Description

[Detailed Description of the Invention] The present invention relates to a bucket for a work vehicle equipped with a scarifier.

Conventionally, when using a work vehicle to treat earth and sand on a hard ground, it has been either to use a work vehicle that has the structure of a ripper vehicle or to use a ripper installed on a general vehicle. However, it is generally uneconomical to purchase a work vehicle with the structure of a ripping vehicle completely separately from a general work vehicle and keep it in your possession at all times, considering the frequency with which it is constantly operated for the purpose of excavation work.

In addition, it has often been done to reinstall Ritupas scarifiers on existing general work vehicles, but in addition to the scarifier itself, it is necessary to install new hydraulic system piping and hydraulic cylinders, etc., which reduces the installation cost. It is quite expensive. Therefore, there has been a need for new, effective and economical equipment for excavating hard ground.

The present invention was made to eliminate the above-mentioned drawbacks of the conventional technology.For this purpose, the present invention provides a bucket to be used attached to a working vehicle, which extends vertically along the back of the bucket and whose claw tips are located below the bottom of the bucket. A plurality of protruding scarf wires are removably attached via pins to brackets fixed to the back surface of the bucket, respectively, and when the scarf wires are not in use, the tips of the claws are directed upward, and the brackets and pins are used to guide the scarf wires along the back surface of the bucket. This allows the scarifier to protrude downward from the bottom of the bucket when performing ripping work, and to hold it on the back of the bucket with the claw tip facing upward when used as a regular bucket. This bucket bag has a simple structure and can be manufactured at low cost. Furthermore, by attaching the scarifier to the back of the bucket, the ripping work can be carried out at the front of the vehicle body, so the work can be carried out while fully checking for obstacles that may damage the scarifier.

Hereinafter, the content of the present invention will be explained in detail along with the embodiments shown in the accompanying drawings.

FIG. 1 is a perspective view of a bucket 3 for a work vehicle in which the mechanism of the scarifier 1 is provided on the back. It is held in the vertical direction by pins or bolts 9 and 11 with the tip of the claw protruding downward from the bottom of the bucket.

By moving forward a work vehicle equipped with a bucket with a scarifier installed in the position shown in Figure 1, it is possible to excavate even very hard ground and loosen the soil.

It is necessary to provide a plurality of the scarifier wires 1 on the back surface of the bucket 3. This is because the excavating capacity of a single excavator is small, and the processing area and the amount of soil excavated per one forward movement of the working machine are too small, resulting in poor efficiency.

In order to attach the mechanism of the scarifier 1 to the back of the bucket 3, the bucket is used for ripper work and has to be attached to the bracket 7 to handle the moment load generated on the scarifier for digging up soil.
It is necessary to provide some reinforcement to the extent that it can endure.

Next, when scooping the loosened soil with a bucket, if the scarifier is installed in the position shown in Figure 1, it will get in the way and the scooping operation will be almost impossible.
Therefore, in the bucket of the present invention, when the scarifier is not in use, the tip of the claw may be removed, or if there is a sufficient distance between the work vehicle body and the bucket, the claw may be left attached to the scarifier and the tip of the claw should be directed upward. It was designed so that it could be held along the back of the bucket.

The manner in which the scarifier is held along the back surface of the bucket with the tip of the claw facing upward will be specifically explained. First, as a means, as shown in FIG. 2, which is a side view of the bucket tote of the present invention,
Remove the lower pin or bolt 11 of the pins and/or bolts 9 and 11 installed through the bracket 7 fixed on the back of the scarifier, and use the pin or bolt 9 near the rear end of the scarifier as the axis. Turn the scarf eye so that the claw tip 5 faces upward as shown by the dotted line 22 in FIG. Can be retained. However, in order for this rotational operation to be possible, it is necessary that there is a space between the bucket 3 and the work vehicle main body (not shown) within the range of the dotted line 21 or 22 shown in FIG. If that space is dotted line 22
If it is within the range, the scarf eye can be rotated upward without removing the claw tip 5. If there is only a space around the dotted line 21, it is necessary to remove the claw tip once in order to rotate the scarf eye 1 upward. becomes.

Figure 3 shows another mode of holding the scarf eye along the back of the bucket when the scarf eye is not in use, and 41 and 43 are used to attach bucket support arms (not shown) protruding from the main body of the work vehicle. It's a bracket. This embodiment differs from the case shown in FIG. 2 by removing all the pins and/or bolts 9, 11 for attaching the scarifier 1 when moving the tip of the scarifier claw in the upward direction. ', and with the scarf eye at position 1', align the sled of the scarf eye with the sled at the top of the back of the bucket and tighten the pins or bolts 9 and 13 again to set the scarf eye 1'.
hold.

It is necessary to use this holding mode when the space between the bucket and the vehicle body is small.

The effects of the present invention described above are as follows.

Compared to the original ripping truck or the case of reattaching the scarfing wire to a general work vehicle, the use of the bucket with the scarfing iron of the present invention is extremely economical, as the cost is a fraction of that of other methods. Civil engineering work or agricultural work can be performed much more economically than before.

In addition, in conventional ripping operations, the scarfing iron is installed at the rear of the working vehicle, making it difficult for the operator of the vehicle to constantly monitor the work situation, but the bucket cart with scarfing iron of the present invention is installed at the front of the working vehicle. Therefore, in addition to monitoring the work status, it is also possible to easily identify obstacles that may damage the ripper mechanism, which has great effects such as preventing vehicle breakdowns or accidents. .
