Automatic rain-increasing hail-suppression rocket launcher

The invention provides an automatic rain-increasing hail-suppression rocket launcher which comprises an electronic compass, an orientator, an elevating machine, a rotary disc and a steering gear box. The elevating machine adopts a double-screw structure and double-point support, so that the stability of rocket launching is improved; in addition, the double-lead-screw structure has the self-locking characteristic, and the internal structure does not easily rotate and slide like a rotating optical axis, so that locking is not needed, and the launching preparation time is shortened. The steering gear box is of an integrated rotary assembly structure, 360-degree free rotation can be achieved, the occupied size is small, the weight is light, the steering gear box is composed of a servo motor driving rod and a bearing with a gear, a rotary connecting rod and the bearing are integrally assembled, the fit clearance is smaller than that of a bulk structure, rotary delay is effectively reduced, and positioning of a sys
