Description

Technical Field

[0001] The utility model relates to the technical field of animal husbandry, in particular to a cattle blood sampling fixing frame. Background Art

[0002] In the process of raising cattle, in addition to daily feeding, cattle also need to be treated and blood drawn. The blood drawing location is generally the neck, tail or leg. In the breeding farm, cattle neck shackles have been popularized for feeding. Generally, cattle neck shackles include multiple vertical rods and a rotating inclined rod. The inclined rod relies on gravity to tilt. When the cow's head passes through the cow neck shackle and lowers its head to eat, the inclined rod of the cow neck shackle automatically stands up and locks. The cow neck shackle forms a clamping limit on the cow's neck in the left and right and front and back directions, reducing the walking and grabbing of food between cattle. At the same time, the cow neck shackle can also be used to fix the cow's head when drawing blood from the cow, but the commonly used cow neck shackle has a poor effect on the upper and lower limit, and cannot adapt well to the more stable restriction and fixation of the cow's head during blood collection. Although there are also wrapped cow neck shackles that can restrict the cow's head in all directions, the overall modification cost is large, and its adjustment adaptability to different cows is poor. At present, there is a lack of equipment that can adapt to the traditional cow neck shackle to restrict and fix the cow's head. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a cattle blood collection fixing frame for the above-mentioned technical deficiencies, which can be adapted to the existing traditional cattle neck yoke for use, has low modification cost, can well restrict and fix the cattle head, and is convenient for blood collection operations on cattle.

[0005] A limit plate is slidably arranged on the cattle neck yoke along the up-down direction, and the limit plate has a first connection part and a second connection part, and the first connection part and the second connection part are respectively located on two sides of the limit plate;

[0006] A first half hoop is connected to the first connecting portion through a connecting piece, the first half hoop and the first connecting portion are combined to form a first hoop, and the first hoop is used for slidingly sleeved on the cattle yoke;

[0007] The second half hoop is connected to the second connecting part through a connecting piece. The second half hoop and the second connecting part are combined to form a second hoop. The second hoop is used for slidingly sleeved on the cattle yoke.

[0008] To further optimize the technical solution, the first connecting portion has a connecting hole, which is used to connect with the first half hoop; the second connecting portion has a strip hole, which is used to connect with the second half hoop.

[0009] To further optimize the technical solution, the two neck clamping devices are relatively movable; and further include:

[0010] The adjusting screw is rotationally connected to one of the first half clamps and is threadedly connected to the other first half clamp.

[0011] Further optimization of this technical solution also includes:

[0012] A protective pad is arranged on the limiting plate and is used for contacting with the cow's neck.

[0013] Further optimizing the technical solution, it also includes a positioning device for positioning the limit plate, and the positioning device includes:

[0014] A positioning block, detachably arranged on the cattle neck yoke;

[0015] A positioning plate is slidably arranged on the positioning block. After sliding, the positioning plate moves closer to or farther from the limiting plate. The positioning plate is used to abut against the upper end of the limiting plate.

[0016] To further optimize the technical solution, the positioning device further includes:

[0017] A third half hoop is connected to the positioning block through a connecting piece, the third half hoop and the positioning block form a third hoop, and the third hoop is used to be mounted on the cattle yoke;

[0018] A support plate is arranged on the third half clamp and is used for abutting against the lower end of the limiting plate.

[0019] To further optimize the technical solution, the end of the positioning plate close to the limiting plate has an inclined guiding slope, and the positioning device further includes:

[0020] A return compression spring, one end of which acts on the positioning block and the other end of which acts on the positioning plate, is used to provide elastic force for the positioning plate to slide close to the limiting plate.

[0021] To further optimize the technical solution, the positioning plate is "U"-shaped, and the upper portion of the positioning block has a sliding groove that slidably cooperates with the positioning plate.

[0022] To further optimize the technical solution, the first clamp and the second clamp are clearance-matched with the cattle yoke, and the third clamp is used to clamp the cattle yoke.

[0023] To further optimize the technical solution, the cattle yoke includes four vertical rods, which are respectively a first vertical rod, a second vertical rod, a third vertical rod and a fourth vertical rod, the first hoop is arranged on the outside of the first vertical rod, the second hoop is arranged on the outside of the fourth vertical rod, and the third hoop is arranged on the second vertical rod or the third vertical rod.

[0024] The beneficial effects of the utility model are:

[0025] 1. The first half hoop and the first connecting part, the second half hoop and the second connecting part are all in the form of hoops, which are easy to disassemble and assemble. They can be installed based on the existing cattle shackles in the breeding farm, reducing the cost of transformation and use.

[0026] 2. Two neck clamps are set up, and the cow's head passes through the two neck clamps. The two neck clamps move synchronously. When the cow lowers its head to eat, triggering the cow's neck yoke to clamp, the two neck clamps are driven down at the same time. When the cow's head moves up and down, it is restricted by the neck clamps. The neck clamps can rely on friction resistance to hinder the up and down movement of the limit plate, thereby slowing down the up and down movement of the cow's head. The limit plate can also be pressed and positioned by people. When the cow's head moves up and down, especially when it wants to get out of the cow's neck yoke, it also applies a lateral force to the limit plate, not a single up and down force, so the up and down movement of the limit plate is restricted.

DETAILED DESCRIPTION

[0036] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] In order to simplify the drawings, only the parts related to the utility model are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0038] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0039] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0040] like Figure 1 As shown, a conventional cattle neck yoke 1 is shown (only part of the structure is shown and marked), the cattle neck yoke 1 includes a first vertical rod 101, a second vertical rod 102, a third vertical rod 103 and a fourth vertical rod 104, and a rotatable inclined rod 105 in the middle. The installation structure of the fixing frame is described by taking the cattle neck yoke 1 as an example, and other similar cattle neck yokes 1 can be used. The distinction of the vertical rods is only for the convenience of description, and does not limit the specific number and form. The vertical rods are the installation positions of the fixing frame on the cattle neck yoke 1.

[0041] like Figure 1-8 As shown, the cattle blood collection fixing frame includes: a neck clamping device 2, which has two, the two neck clamping devices 2 are spaced apart from each other, the neck clamping device 2 is slidably arranged on the cattle neck yoke 1 along the up-down direction, and the two neck clamping devices 2 move synchronously, and the neck clamping device 2 includes: a limit plate 201, which is slidably arranged on the cattle neck yoke 1 along the up-down direction, and the limit plate 201 has a first connecting portion 2011 and a second connecting portion 2013, and the first connecting portion 2011 and the second connecting portion 2013 are respectively located on both sides of the limit plate 201 The first half hoop 202 is connected to the first connecting part 2011 through the connecting piece 204, and the first half hoop 202 and the first connecting part 2011 are combined to form the first hoop 203, and the first hoop 203 is used to be slidably mounted on the cattle yoke 1; the second half hoop 205 is connected to the second connecting part 2013 through the connecting piece 204, and the second half hoop 205 and the second connecting part 2013 are combined to form the second hoop 206, and the second hoop 206 is used to be slidably mounted on the cattle yoke 1.

[0042] When in use, the limiting plate 201 is located at the rear side of the cattle neck yoke 1 (the side close to the cattle is the rear side), the first half hoop 202 and the first connecting part 2011 form a first hoop 203, the first hoop 203 can be mounted on the outside of the first vertical rod 101, and the second hoop 206 can be mounted on the fourth vertical rod 104. Through clearance fit, the clamping device can be installed on the cattle neck yoke 1, and can slide up and down at the same time. The clearance can be set small to facilitate following the movement of the cattle head. At the same time, when the cattle head applies force in the front and rear directions to the clamping neck device 2, the friction between the hoop structure and the vertical rod is increased, which plays a better limiting role.

[0043] like Figure 3 As shown, the bull's head enters between the two limit plates 201 and moves downward to trigger the inclined rod 105 of the bull's neck yoke 1. After the inclined rod 105 is erected, the bull's head is restricted in the left and right directions and the front and back directions. The neck clamping device 2 restricts the bull's head in the up and down directions.

[0044] The first half clamp 202 and the second half clamp 205 may be arc-shaped, and the connecting piece 204 may be a structure such as bolts and nuts. Those skilled in the art may realize various connection forms.

[0045] Furthermore, the first connection portion 2011 has a connection hole 2012 , and the connection hole 2012 is used to connect with the first half hoop 202 ; the second connection portion 2013 has a strip hole 2014 , and the strip hole 2014 is used to connect with the second half hoop 205 .

[0046] When in use, the first connection part 2011 can be provided with two connection holes 2012 for connecting with the first half hoop 202, and the strip hole 2014 of the second connection part 2013 can be longer in length to facilitate adapting to vertical rods arranged at different intervals, and has strong installation adaptability. The position of the strip hole 2014 is opposite to the position of the fourth vertical rod 104, and the length is greater than the length of the second half hoop 205.

[0047] Furthermore, the two neck clamping devices 2 are arranged to move relative to each other; and further include: an adjusting screw 3, which is rotationally connected to one of the first half clamps 202 and is threadedly connected to the other first half clamp 202.

[0048] When in use, the two neck clamping devices 2 move up and down synchronously relative to the cow neck yoke 1, and can follow the movement of the cow's head. The two neck clamping devices 2 can move relative to each other, which is convenient for adjusting the interval between the two limit plates 201 and can adapt to different cow head sizes. The adjusting screw 3 can be rotatably connected to the first half clamping hoop 202 on the lower side at the lower end, and the upper end is threadedly connected to the first half clamping hoop 202 on the upper side. The interval between the two limit plates 201 can be adjusted by rotation, and it has good self-locking ability. After locking, the two limit plates 201 move synchronously.

[0049] There may be two adjusting screws 3, which are used to adjust the distance between the two first half hoops 202 and the distance between the two second half hoops 205 respectively, which is more stable.

[0050] Furthermore, it also includes: a protection pad 4, which is arranged on the limiting plate 201 and is used to abut against the cow's neck.

[0051] When in use, the upper and lower limit plates 201 are in contact with the cow's neck. Adding the protective pad 4 can improve the comfort of the contact area and reduce the scratches and crushing of the cow's neck by the steel plate. The protective pad 4 can be set on one or both limit plates 201, and can be in a wrapped form or a semi-enclosed plug-in installation form. At the same time, it can be fixed with bolts for easy disassembly and assembly. The part where the protective pad 4 contacts the cow's neck can be made of rubber.

[0052] Furthermore, it also includes a positioning device 5 for positioning the limit plate 201. The positioning device 5 includes: a positioning block 501, which is detachably arranged on the cattle neck yoke 1; a locking plate 502, which is slidably arranged on the positioning block 501. After sliding, the locking plate 502 moves closer to or away from the limit plate 201. The locking plate 502 is used to abut against the upper end of the limit plate 201.

[0053] When in use, the positioning device 5 can realize the positioning restriction of the limit plate 201, without manually applying force to fix the limit plate 201. The positioning block 501 can be detachably set on the cattle neck yoke 1, for example, it can be set on the third vertical rod 103, and there are fewer restrictions when adjusting the position up and down, and the adjustment range is wide and convenient. The positioning plate 502 is slidably set on the positioning block 501. When the two clamping neck devices 2 move to the bottom, the positioning plate 502 can move to the upper end of the limit plate 201, hindering the limit plate 201 from moving up, and can limit the up and down movement of the cattle head. After completing the blood collection operation, move the positioning plate 502 away from the limit plate 201, and when the inclined rod 105 of the cattle neck yoke 1 is also released, the cattle head can move up and leave the cattle neck yoke 1.

[0054] The limit plate 201 is opposite to the cow's neck, and the upper and lower limits of the cow's head are limited to a small range of movement, reducing the upper and lower distances that the cow's head can move. At the same time, it can assist in fixing the cow's head with a cow's head cover, and with the fixing frame, the original force used to cover the cow's head can be reduced. When the cow's head exerts force, it generally moves upward, so it is sufficient to have a good upward limit.

[0055] Furthermore, the positioning device 5 also includes: a third half hoop 503, which is connected to the positioning block 501 through a connecting piece 204, the third half hoop 503 and the positioning block 501 form a third hoop 504, and the third hoop 504 is used to be mounted on the cattle yoke 1; a support plate 505, which is arranged on the third half hoop 503 and is used to abut against the lower end of the limiting plate 201.

[0056] When in use, the detachable structure of the positioning block 501 can also adopt a clamp structure, and the third clamp 504 is formed by the third half clamp 503 and the positioning block 501. The third clamp 504 can be clamped on the third vertical rod 103. The position of the positioning block 501 determines the position of the limit plate 201. In addition to limiting the two neck clamping devices 2 at the bottom as mentioned above, the neck clamping device 2 can also be positioned in the middle position or the upper position according to different cows to make the cows more comfortable. For example, the third clamp 504 is used to fix the positioning block 501 in the middle position of the third vertical rod 103, and the positioning device 5 can be located between the two limit plates 201, or below the lower limit plate 201. When the bull head extends between the two limit plates 201, the inclined rod 105 can be manually erected to limit the bull head. The downward movement of the bull head drives the limit plate 201 downward, and the lower end of the lower limit plate 201 abuts against the upper end of the support plate 505. The positioning plate 502 is moved so that the positioning plate 502 abuts against the upper end of the limit plate 201, thereby forming a limit fixation on the upper and lower sides of the limit plate 201, and fixing the neck clamping device 2 in the middle position.

[0057] Furthermore, one end of the locking plate 502 close to the limiting plate 201 has an inclined guiding slope 5021, and the positioning device 5 also includes: a reset compression spring 506, one end of which acts on the positioning block 501 and the other end acts on the locking plate 502, for providing elastic force for the locking plate 502 to slide close to the limiting plate 201.

[0058] When in use, the positioning plate 502 can be pushed and pulled manually, and can also be automatically reset by using the reset spring 506. The rear side of the positioning plate 502 has a guiding inclined surface 5021. When the limiting plate 201 moves downward, the lower end of the limiting plate 201 contacts the guiding inclined surface 5021 and pushes the positioning plate 502 forward, and the reset spring 506 is compressed. Then the positioning plate 502 enters between the support plate 505 and the positioning plate 502, and the reset spring 506 is released, pushing the positioning plate 502 to move to the upper end of the limiting plate 201. When blood sampling is completed, the positioning plate 502 is manually pulled forward to release the limiting plate 201 and move upward.

[0059] Furthermore, the locking plate 502 is “U”-shaped, and the upper portion of the positioning block 501 has a sliding groove 5011 that slidably cooperates with the locking plate 502 .

[0060] When in use, the positioning plate 502 is "U" shaped, with the notch in the middle just opposite to the position of the vertical rod, and the left and right sides of the upper part of the positioning block 501 can be provided with sliding grooves 5011, which can more stably guide the positioning plate 502 in the front and rear directions and simultaneously achieve the upper and lower and left and right direction limit. There can be two return springs 506, which are respectively provided on the left and right sides of the positioning block 501, and the return springs 506 can be fixedly connected to the positioning plate 502 and the positioning block 501.

[0061] Furthermore, the first clamp 203 and the second clamp 206 are clearance-fitted with the cattle yoke 1 , and the third clamp 504 is used to clamp the cattle yoke 1 .

[0062] When in use, the clearance fit facilitates sliding, and the third clamping hoop 504 clamps the cattle neck yoke 1 to facilitate positioning.

[0063] Furthermore, the cattle yoke 1 includes four vertical rods, which are the first vertical rod 101, the second vertical rod 102, the third vertical rod 103 and the fourth vertical rod 104 respectively. The first hoop 203 is sleeved on the outside of the first vertical rod 101, the second hoop 206 is sleeved on the outside of the fourth vertical rod 104, and the third hoop 504 is sleeved on the second vertical rod 102 or the third vertical rod 103.

[0064] When in use, taking the cattle neck yoke 1 with four vertical rods as an example, it can be installed according to the use requirements.
