Description

[Detailed Description of the Invention] This invention relates to a tine tipping device installed in a soil stirring machine such as a load stabilizer.

For example, in a typical configuration of a road stabilizer, as shown in FIG. 1, a stirring device 3 is supported by a frame 2 at the rear end of a stabilizer main body 1 made of a caterpillar type traveling machine. It is equipped with an operating power that allows it to move vertically and horizontally.

This stirring device 3 is provided with tines 4 for rotating around a horizontal axis to stir the soil, and tine blades 5
A tip 6 is attached to the tip of each arm of the soil, which moves through the soil to perform crushing and mixing operations.

It goes without saying that the tip of the tip gradually wears out as the tine is used over time, and if the protruding dimension of the tip from the tip of the arm decreases beyond its effective state due to wear, the tip will wear out. The crushing and mixing operability fell below the practical range, and therefore, the life of the tip was considered to be the period in which the degree of wear exceeded the effective amount.

By the way, in the structure of conventional chip devices, the chip is permanently attached to the mounting surface of the arm, so when the chip reaches the end of its lifespan, it is replaced with a new chip. There was the hassle of having to make many arrangements and preparations.

The present invention has been made to eliminate such troubles, and the purpose of the present invention is to easily correct the protruding dimension of the insert when the degree of wear of the insert exceeds the effective tolerance. An object of the present invention is to provide a tine tipping device that can be obtained.

The present invention will be explained below based on three illustrated embodiments.

In the chip device of the first embodiment, as shown in FIGS. 2 to 4, one side of the tip end of the arm plate 7 of the tine blade, that is, the lower end of FIG. A mounting seat 8 made of a block having a U-shaped cross section is welded to the lower end of the surface 7a, and at a position close to the mounting seat 8 on an extension of the center line of the mounting seat 8, that is, on the locking line, as will be described later. A locking hole 7b is drilled through which a mounting bolt 9 as a mounting tool passes.

On the other hand, the chip 10 made of a rectangular thick plate has two mounting holes 10a and 10b, through which the mounting bolts 9 pass, bored at two locations on the center line, that is, the mounting line, of the upper half of the chip. 10 is inserted into the longitudinal space between the mounting seat 8 and the mounting surface 7a, the intermediate part thereof is supported by the mounting seat 8, and the mounting hole 10 is inserted through the mounting hole 10a and the locking hole 7b. It is fixed to the arm plate 7 by tightening the bolt 9 with a nut 11.

Note that the interval between the surface mounting holes 10a and 10b is set to be equal to the chip activation e.

In the tip device of the first embodiment configured in this way, when the degree of wear at the tip of the tip 10 reaches the effectiveness e due to the cumulative use period, the tip 10 is removed as follows.
It is possible to correct the protrusion dimension of.

That is, as shown in FIG. 5, after removing the bolt 9, the chip 10 is shifted downward by an amount e, and then,
If the bolt 9 is inserted into the upper mounting hole 10b and the locking hole 7b and the nut 11 is tightened, the protrusion dimension of the worn edge 10C will be equal to the protrusion dimension of the tip 10 when new (see Figure 2). Become.

From this, the service life of the chip 10 is 2
Stretch it twice.

Next, in the chip device of the second embodiment, as shown in FIG. Similarly, it is supported by the mounting seat 8 and is fixed to the arm plate 7 with a bolt 9 passing through the mounting hole 12a and the locking hole 7b.

In the tip device of the second embodiment configured as described above, when the degree of wear reaches the activation e, the mounting direction of the tip 12 is reversed as shown in FIG. It is possible to correct.

That is, after removing the tip 12, the wear edge 12 is removed.
All you have to do is turn b up and tighten again with bolt 9. Therefore,
The service life of the chip 12 is doubled compared to the conventional one.

In addition, in the chip device of the third embodiment, as shown in FIG. 10
a, 10b, and 10C are bored, and the chip 13 is fixed to the arm plate 7 with a bolt 9 passing through the attachment hole 10C and the locking hole 7b.

In the tip device of the third embodiment configured as described above, it is possible to correct the protrusion dimension of the tip 13 three times as described below each time the degree of wear reaches the validation e.

(a) First time (see Figure 7): Shift the chip 13 downward and tighten the central mounting hole 10a with the bolt 9.

In this way, the worn edge 13d protrudes to its original size.

(b) Second time (see Figure 7C) Turn the tip 13 over so that the worn edge 12e worn twice as much as the activation e is on top, and the lower mounting hole 10C
Tighten with bolt 9.

In this way, the unused end of the chip 13 protrudes downward.

(C) Third time (see FIG. 7C) Shift the chip 13 downward and tighten the mounting tag 10a in the center with the bolt 9.

In this way, the worn edge 13f protrudes to its original size.

By carrying out the above three correction operations, the service life of the chip 13 is extended four times compared to the conventional one.

In addition, if the tip 13 is slid down and corrected again after the above-mentioned first correction and after the third correction, the service life can be extended six times.

By the way, in addition to the three embodiments mentioned above, as a structure similar to the third embodiment, if the longitudinal dimension of the chip is made as long as possible and the number of holes for mounting holes is increased, the service life can be further extended. be able to.

It goes without saying that similar correction operations can also be carried out by increasing the number of locking holes in the arm plate 7.

As described above, according to the tine tipping device according to the present invention, at a required point during the tine usage period,
The structure is such that the protruding dimensions of the chip can be corrected by changing the mounting position of the chip on the vane arm or changing the mounting direction by tightening and changing the chip mounting bolt as a mounting tool, thereby reducing the lifespan of the chip. This has the effect of making the tines easier to maintain.
