Description

Technical Field

[0001] This application relates to a stirring and feeding device and its working method, belonging to the technical field of aquaculture. Background Art

[0002] In the aquaculture industry, the scientific nature and efficiency of feeding operations are directly related to the growth rate, survival rate of farmed organisms, and the ecological balance of the aquaculture water body, which is the core link determining the economic benefits of aquaculture ([1] Peng Fei, Song Yulong, Zhang Limei, etc. Innovative design of aquaculture feeding boats based on TRIZ theory [J]. Feed Industry, 2023, 44(9): 8 - 13. [2] Peng Fei, Song Yulong, Huang Lijun, etc. Calibration of fish pellet feed parameters based on stacking tests [J]. Fisheries Modernization, 2025, 52(3): 43 - 52). Traditional manual feeding relies on experience. In large-scale aquaculture, not only is the labor cost high, but problems such as untimely and uneven feeding are also likely to occur, resulting in bait waste, water pollution, or unbalanced growth of farmed organisms.

[0003] Although existing mechanized feeding devices can replace manual labor to a certain extent, they have many defects. On the one hand, the functional synergy is insufficient. Most devices separate stirring and feeding. Devices with only a single feeding function cannot handle caked or unevenly sized bait, resulting in uneven feeding and pollution; devices with a stirring mechanism lack linkage control, and the stirred bait is prone to secondary caking or blockage of the feeding port, affecting the stability of feeding. On the other hand, when existing feeders are feeding bait, due to the overly large volume of raw materials and the lack of comprehensive crushing of the bait during the stirring process, the bait feeding port is blocked, affecting the normal operation of the feeder. Their stirring and processing of bait are often not very thorough, resulting in relatively large raw material particles still existing in the finished bait, leading to a decline in the quality of the bait and affecting the normal feeding of fish. Therefore, it is crucial to solve the current feeding problems, improve feeding efficiency, and aquaculture benefits. Summary of the Invention

[0004] The purpose of this application is to overcome the problems in the above background art, and provide a stirring and feeding device and its working method to improve the automation level of aquaculture, reduce aquaculture costs, and enhance feeding efficiency and aquaculture benefits.

[0005] To achieve the above purpose, this application provides the following technical solutions:

[0006] A mixing and feeding device includes a mixing device drive motor, a feeding port, an outer wall of a mixing tank, a mixing and feeding mechanism support frame, a main mixing rod feeding control cylinder, a rotary cutting blade, a feeding conveying pipe, a feeding conveying screw drive motor, a main mixing shaft, a transmission wheel drive wheel, a secondary mixing shaft fixing bracket, a transmission wheel driven wheel, a secondary mixing shaft, a first helical gear, a second helical gear, a horizontal mixing shaft, a horizontal mixing shaft fixing base, a horizontal mixing shaft fixing sleeve, a feeding screw conveying system, an upper slider, a lower slider, and a return spring.

[0007] A feed inlet is installed at the top of the outer wall of the mixing tank. A stirring device drive motor is installed at the center of the top of the outer wall of the mixing tank. Stirring and feeding mechanism support frames are installed on the left and right sides of the outer wall of the mixing tank.

A main stirring shaft is installed at the bottom of the stirring device drive motor. A transmission wheel drive wheel is installed on the upper part of the main stirring shaft. A secondary stirring shaft fixing bracket is installed above the transmission wheel drive wheel on the upper part of the main stirring shaft. A secondary stirring shaft is installed in the holes reserved on both sides of the secondary stirring shaft fixing bracket. A transmission wheel driven wheel is installed on the upper part of the secondary stirring shaft.

[0008] The driven wheel of the transmission gear system meshes with the driving wheel of the transmission gear system. A first helical gear is installed at the bottom of the auxiliary stirring shaft. Horizontal stirring shaft fixing bases are installed on both sides of the bottom of the auxiliary stirring shaft fixing bracket. A horizontal stirring shaft is installed in the reserved hole in the horizontal stirring shaft fixing base.

An upper slider is installed below the main stirring shaft, and a lower slider is installed below the upper slider. A return spring is installed below the lower slider. The return spring is installed at the bottom of the main stirring rod discharge control cylinder. The upper end face of the main stirring rod discharge control cylinder coincides with the lower end face of the horizontal stirring shaft fixing sleeve. A bait conveying pipe is installed on the side of the main stirring rod discharge control cylinder. A bait conveying screw drive motor is installed at the rear end of the linear conveying section of the bait conveying pipe. A bait screw conveying and discharging system is installed at the output end of the bait conveying screw drive motor. A rotary cutting blade is installed at the other end of the bait screw conveying and discharging system.

[0010] Preferably, the rotary cutting blade has a cutting edge on the right side of the left side portion of the rotary blade, and a cutting edge on the upper part of the right side portion of the rotary blade.

[0011] Preferably, the auxiliary stirring shaft fixing bracket has a connecting hole in the center to cooperate with the main stirring shaft; the auxiliary stirring shaft fixing bracket has a small hole on each of its left and right sides to cooperate with the auxiliary stirring shaft respectively; two long rods are fixed at the leftmost and rightmost ends, and a horizontal stirring shaft fixing base is fixed at the end of the long rods.

[0012] Preferably, the horizontal stirring shaft fixing base, the horizontal stirring shaft, and the hole on the horizontal stirring shaft fixing sleeve are coaxial.

[0013] Preferably, the reset spring is fixed to the bottom of the main stirring rod discharge control cylinder, and the lower slider is fixed above the reset spring.

[0014] This application also provides a method for operating the mixing and feeding device, including:

[0015] Add bait ingredients to the bait inlet;

[0016] The stirring device drive motor rotates counterclockwise to enter the stirring mode: the main stirring shaft rotates counterclockwise under the action of the stirring device drive motor, the drive wheel of the transmission gear system installed on the main stirring shaft drives the driven wheel of the transmission gear system to rotate clockwise, and the driven wheel of the transmission gear system further drives the auxiliary stirring shaft to rotate; the rotation of the auxiliary stirring shaft drives the first helical gear installed at its bottom to rotate, and then drives the second helical gear to rotate, thereby realizing the circular propulsion and stirring of the bait;

[0017] In stirring mode, the drive wheel of the transmission gear system drives the driven wheel of the transmission gear system to rotate clockwise. Under the action of the auxiliary stirring shaft fixing bracket, the auxiliary stirring shaft will perform planetary motion around the main stirring shaft, further stirring the excess bait on the inner side of the outer wall of the mixing tank. Two long rods are welded to the leftmost and rightmost ends of the auxiliary stirring shaft fixing bracket to stir the excess bait close to the inner side of the outer wall of the mixing tank, making the stirring more uniform.

[0018] During the mixing process, under the combined action of the main mixing shaft, the secondary mixing shaft, and the horizontal mixing shaft, large pieces of bait raw materials are crushed and mixed with small pieces of bait raw materials and granular bait raw materials to form finished bait; the bait raw materials on the left side of the main mixing shaft in the mixing tank rotate counterclockwise, while the bait raw materials on the right side of the main mixing shaft rotate clockwise.

[0019] After the bait is fully mixed, the stirring device drive motor rotates clockwise to enter the feeding mode: the main stirring shaft rotates clockwise under the action of the stirring device drive motor, the drive wheel of the transmission wheel system installed on the main stirring shaft drives the driven wheel of the transmission wheel system to rotate counterclockwise, and the driven wheel of the transmission wheel system further drives the auxiliary stirring shaft to rotate; the rotation of the auxiliary stirring shaft drives the first helical gear installed at its bottom to rotate, and then drives the second helical gear to rotate;

[0020] In the feeding mode, the main stirring shaft rotates clockwise under the action of the stirring device drive motor. The spiral blades on the main stirring shaft push the bait downward. At the same time, under the combined action of the auxiliary stirring shaft and the horizontal stirring shaft, the bait on the left side of the main stirring shaft rotates clockwise, and the bait on the right side of the main stirring shaft rotates counterclockwise. The bait in the mixing tank is continuously transported to the main stirring shaft and fed down under the action of the main stirring shaft.

[0021] The finished bait, once mixed, falls downwards into the horizontal mixing shaft fixing sleeve under the action of the main mixing shaft. The rotation of the main mixing shaft drives the upper slider installed at the bottom of the main mixing shaft to rotate. The upper slider and the lower slider cooperate with each other, and under the action of the return spring, the upper slider moves up and down continuously. When the upper slider is in the high position, the opening on the horizontal mixing shaft fixing sleeve will close, and the bait will not be able to enter the bait conveying pipe. When the upper slider is in the low position, the opening on the horizontal mixing shaft fixing sleeve will open, and the bait will enter the bait conveying pipe to continue feeding.

[0022] Under the action of extrusion, the bait enters the bait conveying pipe. The bait screw conveying and dropping system starts to rotate under the drive of the bait conveying screw drive motor. The bait is pushed and dropped by the pushing force of the bait screw conveying and dropping system. When the bait moves to the end of the bait conveying pipe, the rotating cutting blade installed at the end of the bait screw conveying and dropping system cuts the bait and completes the dropping.

[0023] This application achieves thorough and uniform mixing, improving bait quality: The device employs a mixing structure with a main mixing shaft, a secondary mixing shaft, and a horizontal mixing shaft working in tandem, enabling comprehensive and deep mixing of the bait ingredients. When the main mixing shaft rotates, the transmission wheel system drives the secondary mixing shaft to not only rotate itself but also perform planetary motion around the main mixing shaft. Combined with the long rods at both ends of the secondary mixing shaft's fixed support, this thoroughly agitates excess bait on the inner side of the mixing tank, effectively preventing bait residue on the tank wall and avoiding mixing dead zones. Simultaneously, during the mixing process, the bait on both sides of the main mixing shaft rotates counterclockwise and clockwise respectively, creating convection mixing. This thoroughly breaks down large pieces of bait ingredients, uniformly mixing them with smaller pieces and granules, significantly improving the uniformity of the finished bait and ensuring bait quality.

[0024] This application ensures smooth and controllable feeding, avoiding clogging issues: The device switches between mixing and feeding modes by rotating the mixing motor. In feeding mode, the spiral blades on the main mixing shaft push the bait downwards, while the combined action of the auxiliary and horizontal mixing shafts causes the bait to converge towards the main mixing shaft, ensuring a continuous and stable supply of bait to the feeding structure. Furthermore, the up-and-down movement of the upper and lower sliders under the action of the return spring controls the opening and closing of the horizontal mixing shaft's fixed sleeve, enabling intermittent feeding. This avoids clogging caused by a large influx of bait at once and allows for precise control of the feeding amount. The driving force of the bait screw conveyor feeding system and the cutting action of the rotating cutting blades at the end further ensure smooth movement of the bait within the conveying pipe and the uniformity of the final feeding, completely solving the problem of easy clogging at the feeding port of traditional feeding devices.

[0025] This application achieves coordinated mixing and feeding to improve overall efficiency: the device integrates mixing and feeding functions. Changes in the direction of the mixing motor directly drive the coordinated action of the mixing and feeding components, allowing the mixed feed to quickly and orderly enter the feeding stage, reducing time loss during intermediate transport and the risk of secondary feed clumping. Simultaneously, mixing and feeding parameters can be adjusted collaboratively through motor operation, flexibly adapting to different feed characteristics and aquaculture needs. This significantly reduces operational complexity, improves the automation level of feeding and overall work efficiency, and better meets the requirements of modern intensive and precise aquaculture.

[0026] This application features a rational structural design and wide applicability: the components of the device are compactly arranged, and the transmission relationships are clearly defined. Power is efficiently transmitted through gears and wheel systems, ensuring the stability and reliability of each mechanism's operation. Whether dealing with easily agglomerated feed, unevenly sized raw materials, or feed with varying viscosities, this device can effectively handle the feeding through agitation and a smooth feeding process. Its wide applicability meets the feeding needs of various aquaculture scenarios, providing strong support for improving aquaculture efficiency.

[0027] The mixing, feeding, and discharging device and its working method provided in this application have the following advantages compared with the prior art:

[0028] 1. During the mixing process of this application, the drive wheel of the transmission gear system drives the driven wheel of the transmission gear system to rotate clockwise. Under the action of the auxiliary stirring shaft fixing bracket, the auxiliary stirring shaft will perform planetary motion around the main stirring shaft, further stirring the excess bait on the inner side of the outer wall of the mixing tank. Two long rods are welded to the leftmost and rightmost ends of the auxiliary stirring shaft fixing bracket to stir the excess bait close to the inner side of the outer wall of the mixing tank, making the mixing more uniform.

[0029] 2. During the feeding process of this application, the main stirring shaft rotates clockwise under the action of the stirring device drive motor. The spiral blades on the main stirring shaft push the bait downward. At the same time, under the combined action of the auxiliary stirring shaft and the horizontal stirring shaft, the bait on the left side of the main stirring shaft rotates clockwise, and the bait on the right side of the main stirring shaft rotates counterclockwise. The bait in the mixing tank is continuously transported to the main stirring shaft and fed out under the action of the main stirring shaft.

[0030] 3. During the mixing process, the horizontal stirring shaft and the auxiliary stirring shaft not only rotate around their own axes, but also revolve around the main stirring shaft, which makes the feed inside the outer wall of the mixing tank more thoroughly mixed.

[0031] 4. The upper and lower sliders, along with a return spring, are used to control the amount of bait falling. The amount and speed of the falling bait are adjusted by the speed of the motor driven by the stirring device, which allows for better control of the falling bait.

[0032] 5. The mixing, feeding, and discharging device of this application has good safety performance and high working efficiency; it can reduce the workload of workers mixing, feeding, and discharging, and improve the mechanization and automation level of feeding and discharging.

[0052] Preferably, the horizontal stirring shaft fixing base 309, the horizontal stirring shaft 308 and the hole on the horizontal stirring shaft fixing sleeve 310 are coaxial.

[0053] The working process of this application is as follows: Add bait raw materials into the bait inlet 102;

[0054] The stirring device drive motor 101 rotates counterclockwise, entering the stirring mode: the main stirring shaft 301 rotates counterclockwise under the action of the stirring device drive motor 101, the transmission gear drive wheel 302 installed on the main stirring shaft 301 drives the transmission gear driven wheel 304 to rotate clockwise, and the transmission gear driven wheel 304 further drives the auxiliary stirring shaft 305 to rotate; the rotation of the auxiliary stirring shaft 305 drives the first helical gear 306 installed at its bottom to rotate, and then drives the second helical gear 307 to rotate, thereby realizing the circular propulsion and stirring of the bait;

[0055] In the stirring mode, the drive wheel 302 of the transmission wheel system drives the driven wheel 304 of the transmission wheel system to rotate clockwise. Under the action of the auxiliary stirring shaft fixing bracket 303, the auxiliary stirring shaft 305 will perform planetary motion around the main stirring shaft 301, further stirring the excess bait on the inner side of the outer wall 103 of the mixing tank. Two long rods are welded to the leftmost and rightmost ends of the auxiliary stirring shaft fixing bracket 303 to stir the excess bait close to the inner side of the outer wall 103 of the mixing tank, making the stirring more uniform.

[0056] During the mixing process, under the combined action of the main mixing shaft 301, the auxiliary mixing shaft 305, and the horizontal mixing shaft 308, large pieces of bait raw materials are crushed and mixed with small pieces of bait raw materials and granular bait raw materials to form finished bait; the bait raw materials on the left side of the main mixing shaft 301 in the mixing tank rotate counterclockwise, while the bait raw materials on the right side of the main mixing shaft 301 rotate clockwise.

[0057] After the bait is fully mixed, the stirring device drive motor 101 rotates clockwise to enter the feeding mode: the main stirring shaft 301 rotates clockwise under the action of the stirring device drive motor 101, and the transmission wheel drive wheel 302 installed on the main stirring shaft 301 drives the transmission wheel driven wheel 304 to rotate counterclockwise. The transmission wheel driven wheel 304 further drives the auxiliary stirring shaft 305 to rotate; the rotation of the auxiliary stirring shaft 305 drives the first helical gear 306 installed at its bottom to rotate, which in turn drives the second helical gear 307 to rotate.

[0058] In the feeding mode, the main stirring shaft 301 rotates clockwise under the action of the stirring device drive motor 101. The spiral blades on the main stirring shaft 301 push the bait downward. At the same time, under the combined action of the auxiliary stirring shaft 305 and the horizontal stirring shaft 308, the bait on the left side of the main stirring shaft 301 rotates clockwise, and the bait on the right side of the main stirring shaft 301 rotates counterclockwise.

The rotation of the main mixing shaft 301 drives the upper slider 312 installed at the bottom of the main mixing shaft 301 to rotate. The upper slider 312 and the lower slider 313 cooperate with each other, and under the action of the return spring 314, the upper slider 312 moves up and down continuously. When the upper slider 312 is in the high position, the opening on the horizontal mixing shaft fixing sleeve 310 will be closed, and the bait will not be able to enter the bait conveying pipe 201. When the upper slider 312 is in the low position, the opening on the horizontal mixing shaft fixing sleeve 310 will be opened, and the bait will enter the bait conveying pipe 201 to continue the bait falling process.

[0060] Under the action of extrusion, the bait enters the bait conveying pipe 201. The bait screw conveying and dropping system 311 starts to rotate under the drive of the bait conveying screw drive motor 202. The bait is pushed and dropped by the driving force of the bait screw conveying and dropping system 311. When the bait moves to the end of the bait conveying pipe 201, the rotating cutting blade 106 installed at the end of the bait screw conveying and dropping system 311 cuts the bait and completes the dropping.

The working method of the mixing and feeding device according to claims 1-5, characterized in that, Add bait ingredients to the bait inlet (102); The stirring device drive motor (101) rotates counterclockwise to enter the stirring mode: the main stirring shaft (301) rotates counterclockwise under the action of the stirring device drive motor (101), the transmission wheel drive wheel (302) installed on the main stirring shaft (301) drives the transmission wheel driven wheel (304) to rotate clockwise, and the transmission wheel driven wheel (304) further drives the auxiliary stirring shaft (305) to rotate; the rotation of the auxiliary stirring shaft (305) drives the first helical gear (306) installed at its bottom to rotate, and then drives the second helical gear (307) to rotate, thereby realizing the circular propulsion and stirring of the bait; In the stirring mode, the drive wheel (302) of the transmission wheel system drives the driven wheel (304) of the transmission wheel system to rotate clockwise. Under the action of the auxiliary stirring shaft fixing bracket (303), the auxiliary stirring shaft (305) will perform planetary motion around the main stirring shaft (301) to further stir the excess bait on the inner side of the outer wall (103) of the mixing tank. Two long rods are welded to the leftmost and rightmost ends of the auxiliary stirring shaft fixing bracket (303) to stir the excess bait close to the inner side of the outer wall (103) of the mixing tank, making the stirring more uniform. During the mixing process, under the combined action of the main mixing shaft (301), the auxiliary mixing shaft (305), and the horizontal mixing shaft (308), large pieces of bait raw materials are crushed and mixed with small pieces of bait raw materials and granular bait raw materials to form finished bait; the bait raw materials on the left side of the main mixing shaft (301) in the mixing tank rotate counterclockwise, and the bait raw materials on the right side of the main mixing shaft (301) rotate clockwise; After the bait is fully mixed, the stirring device drive motor (101) rotates clockwise and enters the feeding mode: the main stirring shaft (301) rotates clockwise under the action of the stirring device drive motor (101), the transmission wheel drive wheel (302) installed on the main stirring shaft (301) drives the transmission wheel driven wheel (304) to rotate counterclockwise, and the transmission wheel driven wheel (304) further drives the auxiliary stirring shaft (305) to rotate; the rotation of the auxiliary stirring shaft (305) drives the first helical gear (306) installed at its bottom to rotate, and then drives the second helical gear (307) to rotate; In the feeding mode, the main stirring shaft (301) rotates clockwise under the action of the stirring device drive motor (101). The spiral blades on the main stirring shaft (301) push the bait downward. At the same time, under the combined action of the auxiliary stirring shaft (305) and the horizontal stirring shaft (308), the bait on the left side of the main stirring shaft (301) rotates clockwise, and the bait on the right side of the main stirring shaft (301) rotates counterclockwise. The bait in the mixing tank is continuously transported to the main stirring shaft and fed down under the action of the main stirring shaft. The finished bait, after being mixed, falls downward into the horizontal stirring shaft fixing sleeve (310) under the action of the main stirring shaft (301).
