Description

Technical Field

[0001] This invention relates to the field of aquaculture technology, and in particular to an automatic feed dispensing device. 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 of raising aquatic products from seedlings to finished products under artificial feeding and management. The aquatic products need to be fed at fixed intervals every day, and feeding is mainly done manually. Because the total amount of feed required is very large, it is very time-consuming and labor-intensive.

[0003] To improve feeding efficiency, automatic feed dispensing devices are currently used in aquaculture. When these devices deliver feed to the aquaculture area, the feed is released from the outlet of the device. This continuous release of feed to a single location in the aquaculture area causes the feed to concentrate in one spot, preventing it from being dispersed throughout the aquaculture area. This can lead to situations where there is too much feed in some areas and too little feed in others. Areas with too much feed tend to accumulate uneaten feed, polluting the water, while areas with insufficient feed result in uneven feeding and inconsistent growth rates among the fish, ultimately affecting the overall yield and quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of the existing technology where feed is continuously released from a single location in the aquaculture area, causing the feed to concentrate in a certain location in the aquaculture area, thus preventing the feed from being dispersed and scattered to the aquaculture area. Therefore, an automatic feed feeding device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Example 1: Refer to Figure 1-3 An automatic feed dispensing device includes a support frame 1. A storage bin 2 is fixedly connected to the upper end of the support frame 1. A first motor 3 is fixedly connected to the upper end of the storage bin 2. The output end of the first motor 3 extends into the storage bin 2 and is fixedly connected to a feeding screw 4 for dispensing feed. A second motor 5 is fixedly connected to the bottom end of the support frame 1. The output end of the second motor 5 passes through the support frame 1 and is fixedly connected to a support plate 6. Roller supports 7 are connected to both sides of the bottom end of the support plate 6. Each roller support 7 has a roller 11 connected to its bottom end. All wheels 11 are in rolling contact with the support frame 1. The upper end of the support plate 6 is fixedly connected to the housing 8. The upper end of the housing 8 is connected to the bottom end of the storage box 2. One side of the housing 8 is connected to the discharge rack 9. The upper ends of the support plate 6 are rotatably connected to the rotating shafts 10 on both sides. The bottom end of the support plate 6 is connected to the third motor 12 that drives the rotating shafts 10 to rotate. One end of each rotating shaft 10 extends into the housing 8 and is fixedly connected to the pusher blades 13 that push the feed out of the discharge rack 9. The storage box 2 is fixedly connected to the protective baffle 14 above the discharge rack 9.

[0030] Working principle:

[0031] When feeding, the controller controls the first motor 3 to be powered on and started. After the first motor 3 is started, it drives the extrusion screw 4 to rotate. After the extrusion screw 4 rotates, it squeezes and releases the feed from the bottom of the storage box 2. The extruded feed falls into the shell 8 under its own gravity.

[0032] The controller controls the two third motors 12 to be powered on and started. After each third motor 12 is started, it drives the rotating shaft 10 to rotate. Each rotating shaft 10 drives the pushing blade 13 to rotate. After the two pushing blades 13 rotate, the feed in the shell 8 is pushed out of the discharge rack 9 at an accelerated speed.

[0033] Simultaneously, the controller energizes and starts the second motor 5. After starting, the second motor 5 drives the support plate 6 to rotate left and right. The support plate 6 drives the roller support foot 7 to rotate. The roller support foot 7 makes rolling contact with the support frame 1 through the roller 11, so that the support plate 6 rotates smoothly, reducing vibration and wear. The support plate 6 also drives the shell 8 to rotate left and right. The shell 8 drives the discharge rack 9 to rotate left and right. When the two pusher blades 13 accelerate the feed in the shell 8 out of the discharge rack 9, the shell 8 is in a state of left and right rotation, so that the feed released from the discharge rack 9 is scattered in a fan shape, expanding the feeding range, avoiding local accumulation, improving the feeding uniformity, ensuring that the fish can get enough food, and promoting their uniform growth.

[0034] Example 2: After feed is fed from the discharge rack 9, the discharge rack 9 is in a conductive state. In humid weather, outside air passes through and enters the shell 8 through the discharge rack 9. Moisture adheres to the inner walls of the discharge rack 9 and the shell 8, thereby increasing the adhesion between the shell 8 and the inner walls of the discharge rack 9. This causes the feed to stick to the inner walls of the shell 8 and the discharge rack 9, resulting in the feed inside the shell 8 not being completely released. At the same time, the humid air inside the shell 8 can easily enter the storage tank 2, causing the feed inside the storage tank 2 to clump together. (Refer to...) Figure 5-7 As another preferred embodiment of the present invention, the difference from Embodiment 1 is that a smoothing mechanism 15 for reducing feed adhesion is connected to the housing 8. The smoothing mechanism 15 includes a perforated plate 151, which is fixedly connected to the upper end of the housing 8. A movable frame 152 is slidably connected to the perforated plate 151. An electric telescopic rod 153 for driving the movable frame 152 to move vertically is connected to the upper end of the perforated plate 151. A sealing plate 154 for sealing the discharge rack 9 is connected to the bottom end of the movable frame 152. A sealing ring 155 for improving the sealing effect is connected to the discharge rack 9. A plurality of first fixed tubes 156 are connected at equal intervals along the axial direction at the upper end of the housing 8. Each first fixed tube 156... Heating tubes 157 are connected to the interior of the housing 8. A circular baffle 158 is fixedly connected to the upper part of the interior of the housing 8. The circular baffle 158 is located below the heating tubes 157. A protective net 159 is fixedly connected to the inner ring wall of the circular baffle 158. The upper ends of the housing 8 are connected to the second fixed pipes 1510 on both sides. A mounting plate 1511 is fixedly connected to the movable frame 152. A connecting rod 1512 is fixedly connected to both sides of the bottom end of the mounting plate 1511. A movable block 1513 is fixedly connected to the bottom end of each connecting rod 1512. Each movable block 1513 is sealed and slidably connected to the corresponding second fixed pipe 1510. A one-way air vent valve 1514 is connected to the upper side of the housing 8.

[0035] Working principle:

[0036] When the feed inside the housing 8 is released from the discharge rack 9, the controller controls the electric telescopic rod 153 to be powered on and started. After the electric telescopic rod 153 is started, it drives the movable frame 152 to move downward a set distance. The movable frame 152 drives the sealing plate 154 to move downward a set distance to block and seal the discharge rack 9. The sealing ring 155 improves the sealing effect of the sealing plate 154 on the discharge rack 9.

[0037] Simultaneously, as the movable frame 152 moves downward, it also drives the mounting plate 1511 downward. The mounting plate 1511 drives the connecting rod 1512 downward, and the connecting rod 1512 drives the movable block 1513 downward. Since the discharge frame 9 is sealed by the sealing plate 154, some of the gas inside the housing 8 is released from the one-way vent valve 1514, reducing the amount of humid gas inside the housing 8. The controller then controls the heating element 157 to be energized and started. The heat generated after the heating element 157 is started enters the housing 8, and the circular baffle 158 and the anti-corrosion... After the protective net 159 is in place, it covers the bottom end of the first fixed tube 156 to prevent feed from entering the first fixed tube 156. The heat generated by heating dries the inner wall of the shell 8, improving the dryness of the inner wall of the shell 8 and the inner wall of the discharge rack 9, thereby reducing the adhesion between the inner wall of the shell 8 and the inner wall of the discharge rack 9. This prevents feed from sticking to the inner wall of the shell 8 and the inner wall of the discharge rack 9 when feeding feed next time, and allows the feed in the shell 8 to be completely discharged. At the same time, it reduces the entry of humid gas into the storage box 2 and reduces the clumping of feed in the storage box 2.

[0038] Example 3: When the sealing plate 154 moves downward to block and seal the discharge rack 9, the bottom end of the sealing plate 154 presses against the upper end of the outlet of the discharge rack 9. When the feed is released from the outlet of the discharge rack 9, the debris in the feed is easily left on the upper end of the outlet of the discharge rack 9. When the sealing plate 154 moves downward to block and seal the discharge rack 9, the debris left on the outlet of the discharge rack 9 affects the sealing effect of the sealing plate 154 on the discharge rack 9. (Refer to...) Figure 8-9As another preferred embodiment of the present invention, the difference from embodiment 2 is that the upper end of the perforated plate 151 is connected to an anti-obstruction mechanism 16 to improve the sealing effect between the perforated plate 151 and the discharge rack 9. The anti-obstruction mechanism 16 includes an extrusion plate 162, and a groove 161 is formed on one side of the sealing plate 154. The extrusion plate 162 is slidably connected to the groove 161, and a limit rod 163 is fixedly connected to the extrusion plate 162. One end of the limit rod 163 contacts the inner wall of the groove 161, and the extrusion plate 162 is fixedly connected to the limit rod 162. A spring 164 is fixedly connected to the groove 161. Several springs 164 are provided and are evenly distributed along the length of the extrusion plate 162. Several air holes 165 are evenly distributed along the length of the bottom of the groove 161. An air pump 166 is fixedly connected to the upper end of the perforated plate 151. An air outlet pipe 167 is connected to the outlet end of the air pump 166. A one-way conduit 168 is connected to the upper end of the groove 161. One end of the one-way conduit 168 is sealed and slidably inserted into the air outlet pipe 167.

[0039] Working principle:

[0040] When the electric telescopic rod 153 drives the movable frame 152 to move downward, the sealing plate 154 drives the one-way guide tube 168 to slide and seal on the air outlet pipe 167. At the same time, the controller controls the air pump 166 to start. After the air pump 166 starts, it draws in gas and guides the gas into the air outlet pipe 167. The gas in the air outlet pipe 167 is guided into the groove 161 through the one-way guide tube 168. The gas in the groove 161 is released from several air holes 165. The gas released from the air holes 165 blows away the feed debris remaining at the upper end of the outlet of the feed rack 9, so that the feed debris is separated from the upper end of the outlet of the feed rack 9, thus preventing the feed debris from affecting the sealing effect of the sealing plate 154 on the feed rack 9.

[0041] After the bottom end of the sealing plate 154 contacts the upper end of the outlet of the discharge rack 9, the upper end of the outlet of the discharge rack 9 will block and seal several air holes 165. At this time, the controller controls the air pump 166 to stop working, and the gas introduced into the groove 161 pushes the extrusion plate 162 outward. The extrusion plate 162 extrudes the outlet of the discharge rack 9, improving the sealing effect on the outlet of the discharge rack 9.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
