Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a tillage device in which a wire is stretched between claw holders around a claw shaft.

[0002]

2. Description of the Related Art Conventionally, a rod is provided on the outer periphery of a claw shaft to prevent the claw holder from being wound around a straw.

[0003]

[Problems to be Solved by the Invention] However, if the rod has a predetermined strength, the diameter becomes large, so that straw cannot be cut. It had problems such as bending due to impacts.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised so as to solve such a problem and to be suitably implemented. For this reason, a plurality of plowing claws are provided on a plurality of pawl holders provided on the outer periphery of a pawl shaft. In a tillage device configured to be detachably attached, a tip end side of a wire is fixed and stretched so that the wire is stretched between adjacent claw holders.

[0005]

Therefore, if the distal end of the wire is fastened so that the wire is stretched between the adjacent claw holders, the straw can be effectively cut by the stretched wire. Can be prevented from winding.

[0006]

FIG. 1 is a front view showing a part of a tillage device. Claw shafts 1 and 1 are respectively provided on both sides of a lower part of a tillage case 7 erected at a rear portion of a tiller, and the claw shafts are provided. A large number of claw holders 2 each having a lateral hole 4 as an axial hole can be fitted on the outer periphery of the cultivating claw 3 having a lateral hole 5 as a hole. A wire 6 which is an example of a cord having the same structure as the conventional structure but having a locking body 6a on one end side is connected to the lateral hole 4 of each claw holder 2 adjacent in the axial direction and the claw holder 2 respectively. The tip of the wire 6 extending from the claw holder 2 at one end of the claw shaft 1 to the claw holder 2 at the other end so that it can be inserted into the lateral hole 5 at the base of each fitted tillage claw 3, Wire 6 between adjacent nail holders 2
As shown in FIG. 3, they are fastened to each other by a locking tool 8 and attached to each other using three wires 6.

Accordingly, the base of the plowing claw 3 is inserted into each of the claw holders 2, and each of the claw holders 2 adjacent to each other in the axial direction from the claw holder 2 on one end of the claw shaft 1 to the claw holder 2 on the other end is cultivated. The wires 6 are sequentially inserted through the lateral holes 4 and 5 of the hook 3 so that the locking body 6a abuts the claw holder 2 at one end and the wire 6 is stretched between the adjacent claw holders 2. When the distal end of the wire 6 is pulled out from the claw holder 2 at the other end, and the distal end of the wire 6 is fastened by the locking tool 8, the plurality of tillage claws 3 can be easily attached. When the wire 6 is pulled out and removed, the wire 6 can be easily removed, and the wire 6 is stretched between the claw holders 2 and 2 adjacent in the axial direction. To reduce the amount of straw and grass wrapped around Can.

[0008]

As described above, according to the present invention, in a tillage device in which a tillage claw 3 is detachably attached to a plurality of claw holders 2 provided on the outer periphery of a claw shaft 1, adjacent claw holders 2, 2 are provided. Since the wire 6 is stretched by fastening the distal end side of the wire 6 so that the wire 6 is stretched therebetween, the straw can be effectively cut by the stretched wire, and the deformation due to the impact of the earth mass can be prevented. This wire has the characteristic that the winding of straw can be prevented.
