[0038] As shown in Figure 1 、 Figure 2 ,Figure 4 And Figure 5 As shown in the figure, the rotating mechanism 5 comprises a motor 51, a second full gear 52, a first gear disc 53, a second gear disc 54, a sliding frame 56, a guide rod 57, a second roller 58 and a third full gear 59. The motor 51 is installed on the rear side of the inner bottom wall of the frame 1. The motor 51 is a double-shaft motor. The motor 51 is a servo motor. The output shafts of the left and right parts of the motor 51 respectively pass through the left and right walls of the frame 1. The second full gears 52 are welded on the output shafts of the left and right parts of the motor 51. The second gear discs 54 are rotatably connected to the left and right walls of the frame 1. The second gear discs 54 are all missing gears. The first gear discs 53 are fixedly connected to the outer walls of the second gear discs 54. The first gear discs 53 are all engaged with the adjacent second full gears 52. The guide grooves 55 are all formed on the first gear discs 53 and protrude forward. The sliding frame 56 is slidably connected to the rear part of the support 2. The guide rods 57 are installed on the left and right walls of the sliding frame 56 and slide along the adjacent guide grooves 55. The second roller 58 is rotatably connected to the sliding frame 56 and located in the support 2. The sliding frame 56 can drive the second roller 58 to slide forward and backward. The second roller 58 is located behind the first roller 3. The third full gears 59 are welded on the left and right ends of the second roller 58 and are all engaged with the adjacent second gear discs 54. The feeding port 510 is formed in the top of the support 2 and is located above the first full gear 4.

[0039] As shown in the figure, Figure 2 , Figure 6 , Figure 9 And Figure 10 The classification mechanism 6 comprises a rotating plate 61, an electric push rod 62 and a color sensor 63. The rotating plate 61 is rotatably connected between the left and right inner walls of the support 2 and is located below the first roller 3. The electric push rod 62 is installed on the inner bottom wall of the support 2. The extension part of the electric push rod 62 is connected to the rear side of the bottom wall of the rotating plate 61. The electric push rod 62 can drive the rotating plate 61 to rotate. The color sensor 63 is installed on the top wall of the support 2 and passes through the inner top wall of the support 2. The color sensor 63 is located above the position between the first roller 3 and the second roller 58. The color sensor 63 can detect whether the corn cob is mildewed according to the color of the corn cob. The color sensor 63 is electrically connected to the electric push rod 62.

[0040] The normal corn kernels are yellowish white, and the moldy corn kernels have yellow or green or black mycelium at the embryo. Therefore, people can use the color sensor 63 to detect whether the corn kernels are moldy according to the color of the corn cobs. Initially, the third spur gear 59 is engaged with the second gear disc 54. When it is necessary to screen out the moldy corn cobs, people stand at the front side of the machine frame 1, first place two specified containers on the front and rear sides of the bottom wall in the machine frame 1 respectively, so that the specified containers are located below the rotating plate 61 in front and behind respectively, and then place the corn cobs between the first roller 3 and the second roller 58 through the feeding port 510 one by one. At this time, the color sensor 63 detects the corn cobs, and transmits the data of whether the corn cobs are moldy to the electric push rod 62. When the color sensor 63 detects that the corn cobs are not moldy, the electric push rod 62 does not work, and the rotating plate 61 remains in the state of tilting from front to back, so that the corn cobs can fall from the rotating plate 61 into the specified container behind. When the color sensor 63 detects that the corn cobs are moldy, the extension part of the electric push rod 62 is elongated, and the rotating plate 61 is pushed upward, so that the rotating plate 61 rotates forward, and then the rotating plate 61 tilts from back to front, so that the corn cobs can fall from the rotating plate 61 into the specified container in front, thereby automatically screening out the moldy corn cobs, and the screening accuracy is high. Then the motor 51 is started, the output shaft of the motor 51 rotates counterclockwise to drive the second spur gear 52 to rotate counterclockwise, thereby driving the first gear disc 53 to rotate clockwise, the first gear disc 53 drives the second gear disc 54 to rotate clockwise, and then drives the second roller 58 to rotate clockwise. At this time, the first roller 3 and the second roller 58 rotate in the same direction, so that the corn cobs rotate three hundred and sixty degrees between the first roller 3 and the second roller 58, thereby enabling the color sensor 63 to detect the corn cobs in all directions, which is beneficial to improve the detection accuracy. The clockwise rotation of the first gear disc 53 drives the guide groove 55 to rotate clockwise. When the convex part of the guide groove 55 gradually rotates close to the guide rod 57, the first gear disc 53 drives the second gear disc 54 to rotate clockwise to disengage from the third spur gear 59. Then the guide rod 57 moves backward, thereby driving the second roller 58 to move backward through the sliding frame 56, so that the distance between the first roller 3 and the second roller 58 can allow the corn cobs to pass through. At this time, the detected corn cobs fall onto the rotating plate 61, and then fall into the corresponding specified container, thereby achieving the purpose of automatically transmitting the corn cobs, which is beneficial to improve the screening efficiency. When the convex part of the guide groove 55 gradually rotates away from the guide rod 57, the second gear disc 54 rotates clockwise to engage with the third spur gear 59, so that the second roller 58 moves forward, thereby driving the guide rod 57 to move forward and slide to the original position. When the screening of the corn cobs is completed, the motor 51 is turned off. Then people concentrate on processing the moldy corn cobs in the front specified container and the corn cobs not moldy in the rear specified container.

[0041] Example 2

[0042] On the basis of Example 1, Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, it also includes a feeding mechanism 7, which includes a feeding box 71, a rotating feeding cylinder 72 and a rotating rod 73. The feeding box 71 is welded to the top wall of the bracket 2, and the upper part of the feeding box 71 is tilted from back to front to facilitate the sliding of corn cobs. The upper and lower parts of the feeding box 71 are both open, and the lower part of the feeding box 71 is rotatably connected to the rotating feeding cylinder 72. The rotating feeding cylinder 72 is located below the opening of the lower part of the feeding box 71. The interior of the rotating feeding cylinder 72 is a cavity, and a material trough 74 is opened on the rotating feeding cylinder 72. The corn cobs can enter the rotating feeding cylinder 72 from the feeding box 71 through the material trough 74, and fall from the material trough 74 to between the first roller 3 and the second roller 58. A rotating rod 73 is installed at the left end of the rotating feeding cylinder 72.

[0043] Initially, the trough 74 is staggered with the lower opening of the discharge box 71. When it is necessary to screen out moldy corn cobs, people first put a plurality of corn cobs into the discharge box 71, and then rotate the rotating rod 73. The rotation of the rotating rod 73 drives the rotating material receiving cylinder 72 to rotate, thereby driving the trough 74 to rotate. When the trough 74 rotates to correspond to the lower opening of the discharge box 71, a single corn cob falls from the discharge box 71 into the rotating material receiving cylinder 72 through the trough 74. Then the rotating material receiving cylinder 72 continues to rotate, so that the corn cob is rotated out of the rotating material receiving cylinder 72 and It falls from the feed port 510 to between the first roller 3 and the second roller 58, and then continues to detect and screen the corn cobs. When the screening of a single corn cob is completed, the rotating rod 73 is rotated to allow the next corn cob to enter the rotating material receiving cylinder 72 from the discharge box 71, and be transferred from the rotating material receiving cylinder 72 to between the first roller 3 and the second roller 58, thereby achieving the purpose of intermittent transmission of corn cobs. The operation is simple and convenient. When the corn cobs do not need to be screened, stop putting the corn cobs into the discharge box 71 and stop rotating the rotating rod 73.

[0044] like Figure 2 、 Figure 9 and Figure 10 As shown, it also includes a wiping mechanism 8, which includes a connecting frame 81, a telescopic spring 82 and a wiping plate 83. The connecting frame 81 is slidably connected to the top wall of the bracket 2. The connecting frame 81 is U-shaped. Telescopic springs 82 are wound on both sides of the rear of the connecting frame 81. The front and rear ends of the telescopic spring 82 are respectively connected to the bracket 2 and the connecting frame 81. A wiping plate 83 is fixed to the front end of the connecting frame 81. The wiping plate 83 is in contact with the color sensor 63. The wiping plate 83 moves back and forth to wipe the dust on the color sensor 63.

[0045] In the process of the corn cob transmission, the dust attached to the corn cob contaminates the color sensor 63, resulting in reduced detection accuracy of the color sensor 63. When the dust on the color sensor 63 needs to be wiped, the connecting frame 81 is pulled backward, at this time the extension spring 82 is stretched, the connecting frame 81 slides backward to drive the wiping plate 83 to move backward against the color sensor 63, so that the wiping plate 83 wipes the color sensor 63, which can keep the color sensor 63 clean and help ensure the accuracy of the color sensor 63 detection. When the color sensor 63 is wiped, the connecting frame 81 is released, and the extension spring 82 resets to make the connecting frame 81 slide forward, so that the wiping plate 83 moves forward to wipe the color sensor 63 again, and the wiping effect is better.

[0046] As shown in Figure 2 , Figure 11 and Figure 12 , the pulling mechanism 9 is further included, the pulling mechanism 9 includes a connecting rod 91, a sliding rod 92, a fixed block 93, a sliding block 94 and a blocking block 95, the sliding rod 92 is slidably connected to the left side of the rear part of the support 2, two blocking blocks 95 are welded on the sliding rod 92, the sliding block 94 is slidably connected to the sliding rod 92 and located between the two blocking blocks 95, the fixed block 93 is fixedly connected to the top wall of the left guide rod 57 and connected with the sliding rod 92, the fixed block 93 can drive the sliding rod 92 to slide forward and backward, the connecting rod 91 is rotatably connected to the sliding block 94, and the connecting rod 91 is rotatably connected with the rotating rod 73.

[0047] When the guide rod 57 moves backward, the fixed block 93 moves backward to drive the sliding rod 92 to slide backward, and then the blocking block 95 moves backward, when the front blocking block 95 moves backward to contact the sliding block 94, the front blocking block 95 drives the sliding block 94 to slide backward, so as to pull the rotating rod 73 to rotate backward through the connecting rod 91, and then the rotating material cylinder 72 is rotated, and the chute 74 is further driven to rotate to correspond to the opening in the lower part of the feeding box 71, and then the corn cob falls from the feeding box 71 to the space between the first roller 3 and the second roller 58, so that the rotating rod 73 does not need to be manually rotated, the corn cob can be automatically transmitted, and the labor and time can be saved. When the guide rod 57 moves forward, the fixed block 93 moves forward to drive the sliding rod 92 to slide forward, and then the blocking block 95 moves forward, when the rear blocking block 95 moves forward to contact the sliding block 94, the rear blocking block 95 drives the sliding block 94 to slide forward, so as to pull the rotating rod 73 to rotate forward through the connecting rod 91, and then the rotating material cylinder 72 is rotated, and the chute 74 is further driven to rotate to be separated from the opening in the lower part of the feeding box 71, so that the corn cob in the feeding box 71 stops transmission.

[0048] As shown in Figure 1 and Figure 14As shown, the device further comprises a storage mechanism 10, which comprises a storage box 101, a grid plate 102 and a buckle 103, the two front and rear walls of the rack 1 are symmetrically connected with the buckle 103 in a rotating manner, and the rack 1 is symmetrically provided with the storage box 101 in front and back, each storage box 101 corresponds to two buckles 103, the buckle 103 can prevent the storage box 101 from sliding out, and the grid plate 102 is placed in each storage box 101, and the dust on the corn cob can fall into the storage box 101 through the grid plate 102.

[0049] When it is necessary to screen out moldy corn cobs, people first place two storage boxes 101 symmetrically on the rack 1, rotate the buckle 103 inward, so that the buckle 103 clamps the storage box 101, thereby fixing the storage box 101, which can prevent the storage box 101 from sliding out, when the corn cobs fall from the rotating plate 61, the corn cobs fall into the corresponding storage box 101, and the dust and impurities attached to the corn cobs fall into the bottom of the storage box 101 through the grid plate 102, when it is not necessary to screen the corn cobs, people rotate the buckle 103 outward, so that the buckle 103 is separated from the storage box 101, then the two storage boxes 101 are removed, and the corn cobs are processed, then the grid plate 102 is taken out, and the dust and impurities in the storage box 101 are cleaned, after the dust and impurities are cleaned, the grid plate 102 is put back.
