Technical Field

[0001] The utility model relates to the technical field of river and lake dredging, in particular to a double-row roller type environmental protection cutter head. Background Art

[0002] River and lake dredging is an essential part of water environment treatment and water transportation construction. It is an important underwater earthwork excavation project. Through specific machinery, soil and rock materials such as silt, gravel, and rock at the bottom of rivers, lakes, and waters are excavated and transported to a designated area. Due to its high efficiency, safety, continuous operation ability, and good adaptability, the cutter suction dredger has been widely used as an efficient dredging engineering equipment in port and waterway construction, seawall and beach filling, and marine environment restoration.

[0003] During the dredging process, the dredger first uses a rotating cutter head to break the river and lake bottom mud, making the bottom mud mix with the water to form slurry, and then sucks the underwater slurry into the dredger to complete the dredging. In the prior art, the cutter head has high water depth requirements and a small stirring area, which affects the cutter suction efficiency, resulting in corresponding limitations during the use of the equipment. Moreover, the bottom mud is prone to spread during the construction process, causing water pollution. Therefore, further improvement is needed. Summary of the Utility Model

[0022] As shown in the figure, the present utility model includes a cover body 1, two sets of cutter body 3 rotatably connected inside the cover body 1, a mud suction pipe 4 communicated with the cover body 1, and a driving assembly connected to the cutter body 3. A dredging space for dredging and sucking mud is provided inside the cover body 1, and the lower end and the front and rear sides of the cover body 1 are all open. The two sets of cutter body 3 are arranged in parallel in the dredging space, and the two sets of cutter body 3 are linearly arranged along the front and rear directions of the cover body 1 and are driven to rotate by the driving assembly. The mud suction pipe 4 is communicated with the dredging space of the cover body 1. In this example, it is preferably that the end of the mud suction pipe 4 extending into the cover body 1 is located between the two sets of cutter body 3, and is used to be connected to a dredger to suck the mud stirred by the cutter body 3 to a designated area.

[0023] Among them, the cover body 1 includes a top plate and two side plates, and the cutter body 3 is rotatably connected between the two side plates. In addition, the cover body 1 further includes side cover plates 2 located on both sides of the top plate. An inclined surface 101 is provided on the upper side of the side plate, and the side cover plates 2 are installed between the inclined surfaces 101 of the two side plates. The setting of the side cover plates 2 can reduce the diffusion of sludge and is more environmentally friendly.

[0024] The reamer body 3 includes a roller 301 and a plurality of cutter bodies 302 mounted on the roller 301. The roller 301 is horizontally arranged. The reamer body 3 is rotationally connected to the cover body 1 through the roller 301. The cutter bodies 302 are uniformly arranged along the circumferential direction of the roller 301 (in this example, 4 cutter bodies 302 are arranged in each row in the circumferential direction), and are linearly spaced along the axial direction of the roller 301, which is beneficial to break the bottom mud of rivers and lakes more comprehensively, quickly and all-round. In this example, the cutter body 302 is preferably detachably connected to the roller 301. By setting the socket 305 for positioning, it is more convenient for the quick installation of the cutter body 302. Specifically, a cutter seat 303 is arranged on the roller 301. The number of cutter seats 303 is the same as that of the cutter bodies 302. The cutter seat 303 is provided with a socket 305. The cutter body 302 is inserted into the socket 305 and connected to the cutter seat 303. In this example, the cutter seat 303 is provided with a bolt hole 306, and the cutter body 302 is provided with a threaded hole. The locking bolt 304 is threadedly connected to the bolt hole 306 and the threaded hole.

[0025] Meanwhile, a support column 6 is arranged inside the cover body 1. The support column 6 supports the cover body 1 and improves the stiffness of the cover body 1. The support column 6 is of a hollow structure and is located between two groups of reamer bodies 3. A plurality of mud inlets are formed on the surface of the support column 6. The suction pipe 4 is communicated from the outside of the cover body 1 to the inside of the support column 6.

[0026] In addition, the drive assembly includes two drive motors 5 respectively connected to the reamer bodies 3. The drive motors 5 are installed outside the cover body 1. The rotation directions of the two groups of reamer bodies 3 are opposite, which can make the bottom mud broken by the two groups of reamer bodies 3 mix better between the two groups of reamer bodies 3 to form a higher concentration of slurry.

[0027] Compared with the prior art, the utility model is provided with a cover body. The lower end, the front side and the rear side of the cover body are all open, and a dredging and suction space is arranged inside the cover body. Two groups of reamer bodies are rotatably arranged in the dredging and suction space of the cover body. The two groups of reamer bodies are linearly arranged along the front and rear directions of the cover body. The reamer body is provided with a roller. The rollers of the two groups of reamer bodies are all horizontally arranged and parallel to each other. Thus, the two groups of parallel reamer bodies can break and cut the bottom mud of rivers and lakes over a larger area. At the same time, under the rotation of the two groups of reamer bodies, the broken bottom mud can be mixed between the two groups of reamer bodies to form a high-concentration slurry. Then, the suction pipe located between the two groups of reamer bodies and connected to the pump body on the dredger pumps the high-concentration slurry to the designated area. By arranging two groups of parallel reamer bodies and reasonably arranging the suction pipe, the utility model increases the operation area, improves the flatness of the operation surface and the dredging and suction efficiency, and the cover body can effectively reduce the diffusion of the slurry during the dredging process.

[0028] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
