DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0028] Example 1: This embodiment provides an automatic cutting device for cutting potato seeds, specifically Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 As shown, it includes an introduction transmission system 10, a seed cutting system 20, and a discharge transmission system 30. The introduction transmission system 10 transports seed potatoes to the seed cutting system 20, and the seed cutting system 20 cuts the seed potatoes into pieces and transports them to the discharge transmission system 30. The discharge transmission system 30 transports the cut seed potatoes out. The seed cutting system 20 includes: The transport unit is used to receive the seed potatoes from the introduction conveyor system 10 and transport the seed potatoes to the discharge conveyor system 30. The transport unit includes a transmission shaft 222 and multiple conveyor rollers. A third sprocket 215 is mounted on the transmission shaft 222, and two third sprockets 215 are synchronously driven by a conveyor chain. Connectors are mounted at both ends of the conveyor rollers, and the connectors are connected to the conveyor chain. The conveyor rollers include a roller shaft 221 and a limit plate 207. Multiple limit plates 207 are mounted on the roller shaft 221. The cutting part is used to cut the seed potatoes on the transport part into pieces; the cutting part includes a cutting roller 204, on which a plurality of circular blades are evenly spaced; the cutting position of the blades is between two limiting pieces 207; A driving part, used to provide driving force to the transport part and the cutting part; The mounting frame is used for installing the transport unit, the cutting unit and the driving unit; the transmission shaft 222 and the cutting roller 204 are both rotatably connected to the mounting frame, and the driving unit is respectively connected to the transmission shaft 222 and the cutting roller 204 in a transmission manner.

[0029] During use, the seed potatoes are placed on the introduction conveying system 10, which transports them to the transport section. At this time, the seed potatoes are distributed in the gap between the two conveying rollers. As the drive shaft 222 rotates, the rows of seed potatoes begin to approach the cutting section. When the seed potatoes are below the cutting section, they are stuck between the two conveying rollers, so they are pushed and then cut into two by the rotating blades. They are then discharged by the transport section and fall onto the discharge conveying system 30, and are then transferred to the next workstation by the discharge conveying system 30.

[0030] This arrangement improves the automation level of seed potato cutting and reduces manual labor intensity; batch cutting greatly improves cutting efficiency; and the plurality of limiting pieces 207 set in gaps are used to enable the blades on the cutting roller 204 to be located between the gaps to completely cut the seed potatoes without damaging the conveying roller.

[0031] Example 2: This embodiment further expands the limiting piece 207 on the basis of the above embodiment. Figure 7 As shown, the limiting piece 207 is in the shape of a cone; two adjacent limiting pieces 207 on the same roller shaft 221 are set in opposite directions; two limiting pieces 207 at the same position on two adjacent roller shafts 221 are set in the same direction; two adjacent limiting pieces 207 on one roller shaft 221 are combined with the other two limiting pieces 207 on the adjacent roller shaft 221 to form a limiting pit for limiting the seed potato.

[0032] When the seed potatoes fall onto the conveyor roller, due to the presence of the limiting pits, each individual seed potato will roll into the limiting pit, so that the center of the seed potato can be located in the gap between the two limiting pieces 207. When the seed potato moves to the blade, the blade can cut it right in the middle of the seed potato, so that the two halves of the seed potato can be almost the same size, thereby improving the uniformity of cutting.

[0033] Furthermore, the transport unit further includes an eighth sprocket 220 and a fixed chain. The eighth sprocket 220 is mounted on the roller shaft 221 . Both ends of the fixed chain are fixed on the frame. The fixed chain is engaged with the eighth sprocket 220 .

[0034] The fixed chain has the same structure as the conveying chain, but is longer and is evenly distributed on the periphery of the conveying chain. It is not shown in the figure. When the conveying chain drives the conveying roller to move, the eighth sprocket 220 engages with the fixed chain, so the eighth sprocket 220 will rotate. At this time, the rotation direction of the eighth sprocket 220 is opposite to the rotation direction of the drive shaft 222; at this time, the seed potato is between the two conveying rollers, and is driven by the conveying rollers. The seed potato begins to roll, and the rolling direction is opposite to that of the conveying rollers; the seed potato begins to adjust its own posture when rolling. For example, the elliptical seed potato will change from an upright state to a lying state, ensuring that the blade will not fall over when cutting the seed potato, causing uneven cutting.

[0035] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0036] Example 3: This embodiment further expands the cutting part on the basis of the above embodiment. Figure 8As shown, the cutting part also includes a disinfection unit, which includes a disinfectant box 208, a nozzle 209, a disinfection pump 210, and a guide tube 211. The disinfectant box 208, the disinfection pump 210, and the guide tube 211 are all installed on the mounting frame. One end of the disinfection pump 210 is connected to the disinfectant box 208, and the other end is connected to the guide tube 211. Multiple nozzles 209 are connected to the guide tube 211, and the nozzles 209 spray the medicine on the cutting roller 204.

[0037] The disinfection pump 210 is started regularly. When started, the disinfection pump 210 pumps the disinfectant in the disinfectant box 208 into the guide pipe 211, and then sprays it onto the blade through the nozzle 209. This setting allows pre-disinfection before each seed potato cutting. If individual seed potatoes are rotten during the cutting process and contaminate the blade, the nozzle 209 can also disinfect them to prevent affecting the cutting of other seed potatoes.

[0038] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0039] Example 4: This embodiment further expands the cutting part on the basis of the above embodiment. Figure 8 、 Figure 9 As shown, the cutting part also includes a sharpening unit, which includes a movable frame, an adjusting frame, and a sharpening piece 226, and the sharpening piece 226 is installed on the adjusting frame; the mounting frame includes a frame body 201 and a protective net 202, a discharge trough 205, and an introduction plate 206 installed on the frame body 201, and the protective net 202 is used to protect the driving part; the discharge trough 205 and the introduction plate 206 are used for unloading guidance and loading guidance respectively; a movable mounting plate 230 is slidably connected to the frame body 201, and the cutting roller 204 is rotatably connected to the movable mounting plate 230, and the movable frame is used to change the position of the movable mounting plate 230.

[0040] Furthermore, the adjustment frame includes a second rotating crank 224 rotatably connected to the frame body 201 , a third rotating crank 225 is slidably connected to the second rotating crank 224 , and the sharpening member 226 is mounted on the third rotating crank 225 .

[0041] Furthermore, the movable frame includes a first rotating crank 223, an adjusting chain and two symmetrically arranged groups of adjusting parts, the adjusting parts include a sleeve 228 and a screw 229, the screw 229 is installed on the frame body 201, the screw 229 is threadedly connected to the sleeve 228, and the sleeve 228 is rotatably connected to the movable mounting plate 230; a ninth sprocket 231 is installed on the screw 229, the adjusting chain is used to synchronously drive two ninth sprockets 231, and the first rotating crank 223 is installed on a screw 229.

[0042] When the knife needs to be sharpened, the first rotating crank 223 is manually rotated. At this time, the first rotating crank 223 drives the connected screw 229, and the screw 229 rotates on the sleeve 228. At the same time, the ninth sprocket 231 on the screw 229 drives another set of adjusting parts through the adjustment chain, that is, the two screws 229 rotate synchronously on the sleeve 228. At this time, the screw 229 drives the movable mounting plate 230, and the movable mounting plate 230 drives the cutting roller 204 to approach the sharpening part 226, so that the blade is stuck in the introduction plate 206. At this time, when the cutting roller 204 rotates, the sharpening part 226 will The corresponding blade is sharpened. After the grinding is completed, the second rotating crank 224 is manually turned, and the sharpening member 226 rotates and disengages from the blade. At the same time, the third rotating crank 225 is manually pulled, so that the sharpening member 226 is synchronously moved horizontally to another blade. At this time, the second rotating crank 224 is turned back to its original position, and the sharpening member 226 starts to sharpen another blade. The above operation is repeated until all blades are sharpened. At this time, the first rotating crank 223 is rotated in the opposite direction, and the cutting roller 204 is reset. At this time, the sharpening member 226 is separated from the blade. In this way, the blade can be quickly sharpened without disassembling it.

[0043] The other parts of this embodiment are the same as those of the above embodiment and will not be described in detail.

[0044] Example 5: This embodiment further expands the cutting part on the basis of the above embodiment. Figure 9 As shown, the cutting part further includes a combing unit, which includes a combing frame 227. The combing frame 227 is installed on the frame 201. The combing frame 227 is provided with a plurality of combing teeth. The blade on the cutting roller 204 is located between two adjacent combing teeth.

[0045] When the blades on the cutting roller 204 cut the seed potatoes into pieces, some of the seed potatoes will stick to the blades, so the combing teeth on the combing frame 227 are used to block them, ensuring that the seed potatoes can be separated from the blades and smoothly transported to the discharge transmission system 30.

[0046] Example 6: This embodiment further expands the driving part based on the above embodiment. Figure 4 、 Figure 5 As shown, the driving part includes a motor 203, a pulley 212, a transmission sprocket group, a drive sprocket group, a cutting sprocket group, a transmission chain, a drive chain, and a cutting chain.

For example, a mounting base for moving the motor 203 is provided at the bottom of the motor 203 to adjust the tension of the belt. A movable pull rod is provided on the frame 201, and a tensioning sprocket is mounted on the pull rod for engaging with the transmission chain, the drive chain, or the cutting chain. A tension spring is provided between the pull rod and the frame 201. Under the action of the tension spring, the pull rod drives the tensioning sprocket to always press the corresponding chain. Because a sprocket is provided to tension the cutting chain, the cutting chain can still drive the cutting roller 204 when the cutting roller 204 moves for grinding.

[0047] When in use, the motor 203 is started, and the motor 203 drives the pulley 212 through the belt, and the pulley 212 drives the coaxial fourth sprocket 216. The fourth sprocket 216 drives the first sprocket 213 through the transmission chain, and the first sprocket 213 drives the coaxial fifth sprocket 217.
