[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4 An automatic feeding device for zebrafish farming is shown, including a chassis 1, a fixed cover 2 fixedly connected to the top of the chassis 1, and a movable cover 3 movably connected to the inner side wall of the fixed cover 2.

[0025] Both the fixed cover 2 and the movable cover 3 have guide ports 4 symmetrically arranged around their four sides;

[0026] A protective shell 5 is installed at the bottom of the chassis 1. The inner cavity of the protective shell 5 is provided with a rotating mechanism 6 that works in conjunction with the movable cover 3. One end of the rotating mechanism 6 passes through the chassis 1 and is fixedly connected to the top of the inner cavity of the movable cover 3.

[0027] The bottom of the protective shell 5 is equipped with a support assembly 7 for fixing it to the fish tank;

[0028] The chassis 1 serves as the base to support the fixed cover 2. The movable cover 3 is movably connected to the inner wall of the fixed cover 2. The rotating mechanism 6 is installed inside the protective shell 5 and one end is connected to the movable cover 3. It can drive the movable cover 3 to rotate relative to the fixed cover 2, so that the feed inlets 4 around the two are aligned (feeding) or staggered (feeding is stopped). The support component 7 fixes the automatic feeding device on the fish tank to achieve overall installation and positioning.

[0029] The relative rotation of the fixed cover 2 and the movable cover 3 controls the state of the feed inlet 4, and the rotating mechanism 6 enables automated control of feed feeding, solving the problem of low efficiency of manual feeding. The support component 7 ensures that the device is stably installed on the fish tank, providing a reliable foundation for automatic feeding and adapting to the needs of aquaculture scenarios.

[0030] The chassis 1 is sloped around its perimeter, and a feeding trough 8 is provided at the edge of the chassis 1 corresponding to the feed inlet 4.

[0031] The sloping surfaces around the chassis 1 guide the feed falling from the feed inlet 4 to slide towards the edge, and the feeding trough 8, which corresponds to the feed inlet 4, receives the feed and guides it to the breeding area inside the aquarium.

[0032] The sloping surface prevents feed from piling up in the center of the chassis 1, and the feeding trough 8 precisely guides the feed into the breeding area, reducing feed residue and waste, ensuring that zebrafish can feed smoothly and improving feed utilization.

[0033] The inner cavity of the fixed cover 2 is provided with a conical platform 9, and the bottom of the conical platform 9 is fixed at the center of the top of the chassis 1;

[0034] The conical platform 9 inside the fixed cover 2 is fixed to the center of the chassis 1. After the feed is put into the conical platform 9, it slides along the inclined surface of the conical platform 9 to the surrounding area, making it easy to enter the feed inlet 4 of the fixed cover 2 and the movable cover 3.

[0035] The conical platform 9 can prevent feed from piling up in the center of the fixed cover 2, guide the feed to the surrounding feed inlets 4, ensure that the feed is smoothly fed through the feed inlets 4, reduce feed blockage, and improve feeding smoothness.

[0036] The rotating mechanism 6 includes a motor body 61, which is installed inside the protective shell 5. A small gear 62 is fixedly connected to the output end of the motor body 61. A large gear 63 meshes with the surface of the small gear 62. A rotating shaft 64 is fixedly connected to the center of the large gear 63. The lower end of the rotating shaft 64 is rotatably connected to the bottom of the inner cavity of the protective shell 5. The upper end of the rotating shaft 64 passes through the chassis 1 and the conical platform 9 through a bearing and extends upward to be fixedly connected to the top of the inner cavity of the movable cover 3.

[0037] In the rotating mechanism 6, the motor body 61 drives the small gear 62 to rotate, the small gear 62 meshes with and drives the large gear 63 to rotate, and the large gear 63 transmits power through the rotating shaft 64, so that the moving cover 3 rotates synchronously with the rotating shaft 64, thereby controlling the alignment or misalignment of the fixed cover 2 and the guide port 4 of the moving cover 3.

[0038] The gear transmission structure ensures the smoothness and precision of the rotation of the moving cover 3, while the motor body 61 provides stable power to realize automated control. It is convenient to adjust the rotation angle and speed of the moving cover 3, accurately control the feed feeding amount and time, and improve the feeding accuracy and automation level.

[0039] The main body of the motor 61 can be a 28BYJ48 stepper motor. This model of motor is small in size, low in power consumption, and moderate in torque. It can accurately control the rotation angle through pulse signals, making it very suitable for such small load and high precision rotation scenarios. It can meet the precise control requirements of the moving cover 3 to the guide port 4 in the aligned or staggered state.

[0040] The rotation angle, speed and start / stop time of the motor body 61 are set by writing a control program, thereby enabling the rotation angle of the moving cover 3 to be controlled.

[0041] The outer wall of the fixed cover 2 is fixedly connected with a stop block 10 at a symmetrical position, and the outer wall of the movable cover 3 is fixedly connected with a limit block 11. The movable cover 3 moves between the two stop blocks 10 through the cooperation of the limit block 11.

[0042] When the movable cover 3 rotates, the limiting block 11 on its outer wall moves between the two stops 10 on the outer wall of the fixed cover 2. When the limiting block 11 contacts the stops 10, the movable cover 3 stops rotating, thereby limiting the maximum rotation range of the movable cover 3.

[0043] The cooperation between the stop block 10 and the limit block 11 prevents the moving cover 3 from rotating excessively, which could cause the feed inlet 4 to become misaligned. This ensures the stability of the alignment or misalignment of the feed inlet 4, avoids uncontrolled feed feeding, and improves the reliability of the device operation.

[0044] A limiting sleeve 12 is fixedly connected to the center of the bottom of the protective shell 5, and one end of the support component 7 is inserted into the inner cavity of the limiting sleeve 12;

[0045] The limiting sleeve 12 at the bottom of the protective shell 5 provides an installation interface for the support component 7. One end of the support component 7 is inserted into the limiting sleeve 12. The installation height of the device can be changed by adjusting the insertion depth. The plug-in connection facilitates the installation and disassembly of the support component 7.

[0046] The support assembly 7 includes a support rod 71, one end of which is inserted into the limiting sleeve 12, and the other end of the support rod 71 is fixedly connected to a card seat 72. A fastener 73 is provided on the side of the card seat 72 away from the support rod 71.

[0047] In the support assembly 7, the support rod 71 is connected to the protective shell 5 through the limiting sleeve 12, the card seat 72 fits against the edge of the fish tank, and the fastener 73, through the cooperation of the threaded sleeve and the lead screw, causes the lead screw to rotate and move in the threaded sleeve, thereby driving the positioning block at one end of the lead screw to move towards the fish tank, thus fastening the card seat 72 to the fish tank, thereby stabilizing the entire device in the designated position of the fish tank.

[0048] Fastener 73 can adapt to aquarium edges of different thicknesses, ensuring the device is securely installed, preventing the device from shaking or shifting during feeding, ensuring the accuracy of feed placement, and improving the stability and safety of the device.

[0049] In practical use, first fix the automatic feeding device on the fish tank through the support component 7, insert one end of the support rod 71 into the limiting sleeve 12 at the bottom of the protective shell 5, then let the card seat 72 fit against the edge of the fish tank, and fasten the card seat 72 through the fastener 73 (using the threaded sleeve and the screw to rotate the screw to move the positioning block towards the fish tank) to ensure stable installation of the device.

[0050] Before use, feed is added to the fixed cover 2. The feed will fall onto the conical platform 9 and slide along the inclined surface to the surrounding area. Then, the rotation angle, speed and start / stop time of the 28BYJ48 stepper motor are preset by the control equipment such as the microcontroller. When the set feeding time is reached, the motor starts and drives the pinion 62 to rotate. The pinion 62 meshes with and drives the large gear 63 and the rotating shaft 64 to rotate, so that the moving cover 3 rotates synchronously with the rotating shaft 64. During the rotation of the moving cover 3, the limiting block 11 on its outer wall moves between the two stops 10 of the fixed cover 2 to avoid excessive rotation. When the moving cover 3 is aligned with the feed inlet 4 of the fixed cover 2, the feed falls into the chassis 1 through the feed inlet 4 and slides along the inclined surface of the chassis 1 to the feeding trough 8 on the edge. Then, the feed is guided by the feeding trough 8 to the breeding area in the fish tank.

[0051] After feeding is completed, the motor rotates in reverse according to the preset program, which drives the moving cover 3 to reset, so that the feed inlet 4 is staggered and feeding stops. If it is necessary to adjust the feeding amount or time, the control program parameters can be modified through external equipment to flexibly meet the feeding needs of zebrafish farming.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
