Description

Technical Field

[0001] The utility model belongs to the technical field of silt removers for farmland water conservancy construction, and in particular relates to a silt remover for farmland water conservancy construction. Background Art

[0002] In agricultural production, river water is usually introduced into farmland for irrigation, which requires the construction of water conservancy engineering channels in farmland. Irrigation channels are waterways that connect irrigation water sources and irrigated land, and transport and distribute the water drawn from the water source to various parts of the irrigation area. Within an irrigation area, irrigation channels are divided into five levels according to the size of the controlled area: main channels, branch channels, ditches, farm channels, and small ditches. Irrigation areas with complex terrain and large areas can also add multi-level channels such as main trunks, branch trunks, branches, and ditches. Irrigation areas with smaller areas can reduce the number of channel levels. The longitudinal and cross-sectional areas of the channels should be designed according to the design irrigation flow and design irrigation water level. In terms of design, the channels of farmland water conservancy projects are generally built with cement stones and other materials. The riverbed of such water conservancy project channels is generally narrow, with stones or cement laid on both sides. The construction is solid and flat, and the depth of the channel is shallow. However, due to the strong wind and sand in the wild, a large amount of silt will be deposited at the bottom of the channel, and the river water itself will also carry a large amount of silt into the channel. The accumulated silt will make the riverbed higher and the flow rate of water will slow down, affecting irrigation. Over time, the silt in the channel will accumulate thicker and thicker, seriously affecting the water delivery capacity and speed of the open channel. Therefore, every one to three years, it is necessary to use corresponding dredging equipment to dredge the channel.

[0003] The prior art farmland water conservancy construction silt remover has the following disadvantages during use:

[0004] On the one hand, when in use, most of them use a water pump to suck the sewage in the river, and generally a filter is set at the water inlet to intercept dirt and sludge in the sewage. However, the silt remover is not provided with a structure that can clean the surface of the filter. Even if it is set, it is driven by an electric device, and it is impossible to use the power generated by the water pump to clean the surface of the filter;

[0005] On the other hand, the filter is fixed in the silt remover in an undetachable manner, which makes it inconvenient to remove and replace the filter after long-term use. For this reason, we propose a silt remover for farmland water conservancy construction. Utility Model Content
