Description

Technical Field

[0001] This utility model relates to the field of garbage bin collection vehicle technology, and in particular to a lifting and weighing device for unmanned garbage bin collection vehicles. Background Technology

[0002] Residential communities typically require the quiet transport of garbage bins filled with trash from within the community to the outside. The full bins are then transported out, weighed, and finally returned to their original locations.

[0003] Currently, community garbage bins are all specialized bins with lids. These bins are usually placed on the ground and need to be moved onto garbage trucks for transportation. The bins need to be weighed manually, which is not only time-consuming and labor-intensive, but also inefficient and wasteful of manpower. In addition, it is noisy and easily disturbs residents. Therefore, there is a need to develop an unmanned garbage bin collection vehicle that integrates loading and weighing to meet the needs of the community. When using an unmanned garbage bin collection vehicle to collect and transport garbage bins, the automatic loading and weighing of the garbage bins are inseparable from the lifting and weighing device. Therefore, the lifting and weighing device is a very important component of the unmanned garbage bin collection vehicle. Utility Model Content
