Because the compacting mechanism 6 adopts the compacting roller that has trapezoidal recess 61, trapezoidal recess 61 cooperatees with the trapezoidal clamp plate structure of soil preparation mechanism, and is effectual to the compacting after the seeding, not only does benefit to the soil moisture conservation, also does benefit to later stage irrigation and maintenance simultaneously.
Each chain transmission of the invention consists of two chain wheels and a transmission chain, and the chain transmission is driven to rotate by a land wheel; the chain drives can also be connected to hydraulic motors of the tractor, and the tractor drives the mechanisms to work.
It should be understood that the detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can be modified or substituted equally to achieve the same technical effects; as long as the use requirements are met, the method is within the protection scope of the invention.
