Description

Technical Field

[0001] The invention relates to a pond aquaculture feeding device, in particular to a pond aquaculture flowing water feeding device driven by a submersible pump, and belongs to the technical field of aquaculture. Background Art

[0002] Feeding in aquaculture is a key component that directly impacts aquaculture profitability. A reasonable feeding method can significantly improve feed utilization, promote the growth of aquaculture organisms, and reduce feed waste, residual feed pollution, and aquaculture costs. While traditional feeding equipment, such as mechanical spreading devices or pneumatic conveying, successfully achieves mechanized feeding, it also presents the following problems:

[0003] First, the high-speed movement and collision of bait can easily lead to an increase in the breakage rate; second, it is impossible to achieve uniform feeding, which can easily lead to local accumulation or sparse distribution of residual bait, affecting the water environment of the breeding pond and the feeding efficiency of the breeding organisms; third, the energy consumption is high.

[0004] Therefore, the existing technology also has related designs for underwater feeding. For example, a Chinese patent document with a publication date of April 28, 2023 and publication number CN116019044A discloses an aquaculture mixing feeding device and feeding method. It proposes the concept of underwater feeding, but there are still deficiencies in the control of the sufficiency and uniformity of the mixing of feed and water, as well as the distribution of feeding. Summary of the Invention

[0005] The present invention proposes a water feeding device driven by a submersible pump. The feed and water are initially mixed by a feed-water mixing and feeding mechanism, and then fully and evenly mixed by a mixing bin in a mixing and feeding unit. The submersible pump in the mixing and feeding unit provides negative pressure, pumping the feed upward to a combined feeding pipe above the water surface. Finally, the feed is delivered to the feeding point by positive pressure through distributed feed pipes on the combined feeding pipe, forming underwater distributed feeding. This device can effectively and evenly feed the fish, achieving a large amount of water + a small amount of feed during the feeding process, and can avoid pressure accumulation and even blockage caused by the gathering of feed at bends during underwater feeding.

[0006] The present invention adopts the following technical solutions:

[0007] A pond aquaculture flowing water feeding device driven by a submersible pump comprises a feed-water mixing and feeding machine 1, a mixing and feeding unit 2, and a combined feeding pipe 3; the feed-water mixing and feeding mechanism 1 is used to store feed and preliminarily mix the feed with flowing water and then transport it; the mixing and feeding mechanism 2 is located below the water surface and comprises, from bottom to top, a mixing bin 202, a submersible pump 201, and a float 203; the mixing bin 202 is connected to the conveying pipeline of the feed-water mixing and feeding mechanism 1, and the mixing bin 202 has pores connected to the surrounding water body; the submersible pump 201 is connected to the upper part of the mixing bin 202, and the feed and flowing water further mixed in the mixing bin 202 are pumped upward to the combined feeding pipe 3 by negative pressure; the combined feeding pipe 3 comprises a main feeding pipe 301, which is located above the water surface and extends horizontally, and is provided with a plurality of branch feeding pipes 303 extending downward to below the water surface.

[0008] Preferably, the mixing bin 202 has a discharge port 202-2 at the center of the upper portion thereof, which is connected to the submersible pump 201, and a feed port 202-1 is provided on the side of the discharge port 202-2 for connecting to the conveying pipeline of the material-water mixing and feeding mechanism 1.

[0009] Preferably, the inner bottom of the mixing bin 202 is a spherical structure.

[0010] Preferably, the mixing bin 202 has pores communicating with the surrounding water body, and is specifically configured as a grid-shaped water inlet trough on the side of the bin body, and the width of the water inlet trough is smaller than the outer diameter of the smallest unit of feed.

[0011] Preferably, each of the branch feed pipes 303 is provided with a feed valve 302 , and the feed valve 302 is also located above the water surface.

[0012] Furthermore, the main feed pipe 301 is a hard pipe, and the branch feed pipe 303 is a flexible pipe for delivering feed to the feeding location; the feeding valve 302 is used to control the feeding sequence of the branch feed pipe 303.

[0013] Furthermore, the main feed pipe 301, the branch feed pipe 303 and the feed valve 302 are modularly designed and can be increased, decreased or extended according to the actual aquaculture conditions in the water area.

[0014] Preferably, the main feed pipe 301 is mounted on a side wall or bank of the pond through a bracket or directly fixedly.

[0015] Furthermore, the discharge holes opened on the distribution pipe 303 are located on the same side of the distribution pipe 303; when the distribution pipe 303 is discharging under positive pressure, the discharge direction is as downward as possible or inclined downward, and the distribution pipe 303 is in a floating or suspended state, with its end pointing to the other side wall of the pond. The length of the distribution pipe 303 is selected according to the coverage range of the pond.

[0016] Furthermore, the end of the feed delivery pipe 303 has an openable and closable structure for cleaning residual feed.

[0017] The beneficial effects of the present invention are:

[0018] 1) Since the feed sinks slowly during the first mixing, local blockage at the bend of the pipeline is easily caused by the low uniformity of the mixing of feed and water during underwater feeding. The present invention adopts a two-stage feed mixing method. In particular, the second stage also uses open water (mixing of gaps with external water) in the mixing and feeding unit 2 to enhance the uniformity of the mixing of feed and water, thereby achieving a large amount of water + a small amount of feed in the feeding process. On the basis of improving feeding efficiency and utilization rate, it can also avoid the pressure accumulation and even blockage caused by the aggregation of bait at the bend during underwater feeding.

[0019] 2) A single submersible pump is used as the power source to transport the water-material mixture to the feeding point through a pipeline. The power source is simple and reliable;

[0020] 3) Through the distributed piping layout and the floating or suspended state of the feed pipes caused by the reaction force of the water flow, it is possible to achieve full pond coverage of bait feeding. The piping can also be arranged according to the living habits of the cultured organisms, making feeding more precise;

[0021] 4) Bait is transported through pipe water flow, which not only allows precise feeding of bait, but also promotes the flow and circulation of aquaculture water;

[0022] 5) The submersible pump is cleverly used to provide a short upward lift, so that the combined feed pipe is located above the water surface, making maintenance and valve control easier.

[0023] 6) The modular conveying pipe is mainly composed of standardized components and pipes, which is conducive to expansion or node selection according to needs and is also easy to maintain. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] See Figure 1 , a pond aquaculture water feeding device driven by a submersible pump, comprising: a material-water mixing mechanism 1, four pillars are installed at the four corners of the bottom plate of the material-water mixing mechanism 1 as the main body support, a plastic shell is covered on the outside of the box, inside the box, the upper extension part of the hopper is installed with the pillars, a feeding hole is opened at the bottom, and a hopper door with a short slot limit is installed below the feeding hole, the feeding plate is installed obliquely below the hopper door, the larger end of the funnel is provided with a ring-shaped water outlet pipe, the feeding pipe is a flexible pipe, one end of which is inserted into the water outlet below the funnel, and the feeding water pump and the controller are installed in the box and fixed on the bottom plate; the function that the material-water mixing mechanism 1 needs to realize is the preliminary mixing of feed and water. This part of the content is not the focus of the present invention, and it can be understood that it can be realized.

[0033] Figure 2 The external structure of the mixing and feeding unit 2 is shown. The feed port of the mixing bin 202 is inserted into one end of the feed pipe of the material-water mixing mechanism 1 and fastened with a clamp. The discharge port and the water inlet end of the submersible pump 201 are installed with screws and nuts. A grid-shaped water inlet trough is provided on the side of the mixing bin 202; a feed port and a discharge port are provided on the top of the bin. The lower half of the mixing bin 202 is hemispherical. The above-mentioned mixing bin 202 is divided into upper and lower structures. The two parts are installed by interference fit of pins. The upper part includes the feed port, the discharge port, and the water inlet trough, and the lower part is a hemispherical bottom. A threaded nut is provided at one end of the water outlet of the submersible pump 201. The water outlet of the submersible pump 201 is inserted into the center of the float 203 and the nut is tightened for installation.

[0034] Figure 3The structure of the combined feed pipe 3 is shown. The submersible pump outlet is screwed to the main feed pipe 301. The other end is extended by installing the main feed pipe 301 according to actual needs. The two sections of the main feed pipe 301 are connected by a water pipe connector. The end of the combined feed pipe 3 is connected by a funnel-shaped tube and equipped with a feed valve 302 and a branch feed pipe 303. The branch feed pipe 303 has evenly spaced discharge holes on one side. The feed valve 302 is a solenoid valve. All wires along the main feed pipe are waterproofed. When the entire device is in operation, the branch feed pipe 303 is suspended in the water or floats on the water surface. The feeding direction is as downward as possible. Since the branch feed pipe 303 is a flexible tube, it may also be in a state of continuous twisting.

[0035] like Figure 2 and 5 As shown, the mixing and feeding unit 2 needs to be placed in the water and rely on the float 203 to achieve a floating state; the above-mentioned main feed pipe 301 can be installed on the shore or erected on the water surface as shown in the figure; when installing the above-mentioned branch feed pipe 303, the discharge hole needs to be set along the direction of the bottom of the water.

[0036] Working principle:

[0037] See Figure 5 As shown, the feed-water mixing mechanism is installed on the shore of the target water area. After the device is started, the feed-water mixing mechanism 1 pumps water from the working water area and mixes the pumped water with the feed stored in the feed-water mixing mechanism 1. After the feed is preliminarily mixed, it is transported to the mixing and feeding unit 2 through the feeding pipe. Under the action of gravity, the feed is finally accumulated at the hemispherical bottom of the mixing bin 202. After a period of time, the submersible pump works and uses the submersible pump 201 to transport the feed in the mixing bin 202 to the combined feeding pipe 3. At this time, the feed and water are finally mixed. The feed passes through the main feeding pipe under the action of the submersible pump 201; the feeding valve 302 installed on the main feeding pipe 301 is opened according to the control demand, and the feed enters the branch feeding pipe 303 under the action of the water flow, and is finally discharged from the discharge hole on the branch feeding pipe 303. The feeding is completed, and the device as a whole stops feeding the feed and continues to pump water to flush the pipeline to empty the residual feed in the pipeline.

[0038] The present invention is divided into two-stage feed mixing. Since the existing technology adopts one-time feed mixing, the feed sinks slowly, so it is easy to cause local blockage at the bend of the pipeline due to the low mixing uniformity of feed and water during underwater feeding. The present invention adopts two-stage feed mixing, especially the second stage in the mixing and feeding unit 2 also uses open water (mixing of gaps with external water) to enhance the uniformity of feed and water mixing, thereby achieving a large amount of water + a small amount of feed in the feeding process. On the basis of improving feeding efficiency and utilization rate, it can also avoid the pressure accumulation and even blockage caused by the convergence of bait at the bend during underwater feeding; a single submersible pump is used as the power The water-feed mixture is transported to the feeding point through a pipeline, and the power source is simple and reliable. Through the distributed pipeline layout and the floating or suspended state of the distribution pipe caused by the reaction force of the water flow, the whole pond can be covered with bait for feeding, and the pipeline can be arranged according to the living habits of the cultured organisms, so that the feeding is more accurate. The bait is transported by the water flow in the pipeline, which not only can accurately feed the bait at a fixed point, but also can promote the flow and circulation of the aquaculture water. The clever use of the submersible pump to increase the lift of the small distance can realize that the combined feeding pipe is located above the water surface as a whole, which is convenient for maintenance and valve control. The combined delivery pipe is mainly composed of standardized components and pipelines, which is conducive to expansion or node selection according to needs, and is also convenient for maintenance.

[0039] The above are preferred embodiments of the present invention. Those skilled in the art may make various changes or improvements based on the above. Without departing from the overall concept of the present invention, these changes or improvements should fall within the scope of protection claimed by the present invention.
