Abstract

PROBLEM TO BE SOLVED: To provide a cultivating pawl setting device, which allows the cultivating pawls of the same length to be easily controlled and to cultivate a field demarcated by a ridge of any shape. SOLUTION: This cultivating pawl setting device is for a rotary cultivating device whose cultivation axis A is provided with a number of pawl holders 2 radiating from the outer periphery in the side view to hold the cultivating pawls 1, wherein each cultivating pawl 1 is set on each pawl holder 2 via an extension pawl holder 3 which can be freely attached to the pawl holder 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tilling claw mounting device which can be mounted on a tilling shaft so that a cultivating locus can be changed using tilling claws of the same length.

[0002]

2. Description of the Related Art Conventionally, in a tilling shaft of a rotary tilling device in which a large number of claw holders which can be fitted and fitted with shank portions of a tilling nail are radially arranged on the outer periphery in a side view, middle tillage and weeding adapted to a ridge shape. When performing tillage, attach a long tilling nail to the claw holder at the center to increase the tillage action locus, and to the left and right claw holders, use a tillage claw whose tillage action locus gradually decreases outward. Each had to be attached.

[0003]

Therefore, it is necessary to prepare a large number of tilling claws having different lengths, which is uneconomical. Moreover, the types of tilling claws increase, and it is difficult to manage the tilling claws. The problem arises.

[0004] Accordingly, an object of the present invention is to use a tilling claw of the same length, to suitably change the trajectory action locus according to an arbitrary ridge shape, to easily manage the tilling claw, An object of the present invention is to provide a tilling claw mounting device in which claw management can be easily performed.

[0005]

According to the present invention, there is provided a tilling claw mounting device, comprising: a plurality of claw holders to which tilling claws can be mounted; Is provided with an extendable claw holder which can be freely connected to the crawler, and the tillage claw can be attached to the claw holder via the extension claw holder.

According to the above construction, the tilling claw can be directly attached to the claw holder or can be attached via the extension claw holder using the same length of the tilling claw. It is possible to obtain the tillage action locus according to the shape, and to easily manage the tillage claw,
The management of the tilling nail becomes good.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a side view of a part of a rotary tilling device. In the rotary tilling device, a shank portion 1a of a tilling claw 1 is provided on the outer circumference of both tilling shafts A driven by a center drive type from a tilling case B. A large number of claw holders 2 having concave portions 5 to be fitted are radially arranged on the outer periphery in a side view. The tilling claw 1 is attached by tightening the nut 9 to the tip.

An extension claw holder 3 having the following structure is connected to the claw holder 2 as necessary. That is, the tilling claw 1 is provided at one end of the extension claw holder 3.
The shank portion 1a can be fitted, and a recess 10 having substantially the same shape as the recess 5 of the claw holder 2 is formed. On the other end side, the recess 10 of the claw holder 2 can be fitted. A projecting portion 4 having substantially the same shape as the shank portion 1a is formed, and a lateral hole 11 into which the bolt 8 can be inserted in a direction crossing the concave portion 10 and the projecting portion 4 of the extension claw holders 3 and 3a; 12
Is formed. In addition to the extension claw holder 3, a plurality of extension claw holders 3a and 3b having the same length from one end surface to the other end surface are prepared in the same manner.

Therefore, since it is sufficient to arrange a large number of tilling claws 1 having the same length as the tilling nails 1 used in the rotary tilling apparatus, the tilling nails can be easily managed, and workability of the tilling nail management work can be improved. When the shank 1a of the tilling claw 1 is fitted into the concave portion 5 of the claw holder 2 and the bolt 8 is inserted and the nut 9 is tightened, the tilling claw 1 can be directly attached to the claw holder 2. In addition, the protrusion 4 of the extension claw holder 3 is fitted into the recess 5 of the claw holder 2 and the bolt 8 is inserted and tightened with the nut 9, and the shank 1 a of the tillage claw 1 is fitted into the recess 10 of the extension claw holder 3.
Is fitted, the bolt 8 is inserted and the nut 9 is tightened, and the tilling claw 1 can be attached to the claw holder 2 via the extension claw holder 3.

In this manner, as shown in FIG. 3, when the tilling nails 1 are directly attached to all the nail holders 2, the tilling action trajectories of all the tilling nails 1 become the same R1, as indicated by C1. 4 and 5, and the cultivating claw 1 at the center is extended through extension claw holders 3, 3a, 3b having different lengths, as shown in FIGS. When the tilling claw 1 is directly attached to the claw holder 2, respectively, the tilling action trajectory of the cultivating claw 1 at the center is R2, R3.
, And can be adapted to the ridges having the shapes indicated by C2 and C3, so that middle plowing and weeding can be suitably performed.

[0012]

As described above, according to the present invention,
By using tilling nails of the same length, the tilling nails can be directly attached to the nail holder or attached via the extension nail holder, so that the trajectory action locus can be obtained according to any ridge shape, making it easy to manage the tilling nails The present invention can provide a tilling claw mounting device which can be performed easily and has good tilling claw management.
