Description

Technical Field

[0001] This invention belongs to the field of tobacco plant protection technology, and in particular relates to an integrated watering vehicle for tobacco plant protection in the industry. Background Technology

[0002] During the growth process of tobacco seedlings, water needs to be injected into the seedling holes in the early stage of growth. The current watering method is hand-held watering, which is inefficient and labor-intensive. In order to achieve mechanized operation, the existing technology, such as the patent application with authorization number: CN222485644U, discloses a seedling watering tool for flue-cured tobacco planting in mountainous areas, including: a water tank; a water cavity set inside the water tank; fixing blocks are fixedly installed on both sides of the surface of the water tank; mounting plates are fixedly installed on the other two sides of the surface of the water tank; a sliding rod is fixedly installed on one side of the surface of the mounting plate; a spring is sleeved on the outer surface of the sliding rod; a moving device is sleeved on one side of the outer surface of the sliding rod; and a watering and seedling removal device is set on one side of the moving device. This utility model provides a tool for purging and watering tobacco seedlings in mountainous areas. By pressing down on the lever, the watering and purging device pierces the film downwards and waters the tobacco seedlings. Then, by releasing the lever, the spring's restoring force pushes the moving device upwards to return to its original position, ready for the next use. This device has a simple structure, is highly practical, does not use electrical control, and can achieve the purging and watering action by manual operation alone. The tool can work outdoors for a long time and is highly practical.

[0003] This device can often only be used in the early stages of tobacco seedling growth, and it cannot be used for subsequent plant protection.

[0004] In existing technologies, there are also methods of injecting water into the seedling holes. The current method involves directly injecting water into the seedling holes, and the water falls directly onto the seedlings in the early stages of growth, which can easily damage the seedlings.

[0005] Plant protection of tobacco leaves is an important part of ensuring the healthy growth of tobacco seedlings during the tobacco planting process. Currently, plant protection methods include manual plant protection and mechanical plant protection.

[0006] Manual plant protection methods are inefficient and labor-intensive;

[0007] Mechanical plant protection methods, such as the application with publication number CN216567886U, disclose an insecticidal spraying device for tobacco plant protection, including a base plate, a box fixedly connected to the upper surface of the base plate, a water inlet pipe fixedly connected to the upper surface of the box, a battery fixedly connected to the right side of the base plate, a telescopic pipe fixedly connected to the left side of the box, a connecting pipe fixedly connected to the output end of the telescopic pipe, and nozzles fixedly connected to both output ends of the connecting pipe. A threaded pipe is fixedly connected to the upper surface of the base plate. This utility model, through the cooperation of the threaded pipe and the threaded rod, allows the threaded rod to move up and down, and the threaded rod can control the movement of the support rod, allowing the connecting pipe to adjust the height of the nozzles. In addition, with the help of a push plate and rollers, the device can be moved by the operator, thus solving the problem that the tobacco plants are relatively tall and require operators to hold the nozzles high for a long time, resulting in high labor intensity for the operators. The connecting tube is used to spray plant protection liquid into the tobacco leaves. Although this connecting tube method can adjust the height of the nozzle, the adjustment is complicated and the height adjustment is limited. It cannot select the appropriate height according to the different growth stages of the tobacco plants, making it inflexible in use. Summary of the Invention

[0008] The present invention aims to provide an integrated tobacco plant protection and irrigation vehicle with simple structure and good performance.

[0009] To solve the above-mentioned technical problems, the present invention provides the following technical solution: an integrated tobacco plant protection and irrigation vehicle, including a vehicle body, a water tank, an irrigation pipe and a plant protection frame located above the irrigation pipe;

[0010] Water from the tank enters the watering pipes and plant protection racks;

[0011] The plant protection frame is equipped with a first atomizing nozzle, which is set at an angle downwards;

[0012] The watering pipe has water inlets located on both sides of the vehicle body at both ends, with the water inlets facing downwards. A cone-shaped water distribution block is located in the middle of the water inlet, and the water distribution block is fixedly connected to the watering pipe.

[0013] A distance sensor is installed on the watering nozzle. The distance sensor collects the distance signal between the watering nozzle and the ground and transmits the collected distance signal to the controller. The controller then controls the water to come out of the watering nozzle.

[0014] A water pump is connected to the water tank, and the outlet of the water pump is connected to the watering pipe and the plant protection frame. The controller outputs a signal to control the operation of the water pump.

[0015] The plant protection frame consists of a longitudinal tube and multiple horizontal tubes connected to the longitudinal tube, with each horizontal tube evenly distributed along the height direction of the longitudinal tube.

[0016] The first atomizing nozzle is installed on the longitudinal pipe, and the first atomizing nozzle is evenly distributed along the height direction of the longitudinal pipe.

[0017] The top of the plant protection rack is equipped with a plant protection pipe, which is connected to the longitudinal pipe. The length of the plant protection pipe is greater than the length of the horizontal pipe. A second atomizing nozzle is installed at the end of the plant protection pipe, and the second atomizing nozzle is set downward.

[0018] The vehicle is equipped with casters at the bottom.

[0019] The watering pipe includes a T-shaped main pipe and connecting pipes. One end of the T-shaped main pipe is connected to the water pump; the other two ends are connected to two connecting pipes respectively. The other two ends of the T-shaped main pipe are slidably sealed to the two connecting pipes, and the watering nozzles are located on the connecting pipes. Each of the first atomizing nozzles is equipped with a switch.

[0020] Through the above technical solutions, the technical effects of this invention are as follows: 1. This utility model discloses an integrated tobacco plant protection and irrigation vehicle that moves within the row. The vehicle body is small and flexible, enabling targeted irrigation of tobacco seedling holes and plant protection for subsequent growth stages of tobacco seedlings. It has more complete functions, is convenient to use, and has high stability. 2. The water distribution blocks can protect the tobacco seedlings, preventing water from directly hitting the seedlings and causing damage in the early stages of growth. 3. The irrigation pipe and plant protection frame are installed on the vehicle body simultaneously, providing more functions. 4. The distance sensor can detect the information of the tobacco seedling holes. When the distance sensor reaches the seedling hole, the first electromagnetic switch valve opens, allowing water from the pump to enter the seedling hole for targeted irrigation. 5. The plant protection frame can select a suitable first atomizing nozzle based on the height of the tobacco seedlings, and work in conjunction with a second atomizing nozzle to flexibly achieve plant protection for the tobacco plants. 6. The plant protection pipe can achieve directional spraying of tobacco plants in the later stages of growth, improving the plant protection effect. Attached Figure Description

[0026] Example 1, as Figures 1-4 As shown, this utility model describes an integrated tobacco plant protection and irrigation vehicle. The entire vehicle body 1 moves between two rows 4, eliminating the need for the vehicle body 1 to cross rows 4 and reducing its overall height. Compared to the current gantry-type structure, the vehicle body 1 offers greater stability. The integrated vehicle includes a vehicle body 1, on which a water tank 9, an irrigation pipe 8, and a plant protection frame 6 located above the irrigation pipe 8 are mounted. The bottom of the vehicle body 1 is equipped with casters 2, which allow the vehicle body 1 to move between two rows 4. During setup, the water tank 9 and irrigation pipe 8 are installed sequentially from front to back on the vehicle body 1. A battery is located in front of the water tank 9 on the vehicle body 1, ensuring normal power supply to the vehicle body 1.

[0027] The vehicle body 1 is equipped with a water tank 9. When in use, water, fertilizer or medicine can be introduced into the water tank 9 as needed to achieve watering, fertilization or spraying.

[0028] A water pump is connected to the water tank 9, and the outlet of the water pump is connected to the irrigation pipe 8. The water pump draws water from the water tank 9 into the irrigation pipe 8, causing the water to flow out from the irrigation pipe 8. The irrigation pipe 8 includes a T-shaped main pipe 16 and connecting pipes 17. One end of the T-shaped main pipe 16 is connected to the outlet of the water pump, and the other two ends of the T-shaped main pipe 16 are slidably connected to two connecting pipes 17. The connecting pipes 17 are slidably sealed on the T-shaped main pipe 16, so the connecting pipes 17 can be manually moved as needed to lengthen or shorten their extension, thereby adjusting according to the field conditions. As a variation of this embodiment, in order to limit the sliding of the connecting pipe 17, two electric telescopic rods 18 can be used. The two electric telescopic rods 18 are connected to the tee main pipe 16. When the row is relatively wide and the distance between the two ridges 4 is relatively far, the electric telescopic rods 18 are used to make the length of the connecting pipe 17 extending from the tee main pipe 16 longer, so that the watering nozzles 14 on the two connecting pipes 17 correspond to the seedling holes 3 on one ridge 4 respectively.

[0029] To facilitate control over whether water flows into the three-way main pipe 16, a first solenoid valve is connected to the three-way main pipe 16. The solenoid valve used is a mature, existing technology. When the first solenoid valve is in the open position, water from the pump can enter the three-way main pipe 16 through the first solenoid valve, and then enter the connecting pipe 17. When the first solenoid valve is in the closed position, water from the pump cannot enter the connecting pipe 17.

[0030] The end of the connecting pipe 17 is provided with a water inlet 14, which is set downwards so that water is injected downwards into the tobacco seedling hole 3. A shut-off valve is provided on the connecting pipe 17. When water is not needed to flow from the water inlet 14, the shut-off valve can be closed, allowing water to flow out of the water inlet 14; when water is needed to flow from the water inlet 14, the shut-off valve can be opened, allowing water to flow out of the water inlet 14.

[0031] To prevent the water from damaging the tobacco leaves, a cone-shaped water distribution block 15 is provided in the middle of the watering nozzle 14, and the water distribution block 15 is fixedly connected to the connecting pipe 17. The larger end of the water distribution block 15 is at the bottom and the smaller end is at the top, so that when in use, the water flows out of the watering nozzle 14 and onto the water distribution block 15, and is dispersed by the water distribution block 15. In this way, the water will not fall into the center of the tobacco seedlings 5, but will be dispersed, thereby protecting the tobacco seedlings 5.

[0032] In order to collect the location information of the tobacco seedling hole 3, a distance sensor 13 is installed at the end of the connecting pipe 17 near the water outlet 14. The distance sensor 13 is set downwards, so that the distance sensor 13 collects the location information between the water outlet 14 and the field. When the location information is greater than the threshold, it means that the distance sensor 13 is collecting the distance between the water outlet 14 and the tobacco seedling hole 3, and thus it is determined that this is the tobacco seedling hole 3.

[0033] A controller is connected to the distance sensor 13, so that the distance sensor 13 transmits the collected distance information to the controller, and the controller outputs a signal to control the operation of the first switch solenoid valve.

[0034] The controller receives distance information from distance sensor 13 and compares it with a threshold. When the distance information is greater than the threshold, it determines that the distance has reached above the tobacco seedling hole 3. At this time, the controller outputs a signal to make the first electromagnetic switch valve work. Water in water tank 9 enters the connecting pipe 17 through the three-way main pipe 16 under the action of the water pump, and then enters the watering outlet 14 through the connecting pipe 17. Water flows out from the watering outlet 14 and flows onto the water distribution block 15. Under the action of the water distribution block 15, the water spreads out instead of falling directly onto the tobacco seedling 5.

[0035] In this embodiment, the watering pipe 8 waters the tobacco seedlings 5; while the plant protection frame 6 above the watering pipe 8 protects the tobacco seedlings 5.

[0036] The plant protection frame 6 includes a longitudinal tube 10 and multiple horizontal tubes 11 connected to the longitudinal tube 10, with each horizontal tube 11 evenly distributed along the height direction of the longitudinal tube 10.

[0037] A water pipe is connected to the bottom longitudinal pipe 10, which is also connected to the outlet of the water pump, so that the water pump outlet enters the longitudinal pipe 10 through the water pipe. To facilitate control of whether water enters the water pipe, a second solenoid valve is connected to the water pipe. When the second solenoid valve is in the open position, water from the pump can enter the water pipe through the second solenoid valve. When the second solenoid valve is in the closed position, water from the pump cannot enter the water pipe through the second solenoid valve.

[0038] Multiple first atomizing nozzles 19 are arranged sequentially from bottom to top on the longitudinal tube 10. The first atomizing nozzles 19 are angled downwards, and each nozzle has a different height to accommodate different stages of tobacco seedling growth 5. A switch is installed on each first atomizing nozzle 19. When the switch is off, the nozzle 19 cannot spray atomized water; when the switch is on, the nozzle 19 can spray atomized water, making it convenient and flexible to use. Atomizing nozzles with switches are mature existing technology; this embodiment directly uses commercially available products without any modifications.

[0039] To further ensure the effectiveness of use, a plant protection pipe 7 is provided at the top of the plant protection frame 6, and the plant protection pipe 7 is connected to the longitudinal pipe 10; the length of the plant protection pipe 7 is greater than the length of the horizontal pipe 11, and a second atomizing nozzle 12 is installed at the end of the plant protection pipe 7, with the second atomizing nozzle 12 facing downward.

[0040] The second atomizing nozzle 12 is located at the top of the plant protection frame 6. When the tobacco seedlings 5 ​​reach the late stage of growth, the second atomizing nozzle 12 can still spray pesticides on the tobacco seedlings 5.

[0041] As a supplement to this embodiment, for ease of control, a switch panel is provided on the vehicle body 1. The switch panel is equipped with an agricultural protection switch and a main switch. The agricultural protection switch controls whether the second electromagnetic switch is energized; the main switch controls whether the water pump is energized. Pressing the main switch energizes the water pump; pressing the agricultural protection switch energizes the second electromagnetic valve and puts it in the open state. In this way, the agricultural protection switch can be connected in series between the power supply and the coil of the second electromagnetic valve. Thus, pressing the agricultural protection switch energizes whether the coil of the second electromagnetic valve is energized. When energized, the second electromagnetic valve is in the open state; when de-energized, the second electromagnetic valve is in the closed state.

[0042] The working process is as follows: the user adds water into the water tank 9; if only watering is needed, then only water needs to be added; if fertilizer or pesticide needs to be added, then water or pesticide needs to be added into the water tank 9 accordingly.

[0043] In the early stages of tobacco seedling growth 5, the shut-off valve on the connecting pipe 17 needs to be opened to allow water to enter the watering inlet 14 from the connecting pipe 17. At this time, the switches on the first atomizing nozzle 19 and the second atomizing nozzle 12 are both closed. As the vehicle body 1 moves, the distance sensor 13 collects distance information and transmits the collected distance information to the processor. When the processor determines that it has encountered the tobacco seedling hole 3, it outputs a signal to open the first electromagnetic switch valve. The water pump draws water from the water tank 9 into the three-way main pipe 16. The water flows through the three-way main pipe 16 into the connecting pipe 17 and finally flows downward from the watering inlet 14 at the end of the connecting pipe 17 into the tobacco seedling hole 3. During the flow into the tobacco seedling hole 3, the water distribution block 15 prevents water from falling onto the tobacco seedling 5, thereby protecting the tobacco seedling 5.

[0044] When plant protection is required, the tobacco seedlings 5 ​​have already reached a certain height. Close the shut-off valve on the connecting pipe 17, press the plant protection switch, and open the second electromagnetic switch valve on the plant protection frame 6. Simultaneously, move the connecting pipe 17 towards the three-way main pipe 16, ensuring that the connecting pipe 17 does not touch the tobacco seedlings 5 ​​during the movement of the vehicle body 1. Based on the height of the tobacco seedlings 5, select the appropriate height for the first atomizing nozzle 19 and turn on its switch. The selection method is to turn on the switch of the first atomizing nozzle 19 approximately 200mm above the tobacco seedlings 5. Simultaneously, turn on the switch of the second atomizing nozzle 12. The water pump operates, and during the movement of the vehicle body 1, the water pump draws water from the water tank 9 into the water pipe connected to the longitudinal pipe 10. The water enters the longitudinal pipe 10 through the water pipe and flows out from the first atomizing nozzle 19 and the second atomizing nozzle 12, which are now open. The atomized water is sprayed onto the tobacco seedlings 5, achieving plant protection for the tobacco seedlings 5.

[0045] Example 2 differs from Example 1 in that: in this example, a motor is connected to the movable wheel 2, and the battery on the vehicle body 1 powers the motor and water pump. The motor drives the movable wheel 2. During operation, the distance sensor 13 collects distance signals and transmits them to the controller. The controller outputs a signal to control the operation of the first electromagnetic switch valve and the motor. Thus, when the water inlet 14 reaches above the tobacco seedling hole 3, the controller outputs a signal to make the water pump work, while simultaneously stopping the motor for a set time, thereby releasing a set amount of water into the tobacco seedling hole 3.

[0046] Example 3 differs from Example 2 in that the controller used in this example is an STM32F103 microcontroller. The distance sensor 13 used is a photoelectric sensor (model E3AS-HL, manufacturer: Omron), and its signal output is connected to the microcontroller's I / O pin. The microcontroller's output signal drives the motor by connecting a motor driver chip (L298N) to the microcontroller's signal output. Simultaneously, a solenoid valve drive circuit is connected to the microcontroller's signal output, which drives the first solenoid valve.

[0047] The solenoid valve drive circuit used in this embodiment is a mature existing technology. In principle, existing technology can be used directly. This is for further description of the technical solution. The solenoid valve drive circuit includes a current-limiting resistor, a transistor, and a freewheeling diode. The microcontroller's I / O port is connected to the base of the transistor through the current-limiting resistor, and the transistor's emitter is grounded. The collector of the transistor is connected to one end of the solenoid valve coil, and the other end of the solenoid valve coil is connected to the positive terminal of the power supply. The freewheeling diode is connected in reverse parallel across the two ends of the solenoid valve coil.

[0048] Distance sensor 13 collects distance information and transmits it to the microcontroller. The microcontroller compares the received information with a threshold. When it determines that the distance has reached above the seedling hole 3, the microcontroller outputs a signal to the motor driver chip to stop the motor. At the same time, the microcontroller outputs a signal to the solenoid valve drive circuit, causing the first solenoid switch to open for a set time. At this time, the vehicle body 1 stops, and water from the water pump enters the three-way main pipe 16, then enters the connecting pipe 17, and flows out from the water outlet 14 at the end of the connecting pipe 17 into the seedling hole 3. After the set time is reached, the microcontroller outputs a signal to the motor driver chip to rotate the motor. At the same time, the microcontroller outputs a signal to the solenoid valve drive circuit to close the first solenoid valve.

[0049] To ensure the normal operation of the water pump, an overflow valve is connected to the water pump outlet. When the pressure at the water pump outlet is higher than the set pressure of the overflow valve, the water at the water pump outlet will flow back to the water tank 9 through the overflow valve.

[0050] This utility model discloses an integrated watering and protection vehicle for tobacco plants within a row. The vehicle body 1 moves within the row. The vehicle body 1 is small and flexible, enabling it to water the tobacco seedling holes 3 at specific points, as well as to provide plant protection for the tobacco seedlings 5 ​​during their subsequent growth stages. It has more complete functions, is easy to use, and has high stability.
