Description

Technical Field

[0001] The present application belongs to the technical field of animal husbandry equipment, and more specifically, to a positioning fence with free entry and exit. Background Art

[0002] With the vigorous development of my country's pig farming industry, the degree of intensiveness and scale is becoming increasingly larger. In order to reduce the land occupied by pig farming, most pig farms adopt positioning stall breeding.

[0003] Existing positioning pens go against the biological characteristics of pigs. Since sows live in a fixed, small space for a long time, they lack exercise and are hampered from performing basic behaviors such as turning, walking, foraging, scratching, arching, biting, and socializing. Pigs in positioning pens are prone to abnormal behaviors such as empty chewing, biting the pens, and excessive drinking, and may even cause physical damage and reproductive diseases, leading to prolonged delivery time, dystocia, indigestion, and decreased production performance.

[0004] The disadvantages of existing positioning fences are as follows: the rear door of the positioning fence is mostly opened and closed by rotating left and right, which requires the width of the rear aisle to ensure that there is enough space for the rear door to rotate left and right; and the increase in the width of the aisle will inevitably require the increase in the width of the pig house, which will in turn have higher requirements on the design and civil construction of the pig house, and the investment will also increase accordingly; the front door and rear door of the positioning fence are designed independently and need to be controlled separately, which is inconvenient for the staff to operate. Summary of the invention

[0005] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a positioning fence that can be freely entered and exited. The technical solution adopted in this application is:

The operating shaft is rotatably arranged above the fence body, and the lock hook is arranged directly above the front fence door; the operating shaft is arranged along the front and rear directions.

[0010] Preferably, a locking handle is provided at the rear end of the operating shaft.

[0011] Preferably, the gate is provided with a door lock, the door lock is provided with a limit plate, a limit beam and an operating rod, the limit plate is arranged at the rear end of the limit beam, and the operating rod is linked to the limit plate; the limit beam is fixedly arranged at the upper end of the side rail, and the operating rod is movably arranged on the gate.
