A mounting ring 5 is installed inside the suction hood 1 through the disassembly assembly 7, and a filter screen 6 is fixedly connected inside the mounting ring 5. During operation, the connection between the external suction equipment and the suction hood 1 can enable the suction hood 1 to suck and dredge the silt inside the river channel, and some larger impurities can be filtered through the filter screen 6 during suction, and avoid affecting the external suction equipment. Then, during suction, the suction hood 1 is connected and moved by the external lifting equipment, and is convenient to move through the universal wheels 3, and during suction, the larger silt is crushed by the crushing assembly 2, thereby avoiding blockage caused by the large sucked silt and avoiding affecting the use of the equipment. At the same time, the disassembly assembly 7 facilitates the disconnection of the mounting ring 5 from the suction hood 1, thereby facilitating the disassembly, maintenance and replacement of the mounting ring 5 and the filter screen 6, and enables the equipment to meet more usage requirements and has strong practicality.

[0030] The top of the suction hood 1 is fixedly connected to a connecting pipe 4; when working, the connection and installation of the external suction device and the device are facilitated by connecting the suction pipe of the external suction device to the connecting pipe 4.

[0031] A plurality of evenly distributed lifting rings 8 are fixedly connected to the top of the suction hood 1; when in operation, the external lifting equipment is conveniently connected and installed to the equipment through the connection and installation of the external ropes and the lifting rings 8.

[0033] The disassembly component 7 includes a plurality of evenly distributed through slots 705 opened inside the suction hood 1, a rod 704 is slidably inserted into the through slot 705, one end of the rod 704 is fixedly connected to an extrusion block 703, the outer surface of the rod 704 is located inside the through slot 705 and a spring 706 is sleeved thereon, one end of the spring 706 is fixedly connected to the outer surface of the rod 704, and the other end of the spring 706 is fixedly connected to the inner wall of the through slot 705. The jacks 707 are evenly distributed, and the other end of the insertion rod 704 is inserted into the jacks 707. A handle 701 is provided above the outer surface of the suction hood 1. A continuous inner groove 702 is provided inside the handle 701, and the extrusion block 703 is inserted into the inner groove 702. A plurality of evenly distributed card slots 708 are provided inside the inner groove 702. When working, when it is necessary to disassemble the mounting ring 5 and the filter screen 6 inside it, the handle 701 is first rotated so that the handle 701 drives the card slot 708 and the card block When the clamping block and the clamping slot 708 are aligned, the rebound force of the originally squeezed spring 706 drives the insertion rod 704 and the extrusion block 703 to move, and then the extrusion block 703 is clamped inside the clamping slot 708, and the insertion rod 704 is moved out from the insertion hole 707 on the outer surface of the mounting ring 5, so that the insertion rod 704 can be separated from the limit installation of the mounting ring 5, and the mounting ring 5 can be separated from the connection with the suction hood 1, thereby facilitating the disassembly, maintenance and replacement of the mounting ring 5 and the filter screen 6, and making the device meet more usage requirements. The demand is met and it is more practical. At the same time, when installing, the mounting ring 5 is inserted into the inside of the suction hood 1 and corresponds to the insertion rod 704, and then the handle ring 701 is rotated so that the block inside the card slot 708 is squeezed and drives the insertion rod 704 to move and be inserted into the inside of the socket 707 to limit the mounting ring 5. The position of the handle ring 701 is kept inconvenient so that the mounting ring 5 can be installed firmly, and the handle ring 701 can be rotated so that the block is farther away from the position of the card slot 708, so that the ring 701 can be rotated at all without causing the block to move.

[0034] The extrusion block 703 is movably connected to one end of the insertion rod 704 and the inner groove 702; when working, it is convenient to rotate the handle 701 so that the extrusion block 703 and the insertion rod 704 are moved and inserted into the slot 708.
