Description

Technical Field

[0001] This utility model belongs to the field of agricultural machinery and equipment weeding technology, specifically relating to a fuel atomization flame weeding device. Background Technology

[0002] Southern my country is a typical region for multiple cropping per year, with frequent crop rotation. Rice-vegetable rotation is the main rotation pattern. When changing crops in vegetable fields, weeding and sanitation are carried out through chemical or physical weeding techniques.

[0003] Chemical weed control typically uses herbicides. While herbicide-based field clearing can quickly eliminate weeds, herbicide drift or residue can easily cause damage to surrounding and subsequent crops. Furthermore, over-reliance on herbicides can accelerate the development of weed resistance, creating a vicious cycle. High-temperature flame weed control uses the high-temperature flames generated by burning to quickly scorch weed plants, destroying plant cell tissue and causing their death. This achieves control without completely burning the weeds. Simultaneously, the high-temperature flames can kill pests and pathogens in weeds or crop residues, significantly reducing the introduction of pests, diseases, and weeds into subsequent crop fields.

[0004] It is evident that high-temperature flame weeding technology aligns better with the principles of green agriculture. High-temperature flame weeding requires flame-wiring equipment; however, current equipment typically uses high-pressure bottled gases such as liquefied petroleum gas (LPG) as fuel. In field environments, high-pressure gaseous fuels are unstable, pose significant risks, and lack convenient refueling. For continuous field operations, the refueling rate of high-pressure gaseous fuel affects the weeding efficiency of the flame-wiring equipment, thus impacting the speed of agricultural production. Conversely, using readily available liquid fuels such as diesel or methanol often results in incomplete combustion, leading to fuel waste. Furthermore, existing large-scale flame-wiring equipment requires heavy machinery for towing, placing high demands on the operating environment; smaller equipment requires manual pushing and pulling, resulting in low efficiency and failing to meet the demands of modern agriculture for high efficiency, multi-functionality, and intelligent operation. Utility Model Content

[0005] The purpose of this invention is to provide a fuel atomization flame weeding device, which achieves weeding by atomizing and burning normally stored liquid fuel, resulting in higher combustion efficiency. Furthermore, this flame weeding device is remotely controlled and is more convenient to use.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A fuel atomization flame weeding device is characterized by comprising a remote-controlled walking vehicle, an integrated housing mounted on the remote-controlled walking vehicle, and a flame combustion spray chamber mounted at the rear of the remote-controlled walking vehicle via a spray chamber frame.

Detailed Implementation

[0027] This section will elaborate on the technical solution of this utility model through specific embodiments. All directional indicators (including but not limited to "up / down / left / right") in this utility model specification are determined based on the perspective of the accompanying drawings, and their purpose is only to clearly describe the technical features. They should not be interpreted as mandatory requirements for the actual location or operation of the product.

[0028] Example:

[0029] like Figure 1 and Figure 2 The image shows a fuel atomization flame weeding device according to this embodiment, which includes a remote-controlled walking vehicle, an integrated housing 5 mounted on the vehicle, and a flame combustion nozzle 1 mounted at the rear of the vehicle via a nozzle frame 2. The remote-controlled walking vehicle can move via external remote control, specifically using conventional remote control technology. Therefore, the entire device can be remotely controlled via the vehicle, making it more convenient to use. The remote-controlled walking vehicle is commercially available in various styles; this embodiment only describes one type, and therefore the structure of the remote-controlled walking vehicle is not limited to this embodiment.

[0030] The integrated chassis 5 houses a power supply 10, an air compressor 13, and a liquid fuel tank 11. Integrating these components within the chassis 5 results in a more compact structure, easier maintenance and management, and a better overall appearance. The power supply 10 provides the necessary electrical energy to the remote-controlled vehicle, air compressor 13, and liquid fuel tank 11. It includes a battery and conventional charging / discharging control circuitry. The air compressor 13 provides compressed gas for atomizing the liquid fuel and features a conventional air tank capable of storing a suitable amount of high-pressure air. The liquid fuel tank 11 stores the liquid fuel and contains a conventional liquid pump used to pump the stored liquid fuel out.

[0031] like Figure 3 As shown, the spray chamber frame 2 in this embodiment includes a telescopic rod assembly and a U-shaped frame 2.1. The telescopic rod assembly specifically includes two telescopic rods 2.2, which are arranged side-by-side behind the U-shaped frame 2.1. The general structure of the telescopic rod 2.2 is as follows: it mainly consists of an outer sleeve 2.3, an inner tube 2.4 passing through the outer sleeve 2.3, and adjusting bolts 2.5. The front end of the outer sleeve 2.3 has a through hole, and the inner tube 2.4 has multiple corresponding through holes. By passing the adjusting bolts 2.5 through the through holes on the outer sleeve 2.3 and the inner tube 2.4 and connecting them with nuts, locking can be achieved. Connecting the adjusting bolts 2.5 to the through holes at different positions on the inner tube 2.4 can lock the telescopic rod 2.2 to different lengths. The rear end of the outer sleeve 2.3 is connected to the rear of the frame 6 of the remote-controlled vehicle body through a second angle adjustment structure 9, allowing for overall angle adjustment of the spray chamber frame 2. The front end of the inner tube 2.4 is fixedly connected to the rear of the U-shaped frame 2.1.

[0032] like Figure 5 and Figure 6 As shown, the flame combustion nozzle 1 in this embodiment is in the shape of a long strip plate, with a combustion chamber inside and a flame nozzle 1.1 that gradually narrows forward at the front. Specifically, the narrowing is achieved by setting the upper and lower surfaces of the flame nozzle 1.1 as inclined surfaces.

[0033] The flame combustion nozzle 1 is installed at the front of the U-shaped frame 2.1. The two ends of the flame combustion nozzle 1 are connected to the two ends of the U-shaped frame 2.1 through the first angle adjustment structure 7. The tilt angle of the flame combustion nozzle 1 can be adjusted through the first angle adjustment structure 7.

[0034] The first angle adjustment structure 7 and the second angle adjustment structure 9 have the same structural principle. They both include a fixed sector plate, a rotating shaft at the center of the sector plate, positioning holes arranged around the center on the sector plate, fixing holes and locking bolts corresponding to the positioning holes. The locking bolts pass through the fixing holes and the corresponding positioning holes, and the angle is adjusted by the locking bolts passing through different positioning holes.

[0035] The specific installation method of the first angle adjustment structure 7 in this embodiment is as follows: Figure 3 and Figure 4 As shown, the sector plate 7.1 of the first angle adjustment structure is fixedly connected to the end face of the flame combustion nozzle 1, specifically by welding. The rotating shaft 7.3 of the first angle adjustment structure passes through the shaft hole on the U-shaped frame 2.1 to achieve a rotatable connection. A fixing plate 2.6 is provided on the U-shaped frame 2.1, and the fixing hole is provided on the fixing plate. After the angle of the flame combustion nozzle 1 is adjusted by rotation, the locking bolt 7.2 of the first angle adjustment structure passes through the fixing hole and the corresponding positioning hole, and then the nut is connected to achieve the angle locking of the flame combustion nozzle 1.

[0036] The specific installation method of the second angle adjustment structure in this embodiment is as follows: Figure 3 As shown, the sector plate 9.1 of the second angle adjustment structure is welded and fixed to the rear of the frame 6. The rotating shaft 9.3 of the second angle adjustment structure passes through the shaft hole at the rear end of the outer sleeve 2.3 to achieve rotational connection. The fixing hole is located at the rear end of the outer sleeve 2.3. After the spray chamber frame 2 is rotated and adjusted, the locking bolt 9.2 of the second angle adjustment structure is passed through the fixing hole and the corresponding positioning hole, and then the nut is connected to achieve the angle locking of the spray chamber frame 2.

[0037] A row of fuel atomizing nozzles 17 is provided behind the flame combustion chamber 1. The fuel atomizing nozzles 17 penetrate into the flame combustion chamber 1. During use, the liquid fuel is atomized through the fuel atomizing nozzles 17 and sprayed into the flame combustion chamber 1. The rear end of the fuel atomizing nozzles 17 outside the flame combustion chamber 1 is the connection end, which is connected to the compressed air output port of the air compressor 13 and the fuel output port of the liquid fuel tank 11 through the compressed air pipeline 3 and the fuel pipeline 4, respectively.

[0038] Both compressed air line 3 and fuel line 4 include a main line and branch lines connected to the main line corresponding to each fuel atomizing nozzle 17. The main line 3.1 of the compressed air line is connected to the compressed air output port of the air compressor 13, and the main line 4.1 of the fuel line is connected to the fuel output port of the liquid fuel tank 11. The branch lines are connected to the corresponding fuel atomizing nozzles 17. An air input control valve 15 is provided on each branch line 3.2 of the compressed air line. The compressed air input flow rate of the corresponding fuel atomizing nozzle 17 can be controlled by adjusting the air input control valve 15. A fuel input control valve 16 is provided on each branch line 4.2 of the fuel line. The liquid fuel input flow rate of the corresponding fuel atomizing nozzle 17 can be controlled by adjusting the fuel input control valve 16.

[0039] The remote-controlled vehicle body of this embodiment includes a frame 6, four wheels 12, a transmission mechanism 8, and remote-controlled motors 14. An integrated housing 5 is fixedly mounted on top of the frame 6. Wheel frames 6.1 extending downwards are provided at the front and rear ends of both sides of the frame 6. The wheels 12 are rotatably mounted on the lower end of the wheel frames 6.1 via axles 12.1. The wheel frames 6.1 provide the frame 6 with a certain height, allowing for better movement in complex terrains such as orchards, tea gardens, and vegetable fields. Specifically, this embodiment includes two remote-controlled motors 14, located on both sides below the frame 6. Each motor is connected to one of the two wheels 12 on either side via the transmission mechanism 8.

[0040] Two remote-controlled motors 14 drive the wheels 12 on both sides to rotate, enabling the remote-controlled vehicle to steer. Specifically, when traveling in a straight line, the two motors 14 rotate at the same speed, and the wheels 12 on both sides rotate at approximately the same speed. When steering is required, the inner wheel is stopped or rotates at a slower speed, while the outer wheel rotates at a faster speed, thus achieving steering. The remote control of the motors 14, the speed control of the two motors 14, and the steering control are all achieved using conventional control techniques.

[0041] In this embodiment, the transmission mechanism 8 is a sprocket and chain mechanism, specifically including four sprockets 8.1 and two chains 8.2. Two sprockets 8.1 are mounted on the rotating shaft of the remote control motor 14, and the other two sprockets 8.1 are mounted on the axles 12.1 of the two wheels 12 on the corresponding sides. The two chains 8.2 connect the sprockets 8.1 on the axles 12.1 to the sprockets 8.1 on the rotating shaft of the remote control motor 14. In use, the rotation of the remote control motor 14 can drive the two wheels 12 on one side to rotate simultaneously.

[0042] In this embodiment, the power switch 18, air compressor switch 19, and liquid fuel tank switch 20 are located at the rear of the integrated chassis 5. The power switch 18, air compressor switch 19, and liquid fuel tank switch 20 are used to control the opening and closing of the power supply 10, air compressor 13, and liquid fuel tank 11, respectively.

[0043] For ignition during use, this embodiment has an ignition hole 1.2 on the flame combustion chamber 1. During ignition, the operator holds an electronic igniter and inserts it into the ignition hole 1.2 to ignite the flame. In another embodiment, a conventional automatic igniter can be installed inside the flame combustion chamber 1.

[0044] The specific usage procedure of the flame weeding device in this embodiment is as follows:

[0045] 1. Power-on preparation

[0046] Check if the power supply 10 has sufficient power and the amount of fuel in the liquid fuel tank 11 is sufficient. Adjust the telescopic rod 2.2 to a suitable length. Adjust the spray chamber frame 2.1 and the flame combustion spray chamber 1 to a suitable tilt angle. Tilt the flame combustion spray chamber 1 downwards. Turn on the power switch 18 to turn on the power supply 10 and put the equipment into standby mode.

[0047] 2. Startup Operation

[0048] (1) Ignition operation:

[0049] Turn on the air compressor switch 19 to start the air compressor 13 in generating compressed gas, which is then delivered to the fuel atomizing nozzle 17. Then, turn on the liquid fuel tank 20 switch, and the liquid fuel in the liquid fuel tank 11 is delivered to the fuel atomizing nozzle 17 by an internal liquid pump. Under the action of high-pressure gas, the fuel sprayed from the fuel atomizing nozzle 17 will be atomized. The operator then uses a handheld electronic igniter inserted through the ignition port 12 to ignite the fuel. The flame can then be adjusted via the air input control valve 15 and the fuel input control valve 16.

[0050] (2) Start-up of the power unit:

[0051] Press the start switch using an external remote control to start the remote control motor 14. The remote control motor 14 drives the wheels 12 to rotate through the transmission mechanism 8, thus enabling movement.

[0052] 3. Weeding process

[0053] Adjust the height and angle of the flame combustion nozzle 1 according to the on-site environment such as weed type and height, and adjust the appropriate flame intensity and walking speed to achieve the best weeding effect.

[0054] 4. Power off operation

[0055] After weeding is complete, use the external remote control to turn off the remote control motor 14, and manually turn off the power switch 18, air compressor switch 19 and liquid fuel tank switch 20 to complete the equipment shutdown.

[0056] Finally, clean any remaining debris from the flame nozzle 1.1 of the flame combustion chamber 1 to ensure the equipment is clean.

[0057] In agricultural production, flame weeding equipment can be used for weeding and pest control in orchards, tea gardens, vegetable fields, and other areas. These areas are typically large and have many weeds; using flame weeding equipment can significantly improve weeding efficiency without causing chemical herbicide residue damage to crops. However, it is crucial to ensure safe operation when using the equipment to avoid harm to personnel and the environment.
