The automatic feeding and calibrating device according to claim 4, wherein the spiral blanking device comprises a blanking shell, a rotating shaft rotatably arranged in the blanking shell, and a motor for driving the rotating shaft to rotate, wherein the blanking opening is arranged in the middle of the blanking shell, a rear spiral blade and a front spiral blade with opposite rotation directions are arranged on the rotating shaft, two openings are respectively arranged above the rear spiral blade and the front spiral blade, an angular plate is fixedly connected to the connecting shell, and the angular plate guides feed into the openings.
9. The automatic feeding and calibrating device according to claim 8, wherein a beating block is fixedly connected to a rotating shaft section between the rear spiral blade and the front spiral blade, the beating block can seal the feeding hole, the outer end of the beating block is provided with a groove, and a plurality of beating teeth are fixedly connected in the groove.
10. Calibration method using a feeding automatic calibration device according to any one of claims 1 to 9, characterized in that it comprises the following steps:
step one: the feeding machine walks to the calibration device and stops by the limiting mechanism;
step two: the spiral blanking device operates the feeding time T of each group of breeding cages according to the theoretical rotation speed, the weighing machine measures the measured feed quantity of the feed, the rotation speed R of the spiral blanking device is calibrated, and the calibration formula is as follows:
D＝M×N；
k=v×ρ=measured amount/(r×t);
R＝M×N/(K×T)；
wherein D is the required feed amount, M is the target feed amount of each chicken, N is the number of preset chickens, T is the feeding time of each group of breeding cages, K is the feed amount per rotation, V is the volume per rotation, and ρ is the feed density;
step three: the spiral blanking device runs the feeding time T of each group of breeding cages according to the calibrated rotating speed R, and whether the difference value between the actually measured material quantity and the required material quantity is in an error range is verified;
step four: ending the calibration when the difference value between the actually measured material quantity and the required material quantity is within the error range; and when the difference value of the actually measured material quantity and the required material quantity is out of the error range, calibrating the rotating speed R according to the calibration formula in the third step until the difference value of the actually measured material quantity and the required material quantity is in the error range.
