[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , Figure 2 As shown, a slope excavation device for a cutter suction dredger includes: an operating end 1 and a control lever 2 on the cutter suction dredger, and further includes: a slide rail 3 fixed to the side wall of the control lever 2; a moving mechanism 4 slidably connected to the slide rail 3; a support boom 5 rotatably connected to the moving mechanism 4; an angle adjustment frame 6 rotatably connected to the end of the support boom 5; and a slope straightening plate 7 fixed to the end of the angle adjustment frame 6.

[0023] Both the operating end head 1 and the control lever 2 are existing components of the cutter suction dredger. The operating end head 1 excavates the bottom mud by rotating, so that the slope is basically formed. The control lever 2 is located at the rear end of the operating end head 1 and is connected to the dredger. The dredger controls the height and angle of the control lever 2 and the operating end head 1. The operating end head 1 can collect the excavated bottom mud into the control lever 2 and discharge it from the rear end of the dredger.

[0024] The moving mechanism 4 changes the position of the slope slab 7 by moving back and forth to prevent the slope slab 7 from conflicting with the operating end 1 and affecting the slope excavation. The moving mechanism 4 includes a moving frame 41, a force-bearing frame 42, a fixed frame 43, and a first electric telescopic rod 44. The moving frame 41 is slidably connected to the bottom of the slide 3. The bottom of the force-bearing frame 42 passes through the slide 3 and is fixedly connected to the moving frame 41. The force-bearing frame 42 restricts the moving frame 41 from detaching from the slide 3 due to gravity. The fixed frame 43 is located at the top rear end of the slide 3 and is also behind the force-bearing frame 42. The two ends of the first electric telescopic rod 44 are respectively connected to the force-bearing frame 42 and the fixed frame 43. The fixed end of the first electric telescopic rod 44 is fixedly connected to the moving frame 41, and the telescopic end of the first electric telescopic rod 44 is fixedly connected to the force-bearing frame 42. The first electric telescopic rod 44 drives the force-bearing frame 42 and the moving frame 41 to move back and forth along the slide 3 by telescopic movement.

[0025] The movable frame 41 surrounds the lower part of the control lever 2, while the fixed frame 43 and the force-bearing frame 42 surround the upper part of the control lever 2. The movable frame 41 and the force-bearing frame 42 will not interfere with the control lever 2 when they move. At the same time, the movable frame 41 and the fixed frame 43 add a layer of protection to the control lever 2, preventing minor impacts.

[0026] The rear end of the supporting boom 5 has two forks 51. A first rotating shaft 411 is provided on the side wall of the moving frame 41. The forks 51 are rotatably connected to the first rotating shaft 411. A first angle sensor 412 is provided on the first rotating shaft 411. The first angle sensor 412 can record the rotation angle of the forks 51 in real time and transmit it to the control room of the dredger, thus allowing the operator to know the tilt angle of the supporting boom 5 in real time. There is a distance between the two forks 51, which is greater than the diameter of the operating end 1, so that the forks 51 will not collide with the sides of the operating end 1 during rotation and up-and-down movement.

[0027] The fixed end of the second electric telescopic rod 52 is rotatably connected to the side wall of the movable frame 41, and the telescopic end of the second electric telescopic rod 52 is rotatably connected to the inner wall of the fork 51. The second electric telescopic rod 52 changes the rotation angle of the support arm 5 by telescoping. When the telescopic end of the second electric telescopic rod 52 extends, the support arm 5 rotates upward; when the second electric telescopic rod 52 retracts, the support arm 5 rotates downward.

[0028] The rear end of the angle adjustment frame 6 is a connecting seat 61, and the front end of the support arm 5 is provided with a second rotating shaft 53. The second rotating shaft 53 is rotatably connected to the connecting seat 61. A second angle sensor 54 is provided on the second rotating shaft 53. The second angle sensor 54 transmits the rotation angle information of the angle adjustment frame 6 to the control room. The monitoring personnel can know the angle of the slope plate 7 through the first angle sensor 412 and the second angle sensor 54, which facilitates the adjustment of the slope inclination angle when excavating the slope.

[0029] The information transmission methods of the first angle sensor 412 and the second angle sensor 54 both adopt existing technologies.

[0030] The front end of the supporting boom 5 is rotatably connected to the fixed end of the third electric telescopic rod 62. The telescopic end of the third electric telescopic rod 62 is rotatably connected to the rear end of the connecting seat 61. When the third electric telescopic rod 62 retracts, it causes the angle adjusting frame 6 to tilt upward. When the third electric telescopic rod 62 extends, it causes the angle adjusting frame 6 to tilt downward. When the angle adjusting frame 6 tilts, it causes the slope plate 7 to tilt together, thus facilitating the adaptation to the angle of slope excavation.

[0031] The front end of the angle adjustment frame 6 is provided with a support frame 63, which is fixed to the rear end of the slope plate 7. The support frame 63 drives the slope plate 7 to move.

[0032] The slope leveling plate 7 is a rectangular plate, with leveling wheels 71 rotatably connected to both ends. During slope excavation, the operating end 1 is used in conjunction with the movement of the dredger to excavate the approximate shape of the slope and remove excess bottom mud. Then, the slope leveling plate 7 is adjusted to the preset angle of the slope and placed on the slope excavated by the operating end 1. The dredger moves to press the slope leveling plate 7 against the slope surface and moves left and right to make the leveling wheels 71 roll, thus compacting and leveling the loose bottom mud on the slope surface and reducing the loss of soil on the slope surface after excavation.

[0033] A vibration motor 72 is fixedly connected to the rear end of the slope slab 7. When the slope slab 7 moves on the slope, the vibration motor 72 is started, which causes the slope slab 7 to vibrate, thereby improving the compaction efficiency.

[0034] All parts of this device are waterproofed to prevent leakage or rusting underwater.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
