Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, specifically a feed spreading device. Background Technology

[0002] In modern poultry farming, some breeding poultry, due to their biological characteristics or farming requirements, must be raised on the ground; breeding ducks are a typical example. During the rearing of breeding ducks, a prominent and urgent problem has emerged: significant differences in feeding speed among individuals within the flock. Dominant breeding ducks, leveraging their advantages, exhibit extremely fast feeding speeds, while weaker breeding ducks, limited by their physique, size, or other factors, show a noticeably slower feeding speed.

[0003] This uneven feeding rate, as the rearing cycle lengthens, will lead to a series of adverse consequences. The growth gap between strong and weak individuals will widen, severely reducing the evenness of the flock and hindering overall farming efficiency. From an animal health perspective, weaker breeding ducks will not receive sufficient nutrition for a long time, resulting in stunted growth and development, weakened immunity, and increased susceptibility to various diseases, thus affecting the overall health of the flock. Furthermore, later egg production is closely related to the nutritional accumulation and health of the breeding ducks during their growth stages; uneven growth will make it difficult to achieve the ideal egg production rate.

[0004] To effectively reduce the disparity in strength among breeding ducks, improve flock uniformity, promote healthy growth, and ultimately increase egg production, it is necessary to address the issue of feed distribution. This requires ensuring that feed can be evenly distributed throughout the breeding area in a short time, allowing each breeding duck, regardless of its strength, to access food in a relatively equitable environment.

[0016] The second support frame is fixedly connected to the end of the first support part on its upper side;

[0017] A set of movable components is provided for each of the second support frames. The movable components are equipped with rollers and can slide along the external structure.

[0018] Preferably, the feed inlet is provided at the upper end of the feed cylinder and faces upward, and the discharge outlet is provided at the lower end of the feed cylinder and faces directly downward;

[0019] The material spreading component is located directly below the outlet of the feed cylinder, and the material spreading component and the feed cylinder are coaxial.

[0020] Preferably, the stirring assembly includes:

[0021] The stirring motor is fixedly mounted on the first support.

[0022] The stirring rod is linked to the motor shaft of the stirring motor, and the stirring motor can drive the stirring rod to rotate; the stirring rod is vertically arranged and extends into the inside of the feed cylinder;

[0023] The first stirring element is a plate body arranged around the stirring rod, and at least two first stirring elements are provided.

[0024] Preferably, the stirring assembly further includes:

[0025] The second stirring element is a plate surrounding the stirring rod, and at least two second stirring elements are provided; the second stirring element is located below the first stirring element;

[0026] The length of the first stirring element is greater than the length of the second stirring element.

[0027] Preferably, two of each of the first and second stirring components are provided;

[0028] Both the first and second stirring components are inclined, with the plane containing the axis of the stirring rod as the middle plane, and the projections of the two first stirring components and the two second stirring components on the middle plane form an "X" shape.

[0029] Preferably, the upper part of the feed cylinder is cylindrical, and the lower part is an inverted frustum-shaped cylinder, with the upper end of the lower part fixedly connected to the upper part; the bottom end of the lower part is the discharge port.

[0030] The material spreading mechanism also includes:

[0031] The material spreading shell is a frustum-shaped cylinder. The upper end of the material spreading shell is fixedly connected to the lower end of the feeding cylinder, and the upper end of the material spreading shell is a small area.

[0032] The material spreading component is located below the material spreading shell.

[0033] Preferably, the length of the major axis of the spreading disc is R1, the length of the minor axis is R2, and the ratio of R1:R2 is 1.5:1 to 2:1.

[0038] Compared with existing technologies, it has the following beneficial effects:

[0039] 1. Improve the uniformity of feed distribution and reduce the growth gap among groups.

[0040] The feeding mechanism employs an elliptical feeding disc paired with radially distributed feeding plates. When the feeding component rotates at high speed, the feed is thrown outwards by the feeding plates under centrifugal force. The elliptical disc allows for differentiated throwing distances of the feed in different directions, and combined with the uniform distribution effect of the radial feeding plates, the feed can be widely and evenly covered throughout the breeding area. This design effectively avoids the problem of concentrated feed accumulation in traditional feeding methods, allowing weaker breeding poultry to easily access food, reducing growth differences caused by competition for food between strong and weak individuals, and significantly improving the uniformity of feed acquisition for the entire group.

[0041] 2. Improve spreading efficiency to meet the needs of large-scale farming.

[0042] The mixing component inside the feed cylinder can mix the incoming feed in real time, preventing feed from clumping and clogging the discharge port, and ensuring that the feed is continuously and stably delivered to the spreading device. Compared with manual feeding or simple equipment, this equipment can complete the feed coverage of a large area in a short time, meeting the needs of efficient feeding in large-scale farming and reducing the intensity of manual labor.

[0043] 3. The structure is stable and reliable, and it is suitable for ground-based breeding scenarios.

[0044] The support mechanism is stably connected to the feeding mechanism through the first support part, and the second support part can be used with external structures (such as breeding sheds, moving tracks, etc.). Combined with the roller design of the second support part, the equipment can move within the breeding area, which also helps to improve the uniformity of feed distribution within the breeding area.

[0045] 4. Promote the healthy growth of breeding poultry and improve the economic benefits of breeding.

[0046] Even and efficient feed distribution ensures that each breeding bird receives sufficient and balanced nutrition, reducing problems such as weakened immunity and stunted growth caused by insufficient feed intake, and promoting healthy development. Improved flock uniformity further increases egg production in later stages, reduces losses during the breeding process, optimizes economic benefits throughout the entire breeding cycle, and provides strong support for the large-scale and refined development of the livestock industry.

[0057] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0058] Please see Figures 1-6 This application provides the following technical solutions:

[0059] A feed spreading device includes a support mechanism 1, a feeding mechanism 2, and a spreading mechanism 3. The support mechanism 1 provides support for the feeding mechanism 2 and the spreading mechanism 3. The support mechanism 1 includes a first support part 11 and a second support part 12. The first support part 11 is a horizontally arranged rectangular frame; the second support part 12 is used to connect to an external structure. The horizontal arrangement of the first support part 11 is based on the direction of the device in its operating state; the vertical direction mentioned later also refers to the direction of the device in its operating state. In this design, the first support part 11 is directly a rectangular plate. Depending on the actual situation, if a large amount of feed needs to be carried at once, a more complex and robust frame structure can be selected. The feeding mechanism 2 is connected to the first support part 11. The feeding mechanism 2 includes a feeding cylinder 21, which has an inlet and an outlet; a stirring assembly 22 is installed inside the feeding cylinder 21. The feeding cylinder 21 has an overall annular cylindrical structure. The upper part of the feeding cylinder 21 is cylindrical, and the lower part is an inverted frustum-shaped cylinder. The upper end of the lower part is fixedly connected to the upper part. The upper end of the upper part is provided with a feeding port facing upwards, and the bottom end of the lower part is a discharging port facing downwards. A spreading mechanism 3 is provided below the feeding cylinder 21. The spreading mechanism 3 includes a spreading component 31. The spreading component 31 is located below the discharging port of the feeding cylinder 21 and is rotatably connected to the support mechanism 1. The spreading component 31 includes an elliptical spreading plate 311. Several spreading plates 312 are fixedly provided on the spreading plate 311. The spreading plates 312 extend upwards towards the spreading plate 311 and are radially distributed on the spreading plate 311.

[0060] With the structure of this design, the equipment is erected at the location where feed needs to be scattered using the second support 12. Then, the spreading component 31 is rotated to enter the feed-scattering state. Feed is then loaded into the feed cylinder 21, and after passing through the feed cylinder 21, it falls onto the spreading component 31 and is scattered around the equipment as the spreading component 31 rotates. To prevent feed from clumping and getting stuck in the feed cylinder 21, a stirring component 22 is installed inside the feed cylinder 21 to break up the feed.

[0061] One of the key differences between this solution and conventional feed dispensing equipment is the elliptical shape of the feed spreader 311. Compared to the conventional circular spreader, this shape allows for a wider feed spreading range. Conventional circular spreaders typically spread feed within a fixed radius, resulting in a circular feed band due to variations in feed particle weight. This elliptical spreader, however, causes a significant difference in landing positions between feed ejected from the short axis and feed ejected from the long axis. Combined with the weight differences in the feed, this creates a wider feed band, resulting in a more even feed supply to the breeding ducks.

[0062] Based on the above implementation scheme, one second support part 12 is provided on each side of the first support part 11; the second support part 12 includes a second support frame 121 and a moving component 122. The upper side of the second support frame 121 is fixedly connected to the end of the first support part 11; a set of moving components 122 is provided for each second support frame 121, and the moving component 122 is provided with rollers, which can slide along the external structure. In this scheme, the moving component 122 is provided with two rollers. A slide rail can be laid in the breeding area to facilitate the movement of the moving component 122 along the slide rail.

[0063] As a further optimization of the solution, a motor can also be configured for the moving component 122, which drives the rollers to move, thereby realizing the automatic movement of the equipment.

[0064] Based on the above implementation scheme, the stirring assembly 22 includes a stirring motor 221 fixedly mounted on the first support 11. The motor shaft of the stirring motor 221 is coaxially connected to a stirring rod 222, which extends vertically into the feed cylinder 21. The stirring motor 221 can drive the stirring rod 222 to rotate. A first stirring element 223 and a second stirring element 224 are respectively mounted on the stirring rod 222. Both the first stirring element 223 and the second stirring element 224 are plate-shaped, with two plates respectively mounted on the stirring rod 222. The two second stirring elements 224 are located below the two first stirring elements 223, and the length of the first stirring element 223 is greater than the length of the second stirring element 224.

[0065] This structure, with a first agitator 223 and a second agitator 224 positioned at different heights inside the feed cylinder 21, effectively disperses the feed. This solves the problem of feed clumping during storage and also prevents blockages at the discharge port when feed enters the feed cylinder 21.

[0066] Based on the above implementation scheme, the two first stirring components 223 and the two second stirring components 224 are all inclined, with the plane containing the axis of the stirring rod 222 as the middle plane, and the projections of the two first stirring components 223 and the two second stirring components 224 on the middle plane form an "X" shape.

[0067] It is important to note that the tilt directions of the two first agitator components 223 and the second agitator component 224 on the same side are opposite. This arrangement enhances the feed-dispersing effect of the agitator component 22, preventing the feed from being simply stirred in one direction.

[0068] Based on the above implementation scheme, the material spreading mechanism 3 also includes a material spreading shell 32, which is a frustum-shaped cylinder. The upper end of the material spreading shell 32 is fixedly connected to the lower end of the feed cylinder 21, and the upper end of the material spreading shell 32 has a small area. The material spreading component 31 is located below the material spreading shell 32, that is, the material spreading component 31 is located directly below the outlet of the feed cylinder 21, and the material spreading component 31 and the feed cylinder 21 are coaxial. The material spreading component 31 is also fixedly connected to the stirring rod 222.

[0069] The first stirring component 223, the second stirring component 224, and the spreading component 31 in this scheme are all driven by the stirring motor 221, and the three rotate synchronously.

[0070] As an extension of this solution, the stirring motor 221 can also be driven in a linkage manner with the first stirring component 223, the second stirring component 224, and the dispensing component 31. For example, a drive rod is fixedly connected to the motor shaft of the stirring motor 221, the stirring rod 222 is fixedly connected to the first support part 11, and the first stirring component 223, the second stirring component 224, and the dispensing component 31 are rotatably connected to the stirring rod 222 through a synchronous pulley, and then the drive rod is linked to each of the three components through another corresponding synchronous pulley and a synchronous belt. By simply adjusting the size of the synchronous pulley to form different transmission ratios, different speeds for the three components can be achieved.

[0071] Based on the above implementation scheme, with the long axis length of the spreading disc 311 as R1 and the short axis length as R2, the ratio of R1:R2 is 1.5:1~2:1. The R1:R2 ratio adopted in this scheme is 1.618:1, which is the golden ratio.

[0072] One end of the spreading plate 312 extends toward the central axis of the spreading disc 311, and the other end extends to the edge of the spreading disc 311. The spreading plate 312 is an arc-shaped plate; and the angle between the surface of the spreading plate 312 and the surface of the spreading disc 311 is not 90°.

[0073] See Figure 5 and Figure 6 The spreading plate 312 is an irregularly shaped plate, with an overall arc shape, and its edges correspond to the edge length of the spreading disk 311. The area of ​​the spreading plate 312 near the center of the spreading disk 311 is thinner, while the area near the edge of the spreading disk 311 is thicker. All spreading plates 312 are spaced apart from the center of the spreading disk 311, meaning there is no connection point between the spreading plates 312 and the center of the spreading disk 311. Furthermore, both sides of the spreading plate 312 are inclined relative to the spreading disk 311. For ease of explanation, [the following is a simplified description]. Figure 5 The direction in which the spreading disc 311 rotates clockwise is direction one, and the direction in which it rotates counterclockwise is direction two. The angle between the side of the spreading plate 312 facing direction one and the surface of the spreading disc 311 is an acute angle, and the angle between the side of the spreading plate 312 facing direction two and the surface of the spreading disc 311 is an obtuse angle. The two angles can be 45° and 135° respectively.

[0074] When in use, the feed spreading component 31 rotates counterclockwise, and the feed falls onto the spreading disc 311. Then, as the feed spreading component 31 rotates, the feed moves towards the outside of the spreading disc 311 under the action of centrifugal force. During the movement, the feed slides along the surface of the spreading plate 312. Because the angle of the spreading plate 312 towards its direction of movement is an obtuse angle, the feed will slide towards the upper edge of the plate surface during the movement along the spreading plate 312, which provides the feed with an upward throwing force. However, during the feed scattering process, because the feed falls onto the scattering disc 311 not in individual particles, but rather a relatively large number of feed particles continuously fall onto the scattering disc 311, the feed is distributed outwards on the surface of the scattering disc 311 and the scattering plate 312. Under this effect, the difference in the feed particles themselves, combined with the effect of being thrown out at different positions on the scattering disc 311 and the scattering plate 312, allows the feed to form a larger scattering surface, thus allowing the breeding ducks to eat over a wider area. This solves the problem of strong breeding ducks crowding out weak breeding ducks when traditional mechanical feed scattering occurs.

[0075] Based on the above implementation scheme, as a further extension of the scheme, two spreading discs 311 are provided, with two spreading elements 31 distributed vertically, and the projections of the two spreading elements 31 on the horizontal plane do not overlap. The two spreading discs 311 are arranged in a cross shape, with the upper long axis corresponding to the lower short axis. The upper spreading disc 311 has a discharge hole in the middle, which can be one or more, allowing some feed to fall onto the lower spreading disc 311 through the upper spreading disc 311. The lower spreading element 31 is designed to be smaller than the upper spreading element 31, that is, both the long axis and short axis of the lower spreading disc 311 are smaller than those of the upper spreading disc 311. This arrangement further increases the spreading range of the feed.
