Description

Technical Field

[0001] This invention belongs to the field of seed cutting machine technology, and in particular relates to a potato seed cutting machine based on vision recognition and its usage method. Background Technology

[0002] Potatoes are not only a major food crop in my country, but also an important economic crop. In the planting process, the cutting of the seed tubers directly affects the germination rate and survival rate of the tubers, ultimately impacting the overall yield. In the past, farmers relied entirely on manual labor for cutting potatoes, which was both time-consuming and labor-intensive. With the development of agricultural mechanization, potato cutting has gradually been automated, with the aim of increasing the cutting speed, reducing manual labor input, and meeting the needs of large-scale planting.

[0003] However, there are currently two main types of potato seed cutters. One type is based on machine vision to identify the eyes of a whole potato and then cuts it by rotating the blade based on the identification results. The disadvantage of this mode is that it cannot effectively identify the eyes of the whole potato because one side of the potato is always facing down and the eyes on the bottom cannot be identified visually. At the same time, the fixed blade structure cannot adapt to the random distribution of eyes. The other type does not distinguish between potato sizes. It uniformly sorts the potatoes and cuts them in half, then uses machine vision to identify the eyes of the cut pieces and removes the pieces without eyes. The disadvantage of this mode is that it does not distinguish between potato sizes. For larger potatoes, simply cutting them in half is a waste of production resources.

[0004] To address these issues, we provide a vision-based potato seed cutter and its usage method. Summary of the Invention

[0005] The purpose of this invention is to provide a potato seed cutter based on visual recognition and its usage method. Through the coordinated operation of a grading device, a sorting and cutting device, and a bud visual detection and sorting device, the invention solves the problems of incomplete bud detection, waste due to indiscriminate cutting of different sizes, and difficulty in guaranteeing the quality of seed potatoes in existing seed cutters.

The straight cutter and the cross cutter are respectively fixedly installed on the output ends of the two cutting cylinders. The cutting cylinders extend and retract to realize the lifting and cutting of the cutter.

[0010] The invention is further configured to include a potato chunk turning assembly, which includes brush mounting plates fixedly connected to both sides of the second belt conveyor, a brush roller rotatably connected between the two brush mounting plates, a driven pulley fixedly connected to the end of the rotating shaft of the brush roller, a brush motor fixedly mounted inside one of the brush mounting plates, a drive pulley fixedly connected to the output end of the brush motor, and a transmission belt sleeved on the outside of the drive pulley and the driven pulley.

[0011] The invention is further configured such that the detection and sorting assembly includes a main frame fixedly connected to the top of the second support. A camera mounting bracket and a motor mounting plate are fixedly connected to the top inner side of the main frame along the center line. A visual recognition camera for identifying the position and state of potato sprouts is fixedly installed inside the camera mounting bracket. A sorting motor is fixedly installed inside the motor mounting plate, and the output end of the sorting motor is aligned with the transport direction of the second belt conveyor. A sorting turntable for knocking unqualified potatoes into the sorting chute is fixedly connected to the output end of the sorting motor.

[0012] The present invention is further configured such that a conveyor belt cleaning device is provided at the bottom of both the first belt conveyor and the second belt conveyor. The conveyor belt cleaning device includes a conveyor belt cleaning box and a conveyor belt drying box fixedly connected to the bottom of the first belt conveyor or the second belt conveyor. A high-pressure cleaning pipe assembly is fixedly installed inside the conveyor belt cleaning box, and the water nozzle of the high-pressure cleaning pipe assembly is arranged facing the conveyor belt of the conveyor. A drying fan for quickly drying the cleaned conveyor belt is fixedly installed inside the conveyor belt drying box.

[0013] The present invention is further configured such that a main control cabinet, a disinfectant tank and an air compressor are fixedly installed inside the main frame, and the air compressor and the disinfectant tank are both connected to a gas-liquid mixer through sealed pipes to provide a high-pressure gas-liquid mixing medium for the disinfection spray assembly.

[0014] The invention is further configured such that the sorting inclined baffle group adopts a symmetrical louver structure formed by multiple elastic inclined baffles evenly and parallelly arranged. The straight edges of the elastic inclined baffles are fixedly installed on the inner sidewall of the corresponding first side plate or second side plate. The inclined edges of the elastic inclined baffles are uniformly inclined towards the direction of the conveyor belt, and the inclination angle is set to 45 degrees. The middle axis of symmetry of the symmetrically arranged elastic inclined baffles is reserved for the passage of potatoes. Under the elastic guidance of the elastic inclined baffles, the potatoes adjust their posture so that the long axis of the potatoes remains parallel to the direction of the conveyor belt.

[0015] This invention also provides a method for using a potato seed cutter based on visual recognition, which involves cutting potatoes according to the following steps: S1. Feeding and Lifting: Pour the potatoes to be processed into the feeding hopper, start the feeding motor, the feeding motor drives the lower sprocket shaft to rotate through the drive sprocket and drive chain, and then drives the feeding scoop to circulate through the feeding chain, lifting the potatoes from the through-hole upwards, and sliding them down through the guide shell onto the rotating sorting plate of the grading device; S2. Weight Grading: The communication platform scale detects the weight of the potatoes falling on the sorting tray in real time. The rotary servo motor drives the drive shaft to rotate the rotary sorting disc. According to the weight detection result, the potatoes are pushed to the corresponding receiving chute: large potatoes enter the first belt conveyor on the corresponding side, and small potatoes enter the first belt conveyor on the other side. S3. Sequential Arrangement: After the potatoes enter the first belt conveyor, they pass through the sequential inclined baffle group during transportation. Under the guidance of the elastic inclined baffles, the potatoes automatically adjust their posture so that the long axis of the potatoes is parallel to the running direction of the conveyor belt. At the same time, photoelectric sensors detect the position of the potatoes. S4. Quantitative Cutting: When potatoes are transported to the cutting assembly, based on the size grading results, for large potatoes, the cutting cylinder drives the cross cutter downwards to cut them into four pieces; for small potatoes, the cutting cylinder drives the straight cutter to cut them in half; during the cutting process, the disinfection spray assembly mixes disinfectant and compressed air through the air-water mixer, and disinfects the cutter in real time through the disinfection nozzle; S5. Bud detection: The cut potato chunks enter the second belt conveyor. The brush motor of the potato chunk turning component drives the brush roller to rotate, turning the potato chunks and cleaning their surface. The visual recognition camera takes pictures of the passing potato chunks to detect whether there are buds or defects. S6. Defective Product Sorting: The main frame controls the sorting motor based on the detection results of the vision recognition camera. The sorting motor drives the sorting turntable to rotate, knocking out unqualified potato chunks without sprouts or with defects into the sorting chute; qualified potato chunks continue to be conveyed forward with the conveyor belt. S7. Finished Product Output and Cleaning: Qualified potato chunks are output from the end of the second belt conveyor, completing the seed cutting operation; at the same time, the conveyor belt cleaning device is started, the high-pressure cleaning pipe group cleans the conveyor belts of the first and second belt conveyors, and the drying fan dries the cleaned conveyor belts to keep the equipment clean.

[0016] The present invention has the following beneficial effects: 1. This invention uses a communication scale of a grading device to detect the weight of potatoes and associate it with size grading. Combined with a cross-shaped rotating sorting disc driven by a rotary servo motor, potatoes of different sizes can be quickly sent to the corresponding conveying channels, avoiding uneven cutting caused by mixing of sizes, ensuring the quality of seed potato cuttings, and avoiding waste.

[0017] 2. The present invention uses a symmetrical louvered elastic inclined baffle structure of the sorting inclined baffle group to guide and sort the potatoes in the conveying process, so that the potatoes enter the cutting and inspection process in a uniform posture, avoiding problems such as skewing of the cutting and omission of the eye detection caused by chaotic posture, and reducing potato collision damage.

[0018] 3. The present invention drives the brush roller to rotate through the brush motor of the potato tuber turning component, which can turn the potato tubers over during the conveying process, avoid missing the bud eye detection, and clean the soil and impurities on the surface of the potato, preventing impurities from blocking the bud eyes and affecting the detection accuracy, thereby further improving the comprehensiveness and accuracy of bud eye detection.

[0019] 4. This invention uses a visual recognition camera in the sorting component to quickly identify the position and status of potato buds. Combined with a sorting turntable driven by a sorting motor, it can quickly respond and knock unqualified seed potatoes with damaged or no buds into the sorting chute for discharge, thus screening qualified seed potatoes, ensuring seed potato quality, and improving the germination rate and survival rate of subsequent planting.

[0020] 5. This invention uses a high-pressure cleaning pipe assembly and a drying fan in conjunction with a conveyor belt cleaning device to clean and dry the conveyor belts of the first and second belt conveyors in real time. This removes residual mud, potato residue, disinfectant, and other impurities from the conveyor belts, preventing contamination of the potatoes being transported subsequently. It also prevents the conveyor belts from becoming wet and slippery, thus preventing bacterial growth, extending the service life of the equipment, and ensuring the stability of seed potato quality.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1, please refer to Figures 1 to 10The present invention is a potato seed cutter based on visual recognition, including a main frame 100 and a base frame 101. The top of the base frame 101 is fixedly connected from left to right to a platform frame 102, a first support 103 and a second support 104, and the first support 103 and the second support 104 are arranged in a descending stepped manner. The feeding device 200 includes a vertical frame 201 fixedly connected to one end of the base frame 101. A feeding hopper 202 is fixedly installed on the side of the vertical frame 201 away from the base frame 101.

The feeding hopper 202 can realize the batch storage of potatoes and realize automatic and orderly feeding. The grading device 300 includes a communication platform scale 301 fixedly installed on the top of the platform scale frame 102. A triangular sorting bracket 302 is fixedly connected to the top of the communication platform scale 301. A mounting base 303 and a rotary servo motor 305 are fixedly connected to the inclined surface of the sorting bracket 302 facing the upright frame 201. A drive shaft 304 is rotatably connected inside the mounting base 303. The bottom end of the drive shaft 304 is fixedly connected to the output end of the rotary servo motor 305. A device for grading potatoes by size is fixedly connected to the top of the drive shaft 304. The cross-shaped rotating sorting disc 306 and the communication scale 301 can detect the weight of potatoes, realize the correlation between weight and size for grading, provide data for subsequent cutting specifications, and transmit the detection data to the control system. The rotating servo motor 305 drives the rotating sorting disc 306 to rotate smoothly through the drive shaft 304. The cross-shaped rotating sorting disc 306 can quickly send potatoes of different sizes to the corresponding first belt conveyor 401, avoid the mixing of sizes and specifications, and ensure the quality of seed potato cuttings. The sorting and cutting device 400 includes two first belt conveyors 401 fixedly installed on the top of the first support 103. The two first belt conveyors 401 respectively transport large-sized potatoes and small-sized potatoes after grading. First side plates 402 are fixedly connected to both sides of the two first belt conveyors 401. On opposite sides of the two inner first side plates 402, receiving chutes 403 are fixedly connected for receiving potatoes after grading by the rotating sorting disc 306. Photoelectric sensors 404 for detecting the position of the potatoes are installed on the outer side of the first side plates 402. The top of the first support 103 corresponds to the two first belt conveyors 401. The belt conveyor 401 is equipped with two cutting components 407. The two cutting components 407 are respectively equipped with a cross cutter 409 for cutting potatoes into four pieces and a straight cutter 408 for cutting potatoes into two pieces. The receiving chute 403 can guide the potatoes after being graded by the rotating sorting disc 306 to fall accurately into the first belt conveyor 401, reducing potato collision damage. The photoelectric sensor 404 can accurately detect the position of the potatoes and trigger the cutting components 407 to act in time. The corresponding setting of the cross cutter 409 and the straight cutter 408 can flexibly adjust the number of pieces according to the potato specifications to adapt to the planting needs of different seed potatoes. The bud eye visual inspection and sorting device 500 includes two second belt conveyors 501 fixedly installed on the top of a second support 104. Second side plates 502 are fixedly connected to both sides of each second belt conveyor 501.

The top of the second support 104 is equipped with a device for detecting the bud eye status of potatoes and discharging substandard potatoes. The potato detection and sorting component 508 consists of two second belt conveyors 501 that receive the diced potatoes conveyed by the two first belt conveyors 401, achieving seamless connection between dicing and detection and sorting. The sorting chute 503 can quickly discharge unqualified potatoes, and the sorting inclined baffle 504 guides unqualified potatoes to slide smoothly into the sorting chute 503. The detection and sorting component 508 can identify the position and condition of potato buds and quickly sort out unqualified seed potatoes such as those with damaged buds or no buds, ensuring seed potato quality and improving the germination rate and survival rate of subsequent planting. Between the two oppositely arranged first side plates 402 and between the two oppositely arranged second side plates 502, there are sorting inclined baffle groups 1100 for guiding and sorting the potatoes. The sorting inclined baffle groups 1100 can adjust and sort the potatoes during the conveying process, ensuring that the potatoes enter the cutting and inspection process in a uniform posture, avoiding problems such as skewed cutting and missed eye detection due to chaotic posture, improving cutting accuracy and inspection accuracy, and reducing mutual collisions between potatoes during the conveying process, thus reducing the damage rate.

[0036] Specifically, the output end of the feeding motor 205 is fixedly connected to a drive sprocket 206. A driven sprocket 204 and a lower feeding sprocket 209 are fixedly connected to the outside of the lower sprocket shaft 203. A drive chain 207 is sleeved on the outside of the driven sprocket 204 and the drive sprocket 206. An upper feeding sprocket 211 is fixedly connected to the outside of the upper sprocket shaft 210. A feeding chain 212 is sleeved on the outside of the upper feeding sprocket 211 and the lower feeding sprocket 209, and the feeding chain 212 passes through the passage 202a. Multiple feeding scoops 213 for lifting potatoes are fixedly installed at equal intervals along the circumferential direction on the outer surface of the feeding chain 212. The upright frame 20... 1. A guide shell 214 for guiding the material to fall is fixedly connected to the top. The feeding motor 205 drives the lower sprocket shaft 203 to rotate through the active sprocket 206, the drive chain 207 and the driven sprocket 204. In turn, the lower feeding sprocket 209, the feeding chain 212 and the upper feeding sprocket 211 drive the upper sprocket shaft 210 to rotate synchronously, ensuring that the feeding scoop 213 lifts the potatoes at a uniform speed. The feeding scoops 213 are set at equal intervals to achieve uniform feeding of potatoes and avoid batch accumulation. The guide shell 214 can guide the potatoes lifted by the feeding scoop 213 to fall into the grading device 300 and prevent the potatoes from falling outside the equipment. The slitting assembly 407 includes a gantry frame 407a. A cutting cylinder 407b is fixedly installed on the outside of the gantry frame 407a. A straight cutter 408 and a cross cutter 409 are respectively fixedly installed on the output ends of the two cutting cylinders 407b. The cutting cylinders 407b extend and retract to lift and cut the cutter. Multiple disinfection spraying assemblies 411 are arranged around the outside of the gantry frame 407a along the circumference of the cutter for real-time disinfection of the straight cutter 408 and the cross cutter 409. The cutting cylinders 407b drive the cutter to lift and retract, and the cutter stroke can be flexibly adjusted according to the potato specifications to meet the needs of cutting potato pieces of different sizes. The disinfection spraying assemblies 411 are arranged around the circumference of the cutter to disinfect the straight cutter 408 and the cross cutter 409 in real time, avoiding the cutter from carrying pathogens and contaminating the seed potato, reducing the incidence of seed potato diseases, and ensuring the quality of the seed potato. It also includes a potato tuber turning assembly 507, which includes brush mounting plates 507a fixedly connected to both sides of the second belt conveyor 501. A brush roller 507d is rotatably connected between the two brush mounting plates 507a. A driven pulley 507e is fixedly connected to the end of the rotating shaft of the brush roller 507d. A brush motor 507b is fixedly mounted inside one of the brush mounting plates 507a. The output end of the brush motor 507b is fixedly connected to a drive pulley 507c. A drive belt 507f is fitted around the pulley 507c and the driven pulley 507e. The brush motor 507b drives the brush roller 507d to rotate through the drive pulley 507c, the drive belt 507f and the driven pulley 507e. The brush roller 507d can cause the potatoes to tumble on the second belt conveyor 501 to avoid missing the bud detection and improve the detection accuracy. At the same time, the brush roller 507d can clean the soil and impurities on the surface of the potatoes to prevent impurities from blocking the buds and affecting the detection accuracy. The detection and sorting assembly 508 includes a main frame 508a fixedly connected to the top of the second support 104. A camera mounting bracket 508b and a motor mounting plate 508d are fixedly connected along the centerline of the top inner side of the main frame 508a. A visual recognition camera 508c for identifying the position and state of potato sprouts is fixedly installed inside the camera mounting bracket 508b. A sorting motor 508e is fixedly installed inside the motor mounting plate 508d, and the output end of the sorting motor 508e is connected to the second belt conveyor 501. The feeding direction remains consistent. The output end of the sorting motor 508e is fixedly connected to a sorting turntable 508f, which is used to knock unqualified potatoes into the sorting chute 503. The visual recognition camera 508c can quickly identify the position and status of potato sprouts and provide signals for sorting. The sorting motor 508e drives the sorting turntable 508f to rotate, which can quickly knock unqualified potatoes into the sorting chute 503. The sorting response is rapid, and the structural design of the sorting turntable 508f will not damage qualified potatoes. The aligning inclined baffle group 1100 adopts a symmetrical louver structure formed by multiple elastic inclined baffles 1101 evenly and parallelly arranged. The straight edges of the elastic inclined baffles 1101 are fixedly installed on the inner wall of the corresponding first side plate 402 or second side plate 502. The inclined edges of the elastic inclined baffles 1101 are uniformly inclined towards the direction of the conveyor belt, and the inclination angle is set to 45 degrees. A channel for potatoes to pass through is reserved at the middle axis of symmetry of the symmetrically arranged elastic inclined baffles 1101. The potato's posture is adjusted by the elastic guiding action of the plate 1101, keeping the long axis of the potato parallel to the running direction of the conveyor belt. The symmetrical louvered structure of the sorting inclined baffle group 1100 can adaptively guide potatoes of different sizes. The elastic action of the elastic inclined baffle 1101 can avoid hard damage to the potato, while flexibly adjusting the potato's posture to ensure that the cutter can be aligned with the center of the potato during subsequent dicing, improving the uniformity of the dicing, and facilitating the visual recognition camera 508c to fully detect the eyes.

[0037] The operation process of this embodiment is as follows: When the potato seed cutter is needed, the potatoes to be cut are first placed in batches into the feeding hopper 202. Then, the feeding motor 205 is started, which drives the driven sprocket 204 to rotate through the drive sprocket 206 and drive chain 207, thereby driving the lower sprocket shaft 203 to rotate synchronously. The lower feeding sprocket 209 on the lower sprocket shaft 203 drives the upper feeding sprocket 211 and upper sprocket shaft 210 to rotate through the feeding chain 212. The feeding scoop 213 on the feeding chain 212 rotates with the chain, scooping up the potatoes in the feeding hopper 202 one by one. After being raised to the top of the stand 201, the potatoes slide down from the guide shell 214 and fall onto the rotating sorting disc 306 of the grading device 300. The communication scale 301 detects the weight of the potatoes falling into the corresponding area of ​​the rotating sorting disc 306 in real time and transmits the weight data to the control system. The control system controls the rotating servo motor 305 to start according to the preset weight grading standard. The rotating sorting disc 306 is driven to rotate through the drive shaft 304, and potatoes of different weights are transferred to the corresponding receiving chute 403. The potatoes are then guided by the receiving chute 403 onto the two first belt conveyors 401. When potatoes are conveyed on the first belt conveyor 401, the sorting inclined baffle group 1100 between the first side plates 402 on both sides guides the posture of the potatoes, making the long axis of the potatoes parallel to the running direction of the first belt conveyor 401, thus achieving sorting. When the photoelectric sensor 404 detects that the potatoes have moved directly under the cutting component 407, it sends a signal to the control system. The control system triggers the cutting cylinder 407b to move, driving the corresponding cutter (the cross cutter 409 for large potatoes and the straight cutter 408 for small potatoes) to descend, completing the potato cutting. At the same time, the disinfection spray component 411 disinfects the cutter in real time to avoid bacterial contamination. The cut potatoes are then conveyed by the first belt conveyor 401 to the corresponding second belt conveyor 501, which then starts. The tubers are conveyed forward. At this time, the brush motor 507b of the tuber turning component 507 starts, which drives the driven pulley 507e and brush roller 507d to rotate through the active pulley 507c and the transmission belt 507f. The brush roller 507d turns the tubers over and cleans the impurities on the surface of the tubers. When the tubers run to the bottom of the detection and sorting component 508, the vision recognition camera 508c starts, takes an image of the tubers and identifies the position and status of the buds. If the tubers are found to have damaged buds or no buds, the control system controls the sorting motor 508e to start, which drives the sorting turntable 508f to rotate and knock the unqualified tubers into the sorting chute 503. The unqualified tubers are then guided out of the equipment by the sorting inclined baffle 504. The qualified tubers continue to be conveyed by the second belt conveyor 501, completing the whole process of cutting, detection and sorting.

[0038] Example 2, please refer to Figure 6 and Figure 10Based on the first specific embodiment, the disinfection spray assembly 411 includes an air-water mixer 411a fixedly connected to the outside of the gantry frame 407a. An adjustable-angle disinfection joint tube 411b is fixedly installed at the output end of the air-water mixer 411a. A disinfection nozzle 411c for achieving uniform spraying is fixedly installed at the free end of the disinfection joint tube 411b. The air-water mixer 411a can fully mix the disinfectant with air to form a high-pressure air-liquid mixture, which enhances the impact force and coverage of the disinfection spray. The adjustable-angle disinfection joint tube 411b can flexibly adjust the spray angle of the disinfection nozzle 411c according to the specifications and installation position of the cutter, so that the spray range covers all parts of the cutter and avoids disinfection dead corners. The disinfection nozzle 411c achieves uniform spraying of disinfectant, which not only ensures the disinfection effect but also avoids waste of disinfectant and reduces the cost of use.

[0039] Specifically, the main frame 100 is internally equipped with a main control cabinet 700, a disinfectant tank 800, and an air compressor 900. The air compressor 900 and the disinfectant tank 800 are both connected to the air-water mixer 411a through sealed pipes to provide a high-pressure air-liquid mixing medium for the disinfection spray assembly 411. The air compressor 900 provides high-pressure air, which mixes with the disinfectant to form a high-pressure spray medium, ensuring sufficient pressure for disinfection spray and improving the disinfection effect.

[0040] The operation process of this embodiment is as follows: When the cutter needs to be disinfected, the air compressor 900 is started first. The high-pressure air generated by the air compressor 900 and the disinfectant output from the disinfectant tank 800 are transported to the air-water mixer 411a through a sealed pipe. The air-water mixer 411a mixes the two thoroughly to form a high-pressure air-liquid mixed disinfection medium. The mixed disinfection medium is transported to the disinfection nozzle 411c through the disinfection joint tube 411b. According to the installation position and specifications of the straight cutter 408 and the cross cutter 409, the angle of the disinfection joint tube 411b is adjusted so that the spray range of the disinfection nozzle 411c completely covers all parts of the cutter, avoiding disinfection dead corners. During the entire process of the cutting cylinder 407b driving the cutter to complete the cutting and resetting, the disinfection spray assembly 411 continues to work. The disinfection nozzle 411c sprays the high-pressure air-liquid mixed medium evenly on the surface of the cutter, thoroughly removing the potato residue and bacteria remaining on the cutter, realizing real-time disinfection, and at the same time preventing potato pieces from sticking to the cutter.

[0041] Example 3, please refer to Figures 7 to 9Based on specific embodiments one and two, both the first belt conveyor 401 and the second belt conveyor 501 are equipped with a conveyor belt cleaning device 600 at their bottoms. The conveyor belt cleaning device 600 includes a conveyor belt cleaning box 601 and a conveyor belt drying box 602 fixedly connected to the bottom of the first belt conveyor 401 or the second belt conveyor 501. A high-pressure cleaning pipe assembly 603 is fixedly installed inside the conveyor belt cleaning box 601, with the water nozzles of the high-pressure cleaning pipe assembly 603 facing the conveyor belt. A drying fan 6 is fixedly installed inside the conveyor belt drying box 602 for quickly drying the cleaned conveyor belt. 04. The conveyor belt cleaning device 600 can clean and dry the conveyor belts of the first belt conveyor 401 and the second belt conveyor 501 in real time, avoiding contamination of the potatoes transported subsequently by impurities such as residual mud, potato residue, and disinfectant on the conveyor belt, thus ensuring the quality of seed potatoes. The water nozzles of the high-pressure cleaning pipe group 603 are directed towards the conveyor belt, which can use high-pressure water flow to thoroughly remove stubborn impurities on the conveyor belt. The drying fan 604 in the conveyor belt drying box 602 can quickly dry the cleaned conveyor belt, preventing the potatoes from slipping and sticking due to the wet surface of the conveyor belt. At the same time, it can prevent bacteria from growing in a humid environment, extend the service life of the conveyor belt, and ensure the long-term stable operation of the equipment.

[0042] The operation process of this embodiment is as follows: When the conveyor belt of the first belt conveyor 401 reaches the bottom, it enters the conveyor belt cleaning box 601. The high-pressure cleaning pipe group 603 inside the conveyor belt cleaning box 601 is activated, and the water nozzle sprays high-pressure water towards the surface of the conveyor belt to wash away the potato residue, soil, and disinfectant residue from the disinfection spray, thus achieving real-time cleaning of the conveyor belt. After cleaning, the conveyor belt continues to run and enters the conveyor belt drying box 602. The drying fan 604 inside the conveyor belt drying box 602 is activated to blow hot air onto the surface of the conveyor belt, quickly drying the moisture on the surface of the conveyor belt. This prevents the potatoes from slipping and sticking due to the damp surface of the conveyor belt, and also prevents bacteria from growing in the damp environment, extending the service life of the conveyor belt. The conveyor belt cleaning device 600 at the bottom of the second belt conveyor 501 works in the same way to clean and dry the conveyor belt of the second belt conveyor 501 in real time, ensuring that the conveyor belt is clean throughout the process, avoiding impurities from contaminating the cut potato pieces, and further ensuring the quality of the seed potatoes.

At the same time, the photoelectric sensor 404 detects the position of the potatoes. S4. Quantitative Cutting: When potatoes are transported to the cutting component 407, according to the size grading results, for large potatoes, the cutting cylinder 407b drives the cross cutter 409 to move downwards and cut them into four pieces; for small potatoes, the cutting cylinder 407b drives the straight cutter 408 to cut them in half; during the cutting process, the disinfection spray component 411 mixes disinfectant and compressed air through the air-water mixer 411a, and disinfects the cutter in real time through the disinfection nozzle 411c; S5. Bud detection: The cut potato chunks enter the second belt conveyor 501. The brush motor 507b of the potato chunk turning component 507 drives the brush roller 507d to rotate, turning the potato chunks and cleaning their surfaces. The visual recognition camera 508c takes pictures of the passing potato chunks to detect whether there are buds or defects. S6. Defective Product Sorting: The main frame 508a controls the sorting motor 508e to operate based on the detection results of the vision recognition camera 508c.
