部の前後長が長くなり易い。Problems to be Solved by the Prior Art and the Invention When a rotary-type tilling device is provided with core soil claws on the rear side for deeply cultivating the bottom of the tiller, the core soil claws are connected to the tiller claws of the front tillage device. Since it is generally provided at a position rearward and removed from the rotational diameter (Utility Model Application No. 59-27690), the front-to-back length of the tilling section tends to be long.

It is oscillated to crush the soil below the bottom surface of the tilled soil by the tilling claws (3). The oscillation transmission of this core soil claw (4) is performed while maintaining a constant relationship with the tilling rotation transmission of the tilling claw (3), and the tilling claw (3) approaching this core soil claw (4) But, the core clay nail (4) swings (a)! !
When the core soil claw (4) can be rotated outside m, the core soil claw (4) is oscillated (a) within the rotational diameter (b) of the tilling claw (3), so that the tilling claw (3) and the core soil claw ( 4) The tilling action and crushing on the core can be performed smoothly with little interference without polymerization or contact with the tilling claws (3).
Since it is interlocked with the core soil claw (4), it is hard to get out of order, can be maintained accurately, and the structure is simple.

A side transmission case (9) is provided at the negative end of the frame (8), which accommodates a transmission mechanism that transmits power from the input shaft through an internal gear transmission mechanism to the tilling shaft (2). A side arm (lO) is provided at the side end to bear the other end of the tilling shaft (2), and the tilling shaft (2) is connected to both measuring section transmission cases (9) and the bottom of the side arm (10). The shaft is mounted between the lower ends of the shaft to transmit rotation. Cultivating claws (3)
are placed on the tilling shaft (2), but the tilling claws (3) in the center of the left and right
) is longer than the other tilling claws (3) and can be used to till deeply.

2) A bell crank (13) is provided around the bell crank (13), and is detachably attached to the bell crank (13) using a pin (14) or the like. The core soil claw (4) consists of a plate-shaped arm with a narrow left and right width and a resistance plate at the lower end of the arm, and by swinging in the front and back direction, the core soil at the bottom of the tilled soil ± (JJJI-I!IL)
Crush this plow while going undercover. The structure of this oscillation transmission is such that the rotation cam (1B) is transmitted from a part of the transmission mechanism to the tilling shaft (2) in the transmission case (5) through the transmission mechanism (15) using gear transmission. (1B) is brought into contact with the roll (17) at the upper end of the bell crank (13), and the rotation of the rotary cam (16) causes the core claw (4) to swing back and forth (A).
