The collecting part can accurately collect the potatoes conveyed from the feeding pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0045] In this embodiment, please refer to Figures 1 to 7 The utility model provides an automatic potato sorting and collecting device, comprising: a supporting mechanism 1, a sorting mechanism 2 and a feeding and collecting mechanism 3. The supporting mechanism 1 comprises a box body 11, a supporting shaft 12 fixedly connected to the box body 11, a top plate 13 fixedly connected to the top end of the support shaft 12, a first spiral plate 14, a second spiral plate 15 and a third spiral plate 16, the two ends of the second spiral plate 15 are respectively fixedly connected to the first spiral plate 14 and the third spiral plate 16, and the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 are all fixedly connected to the top plate 13 through a plurality of support arms 17; the bottom of the box body 11 is provided with rollers around. After the rollers are installed around the bottom of the box body 11, the position of the entire device is easy to adjust, and the position can be flexibly changed according to actual usage scenarios, different work locations, etc., which improves practicality and convenience and can better adapt to different working environments and needs.

[0046] The sorting mechanism 2 includes a plurality of first sorting rollers 21, a plurality of second sorting rollers 22, a plurality of third sorting rollers 23, two first spiral rods 24, two second spiral rods 25 and two third spiral rods 26, one end of the plurality of first sorting rollers 21 is vertically fixed to the two ends of the first spiral plate 14 in the width direction and is arranged at intervals of a first pitch along the spiral direction, one end of the plurality of second sorting rollers 22 is vertically fixed to the two ends of the second spiral plate 15 in the width direction and is arranged at intervals of a second pitch along the spiral direction, one end of the plurality of third sorting rollers 23 is vertically fixed to the two ends of the third spiral plate 16 in the width direction and is arranged at intervals of a third pitch along the spiral direction, and the two first spiral rods 24 are respectively connected to the other ends of the plurality of first sorting rollers 21 located at the two ends of the first spiral plate 14 in the width direction. The two second spiral rods 25 are fixedly connected to the other ends of the second sorting rollers 22 located at both ends of the second spiral plate 15 in the width direction, and the two third spiral rods 26 are fixedly connected to the other ends of the third sorting rollers 23 located at both ends of the third spiral plate 16 in the width direction. A sealing plate 27 is provided at one end of the lower side of the third spiral plate 16. The first spacing is smaller than the second spacing, and the second spacing is smaller than the third spacing. The box body 11 has a feeding port 28 that is smoothly and fixedly connected to the first spiral plate 14. The feeding and collecting mechanism 3 has three groups, and the three groups of feeding and collecting mechanisms 3 are used to respectively transport and collect potatoes of different sizes sorted from the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16.

[0047] Potatoes are dropped into the box 11 from the feed port 28. Leveraging the weight of the potatoes themselves and the guidance of the spiral structure, the potatoes are able to roll smoothly from a high position to a low position. After entering the first spiral plate 14, the potatoes undergo preliminary screening. Smaller potatoes fall between a plurality of first sorting rollers 21 arranged at a first pitch on the first spiral plate 14 and enter the feeding and collecting mechanism 3 for conveyance. Larger potatoes then fall between a plurality of second sorting rollers 22 arranged at a second pitch on the second spiral plate 15 and a plurality of third sorting rollers arranged at a third pitch on the third spiral plate 16, respectively, and enter the feeding and collecting mechanism 3 for conveyance. This allows potatoes of different sizes to be accurately screened out, thereby achieving the effect of sorting potatoes of different sizes. By making the first pitch smaller than the second pitch, and the second pitch smaller than the third pitch, the potatoes gradually separate during the sorting process, improving sorting accuracy and efficiency. The three groups of feeding and collecting mechanisms 3 correspond to the potatoes of different sizes sorted on the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 respectively, thereby realizing the classified transportation and collection of the sorted potatoes, facilitating the subsequent targeted processing, packaging or other subsequent operations of potatoes of different specifications, thereby solving the problem of easy sorting errors during manual operation, which leads to the risk of rework.

[0048] In this embodiment, please refer to Figure 2 The first spiral plate 14 has a first potato leakage hole 141 along its own width direction, and the first potato leakage hole 141 has a plurality of first potato leakage holes 141, and the plurality of first potato leakage holes 141 are arranged at a first pitch along the spiral direction of the first spiral plate 14; and / or, the second spiral plate 15 has a second potato leakage hole 151 along its own width direction, and the second potato leakage hole 151 has a plurality of second potato leakage holes 151, and the plurality of second potato leakage holes 151 are arranged at a second pitch along the spiral direction of the second spiral plate 15; and / or, the third spiral plate 16 has a third potato leakage hole 161 along its own width direction, and the third potato leakage hole 161 has a plurality of third potato leakage holes 161, and the plurality of third potato leakage holes 161 are arranged at a third pitch along the spiral direction of the third spiral plate 16.

[0049] The first, second, and third potato holes 141, 151, and 161, arranged at first, second, and third spacings on the first, second, and third spiral plates 14, 15, and 16, respectively, allow potatoes of different sizes to be quickly and efficiently sorted, improving sorting efficiency and enhancing uniform flow and stability during transport. The first, second, and third potato holes 141, 151, and 161 can all be rectangular. Rectangular first, second, and third potato holes 141, 151, and 161 allow for more accurate potato size screening. The rectangular sides better match the shape of the potatoes, effectively preventing potatoes from being misscreened due to their rolling posture. The rectangular sides guide the rolling direction of the potatoes, altering their path as they roll.

[0050] In this embodiment, please refer to Figures 2 to 4 The support mechanism 1 further includes a plurality of reinforcing arms 18, which respectively securely connect the first spiral plate 14, the second spiral plate 15, and the third spiral plate 16 to the sidewalls of the support shaft 12. The plurality of reinforcing arms 18 respectively securely connect the first spiral plate 14, the second spiral plate 15, and the third spiral plate 16 to the sidewalls of the support shaft 12, significantly enhancing the connection stability between the spiral plates and the support shaft 12 and providing support and reinforcement.

[0051] In this embodiment, please refer to Figure 1 、 Figure 3 and Figure 4 The feeding and collecting mechanism 3 includes a first feeding component 31, a second feeding component 32, a third feeding component 33 and three collecting modules 34. The first feeding component 31, the second feeding component 32 and the third feeding component 33 have the same structure;

[0052] The first feeding assembly 31 includes a spiral span plate 311, two spiral arc plates 312, a spiral bottom plate 313, two side plates 314 and a feeding pipe 315 that are arranged across the two first spiral rods 24. The bottom width of the spiral span plate 311 is greater than the bottom width of the first spiral plate 14. The two ends of the two spiral arc plates 312 are fixedly connected to the two ends of the spiral span plate 311 in the width direction and the two ends of the spiral bottom plate 313 in the width direction, and the two ends of the two side plates 314 are fixedly connected to the two ends of the spiral bottom plate 313 and the bottom of the first spiral plate 14. The spiral span plate 311, the spiral bottom plate 313, the two spiral arc plates 312 and the two side plates 314 enclose a feeding space 316. The feeding pipe 315 is located on the lower end side of the spiral bottom plate 313 and is connected to the feeding space 316.

[0053] The screw cross plate 311 of the second feeding assembly 32 is arranged above the two second screw rods 25, and the two side plates 314 are respectively fixedly connected with the two ends of the screw bottom plate 313 and the bottom of the second spiral plate 15.

[0054] The screw cross plate 311 of the third feeding assembly 33 is arranged above the two third screw rods 26, and the two side plates 314 are respectively fixedly connected with the two ends of the screw bottom plate 313 and the bottom of the third spiral plate 16.

[0055] The three collection modules 34 are used to collect the potatoes transported out of the feeding pipes 315 of the first feeding assembly 31, the second feeding assembly 32 and the third feeding assembly 33 respectively.

[0056] Through the one-to-one correspondence between the first feeding assembly 31, the second feeding assembly 32 and the third feeding assembly 33 and the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 respectively, the sorted potatoes can be transported respectively, so that the one-to-one corresponding collection modules 34 can be smoothly transported. The feeding space 316 is formed by the cooperation of the screw cross plate 311, the screw bottom plate 313, the two screw arc plates 312 and the two side plates 314, and the feeding pipe 315 is located on one side of the low end of the screw bottom plate 313 and communicates with the feeding space 316. When the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 respectively sort out the potatoes, the feeding space 316 can provide a stable transport environment for the potatoes, and the accuracy and stability of the transport are improved. The feeding pipe 315 can be in an arc structure, and when the potatoes enter the arc-shaped feeding pipe 315 from the feeding space 316, the arc-shaped pipe wall can provide a soft buffer for the potatoes, and the arc-shaped feeding pipe 315 can better guide the flow of the potatoes.

[0057] In the embodiment, please refer to Figure 5 and Figure 6 Each of the collection modules 34 includes a first buffer part 341, a second buffer part 342 and a collection part 343. The second buffer part 342 includes a plurality of annular air bags 3421, and the plurality of annular air bags 3421 are arranged along the transport direction of the feeding pipe 315. The first buffer part 341 buffers and dissipates the energy of the sorted potatoes for the first time, and the collection part 343 is used to collect the potatoes transported out of the feeding pipe 315.

[0058] When potatoes are sorted out on the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16, the potatoes are buffered and dissipated by the first buffer portion 341, thereby initially reducing the impact force on the potatoes. The potatoes are then able to roll smoothly from a high place to a low place by utilizing their own gravity and the guiding effect of the spiral structure. The potatoes then fall into the feeding tube 315 through the first buffer portion 341. Multiple annular airbags 3421 are arranged along the conveying direction of the feeding tube 315, so that the multiple annular airbags 3421 cushion the potatoes, thereby effectively preventing damage caused by collisions during the potato conveying process. The collecting portion 343 can accurately collect the potatoes conveyed out of the feeding tube 315.

[0059] In this embodiment, please refer to Figure 5 The diameters of the multiple annular airbags 3421 gradually decrease along the feeding direction of the feeding tube 315. As the diameters of the multiple annular airbags 3421 gradually decrease along the feeding direction of the feeding tube 315, the annular airbags 3421 provide a stronger cushioning effect on the potatoes, thereby more effectively absorbing the kinetic energy of the potatoes and providing a better cushioning effect.

[0060] In this embodiment, please refer to Figures 5 to 7 The first buffer portion 341 includes a spiral buffer plate 3411 and a first elastic member 3412. The widthwise ends of the upper end of the spiral buffer plate 3411 are rotatably connected to the sidewalls of the two spiral arc-shaped plates 312. The first elastic member 3412 is used to reset the spiral buffer plate 3411 upward. The first elastic member 3412 comprises a spring, the ends of which are fixedly connected to the spiral buffer plate 3411 and the spiral base plate 313, respectively, providing a stable and continuous reset force for the spiral buffer plate 3411.

[0061] During operation, when potatoes are sorted out by the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16, the potatoes fall onto the spiral buffer plate 3411, and the elastic member is compressed downward, thereby initially reducing the impact force on the potatoes. The potatoes can then roll smoothly from a high place to a low place by utilizing the gravity of the potatoes themselves and the guiding effect of the spiral structure. The potatoes then fall into the feed pipe 315 through the spiral buffer plate 3411. After completing one conveying, the elastic member resets the spiral conveying plate upward to prepare for the next buffering.

[0062] In this embodiment, please refer to Figure 7 The first elastic members 3412 have multiple first elastic members 3412, and the multiple first elastic members 3412 are arranged at intervals along the spiral direction of the spiral buffer plate 3411, which can make the reset force evenly distributed at various positions of the spiral buffer plate 3411, thereby improving the uniformity of the buffering effect and enhancing the connection stability between the spiral buffer plate 3411 and the spiral bottom plate 313.

[0063] In this embodiment, please refer to Figure 7 The first buffer portion 341 further includes a spiral airbag cushion 3413, which is fixed to the top of the spiral buffer plate 3411. When a potato rolls down and hits the spiral buffer plate 3411, the spiral airbag cushion 3413 first contacts the potato, utilizing the compressibility of the gas within the airbag to absorb some of the impact force, thereby further effectively preventing the potato from being damaged or broken.

[0064] In this embodiment, please refer to Figure 5 and Figure 6 The collecting portion 343 includes a base 3431 fixedly connected to the side wall of the box body 11, an L-shaped plate 3432, a collecting frame 3433, two side arms 3434, a limiting plate 3435 and a second elastic member 3436. The L-shaped plate 3432 is rotatably connected to the base 3431 at a vertical position, and the two ends of the two side arms 3434 are fixedly connected to the vertical part and the horizontal part at the two ends of the L-shaped plate 3432 in the width direction respectively. The limiting plate 3435 is perpendicular to and fixedly connected to the end of the L-shaped plate 3432. The L-shaped plate 3432, the limiting plate 3435 and the two side arms 3434 form a accommodating space. The collecting frame 3433 is placed in the space. The horizontal part of the L-shaped plate 3432 has a weight sensor, which can monitor the weight of potatoes in the collecting frame 3433 in real time, thereby improving the efficiency of the entire collection work. The second elastic member 3436 is used to reset the L-shaped plate 3432 away from the base 3431. The second elastic member 3436 includes a spring.

[0065] An accommodating space is formed by the L-shaped plate, the limiting plate 3435 and the two side arms 3434 to place the collection frame 3433, so that when the collection frame 3433 is full of potatoes, it is easy to take out and place the next collection frame 3433. When the second elastic member is initially in an uncompressed state, the collection frame 3433 is in an inclined state, and the potatoes delivered by the feeding tube 315 can roll along the side wall of the collection frame 3433 into the collection frame 3433, further preventing the potatoes from being damaged due to collision. The second elastic member 3436 is a spring that can also play a buffering role when the potatoes fall in.

[0066] Working principle: When in use, potatoes are put into the box body 11 from the feed port 28. The potatoes can roll smoothly from high to low by utilizing the gravity of the potatoes themselves and the guiding effect of the spiral structure. After the potatoes first enter the first spiral plate 14, they are first preliminarily screened. The smaller potatoes fall through the first sorting rollers 21 arranged at a first pitch on the first spiral plate 14 and the first potato leakage hole 141 and enter the feeding and collecting mechanism 3 for transportation. The larger potatoes fall through the second sorting rollers 22 arranged at a second pitch on the second spiral plate 15 and the second potato leakage hole 151, and the third sorting rollers arranged at a third pitch on the third spiral plate 16 and the third potato leakage hole 161 and enter the feeding and collecting mechanism 3 for transportation respectively, so that potatoes of different sizes can be accurately screened out. The potatoes are screened out by the spiral cross plate 311, the spiral bottom plate 313, and the two spiral arc plates 312. The cooperation with the two side plates 314 forms a feeding space 316, and the feeding pipe 315 is located on the lower end side of the spiral bottom plate 313 and is connected to the feeding space 316. When potatoes are sorted out from the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16, the potatoes roll down and hit the spiral buffer plate 3411. The spiral airbag cushion 3413 first contacts the potatoes and uses the compressibility of the gas in the airbag to absorb part of the impact force. The potatoes fall onto the spiral buffer plate 3411, and the elastic member is compressed downward, which preliminarily reduces the impact force on the potatoes. The potatoes are able to roll smoothly from a high place to a low place by using the gravity of the potatoes themselves and the guiding effect of the spiral structure. Then the potatoes fall into the feeding pipe 315 through the spiral buffer plate 3411. A plurality of annular airbags 3421 are arranged along the conveying direction of the feeding pipe 315, so that the plurality of annular airbags 3421 cushion the potatoes. The collection frame 3433 is placed on the L The mold plate, the limit plate 3435 and the two side arms 3434 form a accommodating space. When the second elastic member is initially in an uncompressed state, the collection frame 3433 is in an inclined state. The potatoes delivered by the feeding tube 315 can roll along the side wall of the collection frame 3433 into the collection frame 3433, further preventing the potatoes from being damaged due to collision. The second elastic member 3436 is a spring and can also play a buffering role when the potatoes fall in. The weight sensor monitors the weight of the potatoes in the collection frame 3433 in real time. As the number of potatoes in the collection frame 3433 increases, the second elastic member 3436 is compressed, and the inclination angle becomes smaller. After reaching the set weight, the next collection frame 3433 is replaced.

[0067] In summary, the utility model discloses a potato is put into the box 11 from the feed inlet 28, utilizes the gravity of potato and the guiding action of spiral structure, and potato can roll smoothly from high to low, and the first preliminary screening is carried out to the potato after entering the first spiral plate 14 first, and the smaller potato falls down and is transported in the feeding collection mechanism 3 through the first spacing interval arrangement of multiple first sorting rollers 21 on the first spiral plate 14, and the larger potato falls down and is transported in the feeding collection mechanism 3 through the second spacing interval arrangement of multiple second sorting rollers 22 on the second spiral plate 15 and the third spacing interval arrangement of multiple third sorting rollers on the third spiral plate 16 respectively, so that the potato of different sizes can be accurately screened out, thereby achieving the effect that the potato is sorted out in different sizes. Through the first spacing smaller than the second spacing, the second spacing smaller than the third spacing, the potato is gradually separated during the sorting process, and the accuracy and efficiency of sorting are improved. Through three groups of feeding collection mechanisms 3 corresponding to the different sizes of the potato sorted on the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 respectively, the sorted potato is classified, transported and collected, which is convenient for subsequent targeted processing, packaging or other subsequent operations of the different specifications of the potato, thereby solving the problem of sorting error in the manual operation process, which leads to the risk of rework. The first potato hole 141, the second potato hole 151 and the third potato hole 161 arranged at the first spacing, the second spacing and the third spacing on the first spiral plate 14, the second spiral plate 15 and the third spiral plate 16 respectively can quickly and efficiently screen out the potato of different sizes, improve the sorting efficiency, and also improve the uniform flow and stability in the conveying process. The first potato hole 141, the second potato hole 151 and the third potato hole 161 can all be rectangular structures. The first potato hole 141, the second potato hole 151 and the third potato hole 161 of the rectangular structure are more accurate for the size screening of the potato, and the side length of the rectangle can better match the shape characteristics of the potato, thereby effectively preventing the potato from being mis-screened due to the rolling posture. The side of the rectangular structure can guide the rolling direction of the potato, and when the potato rolls, the side of the rectangle can change the rolling path of the potato. Through the first buffer part 341, the impact force on the potato is initially reduced, and the gravity of the potato itself and the guiding action of the spiral structure enable the potato to roll smoothly from high to low, and then the potato falls into the feeding pipe 315 through the first buffer part 341, a plurality of annular air bags 3421 are arranged along the conveying direction of the feeding pipe 315, so that the plurality of annular air bags 3421 buffer the potato, thereby effectively preventing the potato from being damaged due to collision during the conveying process, and the collecting part 343 can accurately collect the potato conveyed in the feeding pipe 315. Therefore, the utility model effectively overcomes the shortcomings in the prior art and has high industrial utilization value.
