Description

A kind of LED-based multifunctional color selection machine

Technical field

The utility model relates to a kind of LED-based multifunctional color selection machine.

Background technology

Color selector is a machinery commonly used in grain, food, medicine and commercial production, judges the quality of grain as the grain color selector according to the color of grain, and rejects according to the particle ejection inferior that the speed that grain falls will be fallen before the puff prot.

In the prior art, the color selector light source all adopts daylight lamp, and color all is that changeless, such light source can only adapt to selection a kind of or the similar color material, be well to work for other color material, and power consumption is bigger.

In the prior art, light-source brightness immobilizes, and the range of adjustment of background board is also very limited, can only adapt to a kind of material of or close intensity of light reflection like this, and for various materials, color selector can't adapt to, and can not work.

Summary of the invention

The utility model has solved in the prior art common photochromic single, and conformability is poor, selects problems such as precision is low.A kind of LED-based multifunctional color selection machine, comprise elevating hopper, it under the elevating hopper vibrating bunker, the vibrating bunker below is the chute that certain angle is arranged with surface level, the chute below is provided with receiving hopper and waste material bucket, both sides at the downward extended line of chute are provided with light source, in the both sides of the downward extended line of chute an optical sensor is arranged respectively, in the both sides of the downward extended line of chute a background board corresponding with optical sensor is arranged respectively, the background board below is provided with puff prot, optical sensor is connected with high speed processor respectively with puff prot, it is characterized in that: described light source is a light emitting diode.Described light source is a kind of in white light source, red light source, green light source, blue-light source, the yellow light sources.Described light source can be for being in white light source, red light source, green light source, blue-light source, the yellow light sources two or more.Described light source is connected with the light source controller that is used to regulate brightness.Advantage of the present utility model is, grain separation accuracy height, scope is wide, can carry out the separation of various materials, cost is low, waste little, high efficiency, energy savings.

Description of drawings

Accompanying drawing 1 is a structural representation of the present utility model,

Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

Comprising elevating hopper 1 among the figure, is vibrating bunker 2 under the elevating hopper 1, and vibrating bunker below be several chutes parallel to each other 3, and chute and surface level have certain angle, its angle greatly about be 60 spend about.The chute below is provided with receiving hopper 4 and waste material bucket 5, receiving hopper 4 is corresponding with chute 3 bottoms, in the both sides of the downward extended line of chute an optical sensor 6/7 is arranged respectively, both sides at the downward extended line of chute are provided with light source 8/9/10/11, in the both sides of the downward extended line of chute a background board corresponding with optical sensor 12/13 is arranged respectively, background board is below the light source of correspondence, be provided with puff prot 14 below background board, optical sensor and puff prot are electrically connected with high speed processor 15 respectively.Described light source is a LED.Described light source can be two or more, preferred four light sources.Described light source can be in white, red, green, blue, the yellow one or more, and the user can use separately with a kind of color light, and the light that also can open several different colours simultaneously is used.Described light source is connected with a light source controller respectively, is used to control the color and the brightness of light source.

Before work, get rid of external interference earlier, the utility model is placed indoor, a large amount of grains to be separated are sent into elevating hopper, and the elevating hopper upper shed is big, and under shed is little, grain drains to vibrating bunker from elevating hopper, vibrating bunker below be some chutes parallel to each other, the groove number of chute be ten to hundreds of or dull and stereotyped, chute and surface level have 60 to spend angles.Grain slides from smooth chute, skids off in chute 3 bottoms, does inclined throw movements aloft, drops in the receiving hopper.

In the work, grain falls from chute and does inclined throw movements aloft, the light that light source sends is mapped on the background board, reflex on the optical sensor through background board, the light of light source is mapped to and reflexes on the optical sensor on the grain, two-beam is mapped to the data that produce in the optical sensor, passes to high speed processor and compares computing.If the grain color is normal, puff prot is not worked, and grain can continue freely to fall, and enters in the receiving hopper; If grain often is off color, after the high speed processor comparison operation, send instruction, make puff prot ejection high velocity air, the undesired grain of falling the puff prot front is blown out, fall in the waste material bucket.Because the arithmetic speed of high speed processor is enough fast, can set the height and the time delay of puff prot in advance, make the grain of pinpointing the problems after testing when puff prot is jet, just drop on puff prot the place ahead and sprayed by air-flow.

Color selector all adopts daylight lamp as light source in the prior art, and light color is fixed, and can not change.Because the choosing of the look of different material needs light sources of different colors, the color selector of prior art can't be accomplished.The light source that the utility model adopts can be two or more, preferred four light sources.Adopt the LED semiconductor luminotron, can the arbitrfary point brilliant white, color such as red, blue, green, Huang is as light source, can also light two or more color LED simultaneously and allot versicolor coloured light as light source.Material particles whatsoever needs the light source of what color, can both realize, makes the utility model can be applicable to various materials like this, has increased the function of color selector greatly.

The variety classes material is because color difference, reflective intensity difference, described light source is connected with the light source controller that is used to regulate brightness, make the brightness of each light source all can independently realize continuously adjustable, the optimum colour choosing that makes color selector can be adjusted to different material needs the optimal brightness of brightness and background board, make the utility model can both under optimum Working, work, help improving precision of color separation various materials.
