Description

Technical Field

[0001] The invention belongs to the technical field of transfer, and in particular relates to a workshop transport device. Background Art

[0002] Plastic granules refer to granular plastics, which are generally divided into more than 200 types and subdivided into thousands of types. Common plastic granules include general-purpose plastics, engineering plastics, and special plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester, and polyurethane, and engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene, and polycarbonate silicone. After the plastic granules are produced, there are many processes in the plastic granule production workshop, and one workshop cannot carry out all the production processes, so the plastic granules need to be transported between workshops.

[0003] In transportation, the existing transportation method is mostly a single cart. The storage container containing recycled plastic particles is placed on the cart and moved to a suitable location by the cart. However, there is a problem that when the container is placed on the cart, it is generally moved to the cart manually. Some containers contain a lot of recycled plastic particles and are very heavy. This will take a lot of effort and is relatively inconvenient. Summary of the Invention
