Description

Technical Field

[0001] This utility model relates to the field of speed control device technology, and in particular to an integrated right-angle servo speed control assembly. Background Technology

[0002] Currently, crop sowing mainly relies on manual sowing, which is laborious, time-consuming, inefficient, and wasteful of seeds. With the development and progress of agricultural technology, agricultural machinery with seed spreaders has appeared on the market. Seed spreaders, also known as seeders, can greatly improve sowing efficiency.

[0003] Current agricultural machinery typically uses stepper motors to power and control the seed distributor. However, stepper motors are not very accurate in moving on uneven farmland, resulting in large sowing errors and making it difficult to meet sowing needs. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated right-angle servo speed control assembly, which aims to solve the problem that existing agricultural machinery uses stepper motors to power the seed distributor, resulting in low accuracy of movement on uneven farmland, large sowing errors, and difficulty in meeting sowing needs.

[0005] To achieve the above objectives, this utility model provides an integrated right-angle servo speed control assembly, including a hexagonal bolt and a speed control component, wherein the speed control component includes a servo motor, a right-angle steering gear, and a drive gear;

[0006] The input shaft of the right-angle steering gear is fixedly connected to the output shaft of the servo motor and is located on the side of the servo motor. A flat key is provided on the outer side of the output shaft of the right-angle steering gear, and a screw hole is provided on the inner side of the output shaft of the right-angle steering gear. The drive gear is located on the outer side of the right-angle steering gear, and a keyway is provided on the inner side of the drive gear. The hexagonal bolt is set in the screw hole.

[0007] The speed regulating component further includes a shim; the shim is disposed between the hexagonal bolt and the drive gear.

[0008] The speed regulating component further includes a flat washer; the flat washer is disposed between the hexagonal bolt and the gasket.

[0009] The speed regulating component further includes a spring washer; the spring washer is disposed between the hexagonal bolt and the flat washer.

[0010] The integrated right-angle servo speed control assembly further includes a heat dissipation component; the heat dissipation component includes a mounting base, a central tube, a flexible tube, two U-shaped tubes, a connecting rod, and a mounting bolt; the mounting base is fixedly connected to the servo motor and located on the side of the servo motor; the central tube is located on the side of the servo motor; the flexible tube is fixedly connected to and communicates with the central tube and is located on the side of the central tube; the two U-shaped tubes are respectively fixedly connected to and communicate with the central tube and are located on both sides of the central tube, and the U-shaped tubes have multiple air vents on the side near the servo motor; the connecting rod is fixedly connected to the two U-shaped tubes respectively and is located between the two U-shaped tubes; the mounting bolt is threadedly connected to the connecting rod and threadedly connected to the mounting base, and is located between the connecting rod and the mounting base.

[0011] This utility model discloses an integrated right-angle servo speed control assembly. The drive gear is mounted on the output shaft of the right-angle steering gear, and a flat key is placed in the keyway. Hexagonal bolts are then tightened into the threaded holes. Connecting bolts limit and fix the drive gear on the output shaft of the right-angle steering gear. A servo motor provides power to drive the output shaft of the right-angle steering gear and the drive gear to rotate. The drive gear, through a gear transmission structure, drives a seed distributor to sow seeds on farmland. This utility model uses a servo motor as the power source. Servo motors have excellent speed control performance, with superior braking and starting characteristics. With a wide range of speeds, smooth stepless speed regulation is easily achieved. Simultaneously, the speed regulation accuracy of servo motors is relatively high, enabling them to quickly and accurately adjust the rotational speed according to the control signal requirements, meeting the precise speed demands of different application scenarios. The use of servo motors minimizes errors when sowing on uneven farmland. Smaller models of servo motors and right-angle steering gears can be selected, achieving miniaturization of the mechanism. Through these methods, the problem of existing agricultural machinery using stepper motors to power the seed distributor, resulting in low accuracy on uneven farmland and significant sowing errors, fails to meet sowing requirements.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] This utility model provides an integrated right-angle servo speed control assembly, including a hexagonal bolt 1, a speed control component, and a heat dissipation component. The speed control component includes a servo motor 2, a right-angle steering gear 3, a drive gear 4, a shim 7, a flat washer 8, and a spring washer 9. The heat dissipation component includes a mounting base 10, a central tube 11, a flexible hose 12, two U-shaped tubes 13, a connecting rod 14, and a mounting bolt 15. The aforementioned solution solves the problem that existing agricultural machinery, which uses a stepper motor to power the seed distributor, has low accuracy in traveling on uneven farmland, resulting in large sowing errors and making it difficult to meet sowing requirements.

[0023] In this specific embodiment, the input shaft of the right-angle steering gear 3 and the output shaft of the servo motor 2 are fixedly connected and located on the side of the servo motor 2. A flat key 5 is provided on the outer side of the output shaft of the right-angle steering gear 3, and a screw hole is provided on the inner side of the output shaft of the right-angle steering gear 3. The drive gear 4 is located on the outer side of the right-angle steering gear 3, and a keyway 6 is provided on the inner side of the drive gear 4. The hexagonal bolt 1 is set in the screw hole. The drive gear 4 is fitted onto the output shaft of the right-angle steering gear 3, and the flat key 5 is placed in the keyway 6. Then, the hexagonal bolt 1 is tightened in the screw hole. The connecting bolt limits and fixes the drive gear 4 on the output shaft of the right-angle steering gear 3. The servo motor 2 provides power to drive the output shaft of the right-angle steering gear 3 and the drive gear 4 to rotate. The drive gear 4 drives the seed distributor to move through the gear transmission structure, thereby sowing seeds on the farmland. This utility model uses the servo motor 2 as the power source. The servo motor 2 has good speed regulation performance, excellent braking and starting characteristics, and a wide speed regulation range. Smooth stepless speed regulation is easily achieved over a wide range. At the same time, the speed regulation accuracy of servo motor 2 is relatively high. It can quickly and accurately adjust the speed according to the requirements of the control signal to meet the precise speed requirements of different application scenarios. By using servo motor 2, the error is small when sowing on uneven farmland. Servo motor 2 and right-angle steering gear 3 can be selected in smaller sizes to achieve miniaturization of the mechanism. In the above way, the problem of low accuracy of existing agricultural machinery on uneven farmland, resulting in large sowing errors and difficulty in meeting sowing requirements, is solved because the existing agricultural machinery uses stepper motors to power the rotation of the seed spreader.

[0024] The gasket 7 is disposed between the hexagonal bolt 1 and the drive gear 4. The gasket 7 can fill the minute gaps and unevenness between the connecting surfaces of the hexagonal bolt 1 and the drive gear 4.

[0025] Secondly, the flat washer 8 is disposed between the hexagonal bolt 1 and the washer 7. The flat washer 8 increases the contact area between the washer 7 and the hexagonal bolt 1, which can reduce the pressure per unit area, prevent the hexagonal bolt 1 from causing indentations or damage to the surface of the drive gear 4 during tightening, and also improve the stability of the connection.

[0026] Meanwhile, the spring washer 9 is disposed between the hexagonal bolt 1 and the flat washer 8. The spring washer 9 is elastic, and after the hexagonal bolt 1 is tightened, it will generate elastic deformation, providing a continuous axial force. This axial force can compensate for the loosening of the hexagonal bolt 1 caused by factors such as tensile deformation and temperature changes after the connecting bolt is subjected to force, thereby effectively preventing the hexagonal bolt 1 from loosening on its own due to external forces such as vibration and impact, and ensuring the reliability of the connection.

[0027] Additionally, the heat dissipation assembly includes a mounting base 10, a central tube 11, a flexible hose 12, two U-shaped tubes 13, a connecting rod 14, and a mounting bolt 15. The mounting base 10 is fixedly connected to the servo motor 2 and is located on the side of the servo motor 2. The central tube 11 is located on the side of the servo motor 2. The flexible hose 12 is fixedly connected to and communicates with the central tube 11 and is located on the side of the central tube 11. The two U-shaped tubes 13 are respectively fixedly connected to and communicate with the central tube 11 and are located on both sides of the central tube 11. The U-shaped tubes 13 have multiple air vents 16 on the side near the servo motor 2. The connecting rod 14 is fixedly connected to the two U-shaped tubes 13 and is located between the two U-shaped tubes 13. The mounting bolt 15 is threadedly connected to the connecting rod 14 and threadedly connected to the mounting base 10, and is located between the connecting rod 14 and the mounting base 10. The mounting base 10 is fixed to the outside of the servo motor 2 by welding. The U-shaped tube 13 is U-shaped. When installing the heat dissipation component, the U-shaped tube 13 is suspended from top to bottom and placed outside the servo motor 2, so that the U-shaped tube 13 is in the upper, left and right directions of the servo motor 2. Then, the mounting bolt 15 is passed through the connecting rod 14 and screwed onto the mounting base 10, thereby fixing the U-shaped tube 13 to the outside of the servo motor 2. The U-shaped tube 13 and the middle tube 11 have cavities for air circulation inside. A fan is installed on the agricultural machinery, and the hose 12 is connected to the air outlet of the fan. The fan guides the airflow through the hose 12 into the middle tube 11 and the two U-shaped tubes 13, and finally blows it to the outside of the servo motor 2 from the multiple air outlets 16, thereby cooling the servo motor 2 and preventing the servo motor 2 from being damaged due to excessive temperature during long-term operation. This application uses the connecting rod 14, the mounting bolt 15 and the mounting base 10 to fix the U-shaped tube 13, which facilitates the installation and disassembly of the U-shaped tube 13.

[0028] In using this invention, the drive gear 4 is fitted onto the output shaft of the right-angle steering gear 3, and the flat key 5 is placed in the keyway 6. Then, the spring washer 9, the flat washer 8, and the shim 7 are sequentially fitted onto the hexagonal bolt 1, and the hexagonal bolt 1 is tightened into the screw hole. The connecting bolt limits and fixes the drive gear 4 onto the output shaft of the right-angle steering gear 3. The servo motor 2 provides power to drive the output shaft of the right-angle steering gear 3 and the drive gear 4 to rotate. The drive gear 4 drives the seed distributor via a gear transmission structure, thereby sowing seeds on farmland. This invention uses the servo motor 2 as the power source, and the servo motor 2 has good adjustment... The servo motor 2 boasts excellent speed performance, braking and starting characteristics, and a wide speed range, making it easy to achieve smooth stepless speed regulation within a broad range. Simultaneously, the servo motor 2 exhibits relatively high speed regulation accuracy, enabling it to quickly and accurately adjust the rotational speed according to control signal requirements, meeting the precise speed demands of different application scenarios. The use of the servo motor 2 minimizes errors when sowing on uneven farmland. Furthermore, smaller models of the servo motor 2 and right-angle steering gear 3 can be selected to achieve miniaturization of the mechanism. Through these methods, the problem of existing agricultural machinery using stepper motors to power the seed distributor, resulting in low accuracy on uneven farmland and significant sowing errors, fails to meet sowing requirements.
