Abstract: A system for managing objects is provided. The system comprises a data collection gateway and a plurality of apparatus. Each of the plurality of apparatus obtains parameters relating to objects in a farm from a server through the data collection gateway. The parameters include a reference threshold weight of the objects. Each of the plurality of apparatus collects weights of the objects through sensors. Also, each of the plurality of apparatus adjusts the reference threshold weight based on the obtained parameters to generate an adjusted threshold weight. Further, each of the plurality of apparatus sorts the objects to different areas in the farm based on the adjusted threshold weight and the collected weights.

Abstract: A self-feeder for sows, which includes a hopper, a feed volume adjusting mechanism, and a discharge mechanism. The hopper includes a C-shaped housing, a front side plate, a bottom plate, and a guide plate. A gap is disposed between the bottom plate and the front side plate and used as a discharge port. The discharge mechanism includes a discharge plate, a push rod, a top cap, and a stop pin. An upper end of the push rod passes through the bottom plate and the guide plate and is welded to the discharge plate. The self-feeder has a simple structure; the feed volume can be adjusted freely, and fodder can be discharged avoiding falling on the eyes and snout of a sow; the manual discharging times is reduced; the sow can eat fresh fodder and the fodder may not get out; therefore, the fodder is not wasted and manpower is saved.

Abstract: Disclosed in the present invention is a self-feeder for sows, which includes a hopper, a feed volume adjusting mechanism, and a discharge mechanism. The feed volume adjusting mechanism is mounted in the hopper. The hopper includes a C-shaped housing, a front side plate, a bottom plate, and a guide plate. The front side plate is fixed on the front side of the C-shaped housing. The bottom plate is welded on the bottom of the C-shaped housing. A gap is disposed between the bottom plate and the front side plate and used as a discharge port. The guide plate is welded between the bottom plate and a rear wall of the C-shaped housing and is aligned with the bottom plate at the discharge port. The discharge mechanism includes a discharge plate, a push rod, a top cap, and a stop pin. The discharge plate is located above the guide plate. The top cap is located below the bottom plate. An upper end of the push rod passes through the bottom plate and the guide plate and is welded to the discharge plate.
