Then, the field is tilled to a predetermined depth, such as the normal tillage depth, by each short tilling claw, and
Each of the long tilling claws plows the plow a predetermined depth further than the normal plowing depth, and therefore, the plowing section plowed by the rotary tiller has a normal plowing part and a partially deep plowing part. be done. In the above case, the soil clods scattered backward from the rotary tiller are
In each part, the soil is restrained at approximately the same distance by the crushing bars located at the front and rear, and the soil is crushed and separated by the impact, and relatively large clods are quickly dropped downward by the crushing bars. Also, relatively small lumps and the like are scattered backward through the gaps between the crushed earth bars and fall onto the relatively large lumps. Therefore, each plowed area after plowing is formed with a relatively coarse lower layer and a denser upper layer than the lower layer.

When the plowing shaft 6 is rotated, the tilling shaft 6 is rotated in conjunction with the interlocking medium, and the rotary tiller 10 having the tilling shaft 6 is rotated in the up-cut direction or the down-cut direction. The field is tilled to a predetermined depth h1 such as the normal tilling depth by each short tilling claw 9, and the normal tilling part is partially tilled to the normal tilling depth by each long tilling claw 8. A predetermined depth h 2 further than h 1
Only the rotary plowing body 10 is plowed.
The tilled area A that has been tilled by the tiller has a normal tillage area B and a partial deep cultivation area C. In the above case, the soil clods scattered backward from the rotary tiller 10 are separated by the first and second screens 15,
The pieces are restrained at approximately equal distances by the crushing bars 14 and 17 at 18, and crushed and separated by the impact, and the relatively large lumps are quickly dropped downward by the crushing bars 14 and 17. Also, relatively small lumps and the like are scattered backward through the gap between the crushing rods 14 and 17 and fall onto the relatively large lumps, and the surface thereof is leveled by the leveling plate 26. Therefore, each plowed area after plowing is formed into a two-layer structure, with the lower layer being relatively coarse and the upper layer being denser than the lower layer, which is ideal for crop growth with excellent air permeability and water permeability. Formed in the cultivated layer in a favorable condition.

According to the present invention, in the rear part of the rotary tiller,
A plurality of soil crushing rods facing the long tilling claws of this rotary tilling body and a plurality of soil crushing bars facing the short tilling claws of this rotary tilling body were provided with screens arranged front and back according to their respective rotation trajectories. ,
With a simple configuration, it is possible to cultivate a normal depth tillage area and a deeper tillage area side by side within a predetermined width in one process, and to cultivate these shallow and deep tillage areas with a dense upper layer and a coarse lower layer. It is possible to cultivate fields in a two-layered structure, thereby making it possible to easily create a field that is favorable for crop growth.

The screen and the rotation locus of the short tilling claws can be reliably held opposite each other with the same appropriate distance between them, and the screen can prevent the rotation of the long tilling claws, or prevent the rotation of the long tilling claws The distance between the rotary tiller and the tiller does not become large, and therefore a two-layer structure can be reliably created by the tilled soil scattered backward from the rotary tiller. Furthermore, this screen has a simple structure and is easy to manufacture and install.
