Description

Technical Field

[0001] The invention relates to the technical field of weeding equipment, and in particular to a steam flame weeder and a use method thereof. Background Art

[0002] With the development of science and technology and the improvement of environmental awareness, people are paying more and more attention to the sustainability of agricultural production. Although traditional chemical weed control methods are effective, long-term use will cause pollution to the soil and environment, affecting the growth and quality of crops. Therefore, seeking an environmentally friendly and efficient weed control method has become an urgent need in the agricultural field. In recent years, steam weed control technology and flame weed control technology have gradually emerged and have received widespread attention for their unique advantages.

[0003] Steam weed control technology is a method of killing weeds using high-temperature and high-pressure steam. When steam comes into contact with weeds, its high temperature and high pressure will cause the weed tissue to expand rapidly, destroying the cell structure, thus achieving the weed control effect. In addition, steam can also inactivate weed seeds on the surface of the soil, further preventing the regeneration of weeds.

[0004] Flame weeding technology uses high-temperature flames to instantly evaporate the moisture on the surface of the grass, raising the temperature near the grass roots, thereby completely killing the grass roots and achieving the purpose of weeding. Compared with chemical herbicides, flame weeding technology is more environmentally friendly and non-toxic. It not only reduces the pollution of chemicals to the environment, but also has no side effects, and can effectively protect the healthy growth of fruit trees, grapes, vegetables and other crops.

The flamethrower 6 is installed at the front of the frame 1, connected to the liquefied gas storage tank 5, and the remote control receiver 9 controls the ignition and flame spraying intensity.

[0051] The steam generator 7 generates high-temperature steam by burning liquefied gas to heat pure water, and the high-temperature steam is sprayed onto the surface of weeds through the steam ejector 8 to kill the weed roots and seeds. The steam generator 7 is fixed to the front of the frame 1 and connected to the liquefied gas storage tank 5. The steam generator 7 includes a water injection device (for adding pure water) and a heating device (generating steam by burning liquefied gas).

[0052] The steam ejector 8 ejects high temperature steam to the weeds on the ground to kill the roots and seeds, thereby achieving the purpose of completely removing the weeds. The steam ejector 8 is directly connected to the steam generator 7 and is installed at the front of the frame 1.

[0110] Among them, in the field of urban gardening:

[0111] Flame weeding: In urban garden maintenance, lawns, flower beds, parks and other places often need weeding. Flame weeders can quickly and effectively remove weeds in these areas without polluting the soil, which is beneficial to environmental protection.

[0112] Steam weeding: Steam weeding is also very suitable in urban gardens. Especially in some areas where high hygiene standards need to be maintained, such as golf courses, football fields, etc., steam weeding can not only effectively remove weeds, but also avoid the impact of chemical herbicides on the environment and human health.

[0113] In the field of agricultural production:

[0114] Flame weeding: In agricultural production, flame weeders are mainly used for weeding in orchards, tea gardens, vegetable fields, etc. These areas are usually large in area and have more weeds. The use of flame weeders can greatly improve the weeding efficiency without causing harm to crops.

[0115] Steam weeding: Steam weeding also has certain applications in agricultural production. It can effectively remove weeds in the field without destroying the soil structure, reduce the occurrence of pests and diseases, and improve the yield and quality of crops.

[0116] It should be noted that whether it is flame weeding or steam weeding, it needs to be selected according to the specific use environment and scenario. For example, for some temperature-sensitive crops, such as vegetables and flowers, steam weeding may be more appropriate; while for some rough and heat-resistant areas, such as orchards and tea gardens, flame weeding may be more effective. At the same time, when using these weeding methods, it is also necessary to pay attention to safe operation to avoid damage to personnel and the environment.

[0117] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
