Description

Technical Field

[0001] This utility model relates to the field of weeding technology, and more specifically, to a handheld flame weeding device. Background Technology

[0002] Weed control is a crucial part of crop cultivation, aiming to control and eliminate weeds that compete with crops for resources, thereby improving crop yield and quality. Current weed control methods primarily involve spraying herbicides or manual weeding. Chemical herbicides can directly kill or cause chronic harm to non-target organisms, severely disrupting the agricultural ecological balance. Manual weeding is labor-intensive, inefficient, and costly. To avoid the damage to the agricultural ecological balance caused by chemical herbicides, a flame-spraying weeding device has emerged that uses flames for weed control.

[0003] In the prior art, Chinese invention patent CN118489661A discloses a liquefied gas flame-type weeding device, including a mounting frame. A drive structure is located on the bottom of the mounting frame, and the drive structure is connected to a walking component. The walking component drives a flame-type weeding mechanism. A base is fixedly connected to the top of the mounting frame, and a liquefied gas tank is placed in a mounting groove on the top surface of the base. A shock-absorbing component is placed between the liquefied gas tank and the base. The liquefied gas tank is connected to the flame-type weeding mechanism. The flame-type weeding mechanism includes a combing component and a swinging flame-type weeding component sequentially arranged on the bottom of the mounting frame. The liquefied gas tank is connected to the swinging flame-type weeding component. The walking component is driven by the combing component, and the walking component is driven by a linkage component, which is driven by the swinging flame-type weeding component. This weeding device can achieve multi-angle flame-type weeding, but due to its large size and high cost, it is not suitable for small planting areas or complex terrain, and it is inconvenient to carry.

[0004] Therefore, a new solution is needed to address the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: A handheld flame weeding device, such as Figures 1-5 As shown, it includes a circular tube 1, with a housing 2 installed at one end of the circular tube 1. The housing 2 is a hollow cylindrical structure with an inner cavity. Multiple air inlets 3 are opened on the outer surface of one end of the housing 2, which are connected to the inner cavity of the housing 2. That is, the inner cavity of the housing 2 is connected to the outside through the air inlets 3, and outside air can flow into the inner cavity of the housing 2 through the air inlets 3. A fire-gathering hood 4 is installed at the other end of the housing 2. A fan 5 is installed in the inner cavity of the housing 2, and the fan 5 is located at the air inlet 3 of the housing 2. When the fan 5 is running, outside air first flows into the inner cavity of the housing 2 through the air inlet 3, and then flows to the fire-gathering hood 4, and is discharged through the fire-gathering hood 4.

[0025] Furthermore, such as Figure 2As described above, an installation plate 6 is installed inside the housing 2 between the fan 5 and the flame hood 4. An ignition needle 7 and a nozzle 8 are respectively installed on the installation plate 6. The ignition needle 7 is located on the side of the nozzle 8. The nozzle 8 is a spray nozzle used to atomize and spray out fuel oil. The ignition needle 7 is used to generate an electric spark and use the electric spark to ignite the atomized fuel oil, thereby generating a flame.

[0026] An oil pipe 9 is fixedly installed on the upper surface of the circular tube 1. One end of the oil pipe 9 extends along the length of the circular tube 1 to the housing 2, and the other end of the oil pipe 9 penetrates into the inner cavity of the housing 2 and connects to a nozzle 8 inside the inner cavity of the housing 2. A connector 10 is installed at the other end of the oil pipe 9, and a shut-off valve 20 is installed on the connector 10. The connector 10 is used to connect a hose 18, and through the hose 18, it connects to a fuel tank 16 containing fuel oil. The shut-off valve 20 is used to control the opening and closing of the connector 10. When the shut-off valve 20 is open, the connector 10 is open, and fuel oil flows through the connector 10 to the oil pipe 9. When the shut-off valve 20 is closed, the connector 10 is closed, and fuel oil cannot flow through the connector 10. In use, fuel oil is introduced into the oil pipe 9 through the connector 10 and flows through the oil pipe 9 to the nozzle 8, where the nozzle 8 atomizes and sprays the fuel oil. Preferably, a protective cover 19 is provided for the portion of the oil pipe 9 located in the housing 2 to protect this portion of the oil pipe 9 from damage by collision or impact.

[0027] A controller 11 is mounted on the lower surface of the circular tube 1. The controller 11 is electrically connected to the ignition needle 7 and the fan 5. By setting the controller 11, the controller 11 integrates the control of the ignition needle 7 and the fan 5, so as to facilitate the control of the ignition needle 7 and the fan 5.

[0028] Furthermore, such as Figure 4 As shown, the controller 11 includes a housing 1101 mounted on the lower surface of the circular tube 1. An igniter 1102 and a battery 1103 are installed inside the housing 1101. A fan speed control knob 1104, an ignition switch 1105, a power switch 1106, and a charging interface 1107 are respectively installed on the housing 1101. The battery 1103 is electrically connected to the igniter 1102, the fan speed control knob 1104, the ignition switch 1105, the power switch 1106, and the charging interface 1107.

[0029] Among them, battery 1103 is a rechargeable battery used for power supply. Battery 1103 is connected to charging interface 1107, and the charger can charge battery 1103 by plugging into charging interface 1107; ignition switch 1105 is electrically connected to ignition needle 7, and igniter 1102 is a high-voltage igniter that can be purchased directly from the market. Its function is to convert the low voltage of battery 1103 into high voltage pulses. Ignition needle 7 generates an electric spark after receiving the high voltage pulses; fan speed control knob 1104 is electrically connected to fan 5 and is used to adjust the fan speed of fan 5. When the fan speed control knob is turned to the maximum position, the fan speed of fan 5 is the maximum. When the fan speed control knob is turned to the minimum position, the fan speed of fan 5 is zero, that is, fan 5 is off; power switch 1106 is used to turn the weeding device on and off.

[0030] Preferably, a time delay device 1108 is also installed inside the housing 1101, which is electrically connected to the fan speed control knob 1104. When the fan speed control knob 1104 is turned to the minimum position to turn off the fan 5, the time delay device 1108 can be used to allow the fan 5 to continue running for a period of time before turning off, so as to blow air to cool the inner cavity of the housing 2 and the components inside the inner cavity of the housing 2.

[0031] Furthermore, such as Figure 3 As shown, the mounting plate 6 includes a mounting portion 601 and a connecting portion 602. The mounting portion 601 has a disc-shaped structure, and its diameter is smaller than the inner diameter of the housing 2. Four connecting portions 602 are provided, which are evenly distributed along the outer periphery of the mounting portion 601. One end of the connecting portion 602 is fixedly connected to the mounting portion 601, and the other end is fixedly connected to the inner wall of the housing 2. That is, the mounting plate 6 is installed in the inner cavity of the housing 2 through the connecting portions 602. Since the diameter of the mounting portion 601 is smaller than the inner diameter of the housing 2, a gap 603 is formed between its edge and the inner wall of the housing 2. Air flowing into the inner cavity of the housing 2 through the air inlet 3 is driven by the fan 5, passes through the gap 603, and flows to the flame-gathering hood 4, and is discharged through the flame-gathering hood 4.

[0032] Furthermore, such as Figure 2 As shown, a flame distributor 12 is installed inside the cavity of the housing 2 at the flame distribution shroud 4. The flame distributor 12 includes a star-shaped flame distribution fin 1201 and a flame distribution plate 1202 with through holes, which is located between the flame distribution fin 1201 and the flame distribution shroud 4. By setting the flame distributor 12, the flame is dispersed to achieve uniform combustion.

[0033] Furthermore, such as Figure 1 As shown, mounting bases 13 are installed at both ends of the round tube 1. The mounting bases 13 are clamp-type, and a shoulder strap 14 is connected between the two mounting bases 13. A handle 15 is installed on the round tube 1. The shoulder strap 14 and handle 15 are provided to facilitate hand-holding of the weeding device, and the shoulder strap 14 is also used for easy carrying.

[0034] When using, such as Figure 5 As shown, the connector 10 of the weeding device is connected to a hose 18, which in turn connects to a fuel tank 16. The fuel tank 16 stores fuel oil, which can be white oil or liquid wax. A fuel pump 17 is installed at the bottom of the fuel tank 16, meaning the outlet of the fuel tank 16 is connected to the input of the fuel pump 17. The output of the fuel pump 17 is connected to the hose 18. The fuel tank 16 is equipped with an inlet and a vent valve for adjusting the air pressure inside the fuel tank 16. Then, the operator carries the fuel tank 16 on their back and uses their shoulder... The operator hangs the weeding device on their shoulder with belt 14; then, the oil pump 17 is started, the shut-off valve 20 is opened, and the fuel oil in the oil tank 16 is pumped by the oil pump 17 to the oil pipe 9, which flows to the nozzle 8. The nozzle 8 atomizes the fuel oil and sprays it out. At the same time, the power switch 1106, the ignition switch 1105 and the fan speed control knob 1104 are turned on, and the electric spark generated by the ignition needle 7 is used to ignite the atomized fuel oil; then, the operator holds the handle 15 and aims it at the grass to burn it.
