The dairy scraper is also called a smart scraper or a smart scraper. During use, the chain needs to drive the scraper to clean up cow dung, so the chain will produce friction with the ground. Therefore, the chain for the manure scratch machine uses the 80 -level manganese steel chain with high hardness and good wear resistance. The carrying capacity is also better. The chain needs to be installed on the site. This requires the connection ring of the chain. The connection ring can not only connect the chain, but the appearance is similar to the chain ring, and the chain is not affecting the chain. When using the diameter of the chain, you need to select different specifications of the connection ring.
