Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment 1

[0037] Please refer to Figures 1-8, the present utility model provides a technical solution: a color sorter with a powder blowing device, including: a frame 1, a feeding bin 2, a color sorting system 3, a first discharge pipe 5 and a second discharge pipe 51. A feeding bin 2 for feeding wheat or rice is arranged at the top of the frame 1. A color sorting system 3 is arranged below the feeding bin 2. A first discharge pipe 5 and a second discharge pipe 51 are installed between the color sorting system 3 and the frame 1. The frame 1 is provided with discharge grooves matching with the first discharge pipe 5 and the second discharge pipe 51. A feeding component 4 is installed between the color sorting system 3 and the feeding bin 2. The feeding component 4 includes a material limiting structure 41, an air outlet structure 42 and an air inlet structure 43;

[0038] The material limiting structure 41 is installed between the feeding bin 2 and the color sorting system 3, and the material limiting structure 41 is used for wheat or rice in the feeding bin 2 to flow into the color sorting system 3 for screening;

[0039] The air outlet structure 42 is installed on one side of the material limiting structure 41, and the air outlet structure 42 is used for discharging powdery particles adhered to wheat or rice;

[0040] The air inlet structure 43 is installed on the other side of the material limiting structure 41; the air inlet structure 43 is used for separating powdery particles from wheat or rice.

[0041] The material limiting structure 41 includes a feeding pipe 6 connected between the feeding bin 2 and the color sorting system 3. A rotating shaft 61 is rotatably connected at the feeding port of the feeding pipe 6. A material limiting roller 62 arranged inside the feeding pipe 6 is fixedly installed on the outer side of the rotating shaft 61;

[0042] When the color sorter is working, the wheat or rice to be color sorted flows into the feeding component 4 through the feeding bin 2, undergoes material limiting and powder removing treatment by the feeding component 4, then flows into the color sorting system 3 for color sorting and screening to remove impurities. The impurities flow out through the first discharge pipe 5, and the wheat or rice flows out through the second discharge pipe 51.

[0043] When the feeding component 4 is working, the rotating shaft 61 starts to rotate by the rotation of the motor 64, and the impeller 7, the centrifugal air wheel 8 and the material limiting roller 62 rotate synchronously; among them, the material limiting roller 62 is used for feeding a certain amount of wheat or rice each time it rotates, so as to avoid excessive input of wheat or rice affecting the screening effect of the color sorter. After a certain amount of wheat or rice is introduced through the material limiting roller 62, then through the blowing generated by the impeller 7 and the suction generated by the centrifugal air wheel 8, the powdery particles inside the color sorter are separated.

[0044] When the impeller 7 rotates, the air inlet of the second casing 65 starts to intake air, which flows into the second outlet pipe 71 and is introduced into a plurality of air outlet holes 73 through the second air inlet groove 72, and can blow air on the wheat or rice on the surface of the inclined plate 66. When designing the second air inlet groove 72 and the air outlet holes 73, the groove diameter of the second air inlet groove 72 from the air inlet end to the end is from large to small, and the aperture of the air outlet holes 73 from the air inlet end to the end close to the second air inlet groove 72 is also from large to small. In this way, when the air flow reaches the end, due to the change of the pipe diameter, the air flow changes from slow to fast and from gentle to rapid, blowing the powder particles to a higher height and at the same time blowing the wheat or rice to a certain height, so as to facilitate the better separation effect of the powdery particles from the wheat or rice and impurities;

[0045] When the centrifugal air wheel 8 rotates, the air inlet pipe 81 starts to intake air. The powdery particles that have been blown are introduced into the first air inlet groove 82 through a plurality of air inlet holes 83, and then flow out through the air inlet pipe 81 and are introduced into the first outlet pipe 84. In this way, it is avoided that the separated powdery particles re-adhere to the wheat or rice and impurities again, thereby further improving the powder blowing and separating effect of the color sorter.

[0046] One side of the frame 1 is fixedly installed with the first casing 63, and the side of the first casing 63 facing away from the frame 1 is fixedly connected with a motor 64. Both sides of the rotating shaft 61 extend to the outside of the frame 1, and one side is connected to the output shaft of the motor 64. When the motor 64 is driving, the impeller 7, the centrifugal air wheel 8 and the material limiting roller 62 are synchronously driven to rotate, and sealing treatment is adopted at each connection point;

[0047] The second casing 65 is fixedly installed on the side of the frame 1 facing away from the first casing 63;

[0048] A plurality of inclined plates 66 of the same size are installed in the feed pipe 6.

[0049] The inclined plates 66 are all fixedly installed in an inclined manner, and the surfaces of the inclined plates 66 are all designed in a stepped manner. A plurality of inclined plates 66 are adopted, and among the plurality of inclined plates 66, the first inclined plate 66 is inclined downward from left to right, and the second inclined plate 66 is inclined downward from right to left, and so on. Combining the stepped design of the surface of the inclined plate 66 and the design of the air inlet holes 83 and the air outlet holes 73 of the inclined plate 66, when the wheat or rice passes through a plurality of inclined plates 66, first through the step difference of the inclined plate 66, when the wheat or rice and impurities touch the next step, they bounce up a certain distance by their own elasticity and generate a certain vibration, then the attached powdery particles are initially separated, and then through the blowing and suction treatment of the air inlet holes 83 and the air outlet holes 73, the attached powdery particles are further separated.

[0050] The second air inlet groove 72 and the first air inlet groove 82 are respectively arranged in the inclined plates 66, and a plurality of air inlet holes 83 and a plurality of air outlet holes 73 are respectively arranged on the inclined plates 66;

[0051] The second air inlet groove 72 communicates with a plurality of air outlet holes 73;

[0052] The first air inlet groove 82 communicates with a plurality of air inlet holes 83. Among them, there are multiple groups of air inlet holes 83 and air outlet holes 73. Similarly, the aperture of the air outlet holes 73 from the air inlet end to the end of the second air inlet groove 72 gradually decreases from large to small. In this way, when the air flow reaches the end, due to the change in the pipe diameter, the air flow changes from slow to fast and from gentle to rapid, blowing the powder particles to a higher height. Among them, the aperture of the air inlet holes 83 near the air outlet of the first air inlet groove 82 is larger, and the aperture is smaller at the far away position. In combination with the design of multiple inclined plates 66, the air inlet holes 83 far away from the air outlet of the first air inlet groove 82 are closer to the next inclined plate 66. Therefore, a smaller suction force can be used. However, the air inlet holes 83 near the air outlet of the first air inlet groove 82 require a larger adsorption force to suck the separated powder-like particles.

[0053] The second air inlet groove 72 does not communicate with the first air inlet groove 82. Grids are installed on both the air outlet holes 73 and the air inlet holes 83. The aperture of the grid is smaller than the size of the powder-like particles, wheat or rice, and some impurities, which can isolate the inhalation of wheat or rice and ensure the normal transportation of wheat or rice.

[0054] The air inlet structure 43 includes an impeller 7 installed on the rotating shaft 61 inside the second housing 65;

[0055] A second air outlet pipe 71 is fixedly connected to the air outlet of the second housing 65, and the air outlet of the second air outlet pipe 71 is connected to the air inlet of the second air inlet groove 72;

[0056] One side of the second housing 65 facing away from the frame 1 adopts a through-port design for the external original air to be introduced into the second housing 65 through the impeller 7. Among them, the impeller 7 is a prior art, and its size can be changed according to the actual situation to avoid the phenomenon that wheat or rice is blown away from the inclined plate 66 at a relatively high height, resulting in the fragmentation of wheat or rice particles;

[0057] A second air outlet pipe 71 is fixedly connected to the air outlet of the second housing 65, the second air outlet pipe 71.

[0058] The air outlet structure 42 includes a centrifugal air wheel 8 installed on the rotating shaft 61 inside the first housing 63. An air inlet pipe 81 is fixedly installed at the air inlet of the first housing 63, and an air outlet pipe 84 is fixedly connected to the air outlet of the first housing 63;

[0059] The air inlet of the air inlet pipe 81 is connected to the air outlet of the first air inlet groove 82. Among them, the centrifugal air wheel 8 is a prior art, and its size can be changed according to the actual situation to avoid excessive adsorption force causing wheat or rice to adhere to the air inlet holes 83 and block them.

[0060] Embodiment 2

[0061] Such as Figure 3As shown, in the second embodiment, the inclined plate 66 is connected to the feed pipe 6 in a rotating manner, and the connecting shaft can be positioned by a torsion spring. When a certain amount of wheat or rice accumulates between the two inclined plates 66, the weight of the wheat or rice causes the next inclined plate 66 to rotate, expanding the through notch, thereby avoiding the phenomenon of wheat or rice accumulation and jamming, and ensuring the stability of the color sorter during use.
