Description

Technical Field

[0001] This invention relates to the field of straw burning vehicle technology, specifically a straw burning vehicle. Background Technology

[0002] In the agricultural sector, straw disposal has always been a pressing issue. Traditional straw disposal methods, such as open burning, while rapidly reducing straw volume, lead to severe air pollution problems, including the generation of large amounts of smoke, harmful gases (such as carbon monoxide and sulfur dioxide), and particulate matter (PM2.5 and PM10). These pollutants not only damage the environment but also seriously affect human health, especially the respiratory and cardiovascular systems. Furthermore, open burning can also cause fires, posing a safety threat to farmland and surrounding facilities.

[0003] To address this issue, the industry has attempted to develop various straw treatment technologies, including mechanized crushing and returning to the field, bio-fermentation conversion, and utilization as biomass energy. However, these technologies all face certain limitations in practical applications. While mechanized crushing and returning to the field can reduce pollution from burning, the direct return of large amounts of uncomposted straw to the field may affect the growth of the next season's crops and even lead to the breeding of pests and diseases. Bio-fermentation conversion technology is limited by issues such as long fermentation cycles, high processing costs, and product market acceptance. As for utilization as biomass energy, although it has long-term environmental and economic benefits, it is limited by collection, transportation, and storage costs, as well as the maturity of energy conversion technology, making it difficult to promote on a large scale in the short term.

[0004] Against this backdrop, it is particularly important to develop a technical solution that can effectively treat straw, reduce environmental pollution, and take into account both agricultural production and economic benefits. Straw burning, as a direct and rapid treatment method, is a highly promising solution if it can be carried out under the premise of controlling pollution emissions. However, traditional straw burning methods lack effective pollution control measures and are difficult to meet modern environmental protection requirements. Summary of the Invention

[0013] The straw burning vehicle proposed in this invention has the following advantages:

[0014] 1. This invention uses a liftable collection hood to collect the straw to be burned and guide it into the burning mechanism. At the same time, the soil turning roller is activated to turn the soil over and dig out the straw roots buried underground so that they can be burned completely. This ensures that the straw is fully collected and prepared, providing a foundation for the subsequent burning process. At the same time, the soil turning operation improves the burning efficiency of straw and reduces the breeding of pests and diseases.

[0015] 2. This invention utilizes fuel in the fuel tank for combustion by activating the flame gun. At the same time, the amount of air in the collection hood is adjusted by the air intake regulating component to control the combustion effect, thereby achieving efficient combustion of straw. Furthermore, the air regulation ensures the stability and controllability of the combustion process and reduces pollutants generated by incomplete combustion.

[0016] 3. This invention draws toxic and harmful gases produced by incineration into the evaporation chamber by activating the exhaust fan. Inside the evaporation chamber, the gas exchanges heat with water through a U-shaped evaporation tube and is further heated by an electric heating plate. Subsequently, the gas undergoes preliminary filtration through a water tank and secondary filtration through an activated carbon filter before being finally discharged. This effectively purifies the gases produced by incineration, reduces the emission of harmful substances, and protects the environment. At the same time, the design of the water circulation system improves resource utilization and reduces energy consumption.

[0017] 4. As the incineration vehicle moves, the soil scraping component scrapes the tilled soil flat and covers the burned straw. Subsequently, the soil compaction roller compacts the land, further enhancing the fire extinguishing effect. At the same time, high-temperature water vapor in the steam chamber is sprayed out through the nozzle to extinguish the fire and increase the soil temperature, thereby achieving rapid fire extinguishing and soil treatment after incineration, reducing the risk of fire, and increasing the soil temperature, which is beneficial to the growth of subsequent crops. In addition, the spraying of high-temperature water vapor further enhances the fire extinguishing effect and increases the pest killing rate.

[0018] 5. This device effectively solves the technical problems of low straw processing efficiency, large pollution emissions, poor safety, and difficulty in balancing agricultural production and economic benefits in existing technologies. This device not only realizes efficient burning and environmentally friendly treatment of straw, but also improves the efficiency and economic benefits of agricultural production, and has significant innovation and practicality.

[0042] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0043] Step 1: When using the vehicle, fill the inner cavity of the water tank 8 with an appropriate amount of clean water, and fill the inner cavity of the fuel tank 7 with fuel. Start the vehicle body 1 and use the vehicle body 1 to adjust the height of the collection hood 51 until it is adjusted to a suitable height. Start the hydraulic cylinder 68. The hydraulic cylinder 68 can adjust the height of the soil compaction roller 66 through the connecting rod 67 until it is adjusted to a suitable height. Start the motor 56. The output end of the motor 56 rotates, which drives the second sprocket 58 to rotate through the connecting rod 57. This, in turn, drives the turning roller 54 to rotate through the chain 59 and the first sprocket 55. The rotation of the turning roller 54 can till the land and dig out the roots of the straw buried underground. Turn on the flame gun 53. The fuel in the inner cavity of the fuel tank 7 is transported to the inner cavity of the flame gun 53 through the fuel delivery pipe 18 and the fuel pipe 52, causing the flame gun 53 to spray out a high-temperature flame. 3. The high-temperature flames sprayed can cause the straw and the roots of the dug-out straw to burn. Furthermore, since conventional spray flames (800-1200℃) can only affect the soil layer 0-5cm below the surface, and the overwintering depth of common pests such as rice stem borers is 5-10cm below the surface, cutworms are 10-15cm below the surface, and wireworms are 15-20cm below the surface, and the egg-killing conditions require the temperature to be maintained above 55℃ for 10 minutes, the high-temperature flames sprayed by the flame gun 53 can directly act on the pests themselves under the surface of the plowed soil, causing the exposed insect eggs to be directly burned, thereby increasing the mortality rate of the insect eggs. The vehicle body 1 moves the collection cover 51 and the installation box 61, so that the straw in different locations can be burned and the pests killed as the vehicle body 1 moves.

[0044] Step 2: The amount of air entering the inner cavity of the collection hood 51 can be adjusted according to different situations, thereby adjusting the burning effect of the straw. By activating the electric telescopic rod 515, the rack 514 is driven to move up and down. The movement of the rack 514 can cause several gears 513 to drive several louvers 512 to rotate synchronously through the first rotating rod 511. This can adjust the opening degree of the front side of the inner cavity of the collection hood 51, thereby adjusting the amount of air entering the inner cavity of the collection hood 51, and thus adjusting the burning effect of the straw in the inner cavity of the collection hood 51.

[0045] Step 3: Start the exhaust fan 9, reciprocating plunger pump 12 and electric heating plate 14. Starting the exhaust fan 9 can create negative pressure in the inner cavity of the vehicle body 1, thereby drawing the toxic and harmful high-temperature gas produced by the burning of straw in the inner cavity of the collection hood 51 into the inner cavity of the exhaust fan 9, and then into the inner cavity of the evaporation chamber 2 through the first air pipe 10. The toxic and harmful high-temperature gas in the inner cavity of the evaporation chamber 2 can flow into the inner cavity of the water tank 8 through the second air pipe 15. The clean water in the inner cavity of the water tank 8 can perform preliminary filtration of the toxic and harmful high-temperature gas. The gas after preliminary filtration can flow into the inner cavity of the activated carbon filter device 17 through the third air pipe 16. The activated carbon filter device 17 performs secondary filtration of the gas, and the gas after secondary filtration is discharged through the activated carbon filter device 17.

[0046] Step 4: The electric heating plate 14, once activated, heats the U-shaped evaporator tube 11 and further heats the toxic and harmful gases inside the evaporation chamber 2. This heating partially vaporizes or softens volatile substances (such as tar and VOCs) in the flue gas, causing fine particles (PM2.5) to adhere and form larger aggregates, making them easier to trap during subsequent water bath in the water tank. The increased temperature also reduces the viscosity of the flue gas and enhances the diffusion ability of gas molecules in water, particularly improving the capture efficiency of water-soluble pollutants (such as NH3 and some VOCs). The reciprocating plunger pump 12, once activated, draws water from the inner chamber of the water tank 8 into the U-shaped evaporator tube 11. The water flows through the inner cavity of the evaporation tube 11 and along the inner cavity of the U-shaped evaporation tube 11. After the water flows into the inner cavity of the evaporation chamber 2 along with the U-shaped evaporation tube 11, the water in the inner cavity of the U-shaped evaporation tube 11 can be initially heated by the toxic and harmful high-temperature gas. When it flows to the electric heating plate 14, the water in the inner cavity of the U-shaped evaporation tube 11 can be further heated, causing it to evaporate into water vapor. The evaporated water vapor can then flow into the inner cavity of the steam chamber 4 through the conveying pipe 13. The water vapor in the inner cavity of the steam chamber 4 can then flow into the inner cavity of the nozzle 611 through the connecting pipe 69 and the water pipe 610, and the high-temperature water vapor is sprayed out through the nozzle 611.

[0047] Step 5: As the vehicle body 1 moves, when the scraper 65 moves to the straw burning area, the scraper 65 can be used to level the soil turned over by the turning roller 54. The coil spring 64 can ensure that the scraper 65 is always in contact with the ground. After the scraper 65 levels the soil turned over, it can bury the hot soil at the burning area under the ground surface, which can not only increase the temperature under the ground surface, but also use the soil for initial fire extinguishing. As the vehicle body 1 moves, the pressing roller 66 can be used to compact the leveled land, further enhancing the fire extinguishing effect. At the same time, the high-temperature water vapor sprayed by the nozzle 611 can further enhance the fire extinguishing effect and increase the soil temperature, thereby further increasing the pest killing rate.

[0048] Step Six: This device effectively solves the technical problems of low straw processing efficiency, large pollution emissions, poor safety, and difficulty in balancing agricultural production and economic benefits in existing technologies. This device not only achieves efficient burning and environmentally friendly treatment of straw, but also improves the efficiency and economic benefits of agricultural production, and has significant innovation and practicality.
