[0037] Potatoes are also called potatoes. In the production process of potatoes, it is often necessary to sort potatoes according to their size. In the process of manual sorting, workers sort potatoes according to their own subjective judgment and experience. The effect of potato sorting depends on the experience of workers. There is a big difference in the size of potatoes sorted by different workers. When sorting potatoes, multiple workers often cooperate. When sorting potatoes, the human operation error is large, which makes the difference between potatoes sorted to the same specification large.

[0038] The invention provides a potato sorting machine.

[0039] See also Figure 1 and Figure 2 In one embodiment of the present invention, the potato sorting machine comprises:

[0040] A filling box 1, wherein the filling box 1 has a filling slot 11 therein and a filling port on the top side of the filling box 1;

[0041] A sorting box 2 is connected to the filling box 1. The sorting box 2 has a sorting slot 21 therein. The sorting slot 21 is connected to the filling slot 11. The bottom side of the sorting box 2 has a discharge port. The filling box 1 and the sorting box 2 are arranged in sequence along a first direction.

[0042] A feeding assembly 3, used for feeding the potatoes in the filling slot 11 into the sorting slot 21; and

[0043] At least three sorting elements 4 are arranged in the sorting slot 21. At least three sorting elements 4 are arranged in sequence along the first direction. A sorting gap 41 is provided between two adjacent sorting elements 4. The sorting gap 41 is used for potatoes to pass through. The width of the sorting gap 41 between two adjacent sorting elements 4 gradually increases along the first direction.

[0044] The technical solution of the present invention is to set up the filling box 1. After the potatoes are loaded into the filling slot 11, the feeding assembly 3 is controlled to sequentially feed the potatoes from the filling slot 11 into the sorting slot 21 along the first direction. The potatoes sequentially pass through the sorting gap 41 along the first direction. When the diameter of the potatoes is smaller than the sorting gap 41, the potatoes can fall from the sorting gap 41. When the diameter of the potatoes is larger than the sorting gap 41, the potatoes pass through the sorting gap 41 and move to the next sorting gap 41. The potatoes can be sequentially sorted through the sorting gap 41. By directly comparing the width of the sorting gap 41 and the diameter of the potatoes, the human operation error in the potato sorting process is reduced, and the problem of large differences between potatoes sorted to the same specification is improved as a whole.

[0045] The feeding assembly 3 includes a push plate 31 and an electric push rod 321, wherein the push plate 31 is slidably disposed in the filling box 1, the housing of the electric push rod 321 is mounted on the filling box 1, and the output shaft of the electric push rod 321 is connected to the push plate 31, and the electric push rod 321 is located at a side of the push plate 31 away from the sorting box 2. By controlling the electric push rod 321, the push plate 31 can be moved closer to or away from the sorting box 2, thereby pushing the potatoes in the filling slot 11 into the sorting slot 21.

[0046] In the embodiment of the present application, the feeding assembly 3 includes:

[0047] A push plate 31 is slidably mounted in the loading slot 11; and

[0048] The cylinder 32 is connected to the filling box 1 , and has a push rod 321 that is movable along a first direction. The push rod 321 is connected to a side of the push plate 31 that is away from the sorting box 2 .

[0049] By starting the air cylinder 32 , the push rod 321 can push the push plate 31 close to the sorting slot 21 , thereby withdrawing the potatoes in the filling slot 11 into the sorting slot 21 .

[0050] The feeding assembly 3 further includes a pneumatic motor 33, the cylinder 32 has an air inlet 322, and the air outlet of the pneumatic motor is connected to the air inlet 322. When the pneumatic motor 33 is started, the compressed air can be fed into the cylinder 32 through the air inlet 322, thereby pushing the push plate 31 to move and approach the sorting box 2.

[0051] See also Figure 1 , Figure 2 and Figure 3 The feeding assembly 3 further includes a return spring 34, which is located on the side of the push plate 31 away from the sorting box 2. One end of the return spring 34 is connected to the push plate 31, and the other end is connected to the inner wall of the filling box 1. When the cylinder 32 stops pushing the push plate 31, and the gas in the cylinder 32 is discharged through the air outlet 323, the return spring 34 deforms and contracts, which can drive the push plate 31 away from the sorting box 2, increase the distance between the push rod 321 and the sorting box 2, and after the potatoes are loaded into the filling slot 11, it is convenient for the push plate 31 to push the next batch of potatoes into the sorting slot 21.

[0052] See also Figure 2 and Figure 4A mounting frame 5 is provided on one side of the filling box 1 away from the sorting box 2. The pneumatic motor 33 and the cylinder 32 are both mounted on the mounting frame 5, and the push rod 321 drives the side wall of the filling box 1.

[0053] The cylinder 32 further has an air outlet 323 , and a solenoid valve is disposed at the air outlet 323 of the cylinder 32 .

[0054] The mounting frame 5 is also provided with a distribution box 51, which is electrically connected to the pneumatic motor 33. The distribution box 51 has a three-phase power access slot 511. By means of the three-phase power access slot 511, three-phase electricity can be connected to the distribution box 51 and supplied to the pneumatic motor 33.

[0055] The sorting member 4 may be a sorting plate, and a sorting opening is correspondingly provided on one side of the two sorting plates that are close to each other, and the two corresponding sorting openings are in opposite semicircular shapes, and the two corresponding sorting openings form the sorting gap 41. When the potatoes pass through the sorting gap 41, potatoes smaller than the sorting gap 41 can fall from the sorting gap 41, thereby realizing the sorting of potatoes.

[0056] The heights of at least three of the sorting members 4 are gradually reduced along the first direction, so that after the potatoes enter the sorting trough 21, the potatoes can be ensured to move along the first direction.

[0057] See also Figure 1 and Figure 5 At least three of the sorting members 4 include at least three sorting rollers, the sorting rollers are perpendicular to the first direction, and the sorting rollers are rotatably installed in the sorting box 2, and the sorting box 2 is provided with a driving assembly 6 for driving at least three of the sorting rollers to rotate in the same direction.

[0058] When the length of the potato along the first direction is less than the width of the sorting gap 41 between two adjacent sorting rollers, the potato can fall from between the two sorting rollers. The driving assembly 6 can drive at least three sorting rollers to rotate synchronously. When at least three sorting rollers rotate synchronously, the dynamic potato can be rotated to adjust the posture of the potato. When the potato rotates to a certain position and the length of the potato in the first direction is less than the width of the sorting gap 41 between two adjacent sorting rollers, the potato falls from the sorting gap 41, and as a whole, the smaller potato falls from the smaller sorting gap 41. When the potato is large, the adjacent sorting rollers rotate to move the potato and enter the next sorting gap 41.

[0059] Specifically, the sorting elements 4 can be set to four, five or more.

[0060] The driving assembly 6 may include a first gear, a second gear, a synchronization rod and a driving motor 61. The driving motor 61 is arranged on the sorting box 2. A plurality of first gears are arranged corresponding to the sorting rollers one by one. The first gears are coaxially fixedly connected to the corresponding sorting rollers. The synchronization rod is fixedly connected to the output shaft of the driving motor 61. A plurality of second gears are arranged corresponding to the first gears one by one, and a plurality of second gears are coaxially fixedly connected to the synchronization rod. The corresponding first gear cooperates with the first gear. When the driving motor 61 is started, the synchronization rod rotates and drives the second gear to rotate. The plurality of first gears rotate synchronously, thereby realizing the synchronous rotation of the plurality of sorting rollers.

[0061] In the embodiment of the present application, the driving component 6 includes:

[0062] A driving motor 61 is provided on the sorting box 2;

[0063] a drive belt 62; and,

[0064] The active roller 63 is coaxial with the sorting roller and is coaxially arranged on the output shaft of the driving motor 61 . The active roller 63 is connected to at least three of the sorting elements 4 via the transmission belt 62 .

[0065] When the driving motor 61 is started, the active roller 63 and the transmission belt 62 can drive the multiple sorting rollers to rotate synchronously. Furthermore, two groups of driving components 6 are provided on opposite sides of the sorting rollers, and the two groups of driving components 6 cooperate with each other to ensure the stable rotation of the sorting rollers.

[0066] Specifically, the sorting roller is coaxially fixedly connected with a driven roller 42 , and the driven roller 42 is connected to the driving roller 63 via the transmission belt 62 .

[0067] The potato sorting machine further includes a sensing device 7, which is disposed at one end of the filling box 1 close to the sorting box 2, and is used to sense potatoes. Specifically, the sensing device 7 is an infrared sensing device 7, and the potato sorting machine further includes a control device, which is electrically connected to the sensing device 7, and the control device is electrically connected to the drive motor 61. After the push rod 321 pushes the potatoes into the sorting slot 21, the sensing device 7 can transmit a signal to the control device, and the control device can start the drive motor 61 to drive the sorting roller to sort the potatoes.

[0068] See also Figure 1 and Figure 6The potato sorting machine further comprises a plurality of receiving buckets 8, which are fixedly connected to the sorting box 2, are arranged in sequence along the first direction, and the top opening of the receiving bucket 8 corresponds to the discharge port. With the aid of the receiving bucket 8, the sorted potatoes can be received to ensure that the sorted potatoes are temporarily stored in batches. In the present application, four receiving buckets 8 are provided.

[0069] The receiving bucket 8 is provided with a weighing module 82, which is used to weigh the potatoes in the receiving bucket 8. The weighing module 82 can weigh the potatoes in the receiving bucket 8. When the potatoes in the receiving bucket 8 reach a preset weight, the potatoes in the receiving bucket 8 can be bagged and the receiving bucket 8 can be emptied, so that the receiving bucket 8 can receive potatoes for the next sorting.

[0070] The bottom of the receiving bucket 8 is provided with a packing opening 81, and a baffle 9 is provided at the bottom of the receiving bucket 8 corresponding to the packing opening 81. The potato sorting machine further comprises a control member, and the control member is used to control the opening of the baffle 9. When the potatoes in the receiving bucket 8 reach a preset weight, the control member is controlled to make the push plate 31 move away from the packing opening 81, so that the packing opening 81 is opened, and the potatoes can fall from the packing opening 81, and the woven bag can be directly opened at the lower side of the packing opening 81, and the potatoes can fall from the receiving bucket 8 into the woven bag.

[0071] The baffle plate 9 is hinged at the bottom of the receiving bucket 8, and a first elastic member is connected between the receiving bucket 8 and the baffle plate 9, and the first elastic member is used to drive the baffle plate 9 to close the discharge port. After the potatoes in the receiving bucket 8 fall from the packing port 81, the first elastic member can drive the baffle plate 9 to rotate and approach the packing port 81 to close the packing port 81.

[0072] See also Figure 1 and Figure 6 The first elastic member can be any elastic long rod. In the embodiment of the present application, the first elastic member is a spring, one end of the spring is connected to the side of the baffle 9 away from the hinge axis of the baffle 9, and the other end is connected to the receiving bucket 8. The control member is any locking member that realizes the rotation of the baffle 9.

[0073] When the potatoes in the receiving bucket 8 reach a preset weight, the control component controls the baffle 9 to open, that is, the control component does not lock the rotation of the baffle 9. Under the pressure of the potatoes, the baffle 9 rotates and opens. When the baffle 9 rotates to the maximum angle, the control component controls the rotation lock of the baffle 9, which facilitates the potatoes in the receiving bucket 8 to fully fall from the packaging port 81.

[0074] When all the potatoes in the receiving bucket 8 fall from the packing port 81, the control member is controlled to allow the baffle 9 to rotate naturally. The baffle 9 can rotate and approach the packing port 81 driven by the first elastic member to close the packing port 81. When the packing port 81 is closed, the control member is controlled to lock the rotation of the baffle 9. The baffle 9 can support the potatoes in the receiving bucket 8 and reduce the leakage of the potatoes in the receiving bucket 8.

[0075] In the embodiment of the present application, two baffles 9 are provided on one receiving bucket 8 .

[0076] The potato sorting machine further includes a fixed frame 10, on which the filling box 1 and the sorting box 2 are both mounted, and the fixed frame 10 further includes a plurality of columns 101 and a plurality of beams 102, wherein the beams 102 connect adjacent columns 101, thereby ensuring the stability of the fixed frame 10 and providing a space for placing woven bags between the bag loading port 81 and the installation ground. Specifically, six columns 101 are provided, and seven beams 102 are provided.

[0077] In the embodiment of the present invention, the driving assembly 6 can drive at least three of the sorting rollers to rotate synchronously. When at least three of the sorting rollers rotate synchronously, the dynamic potatoes can be rotated to adjust the posture of the potatoes. When the potatoes rotate to a certain position and the length of the potatoes in the first direction is less than the width of the sorting gap 41 between two adjacent sorting rollers, the potatoes fall from the sorting gap 41, and the smaller potatoes fall from the smaller sorting gap 41 as a whole. When the potatoes are large, the adjacent sorting rollers rotate to move the potatoes and enter the next sorting gap 41. The problem of large differences between potatoes sorted to the same specification is improved as a whole.

[0078] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention.
