CATALYST SOWING DEVICE AND HIGH-TEMPERATURE-RESISTANT PRECIPITATION-INCREASING ROCKET HAVING SAME

A catalyst sowing device and a high-temperature-resistant precipitation-increasing rocket having the catalyst sowing device. The catalyst sowing device comprises a main body portion (21) and a catalyst core (22); an accommodating cavity is provided in the main body portion (21), and a sowing channel (2121) is provided on the main body portion (21); the catalyst core (22) comprises a warm cloud catalyst, the catalyst core (22) is mounted in the accommodating cavity, and an ignition channel (221) extending along the length direction of the catalyst core (22) is provided in the catalyst core (22). The catalyst sowing device further comprises a main ignition portion (23) and a first auxiliary ignition portion (24), so as to prevent occurrence of a phenomenon that the catalyst core (22) cannot be ignited. Ignition from both ends can also realize transfer from both ends to the middle, so that the ignition efficiency of the catalyst core (22) is higher.
