Description

Technical Field

[0001] This utility model belongs to the field of animal husbandry technology, and in particular relates to an automatic feeding device for animal husbandry. Background Technology

[0002] As modern livestock farming develops towards large-scale and intensive operations, automated feeding equipment has become a key facility for ensuring breeding efficiency and reducing labor costs. These devices are usually equipped with large storage silos that can pre-mix compound feeds containing concentrates, powders, moisture, and even health supplements, and achieve automatic feeding through timed and quantitative control. However, the long-term static storage of such water-containing materials can easily lead to caking and sticking in the hopper due to moisture migration, material adsorption, and the squeezing effect of their own gravity, forming large lumps or solid arched structures (i.e., "silo stacking" or "arching" phenomena).

[0003] In existing technologies, to solve the problem of poor material discharge, augers (screw conveyors) are commonly installed at the bottom outlet of the hopper for forced discharge. However, this method has inherent defects: the auger can only act on the local material it directly contacts. When the material in the upper layer of the hopper forms a stable "arch bridge" structure due to caking, the auger cannot effectively "pull" the material down. Instead, it is easy to form a void after clearing the surrounding material, resulting in material breakage. At this time, even if the auger continues to rotate idling, it cannot effectively impact and destroy the stress balance point of the "arch bridge" structure, and the arch breaking effect is not ideal.

[0004] Therefore, we propose an automatic feeding device for livestock farming to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of feed shortage caused by empty space in the hopper in the prior art, and to propose an automatic feeding device for livestock farming.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic feeding device for livestock farming includes a mounting frame and a hopper fixed to the mounting frame. The bottom of the hopper has a discharge port, and the discharge port is equipped with an openable and closable material-blocking mechanism. A material trough for receiving materials is located below the hopper. An arch-breaking mechanism is provided inside the hopper, and the arch-breaking mechanism includes: The driving component is rotatably disposed inside the hopper and is driven by a drive motor fixed to the outer wall of the hopper; At least two vertically arranged feeding rods are distributed laterally in the hopper, and the top of the feeding rods is provided with a guide rod that can be retracted when moving upward and expanded when moving downward; A connecting rod is connected between the drive component and the bottom of each of the feeding rods, and is used to convert the rotational motion of the drive component into the up-and-down reciprocating motion of the feeding rods; A limiting rod is fixed laterally inside the hopper, and each of the feeding rods has a limiting slot in the middle that slides with the limiting rod.

[0007] Preferably, the driving component includes at least three coaxially arranged connecting rings, and adjacent connecting rings are fixedly connected by an eccentrically arranged eccentric rod; One end of each connecting rod is rotatably connected to the corresponding eccentric rod, and the other end is rotatably connected to the bottom of the corresponding accelerator rod.

[0008] Preferably, each of the eccentric rods is uniformly offset along the circumference of the connecting ring.

[0009] Preferably, the guide rod includes two symmetrically arranged side plates, the tops of the two side plates being rotatably connected to the top of the feed rod.

[0010] Preferably, the material blocking mechanism includes: Two arc-shaped baffles are designed to match the arc-shaped profile of the hopper outlet. Two connecting rods, one end of which is fixedly connected to the side of the corresponding arc-shaped baffle, and the other end is rotatably connected to the side wall of the hopper; A control component is used to synchronously drive the two connecting rods to rotate around their axis to achieve the opening and closing of the two arc-shaped baffles.

[0011] Preferably, the control component includes: A drive cylinder is fixedly installed on the outer wall of the hopper; A guide frame is fixedly connected to the end of the piston rod of the drive cylinder, and a horizontal guide groove is provided on the guide frame; The guide post is fixed to the connecting rod and extends into the guide groove of the guide frame for sliding engagement.

[0012] In summary, the technical effects and advantages of this utility model are as follows: This invention features an arch-breaking mechanism consisting of a drive unit, connecting rods, and multiple accelerator rods. First, the multiple accelerator rods act like multiple "hands," poking, inserting, and stirring the material at different positions and times. Their movement covers the entire hopper cross-section, eliminating dead zones in the mixing process. Second, the staggered movement avoids the overall material resonance compaction that might occur when all rods move synchronously. Instead, it creates continuous and interlaced shearing and impact forces on the slab material layer, more effectively breaking down the mechanical balance of the "arch bridge" structure. Furthermore, the guide head designed at the top of the accelerator rods retracts to reduce resistance and penetrate deeper into the material when moving upwards; it unfolds like a "barb" when moving downwards, hooking and pulling the slab blocks above downwards to break them off. This achieves active arch breaking from top to bottom, fundamentally solving the overhead problem caused by relying solely on the bottom auger and ensuring continuous and smooth material flow.

[0013] This invention, due to the staggered arrangement of adjacent eccentric rods, creates a complex flow field inside the hopper through the staggered movement of the feeding rod. The asynchronous up-and-down reciprocating motion not only breaks up large, hardened pieces of feed but also thoroughly agitates and mixes the material as it falls. Simultaneously, as the falling material passes the position of the eccentric rod, the staggered eccentric rod effectively breaks up and agitates the material during its rotation, preventing the segregation and stratification of different components in the feed caused by static placement. This ensures the uniformity of feed composition for each feeding, which is beneficial to the health and balanced nutritional intake of livestock and poultry. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 1-5 An automatic feeding device for livestock farming includes a mounting frame 1, which serves as the support structure for the entire device. A hopper 2 for storing mixed feed is fixedly installed on the upper part of the hopper 1. The bottom of the hopper 2 is provided with a discharge port for the final feeding of feed. An openable and closable feed blocking mechanism is provided at the discharge port to control the flow of feed. A feed trough 3 is provided directly below the hopper 2 to receive and feed the livestock.

[0019] The hopper 2 is equipped with an arch-breaking mechanism. The main function of the arch-breaking mechanism is to break up the bridging and arching caused by the standing of watery feed, so as to ensure smooth feeding. The arch-breaking mechanism includes a drive component 4, a drive motor 5, at least two feeding rods 6, and a connecting rod 10. The drive motor 5 is fixedly installed on the outer wall of the hopper 2. The output shaft of the drive motor 5 is connected to the drive component 4 to provide it with rotational power. The drive component 4 specifically includes at least three coaxially arranged connecting rings 41. The connecting rings 41 are arranged in parallel in space. Two adjacent connecting rings 41 are fixedly connected by an eccentrically arranged eccentric rod 42, so that these connecting rings 41 and eccentric rods 42 form an integral rotor structure with multiple eccentric points. Each eccentric rod 42 is uniformly staggered along the circumference of the connecting ring 41. With three connecting rings 41 and two eccentric rods 42, the two eccentric rods 42 are 180 degrees apart in the circumferential position.

[0020] Reference Figure 2-4 Each accelerator rod 6 is vertically arranged and distributed horizontally in the hopper 2, thus covering a large effective area. The bottom of each accelerator rod 6 is connected to the corresponding eccentric rod 42 via a connecting rod 10. Specifically, one end of the connecting rod 10 is rotatably connected to the eccentric rod 42, and the other end is rotatably connected to the bottom of the accelerator rod 6. In this way, when the drive motor 5 drives the drive component 4 to rotate, each eccentric rod 42 will make a circular motion, which in turn drives the accelerator rod 6 connected to it to make a reciprocating up and down motion through the connecting rod 10. Since each eccentric rod 42 is circumferentially staggered, the motion phase of each accelerator rod 6 is different at the same time. Some are rising, and some are falling. The staggered motion mode can form complex and efficient shearing and impact forces inside the hopper 2, which greatly enhances the crushing effect on the caking material, while avoiding the overall compaction of the material that may be caused by synchronous motion.

[0021] To ensure that the feeding rod 6 strictly reciprocates up and down without twisting, a limiting rod 8 is also fixed horizontally inside the hopper 2. Each feeding rod 6 has a limiting slide 9 in the middle. The limiting rod 8 passes through the limiting slide 9 on the feeding rod 6 and forms a sliding fit with it, so that the feeding rod 6 can only slide up and down along the guide of the limiting rod 8 under the drive of the connecting rod 10.

[0022] Reference Figure 2-4 Each feeding rod 6 has a guide rod 7 at its top. The guide rod 7 includes two symmetrically arranged side plates 71. The tops of the two side plates 71 are rotatably connected to the top of the feeding rod 6 via hinges. Due to the certain volume and structure of the side plates 71, even at the minimum deflection angle, there will still be an angle between the side plates 71 and the feeding rod 6 in the natural state, preventing them from completely closing together. This gives the guide rod 7 unidirectional passage. When the feeding rod 6 moves upward, the side plates 71 are subjected to the pressure of the material above and tend to close towards the feeding rod 6, effectively reducing the upward resistance. However, due to the existence of the minimum deflection angle, when the feeding rod 6 moves downward, the side plates 71 will expand outward under the action of material resistance, like a barb, which can hook and forcibly pull the slab above, causing it to collapse downward, thus achieving efficient arch breaking circulation.

[0023] Since the drive unit 4 is located below the feed rod 6, the falling material will be agitated by the eccentric rod 42 on the drive unit 4. The eccentric rod 42 is staggered, so the eccentric rod 42 effectively crushes and agitates the material during rotation, preventing the segregation and stratification of different components in the feed due to standing, and ensuring the uniformity of the feed composition each time it is fed.

[0024] Reference Figure 1 , Figure 2 and Figure 5 The material blocking mechanism includes two arc-shaped baffles 11, two connecting rods 12, and a control component. The arc-shaped contours of the two arc-shaped baffles 11 are precisely fitted with the arc-shaped inner wall of the discharge port of the hopper 2 to ensure the sealing when closed and prevent leakage of wet feed. A connecting rod 12 is fixedly connected to the side of each arc-shaped baffle 11. The other end of the connecting rod 12 is rotatably connected to the side wall of the hopper 2, so that the connecting rod 12 can rotate around its axis, thereby driving the arc-shaped baffle 11 to open and close.

[0025] The control assembly is used to synchronously drive the two connecting rods 12 to rotate. It includes a drive cylinder 13, a guide frame 14, and a guide post 15 fixed to the connecting rods 12. The drive cylinder 13 is fixedly installed on the outer wall of the hopper 2. The end of the piston rod of the drive cylinder 13 is fixedly connected to the guide frame 14. A horizontal guide groove is provided on the guide frame 14. The guide post 15 is fixed to the connecting rod 12 and extends into the horizontal guide groove of the guide frame 14 to form a sliding fit. When it is necessary to open the arc-shaped baffle 11 to feed material, the piston rod of the drive cylinder 13 is pulled back, pulling the guide frame 14 to move upward. The groove wall of the guide groove of the guide frame 14 will drive the guide post 15 to move upward. Since the guide post 15 is fixed to the connecting rod 12, and the connecting rod 12 is hinged to the side wall of the hopper 2, this force can be decomposed into a torque that causes the connecting rod 12 to rotate. Under the constraint and guidance of the guide groove, the connecting rod 12 is driven to rotate around its axis, so as to realize the smooth opening of the two arc-shaped baffles 11. The closing process is the opposite. Throughout the process, the guide groove compensates for the combined lateral and longitudinal displacement of the guide column 15 when the connecting rod 12 rotates, so that the simple linear motion of the cylinder can be perfectly converted into the rotational opening and closing motion of the baffle. The structure is simple and the operation is reliable.

[0026] Working principle: By programming and controlling the drive cylinder 13, timed and quantitative feeding control can be achieved. When feeding is required, the drive cylinder 13 is activated, pulling the guide frame 14 with the guide groove, which forces the guide column 15 fixed to the connecting rod 12 to move accordingly, converting the linear motion of the drive cylinder 13 into the rotation of the connecting rod 12, thereby synchronously driving the two arc-shaped baffles 11 to rotate around the axis and open, allowing the feed to fall into the feed trough 3 below. After feeding is completed, the drive cylinder 13 moves in the opposite direction, pushing the arc-shaped baffles 11 to close tightly.

[0027] During the feeding process, the drive motor 5 starts, driving the drive component 4 to rotate. Through the transmission of the connecting rod 10, the rotational motion is converted into the up-and-down reciprocating motion of multiple feeding rods 6 under the constraint of the limiting rod 8 with phase misalignment. During this process, when the guide rod 7 at the top of the feeding rod 6 rises, its side plate 71 retracts to reduce resistance and penetrates deeper into the material layer; when it descends, the side plate 71 naturally unfolds due to structural interference, like a barb, pulling and breaking up the clumps of material above. At the same time, the feeding rods 6 with misaligned movement and the rotating eccentric rod 42 itself work together to continuously stir, shear and mix the material, fundamentally destroying the arch bridge structure, ensuring the looseness and homogeneity of the feed, so that it can flow smoothly to the discharge port under the action of gravity.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
