Description

TECHNICAL FIELD

[0001] The present application relates to the field of fish and shrimp breeding, in particular to a feeding machine for lotus pond fish and shrimp breeding. BACKGROUND

[0002] In the production of lotus pond fish and shrimp breeding, the feeding machine as the core equipment to ensure uniform feeding of fish and shrimp and improve breeding efficiency, with its advantages of reducing labor intensity of manual feeding and realizing timed and quantitative feeding, has been widely used in large-scale lotus pond mixed breeding scene. At present, through the feeding machine, the feed is accurately put into the lotus pond, which can not only avoid the waste caused by the feed spilling on the bank during manual feeding, but also make the fish and shrimp feed more evenly by controlling the feeding rhythm, reduce the pollution of residual feed to the water body, and further improve the breeding income by cooperating with the ecological complementary characteristics of lotus pond.

[0003] In the prior art, for example, the small Qingqing STLZ-120W type vibration type fish pond feeding machine, the device is fixed on one side of the lotus pond bank through a support, carries a vibration type feed bin with a built-in vibration motor and a centrifugal feed throwing disc driven by a main motor. The vibration motor can reduce the clogging of the feed, and the main motor drives the feed throwing disc to rotate and throw the feed. The device is provided with rubber walking wheels at the bottom, which needs to be manually pushed along the single-layer slide rail of the pond bank, and cooperates with the mechanical timer to realize the timed feeding in the area of the pond bank. Compared with the traditional manual feeding bucket, the basic labor can be reduced, and it is widely used in small and medium-sized ponds.

[0004] However, in the actual use of the above feeding machine, the breeding personnel usually need to manually push the rack along the single-layer slide rail of the pond bank every hour, and because the device is only fixed on one side and has no cross-pool moving structure, it can only cover an area of 3-4 meters on the bank. This way of relying on manual pushing and covering on one side cannot cover the central area of the lotus pond, and the labor cost is high and the efficiency is low. Moreover, the device cannot automatically supplement the feed in time when feeding. Therefore, it is necessary to provide a feeding machine for lotus pond fish and shrimp breeding. SUMMARY

[0005] To solve the above problems, the present application provides a feeding machine for lotus pond fish and shrimp breeding, which is used in the lotus pond fish and shrimp breeding scene, and feeds through the transmission rope driven by the motor and installed across the pond, and cooperates with the feeding hopper to solve the problems of the existing feeding machine that only covers the bank, the complicated operation of supplementing the feed, and the untimely supplement of the feed, realizes uniform feeding of the feed in the lotus pond, and automatically and continuously supplements the feed during the feeding process.

[0017] Further, the feeding opening is detachably connected with a cover.

[0036] The following will be further described in detail through specific embodiments: EMBODIMENT

[0037] As shown in the drawingsFigure 1 and Figure 2 As shown in the figure: a lotus root pool fish and shrimp breeding feeding machine, including double head drive 1, controller, fixed column 17 and feeding box 8.

[0038] The controller is used to control the opening and closing of the double head drive 1. One end of the double head drive 1 is bolted to the output end of the rotating rod 2. The other end of the rotating rod 2 is rotatably connected to the transmission rod 3. The other end of the transmission rod 3 is rotatably connected to the fixed rod 6. The other end of the fixed rod 6 is welded to the baffle 7. The baffle 7 is slidably connected to the inner wall of the feeding box 8.

[0039] The other output end of the double head drive 1 is bolted to the first rotating disc 12. The first rotating disc 12 is rotatably connected to the transmission rope 13. The end of the transmission rope 13 away from the first rotating disc 12 is rotatably connected to the second rotating disc 14. The second rotating disc 14 is rotatably connected to the fixed column 17. The side wall of the feeding box 8 is provided with a guide assembly for stable movement of the fixed rod 6.

[0040] The guide assembly includes a sliding rail 5 and a sliding block 4. One end of the sliding rail 5 is welded to the side wall of the feeding box 8. One end of the sliding block 4 is slidably connected to the sliding rail 5. The other end of the sliding block 4 is bolted to the end of the transmission rod 3 close to the fixed rod 6.

[0041] Specifically, the fixed column 17 is erected on one side of the lotus root pool. The double head drive 1 and the feeding box 8 are erected on the other side of the lotus root pool. The controller starts the double head drive 1. One output end of the double head drive 1 drives the rotating rod 2 to make circular motion. Since the other end of the rotating rod 2 is rotatably connected to the transmission rod 3, the end of the transmission rod 3 follows the rotating rod 2 to swing. The other end drives the fixed rod 6 and the baffle 7 rotatably connected thereto to make reciprocating linear motion in the feeding box 8. The sliding block 4 follows the transmission rod 3 to make reciprocating linear motion on the sliding rail 5. The double head drive 1 in this embodiment is a double head DC motor.

[0042] As shown in the figure: Figure 3 and Figure 4 The top of the feeding box 8 is provided with a discharging assembly for feeding. The discharging assembly includes a storage box 10 and a stirring member 9. The bottom of the stirring member 9 is fixedly connected to the top of the feeding box 8. The top of the stirring member 9 is fixedly connected to the bottom of the storage box 10. The communication between the storage box 10 and the stirring member 9 is fixedly connected to an electromagnetic valve. The electromagnetic valve is electrically connected to the controller. The top of the storage box 10 is provided with a feeding opening. The inner wall of the storage box 10 is bolted to a partition plate 22. The feeding opening is detachably connected to a cover.

[0043] Specifically, the breeding personnel can pre-feed fish feed and shrimp feed into the independent space separated by the partition plate 22 in the storage box 10 through the feeding opening, and then close the feeding opening with the cover. When it is necessary to supplement the feed in the feeding box 8, the controller controls the electromagnetic valve to open, releasing the feed in the storage box 10, which is guided by the baffle 7 to the feeding box 8. Figure 4It can be known that the stirring piece 9 of the embodiment is spiral, and the two kinds of feeds are mixed after passing through the spiral stirring piece 9 due to gravity, and then fall into the feeding box 8.

[0044] The fixed plate 20 is fixedly connected to the transmission rope 13, and the fixed plate 20 is integrally formed with a feeding hopper 11 on the side wall. The outer side wall of the feeding box 8 is provided with a limiting assembly for guiding and limiting the movement of the fixed plate 20, and the limiting assembly comprises a first fixed block 15 and a second fixed block 16. The first fixed block 15 and the second fixed block 16 are both welded to the outer side wall of the feeding box 8. The side walls of the first fixed block 15 and the second fixed block 16 are respectively fixedly connected with a first sliding rod 18 and a second sliding rod 19 through bolts. The other ends of the first sliding rod 18 and the second sliding rod 19 are both fixedly connected with a fixed column 17 through bolts. The second rotating disc 14 is in rotating cooperation with the fixed column 17.

[0045] A plurality of guide wheels 21 are in rotating cooperation with the top and bottom of the fixed plate 20. The guide wheels 21 on the top of the fixed plate 20 are in sliding cooperation with the first sliding rod 18. The guide wheels 21 on the bottom of the fixed plate 20 are in sliding cooperation with the second sliding rod 19. The top of the feeding hopper 11 is in communication with the discharge port. In the embodiment, the feeding hopper 11 is in communication with the discharge port through a hose.

[0046] Specifically, as shown in Figure 1 and Figure 2 and Figure 3 The first sliding rod 18 and the second sliding rod 19 and the transmission rope 13 span the lotus root pond. When the first rotating disc 12 drives the second rotating disc 14 and the transmission rope 13 to rotate, the fixed plate 20 moves with the transmission rope 13. The first sliding rod 18 and the second sliding rod 19 and the guide wheels 21 limit and guide the fixed plate 20, so that the fixed plate 20 moves stably and linearly. The fixed plate 20 drives the feeding hopper 11 to move. Since the baffle 7 reciprocates linearly in the feeding box 8, the feed falling into the feeding box 8 can be pushed out of the discharge port. The feed is transported to the feeding hopper 11 through the discharge port and the hose, so as to feed the fish and shrimps in the lotus root pond. Since the types of feed are different, the feed will self-layer after entering the water. The feed is automatically and continuously replenished when the feeding hopper 11 moves, which simplifies the feeding process and makes the feeding more uniform, avoiding the interruption of feeding due to insufficient feeding.

[0047] The present application drives the feeding hopper 11 to span the lotus root pond and drives the baffle 7 to reciprocate linearly through the double-head driving piece 1 to drive the transmission rope 13 and the fixed plate 20, so as to realize the pushing of the feed in the feeding box 8. A single power source realizes the dual functions of feeding and replenishing, which simplifies the overall structure of the equipment, reduces the probability of mechanical failure, reduces energy consumption, and improves the economy and stability of the equipment operation.

[0048] This invention utilizes a cross-pond structure consisting of a first slide bar 18, a second slide bar 19, and a transmission rope 13, combined with the moving feeding hopper 11, to achieve full coverage of a conventional lotus pond. This reduces the feeding blind spots that existing feeders only cover at the pond edges, lowers the average weight difference between fish and shrimp at the pond edges and in the center, and significantly improves feeding uniformity. Furthermore, the feeding hopper 11 delivers feed vertically downwards, avoiding the problem of lotus stems and leaves blocking feed when thrown horizontally, increasing the probability that feed will effectively reach the target area at the bottom of the pond and reducing feed waste. Example

[0049] As attached Figure 1 and Figure 4 As shown, the difference from Embodiment 1 is that the inner wall of the storage box 10 and the inner surface of the agitator 9 are coated with a smooth coating, and a scraper strip is attached to the side of the baffle 7. The side of the scraper strip away from the baffle 7 is slidably connected to the inner wall of the feeding box 8.

[0050] Specifically, when feeding feed from storage bin 10 to feeding bin 8, the smooth coating reduces the friction between the feed and the inner wall of storage bin 10 and the inner surface of the agitator 9, helping the feed fall more smoothly and pass through the agitator 9. As the scraper moves with the baffle 7, it adheres to the inner wall of feeding bin 8, further pushing the feed in feeding bin 8 out and reducing residue. Example

[0051] As attached Figure 3 As shown, the difference from Embodiment 2 is that an infrared sensor is glued and fixed to the inner side wall of the storage box 10. The infrared sensor is used to detect the feed balance signal in the storage box 10 and transmit the feed balance signal to the controller. The controller sends an alarm to the mobile terminal of the farmer based on the feed balance signal sent by the infrared sensor.

[0052] It also includes a water temperature sensor, a dissolved oxygen sensor, and a timer. The water temperature sensor and dissolved oxygen sensor are bolted to the wall of the lotus pond, and the timer is bolted to the outer wall of the feeding box 8. The water temperature sensor is used to detect the water temperature in the lotus pond and transmit the temperature signal to the controller. The dissolved oxygen sensor is used to detect the dissolved oxygen level in the lotus pond and transmit the dissolved oxygen signal to the controller. The timer is used to record the time interval since the last feeding and the duration of feed release, and transmits the time interval signal and the duration of feed release signal to the controller. The controller performs operations according to the following logic based on the temperature signal, dissolved oxygen signal, time interval signal, duration of feed release signal, and remaining feed signal: When the time interval signal is ≥4 hours, the temperature signal is in the range of 18-28℃, and the dissolved oxygen signal is ≥5mg / L, the solenoid valve will be opened to release feed.

[0053] If the feed remaining value of the feed remaining signal is > 30%, the feed release duration is set to 100% of the rated duration.

[0054] If the feed remaining value is 10%-30%, the feed release duration is set to 90% of the rated duration.

[0055] If the feed remaining value is < 10%, the feed release duration is set to 50% of the rated duration.

[0056] The controller closes the solenoid valve when the time value of the feed release duration signal reaches the set value based on the feed release duration signal.

[0057] If the time value of the time interval signal is < 4 hours, the feed release is not triggered.

[0058] If the time value of the time interval signal is ≥ 8 hours, the feed release is directly triggered.

[0059] Specifically, the controller is pre-set with a minimum feed remaining threshold value, and when the infrared sensor detects that the feed remaining in the feed tank 10 is lower than the threshold value, the controller sends an alarm to the mobile terminal of the breeder and reminds the breeder to replenish the feed.

[0060] When the device is started for the first time, a feeding process will be performed, the double-head drive 1 is forward rotated, the solenoid valve is opened, and the feeding hopper 11 is moved from one end of the pond to the other end of the pond, then the double-head drive 1 is reversed, and the feeding hopper 11 returns to the original position. During this process, the timer starts timing from when the solenoid valve is opened, and then the controller controls the opening and closing of the solenoid valve based on the feed remaining signal and the feed release duration signal, and this process completes a feeding.

[0061] After that, the water temperature sensor and the dissolved oxygen sensor will capture the environmental indicators, and the timer will record the time point of each feeding of the feed and calculate the time interval from the last feeding.

[0062] Specifically, the water temperature sensor detects the water temperature in real time and transmits it to the controller, and when the detected water temperature is in the range of 18-28℃, a temperature suitable signal is generated; the dissolved oxygen sensor synchronously detects the dissolved oxygen concentration of the water body, and if the dissolved oxygen concentration is ≥ 5 mg / L, a dissolved oxygen sufficient signal is generated.

[0063] When the controller receives the temperature suitable signal and the dissolved oxygen sufficient signal, and the controller determines that the time interval from the last feeding is ≥ 4 hours based on the timer, a feeding process is triggered, and after the process is completed, the timer records the feeding time, and the controller restarts the calculation of the time interval from the last feeding. If the temperature suitable signal and the dissolved oxygen sufficient signal are not received, or the controller determines that the time from the last feeding is < 4 hours, the feeding process is not triggered, and when the time from the last feeding is ≥ 8 hours, a longest interval bottom feeding is triggered, and a feeding process is performed.

[0064] Obviously, the above embodiments are merely example for clearly illustrating but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments need not and can not be enumerated. The obvious changes or variations derived from the above description are still within the protection scope of the present application.

The lotus root fish and shrimp breeding feeding machine according to claim 7, characterized in that, The inner side wall of the storage tank (10) is fixedly connected with an infrared sensor, the infrared sensor is used for detecting a feed remaining amount signal in the storage tank (10) and transmitting the feed remaining amount signal to the controller, and the controller sends an alarm to a breeding personnel mobile terminal based on the feed remaining amount signal.

9. The lotus root fish and shrimp breeding feeding machine according to claim 8, characterized in that, The guide assembly comprises a slide rail (5) and a slide block (4), one end of the slide rail (5) is fixedly connected with the side wall of the feeding box (8), one end of the slide block (4) is in sliding fit with the slide rail (5), and the other end of the slide block (4) is fixedly connected with one end of the transmission rod (3) close to the fixed rod (6).

10. The lotus root fish and shrimp breeding feeding machine according to claim 9, characterized in that, The water temperature sensor and the dissolved oxygen sensor are both fixedly connected to the pool wall of the lotus root pool, and the timer is fixedly connected to the outer side wall of the feeding box (8). The water temperature sensor is used for detecting the water temperature in the lotus root pool and transmitting a temperature signal to the controller. The dissolved oxygen sensor is used for detecting the dissolved oxygen content in the lotus root pool and transmitting a dissolved oxygen signal to the controller. The timer is used for recording the time interval from the last feeding and the length of time for releasing feed, and transmitting a time interval signal and a length of time signal to the controller. The controller performs operations according to the following logic based on the temperature signal, the dissolved oxygen signal, the time interval signal, the length of time signal and the feed remaining signal: When the time value of the time interval signal is greater than or equal to 4 hours, the temperature value of the temperature signal is in the range of 18-28℃, and the dissolved oxygen concentration value of the dissolved oxygen signal is greater than or equal to 5mg / L, the electromagnetic valve is opened to release feed; If the feed remaining value of the feed remaining signal is greater than 30%, the length of time for releasing feed is set to 100% of the rated length of time, if the feed remaining value is 10%-30%, the length of time for releasing feed is set to 90% of the rated length of time; If the feed remaining value is less than 10%, the length of time for releasing feed is set to 50% of the rated length of time, and the controller closes the electromagnetic valve based on the length of time signal for releasing feed when the time value of the length of time signal reaches the set value; When the time value of the time interval signal is less than 4 hours, the feed release is not triggered; when the time value of the time interval signal is greater than or equal to 8 hours, the feed release is directly triggered.
