Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a rotary tilling device in which a large number of tilling claws are arranged on the outer peripheral surface of a tilling shaft.

2. Description of the Related Art Conventionally, a plowing pawl such as a ratchet or an L-shaped pawl attached to the outer peripheral surface of a plowing shaft is curved leftward with respect to the blade surface and curved rightward with respect to the blade surface. There are two types of tillage nails, the tillage nail.

Here, at the time of attaching the tilling claw to the tilling shaft, the tilling claws are arranged at equal intervals along the circumferential direction of the tilling shaft, and two or more tilling claws are simultaneously driven into the cultivating soil. Prevents vertical vibration.

Further, a left-turning tilling claw and a right-turning tilling claw are arranged so as to be alternately driven into the cultivated soil, and a rotary claw generated by continuously driving the tilling claw curved in the same direction into the cultivating soil. The left and right vibrations of the tiller are prevented.

In addition, when performing flat tillage and ridge tillage using one rotary tiller, the tiller claws may be exchanged, or the tiller claw may be attached to the empty tiller claw attachment portion that is previously formed on the outer peripheral surface of the tiller shaft. I am changing.

Problems to be solved by the invention When the tilling claws are replaced for performing ridge tillage, the tilling claws curved in the same direction are continuously driven into the cultivated soil, and the rotary tiller vibrates in the lateral direction. There is a drawback that.

Even when the tilling claw is replaced with the empty tilling claw attachment portion, similarly, the tilling claws curved in the same direction are continuously driven into the cultivated soil, and the rotary tiller vibrates in the left and right directions.

Means for solving the problem While arranging a large number of plowing pawls on the outer peripheral surface of the plowing shaft at equal intervals along the circumferential direction of the plowing shaft, the plowing pawls curved to the left and curved to the right In a rotary cultivating device in which the cultivating pawls are arranged so that the cultivating pawls are alternately driven into the cultivated soil, at least a plurality of the cultivating pawls are detachably provided, and a vacant cultivating pawl attachment for replacing the detachable cultivating pawls is attached. A part is formed on the outer peripheral surface of the cultivating shaft, and when the cultivating claw is replaced with the empty cultivating claw attaching part, the cultivating claws are arranged at equal intervals along the circumferential direction of the cultivating shaft, The empty tillage claw mounting portion is arranged so that the tilling claw curved to the left and the tilling claw curved to the right are alternately driven into the cultivated soil.

Action When a detachable tiller claw is replaced with an empty tiller claw attachment part, since the tiller claws are arranged at equal intervals along the circumferential direction of the tiller shaft, two or more tiller claws are driven into the soil at the same time. Vibration in the vertical direction caused by the vibration is prevented. Further, when the detachable tilling claw is replaced with the empty tilling claw attachment portion, the tilling claw curved to the left and the tilling claw curved to the right are arranged to be alternately driven into the cultivated soil. Therefore, vibration in the left-right direction caused by continuously driving the tilling claws curved in the same direction into the cultivated soil is prevented.

Embodiment An embodiment of the present invention will be described with reference to the drawings. A plurality of tillage claws 2 to 15 are detachably arranged on a tiller shaft 1 which is rotatable around its axis. These tillers 2-15 are the second
As shown in the figure, they are arranged at equal intervals along the circumferential direction of the cultivating shaft 1, and two pieces are arranged in the same plane of rotation. Further, as shown in FIGS. 2 and 3, with the rotation of the tiller shaft 1, the tiller claws 3, 5, 7, which are curved leftward,
9,11,13,15 and right-handed tilling claws 2,4,6,8,10,12,14
So that the and are alternately driven into the cultivated soil.
Is provided.

Furthermore, four empty tillage claw mounting portions 16 to 19 are provided on the outer peripheral surface of the tiller shaft 1. 4 and 5 replace the tilling claw 10 with the empty tilling claw mounting part 16, the tilling claw 7 with the empty tilling claw mounting part 17, the tilling claw 6 with the empty tilling claw mounting part 18, and the tilling claw 11 It shows a state in which is attached to the empty tillage claw attachment portion 19.

In such a configuration, FIGS. 1 to 3 show an arrangement state of the tilling claws 2 to 15 in the case of performing flat plowing.
Since the plowing pawls 2 to 15 are arranged at equal intervals along the circumferential direction of the plowing shaft 1, no two or more plowing pawls are simultaneously driven into the soil, and two or more plowing paws are simultaneously driven into the soil. In this case, the vertical vibration of the rotary cultivator caused by the above situation is prevented. Furthermore, since the plowing pawls 2 to 15 are arranged so that the plowing jaws curved to the left and the plowing jaws curved to the right are alternately driven into the cultivated soil, the plowing pawls curved in the same direction are continuous. The horizontal vibration of the rotary tiller, which is generated when driven into the cultivated soil, is prevented.

Next, FIG. 4 and FIG. 5 show the arrangement state of the tilling claws 2 to 15 when performing ridge cultivation. Since the tilling claws 2 to 15 are arranged at equal intervals along the circumferential direction of the tilling shaft 1,
At the same time, two or more tillage claws are not driven into the cultivated soil, and vertical vibration of the rotary tiller is prevented. In addition, the plowing claws 2 to the left and the plowing claws curved to the right are alternately driven into the cultivating soil.
The provision of 15 prevents the rotary tiller from vibrating in the left-right direction.

Effect of the Invention According to the present invention, when the tilling claw is replaced with the empty tilling claw mounting portion as described above, the tilling claws are arranged at equal intervals along the circumferential direction of the tilling shaft and curved to the left. By arranging the empty tillage claw attachment part so that the claw and the right-sided tillage claw are alternately driven into the cultivated soil, even when replacing the tillage claw with the empty tillage claw attachment part The vertical vibration of the rotary tiller is prevented by preventing two or more plowing pawls from being simultaneously hammered into the cultivated soil, and that the plowing pawls curved in the same direction are continuously hammered into the cultivating soil. By preventing it, it is possible to prevent the rotary tiller from vibrating in the left-right direction.
