Description

Technical Field

[0001] This utility model belongs to the field of tobacco transplanting technology, and in particular relates to a water injection system for tobacco seedling transplanting. Background Technology

[0002] Well-pit transplanting is a highly efficient and practical method for transplanting flue-cured tobacco. 3-5 days before transplanting, specialized machinery is used to dig the wells. The soil moisture content should be such that it can be formed into a ball when squeezed in hand, but crumbles easily when lightly tossed to the ground. If the soil moisture content is insufficient, manual replenishment can be done the day before digging the wells. After the wells are completed, the tobacco seedlings are placed inside.

[0003] For example, CN221203228U discloses an automatic counting and hole-planting device. This device includes a handle, a rod, a main spring, a hole-planting head, a counter, and a distance-fixing unit. The handle is a cylindrical body with one closed end and one open end. One end of the rod is inserted into the open end of the handle and connected to the inner wall of the closed end of the handle via the main spring. The other end of the rod is equipped with the hole-planting head. The counter is an electronic counter, including a meter and a sensor connected by a circuit, both located on the side of the handle. The sensing end of the sensor extends into the handle. The distance-fixing unit is located on the rod and close to the hole-planting head. The automatic counting and hole-planting device provided by this utility model solves the problems of cumbersome operation and high error rate in existing methods of counting the number of transplanted tobacco seedlings.

[0004] This drilling tool allows for the drilling of wells. After this step, it is often necessary to inject fertilizer into the well. The injection of fertilizer directly affects the subsequent growth of tobacco seedlings. Currently, some people inject water manually. Although this method has low equipment costs, it is labor-inefficient and cannot guarantee the consistency of water volume in each well.

[0005] Of course, there are also existing technologies that combine transplanting equipment and watering equipment together, but these types of equipment are often less flexible and less adaptable. Utility Model Content

[0006] The present invention aims to provide a simple and effective watering system for transplanting tobacco seedlings.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a water injection system for tobacco seedling transplanting, including a fixed water tank and a mobile vehicle body, wherein the mobile vehicle body is equipped with a water distribution tank, a water pump and a hose connected to the water pump; the fixed water tank is used to supply water to the water distribution tank;

[0008] The water distribution tank is connected to a horizontally installed horizontal pipe, which is connected to a flexible hose. The flexible hose is connected to the water distribution tank via a water pump.

[0012] The horizontal pipe includes a tee connector and two side pipes. The flexible hose is connected to one end of the tee connector, and the two side pipes are connected to the remaining two terminals of the tee connector respectively.

[0013] The fixed water tank is located in the tobacco field, and the fixed water tank and the distribution water tank are equipped with quick-connect fittings that work together.

[0016] The bottom of the mobile vehicle is equipped with tracks, and the mobile vehicle is equipped with track motors, which drive the tracks; the subprocessor outputs signals to drive the track motors.

[0017] Through the above technical solutions, the technical effects of this utility model are as follows: 1.

[0023] like Figures 1-4 As shown, a watering system for tobacco seedling transplanting is used to water tobacco seedlings before transplanting. The system includes a fixed water tank 7 and a mobile vehicle 1. The fixed water tank 7 is fixedly located in the center of the tobacco field and is used to add water at regular intervals. It is convenient to use in large tobacco fields.

[0024] The mobile vehicle body 1 is equipped with a water tank 2, a water pump, a hose 3, and a horizontal pipe 4.

[0025] Water distribution tank 2 is used to move within the tobacco field under the drive of mobile vehicle 1. When the water level in water distribution tank 2 is insufficient, mobile vehicle 1 is moved to fixed water tank 7 to add water. In order to facilitate the connection between water distribution tank 2 and fixed water tank 7, quick connectors are provided on fixed water tank 7 and water distribution tank 2. The quick connectors are commercially available products, and this embodiment does not involve any improvement to the quick connectors.

[0026] To detect the water level in the fixed water tank 7, a first liquid level sensor, specifically an ultrasonic liquid level sensor, is installed inside the tank. The signal output terminal of the first liquid level sensor is connected to a main processor, which outputs a signal to a backend system. Thus, the first liquid level sensor collects the water level in the fixed water tank 7 and transmits the collected value to the main processor. The main processor outputs a signal to the backend system, determining whether the water level is sufficient based on the received signal. If the water level is insufficient, it outputs a signal to the backend system, allowing staff to promptly replenish water or perform other operations on the fixed water tank 7.

[0027] In this embodiment, the main processor includes an STM32 microcontroller, and a Wi-Fi module (model Esp826) is connected to the microcontroller. The connection method between the two is a mature existing technology, specifically: the microcontroller's serial port is connected to the Wi-Fi module, so that the microcontroller transmits the signal to the wireless router through the Wi-Fi module, thereby transmitting the signal to the backend.

[0028] The ultrasonic level sensor transmits the collected level signal to the microcontroller, which then uses wireless communication to transmit the signal to the backend – a mature existing technology, and this embodiment does not involve any improvements to this part. Specifically, the connection between the first level sensor and the microcontroller is as follows: the Trig trigger pin of the ultrasonic level sensor is connected to one GPIO pin of the microcontroller, and the Echo receiver pin of the ultrasonic level sensor is connected to another GPIO pin of the microcontroller U1. This allows the distance between the ultrasonic sensor and the liquid level to be determined based on the transmitted and received ultrasonic signals, thereby determining whether the liquid level is below a set value and, consequently, whether the water volume is sufficient.

[0029] In addition, a second liquid level sensor is installed inside the water tank 2. The signal output terminal of the second liquid level sensor is connected to a sub-processor, and the signal output terminal of the sub-processor has an alarm circuit. The sub-processor includes an STM32 microcontroller. The second liquid level sensor transmits the collected liquid level signal to the sub-microcontroller, and the sub-microcontroller outputs a signal to the alarm circuit for display. This is a mature existing technology, and this embodiment does not involve any improvement to this part.

[0030] In this embodiment, the second liquid level sensor, like the first liquid level sensor, can be an ultrasonic liquid level sensor. Furthermore, the connection method between the second liquid level sensor and the microcontroller of the sub-processor is the same as the connection method between the first liquid level sensor and the main microcontroller, and will not be described again. The alarm circuit in this embodiment is an audible and visual alarm circuit, which includes a light-emitting diode (LED) and a buzzer. Driving the LED and buzzer with a microcontroller is a mature existing technology, and its implementation will not be described in detail in this embodiment.

[0031] As an alternative to this embodiment, for further ease of use, tracks are provided at the bottom of the mobile vehicle body 1. The tracks drive the movement of the mobile vehicle body 1. A track motor is provided on the mobile vehicle body 1, and the track motor drives the tracks. The sub-processor outputs a signal to drive the track motor. Thus, when the liquid level in the water tank 2 is insufficient, the sub-processor outputs a signal to stop the track motor, thereby avoiding poor watering results. In this embodiment, to realize the microcontroller's drive of the track motor, a motor driver chip (model L298N) is connected to the signal output terminal of the microcontroller. The motor driver chip drives the track motor to stop or start. The operation of the motor by the microcontroller through the motor driver chip is a mature existing technology, and will not be described in detail in this embodiment.

[0032] A flexible hose 3 is connected to the outlet of the water pump, and a horizontal pipe 4 is connected to the flexible hose 3. To facilitate the connection between the horizontal pipe 4 and the flexible hose 3, the horizontal pipe 4 includes a T-joint and two side pipes. The flexible hose 3 is connected to one end of the T-joint, and the two side pipes are connected to the remaining two ends of the T-joint. The inlet of the water pump is connected to a distribution tank, thereby drawing water from the distribution tank into the flexible hose 3, which then enters the horizontal pipe 4.

[0033] To enable the horizontal tube 4 to be installed on the mobile vehicle body 1, a vertically arranged electric push rod 8 is installed on the mobile vehicle body 1. The telescopic end of the vertical electric push rod 8 is connected to the horizontal tube 4, so that the horizontal tube 4 can be raised and lowered through the vertical electric push rod 8 to ensure the working effect.

[0034] An L-shaped watering pipe 10 is connected to the end of the horizontal pipe 4. One end of the watering pipe 10 is inserted into the horizontal pipe 4 and is slidably and sealed inside the horizontal pipe 4. The other end is equipped with a downward-facing water injection head 10. In this embodiment, to enable the watering pipe 10 to slide within the horizontal pipe 4, a horizontal electric push rod 9 is installed on the horizontal pipe 4. The telescopic end of the horizontal electric push rod 9 is connected to the watering pipe 10. The horizontal electric push rod 9 can drive the watering pipe 10 to slide within the horizontal pipe 4, thereby increasing or decreasing the length of the watering pipe 10 extending out of the horizontal pipe 4 to adapt to different plots of land. Before operation, the telescopic end of the horizontal electric push rod 9 can be extended or retracted according to the characteristics of the plot, so that the water injection head 10 on the horizontal pipe 4 can be positioned just above the well pit 6 on the ridge 5, increasing the effective range.

[0035] The water injection head 10 is positioned downwards, allowing water from it to fall directly into the well pit 6. To control the water level in the water injection head 10, a solenoid valve is connected to it, which controls whether the water injection head 10 is open or closed.

[0036] Meanwhile, to detect whether the water injection head 10 has reached above the well pit 6, a ranging module 11 is connected to the water injection head 10. The signal output terminal of the ranging module 11 is connected to the microcontroller of the subprocessor, and the microcontroller outputs a signal to control the operation of the solenoid valve. The microcontroller output signal controlling the solenoid valve is a mature existing technology and will not be described in detail in this embodiment. During the movement of the vehicle, when the well pit 6 is not encountered, the distance measured by the ranging module 11 is relatively short; when the well pit 6 is encountered, the distance measured by the ranging module 11 suddenly increases. Based on this principle, it is determined whether the vehicle has reached above the well pit 6.

[0037] The ranging module 11 includes an ultrasonic ranging sensor. The ultrasonic ranging sensor transmits the collected distance information to the microcontroller. The microcontroller outputs a signal to drive the solenoid valve.

[0038] As an alternative to this embodiment, to accommodate the lifting and lowering of the horizontal pipe 4, a winding shaft 12 is rotatably mounted on the moving vehicle body 11, and the flexible hose 3 is wound around the winding shaft 12. Simultaneously, a motor drives the rotation of the winding shaft 12; in this embodiment, the motor drives the rotation of the winding shaft 12 via a chain 18.

[0039] During operation, the winding shaft 12 rotates clockwise, causing the hose 3 to come off the winding shaft 12 slightly to accommodate the lowering of the horizontal pipe 4; the winding shaft 12 rotates counterclockwise, causing the hose 3 to wrap around the winding shaft 12 to accommodate the raising of the horizontal pipe 4. Protective plates 13 are fixed on both sides of the winding shaft 12 to prevent the hose 3 from falling off the winding shaft 12.

[0040] The working process is as follows: the mobile vehicle 1 moves through the tobacco seedling field driven by the track 8, the water pump is started, and the vertical electric push rod 8 is adjusted according to the height of the ridge 5 to control the distance between the water injection head 10 and the tobacco seedling ridge 5; at the same time, the horizontal electric push rod 9 is adjusted so that the water injection head 10 can be located above the well pit 6. Since the well pits 6 are arranged in a row, there is no need to adjust the horizontal electric push rod 9 and the vertical electric push rod 8 during the movement of the vehicle.

[0041] As the vehicle moves, the distance measuring module 11 on the water injection head 10 measures the distance to the area below and transmits the collected distance information to the microcontroller. Based on the distance signal, the microcontroller determines that it has reached above the well pit 6. At this point, the microcontroller outputs a signal causing the drive motor of the track 8 to stop for a set time, and the solenoid valve to open for a set time, allowing water to be injected from the water injection head 10 into the well pit 6. After the set time is reached, the drive motor of the track resumes operation, the vehicle continues to move, and the solenoid valve closes.

[0042] Among them, using a microcontroller to control the motor is a mature existing technology. It only requires connecting a motor driver chip to the signal output terminal of the microcontroller. A motor driver chip of model L298N can be selected to drive the motor.

[0043] Example 2 differs from Example 1 in that: in this example, the microcontroller is an STM32 series microcontroller; the ultrasonic ranging sensor is an HC-SR04 ultrasonic ranging sensor, the power supply pin of the ultrasonic ranging sensor is connected to the power supply pin of the microcontroller, and the ground pin of the ultrasonic ranging sensor is connected to the ground pin of the microcontroller.

[0044] Meanwhile, the Trig trigger pin of the ultrasonic ranging sensor is connected to one GPIO pin of the microcontroller, and the Echo receiver pin of the ultrasonic ranging sensor is connected to another GPIO pin of the microcontroller U1, so as to determine the distance between the sensor and the tobacco seedling based on the transmitted and received ultrasonic signals.

[0045] To enable the microcontroller to drive the solenoid valve, a solenoid valve drive circuit is connected to the signal output terminal of the microcontroller. The solenoid valve drive circuit drives the solenoid valve to operate, thereby controlling the water spray from the water injection head 10. Simultaneously, a motor driver chip (model L298N) is connected to the microcontroller to control the drive motor of the track.

[0046] This utility model discloses a water injection device for tobacco seedling transplanting, which can inject water into the planting hole before transplanting the tobacco seedlings. The water injection volume is uniform, which ensures the water injection effect. At the same time, it can be adjusted according to the height of the ridge, making it widely applicable. The mechanical water injection greatly reduces the intensity of manual labor and improves the efficiency of operation.
