[0055] The structure of the reversing finger 1-22 is as Figure 11 and 12 shown. The structure of the reversing finger 2-25 is the same as that of the reversing finger 1-22.

[0056] Refer to Figure 5 and 7 , when the reversing finger 1-22 is in the initial state, in this initial state, the reversing finger 1-22 is not connected to the rear end of the main direction track 11. At this time, when the electromagnet 1-24 operates, the rotating shaft of the electromagnet 1-24 rotates by a certain angle, and the rotating shaft of the electromagnet 1-24 drives the reversing finger 1-22 to rotate by a certain angle in the direction of the rear end of the main direction track 11. The free end of the reversing finger 1-22 is close to the rear end of the main direction track 11. Refer to Figure 10 , to achieve the connection between the reversing finger 1-22 and the rear end of the main direction track 11.

[0057] The working mode of the reversing finger 2-25 is the same as that of the reversing finger 1-22. The rotating shaft of the electromagnet 2-27 rotates by a certain angle, driving the reversing finger 2-25 to rotate by a certain angle in the direction of the rear end of the segmented main direction track 1-12. The free end of the reversing finger 2-25 is close to the rear end of the segmented main direction track 1-12. Refer to Figure 8 , to achieve the connection between the reversing finger 2-25 and the rear end of the segmented main direction track 1-12.

[0058] Refer to Figure 4 , 5 , 7 and 19, the main direction track 11 is provided with a vertical portion 11-1. Similarly, the segmented main direction track 1-12 is also provided with a vertical portion, and the segmented main direction track 2-13 is also provided with a vertical portion. Refer to Figure 4 , 5 and 20, the shunt track 1-14 is provided with a vertical portion 14-1, and the grading track 1-16 is provided with a vertical portion 16-1. Refer to Figure 4 ,8 And 21, the diverging track two 15 is provided with a vertical part 15-1, and the grading track two 17 is provided with a vertical part 17-1.

[0059] As Figures 13-16 As shown, the tray 28 includes a base 28-1, a guide shaft 28-2, and a profiling lifting plate 28-3. The guide shaft 28-2 is fixedly connected to the bottom of the base 28-1. Seven profiling lifting plates 28-3 are respectively connected to the top of the base 28-1, and the seven profiling lifting plates 28-3 are arranged in a line. The base 28-1 is provided with a first chute 28-1-1 and a second chute 28-1-2. The first chute 28-1-1 and the second chute 28-1-2 are arranged side by side and are arranged along the length direction of the base 28-1. The profiling lifting plate 28-3 is provided with a groove 28-3-1. When the cucumber is lifted by the seven profiling lifting plates, different parts of the cucumber are located in the grooves 28-3-1 of each profiling lifting plate 28-3; preferably, the lengths of the grooves on the 5th, 6th, and 7th profiling lifting plates are equal, L5 = L6 = L7, the lengths of the grooves on the 1st, 2nd, 3rd, and 4th profiling lifting plates gradually decrease, L1 > L2 > L3 > L4, and the length of the groove on the 5th profiling lifting plate is less than the length of the groove on the 4th profiling lifting plate (L5 < L4); the centers of the 7 points of L1, L2, L3, L4, L5, L6, and L7 can be connected into an arc, imitating the arc of the cucumber, that is, the 7 grooves form a limiting space adapted to the shape of the cucumber. Refer to Figure 24 , the grooves on the 5th, 6th, and 7th profiling lifting plates are used to limit the tail of the cucumber (the tail of the cucumber refers to the end without thorns), and the grooves on the 1st, 2nd, 3rd, and 4th profiling lifting plates are used to limit the parts other than the tail of the cucumber. The limiting space formed by the combination of the grooves on the multiple profiling lifting plates can stably and reliably lift the cucumber and prevent the cucumber from rolling or falling off the tray due to working conditions such as sudden stop and speed change.

[0060] As Figure 18 As shown, when the tray 28 cooperates with two stainless steel tubes 4-3 on the stainless steel tube conveyor belt 4, the two stainless steel tubes 4-3 respectively pass through the first chute 28-1-1 and the second chute 28-1-2, so that the base 28-1 can slide along the two stainless steel tubes 4-3. The sliding of the base 28-1 along the two stainless steel tubes 4-3 is the sliding in the transverse direction of the stainless steel tube conveyor belt 4. Refer to Figure 1 And 2, a plurality of trays 28 are cooperatively connected with the stainless steel tubes on the stainless steel tube conveyor belt 4. When the stainless steel tube conveyor belt 4 operates, the stainless steel tubes move in the longitudinal direction, thereby driving the trays 28 to move in the longitudinal direction. The trays can be used for sorting operations without height difference to avoid damaging fragile fruits and vegetables or those with high appearance requirements.

[0061] To reduce the weight of the tray 28, the first chute 28-1-1 and the second chute 28-1-2 of the base 28-1 are formed by arranging eight rib plates in a row. Refer to Figure 14 and 17 and 16. The base 28-1 is provided with eight rib plates 28-1-3. Two symmetrically arranged U-shaped grooves are provided on both sides of each rib plate 28-1-3. In this way, the eight U-shaped grooves on one side of the eight rib plates form the first chute 28-1-1, and the eight U-shaped grooves on the other side of the eight rib plates form the second chute 28-1-2. The design of multiple rib plates not only reduces the weight but also ensures the fit between the chute and the stainless steel tube. The light weight of the tray is beneficial to reducing the moment of inertia and facilitating reliable sliding.

[0062] As Figure 19 and 22 shown, during the input stage of the working process of the entire turnout type fruit and vegetable sorting device, the guide shaft 28-2 of the tray 28 moves along the vertical part 11-1 of the main track 11. Figure 22 In, the direction indicated by the upper arrow is the moving direction of the upper tray, and the direction indicated by the lower arrow is the moving direction of the lower tray.

[0063] The disclosed turnout type sorting device has a turnout type sorting method, and the sorting speed is fast and the efficiency is high; the entire sorting process is completed without height difference, which will not damage the fruits and vegetables and can provide good protection for the fruits and vegetables. It is not limited to fragile or fruits and vegetables with high appearance requirements, but can also be applied to other fruits and vegetables. It is not limited to sorting fruits and vegetables, but can also sort any other items that can be sorted.

[0064] The working process of the above-mentioned turnout type fruit and vegetable sorting device is introduced below:

[0065] Refer to Figure 24 , one cucumber 29 is placed on each of the multiple profiling lifting plates 28-3 of each tray 28. The drive mechanism is started, and the stainless steel tube conveyor belt 4 moves cyclically. The multiple trays located on the upper layer move in the direction indicated by the arrow in the figure. During the input stage of the working process, the guide shaft 28-2 of the tray moves along the vertical part 11-1 of the main track 11 (as Figure 22 shown).

[0066] The cucumbers on the tray in the input stage are graded as good or bad through machine vision technology. The controller sends control instructions to the first electromagnet 24 and the second electromagnet 27 according to the grade data, causing the first electromagnet 24 and the second electromagnet 27 to act. The first reversing finger 22 is not connected to the rear end of the main track 11 in the initial state (as shown in Figure 5 , 7 and 19). The rotating shaft of the first electromagnet 24 rotates a certain angle, making the free end of the first reversing finger 22 close to the rear end of the main track 11 (as shown in Figure 10 ). Then, the guiding shaft of the tray will move along the first reversing finger 22 to the first shunt track 14, and the guiding shaft will abut against the vertical part 14-1 of the first shunt track 14 and slide, and finally the tray will move obliquely forward along the first shunt track 14 (towards the output end of the switch-type fruit and vegetable sorting device). Figure 24 The trays where the cucumbers 30, 31, 32, 33, 34, and 35 shown in Figure 24 are located all move along the first shunt track 14. The guiding shafts of these trays move from the rear end of the first shunt track 14 to the first grading track 16 and abut against the vertical part 16-1 and slide (move along the longitudinal direction). When the rotating shaft of the first electromagnet 24 reverses a certain angle to make the first reversing finger 22 return to the initial state, at this time, no tray will be shunted to the first shunt track 14, and the tray on the main track 11 will directly move from the rear end of the main track 11 to the front end of the segmented main track 12 and continue to move forward along the segmented main track 12.

[0067] For the trays on the segmented main track 12, the second reversing finger 25 is not connected to the rear end of the segmented main track 12 in the initial state. The rotating shaft of the second electromagnet 27 rotates a certain angle, making the free end of the second reversing finger 25 close to the rear end of the segmented main track 12 (as shown in Figure 8 ). Then, the guiding shaft of the tray will move along the second reversing finger 25 to the second shunt track 15, and the guiding shaft will abut against the vertical part 15-1 of the second shunt track 15 and slide, and finally the tray will move obliquely forward along the second shunt track 15 (towards the output end of the switch-type fruit and vegetable sorting device). Figure 24The cucumbers 38, 39, 40, and 41 shown are all moving along the shunt track two 15. The guide shafts of these trays move from the rear end of the shunt track two 15 to the grading track two 17 and slide (move along the longitudinal direction) against the vertical part 17-1. When the rotating shaft of the electromagnet two 27 reverses by a certain angle to make the reversing finger two 25 return to the initial state, no trays will be shunted onto the shunt track two 15 at this time. The trays on the segmented main track one 12 will move directly from its rear end to the front end of the segmented main track two 13 and continue to move forward along the segmented main track two 13. Figure 24 The trays 42, 43, 44, 45, 46, 47, and 48 shown are all moving along the segmented main track two 13.

[0068] It can be seen that at the output end of the switch-type fruit and vegetable sorting device, three positions in the horizontal direction output three grades of cucumbers respectively. The cucumbers placed on the trays 42, 43, 44, 45, 46, 47, and 48 belong to grade one, the cucumbers 38, 39, 40, and 41 belong to grade two, and the cucumbers 30, 31, 32, 33, 34, and 35 belong to grade three.

[0069] After the cucumbers at the three positions at the output end of the switch-type fruit and vegetable sorting device are taken away or dropped, the corresponding trays move to the lower layer. The guide shafts of the trays 42, 43, 44, 45, 46, 47, and 48 move along the confluence track 19, and after moving to the rear end of the confluence track 19, they turn upwards and then move to the front end of the main track 11 to achieve circulation. The guide shafts of the trays where the cucumbers 30, 31, 32, 33, 34, and 35 are located disengage from the rear end of the grading track one 16, then move to the front end of the return track one 20 and slide against the vertical part of the return track one 20 until they reach the confluence track 19, and then turn upwards from the rear end of the confluence track 19 and move to the front end of the main track 11.

[0070] The guide shafts of the trays where the cucumbers 38, 39, 40, and 41 are located disengage from the rear end of the grading track two 17, then move to the front end of the return track two 21 and slide against the vertical part of the return track two 21 until they reach the confluence track 19, and then turn upwards from the rear end of the confluence track 19 and move to the front end of the main track 11.

[0071] It can be seen that due to the fast response and action of the electromagnet, the corresponding commutation finger moves relatively fast, and the speed of diverting the tray is relatively fast, which can meet the requirement of the fast movement of the tray and the high efficiency of grading at the output end of the turnout type fruit and vegetable sorting device. The entire sorting process is completed without a height difference, and the cucumbers will not roll over, causing no damage to the cucumbers, and providing good protection for the cucumbers.

[0072] There is no height difference in the sorting process, nor is there a large impact force.

[0073] It should be noted that for the tray 28, the groove shapes and sizes on the multiple profiling lifting plates 28-3 can be changed to adapt to the lifting of other rod-shaped fruits and vegetables besides cucumbers.

[0074] It should be noted that for the tray 28, the multiple profiling lifting plates 28-3 can also be replaced by lifting components with other structures to achieve the lifting function of rod-shaped fruits and vegetables such as cucumbers, or to achieve the lifting of fruits and vegetables other than rod-shaped fruits and vegetables, or to achieve the lifting of items other than fruits and vegetables (the item can be any item that can be lifted).

[0075] It should be noted that some structures in the above-mentioned turnout type diversion mechanism can be changed. Refer to Figure 25 , remove the sectional main track one 12 and the sectional main track two 13, and extend the main track 11 in Figure 5 to form the main track 49, that is, only one main track 49 in the longitudinal direction is needed. Then, replace the electromagnet connecting seat one 23 with the electromagnet connecting seat one 50 (in this way, there is no need to reserve an installation space for the electromagnet connecting seat one as shown in Figure 5 ), and replace the electromagnet connecting seat two 26 with the electromagnet connecting seat two 51 (in this way, there is no need to reserve an installation space for the electromagnet connecting seat two as shown in Figure 5 ). The front end of the diversion track one 14 is close to the main track 49, and the commutation finger one 22 is located between the front end of the diversion track one 14 and the main track 49; the front end of the diversion track two 15 is close to the main track 49, and the commutation finger two 25 is located between the front end of the diversion track two 15 and the main track 49. Therefore, when the commutation finger one 22 moves, the free end of the commutation finger one 22 is close to the main track 49; when the commutation finger two 25 moves, the free end of the commutation finger two 25 is close to the main track 49.

[0076] The confluence track 19 is located directly below the main track 49.

[0077] The above is only for the preferred embodiments of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
