[0002] With the rapid development of intensive aquaculture mode, automatic feeding machine has been widely applied in production by virtue of its advantages of saving manpower, uniform feeding and the like. However, in the actual breeding process, overfeeding is a common problem. The residual bait not only directly leads to the waste of feed and increases the breeding cost, but also can be decomposed in the water body. The decomposition process can consume a large amount of dissolved oxygen in the water and produce harmful substances such as ammonia nitrogen and nitrite, thereby deteriorating the water quality, creating conditions for the breeding of pathogenic microorganisms, and easily causing fish diseases, which seriously threatens the breeding production. Among many water quality indexes, dissolved oxygen is the most critical core parameter for measuring the health status of the water body, and is directly related to the growth and survival of the breeding organisms.

[0032] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this utility model, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-2 As shown, this embodiment provides a linkage feeding device including: a mounting frame 1, a hopper 2 disposed on the mounting frame 1, and a feeding component 3 fixed below the hopper 2 and communicating with its interior; it also includes: a mounting rod 4 fixed to the mounting frame 1, and a dissolved oxygen sensor 5 disposed on the mounting rod 4 and located below the water surface of the aquaculture farm.

[0034] The feeding assembly 3 includes: a housing 31 fixed to the bottom of the hopper 2, a microcontroller and a driving component 32 for driving the feeding, which are installed inside the housing 31;

[0035] The microcontroller is communicatively connected to the dissolved oxygen sensor 5 and the drive component 32, respectively.

[0036] By setting up a dissolved oxygen sensor 5, the change in dissolved oxygen concentration is sensed by the sensor, and the signal is transmitted to the drive component 32 through the microcontroller, so that the drive component 32 produces a corresponding preset action, thereby realizing flexible adjustment of the feeding amount.

[0037] This device has a simple structure, low component and manufacturing costs, and is easy to maintain and promote. It effectively avoids feed waste and water pollution caused by overfeeding, achieving a win-win situation for both economic and environmental benefits.

[0038] like Figures 1-2 As shown, the drive component 32 is configured as a stepper motor.

[0039] The signal output terminal of dissolved oxygen sensor 5 transmits the signal to the microcontroller, and then the microcontroller outputs a pulse signal to the stepper motor to control the rotation direction and number of steps of the stepper motor, thereby realizing the adjustment of the feeding amount.

[0040] like Figures 1-2 As shown, the feeding assembly 3 includes: a coupling disposed on the output shaft of the stepper motor, a lead screw 33 that is connected to the coupling for transmission, a lead screw nut 34 that is matched with the lead screw 33, and a baffle 35 fixed to the lead screw nut 34.

[0041] The bottom of the hopper 2 is provided with a discharge hole 21;

[0042] The width of the baffle 35 is matched with the width of the discharge hole 21.

[0043] The stepper motor rotates, causing the lead screw 33 to rotate, which in turn causes the lead screw nut 34 to move along the lead screw 33, thereby adjusting the area of ​​the baffle 35 blocking the discharge hole 21. The device is stable and reliable.

[0044] like Figures 1-3 As shown, the feeding assembly 3 further includes: a drive shaft 36 disposed at the power output end of the coupling, and a pair of driven shafts 37 that are connected to the transmission shaft.

[0045] The lead screw nut 34 and lead screw 33 are configured as a pair arranged in parallel, and the two drive shafts are respectively connected to the two lead screws 33 for transmission.

[0046] The drive shaft 36, driven shaft 37 and lead screw 33 are all connected by bevel gears 38.

[0047] The drive shaft 36, driven shaft 37, and lead screw 33 are all fixed to the inside of the housing 31 by bearings and bearing seats. The drive shaft 36 transmits power to the two drive shafts through the bevel gear 38. The two drive shafts then transmit power to the two parallel lead screws 33 through the bevel gear 38, thereby driving the two lead screw nuts 34 to move synchronously along the lead screw 33. The lead screw nuts 34 are located on both sides of the baffle 35, and together drive the baffle 35 to move, so that the force is balanced and the stability of the movement is guaranteed.

[0048] like Figures 1-2 As shown, the discharge hole 21 is configured as a strip and is inclined at a certain angle to the baffle 35. The inclined angle between the discharge hole 21 and the baffle 35 allows for a linear change in the area of ​​the discharge hole 21 being blocked during the movement of the baffle 35, which is beneficial for controlling the feeding amount. Compared to a parallel arrangement, the inclined arrangement does not affect the actual size of the device and has greater practicality. Simultaneously, the inclined arrangement causes the discharge hole 21 to be gradually blocked laterally, allowing the material to move along the unblocked discharge hole 21 during blocking, reducing movement resistance. It also prevents the material from being forced between the hopper 2 and the baffle 35, which could lead to deformation of the baffle 35 and poor sealing.

[0049] like Figures 1-2 As shown, the mounting rod 4 and the mounting frame 1 are detachably connected. The mounting rod 4 and the mounting frame 1 are connected by bolts, which facilitates the disassembly of the mounting rod 4 for maintenance and other operations such as inspection of the dissolved oxygen sensor 5, avoiding underwater operations and reducing the difficulty of maintenance for repair personnel.

[0050] like Figures 1-2 As shown, the mounting rod 4 has a sliding groove 41 on its lower side;

[0051] The slide groove 41 is provided with a slider 42 that can slide along it;

[0052] The dissolved oxygen sensor 5 is fixed to the slider 42, and a float 43 is provided at the upper end of the dissolved oxygen sensor 5.

[0053] To ensure that the dissolved oxygen sensor 5 can move with changes in water level, the float 43 is configured so that a portion of it is always above the water surface; the chute 41, slider 42 and float 43 are provided so that the dissolved oxygen sensor 5 can make adaptive adjustments with changes in water level, ensuring that its submersion depth remains basically unchanged, thus ensuring the reliability and accuracy of detection.

[0054] like Figures 1-2 As shown, the bottom of the housing 31 is provided with a detachable base plate 311.

[0055] The removable base plate 311 facilitates the inspection and cleaning of the device.

[0056] like Figures 1-2 As shown, the base plate 311 is configured with its opening tilted downwards. This prevents the material from accumulating and becoming damp within the feeding assembly 3, ensuring timely and smooth feeding.

[0057] like Figures 1-2 Figures 1-2 As shown, the housing 31 has slots 312 on both sides for placing the base plate 311. The upper end of the slot 312 is open, and the lower end is closed. The slots 312 allow the base plate 311 to be inserted downwards through the opening of the slot 312 and installed by contacting the closed part of the slot 312. The installation and disassembly are convenient, and the installation stability is effectively ensured by its own weight.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
