Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of silt clearing and dredging equipment, in particular to a silt clearing and dredging device. Background Art
[0002] In the work of channel and river regulation and management, it is necessary to dredge the silt on the riverbed to ensure the ecological environment of the river and avoid pollution. At present, there are generally two ways of dredging and dredging. One is to use a stirring and blowing device to blow the silt deposited on the riverbed into turbid water, and the silt flows away with the river water, thereby playing a dredging role. The other is to use a suction device to extract the silt and sewage, and then achieve the purpose of river management. The two treatment methods are suitable for different river environments.
[0003] When silt and sewage are treated by suction, sand and gravel on the riverbed are often pumped out. These stones often have a certain impact on the equipment and may even cause blockage and damage. Secondly, when silt and sewage are extracted, the silt cannot be crushed before extraction because the sewage pipe directly extracts the silt. Extracting the entire piece is prone to blockage, which is not conducive to the sustainable cleaning of the silt. There are certain defects and deficiencies, so improvements are needed. Utility Model Content
[0004] 1. Technical issues to be resolved
[0005] In view of the shortcomings of the prior art, the utility model provides a silt clearing and dredging device, in which a protective cover is arranged at the end of the dredging pipe, silt and sewage enter the dredging pipe through the drainage hole on the protective cover, and a protective component is installed on the protective cover. When the silt and sewage are extracted, the fan blades in the protective component drive the shaft to rotate, so that the arc-shaped processing plate rotates. The arc-shaped processing plate can clean the sand and gravel outside the protective cover on the one hand, and can crush the silt on the other hand, making it easier for the device to extract silt, thereby solving the problem that the current device is easy to be blocked and has low safety when working.
[0006] (II) Technical solution
[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:
[0008] A dredging device comprises a dredging pipe, one end of which is fixedly connected to a protective cover, the protective cover is provided with sewage discharge holes distributed in an array, and a protective component is installed on the protective cover, the protective component comprises a shaft rod rotatably connected to the center of the protective cover, one side of the shaft rod is fixedly connected to two arc-shaped processing plates, the two arc-shaped processing plates are both attached to the outside of the protective cover, and one side of the shaft rod is also fixed with a plurality of inclined fan blades, and the fan blades are located on the inner side of the dredging pipe.
[0009] Furthermore, a bearing is provided at the connection between the shaft rod and the protective cover.
[0010] Furthermore, the dredging pipe and the protective cover are connected and fixed by means of a connecting flange, two connecting flanges are provided, bolts are fixed between the two connecting flanges, and a sealing gasket is provided at the connection between the two connecting flanges.
[0011] Furthermore, a pipe connector arranged at one end of the dredging pipe away from the protective cover is connected to a sewage extraction hose.
[0012] (III) Beneficial effects
[0013] Compared with the prior art, the utility model provides a dredging device, which has the following beneficial effects:
[0014] The utility model provides a dredging pipe, a protective cover and a protective component, wherein the protective cover is installed at the end of the dredging pipe to protect the end of the dredging pipe and prevent large pieces of sand and debris from entering. Silt and sewage enter through the sewage discharge hole arranged on the protective cover. The protective component is installed at the center of the protective cover. The protective component consists of a shaft rod rotatably connected to the protective cover, and an arc-shaped processing plate and fan blades fixed on the shaft rod. When the silt and sewage enter the interior of the dredging pipe, the fan blades can be driven to rotate by the action of water flow, thereby rotating the shaft rod and the arc-shaped processing plate. When the arc-shaped processing plate rotates, on the one hand, stones and foreign objects outside the protective cover can be cleaned to avoid clogging the sewage discharge hole. Secondly, the silt outside the protective cover can be crushed and refined, so that the external silt can enter the protective cover more easily to avoid clogging. The entire extraction process is more stable, so that the dredging treatment of the silt can be carried out normally. BRIEF DESCRIPTION OF THE DRAWINGS
