Description

Technical Field

[0001] This invention relates to the field of sturgeon farming technology, specifically to a feed dispensing device for sturgeon farming. Background Technology

[0002] Sturgeon is a general term for fish in the order Acipenseriformes. Sturgeon are distributed in the oceans and rivers of the Northern Hemisphere, with nine natural distribution areas. They are the largest, longest-lived, and oldest fish species in the world, with a history of more than 200 million years. Sturgeon farming technology involves many aspects, including site selection, facility construction, feed selection and feeding, water quality management, and disease prevention. The choice of feed is mainly based on compound feed. Feeding should adhere to the principle of small, frequent meals. The feed should be palatable, and the particle size should not be too large or too small. Generally, it is best to have a particle size of 1 / 2 of the fish's mouth. The feeding amount is about 3% of the fish's body weight, and feeding should be carried out 3-4 times a day. The feeding amount should be adjusted as needed according to the specific situation. In the current technology, it is difficult to quantitatively feed, and therefore difficult to accurately control the amount of food consumed by sturgeon.

[0003] Patent CN213463470U discloses a high-efficiency feeding device for large-scale sturgeon farming. The device features a rotating drum at the top of a support column, a feed cylinder at the top of the rotating drum, a protective shell fixedly connected to the top of the feed cylinder, a feed inlet on the outer wall of the feed cylinder, a shielding component installed at the top of the protective shell, and a motor installed inside the protective shell. A motor gear is fixedly connected to the bottom of the motor. To prevent injury to the fish, feeding should avoid excessive concentration of feed, minimizing interference between fish while they are feeding. The rotating drum allows for even feed distribution, reducing the incidence of disease. Sturgeon differ from other fish in their light requirements; direct sunlight in the water during hot summer months can negatively impact their development. Therefore, the shielding component provides shade and is easy to store and operate. While this patent addresses these issues, it still presents challenges in quantitative feeding and precise control of sturgeon intake. Therefore, a feed distribution device for sturgeon farming is proposed to solve these problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a feed spreading device for sturgeon farming, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a feed dispensing device for sturgeon farming, comprising a feeding barrel, a transmission sleeve fixedly connected to the left side of the feeding barrel, a feeding sleeve fixedly connected to the right side of the transmission sleeve, a feeding cylinder hinged to the right inner surface of the feeding barrel, a feeding port opened on the upper surface of the feeding cylinder, a feeding roller fixedly connected to the left side of the feeding cylinder, a discharge port opened on the rear side of the feeding roller, a main shaft rotatably connected to the left inner surface of the transmission sleeve, an annular clamping plate fixedly connected to the left side of the inner wall of the feeding barrel, and the feeding roller... A fan-shaped abutment block is fixedly connected to the left side of the main shaft; a toggle plate is fixedly connected to the circumferential surface of the main shaft; a mounting plate is fixedly connected to the rear side of the feeding hopper; a telescopic feeding device for adjusting the feeding distance and facilitating feeding to different fish ponds is provided below the feeding hopper; a clearing device for clearing the telescopic feeding frame and improving feeding efficiency is provided below the feeding hopper; the upper surface of the feeding sleeve is fixedly connected to the lower surface of the feeding hopper; the circumferential surface of the feeding roller is hinged to the inner surface of the annular clamping plate; a motor is fixedly connected to the left end of the main shaft, and the motor is fixedly connected to the upper surface of the mounting plate; the feeding... The front side of the feed roller and the front side of the inner wall of the feed hopper are in contact with each other. The top of the actuating plate and the inclined surface of the fan-shaped contact block are in contact with each other. A torsion spring is provided at the hinge of the feed cylinder and the feed hopper. Feed is poured into the feed cylinder through the feed inlet, and then the feed falls from the feed cylinder into the feed roller. The feed cylinder is rotated backward, which drives the feed roller to rotate inside the feed hopper. After the feed roller rotates to a certain angle, the feed inlet faces downward. At this time, the feed in the feed roller falls into the feed hopper through the feed inlet, and then slides down the inner arc surface of the feed hopper into the feed sleeve for feeding. Then, the elastic restoring action of the torsion spring drives the feed cylinder and the feed roller to rotate. When the feed is reset, the discharge port faces backward, preventing the feed from falling into the feeding hopper. The motor is then started, driving the main shaft to rotate. The main shaft in turn drives the actuating plate to rotate. The actuating plate, through the inclined surface of the fan-shaped contact block, pushes the feed roller to rotate backward along its axis. As the fan-shaped contact block rotates backward, it causes the feed roller to rotate backward within the feeding hopper, causing the discharge port to face downward. Then, the torsion spring drives the feed cylinder and the feed roller to rotate and reset. During the continuous rotation of the main shaft and the actuating plate, the fan-shaped contact block drives the feed roller and the feed cylinder to rotate and reset continuously, thus causing the feed to intermittently and automatically fall from the feed roller into the feeding hopper and the feed sleeve.

[0006] Preferably, the telescopic feeding device includes a telescopic feeding frame, a feeding port, a baffle, a connecting seat, a base plate, and an electric telescopic rod. The telescopic feeding frame is slidably connected to the inner surface of the feeding sleeve. The feeding port is located on the lower right side surface of the feeding sleeve. The baffle is fixedly connected to the upper right side surface of the telescopic feeding frame. The connecting seat is hinged to the right side surface of the transmission housing. The base plate is fixedly connected to the lower surface of the connecting seat. The electric telescopic rod is hinged to the upper surface of the base plate. The telescopic feeding device also includes a connecting shaft, a reciprocating screw, an annular partition, and a nut. The connecting shaft is fixedly connected to the lower front surface of the feed hopper. The reciprocating screw is rotatably connected to the inner surface of the connecting shaft. The annular partition is fixedly connected to the inner wall of the feed hopper. The nut is movably connected to the circumferential surface of the reciprocating screw. The top end of the electric telescopic rod is hinged to the lower surface of the mounting plate. The rear side of the baffle is in contact with the front side of the feed hopper. The left end of the reciprocating screw is fixedly connected to the right end of the main shaft. The reciprocating screw... The left side of the telescopic feeding frame rotates through the left side of the inner wall of the telescopic feeding frame. The circumferential surface of the feeding drum and the inner surface of the annular partition are in contact with each other. The left side of the nut is fixedly connected to the left side of the inner wall of the telescopic feeding frame. The feed sliding down from the feeding drum is caught by the telescopic feeding frame. At this time, the operator can adjust the distance between the feeding port on the telescopic feeding frame and the feeding sleeve by pulling out or pushing the telescopic feeding frame into the feeding sleeve. When the telescopic feeding frame is pulled out of the feeding sleeve, the electric telescopic rod is activated. After the free end of the electric telescopic rod extends, it pushes the transmission sleeve to the right through the mounting plate. The transmission sleeve then drives the feeding sleeve and the telescopic feeding frame to tilt to the right. After the telescopic feeding frame tilts, the feed can slide to the lower right. The rotation of the main shaft drives the reciprocating screw to rotate. The reciprocating screw drives the nut to move back and forth. The nut drives the telescopic feeding frame to slide back and forth in the feeding sleeve, so that the telescopic feeding frame can automatically extend and retract into the feeding sleeve.

[0007] Preferably, the unblocking device includes a telescopic slide rod, a connecting plate, and a connecting rod. The telescopic slide rod is slidably connected to the inner surface of the reciprocating screw via a spline. The connecting plate is fixedly connected to the right end of the telescopic slide rod, and the connecting rod is fixedly connected to the right side of the connecting plate. The unblocking device also includes a cleaning roller, a transmission ring, an abutting rod, and an abutting semicircular plate. The cleaning roller is fixedly connected to the circumferential surface of the connecting rod, the transmission ring is fixedly connected to the circumferential surface of the nut, the abutting rod is fixedly connected to the right side of the transmission ring, and the abutting semicircular plate is fixedly connected to the upper and lower sides of the connecting plate. The right end of the abutting rod is in contact with the left side of the connecting plate, and the right end of the abutting rod is in contact with the left side of the abutting semicircular plate. The circumferential surface of the cleaning roller is in contact with the inner surface of the telescopic feeding frame. When the reciprocating screw rotates, it drives the telescopic slide rod to rotate via the spline. The telescopic slide rod drives the connecting plate to rotate, and the connecting plate drives the connecting rod to rotate. The connecting rod rotates around the axis of the telescopic slide rod, which in turn drives the cleaning roller to rotate around the axis of the telescopic slide rod and rub against the inner wall of the telescopic feeding frame. The cleaning roller pushes the feed blocking the feeding port out of the feeding port through friction. When the nut moves to the right, it drives the transmission ring to move to the right. The transmission ring drives the abutment rod to move to the right. The abutment rod pushes the connecting plate and the abutment semicircular plate to move to the right. The connecting plate drives the telescopic slide rod to slide to the right in the reciprocating screw. At the same time, the connecting plate drives the connecting rod and the cleaning roller to move to the right. When the nut moves to the left, it drives the transmission ring and the abutment rod to move to the left. The nut also drives the telescopic feeding frame to move to the left. At this time, the inner wall of the telescopic feeding frame pushes the connecting rod and the cleaning roller to move to the left. The connecting rod drives the connecting plate to move to the left. The connecting plate then drives the telescopic slide rod to slide to the left in the reciprocating screw, so that the cleaning roller always keeps in line with the feeding port.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This feed dispensing device for sturgeon farming uses the elastic reset action of a torsion spring to rotate and reset the feed cylinder and the feeding roller. At this time, the feed outlet faces backward, and the feed in the feeding roller cannot fall into the feeding hopper, which facilitates quantitative feeding and prevents feed from being fed too quickly and causing waste. The feeding roller and the feed cylinder continue to rotate and reset, so that the feed intermittently and automatically falls from the feeding roller into the feeding hopper and the feeding sleeve, which avoids feed waste and improves feeding efficiency.

[0010] 2. This feed dispensing device for sturgeon farming allows operators to adjust the distance between the feeding port on the telescopic feeding frame and the feeding sleeve by pulling out or pushing the telescopic feeding frame into the feeding sleeve. This adjusts the dispensing distance, facilitating feed dispensing to different locations in the fishpond and improving the device's applicability. When the telescopic feeding frame is tilted, the feed can slide downwards and to the right, facilitating long-distance feed dispensing and enhancing the device's ease of use. The telescopic feeding frame can automatically extend and retract into the feeding sleeve, evenly dispensing feed to various locations in the fishpond and improving dispensing efficiency.

[0011] 3. This feed dispensing device for sturgeon farming uses a cleaning roller to push feed blocked near the feeding port out through friction, improving feeding efficiency and preventing insufficient feed from being dispensed in certain parts of the fishpond due to blockage of the telescopic feeding frame. This also improves the uniformity of feeding. The connecting plate drives the telescopic slide rod to slide to the left in the reciprocating screw, so that the cleaning roller always keeps in line with the feeding port, further preventing blockage of the feeding port and improving the unblocking effect.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-8One embodiment of the present invention is: a feed dispensing device for sturgeon farming, comprising a feeding hopper 1, a transmission sleeve 2 fixedly connected to the left side of the feeding hopper 1, a feeding sleeve 3 fixedly connected to the right side of the transmission sleeve 2, a feeding cylinder 4 hinged to the inner right side of the feeding hopper 1, a feeding port 41 opened on the upper surface of the feeding cylinder 4, a feeding roller 42 fixedly connected to the left side of the feeding cylinder 4, a discharge port 43 opened on the rear side of the feeding roller 42, and the transmission sleeve 2... A main shaft 44 is rotatably connected to the inner surface of the left side. An annular clamping plate 45 is fixedly connected to the left side of the inner wall of the feeding hopper 1. A fan-shaped abutment block 46 is fixedly connected to the left side of the feeding roller 42. A actuating plate 47 is fixedly connected to the circumferential surface of the main shaft 44. A mounting plate 48 is fixedly connected to the rear side of the feeding hopper 1. The elastic reset action of the torsion spring drives the lowering cylinder 4 and the feeding roller 42 to rotate and reset. At this time, the discharge port 43 faces backward, and the feed in the feeding roller 42 cannot fall into the feeding hopper 1, which facilitates... To prevent waste caused by feeding too quickly, a telescopic feeding device 5 is installed below the feeding hopper 1 to adjust the feeding distance and facilitate feeding to different fish ponds. A clearing device 6 is also installed below the feeding hopper 1 to clear the telescopic feeding frame 51 and improve feeding efficiency. The upper surface of the feeding sleeve 3 is fixedly connected to the lower surface of the feeding hopper 1. The circumferential surface of the feeding roller 42 is hinged to the inner surface of the annular clamping plate 45. The left end of the main shaft 44 is fixedly connected to... The motor is fixedly connected to the upper surface of the mounting plate 48. The front side of the feeding drum 42 and the front side of the inner wall of the feeding barrel 1 are in contact with each other. The top of the actuating plate 47 and the inclined surface of the fan-shaped contact block 46 are in contact with each other. A torsion spring is provided at the hinge of the feeding cylinder 4 and the feeding barrel 1. The feeding drum 42 and the feeding cylinder 4 rotate continuously and then reset, so that the feed falls intermittently and automatically from the feeding drum 42 into the feeding barrel 1 and the feeding sleeve 3, which avoids feed waste and improves feeding efficiency.

[0023] Working principle: Feed is poured into the feeding cylinder 4 through the feeding port 41, and then falls from the feeding cylinder 4 into the feeding roller 42. The feeding cylinder 4 rotates backward, causing the feeding roller 42 to rotate within the feeding hopper 1. After rotating a certain angle, the feeding port 43 faces downward. At this point, the feed in the feeding roller 42 falls through the feeding port 43 into the feeding hopper 1, and then slides down the inner curved surface of the feeding hopper 1 into the feeding sleeve 3 for feeding. Then, the elastic restoring action of the torsion spring causes the feeding cylinder 4 and the feeding roller 42 to rotate and reset. At this point, the feeding port 43 faces backward, and the feed in the feeding roller 42 cannot fall into the feeding hopper 1, facilitating quantitative feeding and preventing waste caused by feeding too quickly. The motor drives the main shaft 44 to rotate, which in turn drives the actuating plate 47 to rotate. The actuating plate 47 is pushed by the inclined surface of the fan-shaped contact block 46 to rotate backward along the axis of the feeding drum 42. When the fan-shaped contact block 46 rotates backward, it drives the feeding drum 42 to rotate backward in the feeding hopper 1, so that the discharge port 43 faces downward. Then, the torsion spring drives the discharge cylinder 4 and the feeding drum 42 to rotate and reset. During the continuous rotation of the main shaft 44 and the actuating plate 47, the fan-shaped contact block 46 drives the feeding drum 42 and the discharge cylinder 4 to rotate and reset continuously, so that the feed intermittently and automatically falls from the feeding drum 42 into the feeding hopper 1 and the feeding sleeve 3, which avoids feed waste and improves feeding efficiency.

[0024] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the telescopic feeding device 5 includes a telescopic feeding frame 51, a feeding port 52, a baffle 53, a connecting seat 54, a base plate 55, and an electric telescopic rod 56. The telescopic feeding frame 51 is slidably connected to the inner surface of the feeding sleeve 3, the feeding port 52 is opened on the lower right side surface of the feeding sleeve 3, the baffle 53 is fixedly connected to the upper right side surface of the telescopic feeding frame 51, the connecting seat 54 is hinged to the right side of the transmission sleeve 2, and the base plate 55 is fixedly connected to the lower surface of the connecting seat 54. The electric telescopic rod 56... Rod 56 is hinged to the upper surface of base plate 55. Operators can adjust the distance between the feeding port 52 on telescopic feeding frame 51 and feeding sleeve 3 by pulling out or pushing the telescopic feeding frame 51 into the feeding sleeve 3, thereby adjusting the feeding distance. This facilitates feeding at different locations in the fishpond, improving the applicability of the device. The telescopic feeding device 5 also includes a connecting shaft 57, a reciprocating screw 58, an annular partition 59, and a nut 510. The connecting shaft 57 is fixedly connected to the lower front surface of the feed hopper 1. The reciprocating screw 58 rotates to connect... The annular partition 59 is fixedly connected to the inner wall of the feed hopper 1, and the nut 510 is movably connected to the circumferential surface of the reciprocating screw 58. The top end of the electric telescopic rod 56 is hinged to the lower surface of the mounting plate 48. The rear side of the baffle 53 is in contact with the front side of the feed hopper 1. The left end of the reciprocating screw 58 is fixedly connected to the right end of the main shaft 44. The reciprocating screw 58 rotates through the left side of the telescopic feeding frame 51 and passes through the left side of the inner wall of the telescopic feeding frame 51. The circumferential surface of the feeding drum 42 is in contact with the inner surface of the annular partition 59. The left side of the nut 510 is fixedly connected to the left side of the inner wall of the telescopic feeding frame 51. When the telescopic feeding frame 51 is tilted, the feed can slide to the lower right, which facilitates long-distance feed delivery and improves the ease of use of the device. The telescopic feeding frame 51 can automatically extend and retract into the feeding sleeve 3, thereby evenly distributing the feed to various positions in the fish pond and improving the feeding efficiency. The surface of the reciprocating screw 58 is provided with a reciprocating spiral groove, and the inner wall of the nut 510 is provided with a locking block, which is located in the reciprocating spiral groove.

[0025] Working principle: Feed sliding down from the feed hopper 1 is caught by the telescopic feeding frame 51. At this time, the operator can adjust the distance between the feeding port 52 on the telescopic feeding frame 51 and the feeding sleeve 3 by pulling the telescopic feeding frame 51 out or pushing it into the feeding sleeve 3, thereby adjusting the feeding distance and facilitating feeding at different locations in the fishpond, improving the applicability of the device. When the telescopic feeding frame 51 is pulled out of the feeding sleeve 3, the electric telescopic rod 56 is activated. After the free end of the electric telescopic rod 56 extends, it pushes the transmission sleeve 2 to the right through the mounting plate 48, and the transmission sleeve 2 then... The feed sleeve 3 and the telescopic feed frame 51 are tilted to the right. After the telescopic feed frame 51 is tilted, the feed can slide to the lower right, which facilitates long-distance feed delivery and improves the ease of use of the device. The rotation of the main shaft 44 drives the reciprocating screw 58 to rotate. The reciprocating screw 58 drives the nut 510 to move back and forth. The nut 510 drives the telescopic feed frame 51 to slide back and forth in the feed sleeve 3, so that the telescopic feed frame 51 can automatically extend and retract into the feed sleeve 3, thereby evenly distributing the feed to various positions in the fish pond and improving the feeding efficiency.

[0026] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the unblocking device 6 includes a telescopic slide rod 61, a connecting plate 62, and a connecting rod 63. The telescopic slide rod 61 is slidably connected to the inner surface of the reciprocating screw 58 via a spline. The connecting plate 62 is fixedly connected to the right end of the telescopic slide rod 61, and the connecting rod 63 is fixedly connected to the right side of the connecting plate 62. The cleaning roller 64 pushes the feed blocked near the feeding port 52 out of the feeding port 52 through friction, improving the feeding efficiency and preventing insufficient feed from being fed to a certain part of the fish pond due to blockage of the telescopic feeding frame 51, thus improving the uniformity of feeding. The unblocking device 6 also includes a cleaning roller 64, a transmission ring 65, an abutment rod 66, and an abutment semicircle. Plate 67 and cleaning roller 64 are fixedly connected to the circumferential surface of connecting rod 63. Transmission ring 65 is fixedly connected to the circumferential surface of nut 510. Abutting rod 66 is fixedly connected to the right side of transmission ring 65. Abutting semicircular plate 67 is fixedly connected to the upper and lower sides of connecting plate 62. The right end of abutting rod 66 is in contact with the left side of connecting plate 62, and the right end of abutting rod 66 is in contact with the left side of abutting semicircular plate 67. The circumferential surface of cleaning roller 64 is in contact with the inner surface of telescopic feeding frame 51. Connecting plate 62 drives telescopic sliding rod 61 to slide to the left in reciprocating screw 58, so that cleaning roller 64 is always aligned with feeding port 52, further preventing the feeding port 52 from being blocked and improving the unblocking effect.

[0027] Working principle: When the reciprocating screw 58 rotates, it drives the telescopic slide rod 61 to rotate via the spline. The telescopic slide rod 61 drives the connecting plate 62 to rotate. The connecting plate 62 drives the connecting rod 63 to rotate around the axis of the telescopic slide rod 61. The connecting rod 63 then drives the cleaning roller 64 to rotate around the axis of the telescopic slide rod 61 and generate friction with the inner wall of the telescopic feeding frame 51. The cleaning roller 64 pushes the feed blocked near the feeding port 52 out of the feeding port 52 through friction, improving the feeding efficiency and preventing insufficient feed from being fed to certain parts of the fish pond due to blockage of the telescopic feeding frame 51, thus improving the uniformity of feeding. When the nut 510 moves to the right, it drives the transmission ring 65 to move to the right. The transmission ring 65 drives the abutment rod 66 to move to the right. The abutment rod 66 moves to the right through contact with the connecting plate 61. When the connecting plate 62 contacts the abutting semi-circular plate 67, it pushes the plate to the right. The connecting plate 62 drives the telescopic slide rod 61 to slide to the right within the reciprocating screw 58. At the same time, the connecting plate 62 drives the connecting rod 63 and the cleaning roller 64 to move to the right. When the nut 510 moves to the left, it drives the transmission ring 65 and the abutting rod 66 to move to the left. The nut 510 also drives the telescopic feeding frame 51 to move to the left. At this time, the inner wall of the telescopic feeding frame 51 pushes the connecting rod 63 and the cleaning roller 64 to move to the left. The connecting rod 63 drives the connecting plate 62 to move to the left. The connecting plate 62 then drives the telescopic slide rod 61 to slide to the left within the reciprocating screw 58. This ensures that the cleaning roller 64 is always aligned with the feeding port 52, further preventing the feeding port 52 from becoming blocked and improving the unblocking effect.
