Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a silt removal device for water conservancy projects. Background Art

[0002] Water conservancy projects are a general term for various engineering projects built to control, utilize and protect surface and underground water resources and the environment. According to their purpose or service objects, they can be divided into flood control projects to prevent flood disasters, and farmland water conservancy projects to prevent drought, waterlogging and waterlogging to serve agricultural production.

[0003] In water conservancy projects, it is often necessary to treat the silt in rivers and ditches for subsequent drainage and water storage operations. However, the existing dredging devices cannot adapt well to rivers and ditches of different depths, and the devices need to be frequently moved to treat the silt in different areas of the rivers and ditches. The working efficiency is low, and a filtering mechanism is often provided to filter impurities in the silt so that the silt can be put into subsequent utilization. However, the large stones contained in the silt can easily cause the filtration mechanism to be blocked, affecting the filtering effect of the silt. For this reason, we propose a dredging device for water conservancy projects. Utility Model Content

[0020] Effective effects:

[0021] The utility model provides a dredging device for water conservancy projects. It has the following beneficial effects:

[0022] In the dredging device for water conservancy projects, two sets of nuts in the auxiliary mechanism are loosened to release the fixation of the connecting hose 1, so that the silt suction head moves downward, and the height of the silt suction head can be adjusted to adapt to rivers and ditches of different depths. The two sets of nuts are re-tightened to limit the position of the silt suction head, and the silt suction head is driven to move by the electric telescopic rod, so that its position in the river channel canal can be further adjusted to absorb silt at different positions in the river channel canal. At the same time, the silt suction head can be driven to move back and forth left and right in the river channel canal through the reciprocating screw and the movable block to increase the range of silt absorption. There is no need to frequently move the entire device, and the silt absorption in a certain range of the river channel canal can be well performed, which effectively improves the work efficiency.

[0023] In the dredging device for water conservancy projects, impurities and large stones in the silt can be filtered out through the filter plate so that they can be used as planting fertilizer later. The large stones in the silt can be crushed by the motor 2 and the vertical shaft in cooperation with the eccentric crushing roller to prevent large stones from clogging the filter plate and affecting the filtering effect on the silt. At the same time, the eccentric force generated by the rotation of the eccentric crushing roller causes the treatment tank to move back and forth left and right between the L-shaped side plates through the slider and the slide rod, which can generate vibration and improve the filtering effect on the silt.
