Description

Spray wind chaff is pulverized the combination rice mill

The utility model relates to Cereals Processing Machines, particularly sprays the wind chaff and pulverizes the combination rice mill.

Rice mill in the Cereals Processing Machines in the past, have a kind of have can husk rice can carry out the function that chaff is pulverized again, but the rice of the back shelling of must will milling separates earlier with chaff, and then collected chaff is poured in the pulverizer pulverize, and is processed into thin feed.This mechanical structures is combined by devices for husking rice and reducing mechanism, but owing to there is not the rice bran separator, make this machine trouble that seems at work, can not cereal from mill, half chaff separates, chaff is pulverized, disposable finishing continuously flowed out in the rice bran shunting, therefore the grain processing for vast rural area is far from suitable.Present vast rural area universal demand had not only had husk rice but also the rice mill that chaff is pulverized and rice bran separates had been arranged, and pouring what flow out after the cereal on one side is the standard rice, and another side is the required thin bran feed of fowl poultry, requires low price simultaneously, and volume is little in light weight, and is easily practical.The existing husk rice in past has chaff to pulverize the rice mill of function again, and its concrete structure is at underpart pulverizer to be installed, and its transmission device is a belt pulley, also is equipped with on the pulverizer and leads the chaff pipe, and be provided with thin bran outlet, and rice output mouth is connected with devices for husking rice; The top of body is equipped with devices for husking rice, the transmission device that left cover for seat, bearing block, main pulley and drive are formed is installed on the one end main shaft of this device, and the other end is equipped with bearing block, right cover for seat, and housing is arranged at the top of devices for husking rice, at the charging position hopper is housed, is placed on the hopper seat.

The purpose of this utility model provides can husk rice not only can chaff rice separates but also can carry out chaff and pulverize continuously the disposable spray wind chaff of finishing and pulverize the combination rice mill.

The utility model is finished as follows: an end has delivery head on the iron roll in devices for husking rice, and this delivery head continuously advances cereal in the husk rice chamber in the bottom of hopper position; The other end is made hollow shaft, is drilled with several air vents on the axle, and hollow axle end is equipped with the air intake gland, and this hollow space is communicated with intake stack.Iron roll outside cover roller is distributed with the spiral projection on this roller surface, be carved with groove at its position, space, rice huller screen in the roller outer wrapping, and rice huller screen is fixed on the rice sieve support sub-assembly, and the rice sieve support sub-assembly is fixed on the body.The wind wing of inhaling chaff also is installed on the axle in pulverizer, with axle head high pressure positive blower is installed with pulverizer, and has airduct to be connected, lead the chaff pipe and be connected with devices for husking rice with the air intake gland.Constitute spray wind chaff and pulverize the combination rice mill.

Said delivery head is a screw, in the rotation cereal is advanced in the husk rice chamber.Generally being drilled with 20～50 air vents on the hollow shaft makes high-pressure blast outwards spray from the axle center.Be distributed with 1～3 spiral projection on the roller, cereal promoted and making constantly friction between cereal and the rice huller screen, cereal self also rubs and finishes the shelling process.Be carved with 2 grooves at the position, space of spiral projection, high-pressure blast constantly sprayed outward from the axle center set out.Its shape of rice huller screen in the roller outer wrapping and be combined into hexagon, constitute hexagonal reel by two rice huller screens.Said pulverizer is the Weight type pulverizer.Said rice huller screen can also be formed the cylindrical shape rice huller screen by two semicircle tubulars.

The utility model has following advantage: 1, owing to have the high-pressure blast spirt to make husk rice, chaff pulverize, separate disposablely to carry out continuously, rice milling yield height, rice matter are good; 2, owing on the pulverizing arbor air draught wind wing is housed, make the disposable pulverizing of chaff inspiration, make feed; 3, machine volume is little, and is in light weight, cheap, and compact conformation is easy to operate, but not only fixed operation but also can be contained in and carry out mobile operational process on the handcart, and especially promote in mountain area or animal husbandry area to be well suited for vast rural area.

Further describe embodiment below in conjunction with accompanying drawing.

Fig. 1 is a general assembly drawing of the present utility model.

Fig. 2 is the devices for husking rice partial sectional view.

Fig. 3 is the A-A cutaway view of Fig. 2.

With reference to Fig. 1 Fig. 2 Fig. 3, spray wind chaff is pulverized the combination rice mill, is to be formed by the further improvement that former No. 2 rice mills is added the pulverizer combination.Original structure is equipped with pulverizer (11) in body (10) bottom, and its transmission device is belt pulley (9), leads chaff pipe (12) and thin bran outlet on the pulverizer (11), and rice output mouth (13) communicates with devices for husking rice, and the Mi Congqi that grinds good is flowed out; The top of body (10) is equipped with devices for husking rice, and the transmission device that left cover for seat (4), bearing block (5) main pulley (6) and drive (7) are formed is installed on the end main shaft (21) of this device, and the other end is equipped with bearing block (16), right cover for seat (17).Housing (3) is arranged at the top of devices for husking rice, and hopper (1) is installed at the charging position, is placed on the hopper seat (2).

Devices for husking rice is that the last end of iron roll (15) has delivery head (20), and in the bottom of hopper (1) position, the other end is made hollow shaft, is drilled with 20～50 air vents on the axle, and hollow axle end is equipped with air intake gland (14).Iron roll (15) outside is with roller (22), is distributed with 1～3 of spiral projection on its surface, is used to promote the friction between cereal and the rice huller screen (18).Be carved with 2 grooves at the position, space of spiral projection, its high-pressure blast is sprayed outward from the axle center to be set out, on the one hand be chaff ejection outward from the rice huller screen (18), the aspect is to speed up for heat in the rice milling process is distributed in addition, helps improving the grade and the quality of husk rice.Its shape of rice huller screen (18) in roller (22) outer wrapping and be combined into hexagon, constitute the hexagonal rice huller screen, also can form the cylindrical shape rice huller screen by two semicircular cylinder shapes by two rice huller screens.Delivery head (20) is a screw, makes cereal advance the husk rice chamber.Rice huller screen (18) is fixed on the rice sieve support sub-assembly (19), and rice sieve support sub-assembly (19) is fixed on the body (10).

The wind wing of inhaling chaff is housed in pulverizer (11), with the chaff of rice milling process by leading chaff pipe (12) inspiration pulverizing chamber.With axle head high pressure positive blower (18) is installed with pulverizer (11), and has airduct to be connected, make in the hollow shaft of high-pressure blast spirt husk rice constantly chamber with air intake gland (14).Pulverizer (11) is provided with leads chaff pipe (12) and thin bran outlet, lead chaff pipe (12) and be connected with devices for husking rice, under the effect of the wind wing constantly in the chaff inspiration pulverizer (11).Pulverizer (11) is the Weight type pulverizer, generally is such structure.

Grain advances and utilizes the effect of iron roll (15) and rice huller screen (18) through delivery head (2), make paddy material shelling pearling, under high pressure spray wind action, brown rice separates voluntarily with chaff, the thin chaff of chaff is by discharging in the sieve film perforation, suck pulverizing chamber by pulverizer (11) suction and pulverize and make standard feed, outside the discharge machine, standard meter is flowed out by rice output mouth (13).Have the rice milling yield height, rice matter good, the grain of rice is complete, the chaff disposable powder can be broken into feed.
