Description

Technical Field

[0001] This utility model relates to the field of aquaculture, specifically to an automatic feeding machine with a V-shaped track for shrimp farming in small sheds. Background Technology

[0002] Small-scale shrimp farming refers to the use of small sheds, which provide insulation and are undisturbed by external factors, to raise shrimp in sheds of one acre or less, resulting in a short farming cycle and quick returns. Currently, small-scale shrimp farmers typically build multiple sheds depending on the farming area. Each shed usually consists of two small ponds. To maximize the area for shrimp farming, the walkways between the two ponds are usually quite narrow. Traditional small-scale shrimp farming mostly relies on manual feeding or the use of feeders that can move on the water surface.

[0003] Manual feeding involves workers carrying buckets of bait and scattering it along the walkway with spoons, feeding one shed at a time before moving on to the next. However, this method requires significant physical strength, and because the walkways are narrow, prolonged work can lead to worker exhaustion and a risk of falling into the pool.

[0004] To reduce the impact of strong winds on the shed and prevent it from collapsing, a feeding machine capable of moving on water is used. This requires adding numerous diagonal braces to ensure the overall stability of the shed. However, too many diagonal braces interfere with the feeding machine's movement on the water, making it very inconvenient. Utility Model Content

[0005] Based on this, and in response to the above problems, this utility model provides an automatic feeding machine with a V-shaped track for shrimp farming in small sheds.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An automatic feeder with a V-shaped track for shrimp farming in small sheds includes a movable trolley, a feed cylinder mounted on the movable trolley, a horizontal screw-driven feeding mechanism, and a feeding mechanism. The horizontal screw-driven feeding mechanism is located at the discharge port at the bottom of the feed cylinder and is used to receive the feed output from the feed cylinder and convey it to the feeding mechanism. It also includes a pair of tracks fixed on a walkway. The bottom surface of the movable trolley is provided with two drive wheels and two driven wheels. A drive motor for driving the two drive wheels to rotate is fixed on the movable trolley, and all wheels are located on the corresponding tracks.

[0008] With the above structure, only two tracks need to be laid on the pedestrian walkway of the small shed. The movable trolley is placed on the two tracks, and the movement path of the movable trolley can be controlled, thus avoiding interference from the diagonal bracing when the feeding machine moves on the water surface.

[0009] In a specific embodiment of this utility model: the cross-section of the track is inverted V-shaped, the driving wheel is a nylon wheel, and the driven wheel is a stainless steel wheel; all wheels are secured to their corresponding tracks. Using this technical solution, the V-shaped track saves material and reduces costs compared to a square groove track; the nylon wheel reduces energy consumption and is also inexpensive.

[0010] In a specific embodiment of this utility model: the horizontal screw propulsion feeding mechanism includes a housing, which is divided into an upper storage bin and a lower cylindrical feeding outer tube. The cylindrical feeding outer tube has a downward-facing 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. A vibrator is installed on the side wall of the storage bin. With this structure, the vibration of the vibrator causes the feed in the cylinder and storage bin to flow, thus allowing it to fall more smoothly into the cylindrical feeding outer tube, effectively preventing feed bridging, reducing feed loss, and saving costs.

[0011] In a specific embodiment of this utility model: the material spreading mechanism includes a material spreading nozzle and a blower. The material spreading nozzle has an inlet that communicates with the outlet of the cylindrical feeding pipe and two material spreading nozzles facing outward. An air inlet is also provided between the two material spreading nozzles of the material spreading nozzle. The blower is mounted on the frame and its output end is inserted into the air inlet.

[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 drive motor, 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, drive motor, vibrator and fan.

[0014] In summary, this invention, through the use of a movable trolley and track, enables self-propelled operation without manual pushing or driving, thus reducing human intervention. The use of V-shaped tracks and nylon wheels for drive is inexpensive, further reducing costs. By installing vibrators on the side walls of the storage hopper, the vibrations cause the feed in the cylinder and storage hopper to flow more smoothly into the cylindrical feeding pipe, effectively preventing feed bridging, reducing feed loss, and saving costs. A controller automates the feeding process, controlling the distance the feed is thrown by adjusting the fan's airflow. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1 As shown, this utility model is an automatic feeder with a V-shaped track for shrimp farming in small sheds, including a movable trolley 11, a feed cylinder 12 mounted on the movable trolley 11, a horizontal screw propulsion feeding mechanism 20, and a spreading mechanism 30. The feed cylinder 12 has a feed inlet at the top and a discharge outlet at the bottom.

[0022] Combination Figure 2As shown, the horizontal screw propulsion feeding mechanism is located at the discharge port at the bottom of the feed cylinder 12, used to receive the feed output from the feed cylinder 12 and convey it to the spreading mechanism 30. The horizontal screw propulsion feeding mechanism includes a housing 201. The housing 201 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. When feeding shrimp, a small amount of water needs to be added to the feed and stirred before the stirred feed is put into the feed cylinder. However, the feed stirred with water will adhere to the inner wall of the feed cylinder, resulting in an insurmountable arched structure near the discharge port of the feed cylinder. Furthermore, the arching structure not only causes feed to accumulate in the feed cylinder and fail to be effectively discharged, but may also lead to spoilage due to prolonged feed retention, which is detrimental to shrimp growth. With this structure, feed enters the storage hopper from the feed cylinder's outlet. Vibration from the vibrator causes the feed to flow smoothly within the feed cylinder and storage hopper, allowing it to flow smoothly out of the storage hopper's outlet and into the cylindrical feeding outer pipe. This effectively prevents feed arching, reduces feed loss, and the rotating spiral spindle 23 transports the feed to the spreading mechanism.

[0023] The material spreading mechanism 30 includes a spreading nozzle 31 and a blower 32. The spreading nozzle 31 has a feed inlet 311 that communicates with the discharge port of the cylindrical feeding outer pipe and two side-facing spreading nozzles 312. An air inlet 313 is also provided between the two spreading nozzles 312 of the spreading nozzle. The blower 32 is mounted on a movable trolley 11, and its output end is inserted into the air inlet 313.

[0024] Combination Figure 3As shown, in this embodiment, the dispensing nozzle 31 includes a first tee connector 33, two second tee connectors 34, a third tee connector 35, two dispensing pipes 36, two branch pipes 37, and two connecting pipes 38. The two branch pipes 37 are inclined, with their inlet ends connected to the two connectors of the first tee connector 33 respectively. The other connector of the first tee connector 36 forms an inlet 311 and communicates with the outlet of the cylindrical feeding outer pipe. The outlet ends of the two branch pipes 37 are connected to the two second tee connectors 34 respectively. The first connectors 341 of the two second tee connectors 34 are connected to one end of the dispensing pipe 36, the second connectors 342 inclined to the first connectors 341 are connected to the outlet of the corresponding branch pipe 37, and the third connectors 343 opposite to the first connectors 341 are connected to the corresponding connecting pipes 38. The other ends of the two dispensing pipes 36 form two dispensing nozzles 312 of the dispensing nozzle 31. The two connecting pipes 38 are connected together by a third tee connector 35. The third tee connector 35, which is perpendicular to the first and second connectors, forms an air inlet 313, and the output end of the fan 32 is inserted into the air inlet 313.

[0025] A control box 40 is fixed on the movable trolley 11. A controller is located inside the control box 40. The rotary motor 24, fan 32, 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 32, 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 the feed is thrown 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 32, and vibrator 25, thereby achieving scientific farming practices.

[0026] like Figure 1 and Figure 4 As shown, it also includes a pair of tracks 50 fixed to the pedestrian walkway. In this embodiment, the cross-section of the track is inverted V-shaped. The bottom surface of the movable trolley 11 is provided with two drive wheels 111 and two driven wheels 112. All wheels are engaged with their corresponding tracks. A drive motor 10 is fixed on the movable trolley 11. The drive motor 10 is electrically connected to the controller and the battery. The output end of the drive motor 10 is connected to the two drive wheels. With the above structure, only two tracks need to be laid on the pedestrian walkway of the shed. The movable trolley is placed on the two tracks, and the drive motor drives the drive wheels to rotate, driving the movable trolley 11 to move linearly along the track 50. Moreover, using tracks with an inverted V-shaped cross-section saves materials and reduces costs compared to square groove tracks.

[0027] In this embodiment, the drive wheel 111 is a nylon wheel, and the driven wheel 112 is a stainless steel wheel. Using nylon wheels reduces energy consumption and is inexpensive.

[0028] During operation, feed is mixed with water and then loaded into the feed cylinder 12. The drive motor 10 is then started, driving the drive wheel 111 to rotate, propelling the movable trolley 11 along the track 50 in a straight line. Simultaneously, the controller is activated using a remote control to start the rotary motor, vibrator, and fan. Feed flows from the lower outlet of the feed cylinder 12, through the storage bin, and into the cylindrical feeding outer pipe 22. Then, the rotation of the spiral spindle transports the feed to the downward-facing outlet of the cylindrical feeding outer pipe 22. The feed then falls freely into the spreading nozzle 31, and finally, the fan blows the feed into the water tank. When stopping is required, the controller is activated using the remote control to stop the rotary motor, vibrator, fan, and drive motor. When the movable trolley 11 needs to return, the drive motor is reversed, propelling the movable trolley 11 back along the track 50.

[0029] 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.
