First of all, the standard requirements of external dimensions have a great effect and influence on the rotary tiller blades, including various technical data such as the material, length, width, thickness, turning radius, hardness, and bending angle of the rotary tiller blades etc. The rotary cultivator blades with the right size and reasonable hardness can cut into the ground at a suitable angle when it is plowing, that is, when rubbing against the ground, to maintain the high efficiency and wear resistance of the blade, and achieve a high efficiency and high wear resistance. If the size of the rotary cultivator blade itself is unqualified, it will cause the blade to enter the soil angle is unreasonable, seriously reduce the efficiency of farming, and also greatly increase the oil usage amount of the rotary tiller; if the rotary tiller blades hardness is too high, which will cause the blade to break easily. If the rotary tiller blades hardness is too low, the blade will be easily deformed. Therefore, quality is the fundamental element of the rotary tiller blades.
Next, before the rotary tillage operation, the arrangement and installation of the rotary tiller blades is very important. Improper installation will seriously affect the quality of work, and due to the unbalanced blade rotation, it will cause damage to the mechanical parts and increase the vibration of the unit, which is unsafe. Left-bend and right-bend blades should be staggered as much as possible to balance the forces on the bearings at both ends of the cutter shaft. Generally, the blades are arranged in a spiral line. For the blades that are successively inserted into the soil, the larger the axial distance on the cutter shaft, the better, so as to avoid clogging. During the rotation of the knife shaft, one knife must be inserted into the soil at the same phase angle to ensure working stability and uniform load on the knife shaft. With more than two blades, the amount of soil should be equal to ensure that the soil quality is good and the bottom of the ditch is flat after ploughing.
Finally, the model compatibility of the rotary tiller blades and the rotary tiller and the working speed of the rotary tiller are also very important. Among them, the knife seat type and the knife disc type rotary tiller are mostly used to loosen soil and flat fields before planting.
