DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5A river channel silt excavation device comprises an excavation component 1 and a mounting rod 2. The bottom of the mounting rod 2 is provided with an installation cavity 21. The excavation component 1 is adapted to be assembled in the installation cavity 21. A limit block 5 is fixedly provided on the top of the excavation component 1, and a limit cavity 22 is adapted to be provided at the top of the installation cavity 21 corresponding to the limit block 5. The bottom of the excavation component 1 is inclined. An excavation cavity 11 is upwardly provided at the bottom of the excavation component 1. A fixing plate 12 is fixedly provided in the excavation cavity 11. A driving motor 13 is installed on the top of the fixing plate 12. The output end of the driving motor 13 passes downward through the fixing plate 12 and is connected to the auger 14 in a transmission manner. The assembly of the device can be realized by assembling the excavation component 1 on the mounting rod 2.

[0021] Among them, the installation rod 2 is connected to one side of the limit cavity 22 and is provided with an adjustment cavity 23, and a movable block 4 is movably provided in the adjustment cavity 23. The limit block 5 is eccentrically arranged at the top of the excavation assembly 1, and a limit groove 51 is provided inwardly on one side of the limit block 5, and the limit groove 51 is adapted to the movable block 4 in the adjustment cavity 23. By setting the movable block 4, the limit groove 51 can be clamped, so that the limit block 5 can be fixed.

[0022] Among them, a connecting column 41 is fixedly and vertically arranged at one end of the movable block 4 away from the limiting block 5, and the connecting column 41 extends from the mounting rod 2. An anti-dropping piece 42 is fixedly arranged at one end of the connecting column 41 extending from the mounting rod 2, and an outer cavity 3 is provided on the outer side of the mounting rod 2 corresponding to the anti-dropping piece 42. By setting the connecting column 41, the position of the movable block 4 can be adjusted. And by setting the anti-dropping piece 42, the movable block 4 can be prevented from moving into the mounting cavity 21 and falling off.

[0023] Among them, an N-pole magnetic block is arranged on one end of the movable block 4 facing the limit block 5, and an S-pole magnetic block is adapted to the inner wall of the limit slot 51. In this way, the movable block 4 can be adsorbed in the limit slot 51 by the magnetic attraction between the magnetic blocks, thereby preventing the movable block 4 from loosening and falling off during the clamping process.

[0024] In this embodiment, the excavation assembly 1 can be used to excavate the silt in the river channel. When the excavation assembly 1 is used, the excavation assembly 1 needs to be assembled on the mounting rod 2. There are multiple mounting rods 2, and their lengths are different. The user can assemble the excavation assembly 1 on the mounting rods 2 of different lengths to excavate the silt in the river channel of different depths.

[0025] Furthermore, when assembling the excavating assembly 1, the user only needs to insert the top of the excavating assembly 1 into the mounting cavity 21 provided at the bottom of the mounting rod 2. At this time, the stop block 5 on the excavating assembly 1 can automatically enter the stop cavity 22, and the stop groove 51 on the stop block 5 is also aligned with the adjustment cavity 23.

[0026] Furthermore, since one end of the movable block 4 is an N-pole magnetic block and the inner wall of the limiting groove 51 is an S-pole magnetic material, the movable block 4 will automatically move into the limiting groove 51 due to the magnetic attraction force, so that the installation between the excavating component 1 and the mounting rod 2 can be achieved through the clamping between the movable block 4 and the limiting groove 51. And when the user needs to disassemble the device, he only needs to pull the anti-dropping member 42 on the outer cavity 3 outward, so that the movable block 4 can be driven to leave the limiting groove 51 through the connecting column 41, thereby realizing the disassembly between the excavating component 1 and the mounting rod 2.

[0027] Furthermore, when the user needs to excavate and sample the silt at the bottom of the river, he only needs to move the excavation assembly 1 downward through the mounting rod 2, and drive the auger 14 to rotate through the drive motor 13. When the excavation assembly 1 moves to the silt inside the river, the silt enters the excavation cavity 11, and the river silt can be collected through the rotation of the auger 14. It is also worth noting that a battery is provided inside the excavation assembly 1 above the drive motor 13, and the drive motor 13 can be powered by the battery, and the user can charge the battery after the excavation sampling task is completed.

[0028] In the utility model, the collection of river silt can be achieved through the excavation component 1, and through the adaptation setting between the movable block 4 and the limit block 5, not only can the device be conveniently assembled and carried, but also the excavation component 1 can be assembled on the mounting rod 2 of different lengths to adapt to operations on rivers of different depths, which is convenient for use by staff.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
