Description

Rice mill

Technical field

The utility model relates to grain processing equipment field, refers to a kind of rice mill especially.

Background technology

The process of rice mill husk rice is exactly removed by the shell of paddy to form chaff and by chaff and process that after shelling, rice is out separated.Its course of work is: first paddy enter after husk rice room contact rice roller through hopper, and the spire on rice roller pushes husk rice room paddy from one end, husk rice room and carries out husk rice, then extrudes rice from the other end.Husk rice room is made up of with the rice roller stretching into screen cloth the screen cloth surrounding tubular, and paddy is constantly knocked and overturns in the high-speed rotation of rice roller on rice roller and screen cloth, produces frictional force and realize shelling in knockout process.

Tradition husk rice axle has and send meter spiral ribs and and husk rice spiral ribs that lead angle larger identical with sending meter Corkscrews direction, and this structure husk rice effect is good not, there is the halfway problem of shelling; Screen cloth is densely covered with the sieve screen apertures of many leakage chaffs, from the original idea of design, wishes that all chaffs are all leaked down by sieve screen apertures, what extrude from the husk rice room other end only has the grain of rice, so just realizes chaff and is separated more thoroughly with the grain of rice.But in fact, although the diameter of chaff is less than the grain of rice, because the husk rice room other end is uncovered structure, also there is small part and extrude together in company with the grain of rice from the end of screen cloth in chaff, add the workload that follow-up chaff is separated with the grain of rice in the motion process of husk rice room.

Utility model content

The utility model provides a kind of rice mill, its technical problem underlying to be solved is: traditional rice mill husk rice effect is bad, the rice ground exists shelling thorough not, and chaff easily along with meter Yi Qi from the end of rice huller screen together out, increase follow-up rice bran mask work amount.

For the deficiencies in the prior art, the utility model provides a kind of rice mill, it comprises casing, feed hopper, rice roller and rice huller screen, there is in described casing the husk rice room of tubular, described husk rice room communicates with described feed hopper, and described feed hopper correspondence is positioned at tubular one end of described husk rice room, the other end of described husk rice room has rice output outlet, what described rice roller was coaxial is arranged in described husk rice room, the surface of described rice roller is provided with feeding screw rib and husk rice spiral rib, one section of described feeding funnel of correspondence at described feeding screw rib place, described rice huller screen is cylinder tubulose, what described rice huller screen was coaxial be set on described rice roller corresponding to being provided with a section of husk rice spiral rib, the hand of spiral of described husk rice spiral rib is contrary with the hand of spiral of described feeding screw rib, and the lead angle of described husk rice spiral rib is greater than the lead angle of the described feeding screw rib of twice.

Be preferable over: one end that described rice huller screen axially corresponds to described rice output outlet is provided with a connection back-up ring, described connection back-up ring is connected to the hole shoulders of described rice output outlet, the endoporus of described connection back-up ring is and goes out metre hole between described rice roller and rice huller screen, and the diameter of bore of described connection back-up ring is less than the diameter of inner pipe of described rice huller screen.

Be preferable over: on described casing, one end of corresponding described rice output outlet is provided with out a meter chamber, the side going out meter chamber described in described rice output outlet correspondence is provided with rice baffle plate, described rice baffle plate be set in described rice roller be plugged in described in go out in meter chamber rotating shaft on, described rotating shaft is arranged with Compress Spring, one end of described Compress Spring supports on described rice baffle plate, the other end support described go out meter chamber madial wall on.

Compared with prior art, the beneficial effects of the utility model are:

One, husk rice spiral rib contrary with the described feeding screw rib hand of spiral on described rice roller is utilized to extend the husk rice time, the paddy constantly entered after the paddy of axially being carried by described feeding screw rib runs into reverse acting spiral and reverse acting spiral extrude, make the husk rice time longer, paddy just can be extruded by rice output outlet one end after being subject to fully grinding and rubbing with the hands under the paddy pressure newly entered;

Two, extend the husk rice time also to rice bran be separated provide in longer time, rice moves to out meter Yi Duan by charging one end of rice roller, and under the obstruction of repercussion spiral, rice bran also to be sieved more thorough;

Three, the meter Yi Duan that goes out by rice huller screen is provided with an aperture and is less than caliber in rice huller screen and goes out metre hole and make the chaff being attached to rice huller screen madial wall be subject to stop can not to be extruded with meter Yi Qi, and then adds out the cleanliness factor of rice.

Detailed description of the invention

Below with reference to accompanying drawing 1 to 4 and preferred embodiment, a kind of rice mill that the utility model proposes specifically is illustrated.

Embodiment one: the utility model provides a kind of rice mill, it comprises casing 1, feed hopper 2, rice roller 3 and rice huller screen 4, there is in described casing 1 the husk rice room 11 of tubular, described husk rice room 11 communicates with described feed hopper 2, and described feed hopper 2 correspondence is positioned at tubular one end of described husk rice room 11, the other end of described husk rice room 11 has rice output outlet 12, what described rice roller 3 was coaxial is arranged in described husk rice room 11, the surface of described rice roller 3 is provided with feeding screw rib 31 and husk rice spiral rib 32, the described feeding funnel 2 of one section of correspondence at described feeding screw rib 31 place, described rice huller screen 4 is in cylinder tubulose, what described rice huller screen 4 was coaxial be set on described rice roller 3 corresponding to being provided with a section of husk rice spiral rib 32, described husk rice room 11 is divided into rice grain pattern road and bran passage by described rice huller screen 4, for going out rice grain pattern road between described rice huller screen 4 and rice roller 3, it is bran passage between rice huller screen 4 and casing 1, the hand of spiral of described husk rice spiral rib 31 is contrary with the hand of spiral of described feeding screw rib 32, and the lead angle of described husk rice spiral rib 32 is greater than the lead angle of the described feeding screw rib 31 of twice.

The present embodiment in the specific implementation, paddy enters described husk rice room 11 from described feeding funnel 2, and under the spiral lift of the feeding screw rib 31 of described rice roller 3 does use, be axially delivered to one section of described husk rice spiral rib 32 place, paddy grinds to rub with the hands and realizes shelling between described husk rice spiral rib 32 and the madial wall of rice huller screen 4, because described husk rice spiral rib 32 is contrary with the hand of spiral of feeding screw rib 31, therefore send into described 32 1 sections, husk rice spiral rib paddy can the follow-up paddy entered with the extruding of reverse acting spiral under be subject to longer time stone roller rub with the hands, and then can Milling degree be promoted, also rice bran sieving time is extended, described in the meter Hui Cong that finally stone roller is de-clean, rice output outlet 12 is extruded.
