Description

Technical Field

[0001] This utility model belongs to the field of agricultural product processing technology, specifically relating to a grain color sorter. Background Technology

[0002] In the field of agricultural product processing, grain color sorters are key equipment for achieving fine sorting of grains. Their core principle is to use optical detection technology to identify discolored particles in grains and remove them through airflow nozzles.

[0003] However, traditional color sorters are usually equipped with a single fixed nozzle group, which is inconvenient to switch and difficult to adapt to the differences in shape, size and weight of different types of grains (such as buckwheat, red beans, etc.), affecting the effect of air-powered sorting of grains. Utility Model Content

[0004] The purpose of this invention is to provide a grain color sorter that can easily select different nozzle groups to perform wind-powered sorting of different grains, ensuring the effectiveness of the grain color sorter in wind-powered sorting of grains.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A grain color sorter includes a storage bin, a connecting shell fixedly connected to the upper side of the storage bin, an outer cover fixedly connected to the upper side of the connecting shell, a chute and a feed hopper located above the chute fixedly connected to the upper side of the outer cover, a feed inlet on the upper side of the outer cover, a discharge inlet on the lower side of the outer cover, a light source, a background plate and a sensor fixedly connected inside the outer cover, an airflow nozzle provided on the rear side of the connecting shell, a finished product trough provided on the rear side of the storage bin, a finished product feed inlet on the upper side of the finished product trough, and an airflow nozzle including a protective shell fixedly connected to the rear side of the connecting shell, a drive motor and an air pump fixedly connected to the outer side of the protective shell, a central rod fixedly connected to the output end of the drive motor, the central rod being rotatably connected inside the protective shell, and at least two nozzle assemblies connected to the air pump fixedly connected to the outer side of the central rod.

[0007] Furthermore, the nozzle assembly includes an air duct fixedly connected to the outside of the central rod, the air duct being connected to the air pump via a main hose, and a plurality of equally spaced spray valves being fixedly connected to the outside of the air duct.

[0008] Furthermore, the nozzle assembly includes an air duct fixedly connected to the outside of the central rod. The air duct is connected to the air pump via a main hose. Multiple equidistantly arranged angle adjustment brackets are fixedly connected to the outside of the air duct. A second spray valve is fixedly connected to the angle adjustment bracket. The second spray valve is connected to the air duct via a branch hose.

[0009] Furthermore, the angle adjustment bracket includes a C-shaped bracket fixedly connected to the air duct, the second spray valve is rotatably connected inside the C-shaped bracket, and a first motor is fixedly connected to the outside of the C-shaped bracket. The output end of the first motor is drively connected to the second spray valve.

[0010] Furthermore, the front end of the second spray valve is fixedly connected to an air outlet area adjustment mechanism. The air outlet area adjustment mechanism includes a hollow box fixedly connected to the front end of the second spray valve. An air inlet communicating with the second spray valve is opened on the rear side of the hollow box, and an air outlet is opened on the front side of the hollow box. Two vertically adjustable movable plates are installed inside the hollow box, and ventilation volume adjustment holes are opened on both movable plates.

[0011] Furthermore, both ventilation volume regulating holes include a large semicircular hole, a small semicircular hole, and an isosceles trapezoidal connecting hole. The isosceles trapezoidal connecting hole is located between the large semicircular hole and the small semicircular hole, and the size of the isosceles trapezoidal connecting hole gradually decreases from the end closer to the large semicircular hole to the end closer to the small semicircular hole. The large semicircular hole, the isosceles trapezoidal connecting hole, and the small semicircular hole of one ventilation volume regulating hole are arranged in order from top to bottom, while the large semicircular hole, the isosceles trapezoidal connecting hole, and the small semicircular hole of the other ventilation volume regulating hole are arranged in order from bottom to top.

[0012] Furthermore, a second motor is fixedly connected to the hollow box, and a rotating rod is fixedly connected to the output end of the second motor. Two threaded wires are fixedly connected to the outer side of the rotating rod, and the two threaded wires have opposite thread directions. Movable blocks are fixedly connected to both movable plates, and the two movable blocks are threadedly connected to the two threaded wires respectively.

[0013] The technical effects achieved by this utility model are as follows:

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-7 As shown, a grain color sorter includes a storage box 1 and a control host. A connecting housing 9 is fixedly connected to the upper side of the storage box 1. An outer cover 2 is fixedly connected to the upper side of the connecting housing 9. A chute 3 and a feed hopper 4 located on the upper side of the chute 3 are fixedly connected to the upper side of the outer cover 2. A feed inlet is opened on the upper side of the outer cover 2, and a discharge outlet is opened on the lower side of the outer cover 2. The grains inside the feed hopper 4 fall onto the chute 3, then slide down the chute 3 into the interior of the outer cover 2, and then fall into the interior of the connecting housing 9 through the discharge outlet.

[0026] The outer casing 2 is fixedly connected to a light source 10, a background plate 11, and a sensor 12. Both the light source 10 and the sensor 12 are electrically connected to the control host. At this time, the light source 10 illuminates the inside of the outer casing 2. The background plate 11 and the sensor 12 are opposite each other. The sensor 12 can be a high-precision CCD / CMOS camera. The sensor 12 collects image data of the grains, extracts and analyzes the features of the image data, and then distinguishes the grains.

[0027] Here, the control host has a built-in database of grain types, and matches the corresponding nozzle group parameters with the image data collected by sensor 12.

[0028] like Figure 3 As shown, Figure 3 The right side of the middle section shows the front of the grain color sorter. Figure 3 The left side of the middle section is the rear side of the grain color sorter. An airflow nozzle is provided on the rear side of the connecting housing 9. A finished product trough 5 is opened on the rear side of the storage box 1. A finished product inlet 7 is opened on the upper side of the finished product trough 5. A defective product trough 6 is opened on the front side of the storage box 1. A defective product inlet 8 is opened on the upper side of the defective product trough 6. At this time, when the grain falls inside the connecting housing 9, if no defective grain with a different color is detected, the airflow nozzle is not activated. The grain falls directly into the finished product trough 5 through the finished product inlet 7 under the action of gravity. If defective grain with a different color is detected, the airflow nozzle is activated to blow the defective grain with a different color forward, so that the defective grain with a different color can fall into the defective trough 6 through the defective product inlet 8 for storage.

[0029] The technical features described above have been disclosed in Chinese patents with authorization announcement numbers CN201921839U and CN205341318U, and will not be described in detail in this technical solution.

[0030] like Figures 1-7 As shown, the core of this technical solution lies in the improvement of the airflow nozzle. Specifically, the airflow nozzle includes a protective shell 13 fixedly connected to the rear side of the connecting housing 9. A drive motor 14 and an air pump 15 are fixedly connected to the outside of the protective shell 13. A central rod 16 is fixedly connected to the output end of the drive motor 14. The central rod 16 is rotatably connected inside the protective shell 13. At least two nozzle groups connected to the air pump 15 are fixedly connected to the outside of the central rod 16. Different nozzle groups can be used for different grains. For example, the first nozzle group is suitable for buckwheat, and the other nozzle group is suitable for red beans. When applied to different grains, the drive motor 14 is started by the control host to drive the central rod 16 to rotate. The nozzle group opposite to the falling grain can be adjusted, and the nozzle group can be switched relatively easily. Different nozzle groups can be selected to perform wind-powered sorting of different grains, ensuring the effect of wind-powered sorting of grains by the grain color sorter.

[0031] like Figures 2-4As shown, one type of nozzle assembly includes an air duct 17 fixedly connected to the outside of the central rod 16. The air duct 17 is connected to the air pump 15 via the main hose 19. Several spray valves 18 arranged at equal intervals are fixedly connected to the outside of the air duct 17. The air pump 15, the main hose 19, the air duct 17, and the spray valves 18 form the first air blowing pipeline. At this time, after detecting the substandard grain with discoloration, the host machine opens the spray valve 18 opposite to the substandard grain, and the air blown out by the spray valve 18 pushes the substandard grain with discoloration, applies a thrust to the substandard grain with discoloration, and causes the substandard grain with discoloration to fall into the substandard feed inlet 8.

[0032] Here, buckwheat grains are small and lightweight, and the buckwheat can be blown by fixing the airflow through the small opening of the spray valve 18. In addition, since the spray valve 18 is small in size, a large number of spray valves 18 can be set, so that the buckwheat can be blown accurately through a large number of spray valves 18.

[0033] Another type of nozzle assembly, such as Figures 2-5 As shown, the nozzle assembly includes an air duct 17 fixedly connected to the outside of the central rod 16. The air duct 17 is connected to the air pump 15 via the main hose 19. Multiple equidistantly arranged angle adjustment brackets are fixedly connected to the outside of the air duct 17. A second spray valve 22 is fixedly connected to the angle adjustment bracket. The air outlet size of the second spray valve 22 is different from that of the first spray valve 18. The second spray valve 22 is connected to the air duct 17 via the branch hose 23. The air pump 15, the main hose 19, the air duct 17, the branch hose 23, and the second spray valve 22 form a second air blowing pipeline. At this time, after detecting the substandard grain with discoloration, the second spray valve 22 opposite to the substandard grain is opened by controlling the host. The air blown out by the second spray valve 22 pushes the substandard grain with discoloration, applying a thrust to the substandard grain, causing it to fall into the substandard feed inlet 8. During this process, the angle adjustment bracket can be activated to adjust the angle of the second spray valve 22, so that the substandard grain at different positions can be blown.

[0034] like Figures 4-5 As shown, the angle adjustment bracket includes a C-shaped bracket 20 fixedly connected to the air duct 17, a second spray valve 22 rotatably connected inside the C-shaped bracket 20, and a first motor 21 fixedly connected to the outside of the C-shaped bracket 20. The output end of the first motor 21 is connected to the second spray valve 22. At this time, by starting the first motor 21, the second spray valve 22 can be driven to rotate, thereby adjusting the air outlet angle of the second spray valve 22 in a relatively simple way.

[0035] like Figures 4-7As shown, due to the significant differences in the external dimensions of different types of grains, this technical solution includes a fixed air outlet area adjustment mechanism connected to the front end of the second spray valve 22. The air outlet area adjustment mechanism includes a hollow box 24 fixedly connected to the front end of the second spray valve 22. An air inlet 25 communicating with the second spray valve 22 is opened on the rear side of the hollow box 24, and an air outlet 26 is opened on the front side of the hollow box 24. Two vertically adjustable movable plates 27 are installed inside the hollow box 24. Both movable plates 27 are provided with ventilation volume adjustment holes 28. The overlapping area of ​​the two ventilation volume adjustment holes 28 is the effective air outlet area. At this time, the air entering through the air inlet 25 flows through the effective air outlet area to the air outlet 26, and then is discharged and blown towards the grains.

[0036] Here, the inner wall of the hollow box 24 and the movable plate 27 need to have good sealing performance so that the airflow entering the interior of the hollow box 24 can be concentrated and flow through the effective air outlet area.

[0037] Red bean particles are large and heavy. Switching to the adjustable angle airflow of spray valve 22 allows for the removal of discolored particles with a larger air volume.

[0038] Both ventilation volume regulating holes 28 include a large semicircular hole, a small semicircular hole, and an isosceles trapezoidal connecting hole. The isosceles trapezoidal connecting hole is located between the large semicircular hole and the small semicircular hole, and the size of the isosceles trapezoidal connecting hole gradually decreases from the end closer to the large semicircular hole to the end closer to the small semicircular hole. The large semicircular hole, the isosceles trapezoidal connecting hole, and the small semicircular hole of one ventilation volume regulating hole 28 are arranged in order from top to bottom, while the large semicircular hole, the isosceles trapezoidal connecting hole, and the small semicircular hole of the other ventilation volume regulating hole 28 are arranged in order from bottom to top.

[0039] The movable plate 27 can be moved by magnetic force, or as... Figures 6-7 As shown, the second motor 30 drives the movable plate 27 to move. Specifically, the second motor 30 is fixedly connected to the hollow box 24, and the output end of the second motor 30 is fixedly connected to the rotating rod 31. Two threaded wires 32 are fixedly connected to the outside of the rotating rod 31. The threads of the two threaded wires 32 are opposite in direction. Movable blocks 29 are fixedly connected to both movable plates 27. The two movable blocks 29 are threadedly connected to the two threaded wires 32 respectively. At this time, when the second motor 30 drives the two threaded wires 32 to rotate synchronously, the two movable plates 27 can be moved in opposite directions synchronously.

[0040] Here, the second motor 30, the first motor 21, the second spray valve 22, the first spray valve 18, the drive motor 14, and the air pump 15 are all electrically connected to the control host.

[0041] The spray valve includes a solenoid valve connected to the air duct 17 and a straight pipe connected to the solenoid valve. When the solenoid valve is opened, air can be discharged through the straight pipe.

[0042] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
