Description

Technical Field

[0001] This utility model belongs to the field of tobacco seedling irrigation technology, and in particular relates to a root irrigation device for topdressing tobacco seedlings. Background Technology

[0002] Root drenching is a plant care technique that involves applying a solution containing fertilizers, pesticides, or other beneficial substances directly to the soil around the plant roots through irrigation. The effects of root drenching include: 1. Nutrient replenishment: It precisely delivers fertilizer to the plant roots, allowing for more effective nutrient absorption and promoting growth. For example, during the flowering and fruiting period of fruit trees, applying phosphorus and potassium-containing fertilizers through root drenching can improve fruit quality and yield. 2. Pest and disease control: Diluted pesticides applied through root drenching can kill pathogens and pests in the roots. For example, using carbendazim to control root rot and phoxim to control underground pests. 3. Promoting root growth: For transplanted plants or flowers that are difficult to root, using a solution containing rooting agents for root drenching can stimulate root growth and improve survival rates.

[0003] The method for root irrigation is as follows: Dig a circular or radial trench around the plant roots, slowly pour the solution into the trench, and then cover with soil. Alternatively, the solution can be poured directly onto the soil around the roots, but ensure that the solution fully penetrates the roots.

[0004] Application CN222622018U discloses a root irrigation device for plant disease and pest control, belonging to the field of plant disease and pest control technology. It mainly includes: a main body, an application structure, a grip, a battery, and a storage tank. The grip is installed at one end of the main body, and a battery is embedded between the grip and the main body. The storage tank and the application structure are installed inside the main body. The application structure consists of an application component, a lateral adjustment structure, and a push-pull component. Some components of the application mechanism are connected to the storage tank, while others protrude outside the main body. This invention features an adjustable application structure and a pre-filled structure, effectively improving application accuracy and efficiency. This invention is mainly used for root application of pesticides to food pests and diseases. However, this root irrigation device requires handheld use, and its tip points directly downwards, which can easily damage tobacco leaves during the downward movement, affecting the growth of tobacco seedlings.

[0005] How to provide a root irrigation device that can both reduce labor intensity and improve the root irrigation effect is an urgent problem to be solved. Utility Model Content

[0006] The present invention aims to provide a root irrigation device for topdressing tobacco seedlings that is simple in structure and effective in use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a root irrigation device for topdressing tobacco seedlings, including a water tank, a water pump, an electric push rod, and a rod with a hollow cavity inside. The water tank is connected to the hollow cavity through the water pump. The rod is inclined downwards and the electric push rod drives the rod to move. The top of the rod is provided with a pointed tip, and the rod is provided with a water outlet hole communicating with the hollow cavity.

[0008] It also includes the vehicle body, with the electric push rod mounted on the vehicle body and the rod connected to the telescopic end of the electric push rod; the water tank and water pump are both located on the vehicle body.

[0009] There are at least two water outlets, and each water outlet is evenly distributed along the circumference of the rod.

[0010] A contact rod is connected to the rear of the rod, perpendicular to the rod body.

[0011] A micro switch is installed on the contact rod, which controls the start of the water pump.

[0012] The vehicle body is equipped with an ultrasonic ranging module, which is oriented towards the ridge and is higher than the ridge. The signal output terminal of the ultrasonic ranging module is connected to a processor.

[0013] The micro switch is connected to the signal input terminal of the processor, and the processor outputs a signal to control the operation of the electric push rod and the water pump.

[0014] Through the above technical solutions, the technical effects of this utility model are as follows: 1. This utility model discloses a root irrigation device for topdressing tobacco seedlings. When encountering tobacco seedlings, the tip of the pole is inserted into the soil, and the water pump draws the solution from the water tank into the hollow cavity of the pole. The solution comes out from the water outlet and flows to the roots of the tobacco seedlings to achieve root irrigation. The structure is simple, convenient to implement, reduces labor costs, and greatly improves root irrigation efficiency. At the same time, it can effectively control the insertion depth of the pole, thereby controlling the root irrigation depth and effectively controlling the root irrigation effect; 2. The electric push rod can drive the pole to move obliquely downward, so that the tip is inserted into the soil to irrigate the roots of the tobacco seedlings; 3. The water outlet allows the solution to come out from inside the pole and enter the tip; 4. The contact rod can limit the depth of the tip insertion into the pole to prevent the pole from being inserted too deeply. Attached Figure Description

[0019] Tobacco seedling-1, ridge-2, pole-3, vehicle body-4, water tank-5, electric push rod-6, mounting bracket-7, mounting hole-8, tip-9, contact rod-10, water outlet-11. Detailed Implementation

[0020] like Figure 1 As shown, the root irrigation device for topdressing tobacco seedlings includes a vehicle body 4, which can move between rows 2 of tobacco seedlings 1. A water tank 5 is installed on the vehicle body 4, containing a prepared solution. In this embodiment, the solution used for root irrigation is a mature existing technology, and this embodiment does not involve any improvement to this part. Meanwhile, to facilitate the extraction of water from the water tank 5, a water pump is installed on the vehicle body 4, which can pump the water out of the water tank 5.

[0021] In addition, for the purpose of root irrigation, two rods 3 are provided on the vehicle body 4. Both rods 3 are inclined downwards and are positioned opposite each other. Since the vehicle body 4 is located between the ridges, the two rods 3 are located on both sides of the ridge. Because the tobacco seedlings 1 are often planted on the ridge 2 during the planting process, the rods 3 can be inserted into the ridge 2 when they move downwards, thereby getting closer to the roots of the tobacco seedlings 1. By setting up two rods 3, the roots of the tobacco seedlings 1 can be more fully contacted with the solution.

[0022] The structure of the rod 3 is described as follows: The rod 3 has an internal hollow cavity, and the water tank 5 is connected to the hollow cavity of the rod 3 via a water pump. Additionally, the rod 3 has a water outlet 11, which communicates with the hollow cavity. In this embodiment, there are at least two water outlets 11, evenly distributed along the circumference of the rod 3. Water from the water pump enters the hollow cavity and finally exits through the water outlet 11. To facilitate the delivery of water into the soil near the roots of the tobacco seedlings 1, a tip 9 is provided at the top of the rod 3. As the rod 3 moves, the tip 9 can drive the rod 3 into the soil. The water outlet 11 is located behind the tip 9.

[0023] The stem 3 moves diagonally downwards, and the tip 9 is inserted into the soil. Water comes out from the water outlet 11 and flows between the tip 9 and the soil, immersing the roots of the tobacco seedling 1 in water.

[0024] During implementation, in order to facilitate the downward movement of the pole 3, an electric push rod 6 is provided on the vehicle body 4. The electric push rod 6 is installed on the vehicle body 4, and the pole 3 is connected to the moving end of the electric push rod 6. The electric push rod 6 is set to tilt downward, so that the electric push rod 6 can drive the pole 3 to tilt downward toward the root of the tobacco seedling 1.

[0025] In this embodiment, to facilitate control of the insertion depth of the rod 3 into the soil, a contact rod 10 is connected to the rear of the rod 3, perpendicular to the rod 3. A micro switch U2 is provided on the contact rod 10; in this embodiment, the micro switch U2 controls the activation of the water pump.

[0026] In this embodiment, to control the movement of the electric push rod 6, an ultrasonic ranging module U3 is installed on the vehicle body 4. The ultrasonic ranging module U3 is horizontally positioned and facing the ridge, with its height higher than the ridge, so it can be used to measure the distance between itself and the tobacco seedlings on the ridge. The signal output terminal of the ultrasonic ranging module U3 is connected to a processor. Simultaneously, a micro switch U2 is connected to the signal input terminal of the processor, and the processor outputs a signal to control the operation of the electric push rod 6 and the water pump.

[0027] The processor includes the STM32 microcontroller U1.

[0028] The ultrasonic ranging module U3 collects distance information and transmits it to the microcontroller U1. The microcontroller U1 determines whether the received signal is a tobacco seedling 1. This method of determining whether the tobacco seedling 1 is a tobacco seedling 1 based on the received distance information is a mature existing technology. The main reason is that since the tobacco seedling 1 is arranged in a row along the ridge 2, when the vehicle body 4 travels, the distance value collected by the ultrasonic ranging module U3 will decrease when it encounters a tobacco seedling 1. When it has not moved to the position of the tobacco seedling 1, the distance value will be relatively large. Based on this change, it is determined whether the pole 3 on the vehicle body 4 has moved to the position of the tobacco seedling 1. This embodiment does not involve any improvement to this part; it is sufficient to use the existing technology.

[0029] Microswitch U2 is connected to the signal input terminal of microcontroller U1, thereby transmitting the switching signal from microswitch U2 to microcontroller U1. Microcontroller U1 connects to electric actuator 6 and water pump through a drive circuit, thereby controlling the operation of electric actuator 6 and water pump. In this embodiment, the microcontroller U1 output signal to control the operation of electric actuator 6 and water pump is a mature existing technology, and this embodiment does not involve any improvement to this part.

[0030] The vehicle body 4 moves the rod body 3 in the tobacco seedling field 1. The ultrasonic ranging module U3 collects the distance information between itself and the tobacco seedling 1 and transmits the collected information to the microcontroller U1. When the microcontroller U1 determines that it has reached the position of the tobacco seedling 1, the microcontroller U1 outputs a signal to drive the electric push rod 6 to move. After the micro switch U2 contacts the ground, the micro switch U2 sends a signal to the microcontroller U1. The microcontroller U1 outputs a signal to stop the electric push rod 6 from moving. At the same time, the water pump works, sucking water from the water tank 5 into the hollow cavity and out of the water outlet 11, flowing into the roots of the tobacco seedling 1.

[0031] The specific connections between the micro switch U2, the ultrasonic ranging module U3, the water pump and the electric push rod 6 and the microcontroller U1 are then defined.

[0032] In this circuit, one end of the microswitch U2 is connected to the signal input terminal of the microcontroller U1, and the other end of the microswitch U2 is grounded. Simultaneously, the signal input terminal of the microcontroller U1 is connected to a DC power supply via a pull-up resistor. Therefore, the microswitch U2 can transmit the switching signal to the microcontroller U1.

[0033] For the ultrasonic ranging module U3, the ultrasonic ranging module U3 with model number HC-SR04 is selected. The power supply pin of the ultrasonic ranging module U3 is connected to the power supply pin of the microcontroller U1, and the ground pin of the ultrasonic ranging module U3 is connected to the ground pin of the microcontroller U1.

[0034] Meanwhile, the Trig trigger pin of the ultrasonic ranging module U3 is connected to one GPIO pin of the microcontroller U1, and the Echo receiver pin of the ultrasonic ranging module U3 is connected to another GPIO pin of the microcontroller U1, so as to determine the distance between the ultrasonic sensor and the seedling 1 based on the transmitted and received ultrasonic signals.

[0035] The water pump and electric actuator 6 can be driven by the microcontroller U1 using the L298N motor driver chip U4. Connect the motor driver chip U4 to the signal output terminal of the microcontroller U1, and the water pump and electric actuator 6 can be driven by the motor driver chip U4.

[0036] In this embodiment, the connection between the micro switch U2, the ultrasonic ranging module U3, the motor drive chip U4 and the microcontroller U1 is a mature existing technology. The above is just an example of one implementation method.

[0037] Example 2 differs from Example 1 in that a mounting bracket 7 is installed on the vehicle body 4, and the electric push rod 6 is mounted on the mounting bracket 7. For easy adjustment, mounting holes 8 are arranged sequentially along the height direction on the mounting bracket 7. The electric push rod 6 has a bolt rod, which is inserted into the mounting hole 8 and then secured with a nut. By providing the mounting holes 8, the installation height of the electric push rod 6 can be adjusted, making this device suitable for ridges 2 of different heights and expanding its application range.

[0038] This utility model discloses a root irrigation device for topdressing tobacco seedlings. When encountering tobacco seedlings, the tip of the pole is inserted into the soil, and a water pump draws the solution from the water tank into the hollow cavity of the pole. The solution comes out from the water outlet and flows to the roots of the tobacco seedlings to achieve root irrigation. The structure is simple and easy to implement, reducing labor costs and greatly improving root irrigation efficiency. At the same time, the insertion depth of the pole can be effectively controlled, thereby controlling the root irrigation depth and effectively controlling the root irrigation effect.
