Description

Technical Field

[0001] This utility model relates to the technical field of livestock equipment, and in particular to a device for fixing the hind limbs of cattle and sheep to prevent kicking during milking. Background Technology

[0002] Cattle and sheep are the main dairy-producing livestock, and anti-kick devices are needed during milking to prevent them from kicking people.

[0003] Chinese utility model patent with publication number CN222736956U discloses an anti-kick device for milking cows. The anti-kick device includes a main body; wherein, the bottom of the main body is provided with universal wheels with brakes, and the top of the main body is a platform for the operator to sit on; a retractable anti-kick component is provided on one side of the main body; during milking operations, the anti-kick component unfolds to limit the cow's hind legs; when not milking, the anti-kick component retracts and is housed inside the main body.

[0004] When in use, the anti-kick limiting rods of the above-mentioned anti-kick device are installed on the main body. The hind legs of cattle and sheep are restricted between the two anti-kick limiting rods. There is no lateral limiting function for the hind legs of cattle and sheep. Moreover, when the hind legs of cattle and sheep kick, the force of their legs is directly applied to the main body through the limiting rods. Because the hind legs of cattle and sheep, especially dairy cows, are very strong, the main body is kicked over, and the staff sitting on the main body will also fall. Therefore, improvements are needed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a safe hind leg fixing device for cattle and sheep milking by limiting the two hind legs to each other, so that the main body will not be brought down when the cattle or sheep kick, thus preventing milking workers from falling.

[0006] This utility model discloses a hind leg restraint device for preventing kicking during cow or sheep milking. It includes a main body and multiple wheels mounted on the bottom of the main body. It also includes a storage chamber, a pipe beam, a first fixing seat, a second fixing seat, a first binding strap, a second binding strap, and a tensioning assembly. The storage chamber on the main body is used to store the pipe beam. The first and second fixing seats are mounted on the side wall of the pipe beam. One end of the first binding strap is connected to the pipe beam, and the other end passes around the first fixing seat and connects to the tensioning assembly. One end of the second binding strap is connected to the pipe beam, and the other end passes around the second fixing seat and connects to the tensioning assembly. The tensioning assembly is mounted on the pipe beam. During operation, the multiple wheels move the main body to the rear of the cow or sheep. The pipe beam is removed from the storage chamber, and the two hind legs of the cow or sheep are inserted between the first fixing seat and the first binding strap, and between the second fixing seat and the second binding strap, respectively. The tensioning assembly is then operated to tighten the binding straps. The other ends of straps 1 and 2 are tightened simultaneously, so that strap 1 and fixed seat 1 work together to secure one hind leg, and strap 2 and fixed seat 2 work together to secure the other hind leg. In this way, the two hind legs of the cow or sheep are mutually restricted. Under normal circumstances, the cow or sheep only uses one hind leg to kick, while the other hind leg supports the body. When the cow or sheep moves, the two hind legs will not move together. Therefore, when the tube beam, fixed seat 1, fixed seat 2, strap 1 and strap 2 restrict the two hind legs to each other, the kicking and lateral movement of the cow or sheep are completely restricted, so that the main body is always outside the range of motion of the hind legs, thus protecting the milking worker sitting on the main body. When one hind leg is kicked, its force is applied to the other hind leg through the tube beam. Since the tube beam is not connected to the main body, the cow or sheep will not bring the main body down when kicking, and the milking worker will not fall. The safety is good.

[0007] Preferably, the tensioning assembly includes a pull rod, multiple ratchet teeth, a limiting rod, and a spring plate. A slot is provided inside the tube beam, and the pull rod is slidably inserted into the slot. Multiple ratchet teeth are provided on the side wall of the pull rod facing away from the fixing seat. The limiting rod is rotatably mounted on the side wall of the tube beam via a pivot. One end of the limiting rod passes through an opening in the side wall of the tube beam and blocks the ratchet teeth outwards. Both ends of the spring plate are connected to the limiting rod and the tube beam, respectively. The elastic force of the spring plate presses one end of the limiting rod against the pull rod. The other ends of straps one and two pass through two slots in the side wall of the tube beam and connect to the pull rod. When straps one and two need to bind the two hind legs, the pull rod is pulled towards the tube beam. The internal push causes the pull rod to bring the other ends of straps one and two closer to the two slots on the tube beam, thus loosening straps one and two to facilitate the fitting of the two rear legs. When straps one and two are fitted over the two rear legs, the pull rod is pulled outwards from the tube beam, causing the pull rod to move the other ends of straps one and two away from the two slots on the tube beam, thus tightening straps one and two. This allows strap one, in conjunction with fixing seat one, and strap two, in conjunction with fixing seat two, to securely bind the two rear legs. At this time, the elasticity of the spring plate presses one end of the limiting rod onto a ratchet, achieving one-way limiting of the pull rod, preventing straps one and two from loosening, and improving the binding effect.

[0008] Preferably, it also includes two locking blocks and two locking slots. The other ends of the first and second straps are each fitted with locking blocks, and the side wall of the pull rod is provided with two locking slots facing the first fixing seat. The two locking blocks are respectively locked into the two locking slots. By providing two locking blocks and two locking slots, it is convenient to quickly install and remove one end of the first strap and one end of the second strap from the pull rod.

[0009] Preferably, it also includes two buffer sleeves, with buffer sleeves installed in the middle of both the first and second binding straps, and the two buffer sleeves are respectively opposite to the first and second fixing seats; by installing two buffer sleeves, the comfort of binding the two hind legs of cattle and sheep is improved.

[0010] Preferably, the assembly also includes two buckles, two hanging rods, two hooks, and two strong magnetic blocks. The two buckles are respectively installed on one end of the first and second binding straps, and hanging rods are installed on both buckles. The two hooks are installed on the side wall of the tube beam, and the two hooks are respectively located on the side of the first and second fixing seats. The two hooks are used to hang the two hanging rods, and the two strong magnetic blocks are respectively installed on the two hooks. The two strong magnetic blocks are used to position and attract the two buckles. The two buckles are placed into the two hooks, so that the two buckles are attracted and positioned by the two strong magnetic blocks, and the two hooks hang the two hanging rods. This facilitates the quick installation and removal of one end of the first and second binding straps from the tube beam. It also facilitates the quick removal of the tube beam from between the two hind legs of cattle and sheep by shaking the tube beam after loosening the first and second binding straps after milking, thereby improving work efficiency.

[0011] Preferably, it also includes a sliding hole seat and a chisel. The sliding hole seat is installed on the side wall of the pipe beam, and the chisel is slidably inserted into the sliding hole seat. After the two hind legs of the cattle and sheep are tied with the first and second binding straps, the chisel is inserted into the ground, so that the chisel and the sliding hole seat fix the pipe beam to a certain extent and improve the limiting effect on the hind legs of the cattle and sheep.

[0012] Preferably, it also includes a first connecting ring, a second connecting ring, a first rope, a second rope, and a buckle. The first connecting ring is installed on the pipe beam, the second connecting ring is installed on the wheel, and the second connecting ring and the first connecting ring are connected by the first rope. One end of the second rope is connected to the first connecting ring, and the other end of the second rope is fitted with a buckle. The pipe beam is flexibly connected to the main body through the first connecting ring, the first rope, and the second connecting ring to prevent the pipe beam from being lost. The pipe beam is connected to the fence or to one of the front legs of cattle or sheep through the first connecting ring, the second rope, and the buckle to further enhance the restraining effect on the hind legs of cattle and sheep and improve the anti-kicking effect.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the tube beam, fixed seat one, fixed seat two, binding strap one and binding strap two limit the two hind legs to each other, the kicking and lateral movement of the cow or sheep are completely restricted, so that the main body is always outside the range of motion of the hind legs, thereby protecting the milking worker sitting on the main body. When one hind leg kicks, its force is applied to the other hind leg through the tube beam. Since the tube beam is not connected to the main body, the cow or sheep will not bring the main body down when kicking, and the milking worker will also be prevented from falling, thus ensuring good safety.

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0022] like Figures 1 to 6As shown, a hind leg restraint device for preventing kicking during milking of cattle and sheep includes a main body 1 and multiple wheels 2, with the wheels 2 mounted on the bottom of the main body 1; it also includes a storage chamber 3, a tube beam 4, a first fixing seat 5, a second fixing seat 6, a first strap 7, a second strap 8, and a tensioning assembly. The storage chamber 3 is provided on the main body 1 to store the tube beam 4. The first fixing seat 5 and the second fixing seat 6 are mounted on the side wall of the tube beam 4. One end of the first strap 7 is connected to the tube beam 4, and the other end of the first strap 7 passes around the first fixing seat 5 and is connected to the tensioning assembly. One end of the second strap 8 is connected to the tube beam 4, and the other end of the second strap 8 passes around the second fixing seat 6 and is connected to the tensioning assembly. The tensioning assembly is mounted on the tube beam 4. The tensioning assembly includes a pull rod 9, multiple ratchet teeth 10, a limiting rod 11, and a spring plate 12. The tube beam 4 has a slot inside, and the pull rod 9 is slidably inserted into the slot of the tube beam 4. Multiple ratchet teeth 10 are provided on the side wall of the pull rod 9 facing away from the fixed seat 5. The limiting rod 11 is rotatably installed on the side wall of the tube beam 4 through a rotating shaft. One end of the limiting rod 11 passes through the opening in the side wall of the tube beam 4 and limits and presses the ratchet teeth 10 to the outside of the tube beam 4. The two ends of the spring plate 12 are respectively connected to the limiting rod 11 and the tube beam 4. The elastic force of the spring plate 12 presses one end of the limiting rod 11 against the pull rod 9. The other ends of the strap 7 and strap 8 pass through the two slots in the side wall of the tube beam 4 and are connected to the pull rod 9. It also includes two buffer sleeves 15. Buffer sleeves 15 are installed in the middle of strap 7 and strap 8. The two buffer sleeves 15 are opposite to the fixed seat 5 and fixed seat 6, respectively.

[0023] During operation, multiple wheels 2 drive the main body 1 to the rear of the cow or sheep, removing the tube beam 4 from the storage chamber 3. The pull rod 9 is pushed inwards towards the tube beam 4, causing it to bring the other ends of straps 7 and 8 closer to the two slots on the tube beam 4, thus loosening them. The cow or sheep's two hind legs are then inserted between the fixing seat 5 and strap 7, and between the fixing seat 6 and strap 8, respectively. The pull rod 9 is then pulled outwards towards the tube beam 4, causing it to move the other ends of straps 7 and 8 away from the two slots on the tube beam 4, thus tightening them. Straps 7, in conjunction with fixing seat 5, and strap 8, in conjunction with fixing seat 6, securely bind the two hind legs. At this point, the spring force of the spring plate 12 presses one end of the limiting rod 11 against a ratchet 10, achieving unidirectional limiting of the pull rod 9 and preventing... The loosening of straps 7 and 8 improves the binding effect. By installing two buffer sleeves 15, the comfort of binding the two hind legs of cattle and sheep is improved. In this way, the two hind legs of cattle or sheep are mutually restricted. Under normal circumstances, cattle or sheep only use one hind leg to kick, while the other hind leg supports the body. When cattle or sheep move, the two hind legs will not move together. Therefore, when the tube beam 4, fixed seat 5, fixed seat 6, strap 7 and strap 8 restrict the two hind legs to each other, the kicking and lateral movement of cattle or sheep are completely restricted, so that the main body 1 is always outside the range of motion of the hind legs, thereby protecting the milking workers sitting on the main body 1. When one hind leg is kicked, its force is applied to the other hind leg through the tube beam 4. Since the tube beam 4 is not connected to the main body 1, the kicking of cattle or sheep will not bring the main body 1 down, and the milking workers will not fall, thus ensuring good safety. Example 2

[0024] like Figures 4 to 6 As shown, based on Embodiment 1, it also includes two locking blocks 13 and two locking slots 14. The other ends of the first strap 7 and the second strap 8 are both equipped with locking blocks 13. Two locking slots 14 are provided on the side wall of the pull rod 9, with the two locking slots 14 facing the first fixed seat 5. The two locking blocks 13 are respectively locked in the two locking slots 14. It also includes two buckles 16, two hanging rods 17, two hooks 18 and two strong magnetic blocks 19. The two buckles 16 are respectively installed on one end of the first strap 7 and the second strap 8. The hanging rods 17 are installed on both buckles 16. The two hooks 18 are installed on the side wall of the pipe beam 4. The two hooks 18 are respectively located on the side of the first fixed seat 5 and the second fixed seat 6. The two hooks 18 are respectively used to hang the two hanging rods 17. The two strong magnetic blocks 19 are respectively installed on the two hooks 18. The two strong magnetic blocks 19 are used to position and attract the two buckles 16.

[0025] By setting two locking blocks 13 and two locking slots 14, it is convenient to quickly install and remove one end of the first binding strap 7 and one end of the second binding strap 8 from the pull rod 9. The two buckles 16 are respectively placed into the two hooks 18, so that the two buckles 16 are attracted and positioned by the two strong magnets 19, and the two hooks 18 are hung on the two hanging rods 17. This facilitates the quick installation and removal of one end of the first binding strap 7 and the second binding strap 8 from the tube beam 4. It also makes it convenient to quickly remove the tube beam 4 from between the two hind legs of cattle and sheep by shaking the tube beam 4 after loosening the first binding strap 7 and the second binding strap 8 after milking, thus improving work efficiency. Example 3

[0026] like Figures 1 to 3 As shown, based on Embodiment 1, it also includes a sliding hole seat 20 and a chisel 21. The sliding hole seat 20 is installed on the side wall of the pipe beam 4, and the chisel 21 is slidably inserted into the sliding hole seat 20. It also includes a first connecting ring 22, a second connecting ring 23, a first rope 24, a second rope 25, and a buckle 26. The first connecting ring 22 is installed on the pipe beam 4, the second connecting ring 23 is installed on the wheel 2, the second connecting ring 23 and the first connecting ring 22 are connected by the first rope 24, one end of the second rope 25 is connected to the first connecting ring 22, and the other end of the second rope 25 is fitted with a buckle 26.

[0027] After binding the two hind legs of the cattle and sheep with straps 7 and 8, the chisel 21 is inserted into the ground, so that the chisel 21 and the sliding hole seat 20 fix the pipe beam 4 to a certain extent, thereby improving the limiting effect on the hind legs of the cattle and sheep. The pipe beam 4 is flexibly connected to the main body 1 through connecting ring 22, rope 24 and connecting ring 23 to prevent the pipe beam 4 from being lost. The pipe beam 4 is connected to the fence or to one of the front legs of the cattle and sheep through connecting ring 22, rope 25 and buckle 26, thereby further improving the limiting effect on the hind legs of the cattle and sheep and improving the anti-kick effect.

[0028] like Figures 1 to 6As shown, this utility model discloses a hind leg restraint device for milking cattle and sheep. During operation, multiple wheels 2 first move the main body 1 to the rear of the cow or sheep. The tube beam 4 is then removed from the storage chamber 3. The two hind legs of the cow or sheep are inserted between the first fixing seat 5 and the first binding strap 7, and between the second fixing seat 6 and the second binding strap 8, respectively. Then, the pull rod 9 is pulled outwards, simultaneously tightening the first binding strap 7 and the second binding strap 8. This allows the first binding strap 7 and the first fixing seat 5 to secure one hind leg, while the second binding strap 8 and the second fixing seat 6 secure the other hind leg. The elasticity of the spring plate 12 presses one end of the limiting rod 11 against a ratchet 10, thus achieving restraint. The unidirectional limiting of lever 9 prevents the first strap 7 and the second strap 8 from loosening. Then, the tube beam 4 is connected to the fence or to one of the front legs of the cow or sheep through connecting ring 22, rope 25 and buckle 26. In this way, the two hind legs of the cow or sheep are mutually limited by the tube beam 4. Under normal circumstances, the cow or sheep only kicks with one hind leg and supports its body with the other hind leg. When the cow or sheep moves, the two hind legs will not move together. Finally, when the tube beam 4, fixed seat 5, fixed seat 2 6, strap 7 and strap 2 8 limit the two hind legs to each other, the kicking and lateral movement of the cow or sheep are completely restricted, thereby protecting the milking staff sitting on the main body 1.

[0029] The main functions achieved by this utility model are:

[0030] 1. It can limit the two hind legs to each other, and the kicking and lateral movement of cows or sheep are completely restricted, so that the main body 1 is always outside the range of motion of the hind legs, thereby protecting the milking workers sitting on the main body 1.

[0031] 2. When one hind leg kicks, the force is transferred to the other hind leg through the tube beam 4. Since the tube beam 4 is not connected to the main body 1, the main body 1 will not be knocked down when the cattle or sheep kick, which also prevents milking workers from falling and ensures good safety.

[0032] 3. Straps 7 and 8 are easy to install and remove, making it convenient to tie and loosen the two hind legs, thus improving work efficiency.

[0033] This utility model discloses a hind limb fixation device for preventing kicking during milking of cattle and sheep. Its installation, connection, or setting methods are all common mechanical methods, and any method that achieves the desired beneficial effect can be implemented. The main body 1, wheel 2, tube beam 4, fixing seat one 5, fixing seat two 6, strap one 7, strap two 8, pull rod 9, ratchet 10, limiting rod 11, spring plate 12, locking block 13, buffer sleeve 15, strong magnetic block 19, sliding hole seat 20, chisel 21, connecting ring one 22, connecting ring two 23, rope one 24, rope two 25, and buckle 26 of this utility model are commercially available.
