Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, and more specifically, relates to a feeding mechanism. Background Technology

[0002] Aquaculture is a production activity involving the breeding, cultivation, and harvesting of aquatic plants and animals under human control. It generally includes the entire process from seedling to marketable aquatic products under artificial feeding and management. Aquaculture methods include extensive farming, intensive farming, and high-density intensive farming. High-density intensive farming utilizes methods such as flowing water, temperature control, aeration, and feeding high-quality feed to achieve high yields in small bodies of water, such as high-density fish and shrimp farming in flowing water. To improve the convenience of farming, most farmers equip their farms with feeding equipment for timed feeding, reducing manual labor.

[0003] Currently, existing feeding mechanisms generally use a motor-driven turntable or wheel to intermittently feed feed into an air duct. High-speed airflow then throws the feed outwards, causing it to spill into the water. However, these existing mechanisms are bulky, prone to clogging, and inconvenient to maintain. Furthermore, the high-speed rotation of the motor makes it difficult to accurately judge the amount of feed being fed from the turntable or wheel, making them suitable only for extensive feed dispensing methods. Therefore, a compact feeding mechanism with a small footprint is needed. Utility Model Content

[0032] The following disclosure provides many different implementation methods or examples for different solutions to implement this utility model.

[0033] Reference Figures 1 to 5 As shown, the feeding mechanism includes:

[0034] The housing 11 has a feeding channel inside, which has a receiving position, a discharging position, and a first channel 22 located between the receiving position and the discharging position.

[0035] Material discharge port 14 is provided on the housing 11 and located above the material receiving position;

[0036] The discharge port 15 is disposed on the housing 11 and located below the discharge position;

[0037] Feeding air duct 21 is provided on the housing 11. The discharge port 15 is connected to the feeding air duct 21. One end of the feeding air duct 21 is provided with a feeding port 23, and the other end of the feeding air duct 21 is provided with a fan 17.

[0038] Piston 10 is provided with a receiving chamber 101. Piston 10 can reciprocate linearly between a receiving position and a discharging position on the feeding channel, so that the receiving chamber 101 receives material at the receiving position and discharges the material in the receiving chamber 101 through the discharge port 15 to the feeding air duct 21 at the discharging position. The feeding air duct 21 can be connected to an external air source or to an air source inside the housing 11.

[0039] Under the action of the driving device, the piston 10 positions the receiving chamber 101 in the receiving position and the discharge port 14 above the receiving chamber 101. Material in the hopper, such as feed, falls into the receiving chamber 101 under gravity. After the piston 10 remains in the receiving position for a certain period, the driving device moves the piston 10, causing the receiving chamber 101 to move from the receiving position to the discharge position. During this process, the piston 10 cuts off the connection between the receiving position and the discharge position. After the receiving chamber 101 begins to enter the discharge position, the material in the receiving chamber 101 falls into the feeding channel. The material entering the feeding air duct 21 is blown out of the feeding port 23 by the airflow, causing the material to spill into the water. After the piston 10 moves into position, it remains in the discharge position for a certain period, allowing the material in the receiving chamber 101 to fall primarily into the feeding air duct 21. The piston 10 moves linearly from the unloading position to the left to the dropping position, where the receiving chamber 101 continues to receive material before sending it back to the unloading position. This linear reciprocating movement of the piston 10 achieves the functions of receiving and unloading material. The driving device can be a linear motor, cylinder, etc.

[0040] Preferably, the piston 10 is made of graphite nylon. Graphite nylon has a certain degree of oiliness, which gives the piston 10 excellent properties such as wear resistance and self-lubrication.

[0041] In one embodiment of this utility model, the piston 10 includes a first sidewall 103, a second sidewall 102, and a connecting post 104 connecting the first sidewall 103 and the second sidewall 102. A receiving cavity 101 is formed between the outer surfaces of the first sidewall 103, the second sidewall 102, and the connecting post 104. The piston 10 has a simple structure and is easy to manufacture. During movement, the first sidewall 103 and the second sidewall 102 respectively form a seal with the inner wall of the first channel 22 to prevent air from the feeding air duct 21 from entering the discharge port 14.

[0042] In one embodiment of this utility model, the length of the connecting column 104 is less than the length of the first channel 22. Specifically, when the piston 10 moves from the material dropping position to the material receiving position, the second side wall 102 and the first channel 22 form a seal. When the first side wall 103 and the first channel 22 form a seal, the material dropping port 14 and the material receiving chamber 101 are disconnected, and the material dropping port 15 and the material receiving chamber 101 are also not connected. When the piston 10 continues to move to the right, the material dropping port 15 and the material receiving chamber 101 are connected, and the material in the material receiving chamber 101 falls into the feeding channel. The material entering the feeding air duct 21 is blown out of the feeding port 23 and thrown outward under the action of the wind. When the piston 10 moves to the right to the maximum stroke, the first side wall 103 and the first channel 22 are still in a sealed state to prevent the wind from flowing back into the material dropping port 14.

[0043] In one specific embodiment, the length of the connecting column 104 is equal to or greater than the width of the discharge port 14 so that the material can smoothly fill the receiving cavity 101; the length of the connecting column 104 is equal to or less than the width of the discharge port 15 so that all the material in the receiving cavity 101 can enter the air supply channel through the discharge port 15.

[0044] The feeding channel is shaped like an "8" near the discharge port 15. Specifically, the inner diameter of the end near the discharge port 15 is larger than the inner diameter of the side away from the discharge port 15, which facilitates the gathering of air and the throwing of materials.

[0045] In one embodiment of this utility model, a piston sleeve 16 is installed inside the feeding channel. The piston sleeve 16 is provided with a first notch 161 corresponding to the discharge port 14 and a second notch 162 corresponding to the discharge port 15. The piston 10 reciprocates inside the piston sleeve 16. Preferably, the piston sleeve 16 is made of stainless steel. After the piston sleeve 16 is installed in the feeding channel, the first channel 22 is located inside the piston sleeve 16.

[0046] In one embodiment of this utility model, a fan mounting cavity and an air inlet cavity are provided on the side of the housing 11 away from the feed port 23. The fan 17 is disposed in the fan mounting cavity, and the side wall of the air inlet cavity is provided with multiple air inlet holes 13. A material level sensor is disposed on the side of the fan near the feed duct 21. The fan 17 is a high-speed fan. After the material level sensor senses material, the fan starts and throws the material out of the air delivery duct.

[0047] In one embodiment of this utility model, the piston 10 is mounted on a linear motor, which drives the piston 10 to move in a straight line. A limiting block is provided on the outer side of the end face of the piston 10 exposed outside the housing 11. When the end face of the piston 10 is in direct or indirect contact with the limiting block, the receiving cavity 101 is located below the discharge port 14. The linear motor can be mounted on the outside of the housing 11.

[0048] In one embodiment of this utility model, a vibration motor 18 and a material shortage sensor 20 are respectively provided on both sides of the discharge port 14. The vibration motor 18 is located on the side away from the discharge position, and the material shortage sensor 20 is located on the side closer to the discharge position. When the receiving chamber 101 is in the receiving position, the material from the discharge port 14 falls into the receiving chamber 101. When the material shortage sensor 20 senses that the material in the discharge port 14 is insufficient, the vibration motor 18 operates, causing the material in the hopper to fall into the discharge port 14 through vibration.

[0049] Of course, when the receiving chamber 101 is in the unloading position, the vibration motor 18 can also work. The vibration of the vibration motor 18 is transmitted to the receiving chamber 101 through the housing 11 so that the material in the receiving chamber 101 can fall into the feeding air duct 21 as soon as possible.

[0050] In one embodiment of this utility model, the housing 11 includes a first housing 111 and a second housing 112. The first housing 111 and the second housing 112 are respectively provided with cavities. After the first housing 111 and the second housing 112 are installed, the cavities on the first housing 111 and the second housing 112 form a housing 11 with a feeding channel, a discharge port 14, a discharge port 15, and a feeding air duct 21. The split structure of the housing 11 facilitates the installation of the piston 10, the piston sleeve 16, and the sensor, and also facilitates subsequent equipment maintenance. The first housing 111 and the second housing 112 can be connected and fixed by bolts or screws, or by snap-fit ​​connections.

[0051] The feeding method based on the feeding mechanism includes the following steps:

[0052] 1) The piston 10 moves to the receiving position, so that the receiving chamber 101 is opposite to the discharge port 14. The vibration motor 18 works and vibrates to drop the material into the receiving chamber 101 so that the receiving chamber 101 can receive the material from the discharge port 14.

[0053] 2) The piston 10 moves from the receiving position to the right along a straight line to the discharging position, so that the receiving chamber 101 is opposite to the discharging port 15, so that the material in the receiving chamber 101 falls from the discharging port 15 into the feeding air duct 21.

[0054] 3) When the fan is working, it generates high-speed wind. The high-speed wind blows the material that has entered the feeding duct 21 out of the feeding port 23 and throws it outward, so that the material falls into the water.

[0055] 4) After the material in the receiving chamber 101 has finished falling, the piston 10 moves from the material feeding position to the left along a straight line to the material feeding position, and the receiving chamber 101 continues to receive material.

[0056] In this invention, by recording the number of times the piston 10 moves, and by calculating the amount of material fed into the receiving chamber 101 each time based on the number of moves and the amount of material received each time, a more accurate material feeding is achieved.
