Abstract

A one time clean rice mill essentially comprises a feed bearing shaft, a discharging bearing shaft, a rice frame, a roller, a discharging baffle, a spring and a air-blower vane. Adopting a active rice machine box cover is convenient for adjusting the rice cutter gap, eliminating the stem and replacing the rice sieving screen. Adopting the discharging location set to adjust the rice discharging gap means that the spring has adjusted the rice discharging gap. Adopting polytropic bran leakage has improved the bran leakage efficiency. Adopting the coaxial belt blower makes the whole structure to be more impact which has saved the energy source and improved the efficiency of choosing the rice.

Description

Once clean paddy rice mill

The utility model relates to the paddy processing equipment, particularly a kind of once clean paddy rice mill.

At present electronic rice bran seperator is adopted in the rural area, and it is that motor is used as power, and ad hocly has blower fan to make wind regime, its complex structure, and maintenance difficult, and the shelling rate is not high.The patent No. be ZL97205678.5 patent disclosure a kind of " multi-functional rice bran seperator " its feature be to integrate power source, wind regime, workpiece is combined by left-handed rib muscle monomer roller and working shaft, it is different with structure of the present utility model.

The purpose of this utility model provides a kind of once clean paddy rice mill of novel structure.

The purpose of this utility model is achieved through the following technical solutions.

A kind of once clean paddy rice mill, in rice frame upper fixed a meter machine box is arranged, be provided with bran output bucket in the middle of it, left at rice machine box is provided with belt pulley, feed hopper, the feed shaft bearing, it is right-hand to be discharge bucket successively, discharging bearing block and Fan casing, the upper left feed shaft bearing of rice frame upper fixed has feed hopper, be provided with a meter arbor in feed shaft bearing and the discharging bearing block, this meter arbor extends to the right, and at its terminal fan blade that connects, the rice arbor is with cylinder outward, the first half of cylinder is the screw propulsion angle, the first half of rice machine box is a removable cover, by the pin of living, fastening bolt is fixed, being provided with circle-shaped outside the cylinder in rice machine box fixes, the rice cutter of following rice huller screen and stationary adjustable, in the right-hand discharge bucket of rice machine box, be fixed with the discharging opening plate washer by the pressure regulation positioning sleeve on the rice arbor, pressure spring and look nut, the discharging opening of annular is located at adjustable discharging opening plate washer front, below Fan casing, be fixed with link to each other with discharge bucket blow formula multi-stage separation case, the below of separator box is a slanted screen.

The utility model has the advantages that: 1. adopt feed hopper to be fixed on the feed shaft bearing, the feed hopper that changes general rice machine is fixed on meter machine and covers, make the rice machine cover opening and closing easy, be convenient to adjust a meter cutter gap, be convenient to remove the convenience of stopping up the thorax material in meter machine box and changing rice huller screen; 2. adopt the stable rice of two end axles bearing arbor, make the bearing good stability, because discharging positioning sleeve adjustable clearance has prevented that effectively the rice slag from entering bearing; Discharging opening is an annular, has reduced the resistance of rice, and broken rice rate is low, has improved rice output; Spring has adjusted a meter pressure, can adjust the fair and clear degree of rice; 3. adopt upper and lower rice huller screen, the tripartite chaff that leaks in the both sides of rice machine box and bottom surface, and general rice machine has only the bottom surface to leak chaff, thus increased leakage chaff area, leak the chaff better effects if; 4. adopt the design of coaxial drive blower fan, and use blower fan to compare separately, cost reduces, energy-saving effect is good, and the use of blowing formula multi-stage separation case has volume little, and retractable advantage more can improve the selection by winnowing effect, makes selection by winnowing of paddy clean.Being used as power with 1.1 watts of home motors is example, and when not being with blower fan, the shelling rate is more than 240KG/ hour, and (general rice machine with under the constant power, shelling rate 150KG/ hour) improves shelling rate 40%; Once clean shelling rate 200KG/ hour (it is clean that generally a rice machine needs the above shelling ability of secondary) improves shelling rate 60% during the band blower fan; 5. the angle at preferred screw propulsion angle shortens drum length, improves drum rotation speed, improves work efficiency.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is an A-A cutaway view of the present utility model.

Be further described this reality is novel according to accompanying drawing below.

As shown in Figure 1, in rice frame 17 upper fixed a meter machine box 23 is arranged, be provided with bran output bucket 16 in the middle of it, be provided with belt pulley 4 at rice machine box 23 lefts, feed shaft bearing 1, the upper fixed of feed shaft bearing 1 has feed hopper 5, be provided with meter arbor 3 in the feed shaft bearing 1 of rice machine box about 6 and the discharging bearing block 12, this meter arbor 3 extends to the right, and at its terminal fan blade 14 that connects, the rice arbor 3 outer cylinders 2 that are with, the first half of cylinder 2 is provided with screw propulsion angle 25, and this angle is 240 °, and it is different with general rice machine angle, improve the paddy fltting speed, the first half of rice machine box 23 is a removable cover 6, by the pin 19 of living, fastening bolt 20 is fixing, is provided with on the circumferential frame fixes in cylinder 2 peripheries of rice machine box 23, the rice cutter 21 in following rice huller screen 22 and stationary adjustable gap; In right-hand discharge bucket 15 of rice machine box 23, be fixed with pressure spring 9, look nut 10 and discharging opening plate washer 8 by the pressure regulation positioning sleeve 11 on the rice arbor 3, the discharging opening 7 of annular is located at adjustable discharging opening plate washer 8 fronts, it is little that the annular discharging opening of anode goes out meter resistance, improved rice output; Below Fan casing 13, be fixed with link to each other with discharge bucket 15 blow formula multi-stage separation case 18, be slanted screen 24 below separator box 18.Its operation principle is: the motor as power is started working, pulley concial disk 4 drives cylinder 2 rotations, make the paddy that enters from feed hopper 5 do circumference and axially-movable, feed hopper 5 can be regulated the suitable paddy that advances and measure, under the extruding that cylinder 2 rotations advance, paddy passes through in the gap of rice cutter 21, and in the intensive hole of rice huller screen 22 with the rice hulls fragmentation, separate, rice bran is by the rice huller screen 22 holes chaff discharging port 16 that bleeds, and rice and a spot of chaff shell are from discharging opening 7 outflows of anode annular, enter the multistage formula separator box 23 that blows through discharge bucket 15, the air-flow that coaxial blower fan 14 produces is with rice, chaff separates, rice with tiny crack rice to separate once more through slanted screen 24 obtain fair and clear rice.In order to prevent that the rice bran slag from axially flowing into bearing, regulating pressure regulation positioning sleeve 11 is adjusting nut 10 and spring 9, can regulate the minimum clearance of discharging opening plate washer 8, even there is the chaff slag of minute quantity to flow to bearing, on bearing block, be provided with poroid being pickled with grains or in wine, can guarantee that also a meter machine normally moves.
