Description

A kind of rice mill

Technical field

The utility model relates to a kind of rice mill, is applicable to that opening of the plurality of cereals cereal such as rice, glutinous rice, Chinese sorghum, seed of Job's tears is rough, pearling, essence grind the rice mill of processing.

Background technology

Roller, for rice mill, is one of parts of core the most.The roller of existing rice mill mainly be take sand roller as main, and the production method of sand roller is by outside diamond dust and inner integral sintered the forming of cast-iron core.The shortcoming of this traditional making and design is, because sand roller is wear-out part, general service life, particularly the tail end of sand roller, because outlet pressure is larger, especially easily wore and tore, and causes the precision of husk rice to guarantee also with regard to 2-3 month; Simultaneously, because iron core and sand roller are sintered together, so change iron core afterwards, also cannot utilize, thereby cause great waste.Simultaneously poor to the control accuracy of inlet amount in prior art, affected to a certain extent rice milling yield and the quality that goes out rice.

Utility model content

The utility model is for the deficiency in above-mentioned background technology, proposes that a kind of sand roller is convenient to change, can essence grinds, and can accurately control the rice mill of inlet amount simultaneously.

The technical solution adopted in the utility model is: a kind of rice mill, comprise charging control part dress and whitening chamber portion dress, described charging control part dress comprises charging adjustment doors, described whitening chamber portion dress comprises sand roller, described sand roller comprises core and iron core, and described iron core is positioned at core inside, it is characterized in that: between described core and iron core, removably connect, described core is divided into three parts, i.e. the first core section, the second core section and the 3rd core section; Every section of core adopts identical structure, that is: core body, is respectively equipped with forward flange and rear flange at core body two ends, and forward flange and rear flange are bolted, and on forward flange and rear flange, are equipped with keyway.

Preferably, described the first core section adopts the diameter > second core section of sand grains to adopt diameter > the 3rd core section of sand grains to adopt the diameter of sand grains.

Preferably, between described the first core section and the second core section, between the second core section and the 3rd core section, all by flange, connect.

Preferably, described the first core section and the second core section are provided with helicla flute, and the first core section spiral fluted degree of depth >=the second spiral fluted degree of depth.

Preferably, the 3rd core section is provided with oblique straight trough.

Preferably, charging adjustment doors below is fixedly connected with gear bar, and charging control part dress also comprises adjusting gear, described gear and the engagement of gear bar; Adjusting gear is connected with adjusting rod, and it is outside that described adjusting rod one end is positioned at charging control part dress.

The beneficial effects of the utility model are: sand roller is divided into three parts 1., the first core section adopts deep spiral groove to guarantee to carry output, the second core section adopts medium helicla flute to guarantee milling efficiency, and the 3rd core section adopts the oblique straight trough of multiple tracks to control and mills precision and go out a meter output; 2. the core of sand roller and iron core are made separately, then by screw rod and nut, be assembled together, thus after core wearing and tearing, only need the outside core of replacing, and iron core can retain and reuses, and greatly cuts the waste; 3. in processing for current meter of factory, the feature that grain variety mixes, the 3rd core Duan Weijing grinds section, can both reach the object of controlling out meter Jing Du and output according to the multiple combination pattern of different materials and different grooveds, can also expand the scope of application of rice mill.

The specific embodiment

As shown in Figure 1, sand rice mill is generally comprised of charging control part dress I, whitening chamber portion dress II, blower fan portion dress III, framework portion dress IV, motor portion dress V, refining bucket portion dress VI six parts.Charging control part dress: be comprised of parts such as control box, feed hopper, feed hopper base, Flow-rate adjustment doors, hopper is fixed on frame charging aperture.Whitening chamber portion dress: grind the parts such as material toggling roller, main shaft, spiral head, feed end bearing block, discharge end bearing block, rice huller screen, rice huller screen press strip by main sand roller, essence and form.Blower fan portion dress: the compositions such as fan supporter, Fan casing, impeller, blower motor.Frame: mainly formed by frame, upper air regulating board, side door, bran-collecting bucket, protective cover etc.Motor portion dress: by motor, the compositions such as electric baseboard, motor support base.Refining bucket portion dress: the compositions such as refining bucket, cool rice airduct, sampling plate.These are conventional design or are prior art in the design of rice mill, therefore do not do detailed tired stating at this.

As shown in Figures 2 to 5, between the core of the utility model sand roller and iron core, removably connect, core is divided into three parts, i.e. the first core section 1, the second core section 2 and the 3rd core section 3; Every section of core adopts identical structure, that is: core body 4, at core body 4 two ends, is respectively equipped with forward flange 5 and rear flange 6, and forward flange 5 is connected by bolt 7 with rear flange 6, on forward flange 5 and rear flange 6, is equipped with keyway 8.
