Description

Ox stomach gets iron ware

Technical Field

The invention relates to the technical field of prevention and treatment instruments for livestock husbandry and veterinarian, in particular to a cattle stomach iron remover.

Background

The existing iron-taking device for ox stomach is made up by fixing one end of disk or cylindrical permanent magnet and one end of cylindrical spring together, and making the pull rope pass through the interior of spring and tie with the end of magnet fixed spring, then making the other end of pull rope pass through the small hole on the top end of cross-sectional semi-eggshell-shaped shell body, and making the spring and magnet be placed into the shell body. The iron extractor for the cattle stomach sold in the market is in the form, the permanent magnet of the existing iron extractor for the cattle stomach is magnetized along the axial direction, only the top end of an iron object can be adsorbed with the permanent magnet, the iron object is still in an open magnetic circuit after being adsorbed, a closed magnetic circuit cannot be formed, and therefore the adsorption force is small. In addition, the adsorbed iron object can not be directly sucked into the cavity of the shell, but when the pull rope is tightened to enable the spring to contract, the permanent magnet and the adsorbed iron object are brought into the cavity of the shell, and the iron object is ejected out of the cavity of the shell by the spring after the pull rope is slightly loosened. Therefore, when the existing cattle stomach iron extractor is used for extracting iron, the situation that the iron-absorbing object falls off or is ejected out of the cavity of the shell due to poor absorption often causes new injury to cattle.
