Shandong-a farmer's homemade milking machine was patented
In May 2006, Dong He, a young farmer from Nanwangzhuang Village, Guli Town, Xintai City, Shandong Province, used the vacuum negative pressure principle to make a milking machine, which was welcomed by farmers. Manual milking of farmed dairy cows not only has high labor intensity, but also affects the quality of fresh milk, and it is also easy to crush the teat. At present, this machine has won 3 national patents and has been listed as a science and technology SME innovation fund support project by the Ministry of Science and Technology. The products are sold to more than 10 provinces and cities in Jilin and Inner Mongolia, with an annual income of more than 2 million yuan. The picture shows Dong and Silver in the assembly of the milking machine.
