Description

Technical Field

[0001] This invention relates to the field of feed distribution technology, and in particular to a zoned quantitative feed distribution device. Background Technology

[0002] In aquaculture and livestock farming, traditional feeding methods often involve manual scattering or single-pipe delivery, which is not only inefficient but also results in poor feed distribution uniformity, easily leading to significant differences in the growth of farmed organisms. With technological advancements, zoned quantitative feeding devices are widely used in large-scale farming scenarios to improve feed utilization and reduce size differences among farmed organisms. By distributing feed in preset amounts to different farming zones, these devices solve the problems of uneven feed distribution, significant waste, and large differences in the growth of farmed organisms associated with traditional feeding methods.

[0003] However, some of the zoned quantitative feeding devices used in existing aquaculture have insufficient range of feeding direction adjustment, are difficult to maintain stable coverage after adjustment on a floating platform, and have slow zone switching, which makes it easy for fish to crowd and compete for food, making them inconvenient to use. Summary of the Invention

[0007] The above technical solution employs the following: the internal sealed chamber structure of the feeding float (HDPE material) ensures the device floats on the water surface without leakage risk; the propulsion blades (nylon material) at the bottom of the feeding support are driven by a waterproof motor, which can move the device along a preset path; one end of the zone positioning rope (polyester material) is fixed to the support, and the other end is connected to the positioning stake on the shore of the aquaculture area to limit the feeding range; the rotating trough at the bottom of the feeding bin provides a rotation reference for the discharge hopper, and the trough wall is lined with a PTFE wear-resistant layer; the HDPE float is resistant to corrosion in aquaculture water; and the inert gas filling stabilizes buoyancy, ensuring the device does not capsize in wind and waves; the waterproof motor of the propulsion blades is adapted to the underwater environment and can drive the device to move at a constant speed; together with the zone positioning rope, zoned feeding is achieved within the aquaculture area to avoid feed concentration; the polyester material of the zone positioning rope is aging-resistant, limits the movement range, and prevents the device from deviating from the aquaculture area; and the PTFE layer of the rotating trough of the feeding bin reduces the rotational resistance of the discharge hopper, avoids metal wear, and extends service life.

[0008] Preferably, in any of the above embodiments, the discharge hopper includes a discharge motor connected to a microprocessor signal and a feeding seat for discharging bait. The discharge motor is fixedly installed at the bottom of the feeding bin, and the output end of the discharge motor is fixedly installed with the feeding seat that rotates inside the feeding bin. One end of the feeding seat is provided with a discharge pipe that penetrates the feeding bin. Waterproof sealing strips are provided on both sides of the discharge pipe that are fixedly installed with the feeding seat and rotate inside the feeding bin. Locking bosses that engage with the feeding seat are provided on both sides of the output end of the discharge motor.

[0009] The above technical solution is as follows: the discharge motor (waterproof stepper motor, connected to the microprocessor signal) of the discharge hopper is fixed at the center of the bottom of the feeding chamber. The output shaft is connected to the feeding seat through a coupling. The surface of the feeding seat has a cone-shaped feeding groove. An inclined discharge pipe is welded to one end. A waterproof sealing strip is fixed to both sides of the feeding seat and fits against the inner wall of the rotating groove of the feeding chamber to achieve rotational sealing. The locking bosses on both sides of the motor output end engage with the grooves of the feeding seat to ensure that the power transmission is non-slip. The stepper control of the discharge motor enables the feeding seat to rotate precisely and can control the amount of feed per revolution to adapt to different feeding needs. The feeding groove of the feeding seat stores a fixed amount of feed to ensure that the amount of feed per revolution is uniform. The inclined design of the discharge pipe allows the feed to slide smoothly and avoid blockage. The waterproof sealing strip can prevent water and feed debris from entering the rotating groove, protecting the motor and rotating structure. The locking bosses prevent the feeding seat and the motor output shaft from sliding relative to each other, ensuring power transmission efficiency.

[0010] Preferably, in any of the above embodiments, the feeding baffle includes an electric telescopic rod connected to a microprocessor signal and a baffle plate that blocks the bait. The electric telescopic rod is fixedly installed inside the feeding seat, and a baffle plate that moves inside the feeding seat is fixedly installed at one end of the electric telescopic rod.

[0011] The above technical solution is adopted as follows: the electric telescopic rod (miniature waterproof electric push rod, connected to the microprocessor signal) of the feeding baffle is fixed to the side wall of the feeding trough of the feeding seat, and the baffle plate is welded to the output end of the telescopic rod. It can slide along the side wall of the feeding trough to adjust the feeding state. The waterproof design of the electric telescopic rod is suitable for the humid environment of the feeding chamber. The stroke adjustment can change the position of the baffle plate, thereby adjusting the feeding amount and realizing graded control of the feeding amount. It is suitable for different sizes of aquaculture organisms. The stainless steel material of the baffle plate is resistant to feed corrosion, and the rigid structure ensures the stability of the position after adjustment, avoids the volume deviation caused by feed compression, and ensures the smooth movement of the baffle plate.

[0012] Preferably, in any of the above embodiments, the protective end cap is fixedly installed on the top of the feeding bin by threads, and the bottom of the protective end cap is provided with a detection groove for fixing a laser rangefinder sensor.

[0013] The above technical solution is adopted as follows: the protective end cap is connected to the top of the feeding bin by threads, and a feeding port (with a threaded cap) is opened on the surface. The detection groove at the bottom is located on one side of the center of the end cap and is used to fix the laser rangefinder sensor. The groove wall is covered with a rubber buffer pad. The threaded connection ensures that the end cap and the feeding bin are tightly sealed and can be quickly disassembled for easy replenishment of bait and internal maintenance of the feeding bin. The feeding port facilitates the addition of bait. The threaded cap prevents bait from splashing and rainwater from entering during feeding. The detection groove accurately fixes the laser rangefinder sensor to ensure that the detection direction is perpendicular to the pressure plate. The rubber buffer pad can absorb sensor vibration and avoid fluctuations in detection data.

[0014] Preferably, in any of the above embodiments, the pressing sheet includes a suspended detection line and a lightweight material sheet that rises and falls with the bait. The detection line is fixedly installed at the bottom of the protective end cap, and a lightweight material sheet located below the protective end cap is fixedly installed at the bottom of the detection line.

[0015] The above technical solution is adopted as follows: one end of the detection line (nylon line) of the pressing sheet is tied to the hook at the bottom of the protective end cap, and the other end is connected to the lightweight material sheet. The lightweight material sheet (PP material) is horizontally suspended inside the feeding chamber, floating on the surface of the bait, and descends synchronously as the amount of bait decreases. The surface of the material sheet is sprayed with a reflective coating to facilitate detection by the laser rangefinder sensor. The nylon material of the detection line is resistant to bait corrosion, and its low elasticity coefficient ensures accurate detection of the material sheet position. The lightweight material sheet is lightweight and can move flexibly with the rise and fall of the bait surface without compacting the bait. The reflective coating enhances the laser reflection signal, ensuring that the laser rangefinder sensor can still detect accurately in dim environments. The horizontal structure of the material sheet ensures that the detection position represents the average height of the bait and avoids misjudgment of the remaining amount caused by local protrusions.

[0016] Preferably, of any of the above solutions, the alarm light is fixedly installed on the top of the protective end cap, and the laser rangefinder is located on one side of the detection line and above the lightweight sheet.

[0017] The above technical solution is adopted as follows: The alarm light (LED three-color alarm light, connected to the microprocessor signal) is fixed to the top of the protective end cap by a bracket, and can emit three colors of light: red, yellow and green (red light: insufficient bait, yellow light: low balance reminder, green light: normal). The laser range sensor (infrared type, connected to the microprocessor signal) is fixed to the detection slot at the bottom of the protective end cap, with the detection end pointing vertically downward, located on one side of the detection line and directly above the lightweight material piece. The three-color light of the alarm light can intuitively reflect the status of the device, which is convenient for operators to observe from a distance. The LED light source has a long life and low power consumption, and is compatible with the device's battery power supply. The high-precision detection of the laser range sensor can accurately capture the slight displacement of the lightweight material piece and provide real-time feedback on the remaining bait. The sensor position design can avoid the detection line from blocking the laser and ensure the stability of the detection signal.

[0018] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0019] 1. A rotating discharge hopper is installed at the bottom of the feeding bin for storing bait. By controlling the position of the feeding baffle inside the discharge hopper, bait can be fed into the fishpond. During the feeding process, controlling the rotation of the discharge hopper allows for circular feeding with the feeding float as the center, increasing the feeding range and area, and facilitating the distribution of bait in a specific area. At the same time, the laser range sensor installed at the bottom of the protective end cover detects the positional changes of the pressing plate. Combined with the inherent dimensions of the feeding bin, the amount of bait can be determined, improving the accuracy and convenience of feeding.

[0020] 2. The pressing plate is set to rise and fall with the amount of bait. The laser range sensor can detect the pressing plate in real time to judge the amount of bait used and the remaining amount. The alarm light is controlled according to the remaining amount to make it easy to detect the lack of bait and replenish it in time, which is conducive to continuous and stable feeding.

[0021] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0030] like Figure 1-5As shown, an embodiment of the present invention provides a zoned quantitative feeding device, comprising a feeding float 1 floating on the water surface, feeding brackets 2 fixedly installed at both ends of the feeding float 1 for support and fixation, a feeding bin 3 for storing bait fixedly installed inside the feeding brackets 2, a rotatable discharge hopper 4 fixedly installed at the bottom of the feeding bin 3, a feeding partition 5 fixedly installed at the top of the discharge hopper 4, a protective end cap 6 for sealing the top of the feeding bin 3, a pressing plate 7 fixedly installed in the middle of the protective end cap 6 that rises and falls with the bait under the action of gravity, a laser rangefinder 8 for detecting the position of the pressing plate 7 and fixed inside the protective end cap 6, the center distance between the laser rangefinder 8 and the pressing plate 7 being less than the working radius of the pressing plate 7, a microprocessor for signal processing and automatic control connected to the laser rangefinder 8, a time relay for setting the feeding time inside the microprocessor, and an alarm light 9 for early warning connected to the microprocessor.

[0031] Preferably, in any of the above schemes, the interior of the feeding float 1 is a sealed chamber, the bottom of the feeding support 2 is equipped with a motor-driven propulsion blade, and above the propulsion blade is a partition positioning rope fixedly installed with the feeding support 2. The bottom of the feeding bin 3 is provided with a rotating groove for installing the discharge hopper 4. The feeding bin 3 consists of a connecting base fixed to the feeding support 2 and a sleeve fixed to the connecting base. The top center of the connecting base is provided with a central connecting rod that passes through the discharge hopper 4 to fix and support the sleeve.

[0032] The above technical solution is adopted as follows: The internal sealed chamber structure of the feeding float 1 (HDPE material) ensures that the device floats on the water surface without leakage risk. The propulsion blades (nylon material) at the bottom of the feeding support 2 are driven by a waterproof motor, which can move the device along a preset path. One end of the partition positioning rope (polyester material) is fixed to the support, and the other end is connected to the positioning stake on the shore of the aquaculture area to limit the feeding range. The rotating groove at the bottom of the feeding bin 3 provides a rotation reference for the discharge hopper 4. The groove wall is lined with a PTFE wear-resistant layer. The HDPE float is resistant to corrosion in aquaculture water. The inert gas filling stabilizes the buoyancy and ensures that the device will not capsize in wind and waves. The waterproof motor of the propulsion blade is adapted to the underwater environment and can drive the device to move at a constant speed. With the partition positioning rope, partition feeding is realized in the aquaculture area to avoid feed concentration. The polyester material of the partition positioning rope is aging resistant, limits the movement range, and prevents the device from deviating from the aquaculture area. The PTFE layer of the rotating groove of the feeding bin reduces the rotation resistance of the discharge hopper, avoids metal wear, and extends the service life.

[0033] The feeding float 1 is based on Archimedes' principle of buoyancy. The low density of the inert gas allows the entire float to float on the water surface. The propulsion blades are based on the principle of hydrodynamics. The motor drives the blades to rotate, generating thrust and moving the device. The zone positioning rope limits the movement trajectory of the device through mechanical limits, ensuring that the feeding covers the preset zone. The rotating trough, through its circular structure and wear-resistant layer, provides 360° rotation space for the discharge hopper, reducing friction loss. Before use, fix one end of the zone positioning rope to the feeding bracket 2 and the other end to the positioning stake on the shore of the aquaculture area to ensure that the device's movement range covers the target zone. Check the airtightness of the feeding float 1 to confirm that there is no leakage of inert gas. In case of leakage, after the device is started, the propeller motor starts, driving the device to move slowly along the path defined by the positioning rope. When feeding, the discharge hopper 4 rotates in the rotating trough to feed. During the movement of the device, the feed is covered in the entire section. After feeding is finished, the motor reverses and the device returns to the initial position. The positioning rope is retracted with the device. The microprocessor controls the speed of the propeller motor through the PWM signal to adjust the moving speed. The positioning rope tension sensor is set. When the tension exceeds the threshold (such as when encountering an obstacle), the motor stops and an alarm is triggered. The airtightness of the float is checked regularly, and inert gas is added. The PTFE layer of the rotating trough is cleaned regularly to remove feed residue and ensure smooth rotation.

[0034] Preferably, in any of the above embodiments, the discharge hopper 4 includes a discharge motor 41 connected to a microprocessor signal and a feeding seat 42 for discharging bait. The discharge motor 41 is fixedly installed at the bottom of the feeding bin 3. The output end of the discharge motor 41 is fixedly installed with the feeding seat 42, which rotates inside the feeding bin 3. One end of the feeding seat 42 is provided with a discharge pipe that penetrates the feeding bin 3. Waterproof sealing strips are provided on both sides of the discharge pipe, which are fixedly installed with the feeding seat 42 and rotate inside the feeding bin 3. Locking bosses that engage with the feeding seat 42 are provided on both sides of the output end of the discharge motor 41.

[0035] The above technical solution is adopted as follows: the discharge motor 41 (waterproof stepper motor, connected to the microprocessor signal) of the discharge hopper 4 is fixed at the bottom center of the feeding bin 3. The output shaft is connected to the feeding seat 42 through a coupling. The feeding seat 42 has a cone-shaped bait groove on its surface. An inclined discharge pipe is welded to one end. The waterproof sealing strip is fixed to both sides of the feeding seat 42 and fits against the inner wall of the rotating groove of the feeding bin 3 to achieve rotational sealing. The locking bosses on both sides of the motor output end are engaged with the grooves of the feeding seat 42 to ensure that the power transmission is non-slip. The stepping control of the discharge motor 41 enables the feeding seat 42 to rotate precisely and can control the amount of bait per revolution to adapt to different feeding needs. The bait groove of the feeding seat stores a fixed amount of bait to ensure that the amount of bait per revolution is uniform. The inclined design of the discharge pipe allows the bait to slide smoothly and avoid blockage. The waterproof sealing strip can prevent water and bait debris from entering the rotating groove, protecting the motor and rotating structure. The locking bosses prevent the feeding seat and the motor output shaft from sliding relative to each other and ensure power transmission efficiency.

[0036] The discharge motor 41 is based on the electromagnetic stepping principle. The microprocessor sends pulse signals to control the motor's rotation angle, driving the feeding seat 42 to rotate at a preset angle. The feeding seat's feed trough rotates to receive the feed and then rotates to the discharge pipe position. The feed is discharged through the discharge pipe under gravity. The waterproof sealing strip adheres to the inner wall of the rotating trough through elastic deformation, forming a dynamic seal to block water and impurities. The locking boss transmits motor torque through mechanical engagement to prevent slippage. Before feeding, the microprocessor calculates the rotation speed of the discharge motor 41 according to the required feeding amount. After feeding is started, the motor rotates at the preset angle. The motor rotates rapidly, causing the feeding seat 42 to rotate. The feed in the feeding bin 3 falls into the feeding seat's feeding trough. When the feeding trough rotates to the position of the discharge pipe, the feed slides down the discharge pipe at an angle and is fed into the breeding area. During the rotation, the waterproof sealing strip always adheres to the inner wall of the rotating trough to prevent water from entering. After the feeding amount reaches the target, the motor stops, and the feeding seat returns to its initial position. The microprocessor controls the rotation angle of the feeding seat through pulse counting to achieve precise control of the feeding amount. The feeding seat's feeding trough is disassembled and cleaned regularly to remove residual feed. The wear of the waterproof sealing strip is checked regularly to ensure the sealing effect.

[0037] Preferably, in any of the above solutions, the feeding partition 5 includes an electric telescopic rod 51 connected to a microprocessor signal and a baffle plate 52 for blocking the bait. The electric telescopic rod 51 is fixedly installed inside the feeding seat 42, and one end of the electric telescopic rod 51 is fixedly installed with the baffle plate 52 that moves inside the feeding seat 42.

[0038] The above technical solution is adopted: the electric telescopic rod 51 (miniature waterproof electric push rod, connected to the microprocessor signal) of the feeding partition 5 is fixed to the side wall of the feeding trough of the feeding seat 42, and the baffle plate 52 is welded to the output end of the telescopic rod. It can slide along the side wall of the feeding trough to adjust the feeding state. The waterproof design of the electric telescopic rod 51 is suitable for the humid environment of the feeding chamber. The stroke adjustment can change the position of the baffle plate 52, thereby adjusting the feeding amount and realizing graded control of the feeding amount to adapt to different sizes of aquaculture organisms. The stainless steel material of the baffle plate 52 is resistant to feed corrosion, and the rigid structure ensures the stability of the position after adjustment, avoids the volume deviation caused by feed compression, and ensures the smooth movement of the baffle plate.

[0039] The electric telescopic rod 51 is based on the screw drive principle. The motor drives the screw to rotate, converting the rotational motion into linear motion, which pushes the baffle plate 52 to slide along the feed trough. The baffle plate adjusts the volume of space in the feed trough that can hold feed by changing its position, thus achieving quantitative adjustment. The microprocessor controls the extension length of the telescopic rod to precisely set the feed output, thereby controlling the amount of feed given at one time. Based on the size of the farmed organisms, the microprocessor presets the feed output. Before feeding, the microprocessor controls the electric telescopic rod 51 to extend to the corresponding length, and the baffle plate 52 moves to the preset position. When feeding, the feed falls into the feed trough, filling the space defined by the baffle plate. The feeding seat 42 rotates to the discharge pipe position, and the feed is discharged. If the feeding amount needs to be adjusted, the microprocessor controls the telescopic rod to extend and retract, and the baffle plate to move, adjusting the feed output. The microprocessor has a built-in volume-stroke correspondence database and automatically calls the telescopic rod stroke according to the target feeding amount.

[0040] Preferably, of any of the above solutions, the protective end cap 6 is fixedly installed on the top of the feeding bin 3 by threads, and the bottom of the protective end cap 6 is provided with a detection groove for fixing the laser rangefinder sensor 8.

[0041] The above technical solution is adopted: the protective end cap 6 is connected to the top of the feeding bin 3 by threads, and a feeding port (with a threaded cap) is opened on the surface. The detection groove at the bottom is located on one side of the center of the end cap and is used to fix the laser rangefinder sensor 8. The groove wall is covered with a rubber buffer pad. The threaded connection ensures that the end cap and the feeding bin 3 are tightly sealed and can be quickly disassembled for easy replenishment of bait and internal maintenance of the feeding bin. The feeding port facilitates the addition of bait. The threaded cap prevents bait from splashing and rainwater from entering during feeding. The detection groove accurately fixes the laser rangefinder sensor 8 to ensure that the detection direction is perpendicular to the pressing plate 7. The rubber buffer pad can absorb sensor vibration and avoid fluctuations in detection data.

[0042] The threaded connection is based on the principle of a helical pair, achieving a tight fit through rotating the end cap. The threaded sealing surface blocks external water and impurities. The feeding port, through its circular opening and threaded cap, achieves the dual functions of bait replenishment and sealing. The detection groove, through its geometric dimensions and buffer pad, provides a stable installation reference for the sensor and reduces environmental interference. The overall structure of the end cap, made of rigid material, protects the bait inside the feeding chamber from external contamination. When replenishing bait, unscrew the threaded cap of the feeding port on the protective end cap 6, pour the bait into the feeding chamber 3 through the feeding port until the bait height reaches the preset position, and tighten the threaded cap to ensure a seal. When installing the laser rangefinder sensor 8, embed it into the detection groove, with the buffer pad fitting against the sensor housing and secured with bolts. During feeding, the end cap prevents rainwater and debris from entering the feeding chamber, and the sensor in the detection groove monitors the position of the pressing plate in real time. During maintenance, rotate the end cap counterclockwise, remove it, and clean the residual bait from the inner wall of the feeding chamber.

[0043] Preferably, the pressing plate 7 includes a suspended detection line 71 and a lightweight material plate 72 that moves up and down with the bait. The detection line 71 is fixedly installed at the bottom of the protective end cover 6, and the lightweight material plate 72 located below the protective end cover 6 is fixedly installed at the bottom of the detection line 71.

[0044] The above technical solution is adopted: one end of the detection line 71 (nylon line) of the pressing plate 7 is tied to the bottom hook of the protective end cap 6, and the other end is connected to the lightweight material plate 72. The lightweight material plate 72 (PP material) is horizontally suspended inside the feeding chamber 3, floating on the surface of the bait, and descends synchronously as the amount of bait decreases. The surface of the material plate is sprayed with a reflective coating to facilitate detection by the laser range sensor 8. The nylon material of the detection line 71 is resistant to bait corrosion, and the low elasticity coefficient ensures accurate detection of the material plate position. The lightweight material plate 72 is lightweight and can move flexibly with the rise and fall of the bait surface without compacting the bait. The reflective coating enhances the laser reflection signal, ensuring that the laser range sensor 8 can still detect accurately in dim environments. The horizontal structure of the material plate ensures that the detection position represents the average height of the bait and avoids misjudgment of the remaining amount caused by local protrusions.

[0045] The pressing plate 7 is based on the principle of balance between gravity and buoyancy. The lightweight plate 72 is much lighter than the supporting force of the bait, and can rise and fall synchronously with changes in the amount of bait. The detection line 71, through a suspension structure, limits the movement of the plate to only the vertical direction, ensuring a stable detection position. The reflective coating enhances the laser signal intensity and improves the sensor's detection accuracy through the principle of optical reflection. The adhesion between the plate and the bait surface converts the remaining bait weight into the vertical displacement of the plate, facilitating quantitative detection by the sensor. When the feeding bin 3 is full of bait, the lightweight plate 72 is supported by the bait and is located at a high position, where the laser rangefinder 8 detects the plate. The microprocessor records the initial balance. After feeding begins, the bait gradually decreases, and the bait pieces descend synchronously with the bait surface. The sensor detects the distance change in real time. The microprocessor calculates the bait consumption based on the distance change and the cross-sectional area of ​​the feeding chamber. When the balance is insufficient, an alarm is triggered. The microprocessor calculates the remaining bait in real time using the distance data from the laser rangefinder 8 and the volume parameters of the feeding chamber. A balance threshold is set. When the balance is ≤10%, the alarm light 9 flashes yellow; when it is ≤5%, the red light remains on. The position of the bait pieces is calibrated periodically, and the tension of the detection line 71 is checked to prevent the bait pieces from tilting.

[0046] Preferably, of any of the above schemes, the alarm light 9 is fixedly installed on the top of the protective end cover 6, and the laser range sensor 8 is located on one side of the detection line 71 and above the lightweight material sheet 72.

[0047] The above technical solution is adopted: the alarm light 9 (LED three-color alarm light, connected to the microprocessor signal) is fixed to the top of the protective end cover 6 by a bracket, and can emit three colors of light: red, yellow and green (red light: insufficient bait, yellow light: low balance reminder, green light: normal). The laser range sensor 8 (infrared type, connected to the microprocessor signal) is fixed to the detection slot at the bottom of the protective end cover 6, with the detection end pointing vertically downward, located on one side of the detection line 71 and directly above the lightweight material piece 72. The three-color light of the alarm light 9 can intuitively reflect the status of the device, which is convenient for operators to observe from a distance. The LED light source has a long life and low power consumption and is compatible with the device's battery power supply. The high-precision detection of the laser range sensor 8 can accurately capture the slight displacement of the lightweight material piece 72 and provide real-time feedback on the remaining bait. The sensor position design can avoid the detection line from blocking the laser and ensure the stability of the detection signal.

[0048] Alarm light 9 is based on the LED light-emitting principle. The microprocessor controls different colored LEDs to light up via switch signals to indicate status. Laser rangefinder 8, based on the time-of-flight principle, emits infrared light to the reflective coating of lightweight material sheet 72, receives the reflected light, calculates the distance, converts the distance signal into an analog signal, and transmits it to the microprocessor. The microprocessor determines the remaining bait based on the distance data and controls the corresponding colored alarm light to light up. After the device is started, laser rangefinder 8 begins to work, transmitting material sheet distance data to the microprocessor every 100ms. When there is sufficient bait, the microprocessor controls alarm light 9 to remain constantly green. As feeding continues... As the feed pellets descend, the distance increases. When the distance reaches 10% of the remaining amount, the alarm light switches to a flashing yellow light. Continue feeding until the remaining amount reaches 5%, at which point the alarm light switches to a solid red light. After adding more feed, the feed pellets rise, the distance decreases, and when the remaining amount exceeds 10%, the alarm light returns to green. If the sensor detects abnormal distance data, the alarm light flashes red and yellow alternately to indicate a fault. The microprocessor presets a distance threshold; when the distance exceeds the threshold, the alarm light color changes. A digital filtering algorithm is used to process sensor data, removing fluctuation noise. The sensor is calibrated regularly to adjust detection errors and ensure accuracy. The alarm light cover is cleaned regularly to remove dust and maintain visibility.

[0049] The working principle of the partitioned quantitative feeding device of the present invention is as follows:

[0050] First, the feeding float 1 is placed on the water surface of the aquaculture area. The inert gas inside ensures the device floats stably. The partition positioning rope at the bottom of the feeding bracket 2 is tied to the positioning stake on the shore to limit the feeding range. After the microprocessor is started, it controls the propulsion paddle motor to run, driving the device to move along the positioning rope path to the predetermined partition at a preset speed. Then, the microprocessor controls the discharge motor 41 of the discharge hopper 4 to start and controls the electric telescopic rod 51 of the feeding partition 5 to extend and retract, adjusting the position of the baffle plate 52, causing the feeding seat 42 to rotate in the rotating groove at the bottom of the feeding bin 3. The feed in the feeding bin 3 falls into the feeding trough. When the feeding trough rotates with the feeding seat to the position of the discharge pipe, the feed flows along the inclined discharge pipe. The feed is directed to the aquaculture area. A waterproof sealing strip adheres to the inner wall of the rotating trough to prevent water from entering. The laser range sensor 8 at the bottom of the protective end cap 6 monitors the position of the lightweight feed piece 72 on the pressing plate 7 in real time. The feed piece descends synchronously as the feed decreases. The sensor transmits the distance data to the microprocessor to calculate the remaining feed. If the remaining feed is >10%, the alarm light 9 on the top of the protective end cap remains green. If the remaining feed is ≤10%, the yellow light flashes to remind the user to replenish the feed. If the remaining feed is ≤5%, the red light remains on. After feeding is completed, the microprocessor controls the discharge motor and the propulsion paddle motor to stop, and the device returns to its initial position. All structures work together to achieve zoned and quantitative feeding in the aquaculture area, improving feed utilization and feeding uniformity.

[0051] Compared with the prior art, the present invention has the following advantages:

[0052] 1. A feeding hopper 4 is installed at the bottom of the feeding bin 3, which rotates around it. By controlling the position of the feeding baffle 5 inside the feeding hopper 4, feed can be fed into the fishpond. During the feeding process, the feeding hopper 4 is rotated so that the feeding float 1 can be used as the center for circumferential feeding, which increases the range and area of ​​feeding and makes it easier to distribute feed in a certain area. At the same time, the laser range sensor 8 installed at the top of the protective end cover 6 detects the position change data of the pressing plate 7. Combined with the inherent size of the feeding bin 3, the amount of feed can be determined, which improves the accuracy of feeding and the convenience of feeding.

[0053] 2. The pressing plate 7 is set to rise and fall with the amount of bait. The laser range sensor 8 can detect the pressing plate 7 in real time to judge the amount of bait used and the remaining amount. The alarm light 9 is controlled to sound an alarm based on the remaining amount, so as to detect the lack of bait in time and replenish it, which is conducive to continuous and stable feeding.
