Due to the uneven rotation of the blade, the rotary cultivator will cause damage to the machine parts and increase the vibration of the unit, and it is not safe. The left-curved and right-curved blades should be intertwined as much as possible, so that the shafts at both ends of the knife shaft receive a balanced force. The spiral lines are arranged regularly, and the blades that are successively immersed in the soil should have the larger the axial spacing on the cutter shaft, the better, so as to avoid infarction, during the rotation of the cutter shaft for one cycle.
At the same phase angle, a knife must be immersed in the soil to ensure the working stability and the average load of the knife shaft. If more than two blades are configured, the amount of soil cutting should be equal, so as to achieve good quality of broken soil and smooth ditch bottom after ploughing. The main reason is that the material is not cut strictly according to the drawing requirements, the process tooling for production and processing is unqualified, and the management system is not perfect.
The industrial and agricultural 12-K walking tractor commonly used in Guangdong Province is equipped with a rotary tiller. There are 16 blades on the blade shaft. The left and right sides are arranged in half and half. They are used for paddy fields, dry land, etc., especially for the cultivation of vegetable fields. Even better, when the soil moisture content is less than 20%, the hand dragging should be used together with the 2BG-6A drill. The speed of the hand dragging should be 2 or 3; when the soil moisture content is greater than 30%, the speed of the hand dragging should be selected. 2 blocks.
