Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a rotary tillage device for pasture renewal, and more particularly to a tillage device that can perform surface treatment of pastureland after cutting and plowing at the same time.

[Conventional technology]

In recent years, rotary tillers have been increasingly used to regenerate aging pastures. In this tilling device, unlike those used to till cultivated land such as fields, the tilling device has a horizontal blade in a machete that is hardly bent from the vertical blade, and the vertical blade is extended in a nearly straight line. Using a straight-edge knife blade or disc blade, etc., the grass roots are cut while cultivating the cultivated land below. New shoots are then sprouted from the cut roots on the plowed land, improving grass vigor and increasing the yield of pasture.

[Problems to be solved by the invention]

By the way, the surface of the meadow is littered with uncut grass, compost sprinkled from above the grass, household manure, etc., so after the renewal work is carried out, these scattered materials and There was a problem in that the growth of new buds was inhibited by the cultivated soil that had piled up on the surface as a result of renewal work.

[Means and actions to solve the problem]

Therefore, in the present invention, a tilling shaft for tilling to which a conventionally known knife blade is attached is used as a first shaft, and a flail blade is attached to the rear of this first shaft parallel to the first shaft, and the first tilling shaft is is equipped with a second tillage shaft that rotates in the opposite direction, and the flail blade of the second tillage shaft crushes and levels the surface of the meadow that has been cut and tilled in the conventional manner by the first knife blade. Therefore, it is an object of the present invention to provide a rotary tillage device for pasture regeneration, which levels the surface of the regenerated pasture and provides surface treatment suitable for the growth of new shoots.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a rotary tillage device mainly used for renewing pastureland. are connected to the top link 6 and lower link 7 of the tractor 5, and power is transmitted from the tractor 5 via a transmission mechanism 8. A first tilling shaft 9 is horizontally supported at the bottom of the main body 2, and a large number of knife blades (tilting blades) 10, 10... are attached to the tilling shaft 9 in radial directions around the shaft. These blades are installed at predetermined intervals in the axial direction, and rotate from below to above in the direction of movement of the aircraft.
In other words, it is structured in an easy-to-understand format. At the rear of the first tilling shaft 9, a second tilling shaft 12 is supported in parallel with the tilling shaft 9 via a pair of left and right frames 11 that project rearward from the main body 2. One side of the frame 11 also serves as a transmission mechanism, and is configured to transmit power from the main body 2 side to the tilling shaft 12. This second tillage shaft 12
, a large number of flail blades 13 are installed radially around the shaft at predetermined intervals in the axial direction,
It has a down cut shape that rotates in the direction of the arrow. The lower end position of the rotating outer periphery of the flail blade 13 is higher than the lower end position of the rotating outer periphery of the knife blade 10, and the surface of the meadow cut and plowed by the knife blade 10 is crushed and leveled by the flail blade 13. It is laid out flat. The rotary tiller 1 having such a configuration is installed on a tractor 5 and introduced into an aging pasture that needs to be renewed, and as shown in FIG. Rotate in the direction of the arrow to perform tilling work. Then, the knife blade 10 plows the cultivated land below while cutting the roots of the grass with a cutting edge, and a part of the cultivated soil rises upward from the cutting position of the knife blade 10, making the surface of the pasture uneven. Make it. The cultivated soil mounded above, uncut grass remaining on the surface of the meadow, compost, household excrement, etc. scattered on the surface are removed by the flail blade 13 of the down cut.
This allows the grass to be crushed and leveled without difficulty while avoiding the large resistance of the grass. Therefore, the new shoots that germinate from the cut grass roots are free from obstacles during development and growth, increasing the yield of grass. In the above embodiment, the first tilling shaft 9 may be rotated in the down-cut direction, and the second tilling shaft 12 may be rotated in the up-cut direction.

【Effect of the invention】

As explained above, according to the rotary tillage device for pasture renewal of the present invention, the first
A second tilling shaft equipped with a flail blade was installed behind the tilling shaft so as to rotate in the opposite direction to the first tilling shaft, so that the knife blade of the first tilling shaft could cut,
The flail blade of the second tillage shaft removes the plowed soil (soil) that has risen upwards, as well as lumps of compost and household manure that are scattered on the surface of the pasture. It is possible to crush and level the grass while avoiding resistance, and the surface of the grass after regeneration work is leveled, allowing good growth and development of new shoots, and increasing the yield of the grass.
