Description

[Detailed Description of the Invention] The present invention relates to an improvement of a packet used in a hydraulic excavator or the like.

Traditionally, oil and pneumatic breakers have been used for building demolition and road surface peeling, and recently, many hydraulic crushers have appeared that are installed on the end of the hydraulic excavator's arm instead of a packet as a vibration-free and noise-free demolition machine especially for urban civil engineering work. However, in order to load crushed concrete, asphalt, etc. into a dump truck, a hydraulic excavator equipped with a packet for loading must be brought to the site, or a hydraulic excavator attached to the end of the arm of hydraulic excavator 1, as shown in Figure 1, is required. The hydraulic crusher 2 is removed from the arm 3 of the hydraulic excavator 1 by removing the pin 4 at the tip of the arm 3 and simultaneously removing the drive pressure oil hose 5 of the hydraulic crusher 2. Thereafter, a regular packet 6 shown in FIG. 2 was attached to the tip of the arm 3 by inserting a pin 4, and crushed concrete, asphalt, etc. were loaded onto a dump truck.

However, it took a lot of time to replace the attachments between this hydraulic crusher and the packet, and the process had to be done manually.

Therefore, a hydraulic crusher attached to the arm of a hydraulic excavator is used to dispose of concrete and asphalt residue (dump loading work) that occurs at the same time as building demolition and road surface peeling. It became necessary to save work time and labor costs by allowing ordinary packets to be easily attached and detached without removing them.

The present invention meets this need.The purpose of the present invention is to eliminate the above-mentioned drawbacks and provide a packet that can be easily attached to and detached from a hydraulic crusher attached to the arm of a hydraulic excavator. The feature of this product is that a clamping bracket is formed on the upper back of the packet body, which can be clamped by the meshing action of a hydraulic crusher, in which a pair of crushing teeth are engaged by the action of a hydraulic cylinder. The packet can be attached using the crushing force of a pair of crushing teeth of the hydraulic crusher without removing the hydraulic crusher which is rotatably attached to the tip via a pin.

An embodiment of the present invention will be explained according to FIGS. 3 and 4.

FIG. 4 is a side view of the packet according to the present invention, and FIG. 3 is a side view showing the packet attached to a hydraulic crusher attached to the arm of a hydraulic excavator.

In FIG. 4, 7 is a clamping bracket with a rectangular cross section formed on the upper back of the main body of the packet 6 (on the side opposite to the opening side), and is arranged between the left and right mounting brackets 10 extending to the back. .

In FIG. 3, members that are the same as conventional members are designated by the same numbers, and their explanations will be omitted.

8 is a crushing tooth part of the hydraulic crusher 2, and the crusher main body 11
The upper crushing tooth portion 8a is
The lower crushing teeth 8b are engaged with each other.

The lower crushing tooth portion 8b is connected to the lower side of the crusher main body 11, and the upper crushing tooth portion 8a is automatically supported by the crusher main body 11, and a hydraulic cylinder is installed between the main body 11 and the upper crushing tooth portion 8a. a
The upper part of the crusher main body 11 has a mounting bracket 12 that can be attached to the tip of the arm 3 of the hydraulic excavator 1.
are connected at.

For building demolition and road surface peeling, only the hydraulic crusher 2 is attached to the tip of the arm 3 of the hydraulic excavator 1 and the work is carried out.

The concrete and asphalt residues generated from this work are disposed of on a hydraulic crusher 2 rotatably attached to the tip of the arm 3 of the hydraulic excavator 1 via a pin 4, as shown in Fig. 3. The clamping bracket 7 of the packet 6 is generated by the crushing force of the hydraulic crusher 2 at the lower crushing teeth 8 a and 8 b, that is, the engagement force between the crushing teeth 8 a and 8 b generated by extending the hydraulic cylinder 9. The crushed concrete or asphalt, etc., is loaded onto a dump truck by operating it in the same way as packet excavation work with a normal hydraulic excavator 1, and replacing the packet with the conventional method requires no pin removal. It has a simple configuration and saves labor.

As described above, according to the present invention, it is possible to attach packets by simply engaging the hydraulic crusher, which is attached to the end of the arm of the hydraulic excavator and engages the upper and lower crushing teeth by operating the hydraulic cylinder, without having to remove the hydraulic crusher. It saves labor in building demolition and road stripping work, and makes it easier to remove crushed materials during crushing work.
