Description

[Detailed description of the invention] This invention relates to a protective body extension to be attached to a ripper shank. This is based on the fact that the tip 2 is fixed to one end of the ripper shank 1, which enters the ripper shank quite deeply.

In conventional ripper assemblies, the portion of the ripper shank between the tip and the work vehicle contacts the ground and becomes worn and corroded during long-term use.

Traditional protectors have been designed to protect a specific length of the shank.

The purpose of this invention is to provide a protective extension that covers selected portions of the ripper shank and protects the shank from wear and corrosion during use of the ripper.

That is, the present invention has a protector extension fixed to the shank protector and arranged to engage and protect the shank, and the shank has a mounting hole for fixing the protector extension. The gist thereof is a ripper shank protector extension, characterized in that it has no.

Even more specific advantages of the invention will become apparent in the following description with reference to the accompanying drawings.

In the drawings, the ripper chassis 1 has one end connected to the work vehicle and the other end connected to the tip 2.

The ripper moves underground from left to right in Figure 1, with the tip 2 and the ripper shank below the ground.

The ground wears and corrodes that part of the shank that is in contact with the ground.

The part of the upper shank which is likely to come into contact with the ground during operation of the knob is covered with a shank protector 3 at its leading edge.

The protector 3 has a leading edge 4 which covers the leading edge of the ripper shank 1 and is U-shaped to engage with the shank 1.

The protection body 3 is provided with a hole 5 which is concentrically aligned with the hole 6 in the extension piece 7 of the protection extension 8 on the side opposite the end of the chip 2.

The extension 8 is attached to the protector 3 and is U-shaped like the protector 3 so as to engage the shank 1.

Because the holes 6 and 5 are aligned, the extension 8 can be easily and quickly attached to the protection body 3.

The front edge 4 of the protector 3 and the front edge 4a of the extension part 8 are connected to the protector 3.
and is thicker than the rest of the extension 8 and is shaped with protrusions to assist in digging the ground.

In this way, the extension part 8 engages with the shank 1 at the U-shaped part, and since the shank 1 does not have a mounting hole, it can be installed easily.
The trouble of disassembly can be saved, the number of parts can be reduced, and there is no influence of stress concentration, so there is no risk of early fatigue or breakage.
