Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge making device, and relates to a ridge for continuously growing crops.

[0002]

2. Description of the Related Art Conventionally, as this type of ridge-raising device, for example, a rotary tiller for cultivating soil in a machine frame is rotatably provided, and the rotary tiller is located at the rear portion of the rotary tiller and is attached to the machine frame. A configuration is known in which a ridge molding for ridge-forming cultivated soil is provided. Then, the soil in the field is successively cultivated by the rotary cultivator, and the cultivated soil is sequentially ridged and formed into ridges of a predetermined height by the ridge molding.

[0003]

The above-mentioned structure is preferable for improving work efficiency in that a ridge having a predetermined height is continuously ridged and formed by a series of operations by the rotary tiller and the ridge forming body. However, at this time, the ridge molding is forcibly pulled toward the cultivated soil to form a ridge with a predetermined height while pushing the cultivated soil forward, so that this ridge is entirely formed. When it is molded in a state of being strongly compacted, the roots and air permeability of the crop are easily impaired because it is strongly compacted to the inside of this ridge, which is unfavorable for the growth of the crop, and the ridge is relatively small. When molded in a state of being gently compacted, there are problems that the ridges are likely to collapse, water is diffused and fertilizer is easily washed away, and rainwater is easily permeated.

The present invention has been made in view of the above circumstances, and the surface of the ridge is compacted in the ridge molding and the ridge shaping body, and the inside of the ridge is relatively gently tightened. It can be molded in the solidified state, which is why
The ridges are difficult to collapse, water is not released and fertilizer is not easily washed away, rainwater is not penetrated so much, and the rootability of the crop is not impaired. Therefore, the ridges that are preferable for the growth of the crop are continuously formed into ridges. It is an object of the present invention to provide a furrowing device that can be used.

[0005]

The ridge forming device of the present invention comprises:
Machine frame, rotary cultivator rotatably provided on this machine frame for cultivating soil, and cultivated soil cultivated by the rotary cultivator located at the rear of this rotary cultivator And a ridge-shaped body for ridge-forming, and is formed in the shape of a drum for compacting the surface portion of the ridge formed by the ridge-shaped body and rotatably provided on the machine frame located at the rear part of the ridge-shaped body. And a ridge shaping body having a shaping surface.

[0006]

In the ridge-raising device of the present invention, when the rotary tillage body and the ridge shaping body are rotated and driven, the soil is sequentially cultivated at the rotary tillage body, and the cultivated soil is transformed into the ridge formation body. While being pushed forward toward the front, the ridges are successively formed into ridges having a predetermined height, and the surface portion of the ridges is compacted by the drum-shaped shaping surface of the ridge shaping body.
That is, since the ridge shaping body is driven while being rotationally driven, the drum-shaped shaping surface of the ridge shaping body is sequentially slip-rotated while being fitted from above onto the surface portion of the ridge formed by the ridge shaping body. However, the surface portion of the ridge is compacted and shaped by this shaping surface as it proceeds. Therefore, the surface portion of the ridge is shaped in a compacted state, and the inside of the ridge is shaped in a relatively gently compacted state.

Thus, the soil is successively cultivated by the large number of tillers 8 of the rotary tiller 5, and the tilled soil is pushed forward by each of the ridge moldings 23 to a predetermined height. The ridge A having a shape is sequentially ridged and formed. That is, when each ridge molded body 23 is pulled and advanced, the pair of soil guide plates 26 guide the cultivated soil toward the front while being gathered by being guided between the pair of soil guide plates 26. Together with this tillage, each pair of ridge forming plates
27 and a curved plate 28 at the upper end of the ridge forming plate 27 are sequentially ridged and formed into ridges A having a predetermined height.

Further, the ridge shaping bodies 52 are rotatably driven along the ridges A formed by the ridge shaping bodies 23 while advancing, thereby shaping the ridge shaping bodies 52 in a drum shape. Face 53
The surface portion B of each ridge A is sequentially compacted and shaped into a drum shape. That is, since each ridge shaping body 52 is driven while being rotationally driven at a higher speed than the pulling speed of this machine, the hourglass-shaped shaping surface 53 of each ridge shaping body 52 is formed by the ridge shaping body 23, respectively. Since the ridges A are fitted to the surface portion B of the ridge A from the upper side while being sequentially slip-rotated, the left and right large-diameter portions 54 of the shaping surface 53 have hem portions of the surface portion B of the ridge A. a is sequentially compacted and shaped, and at the small diameter portion 55 of the shaping surface 53, the upper surface portion b of the surface portion B of each ridge A is sequentially compacted and shaped. Therefore, the surface portion B of each ridge A is shaped in a compacted state, and the inside of each ridge A is shaped in a relatively gently compacted state.

In the above embodiment, the case where the two ridges A are ridged and shaped by using the left and right ridge moldings 23 and the left and right ridge shaping bodies 52 arranged at the rear portion of the ridge molding 23 has been described.
Not limited to this, three or more ridges A are formed by using a plurality of ridge moldings 23 and ridge shaping bodies 52 disposed on the left and right according to the width of the rotary tillage 5 and the width of each ridge A to be ridge-shaped. You may make it ridge-shaped.

[0028]

According to the present invention, since the ridge molding and the ridge shaping body are sequentially arranged in the rear part of the rotary tillage body, the cultivated soil cultivated by the rotary cultivator body is predetermined by the ridge molding. It can be ridged and formed into high ridges,
The surface portion of this ridge can be shaped into a reliably compacted state by the hourglass-shaped shaping surface of the ridge molding that is driven to rotate,
At this time, the ridge molding is rotationally driven along the surface of the ridge so that the surface of the ridge is shaped into a compacted state, while the inside of the ridge is shaped into a relatively gently solidified state. It is possible to prevent the soil from adhering to the ridge molding,
The surface of the ridge can be neatly and neatly shaped. For this reason, the ridges are hard to collapse, the water divergence and the fertilizer are hard to wash away, and the rainwater does not penetrate so much that the rooting of the crop is not hindered by the relatively gentle hardening of the inside of the ridges. The ridges preferable for the growth of crops can be continuously ridged and formed.
