[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0021] This utility model embodiment provides a mitten crab storage pond, such as Figure 1-4 As shown, the mitten crab rearing pond includes: a rearing pond body 1 for raising Chinese mitten crabs, the rearing pond body 1 including multiple rearing ponds 101 for raising Chinese mitten crabs; a mounting frame 2 fixedly installed on the rearing pond body 1; a feeding box 3 mounted on the mounting frame 2 for placing food for raising Chinese mitten crabs; and a feeding mechanism mounted on the feeding box 3 for feeding the food placed in the feeding box 3 into the rearing pond body 1.
[0022] In this embodiment, the device is equipped with a controller of model OMRON E5CC-QX2ASM-800. The controller can control the entire device. When raising Chinese mitten crabs, a certain number of Chinese mitten crabs are placed in different breeding ponds 101. When it is necessary to feed the raised Chinese mitten crabs, the controller activates the feeding mechanism to release the food in the feeding box 3 into multiple breeding ponds 101, thereby completing the feeding of the Chinese mitten crabs. There is no need for staff to operate each one individually, which greatly reduces the labor burden of the staff and improves the breeding efficiency. Through the entire device, Chinese mitten crabs can be raised and the raised Chinese mitten crabs can be automatically fed, reducing the labor burden of the staff and improving the breeding efficiency.
[0023] In a further preferred embodiment of the present invention, the feeding mechanism includes: a first servo motor 5 fixedly installed on the outer wall of one side of the feeding box 3; and a feeding auger 6 rotatably installed inside the feeding box 3, wherein the output shaft of the first servo motor 5 is connected to the rotating shaft of the feeding auger 6 via a coupling.
[0024] In this embodiment, when the feeding mechanism is used, when the feeding box 3 moves above the corresponding breeding pond 101, the first servo motor 5 is started by the controller, which drives the feeding auger 6 to rotate, and pushes the feed in the feeding box 3 evenly into each breeding pond 101, thereby automatically feeding the farmed Chinese mitten crabs. After the feeding work of one breeding pond 101 is completed, the first servo motor 5 is turned off by the controller to stop feeding, and the feeding box 3 continues to move above another breeding pond 101 and then continues to feed.
[0025] In a further preferred embodiment of the present invention, a feeding pipe 4 is rotatably mounted on the feeding box 3, and bevel gears 7 are fixedly sleeved on both the feeding pipe 4 and the feeding auger 6, with the two bevel gears 7 meshing with each other.
[0026] In this embodiment, when the feeding auger 6 rotates, it pushes the food into the feeding pipe 4, and the food is then placed into the breeding pond 101 through the feeding pipe 4. At the same time, when the feeding auger 6 rotates, the interaction of the two bevel gears 7 can drive the feeding pipe 4 to rotate, thereby distributing the food in different positions within the breeding pond 101, avoiding food accumulation and preventing the Chinese mitten crabs from fighting over the food.
[0027] In a further preferred embodiment of the present invention, a mixing mechanism is provided on the feeding box 3. The mixing mechanism is used to mix the food in the feeding box 3. The mixing mechanism includes: a mixing frame 9 rotatably installed in the feeding box 3; and a second servo motor 8 fixedly installed on the feeding box 3. The output shaft of the second servo motor 8 is connected to one end of the mixing frame 9 through a coupling.
[0028] In this embodiment, when multiple feeds or additives need to be fed, simply place them in the feeding box 3 and start the second servo motor 8, which will drive the mixing frame 9 to rotate, thereby fully mixing the various feeds and additives evenly and ensuring that the nutrients in the feed are evenly distributed, which is beneficial to the comprehensive nutritional intake and healthy growth of the Chinese mitten crab.
[0029] In a further preferred embodiment of this utility model, a moving mechanism is provided on the mounting frame 2 and the feeding box 3. The moving mechanism is used to drive the feeding box 3 to move on the storage tank 1. The moving mechanism includes: a lead screw 11 rotatably mounted on the mounting frame 2; a third servo motor 10 fixedly mounted on one side of the mounting frame 2, the output shaft of the third servo motor 10 being connected to one end of the lead screw 11 via a coupling; and a connecting frame 12 threaded onto the lead screw 11, the connecting frame 12 being connected to the feeding box 3.
[0030] In this embodiment, when it is necessary to feed the breeding ponds 101 at different locations, the controller starts the third servo motor 10, which drives the lead screw 11 to rotate. A limit rod is fixedly installed on the mounting frame 2. The limit rod is located on one side of the lead screw 11 and is not displayed because it is blocked by the lead screw 11. The limit rod and the connecting frame 12 are slidably connected. The limit rod limits the connecting frame 12, so that the lead screw 11 drives the connecting frame 12 and the feeding box 3 to move on the storage tank body 1, which facilitates feeding in different breeding ponds 101.
[0031] In a further preferred embodiment of the present invention, a horizontal pipe 13 is fixedly installed on the mounting frame 2, and a plurality of oxygenation pipes 14 are connected to the horizontal pipe 13, and the plurality of oxygenation pipes 14 correspond to the plurality of aquaculture ponds 101 respectively.
[0032] In this embodiment, when raising Chinese mitten crabs, the horizontal pipe 13 is connected to the corresponding oxygen supply pipe of the oxygen supply machine. Through the cooperation of the horizontal pipe 13 and the oxygen supply pipe 14, centralized oxygenation of each breeding pond 101 is achieved. In the process of raising Chinese mitten crabs, the dissolved oxygen in the water is crucial to the growth and survival of the crabs. By ensuring that each breeding pond 101 can obtain sufficient oxygen supply through oxygen supply, it is beneficial to maintain a good ecological environment of the breeding water, promote the healthy growth of Chinese mitten crabs, and improve the survival rate and quality of the breeding.
[0033] In a further preferred embodiment of this utility model, the feeding box 3 is provided with a transparent observation port, which is used to view the inside of the feeding box 3.
[0034] In this embodiment, by setting a transparent observation port on the feeding box 3, it is convenient for staff to intuitively view the remaining amount of feed in the feeding box 3, which helps staff to understand the use of feed in a timely manner.
[0035] In summary, compared with related technologies, this device enables the cultivation of Chinese mitten crabs and can automatically feed the cultivated crabs, reducing the workload of staff and improving cultivation efficiency.
[0036] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
