[0002] As a common dried fruit, betel nut is a key link to guarantee product quality and commercial value in the process of betel nut processing. Betel nuts with uniform size not only have better appearance and quality, but also are convenient for subsequent deep processing and packaging. At present, the sorting equipment commonly used in the industry is based on the principle of vibrating screen or roller screen separation. By setting different specifications of screen holes, betel nuts smaller than the hole diameter are allowed to fall, so as to realize size grading. However, this kind of traditional sorting method has inherent defects. Since the shape of betel nut is mostly irregular oval, it is easy to tilt during vibration or rolling, which cannot guarantee that each betel nut can smoothly pass through the screen hole in the same form. This will lead to the betel nuts belonging to small size grade being incorrectly divided into large size grade, resulting in inaccurate sorting results and poor product consistency. SUMMARY

The implementation conditions used in the embodiments can be further adjusted according to the specific conditions of the manufacturer, and the implementation conditions not mentioned are usually the conditions in the conventional experiments.

[0023] Since the betel nuts are mostly irregularly oval in shape, they are prone to tilt during vibration or rolling, which cannot guarantee that each betel nut passes through the screening hole smoothly in the same form, which will lead to the betel nuts belonging to the small size grade being incorrectly divided into the large size grade, resulting in inaccurate sorting results and poor product consistency.

[0025] As Figure 4 With Figure 5As shown, the two sides of the first flexible belt 8 and the front and back sides of the second flexible belt 9 are fixed with a plurality of flexible blocks 11 distributed at intervals. Take the upper flexible block 11 as an example. The upper flexible block 11 is higher than the height of the upper arc surface of the first flexible belt 8 and the upper arc surface of the second flexible belt 9. During the differential movement of the first flexible belt 8 and the adjacent second flexible belt 9, the upper flexible block 11 of the first flexible belt 8 and the upper flexible block 11 of the adjacent second flexible belt 9 relatively displace, the betel nut is adjusted, the betel nut is pushed to the state that the long side is parallel to the first flexible belt 8, so that the betel nut enters between the first flexible belt 8 and the adjacent second flexible belt 9, and the flexible block 11 is deformed under pressure and passes through the adjacent extrusion frame 10.

[0026] The specific working principle is as follows:

[0027] When the operator needs to use the device to sort the betel nut, the betel nut is placed on all the first flexible belt 8 and all the second flexible belt 9, and then the first motor 2 and the second motor 5 are started through the control terminal. The output shaft of the first motor 2 drives the first rotating roller 3 to rotate, the first rotating roller 3 drives the second rotating ring 7 to rotate through the second flexible belt 9, the output shaft of the second motor 5 drives the second rotating roller 6 to rotate, and the second rotating roller 6 drives the first rotating ring 4 to rotate through the first flexible belt 8. Because the rotating speed of the output shaft of the first motor 2 is greater than that of the output shaft of the second motor 5, the rotating speed of the second flexible belt 9 is greater than that of the first flexible belt 8, and all the first flexible belt 8 and all the second flexible belt 9 jointly drive the betel nut to move to the right.

[0028] During the movement of the betel nut to the right, all the first flexible belt 8 and all the second flexible belt 9 drive the flexible blocks 11 thereon to move. If the long side of the betel nut is parallel to the first flexible belt 8, the betel nut is driven to move to the right until the betel nut falls down between the first flexible belt 8 and the adjacent second flexible belt 9. If the betel nut is placed obliquely, the betel nut cannot enter between the first flexible belt 8 and the adjacent second flexible belt 9, then the corresponding two flexible blocks 11 relatively move and jointly extrude the two ends of the long side of the betel nut, so that the betel nut is adjusted, the long side of the betel nut is parallel to the first flexible belt 8 and enters between the first flexible belt 8 and the adjacent second flexible belt 9, so as to reduce the probability that the betel nut cannot pass through between the first flexible belt 8 and the adjacent second flexible belt 9 due to the oblique state during the movement, thereby reducing the probability that the small-size betel nut is mixed into the large-size betel nut after the betel nut is sorted, improving the consistency of the size of the betel nut after the betel nut is sorted, and further ensuring the quality of the sorted betel nut.

[0029] In the process of moving the betel nuts to the right, the distance between the first flexible belt 8 and the adjacent second flexible belt 9 gradually increases from left to right, so the distance between the first flexible belt 8 and the adjacent second flexible belt 9 through which the betel nuts pass gradually increases, and the betel nuts fall down at the corresponding position, and the operator collects the falling betel nuts, thereby realizing the sorting of the betel nuts. When the betel nuts are sorted, the operator turns off the first motor 2 and the second motor 5 through the control terminal.

[0030] In the embodiment 2, the first connecting frame 12 and the second connecting frame 13 are fixedly connected with the collecting frame 14. Figure 2 、 Figure 3 In the embodiment 2, the first connecting frame 12 and the second connecting frame 13 are fixedly connected with the collecting frame 14. Figure 6 As shown in the embodiment 2, the first connecting frame 12 and the second connecting frame 13 are fixedly connected with the collecting frame 14, and the collecting frame 14 is fixedly connected with the buffer pad 15. After the betel nuts fall down through the first flexible belt 8 and the adjacent second flexible belt 9, the betel nuts fall on the buffer pad 15, and the buffer pad 15 is used for buffering the falling betel nuts to reduce the probability of falling and breaking of the betel nuts, thereby ensuring the quality of the sorted betel nuts. The buffer pad 15 is provided with a plurality of through holes 16 which are distributed at intervals, and the width of the through holes 16 gradually increases from left to right. The maximum width of the through holes 16 is smaller than the minimum width between the first flexible belt 8 and the adjacent second flexible belt 9. The through holes 16 are used for filtering the betel nut debris to reduce the amount of debris mixed in the sorted betel nuts, thereby improving the quality of the sorted betel nuts.

[0031] In the embodiment 3, the first connecting frame 12 and the second connecting frame 13 are fixedly connected with the collecting frame 14. Figure 3 In the embodiment 3, the first connecting frame 12 and the second connecting frame 13 are fixedly connected with the collecting frame 14. Figure 6As shown, the front and rear sides of the collection frame 14 are provided with a plurality of screening holes 17 distributed at intervals, the left and right widths of the screening holes 17 are smaller than the length of the long side of the betel nut, the left and right widths of the screening holes 17 are greater than the length of the short side of the betel nut, the screening holes 17 are used for screening the complete and broken betel nuts, the rack 1 is provided with a third motor 18 electrically connected with the control terminal, the output shaft of the third motor 18 is connected with the collection frame 14 through a transmission member, wherein the transmission member is composed of two pulleys and a belt, the two pulleys are fixedly connected with the output shaft of the third motor 18 and the collection frame 14 respectively, in the above embodiment, the first connecting frame 12 and the second connecting frame 13 are fixedly connected with the collection frame 14, in the present embodiment, the first connecting frame 12 and the second connecting frame 13 are rotatably connected with the collection frame 14, the collection frame 14 is fixedly connected with a plurality of stop blocks 19 which are equal in number to the screening holes 17, the stop blocks 19 are located at the adjacent screening holes 17, the stop blocks 19 are provided with grooves 20 which are in communication with the adjacent screening holes 17, the flow areas of the screening holes 17 and the grooves 20 increase successively from left to right, the front and rear lengths of the grooves 20 are equal to the left and right widths of the adjacent screening holes 17, that is, the front and rear lengths of the grooves 20 are smaller than the length of the long side of the normal betel nut, after the betel nuts fall on the buffer pad 15, the third motor 18 is started by the control terminal, the output shaft of the third motor 18 drives the collection frame 14 to reciprocatingly rotate through the transmission member, the collection frame 15 drives the buffer pad 15 to reciprocatingly rotate, so that the betel nuts move forward and backward on the buffer pad 15, when the betel nuts move to a screening hole 17, if the betel nuts are not complete (that is, the betel nuts are defective), the betel nuts will directly pass through the screening hole 17 and the groove 20, so as to screen out the defective betel nuts, if the betel nuts are complete, the betel nuts are stopped outside the screening hole 17 or inserted into the screening hole 17, since the front and rear depths of the grooves 20 are smaller than the length of the long side of the betel nut, the complete betel nuts cannot pass through the grooves 20 and are discharged, so that the complete betel nuts and the defective betel nuts are screened, thereby improving the effect of betel nut sorting and guaranteeing the quality of the collected betel nuts, when the betel nuts are sorted, the third motor 18 is turned off by the control terminal, and the sorted betel nuts are collected separately.
