Description

Technical fields:

[0001] This utility model relates to the field of garlic seed budding technology, specifically to garlic seed budding duckbill based on visual recognition technology. Background technology:

[0002] Planting garlic with upright sprouts can improve the germination rate and growth effect of garlic seeds. Currently, most mature upright sprouting equipment on the market adopts a double-duckbill upright sprouting structure to achieve upright sprouting. The double-duckbill structure includes a fixed duckbill (also called a fixed garlic seed cup) and a moving duckbill (also called a moving garlic seed cup). The fixed duckbill is fixed on the frame, and the moving duckbill is set in the planting mechanism. The moving duckbill rotates while maintaining an upright position through its own rotation, and a gap is left at the lower end of the fixed duckbill. The seed picking mechanism guides the garlic seed into the fixed duckbill. The garlic seed has two states in the fixed duckbill: one is sprout facing up, and the other is sprout facing down. When the sprout is facing up (upright sprout), when the moving duckbill rotates to the position of the fixed duckbill, it opens the fixed duckbill, and the garlic seed falls directly into the moving duckbill in an upright sprout position. The garlic clove is placed inside the mouthpiece, and then the bud is planted. When the bud is facing down, it will leak out through the gap at the bottom of the fixed duckbill. When the moving duckbill rotates to the fixed duckbill position, it presses down on the bud and opens the fixed duckbill. At this time, because the bud of the garlic clove is held, the root of the garlic clove falls first, thus achieving the direction of the garlic clove's fall. Finally, the garlic clove falls into the moving duckbill with the bud facing up, thus achieving the correct bud planting. For details, please refer to the Chinese patent disclosure of a garlic planting machine (authorization announcement number: CN106068830B).

[0003] The application of the aforementioned double-duckbill bud-aligning structure has resulted in a garlic bud-aligning rate of 80% to 90%, and corresponding garlic planting equipment has been widely adopted. Further improving the garlic bud-aligning rate, especially to around 95%, has become a primary task. Since the orientation of the double-duckbill bud-aligning structure relies mainly on clamping the garlic bud, many uncontrollable factors arise. For example, if the garlic clove is not fully upright within the fixed duckbill, the bud's position changes, causing the moving duckbill to fail to accurately clamp the bud, leading to orientation failure. Furthermore, variations in garlic clove size, bud length, and bud toughness can result in buds being broken or unable to properly extend through the gap, further hindering orientation. These combined unfavorable factors limit further improvements in the bud-aligning rate of the double-duckbill bud-aligning structure.

[0004] Visual recognition technology is an important field of artificial intelligence. It can recognize and understand the content in images and videos. Currently, visual recognition technology has been widely applied in many fields, and the technology is relatively mature. Researchers have already applied visual recognition technology to garlic planting, specifically identifying the orientation of garlic sprouts and then using appropriate adjustment mechanisms to ensure the sprouts are planted correctly. For example, Chinese patents disclose a garlic sprout orientation adjustment mechanism and device based on visual recognition (publication number: CN116472824A), and another Chinese patent discloses a garlic planting sprout orientation visual detection system and its detection method (publication number: CN112082996A). Based on existing information, it is undoubtedly technically mature and feasible to use visual recognition technology to identify the orientation of garlic seeds. The most important challenge is ensuring that the garlic seeds are planted correctly with the sprouts already planted.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content:

[0006] The purpose of this invention is to solve the problems existing in the prior art and provide a garlic seed bud-aligning duckbill based on visual recognition technology. Based on visual recognition technology, the orientation of the flat garlic seed is first identified. Then, a U-shaped flip plate and cover plate structure is used to achieve fast, accurate and reliable garlic seed orientation adjustment through electric drive, so that the garlic seed falls in the correct bud position, which significantly improves the bud-aligning rate of garlic planting.

[0007] This utility model achieves the above objectives by adopting the following technical solutions:

[0008] A garlic seed bud-aligning duckbill based on visual recognition technology includes a base with a flipping mechanism. The flipping mechanism includes a motor base mounted on the base, a flipping motor horizontally mounted on the motor base, and a rotating shaft connected to the flipping motor via a reducer. A U-shaped flap is mounted at the front end of the rotating shaft, the U-shaped flap being vertically positioned. Baffles are mounted at both ends of the U-shaped flap, and these baffles are mounted on the base with a gap between them. A mounting plate is mounted on the rotating shaft, and an electric cylinder is mounted on the mounting plate. A cover plate is connected to the front end of the electric cylinder to cover the upper part of the U-shaped flap. A fixed duckbill is mounted below the U-shaped flap, vertically positioned on the base. When the U-shaped flap is in a horizontal position, it receives garlic seeds and makes them lie flat vertically. The U-shaped flap rotates according to the orientation of the garlic seeds, causing them to fall into the fixed duckbill with the bud aligned.

[0009] The U-shaped flap includes a base plate, and side plates are provided on both sides of the base plate, one of which is connected to a rotating shaft.

[0010] The side panel includes an integrally formed upright section and a bent section. The upright section is perpendicular to the base plate, and the bent section is bent outward.

[0011] The base is provided with a seated bearing, and the rotating shaft is rotatably mounted on the seated bearing.

[0012] The fixed duckbill includes a duckbill A part and a duckbill B part that are rotatably mounted on the base. The duckbill A part is provided with an arc gear A on its inner side, and the duckbill B part is provided with an arc gear B that meshes with the arc gear A on its inner side. A return spring is provided between the duckbill A part and the duckbill B part. The lower end of the duckbill B part is provided with a protrusion plate that cooperates with the movable duckbill to open the fixed duckbill.

[0013] The present invention, by adopting the above-described structure, can bring the following beneficial effects:

[0014] (1) By designing a U-shaped flip plate, garlic cloves are received; the garlic cloves lie flat in the longitudinal direction for easy identification of the garlic clove orientation by taking pictures; rotating 90° so that the garlic cloves are located above the middle of the fixed duckbill, and the garlic cloves can fall directly to the bottom of the fixed duckbill, maintaining the correct bud posture of the garlic cloves to the greatest extent, and effectively avoiding the garlic cloves changing the correct bud posture or causing a large tilt due to contact with the side wall. (2) Since the flipping action is added, this undoubtedly increases the running time of the original double duckbill correct bud structure. Therefore, the flipping action must be as fast as possible. Therefore, the flipping motor, reducer and shaft drive of the U-shaped flip plate are directly adopted. In order to meet the needs of rapid flipping and avoid the garlic cloves being thrown out of the U-shaped flip plate due to rapid flipping, an electric cylinder and cover plate are designed to temporarily close the upper part of the U-shaped flip plate, thereby achieving the purpose of rapid, accurate and reliable material flipping.

Detailed implementation method:

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0024] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0025] Furthermore, terms such as “upper end” and “lower end” are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the location of the indicated technical feature.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] like Figure 1-6As shown, the garlic seed sprouting duckbill based on visual recognition technology includes a base 1, on which a flipping mechanism 2 is provided. The flipping mechanism 2 includes a motor base 201 mounted on the base 1, and a flipping motor 202 is horizontally mounted on the motor base 201. The flipping motor 202 is connected to a rotating shaft 204 via a reducer 203. A U-shaped flap 205 is provided at the front end of the rotating shaft 204. The U-shaped flap 205 is arranged vertically, and baffles 206 are provided at both ends of the U-shaped flap 205 (since the two ends of the U-shaped flap 205 are open and need to be rotated to deliver the garlic seed, baffles 206 are designed to ensure that the garlic seed remains inside the U-shaped flap 205 to prevent the garlic seed from sliding out from both ends during receiving). The baffles 206 are located on the base 1. On the base 1, a gap is left between the baffle 206 and the U-shaped flip plate 205 (because the U-shaped flip plate 205 also needs to be flipped, so a sufficient gap is needed for rotation). The rotating shaft 204 is provided with a mounting plate 207, and the mounting plate 207 is provided with an electric cylinder 208. The front end of the electric cylinder 208 is connected to a cover plate 209. The cover plate 209 is used to cover the upper end of the U-shaped flip plate 205. A fixed duckbill 3 is provided below the U-shaped flip plate 205. The fixed duckbill 3 is vertically set on the base 1. When the U-shaped flip plate 205 is in a horizontal position, it is used to receive the garlic seed 4 and make the garlic seed 4 lie flat in the longitudinal direction. The U-shaped flip plate 205 selects the rotation direction according to the orientation of the garlic seed 4 so that the garlic seed 4 falls into the fixed duckbill 3 with the bud in the correct position. By designing a U-shaped flip plate 205, the garlic seed 4 is received; the garlic seed 4 lies vertically flat for easy identification of its orientation when photographed; rotating 90° positions the garlic seed 4 above the middle of the fixed duckbill 3, allowing it to fall directly to the bottom of the fixed duckbill 3, maximizing the maintenance of the garlic seed 4's upright bud posture and effectively preventing it from changing its upright bud posture or tilting significantly due to contact with the sidewall. Since the added flipping action undoubtedly increases the operating time of the original double duckbill upright bud structure, the flipping action must be as fast as possible. Therefore, a flipping motor 202, a reducer 203, and a rotating shaft 204 are used to drive the U-shaped flip plate 205. Electrical drive rotation meets the requirement for rapid flipping. To prevent the garlic seed 4 from being thrown out of the U-shaped flip plate 205 due to rapid flipping, an electric cylinder 208 and a cover plate 209 are designed to temporarily close the upper end of the U-shaped flip plate 205, thereby achieving the purpose of fast, accurate, and reliable flipping.

[0028] The U-shaped flap 205 includes a base plate 2051, and side plates 2052 are respectively provided on both sides of the base plate 2051. One of the side plates 2052 is connected to the rotating shaft 204. This design allows for better material receiving, and the spacing between the two side plates 2052 is designed to ensure that the garlic seeds lie flat on the base plate 2051 longitudinally to the greatest extent possible.

[0029] The side panel 2052 includes an integrally formed upright section 2053 and a bent section 2054. The upright section 2053 is perpendicular to the base plate 2051, and the bent section 2054 is bent outward. Enlarging the upper opening facilitates better material reception.

[0030] The base 1 is provided with a seated bearing 210, and the rotating shaft 204 is rotatably mounted on the seated bearing 210. This improves the support strength and rotational stability of the rotating shaft 204.

[0031] The fixed beak 3 includes a beak A part 301 and a beak B part 302 respectively rotatably mounted on the base 1. An arc gear A303 is provided on the inner side of the beak A part 301, and an arc gear B304 meshing with the arc gear A303 is provided on the inner side of the beak B part 302. A return spring 305 is provided between the beak A part 301 and the beak B part 302. A protruding plate 306, which cooperates with the movable beak 5 to open the fixed beak 3, is provided at the lower end of the beak B part 302. The specific structure of the fixed beak 3 is given, so that its upper end can receive garlic cloves 4 falling in a positive bud posture, and its lower end can cooperate with the movable beak 5 to open, allowing the temporarily stored garlic cloves to fall into the movable beak 5 while maintaining a positive bud posture.

[0032] The garlic seed budding method based on visual recognition technology includes the garlic seed budding duckbill as described above. Garlic seed 4 is guided onto the U-shaped flap 205 (the seed-taking mechanism and feed box on an existing garlic planter can be used directly to guide the garlic seed onto the U-shaped flap 205). Under the action of the U-shaped flap 205, the garlic seed 4 is vertically positioned on the U-shaped flap 205. The orientation of the garlic seed is identified by a visual recognition system (existing technology, which can be directly purchased or customized by a third party). (A camera is usually designed above the U-shaped flap 205 to take pictures, and then the images are transmitted to the visual recognition system to identify the orientation of the garlic seed). Then, the electric cylinder 208 is activated to extend the cover plate 209. The cover plate 209 covers the U-shaped flip plate 205. According to the orientation of the garlic seed, the flipping motor 202 drives the U-shaped flip plate 205 to rotate in the opposite direction so that the garlic seed 4 falls into the fixed duckbill 3 with the bud in the correct position. Then the U-shaped flip plate 205 returns to the horizontal state. The moving duckbill 5 (a component in the existing planting mechanism 6, the planting mechanism 6 and the garlic seed budding duckbill of this application are installed on the frame 7 of the garlic planting equipment) opens the fixed duckbill 3 during rotation. The garlic seed 4 in the fixed duckbill 3 continues to fall into the moving duckbill 5 with the bud in the correct position. When the moving duckbill 5 rotates to the planting position, it opens to plant the garlic seed 4 with the bud in the correct position. The cycle is repeated to complete the continuous garlic seed budding planting.

[0033] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0034] Any aspects of this utility model not described in detail are known to those skilled in the art.
