Cross connecting mechanism for trailing suction dredger

Abstract

The utility model relates to the field of dredgers, discloses a cross-shaped connecting mechanism for a drag suction dredger, and aims to solve the problems that the conventional cross-shaped connecting mechanism is very easy to be wrapped by sundries such as aquatic plants and the like when moving in water for a long time, and the cross-shaped connecting mechanism cannot be easily damaged when the cross-shaped connecting mechanism is tightly wrapped. The cross-shaped connecting mechanism for the drag suction dredger solves the problem that the cross-shaped connecting mechanism is difficult to rotate due to the fact that a pure cross-shaped connecting mechanism is difficult to cut off sundries such as aquatic plants by means of rotating shearing force in the prior art, and comprises a dredge pipe and a hose communicated with the lower portion of the dredge pipe. When the second supporting frame rotates, the pushing mechanism is driven to rotate, and then the pushing mechanism is driven to move towards the outer side to cut off aquatic plants, when the pushing mechanism rotates, the reciprocating mechanism is driven to reciprocate, so that the aquatic plants are cut off more easily, and compared with the prior art, the aquatic plants are cut off more easily; therefore, the purpose of facilitating rotation of the cross-shaped connecting mechanism is achieved.

SPECIFIC IMPLEMENTATION SCHEMES

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5, the present utility model provides a technical solution: a cross-connection mechanism for a trailing suction hopper dredger, including a suction pipe 1, a flexible pipe 2 connected below the suction pipe 1, a first support frame 3 fixedly connected to the outside of the suction pipe 1, the connection mode between the suction pipe 1 and the first support frame 3 is a rotational connection, a second support frame 4 arranged below the first support frame 3, a pushing mechanism 5 is arranged inside the second support frame 4, and a reciprocating mechanism 6 is arranged on one side of the pushing mechanism 5;

[0022] The driving mechanism 5 includes a support plate 501 slidably connected above one side of the second support frame 4. A first groove 502 is provided inside the middle of the support plate 501. A first rotating rod 503 is fixedly connected above the inner side of the other side of the second support frame 4. The first rotating rod 503 is rotatably connected to the first support frame 3. First holes 504 are opened inside both sides of the support plate 501. The first groove 502 communicates with the first holes 504. A second rotating rod 505 is provided inside the first holes 504. A rotating disc 506 is provided inside the first groove 502. First guide grooves 507 and second guide grooves 508 are provided inside the outer side of the rotating disc 506. The first guide grooves 507 and the second guide grooves 508 communicate with each other. A first guide rod 509 is provided inside the second guide grooves 508. There are multiple second guide grooves 508. The outer appearance structure of the first guide grooves 507 is arc-shaped, and the second guide grooves 508 are equidistantly distributed outside the first guide grooves 507, and the outer appearance structure shape of the second guide grooves 508 is arc-shaped, so that when the first guide rod 509 moves inside the first guide grooves 507, it will not move outward, and when it moves inside the second guide grooves 508, it can move outward. A second hole 510 is provided inside the inner side of the rotating disc 506. A third hole 511 communicates with the inner wall of the second hole 510. A push plate 512 is provided inside the third hole 511. The push plate 512 is fixedly connected to the second rotating rod 505. The second rotating rod 505 is nested inside the second hole 510. One end of the first guide rod 509 close to the support plate 501 is fixedly connected to a push rod 513. Fourth holes 514 are provided inside the other two sides of the support plate 501, and the fourth holes 514 communicate with the first groove 502, and the fourth holes 514 communicate with the outer surface of the support plate 501. A cutter 515 is provided inside the fourth holes 514. The rotating disc 506 is rotatably connected to the support plate 501. The inner side surface of the third hole 511 fits with the outer side surface of the push plate 512, and the length of the push plate 512 is greater than the thickness of the rotating disc 506, so that the rotating disc 506 will not move out of the control range of the push plate 512. The outer side surface of the second rotating rod 505 fits with the inner side surface of the first holes 504, and the outer appearance structure shape of the second rotating rod 505 is cylindrical, so that the second rotating rod 505 will not shake when rotating inside the first holes 504. The outer side surface of the cutter 515 fits with the inner side surface of the fourth holes 514, so that the cutter 515 will not rotate when moving inside the fourth holes 514. The second rotating rod 505 is fixedly connected to the first support frame 3.

[0023] The reciprocating mechanism 6 includes a second guide rod 601 fixedly connected to the inside of the first hole 504. A third guide groove 602 is provided inside the second rotating rod 505. The second guide rod 601 is nested inside the third guide groove 602. The third guide grooves 602 are equidistantly distributed inside the second rotating rod 505, and the third guide grooves 602 communicate with each other. Moreover, the top-down appearance structure of the third guide groove 602 is in a "V" shape, so that when the second guide rod 601 rotates, it can drive the support plate 501 to perform reciprocating motion. There are multiple third guide grooves 602.

[0024] When the external power source drives the second support frame 4 to rotate, it drives the support plate 501 to rotate, so that the cutter 515 and the push rod 513 rotate. Since the connection mode between the second rotating rod 505 and the first support frame 3 is a fixed connection, the second rotating rod 505 will not rotate, so that the rotating disk 506 and the push plate 512 will not rotate either. Since the appearance structure of the first guide groove 507 is arc-shaped, and the second guide grooves 508 are equidistantly distributed outside the first guide groove 507, and the appearance structure of the second guide groove 508 is arc-shaped. Due to the non-rotation of the second rotating rod 505 and the non-rotation of the rotating disk 506, the cutter 515 and the first guide rod 509 rotate following the support plate 501. There is relative movement between the first guide rod 509 and the rotating disk 506. When the first guide rod 509 moves to the inside of the second guide groove 508, the cutter 515, the first guide rod 509 and the push rod 513 move outward, separating the aquatic plants and other sundries wrapped outside the first support frame 3 and the second support frame 4, making it convenient for the first support frame 3 and the second support frame 4 to rotate.

[0025] When the support plate 501 rotates, it drives the second guide rod 601 to rotate. Since the connection mode between the second support frame 4 and the support plate 501 is a sliding connection, and the third guide grooves 602 are equidistantly distributed inside the second rotating rod 505, and the third guide grooves 602 communicate with each other, and the top-down appearance structure of the third guide groove 602 is in a "V" shape, the second guide rod 601 moves left and right along the track of the third guide groove 602, driving the support plate 501 to move left and right, making the cutter 515 move left and right, and making it easier to separate the aquatic plants and other sundries.
