Abstract
The utility model discloses a differential double-roll rice polisher which comprises a stand and a machine shaft arranged on the stand, wherein an inner roll is arranged on the machine shaft and adopts a sand roll spliced by grinding wheels in a stringed manner, a screw conveyor and a transitional grinding wheel are arranged at one end of the sand roll, air-jetting diagonal bars and an air-jetting hole are arranged and formed between the grinding wheels and respectively parallel to the axial line of the inner roll to form an included angle of 62 degrees, and the air-jetting diagonal bars have three specifications (6, 3 and 2); the inner roll is driven by a belt pulley on the machine shaft, a cylindrical polishing outer roll which is provided with a carborundum inner surface and is capable of making differential rotation with the inner roll in the same direction is sleeved outside the inner roll to form double rolls, and the clearance (keep gas) between the roll surfaces of the inner roll and the outer roll is the same as that of the conventional rice polisher; a V-shaped bet transmission wheel is arranged at the middle part of the outer roll; and supporting wheels are arranged at both ends of the outer roll for supporting, supporting wheel axles are installed on the stand, annular end covers are arranged at the both ends of the outer roll for pressing, an outer roll drum is coincided with a silent feeding end and a silent discharging end, and a reversal air-jetting structure is arranged at the clearance of the feeding end to prevent the dust from leaking. The utility model is suitable for rice polishers.
Description
Technical field
The utility model relates to a kind of rice mill, especially relates to a kind of differential double roll rice polisher.
Background technology
Rice mill is mainly by emery wheel and be located at the outer mesh screen of emery wheel and form whitening chamber, brown rice in whitening chamber, carry out pearling owing to collide, roll, whitening pressure and axially carry four factor actings in conjunction after finish.Its major defect is that the grain of rice degree of rolling is little, and stone roller phenomenon broken rice rate height was arranged.
Summary of the invention
The purpose of this utility model is at the existing shortcoming of above-mentioned rice mill, and a kind of reasonable in design, differential double roll rice polisher that result of use is good is provided.
In order to achieve the above object, the utility model is mainly realized by the following technical solutions.The utility model mainly is made up of the frame of differential double roll rice polisher and the arbor of being located on the frame, arbor is provided with interior roller, interior roller is the sand roller of being pieced together by the emery wheel string, the feed end of interior roller is provided with auger conveyor and transition emery wheel, be provided with diagonal bar and spray wind hole between emery wheel, diagonal bar is all parallel with interior roll axis with spray wind hole and to become 62 ° of angles, effect be to continue to produce axial conveying function, and the quantity of diagonal bar is 6,3,2 three kind of specification.Interior roller is provided with annular passage by the belt wheel transmission on the arbor in the interior roller.One of suit has the two rollers of tubular pearling outer roller composition of the speed rotation diamond dust inner surface, different in the same way with interior roller outside interior roller, and the gap between inside and outside roll surface (depositing gas) is identical with conventional rice mill.The middle part of described outer roller is provided with the V-belt drive, and is detachable when dismounting and maintenance outer roller.Both ends are provided with the support roller supporting, and supporting-roller shaft is loaded on the frame, and the two ends of outer roller are provided with the ring-type end cap and compress, outer roller and static feed end and discharge end fit, and the feed end gap is provided with reverse spray wind structure in case flour dust overflow.
As preferably, outer roller supporting of the present utility model can be adopted the rolling ball bearing supporting, and rolling ball bearing is with part tapered sleeve location and adjust, and in order to the dismounting and the maintenance of outer roller, bearing block is provided with core-regulating mechanism, and bearing block is supported on frame with three minor axises.
The utility model compared with prior art has following tangible advantage.(1) rational in infrastructure.The utility model is not arranged chaff in the pearling motion process, rice bran becomes and helps the stone roller agent, during the grain of rice collision cushioning effect is arranged, and relative momentum is little during collision, and minimizing is cracked rice.(2) the V-belt transmission is adopted in outer roller transmission of the present utility model, and is detachable when dismounting and maintenance outer roller.The supporting of outer roller is to adopt support roller supporting or rolling ball bearing supporting, the rolling ball bearing seat has the aligning function, and bearing block is supported on frame with three minor axises, and wherein two minor axises can to outer roller and static support suit place be axial and radial clearance is finely tuned, another minor axis floats, and is fastening after fine setting finishes.(3) be provided with in the roll structure in of the present utility model diagonal bar in order to produce in the whitening chamber, the axial conveying function of rear portion material, spray wind diagonal bar and spray the wind hole deviation degree angle parallel and become 62 ° with interior roll axis.The diagonal bar number is 6,3,2 three kind of specification in order to Control Shaft to transporting velocity.(4) inner chamber spray wind path line, from air-inlet cavity-annular passage-spray wind inclined hole, the ratio that its wind speed was followed successively by 1: 2: 4.2 progressively raises, and the resistance coefficient of wind is little, and blast is stable.
The utility model is applicable to rice mill.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Description of drawings
Accompanying drawing is the two roller whitening chamber cut-away views of the utility model.
