Description

Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a turning device for processing. Background Art

[0002] Stabilized soil mixing plant is used for the construction of stabilized soil for base of high-grade highways, urban roads, squares and airports. It can continuously mix and produce finished products of fly ash gravel, lime stabilized soil and industrial waste soil stabilized soil with different gradations.

[0003] The stabilized soil mixing station is mainly composed of five systems: a mixing pot, a weighing system, a material conveying system, a material storage system, and a control system. Since the mixing pot needs to be continuously stirred during production and use and thus bears a large load, double-sided welding is required in the actual welding process to improve the stability of the mixing pot parts. When welding on both sides, the mixing pot must be turned over. The current turning method is to use a sling with a crane and a traction rope to slowly adjust the direction of the mixing pot after welding one side of the mixing pot, turn it over and place it on the ground, and then weld the other side. The mixing pot is prone to tipping over during the lifting process, which poses a safety hazard. Utility Model Content
