Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy, in particular to a canal silting device. Background Art

[0002] A canal is a man-made waterway, which is divided into a main canal and a branch canal. The main canal and the branch canal are generally built with stone or cement. The purpose of a canal is to irrigate farmland. Water from rivers is often used to irrigate farmland through a "ditch" dug on the ground. It can also be used for hydroelectric power generation. When the existing field canals are used to transport water, silt will accumulate. When the silt accumulates more, it will affect the water transportation. Therefore, it is necessary to regularly dredge the field canals. There are two main ways to dredge the field canals. There are two methods for cleaning silt: one is to dig out silt by an excavator and directly pile it on both sides of the canal; the other is to manually dig out the silt in the canal with tools such as shovels, and then transfer the silt to both sides of the canal. When using an excavator to clean the silt, the cost is high. When manually using tools to clean the silt in the field canal, the efficiency is low. When the canal is deep, when manually using tools such as shovels to transfer the silt at the bottom of the canal to both sides of the canal, the labor intensity of the staff will be greatly increased. Therefore, a canal dredging device is proposed to address the above problems. Utility Model Content
