Description

Technical field:

[0001] The invention relates to the technical field of garlic sprout sowing, and in particular to a garlic sprout duckbill based on visual recognition technology and a sprout sowing method. Background technology:

[0002] Garlic positive bud sowing can improve the germination rate and growth effect of garlic seeds. At present, most of the more mature positive bud sowing equipment on the market adopts a double duckbill positive bud structure to achieve positive bud sowing. The double duckbill structure includes a fixed duckbill (also called a fixed garlic seed cup) and a movable duckbill (also called a movable garlic seed cup). The fixed duckbill is fixed on the frame, and the movable duckbill is set in the lower planting mechanism. The movable duckbill rotates while keeping upright by self-rotation, and a gap is left at the lower end of the fixed duckbill; the seed-taking mechanism guides the garlic seeds into the fixed duckbill, and the garlic seeds have two states in the fixed duckbill, one is the bud facing up, and the other is the bud facing down; when the bud is facing up (positive bud), the movable duckbill rotates to the fixed duckbill position and opens the fixed duckbill, and the garlic seeds fall directly into the movable duckbill in the posture of a positive bud. The movable duckbill is in the mouth, and then the bud is planted correctly; when the bud is facing downward, the bud will leak out through the gap left at the lower end of the fixed duckbill. When the movable duckbill rotates to the fixed duckbill position, the movable duckbill presses the bud to open the fixed duckbill. At this time, since the bud of the garlic seed is clamped, the root of the garlic seed falls first, thereby realizing the falling direction of the garlic seed, and finally falls into the movable duckbill with the bud facing upward, thereby realizing the correct bud sowing. For specific contents, please refer to a garlic planting machine disclosed in a Chinese patent (authorization announcement number: CN106068830B).

[0003] The application of the above-mentioned double duckbill bud structure has made the garlic sowing bud rate reach 80% to 90%, and the corresponding garlic sowing equipment has also been promoted and applied. In order to further improve the garlic sowing bud rate, especially how to increase the garlic bud rate to about 95% has become the main task at this stage. Since the reversing of the double duckbill bud structure mainly relies on clamping the garlic bud, this leads to many uncontrollable factors. For example, if the garlic posture is not completely upright in the fixed duckbill, the position of the garlic bud will change, resulting in the inability of the moving duckbill to accurately clamp the garlic bud, resulting in reversal failure; for example, the size of the garlic seeds, the length of the garlic buds, and the toughness of the garlic buds are all different, the garlic buds will be clamped off, the garlic buds cannot stretch out of the gap normally, etc., which will lead to reversal failure. It is the existence of these comprehensive unfavorable factors that limit the further improvement of the bud rate of the double duckbill bud structure.

[0004] Visual recognition technology is an important field of artificial intelligence. It can recognize and understand the content in images and videos. At present, visual recognition technology has been promoted and applied in many fields, and the technology is relatively mature. At present, relevant researchers have applied visual recognition technology to garlic sowing, that is, to identify the direction of garlic sprouts through visual recognition technology, and then to achieve the correct bud design of garlic through the corresponding adjustment mechanism. For example, a Chinese patent discloses a garlic seed correct bud adjustment mechanism and device based on visual recognition (publication number: CN116472824A), and another Chinese patent discloses a garlic sowing correct bud visual detection system and detection method (publication number: CN112082996A). Based on the existing information from many aspects, it can be seen that it is mature and feasible to identify the direction of garlic seeds using visual recognition technology from a technical perspective. There is no doubt about this. Then the most important thing is how to plant garlic seeds smoothly in the correct bud mode under the premise of the garlic seeds’ direction.

The specific structure of the fixed duckbill 3 is given, so that the upper end thereof can receive the garlic seeds 4 falling in the posture of the right bud, and the lower end thereof can cooperate with the moving duckbill 5 to open, and the temporarily stored garlic seeds can be kept in the posture of the right bud and fall into the moving duckbill 5.

[0033] The garlic seed sprouting method based on visual recognition technology includes the garlic seed sprouting duckbill as described above, the garlic seeds 4 are introduced into the U-shaped flap 205 (the seed taking mechanism and the guide box on the existing garlic sowing machine can be directly used to introduce the garlic seeds into the U-shaped flap 205), the garlic seeds 4 are longitudinally arranged on the U-shaped flap 205 under the action of the U-shaped flap 205, and the direction of the garlic seeds is identified by the visual recognition system (existing technology, directly purchased or commissioned to a third party for customization) (usually a camera is designed above the U-shaped flap 205 to take pictures, and then the image is transmitted to the visual recognition system to identify the direction of the garlic seeds), and the electric cylinder 208 is started to extend the cover plate 209 The cover plate 209 covers the U-shaped flap 205. According to the orientation of the garlic seeds, the U-shaped flap 205 is driven by the flip motor 202 to rotate in the opposite direction so that the garlic seeds 4 fall into the fixed duckbill 3 in the correct bud posture. Then the U-shaped flap 205 is reset to a horizontal state, and the movable duckbill 5 (a component in the existing lower planting mechanism 6, the lower planting mechanism 6 and the garlic seed correct bud duckbill of the present application are installed on the frame 7 of the garlic sowing equipment) opens the fixed duckbill 3 during the rotation, and the garlic seeds 4 in the fixed duckbill 3 continue to fall into the movable duckbill 5 in the correct bud posture. When the movable duckbill 5 rotates to the lower planting position, it opens to sow the garlic seeds 4 in the correct bud manner, and the continuous sowing of garlic seeds in the correct bud manner can be completed by repeating this cycle.
