[0032] The working principle of this utility model:

[0033] First, the staff turns on the travel system 1 and the drive power system 18, moves the utility model to the designated position, and then turns on the drive rotation system 6 and the drive conveying system 17 to excavate and convey the sticky material. When the sticky material is excavated, the sticky material is excavated into the interior of the bucket 4.1 through the bucket teeth 4.2 and the bucket 4.1. At this time, the bucket wheel 4 continues to rotate. When the sticky material is driven by the bucket wheel 4 in the bucket 4.1, due to the action of the chain 4.3, the sticky material will not be excessively adhered to the inner wall of the bucket 4.1, so that the sticky material can fall onto the discharge plate 5, reducing the waste of sticky materials and improving the utilization rate. After the sticky material falls onto the discharge plate 5, it will slide onto the conveyor belt 7 under the action of the inclined placement of the discharge plate 5, thereby completing the transportation. The structural characteristics of the conveyor belt 7 facilitate the transportation of sticky materials. When the conveying is completed or there is too much viscous material on the discharge plate 5, the valve 15 and the water pump 14 can be opened to guide the water in the constant temperature water tank 16 to the nozzle 13 through the connecting water pipe 12, and then sprayed out by the nozzle 13 to clean the discharge plate 5.
