At this time, the staff pulls the pull rod 34 to drive the support plate 20 to compress the first spring 25 and move away from the collection box 4, thereby reducing the possibility of the support plate 20 hindering the movement of the collection box 4.

[0049] like Figure 4 As shown, a first reset groove 35 is provided on the inner wall of the storage groove 32, and the first reset groove 35 extends in the horizontal direction.

[0050] like Figure 4As shown, in the process of collecting box 4 entering salvage opening 7, when the side wall of collecting box 4 pushes the left end of pushing block 28 to move rightward, pushing block 28 moves and drives first reset block 36 to compress second spring 37 and move rightward, and the movement of pushing block 28 drives resisting block 29 to move upward, and when resisting block 29 moves and drives plugging rod 30 to move upward, second reset block 39 follows plugging rod 30 to move upward and stretch third spring 40; when the staff cleans the silt in collecting box 4, the staff pulls pull rod 34 to make support plate 20 away from collecting box 4. At this time, first motor 8 starts to drive collecting box 4 to move downward, and when collecting box 4 is away from salvage opening 7, the side wall of collecting box 4 is away from the left end of pushing block 28, and the first reset block 36 is pushed and drives pushing block 28 to move leftward together by the elastic force of second spring 37, and the second reset block 39 drives plugging rod 30 to move downward together under the elastic force of third spring 40, so that the bottom end of plugging rod 30 can be inserted into slot 33 on support plate 20, thereby limiting the position of support plate 20.

[0051] like Figure 2 and Figure 5 As shown, the first motor 8 is located on the top side wall of the vehicle plate 1, the rotating shaft of the first motor 8 is fixedly connected to the top of the screw rod 5, the slider 42 is slidably connected to the guide rod 6 along the vertical direction, and the slider 42 is threadedly connected to the screw rod 5; the side walls at opposite ends of the collecting box 4 are fixedly welded with ear blocks 41, the ear blocks 41 are rectangular, and the opposite side walls of the two sliders 42 are provided with plug-in grooves 43 for inserting the ear blocks 41; the plug-in grooves 43 extend in the horizontal direction, the ear blocks 41 and the slider 42 are provided with plug-in holes 44, the plug-in holes 44 extend in the vertical direction, and the plug-in holes 44 are threadedly connected with bolts 45.

[0052] like Figure 2 and Figure 5 As shown, the ear block 41 on the collecting box 4 is fixedly connected to the slider 42 by bolts 45. When the silt in the collecting box 4 is full, the staff turns on the first motor 8, and the rotation of the first motor 8 drives the screw rod 5 to rotate. Under the action of the guide rod 6, the screw rod 5 rotates and drives the slider 42 to move along the axial direction of the screw rod 5. The movement of the slider 42 drives the ear block 41 to move, and the movement of the ear block 41 can drive the collecting box 4 to move to the salvage port 7; thereafter, the staff can tighten the bolt 45 until the bolt 45 is away from the ear block 41, the staff pulls the collecting box 4 to the right and takes away the collecting box 4, and then the staff needs to clean the silt in the collecting box 4; thereafter, the upper edge of the cleaned collecting box 4 is pushed horizontally to the left until the ear block 41 is inserted into the plug-in slot 43 on the slider 42, and the bolt 45 is used again to fix the ear block 41 and the slider 42, so that it is convenient for the staff to clean the silt in the collecting box 4.

[0053] The implementation principle of the embodiment of the present application is as follows: when the staff dredges the canal, the second motor 15 is turned on, the rotation shaft of the second motor 15 drives the worm 13 to rotate, and the rotation of the worm 13 drives the first turbine 14 and the second turbine 18 to rotate simultaneously, so that the crushing roller 10 and the conveying roller 17 rotate simultaneously, and the rotation of the crushing roller 10 drives the saw teeth 11 thereon to rotate, so as to break up the accumulated silt; the rotation of the conveying roller 17 can drive the conveyor belt 16 to move, and the broken silt enters the collecting box 4 under the conveyance of the conveyor belt 16, so as to improve the dredging work efficiency; the top of the dredging shovel 3 is provided with a blocking piece 24, which can push the silt adhering to the conveyor belt 16 into the collecting box 4;

[0054] When the silt in the collecting box 4 is full, the staff starts the first motor 8, and the first motor 8 drives the screw rod 5 to rotate, and the screw rod 5 rotates to drive the collecting box 4 to move downward to the salvage port 7. In the process of the collecting box 4 moving upward, the side wall of the collecting box 4 pushes the push block 28 to move rightward through the inclined surface 31 of the push block 28, and the push block 28 moves rightward and pushes the stop block 29 through the inclined surface 31 to drive the insertion rod 30 to move upward together, so that the insertion rod 30 is away from the slot 33 on the support plate 20. At this time, the support plate 20 moves to the left to the bottom of the collecting box 4 under the push of the first spring 25, and can hold up the collecting box 4. Subsequently, the staff screws the bolt 45 on the slider 42 until the bolt 45 is away from the ear block 41, and then the staff pulls out the collecting box 4 and cleans the silt inside.

[0055] Afterwards, the staff fixes the cleaned collection box 4 with the bolt 45 and the slider 42 again, and the staff pulls the pull rod 34 to the right until the support plate 20 is away from the collection box 4, and the collection box 4 moves downward under the drive of the screw rod 5. When the collection box 4 is away from the push block 28, the first reset block 36 and the second reset block 39 respectively push the push block 28 to the left and push the insertion rod 30 downward under the action of the second spring 37 and the third spring 40, so that the insertion rod 30 is inserted into the slot 33 of the support plate 20 again, thereby fixing the position of the support plate 20.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
