[0002] In the field of water conservancy engineering, water conveyance channels, as key infrastructure for water resource transportation and allocation, directly affect the normal operation and effectiveness of the water conservancy system. With the continuous development of the economy and society, the scale of water conservancy projects is constantly expanding, highlighting the increasing importance of channel siltation. Efficient channel siltation technology can not only effectively improve water resource utilization efficiency but also ensure agricultural irrigation water needs, playing a vital role in maintaining the long-term stable operation of water conservancy projects.

[0003] However, in water conveyance channel silt removal operations, traditional methods mainly rely on manual labor using tools such as shovels. This method has many drawbacks. On the one hand, it requires a large number of people to participate in the silt removal work, resulting in a waste of resources. On the other hand, manual silt removal is slow, and for long-distance water conveyance channels, the silt removal process often takes a lot of time, failing to meet the channel silt removal needs in a timely manner. In addition, manual operation is limited by physical strength and the working environment. In complex conditions such as deep silt, the silt removal effect is difficult to guarantee, making it impossible to achieve efficient treatment of channel silt and severely restricting the operational efficiency of water conveyance channels.

[0004] Therefore, improving the efficiency of silt removal during channel dredging has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The present invention aims to provide a channel silt removal device for water conservancy projects to overcome the shortcomings mentioned above.
