Description

Technical Field

[0001] The invention belongs to the technical field of canal desilting, and in particular relates to a canal desilting device. Background Art

[0002] In water conservancy projects, ditches are often needed for irrigation or drainage. After a period of use, silt will accumulate at the bottom of the channel. The silt affects the flow of the ditch, so regular dredging operations are often required.

Due to the long-term accumulation of silt, it is difficult to break it up, resulting in low work efficiency. Second, the use of ditch dredging equipment. Most ditch dredging equipment uses a sludge pump to extract the silt in the ditch for cleaning. Due to the lack of a structure to crush large impurities in the silt, large impurities directly enter the sludge pump, causing the sludge pump to be blocked, affecting the stability of the device during use.

[0057] When this scheme is implemented, the output shaft of the motor rotates to drive the crushing wheel to rotate, and the hydraulic cylinder 7 drives the crushing wheel to move from top to bottom (when the silt layer is thin, the crushing wheel can also not move up and down). The rotation of the crushing wheel drives the silt block to move toward the shovel plate 2, and the silt at the bottom of the crushing ditch is a silt block. Then the device moves forward, and the silt block enters the diversion channel and is lifted by the inclined plate 202 and falls onto the conveyor belt 4, moves to the guide plate 5 through the conveyor belt 4, and flows to the ground in the specified direction through the guide plate 5.

[0058] Compared with the traditional manual cleaning, the setting of the crushing wheel improves the work efficiency. Compared with the traditional pumping of sludge, the use of the conveyor belt 4 to convey the sludge does not cause the problem of pump clogging, thereby ensuring the stability of the device during use.
