Description

DETAILED DESCRIPTION OF THE INVENTION (Technical field to which the invention pertains) The present invention relates to a tillage device for cultivating virgin land.

(Problem to be solved by the invention and its characteristics) When cultivating uncultivated land overgrown with bamboo trees, bushes, etc., it is common practice to cut down the bamboo grass, trees, etc., burn them, and then plow the land with a plow. , there are places where incineration is not possible, and
It is also a waste of resources to go to the trouble of incinerating organic matter that can be used as fertilizer.

From the above-mentioned viewpoint, the present invention aims to provide a cultivation device for undeveloped land that can cut and crush bamboo, shrubs, etc. including their roots, and bury them underground. Its structural features are as described in the claims.

As is clear from its characteristic configuration, the tillage device of the present invention is attached to the rear of a tractor, and as the tractor moves forward, the cutting blade on the front rotating shaft cuts and crushes the above-ground parts of bamboo, shrubs, etc. The cutting blade on the rotating shaft at the rear cuts and crushes the underground parts (roots) of bamboo trees, shrubs, etc., and also digs up the soil.

(Detailed Description of the Invention with Drawings) In the drawings showing an embodiment of the present invention, 1 is a tilling device of the present invention, in which a top plate 3 is attached to a support frame 2, and side plates 4, 4' extends downward.

Two rotating shafts 5, 6, front and rear, are installed between the side plates 4 and 4' at different heights, and the front rotating shaft 5 is located higher than the rear rotating shaft 6.

A large number of heavy cutting blades 7 are attached to each of the rotating shafts 5 and 6 via chains 8 at equal intervals in the length direction and shifted by 90° in the circumferential direction.

In the illustrated case, the cutting blade 7 has a tip that opens left and right, and cutting edges 9 and 9' are formed at both the front and rear ends.

In addition, the attachment of the chain 8 to the rotating shafts 5 and 6 is as follows.
This is done through a pair of retaining grooves 10, 10' and a pole 11, so that when the cutting blade 7 becomes worn, it can be reversed and the attachment can be changed or replaced with a new one. (See Figures 3 and 4).

The support frame 2 is removably attached to the rear of the tractor 14 via fixed arms 12, 12' and telescopic arms 13, and can be tilted up and down about an axis, a line 15.

There is a gear box 16 on the support frame 2, and the tractor 14
The rotation of the drive shaft 17 extending from the drive shaft 17 is transmitted to the left and right shafts 19 and 19' via a bevel gear mechanism 18 within the gear box 16.

The rotation of the shaft 19 is transmitted to the rotating shaft 6 by the chain 21 in the chain case 20 on one side, causing it to rotate once counterclockwise, and the rotation of the shaft 19' is transmitted to the rotating shaft 6 through the chain 21 in the chain case 20 on the other side. It is transmitted to the rotary shaft 5 by the chain 21 inside, and rotates it clockwise.

The rotation locus of the cutting blade 7 rotating at 115 is approximately in contact with the ground surface, and the rotation locus of the cutting blade 7 of the rotating shaft 6 is designed to enter the ground at an appropriate depth.

When the rotating shafts 5 and 6 are rotated at high speed, the cutting blade 7 of the rotating shaft 5 cuts and crushes the above-ground parts of bamboo, shrubs, etc.
The cutting blade 7 cuts and crushes the underground parts (roots) of bamboo grass, shrubs, etc. and digs up the soil 9, but if the cutting blade 7 hits a stone or the like, the chain 8 acts as a relief.

Reference numeral 22 denotes a height adjusting roller, which is installed between the side plates 4 and 4' in a vertically adjustable manner. Further, 23 is a fixed blade attached to the top plate 3 for shredding bamboo grass, shrubs, etc., and 24 is a rear extension of the top plate 3, which functions as a pressing plate to flatten the tilled soil.

(Effects of the Invention) The tillage device of the present invention is as described above, and when it is attached to the rear of a tractor and used in a virgin land, it can cultivate both the above-ground parts and the underground parts (roots) of bamboo grass, shrubs, etc. Bamboo,
It can be used as fertilizer without burning shrubs, etc. as in the past, and it is highly efficient and highly effective.

Claims (1)

[Claims] Side plates are installed vertically on both sides of a support frame that is detachably attached to the rear of the tractor, and two rotating shafts (front and rear) are installed at different heights between these side plates, and each of these rotating shafts is equipped with a large number of heavy cutting blades. It is attached via a short chain, and the rotating trajectory of the cutting blade on the front rotating shaft is almost in contact with the ground surface, and the rotating trajectory of the cutting blade on the rear rotating shaft goes into the ground at an appropriate depth.
