Description

Technical Field

[0001] This application relates to the field of agricultural machinery technology, and in particular to an agricultural no-till strip seeder. Background Technology

[0002] A no-till strip seeder is an agricultural machine that sows seeds on uncultivated stubble land. Also known as a direct seeder, it can complete multiple processes such as ditching, fertilizing, sowing, covering and compacting in one go under straw mulch. It is usually powered by a tractor.

[0003] During the movement of the row seeder along with the tractor, the seed storage box is connected to the disc furrow opener via a discharge pipe. As the row seeder moves, the V-shaped furrow opener rotates and opens furrows under the friction between itself and the soil. The seeds then fall into the furrows through the discharge pipe and are covered with soil by the covering wheel. During the furrowing and sowing process, because the soil has not been deeply tilled, straw on the soil surface or residual roots in the soil have not been removed. This may result in the furrow opener being unable to cut and remove the straw during the furrowing and sowing process. The front end of the furrow opener may be stuck by straw or the accumulation of straw may prevent the furrow opener from rotating normally. The presence of straw reduces the furrowing pressure on the soil, causing the furrow opener to fail to reach the standard furrowing range, and the seed planting depth may not meet the requirements, resulting in missing seedlings, broken rows, or seed burn. If the driver in the tractor cab does not notice this in time and clean the furrow opener, the seed planting depth will continue to be substandard during the sowing process, affecting the crop's absorption of nutrients during growth and leading to a decrease in crop yield. Summary of the Invention

[0004] This application proposes an agricultural no-till row seeder, which features the ability to facilitate workers in locating shallow sowing points and performing reseeding to improve the sowing qualification rate. It also includes real-time monitoring of the ratchet's rotation speed to allow the operator to promptly clean and maintain the furrow opener when straw entanglement or failure to cut straw leads to straw accumulation and affects the sowing depth. This prevents the furrow opener from failing to reach the required depth for extended periods, resulting in widespread unqualified sowing depths, reducing the probability of missing seedlings, broken rows, or seed burn, and ensuring sowing quality. This invention addresses the problem of reduced sowing quality and impacted crop production caused by real-time monitoring of sowing conditions, such as the inability to prevent straw entanglement during furrow opening.

[0005] To achieve the above objectives, this application adopts the following technical solution: an agricultural no-till row seeder, comprising a row seeder body, a plurality of furrow openers slidably mounted on the bottom of the row seeder body, and a support rod fixedly mounted on the row seeder body. A plurality of mounting boxes are fixedly mounted on the support rod, and the mounting boxes are slidably connected to the furrow openers. A storage box is fixedly mounted on the side of the support rod furrow away from the furrow openers, and the storage box is filled with powder. A discharge box is fixedly connected to the bottom of the storage box, and a mounting ring is fixedly mounted on one side of the discharge box. An adjusting mechanism for controlling the discharge of powder from the discharge box is provided inside the mounting ring. The structure includes multiple main adjusting rods rotatably mounted at the bottom of the support rod, each main adjusting rod being adapted to a corresponding storage box. The two ends of each main adjusting rod are respectively connected to the trencher and the adjusting mechanism. A Hall gear sensor is fixedly installed on the inner wall of the mounting ring to detect the speed at which the adjusting mechanism adjusts the discharge speed of the powder inside the discharge box. When the trencher moves upward due to a sudden change in soil conditions during operation, the main adjusting rod drives the adjusting mechanism to control the discharge of powder inside the discharge box to mark the location. At the same time, the Hall gear sensor transmits the signal to the control system and provides a prompt to the driver.

[0006] Furthermore, the adjustment mechanism includes a rotating shaft rotatably installed inside the mounting ring. A ratchet is fixedly installed at the end of the rotating shaft away from the discharge box. A mounting post is fixedly installed on the inner side wall of the mounting ring, and the mounting post is positioned on the side of the ratchet near the support rod. A main tension spring is fixedly installed at the end of the mounting post away from the inner side wall of the mounting ring. A main pawl that meshes with the ratchet is fixedly installed at the end of the main tension spring away from the mounting post. The main adjustment rod is rotatably connected to the main pawl, and the ratchet is moved by the main pawl to drive the rotating shaft to rotate.

[0007] Furthermore, a feeding tray is rotatably installed inside the discharge box, and the bottom of the feeding tray is connected to the storage box. The end of the rotating shaft away from the ratchet passes through the side wall of the discharge box and the mounting ring and is fixedly connected to the feeding tray. Multiple material picking slots are opened on the outer side of the feeding tray. A feeding pipe connected to the discharge box is fixedly installed at the bottom of the discharge box. Two diversion pipes are fixedly connected to the bottom of the feeding pipe. When the rotating shaft rotates, it drives the feeding tray to rotate so that the material picking slot containing powder rotates to the connection of the feeding pipe of the discharge box.

[0008] Furthermore, a support shaft is fixedly installed on the top of the trencher, and a limiting slide rod is fixedly installed on the top of the support shaft. The limiting slide rod is slidably connected to the mounting box for limiting. A buffer spring is fitted on the outside of the support shaft, and the two ends of the buffer spring are fixedly connected to the top of the trencher and the bottom of the mounting box, respectively, for buffering the trencher.

[0009] Furthermore, a secondary adjusting rod is rotatably mounted on the end of the main adjusting rod away from the mounting ring, and the end of the secondary adjusting rod away from the main adjusting rod is fitted onto the outside of the limiting slide rod and rotatably connected to it.

[0010] Furthermore, multiple support plates are fixedly installed at the bottom of the support rod, and a hinge shaft is fixedly installed at the end of the support plate away from the support rod. The end of the hinge shaft away from the support plate is rotatably connected to the main adjusting rod, and the main adjusting rod is supported by the support plate and the hinge shaft.

[0011] Furthermore, the mounting ring has a movable groove on the side near the main adjusting rod to provide space for the rotation of the main adjusting rod.

[0012] Furthermore, a main limiting post is fixedly installed on the inner wall of the mounting ring, and the main limiting post is located on the side of the ratchet away from the main adjusting rod. A secondary pawl that meshes with the ratchet is rotatably installed on the end of the main limiting post away from the inner wall of the mounting ring. A secondary limiting post is also fixedly installed on the inner wall of the mounting ring. A secondary tension spring is fixedly installed between the secondary pawl and the secondary limiting post.

[0013] The beneficial effects of this invention are as follows:

[0014] This application provides an agricultural no-till row seeder. During the furrowing process as the seeder body moves forward, if soil conditions change abruptly, the upward movement of the furrow opener drives the limit slide rod to push the auxiliary adjusting rod upward. This, in turn, drives the main adjusting rod to move the main pawl to actuate the ratchet, allowing the powder in the feeding trough to fall onto the soil surface through the feeding pipe and the diversion pipe for marking. This facilitates later workers in locating shallow sowing points and reseeding them, thereby improving the sowing qualification rate. Simultaneously, a Hall gear sensor monitors the ratchet speed in real time. If the furrow opener is affected by straw entanglement or the inability to cut straw, resulting in straw accumulation and affecting the sowing depth, the operator can promptly clean and maintain the furrow opener. This prevents the furrow opener from failing to reach the desired depth for an extended period, leading to large-scale unqualified sowing depths, reducing the probability of missing seedlings, broken rows, or seed burn, and ensuring sowing quality.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] See Figures 1 to 6A no-till seeder for agriculture includes a seeder body 1. A support rod 2 is fixedly mounted on the seeder body 1. Multiple storage boxes for holding seeds are fixedly mounted above the support rod 2. Multiple mounting boxes 4 are fixedly mounted on the support rod 2 by bolts, and each mounting box 4 is adapted to a corresponding storage box. A furrow opener 3 is slidably mounted below the mounting box 4. The bottom of the storage box is fixedly connected to the furrow opener 3 via a conveying pipe. A support shaft 5 is fixedly mounted on the top of the furrow opener 3. A limiting slide rod 7 is fixedly mounted on the top of the support shaft 5, and the limiting slide rod 7 is slidably connected to the mounting box 4 for limiting. A buffer spring 6 is fitted on the outside of the support shaft 5, and the bottom and top ends of the buffer spring 6 are respectively connected to the top of the furrow opener 3 and the mounting box. The bottom of 4 is fixedly connected. During the movement of the strip seeder body 1 driven by the tractor, the furrow opener 3 rotates under the action of friction between itself and the soil to open furrows. At the same time, the seeds in the storage box are fed into the furrow through the conveying pipe to complete the sowing. When the furrow opener 3 encounters hard stones or soil during the movement, causing a sudden increase in pressure, the furrow opener 3 moves upward and drives the limit slide rod 7 to move upward synchronously through the support shaft 5. The buffer spring 6 is compressed to buffer the furrow opener 3 and prevent the furrow opener 3 from being damaged due to sudden pressure changes. After crossing the point, under the action of the furrow opener 3's own weight and the elastic force of the buffer spring 6, the furrow opener 3 will move downward to reset so as to ensure that the furrowing depth meets the furrowing standard in the subsequent furrowing process.

[0025] A storage box 8 is fixedly installed on the side of the support rod 2 away from the mounting box 4, and the inside of the storage box 8 is filled with brightly colored powder. A discharge box 9 is fixedly installed at the bottom of the storage box 8, and a feeding tray 18 is rotatably installed inside the discharge box 9. The storage box 8 and the feeding tray 18 are connected. Multiple material picking slots 19 arranged in a circular array are opened on the outer side of the feeding tray 18. A feeding pipe 20 connected to the feeding tray 18 is fixedly installed at the bottom of the discharge box 9. Two diversion pipes 21 are fixedly connected to the bottom of the feeding pipe 20. Furthermore, the two diversion pipes 21 are inverted V-shaped. Since the storage box 8 is connected to the feeding tray 18, as the feeding tray 18 rotates, the powder stored inside the storage box 8 will enter the various feeding troughs 19. When the feeding trough 19 containing the powder rotates to the connection between the discharge box 9 and the feeding pipe 20, the powder will fall onto the soil surface through the feeding pipe 20 and the diversion pipe 21 to mark the soil. The inverted V-shaped diversion pipe 21 is designed to sprinkle the powder on both sides of the furrow to prevent the powder from falling into the furrow and being buried by the soil.

[0026] A mounting ring 10 is fixedly installed on one side of the discharge box 9. A rotating shaft 12 is rotatably installed at the axis of the mounting ring 10. The end of the diversion pipe 21 near the discharge box 9 moves through the side wall of the discharge box 9 and the mounting ring 10 and is fixedly connected to the feeding tray 18. A ratchet 13 is fixedly installed at the end of the rotating shaft 12 away from the feeding tray 18. When the ratchet 13 rotates, it will drive the feeding tray 18 to rotate synchronously through the rotating shaft 12.

[0027] A mounting post 14 is fixedly mounted on the inner wall of the mounting ring 10. The mounting post 14 is positioned on the side of the ratchet 13 near the support rod 2 and is located above the rotating shaft 12. A main tension spring 16 is fixedly mounted on the end of the mounting post 14 away from the inner wall of the mounting ring 10. A main pawl 15, which meshes with the ratchet 13, is rotatably mounted on the end of the main tension spring 16 away from the mounting post 14. Multiple support plates 1102 are fixedly mounted on the top of the support rod 2, and each support plate 1102 is adapted to a corresponding storage box 8. A hinge shaft 1103 is fixedly mounted on the top of the support plate 1102. The end of the hinge shaft 1103 away from the support plate 1102 is hinged to the main adjustment via a torsion spring (not shown in the figure). The main adjusting rod 11 has a secondary adjusting rod 1101 hinged to one end near the mounting box 4. The secondary adjusting rod 1101 is positioned directly above the limiting slide rod 7, and its bottom end is fitted onto the outside of the limiting slide rod 7 and rotatably connected to it. The mounting ring 10 has a movable groove 17 on one side near the main adjusting rod 11. The end of the main adjusting rod 11 near the mounting ring 10 moves through the movable groove 17 and is fixedly connected to the main pawl 15. Under the action of the torsion spring and the main tension spring 16, when the trencher 3 moves upward without force, the secondary adjusting rod 1101 is in contact with the limiting slide rod 7 and close to the bottom of the mounting box 4, which is the initial position. The position of the main pawl 15 also remains relatively stable.

[0028] When the trencher 3 encounters hard rocks or clods of soil and moves upwards significantly, the trencher 3, via the support shaft 5, drives the limiting slide rod 7 and the auxiliary adjusting rod 1101 to move upwards simultaneously. The auxiliary adjusting rod 1101, through its rotational connection with the main adjusting rod 11, drives the main adjusting rod 11 to rotate counterclockwise around the hinge point between the main adjusting rod 11 and the hinge shaft 1103. Figure 3 Taking this as an example, the main pawl 15 slides along the surface of the ratchet 13 under the tension of the main tension spring 16, so that the main pawl 15 slides on the ratchet 13 to the next tooth block. When the furrow opener 3, support shaft 5 and limit slide rod 7 are reset under their own weight and the elasticity of the buffer spring 6, the main pawl 15 also gradually resets. In this process, the ratchet 13 is quickly turned. When the ratchet 13 is turned, the feeding disc 18 is rotated through the rotating shaft 12, so that the feeding trough 19 containing powder rotates to the connection between the discharge box 9 and the feeding pipe 20, so that the powder can fall onto the soil surface through the feeding pipe 20 and the diversion pipe 21. This marks the places where the furrow depth and sowing depth do not match due to hard stones or soil clods, making it convenient for workers to find shallow sowing points and re-sow them to improve the sowing qualification rate.

[0029] Since the main pawl 15 and the main adjusting rod 11 are rotatably connected, when the main pawl 15 moves downward along the surface of the ratchet 13 under the action of the main adjusting rod 11, the main tension spring 16 pulls on the main pawl 15 to assist it in sliding to the adjacent tooth block. The rotatably connected main pawl 15 can further assist in sliding. Figure 6 For example, when the main pawl 15 rotates around its connection point with the main adjusting rod 11, Figure 6 The position of the main pawl 15 is at the maximum angle of clockwise rotation. Therefore, when the main pawl 15 moves to the next tooth block, the main adjusting rod 11 drives the main pawl 15 to reset and can drive the ratchet 13 to rotate normally.

[0030] A Hall gear sensor (not shown in the figure) is fixedly installed on the inner wall of the mounting ring 10. The Hall gear sensor is electrically connected to the control system of the tractor cab. The Hall gear sensor is located directly above the rotating shaft 12, and the sensing head of the Hall gear sensor corresponds to the tooth tip of the ratchet 13. The ratchet 13 is made of ferromagnetic material. Since there are gaps between the tips of the teeth of the ratchet 13, that is, tooth grooves, the Hall gear sensor is a waterproof speed detection device made using the Hall effect principle. It is usually composed of a Hall element, a permanent magnet and a signal processing circuit. When the current passes through the Hall element perpendicular to the direction of the external magnetic field, a Hall voltage will be generated in the direction perpendicular to the current and the magnetic field. When the ratchet 13 rotates, the tooth block and tooth groove will alternately pass through the sensing surface of the sensor. Due to the different magnetic properties of the ferromagnetic material (tooth block) and air (tooth groove), the magnetic field around the sensor will change periodically. Each change will trigger the sensor to output a complete digital pulse signal. The controller monitors the speed of the ratchet 13 through the received pulse signal. Therefore, the rotational dynamics of the ratchet 13 can be monitored through the Hall gear sensor.

[0031] When the furrow opener 3, support shaft 5, and limit slide bar 7 encounter hard stones or clods of soil and move upwards significantly, causing the main pawl 15 to actuate the ratchet 13 to mark the powder inside the material collection trough 19 onto the soil, the Hall gear sensor also transmits a signal to the control system by monitoring the tips of the teeth on the ratchet 13 to alert the driver. When the furrow opener 3 is entangled in straw or unable to cut the straw, causing the ratchet 13 to fail to rotate properly for furrowing, starting from a decrease in the rotation speed of the furrow opener 3, as the amount of straw increases or the amount of straw accumulated during the movement of the furrow opener 3 increases, the contact area between the furrow opener 3 and the soil increases, leading to an increase in the rotational resistance of the furrow opener 3, which in turn gradually reduces its furrowing force on the soil, thus causing the furrow opener 3, support shaft 5, and limit slide bar 7 to become unstable. Shaft 5 and limit slide bar 7 move slowly upwards until the limit slide bar 7 drives the main pawl 15 to move the ratchet 13 through the secondary adjusting rod 1101 and the main adjusting rod 11. This causes the rotation speed of the ratchet 13 monitored by the Hall gear sensor to decrease. This rotation speed is different from that of the ratchet 13 when the furrow opener 3 encounters hard stones or soil clods, and the difference is significant. Therefore, by monitoring the rotation speed of the ratchet 13, the driver is given an early warning. Real-time monitoring is conducted on the working condition of the furrow opener 3, which affects the furrowing and sowing depth due to straw entanglement or inability to cut the straw. This allows the driver to clean and maintain the furrow opener 3 in a timely manner, preventing the furrow opener 3 from failing to reach the furrowing depth for a long time, resulting in large-scale unqualified sowing depth, reducing the probability of missing seedlings, broken rows, or burned seeds, and ensuring sowing quality.

[0032] A main limiting post 22 is fixedly installed on the inner wall of the mounting ring 10, and the main limiting post 22 is located on the side of the ratchet 13 away from the main adjusting rod 11. A secondary pawl 23, which meshes with the ratchet 13, is rotatably installed at the end of the main limiting post 22 away from the inner wall of the mounting ring 10. A secondary limiting post 24 is also fixedly installed on the inner wall of the mounting ring 10. A secondary tension spring 25 is fixedly installed between the secondary pawl 23 and the secondary limiting post 24. When the main adjusting rod 11 drives the main pawl 15 to slide along the surface of the ratchet 13, since the main pawl 15 is in contact with the outer surface of the ratchet 13, the engagement of the secondary pawl 23 with the ratchet 13 prevents the main pawl 15 from sliding along the surface of the ratchet 13. The friction between the main pawl 15 and the ratchet 13 causes the ratchet 13 to rotate clockwise (towards...). Figure 6 For example, this causes the main pawl 15 to be unable to slide smoothly to the next tooth block. When the main pawl 15 slides to the next tooth block and is reset under the action of the main adjusting rod 11 to push the ratchet 13 to rotate, the ratchet 13 squeezes the secondary pawl 23 and the secondary tension spring 25, causing the secondary pawl 23 to slide to the next tooth block on the surface of the ratchet 13, so as to continue to limit the ratchet 13 and prevent the ratchet 13 from rotating clockwise.

[0033] Working principle:

[0034] As the tractor drives the row seeder 1 forward, the furrow opener 3 rotates under the friction between itself and the soil to open furrows. Simultaneously, seeds from the storage box are fed into the furrows via the delivery pipe, completing the sowing process. When the furrow opener 3 encounters hard rocks or soil during its movement, causing a sudden increase in pressure, the furrow opener 3 moves upward, and the support shaft 5 drives the limit slide rod 7 to move upward synchronously. The buffer spring 6 is compressed to cushion the furrow opener 3 and prevent damage due to sudden pressure changes. Under the action of the torsion spring and the main tension spring 16, the ratchet 13 drives the rotating shaft 12 and the feeding disc 18 to rotate, thus limiting the slide rod 7. Rod 7 drives the main pawl 15 to move the ratchet 13 via the secondary adjusting rod 1101 and the main adjusting rod 11, so that the material trough 19 containing powder rotates to the connection between the discharge box 9 and the discharge pipe 20, allowing the powder to fall onto the soil surface through the discharge pipe 20 and the diversion pipe 21. This marks the areas where the furrowing depth and sowing depth do not match due to hard stones or soil clods, making it easier for workers to find shallow sowing points and re-sow them to improve the sowing qualification rate. After crossing the point, under the action of the furrow opener 3's own weight and the elastic force of the buffer spring 6, the furrow opener 3 will move down and reset to ensure that the furrowing depth meets the furrowing standard during subsequent furrowing processes.

[0035] When the furrow opener 3, support shaft 5, and limit slide bar 7 encounter hard stones or clods of soil and move upwards significantly, causing the main pawl 15 to actuate the ratchet 13 to mark the powder inside the material trough 19 onto the soil, the Hall gear sensor also transmits a signal to the control system by monitoring the tips of the teeth on the ratchet 13 to alert the driver. When the furrow opener 3 is entangled in straw or unable to cut the straw, preventing the ratchet 13 from rotating properly to open the furrow, starting from a decrease in the rotation speed of the furrow opener 3, as the amount of straw increases or the amount of straw accumulated during the movement of the furrow opener 3 increases, the contact area between the furrow opener 3 and the soil increases, leading to an increase in the rotational resistance of the furrow opener 3, which in turn gradually reduces its furrowing force on the soil, thus causing the furrow opener 3, support shaft 5, and limit slide bar 7 to become unstable. The support shaft 5 and the limiting slide bar 7 move slowly upwards until the limiting slide bar 7 drives the main pawl 15 to move the ratchet 13 through the secondary adjusting rod 1101 and the main adjusting rod 11. This causes the rotation speed of the ratchet 13 monitored by the Hall gear sensor to decrease. This rotation speed is different from that of the ratchet 13 when the furrow opener 3 encounters hard stones or soil clods, and the difference is significant. Therefore, by monitoring the rotation speed of the ratchet 13, the driver is given an early warning. This allows for real-time monitoring of the furrow opener 3's operation when straw is entangled or unable to be cut, resulting in straw accumulation that affects the furrowing and sowing depth. This enables the driver to clean and maintain the furrow opener 3 in a timely manner, preventing the furrow opener 3 from failing to reach the furrowing depth for a long time, which would lead to large-scale unqualified sowing depth, reduce the probability of missing seedlings, broken rows, or burned seeds, and ensure sowing quality.
