Technical Field

[0001] The utility model relates to the field of water conservancy construction, in particular to a dredging device for water conservancy construction. Background Technique

[0002] Dredging in water conservancy construction refers to the process of removing the silt, sediment and other deposits deposited at the bottom of rivers, lakes, reservoirs and channels. These deposits will gradually accumulate over time, affecting the water volume, water quality and water flow condition of the water body, and may even increase the flood risk.

[0003] The existing dredging devices for water conservancy construction usually crush the silt through the crushing drum on the cleaning vehicle and then collect and process it. However, since the current cleaning vehicle is not convenient for centralized treatment of more silt, and when the silt is in a dry or difficult-to-clean state, it is not convenient to clean the silt faster, thus affecting the dredging efficiency. And after the cleaning is completed, it is usually necessary to clean the crushing drum through other cleaning devices additionally, and the crushing drum cannot be cleaned at any time, so the use is not convenient enough.

[0004] Therefore, it is necessary to design a dredging device for water conservancy construction that can conveniently clean the crushing drum and humidify the silt, and can centrally process more silt through an expander, facilitating faster cleaning of the silt, with convenient use and improved dredging efficiency.

However, the present utility model can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the present utility model to those skilled in the art.

[0021] A dredging device for water conservancy construction, as Figures 1 - 3 shown, comprising a locomotive 1, an expander 2, a first motor 3, a crushing drum 4, an interception net 5, a crawler wheel 6, a sludge discharge pipe 7, a cleaning mechanism 8 and a sprinkling mechanism 9. Two expanders 2 are rotatably connected to the right part of the locomotive 1, a first motor 3 is connected to the right front part of the locomotive 1, a crushing drum 4 is connected to the output shaft of the first motor 3, the crushing drum 4 is rotatably connected to the locomotive 1, an interception net 5 is connected to the right part of the locomotive 1, the interception net 5 is located on the left of the expander 2, crawler wheels 6 are provided at both the front and rear parts of the locomotive 1, a sludge discharge pipe 7 is connected to the front side of the upper part of the locomotive 1, a cleaning mechanism 8 capable of cleaning the ground is provided on the left part of the locomotive 1, and a sprinkling mechanism 9 capable of conveniently cleaning the crushing drum 4 and humidifying the sludge is provided on the upper part of the locomotive 1.

[0022] As Figure 1 , Figure 2 and Figure 4 shown, the cleaning mechanism 8 comprises a roller brush 81, a baffle frame 82, a lead screw 83 and a second motor 84. Two second motors 84 are connected to the upper left part of the locomotive 1, the output shafts of the second motors 84 are both connected with lead screws 83, the lead screws 83 are both rotatably connected to the locomotive 1, and a baffle frame 82 is threadedly connected between the lead screws 83. The baffle frame 82 is in a folded shape for convenient shielding, and a roller brush 81 is rotatably connected to the lower part of the baffle frame 82.

[0023] As Figure 1 , Figure 2 and Figure 5 shown, it further comprises a sprinkling mechanism 9, and the sprinkling mechanism 9 comprises a water storage tank 91, a lid 92 and a nozzle 93. The water storage tank 91 is connected to the upper right part of the locomotive 1, the lid 92 is snap-connected to the front side of the right part of the water storage tank 91, and the nozzle 93 is connected to the right side of the water storage tank 91 through a water pump.

[0024] When using this device, first move the locomotive 1 to the dredging area of water conservancy construction through the crawler wheels 6, then control the expander 2 to open through the locomotive 1, and then the crawler wheels 6 drive the locomotive 1 to move. At the same time, start the first motor 3 to drive the crushing roller 4 to rotate, so that a large amount of silt enters the locomotive 1 through the opening of the expander 2. The silt is crushed by the rotation of the crushing roller 4, and larger debris is intercepted by the interception net 5, so that the crushed silt is discharged into the interior of the locomotive 1. When the silt is relatively dry, the water pump can be started to make water discharge from the nozzle 93 through the water storage tank 91, so that the water is sprayed onto the crushing roller 4 and the silt to humidify the crushing roller 4 and the silt. After the silt cleaning is completed, the water can also be sprayed out through the nozzle 93 to directly clean the crushing roller 4, so that it is convenient to clean the crushing roller 4 and humidify the silt, and more silt can be centrally processed through the expander 2, which is convenient to clean the silt faster, with convenient use and improved dredging efficiency. When the water volume in the water storage tank 91 is insufficient, the lid 92 can be removed and then water can be injected into the water storage tank 91. While the locomotive 1 is moving, the second motor 84 can be started to drive the lead screw 83 to rotate, so that the baffle frame 82 moves downward under the action of the thread, driving the roller brush 81 to move downward, so that the roller brush 81 contacts the ground where the silt has been cleaned. Then, the locomotive 1 moves to drive the roller brush 81 to rotate, and the ground is cleaned by the roller brush 81, so that the ground can be cleaned during the dredging process, reducing the subsequent cleaning time and improving the construction efficiency. After the cleaning is completed, the silt is pumped out through the sludge discharge pipe 7 connected to an external pump body.
