转刀齿轮箱

The working part of the rotary tiller is a straight or curved blade, which is fixed on the cutter shaft by a plurality of blades. In operation, the cutter shaft is driven to rotate by the power output shaft of the tractor. Therefore, the working component is called a drive rotation. Working parts, when the rotary tiller is working, the blades rotate at a certain speed and advance in random groups to form a milling process for the soil - cutting, crushing and throwing backwards.

旋耕机是配备拖拉机完成犁耕和锄耕作业的耕作机械。因其破土能力强，耕后表面平整，已被广泛使用。同时可将埋在地表以下的根部剪断，方便播种机的操作，为后期播种提供良好的苗床。正确使用和调整旋耕机对于保持其良好的技术状况和确保耕作质量非常重要。

旋耕机产品分类及发展趋势

一、横轴型：破土能力强，多用于灌丛地、沼泽地、草荒地的栽培。工作部分包括旋转刀辊和按多头螺旋均匀排列的多个切割刀片，由拖拉机动力输出轴通过传动装置驱动，常用转速为190～280转/分。刀辊的转动方向一般与牵引轮转动的方向相同。切割刀片从前到后切割土壤层，并将土块向后并向上抛到套管和托架上以进一步破碎。当刀辊切土抛土时，土对刀辊的反作用力有助于推动机组前进。因此，卧式旋耕机在作业过程中需要很少的牵引力，有时可以通过刀辊推动机组前进。

The cutting blade can be divided into a chisel knife, a machete, a right angle knife and a curved knife. The front end of the chisel-shaped knife is narrower, has better ability to enter the earth, and has low energy consumption, but is easy to entangle the grass, and is mostly used in vegetable gardens and courtyards with few weeds. The curved edge of the machete has a sliding effect, which is easy to cut the grass roots without entanglement, and is suitable for paddy field farming. Right-angled knives - with vertical and horizontal cutting edges, the blade is wide, rigid and easy to manufacture, but the soil is poor. The curved knife has high strength, good rigidity and good sliding action, and is usually used on a heavy-duty rotary tiller. When it is used with tractors below 15 kW, it is generally connected directly without universal joint transmission; when it is matched with tractors of 15 kW or more, it adopts three-point suspension type and universal joint transmission; heavy-duty rotary cultivators generally adopt traction type.
