Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture, and in particular to a track-type bidirectional quantitative bait feeding device and a precise feeding method. Background Art

[0002] my country has become the world's largest fishery farming country. Feeding is an important task in the aquaculture process, and the efficiency and accuracy of feeding will directly affect the farming efficiency. Compared with the traditional pond farming model, the freshwater fish facility farming has a higher farming density and higher farming efficiency. Freshwater fish facility farming includes a variety of farming models such as pond enclosure, factory-scale recirculating water farming, and land-based circular pond farming. With the development and promotion of freshwater fish facility farming models, the farming scale under this model has gradually increased, and the farming output has continued to increase. However, there is a lack of feed feeding devices suitable for the facility farming model. The feed feeding process in the farming process is basically completed manually, which has low work efficiency, high farming costs, and low feed utilization. In addition, in the facility farming model, if the number of farming ponds or farming facilities is large and the types of farming objects are diverse, the traditional feed feeding devices and feeding methods are not sufficient to adapt to the above-mentioned farming model.

[0003] Current technology presents a problem: Freshwater fish farming currently relies primarily on manual feeding, which is labor-intensive and inefficient. Furthermore, manual feeding can lead to inaccurate feeding amounts, and overfeeding can cause water pollution. Freshwater fish aquaculture, a facility-based, high-density, intensive aquaculture model, demands high production efficiency. In recent years, the development of existing feeding devices in my country has primarily focused on traditional aquaculture models, such as large ponds. These devices are still in the semi-automated stage, suffering from shortcomings such as low automation, limited operability, and a limited range of applications. Currently, aquaculture models such as pond aquaculture, factory-scale recirculating aquaculture, and roadbed circular pond aquaculture share similar pond layouts. While a small number of feeding devices exist that are suitable for these models, most are complex, require large installation spaces, have high installation costs, low automation levels, and lack versatility. Consequently, existing feeding devices cannot simultaneously meet the feeding requirements of all of the aforementioned facility-based aquaculture models.

[0004] The device in the patent document (CN202223162902.4) is an I-shaped track installed indoors. Due to the high cost, the track needs to be installed in the air. It is suitable for factory-based breeding environments, but not for other facility-based breeding modes such as pond farming in outdoor environments. In addition, the two pairs of first- and second-level feeding mechanisms in the patent are both used to feed one breeding pond.

[0005] The difficulties in solving these problems are: 1) It is difficult to integrate the preparatory work before feeding bait in the limited space of the current freshwater fish facility farming model without human intervention; 2) For the neatly arranged breeding ponds in the freshwater fish facility farming environment, it is difficult to individually set the required feeding parameters for each breeding pond, identify the location of the feeding device and store data.

[0006] The significance of solving the above problems lies in the fact that compared with other bait feeding devices available on the market, it is necessary to develop a track-type bait feeding device and method with automatic identification of aquaculture ponds, bait quantification, and two-way bait feeding. It can realize the functions of temporary storage, transportation, and feeding of bait at a lower cost and in a compact space, which is of great significance for improving the efficient bait feeding in freshwater fish facility aquaculture and promoting aquaculture production efficiency.

A discharging screw mechanism, a first-level discharging motor and a second-level discharging motor, wherein the first-level discharging screw mechanism is provided in the first-level discharging mechanism, and the second-level discharging screw mechanism is provided in the second-level discharging mechanism. The first-level discharging mechanism is installed directly above the second-level discharging mechanism, and the lower end of the hopper is connected to the first-level discharging mechanism; the telescopic mechanism is installed at the main structure of the second-level discharging mechanism, and is used to push the second-level discharging mechanism out horizontally. When the second-level discharging mechanism is extended to the farthest end, the discharge port of the first-level discharging mechanism and the feed port of the second-level discharging mechanism are aligned; the walking drive mechanism is installed at the bottom of the frame, and is used to drive the feeding device to walk on the track.

[0014] Optionally, in the above-mentioned track-type bidirectional quantitative bait feeding device, the control unit includes a battery, a controller, a Hall sensor and a positioning magnet installed on a positioning magnet mounting plate located on the inner side of the track, the battery and the controller are installed at the bottom inner of the frame, and the Hall sensor is installed at the bottom outer of the frame.

[0015] Optionally, in the above-mentioned track-type two-way quantitative bait feeding device, the positioning magnet is arranged on the ground below the track.

[0016] Optionally, the above-mentioned track-type two-way quantitative bait feeding device further includes a touch screen arranged on the housing of the bait feeding device for providing a human-computer interaction function.

[0017] According to another aspect of the present invention, a method for precise feeding of the above-mentioned track-type bidirectional quantitative bait feeding device is provided, comprising the following steps: S1, numbering the culture ponds on both sides of the track, with every two culture ponds forming a unit, and the numbers of the multiple unit culture ponds being set as 1, 2, 3, etc., wherein the culture ponds on both sides are respectively determined as area A and area B; S2, installing the positioning magnets according to the unit numbers, such as setting a positioning magnet at unit No. 1, and assigning it as position No. 1 in the control program, and so on, multiple Hall sensors at different positions will generate corresponding permutations and combinations according to the setting of the positioning magnets; S3, determining the number of the culture pond unit to be fed and the relevant feeding parameters; S4, based on the determined number of the culture pond unit and the feeding parameters, first setting the operation of the device in the control unit.

[0022] 3) When feeding bait, the present invention uses multiple Hall sensors in conjunction with multiple positioning magnets in different positions and combinations to accurately identify the position of the breeding pond, which can efficiently and quickly complete the position of the breeding pond to be fed.

[0032] To make the purpose, technical methods and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings and specific examples. These examples are merely illustrative and not intended to limit the present invention.

[0033] like Figure 1 The application scenario of the track-type two-way quantitative bait feeding device of the present invention is shown in FIG. Figure 1 As shown in the figure, the breeding ponds 1 are neatly arranged, with a diameter of 4m and a distance of 1m between each pond. The spacing of the running tracks 3 is set to 0.8m. The tracks 3 are set in the empty space between two rows of breeding ponds 1. A positioning magnet mounting plate 4 is installed in the middle of each group of breeding ponds 1 to provide a reference for the position identification of the feeding device 2. When the feeding device is working, it runs on the track and automatically identifies the position of the breeding pond 1 to be fed according to the set feeding parameters, and feeds the breeding ponds 1 on both sides. Under normal circumstances, the feeding of the breeding ponds 1 on both sides does not interfere with each other because the feeding device of the present invention actually has two feeding mechanisms. The above structure can maximize the reduction of space utilization on the breeding platform.

[0034] like Figure 1 and Figure 3 The track-type two-way quantitative bait feeding device of the present invention comprises a track 3, a positioning magnet mounting plate 4 arranged on the inner side of the track 3, a bait feeding device 2 arranged on the track 3 and capable of moving on the track 3, and a control unit, wherein, as Figure 3 As shown, the feeding device 2 includes a frame, a material injection port 11, a material storage mechanism, a material feeding mechanism, a telescopic mechanism and a travel drive mechanism, wherein:

[0035] The storage mechanism includes two silos 14 of the same size and symmetrically distributed around the center and four weighing sensors 12. The silos 14 are fixed to the frame through the weighing sensors 12. The lower end of the silo 14 is connected to the first-level discharge mechanism 6.

[0036] The feeding mechanism includes a primary discharging mechanism 6, a primary discharging mechanism discharging port 25, a secondary discharging mechanism 7, a secondary discharging mechanism feeding port 26 and a secondary discharging mechanism discharging port 27, a primary discharging screw mechanism 16, a secondary discharging screw mechanism 18, a primary discharging motor 15 and a secondary discharging motor 17, wherein a spiral mechanism is provided in the discharging mechanism. Specifically, a primary discharging screw mechanism 16 is provided in the primary discharging mechanism 6, and a secondary discharging screw mechanism 18 is provided in the secondary discharging mechanism 7. The primary discharging mechanism 6 is installed directly above the secondary discharging mechanism 7. The primary discharging mechanism 6 is used to discharge the bait in the hopper 14, and the secondary discharging mechanism 7 is used to transport the discharged bait into the breeding pond 1; the secondary discharging motor 17 drives the secondary discharging screw mechanism 18 to rotate, so as to transport the bait delivered by the primary discharging mechanism 6 and feed it into the breeding pond 1;

[0037] The telescopic mechanism includes a telescopic push rod, a guide rail 8 and a slider. The telescopic push rod, the guide rail 8 and the slider are all installed on the main structure of the secondary discharging mechanism 7, and are used to push the secondary discharging mechanism 7 horizontally to feed the above-mentioned bait into the breeding pond; the push rod motor 19 is arranged at the bottom of the secondary discharging mechanism 7 and is connected to the top of the telescopic push rod through a fixing part. When feeding, the push rod motor 19 pushes the secondary discharging mechanism 7 out, and drives the secondary discharging mechanism 7 to retract into the inside of the feeding device 2 when not feeding.

[0038] Figure 5 It is a structural diagram of the two-stage discharging mechanism in the track-type bidirectional quantitative bait feeding device of the present invention, wherein the hopper 14, the first-level discharging mechanism 6 and the first-level discharging mechanism discharge port 25 are fixed relative to the main body of the feeding device 2, and the second-level discharging mechanism 7, the second-level discharging mechanism feed port 26 and the second-level discharging mechanism discharge port 27 can realize the telescopic function as a whole. Since the available free space in the breeding environment is relatively small, the design of this part not only saves space but also allows the bait fed by the equipment to fall into the breeding pond. The working principle is as follows: before the device starts feeding, the secondary discharging mechanism 7 is first extended by the telescopic push rod. When it is extended to the farthest end, the telescopic push rod limit switch is triggered. At this time, the discharge port 25 of the primary discharging mechanism and the feed port 26 of the secondary discharging mechanism are just aligned. Then the spiral in the secondary discharging mechanism 7 (the secondary discharging spiral mechanism 18) starts to rotate first, and the primary discharging mechanism 6 starts to work to transport the bait from the hopper 14 to the breeding pond 1; when the feeding amount reaches the set value, the primary discharging mechanism 6 stops working, and then the secondary discharging mechanism 7 stops working.

[0039] The travel drive mechanism includes a travel drive motor 10, a transmission chain 21, and travel wheels 22. The travel drive motor 10 is mounted on the inner bottom of the frame. The travel wheels 22 are used to travel on the track 3 and are mounted on the outer bottom of the frame and connected to the travel drive motor 10 via the transmission chain 21. The travel drive motor 10 is used to drive the entire bait feeding device 2 to travel on the track 3.

[0040] The control unit includes a battery 9, a controller 20, a Hall sensor 24 ( Figure 4 As shown) and the positioning magnet 5 (as shown) mounted on the positioning magnet mounting plate 4 located on the inner side of the track 3 Figure 2 As shown), the battery 9 and the controller 20 are installed at the bottom inside the frame, the Hall sensor 21 is installed at the bottom outside the frame of the bait feeding device 2, and the positioning magnet 5 is arranged on the ground below the track 3 to control the movement and positioning of the bait feeding device 2.

[0041] The touch screen 13 is arranged on the outer shell of the feeding device 2 (the outer shell is not shown in the figure), located on the wide side and close to the upper part of the feeding device 2, and is used to provide human-computer interaction functions. Feeding parameters can be set, feeding data can be recorded, and historical feeding data can be viewed on the touch screen 13.

[0042] The number of magnets and the installation position of the magnets are different in different breeding ponds, which are used to define the number of breeding ponds 1-n in the control system ( Figure 1 The numbers of the pools 1 to 8 are 1-1, 1-2; 2-1, 2-2... pools. Identifying one pool can complete the position identification and bait feeding of the two opposing pools in the program according to the feeding mechanism on both sides); 4 Hall sensors are installed at the feeding device, such as Figure 4 As shown, the bait feeding device is the same as the above Figure 2 The installation diagram of the Hall effect sensors 24 corresponding to the positioning magnets 5 is numbered 1-4 from one side to the other, but the number and number of magnets recognized at each position are also different. For example, the positioning magnet 5 corresponding to the passage of sensor No. 1 is arranged in advance at pool No. 1-1(2); and the positioning magnet 5 corresponding to sensor No. 2 is arranged at pool No. 2-2(2). Four sensors can recognize a total of 15 positions, and a total of 30 breeding pools can be set up. The number of sensors can be changed.

[0043] The track-type bidirectional quantitative bait feeding device of the present invention does not have a secondary silo, and the structure is simpler and more direct. There is no secondary weighing, and the second-stage spiral conveying device is used to put the bait into the breeding pond; the walking mechanism of the device can be modified into a transport vehicle when the adult fish are harvested; and the bait can be fed to two independent breeding ponds.

[0044] The method for accurately feeding the track-type two-way quantitative bait feeding device of the present invention comprises the following steps:

[0045] S1. Number the aquaculture ponds on both sides of the track, with every two aquaculture ponds forming a unit. Multiple unit aquaculture ponds are numbered 1, 2, 3, etc., wherein the aquaculture ponds on both sides are respectively designated as Area A and Area B;

[0046] S2. Install the positioning magnet according to the unit number. For example, a positioning magnet is set at unit 1, and it is assigned as position 1 in the control program. Similarly, multiple Hall sensors at different positions will generate corresponding permutations and combinations according to the setting of the positioning magnet. Taking a 1-unit breeding pond as an example, when the feeding device moves on the track and recognizes unit 1, the corresponding two feeding units in the feeding device are responsible for feeding the bait to the breeding ponds on both sides, and perform data calculation and storage separately. Finally, the data of a single breeding pond is presented. In this embodiment, four Hall sensors are used as an example.

[0047] S3, determine the number of the aquaculture pond unit to be fed and related feeding parameters;

[0048] S4. Based on the number and feeding parameters of the culture pond units, the operating time of the device is first set in the control unit, and then the feed feeding amount for each culture pond is set respectively based on the above-mentioned area A and area B;

[0049] S5. During the feeding process, the feeding weight of each culture pond is calculated by subtracting the weighing data of the weighing sensor, and the difference is regarded as the feeding amount of each culture pond; preferably, before feeding, the walking mechanism drives the feeding device to move to the culture pond to be fed, and after the device stops, the telescopic mechanism first pushes out the secondary discharging mechanism, and then the secondary discharging motor starts to rotate, and the last-stage discharging motor starts to feed the bait in the silo into the culture pond;

[0050] S6. The feeding device feeds each pond in sequence along the track according to the pond number and feeding parameters. After feeding is completed in all ponds, the feeding device returns to its initial position. Preferably, the control unit identifies the last pond to be fed and returns to its initial position after feeding is completed. A set of positioning magnets is also installed at the initial position, and the control unit defaults to this initial position.

[0051] Working principle:

[0052] When the feeding device confirms the working task, the walking drive mechanism transmits power to the bottom through the designed chain transmission method, driving the entire device to move. At the same time, a Hall sensor is installed at the bottom of the device. In conjunction with the induction magnet installed in the venue, the device can accurately identify its current position and move to the target fish pond.

[0053] After reaching the target fish pond, the upper storage mechanism, located at the top of the device, is equipped with a pressure sensor. It fills the device with bait through two top-mounted injection ports, and the pressure sensor measures the bait mass within the mechanism. A primary discharge mechanism is connected below the upper storage mechanism to prevent the bait from leaking out. During operation, the mechanism uses an internal transmission mechanism to transport the bait from the storage mechanism and into the secondary discharge mechanism. Filling takes place at the initial position, rather than at the target fish pond. Once the device reaches the target fish pond, it can begin a subtractive process of discharging and feeding the bait.

[0054] A telescopic mechanism is installed at the bottom of the secondary discharging mechanism, and is fixed to the middle part of the entire device through the telescopic mechanism. After reaching the target position, the telescopic mechanism pushes the entire secondary discharging mechanism outward, so that the secondary discharging mechanism is fully extended. After the telescopic mechanism is completed, the primary discharging mechanism will transport the bait in the storage mechanism out. The bait will fall into the secondary discharging mechanism from the opening below the primary discharging mechanism through the feed port of the secondary discharging mechanism. The bait will then be transported outward through the spiral structure in the secondary discharging mechanism, so that the bait falls out from the outermost opening, thus achieving the feeding of bait in the breeding pond. After the feeding of the bait is completed, the telescopic mechanism at the lower end drives the secondary discharging mechanism to retract, and then the device moves to the next target breeding pond to feed the bait until all the feeding work is completed. Among them, the secondary discharging mechanism is in a retracted state when the device is moving to prevent the device from colliding during the movement.

[0055] In addition, the upper feeding mechanism (including the storage mechanism, the feeding mechanism and the telescopic mechanism) and the walking mechanism (including the walking drive mechanism and the control unit) can be designed separately and then matched together. When the adult fish are taken out, they can be used as a transportation device, so that one machine has multiple uses.

[0056] The key points of the present invention are:

[0057] 1. The track-type two-way quantitative feeding device is in line with the existing freshwater fish facility farming models and needs, such as pond farming, factory-scale recirculating aquaculture and land-based circular pond farming. It can automatically complete the precise identification of the positions of multiple neatly arranged breeding ponds and the quantitative feeding of bait, and can simultaneously feed the breeding ponds on both sides with quantitative bait.

[0058] 2. The feeding device uses a Hall sensor in combination with multiple positioning magnets in different positions and combinations to accurately identify the position of the breeding pond. Compared with general sensors, this sensor has the characteristics of wide measurement range, high measurement accuracy and adaptability to relatively harsh working environments. It can be better applied to freshwater fish facility breeding environments.

[0059] 3. The feeding device adopts a two-stage discharging method, in which the second-stage discharging mechanism can be extended and retracted by a telescopic mechanism. It extends when feeding bait and retracts when in the walking state, which improves the space utilization rate in the breeding environment and the safety of the equipment during use to a certain extent.

[0060] The above description is the best embodiment based on the concept and working principle of the invention. The above embodiment should not be understood as limiting the scope of protection of the present claims. Other embodiments and combinations of implementations of the present invention are also within the scope of protection of the present invention.
