Description

A neck clamp

Technical Field

The utility model relates to the technical field of animal husbandry equipment, in particular to a neck clamp.

Background Art

The neck clamp is used when feeding cows in a cattle farm, with one cow per pen, to avoid cows snatching food during feeding. The Chinese utility model patent with announcement number CN204907473U discloses a cow neck clamp, which realizes automatic locking and manual release of cows, has a simple structure, is easy to operate, and can meet the requirements of fixed-point and timed feeding, blood sampling, and drug injection. However, when the cow is small, the cow's head enters between the movable barrier and the main railing to eat. Because the cow's head is small, the cow does not need to squeeze the movable barrier to a vertical state to eat, but at this time the movable barrier is still in a slightly tilted state, and the limit mechanism cannot limit the movable barrier. The small cow can still stick its head out, affecting the feeding of other cows.

Utility Model Content

The utility model aims to provide a neck clamp, aiming to solve the technical problem that the limiting mechanism in the prior art cannot limit the head of the cattle on the neck clamp when the cattle is relatively small.

In order to solve the above technical problems, the technical solution of the utility model is:

A neck clamp comprises a fence frame, on which a limit rail and an upper cross bar are provided, a movable stop bar is hinged on the fence frame, a limit sleeve is provided at the upper end of the movable stop bar, and the limit sleeve is sleeved on the upper cross bar. Two limiters are also hinged on the fence frame, which respectively limit the two sides of the limit sleeve when the movable stop bar is swung to a vertical state. The lower end of the limit rail is suspended, and the lower end of the limit rail is hinged with a movable limit rod. A push block is slidably installed on the fence frame, and a first elastic mechanism is installed to drive the push block to push the movable limit rod to swing toward the movable stop rod.

With the above structure, when a smaller cow puts its head between the limit rail and the movable stopper to eat, the movable limit rod is in an inclined state under the action of the first elastic mechanism. Due to its lower position and the action of the first elastic mechanism, the movable limit rod is less likely to be moved by the cow's head than the movable stopper. When the cow eats, it presses down the inserted cow's head, and the movable stopper swings outward to a vertical state. The stopper limits the movable stopper, and the cow cannot extend its head. When a normal-sized cow eats, it pushes the movable stopper and the movable limit rod outward, and the stopper limits the movable stopper, and the cow cannot extend its head. The utility model provides a movable limit rod to prevent smaller cows from eating without squeezing the movable stopper to a vertical state, and the cow can still extend its head, affecting the feeding of other cows.

Preferably, the push block is spherical in shape, which can reduce the friction between the push block and the limit movable rod, thus avoiding the wear of the push block.

Preferably, the first elastic mechanism includes a fixed seat mounted on the fence, a push rod slidably mounted in the fixed seat, and a compression spring driving the push rod to slide outward, and the push block is mounted on the outer end of the push rod. The compression spring drives the push rod to extend, thereby driving the push block to move outward, so as to limit the movable limit rod in a state inclined toward the movable blocking rod.

Preferably, a limit plate is provided at the inner end of the push rod, a limit protrusion matching the limit plate is provided at the outer end of the fixing seat, and a compression spring is arranged between the bottom of the fixing seat and the limit plate. The limit plate and the limit protrusion cooperate to limit the outward movement of the push rod to prevent the push rod from falling out of the fixing seat.

Preferably, the bottom of the fence is hinged with a limit block, and a second elastic mechanism for driving the limit block in a vertical state is also installed on the fence. A limit cavity is provided at the bottom end of the movable limit rod, and the limit block can be limited in the limit cavity when the movable limit rod is in a vertical state. When a normal-sized cow eats, the movable stop rod and the movable limit rod are pushed outward, and the limiter limits the movable stop rod. When the movable limit rod swings down, the limit block swings down under force, and after the movable limit rod passes over the limit block, it is reset to a vertical state under the action of the second elastic mechanism, and the movable limit rod is limited in a vertical state, so that the normal-sized cow does not need to squeeze the movable limit rod all the time when eating. The setting of the limit cavity allows the limit block to be limited in the limit cavity, so that the cow does not squeeze the limit block when eating, causing the limit block to swing. After feeding, the movable limit rod is manually reset.

Preferably, the top surface and the outer side surface of the limit block are connected by an arc surface. The setting of the arc surface can reduce the wear of the limit block.

Preferably, the push block is made of nylon, which can improve the wear resistance of the push block and increase the service life of the push block.

After adopting the above technical solution, the beneficial effects of the utility model are:

The utility model provides a movable limit rod to prevent a small cow from eating without squeezing the movable stop rod to a vertical state, and the cow can still stick its head out, affecting the feeding of other cows. The spherical push block can reduce the friction between the push block and the limit movable rod, thereby avoiding wear of the push block.
