[0002] Invasive plants refer to plants that are not naturally occurring and evolved in a specific regional ecosystem, but are later introduced from other regions through different channels. If these plants can grow and reproduce in a natural state, they constitute an invasion of alien plants. Invasive plants reproduce by seeds and rhizomes, have strong reproductive ability, fast transmission speed, rapid growth and strong ecological adaptability, and can grow from mountain slopes and forests to marshes.

[0003] Currently, invasive plants are usually eradicated by cutting or using chemical drugs. Although cutting can quickly cut off the growing invasive plants, if the roots and seeds are not timely treated, they can easily regrow and reproduce, reducing the eradication effect. Using chemical drugs for eradication can pollute the land, reduce the fertility of the land and harm the growth of native plants. SUMMARY

The refractory layer 1101 is arranged on the left side of the inner wall of the square inner shell 18. The inner top plate 1102 is arranged on the top of the refractory layer 1101. The refractory arch 1103 is arranged on the lower surface. The gasification space is constructed by the refractory layer 1101 and the refractory arch 1103. The discharge pipe support 1104 is arranged on the left side of the inner top plate 1102. The fire door 1105 and the gasification air inlet door 1106 are arranged on the top of the left side wall of the square inner shell 18 from top to bottom. The grate support plate 1107 is welded on the middle lower part of the square inner shell 18. The two rotating grates 1108 are arranged on the front of the square outer shell 16. The rotating grates 1108 are supported by the grate support plate 1107. The refractory layer 1101 and the refractory arch 1103 form a high-temperature-resistant sealed space. The inner top plate 1102 and the grate support plate 1107 support the top and the middle lower part respectively, forming a physical space for material gasification.

[0033] As a preferred solution, the rotary grate 1108 further comprises a sleeve 1109, a sleeve flange 1110, a sealing flange 1111, a stainless steel 310S short rod 1112, an air outlet hole 1113 and a handle 1114. The two sleeves 1109 are welded to the outer wall of the supporting plate 1107 and pass through the square inner housing 18, the heat insulation layer 17 and the square outer housing 16. The rotary grate 1108 passes through the inner cavity of the sleeve 1109. The sleeve flange 1110 is welded to the front end of the sleeve 1109. The rotary grate 1108 passes through the sleeve 1109 at both ends. The sealing flange 1111 is movably arranged on the outer wall of the rotary grate 1108 and is locked with the sleeve flange 1110 by bolts. The sealing flange 1111 and the sleeve flange 1110 are sealed by a packing rope as a sealing material to realize sealing when the rotary grate 1108 rotates. The rotary grate 1108 is partially welded with a stainless steel 310S short rod 1112 in the furnace as a grate piece to solve the problem of high-temperature melting. The rotary grate 1108 is made of hollow stainless steel 316L material, which is resistant to high temperature and corrosion. The rotary grate 1108 is provided with an air outlet hole 1113 and a handle 1114 at the hand-shaking end. The handle 1114 is screwed on the hand-shaking end of the rotary grate 1108 for shaking and turning the rotary grate 1108. The air outlet hole 1113 is in communication with the inner cavity of the rotary grate 1108. The other end of the rotary grate 1108 is in communication with the atmosphere. When the rotary grate 1108 is subjected to high temperature of the fire bed in the gasification device 11, the external cold air enters through the non-blocking end of the rotary grate 1108 by using the cold and hot convection force, and the hot air is discharged from the air outlet hole 1113 after cooling the rotary grate 1108.

[0034] The rotary grate 1108 is manually turned by the handle 1114 to stir the material and promote uniform gasification. The hollow structure utilizes the principle of cold and hot convection. The external cold air enters from one end of the grate, and the hot air is discharged from the air outlet hole 1113 after cooling the grate to prevent overheating of the grate.

[0035] After the cut foreign invasive plants are dried by the drying assembly 15, they are pushed into the gasification assembly 11 by the gas check valve plate 1503. The check valve plate 1503 is automatically closed to isolate gas backflow. Dry straw is initially added through the fire door 1105 to ignite and form a fire bed. Subsequently, the dried material is continuously fed.

[0036] External air is introduced through the gasification air inlet door 1106. The natural suction force is formed by the height difference of the exhaust pipe 3 to make the air enter the gasification space. The material is heated and decomposed under oxygen-deficient or oxygen-limited conditions to generate combustible gas (such as CO, H2, CH4, etc.). The residual ash falls into the ash box 1201 of the ash chamber 12 for temporary storage. The generated fuel gas descends under the action of gas flow force, enters the ash chamber through the gap between the rotary grates, and is transported to the oxidation assembly 14 through the throat pipe 1203 for combustion.

[0037] The chimney effect of the exhaust gas discharge pipe 3 forms a high difference gravity, without additional power equipment, to realize the natural circulation of air suction and gas discharge, which is suitable for the field without electricity environment; the heat generated in the gasification process is transferred to the hot air assembly 13, and after heating the air, it is used for material drying of the drying assembly 15, to form a self-supply heat cycle, and reduce energy consumption.
