Description

Technical Field

[0001] The utility model belongs to the field of agricultural machinery, and specifically relates to a front-mounted direct-connected micro-tillage machine gearbox. Background Art

[0002] Powered by a small diesel or gasoline engine, micro-tillers are lightweight, compact, and simple in structure. They are widely used in dry land, paddy fields, and orchards across plains, mountainous areas, and hilly regions. Micro-tillers can be used freely in the field, making them easy to use and store. They eliminate the need for large agricultural machinery to reach mountainous fields, making them an ideal alternative to ox-drawn plowing for farmers.

[0003] Most commercially available transmissions for such tillers utilize an external belt and clutch. Due to the limited dimensions of these tillers, mud and water can easily enter the belt and clutch during field operations, especially in paddy fields, causing transmission slippage. This reduces efficiency, increases wear, and increases component damage. Current models are generally heavy, complex, and lack a sufficient number of gears, making them difficult and inflexible to use. Furthermore, most existing models feature rear-mounted cutting tools, posing a risk of injury during operation. Utility Model Content
