Double-locking-sleeve curved bar neck yoke

Abstract

The invention relates to the field of animal husbandry equipment, in particular to a double-locking-sleeve curved bar neck yoke. The double-locking-sleeve curved bar neck yoke comprises a neck yoke body and double-locking-sleeve mechanisms. The neck yoke body comprises an upper transverse rod, a lower transverse rod, a plurality of bent rods arranged between the upper transverse rod and the lowertransverse rod, vertical rods and movable swing rods, wherein the vertical rods are fixedly connected with the upper transverse rod and the lower transverse rod, each bent rod is arranged between every two vertical rods, the bottoms of the bent rods are fixedly connected with the lower transverse rod, the tops of the bent rods are fixedly connected with the vertical rods on the bent sides, and themovable swing rods are hinged to the bent portions of the bent rods; each movable swing rod comprises a lower swing rod body and an upper inclined swing rod body; each double-locking-sleeve mechanismcomprises a first locking sleeve fixedly installed at the top of the corresponding movable swing rod and a second locking sleeve hinged to the upper portion of the first locking sleeve, a plurality of locking sleeve limiting plates are fixedly installed on the upper transverse rod, the locking sleeve limiting plates are provided with through holes and through grooves above the through holes, adjusting rods penetrate in the through holes, and a plurality of stopping blocks are fixedly installed on the adjusting rods. The double-locking-sleeve curved bar neck yoke is simple in structure, complete in function, reliable in locking and easy to adjust.

Description

technical field [0001] The invention relates to the field of animal husbandry equipment, in particular to a double-lock sleeve crank neck flail. Background technique [0002] Feeding dairy cows in free stalls can improve the production efficiency of dairy cows and reduce the incidence of disease. Therefore, more and more farms have begun to abandon traditional tethered feeding and adopt free stall feeding. The main facility used in the free-stall feeding method is the cattle neck. In order to adapt to the changes in this feeding method, various equipment manufacturers have designed and manufactured different types of cattle necks to facilitate the routine physical examination, immunization, and artificial feeding of dairy cows. Management of insemination, etc. However, the existing ox headlocks can generally only realize group locks, and there are seldom ox headlocks with both functions of single lock and group lock.

AI Technical Summary

Problems solved by technology

However, the existing ox headlocks can generally only realize group locks, and there are seldom ox headlocks with both functions of single lock and group lock. The implementation process uses two holes in the crossbar of the pillory, and the swing rod is placed between the two holes and a latch is inserted to achieve locking. Making holes in the crossbar of the pillory will weaken the pillory strength, and the operation is more troublesome, the damage rate of the pillory increases, and the locking function of the existing products is not reliable enough, and the adjustment is laborious
