Description

Technical Field

[0001] This utility model relates to the field of fish farming technology, and in particular to an automatic feeding device for fish farming. Background Technology

[0002] Fish fry farming is the process of raising fish fry into edible or release-ready fingerlings. Fish fry are delicate, poorly adaptable to their environment, have a narrow diet, weak initiative in feeding, and are prone to mortality and predation. Therefore, they must be carefully fed and managed in a small, artificially controlled body of water to grow into robust fingerlings of a certain size. Feeding fry is a crucial part of the fish farming process.

[0003] However, in the current technology, most fish fry are fed by manually throwing food. This method is labor-intensive, and feeding at fixed times and in fixed quantities is troublesome. In addition, the range and location of throwing fish food are not fixed, which can easily affect the feeding of fish fry and thus affect the breeding effect.

[0004] To address this issue, an automatic feeding device for fish farming was proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic feeding device for fish farming, comprising: a storage tank, an installation component on the surface of the storage tank, a discharge switch device in the inner cavity of the storage tank, a discharge pipe installed through the bottom of the storage tank, a connecting component at one end of the discharge pipe, two rotating devices on the surface of the bottom of the storage tank, and a throwing device at one end of the connecting component.

[0007] In a preferred embodiment, a cross support frame is fixedly installed at the bottom of the inner cavity of the storage tank, a mounting circular plate is fixedly installed at the center of the cross support frame, and a protective shell is fixedly installed at the top of the mounting circular plate.

[0008] In a preferred embodiment, the mounting assembly includes a mounting base, a C-shaped support rod fixedly mounted on one side of the mounting base, and a fixing collar fixedly mounted on one end of the C-shaped support rod, the fixing collar being fixedly fitted onto the bottom of the surface of the storage tank.

[0009] In a preferred embodiment, the discharge switch device includes a forward and reverse motor located inside the protective housing. The bottom of the forward and reverse motor is fixedly mounted on the top of the mounting circular plate. The output end of the forward and reverse motor passes through the surface of the protective housing via a bearing and is fitted with a threaded rod. A spherical gate valve is threaded onto the surface of the threaded rod. Limiting rods movably pass through both sides of the surface of the spherical gate valve. The tops of the two limiting rods are respectively mounted on both sides of the bottom of the mounting circular plate.

[0010] In a preferred embodiment, the connecting assembly includes an L-shaped connecting pipe, the top end of which is sleeved on the surface of the bottom of the discharge pipe via a bearing, and a toothed ring is fixedly sleeved on the surface of the top end of the L-shaped connecting pipe.

[0011] In a preferred embodiment, both of the rotating devices include mounting plates, which are respectively fixedly installed on both sides of the bottom of the storage tank. A motor is fixedly installed on the bottom of each of the two mounting plates, and a sector gear is fixedly installed on the output end of each of the two motors. The surfaces of the two sector gears are alternately meshed with the surfaces of the gear ring.

[0012] In a preferred embodiment, the throwing device includes a throwing tube, a check valve is embedded in one end of the inner cavity of the throwing tube, a blower is fixedly connected to one end of the throwing tube, a connecting pipe is fixedly installed on one side of the surface of the throwing tube, one end of the connecting pipe is sleeved on the discharge end of the L-shaped connecting pipe through a bearing, and a plurality of bolt holes are opened on one end of the surface of the connecting pipe.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, a forward and reverse motor drives a threaded rod to rotate. Under the limit of the limit rod, the ball gate valve moves up and down to open and close the discharge port at the bottom of the storage tank. Fish food inside the storage tank falls into the feeding pipe through the L-shaped connecting pipe and the connecting pipe. Under the action of the blower, the check valve will open, and the wind generated by the blower will blow the fish food falling into the feeding pipe out and onto the water surface to complete the feeding work, saving manpower for timed and quantitative feeding.

[0015] 2. In this utility model, when the blower is started to feed the fish, the motors on both sides of the bottom of the storage tank will start in opposite directions at the same time, and the two sector gears will alternately mesh with the surface of the connecting gear ring. Driven by the motor, the L-shaped connecting pipe will rotate back and forth on both sides, so as to fix the feeding range and position of the feeding pipe, so that the fish fry form a fixed feeding area and improve the breeding effect.

Detailed Implementation

[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] Please see Figure 1-5 This utility model provides a technical solution: an automatic feeding device for fish farming, comprising: a storage tank 1, an installation component 2 on the surface of the storage tank 1, a discharge switch device 3 in the inner cavity of the storage tank 1, a discharge pipe 104 through the bottom of the storage tank 1, a connecting component 4 at one end of the discharge pipe 104, two rotating devices 5 on the surface of the bottom of the storage tank 1, and a throwing device 6 at one end of the connecting component 4.

[0025] Specifically: Mounting component 2 provides support for the storage tank 1. Discharge switch device 3 controls the opening and closing of the discharge port inside the storage tank 1. Connecting component 4 and rotating device 5 work together to control the reciprocating movement of the throwing pipe 601, and the throwing device 6 realizes the throwing and feeding operation.

[0026] In one embodiment, a cross support frame 101 is fixedly installed at the bottom of the inner cavity of the storage tank 1, a mounting circular plate 102 is fixedly installed at the center of the cross support frame 101, and a protective shell 103 is fixedly installed at the top of the mounting circular plate 102.

[0027] Specifically: the cross support frame 101 and the mounting plate 102 serve to support the discharge switch device 3, and the protective shell 103 serves to shield the forward and reverse motors 301 and facilitate the slippage of fish food.

[0028] In one embodiment, the mounting assembly 2 includes a mounting base 201, a C-shaped support rod 202 is fixedly mounted on one side of the mounting base 201, and a fixing collar 203 is fixedly mounted on one end of the C-shaped support rod 202. The fixing collar 203 is fixedly sleeved on the bottom of the surface of the storage tank 1.

[0029] Specifically: the mounting base 201 provides support and fixation, the C-shaped support rod 202 provides connection, and the fixing collar 203 connects and supports the storage tank 1.

[0030] In one embodiment, the discharge switch device 3 includes a forward and reverse motor 301, which is located inside the protective housing 103. The bottom of the forward and reverse motor 301 is fixedly installed on the top of the mounting circular plate 102. The output end of the forward and reverse motor 301 passes through the surface of the protective housing 103 through a bearing and is equipped with a threaded rod 302. A ball gate valve 304 is threadedly fitted on the surface of the threaded rod 302. Limiting rods 303 are movably passed through both sides of the surface of the ball gate valve 304. The tops of the two limiting rods 303 are respectively installed on both sides of the bottom of the mounting circular plate 102.

[0031] Specifically: After the forward and reverse motor 301 starts, it drives the threaded rod 302 to rotate. Under the limit of the limit rod 303, the ball gate valve 304 moves up and down. The diameter of the ball gate valve 304 is larger than the diameter of the bottom outlet of the storage tank 1. The up and down movement realizes the opening and closing of the bottom outlet of the storage tank 1.

[0032] In one embodiment, the connecting component 4 includes an L-shaped connecting pipe 401, the top end of which is sleeved on the surface of the bottom of the discharge pipe 104 via a bearing, and a toothed ring 402 is fixedly sleeved on the surface of the top end of the L-shaped connecting pipe 401.

[0033] Specifically: The L-shaped connecting pipe 401 is installed at the bottom of the discharge pipe 104 via a bearing for easy rotation.

[0034] In one embodiment, both rotating devices 5 include mounting plates 501, which are fixedly mounted on both sides of the bottom of the storage tank 1. Motors 502 are fixedly mounted on the bottom of both mounting plates 501, and sector gears 503 are fixedly mounted on the output ends of both motors 502. The surfaces of the two sector gears 503 are alternately meshed with the surface of the gear ring 402.

[0035] Specifically: the two motors 502 start synchronously in opposite directions, driving the two sector gears 503 to rotate synchronously in opposite directions. The two sector gears 503 alternately mesh on the surface of the gear ring 402, driving the L-shaped connecting pipe 401 to move back and forth. The rotation speed of the motors 502 is controlled within a certain range so that the L-shaped connecting pipe 401 and the throwing pipe 601 will not rotate too much due to inertia when rotating.

[0036] In one embodiment, the throwing device 6 includes a throwing tube 601, a check valve 602 is installed at one end of the inner cavity of the throwing tube 601, a blower 603 is fixedly connected to one end of the throwing tube 601, a connecting tube 604 is fixedly installed on one side of the surface of the throwing tube 601, one end of the connecting tube 604 is sleeved on the discharge end of the L-shaped connecting tube 401 through a bearing, and a plurality of bolt holes 605 are opened at one end of the surface of the connecting tube 604.

[0037] Specifically: the check valve 602 is normally closed in the feeding pipe 601. After the blower 603 is started, it is opened by the wind force, so that the wind force of the blower 603 blows into the feeding pipe 601, blowing out the fish food that falls into the feeding pipe 601 and scattering it on the water surface. The connecting pipe 604 is installed at one end of the L-shaped connecting pipe 401 through the bearing. It is fixed by installing bolts in the bolt hole 605 and tightening them to squeeze them onto the surface of the L-shaped connecting pipe 401, which facilitates the adjustment of the scattering angle.

[0038] Working Principle: Before using this device, first fix the mounting base 201 in the feeding area and connect the device to an external power source. Position the initial position of the feeding pipe 601 towards the middle of the feeding area. When feeding the fish, pre-set the timed and quantitative feeding parameters and start the feeding program via the external control terminal. The forward and reverse motors 301 and the blower 603 start, driving the threaded rod 302 to rotate. Under the limit of the limit rod 303, the ball gate valve 304 moves upward away from the bottom outlet of the storage tank 1, causing the fish food inside the storage tank 1 to fall into the discharge pipe 104 and the L-shaped connecting pipe 401. Then, it falls into the feeding pipe 601 through the connecting pipe 604. Under the action of the blower 603, the check valve 602 will... When the blower 603 is turned on, the air force generated by the blower 603 blows the fish food that has fallen into the feeding pipe 601 out and onto the water surface to complete the feeding work. After the set time is reached, the forward and reverse motors 301 will start first, driving the ball gate valve 304 to reset and block the bottom outlet of the storage tank 1. Then the blower 603 will be turned off, saving manpower for timed and quantitative feeding. When the blower 603 is turned on to feed, the motors 502 on both sides of the bottom of the storage tank 1 will start in reverse at the same time, and the two sector gears 503 will alternately mesh with the surface of the connecting gear ring 402. Driven by the motors 502, the L-shaped connecting pipe 401 will rotate back and forth on both sides, so that the feeding range and position of the feeding pipe 601 can be fixed, so that the fish fry form a fixed feeding area and improve the breeding effect.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
