Description

Technical Field

[0001] This utility model relates to the field of rice sorting technology, and in particular to a rice sorting machine with grading function. Background Technology

[0002] Rice color sorting technology involves capturing images of rice using industrial cameras and analyzing features such as color, shape, and texture using algorithms to identify and separate impurities that differ significantly from normal rice (such as stones, moldy grains, and discolored grains). Rice color sorting technology has the advantage of high sorting accuracy.

[0003] Existing rice sorting machines, after color sorting to remove impurities, can only output two types of rice: good quality and impurities. For rice processing, broken rice grains also need to be sorted out to ensure the quality of the finished rice product. Current technology performs color sorting and grading in two separate steps, adding an intermediate transfer step, which reduces the efficiency of rice sorting. Therefore, this invention proposes a rice sorting machine with grading capabilities to address the shortcomings of existing technologies. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a rice sorting machine with grading function. By setting a rotary table, the rice can be rotated and sorted by the sorting mechanism. The sorted good rice directly enters the grading mechanism below through the discharge notch. After being graded by multiple groups of grading screens, the good rice is discharged directly, eliminating intermediate transfer steps and effectively improving the quality and efficiency of rice sorting.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A further improvement is that the rotary table includes a base plate, a frustum plate, and a main shaft. The main shaft is rotatably mounted on the top of the base plate, and the frustum plate is mounted on the upper end of the main shaft. The main shaft is driven by a rotary motor.

[0009] A further improvement is that a hopper is installed on the baffle, and the top of the circular platform between the enclosure and the central platform forms an operating channel, with the lower end of the hopper's outlet located inside the operating channel.

[0010] A further improvement is that a flat material plate is provided in the operating channel on one side of the hopper, and the flat material plate and the enclosure can be detached and installed.

[0011] A further improvement is that the graded outer shell includes a base, a vibration motor, a spring, and a housing. The housing is slidably mounted on the top of the base. One end of the housing is connected to the base via a spring. The vibration motor is mounted on the base, and the output end of the vibration motor contacts the outer wall of one end of the housing.

[0019] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] according to Figure 1-3 As shown in the figure, this embodiment proposes a rice sorting machine with grading function, including a rotary table 1, a enclosure 2, a central platform 3, a sorting mechanism, and a grading mechanism. The enclosure 2 is provided on the outer side of the rotary table 1, and the central platform 3 is located at the center of the rotary table 1. The enclosure 2 has a discharge notch 4, and a baffle 5 is provided on the inner wall of the enclosure 2 at the discharge notch 4. One end of the baffle 5 is connected to the outer wall of the central platform 3. The sorting mechanism includes an industrial camera 6 and a negative pressure suction pipe 7. A first mounting beam 8 and a second mounting beam 9 are provided above the enclosure 2 and the central platform 3. The first mounting beam 8 is equipped with the industrial camera 6, and three sets of the industrial cameras 6 are arranged in a row. The second... The mounting beam 9 is provided in three sets, and each of the three sets of second mounting beams 9 is equipped with a negative pressure suction pipe 7. The three sets of negative pressure suction pipes 7 are staggered. In this utility model, the top of the central platform 3 is provided with a receiver and a controller. The data output end of the three sets of industrial cameras 6 is electrically connected to the input end of the receiver. The output end of the receiver is connected to the controller. The controller is electrically connected to the valve of the negative pressure suction pipe 7. The grading mechanism is provided below the discharge notch 4. The grading mechanism includes a grading shell 10 and a grading sieve plate 11. The grading shell 10 is provided with a grading sieve plate 11. The grading sieve plate 11 is provided in at least two sets, and the sieve aperture of the multiple sets of grading sieve plates 11 decreases from top to bottom.

[0021] When the rice sorting machine with grading function of this utility model is working, the rice to be sorted is fed onto the rotary table 1 between the enclosure 2 and the central platform 3. During the rotation of the rotary table 1, the rice is moved to the sorting mechanism. First, the rice at different positions is visually sorted by three sets of industrial cameras 6. The sorting results are transmitted to the controller through the receiver. The controller controls the activation of the negative pressure suction pipe 7 at the corresponding position according to the visual sorting results of the corresponding industrial camera 6. The negative pressure suction pipe 7 is connected to the external negative pressure mechanism, and impurities are adsorbed out through negative pressure adsorption. Good quality rice is moved to the discharge notch 4 by the rotary table 1 and discharged into the grading mechanism under the action of the baffle 5 for good quality grading, separating whole rice and broken rice.

[0022] The rotary table 1 includes a base plate 101, a frustum plate 102, and a main shaft 103. The main shaft 103 is rotatably mounted on the top of the base plate 101, and the frustum plate 102 is mounted on the upper end of the main shaft 103. The main shaft 103 is driven by a rotary motor 104. When the rotary table 1 of this invention is in operation, the rotary motor 104 is started to drive the main shaft 103 to rotate, thereby driving the frustum plate 102 to rotate synchronously.

[0023] A hopper 12 is installed on the baffle 5. The top of the frustum plate 102 between the enclosure 2 and the central platform 3 forms a running channel. The discharge port at the lower end of the hopper 12 is located inside the running channel. The hopper 12 in this invention enables uniform feeding into the running channel.

[0024] A flat material plate 13 is provided in the operating channel on one side of the hopper 12. The flat material plate 13 is detachably installed from the enclosure 2. By setting the flat material plate 13, the rice located in the operating channel can be leveled, and the leveled rice is easier for the subsequent industrial camera 6 to perform precise visual recognition and sorting.

[0025] The grading housing 10 includes a base 1001, a vibration motor 1002, a spring 1003, and a housing 1004. The housing 1004 is slidably mounted on the top of the base 1001. One end of the housing 1004 is connected to the base 1001 via the spring 1003. The vibration motor 1002 is mounted on the base 1001, and the output end of the vibration motor 1002 contacts the outer wall of one end of the housing 1004. When the grading mechanism of this invention performs the grading operation of high-quality rice, the vibration motor 1002 is activated to cause the housing 1004 to vibrate. In this invention, both the housing 1004 and the multi-component grading sieve plate 11 are inclined, and the outlet positions of the multi-component grading sieve plate 11 are different. Through vibration, broken rice grains in the high-quality rice are screened out, thus achieving grading.

[0026] The outer wall of the enclosure 2 is provided with a support column 14, which is connected to the top of the base plate 101.

[0027] This invention utilizes a rotary table 1 to move rice through a sorting mechanism for sorting. The sorted rice then enters the grading mechanism below through the discharge notch 4. The rice undergoes multi-stage grading via multi-group grading sieves 11 before being discharged, eliminating intermediate transfer steps and effectively improving rice sorting quality and efficiency. The sorting mechanism consists of an industrial camera 6 and three sets of negative pressure suction pipes 7, which are staggered. This staggered arrangement allows for precise impurity removal, avoiding incorrect suction and effectively improving impurity removal accuracy.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
