Abstract
Description

[0002] Traditional breeding pens are all provided with windows for livestock to eat. It is a common breeding management method, which can provide convenient feeding opportunities and control the feed intake at the same time. The size of the window should be adapted to the volume of the livestock, especially the head and neck of the livestock can freely pass through the window.
[0003] However, at present, it is generally batch - bred according to birth. This method usually separates animals in different production cycles for breeding and management in order to more effectively control the production process. This will lead to livestock with fast growth rates, such as sheep and pigs, needing to frequently change the windows of the breeding pen. However, the windows of traditional breeding pens are fixed and cannot be adjusted, so the breeding places of the livestock need to be changed.
[0004] Moreover, in order to improve the stability of traditional breeding pens, multiple railings are usually welded together by welding. Once the breeding pen is fixed by welding, it is difficult to make changes or adjustments to it, such as adjusting the height or layout of the railings. This limits the flexibility of the pen, especially in cases where it is necessary to adapt to different animals or different breeding environments. Summary of the Utility Model

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0032] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0033] Example 1
[0034] Reference Figures 1 to 3 , which is the first embodiment of the utility model. This embodiment provides an adjustment mechanism, which can quickly widen or narrow the window for livestock to eat. The width of the window can be adjusted according to the size and type of livestock. It includes: brackets 102 are respectively arranged at the upper and lower ends between the two support columns 101, and an adjustment rod 103 is arranged at the central axis position of the bracket 102 at the upper and lower positions between the two support columns 101. The vertical rod 104 fixes the two groups of brackets 102 and the adjustment rod 103 together. The mouth-shaped frame formed by the support column 101, the adjustment rod 103, the vertical rod 104 and the bracket 102 located at the lower side is the window for livestock to eat. The livestock needs to put its head through the window to eat.
[0035] Specifically, an annular groove 201a is formed on the outer surface of the adjusting rod 103. An annular rotating seat 201b is rotatably connected in the annular groove 201a. An active rod 201c is fixedly connected to the outer part of the rotating seat 201b. The length of the active rod 201c is equal to the distance between the adjusting rod 103 and the bracket 102. The design of the annular groove 201a and the rotating seat 201b enables the rotating seat 201b to rotate on the adjusting rod 103, thereby changing the position or angle of the active rod 201c.
[0036] Among them, a semi-circular rotating groove 202a is formed in the active rod 201c. Connecting rods 202b are fixedly connected to both sides of the inner wall of the rotating groove 202a. The connecting rods 202b are in a "T" shape. A fixed seat 202c is rotatably connected between the two groups of connecting rods 202b. The "T"-shaped connecting rods 202b can effectively connect the fixed seat 202c in the rotating groove 202a, preventing excessive shaking or tilting during its rotation. And this structure can ensure that the fixed seat 202c remains stable during rotation, making its rotation smoother and more controllable. The outer wall of the fixed seat 202c is beveled near one side, ensuring that the fixed seat 202c can move smoothly in the rotating groove 202a during rotation, without getting stuck or causing unsmooth rotation due to the contact between the outer wall and the inner wall of the rotating groove 202a.
[0037] Further, semi-circular grooves 203a are formed in the front positions on the outer parts of the two brackets 102. The positions of the grooves 203a are adapted to the annular groove 201a on the adjusting rod 103 and are also adapted to the active rod 201c. Cylindrical limit posts 203b are arranged in the grooves 203a. A limit groove 203c is arranged on one side surface of the fixed seat 202c. The limit groove 203c cooperates with the limit posts 203b. When the active rod 201c is rotated clockwise, the notch of the limit groove 203c of the fixed seat 202c faces backward. When the active rod 201c is in a vertical state, the fixed seat 202c will be limited in the groove 203a and the limit groove 203c of the fixed seat 202c is sleeved outside the limit posts 203b. At this time, the feeding window for livestock will be separated into two small windows by the active rod 201c. On the contrary, when the active rod 201c is rotated counterclockwise and the limit groove 203c on the fixed seat 202c is sleeved on the limit posts 203b in the groove 203a of the upper bracket 102, the two small windows will be combined into a large window, which can be suitable for the volumes of livestock in different periods. Similarly, a plurality of active rods 201c can be arranged on the adjusting rod 103 to divide the feeding window into several small windows, and then the position of the active rod 201c can be adjusted according to the actual head width of the livestock.
[0038] Embodiment 2
[0039] Refer toFigure 2 and Figure 5 This is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a locking unit 300 for the adjusting mechanism, which solves the problem that the fixing seat 202c will be separated from the limiting column 203b when the movable rod 201c is pushed by an external force. It includes two semi-circular storage grooves 301a opened on the outer side of the limiting column 203b. The two storage grooves 301a are arranged in axial mirror symmetry. At the bottom of the inner walls of the two storage grooves 301a, circular lifting grooves 302a are opened at the central position. Lifting blocks 302b are movably connected in the two lifting grooves 302a. On the outer side of the lifting blocks 302b, limiting blocks 301b matching the storage grooves 301a are provided. On the inner wall of the limiting groove 203c, arc-shaped grooves 301c are arranged in mirror symmetry. The positions and specifications of the arc-shaped grooves 301c match those of the limiting blocks 301b.
[0040] Among them, an extrusion groove 303b is opened on one side of the lifting groove 302a, and a displacement groove 303a is opened on the other side of the lifting groove 302a. A special-shaped block 302d is horizontally movably connected in the displacement groove 303a. The special-shaped block 302d is an equilateral quadrilateral. A pair of special-shaped blocks 302d are arranged in mirror symmetry on the upper and lower sides in the displacement groove 303a. The other sides of the two special-shaped blocks 302d are fixedly connected together. And a special-shaped groove 302c is opened in the lifting block 302b. The special-shaped groove 302c matches the special-shaped block 302d. The upper and lower surfaces of the special-shaped groove 302c are inclined planes and are parallel to each other. This makes it that when the special-shaped block 302d horizontally displaces in one direction, the lower inclined plane of the special-shaped block 302d will apply a pushing force in one direction to the lower inclined plane of the special-shaped groove 302c. Since the lifting block 302b is movably connected in the lifting groove 302a, and the lifting block 302b and the lifting groove 302a are adapted and closely fitted, the position of the lifting block 302b is restricted and can only move vertically up and down. This makes the lifting block 302b move vertically downward under the push of the special-shaped block 302d. On the contrary, when the special-shaped block 302d moves in the other direction, the lifting block 302b moves vertically upward.
[0041] Furthermore, a spring 303c is fixedly connected to the bottom of the extrusion groove 303b, and a push plate 303d is fixedly connected to the other end of the spring 303c. Under the action of the stretching elastic force of the spring 303c, the other side of the push plate 303d always fits the surface of one side of the special-shaped block 302d. A limiting annular groove 304b is provided on the other side surface of the fixed seat 202c. An annular plate 304c is horizontally movable in the limiting annular groove 304b. The width of the annular plate 304c is consistent with that of the limiting annular groove 304b. A pressing piece 304d is fixedly connected to the other side of the annular plate 304c. However, the width of the pressing piece 304d is smaller than that of the annular plate 304c, which allows the pressing piece 304d to slide freely and be connected in the limiting ring groove 304b, but the annular plate 304c cannot be separated from the limiting ring groove 304b. A cylindrical pushing rod 304e is fixedly connected to the center position of the inner wall of the pressing piece 304d. The pushing rod 304e passes through the fixed seat 202c, and a circular hole 304a is opened on the other side surface of the limiting column 203b. The circular hole 304a is connected to the displacement groove 303a, and the diameter of the circular hole 304a is larger than the diameter of the pushing rod 304e.
[0042] When the movable rod 201c is in use, the limit position of the rotating movable rod 201c cannot fit into the groove 203a, and the lifting rod 301c is pushed by the special-shaped block 302d to move outward, thereby driving the limit block 301b to protrude outward from the inside of the storage groove 301a. The edge of the limit groove 203c on one side of the fixed seat 202c is blocked by the protruding limit block 301b and cannot be sleeved on the limit column 203b. At this time, we can press the pressing piece 304d on the other side, and the pressing piece 304d will slide to one side in the limiting ring groove 304b, and the pushing rod 304e, under the push of the pressing piece 304d, passes through the circular hole 304a and contacts the special-shaped block 302d, and pushes the special-shaped block 302d to move to one side, applying pressure to the pushing plate 303d in the direction of one side, causing the spring 303c to contract, storing elastic potential energy, and the special-shaped block 302d pushes the upper and lower The lifting block 302b on the side moves inward at the same time, and the limiting block 301b is limited in the storage groove 301a. At this time, the movable rod 201c can be rotated continuously to be connected to the outside of the limiting column 203b without obstruction. At this time, the pressing piece 304d can be released, and under the action of the extended elastic force of the spring 303c, a push is applied to the other side. Under the push of the pushing plate 303d, the special-shaped block 302d moves quickly, and drives the lifting blocks 302b on the upper and lower sides to move quickly outward, pushing the limiting block 301b to limit the arc groove 301c, achieving the effect of locking the limiting column 203b and the limiting groove 203c together, so that the movable rod 201c can be firmly fixed on the bracket 102. On the contrary, when the window at this time cannot meet the width of the livestock head, one of the rotating rods can be unlocked and reversed and fixed on the bracket 102 on the upper side.
[0043] Example 3
[0044] Reference Figures 6 to 7 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a prefabricated livestock breeding pen, which solves the problem that it is difficult to modify or adjust the breeding pen when it is fixed by welding. It includes the adjusting mechanism in the above embodiment, including a fixed rod 401, a connection hole 402 provided on the support column 101, the connection hole 402 is threadedly connected to the fixed rod 401, a connection component 403 provided in the connection hole 402 and cooperating with the fixed rod 401, and the connection component 403 is respectively connected to the bracket 102 and the adjusting rod 103.
[0045] Specifically, connection pieces 403b are fixedly connected to both ends of the bracket 102 and the adjusting rod 103. The connection pieces 403b at both ends are arranged staggeredly, that is, one side of the connection piece 403b is close to the lower position, and the connection piece 403b on the other side is close to the upper position. Three groups of connection grooves 403a are provided on the support column 101. One group of connection grooves 403a is provided on both side surfaces of the support column 101, which is also arranged staggeredly. This enables two brackets 102 and one adjusting rod 103 to be respectively arranged on both sides of a connection column, achieving the effect of layout of the breeding farm according to needs;
[0046] Among them, a cylindrical connection hole 402 is provided at the center position of the support column 101. A fixed rod 401 is threadedly connected in the connection hole 402. The external thread of the fixed rod 401 is provided at the outer part near the lower end position, and the internal thread of the connection hole 402 is also provided at the inner part near the bottom position. Circular through holes 403c are provided on several connection pieces 403b. The diameter of the through hole 403c is equivalent to that of the connection hole 402. When the connection pieces 403b of the bracket 102 and the adjusting rod 103 are inserted into the connection groove 403a, and the end surfaces of the bracket 102 and the adjusting rod 103 are in contact with the surface of the support column 101, at this time, the through hole 403c on the connection piece 403b is aligned with the connection hole 402. At this time, the fixed rod 401 can be inserted into the connection hole 402 and pass through the through hole 403c. At this time, the connection piece 403b cannot be removed, which achieves the effect of fixedly connecting the bracket 102 or the adjusting rod 103 and the support column 101 together. After the fixed rod 401 and the connection hole 402 are threadedly connected together, the stability of the device is further improved. And only by reversing the fixed rod 401 and pulling out the fixed rod 401, the disassembly of the bracket 102 or the adjusting rod 103 and the support column 101 can be realized, and both installation and disassembly are very convenient.
