Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture equipment, in particular to a water pressure feeder. Background Art

[0002] At present, the feeders used in aquaculture ponds for feeding bait are mostly dial feeders and spiral feeders. The main working part of the dial feeder is the dial, which is usually a rotating disk with multiple evenly distributed paddles, which rotates under the drive of the reduction motor to achieve the purpose of feeding. The spiral shaft of the spiral feeder is the core component of the spiral feeder, on which spiral blades are installed. The spiral blades are arranged at a certain pitch. When the spiral shaft rotates, the blades push the material forward.

[0003] However, the adaptability of dial feeders is limited, and they often have specific requirements for material properties and working environments. Dial feeders cannot effectively adapt to baits with particles smaller than 1 mm or larger than 15 mm, baits mixed with animal health products, block or powdered baits, etc. When conveying compliant baits, dial feeders are also prone to blockage, sticking, and accumulation of materials, and need to be cleaned regularly to avoid mold and odor. During the conveying process of spiral feeders, the friction between the spiral blades and the feed trough and the mutual squeezing of the bait itself can easily cause the granular bait to break, so it is not suitable for breeding sites that require the integrity of the feeding to be maintained. Spiral feeders also have problems with bait blockage or impact, especially when conveying at high speed or processing highly viscous baits. In severe cases, the machine may get stuck, and the inside of the spiral feeder is not easy to clean, and the maintenance cost is high. Utility Model Content

[0058] In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides examples of various specific processes and materials, but those skilled in the art can recognize the application of other processes and / or the use of other materials.

[0059] Figures 1 to 15 The utility model shows a hydraulic feeder, which comprises a pressure plate assembly and a rotating disk.

[0060] The pressing plate assembly includes a first pressing plate 11a and a second pressing plate 11b which are arranged opposite to each other and connected to each other, and the pressing plate assembly is provided with a feed inlet 101, a water inlet 102, a mixing outlet 103 and a drain outlet 104. The feed inlet 101 is arranged on the first pressing plate 11a or the second pressing plate 11b, the drain outlet 104 is arranged on the first pressing plate 11a or the second pressing plate 11b, one of the water inlet 102 and the mixing outlet 103 is arranged on the first pressing plate 11a, and the other is arranged on the second pressing plate 11b.

[0061] At least five chambers 21 are formed on the turntable 2. The at least five chambers 21 are distributed in the circumferential direction, surround the rotation axis of the turntable 2, and are spaced apart from each other. Each chamber 21 passes through two opposite surfaces of the turntable 2 respectively.

[0062] The turntable 2 is disposed between the first pressing plate 11a and the second pressing plate 11b, and the first pressing plate 11a and the second pressing plate 11b are respectively slidably pressed against two opposite surfaces of the turntable 2 to close each chamber 21. The water inlet 102 and the mixing outlet 103 form a hydraulic channel that can simultaneously communicate with the same chamber 21. The water inlet 102 and the mixing outlet 103 can be mutually offset in the axial direction of the turntable 2, or the projections of the water inlet 102 and the mixing outlet 103 in the axial direction of the turntable 2 can at least partially overlap.

[0063] The turntable 2 is configured to rotate around its own axis under the driving action of external force, so that each chamber 21 is sequentially and cyclically connected to the feed port 101, the hydraulic channel and the drain port 104. When the turntable 2 rotates, the hydraulic channel formed by the water inlet 102 and the mixing outlet 103 is connected to the same chamber 21 at the same time.

[0064] The feed port 101 is used to feed the material to be transported, and the water inlet 102 is used to connect the high-pressure water source. When in use, the turntable 2 is driven by an external force to rotate between the first pressing plate 11a and the second pressing plate 11b, and the material is fed into the corresponding chamber 21 through the feed port 101, and the high-pressure water flow is fed into the corresponding chamber 21 through the water inlet 102.

[0065] After the chamber 21 of the turntable 1 conveys the material through the feed port 101, the material is pushed and rotated to the position of the water pressure channel, connected with the water inlet 102 and the mixing outlet 103, and the water inlet 102 conveys high-pressure water flow into the chamber 21, and the high-pressure water flow sends the material in the chamber 21 out through the mixing outlet 103, thereby realizing the conveying of the material.

[0066] The turntable 2 continues to rotate, and the chamber 21 rotates to the position of the drain port 104 after passing through the water pressure channel. The remaining water in the chamber 21 can be discharged through the drain port 104 to relieve pressure.

[0067] The chamber 21 passes through the feed port 101, the hydraulic channel and the drain port 104 in sequence to complete a working cycle. After the pressure is released through the drain port 104, the chamber 21 continues to rotate and reaches the position of the feed port 101 again to enter the next working cycle.

[0068] The hydraulic feeder provided by the utility model is used to deliver bait to aquaculture ponds. Compared with traditional dial feeders and spiral feeders, the hydraulic feeder of the utility model uses high-pressure water flow to provide power to deliver bait, which is not prone to blockage and accumulation of materials, and will not cause the bait to break due to squeezing the bait. It can keep the bait particles intact, can deliver large-particle bait and bait with greater viscosity, and has wider adaptability. In actual use, it is necessary to select a high-pressure water source with appropriate pressure and flow to provide a water flow with rated flow and rated pressure to the water inlet 102. By adjusting the water pressure and flow, the delivery speed of the bait can be accurately controlled to avoid excessive impact causing the bait to break.

[0069] In addition, the hydraulic feeder has a self-cleaning effect. The high-pressure water flow can clean the inside of the hydraulic feeder while transporting the bait, preventing the bait from accumulating for a long time inside the hydraulic feeder, which would cause mold and odor. It does not require time and manpower to disassemble and clean it frequently, thus reducing maintenance costs.

[0070] In a preferred embodiment, the projections of the water inlet 102 and the mixing outlet 103 in the axial direction of the turntable 2 at least partially overlap, which can reduce the resistance to the high-pressure water flow, allowing the water flow to smoothly transport materials and ensure work efficiency.

[0071] In a preferred embodiment, the two opposite sides of the turntable 2 are both planes and are respectively perpendicular to the axis of the turntable 2. The turntable 2 is set in a disc shape, and the chambers 21 are evenly distributed in the circumferential direction of the turntable 2 to form a fan-shaped structure, and the chambers 21 have the same shape and size.

[0072] In order to make the hydraulic feeder feed and drain smoothly, the turntable 2 can be used in an upright position with the axis, and the two opposite surfaces of the turntable 2 are the top surface and the bottom surface respectively. The first pressing plate 11a is against the top surface of the turntable 2, and the second pressing plate 11b is against the bottom surface of the turntable 2. The feed port 101 is set on the first pressing plate 11a, and the material can fall from the top feed port 101 into the chamber 21 below under the action of gravity. The drain port 104 is set on the second pressing plate 11b, and the water in the chamber 21 can be discharged through the drain port 104 at the bottom under the action of gravity.

[0073] The drain port 104 is used to connect to a drainage pipe to drain excess water through the drainage pipe. However, when the drain port 104 is directly connected to the drainage pipe, the drainage speed is slow and the pressure relief effect cannot meet the requirements.

[0074] like Figure 1 and Figure 5 As shown, in order to improve the drainage speed and pressure relief effect of the drain outlet 104, the drain outlet 104 is further connected to an overflow funnel 3, and an overflow port 31 is provided at the bottom of the overflow funnel 3, and the overflow port 31 can be connected to a drainage pipe.

[0075] In detail, the top of the overflow funnel 3 is open and connected to the external environment to balance the pressure. The position of the drain port 104 is higher than the overflow port 31 and lower than the opening at the top of the overflow funnel 3.

[0076] During the process of the chamber 21 rotating from the water pressure channel to the drain port 104, the internal water pressure is relatively high. After being connected with the drain port 104, the high-pressure water in the chamber 21 can quickly enter the overflow funnel 3 from the drain port 104, and then be discharged through the overflow port 31. The overflow funnel 3 can temporarily store a certain amount of water flow to ensure that the drain port 104 maintains a relatively high drainage speed.

[0077] like Figure 5 In the specific embodiment shown, the bottom of the overflow funnel 3 is connected to a water diversion pipe 32, which extends transversely to the bottom of the drain port 104, and the water diversion pipe 32 is provided with a water inlet 321 that docks with the drain port 104. The water discharged from the drain port 104 enters the overflow funnel 3 through the water diversion pipe 32, and then is discharged from the overflow port 31.

[0078] In some embodiments, Figure 1 , Figure 2 and Figure 4 As shown, the outside of the pressing plate assembly is connected with a feed pipe 15, a water inlet pipe 16 and a discharge pipe 17. The feed pipe 15 is connected to the feed port 101 for feeding materials into the feed port 101; the water inlet pipe 16 is connected to the water inlet 102 for connecting to a high-pressure water source and delivering high-pressure water flow to the water inlet 102; the discharge pipe 17 is connected to the mixing outlet 103 for outputting the mixed high-pressure water flow and materials.

[0079] The specific connection methods of the feed pipe 15, the water inlet pipe 16 and the discharge pipe 17 to the pressure plate assembly include but are not limited to welding, bonding, integral molding and screw connection, etc. This article does not make any limitation on this. It should be noted that the water inlet pipe 16 and the discharge pipe 17 need to be sealed with the pressure plate assembly to avoid water leakage.

[0080] like Figure 2 and Figure 8 As shown, the first pressing plate 11a and the second pressing plate 11b can be fixedly connected by a bolt assembly 13, and multiple groups of bolt assemblies 13 are close to the edges of the first pressing plate 11a and the second pressing plate 11b and are distributed at intervals. Multiple groups of bolt assemblies 13 surround the rotating disk 2, and there is a gap between the rotating disk 2. Multiple groups of bolt assemblies 13 enable the first pressing plate 11a and the second pressing plate 11b to press the rotating disk 2 with appropriate pressure, and fit tightly, and the structure is reliable and stable, which can ensure the quality of use.

[0081] Furthermore, if Figure 6 , Figure 7 and Fig. 9 As shown, a side plate 12 surrounding the turntable 2 can be arranged between the first pressing plate 11a and the second pressing plate 11b. The side plate 12 is attached to or connected with the first pressing plate 11a and the second pressing plate 11b. The side plate 12 can protect the turntable 2 rotating inside to prevent the turntable 2 from being disturbed or hurting people when rotating.

[0082] The side plate 12 can be a rectangular plate with two ends butted together. The rectangular plate is formed into a cylindrical shape and abuts against the edges of the first pressing plate 11 a and the second pressing plate 11 b . The two butted ends of the side plate 12 are connected by a lock 14 .

[0083] Specifically, an installation gap is left between the side plate 12 and the side wall of the turntable 2. The first pressing plate 11a and the second pressing plate 1b are fixedly connected by bolt assemblies 13, and multiple groups of bolt assemblies 13 pass through the installation gap between the side plate 12 and the turntable 2.

[0084] The connection structure between the first pressing plate 11a, the second pressing plate 11b and the side plate 12 is simple, easy to assemble and disassemble, and convenient for inspection and maintenance.

[0085] The turntable 2 and the first pressing plate 11a and the second pressing plate 11b need to be sealed to prevent water leakage in the chamber 21. Figure 4 As shown, the two opposite sides of the rotating disk 2 are respectively provided with sealing rings 4 surrounding the edges of each chamber 21, and the sealing rings 4 are slidably sealed with the corresponding first pressing plate 11a or second pressing plate 11b. The sealing rings 4 are fixed on the two opposite sides of the rotating disk 2, and the first pressing plate 11a and the second pressing plate 11b respectively press the sealing rings to seal the edges of each chamber 21.

[0086] In one embodiment, the sealing ring 4 can be an O-ring, which can surround the edge of the chamber 21. The number of O-rings is twice the number of chambers 21, and the top edge of each chamber 21 is sealed with the first pressing plate 11a by an O-ring, and the bottom edge of each chamber 21 is sealed with the second pressing plate 11b by an O-ring.

[0087] In another embodiment, if Figure 2 and Fig.11 As shown, two sealing rings 4 are provided, and both sealing rings 4 are integral structures and have the same structure. One sealing ring 4 is arranged between the rotating disk 2 and the first pressing plate 11a, and the other sealing ring 4 is arranged between the rotating disk 2 and the second pressing plate 11b.

[0088] Specifically, the sealing ring 4 includes an outer ring 41, an inner ring 42 and a plurality of connecting edges 43, and the plurality of connecting edges 43 are connected at intervals between the outer ring 41 and the inner ring 42. A plurality of chambers 21 are located between the outer ring 41 and the inner ring 42 of the sealing ring, and the connecting edges 43 are located between adjacent chambers 21, and can surround the edges of each chamber 21 to isolate each chamber 21 from each other.

[0089] like Fig.10 and Fig.11 As shown, grooves 22 for embedding the sealing ring 4 are respectively formed on the top surface and the bottom surface of the rotating disk 2. The shape of the grooves 22 is adapted to the shape of the sealing ring 4, so as to fix the sealing ring 4.

[0090] like Fig.10 As shown, each chamber 21 is configured to be able to rotate to an axial projection area to cover the feed port 101 or the water pressure channel or the drain port 104, respectively, and the structure is reasonable and compact.

[0091] Furthermore, if Fig.12 As shown, in the rotation direction of the turntable 2, the distance from the feed inlet 101 to the mixing outlet 103 is less than or equal to the distance from the feed inlet 101 to the water inlet 102. After the chamber 21 leaves the feed inlet 101, it is connected to the water inlet 102 and the mixing outlet 103 at the same time, or connected to the mixing outlet 103 and the water inlet 102 in sequence.

[0092] In one embodiment, the area of ​​the water inlet 102 is smaller than the area of ​​the mixing outlet 103 to prevent the water flow and material pressure discharged from the mixing outlet 103 from being too high.

[0093] In one embodiment, the projection of the mixing outlet 103 in the axial direction of the rotating disk 2 covers the water inlet 102, which is conducive to the smooth transportation of materials by the high-pressure water flow and makes the rotating disk 2 more compact.

[0094] In some embodiments, Fig.12 and Fig.13 As shown, with the center of the turntable 2 as the center of the circle, the axis passes through the center of the circle. In the circumferential direction of the turntable 2, the angle of the maximum center angle corresponding to each chamber 21 is α, the angle of the minimum center angle between the edge of the feed port 101 and the edge of the water pressure channel is β, β is greater than or equal to α, the angle of the minimum center angle between the edge of the water pressure channel and the edge of the drain port 104 is γ, γ is greater than or equal to α; the angle of the minimum center angle between the edge of the drain port 104 and the edge of the feed port 101 is θ, θ is greater than or equal to α.

[0095] The distance between the feed port 101 and the hydraulic channel is at least the distance of a chamber 21, the distance between the hydraulic channel and the drain port 104 is at least the distance of a chamber 21, and the distance between the drain port 104 and the feed port 101 is at least the distance of a chamber 21. When the turntable 2 rotates, the hydraulic channel is completely separated from the feed port 101 and the drain port 104 on the left and right sides, maintaining the water flow pressure in the hydraulic channel and the corresponding chamber 21. The feed port 101 and the drain port 104 are also completely separated and do not affect each other.

[0096] like Fig.12 and Fig.13 In a specific embodiment shown, five chambers 21 are formed on the turntable 2, and the central angle α of the five chambers 21 is less than 72°. The angle β between the feed port 101 and the water pressure channel is greater than or equal to 72°, the angle γ between the water pressure channel and the drain port 104 is greater than or equal to 72°, and the angle θ between the drain port 104 and the feed port 101 is greater than or equal to 72°.

[0097] like Fig.14 In a specific embodiment shown, six chambers 21 are formed on the turntable 2, and the central angle α of the six chambers 21 is less than 60°. The angle β between the feed port 101 and the water pressure channel is greater than or equal to 60°, the angle γ between the water pressure channel and the drain port 104 is greater than or equal to 60°, and the angle θ between the drain port 104 and the feed port 101 is greater than or equal to 60°.

[0098] like Fig.15 In a specific embodiment shown, eight chambers 21 are formed on the turntable 2, and the central angle α of the eight chambers 21 is less than 45°. The angle β between the feed port 101 and the water pressure channel is greater than or equal to 45°, the angle γ between the water pressure channel and the drain port 104 is greater than or equal to 45°, and the angle θ between the drain port 104 and the feed port 101 is greater than or equal to 45°.

[0099] Those skilled in the art can adaptively set the size and shape of the feed port 101 , the water inlet 102 , the mixing outlet 103 , and the drain port 104 according to actual requirements for material conveying efficiency and the number of chambers 21 .
