Abstract

The utility model relates to a miniature rice husking and sieving combined rice milling machine, a rice husking machine mainly composed of a feeding roller and two side-by-side husking rubber rollers is installed under the hopper, and the rice husking machine is installed on the rough On the husk separator, inside the rough husk separator there is a brown rice channel leading to the whitening machine, a special outlet for diseased grains and immature grains, and a chaff channel. There is a high-pressure fan, the outlet of which is connected to the sieving machine with a rubber hose and communicates with the cavity of the main shaft, and the polishing rice roller has an air outlet that communicates with the cavity of the main shaft, and the sieving machine is surrounded by a rice sieve, and its front end has a white rice outlet . The utility model is characterized by small size and low price, can process high-quality rice and produce high-quality rice, the bran powder can be screened cleanly, and the rice quality is good, which is especially suitable for rural families.

Description

A kind of miniature combined rice hulling and sieving mill

The utility model relates to a kind of processing of paddy processing equipment, particularly grain quality rice.

Existing domestic miniature rice mill is solid polishing rice roller made of iron, disposable paddy is ground into rice, and it is little, simple in structure to have a volume, advantages such as low cost of manufacture, but following weak point is arranged:

1, disposablely grind rice, rice matter is rough, and broken rice rate is up to 42% and poor, and rice milling yield is low.

2, crudy is poor, the dust content height, and a large amount of rice brans flows into packaging bag or container with rice from outlet.

3, because the grain quality rice particle is elongated, therefore existing domestic miniature rice mill can't adapt to, let alone has processed superior rice.

Though existing large-scale rice huller paddy husk rice unit mahine can adapt to the processing of grain quality rice, can produce superior rice, exist bulkyly, defective such as cost an arm and a leg is not suitable for rural households and uses.

The purpose of this utility model provides a kind of miniature combined rice hulling and sieving mill, accomplishes that volume is little, price is low, and energy processing high grade rice and production superior rice are fit to rural households and use.

The purpose of this utility model is achieved in that and changes existing large-scale rice huller paddy husk rice unit mahine into single phase poaer supply by the use three phase mains, cancellation lifting device and simplification screening plant, and it is white mechanical with sieve to keep the hulling machine tool.We can say also, existing domestic miniature rice mill improved that below its paddy bucket hulling machine tool and rough paddy separator are installed, rough paddy separator is positioned at the top of the white machinery of original sieve.When paddy enters the hulling machine tool by the paddy bucket, at first stir paddy it is evenly shelled by the shelling rubber roll, flow to rough paddy separator then, under the wind-force effect of big blower fan, blow out husk by feeding roller, wherein infected seed and prematurity grain are produced by special use and are flowed out, and brown rice then flows to the white machinery of sieve.In addition, on the main shaft of the white machinery of sieve cavity is arranged, there is air outlet to communicate on the polishing rice roller of suit on the main shaft with spindle cavity, spindle cavity communicates with high pressure positive blower, therefore, brown rice through the screw propulsion roller advance, white, and under the high-pressure blast effect of high pressure positive blower, blow out the chaff powder, rice flows out through the rice outlet.

Compared with the prior art, the utility model has following characteristics:

1, just the inflow sieve was white mechanical after paddy was handled owing to paddy is hulled in advance, and therefore energy processing high grade rice is produced superior rice.

2,, therefore be fit to very much rural households and use because volume is little, and low cost of manufacture adopts single phase poaer supply again.

3, because the main shaft of the white machinery of sieve has cavity, can from inside to outside blow out high-pressure blast, so the choosing of chaff dressing sieve is clean, rice matter is good.

Describe concrete structure of the present utility model and operation principle in detail below in conjunction with drawings and Examples.

Fig. 1 is miniature combined rice hulling and sieving mill the first half front view.

Fig. 2 is miniature combined rice hulling and sieving mill the latter half front view.

Fig. 3 is miniature combined rice hulling and sieving mill right view.

As shown in the figure, by a left side, right wallboard 1 and 2 frame lower that constitute are equipped with the white machinery 3 of sieve, be set with screw propulsion roller 5 and polishing rice roller 6 on the main shaft 4 of the white machinery 3 of sieve, its difference is that paddy 7 belows of struggling against are equipped with main by feeding roller 8 and two hulling machine tools 10 that shelling rubber roll 9 side by side constitutes, hulling machine tool 10 is installed on the rough shell separator 11 that is positioned at upper rack, the brown rice passage 12 that leads to the white machinery 3 of sieve is arranged in the rough shell separator 11, special-purpose outlet 13 of infected seed and prematurity grain and husk passage 14, big blower fan 15 is equipped with in husk passage 14 exits, rough shell separator 11 outer middle side parts are equipped with high pressure positive blower 16, there is sebific duct 17 to be connected to the white machinery 3 of sieve in its outlet and communicates with the cavity of main shaft 4, on the polishing rice roller 6 air outlet 18 that communicates with main shaft 4 cavitys is arranged, be surrounded with rice huller screen 19 around the white machinery 3 of sieve, its front end has rice outlet 20.In addition, motor on big blower fan 15 and the high pressure positive blower 16 is a monophase machine, on 15 of the big blower fans drive pulley is housed, on main shaft 4 and all beaming roller driven pulley is housed, by belt by the motor drives main shaft on the big blower fan 15 4 and all beaming roller rotations.

Operation principle is as follows: paddy falls from paddy bucket 7, at first stirs through feeding roller 8, is pushed into differential shelling between two shelling rubber rolls 9, falls into then in the rough shell separator 11.Under the wind-force effect of big blower fan 15, husk is blown through husk passage 14, infected seed flows out through special use outlet 13 with the ripe grain of rice, brown rice then enters white mechanical 3 brown rice of sieve under the propelling of screw propulsion roller 5 through brown rice passage 12, and is white through polishing rice roller 6 polishing sieves, meanwhile, high-pressure blast from high pressure positive blower 16 enters main shaft 4 cavitys through sebific duct 17, blown out by air outlet 13, the chaff powder is blown afloat and sift out from rice huller screen 19, remaining high-quality rice flows into packaging bag or container from rice outlet 20.
