2. Description of the Related Art In recent years, especially in urban areas, middle and high-rise houses, buildings, structures, etc. have been demolished or rebuilt for redevelopment of areas where many buildings have already been constructed, such as residential areas and urban areas. Work may be performed. It is necessary to treat the lumps of concrete, asphalt, etc. generated at that time, but the dumping treatment, which is a common treatment method, has gradually become difficult to secure a place for legally dumping lumps. As a result, it can no longer be easily adopted. Therefore, waste materials such as buildings and structures, concrete,
A method has been adopted in which lumps such as asphalt are reused, that is, recycled and resources are effectively used to reduce the amount of waste. In particular, crushing lumps of concrete, asphalt, etc. with a crusher and reusing the crushed materials as recycled materials such as road surface materials, foundation materials for structures, structures, backfill materials after excavation, etc. Came to be done.

Crushing of lumps of concrete, asphalt, waste materials, etc. is performed at the site where the lumps are generated, and the crushed particles obtained at the site are transported to a predetermined place and used as recycled products. This is preferable for environmental protection and effective use of resources. It is no longer necessary to find a landfill disposal site or a dumping place for these lumps and transport them for a long distance by a vehicle or the like, and the environmental destruction due to the dumping of the lumps does not occur. In addition, if the crushed granular material is used as a recycled product, the amount of limited resources, such as gravel, can be reduced.

Conventionally, most of the crushing plants for crushing lumps of concrete, asphalt, waste materials, etc., are installation type crushing plants which are installed and used in a treatment plant.
The trailer is equipped with a crusher and its accompanying vibration sieving machine, generator, conveyor, etc., and transported to a specified processing site, and the crusher, etc. is set down from the trailer at the lump disposal site, and the processing site is also installed. The current situation is that they carry lumps up to. Such a crushing plant is basically composed of a crusher for crushing lumps such as concrete, asphalt, waste materials, a sorting mechanism for selecting the crushed crushed substances, and a driving device such as a generator. In addition, mobile crushing plant vehicles that can move inside the treatment plant have been developed for the crushing plant, but these mobile crushing plant vehicles are only moved at the treatment plant, and legally, they are on a general road. I couldn't drive.

By the way, the present applicant has already proposed a crushing plant vehicle which has a crushing plant installed on a trailer capable of traveling on the road, and which meets the safety standards of the Road Transport Vehicle Act (for example, Japanese Patent Laid-Open No. 6-254429). (See the official gazette). The crushing plant vehicle is composed of a tractor and a trailer for road traveling equipped with an engine, and a crusher for crushing waste materials such as buildings and structures, lumps such as concrete and asphalt, and crushed crushed materials. A crushing plant consisting of a vibration sieving machine, a return conveyor, a conveyor, and a driving device such as a generator that drives these equipments is installed on a trailer so that it can meet the safety standards, and furthermore, the crushing plant in urban areas, urban areas, etc. It is possible to minimize the generation of noise, vibration, etc.

[0006]

However, the crusher plant vehicle described above is a tractor even if it is a vehicle that can meet the safety standards and meet the safety standards by satisfying the restrictions such as the width and height of the vehicle. And a trailer towed by the tractor. Therefore, there is a limit to the roads that the crushing plant car can drive, and if the road to access the crushing work place is a narrow road in an urban area, the crushing plant car must go to the crushing work place. There are some things you can't do. In addition, the above crushing plant car is
Since it is installed on the body frame consisting of the chassis and the reinforcement frame, it suppresses the generation of noise from the body frame during the operation of the crushing plant and avoids the vibration generated in the above equipment from being directly transmitted to the rear wheels. Therefore, it is necessary to mount the chassis to the rear wheel via an air cushion and a leaf spring. In the trailer, the structure of the vehicle body frame itself has to be a special structure in which a reinforcing frame, an air cushion and a leaf spring are incorporated.

The following structure is adopted for the vibration sieving machine in the conventional crushing plant vehicle. That is, in the vibrating screener, the crushed material from the crusher sent from the conveyor is put into the screen through the hopper. The sieve has a high inlet on the side of the hopper, is installed in a state of being inclined downward in the width direction of the vehicle, and an outlet is formed at the lower end. Therefore, the crushed material is sorted by the sieve as it vibrates from the high area of the sieve to the discharge portion on the lower side, and the crushed material crushed to a size below a predetermined size falls through the sieve,
It falls through the hopper onto a carry-out conveyor provided below the vibrating screener and on the body frame so as to run in the width direction of the body frame. The carry-out conveyor is installed so as to be slidable in the width direction of the vehicle body frame, and is slid when discharging the crushed material and brought to a position where one side projects outside the vehicle body frame.
The carry-out conveyor brought to the protruding position is connected to a carry-out chute pivotally attached to the outside of the vehicle body frame, and the exit of the carry-out chute is further installed on the site outside the crushing plant vehicle. Conveyor is connected. When discharging the crushed material from the vibrating screener, the discharge chute is rotated downward and fixed, and the crushed material carried from the carry-out conveyor is discharged through the discharge chute to the discharge conveyor installed on site. Further, when the vehicle travels on the road, if the discharge chute is rotated upward and then locked at a predetermined place by an appropriate means, the minimum ground clearance can be secured, and the vehicle can travel on the road. Like On the other hand, a crushed product having a size larger than a predetermined size advances to the discharge part of the screen, is returned to the crusher by the return conveyor traveling immediately below the discharge part, and is crushed again.

Therefore, the above-mentioned conventional vibration sieving machine for a crushing plant vehicle has the following bulkiness and complicated structure. That is, the crushed material sorted by a sieve and crushed to a size smaller than a predetermined size is passed through a hopper,
It falls on a carry-out conveyor provided below the vibrating screener and on the body frame so as to run in the width direction of the body frame. The carry-out conveyor has a bulky structure that requires a traveling section and a forwarding section in the middle. Therefore, the height is increased by the sum of the heights of the hopper and the carry-out conveyor. Further, since the carry-out conveyor is slidable with respect to the vehicle body frame and the discharge chute is pivotally attached to the vehicle body frame, the structure becomes complicated due to the provision of these movable parts.

Further, in the above conventional crushing plant vehicle, the vibrating sieving machine is only installed on the vehicle body frame with a vibration isolating member such as rubber interposed, and is related to the support of the vibrating sieve. There were some inadequate measures for vibration and noise.

[0010]

According to the present invention, a sieve plate with a frame made of a perforated metal plate or the like and a hopper having a hopper inclined surface attached below the sieve plate are integrated into an extremely compact structure. Then, the granules are satisfactorily and smoothly separated and sorted on the sieve plate vibrated by the vibration generating means, and the granules of a predetermined size or less are shaken off from the sieve plate and at least a predetermined amount from the lower end of the sieve plate or more. The present invention relates to a vibrating sieving machine which discharges the granular material of the above size and does not require a separate conveyor or the like for sending the granular material below the hopper.

According to the present invention, there is provided a sieve plate with a frame which is vibrated by vibration generating means which is supported on a pedestal in an inclined state, and a hopper having a hopper inclined surface attached below the sieve plate, By vibrating the sieve plate by the vibration generating means to move the granular material along the inclined surface of the sieve plate, the granular material of a predetermined size or less is shaken off by the sieve plate and a predetermined amount from the lower end side of the sieve plate. Discharging the particles of the above size, and discharging the particles of a predetermined size or less shaken off by the sieve plate to the particles discharging means along the hopper inclined surface by the vibration generating means, Vibrating screener.

Further, the sieve plate and the hopper are supported by the frame via a vibration absorbing support. Further, the sieve plate is composed of a porous metal plate. In particular, in the vibrating screener, a part of the particulate matter falling from the sieve plate in the hopper is guided to a partition plate installed in an inclined state in the hopper and transferred to the vicinity of the particulate matter discharging means. It is something.

Alternatively, according to the present invention, a hopper into which lumps are put, a crusher that crushes the lumps fed from the hopper into granules, and a frame on a vehicle body frame via a vibration absorbing support. Supported by the vibrating screener for selecting the granules according to size, a conveyor for conveying the granules from the crusher to the vibrating screener, and a granular material of a predetermined size or more selected by the vibrating screener again. A return conveyor for sending from the vibration sieving machine to the crushing machine for crushing, a particulate matter discharging means for discharging the particulate matter of a predetermined size or less selected by the oscillating sieve machine to the outside, and a drive device for driving these devices. And a crushing plant using the oscillating sifter according to any one of claims 1 to 5, which is mounted on a vehicle. About.

Further, in this lump crushing plant car, the oscillating feeder for transferring lumps from the oscillating sieving machine, the crushing machine and the hopper to the crusher has a vehicle body frame or a pedestal with a vibration absorbing support interposed. Supported by.
The vibration absorbing support is composed of a solid rod-shaped rubber body and a spring embedded spirally in the longitudinal direction of the rod-shaped rubber body, and has locking holes at both ends of the rod-shaped rubber body.

Further, in this lump crushing plant car, a vibrating feeder for transferring lumps from the hopper to the crusher, the crusher, a lower vibrating feeder provided under the crusher, and the vibrating screener, respectively. The vibration generating means is provided with a pair of motors, which generate an unbalanced force due to the rotation of the rotating shaft, symmetrically attached to the lower surface of the hopper with respect to the center line of the vibration supply direction, and the rotating shaft has the unbalanced force. Are composed of vibration motors that rotate in opposite directions so that their phases are symmetrical with respect to the center line of the vibration supply direction.

In this lump crushing plant vehicle, the vibrating feeder, the crushing machine, the conveyor, the vibrating screener and / or the carry-out conveyor are provided with water jet nozzles for preventing dust from scattering. Therefore, it is possible to effectively prevent the scattering of dust due to fine powder generated during the crushing of the lumps generated from the lump crushing plant car itself, and the dust generated when the granular substances are transported or discharged.

In this lump crushing plant vehicle, a truck can be used as the vehicle. This lump crushing plant car does not install a conventional crushing plant on a tractor and a trailer type large-sized vehicle, but rather a structure in which various equipments of the compacting crushing plant are related to each other and a supporting structure for the vehicle, in particular By devising the structure of the vibrating screener and the configuration related to the crushed material discharge means,
A crushing plant can be installed on an ordinary truck, enabling traveling on narrow roads.

According to this lump crushing plant car, the lumps put into the hopper are crushed by the crusher and supplied to the conveyor. The conveyer conveys the crushed material to the vibrating screener, and the crushed material of a size larger than the predetermined size selected by the vibrating screener is fed again from the vibrating screener to the crusher by the return conveyor for crushing again. The crushed material having a size smaller than a predetermined size selected by the vibrating screener is discharged to the outside by the crushed material discharging means. The vibrating screener has a vibrating screen plate that vibrates and supplies the crushed material on the downward slope of the perforated metal plate to be vibrated, and the crushed material of the predetermined size or less is formed in the perforated metal plate. And the crushed material having a size equal to or larger than the predetermined size is supplied from the tip of the slope to the return conveyor. Further, the crushed substances of the predetermined size or less that have been sieved are gathered by the vibrating hopper toward the inclined base end side of the perforated metal plate, and are supplied to the crushed substance discharging means from the outlet of the hopper. . Further, the above-mentioned crusher, lower vibrating feeder, vibrating sieving machine, conveyor, return conveyor and drive devices such as a generator for driving the crushed material discharging means are mounted on the body frame of the truck. .

Therefore, according to the agglomerate crushing plant vehicle of the present invention, the structure from the vibrating screener to the crushed material discharging means is simplified and the height required for such a structure is reduced. That is, since the crushed material of the predetermined size or less selected by the vibrating sieve plate is directly supplied to the crushed material discharging means mounted on the vehicle body frame by the vibrating hopper, a bulky carry-out conveyor or Since the discharge chute that is pivotally supported is not used, the height dimension of the vibrating screener on the vehicle body frame is shortened, and the structure from the vibrating screener to the crushed material discharging means is simplified.

In order to vibrate the vibrating screen plate of the vibrating screener or the hopper provided in the lower part of the vibrating screener, a normal vibration motor may be appropriately attached. The crushed material supplied from the crusher to the vibrating screener via the conveyor is sprayed with water to prevent dust from scattering and becomes considerably wet.The vibrating screener and hopper vibrate as described above. Therefore, even a crushed product having a size not larger than the predetermined size does not remain attached to the porous metal plate or the inner surface of the hopper, and is averaged to some extent and supplied to the discharging means.

When a vibrating motor is installed to vibrate a vibrating screen plate of the vibrating screener or a hopper provided in the lower part of the vibrating screener, vibration generated by the vibrating screener or the hopper during operation of the crushing plant is applied to the body frame. According to the present invention, since the vibration sieve plate is supported by the vibration absorbing support body with respect to the pedestal on the vehicle body frame side, a vibration sieve machine or a hopper is generated. Vibration
It is absorbed by the vibration absorbing support and is not transmitted to the crushing plant equipment via the vehicle body frame or the vehicle body frame.

When the lower vibrating feeder 11 is integrally fixed to the crusher 6, the vibration from the crusher 6 is also received during the operation of the plant. Therefore, the rubber sheet 47 attached to the outer surface of the lower vibrating feeder 11 is attached to the crusher 6. By connecting to the periphery of the bottom, resonance with the vibration of the vibration motor 12 is prevented and noise is also prevented (FIG. 15). Since the load applied to the plate-shaped portion 46 cannot be supported only through the rubber sheet 47,
The plate-like portion 46 is supported on the vehicle body frame 4 by 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 forming the gantry, and the vibration motor 12 is The generated vibration is prevented from being transmitted to the vehicle body frame 4, and the generation of noise is suppressed.

Dust that is crushed fine particles is prevented from spouting outside or returning to the lower vibrating feeder 11 side. Dust cover 54
In the immediate vicinity of the outlet of the water spray nozzle 57 as one of the scattering prevention devices 53, water is sprayed toward the inside of the dust cover 54 through a hole formed in the upper center of the rubber curtain 56.
Is provided. The water jet nozzle 57 prevents dust from rising in the dustproof cover 54. In the vicinity of the entrance to the dust-proof cover 54, that is, near the lower end of the rubber curtain 55 located on the lower side, the excess water that has been sprayed by the water spray nozzle 57 and has not adhered to the dust is sucked, and externally supplied through a predetermined pipe. A sponge 58 is provided to discharge the sponge. Water to the water injection nozzle 57 is pumped up from a water tank 17 attached to the lower portion of the vehicle body frame 4 of a vehicle by a pump or a sprayer 59, and supplied through a piping system 60. Further, as another one of the scattering prevention devices 53, a wall-shaped cover plate 61 is provided around the opening 48 of the plate-like portion 46, and a slight gap is formed between the conveyance surface of the conveyance conveyor 10 inclined obliquely upward. It is placed in a non-contact state, leaving only the dust, so that it is difficult for dust to blow out to the outside.

The transfer conveyor 10 is a flat belt conveyor type and does not have a partition plate for increasing the height like a bucket conveyor. Transport conveyor 10
Connects the lower vibrating feeder 11 provided at the lower part of the crusher 6 and the hopper 13 of the vibrating sifter 7 in order to convey the treatment material, that is, the lumps or crushed materials discharged from the crusher 6 to the vibrating sifter 7. Thus, the central portion of the vehicle in the longitudinal direction extends in an inclined state from the lower rear side toward the upper front side. The transfer conveyor 10 may be of a fixed type, and does not need to have a height and expansion / contraction adjusting mechanism like a conventional transfer conveyor, and as a result, contributes to reducing the overall height of the vehicle.

Next, the details of the vibrating screener of this crushing plant vehicle will be described with reference to FIGS. 16 and 17. 16 is a perspective view showing the upper part of the vibrating sieving machine in the lump crushing plant car of FIG. 1, and FIG. 17 is a side view showing the oscillating sieving machine and the carry-out conveyor in the lump crushing plant car of FIG. As shown in FIGS. 16 and 17, the vibrating screener 7 is
The crushed material sent from the transport conveyor 10 is sieved, the granular material smaller than the specified size is carried out as a recycled product to the outside of the vehicle, and the granular material larger than the specified size is sent back to the crusher 6. The vibrating screener 7 is installed on a frame 62 assembled on the vehicle body frame 4 in front of the vehicle. The vibrating sieving machine 7 serves as the vibrating sieving plate 63 in which a large number of holes 65 of a certain size are perforated and vibrated.
4 and a frame 66 fixed to the porous metal plate 64 so as to surround the periphery thereof. The porous metal plate 64 is arranged to be slightly inclined in the lateral direction of the vehicle, and conveys the granular material of the crushed material in the descending direction of the inclination with vibration. The crushed material from the transport conveyor 10 is the perforated metal plate 64.
It is dropped on the upper part of the slope. The frame 66 includes a side wall 67 on the uppermost side of the inclined surface of the porous metal plate 64 and side walls 68 on both sides,
69, and prevents the crushed material sent from the transfer conveyor 10 from overflowing. The discharge part 70 located at the lowest position on the slope of the vibrating screener 7 is opened, and the large-sized granular material which has not been shaken off by the perforated metal plate 64 is immediately adjacent to the return conveyor 14 to be run. Reprinted to.

Like the vibration feeder 21 and the lower vibration feeder 11, the vibration sieving machine 7 is forcibly applied with vibration by the vibration motor 72, and is buffered and supported by the vibration absorbing support member 15 with respect to the vehicle body frame 4. ing.
A vibration motor 72 is attached to the frame 66 via a bracket 71.
Is attached, and with the operation of the vibration motor 72,
The vibrating sieving machine 7 is vibrated and conveys the granular material of the crushed material containing the water sprayed from the water sprinkling means and having high adhesiveness in the descending direction of the feeder. The frame 66 is buffered and supported by the pedestal 62 via the vibration absorbing supports 15 at appropriate places. Even if the vibrating screener 7 is vibrated greatly, the vibration is attenuated and transmitted to the gantry 62, and the generation of noise can be suppressed.

The particles of the crushed material are sorted as they move by vibration from the high area of the porous metal plate 64 to the discharge portion 70 on the lower side, and the particles crushed to a predetermined size or less fall through the holes 65. Then, the crushed material of a predetermined size or more advances to the discharge portion 70 of the porous metal plate 64. The particulate matter that has passed through the hole 65 and dropped through the hopper 74 directly falls onto the carry-out conveyor 18, and is carried out by the carry-out conveyor 18 to a predetermined location outside the crushing plant vehicle. The hopper 74 brings the outlet 76 closer to the side opposite to the side where the return conveyor 14 is arranged on the vehicle body frame 4. A vibration motor 75 is attached to the bottom of the hopper 74 to vibrate the hopper 74. Unlike the conventional vibrating screener 7, since the carrying means such as the carry-out conveyor is not connected to the lower hopper of the vibrating screener 7 on the vehicle body frame 4, the bulkiness of the vibrating screener 7 can be reduced.

Further, the partition plate 74a in an inclined state is integrally provided with the hopper 74 so as to divide the inside of the hopper 74 into two parts in the supply direction of the perforated metal plate 64 of the vibrating screener 7, so that the vibration motor 75 Is transmitted to the entire hopper 74. Therefore, the particulate matter dropped from the holes 65 before and after the perforated metal plate 64 of the vibrating screener 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 not deposited and does not flow down on the inner wall chute surface of the hopper 74 does not occur. Partition plate 74a
Is an integral structure with the hopper 74, so the partition plate 7
4a is assembled and configured, the hopper 7
There is no leakage of crushed fine particles into or out of the hopper 74 from the joint portion with 4. Further, the partition plate 74a integrated with the hopper 74 generates less noise during operation, but a rubber plate can be attached to the back surface of the sloped surface of the partition plate 74a to suppress the collision noise between the crushed material and the partition plate 74a.

Next, referring to FIGS. 18 and 19, the returning conveyor and the returning section to the crusher will be described. 18 is an explanatory view showing a returning portion of the crushed material to the hopper by the return conveyor in the crushing plant car of FIG. 1 and a ladder from the vehicle body frame to the upper part of the crusher, and FIG. 19 is a use position of the ladder shown in FIG.

Therefore, the return conveyor 14
Does not directly interfere with the hopper 16 of the crusher 6 and does not contribute to increasing 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 vibrating feeder 21. The crushed material input path of the return hopper 79 joins the conveyance path of the vibration feeder 21 at right angles. The crushed product returned by the return conveyor 14 and having a size larger than the specified size is delivered to the outlet 7.

[0060]

The vibrating screener according to the present invention and the block crushing plant vehicle equipped with the vibrating screener have the above-mentioned structure,
It has the following effects. This lump crushing plant car is a hopper for charging lumps, a crusher for crushing the lumps put into the hopper to make crushed substances, a vibration sifter for selecting crushed substances according to size, and the crusher. A conveyor for conveying crushed materials from the oscillating sieve to the oscillating sieve, a return conveyor for transferring the crushed material of a predetermined size or more selected by the oscillating sieve to the crushing machine again for crushing again, the oscillating sieve A granular material discharging means for discharging the crushed material of a size smaller than a predetermined size selected by a machine to the outside, and a driving device such as a generator and an operation panel for driving these devices are installed on the body frame of the truck, and the vibration The sieving machine vibrates and supplies the crushed material on the descending slope of the sieve plate such as the perforated metal plate to be shaken, and crushes the crushed material of the predetermined size or less through the holes formed in the perforated metal plate and the slope. of It consists of a vibrating sieve plate that feeds the crushed material of the predetermined size or more from the end to the return conveyor, and between the vibration sieving machine and the crushed material unloading means, the size of the predetermined or less that has been shaken down. Since the crushed material is provided with a hopper which is brought to the upper end side of the inclined surface of the perforated metal plate by vibration to supply it to the crushed material discharging means, there is no need for a discharging means such as a separate conveyor at the bottom of the vibrating screener, The height of the structure from the vibrating screener to the particulate matter discharging means can be configured to be low, the structure of the vibrating screener itself can be made compact and simple, and it is convenient to mount it on vehicles such as trucks where space is restricted. .

This agglomerate crushing plant car has a structure up to discharging the crushed substances of a size smaller than the predetermined size selected by the vibrating sieve plate, and is forwarded to the running part and the intermediate part as seen in a conventional crushing plant car. Since a hopper that vibrates is directly supplied to the granular material discharging means without adopting a bulky structure requiring a section, crushed materials are discharged reliably and such a bulky carry-out conveyor is not used. Therefore, the height dimension of the vibrating screener on the vehicle body frame can be shortened. Further, neither a carry-out conveyor that is slidable in the width direction of the vehicle body frame is used, nor is a discharge chute having a movable support structure that is pivotally attached to the vehicle body frame is adopted. Since it is mounted on the upper part, the structure from the vibrating screener to the granular material discharging means is simplified, and the operation and preparation for discharging the granular material are greatly simplified.

This lump crushing plant vehicle is designed to be a truck type crushing plant vehicle by adapting the installation height of the crusher, which makes the height of the vehicle the highest, to the safety standard of the truck. Since the installation height of the vibration sieving machine can be set to a height that meets the safety standards, it is possible to drive on a relatively narrow road with the crushing plant installed in the body frame. Therefore, this lump crushing plant car is driven by the crushing plant installed on the vehicle body frame, if it is on a road where trucks can run, and carried to the site where crushed substances such as concrete and asphalt are generated, and the crushing plant is installed on the vehicle. With the installed state, you can immediately crush the crushed material,
It is possible to efficiently perform the crushing process without taking time to set up the work.

Since the crushed material is forcibly conveyed by the lower vibrating feeder, even when the lump contains water, the discharge hopper or the discharge hopper as found in the crushing plant vehicle previously proposed by the applicant of the present invention. It does not happen that the discharge chute does not adhere to the inner wall of the stationary guideway and cannot be peeled off. Therefore, there is no need to remove the adhered crushed material, and the efficiency of the crushing operation is improved.

Further, in this lump crushing plant vehicle, the vibration feeder, the crusher, the lower vibration feeder of the crusher, and the vibration sifter are vibrated by a rubber body in which a spring is embedded in the vehicle body frame or frame. Since the device is attached via the absorption support, the vibration generated in the device is absorbed by the vibration absorption support. As a result, it is possible to prevent unpleasant vibrations and noises from being transmitted to the vehicle body frame and adverse effects on other devices mounted on the vehicle body frame.
