Description

Technical Field

[0001] This utility model relates to the field of supplementary feeding pen technology, and in particular to a multifunctional supplementary feeding pen for pre-weaning lambs. Background Technology

[0002] In lamb farming, supplementary feeding pens are open-style feeding structures used to feed lambs. Existing supplementary feeding pens generally use open feed troughs of fixed height. Ewes tend to take advantage of their size to crowd out feeding positions, resulting in insufficient lamb intake and affecting growth and development. In addition, lambs' rooting behavior can easily spill feed outside the trough, making open feed susceptible to contamination. Furthermore, the fixed height of the feeding opening cannot adapt to the body size changes of lambs of different ages, resulting in low feeding efficiency. Although there are existing electric induction anti-stealing feeding devices, they suffer from problems such as dependence on power supply and high maintenance costs. Therefore, there is an urgent need to develop a multifunctional supplementary feeding pen for pre-weaning lambs. Utility Model Content

[0003] The purpose of this invention is to address the deficiencies in the existing technology by proposing a multifunctional supplementary feeding pen for pre-weaning lambs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multi-functional supplementary feeding pen for pre-weaning lambs, comprising:

[0006] The top frame assembly is horizontally fixed to the top of the fence, and vertically extending through-slide support columns are provided on both sides of the top frame assembly;

[0007] A feed container is suspended below the top frame assembly, and the bottom of the feed container is provided with a leakage slit;

[0008] An active opening and closing mechanism is located below the feed container and cooperates with the chute support column;

[0009] The sliding connector is located on both sides of the movable opening and closing mechanism and forms a sliding pair with the sliding support column of the top frame assembly;

[0010] The receiving device is fixed to the ground with its opening facing upwards, and is located directly below the movable opening and closing mechanism.

[0011] The movable opening and closing mechanism closes the material leakage gap under normal conditions through a gravity reset unit. When the lamb lifts the movable opening and closing mechanism, the movable opening and closing mechanism moves vertically along the slide support and opens the material leakage channel.

[0012] Furthermore, the movable opening and closing mechanism includes a horizontal support plate, parallel to the ground and located directly below the feed container;

[0013] The inclined linkage plate extends upward from the rear end of the horizontal support plate.

[0014] Furthermore, the inclined linkage plate and the horizontal support plate are connected at an obtuse angle;

[0015] The gravity reset unit is fixed to the end of the inclined linkage plate by bolts.

[0016] Furthermore, the feed container is provided with several vertical protective fences on its front side;

[0017] The bottom end of the protective fence and the upper surface of the horizontal support plate form a three-dimensional interlaced space;

[0018] The gaps in the protective fence are smaller than the width of the ewe's tongue.

[0019] Furthermore, the protective fence is coupled to the feed container via a slider;

[0020] The slider is equipped with a spring that cooperates with it.

[0021] Furthermore, the material leakage seam has a continuous sawtooth structure with the tips of the teeth facing each other.

[0022] Furthermore, the bottom of the receiving device is provided with anti-scratching protrusions;

[0023] The anti-scratching bumps have a sharp geometric shape with a plum blossom-like distribution on their raised tops.

[0024] Furthermore, the horizontal support plate has an arc-shaped protective edge on the side away from the feed container;

[0025] The curvature of the curved protective edge is adapted to the outline of the lamb's body.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] The three-dimensional interlaced space formed by the vertical protective fence and the horizontal support plate can achieve physical barrier based on the biological characteristics of the ewe's tongue thickness. The anti-picking protrusions can produce pain stimulation on the ewe's hard hooves without harming the lamb's soft hooves, reducing the ewe's picking behavior. The lifting and lowering mechanism of the movable opening and closing mechanism can simultaneously change the height of the bottom of the protective fence to form a movable isolation zone. In addition, the gravity reset unit and the inclined linkage plate can dynamically adjust the opening of the feed leakage gap according to the lamb's pushing force, adapting to the force changes of different parts of the lamb's body at different ages, and can form a centripetal guide to concentrate the feed drop area. During use, no power supply is required, and it is suitable for different material flow rates. Attached Figure Description

[0036] Reference Figure 1-4 A multi-functional supplementary feeding pen for pre-weaning lambs, including:

[0037] The top frame assembly 1 is horizontally fixed to the top of the fence, and the top frame assembly 1 has vertically extending through groove support columns 11 on both sides.

[0038] Feed container 2 is suspended below the top frame assembly 1, and the bottom of the feed container 2 is provided with a leakage slit 21;

[0039] The movable opening and closing mechanism 3 is located below the feed container 2 and cooperates with the chute support column 11;

[0040] The sliding connector 31 is disposed on both sides of the movable opening and closing mechanism 3 and forms a sliding pair with the sliding support column 11 of the top frame assembly 1;

[0041] The receiving device 4 is fixed to the ground with its opening facing upwards, and is located directly below the movable opening and closing mechanism 3.

[0042] The movable opening and closing mechanism 3, under normal conditions, closes the feed leakage slit 21 via a gravity reset unit 32. When a lamb lifts the movable opening and closing mechanism 3, the mechanism moves vertically along the chute support 11 and opens the feed leakage channel. In one specific implementation, the top frame assembly 1 is horizontally welded to the sheep pen fence, with the two chute support columns 11 running vertically through it. The feed container 2 is suspended directly below the top frame assembly 1 by a hanger, and its bottom plate is inclined and has a feed leakage slit 21. The movable opening and closing mechanism 3 is connected by sliding connectors 3 on both sides. 1. In this embodiment, a connecting block with rollers is embedded in the chute support column 11, the receiving device 4 is fixed on the ground, the chute opening is directly below the leakage gap 21, and the gravity reset unit 32 makes the movable opening and closing mechanism 3 fit tightly against the bottom of the feed container 2 when it is stationary, thus sealing the leakage gap 21. When the lamb pushes up the movable opening and closing mechanism 3, the mechanism moves vertically upward along the chute support column 11, and a gap is formed between the leakage gap 21 and the movable opening and closing mechanism 3. The feed falls into the receiving device 4 due to gravity. After the lamb stops pushing, the gravity reset unit 32 pulls the mechanism to reset and close.

[0043] The movable opening and closing mechanism 3 includes a horizontal support plate 33, which is parallel to the ground and located directly below the feed container 2;

[0044] The inclined linkage plate 34 extends upward from the rear end of the horizontal support plate 33.

[0045] The inclined linkage plate 34 and the horizontal support plate 33 are connected at an obtuse angle.

[0046] The gravity reset unit 32 is fixed to the end of the inclined linkage plate 34 by bolts 321. In one specific embodiment, the front end of the horizontal support plate 33 extends to the outer edge of the feed container 2. The inclined linkage plate 34 and the horizontal support plate 33 form an obtuse angle through a bending process. The end is welded with a counterweight box as the gravity reset unit 32. The box is filled with metal blocks of adjustable weight and fixed by bolts 321. The inclined linkage plate 34 constitutes a force-saving lever. The torque generated by the counterweight block is transmitted to the horizontal support plate 33 through the plate body, so that it generates an upward pushing pressure. When the lamb pushes the horizontal support plate 33, the lever effect makes the actual pushing force required less than the total weight of the counterweight block, thus achieving lightweight operation.

[0047] The feed container 2 is provided with several vertical protective fences 22 on its front side;

[0048] The bottom end of the protective fence 22 and the upper surface of the horizontal support plate 33 form a three-dimensional interlaced space;

[0049] The gaps in the protective fence 22 are smaller than the width of the ewe's tongue.

[0050] The protective fence 22 is engaged with the feed container 2 via a slider 221;

[0051] The slider 221 is equipped with a spring that cooperates with it. In one specific embodiment, several round steel bars are welded at intervals on the front of the feed container 2 as protective fences 22. Each protective fence is inserted into the vertical slide of the container side wall through the T-shaped slider 221. A compression spring is installed on the top of the slider 221 to provide buffering and reset functions. The protective fences 22 and the horizontal support plate 33 form an interlaced space. The ewe's tongue cannot be inserted because its thickness is greater than the gap of the protective fences 22. When the movable opening and closing mechanism 3 moves up and down, the spring causes the protective fences 22 to rise and fall slightly to avoid the mechanism from jamming.

[0052] The material leakage slit 21 has a continuous sawtooth structure with the tips of the teeth facing each other.

[0053] The bottom of the receiving device 4 is provided with an anti-scraping protrusion 41;

[0054] The top of the anti-scratching protrusion 41 has a sharp geometric shape distributed in a plum blossom pattern.

[0055] The horizontal support plate 33 is provided with an arc-shaped protective edge 331 on the side away from the feed container 2;

[0056] The curvature of the arc-shaped protective edge 331 is adapted to the outline of the lamb's head. In a specific implementation, the feed leakage seam 21 is laser-cut to form a wavy sawtooth pattern. The bottom of the receiving device 4 is stamped with a triangular cone-shaped anti-pickup protrusion 41. The alternating tips of the sawtooth feed leakage seam 21 can break up clumps of feed during the feeding process to prevent blockage. The tips of the relatively inward-pointing teeth form a material guide, causing the feed to fall into the receiving trough in a concentrated manner. The sharp top of the anti-pickup protrusion 41 causes a stinging sensation to the hard hooves of the ewe, while the lamb's soft hooves do not experience any obvious discomfort when in contact with it.

[0057] The front edge of the horizontal support plate 33 is rolled into an arc-shaped protective edge 331. The radius of curvature of the arc matches the curvature of the lamb's body. When the lamb pushes, the smooth surface of the arc-shaped protective edge 331 avoids scratching the skin. Its bending angle limits the lamb's head from extending too far under the mechanism to prevent neck sprains. The silicone layer increases the coefficient of friction and improves the stability of the pushing operation.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. 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.
