Description

Technical Field

[0001] The utility model relates to the technical field of excavation equipment, in particular to a water diversion tunnel excavation device which is convenient for collecting materials. Background Art

[0002] A water diversion tunnel is a tunnel used to divert or transport water for power generation, irrigation, industry and daily life. It is one of the important components of a water conservancy hub. The excavation of a water diversion tunnel must be selected based on topography, engineering geology, hydrogeology, hydrology and other conditions, and must be excavated using a tunnel boring machine.

[0003] At present, most of the common water diversion tunnel excavation equipment on the market are similar in structure. They are generally driven by crawlers. The head of the excavator is lifted by a hydraulic cylinder. The high-speed rotating head crushes the rocks on the excavation surface, and the bucket under the head scoops up the fallen gravel. The rotating lever inside the bucket sweeps the gravel material onto the conveyor belt, which is transported backwards through the conveyor belt. A truck at the rear receives and transfers it. There are some functional deficiencies in actual use and there is room for improvement. For example, when collecting fallen rock materials, some fine sand and soil will also enter the shovel disc at the same time. There is a certain gap between the lever and the shovel disc, and materials such as sand and soil are easily missed. Some fine sand and gravel are also easily stuck in the gap between the lever and the shovel disc, causing scratches between the lever and the shovel disc. It does not have the function of facilitating the collection of materials and reducing residual sand and soil.

[0004] Now, a new type of water diversion tunnel excavation equipment which is convenient for collecting materials is proposed to solve the above problems. Utility Model Content
