In the modern shrimp and fish farming industry, with the continuous expansion of the aquaculture scale and the increasing development of aquaculture technology, the refined management and precise feeding of shrimp and fish farming have become increasingly important. Shrimp and fish at different growth stages have different requirements for the amount and nutritional components of feed. Accurately sorting and weighing feed can ensure that shrimp and fish obtain sufficient and appropriate nutrition, promote their growth and development, improve the survival rate and yield of shrimp and fish, and at the same time avoid feed waste and reduce aquaculture costs.

[0003] Traditional feed sorting and weighing methods mostly rely on manual operation, which has problems such as low efficiency and large errors, and it is difficult to meet the needs of large-scale and standardized aquaculture. Although some farms have adopted automated feed weighing equipment, existing equipment usually only has a single conveying device. When sorting feeds of different weight specifications, either the weighing accuracy is insufficient due to excessive conveying volume, or the working efficiency is affected due to too slow conveying speed.

Detailed implementation manners

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0046] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0047] Please refer to Figures 1 to 11, an intelligent feed sorting and weighing device provided by an embodiment of the present invention. The intelligent feed sorting and weighing device includes: a support frame 1, on which three laterally distributed feed pipes 11 are fixedly installed. Feed inlets 111 and discharge outlets 112 are provided on the three feed pipes 11. A screw conveyor 12 is rotatably connected in each of the three feed pipes 11. A storage bucket 13 with its bottom communicating with the feed inlet 111 is fixedly installed on the support frame 1. A weighing and tipping mechanism 5 for weighing the materials falling from the discharge outlet 112 is installed at the discharge outlet 112. A driving mechanism 2 for driving the screw conveyor 12 to rotate is installed at the rear side of the support frame 1. A control panel 6 is installed on the weighing and tipping mechanism 5. A controller 7 is installed on the support frame 1; The driving mechanism 2 includes a driving motor 22. An installation plate 21 is fixedly installed at the rear side of the support frame 1, and the driving motor 22 for driving the screw conveyor 12 to rotate is installed on the installation plate 21. The output end of the driving motor 22 is fixedly installed with a driving shaft 23, and a docking cylinder 24 is installed at the end of the driving shaft 23. The end of the feed pipe 11 is rotatably connected with a rotating block 25 fixed and coaxial with the screw conveyor 12, and a cross docking groove 251 is provided on the rotating block 25. A cross docking block 26 that can be inserted into the cross docking groove 251 is fixedly installed at the end of the docking cylinder 24. A cross sliding cavity 241 is provided inside the docking cylinder 24, and a cross slider 27 is slidably connected in the cross sliding cavity 241. A spring 28 compressed by the cross slider 27 is installed in the cross sliding cavity 241. The driving shaft 23 is slidably connected with the docking cylinder 24 and its end is fixedly connected with the cross slider 27. A docking mechanism 3 for controlling the docking and clamping of the cross docking block 26 into the cross docking groove 251 is installed on the installation plate 21. A transverse movement mechanism 4 for controlling the lateral movement of the driving motor 22 is also installed on the installation plate 21.

[0048] It should be noted that: In the present invention, the storage barrel 13 is used to store fish and shrimp feed. The storage barrel 13 is equipped with a corresponding barrel cover. The weight data of the feed to be taken out is input through the control panel 6, and the signal is transmitted to the controller 7. The controller 7 then controls the transverse movement mechanism 4 to move the driving motor 22 to the position of the corresponding auger 12 with a larger feed conveying amount. The docking mechanism 3 controls the driving motor 22 to move towards the rotating block 25 on the corresponding auger 12 until the cross docking block 26 on the docking cylinder 24 is inserted into the cross docking groove 251 on the corresponding rotating block 25. The driving motor 22 can then drive the corresponding auger 12 to rotate. When the cross docking block 26 is not fully inserted into the cross docking groove 251, the docking cylinder 24 will be squeezed, causing the cross slider 27 to slide in the cross sliding cavity 241 and squeeze the spring 28. When the driving motor 22 rotates, the cross docking block 26 will slowly rotate accordingly. When the cross docking block 26 rotates to the position of the cross docking groove 251, under the elastic force of the spring 28, the cross docking block 26 will be fully inserted into the cross docking groove 251, thus realizing the docking of the docking cylinder 24 and the corresponding rotating block 25. The driving motor 22 will drive the corresponding auger 12 to rotate for the feeding operation. As the auger 12 rotates, the feed in the storage barrel 13 will enter the feed pipe 11 from the feed inlet 111 and be conveyed by the rotating auger 12, and fall from the discharge outlet 112 into the weighing and tipping mechanism 5 to be received. When the weight of the feed weighed in the weighing and tipping mechanism 5 reaches the maximum amount conveyed by the auger 12 with a larger feed conveying amount (that is, when the auger 12 continues to rotate, the amount of conveyed feed will exceed the specified weight of the feed), the docking mechanism 3 controls the driving motor 22 to retract, so that the cross docking block 26 disengages from the cross docking groove 251 on the corresponding rotating block 25. The transverse movement mechanism 4 then controls the driving motor 22 to move to the position of the auger 12 with a smaller conveying amount. The docking mechanism 3 controls the docking cylinder 24 on the driving motor 22 to dock with the rotating block 25 connected to the corresponding auger 12 with a smaller conveying amount, and drives the auger 12 with a smaller conveying amount to rotate for the feeding and discharging operation. When the weight of the feed weighed in the weighing and tipping mechanism 5 reaches the maximum amount conveyed by the auger 12 with a smaller conveying amount, the driving motor 22 is then docked and driven with the auger 12 with the smallest conveying amount until the weight of the feed weighed in the weighing and tipping mechanism 5 meets the requirements, and the driving motor 22 stops working. The container for receiving the feed in the weighing and tipping mechanism 5 flips, and then other containers can be used to receive and take the feed; through the cooperation of the controller 7, the weighing and tipping mechanism 5 and the augers 12 with different conveying amounts, the present invention first quickly feeds the feed by the auger 12 with a larger feed conveying amount, switches to the auger 12 with a smaller conveying amount when approaching the specified weight, and finally precisely supplements with the auger 12 with the smallest conveying amount, which can accurately control the weight of the feed, meet the scenarios with precise requirements for the amount of feed, and avoid waste or shortage of feed;After the input data is entered into the control panel 6, the signal is transmitted to the controller 7. The controller 7 automatically controls the operation of components such as the transverse movement mechanism 4, the docking mechanism 3, and the drive motor 22, realizing the automation of a series of operations from the docking of the drive motor 22 with different augers 12, the rotational feeding of the augers 12 to the weighing of the weighing and tipping mechanism 5, reducing manual intervention, improving work efficiency, and reducing labor costs and human errors.

[0049] Among them, the ratio of the material conveying amounts of the three augers 12 located in the three feed pipes 11 is 1:10:100. This setting allows the device to first use the auger 12 with a large conveying amount to quickly approach the target weight during weighing, and then use the auger 12 with a smaller conveying amount for precise adjustment. For example, by first starting the auger with a 100-fold conveying amount, a large amount of feed can be conveyed in a short time to quickly reach a state close to the target weight, and then the auger with a 10-fold conveying amount is used to further approach the target, and finally the auger with a 1-fold conveying amount is used for fine adjustment, thus greatly improving the weighing efficiency and reducing the time required for weighing.

[0050] Among them, the notch of the cross docking groove 251 and the cross docking block 26 are both chamfered, and the end of the cross docking block 26 is in a tapered shape. The cross docking block 26 with a tapered end is like an accurate "navigator", which can automatically guide and align with the notch of the cross docking groove 251 during the docking process. The chamfered setting further broadens the docking tolerance space, enabling the docking cylinder 24 and the rotating block 25 to still complete the docking relatively easily when there is a certain angular deviation or position error, greatly reducing the difficulty of the docking operation and improving the efficiency of the quick and accurate connection between the drive motor 22 and the auger 12.

[0051] Among them, the model of the drive motor 22 is: 40KTYZ synchronous motor, with good stability.

[0052] Furthermore, it can be connected through a wireless network. Managers can remotely log in to the device control system using a mobile phone APP or computer software to realize operations such as remote start, stop, and parameter setting of the device. For example, when the farm manager is away, they can also adjust the feed weighing parameters and control the device operation according to actual needs at any time.

[0053] In the embodiment of the present invention, please refer to Figure 7 and Figure 8 , the docking mechanism 3 includes a transverse movement plate 31. The transverse movement plate 31 is slidably connected to the mounting plate 21, and a support block 32 is slidably connected to the transverse movement plate 31. The drive motor 22 is slidably connected to the transverse movement plate 31 through the support block 32. A telescopic cylinder 33 for controlling the telescopic movement of the drive motor 22 is fixedly installed on the transverse movement plate 31, and the output end of the telescopic cylinder 33 is fixedly connected to the support block 32 through a telescopic rod 34.

[0054] It should be noted that: the telescopic cylinder 33 on the transverse moving plate 31 controls the telescopic movement of the telescopic rod 34, so as to realize the telescopic operation of the driving motor 22 fixedly installed on the supporting block 32, that is, the docking cylinder 24 is docked with the corresponding auger 12;

[0055] Among them, the model of the telescopic cylinder 33 is: CDQ2 thin rod guide cylinder, which has good directivity and high telescopic accuracy.

[0056] Among them, a limiting sliding groove 311 is opened on the transverse moving plate 31, and a limiting sliding block 321 fixed to the bottom of the supporting block 32 is slidably connected in the limiting sliding groove 311; during the movement of the supporting block 32, the limiting sliding block 321 slides in the limiting sliding groove 311, improving the stability of the movement of the supporting block 32, thereby improving the docking accuracy between the docking cylinder 24 and the corresponding rotating block 25.

[0057] In the embodiment of the present invention, please refer to Figure 6 、 Figure 7 and Figure 9 As shown in, the transverse moving mechanism 4 includes a transverse moving cylinder 43, the transverse moving cylinder 43 is horizontally and fixedly installed at the bottom of the mounting plate 21, and the output end of the transverse moving cylinder 43 is fixedly installed with a transverse moving piston rod 44. The end of the transverse moving piston rod 44 is fixedly connected with a fixing block 42. A transverse strip-shaped sliding cavity 211 is opened on the mounting plate 21, and a connecting block 41 fixed to the bottom of the transverse moving plate 31 is slidably connected in the strip-shaped sliding cavity 211. The connecting block 41 is fixedly connected with the end of the transverse moving piston rod 44 through the fixing block 42;

[0058] It should be noted that: the transverse moving cylinder 43 controls the telescopic movement of the transverse moving piston rod 44, so as to control the connecting block 41 connected through the fixing block 42 to slide in the strip-shaped sliding cavity 211, adjust the position of the transverse moving plate 31, and displace the docking cylinder 24 to the position of the corresponding rotating block 25;

[0059] Among them, the number of the strip-shaped sliding cavities 211 opened on the mounting plate 21 is two, and a connecting block 41 is slidably connected in each of the two strip-shaped sliding cavities 211. The two connecting blocks 41 are fixedly connected through the fixing block 42, and the fixing block 42 is slidably connected with the lower side wall of the mounting plate 21; the two fixing blocks 42 slide in the two strip-shaped sliding cavities 211 respectively, which can improve the transverse movement stability of the transverse moving plate 31, thereby improving the overall stability of the device;

[0060] Among them, the model of the transverse moving cylinder 43 is: CDQ2 thin rod guide cylinder, which has good directivity and high transverse movement accuracy.

[0061] In the embodiment of the present invention, please refer to Figure 1 、 Figure 2 and Figure 3, the weighing and tipping mechanism 5 includes a housing 51, which is fixedly installed on the support frame 1 and communicated with the discharge port 112. A weighing plate 52 is rotatably connected inside the housing 51. A receiving box 53 is also installed on the weighing plate 52. A weighing sensor is installed between the weighing plate 52 and the receiving box 53. A tipping motor 54 is fixedly installed on the outer wall of the housing 51, and the output end of the tipping motor 54 is coaxially and fixedly connected to the rotating connection of the weighing plate 52;

[0062] It should be noted that: the feed falling from the discharge port 112 will directly fall into the receiving box 53. The weighing sensor at the bottom of the receiving box 53 monitors the weight of the feed received in the receiving box 53 in real time. When the weight of the feed in the receiving box 53 reaches the requirement, the tipping motor 54 outside the housing 51 will control the receiving box 53 on the weighing plate 52 to tip, and perform the feeding operation on the received feed. After all the feed in the receiving box 53 is poured out, the tipping motor 54 will control the receiving box 53 to rotate to the initial position;

[0063] Among them, the model of the tipping motor 54 is: 57 spiral linear screw stepper motor, which can achieve stable forward and reverse rotation and meet the tipping requirements of the feed receiving box 53;

[0064] Among them, the size of the upper opening of the housing 51 is smaller than the cavity size of the receiving box 53; the receiving box 53 can receive the feed discharged from the discharge port 112 and prevent it from falling out.

[0065] In the embodiment of the present invention, please refer to Figure 2 , a reinforcing plate 8 is fixedly installed on the housing 51, and the reinforcing plate 8 is fixed to the support frame 1 by bolts;

[0066] It should be noted that: the weighing and tipping mechanism 5 needs to receive a relatively heavy weight of feed, and it itself also has a relatively large weight. By setting the reinforcing plate 8, the stability of the weighing and tipping mechanism 5 is improved.

[0067] Among them, the control panel 6 can be selected with the model: Kunlun Tongtai TPC7062KX, which has high cost performance, supports multiple communication protocols, and is convenient to connect with other devices;

[0068] The controller 7 can be selected with the model: Mitsubishi FX3U, which has rich instructions and flexible programming, can meet different control logic requirements, and realizes precise control of each component of the equipment.

[0069] The working principle of the intelligent feed sorting and weighing equipment provided by the present invention is as follows:

[0070] In the present invention, the storage bin 13 is used to store fish and shrimp feed. The storage bin 13 is equipped with a corresponding bucket cover. The weight data of the feed to be taken out is input through the control panel 6, and the signal is transmitted to the controller 7. The controller 7 then controls the transverse movement mechanism 4. The transverse movement cylinder 43 controls the telescopic movement of the transverse movement piston rod 44, so as to control the sliding of the connecting block 41 connected through the fixing block 42 in the strip-shaped sliding cavity 211, adjust the position of the transverse movement plate 31, and move the driving motor 22 to the position of the auger 12 with a larger feed conveying amount. The telescopic cylinder 33 on the transverse movement plate 31 controls the telescopic rod 34 to extend, so that the driving motor 22 moves towards the rotating block 25 on the corresponding auger 12 until the cross docking block 26 on the docking cylinder 24 is inserted into the cross docking groove 251 on the corresponding rotating block 25. The driving motor 22 can then drive the corresponding auger 12 to rotate. When the cross docking block 26 is not fully inserted into the cross docking groove 251, the docking cylinder 24 will be squeezed, so that the cross slider 27 slides in the cross sliding cavity 241 to squeeze the spring 28. When the driving motor 22 rotates, the cross docking block 26 will rotate slowly. When the cross docking block 26 rotates to the cross docking groove 251, under the elastic force of the spring 28, the cross docking block 26 will be fully inserted into the cross docking groove 251, so as to realize the docking of the docking cylinder 24 and the corresponding rotating block 25. The driving motor 22 will drive the corresponding auger 12 to rotate for feeding. As the auger 12 rotates, the feed in the storage bin 13 will enter the feed pipe 11 from the feed inlet 111 and be conveyed by the rotating auger 12, and fall from the discharge port 112 into the receiving box 53 in the weighing and flipping mechanism 5 to be received. When the weighing sensor at the bottom of the receiving box 53 weighs up to the maximum amount conveyed by the auger 12 with a larger feed conveying amount (that is, when the auger 12 continues to rotate, the conveyed feed amount will exceed the specified weight of the feed), the telescopic cylinder 33 controls the driving motor 22 to retract, so that the cross docking block 26 disengages from the cross docking groove 251 on the corresponding rotating block 25. The transverse movement cylinder 43 then controls the driving motor 22 to move to the position of the auger 12 with a smaller conveying amount. The telescopic cylinder 33 controls the docking cylinder 24 on the driving motor 22 to be docked with the rotating block 25 connected to the corresponding auger 12 with a smaller conveying amount, and drives the auger 12 with a smaller conveying amount to rotate for feeding and discharging operation. When the weighing sensor at the bottom of the receiving box 53 weighs up to the maximum amount conveyed by the auger 12 with a smaller feed conveying amount, the driving motor 22 is then docked and driven with the auger 12 with the smallest conveying amount until the weight of the feed weighed in the receiving box 53 reaches the requirement. The driving motor 22 stops working. The flipping motor 54 outside the housing 51 will control the receiving box 53 on the weighing plate 52 to flip for discharging the received feed, and then other containers can be used to receive and take the feed. After all the feed in the receiving box 53 is poured out, the flipping motor 54 will control the receiving box 53 to rotate to the initial position;In the present invention, through the cooperation of the controller 7, the weighing and tipping mechanism 5, and the augers 12 with different conveying capacities, first, the auger 12 with a larger feed conveying capacity is used for rapid feeding. When approaching the specified weight, the auger 12 with a smaller conveying capacity is switched to, and finally, the auger 12 with the smallest conveying capacity is used for precise supplementation. It can accurately control the weight of the feed, meet the scenarios with precise requirements for the feed quantity, and avoid waste or shortage of the feed. After the data is input through the control panel 6, the signal is transmitted to the controller 7, and the controller 7 automatically controls the operation of components such as the transverse movement mechanism 4, the docking mechanism 3, and the drive motor 22, realizing the automation of a series of operations from the docking of the drive motor 22 with different augers 12, the rotational feeding of the augers 12 to the weighing of the weighing and tipping mechanism 5, reducing manual intervention, improving work efficiency, and reducing labor costs and human errors.

[0071] A control method for an intelligent feed sorting and weighing device includes the following steps:

[0072] S1: Initialization stage:

[0073] Input the required feed weight parameters through the control panel 6 and start the device control system;

[0074] S2: Rapid feeding operation:

[0075] The controller 7 selects the auger 12 with the maximum conveying capacity according to the preset parameters, and makes the auger 12 start to rotate through the drive mechanism for rapid feeding;

[0076] S3: Approach target adjustment:

[0077] When the weighing sensor in the weighing and tipping mechanism 5 detects approaching the preset weight, the controller 7 switches to the auger 12 with a medium conveying capacity to continue feeding;
