Abstract: To perform operations such as shoe repair and artificial fertilization on cows, it is necessary to use a binding frame to lift the cows and bind them to the hooves. At present, there is relatively little public research on the cow positioning frame at home and abroad, and ordinary cow binding methods can easily damage their joints. Therefore, an electric lifting cow binding frame has been designed. The binding frame was composed of a complete frame, neck clamp, binding device, electric lifting mechanism, and anti kick device. The neck clamp was made of hotdip galvanized steel pipe with a diameter of 35 mm, and its size was designed based on the height and width of the neck of most adult cows. The lanyard in the binding device was used for binding cattle hooves, and the manual rocking wheel was used to prevent the lanyard from falling off the wheel. The force analysis of the binding device was carried out, and the diameters of the two rotating discs of the manual rocking wheel were determined to be 100 mm and 200 mm, respectively. By calculating the lifting power of the lifting mechanism, the motor power was determined to be 1.5 kW, the speed was 1 400 r/min, the reduction ratio of the reducer was 70, and the diameter of nylon rope was 25 mm. The test results of the prototype showed that the electric lifting guarantee frame for dairy cows could lift 936 kg cows and the lifting height was 25 cm, which could effectively protect the operators.
