Abstract

The invention relates to a rice milling machine comprising a feeding control assembly and a whitening chamber assembly. The feeding control assembly comprises a feeding adjusting door. The whitening chamber assembly comprises a sand roller comprising a sand core and an iron core positioned inside the sand core. The sand core and the iron core are detachably connected. The sand core is divided into three parts which are a first sand core section, a second sand core section, and a third sand core section. Each section of sand core adopts a same structure comprising a sand core body, and a front flange and a back flange respectively arranged on two ends of the sand core body. The front flange and the back flange are connected through bolts. Key slots are arranged on both of the front flange and the back flange. According to the invention, the sand core is divided into three parts; the first sand core section adopts a deep spiral groove, such that delivery output is ensured; the second sand core section adopts a medium spiral groove, such that milling effect is ensured; and the third sand core section adopts a plurality of oblique straight grooves, such that milling precision and rice output are controlled. The sand core and the iron core are separately manufactured and are assembled by using bolts and nuts. Therefore, when the sand core is worn, only the sand core on the outer part is replaced.

Description

A kind of rice mill

Technical field

The present invention relates to a kind of rice mill, be 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 the 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.This traditional making and the shortcoming of design be, because the sand roller is wear-out part, general service life is also with regard to 2-3 month, the tail end of sand roller particularly, and because outlet pressure is larger, especially easily wearing and tearing, cause the precision of husk rice to guarantee; Simultaneously, because iron core and sand roller are sintered together, so change iron core afterwards, also can't utilize, thereby cause great waste.Poor to the control accuracy of inlet amount in prior art simultaneously, affected to a certain extent rice milling yield and the quality that goes out rice.

Summary of the invention

The present invention is directed to the deficiency in the above-mentioned background technology, propose that a kind of sand roller is convenient to change, can essence grinds, can accurately control the rice mill of inlet amount simultaneously.

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

Preferably, the diameter of the diameter of described the first core section employing sand grains>second core section employing sand grains>the 3rd core section adopts 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 >=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 the 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 invention has the beneficial effects as follows: 1. the sand roller is divided into to three parts, the first core section adopts deep spiral groove to guarantee to carry output, and 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 the 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 for current meter factory, processing, the characteristics that grain variety mixes, the 3rd core Duan Weijing grinds section, can both reach the purpose of controlling out Mi Jingdu and output according to the multiple combination pattern of different materials and different grooveds, can also enlarge the scope of application of rice mill.

The specific embodiment

As shown in Figure 1, the sand rice mill generally is comprised of charging control part dress I, whitening chamber section dress II, blower fan section dress III, framework portion dress IV, motor section dress V, refining bucket section dress VI six parts.Charging control part dress: parts such as control box, feed hopper, feed hopper base, Flow-rate adjustment doors, consist of, hopper is fixed on the frame charging aperture.Whitening chamber section 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 section 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.The motor section dress: by motor, the compositions such as electric baseboard, motor support base.Refining bucket section 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 Fig. 2, to shown in Figure 5, removably connect between the core of sand roller of the present invention and iron core, 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 core adopts identical structure, that is: the core body 4, are respectively equipped with forward flange 5 and rear flange 6 at core body 4 two ends, and forward flange 5 is connected by bolt 7 with rear flange 6, is equipped with keyway 8 on forward flange 5 and rear flange 6.

The first core section 1 adopts the 24-30# coarse sand, spiral groove depth 12-15mm, helical pitch 300-360mm, the conveying output of assurance rice machine.The second core section 2 adopts 30-36# medium size diamond dust, spiral groove depth 8-12mm, and helical pitch 300-360mm, be meter major part of machine pearling, guarantees milling efficiency.And the second core section can be provided with a plurality of the second core sections as required.The 3rd core section 3 adopts the 36-46# fine sand, according to the difference of Milling degree and grain variety, adopts the oblique straight trough of different materials, varying number and angle, controls and mills precision and go out a meter output.A complete set of core sand grains arrangement from coarse to fine from the beginning to the end is 24#-46#, has guaranteed in the pearling process, in the effective length of roller, realizes opening the effect that rough, pearling, essence are ground.
