Description

Technical Field

[0001] The invention relates to the field of channel dredging, and more specifically to a channel dredging device for water conservancy projects. Background Art

[0002] The water conservancy project channel is a lifeline for farmland crops and one of the important links to ensure farmland production. It is crucial to improve the function of farmland water conservancy field drainage and irrigation channels. The water conservancy project channel is generally built with cement stones and other materials. The riverbed of this type of water conservancy project channel is generally narrow, and stones or cement are 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 water flow rate will slow down, affecting irrigation. At present, agricultural channel dredging is usually carried out manually, which consumes a lot of manpower. Some mechanical dredging mostly accumulates silt on both sides of the channel, affecting the appearance and making it difficult to clean up later. Some dredging devices cooperate with collection devices for centralized collection, but the collection capacity is limited, which affects the dredging efficiency. Some silt spreading devices have poor spreading effects, which are difficult to debug according to the actual spreading area, and it is difficult to choose the appropriate side for spreading according to actual usage.

[0025] like Figure 1 , 2As shown, the transmission power supply unit 9 includes a diesel transmission unit 91 installed on one side of the upper surface of the frame 1, and a power generation device 92 is installed opposite to the diesel transmission unit 91.

By rotating the side bucket 16, it can be fitted close to the inclined side wall of the channel, and the reinforcement rod 172 can be sleeved on the fixed screw 173 at a suitable position and fixed by a nut, which can enhance the stability of the side bucket 16 during operation. When the span of the channel is large, the span of the wheel body of the frame 1 can be adjusted. When adjusting, the locking bolt on the locking seat 22 can be loosened to extend the extension frame 21. During this process, the transmission clamp rod 19 can slide in the cross groove 18 of the transmission shaft 94, and the external bearing 20 prevents the transmission clamp rod 19 and the extension frame 21 from interfering with each other.
