Description

Technical Field

[0001] This utility model relates to the field of livestock feeding technology with adjustable feed output, and in particular to a livestock feeding vehicle with adjustable feed output for pig farming. Background Technology

[0002] In large-scale, intensive pig farming, the feeding process is one of the key links to ensure the healthy growth of pigs and improve breeding efficiency. With the expansion of breeding scale and the improvement of breeding precision, traditional feeding methods have gradually exposed many problems. In the early small-scale breeding, feeding was mostly done manually by carrying feed buckets or ladles, which was not only labor-intensive and inefficient, but also relied entirely on experience to control the amount of feed, which easily led to overfeeding or underfeeding. With the initial development of breeding mechanization, simple pushcart-type feeding equipment appeared, but the feed outlet of this type of equipment is mostly of a fixed size, which cannot adjust the amount of feed according to the different growth stages of pigs (such as piglets, fattening pigs, sows, and breeding pigs).

[0003] Therefore, we propose a pig feeder with adjustable feed output to solve the above problems. Utility Model Content

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] Example 1, as Figure 1 and Figure 2As shown, a pig-raising feeder with adjustable feed output includes a base 1, a conveying mechanism 2 installed on the upper end of the base 1, a stirring mechanism 3 installed on the upper end of the conveying mechanism 2, a box cover 5 threadedly connected to the upper end of the stirring mechanism 3, a motor 4 threadedly connected to the right side of the stirring mechanism 3, a feeding hopper 6 slidably connected to the left end of the conveying mechanism 2, a rebound mechanism 7 fixedly connected to the left end of the conveying mechanism 2, a limit mechanism 8 fixedly connected to the left end of the feeding hopper 6, and a micro switch 9 installed on the right end of the limit mechanism 8 and the left end of the conveying mechanism 2, which can be turned on or off by a light touch.

[0020] The base 1 is equipped with four swivel wheels made of highly elastic rubber with an anti-slip tread pattern, adapting to different ground conditions in pig farms, including concrete and muddy surfaces. Each wheel is equipped with a brake; pressing the brake pedal will lock the wheel in place, preventing the feed cart from moving during feeding.

[0021] Furthermore, such as Figure 2 As shown, the box cover 5 includes a cover plate 51, a cover door 52 is rotatably connected to the upper part of the cover plate 51, and a handle 53 is installed on the upper part of the cover door 52.

[0022] Specifically, when it is necessary to add materials or clean the inner cavity of the mixing mechanism 3, the cover door 52 can be opened by pulling the handle 53 to complete the above operations. It should be noted that the cover plate 51 is threadedly connected to the mixing mechanism 3. When the internal parts need to be inspected or the equipment replaced, the cover plate 51 can be removed for subsequent operations.

[0023] During implementation, the cover door 52 ensures that pig feed raw materials can enter the mixing mechanism 3 conveniently and flexibly, and also prevents dust from entering and raw materials from splashing out.

[0024] Furthermore, such as Figure 3 As shown, the stirring mechanism 3 includes a stirring box 31, which is threadedly connected to the cover plate 51. The stirring box 31 adopts a funnel-shaped design that is wider at the top and narrower at the bottom. A rotating shaft 32 is rotatably connected to the inner cavity of the stirring box 31. The motor 4 is rotatably connected to the rotating shaft 32 through a coupling. The motor 4 can drive the rotating shaft 32 to rotate. Spiral stirring blades 33 are installed on the outer surface of the inner cavity of the stirring box 31. A sliding plate 34 is slidably connected to the lower part of the inner cavity of the stirring box 31. The width of the sliding plate 34 is greater than the width of the stirring box 31. A handle 35 is installed on one side of the sliding plate 34. The handle 35 is located outside the stirring box 31.

[0025] It should be noted that initially, the sliding plate 34 is tightly fitted to the inner wall of the mixing tank 31 to prevent the added raw materials or other liquids from flowing down.

[0026] Specifically, both the rotating shaft 32 and the spiral mixing blades 33 are made of wear-resistant materials. When the pig feed ingredients are added into the mixing tank 31, the motor 4 is started, causing the mixing tank 31 to rotate and drive the spiral mixing blades 33 to rotate. Various pig feed ingredients are forcibly dispersed, and after a period of mixing, the various ingredients are evenly mixed to form pig feed. After mixing is completed, pulling the handle 35 opens the sliding plate 34, allowing the feed to flow out through the drop channel and fall into the conveying mechanism 2.

[0027] For further details, please refer to [link / reference]. Figure 4 The conveying mechanism 2 includes a conveying box 21. A pulley and belt are installed on one side of the conveying box 21 and are rotatably connected to the output end of the motor 4. The inlet of the conveying box 21 is connected to the outlet at the bottom of the mixing box 31. The upper part of the conveying box 21 is a cuboid design, and its length and width are consistent with the lower part of the mixing box 31, so as to better connect, install and discharge materials. A rotating shaft 22 is installed in the inner cavity of the conveying box 21. A spiral blade 23 is installed on the outer surface of the rotating shaft 22. A perforated disc 24 is installed on the side of the rotating shaft 22 away from the motor 4 through a connecting bearing.

[0028] During implementation, when pig feed flows into the conveyor box 21, the rotating shaft 22 is connected to the output end of the motor 4 via a pulley and belt. This means that after the motor 4 starts, it can also drive the rotating shaft 22 to rotate, simultaneously driving the spiral blades 23 to rotate, thus conveying the flowing feed towards the outlet. This dual-power drive via a single motor achieves the goal of saving electricity.

[0029] Specifically, a perforated disc 24 is provided at the outlet end of the conveying mechanism 2. The perforated disc 24 has multiple holes of the same size, which facilitates the pig feed to enter the outer feeding hopper 6 through the holes.

[0030] In summary, the implementation process of this embodiment is divided into: Feeding and mixing: Open the cover 52 of the tank lid 5 and add feed ingredients into the mixing tank 31. Start the motor 4, which drives the rotating shaft 32 to rotate via the coupling, thereby driving the spiral mixing blades 33 to mix the raw materials. Figure 3 After mixing is complete, the operator pulls handle 35 to remove the sliding plate 34 from the bottom of the mixing tank 31, forming a discharge channel.

[0031] Delivery and quantitative distribution: Feed falls from mixing tank 31 into conveying tank 21. Motor 4 synchronously drives rotating shaft 22 to rotate via pulley. Spiral blades 23 push feed towards the perforated disc 24 at the outlet end. The holes of the perforated disc 24 evenly distribute the feed into the loading hopper 6. Here, motor 4 simultaneously drives mixing and conveying, realizing dual-function linkage.

[0032] Example 2, see Figure 5 good Figure 6The filling hopper 6 includes an upper half hopper 61 and a lower half hopper 62. A movable disc 64 is installed on the bottom left side of the upper half hopper 61. The movable disc 64 is fixed to the upper half hopper 61. Two rotating arms 63 are rotatably connected to the movable disc 64 protruding from the outer surface of the upper half hopper 61 and the lower half hopper 62. One side of each rotating arm 63 is fixedly connected to the lower half hopper 62. A metal rod 67 is slidably connected to the middle of the rotating arm 63. The rotating arm 63 can drive the upper half hopper 61 and the lower half hopper 62 to slide on the surface of the metal rod 67. The side of the metal rod 67 away from the upper half hopper 61 is fixedly connected to one side of the perforated disc 24. A fixing plate 66 is fixedly connected to the side of the movable disc 64 away from the upper half hopper 61 by a metal rod. Electric push rods 65 are rotatably connected to both sides of the lower part of the fixing plate 66.

[0033] Furthermore, the micro switch 9 installed on one side of the conveyor box 21 is initially in contact with the upper half of the barrel 61, but it will not trigger the micro switch 9.

[0034] Specifically, pig feed overflows through the porous structure of the porous disc 24 into the enclosed space formed by the upper half-bucket 61, the lower half-bucket 62, and the movable disc 64. When the amount of pig feed inside reaches a certain level, it is compressed by the subsequent feeding of raw materials, pushing the movable disc 64 to slide on the metal rod 67, thus moving the upper half-bucket 61 and the lower half-bucket 62 and expanding the internal space. As the movement continues, when the movable disc 64 contacts a microswitch 9 installed on the porous metal plate 82, the microswitch 9 is activated. At this time, the electric push rod 65 is activated, and its telescopic rod retracts, causing the lower half-bucket 62 to rotate downwards, thereby causing the pig feed inside to pour into the pig feed trough. Due to the force of gravity and the impact of the pouring pig feed during the rotation of the lower half-bucket 62, a portion of the force is transmitted to the electric push rod 65, causing the electric push rod 65 to rotate around the fixed plate 66, thus completing the synchronous rotation during the retraction process so that the two collide with each other.

[0035] It should be noted that, for reference Figure 5 To drive the lower half of the bucket 62 to rotate downwards, the electric push rod 65 is initially in an inclined state, and its extension rod is initially in an extended state. For example... Figure 7 As shown, the electric push rod 65 retracts, and the lower half of the drum 62 rotates downward to pour out the material.

[0036] Furthermore, to achieve the goal of resetting the lower half of the drum 62 after the material is poured, a springback device was designed, such as... Figure 5 As shown in Figure 6, the rebound mechanism 7 includes a slide block 72 and two springs 73. A slider 71 is slidably connected to the slider 71. The lower part of the slider 71 is fixedly connected to the upper half of the barrel 61. When the upper half of the barrel 61 moves, it can slide the slider 71 on the slide block 72. One side of the slide block 72 is fixedly connected to the conveyor box 21. One side of the two springs 73 is connected to two rectangular plates installed on the movable disc 64, and the other end is connected to the conveyor box 21.

[0037] Specifically, when the moving disc 64 moves, it stretches the two springs 73. At this time, the two springs 73 store elastic potential energy. After the pig feed is poured out, the springs 73 pull the moving disc 64, the upper half-bucket 61, and the lower half-bucket 62 back to their initial positions. Since the springs 73 will generate a certain amount of shaking and stretching distance when they rebound, the upper half-bucket 61 will lightly touch another micro switch 9 installed on the conveyor box 21, which will activate the electric push rod 65 to extend its telescopic rod and push the lower half-bucket 62 back to its initial position, forming a closed space with the moving disc 64 and the upper half-bucket 61 to continue loading.

[0038] Furthermore, to allow the feeding hopper 6 to hold different amounts of pig feed, a limiting device is installed to accommodate different loading amounts, such as... Figure 6 and Figure 7 As shown, the limiting mechanism 8 includes a mounting disc 81 and a limiting pin 84. A single-hole metal plate 83 is fixedly connected to the side of the mounting disc 81 near the material barrel 6. A multi-hole metal plate 82 is slidably connected to the mounting disc 81. The multi-hole metal plate 82 is located directly below the single-hole metal plate 83. The multi-hole metal plate 82 has several holes, and the single-hole metal plate 83 has one hole. The limiting pin 84 is set in the holes of the single-hole metal plate 83 and the multi-hole metal plate 82 to fix the position of the multi-hole metal plate 82. A micro switch 9 is installed on the side of the multi-hole metal plate 82 near the material barrel 6.

[0039] Specifically, removing the limiting pin 84 allows the perforated metal plate 82 to slide, causing a microswitch 9 mounted on the perforated metal plate 82 to move, increasing the distance the moving disc 64 moves towards the perforated metal plate 82, thereby expanding the internal space of the feeding hopper 6. By inserting the limiting pin 84, which passes through the single-hole metal plate 83, into different holes on the perforated metal plate 82, the perforated metal plate 82 can be fixed. The moving disc 64 needs to move different distances to touch the microswitch 9 on the perforated metal plate 82, activating the electric push rod 65 to flip the lower half of the hopper 62, thus obtaining different loading amounts of pig feed, corresponding to the feed requirements of piglets, fattening pigs, sows, and other pigs of different ages.

[0040] It should be noted that the two microswitches 9 act as position sensors, triggering the relay to control the circuit's on / off state via mechanical contact. They are electrically connected to the electric push rod 65. When the moving disc 64 is loaded to the set amount, it pushes the microswitches 9 on the perforated metal plate 82. The internal spring of the microswitch 9 is pressed, momentarily opening the normally closed contact or closing the normally open contact, triggering the electric push rod 65 to retract. During unloading and resetting, the upper half of the drum 61 touches the microswitches 9 on the side of the conveyor box 21, similarly triggering the electric push rod 65 to extend via the spring action. Two microswitches 9 control the extension and retraction of the push rod, featuring a single-pole double-throw (SPDT) contact design. The compatible model is RLXW20-11M. Its 1.5mm trigger stroke, IP54 protection, and SPDT contacts meet the requirements for sensitive triggering and dust protection. The compatible model for the electric push rod 65 is the Thomson series (such as HD10-400), with a stroke of 400mm, a speed of 20mm / s, and a built-in limit switch (automatically cuts off power when the retraction / extension end is reached to protect the motor). It can match the needs of flipping and the environment of the farm.

[0041] Built-in limit switch (automatically cuts off power when the contraction / extension end is reached to protect the motor).

[0042] In summary, during implementation of this embodiment, the pig feed flowing out from the perforated disc 24 of the conveying mechanism 2 enters the enclosed space formed by the upper half-bucket 61, the lower half-bucket 62, and the movable disc 64 in the feeding hopper 6. As the pig feed accumulates, the internal pressure gradually increases, pushing the movable disc 64 to slide on the metal rod 67. The movable disc 64 drives the upper half-bucket 61 and the lower half-bucket 62 to move synchronously. At this time, the upper half-bucket 61 drives the slider 71 in the rebound mechanism 7 to slide on the slide block 72, while stretching the two springs 73 connected to the movable disc 64, so that the springs 73 store elastic potential energy. When the moving disc 64 moves to the contact limit mechanism 8, the micro switch 9 on the porous metal plate 82 is triggered, activating the electric push rod 65 at the bottom of the fixed plate 66 in the feeding hopper 6. Since the electric push rod 65 is initially tilted and its telescopic rod is extended, it retracts, causing the lower half-bucket 62 to rotate downwards via the rotating arm 63, pouring the pig feed into the feeding trough. During the rotation, the electric push rod 65 rotates around the fixed plate 66 to avoid collisions. After the pig feed is poured out, the stretched spring 73 in the rebound mechanism 7 releases its elastic potential energy, pulling the moving disc 64, the upper half-bucket 61, and the lower half-bucket 62 back to their initial positions. During the reset process, the upper half-bucket 61 lightly touches another micro switch 9 on the conveyor box 21, which activates the electric push rod 65, extending its telescopic rod and pushing the lower half-bucket 62 back to its initial position, re-forming a closed space with the upper half-bucket 61 and the moving disc 64, and continuing to feed. If the feed amount needs to be adjusted to suit different pig groups, the limit pin 84 in the limit mechanism 8 can be removed, the perforated metal plate 82 can be slid, and the micro switch 9 on it can be moved. The distance required for the moving disc 64 to trigger the micro switch 9 can be changed. Then, the limit pin 84 can be passed through the single-hole metal plate 83 and inserted into the corresponding hole on the perforated metal plate 82 to fix the position of the perforated metal plate 82, thereby realizing the adjustment of the feed amount to meet the feed needs of piglets, fattening pigs, sows and other pigs of different ages.

[0043] It should be noted that the specific installation method, circuit connection method, and control method of the motor 4 and electric push rod 65 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
