[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] Depend on Figure 1-4 Provided is a rice color sorter with various particle sizes based on machine vision technology, comprising a frame 1;

[0026] Two shaft seats 4 are installed on the frame 1, and a rotating shaft 5 is rotatably arranged between the two shaft seats 4. A plurality of supporting shafts are arranged around the center of the rotating shaft 5, and a sorting barrel 6 is supported on the outside of the supporting shafts.

[0027] The sorting cylinder 6 is provided with a plurality of meshes 61 of different sizes in sections along its circumference;

[0028] The frame 1 is provided with a first discharge port 2 and a second discharge port 3, which are connected to a separation barrel 6;

[0029] The lower end of the frame 1 is equipped with a wind selection component 9;

[0030] The air selection component 9 includes a threaded shaft seat 91 arranged on the lower end surface of the frame 1, a threaded rod 93 is rotatably arranged inside the threaded shaft seat 91, a sliding shaft seat 94 is meshed outside the threaded shaft seat 93, a mounting block 95 is installed outside the sliding shaft seat 94, and a fan 98 is assembled on the mounting block 95.

[0031] In the present embodiment, in actual use, when the rice is rotated by the sorting drum 6, the rice of different particle sizes can enter the first discharge port 2 and the second discharge port 3 respectively, and the blower 98 is finally moved linearly along the stroke range of the screw rod 93 through the mutual movement cooperation of the multiple components in the air sorting assembly 9. At this time, under the blowing of the blower 98, the rice sorted in the sorting drum 6 can be blown up by the wind force, and then the impurities mixed in the rice are blown up, thereby completing the blowing of the impurities, and the blown impurities can be blown up by the wind force. The rice falls from the air separation port 62 and is collected in the air separation cylinder 97. By blowing the rice under the separation cylinder 6, the fan 98 can help separate the impurities such as dust and debris attached to the surface of the rice, so as to improve the sorting accuracy of the color sorter and reduce misjudgment. At the same time, during the color sorting process, the rice may be stuck together and affect the sorting effect. By using the fan 98 to blow the rice, the adhesion between the rice can be reduced, so that they can be better separated separately, which is convenient for the sorting operation of the color sorter.

[0032] Specifically, refer to Figure 4 The upper end surface of the mounting block 95 is rectangular and is provided with two sets of brackets, both of which are used to support the fan 98. The fan 98 is detachably mounted on the brackets by bolts.

[0033] In this embodiment, the fan 98 is fixed to the mounting block 95 by a bracket, which can provide more stable support and prevent the fan 98 from shaking or waving during operation; thereby ensuring that the fan 98 can stably blow the rice and improve the color sorting effect. At the same time, the detachable installation of the fan 98 can facilitate the maintenance and replacement of the fan 98; if the fan 98 fails or needs to be replaced, the new fan 98 can be easily disassembled and installed, reducing the time and cost of maintenance and replacement.

[0034] Specifically, refer to Figure 4 The upper end surface of the mounting block 95 supports a wind separation cylinder 97, and the upper end surface of the wind separation cylinder 97 is open. Two side limit rods 96 are arranged in the wire shaft seat 91. The two side limit rods 96 are respectively arranged on one side of the mounting block 95 and penetrate it.

[0035] In this embodiment, the side limit rod 96 can be used to laterally limit the mounting block 95, so that when the screw rod 93 rotates, the sliding shaft seat 94 can drive the mounting block 95 to move in a straight line along the travel range of the screw rod 93. At this time, the mounting block 95 can drive the fan 98 to move within the travel range of the screw rod 93, thereby blowing the bottom of the sorting drum 6 as a whole.

[0036] Specifically, refer to Figure 4 Two bearing seats 92 are mounted on the thread shaft seat 91, and both ends of the threaded rod 93 are rotatably connected to one of the bearing seats 92 respectively. One end of the threaded rod 93 passes through the bearing seat 92 and extends to the outside of the thread shaft seat 91. A motor is installed outside the thread shaft seat 91, and the output end of the motor is rotatably connected to the threaded rod 93.

[0037] In this embodiment, a motor disposed outside the screw shaft seat 91 can be used to drive the screw rod 93, thereby realizing the rotation of the screw rod 93. A bearing disposed inside the screw shaft seat 91 can provide stability for the screw rod 93 during rotation, thereby ensuring smooth rotation of the screw rod 93, thereby improving the movement smoothness of the mounting block 95.

[0038] Specifically, refer to Figure 1-3 One end of the rotating shaft 5 passes through the shaft seat 4 and is connected to a driving gear 51. The rotating shaft 5 is arranged parallel to the top of the air separation component 9. Two air separation ports 62 are arranged on the frame 1. The two air separation ports 62 are staggered with the first discharge port 2 and the second discharge port 3. The opening size of the air separation port 62 is adapted to the opening size of the air separation cylinder 97.

[0039] In the present embodiment, in actual use, the driving gear 51 provided in the preferred embodiment can be used to connect to the motor to drive the driving gear 51 to rotate. When the driving gear 51 rotates, the provided rotating shaft 5 can follow and rotate, thereby causing the rice in the sorting drum 6 to rotate. At this time, due to the opening of the mesh 61, the rice in the sorting drum 6 can rotate and gradually fall into the first discharge port 2 and the second discharge port 3. By opening the mesh 61 of varying sizes, the rice can be gradually graded and sorted. At the same time, the provided shaft seat 4 can further improve the rotation smoothness of the rotating shaft 5.

[0040] Specifically, refer to Figure 1-2 A feed trough 7 is mounted at one end of the frame 1 , a spiral feeding blade 8 is rotatably arranged in the feed trough 7 , and the feed trough 7 is connected to the sorting drum 6 .

[0041] In this embodiment, the feed trough 7 is provided to accommodate rice. When the user uses the sorting machine, the user first performs preliminary color sorting on the rice through visual technology. After the color sorting is completed, the user can pour the rice into the feed trough 7, and then drive the spiral feeding blade 8 to rotate. At this time, the spiral feeding blade 8 can spirally feed the rice poured from the feed trough 7 into the sorting drum 6 for the next step of air sorting. When the sorting drum 6 is rotating, rice of different sizes can be sorted through the mesh 61 with different aperture sizes.

[0042] The utility model is a rice color sorter with various particle sizes based on machine vision technology:

[0043] Step 1: When the user uses the sorting machine, the user first performs preliminary color sorting of the rice through visual technology. After the color sorting is completed, the user can pour the rice into the feed trough 7, and then drive the spiral feeding blade 8 to rotate. At this time, the spiral feeding blade 8 can spirally feed the rice poured from the feed trough 7 into the sorting cylinder 6;

[0044] Step 2: After the rice is driven by the spiral feeding blade 8 and enters the sorting drum 6, the user drives the driving gear 51 to rotate. At this time, the sorting drum 6 is driven by the driving gear 51 to rotate accordingly. When the sorting drum 6 rotates, the rice entering the sorting drum 6 can be continuously rotated. Through the first discharge port 2 and the second discharge port 3, the rice in the sorting drum 6 can enter the first discharge port 2 and the second discharge port 3 through the meshes 61 with different apertures, respectively. At this time, the rice can be sorted.

[0045] Step 3: When the rice is rotated by the sorting drum 6 so that the rice with different particle sizes can enter the first discharge port 2 and the second discharge port 3 respectively, the user can drive the screw 93 to rotate, cooperate with the rotation of the two bearing seats 92, and the linear limit of the side limit rod 96, so that the sliding shaft seat 94 engaged with the outside of the screw 93 can drive the mounting block 95 to move linearly along the stroke range of the screw 93. At this time, the user controls the movement of the mounting block 95, cooperates with the installation of the fan 98, and finally enables the fan 98 to move linearly along the stroke range of the screw 93. At this time, under the blowing of the fan 98, the rice sorted in the sorting drum 6 can be blown up by the wind force, and then the impurities mixed in the rice are blown up, thereby completing the blowing of the impurities, and the blown impurities can fall through the air selection port 62, and at the same time fall into the air selection drum 97 to be collected.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
