PURPOSE: A device for sorting finishing pigs for market based on body weight is provided to standardize the quality of pork and to improve the grade of the pork. CONSTITUTION: A device for selecting finishing pigs for market based on body weight comprises an entrance door(11), an intermediate door(12), a weight measurement unit(13), a controller(15), door opening and closing units(16), sensors, and a chassis(17). The entrance door is formed on the front surface of the device so that pigs can be entered one by one. The intermediate door is opened with the entrance door and drives the pigs passing through the entrance door inward. The weight measurement unit measures the weight of the pigs and sorts the pigs based on a pre-set standard. The controller controls the opening and closing of the entrance and intermediate doors. The door opening and closing units are installed in the entrance and intermediate doors. The sensors sense the access of the pigs and the opening and closing of the entrance and intermediate doors. |
