During the sorting of different varieties of grains, different models of sorting plates need to be replaced, and the operation is cumbersome, which will affect the efficiency of intelligent grain sorting.

[0026] A method for an intelligent grain sorting system. When the intelligent grain sorting system is in use, it needs to use the method of the intelligent grain sorting system, including the following steps:

[0027] S1: Install the sorting plate inside the sorting frame through the support plate, elastic components and connecting bolts, and place one side of the sorting plate below the spectral sorting frame. At the same time, make the sorting plate form a small slope. Then connect the vibration component to one side of the sorting plate through the support frame. The vibration component can be used to drive the sorting plate to vibrate at different frequencies. Then, only need to install the adjustment plate below the sorting plate through two installation rails. Multiple rows of corresponding sieve holes are opened on both the adjustment plate and the sorting plate. One side of the adjustment plate is connected to the telescopic component through the movable buckle. The telescopic movement of the telescopic component can make the sieve holes on the sorting plate and the adjustment plate misaligned, so as to realize the rapid adjustment of the sieve hole size. And the two stabilizing rods on the support frame are connected to one side of the adjustment plate through the movable buckle;

[0028] S2: At the top of the sorting frame above the sorting plate, install the intelligent scanning component through the second mounting frame, and install the multispectral sorting component through the first mounting frame at the top of the sorting frame above the spectral sorting frame. Use the intelligent scanning component to identify the grains on the sorting plate, and at the same time cooperate with the multispectral sorting component to classify the grains. Then, the controller that controls the telescopic component can control the telescopic component to work and adjust the sieve hole size. In this process, the intelligent scanning component can record the size data of the sieve hole before and after adjustment;

[0029] S3: In the actual use process, first put the grains to be sorted into the spectral sorting frame through the feeding frame and the speed reducing component. Since there is a slope on the side of the spectral sorting frame opposite to the multispectral sorting component, the grains will slowly move downward under the influence of gravity. In this process, the multispectral sorting component can accurately identify the variety, plumpness, mildew situation and impurity type of the grains by using the differences in the absorption and reflection characteristics of different types of grains and impurities for each band of spectrum through multispectral fusion analysis. The size and dimensions of the grains identified by the multispectral sorting component provide activity parameters for the telescopic component, so as to drive the adjustment plate to move by the telescopic component and adjust the sieve hole size, so that the grains sorted by the multispectral sorting component are sorted by the sorting plate. In this process, the vibration component works to provide a corresponding frequency of vibration for the sorting plate to assist the grains to move between the two partition bars above the sorting plate. The grains that do not meet the requirements will fall into the lower guide plate through the sieve holes and be discharged, while the grains that meet the requirements will be discharged through the guiding frame. During the sorting process of the grains on the sorting plate, the intelligent scanning component monitors the sorting process in real time and provides data for sieve hole adjustment, and sends a signal in time if an abnormality occurs.

[0030] Compared with the related technology, the intelligent grain sorting system and its method provided by the present invention have the following

[0031] Beneficial effects:

At the same time, the sorting plate forms a small slope. Then, the vibration member is connected to one side of the sorting plate through a support frame. By using the vibration member, the sorting plate can be driven to vibrate at different frequencies. After that, only the adjusting plate needs to be installed below the sorting plate through two installation rails. Multiple rows of corresponding sieve holes are provided on both the adjusting plate and the sorting plate. One side of the adjusting plate is connected to the telescopic member through a movable buckle. The telescopic movement of the telescopic member can make the sieve holes on the sorting plate and the adjusting plate misaligned, thereby realizing the rapid adjustment of the sieve hole size. Moreover, the two stabilizing rods on the support frame are connected to one side of the adjusting plate through a movable buckle, which can increase the stability of the adjustment of the adjusting plate. At the top of the sorting frame and above the sorting plate, an intelligent scanning member is installed through a second mounting frame, and the multi-spectral sorting member is installed on the top of the sorting frame and above the spectroscopy sorting frame through a first mounting frame. By using the intelligent scanning member to identify the grains on the sorting plate and cooperating with the multi-spectral sorting member to classify the grains, the controller for controlling the telescopic member can control the telescopic member to work and adjust the sieve hole size. In this process, the intelligent scanning member can record the size data of the sieve holes before and after adjustment. Through this design, different varieties of grains can be sorted intelligently and quickly, and the sieve hole size can be quickly adjusted during the sorting process, making it applicable to different qualities of grains, which is beneficial to improving the intelligent sorting effect of different quality grains.

[0058] A method for an intelligent grain sorting system. When the intelligent grain sorting system is in use, it needs to use the method of the intelligent grain sorting system, including the following steps:

[0059] S1: Install the sorting plate 17 inside the sorting frame 9 through the support plate 25, elastic component 26 and connecting bolts 27, and make one side of the sorting plate 17 be under the spectral sorting frame 20, and at the same time make the sorting plate 17 form a small slope. Then connect the vibration component 32 to one side of the sorting plate 17 through the support frame 23. The vibration component 32 can be used to drive the sorting plate 17 to vibrate at different frequencies. Then only need to install the adjusting plate 28 under the sorting plate 17 through two installation rails 30. Multiple rows of corresponding sieve holes 4 are opened on both the adjusting plate 28 and the sorting plate 17. One side of the adjusting plate 28 is connected to the telescopic component 21 through a movable buckle 31. The telescopic movement of the telescopic component 21 can make the sieve holes 4 on the sorting plate 17 and the adjusting plate 28 be misaligned, so as to achieve rapid adjustment of the sieve hole size, and the two stabilizing rods 22 on the support frame 23 are connected to one side of the adjusting plate 28 through the movable buckle 31.

[0060] S2: Above the sorting plate 17 at the top of the sorting frame 9, an intelligent scanning component 14 is installed through the second mounting frame 15, and the multi-spectral sorting component 12 is installed above the spectral sorting frame 20 at the top of the sorting frame 9 through the first mounting frame 13. The intelligent scanning component 14 is used to identify the grains on the sorting plate 17, and at the same time cooperate with the multi-spectral sorting component 12 to classify the grains. The controller of the telescopic component 21 can be used to control the telescopic component 21 to work and adjust the size of the sieve holes 4. In this process, the intelligent scanning component 14 can record the size data of the sieve holes 4 before and after adjustment.

[0061] S3: During actual use, the grains to be sorted first enter the spectral sorting rack 20 through the feeding frame 10 and the speed-reducing component 11. Since there is a slope on the opposite side of the spectral sorting rack 20 and the multi-spectral sorting component 12, the grains will slowly move downward under the influence of gravity. During this process, the multi-spectral sorting component 12 can accurately identify the variety, plumpness, mildew condition, and impurity type of the grains by using the differences in the absorption and reflection characteristics of different types of grains and impurities for each band of the spectrum through multi-spectral fusion analysis. The size and dimensions of the grains identified by the multi-spectral sorting component 12 provide movement parameters for the telescopic component 21, so as to drive the adjusting plate 28 to move by using the telescopic component 21 and adjust the size of the sieve holes 4, enabling the grains identified and sorted by the multi-spectral sorting component 12 to be sorted by the sorting plate 17. During this process, the vibration component 32 works to provide a vibration at a corresponding frequency for the sorting plate 17 to assist the grains in moving between the two partition bars 3 above the sorting plate 17. The grains that do not meet the requirements will fall through the sieve holes 4 onto the lower guide plate 2 and be discharged, while the grains that meet the requirements will be discharged through the guiding frame 18. During the sorting process of the grains on the sorting plate 17, the intelligent scanning component 14 monitors the sorting process in real time and provides data for adjusting the sieve holes 4, and sends a signal in a timely manner if an abnormality occurs.

[0062] The working principle of the intelligent grain sorting system and method provided by the present invention is as follows:

[0063] The sorting plate 17 is installed inside the sorting frame 9 through the support plate 25, the elastic member 26 and the connecting bolt 27, and one side of the sorting plate 17 is displaced below the spectral sorting frame 20. At the same time, the sorting plate 17 forms a small slope. Then, the vibration member 32 is connected through the support frame 23 and one side of the sorting plate 17. The vibration member 32 can be used to mobilize the sorting plate 17 to vibrate at different frequencies. Then, only the adjusting plate 28 needs to be installed below the sorting plate 17 through two mounting rails 30. Multiple rows of corresponding screening holes 4 are provided on both the adjusting plate 28 and the sorting plate 17. One side of the adjusting plate 28 is connected to the telescopic member 21 through the movable buckle 31. The telescopic movement of the telescopic member 21 can misalign the screening holes 4 on the sorting plate 17 and the adjusting plate 28, so as to realize the rapid adjustment of the size of the screening holes. The two stabilizing rods 22 on the support frame 23 are connected to one side of the adjusting plate 28 through the movable buckle 31, which can increase the stability of the adjustment of the adjusting plate 28. Above the sorting plate 17 at the top of the sorting frame 9, the intelligent scanning member 14 is installed through the second mounting frame 15, and the multi-spectral sorting member 12 is installed above the spectral sorting frame 20 at the top of the sorting frame 9 through the first mounting frame 13. The intelligent scanning member 14 is used to identify the grains on the sorting plate 17, and at the same time, the multi-spectral sorting member 12 is used to classify the grains. The controller for controlling the telescopic member 21 can control the telescopic member 21 to work to adjust the size of the screening holes 4. In this process, the intelligent scanning member 14 can record the size data of the screening holes 4 before and after adjustment. In the actual use process, the grains to be sorted first enter the spectral sorting frame 20 through the feeding frame 10 and the speed-reducing component 11. Since there is a slope on the opposite side of the spectral sorting frame 20 and the multi-spectral sorting member 12, the grains will slowly move downward under the influence of gravity. In this process, the multi-spectral sorting member 12 can accurately identify the variety, plumpness, mildew condition and impurity type of the grains by using the differences in the absorption and reflection characteristics of different types of grains and impurities for each band of the spectrum through multi-spectral fusion analysis. The size and dimensions of the grains identified by the multi-spectral sorting member 12 provide movement parameters for the telescopic member 21, so as to drive the adjusting plate 28 to move by the telescopic member 21 and adjust the size of the screening holes 4, so that the grains identified and sorted by the multi-spectral sorting member 12 are sorted by the sorting plate 17. In this process, the vibration member 32 works to provide a corresponding frequency of vibration for the sorting plate 17 to assist the grains to move between the two partition bars 3 above the sorting plate 17. The grains that do not meet the requirements will fall through the screening holes 4 onto the lower guide plate 2 and be discharged, while the grains that meet the requirements will be discharged through the guide frame 18. During the sorting process of the grains on the sorting plate 17, the intelligent scanning member 14 monitors the sorting process in real time and provides data for the adjustment of the screening holes 4, and sends out a signal in time if an abnormality occurs.

At the same time, the sorting plate 17 forms a small slope. Then, the vibration member 32 is connected to one side of the sorting plate 17 through the support frame 23. By using the vibration member 32, the sorting plate 17 can be driven to vibrate at different frequencies. After that, only the adjusting plate 28 needs to be installed below the sorting plate 17 through two mounting rails 30. Multiple rows of corresponding screening holes 4 are provided on both the adjusting plate 28 and the sorting plate 17. One side of the adjusting plate 28 is connected to the telescopic member 21 through the movable buckle 31.

The positions of the cleaning frame 41 and the nozzles 24 correspond to each other, which is convenient for blowing the lighter grains into the cleaning frame 41.

10. A method for an intelligent grain sorting system, characterized in that, An intelligent grain sorting system as described in any one of claims 1-9, and a method for using the intelligent grain sorting system is required during use, including the following steps: S1: Install the sorting plate inside the sorting frame through a support plate, elastic components, and connecting bolts, and place one side of the sorting plate below the displacement spectroscopy sorting frame. At the same time, form a small slope for the sorting plate. Then connect the vibration component to one side of the sorting plate through a support frame. The vibration component can be used to drive the sorting plate to vibrate at different frequencies. Then, simply install the adjustment plate below the sorting plate through two installation rails. Multiple rows of corresponding sieve holes are provided on both the adjustment plate and the sorting plate. One side of the adjustment plate is connected to the telescopic component through a movable buckle. The telescopic movement of the telescopic component can cause the sieve holes on the sorting plate and the adjustment plate to be misaligned, thereby achieving rapid adjustment of the sieve hole size. And two stabilizing rods on the support frame are connected to one side of the adjustment plate through movable buckles; S2: At the top of the sorting frame and above the sorting plate, an intelligent scanning component is installed through a second mounting frame, and the multi-spectral sorting component is installed at the top of the sorting frame and above the spectroscopy sorting frame through a first mounting frame. The intelligent scanning component is used to identify the grains on the sorting plate. At the same time, in cooperation with the multi-spectral sorting component to classify the grains, the controller that controls the telescopic component can control the telescopic component to work to adjust the sieve hole size. During this process, the intelligent scanning component can record the size data of the sieve holes before and after adjustment; S3: During actual use, first pass the grains to be sorted through the feeding frame and the speed reduction component into the spectroscopy sorting frame. Since there is a slope on the side of the spectroscopy sorting frame opposite to the multi-spectral sorting component, the grains will slowly move downward under the influence of gravity. During this process, the multi-spectral sorting component can accurately identify the variety, plumpness, mildew condition, and impurity type of the grains by using the differences in the absorption and reflection characteristics of different types of grains and impurities for each band of the spectrum through multi-spectral fusion analysis. The size and dimensions of the grains identified by the multi-spectral sorting component provide movement parameters for the telescopic component. Thus, the telescopic component drives the adjustment plate to move, adjusting the sieve hole size, so that the grains identified and sorted by the multi-spectral sorting component are sorted by the sorting plate. During this process, the vibration component works to provide a corresponding frequency of vibration for the sorting plate, assisting the grains to move between the two partition bars above the sorting plate. The grains that do not meet the requirements will fall through the sieve holes onto the guide plate below and be discharged, while the grains that meet the requirements will be discharged through the guiding frame. During the sorting process of the grains on the sorting plate, the intelligent scanning component monitors the sorting process in real time and provides data for sieve hole adjustment, and sends a signal in a timely manner if an abnormality occurs.
