[0001] This utility model relates to the field of automatic feeding device technology, specifically to a small automatic feeding device for aquaculture. Background Technology
[0002] Chinese patent CN216601293U discloses an automatic feeding device for mixed feed in aquaculture. The device includes an automatic feeding unit, a stirring unit, a feeding unit, and a base. The feeding unit is mounted on the top of the base, and the stirring unit is also mounted on the top. The stirring unit includes a stirring tank, a motor, a rotating shaft, a stirring rod, and a feeding hole. The motor is mounted on the top of the stirring tank, and the rotating shaft is mounted on the bottom. The stirring rod is mounted on the outer wall of the rotating shaft. The feeding unit includes a storage box, a rotating plate, a slide rail, a telescopic cylinder, a spring, and a guide plate. The top of the storage box is mounted on the bottom of the stirring tank, and the bottom is mounted on the top of the base. This automatic feeding device for mixed feed in aquaculture, through the gravity of the feed combined with the rotating plate, telescopic cylinder, slide rail, and spring, enables automatic feeding, eliminating the need for manual, timed, and quantitative feeding, thus saving manpower.
[0003] However, the following shortcomings still exist:
[0004] Several problems exist in the operation of small-scale automatic feeding devices for aquaculture: First, it is impossible to classify and store feeds required by different fish species, making it difficult to meet differentiated feeding needs. Second, feed supply is prone to interruption, causing the entire feeding process to stagnate and fish to fail to feed on time. Third, the timing and amount of feed delivery lack precise control, which may result in uncontrolled continuous feed leakage and overfeeding. This not only wastes feed and increases aquaculture costs but also pollutes the aquaculture water quality, increases management difficulty, and may also cause the optimal feeding time to be missed, affecting fish growth. Fourth, it is difficult to achieve fixed-point feeding and cannot accurately deliver feed to the target area, further reducing the effectiveness of feeding. Therefore, those skilled in the art provide a small-scale automatic feeding device for aquaculture to solve the problems mentioned in the background art. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a small automatic feeding device for aquaculture, including a shell assembly 1 for support and stability, a storage assembly 2 for storing feed inside the shell assembly 1, a discharge hopper 208 inside the storage assembly 2, a length adjustment assembly 3 for controlling the length of the discharge hopper 208 inside the storage assembly 2, and a discharge control assembly 4 for covering the discharge hopper 208 at the lower end of the storage assembly 2.
[0022] As one implementation method in this embodiment, please refer to Figures 2-4As shown, the housing assembly 1 includes a housing 101, with brackets 102 fixedly installed on both sides of the housing 101. A control panel 103 is fixedly installed on the upper end of the brackets 102. Three sets of channel feeding indicator lights 104 are provided on the front of the housing 101. The storage assembly 2 includes a feeding hopper 201, which is fixedly installed on one side of the upper end of the housing 101. There are three sets of feeding hoppers 201. Conical storage bins 202 are fixedly installed at the lower end of each of the three sets of feeding hoppers 201 near the interior of the housing 101. Conical storage bins 202 are fixedly installed at the upper end of each of the three sets of conical storage bins 202 near the middle of the top surface of the housing 101. An alarm 2003 is installed. Each of the three sets of conical storage hoppers 202 has a zoned timer controller 203 at the front center. Each of the three sets of conical storage hoppers 202 has a guide hopper 204 fixedly connected to its lower end. Each of the three sets of guide hoppers 204 has a guide pipe 205 fixedly connected to its lower end. Each of the three guide pipes 205 has a plastic telescopic flexible hose structure. Each of the three guide hoppers 204 has a gravity sensor 206 installed inside its lower end. Each of the three guide pipes 205 has a discharge pipe 207 fixedly connected to its lower end near the lower end of the housing 101. Each of the three discharge pipes 207 has a discharge hopper 208 fixedly connected to its lower end.
[0023] Furthermore, the device utilizes three sets of feeding hoppers 201 to separately transport feed for different fish species to corresponding conical storage bins 202 for temporary storage. The three sets of conical storage bins 202 within the housing 101 enable the categorized storage of feed for different fish species. Using a zoned timer controller 203, feeding times can be set according to the needs of each fishpond. A gravity sensor 206 within the feed guide hopper 204 monitors the remaining feed level in real time. When feed is insufficient, the gravity sensor 206 transmits a detection signal to the control terminal, at which point the alarm 2003 issues a warning. During the feeding process, the feed... The feed will pass through the feed hopper 204, the guide pipe 205 whose placement position can be flexibly adjusted, and the discharge pipe 207 in sequence, and finally be accurately delivered to the corresponding fish pond or a designated area within the fish pond by the discharge hopper 208. At the same time, the feeding indicator lights 104 of each channel will display the feeding status of each channel, thereby realizing automatic feeding of multiple fish ponds, differentiated feeding, and timed and fixed-point feeding. This meets the needs of simultaneously serving multiple fish breeding ponds, storing different fish feeds, flexibly and accurately setting feeding time and location according to the breeding needs of different fish ponds, as well as differentiated feeding of different species of fish and feeding on demand in different areas of the same fish pond.
[0024] As one implementation method in this embodiment, please refer to Figure 4 As shown, the length adjustment component 3 includes a fixed rod 301, which is symmetrically fixed on both sides of the guide hopper 204. A cylinder 302 is provided at the lower end of the fixed rod 301. A collar 303 is movably installed near the outside of the guide pipe 205 at the telescopic end of the cylinder 302. A traction rod 304 is fixedly connected in a ring array inside the collar 303. The collar 303 is connected to the guide pipe 205 through the traction rod 304.
[0025] Furthermore, when the position of the discharge hopper 208 needs to be adjusted, the cylinder 302 fixed at the lower end of the fixing rods 301 on both sides of the guide hopper 204 is activated, and its telescopic end drives the collar 303 to move up and down. Since the collar 303 is connected to the guide pipe 205 through the traction rods 304 distributed in a ring array, the movement of the collar 303 will pull the guide pipe 205 through the traction rods 304, causing the guide pipe 205 to lengthen or shorten, thereby changing the length and delivery position of the discharge hopper 208, accurately adapting to the feeding needs of different fish ponds or different areas within the same fish pond, and improving the flexibility and accuracy of feed delivery.
[0026] As one implementation method in this embodiment, please refer to Figure 4 As shown, the discharge control component 4 includes a fixed base 401, which is fixedly installed in front of the discharge hopper 208. The fixed base 401 is L-shaped. A cylinder 402 is provided at the upper end of the horizontal end of the fixed base 401. A cover plate 403 is movably installed at the telescopic end of the cylinder 402 near the lower end of the discharge hopper 208.
[0027] Furthermore, when feeding, cylinder 402 on the horizontal end of the L-shaped fixed seat 401 at the front of the hopper 208 is activated, and the telescopic end drives the cover plate 403 to move, opening the discharge port of the hopper 208 so that the feed can be fed. When feeding is not needed, cylinder 402 resets the cover plate 403 to close the discharge port, preventing feed leakage. The discharge control component 4 controls the opening and closing of the hopper 208 precisely to control the timing and amount of feed feeding, ensuring that the feed is accurately fed to the designated area at the set time, avoiding premature leakage or overfeeding, and improving the accuracy and controllability of feeding.
[0028] Working principle: The device uses three sets of feeding hoppers 201 to feed different feeds into corresponding conical storage bins 202 for temporary storage. The zone timer controller 203 sets the feeding time according to the needs of the fish pond. The gravity sensor 206 in the feed guide hopper 204 monitors the remaining feed. When the feed is insufficient, the alarm 2003 issues a warning. During feeding, the feed passes through the feed guide hopper 204, the adjustable guide pipe 205, and the discharge pipe 207, and is accurately delivered to the corresponding fish pond or area by the discharge hopper 208. The feeding indicator lights 104 of each channel show the status, realizing automatic feeding of multiple fish ponds at different times and locations, meeting the needs of multiple scenarios.
[0029] When adjusting the position of the discharge hopper 208, the cylinder 302 under the fixed rods 301 on both sides of the guide hopper 204 is activated, and the telescopic end drives the collar 303 to move up and down. The collar 303 pulls the guide tube 205 to extend and retract through the traction rods 304 of the ring array, changing the length and placement position of the discharge hopper 208 to adapt to different feeding needs and improve the accuracy and flexibility of the placement.
[0030] When feeding, cylinder 2 402 moves cover plate 403 away, opening the discharge port of discharge hopper 208 to release feed. When not feeding, cylinder 2 402 resets cover plate 403 to close, preventing feed leakage. Discharge control component 4 precisely controls the opening and closing of discharge hopper 208, controlling the timing and amount of feeding, ensuring timely and accurate feed delivery, avoiding leakage or overfeeding, and improving feeding accuracy and controllability.
[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
