[0032] Embodiment 1

[0033] like Figure 3-4As shown, in the present embodiment, the collecting mechanism 200 comprises a collecting box 210, and a collecting port 218 is provided on the side wall of the collecting box 210 which is in contact with the conveying box 120, and two opposite outer walls of the collecting box 210 are provided with two strip grooves 211, and a water filter plate 223 is provided on the inner wall of the collecting box 210, and two opposite side walls of the water filter plate 223 are fixedly connected with moving blocks 222, and the outer walls of the two moving blocks 222 are respectively slidably connected with the two strip grooves 211, and the two outer walls of the collecting box 210 with the strip grooves 211 are symmetrically fixedly connected with a fixed block 1 212 and a fixed block 2 213, and a screw rod 221 is rotatably connected between the fixed block 1 212 and the fixed block 2 213, and the outer walls of the two screw rods 221 are respectively screwed together with the inner walls of the two moving blocks 222, and the top surfaces of the two fixed blocks 1 212 are fixedly connected with a motor 3 220, and the motor shafts of the two motors 3 220 are respectively connected with the inner walls of the two moving blocks 222, and the top surfaces of the two fixed blocks 1 212 are fixedly connected with a motor 3 220, and the motor shafts of the two motors 3 220 are respectively connected with the inner walls of the two moving blocks 222. One end of the two screw rods 221 is transmission connected, and the collecting box 210 is connected to the box door 214 by a hinge at the upper position of the side wall away from the conveying box 120. Two rotating seats 215 are symmetrically fixed to the outer wall of the box door 214. Two support rods 216 are symmetrically fixed to the outer wall of the collecting box 210. The top surfaces of the two support rods 216 are fixedly connected to the rotating seat 219. The insides of the two rotating seats 219 are rotatably connected to the electric telescopic rods 217.

[0034] In this embodiment, the floating objects and other solid wastes conveyed by the conveyor belt 122 enter the collection box 210 through the collection port 218 and fall on the intercepted water filter plate 223. The pool water entering the collection box 210 along with the floating objects and other solid wastes will pass through the water filter plate 223 and accumulate at the bottom of the collection box 210. The water pump 130 can be started to extract the liquid inside the collection box 210 through the water pump pipe 131 and discharge it into the pond from the drain pipe 132, so that the garbage in the collection box 210 remains roughly dry. When there is enough garbage stored in the collection box 210, the two drain pipes 132 are driven at the same time.

[0036] During specific implementation, the hydraulic rod 421 is controlled to extend so that the fixing plate 422 drives the bellows 423 to stretch and move downward, so that the auger 428 contacts the silt at the bottom of the pond, and the motor shaft of the driving motor 431 is transmitted to the sleeve 430, so that the gear 2 433 and the gear ring 2 425 are meshed and transmitted, so that the stirring blade 427 and the auger 428 are connected with the connecting rod 426 and rotate synchronously with the sleeve 424, and the auger 428 penetrates into the silt layer to loosen the silt that is too thick and hardened, and the stirring blade 427 stirs the pool water to suspend the broken silt to form a mud-water mixture, and the dredging pump 410 is started to make the sliding rod 432 extract the mud-water mixture to achieve the dredging effect. By arranging two dredging mechanisms 400 on the device, the scope of dredging is expanded and the work efficiency is improved.

[0037] Embodiment 2

[0038] On the basis of the first embodiment, in order to make up for the defect that the sludge extracted by the silt clearing mechanism 400 in the first embodiment has a high water content, resulting in the equipment being overloaded.

[0039] like Figure 5-6As shown, in the present embodiment, the mud-water separation mechanism 300 includes an outer cover shell 310, and the bottom surface of the outer cover shell 310 is symmetrically fixedly connected with four support legs 316, and the bottom ends of the four support legs 316 are fixedly connected to the top surface of the conveying box 120, and the end side of the outer cover shell 310 is rotatably connected with a feed pipe 314, and the feed pipe 314 extends to the outer wall of the inner part of the outer cover shell 310 and is sleeved and fixed with a one-way bearing 330, and the outer wall of the one-way bearing 330 is sleeved and fixed with a cylindrical filter screen 331, and the other end of the cylindrical filter screen 331 is rotatably connected to the side wall of the outer cover shell 310, and a spiral conveying blade 320 is arranged inside the cylindrical filter screen 331, and the spiral conveying blade 320 is fixedly connected to the outer wall of the feed pipe 314, and the end side of the outer cover shell 310 is fixedly connected with a motor frame 311, and the motor frame 311 A motor 4 312 is fixedly connected to the upper portion, and a motor shaft of the motor 412 is transmission-connected with a gear 1 313. A gear ring 1 315 is sleeved and fixedly connected to the outer wall of the feed pipe 314, and the gear ring 1 315 and the gear 1 313 are meshed for transmission.
