Other than that, any other work tool that can pre-process the material to be crushed is sufficient.

  Next, the crusher 300 will be described in detail.

  FIG. 5 is a side view showing the overall structure of the crusher according to the first embodiment of the present invention, and FIG. 6 is a top view thereof. In addition, the direction corresponding to the left and right in FIG.

  5 and 6, a crusher 300 includes a lower traveling body 301 for traveling on its own, a crusher main body 302 that is mounted on the upper portion of the lower traveling body 301 and crushes an object to be crushed, and a crusher main body 302. Is constituted roughly by a discharge conveyor 303 that conveys the crushed material processed and discharged out of the machine, and a power unit (power unit) 304 that incorporates a power source (engine) of operating equipment mounted in various parts of the machine body.

  The lower traveling body 301 includes a track frame 305, driving wheels 306 and driven wheels 307 provided at the front and rear of the both ends in the width direction of the track frame 305, and a crawler belt (an endless track crawler track) wound around the driving wheels 306 and the driven wheels 307. 308 and a driving device 309 connected to the driving wheel 306.

  The crusher main body 302 includes a main body frame 310 provided on the lower traveling body 301, a housing 311 provided on the upper portion of the main body frame 310, and a hopper (receiving portion) provided on the upper portion of the housing 311 for receiving an object to be crushed. ) 315, a crusher 312 provided inside the housing 311 for crushing the object to be crushed received in the hopper 315, a drive unit 313 provided inside the housing 311 for driving the crusher 312, and a lower part of the housing 311 And a chute 314 for discharging the crushed material crushed by the crushing device 312 onto the discharge conveyor 303.

  The hopper 315 has a shape that expands from below to above, and has an upper opening 316 and a lower opening 317. The hopper 315 accepts crushed objects (coarse garbage, plastic waste, old tires, waste wood, household appliances, etc.) that are input through the upper opening 316 by an input heavy machine (hydraulic excavator, conveyor, screen, etc.). . The lower opening 317 is an opening that opens toward the inside of the housing 311 with a predetermined dimension (L1 × L2) as shown in FIG. 6, and is configured so that the crushing device 312 inside the housing 311 can face through the opening. ing. The object to be crushed received by the hopper 315 is fed into the crushing device 312 through the lower opening 317.

  The crushing device 312 is generally configured from two rolls arranged in parallel along the longitudinal direction of the machine body, and a plurality of cutters (cutting teeth) 318 and spacers 319 arranged alternately along the axial direction. . These two rolls are configured such that the cutter 318 of one roll faces the spacer 319 of the other roll, and is rotated by the rotational power given by the drive unit 312. The two rolls configured in this manner rotate in different directions so that each object collaborates and bites the object to be crushed downward (in the direction of the discharge conveyor 303), and shearing force is used to crush the object to be crushed. Crush things. Thus, the crushed material crushed by the crushing device 312 is discharged onto the discharge conveyor 303 via the chute 314.

  The discharge conveyor 303 includes a conveyor frame 320, driving wheels 321 and driven wheels 322 provided at both ends in the longitudinal direction of the conveyor frame 320, and a conveyor belt 323 wound around the driving wheels 321 and driven wheels 322.

  The conveyor frame 320 is suspended and supported by a support member 324 attached to the main body frame 310 and a support member 325 attached to the power unit 304. One end of the rotation shaft of the drive wheel 320 is connected to the drive device 326, and the conveying belt 323 is driven by the rotational power provided by the drive device 326. The crushed material discharged from the chute 314 is transported on the transport belt 323 and then dropped from the end of the belt 323 to be discharged out of the crusher 300.

  Here, the necessity of the pre-processing (rough crushing including cutting) performed prior to the crushing process by the crusher 300 will be described. A crusher has a general limit on the size of an object to be crushed. For example, the maximum diameter (referred to as the maximum processing diameter) that can be crushed by the crusher 300 in the present embodiment is the dimensions of the lower opening 317 (the machine body longitudinal direction (L1) and the machine body width shown in FIG. 6). Direction (L2)), dimensions of the rollers of the crushing device 312 and the cutters 318 and spacers 319 disposed on the rollers. Therefore, if the diameter of the object to be crushed received by the hopper 315 is larger than the maximum processing diameter, the object stays in the hopper 315 and is not guided to the crushing device 312 via the lower opening 317 or is crushed even if guided. The rotating shaft may idle without being bitten by the device 312 and the object to be crushed may not be crushed. For this reason, in order to crush the object to be crushed having a size exceeding the maximum processing diameter, cutting, rough crushing, etc. are carried out before the hopper 315 is put into place so as to make it smaller than the maximum processing diameter (pretreatment). There is a need. Even when the size of the object to be crushed is equal to or less than the maximum processing diameter, it may be preferable to pre-process the object to be crushed in consideration of the load of the crusher and the crushing efficiency. As described above, the pretreatment is necessary from the viewpoint of improving the relationship with the maximum processing diameter of the crusher and crushing treatment efficiency.

  Next, returning to FIG. 1 and FIG. 2, the entire configuration of the crushing processing system of the present embodiment using the hydraulic excavator 200 and the crusher 300 configured as described above will be described in detail.

  Here, when the excavator 200 tries to grasp the object to be grasped on the ground with the work tool 214A using only the front work device 204A without moving and turning, the work tool is moved from the position of the turning axis O. The distance to the position where 214A can grip the object is defined as the working radius R of the excavator 200. When the work radius R is defined in this way, the work area S in which the work object 214A can be gripped by using the work tool 214A without moving the excavator 200 is indicated by a two-dot chain line in FIG. The radius is indicated inside a circle whose center corresponds to the turning axis O of the upper turning body 202 and whose radius corresponds to the working radius R. Here, the gripping work has been described as an example. However, if the work tool is replaced, other work of the gripping work is possible, and if it is within this region S, the work according to the work tool is performed without moving. Needless to say, you can.

  The to-be-crushed object 1 is a to-be-crushed object that needs to be pre-treated before being put into the hopper 315 of the crusher 300 because of the maximum processing diameter of the crushable object to be crushed by the crusher 300. In the present embodiment, the object to be crushed 1 is a long log material.

  The crushed object stock yard 100 is a place where the crushed objects 1 are accumulated in advance. In the stock yard 100, the crushed object 1 is accumulated so that at least a part of the object 1 enters the region S so that the excavator 200 can be gripped by the front working device 204A. That is, it is sufficient that the excavator 200 can grip the object 1 without moving, and the stock yard 100 and the entire object 1 need not be included in the region S. However, from the viewpoint of facilitating gripping work by the hydraulic excavator 200, it is preferable that the objects 1 to be crushed in the stock yard 100 are arranged so that all parts of the crushed wood 1 are within the region S. . If it arrange | positions in this way, since the hydraulic shovel 200 can hold | grip the to-be-crushed object 1 easily, a crushing processing system can be operated efficiently. In FIG. 2, the object to be crushed 1 is arranged such that the longitudinal direction thereof is along the radial direction of the region S. However, the arrangement direction is not particularly limited to this, and for example, in the tangential direction of the region S Of course, it may be arranged along. Further, the number of the stock yards 100 arranged is not particularly limited. Therefore, as shown in FIG. 2, the arrangement is not limited to the arrangement in which the stock yard 100 is arranged at three places so as to surround the excavator 200 in the region R, and other arrangements and arrangement numbers may be employed.

  The to-be-crushed object 2 (refer FIG. 1) is the to-be-crushed object which the hydraulic excavator 200 cut | disconnected with the work tool 214B, and pre-processed, holding the to-be-crushed object 1 with the work tool 214A.

  The crusher 300 is arranged so that at least a part of the upper opening 316 is included in the region S. This is because the excavator 200 can pre-process the object to be crushed 1 gripped by the front work apparatus 204A on the hopper 315 with the front work apparatus 204B, and can directly input the pre-processed object 2 to the hopper 315. It is for doing so. The arrangement of the crusher 300 is preferably such that the entire upper opening 316 is located within the region S. When arranged in this way, the object to be crushed 2 can be reliably guided to the crushing device 312 and the cutting waste of the object to be crushed 1 generated during the pre-treatment is prevented from being scattered outside the hopper 315. This can reduce the labor of cleaning. In addition, as with the arrangement of the object 1 to be crushed, the work by the hydraulic excavator 200 is facilitated, and the crushing efficiency is improved.

  The chip yard 400 is a place where the crushed material 3 crushed by the crusher 300 is accumulated. In the chip yard 400, the crushed material 3 falls and accumulates from the end of the discharge conveyor 303 of the crusher 300, so that a pile of the crushed material 3 is formed below the end. In addition, the crushed material 3 in this Embodiment is a wood chip.

  Here, when the arrangement of the components in the present embodiment is summarized, the excavator 200 picks up and holds the object 1 to be crushed in the stock yard 100 on the spot by the front working device 204A. The crushed object 1 is roughly crushed by the front working device 204B on the hopper 315 of the crusher 300, and the roughly crushed object 2 can be directly put into the hopper 315 of the crusher 300 so that the hopper 315 of the crusher 300 can be directly fed. And the to-be-crushed material accumulation field 400 is arrange | positioned in the working radius R of the hydraulic shovel 200. FIG.

  Next, the crushing process of the material to be crushed in the crushing system of the present embodiment configured as described above will be described.

  First, using the double-armed hydraulic excavator 200, the object to be crushed 1 accumulated in the object to be crushed stock yard 100 is grasped by the front working device 204A. Then, the upper turning body 202 is turned while holding the state of gripping the object 1 to be crushed by the work tool 214A, and the end of the gripped object 1 on the work tool 214B side is the center of the upper opening 316 of the crusher 300. Stop turning at a location near the top. Here, the object 1 to be crushed held by the front work device 204A is cut by the front work device 204B, and the object 2 to be crushed has a size suitable for the crusher 300 to crush. Thus, the object 2 to be crushed separated from the object 1 to be crushed by the front working device 204B is dropped by gravity at the same time as being cut, and is received by a hopper 315 located below the object. As described above, according to the present embodiment, the excavator 200 can grab and crush the object 1 without moving, and the crushable object 1 can be reduced to a size that can be crushed. While cutting (pretreatment), it can be directly put into the hopper 315 of the crusher 300.

  Subsequently, the object 2 to be crushed received in the hopper 315 as described above is sent to the crushing device 312 through the lower opening 317 and is crushed by the crushing device 312 to become the crushed material 3. The crushed material 3 obtained in this way is discharged from the inside of the casing 311 onto the discharge conveyor 303 via the chute 314. The crushed material 3 discharged onto the discharge conveyor 303 is transferred to the front of the machine body by the transfer belt 323 and discharged outside the machine at the end of the discharge conveyor 303. Since the discharged crushed material 3 falls due to gravity and accumulates at a position below the end of the discharge conveyor 303, a pile of the crushed material 3 is formed in the chip yard 400.

  Next, the operation and effect of the present embodiment will be described.

  First, in order to facilitate understanding of the present invention, a comparative example of the present embodiment will be described. In this comparative example, a hydraulic excavator having only one front work device is used as a heavy machine for charging the material to be crushed into the crusher.

  FIG. 7 is a side view showing the overall arrangement of a crushing processing system which is a comparative example of the present embodiment.

  The crushing processing system shown in FIG. 7 includes a crushed object stock yard 100 in which the crushed objects 1 are accumulated, a preprocessing work space 500 for cutting the crushed objects 1 and performing preprocessing, and preprocessing. A processed crushed object stock yard 600 for accumulating the crushed objects 2, a work machine (hydraulic excavator) 700 that has one front work device 704 and that feeds the crushed objects 2 into the crusher 300; A crusher 300 that crushes the object 2 to be crushed by the excavator 700 and a chip yard 400 in which the crushed material 3 is accumulated are mainly provided. Here, like the working radius R of the excavator 200 in the present embodiment, the working radius of the excavator 700 in this comparative example is Rc.

  The preprocessing work space 500 is a space in which the worker 4 manually cuts the object 1 by using a cutting tool (for example, a chainsaw) to perform preprocessing. The excavator 700 is disposed outside the working radius Rc. In the processed crushed object stock yard 600, the crushed objects 2 that have been pre-processed in the work space 500 are accumulated, and are arranged in the work radius Rc in consideration of the improvement of the charging efficiency by the hydraulic excavator 700. Unlike the double-armed hydraulic excavator 200 of the present embodiment, the hydraulic excavator 700 has only one front work device 704 with a grapple 714 attached to the tip.

  In this comparative example, first, the material 1 to be crushed is transported from the stock material yard 100 to the preprocessing work space 500. Therefore, the worker 4 cuts the object 1 to be crushed and pre-processes the object 2. The object 2 to be crushed obtained in the work space 500 is transported to the processed object to be crushed stock yard 600 where the heavy machinery is collected so that it can be easily picked up. The objects to be crushed 2 accumulated in the stock yard 600 in this manner are gripped by the hydraulic excavator 700 and then put into the hopper 315 of the crusher 300. The inputted crushed object 2 is crushed by the crusher 300 and accumulated in the chip yard 400.

  Only one front working device is attached to the hydraulic excavator 700 in the comparative example configured as described above, and the pretreatment of the object to be crushed 1 cannot be performed alone. Therefore, in addition to the crushed object stock yard 100, a work space 500 for pre-processing the crushed object 1 and a stock yard 600 for collecting the pre-processed crushed objects 2 are required. In addition, due to safety issues of the worker 4 working in the work space 500, it is also necessary to arrange the work space 500 at a location sufficiently away from the excavator 700.

  Thus, when a pre-processing process is required, the space which a crushing processing system occupies expands as a crushing processing process increases. This causes a trouble of transporting and accumulating the objects to be crushed by heavy machinery or manpower when moving from one processing step to the next processing step, which also causes a reduction in work efficiency. In addition, even if we try to reduce the area occupied by the system in order to improve work efficiency, there are limits to making the system compact when considering the safety of workers as described above, improving work efficiency. There is a limit to making it happen. Further, in the vicinity of the work space 500, there is a considerable amount of time and effort for cleaning such as dust and dust generated with the pretreatment work.

  In contrast to such a comparative example, the present embodiment has a system configuration in which a double-armed hydraulic excavator 200 having a gripping tool 214A on one front working device 204A and a rough crushing tool 214B on the other front working device 204B is configured. The crushing processing system is configured by incorporating both the hopper 315 and the stock yard 100 within the working radius R (in the region S) of the excavator 200. With this configuration, the excavator 200 according to the present embodiment grasps and crushes the object to be crushed 1 with one work device 204A, and cuts the object to be crushed 1 with the other work device 204B. The pretreatment can be performed, and the preliminarily processed object 2 to be crushed can be directly put into the hopper 315 of the crusher 300.

  In the present embodiment, as described above, the hydraulic excavator 200 can perform a plurality of processing steps including pre-processing on the object to be crushed 1 and charging into the crusher 300. Thereby, since the crushing process can be simplified, the time required for the crushing process is shortened, and the working efficiency is dramatically improved. In addition, since it is no longer necessary to pre-process the objects to be crushed, there is no need for a pre-processing work space or a space for collecting pre-processed objects to be crushed. A crushing processing system can be constructed only by providing 100. As a result, the occupation area of the system can be reduced, and the working efficiency is further improved. Furthermore, since only the operator of the hydraulic excavator 200 can perform the pre-processing on the object 1 to be crushed and the charging into the crusher 300, the number of workers required for the crushing processing system can be reduced. Further, in the present embodiment, the object 1 to be crushed can be cut on the hopper 315 and pre-processed, so that the cutting waste generated when the object 1 is cut can also be crushed together. Thus, it is possible to reduce the trouble of cleaning the waste and dust generated in the pretreatment.

  In addition, in the above description, although the system which crushes log timber as a to-be-crushed object has been demonstrated, of course, a to-be-crushed object is not restricted only to log timber. For example, it is needless to say that the present invention is applicable as long as the crusher 300 having a shearing crusher can process, such as coarse garbage, plastic waste, old tires, waste wood, and home appliances.

  Subsequently, in the following, a modification of the first embodiment will be described.

  8 to 10 are side views showing the overall arrangement of a modification of the first embodiment. The first modification shown in FIG. 8 is for the tatami mat 6, the second modification shown in FIG. 9 is for the old tire 9, and the third modification shown in FIG. .

  In FIG. 8, the tatami 6 is pre-processed by the hydraulic excavator 200 and directly input to the crusher 300 as the tatami 7, crushed by the crusher 300, and accumulated as the crushed material 8 in the crushed material accumulation site 400. In FIG. 9, the old tire 9 is pre-processed by the hydraulic excavator 200 and directly input to the crusher 300 as the old tire 10, is crushed by the crusher 300, and is accumulated as the crushed material 11 in the crushed material accumulation site 400. . In FIG. 10, the branch and leaf material 12 is pre-processed by the excavator 200 and directly fed into the crusher 300 as the branch and leaf material 13, and is crushed by the crusher 300 and accumulated as the crushed material 14 in the crushed material accumulation site 400. Is done.

  As described above, the same effects as those of the first embodiment can be obtained even when the tatami mat 6, the old tire 9, the branch leaf material 12, and the like are targeted for crushing in addition to the log wood. In addition, as described above, the work tools 214A and 214B of the excavator 200 can have the main body portions 221A and B pivotable with respect to the mounting portions 219A and B. Therefore, by appropriately turning these, even a non-expert operator can easily perform pre-processing on an object to be crushed having a complicated shape. For example, the annular-shaped old tire 9 shown in FIG. 9 can be flexibly adapted to the shape, and the shape of the branch and leaf material 12 can be changed even when pre-processing the branch and leaf material 12 shown in FIG. The object can be cut as appropriate. In addition, the turning function of the work tools 214A and 214B has a further effect when a long object to be crushed is pre-processed. That is, if this turning function is used, for example, when a long log is gripped horizontally and cut with a coarse crushing tool in order from one side, the wood can no longer be cut from that direction. The cutting operation can be continued by reversing the cutting side by turning the gripping tool holding the log material 180 degrees. Therefore, if the above-mentioned turning function is used, the pretreatment can be continuously performed without placing the object to be crushed on the ground and re-gripping it.

  Moreover, since the hydraulic excavator 200 and the crusher 300 which comprise the crushing processing system of this Embodiment have the lower traveling bodies 201 and 301, respectively, and can be self-propelled, the installation place of the said system, each machine, and space Arrangement etc. can be flexibly changed according to the circumstances of the site. Moreover, since the crushing processing system itself can go to the place where the crushing object (raw material) is, it is possible to reduce the trouble of transporting the crushing object.

  On the other hand, as described above, the excavator 200 and the crusher 300 in the present embodiment do not need to move basically during the crushing operation once it is arranged at a predetermined position. Therefore, in a use destination (for example, use in a garbage disposal facility) that does not require a change in the installation location of the crushing processing system, the lower traveling bodies 201 and 301 can be removed to form a stationary system. Hereinafter, such a configuration will be described as a second embodiment of the present invention.

  FIG. 11 is a side view showing the overall arrangement of the second embodiment of the present invention. This embodiment is different from the first embodiment in that the excavator and the crusher are stationary.

  The crushing processing system shown in FIG. 11 mainly includes a stationary crushing machine 800, a material stock yard 100 to be crushed, and a chip yard 400. The stationary crusher 800 includes a hydraulic excavator 200D and a crusher 300D mounted on an installation table 801. The excavator 200D has substantially the same configuration as that obtained by removing the lower traveling body 201 from the excavator 200 used in the first embodiment. Like the excavator 200D, the crusher 300D has substantially the same configuration as that obtained by removing the lower traveling body 301 from the crusher 300 used in the first embodiment. In addition, the hydraulic excavator 200D and the crusher 300D are driven by pressure oil supplied by an engine-type hydraulic pump (not shown) mounted on each machine body, as in the first embodiment. Thus, if a crushing processing system is comprised, the crushing processing system which concerns on this invention can be implemented as a stationary type.

  Further, since the hydraulic excavator 200D and the crusher 300D are of a stationary type, it is easy to supply electricity, so that an electric hydraulic pump is used as pressure oil supply means instead of the engine hydraulic pump. You may do it. If the electric hydraulic pump is used, it is not necessary to consider the treatment of the exhaust gas generated by driving the engine. Therefore, the crushing treatment system can be constructed indoors without installing a special ventilation facility.

  By the way, in the description of each of the above-described embodiments, the description has been given of the one in which the object to be crushed that has been pre-processed by the hydraulic excavators 200 and 200D is directly input to the crushers 300 and 300D. It may be configured such that an object to be crushed is put into a hopper such as a belt conveyor) or a sorter (for example, a self-propelled screen), conveyed, sorted, and then crushed by the crusher 300. Hereinafter, an example thereof will be described as a third embodiment of the present invention.

  FIG. 12 is a side view showing the overall arrangement of the third embodiment of the present invention. The present embodiment is different from the first embodiment in that the object to be crushed that has been pre-processed by the hydraulic excavator 200 is directly fed into the hopper of the self-propelled belt conveyor 900, and the crusher is passed through the belt conveyor 900. This is the point that the object to be crushed is put into 300.

  The crushing processing system shown in FIG. 12 includes a self-propelled belt conveyor (conveying machine) 900 in addition to the components of the first embodiment. The self-propelled belt conveyor 900 includes a lower traveling body 901, an upper vehicle body 902 attached to an upper portion of the lower traveling body 901, a conveyor device 903 that is attached to an upper portion of the upper vehicle body 902 and conveys a loaded object. A hopper 904 that is provided above one end of the conveyor device 903 and receives the pre-processed object 2 to be crushed. The upper opening of the hopper 904 is disposed inside a region S indicating that it is within the working radius R of the excavator 200. Further, the other end of the conveyor device 903 is disposed on the opening of the hopper 315 of the crusher 300, and the object to be crushed 2 that is directly input to the hopper 904 while being pre-processed by the excavator 200 passes through the conveyor device 903. To the hopper 315. Even in the crushing processing system configured as described above, the object 2 to be crushed by the hydraulic excavator 200 can be indirectly put into the hopper 315 of the crusher 300 and crushed, so that efficient crushing processing is performed. be able to.

  In addition, in the above, although the case where a system was comprised using the crusher which has a shearing-type crushing apparatus was demonstrated, the crusher which can be utilized is not restricted only to this kind. It is not limited to crushing methods of crushers (for example, a jaw crusher having a compression crushing device or an impact crusher that crushes by impact action). However, it can be applied as long as it can be directly put into the hopper of the crusher. In such a case, the rough crushing tool of the hydraulic excavator is changed in accordance with the properties of the object to be crushed (for example, when crushing a concrete lump, the rough crushing tool is a crusher or a breaker). ) Needless to say.
