Description

Technical Field

[0001] This utility model relates to the field of potato seed selection technology, specifically to a device for identifying and classifying potato tuber buds and collecting them. Background Technology

[0002] Potato tubers are a type of underground modified stem, consisting of enlarged, irregularly shaped tuberous structures at the ends of underground stems that store nutrients. Potatoes primarily reproduce asexually using tubers because they have buds (or nodes) on them. The number of buds varies, and they are generally arranged in a spiral pattern. Each bud contains 2-3 axillary buds, which can sprout into new branches, thus enabling tuber propagation. However, before asexual propagation, potatoes with buds need to be selected from a large quantity. Currently, manual selection is generally used. However, due to the large quantity of potatoes, the selection efficiency is low, and manual selection over a long period is prone to errors, resulting in a low accuracy rate. Utility Model Content

[0003] This invention addresses the problem that before asexual propagation of potatoes, it is necessary to screen potatoes with buds from a large number of potatoes. Currently, manual selection is generally used, but due to the large number of potatoes, the selection efficiency is low, and manual selection is prone to errors over a long period of time, resulting in low selection accuracy.

A defective collection basket 13 is provided at the bottom of one side of a set of light bars 4. The defective collection basket 13 is set in accordance with the axis of the first push rod electric cylinder 12. A support plate 15 is provided at the other end of the middle of the side of the identification box 7. A second push rod electric cylinder 14 is provided on the upper surface of the support plate 15. A qualified collection basket 10 is provided at the bottom of the other side of a set of light bars 4. The qualified collection basket 10 is set in accordance with the axis of the second push rod electric cylinder 14. An identification camera 18 is provided at the center of the top surface inside the identification box 7. A push rod motor 1 is provided on the other side of the collection trough 2. The output end of the push rod motor 1 passes through the shell of the collection trough 2 and is detachably connected to the middle of the flexible push plate 3.

[0006] Furthermore, the potato rotation drive assembly 6 includes a cylinder 6-1, a fixed plate 6-2, and a rotary slide 6-3; the bottom of the cylinder 6-1 is fixedly connected to the inner bottom surface of the identification box 7, the output end of the cylinder 6-1 is fixedly connected to the center of the bottom surface of the fixed plate 6-2, and the rotary slide 6-3 is fixed on the upper surface of the fixed plate 6-2.

[0007] Furthermore, the rotary slide 6-3 has two sets of fixed pulleys on its rotary platform, and one of the fixed pulleys is driven by a motor.

[0008] Furthermore, a supplementary light 8 is provided at the top of each of the two side walls inside the identification box 7, and a central controller is provided at one end of the bottom surface inside the identification box 7.

[0009] Furthermore, a support leg 17 is provided at each of the four corners of the bottom surface of the identification box 7;

[0010] Furthermore, arc-shaped push plates are respectively provided on the output ends of the first push rod electric cylinder 12 and the second push rod electric cylinder 14;

[0011] Furthermore, a photoelectric limit switch is provided at the center of the upper surface of the rotary platform of the rotary slide 6-3;

[0012] Furthermore, the photoelectric signal output terminal of the photoelectric limit switch is connected to the photoelectric signal input terminal of the central controller, the first drive signal output terminal of the central controller is connected to the first conveyor belt 5, the second drive signal output terminal of the central controller is connected to the cylinder 6-1, the recognition signal output terminal of the recognition camera 18 is connected to the recognition signal input terminal of the central controller, the first pneumatic signal output terminal of the central controller is connected to the first push rod electric cylinder 12, and the second pneumatic signal output terminal of the central controller is connected to the second push rod electric cylinder 14.

[0013] Furthermore, the bottom surface of the collection trough 2 is sloped.

[0014] Furthermore, a light shield is provided around each of the surrounding areas of the supplementary light 8;

[0015] Furthermore, during use, the pre-selected potatoes are placed into the collection trough 2 in batches. Utilizing the slope of the bottom surface of the collection trough 2, the potatoes roll one by one through the discharge port into the space between the two optical bars 4. A first conveyor belt 5 is installed on each side of the optical bars 4. The two first conveyor belts 5 rotate synchronously, causing the potatoes to roll along the optical bars 4 and move into the identification box 7. When a potato moves directly above the potato-driving rotating assembly 6, it will block the photoelectric limiter at the center of the upper surface of the rotating platform 6-3. The infrared light source of the switch prevents the receiver from receiving infrared light, thus transmitting the photoelectric signal of the photoelectric limit switch to the central controller. The central controller then transmits a braking signal to conveyor belt 5, causing it to brake and accurately position the potato directly above the potato rotating assembly 6. At this point, the central controller drives cylinder 6-1, which in turn raises the rotary slide 6-3. The central controller can control the extension and retraction of cylinder 6-1, ensuring that the two sets of fixed pulleys on the rotary slide 6-3 contact the outer surface of the potato, thereby allowing the potato to move. The rotating slide 6-3 drives the potato to rotate axially, and then, through one of the fixed pulleys, a motor drives the potato to rotate circumferentially. During these two rotations, the recognition camera 18 uses an existing recognition algorithm to identify whether there are buds on the potato's outer surface. The recognition camera 18 transmits the identified signal to the central controller, which then controls the first conveyor belt 5 to rotate, moving another potato directly above the potato-driving rotating assembly 6. This potato then contacts the second conveyor belt 9, thus transporting the potato on a set of light bars 4. When the identification camera 18 detects that the potato has an eye, the potato moves to the corresponding position of the second pusher cylinder 14. The second pusher cylinder 14 then extends the arc-shaped pusher plate, pushing the potato into the qualified collection basket 10. When the identification camera 18 detects that the potato does not have an eye, the potato moves to the corresponding position of the first pusher cylinder 12. The first pusher cylinder 12 then extends the arc-shaped pusher plate, pushing the potato into the unqualified collection basket 13. By continuously repeating the above steps, the potatoes with identification capabilities will be classified and identified, and then collected separately.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] This invention overcomes the shortcomings of existing technologies. Utilizing this structure, the potato tuber bud identification device only requires manual placement of potatoes one by one into the collection trough. Two conveyor belts then transport the potatoes one by one to the top of the potato rotation drive assembly inside the identification box. The drive assembly rotates the potatoes in both axial and lateral directions. A recognition camera, using existing algorithms, identifies the presence of buds on the potato's outer surface. The camera transmits the identified signal to the central controller, which then controls the rotation of the first conveyor belt to move the potato to the second conveyor belt. The system uses contact to move potatoes along a set of light bars. When the recognition camera detects that a potato has an eye, the potato moves to the corresponding position of the second pusher cylinder, which extends the arc-shaped pusher plate and pushes the potato into the qualified collection basket. When the recognition camera detects that a potato does not have an eye, the potato moves to the corresponding position of the first pusher cylinder, which extends the arc-shaped pusher plate and pushes the potato into the unqualified collection basket. By continuously repeating the above steps, the potatoes with the recognition system are identified, classified, and collected, thereby improving the efficiency of identifying potato eye and the accuracy of selection.

An identification box 7 is provided on one side of the collecting trough 2. A square through hole is machined in the middle of the two sides of the identification box 7. The ends of the two light bars 4 pass through the identification box 7 and are fixedly connected to the crossbeam of the fixing frame 16. A first conveyor belt 5 is provided on both sides of a set of light bars 4, and one end of each first conveyor belt 5 is fixedly connected to the side of the collecting trough 2 by a bracket. After passing through the square through hole on one side of the identification box 7, each first conveyor belt 5 is connected to the inner wall of the identification box 7 by a bracket. A potato rotation drive assembly 6 is provided in the center of the bottom surface inside the identification box 7. A second conveyor belt 9 is provided between the two light bars 4. The second conveyor belt 9 is fixed to the ground by a frame, and one end of the second conveyor belt 9 is fixed to the ground by a bracket. The end contacts the side of the potato rotating assembly 6. An L-shaped support plate 11 is provided at one end of the middle of the side of the identification box 7. A first push rod electric cylinder 12 is provided on the vertical section of the L-shaped support plate 11. A defective collection basket 13 is provided at the bottom of one side of a set of light bars 4. The defective collection basket 13 is set in accordance with the axis of the first push rod electric cylinder 12. A support plate 15 is provided at the other end of the middle of the side of the identification box 7. A second push rod electric cylinder 14 is provided on the upper surface of the support plate 15. A qualified collection basket 10 is provided at the bottom of the other side of a set of light bars 4. The qualified collection basket 10 is set in accordance with the axis of the second push rod electric cylinder 14. An identification camera 18 is provided at the center of the top surface inside the identification box 7. A push rod motor 1 is provided on the other side of the collection trough 2. The output end of the push rod motor 1 passes through the shell of the collection trough 2 and is detachably connected to the middle of the flexible push plate 3.

[0022] In this specific embodiment, during use, pre-selected potatoes are placed into the collection trough 2 in batches. Utilizing the slope of the bottom surface of the collection trough 2, the potatoes roll one by one through the discharge port into the space between the two optical bars 4. A primary conveyor belt 5 is located on each side of the optical bars 4. The two primary conveyor belts 5 rotate synchronously, causing the potatoes to roll along the optical bars 4 and move into the identification box 7. When a potato moves directly above the potato rotation drive assembly 6, it blocks the photoelectric sensor at the center of the upper surface of the rotating platform of the rotary slide 6-3. The infrared light source of the limit switch prevents the receiver from receiving infrared light, thus transmitting the photoelectric signal from the photoelectric limit switch to the central controller. The central controller then transmits a braking signal to conveyor belt 5, causing it to brake and accurately position the potato directly above the potato rotating assembly 6. At this point, the central controller drives cylinder 6-1, which in turn raises the rotary slide 6-3. The central controller can control the extension and retraction of cylinder 6-1, ensuring that the two sets of fixed pulleys on the rotary slide 6-3 contact the outer surface of the potato, thereby... The potato is axially rotated by a rotary slide 6-3, and then rotated circumferentially by a motor driven by one of the fixed pulleys. During these two rotations, the recognition camera 18 uses an existing recognition algorithm to identify whether there are buds on the potato's outer surface. The recognition camera 18 transmits the identified signal to the central controller, which then controls the first conveyor belt 5 to rotate, moving another potato directly above the potato-rotating assembly 6. This potato then contacts the second conveyor belt 9, thus placing the potato on a set of light bars 4. During the process, when the identification camera 18 detects that the potato has an eye, the potato moves to the corresponding position of the second pusher cylinder 14. The second pusher cylinder 14 then extends the arc-shaped pusher plate, pushing the potato into the qualified collection basket 10. When the identification camera 18 detects that the potato does not have an eye, the potato moves to the corresponding position of the first pusher cylinder 12. The first pusher cylinder 12 then extends the arc-shaped pusher plate, pushing the potato into the unqualified collection basket 13. By continuously repeating the above steps, the potatoes with identification capabilities will be classified and identified, and then collected separately.

[0036] Working principle

[0037] In use, the pre-selected potatoes are placed into the collection trough 2 one by one. Utilizing the slope of the bottom surface of the collection trough 2, the potatoes will roll one by one through the discharge port into the space between the two optical bars 4. A first conveyor belt 5 is located on each side of the optical bars 4. The two first conveyor belts 5 rotate synchronously, causing the potatoes to roll along the optical bars 4 and move into the identification box 7. When a potato moves directly above the potato rotation drive assembly 6, it will block the red light from the photoelectric limit switch at the center of the upper surface of the rotary slide 6-3. An external light source is used to prevent the receiver from receiving infrared light, thus transmitting the photoelectric signal from the photoelectric limit switch to the central controller. The central controller then transmits a braking signal to conveyor belt 5, causing it to brake and accurately position the potato directly above the potato-rotating assembly 6. At this point, the central controller drives cylinder 6-1, which in turn raises the rotary slide 6-3. The central controller can control the extension and retraction of cylinder 6-1, ensuring that the two sets of fixed pulleys on the rotary slide 6-3 contact the outer surface of the potato, allowing it to rotate smoothly. The rotating slide 6-3 drives the potato to rotate axially, and then through one of the fixed pulleys, a motor drives the potato to rotate circumferentially. While the potato is rotating, the recognition camera 18 uses an existing recognition algorithm to identify whether there are buds on the potato's outer surface. The recognition camera 18 transmits the identified signal to the central controller, which then controls the first conveyor belt 5 to rotate, moving another potato directly above the potato-driving rotating assembly 6. This potato then contacts the second conveyor belt 9, thus moving the potato along a set of light bars 4. When the identification camera 18 detects that the potato has an eye, the potato moves to the corresponding position of the second pusher cylinder 14, which then extends the arc-shaped push plate to push the potato into the qualified collection basket 10. When the identification camera 18 detects that the potato does not have an eye, the potato moves to the corresponding position of the first pusher cylinder 12, which then extends the arc-shaped push plate to push the potato into the unqualified collection basket 13. By continuously repeating the above steps, the potatoes with identification capabilities will be classified and identified, and then collected separately.
