Description

Combined rice mill by milling, hulling and sifting

The utility model belongs to a kind of small-sized milling, hulling and sifting combined rice mill that is suitable in the use of common peasant household.

Existing family expenses rice mill generally all can not directly go out rice, promptly also must use rice huller to wait utensil with husk again, and remaining rice bran etc. are removed just can boil usefulness.Though " domestic miniature combined rice mill " (sees＜utility model patent communique〉the 4th 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 design grind roller bearing to and adjusting device shrouded by a casing, 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.

The purpose of this utility model is to propose a kind of simple in structure, and stressed reasonable, the one step completed combined rice mill of milling, hulling and sifting easy to adjust is to overcome the shortcoming of prior art.

This rice mill organic frame that the utility model proposes, lower box, upper box, stone roller rolls, the rice cutter, sieve sheet, feed hopper, the charging tongue, rice output outlet, the necessary parts of existing common rice mills such as adjusting tongue, improvements are 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 (rice huller falls).The hair-dryer casing be one cylindric, an end has individual upper shield outwardly, play safety effect, cover covers and has the hole, so that air draught, the phoenix tube is led in weldering on the casing, and the supporting slice that whole hair-dryer is fixing, screw hole is arranged on the supporting slice, grind on the roller bearing bearing so that be installed in, the blade that the fan of hair-dryer generally has the 2-4 sheet all to distribute, its center have axis hole (having keyway or square hole), and fan directly is fixed on by a threaded straight-bar and grinds on the rotating shaft end face that rolls (having an axial thread hole on the end face).

Stone roller rolls and is bearing in, and (passes through rolling bearing) on the bearing block at lower box two ends, and one section that is positioned at charging aperture has two strands to play propelling movement and grind the spiral of the effect of rubbing, and another section has three to grind muscle, and the stone roller muscle favours axial line and arranges.It is a semicircular groove that upper box bag cage grinds the part of rolling, groove is in the place that is positioned at rice output outlet, one one of this arch or all upwards suitably expand and stretch, make its space big slightly, effect is grain that this place also do not shell and rice to be had rub mutually or return the chance of grinding again, to grind the whiteness of removing husk and increasing rice as far as possible.

The power of this combined rice mill is generally used single-phase AC motor or the small diesel engine (or gasoline engine) of 0.8-2.0KW, by the belt pulley transmission.Machine during use to working well, drop into cereal again, regulate a rice cutter, charging tongue and rice output outlet are till grind the Mi Hege that.Rice bran and capes shell major part in stone roller rubs process are passed the chaff sieve and are flowed out lower box; after the mixture of rice husk and remaining rice bran flows out from rice output outlet; the wind that is blown out by hair-dryer in the process that falls is loose; husk and rice bran are blown on one side; the grain of rice falls along straight line substantially; rice and chaff have so just been realized, the separation of husk.

The utility model has the advantages that: adopt by the hair-dryer rice huller rice structure of grinding direct drive of wobble shaft and coaxial arrangement, simple than existing technology, compact, stone roller rolls to have been improved by the bearing block support (passing through rolling bearing) of tank ends up and down and grinds the stress condition that rolls, roll at stone roller the charging bifilar helix is set, the suitable expansion in the space of upper box rice output outlet helps even stone roller of cereal and rubs, and improves rice milling yield.Said device features rational structure in addition, volume is little, and weight is below 30Kg.Adopt load motor or the oily function of small-sized bavin (vapour) to promote the use of in vast rural households.
