Abstract
Description
Technical Field
[0001] This utility model is an automatic control system for the turning platform of a rice transplanter. Background Technology
[0002] A rice transplanter is an agricultural machine used to plant rice seedlings into paddy fields. During planting, a mechanical claw first removes several rice seedlings from a seedbed and plants them into the soil. To maintain a right angle between the seedbed and the ground, the front end of the claw must move in an elliptical curve. The movement is accomplished by a planetary mechanism using rotary or variable gears, while a forward engine drives these moving parts. The transplanter must have non-slip wheels and a floating design to move on the soil. If planting in rows, seedlings are taken from specific seed boxes and planted mechanically.
[0003] Currently, the working conditions of rice transplanters in China are complex and varied. When the rice transplanter turns around at the edge of the field, the driver needs to manually operate the mechanical control lever to raise and lower the seedling platform, which is cumbersome and frequent. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automatic control system for the turning platform of a rice transplanter.
[0005] An automatic control system for a rice transplanter turning seedling platform includes an information acquisition module, a controller, and an actuator. The information acquisition module includes a seedling platform height acquisition module and a walking status acquisition module. The controller receives data signals from the information acquisition module and sends corresponding control signals to the actuator. The walking status acquisition module includes a reverse sensing switch, a steering wheel angle sensor, and a walking speed sensor. The reverse sensing switch senses whether the rice transplanter is in a reverse state, the steering wheel angle sensor senses the rotation angle of the steering wheel, and the walking speed sensor senses the walking speed of the rice transplanter.
[0006] Furthermore, the seedling platform height acquisition module includes a seedling platform angle sensor, which is used to sense the rotation angle of the seedling platform. The rotation angle corresponds to the corresponding height. When the seedling platform is at a high position, the seedling platform angle sensor sends a high position signal, and when the seedling platform is at a low position, the seedling platform angle sensor sends a low position signal.
[0007] Furthermore, the actuator includes a motor push rod.
[0008] Furthermore, when the controller senses the reverse signal and low position signal from the reverse sensor switch, the controller controls the electric push rod to raise the seedling platform.
[0009] Furthermore, when the steering wheel is rotated to a predetermined angle, a turning signal is sent. When the controller senses both the turning signal and the low position signal at the same time, the controller controls the electric push rod to raise the seedling platform.
[0010] Furthermore, when the steering wheel rotation angle is within the predetermined range, a straight-ahead signal will be emitted. When the controller senses both the straight-ahead signal and the high-position signal at the same time, the controller will control the push rod to lower the seedling platform.
[0011] Beneficial effects: Compared with the prior art, the present invention has the following advantages:
[0012] Through the coordinated operation of the information acquisition module, controller, and actuator, the system can automatically adjust according to the walking status of the rice transplanter and the height of the seedling platform, reducing reliance on manual operation and improving work efficiency.
[0013] The system uses a variety of sensors (such as steering wheel angle sensor, walking speed sensor, seedling platform angle sensor, etc.) to accurately collect information, ensuring that the controller can receive accurate data signals, thereby sending precise control commands to the actuator to achieve precise adjustment of the seedling platform height.
[0014] The system can sense the rice transplanter's backward movement and the steering wheel's rotation angle. When the rice transplanter is in backward or turning around, it can automatically raise the seedling platform to prevent the platform from colliding with the ground or other obstacles, thus improving operational safety.
[0015] The system can automatically adjust according to different walking speeds and seedbed heights to adapt to different working environments and needs, thus improving the system's flexibility and adaptability.
[0016] An integrated control system enables intelligent management of the turning platform of rice transplanters, improving the level of intelligent agricultural production and reducing labor costs.
[0017] The system's modules are relatively independent, which facilitates troubleshooting and maintenance, reducing maintenance costs and time. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of an automatic control system for a rice transplanter's turning platform. Detailed Implementation
[0019] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0020] An automatic control system for a rice transplanter turning seedling platform includes an information acquisition module, a controller, and an actuator. The information acquisition module includes a seedling platform height acquisition module and a walking status acquisition module. The controller receives data signals from the information acquisition module and sends corresponding control signals to the actuator. The walking status acquisition module includes a reverse sensing switch, a steering wheel angle sensor, and a walking speed sensor. The reverse sensing switch senses whether the rice transplanter is in a reverse state, the steering wheel angle sensor senses the rotation angle of the steering wheel, and the walking speed sensor senses the walking speed of the rice transplanter.
[0021] In this example, the seedling platform height acquisition module includes a seedling platform angle sensor, which is used to sense the rotation angle of the seedling platform. The rotation angle corresponds to the corresponding height. When the seedling platform is at a high position, the seedling platform angle sensor sends a high position signal, and when the seedling platform is at a low position, the seedling platform angle sensor sends a low position signal.
[0022] In this example, the actuator includes a motor push rod.
[0023] In this example, when the controller senses the reverse signal and low position signal from the reverse sensor switch, the controller controls the electric push rod to raise the seedling platform.
[0024] In this example, when the steering wheel is rotated to a predetermined angle, a turning signal is sent. When the controller senses both the turning signal and the low position signal at the same time, the controller controls the electric push rod to raise the seedling platform.
[0025] In this example, when the steering wheel rotation angle is within a predetermined range, a straight-ahead signal will be emitted. When the controller senses both the straight-ahead signal and the high-position signal at the same time, the controller controls the push lever to lower the seedling platform.
