enough to husk is blown to the greatest extent, rice output outlet designs on the stone roller roller bearing and adjusting device is shrouded by a casing, and inconvenience is in time regulated.Two drive bearings that stone roller rolls are arranged in and grind the same end roll and be cantilever-shaped, this rolls for the less stone roller of rotating shaft, stressed unreasonable, be easy to generate bending, grind in the elongated rotating shaft of rolling because two belt pulleys all are placed in, under unexpected situation (when sneaking into rigid foreign material in as cereal), twist off easily or fracture or the like.

" though milling, hulling and sifting combined rice mill " (see＜the utility model patent communique the 8th volume patent No.: 91227640.1) a last utility model has been done further improvement, be equipped with directly by grinding the hair-dryer that wobble shaft drives at rice output outlet one end, be equipped with one on the hair-dryer with the lead ventilating duct of rice output outlet of wind, so that when going out rice, husk in the rice and remaining chaff are blown away.But when separating, crack rice and can not separate from qualified rice, chaff and thin chaff can not be separated simultaneously.

It is reasonable that the purpose of this utility model is to propose a kind of compact conformation, can make qualified rice, cracks rice, chaff, thin chaff is disposable finishes, and reach the combined rice mill that four kinds of different materials separate, to overcome the shortcoming of prior art.

This rice mill that the utility model proposes is made up of the necessary parts of existing rice mills such as frame, rice channel parts, roller, rice cutter, rice huller screen, feed hopper, adjusting tongue, air exhauster, its improvements are to be equipped with at rice output outlet one end one can make rice, crack rice, chaff, the thin disposable separator of finishing of chaff, separator is connected on and grinds between axle (roller) and the air exhauster, one end is connected in the following stone roller case of roller, and the other end is connected on the roller left shaft holder.When machine run gets up, drop into cereal from feed hopper, regulate the rice cutter, make it can grind qualified rice, in grinding the stripping process, thin chaff is below rice huller screen is fallen down the stone roller case, rice, crack rice, chaff grinds by roller and enters a meter groove after the stripping and be admitted to separator, in dropping process, rice is directly fallen broken rice sieve and is separated on the net with cracking rice, rice on the sieve is gone out from the polished rice groove, and cracking rice under the sieve gone out from the groove of cracking rice; The remaining thin chaff of chaff and part enters the chaff road under the draft effect of air exhauster, discharge through air exhauster.So just realized qualified rice, cracked rice, the separation of chaff, thin chaff.

The utility model has the advantages that: after adopting separator, make it more reasonable structure, compactness, easy to use and reliable, in light weight, solved the problem of cleaning that rice bran separates with simple structure, widely applicable (all can use) as long as the place of single-phase electricity is arranged, compare with existing rice mill, its equivalent rice milling yield exceeds 4-6 percentage point than like product, and rice containing amount reduces 50% in the rice finished product, wherein the small brokens rate can be less than or equal to 2.5%, and the machining accuracy of rice is equal to or higher than " marking 1 grade ".

The utility model is described in further detail below in conjunction with accompanying drawing:

Accompanying drawing 1 is a front view of the present utility model;

Wherein among Fig. 1-8,1-air exhauster, 2-left bearing, 3-rice-supplying slot, 4-separator, the last stone roller of 5-case, 6-regulate tongue, 7-and regulate tongue screw, 8-feed hopper, 9-right bearing, 10-and grind axle, 11-rice mill belt pulley, 12-belt, 13-motor pulley, 14-motor, 15-motor fot screw, 16-frame, 17-crack rice screen cloth, 19-chaff road, 20-roller, 21-rice huller screen, 22-crack rice groove, 23-polished rice groove of stone roller case, 18-down.

Embodiment:

When the utility model plugs in, open machine, (necessary electromotor power 1.1KW just often has a machine in operation, 1330 rev/mins of rotating speeds), drop into cereal from feed hopper (8), regulate the rice cutter, make it can grind qualified rice, in grinding the stripping process, thin chaff is below rice huller screen (21) is fallen down stone roller case (17), rice, crack rice, enter rice-supplying slot (3) after chaff is shelled by roller (20) stone roller and be admitted to separator (4), separator (4) is connected on and grinds between axle (10) and the air exhauster, and an end is connected in roller (20) (roller specification (diameter * length) φ 56 * 245mm, rice huller screen specification: 249 * 1.5 * 1mm) following stone roller case (17), and the other end is connected on the left shaft holder (2),, in dropping process, rice separates with cracking rice directly to fall on the screen cloth of cracking rice (18), rice on the sieve is gone out from polished rice groove (23), and cracking rice under the sieve gone out from the groove of cracking rice (22); The remaining thin chaff of chaff and part enters chaff road (19) under the draft effect of air exhauster (1), discharge through air exhauster (1).So just realized polished rice, cracked rice, the separation of chaff, thin chaff.

The utility model is rational in infrastructure, compact, complete machine overall dimensions (length * wide * height) 600 * 480 * 550, in light weight, 40kg only, the unit power of this machine and productivity ratio＞70kg/kwh, equivalent rice milling yield 〉=66%, wherein small brokens≤2.5% of % total amount≤39%(of cracking rice in the rice), 6/kg of rice containing amount, rate of bran content≤0.2%, precision of rice 〉=" marking 1 grade ".
