[0019] In the embodiments provided in the application, the carrying mechanism 1 can further include a universal wheel connected to the bottom of the object plate 13 and a pushing rod fixedly connected to the bearing plate 11, and the pushing plate is provided with a handle 6 at the end away from the bearing plate 11. The staff can hold the handle 6 and push the entire aquaculture pond sludge cleaning device to move in the aquaculture pond. The top of the first support 12 is fixedly connected to the bearing plate 11, so that the first support 12 can support the bearing plate 11. The mounting plate 111 can be perpendicular to the bearing plate 11, and the through hole 111a on the mounting plate 111 can be a square through hole 111a extending along the length direction of the mounting plate 111. The suction member 2 can include a suction head arranged in a fan shape, a suction plate, and a rotating plate, the inside of the suction head and the suction plate are both provided with a cavity in communication with each other, and the suction pipe 31 is connected in communication with the suction plate. The rotating plate is fixedly connected to the suction plate at one end and rotatably connected to the bearing plate 11 at the other end. The suction plate is partially located in the through hole 111a, and the suction plate can be bent downward, so that the suction head contacts the bottom of the aquaculture pond downward, facilitating the suction of the sludge. The suction pump 3 is further connected with a sewage pipe 32, and the sludge will enter the sewage pipe 32 from the suction pipe 31 and be discharged from the aquaculture pond by the sewage pipe 32. The mud scraping plate 41 and the first stretching member 5311 can be perpendicular to each other, the first stretching member 5311 can move back and forth along a horizontal straight line in the length direction thereof, and the end of the mud scraping plate 41 away from the first stretching member 5311 can contact the bottom of the aquaculture pond. When the first stretching member 5311 moves, the mud scraping plate 41 can scrape the sludge at the bottom of the aquaculture pond to the side close to the carrying mechanism 1.

[0020] Before the sludge at the bottom of the aquaculture pond is sucked, the agglomerated sludge can be dispersed with water, so that the suction member 2 can suck the sludge. Then the staff pushes the carrying mechanism 1 to move in the large aquaculture pond, and the driving mechanism 5 and the suction pump 3 operate, the driving mechanism 5 makes the suction member 2 swing back and forth along the extension direction of the through hole 111a, increases the range of the suction member 2 to suck the sludge, and improves the cleaning efficiency of the sludge at the bottom of the large aquaculture pond. The operation of the driving mechanism 5 makes the first stretching member 5311 move back and forth in the length direction thereof, and then the mud scraping plate 41 can continuously approach the carrying mechanism 1, scrape the sludge far away, gather the sludge dispersed far away near the carrying mechanism 1, facilitate the suction of the sludge by the suction member 2, suck more sludge, and further improve the cleaning efficiency of the sludge.

[0021] In some embodiments of the present application, the driving mechanism 5 comprises a double-shaft motor 51, a strip-shaped hole 21, a first disc 52 and a second disc 53. The double-shaft motor 51 is fixedly arranged through the bearing plate 11. The strip-shaped hole 21 is arranged on the suction member 2. The lower surface of the first disc 52 is fixedly connected with one of the output shafts of the double-shaft motor 51. The upper surface of the first disc 52 is fixedly connected with a driving column 521 away from the center of the first disc 52. The driving column 521 is movably arranged through the strip-shaped hole 21. The upper surface of the second disc 53 is fixedly connected with the other output shaft of the double-shaft motor 51. The lower surface of the second disc 53 is hingedly connected with a connecting plate 531 away from the center of the second disc 53. One end of the connecting plate 531 away from the second disc 53 is hingedly connected with the other end of a first stretching member 5311.

[0022] The double-shaft motor 51 has two output shafts. The main body of the double-shaft motor 51 can be embedded in the bearing plate 11. Both of the output shafts of the double-shaft motor 51 extend out of the bearing plate 11. The strip-shaped hole 21 extends along the length direction of the suction member 2. The driving column 521 can be located at the edge of the first disc 52.

[0023] When the double-shaft motor 51 is started, the first disc 52 rotates. The driving column 521 on the first disc 52 moves in the strip-shaped hole 21 and drives the suction member 2 to reciprocate in the through hole 111a. At the same time, the second disc 53 also rotates under the driving of the double-shaft motor 51. The second disc 53, the connecting plate 531, the first stretching member 5311 and the first fixed block 55 form a crank slider mechanism. When the second disc 53 rotates, the connecting plate 531 moves, and the first stretching member 5311 reciprocates.

[0024] If the suction member 2 does not timely suck the bottom mud, when the mud scraping plate 41 moves away from the carrying mechanism 1, the mud scraping plate 41 scrapes the remaining sludge away from the carrying mechanism 1. In order to reduce the amount of sludge scraped away when the mud scraping plate 41 moves away from the carrying mechanism 1, in some embodiments of the present application, the side of the bearing plate 11 away from the mounting plate 111 is fixedly connected with a first mounting seat. The first mounting seat movably penetrates a first follower plate 42. The first follower plate 42 is provided with a first stop block 421. The mud scraping plate 41 is rotatably connected with the end of the first follower plate 42 away from the first mounting seat. The mud scraping plate 41 is provided with a first square hole 411. One end of the first stretching member 5311 is fixedly connected with a first mounting column. The first mounting column movably penetrates the first square hole 411.

[0025] When one end of the first stretching member 5311 moves towards the direction close to the carrying mechanism 1, the first mounting column will move in the first square hole 411, so that the mud scraping plate 41 rotates towards the first stop block 421. When the bottom of the mud scraping plate 41 contacts the bottom of the culture pond, the mud scraping plate 41 will abut against the first stop block 421. With the continuous rotation of the mud scraping plate 41, the first stop block 421, the first follower plate 42 and the mud scraping plate 41 will move close to the carrying mechanism 1 under the pulling of the first stretching member 5311, thereby scraping the far away bottom mud close. When one end of the first stretching member 5311 moves away from the carrying mechanism 1, the mud scraping plate 41 will rotate and move away from the bottom of the culture pond under the pushing of the first stretching member 5311, that is, the mud scraping plate 41 will not contact the bottom mud during the process of moving away from the carrying mechanism 1. In this way, the first stretching member 5311 will continuously scrape the mud from far away close to the mud scraping plate 41 during the reciprocating movement, thereby improving the suction efficiency of the suction member 2.

[0026] In some embodiments of the present application, the carrying mechanism 1 further comprises a second support member fixedly connected with the part of the bearing plate 11 away from the first support member 12. The mud scraping mechanism 4 further comprises a second mounting seat, a mud scraping plate, a second fixed block, a second stretching member and a transmission structure. The second mounting seat movably penetrates the second follower plate, and the second follower plate is provided with a second stop block. The mud scraping plate is rotatably connected with the end of the second follower plate away from the second mounting seat and corresponds to the second stop block. The mud scraping plate is provided with a second square hole. The second fixed block is fixedly connected with the second support member. The second stretching member movably penetrates the inside of the second fixed block along the length direction thereof. One end of the second stretching member is provided with a second mounting column, and the second mounting column movably penetrates the second square hole. The transmission structure is connected with the other end of the double-shaft motor 51 and the other end of the second stretching member, so that the second stretching member can reciprocate along the length direction thereof. The mud scraping plate and the mud scraping plate 41 can scrape the mud on both sides of the carrying mechanism 1 close. The setting of the mud scraping plate can improve the range of mud scraping and further improve the cleaning effect of the culture pond bottom mud.

[0027] In order to enable the mud scraping plate 41 and the dirt scraping plate to simultaneously scrape the far away sludge close after the second disc 53 rotates, please refer to 3, the transmission structure can include a third disc 112, a rotating shaft, a driving pulley, a driven pulley, a synchronous belt and a connecting body, the third disc 112 is rotationally connected to the bottom of the bearing plate 11, the driving pulley is connected to the other end of the dual-shaft motor 51, the driven pulley is connected to the rotating shaft, the synchronous belt is connected to the driving pulley and the driven pulley, one end of the connecting body is hingedly connected to the edge of the third disc 112, and the other end of the connecting body is hingedly connected to the other end of the second stretching piece; in this way, when the dual-shaft motor 51 is started, the second disc 53 rotates, the third disc 112 rotates through the synchronous belt, the third disc 112, the connecting body, the second stretching piece and the second fixed block also form a crank slider mechanism, the third disc 112 rotates, the connecting body moves, and then the second stretching piece reciprocatingly moves, so that the mud scraping plate 41 and the dirt scraping plate simultaneously scrape the far away sludge close after the dual-shaft motor 51 is started.

[0028] Of course, in some embodiments of the present application, please refer to Figure 1 , the transmission structure includes a first rack 54, a second rack 5411 and a fixed plate, the first rack 54 is fixedly connected to the other end of the first stretching piece 5311; the second rack 5411 is fixedly connected to the other end of the second stretching piece; one end of the fixed plate is fixedly connected to the bearing plate 11, and the other end is rotationally connected with a gear wheel 541 which engages the first rack 54 and the second rack 5411.

[0029] When one end of the first stretching piece 5311 moves away from the carrying mechanism 1, the first rack 54 moves, and through the engagement with the gear wheel 541, the second rack 5411 also moves, and then the other end of the second stretching piece also moves away from the carrying mechanism 1. In this way, the mud scraping plate 41 and the dirt scraping plate simultaneously scrape the far away sludge close, which can greatly improve the suction efficiency of the suction piece 2.

[0030] In some embodiments of the present application, please refer to Figure 4 , the mounting plate 111 is provided with a telescopic air cylinder 7, the telescopic end of the telescopic air cylinder 7 is connected with a pulling rod 71, the pulling rod 71 is fixedly connected with a vertical plate 711, the high-pressure nozzle 8 is installed on the surface close to the carrying mechanism 1 of the vertical plate 711, the high-pressure nozzle 8 is arranged at an angle with the vertical plate 711, the water pump 131 is arranged on the object carrying plate 13, and the water pump 131 is connected with the high-pressure nozzle 8.

[0031] The water pump 131 can be connected with the water delivery pipe and the high-pressure spray head 8, and multiple high-pressure spray heads 8 can be arranged. When the telescopic air cylinder 7 is started, the pulling rod 71 can reciprocate to make the high-pressure spray head 8 move from far to near and from near to far. The high-pressure water flow sprayed by the high-pressure spray head 8 can spray the sludge clumps in front of the suction member 2 back and forth, so that the sludge is scattered and mixed with water, and the suction of the suction member 2 to the sludge is facilitated. The high-pressure spray head 8 is arranged at an angle with the vertical plate 711, so that the high-pressure spray head 8 can spray the high-pressure water flow to the position close to the carrier mechanism 1, preventing the high-pressure water flow sprayed by the high-pressure spray head 8 from blowing the sludge in front away. The arrangement of the high-pressure spray head 8 can spray the high-pressure water flow to the bottom of the breeding pond at the same time as the suction, without the need to spray water to the bottom of the breeding pond in advance.

[0032] Further, the surface of the vertical plate 711 away from the high-pressure spray head 8 is fixedly connected with a fixed seat, and the fixed seat is rotationally connected with a scraping plate. One end of the scraping plate away from the surface of the vertical plate 711 is arranged in an arc shape, and the other end of the scraping plate can abut against the vertical plate 711.

[0033] When the vertical plate 711 moves towards the carrier mechanism 1, the other end of the scraping plate will contact the vertical plate 711, and one end of the scraping plate will scrape the sludge impacted by the high-pressure water flow close to the carrier mechanism 1, improving the suction efficiency. When the vertical plate 711 moves away from the carrier mechanism 1, the arc surface of the scraping plate will touch the sludge not sucked, the scraping plate rotates around its rotation center, the other end of the scraping plate will be separated from the vertical plate 711, and one end of the scraping plate will be lifted correspondingly, which can reduce the amount of sludge pushed away. The arc surface of the scraping plate can further reduce the amount of sludge pushed away.

When the first stretching member 5311 reciprocates, the first rack 54 moves, the first rack 54 is in meshing transmission with the gear 541, the gear 541 is in meshing transmission with the second rack 5411, so that the second rack 5411 reciprocates, drives the second stretching member to reversely move synchronously with the first stretching member 5311, and then the mud scraping plate 41 and the mud scraping plate can simultaneously scrape the mud far away to the nearby. After the telescopic cylinder 7 is started, the pulling rod 71 reciprocates, and then the vertical plate 711 moves, so that the mud scraping plate scrapes the mud far away to the nearby, the water pump 131 is started, the high-pressure nozzle 8 sprays the high-pressure water flow to the mud in front of the sewage suction member 2, and the sewage pump 3 is started, so that the mud sucked by the sewage suction member 2 is discharged through the sewage suction pipe 31 and the sewage discharge pipe 32.
