Description

Technical Field

[0001] The utility model relates to the technical field of airport spreading, in particular to an airport spreading vehicle. Background Art

[0002] The area of ​​an airport is very large. For example, the runway of a medium-sized airport is 40m wide and more than 2,600m long, with more than 100m of open space on each side, and several hundred meters of open space at both ends; it should be about 80 hectares; in winter, when heavy snowfall and severe cold cause snow and ice on the road, in order to ensure smooth road traffic, a spreader is needed to spread snow-melting agent. The operating area of ​​a traditional spreader is only four or five meters, and it can only be used for spreading on ordinary roads. Since the road at the airport is more than 40m, the operating efficiency of the traditional spreader is low and it is difficult to meet emergency needs. For example, Chinese patent application No. 202322065217.8 discloses a liquid snow-melting agent spreader, including a vehicle and a spreading water tank. The spreading water tank is arranged on the frame of the vehicle. The spreading water tank is spliced ​​by single water tanks, and only nozzles are designed at the front and rear of the vehicle. The operating area is limited and is only suitable for spreading on conventional roads. It cannot meet the spreading needs of the airport. Therefore, an airport spreader is proposed to solve the above problems. Utility Model Content

The working area of ​​the cloth is more than three times that of the traditional spreading vehicle, which greatly improves the work efficiency. The safety pull 1 is arranged between the other end of the spreading support arm 3 and the rotating shaft 12.
