Description

Rice processing chaff device

Technical Field

The utility model belongs to the technical field of the rice processing, concretely relates to rice processing chaff device.

Background

With the improvement of the quality of life, the requirements of people on rice are higher and higher, the production quantity of the rice is increased, the husks and the peels, the seed coats, the endosperm, the paste layers and the embryos which account for about 10 percent of the total weight of the rice need to be removed in the process of processing the rice into fine rice, the impurities which need to be removed can be processed into rice bran, the rice bran can only be used for feed, so a small amount of rice husks and a certain amount of dust and microorganisms can be mixed in the rice processing process, if the rice bran sieving treatment is not carried out, the eating is greatly influenced, and the rice bran in the rice needs to be removed by a bran sieving device so as to meet the taste requirements of people. In the prior art, the problem of low bran screening efficiency exists in a rice bran screening device.

An authorized publication number is CN 208627846U's utility model patent provides a rice processing chaff device. Including the casing, the fan, transmission, screen cloth device, through transmission multistage transmission, drive fan and screen cloth device's motion, the casing inner chamber activity has the screen cloth, the screen cloth center is fixed with the inner chamber, the inner chamber inner wall is fixed with the rack, the meshing of rack outer wall has the half-tooth gear, screen cloth both sides lateral wall evenly is fixed with the spring block, the fixed arc piece that sets up in spring block other end, the arc piece other end is pegged graft and is had the ball, casing both sides inner shell wall is fixed with the arc wall, the ball rolls in the arc wall inner wall. The utility model discloses utilize half tooth gear motion characteristic for rock about the screen cloth, separate polished rice and rice bran, reduce the destruction to the polished rice, the rolling friction on ball and arc wall surface reduces holistic frictional force, has set up the spring block between screen cloth and the arc wall and has cushioned, and the fixed spring that sets up in arc wall both ends can effectively reduce the collision that slides and bring, improves the stability of screen cloth motion.

However, the above patent documents still have the following disadvantages: 1. the rice enters the inner cavity of the shell from the inlet and falls to the bottom, the falling speed is high, the falling time is short, the removal rate of rice hulls and dust in the rice is greatly reduced by the fan, and the efficiency of the fan on screening chaff is reduced; 2. the wind that the fan produced can have some rice grains of rice in, and these rice grains of rice can't collect along with the wind goes out the casing inner chamber, have caused the waste.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, the utility model provides a rice processing chaff device can solve still to have following weak point in the above-mentioned patent document.

The utility model discloses a realize through following technical scheme: the utility model provides a rice processing chaff device, includes the casing, divide into in the casing and screen room and deposit room, the top left side of screening room is equipped with the feed inlet, and left conch wall runs through and sets up the fan, screen indoor from top to bottom has set gradually both sides to be fixed right screen the guide plate on the indoor lateral wall, the lower part of screening room is equipped with the sieve, the both ends of sieve stretch into in the recess of seting up on the wall of screening room conch, the flexible end of the other rigid coupling spring of part about the both ends of sieve, the stiff end of spring rigid coupling respectively is in top and bottom in the recess, the bottom middle-end of sieve is equipped with vibrating motor, screen room right side with the left side intercommunication of deposit room, the deposit room right side is equipped with the air outlet, the bottom of screening room is equipped with the discharge gate.

Furthermore, a fan cover is fixedly arranged at the air outlet of the fan.

Further, the top of the settling chamber is arc-shaped, and the bottom of the settling chamber is inclined towards the screening chamber.

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

1. the utility model discloses a set up the guide plate from top to bottom in proper order in the screening chamber, the guide plate that the slope set up can make the rice segmental whereabouts, has delayed the speed of whereabouts, and then has prolonged the time of rice whereabouts for the fan has enough time to get rid of the rice husk and the dust in the rice, has improved the efficiency of fan chaff.

2. The utility model discloses an adopt the design of screening room intercommunication deposit room, through the effect of deposit room for the wind speed descends, and then makes some rice grains of rice that have in the wind sink to the bottom of deposit room under the effect of gravity, and final landing is to screening on the sieve of room lower part.

Drawings

Fig. 1 is a sectional view of the present invention.

In the drawings: 1. a housing; 2. a screening chamber; 3. a settling chamber; 4. a feed inlet; 5. a fan; 6. a fan housing; 7. a baffle; 8. a sieve plate; 9. a groove; 10. a spring; 11. a vibration motor; 12. an air outlet; 13. and (4) a discharge port.

Detailed Description

A rice processing chaff device shown in fig. 1 in the attached drawings of the specification, including casing 1, divide into screening room 2 and deposit room 3 in the casing 1, the top left side of screening room 2 is equipped with feed inlet 4, the left conch wall runs through and sets up fan 5, from top to bottom set gradually right side in the screening room 2 and fix the guide plate 7 on screening room 2 inside wall, the lower part of screening room 2 is equipped with sieve 8, the both ends of sieve 8 stretch into the recess 9 of seting up on the conch wall of screening room 2, the upper and lower part in the both ends of sieve 8 is the flexible end of rigid coupling spring 10 respectively, the stiff end of spring 10 is the top and the bottom of rigid coupling in recess 9 respectively, the bottom middle-end of sieve 8 is equipped with vibrating motor 11, screening room 2 right side and the left side intercommunication of deposit room 3, deposit room 3 right side is equipped with air outlet 12, the bottom of screening room 2 is equipped with discharge.

An air outlet of the fan 5 is fixedly provided with an air cover 6.

The top of the settling chamber 3 is arc-shaped, and the bottom is inclined towards the screening chamber 2.

Rice enters the screening chamber 2 from the feed inlet 4, fall one by one on the guide plate 7, the wind that the fan 5 blew off takes away lighter rice husk and dust in the rice, get into the settling chamber 3, because the cavity of settling chamber 3 is higher than and is greater than the cavity of screening chamber 2, make the wind speed descend, some rice grains of rice that have in the wind sink to the bottom of settling chamber 3 under the effect of gravity, because the bottom of settling chamber 3 sets up to the slope of screening chamber 2, consequently, the final landing of the rice grain is on the sieve of screening chamber 2 lower part, the vibrating motor 11 that starts makes sieve 8 shake from top to bottom, because the flexible end of spring 10 is do not fixed in the upper and lower part in both ends of sieve 8, and the stiff end of spring 10 is respectively the top and the bottom in recess 9, therefore the stability of shaking from top to bottom of sieve 8 is good, screening through sieve 8 (the sieve aperture is greater than the particle diameter of rice granule) with big quality, The impurity particles with large volume are screened out, and the screened polished rice is collected through a discharge hole 13.

In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
