As is known to all, the common drawback of the current double-tillage and less-tillage machines is that the tillage, combined moisture and broken tillage is fixed when the tillage and tillage machine is in operation. When the surface of the cultivated land is uneven, stubble, Sowing deep reach the requirements. According to the above situation, the author has developed a new type of machine to change the welded fixed beam, which was originally connected to the rack assembly and the rear integrated device (broken soil, stubble, combined moisture and cracked) into a four-bar copying device with joint Through four
