The working principle of the second telescopic rod 15 is that the piston rod 151 adjusts the angle of the guide plate 13 according to the size of the water flow under the elastic action of the first spring 152, and the structural composition of the first telescopic rod 14 is consistent with that of the second telescopic rod 15, which will not be described in detail here.
[0035] Example 2
[0036] This embodiment 2 is implemented on the basis of embodiment 1, and movable grooves 44 are provided on both sides of the sludge box 4, the movable groove 44 on the left side is higher than the movable groove 44 on the right side, and an inclined plate 47 is installed between the movable grooves 44, and the inclined plate 47 in a low position is connected to the mud discharge pipe 41. Both ends of the inclined plate 47 are provided with protrusions 45, and the protrusions 45 are located in the movable grooves 44. A second spring 46 is provided below the protrusions 45, and a vibration motor 48 is provided below the inclined plate 47.
[0037] Reference Figure 3 In this application, two movable grooves 44 with different heights are provided with inclined plates 47, and protrusions 45 at both ends of the inclined plates 47 are inserted into the movable grooves 44. At the same time, a second spring 46 is provided below the protrusions 45 to provide elastic buffering. Mainly driven by a vibration motor 48, the inclined plates 47 move up and down in the movable grooves 44, and the second spring 46 provides elastic support and buffering for it, so that the sludge above the inclined plates 47 shakes and is discharged from the sludge discharge pipe 41. The sludge is discharged mainly after the upper water is discharged.
[0038] In some preferred embodiments, a hydraulic rod 42 is provided on the top of the sludge box 4, and a telescopic water pipe 43 is provided at the telescopic end of the hydraulic rod 42, and the end of the telescopic water pipe 43 away from the hydraulic rod 42 is connected to the drainage pipe 40. A pressure pump 400 is provided in the drainage pipe 40.
[0039] The hydraulic rod 42 provided on the top of the sludge box 4 moves the entrance of the telescopic water pipe 43 to the top of the sludge sediment. Under the action of the pressure pump 400, the water without sludge is discharged from the telescopic water pipe 43 through the drain pipe 40 for irrigation. Due to the effect of gravity, the sludge enters the sludge box 4 and will settle to the bottom of the sludge box 4, forming a stratification phenomenon with the water. During the drainage process, the sludge will not enter the telescopic drain pipe 40.
[0040] When the utility model is used, the device is connected to an external controller to start the dredging work. First, the interface 10 is opened to connect the water conservancy channel with the water inlet pipe 1, and the weeds and silt in the channel will enter the water inlet pipe 1. The guide plate 13 blocks the weeds and silt for the first time to prevent them from entering the water inlet pipe 1 in large quantities. The stirring rod 16 and the saw teeth on its periphery block the weeds and sludge crushing process for the second time. After passing through the filter screen 2, a small amount of silt and water enter the sludge box 4 through the discharge hopper 12 to produce stratification. The upper layer of water is drained through the retractable water pipe 43 and the drainage pipe 40 for flooding. After the upper layer of water is discharged, the vibration motor 48 causes the inclined plate 47 to shake, so that the silt on the inclined plate 47 is transferred from high to low and discharged through the mud discharge pipe 41. The guide plate 13 connected by the second telescopic rod 15 and the stirring rod 16 with pointed serrations provided in the utility model realize double blocking of weeds and silt. At the same time, the disassembly and assembly components 3 at both ends of the filter screen 2 realize the disassembly and assembly of the filter screen 2 and timely cleaning, thereby avoiding blockage of the silt clearing device. The telescopic water pipe 43 in the silt box 4 adapts to the water level of different layers so as to discharge in time, and the vibration motor 48 shakes the silt above the inclined plate 47 and discharges it to the sludge discharge pipe 41. The silt clearing effect is good, and there is no weed and silt blockage when using channel water for flooding, and the flooding efficiency is high.
[0041] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
