Description

A kind of apparatus of selecting rice color

Technical field

The utility model belongs to technical field of food production, and in particular to a kind of apparatus of selecting rice color.

Background technology

Selecting rice color is one of the work screened using CCD optical image technologies to heterochromatic particle and impurity in rice Sequence.To be determined in wherein heterochromatic particle and impurity proportion i.e. percentage of impurity, rice material after rice material transports machining location to Percentage of impurity directly influences the precision of color separation of apparatus of selecting rice color, and percentage of impurity is higher, and precision of color separation is lower, and effect is poorer.Existing market Upper most of color

Machine precision of color separation when percentage of impurity is 2% is selected to reach 99.99% substantially.Color selector color can be influenceed by removing percentage of impurity Select outside effect,

Yield in unit interval is also one of key factor, and yield is inversely proportional in the i.e. unit interval with color selector precision and produced Amount is bigger, and color sorting effect is poorer.So it is general before start work, set according to the percentage of impurity of rice material, yield, species etc. The relevant parameters such as color selector mode of operation.After parameter setting is finished, selected rice is loaded into color selector by elevating mechanism and fed In bucket, rice now selects chute passage from feed hopper through oscillating feeder for one（That is color sorting passage, its surface answer flat smooth without Jump meter Xian Xiang）Feed.The grain of rice carry out arranging in chute passage shaping speed governing formed the uniform rice of individual layer speed it is fluent go out chute Passage, falls into CCD shot detections area.The data that color selector master control system is gathered according to CCD camera lenses are to meter Liu Jin rows point Analysis differentiates, meter Liu Zhong defective products is blown out into rice stream using high speed jet valve, into defective products bucket.The defective products once sorted Selected through Special-purpose lifting machine into two into rice bucket and carry out secondary color sorting.Superior rice material by secondary color sorting will be admitted to lower road work Sequence processing；Defective products is then determined as final defective products, and separately storage is handled.

Above-mentioned apparatus of selecting rice color operationally, due to being that can only be screened according to the color of rice, so as to select excellent Matter rice and rice inferior and part other impurities, but color sorting can not be carried out to the size of the grain of rice, therefore, generally require in color Used before choosing by special grain of rice size screening machine, the grain of rice is classified according to the difference of size.The problem of this design, exists In, because rice does not carry out color sorting also, therefore the operating pressure of screening machine is excessive, power consumption increase, influence work efficiency and Precision.

Utility model content

The utility model is intended to provide a kind of apparatus of selecting rice color, to solve at present before apparatus of selecting rice color with screening machine pair When rice carries out the screening of size, screening machine operating pressure can be caused excessive, the problem of influenceing efficiency.

Feed hopper, oscillating feeder, rice are installed in a kind of apparatus of selecting rice color in this programme, including body, body Slideway, light source, background board, CCD camera lenses, the Electron-Optics Analysis instrument, electronics steam jet atomizer and discharging bin, the discharging bin include Collect the one-level storehouse of superior rice and collect in two grades of storehouses of rice inferior, the one-level storehouse and be provided with reducing gear and vibratory sieve, institute Stating reducing gear includes receiving hopper and deceleration passage, and receiving hopper is connected with deceleration passage, and receiving hopper is located at the lower section of rice slideway Flap is provided with superior rice, the deceleration passage for receiving, the deceleration passage is used for positioned at the surface of vibratory sieve will Superior rice is transported on vibratory sieve, and the vibratory sieve includes the sieve plate with sieve aperture, and the sieve plate tilts 5 ° with horizontal direction and set Put, the lower end of the sieve plate and lower section are placed with the collection frame for collecting the grain of rice.

Principle of the present utility model：When in use, the superior rice by screening is dropped in one-level storehouse the utility model, first First receiving hopper receives the superior rice fallen down from rice slideway, and whole superior rices concentration is transported into deceleration passage, slows down Flap in passage can slow down the progress of superior rice, its falling speed is become slow.If not to the whereabouts of superior rice Speed is slowed down, and when superior rice is dropped on vibratory sieve at a high speed, can be caused strong collision, on the one hand can be crashed the grain of rice, The quality of the grain of rice is influenceed, on the other hand the grain of rice can be caused to beat so that the screening effect of the grain of rice on the vibrating is not good.And it is our The reducing gear of case, can allow superior rice falling on vibratory sieve gently, it is ensured that the integrality of the grain of rice and the stability of screening. After the grain of rice is dropped on vibratory sieve, due to there is the sieve plate with sieve aperture on vibratory sieve, sieve aperture can be dimensioned to desired classification Grain of rice size, the so less grain of rice will be fallen from sieve aperture, collected by the collection frame below sieve plate.And larger rice Incline direction of the grain just along sieve plate is slid, and in the collection frame for finally dropping to sieve plate lower end, so far realizes grain of rice size Screening.

The beneficial effects of the utility model：, will due to being all that grain of rice size is screened before the color sorting of rice at present Rice or impurity inferior are all sieved.And rice inferior or impurity need not carry out size screening, this results in screening machine and done Many useless work, cause the operating pressure of screening machine excessive.The innovative sieve eliminated before color sorting of the utility model Machine is selected, and sorting mechanism is devised in color selector, first allows rice to carry out color sorting, rice inferior and impurity is sifted out, then to excellent Matter rice carry out size screening, that is, realize color sorting and screening it is two-in-one, decrease screening step operating pressure.

Further, the flap includes some pieces, and some pieces of flaps are interlaced and downward in deceleration passage It is obliquely installed.After rice is dropped in deceleration passage, plate can be decelerated and stop speed, the slowing effect of this design is preferable, and And can be as needed, change the effect of deceleration by changing the angle of inclination of flap.

Further, the flap in deceleration passage in the shape of a spiral.This design is advantageous in that rice on flap It is very steady during slip.

Further, the both sides of the sieve plate are provided with the baffle plate for preventing that the grain of rice from dropping, and can avoid the grain of rice in vibration screening, Dropped from sieve plate.

Further, the sieve plate is provided with sponge section, and sponge section is located at the underface of deceleration passage, when rice is from subtracting It when fast passage is dropped on sieve plate, can drop in sponge section, be slowed down by sponge section, it is to avoid the hard contact of rice and sieve plate.
