Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, specifically to a vertical intelligent feeding device that mimics human feeding and its working method. Background Technology

[0002] Feeding is a key factor affecting aquaculture costs. With the upgrading of the domestic aquaculture industry, manual feeding alone is no longer sufficient to meet industry requirements, making intelligent feeding of farmed fish an urgent task. Existing feeding equipment typically uses a timed and quantitative strategy, but these devices cannot judge the feeding desire and movement trajectory of the fish in real time, lacking adaptive control of the feeding process. Currently, the solution to this problem usually involves manual feeding, observing the feeding process visually and strictly controlling the feeding location and rhythm. To promote the modernization and intelligent development of aquaculture, it is necessary to invent a method that can identify the movement trajectory of the fish in real time and control the feeding trajectory, achieving intelligent management and control of the aquaculture feeding process. Summary of the Invention

[0003] The purpose of this invention is to provide a vertical intelligent feeding device that mimics human feeding and its working method, so as to solve the problems existing in the prior art.

[0004] The objective of this invention is achieved as follows: a vertical intelligent feeding device that mimics human feeding, comprising:

[0005] The conveying silo has a fixed bottom foundation structure, which contains an automatic stirring component.

[0006] The lower end of the hopper is connected to the conveying hopper and faces the automatic mixing unit.

[0007] A vertical screw lifting device includes an upright feeding pipe and a conveying mechanism built into the feeding pipe to convey materials in the conveying bin from bottom to top. The automatic stirring component is used to drive the materials to the position of the conveying mechanism. The bottom of the feeding pipe is connected to the conveying bin.

[0008] A vertical material spreading disc device includes a frame connector that is detachably connected to a feeding pipe, a closed-loop stepper motor that is fixedly connected to the frame connector, and a material spreading disc body that is driven to rotate horizontally by the closed-loop stepper motor. The top of the feeding pipe is movably connected to the material spreading disc body, and the side of the material spreading disc body is provided with a diffuser for spreading material.

[0009] Furthermore, the spreading disc body has a spreading blade assembly built in it, and is equipped with a spreading power unit that drives the spreading blade assembly to rotate within the spreading disc body, thereby driving the material to be spread out from the diffuser.

[0010] Furthermore, the material spreading power unit is a high-speed DC motor, which is installed on the side wall of the material spreading disc. Its output end is connected to the material spreading blade assembly. The frame connector is equipped with a proximity switch, which is used to sense the high-speed DC motor. The position point of the proximity switch is set as the coordinate origin of the rotation trajectory of the material spreading disc.

[0011] Furthermore, a wide-angle camera is installed on the upper side of the diffuser of the feeding disc to capture the entire view of the fish pond and to adjust the feeding rate in real time.

[0012] Furthermore, a slanted tee is installed at the top of the feeding pipe. The slanted tee has a vertical pipe section and a downwardly sloping pipe section. The upper end of the vertical pipe section of the slanted tee is closed. The vertical pipe section of the slanted tee is connected to the feeding pipe. The slanted pipe section of the slanted tee is connected to a discharge pipe. The discharge pipe is connected to the spreading disc.

[0013] Furthermore, the main body of the feeding pipe is a vertical transparent PVC pipe.

[0014] Furthermore, the conveying mechanism includes:

[0015] A fixed-position lifting stepper motor;

[0016] An upright stainless steel screw is inserted into the feeding pipe and is connected to the output end of the lifting stepper motor.

[0017] Furthermore, the automatic stirring component is configured as a stirring disc rotatably connected to the conveying chamber, the output end of the lifting stepper motor is connected to the stirring disc for transmission, and the stainless steel screw rotates synchronously with the stirring disc.

[0018] Furthermore, the silo is equipped with a temperature and humidity sensor for detecting the temperature and humidity of the material.

[0019] As another aspect of the present invention, a working method using the above-described device is proposed, wherein the position of the feed falling into the fish pond is controlled by adjusting the feeding speed and rotation angle of the vertical feeding disc device.

[0020] The discharge rate is controlled by a stainless steel screw driven by a lifting stepper motor.

[0021] A wide-angle camera above the feeding tray is used to capture the entire fishpond to determine the feeding intensity of the fish and adjust the feeding rate in real time.

[0022] The beneficial effects of this invention are as follows:

[0023] This invention achieves the effect of bottom-mounted feed bins and high-level feeding through a vertically arranged screw arrangement. It also features a vertical feed tray, enabling customized feeding within the fishpond area. The feed dispensing speed can be adaptively adjusted according to the fish's appetite intensity, greatly reducing feed waste and improving feeding accuracy and uniformity. It has significant promotional value in the feeding of fish in factory-scale aquaculture. Attached Figure Description

[0037] The following will refer to the appendices in the embodiments of the present invention. Figure 1-7 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0038] Traditional fish feeders only use a timed and quantitative feeding method, which cannot adjust the feeding position and rate according to the feeding intensity of the fish and the position of the fish in the fish pond. This can easily lead to uneven feeding and serious size deviations in the fish.

[0039] like Figure 1-4 As shown, a vertical intelligent feeding device that mimics human feeding is proposed, comprising:

[0040] The bottom basic structure includes a chassis 1, an aluminum profile frame 3-23, and a base plate 3-24. It can be configured as a movable structure, in which the chassis 1 can be fixedly installed on the trolley assembly 5. The trolley assembly 5 has a push rod and several rollers, which can move the entire equipment to any position. The aluminum profile frame 3-23 is installed on the base plate 3-24 and is located inside the chassis 1.

[0041] The conveying chamber 3-11 has an aluminum profile frame 3-23 fixedly connected to its bottom. The conveying chamber 3-11 has an automatic stirring component built in, and the conveying chamber 3-11 is equipped with an openable and closable discharge cover 3-12.

[0042] The lower end of the hopper 3-8 is connected to the conveying hopper 3-11 and faces the automatic stirring component. The hopper 3-8 is equipped with a temperature and humidity sensor 3-7 for detecting the temperature and humidity of the material.

[0043] The vertical screw lifting device 3 includes an upright feeding pipe connected to the conveying chamber 3-11, and a conveying mechanism built into the feeding pipe to convey the material in the conveying chamber 3-11 from bottom to top. An automatic stirring component is used to drive the material to the position of the conveying mechanism. The bottom of the feeding pipe is connected to the conveying chamber 3-11.

[0044] The vertical spreading disc device 2 includes a frame connector 2-3 that can be detachably fitted with a feeding pipe (a part of the frame connector 2-3 is set as a clamp, which is used to detachably fix the feeding pipe with bolts), a closed-loop stepper motor 2-1 fixedly connected to the frame connector 2-3, and a spreading disc body 2-8 driven by the closed-loop stepper motor 2-1 to rotate horizontally. The spreading disc body 2-8 is a hollow shell and is located at a higher position above the housing 1. It is fixedly connected to the output spindle of the closed-loop stepper motor 2-1. The top of the feeding pipe is movably connected to the spreading disc body 2-8. The side of the spreading disc body 2-8 is provided with a diffuser 2-10 for spreading material. The diffuser 2-10 can be made into a trumpet shape or other structures.

[0045] The spreading disc 2-8 contains a spreading blade assembly 2-7, which has several blades. The surface of each blade is wavy. The spreading disc 2-8 is equipped with a spreading power unit that drives the spreading blade assembly 2-7 to rotate within the spreading disc 2-8, thereby driving the material to be spread out from the diffuser 2-10.

[0046] The above-mentioned material spreading power unit is a high-speed DC motor 2-5. The high-speed DC motor 2-5 is installed on the side wall of the material spreading disc 2-8, and its output end is connected to the material spreading blade group 2-7. The central axis of the high-speed DC motor 2-5 and the material spreading blade group 2-7 is arranged horizontally and perpendicular to the central axis of the closed-loop stepper motor 2-1.

[0047] As a waterproof design, the closed-loop stepper motor 2-1 is equipped with a stepper motor waterproof cover 2-2, which is a plastic shell; the high-speed DC motor 2-5 is equipped with a DC motor waterproof cover 2-6, which is a plastic shell; the above-mentioned waterproof covers can be made of other materials.

[0048] The frame connector 2-3 has a vertical fixing rod, and a proximity switch 2-4 is installed on the upper end of the vertical fixing rod. The proximity switch 2-4 is used to sense the high-speed DC motor 2-5. The position point of the proximity switch 2-4 is set as the coordinate origin of the horizontal rotation trajectory of the spreading disc 2-8 (used to zero the reference point of the closed-loop stepper motor 2-1) to prevent deviation of the horizontal rotation trajectory of the spreading disc 2-8, thereby more accurately controlling the angle of horizontal rotation of the spreading disc 2-8 and accurately controlling the landing position of the spreading material.

[0049] A wide-angle camera 2-9 is installed on the upper side of the diffuser 2-10 of the feed tray 2-8 for capturing the entire fishpond and for adjusting the feeding rate in real time.

[0050] like Figure 1 , 4As shown, a slanted tee 3-4 is installed at the top of the feeding pipe. The slanted tee 3-4 has a vertical pipe section and a downwardly sloping pipe section. A flange bearing 3-3 is installed at the upper end of the vertical pipe section of the slanted tee 3-4 and sealed with a top cover 3-2. The vertical pipe section of the slanted tee 3-4 is connected to the inner cavity of the feeding pipe. The slanted pipe section of the slanted tee 3-4 is connected to a drop pipe 3-1. The drop pipe 3-1 is connected downward to the opening on the upper side of the spreading disc 2-8. The opening on the upper side of the spreading disc 2-8 is a circular opening. The drop pipe 3-1 is a circular pipe structure. The drop port of the drop pipe 3-1 is circular and coaxial with the circular opening on the upper side of the spreading disc 2-8. While the spreading disc 2-8 rotates horizontally, the drop port of the drop pipe 3-1 and the circular opening on the upper side of the spreading disc 2-8 remain connected.

[0051] The main body of the above-mentioned feeding pipe is set as an upright transparent PVC pipe 3-5 so that the material conveying status can be clearly seen.

[0052] The aforementioned conveying mechanism includes:

[0053] A fixed lifting stepper motor 3-22 is provided, and a lifting motor base 3-20 is installed for the lifting stepper motor 3-22. The lifting motor base 3-20 is fixedly connected to an aluminum pad 3-21, and the aluminum pad 3-21 is fixedly connected to an aluminum profile frame 3-23, thereby fixing the position of the lifting stepper motor 3-22.

[0054] The upright stainless steel screw 3-6 is movably installed inside the feeding pipe and is connected to the output end of the lifting stepper motor 3-22.

[0055] The automatic stirring component built into the conveying bin 3-11 includes a stirring disc 3-14. The output end of the lifting stepper motor 3-22 is connected to the stirring disc 3-14 for driving the stirring disc 3-14 to rotate and stir, thereby driving the material to the position of the stainless steel screw 3-6. Since the same power unit - the lifting stepper motor 3-22 - is used, the stainless steel screw 3-6 and the stirring disc 3-14 rotate synchronously.

[0056] The upper side of the conveying chamber body 3-11 is provided as a conveying chamber cover 3-10, and the transparent PVC pipe 3-5 is fixedly connected to the conveying chamber cover 3-10 using a PVC inner thread seat 3-9.

[0057] The automatic stirring component built into the conveying bin 3-11 is a stirring plate 3-14 (the material discharge port of the hopper 3-8 faces downwards and is directly opposite the stirring plate 3-14). The stirring plate shaft 3-16 of the stirring plate 3-14 is rotatably connected to the conveying bin 3-11 through the stirring plate bearing 3-13. The stirring plate shaft 3-16 moves downwards and passes through the conveying bin 3-11. The stirring plate gear 3-15 is fitted at the lower end of the stirring plate shaft 3-16.

[0058] The output end of the lifting stepper motor 3-22 is connected to the screw shaft 3-18 via coupling 3-19. The screw shaft 3-18 is connected to the stainless steel screw 3-6. The screw shaft 3-18 is fitted with a screw gear 3-17, which meshes with the mixing disc gear 3-15, so that the output end of the lifting stepper motor 3-22 can drive the stainless steel screw 3-6 and the mixing disc 3-14 to rotate synchronously.

[0059] like Figure 5-6 As shown, the waterproof touchscreen 4 consists of a display housing 4-1, a waterproof insert plate 4-2, a touchscreen 4-3, and a touchscreen fixing component 4-4. The touchscreen 4-3 is provided with a sliding groove, which allows the waterproof insert plate 4-2 to slide into the groove from the side for assembly. The waterproof insert plate 4-2 is used to prevent water from entering the touchscreen 4-3.

[0060] During use, the feeding position in the fish pond is controlled by adjusting the feeding speed and rotation angle of the vertical feeding disc device 2. The feeding direction is controlled by the closed-loop stepper motor 2-1, and the feeding distance is controlled by the high-speed DC motor 2-5.

[0061] The discharge rate is controlled by a stainless steel screw 3-6 driven by a lifting stepper motor 3-22.

[0062] The wide-angle camera 2-9 above the feeding tray 2-8 is used to capture the entire fishpond to determine the feeding intensity of the fish and adjust the feeding rate in real time.

[0063] like Figure 7 As shown, the fish appetite classification model selection allows users to choose different deep learning models (such as CNN, ResNet50, MobileNetV3) to identify fish feeding behavior. The aquaculture parameter settings include configuration of environmental parameters such as fish density, size, pond size, water temperature, salinity, dissolved oxygen, and pH. The feeding parameter settings offer multiple feeding modes (single-point scattering, multi-point scattering, trajectory scattering, random trajectory) and allow users to set the feeding start time, interval, feed amount, and whether to enable intelligent feeding and its sensitivity. The network settings support networking via NB-IoT or ESP8266, and can also operate in offline mode.
