Description

Technical Field

[0001] The invention relates to the field of construction machinery, and in particular to a cement bag recovery device for construction. Background Art

[0002] Cement becomes a slurry when mixed with water. It can harden in the air or in water, and can firmly bond materials such as sand and stone together. It is widely used in civil construction, water conservancy, national defense and other projects. However, after building a house, discarded cement bags often pile up like mountains. They are usually collected manually. Before collection, the cement bags need to be shaken to shake out the remaining cement in the bags. A large amount of dust will be generated in the shaking process, which will have a certain impact on the health of the workers. At the same time, the work efficiency is relatively low, and it is time-consuming and labor-intensive.
