Abstract

PURPOSE:To rapidly treat broken objects by a bucket by a method in which a breaker is rotatably attached to a box-type bucket body having an opening on its front side, and objects are broken into small pieces between the breaker and the bucket body by extending or contracting an liquid-pressure cylinder. CONSTITUTION:When the liquid-pressure cylinder 18 of a bucket 2 mounted on a power shovel or back hoe is extended, a breaker 16 is turned and objects are broken into small pieces by compressive force and shearing force between a fixed bit 32 and a movable bit 34. After the breaking work, the liquid-pressure cylinder 18 is contracted and broken objects are loaded on a truck, etc., by the bucket 2. Thus, breaking concrete structures or coal, loading the broken objects, and excavation can be attained simply by mounting the bucket 2 on a construction machine.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for rapidly processing materials to be shredded using packets.

Demolition of concrete structures, peeling of road pavement layers, and crushing of rocks in quarries are carried out using a crusher mounted on a power shovel like a conventional breaker, and a tractor/yover or packet dozer is used to load the materials to be crushed. etc. are often used. Such work sites are generally small and inconvenient, and are dangerous as they may cause problems when operating and repositioning various construction machines, and may cause collisions. For this purpose, if one power shovelni shredding machine and packets are loaded alternately, concrete pieces or crushed rocks that are too large to be directly disposed of or reused after being shredded by the shredding machine are discovered during loading. The work may not proceed quickly as it will be necessary to reinstall the splitter on the power shovel. Replacing packets with a heavy-duty splitter at an inconvenient work site is surprisingly time-consuming and can easily lead to unexpected accidents.

The present invention has been proposed to improve the aforementioned problems associated with concrete demolition or rock crushing. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method for quickly processing materials to be crushed by performing subdivision operations, excavation and loading operations without replacing packets.

The crushing member rotates at position 1 indicated by the two-dot chain line in Figure 2 and Figure 4, and crushes the object to be crushed between the fixed bit part and the movable bit part mainly by applying compressive force and shear force. divide. When the small-splitting work is completed, the hydraulic cylinder is compressed to stop the crushing member at the solid line position shown in Figure 2 or Figure 4.
Then, the material to be crushed after being divided into small pieces using packet 2 may be loaded onto a truck or the like. If an object to be crushed that is too thick appears during the loading operation, the hydraulic cylinder 18 is telescopically operated again to break the object into small pieces with the crushing member 16, and then the loading operation using the packets 2 can be resumed. Also packet 2
During excavation work, the crushing member remains stationary at the solid line position in FIG. 2 or 4. If a small protrusion such as a concrete material appears during excavation work and the packet 2 becomes stuck, the packet body 14 is placed over the protrusion and the crushing member 1 is removed.
6, the excavation work can be easily completed.

The packet 77 mounted on the power shovel 76 in FIG. 6 has the same function as the packet 42 shown in FIG. 4, and includes a packet main body 78, a crushing member 80, and a hydraulic cylinder 82. A parallel bracket part 84 is fixed to the upper wall of the packet main body 78, and the arm tip of the power shovel 76 and the packet link are respectively pivotally attached to both bracket parts. Similar to the packet 42 of FIG. 4, the crushing member 80 is pivotally mounted within the packet body 78 and is pivotally mounted at the rear upper portion of the packet body 78 to the rear tube portion of the hydraulic cylinder 82, and A piston rod is pivotally connected to the lower front end of the crushing member 80.

Further, the lower front end portion of the crushing member 80 constitutes a movable bit portion 86, and a fixed bit portion 88 is made to protrude in correspondence with the movable bit portion 86 in front of the lower wall of the packet body 78. When the object to be crushed is a thin concrete structure 90 as shown in FIG.
After covering it, the hydraulic cylinder 82 is expanded and contracted to break it into pieces with the crushing member 80. If the object to be crushed is a road pavement layer, it may be scooped out with the packet 77 and then divided into small pieces with the crushing member 80. After this, loading work or excavation work may be performed in the same manner as described above.

According to the method of the present invention, by simply installing a bucket on a single construction machine, it becomes possible to divide concrete structures and rocks into small pieces, as well as load and excavate them. It is safer because it avoids collisions and reduces contact accidents, and it is also advantageous in terms of machine equipment costs.

In addition, in the method of the present invention, small breakers such as breakers are used.
Even if there are rocks or conocrete fragments that are too large after being crushed by blasting, they can be broken into small pieces at the same time as loading, so there is no need to install a separate crusher or reinstall the crusher on the construction machine. Therefore, there is no delay in processing the materials to be crushed due to the intervention of temporary subdivision work. In addition, it is easier to reduce the rock and concrete pieces to a certain size than with a large crusher, so crushed concrete pieces that were previously discarded can be used as foundation material for construction. Reuse it as a substitute for Zan or Barasu, or 9. It is also possible to dispose of the waste directly to a designated treatment plant. Even if protrusions such as concrete pieces appear or a road surface pavement layer is present during excavation work using this sprouting method, the protrusions and pavement layer can be crushed without interrupting the excavation work, resulting in rapid operation. It also has the advantage of being able to accomplish excavation work.
