the liquid inlet pipe (15) is connected with the breast milk cylinder, at the moment, the breast milk enters the storage cylinder (1) through the liquid inlet pipe (15), and the added breast milk amount is calculated by the flowmeter (16), at the moment, the first motor (4) works to drive the rotating shaft (5) to rotate, then the outer shaft (6) and the inner shaft (7) are driven to rotate, the opening compound feed in the storage box (3) enters between the adjacent outer blade (8) and inner blade (9) and automatically falls into the weighing box (14) along with the rotation of the rotating shaft (5), the opening of the weighing box (14) which falls into the weighing box is matched with the feed mass through the weighing sensor, at the moment, the threaded rod (11) is driven to rotate through the rotating handle, further driving the inner shaft (7) and the baffle seat (10) which are connected by screw thread to move, realizing the extension and contraction of the inner shaft (7) and the inner blade (9) in the outer shaft (6) and the outer blade (8), adjusting the space for conveying the open compound feed, then the second motor (12) drives the rotating rod (13) to rotate, at the moment, after the weighing box (14) is turned over, the mass of the open compound feed automatically falls into the storage cylinder (1), the third motor (19) drives the stirring shaft (20) and the stirring blade (21) to rotate to mix the open-ended compound feed with breast milk, the mixture of the open compound feed and the breast milk in the storage cylinder (1) is heated by a heating plate (18) for heat preservation, and the discharging is completed by a discharging valve (22);
the open-mouth compound feed comprises the following raw materials in parts by weight: 300-400 parts of corn, 50-70 parts of soybean, 60-70 parts of vinasse, 30-40 parts of low gluten flour, 10-20 parts of soybean oil, 50-100 parts of season-dried vegetables and 5-10 parts of probiotics;
the suckling pig compound feed comprises the following raw materials in parts by weight: 300-400 parts of puffed corn, 50-70 parts of puffed soybean, 40-100 parts of fermented soybean meal, 100-120 parts of vinasse, 0.2-0.4 part of complex enzyme, 50-80 parts of season-dried vegetables and 20-30 parts of hawthorn.
