Furthermore, the bud eye recognition unit identifies the position of the bud eyes on each seed potato and adjusts the angle of the cutting blade on the cutting unit according to the position of the bud eyes. This allows the cutting blade to be adjusted to the position required for the cutting operation, thus effectively solving the problem that it is difficult to achieve mechanization and automation of seed potato cutting operation due to the difficulty in effectively fixing the seed potatoes and the random distribution of the bud eyes on the seed potatoes. This system effectively achieves mechanization and automation of seed potato cutting operation.

[0076] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of the present invention, but not all embodiments.

[0077] We know that because potatoes vary in size and specifications, they need to be graded according to their size before cutting to facilitate subsequent cutting. Furthermore, since the shape and size of potatoes are often irregular, there is always the problem of fixing the seed potatoes during the cutting process in the automated cutting operation. At the same time, in order to improve the continuity and efficiency of the operation, it is necessary to consider the continuous conveying and cutting of seed potatoes. This results in the fact that some existing mechanized cutting equipment is often very complex in structure and inconvenient to operate.

[0078] To address the above problems, in some embodiments of the present invention, reference is made to... Figure 1 , Figure 2 and Figure 3 Seed potato cutting system, including:

[0079] The seed potato grading system is used to sort seed potatoes according to their specifications and size, and then send the sorted seed potatoes to the corresponding seed potato cutting system.

[0080] A seed potato cutting system, wherein multiple seed potato cutting systems are arranged side by side on one side of the seed potato grading system.

[0081] Reference Figure 4 , Figure 5 and Figure 6 The seed potato cutting system includes:

[0082] The conveying platform 10 includes a transmission unit, which comprises a transmission drive assembly, a transmission wheel set, and a transmission component mounted on the transmission wheel set. The transmission drive assembly drives the transmission wheel set to rotate and causes the transmission component to rotate cyclically. Multiple positioning components 11 are arranged side-by-side along the circumferential direction of the transmission component. Each positioning component 11 has multiple outwardly opening positioning grooves 111 on one or both sides. (Refer to...) Figure 8 The positioning grooves 111 are spaced apart along the length of the positioning member, and the two positioning grooves 111 arranged opposite to each other on two adjacent positioning members 11 can form a closed seed potato groove 12 for setting seed potatoes.

[0083] Reference Figure 5The transmission wheel assembly includes a driving sprocket assembly 101 and a driven sprocket assembly 102. The transmission components include two opposing transmission chains 104, which are respectively connected to the driving and driven sprocket assemblies. Thus, when the driving and driven sprocket assemblies are driven to rotate by the transmission drive assembly, the transmission chains can be driven to move. The transmission drive assembly can be a transmission motor 103, which drives the driving and driven sprocket assemblies to rotate, thereby driving the transmission wheel assembly.

[0084] The positioning component 11 is fixedly connected to two transmission chains 104 at both ends. When the transmission chains move, they drive the positioning component to rotate circumferentially.

[0085] Of course, the transmission components here can also adopt other structural forms, such as belts; correspondingly, the transmission pulley set can adopt the structure of a transmission roller set, which drives the belt to move. Fixing the positioning component on the belt can also achieve the same driving effect.

[0086] Reference Figure 6 Positioning components 11 are arranged side-by-side along the circumferential direction of the transmission component. Through adjacent positioning components and the positioning grooves provided on the positioning components, multiple rows of seed potato troughs are formed on the conveying platform. Here, the column direction is along the width of the conveying platform and the row direction is along the conveying direction of the conveying platform. The continuously driven positioning components can form a multi-column, multi-row, array-distributed seed potato trough on the conveying platform, which can realize the positioning of seed potatoes in the seed potato trough while realizing the continuous conveying of seed potatoes.

[0087] In some embodiments, the size of the positioning groove is determined according to the specifications and size of the seed potato, so that the seed potato can be precisely placed in the seed potato groove for effective positioning. Therefore, the seed potatoes entering the conveying platform can usually be screened to separate seed potatoes of a specified size. After screening, seed potatoes of the corresponding specifications and sizes are sent to the conveying platform for subsequent cutting operations to ensure the quality and reliability of the cutting operation. The positioning groove can be set as a semi-circular groove with a bottom and arc-shaped sidewalls to facilitate the cutting operation of the seed potatoes in the positioning groove 111.

[0088] In some embodiments, the positioning element and the transmission element are detachably connected to facilitate the disassembly and replacement of the positioning element. This allows the positioning element with a corresponding positioning groove to be configured on the conveying platform according to the specifications and size of the seed potatoes to be processed.

[0089] When the positioning member is in a horizontal state, the positioning members 11 form a tight fit. Since the positioning member will rotate relative to the transmission member during the movement, in order to avoid interference between the positioning members during the operation, the positioning member 11 is set to be arc-shaped on both sides. For example, the positioning member 11 is set to be a structural member with an arc-shaped cross section.

[0090] The structure, consisting of positioning grooves on two positioning members forming the seed potato troughs, reduces the width of the positioning members, making them well-suited for the transmission method of the conveyor platform and enabling continuous conveying and transmission. Furthermore, based on this structure, as seed potatoes are fed into the troughs from the inlet of the conveyor platform, the distance between adjacent positioning members decreases as they move from the end of the platform to a horizontal position. This allows for clamping of the seed potatoes within the troughs by the adjacent positioning members, ensuring better positioning and fixation. Similarly, at the outlet of the conveyor platform, the distance between adjacent positioning members increases as they move from a horizontal position towards the outlet. This releases the clamping and fixing effect on the seed potatoes, allowing the cut seed potatoes to detach from the troughs and separate from the conveyor platform under gravity.

[0091] In some embodiments, a guiding unit is provided at the entrance end of the conveying platform. The guiding unit includes guide partitions 13 respectively disposed on both sides of each positioning slot, and adjacent guide partitions 13 form a conveying channel arranged along the conveying direction of the conveying platform. In this way, seed potatoes entering from the entrance end of the conveying platform are sequentially distributed into each conveying channel in the conveying direction under the action of the guiding unit and the positioning element, and thus sequentially distributed into each seed potato slot.

[0092] Each guide baffle is connected by a fixed frame plate 14, and the guide unit is fixedly installed above the conveying platform by the fixed frame plate.

[0093] Based on the aforementioned structural features of the conveying platform, continuous conveying and distribution of seed potatoes, as well as positioning of seed potatoes during the cutting operation, are realized. The simple structure forms the basis for the mechanization and automation of the cutting operation in this invention, and plays an important role in realizing the mechanization and automation of this invention.

[0094] In some embodiments of the present invention, the seed potato cutting system includes a bud eye recognition unit 20, which is disposed above the conveying platform and is used to identify the position of the bud eyes on the seed potatoes on the conveying platform.

[0095] The bud identification unit 20 can employ a light source and a camera. When the seed potatoes on the conveying platform are conveyed and pass through the bud identification unit, images of the seed potatoes are captured by the camera. Based on existing image processing methods and image recognition models, the buds on the seed potatoes can be identified, thereby determining their positions. This invention does not involve improvements to image processing methods, image recognition models, or algorithms for calculating bud positions based on image recognition models. Existing processing methods can be used to identify buds and calculate their positions from images of the seed potatoes, and these will not be elaborated upon here.

[0096] Reference Figure 4 The bud recognition unit can be a box set above the conveying platform, with a light source and camera installed inside the box to improve the quality of the acquired images.

[0097] In some embodiments of the present invention, reference is made to Figure 9 , Figure 10 and Figure 11 The seed potato cutting system includes a cutting unit 30, which is located above the conveying platform and includes a cutting drive assembly and a cutting blade unit.

[0098] The cutting unit includes a blade plate 304 and at least one row of cutting assemblies disposed on the blade plate. The cutting assembly includes a cutting motor 305 disposed on the blade plate and a cutting blade 306 connected to the rotating shaft of the cutting motor. The position of the cutting blade corresponds to the position of one or more rows of seed potato troughs formed on the conveying platform. The cutting drive assembly is used to drive the cutting unit to move in the vertical direction.

[0099] In coordination with the arrangement of seed potato troughs on the conveyor platform, the cutting unit arranges the cutting blades in rows on the blade plate, ensuring that each blade corresponds to a position in a seed potato trough. Typically, the cutting unit includes multiple rows of cutting blades, enabling the cutting of multiple rows of seed potatoes at once, thus improving cutting efficiency. Figure 11 As shown, the cutters form a 6×6 array on the blade plate, and each cutter is controlled by a corresponding cutter motor. Based on the obtained position of the bud eye of the seed potato, the cutter motor is controlled to rotate, driving the corresponding cutter to the angle required for dicing, thus accommodating dicing operations with bud eyes at different positions.

[0100] In some embodiments, the cutter 306 can be configured as an I-shaped structure consisting of three blades, so that each seed potato can be cut into four pieces during the cutting operation.

[0101] In some embodiments, a support component is provided above the conveying platform, which may be a support plate 15 provided on both sides of the conveying platform;

[0102] The cutting drive assembly includes a mounting plate 302, a cylinder 301 mounted on the mounting plate, and a fixing plate 303 mounted on the piston rod of the cylinder. The mounting plate 302 is mounted on a support plate, and the cutting assembly is mounted on the fixing plate 303. The cylinder drives the fixing plate to move vertically, thereby driving the cutting assembly connected to the fixing plate to move vertically, thus realizing the cutting operation of seed potatoes.

[0103] A guide post can be provided between the fixed plate 303 and the mounting plate 302 to guide the movement of the fixed plate in the vertical direction, so as to ensure the movement accuracy of the cutter in the cutting operation.

[0104] In some embodiments, a space for accommodating the cutter motor is formed between the blade plate and the fixing plate. For example, a bracket can be provided on the blade plate, and the fixing plate can be connected to the bracket. The bracket forms a certain space between the blade plate and the fixing plate to accommodate the cutter motor, so as to facilitate the installation of the cutter motor in the cutter unit.

[0105] In some embodiments, a cutter disinfection unit 40 for disinfecting the cutter is provided above the conveying platform;

[0106] The mounting plate 302 is slidably mounted on the support assembly, enabling the mounting plate to move along the conveying direction of the conveying platform. A sliding drive assembly for driving the mounting plate to slide on the support assembly is provided between the mounting plate and the support assembly.

[0107] Reference Figure 12 The cutter disinfection unit 40 can be a disinfection tank 401 fixedly installed above the conveying platform. Disinfectant is placed in the disinfection tank 401. When disinfection is required, the cutter assembly is moved above the disinfection tank, and then the cutter assembly is controlled to move downward and immerse in the disinfectant to disinfect the cutter.

[0108] The disinfection tank can be equipped with pipes and nozzles to disinfect the cutting blades by spraying them.

[0109] Disinfectants can be 5% potassium permanganate solution or 75% alcohol.

[0110] A waste liquid discharge unit can also be installed on the disinfection tank to facilitate the discharge of waste liquid. Similarly, a liquid supply unit can also be installed to supply disinfectant solution into the disinfection tank.

[0111] The sliding fit between the mounting plate and the support assembly can be achieved by setting a linear guide assembly 31 on the support assembly and connecting the mounting plate to the slider on the linear guide assembly.

[0112] The sliding drive assembly can be configured by mounting a geared motor 32 on a mounting plate, mounting a transmission gear on the geared motor, and mounting a matching transmission rack on the linear guide assembly. Through the cooperation between the transmission gear and the transmission rack, the cutter unit is driven to move along the conveying direction of the conveying platform.

[0113] In some embodiments, the seed potato cutting system includes a control unit for controlling the cutter motor according to the identified bud position on the seed potato, so that the cutter rotates to the desired angle.

[0114] Meanwhile, the control unit can also be used to control the cutting drive component to realize the cutting operation of seed potatoes; and to control the motion of the conveying platform to realize the continuous conveying of seed potatoes; and to control the sliding drive component to realize the disinfection operation of the cutter.

[0115] In the seed potato cutting system of the present invention, the specifications and sizes of the seed potato troughs of the conveying platform are different in different seed potato cutting systems, and the specifications and sizes of the seed potato troughs are matched with the specifications and sizes of the seed potatoes being fed in.

[0116] This invention uses a seed potato grading system to sort seed potatoes according to specifications and size, and then sends them to different seed potato cutting systems. By configuring multiple matching seed potato cutting systems, seed potatoes of different specifications and sizes can be cut into pieces, thus realizing the cutting operation of seed potatoes of different specifications and sizes.

[0117] The seed potato cutting system employs positioning components with positioning grooves to form rows of seed potato troughs on the conveying platform. This allows the conveying platform to distribute the seed potatoes entering the platform into each trough during operation, thus positioning the seed potatoes on the platform. Furthermore, a bud recognition unit identifies the position of the buds on each seed potato and adjusts the angle of the cutting blade on the cutting unit based on the bud position. This effectively solves the problem of difficulty in effectively fixing seed potatoes and the random distribution of buds, which hinders the mechanization and automation of seed potato cutting. Therefore, the system effectively achieves mechanization and automation of seed potato cutting.

[0118] In some embodiments, refer to Figure 1 , Figure 13 and Figure 14 The seed potato grading system includes:

[0119] Feeding unit 50, the feeding unit is used to feed seed potatoes to screening unit;

[0120] Screening unit 60 is used to screen out impurities in seed potatoes and send the screened seed potatoes to grading unit;

[0121] The grading unit 70 is used to sort seed potatoes according to their specifications and size, and send the sorted seed potatoes into the corresponding seed potato cutting system, which is arranged side by side on one side of the grading unit.

[0122] The feeding unit 50 can adopt an existing conveyor belt or similar structure, which can lift the seed potatoes in the hopper to the position of the screening unit and feed them into the screening unit.

[0123] Reference Figure 14 , Figure 17 and Figure 18 The screening unit 60 includes a screening support 601, screening components 602 arranged sequentially at intervals along the axial direction of the screening support, and a screening drive component (not shown in the figure).

[0124] The screening assembly 602 includes a screening roller shaft 621 and a screening wheel assembly mounted on the screening roller shaft. The two ends of the screening roller shaft 621 are rotatably connected to the screening support 601. The screening wheel assembly includes a plurality of screening wheels 622 mounted side by side on the screening roller shaft. Each screening wheel 622 includes a plurality of screening blades 6221 arranged along its circumferential direction. The screening blades 6221 may be made of rubber.

[0125] When the screening wheel group rotates, the seed potatoes located between the screening wheels are turned over by the screening blades and continuously conveyed forward in the direction of rotation, thereby achieving the removal of impurities and conveying of the seed potatoes.

[0126] The screening drive assembly is used to drive all screening components to rotate in the same direction. The screening drive assembly can be a screening motor, which drives one of the screening rollers to rotate and connects this screening roller to the other screening rollers via chain drive, thereby achieving simultaneous transmission of the screening components.

[0127] Reference Figure 14 , Figure 15 and Figure 16 The grading unit 70 includes a grading bracket 701, grading components 702 and a grading drive component (not shown in the figure) arranged sequentially and at intervals along the axial direction of the grading bracket;

[0128] The grading assembly 702 includes a grading roller 721 and a grading wheel assembly disposed on the grading roller 721. Both ends of the grading roller 721 are rotatably connected to the grading bracket 701.

[0129] The graded drive assembly is used to drive each graded assembly to rotate in the same direction.

[0130] The grading unit forms different grading areas corresponding to different seed potato cutting systems. The grading components in different grading areas are set with different spacings, and the spacing between the grading components in each grading area gradually increases along the conveying direction of the seed potato in the grading unit.

[0131] A grading hopper 703 is installed at the corresponding position of each grading area. The grading hopper 703 is located below the grading component. Seed potatoes are sent into the conveying platform of the seed potato cutting system through the grading hopper.

[0132] The grading wheel assembly includes multiple grading wheels 722 arranged side by side on the grading roller shaft. Each grading wheel 722 includes multiple grading rods 7221 arranged along its circumferential direction. The grading rods 7221 may be made of rubber.

[0133] When the grading wheel group rotates, the seed potatoes are continuously conveyed forward in the direction of rotation. During this process, due to the different spacing between the grading components corresponding to different grading areas, the seed potatoes of the corresponding specifications will fall into the corresponding grading hopper when they enter the corresponding grading area during the conveying process, thereby realizing the grading operation of the seed potatoes.

[0134] In some embodiments, the seed potato grading system includes:

[0135] Diseased potato identification unit 61 is located above screening unit 60 and is used to identify the state of seed potatoes on screening unit. Diseased potato identification unit can adopt a similar structure and principle as bud identification unit, which will not be described in detail here. The state of seed potato generally refers to the surface state of seed potato, such as whether there are defects such as rot or large-area damage on the surface.

[0136] Sorting unit 62 is used to sort seed potatoes on the screening unit; the sorting unit can be a robotic arm;
