Description

Technical Field

[0001] This application relates to the field of aquaculture, and in particular to a non-powered rotary nozzle for shrimp feed. Background Technology

[0002] In the shrimp farming industry, uniform and efficient feeding is crucial for ensuring consistent shrimp growth and maximizing yield. The feed dispensing nozzle, a key piece of equipment in this process, directly determines feeding quality and farming efficiency. Currently, widely used feed dispensing nozzles operate on a "motor-driven rotation" model. The motor rotates the nozzle, generating centrifugal force to distribute the feed in a circular pattern into the shrimp pond. Simultaneously, the dispensing radius is controlled by adjusting the motor speed—higher motor speeds result in faster nozzle rotation, greater centrifugal force, and a larger dispensing radius; conversely, lower motor speeds reduce the dispensing radius, adapting to the needs of open-air shrimp ponds of varying sizes (smaller ponds require smaller radii, larger ponds require larger radii) and shrimp at different growth stages (juvenile shrimp require close-range feeding, adult shrimp require long-range feeding). Since shrimp ponds are all open-air environments, the nozzles and the matching feed-spreading motors need to be exposed to the outdoors for a long time, and must continuously endure rain, dust accumulation in the air, and the adhesion and corrosion of oil components in the shrimp feed. The operating environment of the equipment is quite harsh.

[0003] To meet the needs of adjusting the spreading radius and rotating spreading, the core solution of existing technology is to configure a separate spreading motor for the nozzle. The motor is directly connected to the nozzle through a coupling or gear structure, and the rotation of the motor output shaft drives the entire nozzle to rotate. At the same time, a motor controller is provided to change the speed by adjusting the input current or voltage of the motor, thereby realizing the control of the spreading radius.

[0004] However, existing technical solutions have many insurmountable defects, which seriously restrict the reliability, adaptability to different scenarios, and economic efficiency of the nozzles.

[0005] First, as a core driving component, the feed-spreading motor is susceptible to corrosion from rainwater, dust, and grease in open-air environments. Rainwater seeping into the motor can cause short circuits, dust accumulation can accelerate the wear of motor bearings, and grease buildup can affect motor heat dissipation. The combined effect of these three factors leads to frequent motor failures, which in turn can cause the nozzles to jam or even stop, interrupting the feeding process. This not only affects shrimp feeding but also requires frequent repairs or replacements of the motor, increasing farming costs.

[0006] Secondly, the extra weight of the motor significantly increases the load-bearing capacity of the feed distribution pipe. When the nozzle rotates, the center of gravity shifts, which can easily cause a pendulum effect, resulting in the feeding trajectory deviating from the preset range. This leads to a significant decrease in feeding uniformity, with some areas having piled-up shrimp feed and others having no feed, causing competition among shrimp for food and affecting the uniformity of growth.

[0007] Furthermore, the control of the spreading radius depends entirely on the motor speed, which is easily affected by factors such as power grid voltage fluctuations and aging and wear of motor components, making it difficult to guarantee adjustment accuracy. Moreover, when the motor fails, the spreading radius cannot be adjusted, making it unable to adapt to the needs of different shrimp ponds or shrimp growth stages, resulting in poor equipment flexibility. Utility Model Content

[0008] To reduce the problem that existing shrimp feed dispensing nozzles rely on a single motor drive, and that the motor is easily corroded by rain, dust and grease in open-air environments, frequently malfunctioning and causing the nozzle to jam, this application provides a shrimp feed non-powered rotating nozzle.

The longitudinal section of the Y-shaped tee of the spraying component is connected to the feed flow channel, and the extension section is connected to the diversion section. There are at least two sets of diversion sections and they are symmetrically distributed, which realizes uniform feeding of shrimp without power drive. The spraying component is detachably connected to the distribution base through the first connector, which makes it easy to replace the spraying component with different degrees of curvature or oblique cut angle, adapt to the radius requirements of different shrimp ponds, and get rid of the influence of motor performance on radius control.

The spraying component also includes an S-shaped tee section, the middle part of which is detachably connected to the distributing base through a first connector. Each end is connected to at least one set of flow guides. This can achieve uniform feeding of shrimp feed without power, fine adjustment of the feeding radius, and adaptation to different shrimp pond scenarios. The curved structure of the S-shaped tee section can change the airflow direction, so that the oblique cut is oblique to the feeding radius circle, ensuring the formation of a stable pressure difference to drive rotation. The detachable spraying component makes it easy to replace different parts to adapt to different shrimp pond radius requirements.

[0019] Preferably, the spraying component further includes a rectangular tee section, the middle part of which is detachably connected to the material distribution base and connected by a first connector; each end of the rectangular tee section is connected to at least one set of drainage sections.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1: This embodiment discloses a non-powered rotary nozzle for shrimp feed, see [link]. Figure 1 and Figure 2 It includes a connecting pipe base 1 and a distributing base 2 connected to the main feed pipe. The distributing base 2 is rotatably connected to the connecting pipe base 1, and the connecting pipe base 1 and the distributing base 2 each have a feed flow channel 11 for feed circulation. The distributing base 2 is provided with a spraying component 3, which is detachably connected to the distributing base 2 and is connected to the feed flow channel 11. The spraying component 3 has a diversion part 31, which is connected to the feed flow channel 11. The diversion part 31 is provided in at least two sets and is symmetrically distributed relative to the distributing base 2.

[0030] Specifically, see Figure 1 and Figure 2 The feed flow channel 11 includes feed flow pipes, and feed flow pipes are respectively installed on the connecting pipe base 1 and the feed distribution base 2 for feed flow.

[0031] Specifically, see Figure 1 and Figure 2 The feed distribution base 2 and the connecting pipe base 1 are connected by a rotating member 4. The rotating member 4 is fixedly installed in the feed flow channel 11 of the feed distribution base 2 and is fitted onto the connecting pipe base 1. The feed distribution base 2 has a receiving portion 35, in which the rotating member 4 is installed, and the connecting pipe base 1 passes through the rotating member 4. The feed distribution base 2 is provided with a first locking member 6, which is locked onto the feed distribution base 2 and has one end abutting against the rotating member 4. The connecting pipe base 1 is provided with a second locking member 7, which is fitted onto the connecting pipe base 1 and has one end abutting against the rotating member 4.

[0032] See Figure 2 and Figure 3 The receiving part 35 includes a receiving groove formed on the powder base for receiving the rotating member 4. The rotating member 4 includes a support bearing installed in the receiving groove. The first retaining member 6 includes a first bearing retaining spring, which engages with the wall of the receiving groove of the dispensing base 2, and one end face abuts against the support bearing.

[0033] The second retaining element 7 includes a second bearing retaining ring, which is sleeved on the connecting pipe base 1, with one end face abutting against the supporting bearing, and the second bearing retaining ring is located below the first bearing retaining ring.

[0034] Specifically, see Figure 1 and Figure 2 The connecting pipe base 1 is provided with a rainproof component 12, which is installed at the connection between the material distribution base 2 and the connecting pipe base 1 and covers the end of the material distribution base 2 connected to the connecting pipe base 1.

[0035] The rainproof component 12 includes a rain cover, which is welded to the connecting pipe base 1 and covers the end of the material distribution base 2 connected to the connecting pipe base 1, thereby preventing rainwater, dust and other impurities from entering the support bearing and affecting the service life of the support bearing.

[0036] Specifically, see Figure 1 and Figure 2 The spraying component 3 includes a Y-shaped tee section 32. The longitudinal section 320 of the Y-shaped tee section 32 is detachably connected to the material distribution base 2 and is connected via a first connector 5. The extension sections 321 of the Y-shaped tee section 32 are respectively connected to at least one set of drainage sections 31.

[0037] See Figure 2 and Figure 3In one embodiment, the Y-shaped tee section 32 includes a Y-shaped tee pipe, the longitudinal section 320 of which is connected to the distribution base 2. The first connecting member 5 includes a connecting bolt and a connecting nut. The longitudinal section 320 of the Y-shaped tee pipe and the distribution base 2 each have a flange. After the connecting bolt passes through the flange of the longitudinal section 320 of the Y-shaped tee pipe in sequence, the connecting nut is screwed into the connecting bolt to lock the Y-shaped tee pipe. By setting the flange and the first connecting member 5, the spraying component 3 is detachably connected to the flange of the distribution base 2, allowing for quick replacement of spraying components 3 with different degrees of curvature or oblique cut angles 310, adapting to the radius requirements of different shrimp ponds, without relying on motor speed adjustment, and completely eliminating the influence of motor performance on radius control.

[0038] In one embodiment, the drainage section 31 includes a reducer, which is welded to an extension 321 of a Y-shaped tee. The reducer has a bevel 310, which is located on the reducer body at the end furthest from the reducer body where it connects to the Y-shaped tee. Furthermore, the diameter of the reducer gradually decreases from the connection point with the Y-shaped tee towards the bevel 310, thereby creating a pressure difference between the inside and outside of the reducer. When the negative pressure pump delivers feed from the feeding end, the negative pressure inside the pipe drives the distribution base 2 to rotate, thus achieving unpowered operation of the distribution base 2.

[0039] In one embodiment, if the extension 321 of the Y-shaped tee is straight, the central axis of the oblique cut 310 of the reducer is offset relative to the axial direction of the reducer, thereby guiding the airflow to deviate in direction. The airflow does not exit straight out, generating the power to push the material distribution base 2. The larger the angle of the oblique cut 310, the stronger the thrust of the airflow on the spray pipe, the faster the spraying speed, the greater the centrifugal force of the shrimp feed being thrown out, and the larger the spreading radius. Conversely, the radius decreases. The spreading radius can be precisely controlled by processing oblique cuts 310 at different angles.

[0040] In this embodiment, the drainage section 31 is provided in two sets and is symmetrically arranged relative to the longitudinal section 320 of the Y-shaped tee pipe. In other embodiments, the drainage section 31 can be provided in four sets, and the extension section 321 of the Y-shaped tee pipe has four segments, with each segment corresponding to a drainage section 31. Among the four extension segments 321, the symmetrical segments form a group, forming two groups. The extension segments 321 in one group are of the same length, while the lengths of the two segments in the other group are either longer or shorter than those in the first group, thereby achieving different feeding radii in the same pond and improving feeding efficiency.

[0041] Implementation principle: This technology connects the connecting pipe base 1 to the main conveying pipe. The connecting pipe base 1 and the distribution base 2 are rotatably connected by a support bearing (rotating part 4). Both are provided with feed flow pipes to form a feed flow channel 11. The feed distribution base 2 is detachably connected to the spraying part 3 via a flange and bolts and nuts (first connecting part 5). The longitudinal section 320 of the Y-shaped tee 32 of the spraying part 3 is connected to the feed flow channel 11, and the extension section 321 is connected to symmetrically distributed reducers (drainage part 31). During operation, the negative pressure pump delivers feed from the feeding end to the feed flow channel 11. When the feed flows through the reducer, the pressure difference is formed as the diameter of the reducer gradually decreases from the connection point with the Y-shaped tee 32 to the oblique cut end 310. This, combined with the oblique cut 310, causes the airflow direction to deflect (the straight extension section 321 is adapted to the oblique cut 310), generating the power to push the distribution base 2 to rotate around the support bearing, thus achieving unpowered rotation. The support bearing is fixed to the distribution base 2 and the connecting pipe base 1 respectively by the first and second bearing retaining rings (first and second retaining pieces 7). The rain cover on the connecting pipe base 1 covers the connection point to prevent impurities from entering and affecting the bearing life. The symmetrically distributed drainage parts 31 ensure rotational stability. The angle of the oblique cut 310 is adjusted by changing the thrust to adjust the feeding radius.

[0042] The core functions of this technical solution include uniform feeding of shrimp feed without power, precise adjustment of the feeding radius, and adaptation to different shrimp pond scenarios. The design of multiple diversion sections 31 allows for synchronous feeding of different radii within the same pond. Its advantages lie in its powerless design, completely eliminating reliance on motors and avoiding the impact of motor performance on feeding effectiveness; the detachable structure of the spraying component 3 facilitates replacement of parts with different bevel angles 310 or degrees of curvature to adapt to different shrimp pond radii; precise machining of the bevel angle 310 enables fine control of the feeding radius; symmetrical diversion sections 31 improve rotational stability; and the rain cover extends bearing life; the differentiated design of multiple diversion sections 31 improves feeding efficiency. This solution solves the problems of limited feeding radius and the impact of motor performance on feeding effectiveness caused by traditional nozzles relying on motor speed adjustment. It also addresses the issues of inaccurate feeding radius adjustment, poor adaptability, and the susceptibility of core components to impurities affecting their lifespan.

[0043] Example 2: See Figure 1 and Figure 4 The difference between this embodiment and Embodiment 1 lies in the different spraying component 3. Specifically, the spraying component 3 in this embodiment includes an S-shaped three-way section 33. The middle part of the S-shaped three-way section 33 is detachably connected to the material distribution base 2 and is connected through the first connector 5. Each end of the S-shaped three-way section 33 is connected to at least one set of drainage sections 31.

[0044] The S-shaped tee section 33 includes an S-shaped tee pipe, the middle of which is connected to the distribution base 2. The first connecting member 5 includes a connecting bolt and a connecting nut. The middle of the S-shaped tee pipe and the distribution base 2 each have a flange. After the connecting bolt passes through the flange of the distribution base 2 and the middle of the S-shaped tee pipe in sequence, the connecting nut is screwed into the connecting bolt to lock the S-shaped tee pipe.

[0045] The connection between the S-shaped tee and the drainage section 31 is curved, so the oblique cut 310 does not need to be cut obliquely. The central axis of the oblique cut 310 is parallel to the axial direction of the reducer. Because the S-shaped tee has a curved structure, it can change the airflow direction, so that the oblique cut 310 is oriented at an oblique angle to the material spreading radius circle, ensuring the formation of a stable pressure difference to drive rotation.

[0046] Example 3: See Figure 1 and Figure 5 The difference between this embodiment and the first embodiment lies in the different spraying component 3. Specifically, the spraying component 3 includes a rectangular three-way section 34. The middle part of the rectangular three-way section 34 is detachably connected to the material distribution base 2 and is connected through the first connector 5. Each end of the rectangular three-way section 34 is connected to at least one set of drainage sections 31.

[0047] The rectangular tee section 34 includes a rectangular tee box, the middle of which is connected to the distribution base 2. The first connecting member 5 includes a connecting bolt and a connecting nut. The middle of the rectangular tee box and the distribution base 2 each have a flange. After the connecting bolt passes through the flange of the distribution base 2 and the middle of the rectangular tee box in sequence, the connecting nut is screwed into the connecting bolt to lock the rectangular tee box.

[0048] The flow guide 31 connected to the rectangular tee box is integrally formed with its body and is also rectangular in shape. The rectangular tee box is set in an arc shape from the middle to both ends, thereby changing the airflow direction and making the oblique cut 310 face an oblique angle with the material spreading radius circle to ensure the formation of a stable pressure difference to drive rotation.

[0049] All three embodiments of this technology share common advantages: First, they adopt a power-free drive design, using a pressure difference created by the gradual change in the diameter of the reducing pipe, combined with a three-way structure (Y-shaped, S-shaped, rectangular) to change the airflow direction and generate rotational power, completely eliminating dependence on the motor and avoiding the impact of motor performance fluctuations on the spreading effect; Second, the spraying component 3 and the distributing base 2 adopt a detachable connection structure of flange + bolts and nuts, allowing for quick replacement of the spraying component 3 to suit different scenarios, improving equipment adaptability; Third, a rainproof cover is provided to cover the base connection, effectively preventing rainwater, dust, and other impurities from entering the support bearing, and combined with the fixing design of the bearing retainer, significantly extending the service life of the core rotating components; Fourth, the diversion section 31 adopts a symmetrical distribution design (at least two sets), ensuring the rotational stability of the equipment and achieving uniform spreading of shrimp feed. Meanwhile, each embodiment has its own unique advantages: the Y-shaped tee section 32 of Embodiment 1 can be extended to four sets of drainage sections 31, and multi-radius feeding in the same pond can be achieved through extension sections 321 of different lengths, thereby improving feeding efficiency; the S-shaped tee section 33 of Embodiment 2 uses its own bending structure to change the airflow direction, so that the oblique cut 310 does not need additional offset processing, simplifying the processing technology; the rectangular tee box of Embodiment 3 is integrally formed with the drainage section 31 and has an arc design, which simplifies the assembly process and can stably change the airflow direction, thereby improving the overall structure and reliability.

[0050] This series of technical solutions addresses several key issues with traditional shrimp feed nozzles: Regarding common issues, it resolves the limitations on the feeding radius caused by reliance on motor speed regulation, the impact of motor failure on feeding continuity, and high motor maintenance costs; it addresses the fixed structure of traditional nozzles and the high replacement costs when adapting to shrimp ponds of different sizes; it addresses the lack of protection for traditional rotating parts, making them susceptible to corrosion and resulting in short lifespans; and it addresses the uneven feeding caused by unstable rotation in traditional feed distribution. Each embodiment also addresses specific problems: Embodiment 1 solves the problem of difficulty in achieving precise feeding across multiple radii in the same pond with a single nozzle, resulting in low feeding efficiency; Embodiment 2 solves the problem of the traditional oblique cut 310 requiring precise offset processing, which is complex and costly; Embodiment 3 solves the problem of easy loosening and insufficient airflow guidance stability in the separate assembly of the traditional feed spraying component 3 and the guide section 31, while also reducing assembly difficulty and subsequent maintenance costs.
