Leg fixing device for milking cows

Abstract

The invention discloses a leg fixing device for milking cows. The leg fixing device for milking the cows comprises a main board and fixing mechanisms, wherein two base boards are symmetrically fixed on the main board, three mounting boards are arranged on each base board at intervals, and a rotary shaft is movably inserted into each mounting board; one fixing mechanism is arranged between every two mounting boards, each fixing mechanism includes a fixing rod and a mobile rod, and each fixing rod is fixed on the corresponding rotary shaft; each mobile rod is movably connected to the corresponding rotary shaft. When the fixing device is in use, it is no longer necessary for the fixing device to approach a cow leg, so that a worker can be prevented from being kicked and wounded during the installation of the device, and the operation is simple; since the cow leg can be clamped and fixed by operating the rotary shafts directly, the defect of waste of time in tying and transferring a rope is overcome when the rope is in use, and no thread structures are needed any more, so that it is avoided that the device cannot be used any more because of a flattened thread; the leg fixing device formilking the cows is worth promoting.

Description

technical field [0001] The invention relates to the technical field of animal husbandry tools, in particular to a leg fixing device for milking cows. Background technique [0002] When livestock farms extract milk from cows, they first need to fix the legs of the cows to prevent the cows from kicking and injuring the staff during the milking process. At present, the fixation method adopted by most breeding farms is the way of binding the legs with ropes. , not only the operation is complicated, but also seriously affects the work efficiency, which is very inconvenient. [0003] In the prior art, in order to solve the above problems, a special fixed rope for milking cows with the application number "201320843981.7" can be fixed by simply hanging the clip on the hook ring when in use; after use, directly remove the clip from the hook ring It can be unfixed by taking it out, but the rope is prone to break after a long time of use, and it is prone to vicious winding when the ro...

[0002] When livestock farms extract milk from cows, they first need to fix the legs of the cows to prevent the cows from kicking and injuring the staff during the milking process. At present, the fixation method adopted by most breeding farms is the way of binding the legs with ropes. , not only the operation is complicated, but also seriously affects the work efficiency, which is very inconvenient

[0003] In the prior art, in order to solve the above problems, a special fixed rope for milking cows with the application number "201320843981.7" can be fixed by simply hanging the clip on the hook ring when in use; after use, directly remove the clip from the hook ring It can be unfixed by taking it out, but the rope is prone to break after a long time of use, and it is prone to vicious winding when the rope is stored, which is very inconvenient to use;

[0004] The application number is "201710534708.9", a kind of anti-kick rod for cows. When in use, the crank handle is used to drive the transmission gear to rotate. The rotation of the transmission gear drives the two-way threaded bushing on the gear to rotate. The guide seat moves relatively linearly, and the U-shaped hook moves relatively linearly to close and fix the cow's legs. However, the anti-kick stick needs to be operated close to the cow's leg when in use, and it is easy to be kicked by the cow's leg during use, and the two-way threaded bushing Long-term use can easily cause thread grinding, etc., resulting in the inability of the U-shaped hook to move closer
