[0013] 1. This hydraulic engineering sediment screening machine is provided with a blockage cleaning component group. In the current sediment screening machine, the screen lacks a cleaning mechanism. During long-term use, the screen holes are easily clogged with sediment, which in turn affects the screening efficiency of the screening machine. In the corresponding designed blockage cleaning component group, after long-term use of the sediment screening machine component group, the screening mesh will be clogged. When it is necessary to clean the screening mesh to solve the blockage, first close the entire sediment screening machine component group, then unscrew the screws in the blockage cleaning component group from the slider and the lower frame. After unscrewing, the slider, the upper cross pipe and the nozzle can be moved by holding the adjustment block on one side of the slider, and the working end of the nozzle is facing the bottom of the screening mesh. At this time, the liquid pump on the water supply pipe can be turned on. The liquid pump will pump water from the water supply assembly connected to one end of the water supply pipe through the water supply pipe. The water enters the upper horizontal pipe through the liquid pump and the water supply pipe, and then is sprayed out through the nozzle on the upper horizontal pipe. The water sprayed from the nozzle will spray the bottom of the screening mesh. The sprayed water column can flush out the mud and sand blocked in the screening mesh, thereby solving the blockage problem. Compared with the prior art, the present blockage cleaning component group structure manually cleans the blockage on the screening mesh by personnel. The blockage in the screening mesh can be efficiently cleared by directly moving the position of the upper horizontal pipe and the nozzle, thereby improving the cleaning efficiency of the sediment screening machine component group when in use.

[0014] 2. The sediment screening machine for a water conservancy project is provided with a dust-proof component group. The current sediment screening machine lacks a dust-proof mechanism. In actual use, the high-frequency vibration of the sediment will cause a large amount of dust, affecting the health of people around the construction environment. In the corresponding designed dust-proof component group, the sediment enters the sediment screening machine component group through the feed port, and the sediment screening machine component group vibrates and screens the sediment. The dust generated by the sediment will be blocked inside by the dust-proof outer shell. After turning on the fan assembly, the fan assembly will discharge the dust in the dust-proof outer shell to the outside through the dust exhaust pipe, and the dust-proof curtain is connected to the dust-proof outer shell. The dust-proof curtain can block the dust, but will not affect the discharge of sediment by the sediment screening machine component group. The design of this dust-proof component group can effectively discharge the dust in the dust-proof component group structure to the outside through the fan assembly and the dust exhaust pipe. The dust exhaust pipe can be connected to a dust reduction or dust collection device, thereby reducing the impact of a large amount of dust on the health of people around.
