[0001]

BACKGROUND OF THE INVENTION The present invention is directed to an inclined claw barrel provided on both left and right sides of a center case and a horizontal claw barrel provided on an outer portion of the claw barrel in opposite directions. Rotary tilling device that rotates and drives to tilt, and the tilling claw and the horizontal claw shaft cylinder cancel each other by the counter rotation of the tilling claw to suppress the dash phenomenon of the body and to cultivate. It is.

[0002]

2. Description of the Related Art In the axial direction of a tilling shaft projecting left and right from a center case, inclined claw shaft cylinders are rotatably mounted on both left and right sides of the center case, respectively. Horizontal claw shaft cylinders are respectively disposed outside the inclined claw shaft cylinders, and each horizontal claw shaft cylinder is driven by a forward rotation drive mechanism, and each inclined claw shaft cylinder is rotationally driven by a reverse rotation drive mechanism. The inclined claw shaft which rotates in the opposite direction to the cultivation claw of the tube The horizontal claw shaft cultivation claw and the inclined claw shaft cylinder while cultivating the soil below the center case by the cultivation claw of the claw 2. Description of the Related Art There is known a rotary tillage device that suppresses a dash phenomenon of an airframe by counteracting rotation of a tillage claw by reversing rotation (for example, see Japanese Patent Publication No. 46-39041).

[0003]

In the rotary tilling apparatus as described above, the cultivation claw of the horizontal claw shaft tube rotates around the horizontal axis, and the inclined claw shaft tube is cultivated by the tillage. The claw rotates around an axis that is inclined at a fixed angle with respect to the horizontal axis, and the tilling claw of the inclined claw shaft tube and the cultivating claw at the inner end of the horizontal claw shaft tube adjacent thereto are above the inclined claw shaft tube. In the lower part of the inclined claw shaft cylinder, it rotates in a state where it is largely separated from each other, so that there is a residual cultivated part between the two tilling claws that is not plowed by any of them. There is a problem that the tilling finish is irregular because the tilling is not eliminated. The present invention has been made in view of such a problem, and an object of the present invention is to cancel out an airframe by a counteraction of a horizontal claw shaft tube and a slanted claw shaft tube by counter-rotating rotation of the claw shaft. A rotary tillage device that plows while suppressing the dash phenomenon of the above, but does not allow residual tillage to occur between the tilling claw of the inclined claw shaft cylinder and the cultivation claw at the inner end of the horizontal claw shaft cylinder adjacent to it. It is to make.

[0004]

In order to achieve the above object, a rotary tillage device according to the present invention comprises a center cage.
The inclined claw shaft cylinders arranged on both left and right sides of the shaft and the horizontal claw shaft cylinders arranged outside the inclined claw shaft cylinders are driven to rotate in opposite directions, and the inclined claw shaft cylinders In a rotary tilling device in which a horizontal claw shaft cylinder is cultivated while suppressing a dash phenomenon of an airframe by counteracting rotation of a tilling claw by counter rotation, an inclined claw shaft cylinder and a horizontal claw adjacent thereto are provided. The shaft cylinder is formed such that the rotating diameter of one cultivating claw is larger than that of the other, and the horizontal blade portion of the cultivating claw having a large rotating diameter is above the inclined claw shaft cylinder. The other tilling claw is configured to be wrapped outside the horizontal blade portion. Then, the rotation diameter of the inclined claw shaft cylinder is set smaller than the rotation diameter of the horizontal claw shaft claw adjacent thereto, and the inclined claw shaft cylinder has a horizontal blade portion of the tillage claw. The horizontal claw shaft tube is positioned so that the horizontal blade of the tilling claw wraps over the inclined claw shaft tube, and the horizontal claw shaft tube is adjacent to the tilling claw. The amount of eccentricity of the lateral blade portion of the tilling nail can be formed larger than that of other tilling nails. In addition, the rotation diameter of the inclined claw shaft cylinder is set to be smaller than the rotation diameter of the horizontal claw shaft claw adjacent thereto, and the inclined claw shaft cylinder has a horizontal blade portion of the tillage claw. The horizontal claw shaft tube is arranged so that the horizontal blade portion of the cultivating claw wraps over the inclined claw shaft tube outside, and the horizontal claw shaft tube is disposed in the crocodile shaft. The rotating diameter of the other than the tilling nail adjacent to the cultivating claw of the tube can be configured to match the rotating diameter of the inclined claw shaft cylinder of the cultivating claw. The rotation diameter of the horizontal claw shaft cylinder adjacent to it is formed smaller than the rotation diameter of the tilling claw, and the horizontal claw shaft cylinder is located outside the horizontal blade of the tilling claw and above the inclined claw shaft cylinder. The horizontal blade portion of the cultivating claw may be configured to be wrapped, and the rotation diameter of the cultivating claw group of the horizontal claw shaft cylinder may be matched.

[0005]

In the rotary tilling apparatus constructed as described above, the inclined claw shaft cylinders located on the left and right sides of the center case and the horizontal claw shafts located outside the inclined claw shaft cylinders are provided. The cylinders are driven to rotate in opposite directions to each other, and the inclined claw shaft cylinder and the horizontal claw shaft cylinder are counteracted by the counter rotation of the crawling claw, and the dashing of the aircraft is suppressed while the dash phenomenon is suppressed. However, at this time, the inclined claw shaft tube and the horizontal claw shaft tube adjacent to it are so set that one rotation diameter is larger than that of the other. Since the horizontal blade portion of the cultivating claw having the larger rotation diameter is formed so as to wrap outside the horizontal blade portion of the other cultivating claw above the inclined claw shaft cylinder, the inclined claw shaft cylinder is The cultivation claw and the cultivation claw at the inner end of the horizontal claw shaft cylinder adjacent to it are large below the inclined claw shaft cylinder. Never be large Zanko between gone both tilling claws be.
