Description

Technical Field

[0001] This utility model belongs to the field of tobacco irrigation technology, and in particular relates to a sprinkler system for irrigation of tobacco fields in the middle and late stages. Background Technology

[0002] Irrigation of tobacco plants is a crucial step in the tobacco planting process. The effectiveness of irrigation in the middle and later stages of tobacco plant growth directly affects the maturity of tobacco leaves. Tobacco plants mostly grow in pits and cellars. During the maintenance of tobacco fields, the fields are often directly irrigated. This method has low equipment costs, but the irrigation effect is poor and water is wasted.

[0003] Mechanized irrigation methods, such as the current sprinkler irrigation, which sprays water onto tobacco plants through nozzles to simulate rainfall and provides even watering, require significant investment in equipment. This necessitates placing sprinkler pipes within the tobacco field for irrigation, and subsequent replanting of tobacco plants puts considerable strain on these pipes. Another example is the current well-cellar watering system, which only injects water into the tobacco plants and cannot be used for spraying.

[0004] For example, patent application CN119014247A discloses an adjustable atomizing spray device, relating to the field of tobacco planting technology. It includes a main body of a mounting bracket spanning both sides of the planting area. The mounting bracket is equipped with an atomizing spray mechanism and a root spray mechanism. The atomizing spray mechanism includes a drive unit, a height adjustment unit, and an atomizing spray unit. The drive unit adjusts the spray height of the atomizing spray unit to accommodate different plants. Compared to conventional direct irrigation, atomizing spraying saves water. The atomized water is more easily absorbed by the plant leaves, promoting photosynthesis. While spraying the leaves, it also irrigates the roots, increasing the plant's water absorption rate and ensuring the humidity of the soil (growing environment). This design uses a uniform watering method to improve the water absorption rate of the soil and tobacco plants, while avoiding water loss, water consumption, and seedling burn caused by direct irrigation. Although it can spray water on the tobacco plants from above, it requires many spray heads, which will undoubtedly increase the equipment cost. At the same time, its function is limited and it cannot inject water into the tobacco plant holes. Subsequent watering of the tobacco plant holes will require the use of other equipment, which will further increase the equipment purchase cost. Utility Model Content

[0025] Sprinkler irrigation equipment for tobacco fields in the middle and late stages, such as Figures 1-5 As shown, this device can irrigate tobacco plants 2 by simulating rainfall and regulating temperature to provide sufficient moisture to the tobacco plants 2. It can also inject a certain amount of water into wells 7 when they are encountered. These two methods can improve the irrigation effect.

[0026] The equipment includes a vehicle body that can travel between tobacco plant rows 1. The bottom of the vehicle body is equipped with tracks 8, meaning that the movement of the vehicle body is driven by the tracks 8.

[0027] An electric motor is mounted on the vehicle body, which powers the devices on the vehicle and the tracks 8. A water tank 3, a water pump, and a gantry 15 are also mounted on the vehicle body. The water pump's inlet is connected to the water tank 3, allowing water to be drawn from the tank for irrigation. The water pump is not shown in the diagram.

[0028] The gantry frame 15 is equipped with a water-spraying component and a water-spraying component. The water-spraying component simulates rainfall to irrigate the tobacco plants 2, while the water-spraying component can inject water into the well pits 7 in the tobacco field.

[0029] The water spraying assembly includes four spray pipes 5 that are rotatably arranged in the horizontal direction. In this embodiment, the four spray pipes 5 are evenly distributed in the horizontal direction, and are arranged perpendicularly to each other in the horizontal direction. Each spray pipe 5 is equipped with a downward-facing spray head 4. In use, the spray pipes 5 rotate in the horizontal direction, causing the spray heads 4 to rotate in the horizontal direction, thereby increasing the effective range of the spray.

[0030] To enable the spray pipes 5 to work, in this embodiment, the ends of the four spray pipes 5 need to be connected together through a 5-way connector 11. At the same time, a rotary connector 21 is connected to the 5-way connector 11. One end of the rotary connector 21 is connected to the 5-way connector 11, and the other end is connected to a water pipe. A valve is installed on the water pipe, which can control whether water enters the water pipe. At the same time, the water pipe is connected to the water tank 3 through a water pump.

[0031] To achieve the rotation of the spray pipe 5, a rotating shaft is fitted outside the rotating end of the rotary joint 21. The rotating shaft is keyed to the rotating end of the rotary joint 21, allowing it to rotate together with the rotating end of the rotary joint 21. A gear 12 is connected to the rotating shaft, and the gear 12 is keyed to the rotating shaft, allowing them to rotate synchronously. Side gears 13 mesh on both sides of the gear 12, and either side gear 13 is connected to the motor via a chain 18. When the motor operates, it drives the side gear 13 to rotate, which in turn drives the gear 12. The rotation of the gear 12 drives the rotating shaft, which in turn drives the rotating end of the rotary joint 21. The rotating end of the rotary joint 21 then drives the 5-way connector 11, which in turn drives the spray pipe 5, ultimately rotating the spray head 4 and achieving wide-area atomized spraying.

[0032] Water is pumped from the water tank into the water pipe, then through the rotary joint 21 into the spray pipe 5, and finally out of the spray head 4.

[0033] In addition, the water spray assembly includes a horizontally arranged horizontal pipe 6. To enable the horizontal pipe 6 to be installed on the gantry frame 15, a vertically arranged vertical electric push rod 9 is installed on the gantry frame 15. The telescopic end of the vertical electric push rod 9 is connected to the horizontal pipe 6, so that the horizontal pipe 6 can be raised and lowered through the vertical electric push rod 9 to ensure the working effect.

[0034] An L-shaped watering pipe 10 is connected to the end of the horizontal pipe 6. One end of the watering pipe 10 is inserted into the horizontal pipe 6 and is slidably and sealed inside the horizontal pipe 6. The other end is equipped with a downward-facing water injection head 19. In this embodiment, to enable the watering pipe 10 to slide within the horizontal pipe 6, a horizontal electric push rod 14 is installed on the horizontal pipe 6. The telescopic end of the horizontal electric push rod 14 is connected to the watering pipe 10. The horizontal electric push rod 14 can drive the watering pipe 10 to slide within the horizontal pipe 6, thereby increasing or decreasing the length of the watering pipe 10 extending out of the horizontal pipe 6 to adapt to different plots of land. Before operation, the telescopic end of the horizontal electric push rod 14 can be extended or retracted according to the characteristics of the plot, so that the water injection head 19 on the horizontal pipe 6 can be positioned just above the well pit 7 on the ridge 1, increasing the effective range.

[0035] The water injection head 19 is positioned downwards, allowing water from it to fall directly into the well pit 7. To control the water level in the water injection head 19, a solenoid valve is connected to it, which controls whether the water injection head 19 is open or closed.

[0036] Meanwhile, to detect whether the water injection head 19 has reached above the well pit 7, a distance measuring module 20 is connected to the water injection head 19. The signal output terminal of the distance measuring module 20 is connected to a processor, and the processor outputs a signal to control the operation of the solenoid valve. During the movement of the vehicle, when it has not encountered the well pit 7, the distance measured by the distance measuring module 20 is relatively short; when it encounters the well pit 7, the distance measured by the distance measuring module 20 suddenly increases. Based on this principle, it is determined whether it has reached above the well pit 7.

[0037] The processor includes a microcontroller, and the ranging module 20 includes an ultrasonic ranging sensor. The ultrasonic ranging sensor transmits the collected distance information to the microcontroller, and the microcontroller outputs a signal to drive the solenoid valve.

[0038] Meanwhile, to introduce water from the pump into the horizontal pipe 6, a flexible hose 16 is connected to the horizontal pipe 6. The flexible hose 16 is connected to the water tank 3 via the pump, so that the pump can draw water from the water tank 3 into the flexible hose 16. To control whether water from the pump enters the flexible hose 16, a valve is also installed on the flexible hose 16. When only atomized water is needed, the valve on the flexible hose 16 can be closed. When only water needs to be injected into the well pit, the valve on the water pipe can be opened. When both atomized water and water need to be injected into the well pit, the valves on both the flexible hose and the water pipe can be opened.

[0039] To accommodate the lifting and lowering of the horizontal pipe 6, a winding frame 17 is provided on the gantry frame 15, and the flexible hose 16 is wound around the winding frame 17. At the same time, the winding frame 17 is rotated by a motor. In this embodiment, the motor drives the rotation of the winding frame 17 through a chain 18.

[0040] During operation, the winding frame 17 rotates clockwise, causing the hose 16 to come down slightly from the winding frame 17 to accommodate the lowering of the horizontal pipe 6; the winding frame 17 rotates counterclockwise, causing the hose 16 to wrap around the winding frame 17 to accommodate the raising of the horizontal pipe 6.

[0041] The working process is as follows: The vehicle moves through the tobacco field driven by the tracks 8. When atomized water spraying is needed, the valve on the water pipe is opened, allowing water from the water pump to enter the spray head 4. At the same time, the spray head 4 rotates under the drive of the spray pipe 5, increasing the spraying range. When water needs to be injected into the well pit 7, the water pump starts, and the vertical electric push rod 9 is adjusted according to the height of the ridge 1 to control the distance between the water injection head 19 and the tobacco ridge 1. At the same time, the horizontal electric push rod 14 is adjusted so that the water injection head 19 is positioned above the well pit 7. Since the well pits 7 are arranged in a row, there is no need to adjust the horizontal electric push rod 14 and the vertical electric push rod 9 during the movement of the vehicle.

[0042] As the vehicle moves, the distance measuring module on the water injection head 19 measures the distance to the area below and transmits the collected distance information to the microcontroller. Based on the distance signal, when the microcontroller determines that it has reached above the well / cellar 7, it 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, thus allowing water to be injected from the water injection head 19 into the well / cellar 7. After the set time is reached, the drive motor of the track 8 resumes operation, the vehicle continues to move, and the solenoid valve closes.

[0043] 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.

[0044] Example 2 differs from Example 1 in that: in this example, an STM32 series microcontroller is used; an HC-SR04 ultrasonic ranging sensor is used; 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.

[0045] 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 ultrasonic sensor and the tobacco plant 21 based on the transmitted and received ultrasonic signals.

[0046] 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 19. Simultaneously, a motor driver chip (model L298N) is connected to the microcontroller to control the drive motor of the track.

[0047] This utility model discloses a device for irrigating tobacco plants, which can simulate rainfall on tobacco plants 2 and inject water into wells and pits 7 in tobacco fields. It is convenient to use and has a wide range of applications, which greatly reduces the management process of tobacco fields, reduces labor costs and labor intensity, and improves economic benefits.
