Description

Technical Field

[0001] This utility model relates to the field of aquaculture, specifically to a feeding mechanism for a feeding machine. Background Technology

[0002] Small-scale shrimp farming refers to the use of small sheds, which provide insulation and protection from external interference, to raise shrimp in sheds of one acre or less, achieving a short farming cycle and quick returns. Existing shrimp feeding machines mainly consist of a frame, a feed hopper fixed to the frame, a blower, a feeding pipe, and an electrical control box. During operation, a small amount of water is first added to the feed and stirred. Then, the stirred feed is placed into the feed hopper, and the feed enters the feeding pipe from the hopper's outlet. The blower then blows the feed from the feeding pipe into the water tank for feeding. However, the feed, after being stirred with water, adheres to the inner wall of the feed hopper, forming an arched structure near the outlet that prevents the feed from passing through. This arched structure not only causes feed to accumulate in the feed hopper and cannot be effectively discharged, but may also lead to spoilage due to prolonged retention, which is detrimental to shrimp growth.

[0003] Based on the above problems, the applicant applied for a utility model patent with application number "2024232721258" and titled "A Feeding Machine Suitable for Small-Scale Shrimp Farming". In use, feed falls from the lower end of the feed cylinder through the storage bin into the cylindrical feeding outer pipe. Under the rotation of the spiral spindle, the feed is transported to the outlet below the cylindrical feeding outer pipe, then falls freely into the spreading nozzle, and finally, a fan blows the feed from the two spreading pipes of the spreading nozzle into the water tank. However, in actual use, after the feed enters the first three-way connector of the spreading nozzle, it is diverted into two inclined branch pipes, and then into the corresponding spreading pipes. Due to the unstable discharge state of the feeding mechanism, if the discharge speed fluctuates or the discharge volume is too large instantaneously when the feed enters the branch pipe from the first three-way connector, the two branch pipes cannot stably distribute the feed. For example, when a large amount of feed is poured in suddenly, it may be more concentrated in one of the branch pipes, resulting in uneven feeding in a short period of time. Under the action of the blower, the amount of feed blown into the pool by the two feeding pipes is obviously uneven. Utility Model Content

[0004] The purpose of this invention is to provide a feeding mechanism for a feeder, which makes the amount of feed blown into the water tank by the two feeding pipes uniform.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A feeding machine includes a spreading mechanism, comprising a frame mounted on a pair of floats, a material cylinder mounted on the frame, a feeding mechanism located at the bottom outlet of the material cylinder, and a spreading mechanism located below the feeding mechanism. The spreading mechanism includes two spreading pipes and a blower. The spreading mechanism also includes a four-way connector and a conveying pipe. The first connector and its opposite second connector are respectively connected to the inlet ends of the two spreading pipes. A third connector, perpendicular to the first and second connectors, is connected to the outlet end of the conveying pipe. The first and second connectors are horizontal and perpendicular to each other, forming a fourth connector that forms an air inlet. The fan is mounted on the frame, and its output end is inserted into the air inlet. The inlet end of the conveying pipe is connected to the discharge port of the feeding mechanism, and the outlet end has a windproof part that extends downward into the four-way connector and contacts the bottom wall. The side of the windproof part away from the fourth connector has a notch that communicates with the two spreading pipes. The diameter of the conveying pipe is smaller than the inner diameter of the four-way connector. There is a gap between the outer wall of the windproof part and the inner wall of the four-way connector, which forms an air duct through which the air blown by the fan can pass.

[0007] In existing technologies, inconsistent feeding speeds or sudden surges in feed volume prevent stable flow distribution between the two branch pipes. The above-mentioned solution utilizes only one feed pipe, allowing feed to flow directly from the feeding mechanism to the four-way connector. Because the diameter of the feed pipe is smaller than the inner diameter of the four-way connector, a gap exists between the outer wall of the windbreak and the inner wall of the four-way connector, creating an airflow channel for the blower. The blower-generated airflow propels the feed into the water tank along the two feed pipes, preventing uneven feed amounts into both pipes. Simultaneously, rotating the feed pipes ensures even distribution of airflow within the two pipes, guaranteeing a uniform amount of feed delivered to the water tank.

[0008] In a specific embodiment of this utility model: the material conveying pipe is connected to the third connector of the four-way connector by a reducing coupling.

[0009] In a specific embodiment of this utility model: the conveying pipe is a plastic pipe with a diameter of 25mm, and the four-way connector is a PVC four-way connector with a diameter of 40mm.

[0010] In a specific embodiment of this utility model: the feeding mechanism is a horizontal screw-driven feeding mechanism, including a housing, which is divided into an upper storage bin and a lower cylindrical feeding outer tube. The cylindrical feeding outer tube has a downwardly oriented discharge port, a spiral mandrel is installed inside the cylindrical feeding outer tube, and a rotary motor for driving the spiral mandrel to rotate is installed on the outside of the cylindrical feeding outer tube.

[0011] In a specific embodiment of this utility model: a vibrator is installed on the side wall of the storage silo. Using this structure, the vibration of the vibrator causes the feed in the cylinder and storage silo to flow more smoothly into the cylindrical feeding outer pipe, effectively preventing feed bridging, reducing feed loss, and saving costs.

[0012] In a specific embodiment of this utility model: a control box is fixed on the frame, and the control box contains a controller. The rotary motor, vibrator, and fan are all electrically connected to the controller. Using the above technical solution, the controller enables automated control of feed spreading, and the distance of feed spreading is controlled by adjusting the airflow of the fan.

[0013] In a specific embodiment of this utility model: the control box is also equipped with a rechargeable battery that provides power to the controller, rotary motor, vibrator and fan.

[0014] In a specific embodiment of this utility model: a walking drive mechanism for driving the float to move on the water is connected to the frame. The walking drive mechanism includes an upper pressure wheel and a lower pressure wheel arranged on the frame. There is a gap between the upper pressure wheel and the lower pressure wheel for a traction steel wire to pass through. The traction steel wire is located in the gap and its two ends are fixed to the banks on both sides of the pool. A drive motor for driving the lower pressure wheel to rotate is also fixed on the frame. The drive motor is electrically connected to the controller.

[0015] Using the above technical solution, an upper pressure wheel and a lower pressure wheel work together to form a gap through which the traction wire can pass. The traction wire is located within the gap, with both ends fixed to the banks on both sides of the pool. When the drive motor drives the lower pressure wheel to rotate, the upper pressure wheel applies pressure to the traction wire, thus preventing the traction wire from shifting or vibrating. The rotation of the drive motor causes the lower pressure wheel to rotate, generating friction between the rotating lower pressure wheel and the traction wire, driving the lower pressure wheel to move linearly along the traction wire, thereby moving the float linearly along the traction wire. The float is moved by a walking drive mechanism for feeding, meeting diverse aquaculture needs.

[0016] In a specific embodiment of this utility model: the upper pressure wheel is a concave wheel, the lower pressure wheel is a cam, and an annular guide groove is provided on the circumferential surface of the lower pressure wheel, with the traction steel wire located within the guide groove. With this structure, the traction steel wire is positioned within the guide groove, further preventing deviation of the traction steel wire.

[0017] In summary, this utility model utilizes only one feeding pipe. Feed is fed directly from the feeding mechanism to the four-way connector via the feeding pipe. Subsequently, the wind generated by the blower blows the feed into the water tank along the two spreading pipes, preventing uneven feed amounts from entering the two spreading pipes. At the same time, by rotating the angle of the feeding pipe, the wind force of the blower is evenly distributed at the two spreading pipes, ensuring that the amount of feed blown into the water tank by the two spreading pipes is uniform.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 As shown, this utility model is a material spreading mechanism for a feeding machine. The feeding machine includes a frame 11 mounted on a pair of floats 10, a material cylinder 12 mounted on the frame 11, a feeding mechanism 20, and a spreading mechanism 30. The material cylinder 12 has a feed inlet at the top and a discharge outlet at the bottom.

[0026] Combination Figure 2As shown, in this embodiment, the feeding mechanism 20 adopts a horizontal screw-driven feeding mechanism. The feeding mechanism 20 is located at the discharge port at the bottom of the feed cylinder 12, and is used to receive the feed output from the feed cylinder 12 and convey it to the spreading mechanism 30. The feeding mechanism 20 includes a housing 201, which is divided into an upper conical storage bin 21 and a lower cylindrical feeding outer tube 22. The cylindrical feeding outer tube 22 has a downward-facing discharge port. A spiral mandrel 23 is installed inside the cylindrical feeding outer tube 22, and a rotary motor 24 for driving the spiral mandrel 23 to rotate is installed on the outside of the cylindrical feeding outer tube 22. A vibrator 25 is installed on the outer wall of the storage bin 21. In this way, the feed enters the storage bin from the discharge port of the feed cylinder. The vibration of the vibrator causes the feed in the storage bin to flow smoothly out of the discharge port of the storage bin and enter the cylindrical feeding outer pipe, preventing the feed from bridging and reducing feed loss. The rotation of the spiral spindle 23 transports the feed to the spreading mechanism 30.

[0027] Combination Figure 3 and Figure 4 As shown, in this embodiment, the material spreading mechanism 30 includes a four-way connector 31, a material conveying pipe 32, two material spreading pipes 33, and a blower 34. The first connector 311 and its opposite second connector 312 of the four-way connector 31 are respectively connected to the inlet ends of the two material spreading pipes 33. The third connector 313, perpendicular to the first and second connectors 311 and 312, is connected to the outlet end of the material conveying pipe 32. A fourth connector 314, horizontal to and perpendicular to the first and second connectors 311 and 312, forms an air inlet. The blower 34 is mounted on the frame 11, and its output end is inserted into the air inlet. The inlet end of the material conveying pipe 32 communicates with the outlet of the cylindrical feeding outer pipe 22, and the outlet end has a windbreak portion 320 that extends downward into the four-way connector 31 and contacts the bottom wall. A notch 321 communicating with the two material spreading pipes 33 is opened on the side of the windbreak portion 320 away from the fourth connector 314. The diameter of the conveying pipe 32 is smaller than the inner diameter of the four-way connector 31. There is a gap between the outer wall of the windproof part 320 and the inner wall of the four-way connector, which forms an air duct 323 through which the air blown by the fan can pass. The conveying pipe 32 and the third connector 313 of the four-way connector 31 are connected by a reducing clamp 322.

[0028] In this way, by using only one feed pipe, the feed is delivered directly from the feeding mechanism to the four-way connector after passing through the feed pipe. Since the diameter of the feed pipe 32 is smaller than the inner diameter of the four-way connector 31, there is a gap between the outer wall of the windbreak 320 and the inner wall of the four-way connector 31. This gap forms an air duct 323 through which the air blown by the blower can pass. The air generated by the blower blows the feed into the water tank along the two feed pipes, preventing uneven feed amounts entering the two feed pipes. Furthermore, during the assembly of the feed pipe 32 and the four-way connector 31, the installation angle may cause uneven distribution of the airflow from the blower in the two feed pipes, resulting in inconsistent feed amounts blown into the water tank. This can be addressed by rotating the feed pipe and observing the feed distribution in both feed pipes. When the airflow is evenly distributed in both feed pipes, the amount of feed blown into the water tank is uniform. At this point, a reducing clamp 322 is used for fixation. If the area covered by the feed blown out by one of the feed pipes is significantly larger, it indicates that the feed pipe receives more airflow. In this case, the feed pipe should be rotated in the opposite direction until the ideal balance is achieved.

[0029] In this embodiment, the feed pipe 32 is a plastic pipe with a diameter of 25mm. The four-way connector 31 is a PVC four-way connector with a diameter of 40mm.

[0030] like Figure 1 As shown, a control box 40 is fixed on the frame 11. A controller is located inside the control box 40. The rotary motor 24, fan 34, and vibrator 25 are all electrically connected to the controller. The control box 20 also contains a rechargeable battery 41 that provides power to the controller, rotary motor 24, fan 34, and vibrator 25. The rechargeable battery 41 has a low operating voltage (below 24V), eliminating the need for electric shock protection measures and ensuring that farmers are not at risk of electric shock during operation. Here, the controller can be remotely controlled to automate feeding, and the distance of feed distribution can be controlled by adjusting the fan's airflow. Simultaneously, the controller controls the automatic start-up, start-up interval, and start-up duration of the rotary motor 24, fan 34, and vibrator 25, thereby achieving scientific farming practices.

[0031] like Figure 1 and Figure 5As shown, the system also includes a driving mechanism 50 for moving the float 10 on the water. The driving mechanism 50 includes an upper pressure wheel 51 and a lower pressure wheel 52 mounted on the frame 11. A gap exists between the upper pressure wheel 51 and the lower pressure wheel 52 through which a traction wire 53 passes. The traction wire 53 is located within the gap, and fixing bolts 54 are fixed to the banks on both sides of the pool. The two ends of the traction wire 53 are fixed to the corresponding fixing bolts 54. A drive motor 55 for driving the lower pressure wheel 52 to rotate is also fixed on the frame 11. The drive motor is electrically connected to the controller, and a rechargeable battery 41 provides power to the drive motor 55. In this embodiment, the upper pressure wheel 51 is a concave wheel, and the lower pressure wheel 52 is a cam. During operation, the drive motor 55 drives the lower pressure wheel 52 to rotate. The rotating lower pressure wheel 52 generates friction with the traction wire 53, driving the lower pressure wheel 52 to move linearly along the traction wire 53, thereby causing the float 10 to move linearly along the traction wire 53. The upper pressure roller 51 can apply pressure to the traction steel wire, thereby preventing the traction steel wire from deviating or vibrating.

[0032] like Figure 5 As shown, in this embodiment, an annular guide groove 56 is provided on the circumferential surface of the pressure roller 52, and the traction steel wire 53 is located within the guide groove 56. With this structure, the traction steel wire is located within the guide groove, further preventing the traction steel wire from deviating.

[0033] During operation, the feed is mixed with water and then loaded into the feed cylinder 12. The drive motor 55 is then started, which rotates the lower pressure wheel 52. The rotating lower pressure wheel 52 generates friction with the traction steel wire 53, driving the lower pressure wheel 52 to move linearly along the traction steel wire 53, thereby causing the float 10 to move linearly along the traction steel wire 53. Simultaneously, the controller is activated using a remote control to start the rotary motor, vibrator, and blower. The feed falls from the lower outlet of the feed cylinder 12, through the storage bin, into the cylindrical feeding outer pipe 22. Then, through the rotation of the spiral spindle, the feed is conveyed to the downward-facing outlet of the cylindrical feeding outer pipe 22. The feed then falls freely, enters the four-way connector 31 through the conveying pipe 32, and finally, the blower 34 blows the feed into the water tank along the spreading pipe.

[0034] When it is necessary to move the equipment from the water surface to the shore, the control starts the drive motor 55 to drive the pressure wheel 52 to rotate. The rotating pressure wheel 52 generates friction with the traction steel wire 53, driving the pressure wheel 52 to move linearly along the traction steel wire 53, thereby driving the float 10 to move along the traction steel wire 53.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
