The main difference between disc plow and disc harrow:
1.The objects and functions of the machines are different: the disc plough is mainly used for the tillage of the uncultivated land, and the disc harrow is used for the broken soil leveling of the cultivated land.
2. The way of connecting with the locomotive is different: the disc plow is a three-point suspension type, and the disc harrow has a large traction type and a small suspension type.
3. The structure of the machine and the force during operation are different: the disc plough is like (or is) the position where the ploughshare is installed on the three-point suspension plough, and it is used to install two to several disc plough bodies and turning plates. The structure of the assembly is equipped with a tail wheel that balances the side pressure. The unit is subjected to a large side pressure during operation; Wearing on a square shaft as a group), the force is relatively balanced during operation.
4. The structure and device of the main working parts are different: due to the high requirements for the performance of soil entry, breaking soil and turning soil, the structural strength of the disc plough body is higher, and the spherical surface of the disc plough has a large concavity (small radius of curvature), The thickness of the blade edge of the disc is 0.5-1mm, and the blade angle is generally 12 degrees. When the disc plow is working, the disc plane forms an inclination angle of 40-45 degrees with the forward direction, and an inclination angle of 15-25 degrees with the vertical plane; the disc harrow The force is relatively balanced during work, and the soil turning performance requirements are general. The requirements for the disk are good wear resistance in addition to a certain strength, the spherical concavity of the disk is relatively small (large radius of curvature), and the thickness of the disk edge It is 0.3-0.8mm, the declination angle is 0-10 degrees when it is working, and there is no inclination angle.
