[0068] The present invention will be further described below with specific embodiments:

[0069] The present embodiment provides a feeding device for a shrimp pond, wherein the shrimp pond is used for culturing shrimps. The basic function of the feeding device of the present embodiment is to feed the shrimp pond 6 to feed the shrimps in the shrimp pond 6.

[0070] See also Figure 1 The feeding device of this embodiment mainly consists of two parts, namely, a liquid medicine supply device 1 and a feed supply device 2.

[0071] The function of the drug solution supply device 1 is to prepare a drug solution capable of treating shrimp diseases using a pre-prepared drug, and to provide the prepared drug solution to the feed supply device 2 .

[0072] The function of the feed supply device 2 is to put the pre-prepared feed into the shrimp pond 6 to feed the shrimps cultured in the shrimp pond 6, and selectively mix the medicine provided by the medicine supply device 1 into the put feed. In other words, the feed supply device 2 can not only put in normal feed, but also mix the "medicine provided by the medicine supply device 1" into the feed and then put it in.

[0073] In addition, in this embodiment, a camera 3 is provided at the inner bottom of the shrimp pond 6, and the camera 3 is mainly used to observe the state of the shrimp, such as the body shape and body color of the shrimp. When the camera 3 detects that the shrimp is sick, it makes a judgment based on the specific symptoms of the shrimp and selects a solution for adding the drug.

[0074] Specifically,

[0075] See also Figure 2 The liquid medicine supply device 1 includes four dispensing sub-devices 11 , and the specific preparation of the liquid medicine is completed by these four dispensing sub-devices 11 .

[0076] More specifically, see Figure 3 ,

[0077] The medicine dispensing sub-device 11 mainly includes a medicine box 112 and a medicine liquid box 117 , which are arranged up and down, with the medicine box 112 being located at the top and the medicine liquid box 117 being located at the bottom of the medicine box 112 .

[0078] The medicine box 112 has an upper opening and a lower opening. The upper opening serves as a medicine adding opening for the staff to put pre-prepared medicine into the medicine box 112, and the lower opening serves as a lower medicine opening connected to the medicine liquid tank 117. Under the action of gravity, the medicine in the medicine box 112 can fall into the medicine liquid tank 117 through its lower medicine opening.

[0079] At the medicine lowering port of the medicine box 112 , or in other words, at the connection point between the medicine box 112 and the medicine liquid box 117 , a medicine lowering valve 115 is provided to control the amount of medicine dropped from the medicine box 112 into the medicine liquid box 117 .

[0080] The liquid medicine tank 117 is also provided with a water adding pump 111 and a liquid suction pump 116. The water adding pump 111 is used to draw water for preparation of medicine from a pre-equipped water supply source to the liquid medicine tank 117. The water for preparation of medicine and the medicine are fully mixed in the liquid medicine tank 117 to form a finished liquid medicine. The liquid suction pump 116 is used to extract the liquid medicine in the liquid medicine tank 117 and supply it to the outside (supply it to the outside through the liquid medicine supply pipe, which will be described in detail later).

[0081] In addition, a plurality of photosensitive sensors 113 are provided on the inner side of the medicine box 112 . These photosensitive sensors 113 are dispersedly arranged in the height direction to detect the remaining amount of medicine stored in the medicine box 112 .

[0082] The liquid medicine supply device 1 further comprises a manifold joint 18, which is a many-to-one pipe connection piece in the prior art, and has four inlet pipe openings and one outlet pipe opening, and the four inlet pipe openings are all connected to the outlet pipe opening.

[0083] The water outlets of the suction pumps 116 of the four medicine dispensing sub-devices 11 are respectively connected to the four access pipe openings of the manifold joint 18, and the output pipe opening of the manifold joint 18 serves as the medicine liquid supply pipe opening of the entire medicine liquid supply device 1 to provide the prepared medicine liquid to the feed supply device 2.

[0084] In summary, the four medicine dispensing sub-devices 11 provide the prepared medicine liquid to the feed supply device 2 through the manifold joint 18; the suction pump 116 in the medicine dispensing sub-device 11 can draw the medicine liquid in the medicine liquid tank 117 to the medicine liquid supply pipe port, and provide the medicine liquid to the feed supply device 2 through the medicine liquid supply pipe port.

[0085] In addition, in order to prevent the liquid medicine from flowing back, a one-way valve 19 is provided at the output pipe opening of the manifold joint 18 .

[0086] In other embodiments, other forms of drug dispensing sub-devices 11 may also be used as long as they can achieve specific drug liquid configuration.

[0087] It should be noted that in this embodiment, four dispensing sub-devices 11 are used, and these four dispensing sub-devices 11 are used to prepare intestinal regulating, liver protecting, sterilizing, and appetite inducing drugs, that is, the drug boxes 112 of the four dispensing sub-devices 11 are respectively placed with intestinal regulating drugs, liver protecting drugs, sterilizing drugs, and appetite inducing drugs (different drugs are placed in each drug box 112). In other embodiments, the specific number of dispensing sub-devices 11 can be set according to the specific drug liquid category requirements (one dispensing sub-device 11 is for one drug).

[0088] It should be noted that in other embodiments, other forms of liquid medicine supply devices 1 may also be used, as long as they can achieve the function of "using pre-prepared medicines to prepare liquid medicine that can treat shrimp diseases, and providing the prepared liquid medicine to the feed supply device 2", and the present invention is not limited to this.

[0089] See also Figure 4 The feed supply device 2 mainly includes two feed bins 202 and a storage bin 209. The two feed bins 202 are both located at the top, and the storage bin 209 is located below the two feed bins 202.

[0090] There are two feed silos 202, one of which is used as a medicated feed silo, and the other is used as a common feed silo.

[0091] The main structure of the two feed bins 202 is roughly the same, with an upper opening and a lower opening. The upper opening serves as a feed inlet for the staff to put pre-prepared feed into the feed bin 202, and the lower opening serves as a discharge port connected to the storage bin 209. Under the action of gravity, the feed in the feed bin 202 can fall into the storage bin 209 through its discharge port.

[0092] At the discharge port of the feed bin 202 , or in other words, at the connection point between the feed bin 202 and the storage bin 209 , a discharge valve 208 is provided to control the amount of feed falling from the feed bin 202 into the storage bin 209 .

[0093] A stirrer 207 is also provided in the feed bin 202 . The stirrer 207 is driven by a stirring motor 204 to stir the feed placed in the feed bin 202 .

[0094] The difference between the medicated feed bin and the ordinary feed bin is that: a dosing nozzle 203 connecting the inside and the outside is arranged on the top of the medicated feed bin, and the liquid medicine supply nozzle of the liquid medicine supply device 1 mentioned above (i.e., the output nozzle of the manifold joint 18) is connected to the dosing nozzle 203 through a section of pipeline. In other words, the liquid medicine supply nozzle of the liquid medicine supply device 1 is connected to the medicated feed bin via the dosing nozzle 203, and the liquid medicine provided by the liquid medicine supply device 1 is actually introduced into the medicated feed bin, so that the liquid medicine is mixed into the feed placed in the medicated feed bin.

[0095] In summary, the drug adding nozzle 203 serves as the drug liquid receiving nozzle of the entire feed supply device 2 and is connected to the drug liquid supply nozzle of the drug liquid supply device 1 , thereby receiving the drug liquid provided by the drug liquid supply device 1 .

[0096] In addition, a drying fan 210 is provided for the medicated feed bin, and the hot air outlet of the drying fan 210 is connected to the feed bin 202 through a pipeline to dry the feed mixed with the medicated liquid in the feed bin 202 .

[0097] It should be noted that, in order to evenly distribute the liquid medicine in the medicated feed bin, a spray head is also provided at the medicated feed nozzle 203, and the spray head is located in the medicated feed bin.

[0098] The storage bin 209 has two openings, which are respectively used as an air outlet 2091 and a feed outlet 2092. The air outlet 2091 is connected to a feed fan 201, and the feed outlet 2092 is connected to the shrimp pond 6 through a pipeline. In this way, the running feed fan 201 can form an airflow from the air outlet 2091 to the feed outlet 2092 in the storage bin 209. Driven by the airflow, the feed in the storage bin 209 can be discharged from the feed outlet 2092 and reach the shrimp pond 6 along the pipeline, that is, the pneumatic conveying method is used to convey the put feed to realize feeding the shrimps cultured in the shrimp pond 6.

[0099] The feed driving port 2092 of the storage bin 209 actually serves as a feed supply pipe port of the entire feed supply device 2 to provide feed to the shrimp pond 6.

[0100] It should be noted that, in this embodiment, the number of feed bins 202 included in the feed supply device 2 is two, one as a medicated feed bin and the other as a common feed bin. However, in other embodiments, the number of feed bins 202 can be set according to demand, and only one feed bin 202 can be set as a medicated feed bin, or more than two feed bins 202 can be set, and some or all of them can be used as medicated feed bins, while the other feed bins 202 can be used as common feed bins; similar combinations are possible, and the present invention is not limited to this.

[0101] See also Figure 4 Since the shrimp culture pond 6 involved in this embodiment is not one but multiple, the feed supply pipe port of the feed supply device 2 is not directly connected to the shrimp culture pond 6, but a pipeline conversion distribution mechanism 7 is set at the feed supply pipe port of the feed supply device 2, and the feed supply pipe port of the feed supply device 2 is connected to multiple different shrimp culture ponds 6 through the pipeline conversion distribution mechanism 7. The function of the pipeline conversion distribution mechanism 7 is to distribute the feed output from the feed supply pipe port of the feed supply device 2 to multiple pipelines leading to different shrimp culture ponds 6. In other words, the feed supply pipe port of the feed supply device 2 is connected to multiple different shrimp culture ponds 6 via the pipeline conversion distribution mechanism 7. Thereby, feed supply to multiple different shrimp culture ponds 6 is realized.

[0102] See also Figure 5 Specifically, the pipeline conversion distribution mechanism 7 includes a main distribution transfer pipe 72, a sub-distribution transfer pipe 76 and a main distribution plate 77.

[0103] The main distribution transfer pipe 72 and the sub-distribution transfer pipe 76 have the same configuration, but are different in size. The configuration is a three-stage eccentric configuration.

[0104] The so-called "three-section eccentric configuration" means that the pipe is divided into three sections. The left and right sections where the pipe openings at both ends are located are parallel to each other and the axes deviate by a certain distance. The middle section is inclined to connect the left and right sections.

[0105] For the convenience of description, both ends of the main distribution transfer pipe 72 and the sub-distribution transfer pipe 76 are referred to as a first end and a second end, respectively.

[0106] The first end of the main distribution rotating pipe 72 is rotatably connected to the feed supply pipe opening of the feed supply device 2 (i.e., the feed drive opening 2092 of the storage bin 209). A rotation drive motor is also provided for the first end of the main distribution rotating pipe 72, and the rotation drive motor is called the main distribution motor 73. The main distribution motor 73 is used to drive the main distribution rotating pipe 72 to rotate based on the feed supply pipe opening of the feed supply device 2.

[0107] The second end of the main distribution rotating pipe 72 is rotatably connected to the first end of the sub-distribution rotating pipe 76. A rotation drive motor is also provided for the first end of the sub-distribution rotating pipe 76, and the rotation drive motor is called the sub-distribution motor 75. The sub-distribution motor 75 is used to drive the sub-distribution rotating pipe 76 to rotate based on the second end of the main distribution rotating pipe 72.

[0108] See also Figure 6 The main distribution plate 77 is in a disc shape as a whole. For the convenience of description, the two sides of the main distribution plate 77 are respectively referred to as the pool-facing surface and the pool-rearward surface.

[0109] Four connecting pipe areas 771 are provided on the main distribution plate 77, and four connecting pipe holes 772 are provided in each connecting pipe area 771. The connecting pipe holes 772 penetrate the two sides (the pool surface and the back pool surface) of the main distribution plate 77.

[0110] The four connecting pipe areas 771 of the main distribution disk 77 are evenly and discretely distributed along the circumference of the entire main distribution disk 77 . In each connecting pipe area 771 , the four connecting pipe holes 772 in the connecting pipe area 771 are evenly and discretely distributed along the circumference of the connecting pipe area 771 .

[0111] The main distribution plate 77 is arranged beside the second end pipe opening of the sub-distribution rotating pipe 76, and the back pool surface of the main distribution plate 77 faces the second end pipe opening of the sub-distribution rotating pipe 76;

[0112] When the main distribution rotating pipe 72 rotates based on the feed supply pipe opening of the feed supply device 2, the sub-distribution rotating pipe 76 can pass through each receiving area 771 of the main distribution plate 77;

[0113] When the sub-distribution rotating pipe 76 is in a connecting pipe area 771 of the main distribution plate 77 , the sub-distribution rotating pipe 76 rotates based on the second end pipe mouth of the main distribution rotating pipe 72 so that the second end pipe mouth of the sub-distribution rotating pipe 76 can pass through each connecting pipe hole 772 in the connecting pipe area 771 .

[0114] In addition, a quick connection mechanism is provided for each connection hole 772 at the back surface of the main distribution plate 77, so that the second end of the sub-distribution transfer pipe 76 can be quickly connected to any connection hole 772 through the quick connection mechanism.

[0115] In addition, a sub-distribution plate 78 is provided for each pipe connection area 771 on the pool surface of the main distribution plate 77, and a pipe joint is provided on the sub-distribution plate 78 for each pipe connection hole 772. For the convenience of description, these pipe joints are referred to as shrimp pond pipe joints 781.

[0116] In the pipeline conversion and distribution mechanism 7, a shrimp pond feed pipe 4 is configured corresponding to each shrimp pond 6. For each shrimp pond feed pipe 4, one end of the pipe mouth is connected to a shrimp pond pipe joint 781 as a feed inlet, and the other end of the pipe mouth is placed above the corresponding shrimp pond 6 as a feed inlet.

[0117] In this way, the previously mentioned "the feed supply pipe opening of the feed supply device 2 is connected to a plurality of different shrimp farming ponds 6 via the pipeline conversion distribution mechanism 7" is achieved.

[0118] In addition, a throwing hose 5 is also provided at the feeding port of the shrimp pond feeding pipe 4. Since the feed is delivered to the feeding port of the shrimp pond feeding pipe 4 by the feed supply device 2 through pneumatic conveying, when the high-speed airflow is output from the feeding port of the shrimp pond feeding pipe 4, the throwing hose 5 can swing with the airflow, thereby achieving the effect of swinging and throwing the feed. Moreover, by controlling the size of the airflow of the pneumatic conveying, the swing amplitude of the throwing hose 5 can also be controlled, thereby controlling the radius of the swinging and throwing feed.

[0119] It should be noted that, in this embodiment, the number of pipe connection areas 771 provided on the main distribution plate 77 is four, and the number of pipe connection holes 772 provided in each pipe connection area 771 is four, which can correspond to 16 shrimp farming ponds 6 at most, that is, feed can be put into 16 shrimp farming ponds 6. However, in other embodiments, the specific number of pipe connection areas 771 and pipe connection holes 772 can be determined according to the actual number of shrimp farming ponds 6, and the present invention is not limited to this.

[0120] It should be noted that the feeding device of this embodiment is arranged at a position far away from the shrimp pond 6, that is, the feeding device and the shrimp pond 6 are arranged separately, and the feeding device is placed in a dry environment to avoid corrosion by water vapor.

[0121] The feeding device of this embodiment is also equipped with a feeding control system, and the liquid medicine supply device 1, the feed supply device 2 and the pipeline conversion distribution mechanism 7 are all controlled by the feeding control system. In addition, the feeding control system is also connected to the camera 3 in the shrimp pond 6, so as to receive the image signal captured by the camera 3. The feeding control system is mainly used to control the coordinated operation of the liquid medicine supply device 1, the feed supply device 2 and the pipeline conversion distribution mechanism 7 (the electrical equipment therein) to achieve the process control of feeding. In the process of feeding, the feeding of feed can also be controlled according to the image of the shrimp in the shrimp pond 6 captured by the camera 3.

[0122] Specifically,

[0123] The feeding control system can be used to set a single feeding duration, and the feeding amount can be controlled by controlling the feeding duration. The distance between the shrimp pond 6 and the feed supply device 2 can be known from the ID number of the shrimp pond 6, and the appropriate fan frequency and fan working time can be determined.

[0124] The feeding control system is provided with an on-demand feeding control algorithm program. Based on the on-demand feeding control algorithm program, the feeding control system can control the entire feeding device to realize intelligent on-demand feeding of feed for the shrimp pond 6.

[0125] The feeding control system is arranged in a control box beside the feed supply device 2 .

[0126] About Camera 3,

[0127] When the camera 3 detects that the shrimp is sick, it makes a judgment based on the specific symptoms of the shrimp and selects a dosing solution plan. The dosing solution plan includes photos of the sick shrimp, the corresponding medicine, the mass of the medicine to be added, and the mass of the water. The plan is sent to the staff, who can confirm or modify the plan. After the dosing solution plan is determined, the medicine dispensing valve 115 and the water pump 111 in the medicine dispensing sub-device 11 are automatically opened, the amount of medicine in the medicine box 112 is reduced, and the photosensitive sensors 113 at different positions send signals. According to the signal of the photosensitive sensor 113, the amount of medicine is indirectly calculated. When the amount of medicine is equal to the mass of the medicine to be added in the dosing solution plan, the medicine dispensing valve 115 is closed; the mass of water added to the medicine box 112 is calculated according to the opening time of the water pump 111. When the amount of water is equal to the mass of water to be added in the dosing solution plan, the water pump 111 is closed. Water and medicine are mixed in the medicine liquid tank 117, and the medicine liquid is configured. After the preparation of the liquid medicine is completed, the liquid suction pump 116 is turned on, and the liquid amount is controlled by controlling the opening and closing time of the liquid suction pump 116.

[0128] Regarding the state of the prawns captured by camera 3,

[0129] When the first and second step of the shrimp is photographed with faster swing speed and obvious action of grabbing food, it means that the shrimp has a strong desire to eat, and the feeding machine should be started to start feeding. When the shrimp body color is abnormal and the jejunum and stomach are empty, it means that the shrimp is sick. According to the body shape of the shrimp photographed, the cause of the shrimp disease is determined, and the proportion of the number of sick shrimp in the group is calculated to calculate the required amount of medicine. After determining the solution addition plan, when feeding the feed, first turn on the suction pump 116 of the corresponding drug dispensing sub-device 11 and the stirrer 207 in the drug-dosing feed bin, put in a specified amount of medicine and mix it with the feed evenly, turn on the drying fan 210, the liquid medicine adheres to the feed, and then start feeding.

[0130] Regarding the medicated feed bin mentioned earlier,

[0131] The medicated feed bin is suitable for feeding shrimps when they are sick. A spray head is arranged at the dosing pipe port 203 in the medicated feed bin, and the drug liquid is evenly sprayed into the medicated feed bin through the spray head. At the same time, the stirrer 207 is started to evenly mix the drug liquid and the feed. After the drug liquid is added to a specified amount, the suction pump 116 of the drug dispensing sub-device 11 is turned off, and the drying fan 210 is turned on to make the drug liquid adhere to the feed.

[0132] Regarding the ordinary feed silo mentioned earlier,

[0133] The common feed bin is suitable for feeding shrimps under normal conditions. Starting the agitator 207 can prevent feed from accumulating and forming cavities in the common feed bin.

[0134] The feeding device of this embodiment has the following specific working principle:

[0135] The medicine dispensing sub-device 11 in the medicine liquid supply device 1 mixes water and medicine to form medicine liquid, and the medicine liquid supply device 1 supplies the medicine liquid to the feed supply device 2 through the medicine liquid supply pipe port. In the feed supply device 2, the feed supply device 2 introduces the received medicine liquid into the medicine feed bin ( Figure 4 The feed bin 202 on the middle right side) is a medicated feed bin that mixes the liquid medicine with the feed and then drops it into the storage bin 209. The feeding fan 201 is turned on and runs to apply strong wind to the storage bin 209, thereby forming a high-speed airflow in the storage bin 209 and in the subsequent feed conveying pipeline, thereby achieving the effect of pneumatic conveying of the feed. Under the pneumatic conveying condition, the feed in the storage bin 209 reaches the pipeline conversion and distribution mechanism 7 via the feed supply pipe port (feed driving port 2092) of the feed supply device 2. Before delivering the feed, the pipeline conversion and distribution mechanism 7 pre-converts and adjusts the path for distributing the feed so that the feed conveying path points to the target shrimp pond 6 for feeding the feed. The feed under pneumatic conveying reaches the target shrimp pond 6 directly through the adjusted feed conveying path, thereby achieving the feeding of the shrimp pond 6.

[0136] In addition, the swing amplitude of the spreading hose 5 can be controlled by controlling the airflow size of the pneumatic conveying, so that the radius of the swing spreading feed can be controlled.

[0137] The feeding control system can realize the coordinated control of the entire feeding process.

[0140] 2) In the feeding device of this embodiment, the feed supply pipe port of the feed supply device 2 is connected to a plurality of different shrimp farming ponds 6 through a pipeline conversion distribution mechanism 7, and the pipeline conversion distribution mechanism 7 distributes the feed output from the feed supply pipe port of the feed supply device 2 to a plurality of different shrimp farming ponds 6, thereby solving the problem 2) mentioned in the background technology that "the current feeding machine cannot feed multiple shrimp farming ponds";

[0141] 3) In the feeding device of this embodiment, a throwing hose 5 is also provided at the feeding port of the shrimp pond feeding pipe 4. By controlling the airflow size of the pneumatic conveying, the swing amplitude of the throwing hose 5 can be controlled, so that the radius of the swing throwing feed can be controlled, thereby solving the problem 3) mentioned in the background technology that "the current feeding machine cannot adjust the feed throwing range";

[0142] 4) The feeding device of this embodiment is equipped with a feeding control system, which can control the coordinated operation of the entire feeding device to achieve full process control of feed delivery and can realize intelligent on-demand feeding of feed, thereby solving the problem 4) mentioned in the background technology that "the current feeding machine cannot realize intelligent on-demand feeding".
