The following describes in detail the specific structure of the rice color selector 1 and the corresponding technical effects thereof according to the embodiment of the present invention with reference to the accompanying drawings.

Referring to fig. 1-2, a rice color sorter 1 provided by the present invention includes a slide carriage 10, a feeding unit 20, a spray valve executing unit (not shown), an image collecting unit (not shown), and a valve dividing data processing unit (not shown).

Wherein the feeding unit 20 is equipped with many rice and is used for carrying the swift current board 10 with the rice, and the swift current board 10 is provided with a plurality of spouts 11 that set gradually along width direction, and the cell wall of every chute 11 is curved wall and extends along the length direction of swift current board 10, and every chute 11 is used for supplying single rice to pass through, and length direction is the contained angle with width direction, and wherein a plurality of spray valve execution units and a plurality of chute 11 one-to-one, every spray valve execution unit is used for spraying the heterochromatic dysmorphism grain that corresponds chute 11 dropped, and it can be understood that the spray valve execution unit can spout gas in order to reject the heterochromatic dysmorphism grain that detects.

In particular, in the present embodiment, the width direction is perpendicular to the length direction, and the above-described perpendicular is not to be construed as being a strict sense of perpendicular, but may be a substantially perpendicular shape.

The image acquisition unit is used for detecting the color of the rice on the slide carriage 10, that is, the image acquisition unit is used for detecting whether the rice of the slide carriage 10 or the rice falling from one end of the slide carriage 10 far away from the feeding unit 20 has abnormal color and special grains.

In some existing rice color selectors 1, a flat plate type slide carriage 10 is adopted, that is, after the feeding unit 20 conveys the rice onto the feeding unit 20, a plurality of rice slides up and down directly on the flat plate type slide carriage 10, and since the flat plate type slide carriage 10 has no limitation on the rice by the groove wall of the chute 11 in the process of sliding down, the posture of the rice is complex in the process of sliding down, part of single abnormal-color abnormal-shape grains can be removed by the gas of a plurality of spray valve executing units, the abnormal-color abnormal-shape grains cannot be removed accurately when the abnormal-color abnormal-shape grains are removed by the rice spray valve executing units, the carrying-out ratio can be influenced, and the carrying-out ratio can be understood as the mass ratio of good rice in the sorted removed matters after the abnormal-color abnormal-shape grains are removed in the sorting process.

In this embodiment, since the chute 10 is provided with the plurality of chutes 11 sequentially arranged in the width direction, the wall of each chute 11 is curved and extends along the length direction of the chute 10, when the feeding unit 20 conveys the rice to the chute 10 provided in this embodiment, the plurality of rice will enter different chutes 11, the rice will flow out from different chutes 11, the image capturing unit will capture the color of the rice on the chute 10, and when the image capturing unit detects the abnormal-color special-shaped grains, that is, when the image capturing unit captures the abnormal-color special-shaped grains, the nozzle valve executing unit corresponding to the chute 11 is used for rejecting the abnormal-color special-shaped grains falling from the chute 10.

In the process of falling of rice, different rice can enter different chute 11, under the restriction of the wall of chute 11, rice in each chute 11 can not fall into other chute 11, and when installing the valve actuating unit, a plurality of valve actuating units one-to-one correspond a plurality of chute 11, that is to say, each valve actuating unit is used for rejecting the heterochromatic special-shaped grain that drops on corresponding chute 11 through the gas of blowout, therefore, can avoid when rejecting heterochromatic special-shaped grain, because partial single heterochromatic special-shaped grain can be rejected by the gas of a plurality of valve actuating units, can not accurately reject heterochromatic special-shaped grain when rejecting, consequently, the slide carriage 10 provided by this embodiment can reduce the take-out ratio.

In addition, since the chute wall of the chute 11 in the embodiment is curved, and the outer contour of a part of rice is also approximately curved, the chute 11 on the chute 10 in the embodiment can be more suitable for rice, so that the rice can slide in the chute 11 more stably in the process of sliding down in the chute 11, and the condition of material jump is not easy to occur.

Alternatively, in some embodiments, the interior walls of the chute 11 are curved walls, the chute 11 has valleys 111, that is, the chute 11 has valleys 111 opposite the opening of the chute 11, and the chute 11 is symmetrical about the valleys 111. The above symmetry is not to be construed as being limited to a strict sense of symmetry, and may be substantially symmetrical.

It will be appreciated that the symmetry of the chute 11 with respect to the trough 111 enables the rice to slide down the chute 11 more stably.

Of course, in other alternative embodiments, the chute 11 may also be symmetrical without being limited to the trough 111.

With continued reference to fig. 2, optionally, to avoid stress concentrations between adjacent chutes 11, resulting in a reduced service life of the carriage 10, in this embodiment, the outer sidewalls of any two adjacent chutes 11 are arc-transitionally connected.

In the present embodiment, each chute 11 on the slide carriage 10 extends in the longitudinal direction of the slide carriage 10, and the plurality of chutes 11 are arranged in the width direction in order, and the slide carriage 10 in the present embodiment is a rectangular plate, and therefore, the length of each chute 11 on the slide carriage 10 is substantially the same.

In some existing rice color selectors 1, the extending directions of the chute 11 on the slide carriage 10 are different, and the lengths of the chute 11 are also different, so that the sliding down time of the rice leaving the slide carriage 10 from the different chute 11 is greatly different, and the difficulty of further sorting at the rear end is increased.

That is, in the present embodiment, the time from the time when different rice slides up and down from the chute 11 to the time when the rice leaves the chute 10 is substantially the same, so that the difficulty in the subsequent sorting process can be reduced.

In some existing rice color selector 1, the chute wall of the chute 11 on the chute 10 has a limiting structure for reducing the falling speed of rice in the extending direction of the chute wall, and because of the limiting structure, in the falling process of rice, after touching the limiting structure, the rice is easy to jump, that is, the rice is easy to directly leave the material plate, thereby influencing the clean rate, and because the limiting structure can reduce the falling speed of rice, the rice sorting efficiency is reduced.

Since the trough walls in the present embodiment are curved walls, that is, the inner trough walls of the trough 11 are entirely smooth curved walls, the rice is limited only in the width direction in the process of sliding down in the trough 11, so that the rice in one trough 11 is prevented from entering the other trough 11 without being subjected to resistance in the length direction, that is, the rice can slide down smoothly in the process of sliding down in the trough 11 without being subjected to resistance, the speed of sliding down the rice can be ensured, that is, the speed of leaving the chute 10 from the rice can be ensured, and the efficiency of sorting the rice can be effectively ensured.

In detail, in the present embodiment, since each chute 11 is configured to pass a single row of rice, that is, only a plurality of rice can pass in a row within each chute 11, two rice grains cannot exist within each chute 11 in the width direction.

The width dimension of the chute 11 on the slide carriage 10 of some existing rice color selector 1 is far greater than the dimension of rice, so that adhesion or overlapping between rice and rice in the chute 11 is easy to occur, and therefore, when the spray valve executing unit rejects heterochromatic special-shaped grains through air injection, good rice adhered or overlapped with heterochromatic special-shaped grains is easy to reject together, the carrying-out ratio of the sorting process is reduced, and because stacking easily occurs between rice grains, the image collecting unit can not collect heterochromatic special-shaped grains blocked in overlapped rice grains, the pressure of the subsequent further sorting procedure is increased, and the sorting efficiency is reduced.

Therefore, the rice is in the gliding in-process in chute 11 that this embodiment provided, is difficult for appearing in chute 11 between grain of rice and the condition of adhesion or overlapping of grain of rice, consequently, spout valve execution unit is in the in-process that jet-propelled is rejected, is difficult for appearing because heterochromatic dysmorphism grain is sheltered from by good rice, can't accurately reject heterochromatic dysmorphism grain, has improved the rate of cleaning, also can improve separation efficiency.

In the case of the carriages 10 of the same width size, since the width size of the chute 11 on the carriage 10 is excessively large, the number of the chute 11 on one carriage 10 may be reduced, and since the number of one chute 11 is small, the efficiency of sorting rice may be affected.

In the present embodiment, since each chute 11 is used for passing a single row of rice, more chutes 11 can be provided on the same width dimension of the chute 10 than one chute 11 in the width direction of the chute 10 capable of accommodating two or more rice, and thus the sorting efficiency can be improved.

Alternatively, in the present embodiment, the width dimension of the rice is w, and the maximum width dimension of the chute 11 ranges from 1.1w to 1.75w, that is, the maximum width dimension of the chute 11 is between 1.1 times the width dimension of the rice and 1.75 times the width dimension of the rice.

For example, the width dimension of a common rice is 2-3 mm, and in this embodiment, the maximum width dimension of the chute 11 on the chute 10 may be in the range of 3.3-3.5 mm. Taking 300mm as an example of the width dimension of the slide carriage 10, the number of the chute 11 on the slide carriage 10 in this embodiment can be 86-91, compared with the existing slide carriages 10, the number of the chute 11 on the slide carriage 10 is greatly increased under the condition that the overall dimension of the slide carriage 10 is unchanged, and the yield is increased, that is, through the rice color sorter provided by this embodiment, the carrying-out ratio can be reduced, the yield and the sorting rate can be also improved, and the sorting efficiency is effectively improved.

Of course, in other embodiments, the relationship of the maximum width dimension of the chute 11 to the width dimension of the rice is not limited to the above, as long as it is ensured that the chute 11 can accommodate only one grain of rice in the width direction.

Alternatively, in this embodiment, the slide carriage 10 is disposed obliquely, and the included angle formed between the slide carriage 10 and the horizontal plane is smaller than or larger than 90 °. That is, the slide 10 is not perpendicular to the horizontal plane when the rice color selector 1 of the present embodiment is placed on the plane.

In some existing rice color separators 1, the slide carriage 10 is perpendicular to the horizontal plane, and it can be understood that in the direction perpendicular to the slide carriage 10, the restriction capability of the slide carriage 10 on rice is weak, so that the rice sliding down in the slide carriage 10 is easy to diverge, that is, the rice sliding up and down in the slide carriage 10 is easy to separate from the rice, and the material jumping is serious, which affects the sorting effect of the rice color separator 1.

In this embodiment, the slide carriage 10 is not perpendicular to the horizontal plane, so that the slide carriage 10 can be ensured to have a certain restraining force on the rice, and the rice is prevented from being separated from the slide carriage 10 in the process of sliding down in the chute 11.

In addition, in alternative embodiments, the angle between the carriage 10 and the horizontal is in the range of 45-75 °. In detail, in this embodiment, the included angle between the slide carriage 10 and the horizontal plane is 60 °, so that the rice on the slide carriage 10 has a faster downward sliding speed, the sorting efficiency is ensured, and the slide carriage 10 can also be ensured to have a certain restraining force on the rice in the chute 11.

Of course, in other embodiments, the included angle between the slide carriage 10 and the horizontal plane may be other angles, such as 40 °, 44 °, 48 °, 50 °, 55 °, 70 °, etc.

Optionally, the slide carriage 10 is formed by adopting an aluminum alloy die casting process, and the surface of the slide carriage 10 is subjected to hard anodic oxidation treatment, so that the hardness and wear resistance of the surface of the slide carriage 10 are increased, and the friction coefficient of the surface of the slide carriage 10 is reduced, so that rice can smoothly slide down in the chute 11, and the service life of the slide carriage 10 is prolonged.

Of course, in alternative embodiments, the carriage 10 is not limited to the aluminum alloy die casting described above, but may be die casting of other materials, and the surface may also increase the hardness and wear resistance of the carriage 10 in other ways.

Optionally, the rice color selector 1 further includes a control unit, the control unit is connected with the valve dividing processing unit and the image acquisition unit in a communication manner, the valve dividing data processing unit is connected with the image acquisition unit and the plurality of spray valve execution units in a communication manner, and the valve dividing data processing unit is used for controlling the opening degree of the valve in the spray valve execution units.

Referring to fig. 3 to 4, in detail, the rice is conveyed from the feeding unit 20 to the plurality of chutes 11 arranged at intervals along the width direction on the chute 10, the plurality of rice slides down in different chutes 11, the image acquisition unit acquires images, the control unit acquires images acquired by the image acquisition unit, the existing theoretical coverage area of the spray valve execution unit in the marking position sprays air, and the radial fine adjustment of the coverage area of each spray valve execution unit is performed according to the distribution of the actual rice on the images, that is, the opening degree of each spray valve execution unit is adjusted through the valve dividing data processing unit, so as to adjust the coverage area of the air sprayed by the spray valve execution unit, and the rice on each chute 11 is located in the range of the air sprayed by the corresponding spray valve execution unit when falling from one end of the chute 11 far from the feeding unit 20, so that single abnormal-color special-shaped grains are prevented from being located in the range of the plurality of spray valve execution units, and compared with the fine adjustment of the spray valve execution units, the carrying out ratio is reduced, and the sorting efficiency of the rice is improved.

In summary, the rice color sorter 1 provided by the embodiment of the invention includes the slide carriage 10, the slide carriage 10 is provided with the plurality of the chute 11 sequentially arranged along the width direction, the chute width is adapted to the rice width, the number of the chute on the slide carriage is increased, the chute wall of each chute 11 is a curved wall and extends along the length direction of the slide carriage 10, each chute 11 is used for allowing single-row rice to pass through, and the length direction forms an included angle with the width direction. The rice can be limited in the width direction by the cell wall of chute 11 when the chute 11 is slided down in, and the rice in every chute 11 can not fall into other chute 11, can improve the clean rate to only can supply a plurality of rice to arrange into a line in every chute 11 and pass through, consequently, can not exist two rice in the width direction in every chute 11, the rice is difficult for appearing in the in-process that chute 11 provided by this embodiment slided in the chute 11 in the adhesion or the condition of overlapping between rice grain and the rice grain, when increasing output, still improved clean rate, and reduced the take-out ratio, the effectual separation efficiency that has improved.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art.
