Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for rapid VC processing of materials to be shredded by packets.

Demolition of concrete structures, peeling of road pavement layers, and rock crushing at quarries are conventionally carried out using a crusher mounted on a power shovel, like a conventional braking machine, and tractor excavators, bucket dozers, etc. are used to load the materials to be crushed. Often used.

Such work sites are generally small and inconvenient,
It is also dangerous as it can cause problems and collisions when operating and repositioning various types of construction machinery. For this reason, if a single excavator is equipped with a DL refilling machine and a packet alternately, it can be directly disposed of or reused after being shredded by a crusher. However, it may be necessary to reinstall the sizing machine on the power shovel, which may prevent the work from proceeding quickly. At an inconvenient work site, replacing packets with a small-sized splitter that weighs a certain amount takes a surprisingly long time and is likely to cause an unexpected accident. The present invention has been proposed to improve the above-mentioned problems regarding concrete demolition or rock crushing. SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method for rapidly processing materials to be crushed by carrying out rig work, excavation and loading work without replacing packets. In the packet used in the present invention, the packet main body has an approximately box-like shape with an open front portion, and the packet body itself has a well-known shape.

The crushing member has a rear portion rotatably attached to the packet body at the H-crotch, has a predetermined width, and has a side surface approximately L-shaped.
It may be Ξ-gonal or linear. The hydraulic cylinder also has a rear end pivotally connected to the bucket main body, and a piston rod of the cylinder pivotally connected to the crushing member. The crushing member and the hydraulic cylinder are usually installed parallel to both side walls of the bucket main body, and may be arranged close to the longitudinal center or one side wall of the bucket main body when viewed from the front. The construction machine on which this bucket is mounted is preferably a shovel-type truck having an arm and a boom, such as a power shovel or a shovel. The hydraulic pressure source of the hydraulic cylinder that drives the crushing member is convenient for work when used in combination with that of a shovel type excavator such as a power shovel. Next, the present invention will be explained with reference to the drawings. FIG. 1 shows a power shovel 4 on which a bucket 2 is mounted, and the power shovel has an arm 6 and a boom 8. As shown in FIG.

c coincides with the outer peripheral surface of the lower wall 24 of the bucket main body 14. As shown in FIG. 3, the crushing member 16 has a substantially T-shaped planar shape, and the width of the front portion 16b protruding from the bucket main body 14 is preferably the same as that of the bucket main body 14. The front part 16b of the crushing member is located in front of the lower wall 24 of the bucket main body 14 when at rest, and a plurality of biting teeth 28 having a triangular cross section are fixed at predetermined intervals to the front edge of the front part. . Preferably, the bucket main body 14 also has a casing 30 at the inner lateral center of its upper wall 20, with a fixing bit portion 32 projecting downwardly from the front of the outer surface of the casing. In correspondence with the fixed bit part 32, the movable bit part 34 preferably projects upwardly from the front of the inner surface of the crushing member 16. The hydraulic cylinder 18 is housed in the casing 30 in a substantially horizontal state, and the rear end of the cylinder is pivoted to the bucket main body 14. The piston rod 36 of the hydraulic cylinder 18 is pivotally connected to the upper end of the vertical portion 18c of the crushing member 18 by a pin 38. At the rear of the bucket body 14, the crushing member 16 is rotatably mounted within the rear protrusion of the casing 30 by a pin 40, and the pin is positioned at a bend between the horizontal portion 16a and the vertical portion 16c of the crushing member. It is a part. Therefore, the vertical portion 16c of the crushing member is located inside the casing 30, and since the rear wall of the bucket main body 14 is open between both side walls of the casing, the vertical portion 16c is rotated to the left in FIG. It is possible to move. FIGS. 4 and 5 show a modified example of the bucket bag.

It consists of 8.

Bracket parts 52, 5 provided with a pair of pin holes 50, 50
2 is arranged vertically parallel to the bucket main body 44 and extends from above the bucket main body through the upper wall 54 to the inner center of the bucket main body.

Between the parallel bracket parts 52, 52, the upper wall 54 of the bucket main body 44 is open and a hydraulic cylinder 48 is disposed therein, the rear end of the tube being pivoted by a pin 56 to the rear upper part of the bracket part. wear it. The crushing member 46 has a substantially triangular side shape, and its width is slightly narrower than the distance between the bracket portions 52, 52 (see FIG. 5). The rear end of the crushing member 46 is pivotally connected to the lower portion of the bracket portion 52 by a pin 58, which is located approximately at the center of the inner side surface of the bucket body 44, for example. A piston rod 60 of the hydraulic cylinder 48 is pivotally connected to the upper front end of the crushing member 46 by a pin 62. Further, the lower front end portion of the crushing member 46 protrudes downward to form a movable bit portion 64.
Configure. A thick part TO having a width approximately equal to the distance between the bracket parts 52 and 52 is formed at the lateral center of the rear wall 66 and the lower wall 68 of the bucket main body 44, and the movable bit part 64 and the movable bit part 64 are formed at the front of the inner surface of the thick part. It is preferable that the fixing bit part T2 is made to protrude upward in a corresponding manner. The front edge of the lower wall 68 projects forward from the bucket main body 44, and a plurality of biting teeth T4 are fixed to the front edge at predetermined intervals. Although the power shovel 4 on which the bucket belt 2 is mounted is of a crawler type in FIG. 1, the running body may be of a known wheel type or track type to further increase mobility.

The construction machine on which this bucket cart 2 is mounted may be any shovel-type truck having an arm and a boom, such as a known power shovel or bucket shovel. When carrying out civil engineering work using the bucket 2, after moving the material to the designated work site using the power shovel 4, the material to be crushed (roughly split using a breaker or blasting) may be further broken into smaller pieces.
Alternatively, in the case of relatively small and thin concrete structures or pavement layers, it may be directly divided into small pieces. At this time, the object to be crushed is scooped up with the bucket 2, or the bucket main body 14 is placed over the object to be crushed, and then the hydraulic cylinder 18 is telescopically operated to create a gap between the crushing member 16 and the wall surface of the bucket main body 14. The object to be crushed is /'' turret 1V). In other words, when the hydraulic cylinder is extended, the crushing member rotates to the position indicated by the two-ton chain line in FIG. By giving power / J-D. When the dicing work is completed, the hydraulic cylinder is contracted to keep the crushing member stationary at the solid line position shown in Fig. 2 or 4, and the crushed material is loaded onto a truck using the bucket 2. Just put it in. If an object to be crushed that is too crowded 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 bucket 2rc is resumed. good. Also, during excavation work using the bucket 2, 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 bucket 2 does not move, the excavation work can be easily completed by covering the protrusion with the bucket main body 14 and crushing it with the crushing member 16. The bucket bucket J/MoV shown in FIG. 6 and mounted on the power shovel 76 has the same function as the bucket bucket 42 shown in FIG.

On the upper wall of the bucket main body 78, there is a parallel bracket part 8.

6) and the bucket link, respectively. Similar to the bucket 42 in FIG. 4, the crushing member 80
is pivotally connected inside the bucket main body 78, the rear end of the tube of the hydraulic cylinder 82 is pivotally connected to the rear upper part of the bucket main body 78, and the piston rod of the cylinder is pivotally connected to the front upper 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 extends forward from the lower wall of the bucket main body 78 and projects in correspondence with the movable bit portion 86. When the object to be crushed is a thin concrete structure 90 as shown in FIG.
0 and then expands and contracts the hydraulic cylinder 82 to break it into pieces with the crushing member 80. If the material to be crushed is a road pavement layer, it may be scooped out with a bucket and then divided into small pieces 9 with a 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 one construction machine, it becomes possible to load and excavate concrete structures and rocks in small pieces, making it possible to load and excavate concrete structures and rocks into small pieces, making it possible to use construction machines for each building that can be installed in inconvenient places. This avoids troubles caused by repositioning, reduces collision accidents, provides safety, and is advantageous in terms of machinery and equipment costs. In addition, with the method of the present invention, even if there are large pieces of rock or concrete that have been crushed by a machine like a breaker or by blasting, they can be broken into small pieces at the same time as the loading process, so the crusher can be separated separately. There is no need to reinstall the splitter on the deployed v or construction machine,
Extraordinary ''' chant 11! ) There is no delay in the processing of the crushed material due to the intervention of work. In addition, it is easier to reduce the size of the rocks and concrete cubes to be loaded to a constant size than with a large crusher, so crushed concrete pieces that were previously discarded can be used as basic materials for construction. It can also be reused as a substitute for balas 9 or directly disposed of at a designated treatment plant. During excavation work using the method of the present invention, even if there is a road surface pavement layer where protrusions such as concrete pieces appear, the protrusions and pavement layer can be crushed without interrupting the excavation work, and the excavation can be carried out quickly. It also has the advantage of getting the work done.
