Frame husk rice house also comprises the feed hopper of establishing on the frame 208; With connect feed mechanism (employing spiral propeller 203 in the present embodiment) on the each other corresponding main shaft 202 in feed hopper 208 positions; Connect rice milling roller on the main shaft 202, the rice huller screen assembly of establishing in the frame, rice huller screen assembly comprise the lower and upper cross-member 104 that connects on the frame; Be connected with rice huller screen carriage 105 on the lower and upper cross-member 104, connect on the rice huller screen carriage 105 and support rice huller screen 106; Rice milling roller adopts the sand roller 204 of tubulose; Sand roller 204 surfaces have helicla flute and have air vent to pass sand roller tube wall.Main shaft 202 connects two bearing ribs 205,207 at interval, and bearing rib 205,207 is connected with sand roller 204.Space between main shaft 202 and sand roller 204 inwalls constitutes air chamber.
The spray wind section of main shaft 202 is located at feed side.
The air draught section of main shaft 202 is located at exit side.
The end perforate 210 of main shaft 202 feed sides is connected UNICOM with spray wind blower fan 103.
The spray wind section of main shaft 202 is provided with spray wind hole, and the spray wind hole on the main shaft spray wind section is provided with multirow vertically, and the spray wind hole of present embodiment is provided with triplex row; Promptly distribute along circumference 120 degree; Like Fig. 2, shown in 3, the spray wind hole circle heart on the adjacent lines is not in same periphery, and spray wind hole shifts to install; Spray wind as shown in Figure 3 hole 301,302 is in same periphery in the present embodiment, and spray wind hole 303 is arranged with 301,302 dislocation of spray wind hole; Spray wind section is divided into spray wind leading portion and spray wind stage casing, and promptly the main shaft on bearing rib 205 right sides is spray wind leading portion, and the main shaft in bearing rib 205 left sides is spray wind back segment.The gross area in spray wind hole is greater than the gross area in spray wind hole on the spray wind leading portion on the main shaft wall in spray wind stage casing.
The air draught section of main shaft 202 is provided with wind inlet, and main shaft 202 air draught sections (being that the air draught section is the main shaft rear) are on the right side of bearing rib 207.Wind inlet comprises the wind inlet 320 of the main shaft 202 air draught sections that the wind inlet 310 of 204 times correspondences of sand roller is outer with stretching out frame.Present embodiment wind inlet 310 is provided with triplex row, promptly distributes along circumference 120 degree, realizes the dislocation layout.
Like Fig. 4, shown in 5, wind inlet 320 is provided with four lines vertically, and the four lines wind inlet is divided into two groups, and two wind inlets of each group are in diametric(al) setting (symmetry); Shift to install between two groups.
As shown in Figure 1, main shaft exit side bracing frame 111 supports through bearing 112 and main shaft 202 air draught sections.Bracing frame is provided with air intake inlet scoop 113, and air intake inlet scoop 113 communicates with wind inlet 320 on the main shaft wall; 113 places, air intake inlet scoop on the bracing frame establish air intake inlet scoop aperture adjustable plate 108.Aperture adjustable plate 108 adopts the shutter board of circular arc.The bearing location of being connected with of main shaft exit side bracing frame 111 cover 114, and bearing is located and covered 114 tegmental wall and offer air vent 115, and air vent 115 communicates with main shaft exit side end perforate 211.
The gusset that sand roller 204 is connected with main shaft at the sand roll shaft to the center, with sand roller inner chamber be isolated into preceding, in, three air chambers of tail.Be respectively leading portion malleation air chamber, stage casing malleation air chamber and tail end negative pressure chamber.
In rice mill when work: circular rice huller screen inwall and sand roller circumferential outer surface be apart from being called " depositing gas " for δ, and the chamber that is formed vertically by radially " deposit gas " δ and rice huller screen inwall and sand roller outer surface becomes " whitening chamber "; Brown rice is got into by charging aperture; Send into " whitening chamber " along circumference and axially-movable through spiral propeller 203; The grain of rice contacts with the sand roller to grind and cuts the chaff cortex in " whitening chamber ", and the grain of rice grinds in spiral propeller 203 promotion lower edge journeys to be cut, through closing outside the wind discharging opening 109 eliminating machines; Inhale outside under the effect of chaff wind net, the chaff powder that stone roller removes is discharged " whitening chamber " through rice huller screen 106 and is inhaled chaff wind net through inhaling 110 suctions of chaff buckets.
Usually rice mill is joined suction chaff wind net outward provides the air draught more than the blast 1500Pa to rice mill, inserts and inhales chaff bucket 110.Main shaft two ends air intake, an end are forced draft, and the other end is the negative pressure air draught; Be provided with separated wind locking head 206 in the main shaft axle endoporus is divided into two different pressure an actor's rendering of an operatic tune of malleation and negative pressure, the space that sand roller inwall and spindle outer wall constitute is called " air chamber ", and the malleation wind regime is provided by spray wind blower fan 103; Get into the main shaft axis hole from feed end; Send into head section, stage casing " air chamber " through the main shaft radial hole along journey, form head section malleation air chamber, stage casing malleation air chamber, spray into whitening chamber; The other end of main shaft communicates with air; Under the suction function that the exogenous wind net provides, suck the rear whitening chamber through main shaft axis hole, rear negative pressure " air chamber "; Under the effect of exogenous wind net negative pressure air draught; When the malleation wind of one end and the negative pressure wind of the other end get into whitening chamber through sand roller air vent, preceding, in, the windage of rear is autobalance (head section resistance h
Head=stage casing resistance h
In=rear resistance h
Tail).Because the rear whitening chamber communicates with air, the discharging bearing block is provided with air inlet through hollow shaft has increased incoming air area, and radially air intake has shortened the blast pipe segment length and reduced the air intake resistance, makes negative pressure air intake pipeline section resistance little; And stage casing and head section blast pipe segment length, the air intake resistance is big, adopts the supercharging air-supply to overcome the air intake resistance, and whitening chamber head section resistance, stage casing resistance and rear resistance are equated.
