Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and in particular relates to an automatic ridge-changing vegetable planter. Background Technology

[0002] Modern advanced seeders, especially precision seeders, connect to a drive wheel at one end, consisting of a chain and gears, and to a precision seed dispenser at the other end, consisting of a shaft, bearings, and a perforated disc. The seed movement within the seeder is as follows: the seed falls into the disc-shaped component, rotates with it, and fills the metering holes. Then, it is pressed into the lower pipe by a spring-loaded seed pressing component. The seed movement within the seeder can be categorized into three types: free fall, rotational motion, and spring-loaded motion. The time of this spring-loaded motion is known as the short-plank time, which is a major cause of seed breakage. This structure not only causes 15% of seeds to break but also affects the sowing speed. In factory production, it is difficult to produce standardized parts, and different spring-loaded seed pressing components, chains of different lengths, and perforated discs are required when sowing different materials, thus affecting the production scale and quantity of seeders.

[0003] As mentioned above, disc seeders are the most commonly used seeders. However, in actual use, firstly, they can only rotate in one direction. When changing rows for seeding, the entire machine needs to be turned around, and space needs to be left at the end of the ridge to facilitate the machine's turning / turning around, reducing the available planting space and income. Secondly, when changing ridges, the entire machine needs to be moved to another ridge, which is inconvenient. Furthermore, currently available automated seeding equipment cannot be operated unattended, resulting in high labor costs. Summary of the Invention

This planter can achieve automated control, automatically change ridges, and sow in both forward and reverse directions, making full use of planting space, with high planting efficiency and low labor costs.

[0041] To further understand the invention's content, features, and effects, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0042] Please also refer to Figures 1 to 9 The automatic ridge-changing vegetable planter of the present invention will now be described in detail with reference to the accompanying drawings.

[0043] like Figure 1 As shown, the automatic ridge-changing vegetable planter includes: an extension mechanism 1, comprising a first support 101, a first slide rail 102 screwed to the top of the first support 101, a movable plate 103 slidably connected inside the first slide rail 102, and two movable plates 103 symmetrically arranged around the center of the first support 101; a lifting mechanism 2, comprising a ball screw 201 screwed to the bottom of the movable plate 103; a translation drive mechanism 3, a second slide rail 301 screwed to the bottom of the first support 101, the translation drive mechanism 3 slidably connected along the second slide rail 301; and a seeding wheel 4 rotatably connected to the first support 101. The translation drive mechanism 3 is internal; the movement drive mechanism 5 includes an electric drive wheel 501 and a rotating wheel 502 fixed to the bottom of the translation drive mechanism 3 with screws. There are two electric drive wheels 501 and two rotating wheels 502. The electric drive wheels 501 and the rotating wheels 502 are located at the two ends of the second bracket 303 respectively; the control mechanism 6 includes an integrated circuit board 601 installed with screws at the bottom of the first bracket 101. The integrated circuit board 601 is electrically connected to a power supply 602. A control unit is integrated on the integrated circuit. The control unit is electrically connected to the extension mechanism 1, the lifting mechanism 2 and the movement drive mechanism 5.

[0044] Among them, such as Figure 2 As shown, the extension mechanism 1 is used to control the relative position of the two moving plates 103. Specifically, the end of the moving plate 103 away from the first slide rail 102 is fixed with a rack 104, and a gear 105 meshes between the two racks 104. A drive shaft 106 is fixed inside the gear 105. The drive shaft 106 is rotatably connected inside the first bracket 101, and the end of the drive shaft 106 away from the gear 105 is connected to a first servo motor 107.

[0045] Then, when the first servo motor 107 rotates forward, the gear 105 is driven to rotate clockwise by the drive shaft 106. At this time, the two racks 104 move towards the outside of the first bracket 101 when they are meshed, thereby changing the spacing of the lifting mechanism 2.

[0046] Further as Figure 2As shown, the lifting mechanism 2 is adjusted by rotating the ball screw 201. In this embodiment, the end of the ball screw 201 away from the moving plate 103 is connected to a geared motor 202. The bottom screw of the geared motor 202 is screwed to install a screw bracket 203. When the geared motor 202 is working, it drives the ball screw 201 to rotate. By changing the driving rotation direction of the geared motor 202, the screw bracket 203 can move up and down. The driving principle of the ball screw 201 is based on existing conventional technology.

[0047] Among them, such as Figure 4 As shown, the translation drive mechanism 3 includes a sliding block 302 slidably connected to the bottom of the second slide rail 301. A second bracket 303 is screwed to the end of the sliding block 302 away from the second slide rail 301. A lead screw 304 is rotatably connected inside the second slide rail 301. A second servo motor 305 is connected to one end of the lead screw 304. The second servo motor 305 is fixed to one end of the second slide rail 301. The lead screw 304 and the sliding block 302 are threadedly connected. Specifically, after the second servo motor 305 is turned on, as the second servo motor 305 switches between forward and reverse directions, it can drive the lead screw 304 to rotate clockwise or counterclockwise. As a result, the sliding block 302, which is threadedly connected to the lead screw 304, can slide left and right along the second slide rail 301.

[0048] like Figure 7 As shown, a disc motor 7 is fixed on one side of the seeding wheel 4, and a connecting rod 8 is rotatably connected to the other side. The end of the connecting rod 8 away from the seeding wheel 4 is fixed to the bottom of the sliding block 302.

[0049] In this embodiment, the seeding wheel 4 can achieve forward and reverse sowing. Several discharge nozzles 9 are fixed on the side wall of the seeding wheel 4. The discharge nozzles 9 are set at equal angles along the circumference of the seeding wheel 4. Each discharge nozzle 9 is covered with a cover plate 10 that is rotatably connected inside the discharge nozzle 9. The cover plate 10 is connected to a cover plate opening and closing component on the side away from the discharge nozzle 9.

[0050] The cover plate opening and closing mechanism includes a rotating shaft 11 rotatably connected to the side of the seeding wheel 4. A first drive arm 12 is rotatably connected to the outside of the rotating shaft 11. A second drive arm 13 is sleeved inside the first drive arm 12. The end of the second drive arm 13 near the first drive arm 12 is concentrically rotatably connected to the outside of the rotating shaft 11. A first torsion spring 14 is sleeved outside the rotating shaft 11. Both ends of the first torsion spring 14 are fixed to the inner wall of the second drive arm 13. A stop block 15 is screwed to the side of the connecting rod 8. The stop block 15 interacts with several second drive arms 13 during the rotation of the seeding wheel 4. The drive arm 13 abuts against the side in sequence, and also includes a traction component disposed between the first drive arm 12 and the cover plate 10. Specifically, the traction component includes a traction rod 16 rotatably connected to the cover plate 10. A ring block 17 is fixed to the end of the traction rod 16 away from the cover plate 10. A pull wire 18 is pulled between the ring block 17 and the first drive arm 12. The end of the pull wire 18 away from the ring block 17 is inserted into the inside of the first drive arm 12. A second torsion spring 19 is sleeved on the outside of the traction rod 16. One end of the second torsion spring 19 is fixed to the cover plate 10, and the other end is fixed to the end of the traction rod 16 near the first drive arm 12.

[0051] like Figures 8-9 As shown, the seeding wheel 4 is driven by a disc motor 7. During sowing, the seeding wheel 4 first rotates clockwise. During this rotation, the contact block 15 on the side of the connecting rod 8 contacts the traction rod 16. After contacting the traction rod 16, the traction rod 16 rotates along the rotation point of its cover plate 10. After the traction rod 16 rotates, due to the traction of the first torsion spring 14, the cover plate 10 can be driven to rotate in the opposite direction to the traction rod 16, thereby opening the discharge nozzle 9. The seeds inside the seeding wheel 4 slide down along the discharge nozzle 9. As the seeding wheel 4 continues to rotate, after the traction rod 16 rotates past the contact block 15, under the rebound effect of the first torsion spring 14, the cover plate 10 closes again. At the discharge nozzle 9, when the next traction rod 16 passes the abutment block 15, the next discharge nozzle 9 begins to slide seeds, thereby achieving automatic interval sowing; for the counterclockwise rotation of the sowing wheel 4, during the rotation process, the second drive arm 13 first abuts against the abutment block 15. After the second drive arm 13 is abutted, it begins to rotate along the connection with the rotating shaft 11. At the same time, the second torsion spring 19 is compressed and rotated. The second drive arm 13 abuts against the first drive arm 12, and then the first drive arm 12 begins to rotate toward the middle of the sowing wheel 4. Then, by pulling the pull line 18, the same rotation method of the traction rod 16 can be achieved, thereby achieving the effect of controlling the opening of the cover plate 10.

[0052] In this embodiment, the pull wire 18 used is iron wire.

[0053] like Figure 3As shown, the overall movement of the seeder is achieved through an electric drive wheel 501 and a rotating wheel 502. The electric drive wheel 501 is the driving wheel, and the rotating wheel 502 is the driven wheel. Mounting blocks 503 are provided on both sides of the rotating wheel 502, and the rotating wheel 502 is rotatably connected between two mounting blocks 503. Each mounting block 503 has a sliding mounting rod 504 at the end away from the rotating wheel 502. A washer 505 is fixed to the end of the mounting rod 504 away from the mounting block 503, and a screw is fixed to the end of the mounting rod 504 near the washer 505. On the bracket 303, a spring 506 is sleeved on the outside of the mounting rod 504. One end of the spring 506 is fixed to the pad 505, and the other end is fixed to the mounting block 503. Using the above-mentioned spring 506 structure, when sowing, due to the unevenness of the field ground, the higher part will abut against the rotating wheel 502. At this time, the mounting block 503 slides towards the end of the mounting rod 504, and the spring 506 is compressed. Thus, the mounting block 503, the mounting rod 504 and the spring 506 form a damping mechanism to achieve the overall shock absorption effect of the seeder.

[0054] In this embodiment, the power supply 602 is screwed to the bottom of the first bracket 101, and the control unit includes a microcontroller 603, a Hall controller 604, a relay 605 and an infrared sensor module 606 electrically connected to the integrated circuit board 601.

[0055] Among them, such as Figure 5 As shown, the power supply 602 uses a recyclable lithium battery pack. The integrated circuit board 601 is powered by the power supply 602. At the same time, the first servo motor 107, the second servo motor 305, the disc motor 7, the geared motor 202, and the electric drive wheel 501 are all electrically connected to the integrated circuit board 601. The Hall controller 604 is used to control the rotation speed of the first servo motor 107, the second servo motor 305, and the disc motor 7 to control the moving speed or rotation speed of the lifting and translating or the seeding wheel 4. The infrared sensor is connected in series with the microcontroller 603 and the relay 605. The infrared sensor is used to monitor the position of the ridge. When it approaches the ridge, the value is lower than the threshold of the infrared sensor, which then generates an electrical signal. The microcontroller 603 controls the opening and closing of the relay 605, thereby controlling the opening and closing of the electric drive wheel 501.

[0056] In practical use, the electric drive wheel 501 serves as the active component for driving the overall seeder. During travel, the seeding wheel 4 rotates to begin sowing. As the seeder approaches the field ridge, based on the infrared sensor and the control of the microcontroller 603 and relay 605, the first servo motor 107 drives the opening of the moving plate 103, thereby extending the two lifting mechanisms 2. This allows one of the lead screw supports 203 to move to the other side of the field ridge, simultaneously controlling the lifting mechanism 2 to begin... In operation, the lead screw support 203 is driven by the ball screw 201 to abut against the ground of the field, and then the second support 303 rises relative to the lead screw support 203, suspending the rotating wheel 502 and the electric drive wheel 501 in the air. Then, the second servo motor 305 drives the second support 303 to move towards one side of the ridge. After moving to the other side, the reduction motor 202 controls the ball screw 201 to lift the lead screw support 203, and the rotating wheel 502 or the electric drive wheel 501 touches the ground again, completing the ridge replacement.

[0057] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
