Abstract

The utility model relates to a double-roller rice mill, which belongs to the technical field of grain processing machinery. The rice mill comprises a rice feeding hopper placed above a machine frame, a blower mounted at the lower part of the machine frame and a bran storage hopper, wherein the machine frame is equipped with an upper rice milling roller and a lower rice milling roller which are driven by a driving device; the lower part of the rice feeding hopper faces to one end of the upper rice milling roller, and the other end thereof is positioned above a feed port; and the lower end of the rice feeding hopper faces to one end of the lower rice milling roller, and a rice discharge mouth is mounted the other end thereof. When the rice mill is in use, rice to be rolled is fed into the rice mill, rolled by the upper rice milling roller for the first time, then drops into the lower rice milling roller to be rolled for second time, and finally is output; and as twice rolling can be achieved at one time on one machine, the work efficiency is remarkably improved, energy is saved and working area is reduced.

Description

Double roll rice polisher

Technical field

The utility model relates to a kind of rice mill, and especially a kind of double roll rice polisher belongs to the Cereals Processing Machines technical field.

Background technology

Rice mill is a development in recent years rice finish machining equipment rapidly.Applicant applied for once that the patent No. was called " iron roll strong punkah rice mill ", the patent No. are called " two air channels rice mill " for the 200820033646.X name Chinese patent for the 01263106.X name.Wherein two air channels rice mill comprises and is placed in advancing Mi Dou, being supported on upper rack and passing through the horizontal hollow spindle that holds the chaff chamber, be installed in the blower fan of frame lower and deposit the chaff bucket of frame top; One end of described main shaft communicates with the air outlet of blower fan, and the helical feed head that is connected to advance Mi Dou and holds the chaff chamber is equipped with at the middle part; It is characterized in that: fixed in position roller shape screen frame in the described appearance chaff chamber; Described screen frame mainly is made of one group of horizontal spoke, the sieve sheet and the cyclic reinforcing rib of fixed interval outside spoke that are connected between the adjacent level spoke, wherein holds the iron roll that is fixed on the main shaft.

Above-mentioned prior art all has only a rice milling roller, in order to guarantee the husk rice quality, usually needs two machine secondaries to roll processing, and is not only time-consuming, and wastes energy.

The utility model content

The purpose of this utility model is: the double roll rice polisher that at the shortcoming that above-mentioned existing rice mill exists, proposes a kind ofly can disposablely to finish slightly, essence rolls processing.

In order to reach above purpose, double roll rice polisher of the present utility model comprises and is placed in advancing Mi Dou, be installed in the blower fan of frame lower and deposit the chaff bucket of frame top; Wherein, described frame is equipped with upper and lower two rice milling rollers that transmission device drives; The described below of advancing Mi Dou is facing to the end at last rice milling roller, the described other end at last rice milling roller be positioned at charging aperture above, the lower end of described feed hopper is facing at an end of rice milling roller down, describedly at the other end that descends rice milling roller rice output mouth is housed.

During use, will wait to grind rice and add rice mill, earlier through roll the rice milling roller under falling within afterwards, output after second road rolls in first road of last rice milling roller from advancing the rice bucket.Because two roads roll on a machine once property and finish, so work efficiency significantly improves, and saved the energy and work-yard.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of an embodiment of the utility model.

The corresponding parts name of each sequence number is called among the figure: air outlet bearing cap 1, self-aligning bearing 2, oil sealing 3, outlet bearing block 4, outlet bracing ring 5, semicircle rice huller screen 6, sand roller 7, micro-adjusting mechanism 8, charging seat 9, charging takes over 10, feed hopper 11, spiral propeller 12, import lining ring 13, imported bearing seat 14, bearing 15, the import supporting covers 16, race ring 17, oil sealing 18, oil sealing 19, the sand roller is got rid of cap 20, iron roll outlet bearing block 21, outlet lining ring 22, bearing 23, iron roll is got rid of cap 24, oil sealing 25, iron roll race ring 26, iron roll 27, hexagonal reel 28, screen frame 29, iron roll spiral propeller 30, oil sealing 31, bearing 32, iron roll imported bearing seat 33, imported bearing flap 34, upper box 35, iron roll charging aperture 36, sand roller belt pulley 37, sand roller main shaft 38, iron roll belt pulley 39, iron roll main shaft 40, regulating wheel 41, regulating wheel gland 42, bearing 43, bearing chuck 44, tension wheel shaft 45, tensioning wheel seat 46, blower fan belt pulley 47, oil sealing 48, fan bearing flap 49, protective cover 50, bearing 51, blower fan axle 52, blower fan holder 53, bearing block inner cap 54, draught fan impeller 55, Fan casing 56, lower box 57, deposit chaff bucket 58, rice output mouth 59.

The specific embodiment

Embodiment one

The double roll rice polisher of present embodiment settles rice bucket 11, bottom draught fan impeller 55 to be installed and to deposit chaff bucket 58 as shown in Figure 1 above the housing frame.Upper and lower two rice milling rollers that are supported on bearings at both ends and drive by belt transmission are housed in the frame.Last for being included in the sand roller 7 semicircle rice huller screen 6 in, under be the iron roll 27 that is included in the hexagonal reel 28.A below of advancing rice bucket 11 is facing at last sand roller 7 one ends, and the other end of sand roller 7 is positioned at the top of charging aperture 36, the lower end of this feed hopper facing under iron roll 27 1 ends, the other end of iron roll 27 is equipped with rice output mouth 59.

During use, will wait to grind rice and add rice mill from advancing the rice bucket, through rolling in the first road roughing of last sand roller, the iron roll under feed hopper falls within after the iron roll second road fine finishining rolls, is exported from rice output mouth afterwards earlier.Two roads roll chaff skin in the process respectively through the screening of semicircle sieve and hexagonal reel, fall into to deposit the chaff bucket bottom the housing frame.

Obviously, the double roll rice polisher compact conformation of present embodiment is saved the space, and is had power savings.Because two roads roll on a machine once property and finish continuously, therefore avoided transfering process, operating efficiency significantly improves.In addition, adopt dissimilar rolling bodies up and down, can rationally be provided with and roll the gap, thick fine finishining is coordinated mutually, thereby effectively reduced broken rice rate.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
