Abstract:
A hot reflow resistance nozzle (3) used for a weeding machine, comprising a cover (31), a connection portion (32), and a folded portion (33); the folded portion (33) comprises an annular folded face (331) and a support portion (332), the folded face (331) is provided thereon with at least one air outlet (333), and the distance between the air outlet (333) and the bottom end face of the support portion (332) is less than or equal to 2 cm. Compared with the prior art, the nozzle (3) enables a part of a hot airflow, after being blocked by the ground and returning to the inside of the nozzle (3), to be quickly diffused to the outer peripheral side and then instantly discharged from the air outlet on the top of the closely situated folded portion (33), efficiently avoiding the hot airflow flowing from, the gap between the bottom end face of the nozzle (3) and the grassland where the bottom end face is located, to the grassland near the outer periphery of the nozzle (3); the hot airflow can be cooled while being discharged, avoiding any damage to the surrounding vegetation needing to be preserved, and ensuring the safety of a user.
