When people need clean the dirt of the breed case that aquaculture used, can use this kind of dirt cleaning device for aquaculture, at first people need manually promote the operation of lifting unit 6, make can put the breed case on lifting unit 6, stop afterwards promote can, then start cleaning unit 5, the operation of cleaning unit 5 drives first brush 3 and the operation of second brush 4, make can carry out cleaning treatment to the dirt in the breed case, close cleaning unit 5 after having cleaned the breed case, promote lifting unit 6 operation afterwards again, make can take out the breed case that is clean, it can to take out the back loose hand.

After breeding the case and putting on lifting unit 6, people can start gear motor 54, gear motor 54 starts the back, gear motor 54's output shaft rotates and drives pivot 55 and rotate, thereby drive first brush 3 and second brush 4 and all rotate, make and to carry out cleaning to the dirt in breeding the case, realize clear effect, people can promote second slide rail 52 seesaw, thereby drive first slider 53, gear motor 54, pivot 55, first brush 3 and the equal seesaw of second brush 4, promote first slider 53 side-to-side movement again afterwards, thereby drive gear motor 54, pivot 55, the equal side-to-side movement of first brush 3 and second brush 4, make can the omnidirectional carry out cleaning to breeding the case, after clean close gear motor 54 can.

People need promote workstation 63 downstream, thereby drive telescopic link 61 by the shrink, first compression spring 62 is compressed, subsequently people can put breed the case at workstation 63 and pine hand, because first compression spring 62 resets and drives telescopic link 61 and reset, thereby drive workstation 63 upward movement, make breed the case and can be located second brush 4 below, after clean, people need promote workstation 63 downstream once more, make and take out the breed case that has cleaned, it can to take out the back pine hand, because first compression spring 62 resets and drives telescopic link 61 and reset, thereby drive workstation 63 upward movement.

When the rotating shaft 55 rotates, the rotating shaft 55 drives the spline 73, the gear 74 and the limiting block 77 to rotate, when the gear 74 rotates, the rack 72 drives the gear 74 to move rightwards, so as to drive the spline 73, the limiting block 77, the rotating shaft 55 and the first slider 53 to move rightwards, so as to compress the first spring rod assembly 71, when the first slider 53 moves rightwards and contacts with the first wedge 76 on the right side, the first wedge 76 on the right side moves downwards, so as to drive the second spring rod assembly 75 to be compressed, the first wedge 76 on the right side moves downwards and to move the gear 74, so as not to be meshed with the rack 72, because the first spring rod assembly 71 resets and drives the first slider 53 to move leftwards, so as to drive the spline 73, the limiting block 77, the rotating shaft 55 and the gear 74 to move leftwards, when the limiting block 77 moves leftwards and contacts with the first wedge 76 on the left side, so as to move the first wedge 76 on the left side upwards, thereby causing the left second spring rod assembly 75 to be compressed, the left first wedge block 76 moves upwards to cause the gear 74 to move upwards and reset, and is meshed with the rack 72 and can move leftwards again, so that the limit block 77 is not contacted with the left first wedge block 76, and the left second spring rod assembly 75 resets to cause the left first wedge block 76 to move downwards and reset.

People's accessible is outside with water injection pipe 81, when workstation 63 upward movement and limiting plate 84 contact, make limiting plate 84 upward movement, thereby make third spring rod subassembly 83 compressed, and then drive connecting rod 85 and the equal upward movement of stopper 86, make stopper 86 can not block up water pipe 81, hydroenergy is flowed out through water pipe 81, flow into the breed case, realize the effect of washing, and when workstation 63 downward movement and limiting plate 84 contactless, because third spring rod subassembly 83 resets and drives limiting plate 84 downstream, thereby drive connecting rod 85 and the equal downstream of stopper 86, make stopper 86 can block up water pipe 81, and make water can not flow out.

People need stimulate the clamp plate 93 and move dorsad, second compression spring 92 is compressed, people can put breed the case on workstation 63 this moment, put well the back loose hand can, because second compression spring 92 resets and drives clamp plate 93 and move in opposite directions, make clamp plate 93 can press from both sides the breed case tightly, prevent to breed the case when clear and take place the displacement, realize the tight effect of clamp, when needs will breed the case and take out, people can stimulate clamp plate 93 dorsad once more, people can take out the breed case this moment, take out the back loose hand, because second compression spring 92 resets and drives clamp plate 93 and move in opposite directions and reset.

When the workbench 63 moves downwards, the workbench 63 drives the first guide rod 91, the second compression spring 92 and the clamping plate 93 to move downwards, so as to drive the slide way 102, the second guide rod 103 and the second slide block 104 to move downwards, when the second slide block 104 moves downwards to contact with the second wedge block 101 on the same side, the second wedge block 101 enables the second slide block 104 to move backwards, so as to drive the clamping plate 93 on the same side to move backwards, so that the automatic release can be realized, the manual pushing is not needed, the releasing effect is realized, when the workbench 63 moves upwards to drive the first guide rod 91, the second compression spring 92 and the clamping plate 93 to move upwards, so as to drive the slide way 102, the second guide rod 103 and the second slide block 104 to move upwards, when the second slide block 104 moves upwards to not contact with the second wedge block 101 on the same side, the clamping plate 93 is driven to move towards each other to reset due to the reset of the second compression spring 92, thereby driving the second sliding block 104 to move towards each other and reset.

When the reduction motor 54 moves forward, the reduction motor 54 drives the third support frame 111, the bolt 112 and the waterproof cover 113 to move forward, at this time, water is sprayed out from the water pipe 81, water can flow onto the waterproof cover 113, the waterproof cover 113 can prevent the water from flowing onto the reduction motor 54, a waterproof effect is achieved, and when the reduction motor 54 moves backward, the reduction motor 54 drives the third support frame 111, the bolt 112 and the waterproof cover 113 to move backward and reset.
