Description

Technical Field

[0001] This invention relates to the field of garlic planting technology, and in particular to a garlic seed bud tip recognition and orientation control system. Background Technology

[0002] To improve the positive germination rate, existing garlic planters typically use a directional device (also called a directional duckbill or directional cup) in conjunction with a planting duckbill to achieve positive germination of garlic seeds. Figure 4 and 5 As shown, its working principle is that the seed-collecting device picks up the seed and guides it into the directional duckbill through the seed guide groove. The directional duckbill has an opening below it for the bud tip to protrude. During rotation, the planting duckbill opens the directional duckbill. If the garlic seed falls into the directional duckbill with the bud tip facing upwards, it will continue to fall into the planting duckbill in that position. If the garlic seed falls into the directional duckbill with the bud tip facing downwards, the bud tip will protrude from the opening. When the planting duckbill opens the directional duckbill, it temporarily squeezes the bud tip. Under the action of gravity, the garlic seed will rotate 180 degrees and fall into the planting duckbill, thus achieving correct bud planting. For details, please refer to a garlic planter previously applied for by our company (authorization announcement number: CN107124923B). Compared with the previous direct planting, the implementation of the above technology significantly improves the correct bud planting rate of garlic (the correct bud planting rate can reach over 80%). However, in practical applications, the correct bud planting rate is still difficult to exceed 90%, which has led to stagnation in the progress of correct bud planting technology. Extensive research indicates that the current technology's difficulty in achieving a 90% success rate is primarily due to the irregularities in garlic clove size, sprout tip size, and clove orientation. In particular, after the garlic clove is placed in the directional planting nozzle, the sprout tip is often not pointing upwards or downwards; instead, it is frequently tilted. Consequently, the length of the sprout tip protruding from the opening is limited, and the planting nozzle cannot effectively compress the sprout tip, thus failing to achieve the desired upright sprout position. Furthermore, in some cases, excessive compression or breakage of the sprout tip occurs during compression, affecting the survival rate and subsequent yield. Summary of the Invention

[0003] This invention provides a garlic seed sprout tip recognition and orientation control system, solving the problems existing in the prior art. By setting a sprout tip recognition and bud-aligning mechanism within the directional nozzle, primary bud alignment is achieved. The directional nozzle, in conjunction with the planting nozzle, achieves secondary bud alignment. This two-stage bud alignment not only helps improve the bud alignment rate, but the use of primary bud alignment also reduces the need for secondary bud alignment, thus minimizing damage to the sprout tips. It has advantages such as a reasonable structural design, primary bud alignment without damaging the sprout tips, and a high bud alignment rate.

[0004] One of the technical solutions adopted in this invention is: A garlic seed sprout identification and orientation control system includes an orientation duckbill, comprising a duckbill A section and a duckbill B section. The duckbill A section is fixedly mounted on a frame, and the duckbill B section is rotatably mounted on the duckbill A section. A U-shaped frame is provided inside the orientation duckbill, and a rotating shaft is connected to the U-shaped frame. The rotating shaft is rotatably mounted on the duckbill A section and connected to a servo motor. An orientation cone is provided on the U-shaped frame, and the orientation cone has an internal conical cavity. The orientation cone is divided into two semi-oriented cones, which are rotatably mounted on the U-shaped frame and meshed with circular arc gears. A return spring A is connected between the two semi-oriented cones. An opening A is provided at the lower end of the orientation cone for the sprout tip to extend. A sensor is provided at the opening A section of the duckbill A section corresponding to the opening A section. The sensor is used to detect whether a sprout tip is extending from the opening A section. A magnet is provided on the lower outer wall of the semi-oriented cone near the duckbill A section, and an electromagnetic chuck is provided on the corresponding duckbill A section. The sensor, servo motor, and electromagnetic chuck are respectively connected to the control system.

[0005] The upper end of the duckbill A section is provided with a surrounding plate, and a seed guide groove is provided above the surrounding plate.

[0006] The lower end of the duckbill B section is extended to provide a squeezing part, and the lower ends of the duckbill A section and the duckbill B section are provided with an opening B for the bud tip to extend out. A return spring B is provided between the duckbill A section and the duckbill B section.

[0007] The machine frame is equipped with a planting device. During the rotation of the planting device, the planting beak opens the directional beak and the garlic cloves inside the directional beak fall into the planting beak with the bud tip facing upward.

[0008] The beneficial effects of this invention are: By fully utilizing the fixed position of part A of the directional duckbill, a directional cone is installed inside the directional duckbill. The structural characteristics of the directional cone effectively reduce the tilting degree of the garlic seed. Based on this, the directional cone is used in conjunction with a sensor to detect the posture of the garlic seed inside the directional cone. Then, a bud-aligning measure is taken according to the posture of the garlic seed. When the garlic seed falls onto the directional cone with the bud tip facing upward, the directional cone can be opened directly by an electromagnetic chuck to let the garlic seed fall into the directional duckbill. When the garlic seed falls onto the directional cone with the bud tip facing downward, a servo motor drives the directional cone to rotate 180 degrees, causing the garlic seed to flip 180 degrees and fall into the directional duckbill with the bud tip facing upward under its own gravity. This technical solution achieves garlic seed orientation without compressing the bud tip. At the same time, in conjunction with the directional duckbill and the planting duckbill, a two-stage bud-aligning effect is formed, significantly improving the bud-aligning rate to about 95%.

[0010] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0011] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0012] like Figure 1-3As shown, a garlic seed sprout identification and orientation control system includes an orientation duckbill 1, which comprises a duckbill A section 2 and a duckbill B section 3. The duckbill A section 2 is fixedly mounted on a frame 4, and the duckbill B section 3 is rotatably mounted on the duckbill A section 2. A U-shaped frame 5 is provided inside the orientation duckbill 1, and a rotating shaft 6 is connected to the U-shaped frame 5. The rotating shaft 6 is rotatably mounted on the duckbill A section 2 and connected to a servo motor 7. The servo motor 7 can be mounted on the duckbill A section 2 or the frame 4. An orientation cone 8 is provided on the U-shaped frame 5. The orientation cone 8 has an internal conical cavity 9 and is designed as two semi-directional cones 10. The semi-directional cone 10 is rotatably mounted on the U-shaped frame 5, and the two semi-directional cones 10 are meshed by a circular arc gear 11. A return spring A12 is connected between the two semi-directional cones 10. The lower end of the directional cone 8 is provided with an opening A13 for the bud tip 25 to extend out. The duckbill A part 2 is provided with a sensor 14 corresponding to the opening A13. The sensor 14 is used to detect whether the bud tip 25 extends out at the opening A13. A magnet 15 is provided on the lower outer wall of the semi-directional cone 10 near the duckbill A part 2. An electromagnetic chuck 16 is provided on the corresponding duckbill A part 2. The sensor 14, the servo motor 7 and the electromagnetic chuck 16 are respectively connected to the control system 26. Compared with existing bud-planting structures, this application fully utilizes the fixed feature of the duckbill A part 2 in the directional duckbill 1. The fixed duckbill A part 2 makes subsequent installation design easier to implement, and the operation of each component is more stable. A directional cone 8 is set inside the directional duckbill 1. The structural features of the directional cone 8 can effectively reduce the tilting degree of the garlic seed 24. Previously, the garlic seed was placed within the duckbill structure, which resulted in a large tilting angle and range for the garlic seed 24, making it difficult to maintain a vertical posture. The design of the cone cavity 9 reduces the tilting angle of the garlic seed 24, making it more inclined to a vertical posture, which is very beneficial for subsequent bud-planting. Based on this, the directional cone 8 is used in conjunction with the sensor 14 to detect the posture of the garlic seed 24 within the directional cone 8, and then... The garlic seed 24 adopts a directional bud-aligning method. When the garlic seed 24 lands on the directional cone 8 with the bud tip 25 facing upwards, the directional cone 8 can be opened directly by the electromagnetic chuck 16 and the magnet 15, allowing the garlic seed 24 to fall into the directional duckbill 1 for planting. When the garlic seed 24 lands on the directional cone 8 with the bud tip 25 facing downwards, the servo motor 7 drives the U-shaped frame 5 and the directional cone 8 to rotate 180 degrees, causing the garlic seed 24 to flip 180 degrees and fall into the directional duckbill 1 with the bud tip 25 facing upwards under its own gravity. This technical solution achieves garlic seed orientation without compressing the bud tip 25. At the same time, it forms a two-stage directional bud alignment with the directional duckbill 1 and the planting duckbill 23, significantly improving the bud alignment rate, which can reach about 95%.

[0013] The upper end of the duckbill A part 2 is provided with a surrounding plate 17, and a seed guide groove 18 is provided above the surrounding plate 17. The design of the surrounding plate 17 can be adjusted in vertical height according to actual conditions, and can also better adapt to the design of the directional cone 8 to prevent the garlic seed 24 from being thrown out or falling.

[0014] The lower end of the duckbill B part 3 is extended with a squeezing part 19. The lower ends of the duckbill A part 2 and the duckbill B part 3 are provided with openings B20 for the bud tip 25 to extend. A return spring B21 is provided between the duckbill A part 2 and the duckbill B part 3. The squeezing part 19 cooperates with the planting duckbill 23 to open the planting duckbill 1 and perform secondary directional bud correction. The structure of this application is based on primary directional bud correction and supplemented by secondary directional bud correction. The two-stage cooperation significantly improves the bud correction rate while reducing damage to the bud tip 25 of the garlic seed 24.

[0015] The frame 4 is provided with a planting device 22. During the rotation of the planting device 22, the planting beak 23 opens the directional beak 2 and the garlic seed 24 inside the directional beak 2 falls into the planting beak 23 with the bud tip 25 facing upward.

[0016] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0017] Any aspects of this invention not described in detail are well-known to those skilled in the art.
