[Field of the Invention]
  This invention breaks up lump bodies such as concrete, asphalt, rocks, industrial waste, etc. generated by destruction or collapse of buildings, structures, etc., or excavation of roads, etc. into desired size granules, The present invention relates to a lump crushing plant vehicle in which a crushing plant that enables reuse of objects is mounted on a vehicle such as a truck traveling on a general road.
[0002]
[Prior art]
  Recently, particularly in urban areas, work such as demolition and rebuilding of mid-to-high-rise housing, buildings, structures, etc. has been carried out in order to redevelop areas where many buildings have already been constructed, such as residential areas and urban areas. Sometimes. It is necessary to treat the lump such as concrete and asphalt generated at that time, but the dumping process, which is a common treatment method, has gradually become difficult to secure a place where the lump is legally dumped. As a result, it could no longer be adopted easily. In view of this, a method of reducing the amount of dumping is performed by effectively using resources that are reused, that is, recycled, such as waste materials such as buildings and structures, and aggregates such as concrete and asphalt. In particular, lump such as concrete and asphalt is crushed by a crusher, and the crushed material is reused as recycled materials such as road materials, building materials, foundation materials such as structures, and backfill materials after excavation. Came to be done.
[0003]
  It is possible to crush lump such as concrete, asphalt, waste materials, etc. at the site where the lump is generated, and transport the crushed particles obtained on site to a predetermined place for use as recycled products. , It is preferable for environmental protection and effective use of resources. It is no longer necessary to find landfills and dumping places for these lumps and transport them for a long distance with a vehicle or the like, and the environment will not be destroyed due to the dumping of the lumps. In addition, if the crushed granular material is used as a recycled product, the amount of gravel, which is a limited resource, can be reduced.
[0004]
  Conventionally, most of the crushing plants that crush agglomerates such as concrete, asphalt, waste materials, etc. are installed type crushing plants that are installed and used in the treatment plant. At present, the machine is transported to a predetermined processing site by loading a machine, a conveyor, etc., and the crushing machine is lowered from the trailer at the lump processing site, and the lump is carried to the processing site. Such a crushing plant basically includes a crusher that crushes a lump such as concrete, asphalt, and waste material, a sorting mechanism that sorts the crushed crushed material, and a driving device such as a generator. In addition, mobile crushing plant vehicles that can move in the treatment plant have been developed as crushing plants, but these mobile crushing plant vehicles are moved only at the treatment plant and are legally restricted to general roads. I couldn't run.
[0005]
  By the way, the present applicant has already proposed a crushing plant vehicle in which a crushing plant is installed on a trailer capable of traveling on the road and conforms to the safety standards of the Road Transport Vehicle Law (see, for example, JP-A-6-254429). ). The crushing plant car consists of a tractor and trailer for running on the road equipped with an engine. The crushing machine crushes waste materials such as buildings, structures, etc., and lumps such as concrete and asphalt, and crushes crushed materials. A crushing plant consisting of vibration sieves, return conveyors, conveyors, and driving devices such as generators that drive these devices is installed on trailers so that it can conform to safety standards, and also in urban and urban areas. It is possible to reduce the generation of noise, vibration, etc. as much as possible even when the is operated.
[0006]
[Problems to be solved by the invention]
  However, the above-mentioned crushing plant vehicle is a vehicle that has cleared the restrictions on the width and height of the vehicle, conforms to safety standards, and is capable of traveling on the road, including a tractor and a trailer to be pulled by the tractor. It is a large vehicle consisting of Therefore, there are restrictions on the roads on which the crushing plant vehicles can travel, and if the roads that access the crushing work place are narrow roads in urban areas, the crushing plant car must go to the crushing work place. May not be possible. Further, since the crushing plant vehicle is installed on a vehicle body frame composed of a chassis and a reinforcing frame, the generation of noise from the vehicle body frame during operation of the crushing plant is suppressed, and the vibration generated in the equipment is directly applied. In order to avoid transmission to the rear wheel, it was necessary to install an air cushion and a leaf spring to attach the chassis to the rear wheel. In the trailer, the structure of the body frame itself needs to be a special structure that incorporates a reinforcing frame, an air cushion, and a leaf spring.
[0007]
  Moreover, in the conventional crushing plant vehicle, the following related structures are adopted in the hopper provided in the upper part of the crusher in order to put the material to be crushed into the crusher. The ground clearance at the upper edge of the hopper is set to a height that meets the safety standards when the vehicle is traveling on the road. On the other hand, during the operation of the crushing plant, the crushed material that has been crushed by the crusher and then transferred to the vibrating sieve by the conveyor is oversized by the vibrating sieve and needs to be re-crushed. In order for the return conveyor to enter the hopper again, the return conveyor must be brought up above the top edge of the hopper, while when traveling on the road, the upper part of the return conveyor must be moved to meet the safety standards. It is necessary to place it below the upper edge. For this reason, it is necessary to provide the return conveyor with a tilt angle changing mechanism in order to change the height on the hopper side of the crusher to meet the safety standards. Thus, the upper end position of the return conveyor has to be changed up and down when the vehicle is running and when the crushing plant is in operation, and the change operation is troublesome.
[0008]
  In the conventional crushing plant, the fragments of the crushing material generated in the crusher are moved to the outside of the crusher by suspending the chains so that they are closely arranged in a line at the inlet from the hopper to the crusher. Although it was prevented from flying away, it should completely prevent small pieces from flying away, and also prevent the dust generated when the material to be crushed from being crushed by the crusher from being scattered outside. There was an inconvenience that it was not possible. Dust and particulates that scatter to the outside not only adversely affect the surrounding environment, but can also cause health problems for workers in the crushing plant.
[0009]
[Means for Solving the Problems]
  This invention,massHopper for charging the material, crusher for crushing the lump,in frontA vibratory feeder for supplying the lump that has been put into the hopper to the crusher, a vibrating sieve for sorting out the granulated material obtained by crushing the lump with the crusher, and the granulating material from the crusher to the vibrating sieve Conveyor for transporting to the slab, a granular conveyor of a size larger than a predetermined size selected by the vibration sieve machine, a return conveyor for forwarding the granular material from the vibration sieve machine to the crusher again, and a size less than a predetermined size selected by the vibration sieve machine Granular material discharging means for discharging the granular material to the outside,as well asDrive device for driving these devicesThe vibration feeder is supported by a vibration absorbing support on a pedestal on a vehicle body frame, and the granular material having a predetermined size or more from the vibration sieve is placed on the vibration feeder by the return conveyor. The vibration generating means of the vibration feeder is configured such that a pair of motors that generate an unbalanced force accompanying the rotation of the rotating shaft are mounted on the lower surface of the vibration feeder symmetrically with respect to the center line of the vibration supply direction. The rotation shaft of the vibration generating means is composed of vibration motors that rotate in reverse directions so that the phases of the unbalanced forces are symmetrical with respect to the center line in the vibration supply direction.The present invention relates to a lump crushing plant vehicle equipped with a crushing plant in a vehicle.
0010]
  The vibration-absorbing support body is composed of a rod-shaped rubber body and a spring embedded spirally in the longitudinal direction of the rod-shaped rubber body, and is provided with locking holes at both ends of the rod-shaped rubber body. . Therefore, the vibration generating means can be easily disposed between the device and the vehicle body frame or the gantry and can be firmly fixed by engaging the projection provided on the device and the vehicle body frame or the gantry in the locking hole.
0011]
  In addition, an openable and closable dustproof cover for preventing dust and particulates from being scattered when the lump is crushed is provided in the region of the inlet of the vibratory feeder to the crusher.
0012]
  The crusher and the vibration sieve are installed on the vehicle body frame via a vibration absorbing support. Therefore, the crushing plant as a whole can be configured to greatly reduce vibration and noise.
0013]
  The lump crushing plant vehicle further includes a work scaffold pivotally attached to a pedestal around the hopper installed on the vibration feeder provided adjacent to the crusher. When not in use, a handrail is stored in an upright state on the pedestal that supports the hopper, and is pivoted with respect to the pedestal that supports the hopper when in use and is extended in a substantially horizontal state and pivotally attached to the work scaffold. It can be erected.

  The vibration generating means of the vibration feeder includes a pair of motors that generate an unbalanced force associated with the rotation of the rotation shaft attached to the lower surface of the vibration feeder symmetrically with respect to a vibration supply direction center line. Is composed of vibration motors that rotate in opposite directions so that the phases of the unbalanced forces are symmetrical with respect to the center line of the vibration supply direction.SoIn the vibration feeder, the lump can be smoothly transferred. In the vibration motor, the lump can be supplied most efficiently, and even if the phase of the unbalance force is shifted,oneEven if the rotation directions of the motors for vibration generation are the same, the efficiency of supplying the lump is deteriorated. Examples of means for generating an unbalanced force in association with the rotation of the rotating shaft include those having an eccentric body attached to the rotating shaft and those having a magnet that attracts and repels a fixed magnet attached to the rotating shaft. .
0015]
  Further, in the present invention, since a vibration feeder that is not a type having a return travel path that travels in the opposite direction to the transport travel path, such as a belt conveyor, is used as the transport means, the dimension in the height direction is short, and the hopper, The overall height of the vibratory feeder and the crusher does not increase, and the supply of lumps from the hopper to the crusher can be averaged to an appropriate supply amount so as not to be supplied in large quantities at once. The vibratory feeder is disposed so as to be slightly inclined downward from the position corresponding to the outlet position of the hopper toward the inlet of the crusher. In order to drive the vibration feeder, it is only necessary to attach a vibration motor to the bottom surface of the feeder. The vibration feeder is supported on the vehicle body frame by a vibration absorbing support body in which a spring is embedded in a rod-shaped rubber body. Since these vibration generating means and vibration absorbing support provided on the bottom side of the vibration feeder can be arranged with respect to the vehicle body frame at a position where they do not interfere with the crusher, there is no concern of increasing the overall height of the device. Absent. The vibration generated by the vibration feeder during operation of the crushing plant can be buffered by the vibration absorbing support for the body frame, so that the generation of vibration and noise can be greatly reduced when supplying the lump.
0016]
  According to the present invention, the crushed material of a predetermined size or more that is fed by the return conveyor is not returned to the hopper, but is returned to the vibrating feeder provided between the hopper and the crusher. Therefore, the height dimension between the transport path and the forward path at the return conveyor outlet is well within the height dimension between the inlet and outlet of the hopper. The return conveyor can be installed without leaving the outlet beyond the height of the hopper, and there is no concern about increasing the overall height of the device. In addition, since there is no structural interference between the lump loading hopper and the return conveyor, the hopper structure is simplified, and the inclination angle of the return conveyor is changed to reduce the height of the top of the return conveyor. There is no need to provide a conveyor inclination changing device, and as a result, there is no need to change the conveyor inclination angle at the start and end of the operation of the crushing plant. The installation height of the hopper, which is the height of the vehicle, can be configured to meet the safety standards, so that it is possible to travel on the road with the crushing plant installed in the body frame.
0017]
  Therefore, this lump crushing plant car is transported to the site where crushed materials such as concrete and asphalt are generated with the crushing plant installed, and the crushing material is immediately crushed with the crushing plant installed on the body frame. Therefore, the crushing process can be performed efficiently without taking time for the work setup. The return conveyor outlet of the return conveyor once faces the return hopper, and the crushed material having a large size is joined from the return hopper to the vibration feeder through the return feeder. The return feeder faces the exit on the conveyance path of the vibration feeder so as to be orthogonal to the conveyance direction of the return conveyor. The return feeder receives vibration from the vibration feeder as an integral structure with the vibration feeder.
0018]
  According to the present invention, the cover that can be opened and closed is provided across the carry-out port of the vibration feeder and the input port to the crusher. By providing such a cover, it is possible to prevent not only the fragments of the object to be crushed generated by the crusher but also the dust generated when the object to be crushed is scattered to the outside. In addition, since it can be opened and closed, there is no problem in operations such as inspection and repair of the vibration feeder and crusher. Moreover, a sprinkling means may be provided between the exit of the vibratory feeder and the inlet to the crusher to suppress the generation of dust.
0019]
  Since the lump crushing plant vehicle according to the present invention uses a normal truck, only a normal buffer is provided between the body frame and the wheel of the truck. When the crusher is mounted directly on the truck body frame, the vibrations generated by the crusher may damage the wheels and increase the noise throughout the truck body. According to this lump crushing plant vehicle, the vibration source such as the crusher or the vibration sieve is attached to the vehicle body frame or mount via a vibration absorbing support such as a rubber sheet. Is not transmitted directly to the vehicle body frame, and vibration and noise generated by the crushing plant during crushing work can be reduced.

  In this lump crushing plant vehicle, plant equipment such as a crusher 6 and a vibration sieve 7 are operated on the vehicle body frame 4 while the rear wheel 3 is in contact with the ground. A rear column 19 such as a jack that can be expanded and contracted by hydraulic pressure, a link, a screw or the like is provided at the rear portion of the body frame 4 of the truck in order to support a force such as impact force or vibration generated by the crusher 6 beyond a predetermined level. It has been. The rear support column 19 is almost grounded when the crusher 6 is operated, or is extended to the grounded state with a floor plate or the like. When an excessive load is applied to the truck by the crusher 6, the rear frame 19 supports the vehicle body frame 4, The buffer means can be protected. In this lump crushing plant vehicle, the vibration sources such as the crusher 6, the vibration feeder 21, the lower vibration feeder 11, the vibration sieve 7 and the like are connected to the vehicle body frame 4, the frame, Supported by a gantry.
0025]
  The vibration absorbing support 15 will be described later in connection with the detailed description of the crusher 6 and the vibration sieve 7. For example, in the crusher 16, the impact force generated by crushing crushed materials such as concrete and asphalt, A part of force such as vibration can be buffered and absorbed, and generation of noise can be prevented. As shown in FIGS. 8 and 9, the vibration absorbing support 15 includes a solid rod-shaped rubber body 20 and a spring 30 embedded spirally in the longitudinal direction of the rod-shaped rubber body 20. Locking holes 77 are provided at both ends of 20. The vibration-absorbing support 15 has a structure in which the center is aligned in the longitudinal direction so that the coil central axis of the spring 30 coincides with the central axis of the rod-shaped rubber body 20.

The peripheral structure related to the scaffolding such as the tilt plate 127 around the vehicle body frame 4 will be described later.
0027]
  Next, the details of the vibration feeder 21 that conveys the lump that has been put into the hopper 16 to the crusher 6 will be described with reference to FIGS. 10 to 13.A frame 33 that also serves as a hopper mount is provided on the vehicle body frame 4 so as to surround the generator 8 installed at the rearmost part of the vehicle. The hopper 16 is supported by pillars 106 fixed at four corners with respect to the frame 33 constituting the gantry, and is located in the space above the generator 8. A cover 22 is rotatably supported by a hinge on an upper edge portion of the hopper 16 on the vehicle front side. When the vehicle is traveling, the cover 22 is closed so as to cover the upper part of the hopper 16, and the safety standard relating to the vehicle height is met. When the crushing plant is driven, the cover 22 is brought into the most open state located on the extended line of the slope of the hopper 16. In this state, for example, when a lump is loaded with a power shovel, the cover 22 exhibits the same effect as widening the lump area for the hopper 16 and the lump is sprinkled on the crusher 6. Acts as a protective device to prevent. The hopper 16 is supported by the vehicle body frame 4 via the frame 33 and the support column 106. However, when a lump adheres to the hopper 16 in the rain or the like and the supply to the crusher 6 is hindered, the hopper 16 is supported. 16 may be vibrated. In this case, the support column 106 is supported on the frame 33 of the gantry via a vibration absorbing support 15 to be described later so as to absorb vibration.
0028]
  The vibration feeder 21 extends in a slight downward gradient from immediately below the outlet 23 of the hopper 16 to the vicinity of the inlet 24 of the crusher 6. A wall surrounds the periphery of the vibration feeder 21 except for the inlet 24 side of the crusher 6, thereby preventing a lump from falling to the outside of the vibration feeder 21. As shown in FIG. 13, a pair of vibration motors (Eurus motors) 25 and 26 are attached to the bottom surface of the vibration feeder 21 by bolts 28 via brackets 27 at positions symmetrical to the center line in the supply direction. It is attached. The vibration motors 25 and 26 are of a type that generates vibration by the rotation of the eccentric bodies, and the eccentric bodies rotate in opposite directions so that their phases are symmetrical with respect to the center line of the vibration supply direction. In other words, the eccentric body attached to each motor shaft is selected as the one closest to the line segment connecting both the motors 25 and 26 for crossing at the same time and rotating in the direction that encourages the supply of the vibration feeder 21. . As for the transfer of the lump on the vibration feeder 21 by the vibration motors 25 and 26, the supply efficiency is best when the relationship between the rotation direction and the phase is satisfied.
0029]
  The vibration feeder 21 is supported on the frame 33 on the vehicle body side via the vibration absorbing support 15 at a plurality of locations. Support metal fittings 29 and 29 are provided on the side of the vibration feeder 21, and rod-shaped vibration absorption support bodies 15 are interposed between the support metal fittings 29 and the vehicle body side frame 33. ing. Each vibration absorbing support 15 buffers and absorbs vibrations caused by both vibration motors 25 and 26 so as not to transmit strong vibrations to the frame 33 and suppresses the generation of noise.
0030]
  Next, the crusher and the lower vibration feeder will be described with reference to FIGS.A dustproof cover 34 covers between the carry-out port 31 of the vibration feeder 21 and the input port 24 of the crusher 6. The dust cover 34 has a shape of a quarter of a cylindrical body as a whole. The dust cover 34 can be rotated around an axis 35 extending in the lateral direction of the vehicle body with respect to the outer frame of the crusher 6, and the rotation axis 35 coincides with the generatrix of the cylindrical body. Since the edge of the cylindrical body constituting the dust cover 34, that is, the edges 37 and 38 of the end plate of the cylindrical body are in contact with the frame body 39 of the crusher 6 positioned at the carry-out port 31 of the vibration feeder 21. When crushing the lump with the crusher 6, the fine crushing particles to be ejected from the inlet 24 of the crusher 6 are reflected by the inner surface of the cylindrical body of the dust cover 34 in the closed position and leaked to the outside. Is effectively prevented. Further, the dust cover 34 also functions to stop the introduction of the dust cover 34 into the crusher 6 even if a large lump that has been put into the hopper 16 but cannot be processed by the crusher 6 is supplied by the vibration feeder 21. Yes. Since the edge 36 at the other bus bar position of the cylindrical body is located at the carry-out port 31 of the vibration feeder 21, it does not contact the frame 39 of the crusher 6. On the other hand, for example, the central portion is cut out in an arc shape so that the inside can be visually observed so as not to hinder the charging of the lump into the crusher 6. In this way, the workers on the work scaffold provided around the crusher 6 are not exposed to dust or granular materials. Further, the dust cover 34 can be manually opened and closed around the rotation axis 35 by grasping a handle appropriately provided on the outer surface of the dust cover 34, and the carry-out port 31 of the vibration feeder 21 and the crusher 6 are turned on. Maintenance such as inspection and repair with the mouth 24 is facilitated.
0031]
  In order to prevent dust from being scattered between the vibration feeder 21 and the crusher 6, a large number of slits are preferably formed in the longitudinal direction between the outlet 31 of the vibration feeder 21 and the inlet 24 of the crusher 6 in a strip shape. The rubber curtain 40 containing is closed. Small crushed pieces and fine crushed particles generated during crushing of the lump are prevented from being ejected from the inlet 24 of the crusher 6 to the carry-out port 31 of the vibration feeder 21. Further, a row of chains 41 hangs down closely across the lateral width of the inlet 24 of the crusher 6 located inside the dust cover 34. The chain row 41 is arranged in the vicinity of the rotation axis 35 of the dust cover 34 and along the rotation axis 35. The lower end of the chain is not in contact with the bottom surface of the inlet 24 of the crusher 6 and has a small gap. When the lump is crushed by the crusher 6, the small crushed pieces blown off to the vibration feeder 21 side collide with the chain 41 and are returned to the inside of the crusher 6 again.
0032]
  The rotational driving force of the electric motor 42 provided on the gantry 135 fixed on the vehicle body frame 4 is transmitted to the crushing blade rotating shaft of the crusher 6 via the belt 43, and crushes the lump that has been charged. As the crusher 6, for example, a type such as an impact crusher or a jo crusher can be used. However, since the internal structure of the crusher 6 may be a known one, detailed description thereof is omitted here. Electric power to the motor 42 is supplied from the generator 8. It is preferable for safety to cover the belt 43 with a belt cover 44 attached to the crusher 6. The crusher 6 is supported on a frame 45 as a frame, and a vibration absorbing support 15 is interposed between the frame 45 and the vehicle body frame 4.
0033]
  The lower space of the crusher 6, which is surrounded by the frame 45, is provided with a lower vibration feeder 11 for supplying the granular material of the crushed material to the conveyor 10, and a lower vibration feeder 11. A transport conveyor 10 for transporting the crushed material and a scattering prevention device 53 for preventing dust from scattering to the outside when being supplied from the lower vibration feeder 11 to the transport conveyor 10 are provided.
0034]
  Similar to the hopper, the lower vibration feeder 11 includes a plate-like portion 46 having a converging structure in which a supply path becomes narrower as it goes downstream, a vibration motor 12 that applies vibration to the plate-like portion 46, and a support portion for the vehicle frame 4. It has become. The converging structure of the plate-like portion 46 is such that, at the bottom of the crusher 6, the bottom portion gradually sinks toward the front of the vehicle, that is, the conveyance direction of the conveyance conveyor 10, and also toward the center in the lateral direction of the vehicle left and right. The bottom part gradually sinks. A vibration motor 12 for generating vibration is attached to a substantially central bottom portion of the plate-like portion 46 via a bracket 49. The lower vibration feeder 11 supplies the lump that has been crushed by the crusher 6 so that the central ridgeline of the bottom of the convergence is extended by the vibration action, that is, concentrated in the center in the front and lateral directions of the vehicle. The mass is dropped from the opening 48 and transferred to the conveyor 10. Since the plate-like portion 46 is directly attached to the crusher 6 without leaving a gap after the lower cover that normally exists in the crusher 6 is removed, the vehicle height of the crushing plant vehicle can be increased. If the lower vibration feeder 11 is fixed integrally with the crusher 6, vibration from the crusher 6 is also received during operation of the plant. Therefore, the rubber sheet 47 attached to the outer surface of the lower vibration feeder 11 is attached to the crusher 6. It is connected to the periphery of the bottom to prevent resonance with the vibration of the vibration motor 12 and to prevent noise (FIG. 15). Since the load applied to the plate-like portion 46 cannot be supported only through the rubber sheet 47, the plate-like portion 46 is supported by the vehicle body frame 4 by the support columns 50 and 51 at appropriate positions at the four corners. A vibration absorbing support 15 used to support the vibration feeder 21 provided between the hopper 16 and the crusher 6 is interposed in the middle of the columns 50 and 51 constituting the gantry. The vibration to be generated is prevented from being transmitted to the vehicle body frame 4 and the generation of noise is suppressed.
0035]
  The anti-scattering device 53 that prevents dust from being scattered to the outside when being supplied from the lower vibration feeder 11 to the conveyor 10 tries to fly up when the crushed material is transferred from the lower vibration feeder 11 to the conveyor 10. It suppresses fine crushed particles as much as possible. As one of the scattering prevention devices 53, a distance along the transport path for a while from the transfer position of the crushed material from the lower vibration feeder 11 on the transport conveyor 10, that is, the plate-like portion 46 of the lower vibration feeder 11 is provided. A substantially semi-cylindrical dust-proof cover 54 that covers the transport conveyor 10 is provided for a while even after going out of the plate-like portion 46 from the opening 48. A plurality of strip-shaped rubber curtains 55 and 56 are provided at both ends of the dust-proof cover 54 in the transport direction of the transport conveyor 10 so that the upper ends are fixed to the dust-proof cover 54. It has been. The rubber curtains 55 and 56 in the form of strips allow a large crushed material to bend and allow the passage thereof, and prevent dust as crushed fine particles from being ejected to the outside or returning to the lower vibration feeder 11 side. A water injection nozzle 57 that sprays water toward the inside of the dustproof cover 54 through a hole formed in the upper center of the rubber curtain 56 is provided as one of the scattering prevention devices 53 in the immediate vicinity of the outlet of the dustproof cover 54. The water spray nozzle 57 prevents dust from rising in the dust cover 54. In the vicinity of the lower end of the rubber curtain 55 located on the inlet side to the dustproof cover 54, that is, on the lower side, excess water that has been sprayed by the water spray nozzle 57 and did not adhere to the dust is sucked and externally connected through a predetermined pipe. A sponge 58 for discharging is provided. Water to the water injection nozzle 57 is pumped up by a pump, that is, a sprayer 59 from a water tank 17 attached to the lower part of the vehicle body frame 4 of the vehicle, and supplied through a piping system 60. Further, as another scattering preventing device 53, a wall-shaped cover plate 61 is disposed around the opening 48 of the plate-like portion 46 with a slight gap with respect to the conveying surface of the conveying conveyor 10 inclined obliquely upward. It is placed in a non-contact state, leaving only dust, making it difficult for the dust to be ejected to the outside.

  The conveyor 10 is a flat belt conveyor type, and does not include a partition plate that increases the height like a bucket conveyor. The conveying conveyor 10 conveys the processing material, that is, the lump or crushed material discharged from the crusher 6 to the vibration sieve 7, and a lower vibration feeder 11 provided at the lower part of the crusher 6 and a hopper 13 of the vibration sieve 7. Is extended in an inclined state from the rear lower side toward the front upper side. The conveyor 10 may be a fixed type and does not need to be provided with an adjustment mechanism for height and expansion / contraction unlike a conventional conveyor, and as a result, contributes to reducing the overall height of the vehicle.
0037]
  Next, based on FIG.16 and FIG.17, the detail of the vibration sieve machine of this lump crushing plant car is demonstrated.. ShakeThe kinematic sieve 7 sieves the crushed material sent from the conveyor 10, carries out the granular material smaller than the specified size to the outside of the vehicle as a recycled product, and sends the granular material larger than the specified size back to the crusher 6. Is. The vibration sieve 7 is installed on a gantry 62 assembled on the vehicle body frame 4 in front of the vehicle. The vibration sieve machine 7 includes, as a vibration sieve plate 63, a perforated metal plate 64 in which a large number of holes 65 of a certain size are perforated and vibrated, and a frame 66 fixed to the perforated metal plate 64 so as to surround the periphery. have. The perforated metal plate 64 is arranged slightly inclined in the lateral direction of the vehicle, and conveys the granular material of the crushed material in the inclined downward direction with vibration. The crushed material from the conveyor 10 is dropped onto the upper slope of the perforated metal plate 64. The frame 66 is composed of a side wall 67 on the uppermost side of the inclined surface of the porous metal plate 64 and side walls 68 and 69 on both sides so that the crushed material fed from the conveyor 10 does not overflow. The discharge section 70 located at the lowest position on the slope of the vibration sieve 7 is open, and a return conveyor 14 that allows a large granular material that has not been shaken off by the porous metal plate 64 to run immediately adjacent to it. To be transferred to.
0038]
  Like the vibration feeder 21 and the lower vibration feeder 11, the vibration sieve 7 is forcibly vibrated by the vibration motor 72 and is buffered and supported by the vibration absorption support 15 with respect to the body frame 4. A vibration motor 72 is attached to the frame body 66 via a bracket 71, and the vibration sieve 7 is vibrated with the operation of the vibration motor 72, so that it contains water sprayed from the watering means and has adhesiveness. The raised granular material is transported in the downward direction of the feeder. The frame body 66 is buffered and supported by the gantry 62 via the vibration absorption support body 15 at appropriate plural places. Even if the vibration sieve 7 is vibrated greatly, the vibration is attenuated and transmitted to the gantry 62 and the generation of noise can be suppressed.
0039]
  The crushed granular material is sorted as it moves by vibration from the high region of the porous metal plate 64 to the lower discharge portion 70, and the crushed granular material falls through the hole 65 and falls to a predetermined size. The crushed material having the above size proceeds to the discharge portion 70 of the porous metal plate 64. The particulate matter dropped through the hole 65 falls directly onto the carry-out conveyor 18 through the hopper 74 and is carried out to a predetermined place outside the crushing plant car by the carry-out conveyor 18. The hopper 74 returns the outlet 76 to the side opposite to the side where the conveyor 14 is disposed on the vehicle body frame 4. In order to vibrate the hopper 74, a vibration motor 75 is attached to the bottom of the hopper 74. Since the conveying means such as the carry-out conveyor is not connected to the lower hopper of the vibration sieve 7 on the vehicle body frame 4 as in the conventional vibration sieve 7, the bulk of the vibration sieve 7 can be reduced.
0040]
  Further, the partition plate 74a in an inclined state is provided integrally with the hopper 74 so as to divide the inside of the hopper 74 back and forth in the supply direction of the porous metal plate 64 of the vibration sieve 7 so that vibration from the vibration motor 75 can be reduced. It is transmitted to the entire hopper 74. Accordingly, the particulate matter dropped from the hole 65 before and after the supply direction of the porous metal plate 64 of the vibration sieve 7 is divided into the inner wall chute surface of the hopper 74 and the inclined surface of the partition plate 74a, and both are vibrated. Since it is sent to the hopper outlet 76, the phenomenon that the particulate matter is deposited on the inner wall chute surface of the hopper 74 and does not flow does not occur. Since the partition plate 74a has an integral structure with the hopper 74, compared to a case where the partition plate 74a is assembled and configured, leakage of crushed particles from the joint portion with the hopper 74 into and out of the hopper 74 is eliminated. Further, the partition plate 74a integrally formed with the hopper 74 has low noise during operation, but a rubber plate can be attached to the rear surface of the partition plate 74a to suppress the collision noise between the crushed material and the partition plate 74a.
0041]
  Next, based on FIG.18 and FIG.19, the return conveyor and the return part to a crusher are demonstrated.. ThisIn the lump crushing plant vehicle, the return conveyor 14 extending between the lower portion of the discharge portion 70 of the vibration sieve plate 63 and the upper portion of the vibration feeder 21 of the crusher 6 is provided. The return conveyor 14 performs a function of receiving a crushed material having a predetermined size or larger that could not pass through the hole 65 of the perforated metal plate 64 at the discharge unit 70 and returning the crushed material to the crusher 6 again. Although it is substantially parallel to the transport conveyor 10, it is installed with the inclination and the transport direction reversed. The return conveyor 14 for feeding the crushed material into the hopper 16 is fixedly installed, and the height of the hopper 16 side of the crusher 6 is naturally fixed. Since the discharge portion 70 of the vibration sieve plate 63 is at a higher position than the conventional one, the carry-in side of the return conveyor 14 can be provided at the middle height position of the vibration sieve machine 7. In response to this, it is possible to connect the return exit 14 of the return conveyor 14 to the return hopper 79 in a relatively low posture, and to suppress the ground height of the crusher 6 and peripheral devices.
0042]
  The state in which the granular material having a size larger than the specified size is returned to the vibrating feeder 21 of the crusher 6 from the outlet 78 of the return conveyor 14 is also shown in FIGS. A return hopper 79 is connected to the nearest position of the hopper 16 on the front side of the vehicle at a position slightly lower than the top of the hopper 16 of the crusher 6. The carry-out port 78 of the return conveyor 14 faces a position directly above the return hopper 79, and the height of the carry-out port 78 is equal to or slightly below the height of the hopper 16. Accordingly, the return conveyor 14 does not directly interfere with the hopper 16 of the crusher 6 and does not increase the overall height of the vehicle. The return hopper 79 extends in a direction orthogonal to the conveying direction of the return conveyor 14, that is, in the lateral direction of the vehicle, and is integrally engaged with the side portion of the vibration feeder 21. The crushed material input path of the return hopper 79 joins the conveying path of the vibration feeder 21 at right angles. The crushed material of a size larger than the specified size returned by the return conveyor 14 is put into the return hopper 79 from the carry-out port 78, and halfway through the conveying path from the return hopper 79 to the vibration feeder 21 due to vibration transmitted from the vibration feeder 21. Into the crusher 6.
0043]
  Next, the details of the carry-out conveyor will be described with reference to FIGS.. CarryingThe delivery conveyor 18 carries out the recycled granular material discharged from the hopper 74 of the vibration sieve 7 to the outside of the vehicle. The carry-out conveyor 18 is rotatable around the vertical axis at the lowest position facing the outlet 76 of the hopper 74. The vehicle body frame 4 can be engaged with the vehicle body 4 so that the posture can be maintained at a predetermined rotational position. A vertical shaft 81 provided on the lowermost frame 80 of the carry-out conveyor 18 is rotatable by a bearing 82 with respect to the vehicle body frame 4. The frame 80 is integrally provided with a triangular plate 83 extending in the vertical direction on both sides, and one triangular plate 83 is further provided with a support plate 84 extending in the horizontal direction, through which the positioning pin 85 is inserted. A hole 86 is opened. The positioning pin 85 is connected to the other end of a chain 87 whose one end is connected to the frame 80 to prevent loss. The other triangular plate 83 is provided with a caster 88 that can roll on the vehicle body frame 4.
0044]
  Further, when the carry-out conveyor 18 rotates around the vertical axis 81, an arcuate positioning plate 89 is provided on the vehicle body frame 4 so as to face the locus drawn by the hole 86 of the support plate 84. The horizontal flange portion 90 of the positioning plate 89 has a plurality of holes 91 through which the positioning pins 85 can be inserted at appropriate intervals. During operation of the crushing plant, when the carry-out conveyor 18 is rotated around the vertical axis 81 by the caster 88 to determine the carry-out direction, the positioning pin 85 is inserted into the hole 86 of the support plate 84 and the horizontal flange of the positioning plate 89 at that position. Positioning is completed by inserting it into the hole 91 of the portion 90. If the ball bearing is configured by fitting the inner and outer surfaces of the sphere between the tip of the vertical shaft 81 and the bearing 82, the carry-out conveyor 18 can change not only turning but also the vertical undulation position. As shown in FIG. 17, the elevation angle of the carry-out conveyor 18 is determined by changing the length of the chain 94 that connects between the column 92 and the tip of the carry-out conveyor 18. The structure of the other carry-out conveyor 18 itself may be the same as that of the transfer conveyor 10.
0045]
  When the crushing plant is not in operation, such as when traveling on the road, the carry-out conveyor 18 is in a storage state parallel to the transfer conveyor 10 on the opposite side of the vehicle as shown in FIGS. Is done. A chain 94 connecting the tip end portion of the carry-out conveyor 18 is stretched over the top portion 93 of the support frame 92 integrated with the frame 62 integrated with the vehicle body frame 4. The chain 94 is divided into two forks from the middle, and the chain of each branch is engaged with the frames on both sides of the carry-out conveyor 18. Further, the engagement between the chain 94 and the top portion 93 can be released by the release means 95, and when the carry-out conveyor 18 can be raised and lowered, the length of the chain 94 can be changed. During operation of the crushing plant, as described above, the carry-out conveyor 18 is swung around the vertical shaft 81 and positioned in a predetermined carry-out direction outside the vehicle. In addition, the carry-out conveyor 18 is stably supported, and the support load of the carry-out conveyor 18 is shared so as not to be concentrated on the vertical shaft 81 and the support plate 84.
0046]
  Next, with reference to FIG. 22 to FIG. 25, the structure related to the input part to the crusher and the work scaffold in the vicinity thereof will be described in detail.In this lump crushing plant vehicle, as shown in FIG. 22, work scaffolds 100 on which workers can walk for inspection and repair of the crusher 6 and the hopper 16 are provided around the hopper 16 of the crusher 6.

Is provided. A handrail 119 made of an iron pipe is removably attached around the landing 118. When the vehicle is running, the handrail 119 is removed, and the total height of the crushing plant vehicle is adjusted to the safety standard. As a detachable attachment structure of the handrail 119, for example, by inserting the lower ends on both sides of the handrail 119 into a bottomed cylinder provided on the landing 118, an inexpensive and simple structure can be achieved. .
0049]
  As shown in FIG. 10, a transfer place 120 is provided between a work platform 100 provided around the hopper 16 and a landing place 118 provided at the top of the crusher 6. The worker can freely go back and forth between the work platform 100 and the landing 118 through the transfer place 120. The transfer place 120 is composed of a bottom plate and a side plate that can be rotated by a hinge with a wire netting plate, and can be compactly moved toward the hopper 16 so as not to be folded and increase the overall height of the vehicle.
0050]
  The vehicle is provided with ladders 121 and 122 as shown in FIGS. 10, 18 and 19 so that workers can climb the work platform 100 and the landing 118. The ladder 121 is made of a metal pipe, and one vertical pipe forming the ladder 121 can be rotated around the vertical axis by hinges 123 and 124 arranged vertically with respect to the frame 33.

0051]
  Further, the lump crushing plant vehicle has a structure that can use the doors, that is, the tilt plates 127 on at least both sides of the periphery of the vehicle body frame 4 as a work scaffold, as shown in FIGS. As shown in FIG. 4, a plurality of mounting brackets 128 such as U-shaped non-circular brackets are mounted on the outer wall surface in the longitudinal direction of the vehicle body frame 4 and are separately prepared. The character-shaped metal fitting 129 is configured to be detachable. For example, when the crushing plant is operated, if the tilt plate 127 provided on the vehicle body frame 4 so as to be tiltable with a hinge is tilted as shown by a chain line with the L-shaped bracket 129 mounted on the mounting bracket 128, the tilt plate 127 Is held in a horizontal state parallel to the floor surface of the body frame 4 and can be used as a scaffold. Instead of the mounting bracket 128 and the L-shaped bracket 129, a horizontal hole (not shown) is formed in the vehicle body frame 4 on the periphery of the loading platform, and a bar-like support (not shown) is fitted into the horizontal hole, and the tilt plate 127 may be configured to be horizontally supported, and both the ends of the tilt plate 127 are horizontally held in a state of being pulled by the vehicle body frame with the chain in the same manner as the chains 108 to 110 of the scaffolding plates 101 to 103 of the work platform 100.

There is a scaffold 134 at the top of the torii part 132, and it can be used by workers when inspecting and repairing the vibration sieve 7 and a water jet nozzle 97 described later.
0052]
  When a lump or crushed material moves between a processing machine such as a crushing machine 6 or a vibrating sieve 7 and a conveying means such as a vibrating feeder 21, a conveying conveyor 10, a return conveyor 14 or a carrying out means, Dust is scattered by the wind received during the fall and the impact during transfer. Accordingly, as already described as one of the scattering prevention means 53 with respect to the dust cover 54, the water transfer means is provided at such a transfer location, and water is sprayed in the form of mist on the scattered dust. Is suppressed. That is, a water tank 17 for storing water to be sprinkled is provided in the space under the vehicle body frame 4. The water stored in the water tank 17 is not only supplied through the water injection nozzle 57 of the splash preventing means 53 but also through the piping system by the water pump 59 provided on the body frame 4 and below the electric motor 42. Water is supplied to each place where dust is likely to scatter, and the mist-like water sprayed by water injection means such as a nozzle provided at the end of the piping system is prevented from scattering dust.
0053]
  One of the installation locations of the water injection means other than the location where the water injection nozzle 57 is provided with respect to the dust-proof cover 54 of the scattering prevention means 53 is first at a position where it is introduced into the crusher 6 from the outlet 22 of the vibration feeder 21. is there. The water injection nozzle 96 shown in FIG. 1 is provided at the edge of the hopper 16 of the crusher 6 in the vehicle front direction and injects water between the dustproof cover 34 and the vibration feeder 21. In addition, a water injection nozzle 97 that sprays water on the crushed material that is put into the vibrating screen 7 from the conveyor 10 is also provided at the top 93 of the gantry 62.

【The invention's effect】
  The lump crushing plant vehicle according to the present invention has the above-described configuration and has the following effects. That is, this lump crushing plant vehicle includes a crusher for crushing lump such as concrete, asphalt, etc., which is a waste material of buildings, structures, etc., a vibration sieve machine for selecting the crushed crushed material, and these A crushing plant equipped with a drive unit such as a generator that drives the equipment of this type is installed in a vehicle such as a normal truck, and it runs on roads that cannot be used not only on general roads but also on large tractor-trailer type vehicles. In consideration of vehicle width, height, and weight balance, the crushing plant is compactly configured to efficiently prevent generation of vibration and noise. 0056]
  In this lump crushing plant vehicle, the crushing plant is mounted on the body frame of the truck with a vibration absorbing support interposed therebetween, and the granular material in the crushing plant is transferred using a vibration motor of the vibration generating means. Since the vibratory feeder was used to supply the lump to the crusher, it was possible to average the supply to some extent by the conveying means so that a large amount of lump was not supplied from the hopper to the crusher at one time. As a means, a vibration feeder that does not have a return travel path that runs in the opposite direction to the transport travel path is used instead of the conventional transport conveyor, so the height dimension is short, and the entire hopper, vibration feeder, and crusher The height dimension of the will not increase.
0057]
  This lump crushing plant car has a lower plant height than the tractor-trailer crushing plant car, so there are special adjustment mechanisms such as changing the inclination angle of conveyors and hoppers and expanding and reducing the conveyor length. The vehicle height is configured to meet the safety standards without requiring the structure and operation required in conventional crushing plant vehicles such as installing and adjusting the vehicle. As long as the road can run on ordinary roads with the crushing plant loaded and equipped, the crushing plant can be easily transported to the site where the waste material to be crushed is generated, and crushed into the truck. It is possible to crush waste materials such as concrete and asphalt with the plant installed.
0058]
  Further, the crushed material of a predetermined size or more that is fed by the return conveyor is not returned to the hopper, but is returned to the vibrating feeder provided between the hopper and the crusher. Therefore, the return conveyor can be installed without bringing the return conveyor outlet to a position exceeding the height of the hopper, and there is no concern of increasing the overall height of the apparatus. Moreover, since there is no structural interference between the lump feeding hopper and the return conveyor, the hopper structure is simplified and the top height of the return conveyor is lowered as seen in conventional crushing plant vehicles. It is not necessary to provide a conveyor inclination changing device for changing the inclination angle of the return conveyor, and as a result, it is not necessary to change the conveyor inclination angle at the start or end of operation of the crushing plant. The installation height of the hopper, which is the height of the vehicle, can be configured to meet the safety standards, so that it is possible to travel on the road with the crushing plant installed in the body frame. Therefore, this lump crushing plant car is transported to the site where crushed materials such as concrete and asphalt are generated with the crushing plant installed, and the crushing material is immediately crushed with the crushing plant installed on the body frame. Therefore, the crushing process can be performed efficiently without taking time for the work setup.
0059]
  In addition, an anti-vibration cover that can be opened and closed across the exit of the vibratory feeder and the inlet to the crushing machine is provided, so that not only the fragments of the crushing object generated by the crushing machine but also the crushing object is crushed. It is possible to prevent dust generated when the dust is scattered. In addition, a large lump that cannot be processed by the crusher is stopped by the anti-vibration cover so as not to be put into the crusher. Since the anti-vibration cover is configured to be openable and closable, there is no problem in operations such as inspection and repair of the vibration feeder and the crusher.
0060]
  Further, in this lump crushing plant vehicle, the vibration feeder, the crusher, the vibration sieve machine, and the like are attached to the vehicle body frame via a vibration absorbing support of a vibration isolating material such as a rubber body. Therefore, the vibration of the vibration source is not transmitted directly to the vehicle body frame, and vibration and noise generated by the crushing plant during crushing work can be reduced. It is necessary to manufacture or modify the chassis to a special structure that attaches the chassis to the rear wheel via an air cushion and leaf spring, or reinforces the frame like a conventional crushing plant carButInstead, it is possible to use a truck vehicle in which a normal shock is applied between the body frame of the truck and the wheels. As a result, the overall height of the vehicle can be lowered and the manufacturing cost can be reduced.
0061]
  Furthermore, a pair of motors that generate an unbalanced force accompanying the rotation of the rotating shaft as vibration generating means of the vibration feeder are attached to the lower surface of the vibrating feeder symmetrically with respect to the center line in the vibration supply direction, and the rotating shaft is Since the phases of the unbalanced forces are opposite to each other so as to be symmetric with respect to the center line of the vibration supply direction, a vibration motor is used as an inexpensive vibration generating means, and its arrangement and operation mode are specified. By doing so, the granular material can be supplied most efficiently by the vibration feeder. Even if the phase of the unbalance force direction is shifted,oneExperience has confirmed that even if the rotation direction of the pair of vibration generating motors is the same direction, the efficiency of supplying the lump deteriorates.
