[0028] The driving assembly includes an output motor 7 and a transmission unit. The transmission unit includes a fixed frame 8, a crank 9, a connecting rod 10, a transmission rod 11 and a mobile unit. The output motor 7 and the fixed frame 8 are both fixed on a base 12. The crank 9 is bent. A transmission column 13 is fixed to one end of the crank 9. The output shaft of the output motor 7 is fixed to the bent part of the crank 9. The other end of the crank 9 is transmission-connected to one end of the connecting rod 10.

A ratchet 14 is fixed to one end of the transmission rod 11, and an active bevel gear 15 is fixed to the other end of the transmission rod 11. The transmission rod 11 is connected to the fixed frame 8 through a fixed bearing. The ratchet 14 has M hook-shaped teeth 14-1. The rotation path of the hook at the tooth 14-1 of the ratchet 14 matches the rotation path of the transmission column 13, so that the transmission column 13 and the ratchet 14 form a ratchet mechanism.

[0029] The punching mechanism includes a punching rod 16 and k punching heads 17. The punching rod 16 is fixedly connected to the moving unit. Figure 5-6 As shown, the moving unit includes a slide bar 29 and a slider 30, the slider 30 is slidably connected to the slide bar 29, the slide bar 29 is vertically fixed by a fixing frame 8, and the slider 30 is fixed to the punching rod 16.

The punching head 17 is fixed on the punching rod 16, and the position and size of the punching head 17 and the accommodating cavity 6-1 match each other; in this embodiment, the ratchet 14 has 6 hook-shaped teeth 14-1, and the punching mechanism includes 2 punching heads 17. The rotating disk 6 is driven to rotate by the driving shaft 18, and the driving shaft 18 is provided with a driven bevel gear 19, and the active bevel gear 15 is meshed with the driven bevel gear 19; the height of the output section 3c of the conveyor belt 3 is higher than the height of the rotating disk 6, and the output section 3c of the conveyor belt 3 is located above one of the accommodating cavities 6-1, the punch head 17 is located above the other accommodating cavity 6-1, and the accommodating cavity 6-1 corresponding to the punch head 17 is located between the accommodating cavity 6-1 corresponding to the conveyor belt 3 and the accommodating cavity 6-1 corresponding to the blanking port 4-1, the chassis 4 is fixed to the base 12, the adjacent teeth 14-1 of the ratchet 14 are equally spaced, and the accommodating cavities 6-1 are evenly distributed around the center of the rotating disk 6.

[0030] The working principle of the specific driving assembly is that the output motor 7 drives the crank 9 to rotate, and the rotation of the crank 9 drives the transmission column 13 thereon to rotate. On the rotation path of the transmission column 13, the transmission column 13 can enter the hook of the tooth 14-1 of the ratchet 14, driving the ratchet 14 to rotate. After the ratchet 14 rotates a certain angle, the transmission column 13 disengages from the hook of the tooth 14-1 of the ratchet 14, and the ratchet 14 stops rotating. The rotation of the ratchet 14 can drive the transmission rod 11 to rotate, and then drive the active bevel gear 15 to rotate. The active bevel gear 15 is meshed with the driven bevel gear 19, so that the driven bevel gear 19 rotates, and the driven bevel gear 19 rotates and drives the drive shaft 18 to rotate, so that the rotating disk 6 is driven to rotate, and the rotating disk 6 rotates a certain angle, so that the accommodating chamber 6-1 rotates a certain angle to enter the next station. In this embodiment, the ratchet 14 has 6 evenly spaced hook-shaped teeth 14-1, and the rotating disk 6 rotates 60° each time. The chassis 4 is equivalent to the bottom of the rotating disk 6. The chassis 4 does not rotate, and the rotating disk 6 can be driven by the driving assembly to rotate. The output motor 7 can drive the punching mechanism to move while driving the rotating disk 6 to rotate. One end of the connecting rod 10 is driven by one end of the crank 9 to realize the eccentric rotation of the connecting rod 10 and the output motor 7. The other end of the connecting rod 10 is bound and restricted by the fixed frame 16-3. The movable range of the fixed frame 16-3 is limited by the mobile unit. The slider 30 can slide up and down on the slide bar 29. The slider 30 is fixed to the fixed frame 16-3, and the other end of the connecting rod 10 reciprocates up and down within the movable range of the fixed frame 16-3, thereby driving the punch head 17 on the punch rod 16 to reciprocate up and down, and realize the punching of the water chestnut in the accommodating chamber 6-1. According to the actual situation, the range of the reciprocating movement of the punch head 17 and the size relationship between the punch head 17 and the accommodating chamber 6-1 are set to prevent interference with the rotation of the rotating disk 6.

[0031] The accommodating cavity 6-1 corresponding to the punch head 17 is adjacent to the accommodating cavity 6-1 corresponding to the conveyor belt 3, so that after the water chestnut falls from the conveyor belt 3, it is rotated by the rotating disk 6 and punched by the punch head 17. After the rotating disk 6 rotates again, the punched water chestnut rotates to the position of the drop opening 4-1 of the bottom plate 4 and falls from the drop barrel 5 to the sorting mechanism. The drop barrel 5 is a cylindrical shape with openings at the top and bottom, and the accommodating cavity 6-1 is also a cylindrical shape that is through the top and bottom. The punch head 17 is cylindrical, and one end of the punch head 17 facing the accommodating cavity 6-1 has an arc chamfer.

[0032] There are k groups of sorting mechanisms, each blanking barrel 5 corresponds to a group of sorting mechanisms. In this embodiment, there are two groups of sorting mechanisms, which include an output unit, a detection unit and at least two groups of sorting units. The output unit includes an output belt 20 and a transmission motor. The transmission motor drives the output belt 20 to rotate. Figure 1 , 10As shown, the sorting mechanism has three groups of sorting units evenly distributed along the output belt 20, the detection unit includes an industrial camera 21, the industrial camera 21 is arranged above the output belt 20, and the industrial camera 21 faces the bottom of the blanking barrel 5, each group of sorting units includes a photoelectric sensor 22, a sorting scraper 23, a rotating rod 24 and a guide bucket 25, and the photoelectric sensor 22 and the guide bucket 25 are both arranged in front of the sorting scraper 23. The front mentioned here refers to the position along the transmission direction of the output belt 20, the position where the water chestnut arrives first is the front, and the position where it arrives later is the rear. In this embodiment, there are three groups of sorting units, and the industrial camera 21 identifies the color of the water chestnut skin, so that the water chestnuts of different maturity can be sorted according to the needs. The sorting scraper 23 is fixed on the rotating rod 24, and the rotating rod 24 is controlled to rotate by the photoelectric sensor 22, and the guide bucket 25 is tilted and arranged at the side and lower part of the output belt 20. The normal state of each sorting scraper 23 is closed, that is, the guide bucket 25 is closed parallel to the transmission direction of the output belt 20. After the industrial camera 21 identifies the color of the husk of the water chestnut, the photoelectric sensor 22 detects that the water chestnut has reached the set position, and the corresponding sorting scraper 23 is controlled by the single-chip microcomputer to open in advance. Each rotating rod 24 is driven by an independent motor. By setting the forward and reverse rotation cycle of the motor of the rotating rod 24, when the material arrives, the motor reverses, and the sorting scraper 23 is closed to drive the material into the guide bucket 25, and the water chestnut is scraped off to the corresponding collection box. By setting the horizontal movement coordinates of the output belt 20, combined with the image acquisition and recognition of the industrial camera 21, the coordinates of the water chestnut and the color of the water chestnut are detected, the water chestnut is classified, and the actions of different sorting scrapers 23 are controlled to scrape the water chestnut. When the water chestnut moves to the drop position corresponding to the color of its water chestnut with the output belt 20, the single-chip microcomputer sends a signal to control the forward and reverse rotation and movement cycle of the motor of the rotating rod 24. Each group of sorting mechanisms has a support seat for supporting the sorting mechanism, which is not drawn in the figure.

[0033] like Figure 2 As shown, the conveying assembly also includes a driving motor 26 and a pressure roller 27. The driving motor 26 is located at the output section 3c of the conveyor belt 3, and the driving motor 26 is connected to the conveyor belt 3. The pressure roller 27 is located at the lower end of the inclined section 3b of the conveyor belt 3. The pressure roller 27 is pressed above the inclined section 3b of the conveyor belt 3, and the pressure roller 27 is fixed to the moving frame 1 through an auxiliary bearing 28. The conveyor belt 3 is annular, and the dividing strip 3-1 is set on the exposed surface of the conveyor belt 3. The driving motor 26 drives the conveyor belt 3 to rotate through the rotating shaft. The pressure roller 27 presses the conveyor belt 3, so that the connection between the starting section 3a and the inclined section 3b is bent and the position of the conveyor belt 3 is fixed.

[0034] The working process of the water chestnut sorting device of the present invention is as follows:

[0035] 1. Manually put the water chestnuts into the conveyor belt 3, and the conveyor belt 3 transports the water chestnuts from a low place to a high place;

[0036] 2. The water chestnuts fall from the conveyor belt 3 into the accommodating chamber 6-1 of the switching mechanism, and the position of the accommodating chamber 6-1 with the water chestnuts is changed by the operation of the driving assembly;

[0037] 3. The accommodating cavity 6-1 with the water chestnut rotates from under the conveyor belt 3 to under a punch head 17 of the punching mechanism, and at the same time, the punching rod 16 is driven by the driving force of the driving assembly to drive the punch head 17 downward to achieve the punching of the water chestnut in the accommodating cavity 6-1;

[0038] 4. The accommodating chamber 6-1 with the punched water chestnuts is rotated from below the punch head 17 to the position of the drop opening 4-1 of the chassis 4, and the punched water chestnuts fall from the drop barrel 5 to the sorting mechanism;

[0039] 5. The water chestnuts dropped to the sorting mechanism expose the water chestnut skin and are transported forward by the output belt 20. The industrial camera 21 first identifies the water chestnuts with different skin colors, and classifies the maturity of the water chestnuts. The single-chip microcomputer controls the corresponding sorting scraper 23 to open in advance. When the photoelectric sensor 22 detects that the water chestnuts have reached the position of the sorting scraper 23, the single-chip microcomputer controls the sorting scraper 23 to rotate, retract and close, and at the same time scrape the water chestnuts into the corresponding collection box.
