Description

Technical Field

[0001] This invention relates to the field of artificial snowmaking technology, and in particular to a hoisting snowmaking machine. Background Technology

[0002] The development of artificial snowmaking technology can be traced back to the 1930s. The earliest snowmaking method involved using ice crushers to extract crushed ice and then blowing it onto ski slopes. In 1950, P. Wayne pioneered the use of compressed air and throttling nozzles to produce snow crystals, creating the first truly functional artificial snowmaking machine. Today, with the increasing popularity of winter sports, artificial snowmaking technology has made significant progress.

[0003] Currently, indoor snowmaking machines have rapidly taken over the mainstream market due to their high efficiency and good snowmaking effect. However, due to limitations such as site size, air circulation, wet-bulb temperature, and wind speed, indoor snowmaking machines on the market generally have the following disadvantages: 1. The machine angle and rotation cannot be adjusted, resulting in the site not being fully covered by snow, and the spray distance cannot be adjusted; 2. The snowmaking machine cannot be raised or lowered, making it difficult for maintenance and operation personnel to operate, etc. Summary of the Invention

[0004] The purpose of this invention is to provide a suspended snowmaking machine, which is suspended from the ceiling of an indoor ski resort by a mounting cylinder, and sprays water mist through the snow cannon body. The water mist condenses during the fall of the water mist, which is then used to make snow by utilizing the low temperature environment of the indoor ski resort.

It is equipped with bearings and motors, which can drive the snow cannon body to rotate, increasing the snowmaking area. It is equipped with a pitch adjustment cylinder to adjust the pitch angle of the snow cannon body. Attached Figure Description
