With reference to the above embodiment, the working process of the present invention is as follows:
in operation, when the conveying trolley 110 is moved to a proper position, the second cylinder and the fourth cylinder are activated, the second cylinder drives the first housing 130 to slide downwards, and the fourth cylinder drives the second housing 140 to slide downwards synchronously. When the lower extreme butt joint of first casing 130 connects to mud under water, start first motor and third motor simultaneously, first motor drives first casing 130 and rotates, the third motor drives second casing 140 and rotates in step, when first casing 130 rotates, broken sword 270 is not hard up mud under water, along with first casing 130 and second casing 140 synchronous downstream and rotation, make the mud after broken sword 270 is not hard up pass through feed inlet 260 inside entering storage cavity 141, along with the promotion of second cylinder to first casing 130, storage cavity 141 is full of mud gradually. At this time, the first motor, the second cylinder and the fourth cylinder are stopped, the third motor continues to rotate, so that the second shell 140 and the first shell 130 rotate relatively, and due to the first toothed ring 290 meshed with the second toothed ring 143 at the lower end of the second shell 140, the second shell 140 rotates to drive the first block 281 to rotate on the first plate 211, so that the first block 281 seals the feed opening 260 on the first plate 211; meanwhile, the second housing 140 rotates to drive the second block 282 to rotate on the second plate 212, so that the second block 282 blocks the feed port 260 on the second plate 212, and the flow of sludge from the feed port 260 to the storage cavity 141 is reduced.
After the feed port 260 is sealed, the third motor is stopped, the second cylinder and the fourth cylinder are started at the same time, the first shell 130 and the second shell 140 move upwards synchronously under the driving of the second cylinder and the fourth cylinder, the lower end of the first shell 130 is gradually separated from the water surface, the first shell 130 and the second shell 140 move synchronously to the position above the stacked sludge by controlling the driving trolley, at the moment, the second cylinder is stopped, the second shell 140 and the first shell 130 move relatively under the continuous driving of the fourth cylinder, the second ring 143 at the lower end of the second shell 140 is separated from the first ring gear 290 when the second shell 140 moves upwards in the mounting cavity 131, the fourth ring gear 144 on the side wall of the second shell 140 is meshed with the third ring gear 311 on the driving ring 310, and the lower end of the second shell 140 is separated from the inner side walls of the first fixing block 220 and the second fixing block 240, and the first plate 211 and the second plate 212 are both rotated downwards by a certain angle under the action of the self gravity of the sludge, so that a certain gap between the first plate 211 and the second plate 212 is opened. When the second housing 140 slides upwards, the limiting block 410 gradually enters the limiting ring groove 145, at this time, the fourth cylinder is stopped, and the second housing 140 cannot slide downwards under the action of its own gravity under the action of the limiting block 410. The third motor is started at this moment, the third motor drives the second housing 140 to rotate, the fourth toothed ring 144 fixedly arranged on the outer side wall of the second housing 140 drives the driving ring 310 to rotate, the plurality of pushing blocks 312 arranged on the peripheral side wall of the lower end of the driving ring 310 push the outer side wall of the first fixing block 220 and the outer side wall of the second fixing block 240, so that the first plate 211 and the second plate 212 are quickly away from each other, the gap between the first plate 211 and the second plate 212 is further increased until the opening of the installation cavity 131 is completely opened, and sludge is quickly separated from the storage cavity 141 under the action of self gravity.
After the opening of the installation cavity 131 is completely opened, the fifth cylinder is started, the fifth cylinder pushes the cleaning disc 510 to slide downwards, the side wall of the cleaning disc 510 is connected with the side wall of the storage cavity 141 in a sliding and sealing manner, the cleaning disc 510 slides downwards in the storage cavity 141, the cleaning disc 510 cleans the inner side wall of the second shell 140, when the lower end of the sliding part 522 of the scraper 520 abuts against the fixed stop ring 550 at the lower end of the second shell 140, along with the further pushing of the fifth cylinder, the sliding part 522 slides upwards along the sliding groove, and the sliding part 522 extrudes the second spring 523. Because the first driving block 530 fixedly connected to the middle of the sliding part 522 is disposed in the driving groove 511, and the guide block disposed on the side wall of the first driving block 530 slides along the spiral groove on the side wall of the driving groove 511, when the sliding part 522 slides upwards along the sliding groove, the first driving block 530 synchronously slides along the driving groove 511, and compresses the third spring 540, the first driving block 530 rotates under the action of the guide block and the spiral groove, the fixing part 521 rotates on the lower end surface of the cleaning plate 510 under the driving of the first driving block 530, and the fixing part 521 cleans the lower end surface of the cleaning plate 510, so as to reduce the attachment of sludge on the lower end surface of the cleaning plate 510.
After the cleaning of the bottom surface of the cleaning tray 510 is completed, the fifth cylinder is activated, pulls the cleaning tray 510 to slide upward, restores the cleaning tray 510 to the original height, and simultaneously restores the fixing portion 521 and the sliding portion 522 to the original position under the combined action of the second spring 523 and the third spring 540. Then, the third motor is started to rotate for a fixed angle, the third motor rotates to drive the second housing 140 to rotate for a fixed angle, the second housing 140 drives the driving ring 310 to rotate for a fixed angle, a certain gap is formed between two adjacent pushing blocks 312 arranged at the lower end of the driving ring 310, so that the pushing blocks 312 do not push the outer side walls of the first fixing block 220 and the second fixing block 240 any more, and under the action of the first torsion spring and the second torsion spring, the first plate 211 and the second plate 212 deflect, so that the first plate 211 and the second plate 212 close the opening of the installation cavity 131 again. Then, the fourth cylinder is started, the fourth cylinder pushes the second housing 140 to slide downwards, so that the side wall of the lower end of the second housing 140 abuts against the inner side wall of the first fixing block 220 and the inner side wall of the second fixing block 240 again, the second toothed ring 143 at the lower end of the second housing 140 is engaged with the first toothed ring 290 on the first block 281 and the first toothed ring 290 on the second block 282, then the fourth cylinder is stopped, the third motor is started to rotate for a fixed angle, the third motor rotates to drive the second housing 140 to rotate for a fixed angle, the second housing 140 rotates to drive the first block 281 and the second block 282 to rotate for a fixed angle, and the feed port 260 on the first plate 211 and the feed port 260 on the second plate 212 are opened again. Therefore, underwater sludge is repeatedly and rotatably dug.
