Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0022] Please refer to Figures 1-5 , an embodiment provided by the present utility model:
[0023] A dredging machine for civil engineering and water conservancy construction, including a hull 1. A sewage collection tank 2 is fixedly connected to the top of the hull 1. An adjustment structure 3 is arranged on the top of the hull 1. The adjustment structure 3 includes a housing 31. A motor 32 is fixedly connected to the inside of the housing 31. The output end of the motor 32 is fixedly connected with a gear. The gear meshes with a chain 33 through the teeth on its surface. One end of the chain 33 is fixedly connected with a counterweight 34. The other end of the chain 33 is fixedly connected with a fixing plate 35. A limiting block 36 is fixedly connected to the surface of the fixing plate 35. A sewage cleaning structure 4 is arranged on the surface of the fixing plate 35. The sewage cleaning structure 4 includes a sewage pump 41. A sewage suction pipe 42 is fixedly connected to the bottom of the sewage pump 41. A sewage suction port 43 is fixedly connected to the surface of the sewage suction pipe 42. A protective net 44 is fixedly connected to the bottom of the sewage suction port 43. A support column 45 is fixedly connected to the surface of the sewage pump 41. A fixing rod 46 is fixedly connected to the surface of the protective net 44. A blade 47 is arranged on the surface of the fixing rod 46. The output end of the sewage pump 41 is fixedly connected with a delivery hose 5. The adjustment structure 3 is provided. The motor 32 rotates to drive the gear on the output end to rotate. The gear meshes with the chain 33 to drive the chain 33 to move. The counterweight 34 at one end of the chain 33 is used to cooperate to pull the fixing plate 35 at the other end of the chain 33 to move up and down, so as to adjust the height of the sewage cleaning structure 4 on the fixing plate 35, making it adaptable to different heights and being more convenient to use. The blade 47 and the protective net 44 are provided. The blade 47 arranged at the sewage suction port 43 of the sewage cleaning structure 4 can disperse large pieces of silt when extracting silt, preventing the large pieces of silt from jamming the sewage suction port 43. The protective net 44 is placed outside the blade 47 to prevent the blade 47 from directly contacting the river bottom surface when adjusting the height of the sewage cleaning structure 4, causing damage to the blade 47.
[0024] Further, one end of the delivery hose 5 is fixedly connected to the output end of the sewage pump 41, and the other end of the delivery hose 5 is fixedly connected to the top of the sewage collection tank 2. The sewage pump 41 is used to extract the silt at the bottom of the river into the sewage collection tank 2 for precipitation.
[0025] Further, the housing 31 is fixedly connected to the upper surface of the hull 1. Two groups of sliding grooves are opened on both sides of the housing 31. The cross section of the limiting block 36 is T-shaped. The limiting block 36 passes through the housing 31 through the sliding groove, and the limiting block 36 is slidably connected in the sliding groove. The cooperation between the limiting block 36 and the sliding groove enables the fixing plate 35 to move only in the up and down directions.
[0026] Further, a cavity is opened inside the housing 31. The motor 32, the chain 33 and the counterweight 34 are all arranged in the cavity. The motor 32 is fixedly connected to the inner wall of the cavity. The motor 32 drives the chain 33 to move, and cooperates with the counterweight 34 to drive the fixing plate 35 at the other end of the chain 33 to move up and down.
[0027] Further, a square groove is formed in the middle of two groups of sliding grooves on the outer shell 31. One end of the chain 33 connected to the fixing plate 35 is slidably connected in the square groove. When the chain 33 drives the fixing plate 35 to move, the end of the chain 33 connected to the fixing plate 35 slides up and down through the square groove.
[0028] Further, engaging plates are fixedly connected to the surfaces of the sewage extraction port 43 and the sewage extraction pipe 42. One end of the support column 45 is fixedly connected to the surface of the sewage pump 41, and the other end of the support column 45 penetrates through the engaging plate and is engaged with it. The support column 45 provides a certain supporting force for the sewage extraction pipe 42.
[0029] Further, the radius of the protective net 44 is greater than the rotation radius of the blade 47. The blade 47 is arranged inside the protective net 44. The protective net 44 provides a certain protection for the blade 47 to prevent the blade 47 from directly contacting the bottom of the river when adjusting the height of the sewage cleaning structure 4, causing damage to the blade 47.
[0030] Working principle: When in use, first transport the hull 1 to the area to be cleaned. Rotate the motor 32 to drive the gear on the output end to rotate. Drive the chain 33 to move through the meshing of the gear and the chain 33. Cooperate with the counterweight 34 at one end of the chain 33 to pull the fixing plate 35 at the other end of the chain 33 to move up and down, so as to adjust the height of the sewage cleaning structure 4 on the fixing plate 35, making it adaptable to river bottoms of different heights. Turn on the sewage pump 41 to suck the silt on the river bottom. The silt enters the sewage extraction pipe 42 through the sewage extraction port 43 and then enters the sewage collection tank 2 through the conveying hose 5 for collection and precipitation. A blade 47 is arranged at the bottom of the sewage extraction port 43. When encountering larger pieces of silt, the blade 47 can be used to break up the silt to make the suction of the sewage pump 41 smoother and prevent the sewage pump 41 and the sewage extraction port 43 from being blocked. A protective net 44 is installed outside the blade 47 to prevent the blade 47 from directly contacting the river bottom when adjusting the height of the sewage cleaning structure 4, causing damage to the blade 47.
[0031] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, in any regard, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be regarded as limiting the claimed rights.
