6. Adjustment of exciting force: A. remove the protective cover; B. loosen the two inner eccentric blocks; C. adjust the two outer eccentric blocks in the same phase and at the same angle; D. tighten the adjusting bolts and install the protective cover; e. the temperature rise of the vibration motor bearing shall not be greater than 80oC (resistance method)
7. During the operation of the ore drawing machine, attention should be paid to whether the movement of the machine body is stable. If abnormal operation or abnormal sound is found, the machine should be stopped immediately for inspection. 8. The bearing of vibration motor shall be lubricated with 3 # lithium grease once a week. The bearing shall be inspected and cleaned once a year to check the wear degree of the bearing. If necessary, it shall be replaced and repaired in time

Chinese ancient currency is relatively rare. Like shells and stones of ancient times, the oldest are some of the food they beat. Then there are coins of various shapes made of copper. Next is our world fixed currency gold and silver. There is also the paper money that we made in Song Dynasty
China is a country with 5000 years of cultural history. So our country has the most exotic currencies. In the Yellow River Valley in ancient times, we didn't have money, we all hunted together, and then we went back to our houses to share our prey. So money at that time was food, that is, the food of other animals was exchanged for the food of other animals. With the increase of the number of people living in groups, our currency has been replaced with shells and more beautiful stones, which is a manifestation of the progress of life. When people know how to dress up, they will wear shells in strings around their necks. For example, the first Chinese dragon unearthed in Puyang City, Henan Province, is a dragon shaped pattern with shells{ RRRRR}with the development of time, the initial country was formed, and the country unified its currency. Our currency became a copper currency. There are many shapes of this kind of currency, such as round, concentric circle, square, knife and so on. After that, gold will appear in our vision. Yuanbao appeared in our country, which is the unique currency of our country. In the Song Dynasty, our country was highly developed, and the circulation of money was very large. In some places, there will be banknotes, which are made by many businesses together. This is a pioneering work of our country, and it has also influenced the world. Our country is still using paper money as our common currency. The history of currency is a development history of our country. The development of currency represents the development degree of our country. All kinds of exotic currencies represent the brilliant development history of our country
