DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-6 , a dead fish salvaging equipment for aquaculture, comprising a screen assembly for salvaging dead fish, a traction mechanism for driving the screen assembly to rotate, and a conveying mechanism for conveying dead fish, the traction mechanism and the conveying mechanism float on the water surface through a suspension seat 7, a universal wheel 10 with a self-locking structure is arranged at the bottom end of the suspension seat 7 (the arrangement of the universal wheel 10 facilitates the movement of the device), the conveying mechanism comprises a conveying cylinder 1 fixedly connected to the top of the suspension seat 7 and a conveying motor 12 installed on the side wall of the conveying cylinder 1, the output end of the conveying motor 12 extends to the inside of the conveying cylinder 1 and is fixedly connected to a conveying shaft, and the surface of the conveying shaft is provided with a spiral conveying blade 11 for conveying dead fish;

[0027] It should be noted that the conveying motor 12 drives the spiral conveying blade 11 to rotate, so as to realize the conveying function of the dead fish, so that the dead fish are discharged through the opening on one side of the conveying cylinder 1 and then fall into the inner side of the collecting tank 71 for collection.

[0028] The surface of the conveying cylinder 1 is rotatably connected with a guide plate 6 arranged oppositely, and the guide plate 6 is in an "eight" shape, which can collect the dead fish flowing to the downwind outlet. The screen assembly is arranged between the guide plates 6 and connected to the guide plates 6. The screen assembly includes hollow plates 5 arranged oppositely and hollow adapter blocks 51 evenly distributed between the hollow plates 5. Expandable elastic tubes 52 are fixedly connected between the hollow adapter blocks 51, and the hollow adapter blocks 51 are fixedly connected to the side walls of the hollow plates 5 through the elastic tubes 52.

[0029] The top of the suspension seat 7 is fixedly connected to a water-blocking box 4, one side of which is fixedly connected to the conveying tube 1, an air pump 9 is installed on the inner wall of the water-blocking box 4, and the air pump 9 is fixedly connected to the hollow plate 5 through an air delivery hose.

[0030] It should be noted that when dead fish need to be salvaged, the elastic tubes 52 are kept in a deflated state. At this time, the spacing between the elastic tubes 52 is large. When the screen assembly salvages the dead fish, the algae will pass through the spacing between the elastic tubes 52 and will not be salvaged. Only the dead fish will be salvaged.

[0031] When it is necessary to salvage algae, the screen assembly is reset, and then the air pump 9 is used to pump air into the inner side of the screen assembly to expand the elastic tubes 52, thereby reducing the gaps between the elastic tubes 52, thereby achieving the function of salvaging algae in the water.

[0032] The traction mechanism includes a double-axis motor 2 installed on the top of the suspension seat 7, and the output ends of both sides of the double-axis motor 2 are fixedly connected with a winding wheel, and the surface of the winding wheel is wound with a traction rope 22 for pulling the guide plate 6 to rotate. Guide wheels 21 are installed at both ends of the conveying cylinder 1, and the traction rope 22 is fixedly connected to the guide plate 6 through the guidance of the guide wheel 21;

[0033] It should be noted that: the dual-axis motor 2 is used to drive the winding wheel to rotate, the winding wheel rotates and wraps around the traction rope 22, the traction rope 22 drives the guide plate 6 to rotate, and the guide plate 6 drives the screen assembly to rotate, so that the screen assembly is tilted to achieve the dead fish salvage function. The dead fish on the screen assembly will automatically slide to the inside of the conveying cylinder 1.

[0034] An opening is formed at one end of the conveying cylinder 1, and a collecting groove 71 is formed at the top of the suspension seat 7, and a screen plate 8 is fixedly connected between the top of the suspension seat 7 and the collecting groove 71;

[0035] It should be noted that when dead fish fall on the inclined screen plate 8, they will roll to the inside of the collecting tank 71 for collection. When algae fall on the inclined screen plate 8, they will pass through the pores on the screen plate 8 and fall on the suspended seat 7, thereby realizing the screening function of algae and dead fish.

[0036] It is worth noting that: an air release pipe extending underwater is installed on the surface of the hollow plate 5, and an electromagnetic valve is arranged on the air release pipe, and the electromagnetic valve establishes an information transmission connection with the controller.

[0037] A sliding groove is provided on the side wall of the guide plate 6, and a slider 61 is slidably connected in the sliding groove. The slider 61 is fixedly connected to the hollow plate 5. A groove is provided at the bottom end of the slider 61, and a pressure block 64 is slidably connected in the groove. A pressure sensor 63 is installed at the top of the pressure block 64, and a pressure spring 62 is fixedly connected to the bottom end of the pressure block 64 and the inner wall of the sliding groove.

[0038] It should be noted that: a controller is provided inside the suspension seat 7, and the controller establishes information transmission connection with the pressure sensor 63, the conveying motor 12, and the dual-axis motor 2;

[0039] It should be noted that when a large number of dead fish accumulate at the lower air outlet, the screen assembly will be pressed down. When the lower pressure reaches the preset pressure value of the pressure sensor 63, the pressure sensor 63 feeds back to the controller, and the controller controls the dual-axis motor 2 to work.

[0040] A fixing belt 3 is fixedly connected to the surface of the suspension seat 7, and a positioning block 31 is fixedly connected to one end of the fixing belt 3. A through hole is opened inside the positioning block 31, and a fixing nail is inserted into the ground through the through hole to realize the limiting function of the suspension seat 7.

[0041] It should be noted that: the positioning block 31 is fixed on the ground by penetrating the hole with the fixing nail, and the limiting function of the floating seat 7 is realized in cooperation with the fixing belt 3, thereby realizing the limiting function of the device in water.

[0042] The conveying motor 12 is of prior art, and its model is JB5274-91. It can realize the function of driving the spiral conveying blade 11 to rotate, and will not be described in detail here.

[0043] The dual-axis motor 2 is a prior art, and its model is SSJ-76ZY02AV. It can realize the function of driving the rotating drum to rotate, and will not be described in detail here.

[0044] When the present invention is in use, when there are many dead fishes accumulated at the lower air outlet, the screen assembly will be pressed down. When the lower pressure reaches the preset pressure value of the pressure sensor 63, the pressure sensor 63 will feedback to the controller, and the controller will control the double-axis motor 2 and the conveying motor 12 to work. The double-axis motor 2 drives the winding wheel to rotate and wind the traction rope 22. Under the action of the traction rope 22, the guide plate 6 is pulled to rotate, thereby driving the screen assembly to be in an inclined state, so that the dead fish can be salvaged, and the dead fish can slide into the inside of the conveying tube 1, so as to realize the function of automatically salvaging the dead fish.

[0045] When the dead fish are transported out of the conveying cylinder 1 and fall on the inclined screen plate 8, they will roll down to the inside of the collecting tank 71 for collection;

[0046] When it is necessary to salvage the algae, the screen assembly is reset, and then the air pump 9 is used to pump air into the inner side of the screen assembly to expand the elastic tubes 52, thereby reducing the gap between the elastic tubes 52, and realizing the salvage function of the algae in the water;

[0047] The salvaged algae slides down the inner side of the conveying cylinder 1 under the action of the inclined screen assembly. When the algae is conveyed to the screen plate 8, the algae passes through the mesh holes on the screen plate 8 and falls onto the base for recovery.

[0048] When the screen assembly is reset again, the controller controls the solenoid valve to open, so that the air inside the elastic tube 52 is discharged into the water through the vent pipe, so that the expanded elastic tube 52 is reset and the oxygen content in the water is increased, so that the screen assembly can perform dead fish salvage operations again.

[0049] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
