Description

Technical Field

[0001] The invention relates to the technical field of aquatic animal breeding, in particular to a feeding device for shrimp breeding. Background Art

[0002] Shrimp, a species of aquaculture, has attracted considerable attention from aquaculture practitioners due to its rapid growth and considerable economic value. In recent years, with the continuous advancement of aquaculture technology, the scale of shrimp farming has gradually expanded, and the stocking density has also increased accordingly, to achieve higher yields per unit area and economic benefits. In high-density aquaculture environments, the aquaculture efficiency is closely related to feeding management, because the healthy growth of shrimp is highly dependent on scientific and precise feeding management. Proper feeding not only reduces feed costs but also reduces water pollution caused by leftover bait, thereby improving the success rate of aquaculture.

[0003] In shrimp farming, traditional feeding systems suffer from concentrated distribution, leading to uneven distribution of feed among shrimp, resulting in insufficient food intake and limited growth for some individuals. Furthermore, some feed, due to inadequate distribution, is not consumed promptly and ultimately sinks to the bottom of the pond. This bottom-sinking bait not only directly wastes feed and increases farming costs, but also accumulates and decomposes over time, depleting dissolved oxygen and releasing harmful substances such as ammonia nitrogen and hydrogen sulfide, degrading water quality. Furthermore, this decaying bait creates a breeding ground for harmful microorganisms (such as Vibrio and Aeromonas), which can easily induce diseases such as enteritis and hepatopancreatic necrosis in shrimp. In severe cases, it can even lead to widespread mortality, resulting in significant economic losses for farmers. Therefore, a device that can achieve uniform feeding is urgently needed.

DETAILED DESCRIPTION

[0029] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the present invention.

[0030] Example: A feeding device for shrimp farming, such as Figure 1-Figure 3As shown, it includes: a shell 101; a mobile device 102 fixedly mounted on the bottom of the shell 101 for realizing the mobile function of the device; a charging barrel 103 fixedly mounted on the top of the shell 101 for holding bait, a top cover 1031 fixedly mounted on the top of the charging barrel 103 to prevent the bait from being contaminated, the top cover 1031 can be freely disassembled so that the bait can be replenished at any time, and a discharge port 1032 is fixedly mounted on the bottom of the charging barrel 103; a spreading pipe 104 movably mounted on the shell 101 for spreading bait, the spreading pipe 104 consists of three sections, namely, an installation section 1041, a feeding section 1042 and a nozzle 1043, the feeding section 1042 is fixed to the installation section 1041 by plug-in assembly, and the nozzle 1043 is fixed to the feeding section 1042 by threaded assembly; a feeding pipe 104 is arranged between the discharge port 1032 and the spreading pipe 104 for transmitting bait The connecting pipe 105, the upper end of the connecting pipe 105 is rotatably docked with the discharge port 1032, and the lower end of the connecting pipe 105 is fixedly connected to the feed section 1042 of the spreading pipe 104. The bait in the loading barrel 103 is added to the feed section 1042 in turn through the discharge port 1032 and the connecting pipe 105. The connecting pipe 105 adopts a hose structure, so that the connecting pipe 105 can be displaced and deformed synchronously with the displacement of the spreading pipe 104; the blower 106 is fixedly installed on the mounting section 1041. When the blower 106 is working, it will generate a high-speed airflow, thereby evenly blowing and discharging the bait stored in the spreading pipe 104. An air outlet 1061 is also provided on the mounting section 1041. When the blower 106 is running, external air is continuously inhaled through the air outlet 1061, thereby forming a stable airflow channel. In addition, the wind speed of the blower 106 is adjustable.

[0031] Start the blower 106, which blows the bait out of the feeding tube 104, thereby realizing automatic feeding of the device. When the feeding tube 104 is in a horizontal state, its feeding distance is the farthest. As the feeding tube 104 continues to rotate downward, its feeding distance decreases accordingly. In addition, the blower 106 will also affect the feeding distance. The lower the wind speed of the blower 106, the closer the bait is placed, that is, the wind speed of the blower 106 controls the farthest placement position of the feeding tube 104. In summary, in the process of feeding using the present device, the feeding tube 104 rotates back and forth horizontally at a uniform speed, and the gradual angle adjustment of the feeding tube 104 will achieve uniform feeding within a range. Adjusting the wind speed of the blower 106 will adjust the feeding area range.

[0032] Since the flat and narrow nozzle 1043 is suitable for long-distance bait spreading, and the ordinary round tube nozzle 1043 is suitable for close-range bait spreading, by setting the nozzle 1043 to be detachable, the device can easily replace the corresponding appropriate nozzle 1043 according to the actual feeding distance, thereby ensuring the operating effect of the device; in addition, by setting the feeding section 1042 to be detachable, the feeding section 1042 can be removed from the outer shell 101 during the cleaning process of the device for more convenient cleaning operation, which not only improves the cleaning effect, but the removed feeding section 1042 can also prevent cleaning water from flowing into the blower 106, thereby improving the safety of the blower 106.

[0033] like Figure 4 As shown, the device also includes: a steering mechanism arranged between the shell 101 and the material spreading pipe 104, the steering mechanism controls the material spreading pipe 104 to reciprocate horizontally, and the steering mechanism includes: a rotating seat 201 rotatably installed in the shell 101, and the direction of its rotation axis is vertical; a control ring 202 fixedly installed on the material spreading pipe 104, the control ring 202 is hingedly connected to the rotating seat 201, and the hinge axis extends along the first horizontal direction. The two will be able to rotate horizontally synchronously, which can not only make the material spreading pipe 104 rotate horizontally following the rotating seat 201, but also make the material spreading pipe 104 pitch and rotate around the rotating seat 201. The reciprocating rotation of the rotating seat 201 will realize the horizontal reciprocating steering of the material spreading pipe 104; a ground axis 203 fixedly installed at the bottom of the shell 101; a rotating frame 204 installed between the ground axis 203 and the rotating seat 201, and two support arms are provided on the rotating frame 204, one of which is rotatably connected to the ground axis 203, and the direction of its rotation axis is vertical, and the other support arm is connected to the ground axis 203. The rotating base 201 is fixedly connected, and the rotating frame 204 will reciprocate around the vertical rotation axis between the earth axis 203 and the rotating base 201, and control the rotating base 201 to reciprocate around the rotation axis; the rocking frame 205 rotatably mounted on the rotating frame 204 has its rotation axis direction in a first horizontal direction; the rocking arm 206 rotatably mounted in the housing 101 has its rotation direction in a second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction, and the end of the rocking arm 206 is rotatably connected to the end of the rocking frame 205, wherein the rotation plane of the rocking arm 206 is perpendicular to the rotation plane of the rocking frame 205, and, during the rotation of the rocking arm 206, the end of the rocking arm 206 will perform a circular cyclic displacement trajectory, the circular trajectory having the rotation axis of the rocking arm 206 as the center and a radius length equal to the arm length of the rocking arm 206; a first driving member is provided on the housing 101, the first driving member is fixed to the rotation axis of the rocking arm 206, and provides rotational power for the rotation of the rocking arm 206.

[0034] The first driving member is started to operate and control the rocker arm 206 to rotate, and the end of the rocker arm 206 forms a circular motion trajectory; since the rotation plane of the rocker arm 206 is perpendicular to the rotation plane of the rocker frame 205, the rotation movement of the rocker arm 206 can only transmit and control the rocker frame 205 to swing back and forth on the side close to the rocker arm 206. In the circular motion trajectory transmitted by the rocker arm 206, the vertical component is converted into an up and down swinging action of the rocker frame 205, and only the horizontal component is retained and transmitted to the rotating frame 204, that is, the rotating frame 204 is only driven and controlled to rotate horizontally back and forth around the rotation axis between the ground shaft 203 and the rotating seat 201, and the rotating seat 201 then realizes synchronous horizontal reciprocating rotation under the transmission of the rotating frame 204, and the ground shaft 203 is used to enhance the structural stability of the rotating frame 204. Finally, the rotating seat 201 cooperates with the control ring 202 to control the spreading pipe 104 to perform horizontal reciprocating steering.

[0035] like Figure 4 As shown, the steering mechanism also includes: a first connecting block 207 fixedly connected to the left and right sides of the rotating seat 201; a connecting ring 208 rotatably installed at the discharge port 1032, the direction of the rotation axis is vertical, the connecting pipe 105 is fixed to the connecting ring 208, and the connecting pipe 105 is rotatably docked with the discharge port 1032 through the connecting ring 208; a connecting rod 209 fixedly installed on the left and right sides of the connecting ring 208, and the lower end of each connecting rod 209 is fixedly connected to each first connecting block 207 respectively. When the spreading pipe 104 performs horizontal reciprocating rotation, it will drive the connecting pipe 105 to rotate forward and reverse relative to the discharge port 1032, avoiding frequent folding and high loss of the connecting pipe 105 due to the reciprocating rotation of the spreading pipe 104, thereby extending the service life of the connecting pipe 105.

[0036] like Figure 5-Figure 8As shown, a connecting portion 2021 is provided below the control ring 202, and the control ring 202 is hingedly connected to the rotating seat 201 through the connecting portion 2021, so that the material spreading tube 104 can pitch and rotate around the rotating seat 201. The device also includes: an angle adjustment mechanism provided between the shell 101 and the material spreading tube 104, the angle adjustment mechanism controls the rotation of the pitch angle of the material spreading tube 104, and the angle adjustment mechanism includes: a reset torsion spring 301 fixedly installed between the connecting portion of the rotating seat 201 and the control ring 202, the reset torsion spring 301 is sleeved on the rotating seat 201; a first mounting plate 302 fixedly installed in the shell 101, the first mounting plate 302 is provided below the mounting section 1041 of the material spreading tube 104, the first mounting plate 302 adopts an arc structure, and its center is on the same vertical line as the rotation axis of the rotating seat 201; a dividing bar 303 fixedly installed on the first mounting plate 302, the dividing bar 303 is divided into hierarchically arranged guide rails on the first mounting plate 302 The first mounting plate 302 is provided with a sliding shaft, and a guide block 304 is slidably mounted on the sliding shaft of the first mounting plate 302. The guide block 304 is vertically displaced. The guide block 304 adopts an inclined block structure, and its upper and lower surfaces are both set as inclined surfaces that are not perpendicular to the vertical axis. A guide block 304 is provided on one side of each layer of the dividing strip 303, and the guide blocks 304 between adjacent layers are staggered. A first return spring 305 is fixedly mounted between the guide block 304 and the first mounting plate 302. The first return spring 305 is sleeved on the sliding shaft of the first mounting plate 302; a connecting piece is arranged below the mounting section 1041; a top shaft 309 is arranged on the connecting piece, and the top shaft 309 is arranged in the guide track between the dividing strips 303. In the process of the spreading tube 104 performing horizontal reciprocating turning, the spreading tube 104 will drive the top shaft 309 to move in the guide track through the connecting piece, and the guide block 304 will guide the top shaft 309 onto the upper dividing strip 303, so that the top shaft 309 moves upward layer by layer in the guide track.

[0037] The connecting member includes: a second mounting plate 306 fixedly mounted in the housing 101, the second mounting plate 306 also adopts an arc structure, the center of which coincides with the center of the first mounting plate 302, but the diameter of the second mounting plate 306 is larger than the diameter of the first mounting plate 302; a guide frame 307 slidably mounted on the second mounting plate 306, the guide frame 307 will move back and forth along the length direction of the second mounting plate 306; a mounting block 308 slidably mounted on the guide frame 307, the mounting block 308 is vertically relative to the guide frame 307 Displacement, the guide frame 307 is used to limit the moving direction of the mounting block 308, and the top shaft 309 is provided on the mounting block 308; the sliding shaft 310 is fixedly installed on the mounting block 308, and the sliding shaft 310 and the mounting block 308 are connected by a long straight bar; the second connecting block 311 is fixedly installed below the mounting section 1041, and a sliding groove 3111 is provided in the lower part of the second connecting block 311, and the sliding shaft 310 slides with the sliding groove 3111, so that the sliding shaft 310 and the second connecting block 311 form a movable hinged cooperation relationship.

[0038] When the material spreading pipe 104 is in the process of horizontal reciprocating steering, the mounting section 1041 controls the horizontal displacement of the top shaft 309 in the guide rail through the connection relationship between the second connecting block 311, the sliding shaft 310 and the mounting block 308, and the guide frame 307 is synchronously displaced on the second mounting plate 306. When the top shaft 309 moves to the end of the dividing bar 303, the top shaft 309 will first contact the inclined surface of the lower surface of the guide block 304. During the process, contact pressure will be applied to press the guide block 304 upward and compress the first return spring 305, thereby allowing the top shaft 309 to pass under the guide block 304. Then the first return spring 305 pushes the guide block 304 to return to its original position. At the same time, the material spreading pipe 104 starts to rotate in the opposite direction and drives the top shaft 309 to move in the opposite direction. At this time, the top shaft 309 will Under the guidance of the inclined surface on the upper surface of the guide block 304, it enters the dividing bar 303 of the upper layer and the guide track of the upper layer. The mounting block 308 produces a vertical displacement relative to the guide frame 307, and the displacement distance is the width of the two dividing bars 303. The top shaft 309 then pushes the mounting section 1041 upward through the connection relationship between the second connecting block 311, the sliding shaft 310 and the mounting block 308. During the process, the sliding shaft 310 rotates and slides relative to the second connecting block 311 to ensure smooth transmission. Finally, the feeding pipe 104 is driven to complete a step adjustment of the pitch angle; as the feeding pipe 104 continues to swing back and forth, the top shaft 309 is driven upward layer by layer, thereby realizing the horizontal reciprocating turning of the feeding pipe 104 while realizing the progressive pitch angle change control of the feeding pipe 104.

[0039] like Figure 8-Figure 9As shown, among all the dividing bars 303, the dividing bar 303 at the top position is not provided with a guide block 304 on one side thereof and is provided with a guide surface 3031 guiding downward, and the position of the guide surface 3031 passes over all the dividing bars 303 below it to guide the top shaft 309 to the bottom dividing bar 303, and the angle adjustment mechanism also includes: a guide rod 3092 fixedly mounted on the mounting block 308; a central axis 3091 slidably mounted on the guide rod 3092, and the top shaft 309 is rotatably mounted on the central axis 3091; a pressure block 3093 slidably mounted on the guide rod 3092, and the pressure block 3093 is in contact with the central axis 3091; a second return spring 3094 fixedly mounted between the pressure block 3093 and the mounting block 308, and the second return spring 3094 is sleeved on the guide rod 3092.

[0040] When the feeding tube 104 is rotated at a progressive angle, the reset torsion spring 301 is gradually torsionally deformed and continuously stores energy. Under the coordinated restriction of the top shaft 309 and the partition bar 303, the reset torsion spring 301 maintains a stable elastic potential energy; until the top shaft 309 moves to the topmost partition bar 303 and contacts the guide surface 3031, indicating that the progressive angle adjustment of the feeding tube 104 has reached the final stage, at this time, the elastic recovery trend accumulated by the reset torsion spring 301 drives the top shaft 309 downward along the guide surface 3031; because the top shaft 309 needs to cross all the partition bars 303 below, that is, the top shaft guided by the guide surface 3031 The position of 309 will be closer to the edge than the position where the top shaft 309 is displaced by the feeding tube 104 under normal circumstances. Therefore, while the top shaft 309 is guided downward by the guide surface 3031, it is also squeezed and displaced relative to the mounting block 308, the pressing block 3093 is pushed, and the second return spring 3094 is compressed until the top shaft 309 returns to the lowest initial position. At this time, the feeding tube 104 is reset by the torsion spring 301 and rotated back to a horizontal state. At the same time, the second return spring 3094 pushes the middle shaft 3091 to move through the pressing block 3093, restoring the relative position between the top shaft 309 and the mounting block 308, so that the angle adjustment mechanism can operate in a cycle.

[0042] By controlling the rotation of the rotating sleeve 404, the rotating sleeve 404 rotates relative to the winding shaft 403, and the tapered crushing channel formed between the two produces a composite shearing effect on the passing bait, effectively crushing the agglomerated bait, and ensuring the fineness of the bait; by rotating the mounting shaft 402, the relative position of the winding shaft 403 and the rotating sleeve 404 is changed, and the actual size of the crushing channel is changed, that is, by performing stepless adjustment on the displacement of the mounting shaft 402, the stepless adjustment of the crushing channel is achieved to meet the processing requirements of baits of different particle sizes; when the top cover 1031 is removed, the rotating handle 405 will be synchronously disengaged from the mounting shaft 402, otherwise the top cover 1031 will reclose the loading barrel 103, and the rotating handle 405 will be re-splined with the mounting shaft 402.

[0043] like Figure 12 As shown, the first driving member includes: a transmission shaft 501 rotatably mounted in the housing 101; a worm 502 fixedly mounted on the transmission shaft 501; a worm wheel 503 rotatably mounted in the housing 101, the worm wheel 503 is fixed to the rotation axis of the rocker arm 206, and the worm wheel 503 is engaged with the worm 502; a servo motor 505 fixedly mounted in the housing 101; and transmission gears 506 fixedly mounted on the output end of the servo motor 505 and on the transmission shaft 501, respectively, and the two transmission gears 506 are engaged.

[0044] like Figure 12As shown, the transmission shaft 501 extends upward to the height of the discharge port 1032. The second driving member includes a transmission belt assembly 504 disposed between the transmission shaft 501 and the rotating sleeve 404. The transmission belt assembly 504 consists of two transmission wheels and a transmission belt wound between the two transmission wheels. One transmission wheel is rotatably mounted at the discharge port 1032 and fixed to the rotating sleeve 404, and the other transmission wheel is fixed to the upper end of the transmission shaft 501. Therefore, when the servo motor 505 is activated, its output shaft synchronously drives the rocker arm 206 and the rotating sleeve 404 to rotate, thereby integrating the uniform feeding function of the feeding pipe 104 and the bait crushing function of the rotating sleeve 404, thereby simplifying the structure of the device and reducing energy consumption.

[0045] To use this device, first, add an appropriate amount of bait into the loading barrel 103, and control the device to move to the edge of the breeding pond; then, start the servo motor 505 and the blower 106, and the bait first passes through the crushing channel formed by the twisting shaft 403 and the rotating sleeve 404, where it is agglomerated and homogenized, and then enters the spreading pipe 104, and the blower 106 blows the processed bait out of the spreading pipe 104 evenly. During this process, the spreading pipe 104 performs the following composite motions: horizontal reciprocating rotation The progressive pitch angle adjustment in the vertical direction and the vertical direction, combined with the two, will form a continuous S-shaped three-dimensional feeding trajectory. Ultimately, the device is controlled to form a fan-shaped feeding area in the breeding pond, and the bait is evenly delivered to the feeding area. The coverage of the feeding area and the feeding density can be precisely controlled by adjusting the speed of the servo motor 505 and the wind speed of the blower 106 according to the breeding needs, so as to meet the feeding needs of the shrimp and avoid the deposition of residual bait to the greatest extent, effectively improve the utilization rate of bait and reduce the risk of water pollution.

[0046] Before commissioning, the device conducts multiple tests to gather empirical data, creating a historical database. This database includes the feed range (determined by the size of the aquaculture pond), the number of aquaculture stocks, and the corresponding optimal servo motor speeds and blower air speeds. In actual operation, users can set the appropriate servo motor speed and blower air speed based on the actual size of the aquaculture pond and the number of aquaculture stocks.

[0047] It should be understood that the above description is only for illustrative purposes and is not intended to limit the present invention. Those skilled in the art will appreciate that variations of the present invention will fall within the scope of the claims herein.
