[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] like Figure 1-5 As shown, this embodiment provides a sorting device for detecting imperfect grains, including a device housing 1 for sorting grains. It also includes a sorting mechanism 2, disposed within the device housing 1. The sorting mechanism 2 includes a first enclosure 21 disposed within the device housing 1, with a coarse sieve 22 installed inside the first enclosure 21. A second enclosure 23 is also installed within the device housing 1, with a fine sieve 24 slidably installed inside the second enclosure 23. The grain to be sorted is placed within the first enclosure 21, which vibrates repeatedly up and down. The coarse sieve 22 separates large impurities, broken leaves, and straw from the grain. After sorting, the grain passes through the coarse sieve 22 and enters the second enclosure 23. The fine sieve 24 then repeatedly sorts out small impurities and particles from the grain.

[0026] To drive the movement of the coarse screen plate 22 and the fine screen plate 24, a sorting drive mechanism 3 is installed on the device housing 1 and the sorting mechanism 2. The sorting drive mechanism 3 includes a support block 31 and a connecting block 32 respectively installed on one side of the device housing 1 and the first enclosure plate 21. The connecting block 32 is slidably installed on the device housing 1. A round block 34 is installed at the bottom of the connecting block 32. A vibration spring 33 is installed on the support block 31 and the connecting block 32. A cam 35 is provided at the bottom of the round block 34. An extension plate 36 and an electric telescopic rod 37 are respectively installed at the end of the fine screen plate 24 and on the device housing 1. The electric telescopic rod 37 is detachably installed on the extension plate 36. When the cam 35 rotates, it will reciprocate to push the round block 34 upward, which will drive the connecting block 32, the first enclosure plate 21, and the coarse screen plate 22 to vibrate up and down repeatedly. The vibration spring 33 will also be repeatedly compressed, which will cause the coarse screen plate 22 to vibrate up and down repeatedly. The electric telescopic rod 37 will repeatedly extend and retract to pull the extension plate 36 and the fine screen plate 24 back and forth.

[0027] Furthermore, in order to collect the sorted grain, the sorting mechanism 2 also includes a first collection box 25 located inside the device housing 1, and a second collection box 26 located on one side of the device housing 1; the sorted grain will remain in the second enclosure 23, while fine impurities and particles will enter the first collection box 25 for collection, and the sorted grain will be collected through the second collection box 26.

[0028] Furthermore, to facilitate the replacement of collection box 25 (number one) and collection box 26 (number two), a sealing plate 27 is provided on the outer casing 1. Hinges 28 and latches 210 are provided on the outer casing 1 and the sealing plate 27. A handle 29 is installed on the sealing plate 27. By releasing the latch 210 and pulling the handle 29, the sealing plate 27 can be opened under the action of the hinges 28, allowing collection box 25 (number one) to be replaced with collection box 26 (number two).

[0029] Furthermore, in order to drive the rotation of the cam 35, the sorting drive mechanism 3 also includes a support plate 38 mounted on the other side of the device housing 1. A drive motor 39 is mounted on the support plate 38, and the cam 35 is mounted on the output end of the drive motor 39. The rotation of the drive motor 39 on the support plate 38 will drive the cam 35 to rotate.

[0030] Furthermore, to improve the stability of the movement of the first enclosure 21, a guide block 310 is installed on the other side of the first enclosure 21. The guide block 310 is slidably installed on the outer shell 1 of the device. The guide block 310 slides on the other side of the outer shell 1, which can further guide the movement of the first enclosure 21, so that the first enclosure 21 can only vibrate up and down, thereby improving the stability of the movement of the first enclosure 21.

[0031] Furthermore, in order to remove the grain from the fine sieve plate 24, the output ends of the extension plate 36 and the electric telescopic rod 37 are both equipped with disassembly blocks 311. Each set of disassembly blocks 311 has a slot 312, and a U-shaped insert 313 is engaged in the slot 312. Pulling the U-shaped insert 313 out from the set of disassembly blocks 311 directly pulls the extension plate 36 and pulls out the fine sieve plate 24. The grain on the fine sieve plate 24 will fall into the second collection box 26 for collection, and the grain on the fine sieve plate 24 can be removed.

[0032] Furthermore, to prevent the U-shaped plug 313 from falling out of the slot 312, a first magnetic block 314 is installed in the slot 312, and a second magnetic block 315 is installed at the end of the U-shaped plug 313. The first magnetic block 314 and the second magnetic block 315 are in contact with each other. Inserting the U-shaped plug 313 into the slot 312 on a set of disassembly and assembly blocks 311 can integrate the set of disassembly and assembly blocks 311. The first magnetic block 314 and the second magnetic block 315 attract each other, which can prevent the U-shaped plug 313 from falling out.

[0033] Working principle: During use, the grain to be sorted is placed inside the first enclosure 21. The drive motor 39 on the support plate 38 rotates, which drives the cam 35 to rotate. The rotation of the cam 35 pushes the round block 34 upwards and backwards, which in turn drives the connecting block 32 and the first enclosure 21 to move up and down repeatedly. The vibration spring 33 is also repeatedly compressed, which causes the coarse screen plate 22 to vibrate up and down repeatedly. This can sort out large particles, broken leaves, and straw in the grain. After sorting, the grain will pass through the coarse screen plate 22 and enter the second enclosure 23. The electric telescopic rod 37 repeatedly extends and retracts, pulling the extension plate 36 and the fine screen plate 24 back and forth, so that the grain can be sieved back and forth through the fine screen plate 24. Fine impurities and particles are sorted out. The sorted grain remains in the second enclosure 23, while the fine impurities and particles are collected in the first collection box 25. Unlock the latch 210 and pull the handle 29. With the action of the hinge 28, the sealing plate 27 can be opened and the first collection box 25 can be replaced with the second collection box 26. Then, pull the U-shaped insert 313 out from a set of disassembly blocks 311 and pull the extension plate 36 to pull out the fine sieve plate 24. The grain on the fine sieve plate 24 will fall into the second collection box 26 for collection. This completes the sorting of grain. Then, the imperfect grains are detected by the detection device to avoid affecting the detection accuracy.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
