Its main components include slag, cement, coal ash powder, lime, etc. After the soft soil curing agent is produced, it needs to be bagged and packaged. To ensure the same weight, a weighing and packaging device is required for bagging, which effectively improves the bagging efficiency. In the prior art, a weighing and packaging device with the authorization announcement number of CN214296668U is disclosed. A weighing mechanism is provided at the top of the upper support frame, and a packaging mechanism is provided below it.
