[0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic plants and animals under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial feeding and management. In a broad sense, it also includes the proliferation of aquatic resources. Salvage refers to the process of getting objects submerged below the water surface out of the water, taking things out of the liquid. In the process of aquaculture, due to a series of competitive relationships, dead fish often appear in fish ponds. In order to prevent dead fish from polluting the environment in the fish pond, people will take a small boat to salvage the dead fish, but the manual salvage process requires rowing while salvaging, which is time-consuming and laborious.

[0003] In the prior art, for example, announcement number CN211006592U proposes a dead fish salvaging device for aquaculture.

A driving box 4 is fixedly connected to one side of the support frame 1. One end of the salvage roller 3 is rotatably connected to a rotating shaft 5, and the rotating shaft 5 extends to the inside of the driving box 4. One end of the rotating shaft 5 extending to the inside of the driving box 4 is fixedly connected to a driving wheel 6. The inside of the driving box 4 is located below the driving wheel 6 and is rotatably connected to a driven wheel 7. A belt 8 is sleeved on the driving wheel 6 and the driven wheel 7. A connecting rod 9 is fixedly connected to one side of the driven wheel 7. The connecting rod 9 penetrates the driving box 4 and is rotatably connected to the driving box 4. A connecting rod 9 is rotatably connected to the inner wall of the support frame 1 away from the driving box 4. A rotating rod 10 is connected between the two connecting rods 9. The outer wall of the rotating rod 10 is sleeved with a plurality of circular rings 11, and the outer walls of the circular rings 11 are fixedly connected with blades 12.

[0025] Specific working principle and implementation method: According to the prior art of patent number CN211006592U, when the staff uses the device to salvage dead fish, due to the presence of a large amount of aquatic plants in the water body, the device can clean up the dead fish and smaller aquatic plants in the water body during operation, but there will still be a large amount of aquatic plants entangled on the salvage roller 3. If the aquatic plants on the salvage roller 3 are not cleaned in time, when too much aquatic plants are entangled on the salvage roller 3, it will affect the normal operation of the device and even cause damage to the device; therefore, there are technical problems mentioned in the background technology; The above-mentioned scheme is designed to solve the above-mentioned problems. During the operation of the device, the dead fish and some aquatic plants can be transported to the conveyor belt 2 by rotating the salvage roller 3, and then transported to the storage box along the conveyor belt 2. The rotation of the salvage roller 3 can drive the driving wheel 6 to rotate. The driving wheel 6 can also drive the driven wheel 7 through the belt 8. The rotation of the driven wheel 7 can drive the rotating rod 10 to rotate. The rotation of the rotating rod 10 can rotate the blade 12 on the ring 11, thereby cutting off the aquatic plants wrapped around the salvage roller 3, thereby ensuring the normal operation of the device and making the cleaning effect of the aquatic plants inside the water body of the device better.

[0026] like Figure 3 and Figure 6As shown, both ends of the rotating rod 10 are fixedly connected with an insertion rod 13, and one end of the connecting rod 9 is provided with a slot 14 matching the insertion rod 13, and the inner wall of the slot 14 on one of the connecting rods 9 is slidably connected with a movable plate 15, and one side of the movable plate 15 is fixedly connected with a telescopic rod 16, and the other end of the telescopic rod 16 is fixedly connected to the inner wall of the slot 14, and the outer wall of the telescopic rod 16 is sleeved with a spring 17, one end of the spring 17 is fixedly connected to the movable plate 15, and the other end is fixedly connected to the inner wall of the slot 14, and the outer wall of the connecting rod 9 is penetrated by a first screw 18, and the first screw 18 is threadedly connected to the insertion rod 13. When the device is used for a long time, the staff needs to disassemble the rotating rod 10 to clean or replace the blade 12. The staff can easily disassemble the rotating rod 10 by removing all the first screws 18. When people install the rotating rod 10, first insert one end of the rotating rod 10 into the interior of one of the connecting rods 9, squeeze the rotating rod 10 inward to make the movable plate 15 move into the slot 14, and after moving to a certain extent, the other end of the rotating rod 10 can be inserted into the interior of the other connecting rod 9, and then all the first screws 18 are installed, and the device can operate normally. The advantage of such a setting is that it can make it easier for people to disassemble and assemble the rotating rod 10, thereby making it easier for people to repair the device.

[0027] like Figure 4 As shown, the ring 11 is penetrated by a second screw 21, and the second screw 21 is threadedly connected to the rotating rod 10. After the device is used for a long time, the blade 12 on the ring 11 may rust or be damaged, so the staff needs to replace the blade 12 regularly. The ring 11 and the rotating rod 10 are fixedly connected by the second screw 21, which makes it convenient for people to disassemble the ring 11 and makes the device more stable during operation, so that the device can maintain a better cutting effect on the water plants wrapped around the salvage roller 3.

[0028] like Figure 3 and Figure 5 As shown, the inner wall of the circular ring 11 is fixedly connected with a symmetrical guide block 19, and the outer wall of the rotating rod 10 is provided with a long groove 20 matching the guide block 19. When people install the circular ring 11, they need to align the guide block 19 with the long groove 20, so as to better limit and guide the circular ring 11, thereby making it more convenient for people to install the circular ring 11.

[0029] like Figure 4 and Figure 6As shown, the outer wall of the insertion rod 13 is fixedly connected with a pair of symmetrical sliders 22, and the inner wall of the slot 14 is provided with a slide groove 23 matching the slider 22. When people install the rotating rod 10, they need to align the slider 22 on the insertion rod 13 with the slide groove 23 on the inner wall of the slot 14, which can play a better guiding role for the rotating rod 10, thereby making it more convenient for people to install the first screw 18, and further making it more convenient for people to install the rotating rod 10.

[0030] like Figure 5 As shown, there are multiple blades 12 on each ring 11, and the blades 12 are evenly distributed on the ring 11 in a circular array. By setting the number of blades 12 on each ring 11 to be multiple, the cutting efficiency of the device for the aquatic plants wrapped around the salvage roller 3 can be effectively improved, so that the device can better clean the aquatic plants inside the water body when in use.

[0031] like Figure 4 As shown, an anti-skid sleeve 24 is sleeved on the outer wall of one end of the rotating rod 10, and the outer wall of the anti-skid sleeve 24 is provided with anti-skid grooves. When people disassemble and assemble the rotating rod 10, they need to hold the rotating rod 10. The anti-skid sleeve 24 provided on one end of the rotating rod 10 and the anti-skid grooves provided on the outer wall of the anti-skid sleeve 24 can effectively increase the friction between people's hands and the outer wall of the rotating rod 10, prevent people's hands from slipping, and make it more convenient for people to take the rotating rod 10.

[0032] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
