[0002] When weeding or loosening the soil, a V-shaped tillage blade connected to a micro-tillage machine is often used to assist in weeding or loosening the soil. However, the position of the tillage blade is usually fixed and there is only one tillage blade, so the range of single weeding or loosening the soil is small and the tillage efficiency is low. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, one of the purposes of the present invention is to provide a double-row tiller that can increase the range of single weeding or soil loosening and improve farming efficiency.

[0004] The technical solution adopted by the utility model is as follows: a double-row tilling device is applied to a four-wheel ride-on micro-tillage machine, comprising symmetrically arranged and relatively position-adjustable tilling components for weeding or loosening soil.

The two groups of weeding and tilling components can be adjusted to a relative position, that is, they can move toward each other and be fixed in position, or move away from each other and be fixed in position. When the weeds are relatively dense, the two groups of weeding and tilling components can be adjusted to a relative position, that is, close to each other, and the gap between the two groups of weeding and tilling components is small, so the amount of weeding in a single time is large, and the weeding efficiency is improved. When the weeds are relatively sparse, the two groups of weeding and tilling components can be adjusted to a back-to-back position, that is, far away from each other, so that weeds can be removed wherever the weeding and tilling components pass as much as possible, thereby improving weeding efficiency.
