BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant vehicle in which equipment can be mounted on a platform with a tilt.

[0002]

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 applicant of the present invention has already proposed a crushing plant vehicle which has a crushing plant installed on a trailer capable of traveling on the road and which complies with the safety standards of the Road Transport Vehicle Law (for example, Japanese Patent Laid-Open No. Hei 7-132242). (See the official gazette). The crushing plant vehicle has a crushing plant for crushing and reusing lumps such as concrete on a trailer, and in order to use the trailer's tilting plate as a work scaffold, tilt the tilting plate to make it almost flush with the floor. It is supported by a support member, and it is possible to attach a lifting ladder to the tilt plate with a simple structure locking tool, and tow a trailer equipped with crushing plant equipment such as a crusher with a tractor. It is configured so that it can run on a general road.

[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.

[0007] Further, although various kinds of operations such as trial run, repair, and cleaning of the crushing plant performed by the worker on the trailer are normally performed while the crushing plant vehicle is stopped, The tilt plate provided around the side and rear of the trailer is pivoted to a horizontal position for support, and a space is created on the tilt plate supported in the horizontal state to serve as a walkway or a work scaffold for workers' work. There is.
However, even if the tilt plate is used as a work scaffold, there is a problem in strength when it is tilted down and supported in a horizontal state. Therefore, it is required to stably support the tilt plate in a horizontal state and prevent damage to the tilt plate. To be done.

Also, when the side and rear tilt plates of the trailer are pivoted and supported to a horizontal position, the horizontal height of the plate is not such that an operator can ascend and descend by his / her own force, and must always move up and down. It is the height at which it is necessary to climb up and down using a ladder. By the way, the ground of the crushing plant is not always a flat and stable place, but is rather unstable due to unevenness, water pools, etc., or being weak. If a part of the lifting ladder is brought into contact with the edge of the tilting plate and placed on an unstable ground at the bottom, the lifting ladder leans laterally and the tilting plate tilts sideways as soon as the weight is applied to the lifting ladder. It is not possible to slide the edge of the sideways to the top of the tilt plate, and raising and lowering to the tilt plate is not preferable for safety reasons, and raising and lowering is dangerous, and the lifting ladder must be reinstalled. However, there is a problem that it takes time to move up and down the tilt plate.

[0009]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to drive a plant vehicle on which a device such as a crushing plant can be mounted on a tilted carrier so that it can comply with safety standards. It is possible to rotate the tilt that is pivotally attached to the floor frame to a position that corresponds to the floor surface, to support it stably and firmly, and to secure the lifting ladder to the tilt so that it can be pivotally attached, and the worker is safe. In order to reduce the vibration, noise, etc. generated by the operation of the crushing plant, it is possible to raise and lower with respect to the tilt, and the equipment is supported on the cargo bed by the body frame or frame via the vibration absorbing support. It is to provide a plant vehicle that can mount equipment on a platform with a tilt.

The present invention is directed to a plant vehicle having a body frame including a chassis which constitutes a vehicle such as a truck capable of traveling on a road equipped with an engine, and in which a device can be mounted on a tilting carrier formed on the body frame. A tilting pivotally attached to a floor frame located on the side of the vehicle of the body frame constituting the cargo bed so as to be tiltable, and can extend laterally along the body frame through an insertion hole formed in the floor frame. And a fixture for fixing the tilt support member to the vehicle body frame so that the tilt support member is supported in a tilted state corresponding to the floor surface of the cargo bed so as to use the tilt as a work scaffold. The present invention relates to a plant vehicle that can be equipped with a device on a tilted cargo bed. Therefore, the tilt can be placed on the tilt support member, and the tilt can be stably fixed in a substantially horizontal state, so that a worker can be provided with a work scaffold with high safety. Moreover, the tilt itself can be stabilized as a work scaffold by forming the tilt support member to have the same length as the tilt and optimally selecting the number of the tilt support members to be provided.

Further, in a plant vehicle in which equipment can be mounted on the platform with a tilt, the tilt support member is fixed to the floor frame or the body frame in a state where the tilt support member is accommodated along the body frame. Fixing means are provided. The fixing means is composed of a long member such as a chain or rope provided on one of the tilt support member and the floor frame and a long member locking device provided on the other. Therefore, while the vehicle is traveling, the tilt support member does not protrude laterally from the floor frame, and the vehicle can travel safely.

Further, the tilt support member formed in a hollow shape has a length through which the fix tool extends so that the tilt support member can be extended or stored from the vehicle body frame without interfering with the fix tool. A hole is formed. Therefore, the tilt support member can be slidably pulled out or stored while being smoothly guided with respect to the vehicle body frame.

Further, the tilt support member is provided with a cushion member such as rubber on the side on which the tilt is placed. Therefore, even when the tilt falls and collides with the tilt support member when the tilt is tilted on the tilt support member, the shock can be well buffered and the tilt and the tilt support member are prevented from being damaged. It is possible to reduce the impact noise.

Further, a ladder which can be assembled is detachably fixed to the tilt, and a support portion provided on the ladder is pivotally fixed to a pivot portion provided on the tilt. The pivot part can be attached to the optimum position of the tilt, and it can be provided at a plurality of positions, and in some cases, the pivot part can be provided so as to be movable with respect to the tilt, and the ladder is supported by the tilt. It can be installed at the optimum location. Moreover, since the ladder is fixed to the tilt, the safety of the operator can be secured.

Further, the vibration sieving machine as the device is a sieving machine main body which is supported by a frame via a vibration absorbing support and has inclined surfaces facing each other, a sieving plate attached to the sieving machine main body, and It comprises a vibration generating means attached to each of the inclined surfaces of the sieve body, driving the vibration generating means to vibrate the sieve body to screen the granular material with the sieve plate, with the sieve plate The particles having a size of not more than a predetermined size and the particles having a size of not less than a predetermined size that have been shaken off are respectively conveyed to different places by the conveying means. Furthermore, by attaching the sieve plate to the sieve body with an anti-vibration rubber interposed, it is possible to reduce the impact noise of metal members and suppress the generation of noise. Further, the vibration generating means mounts a pair of motors, which generate an unbalanced force due to the rotation of the rotating shaft, on the lower surface of the hopper symmetrically with respect to the center line of the vibration supply direction, and the rotating shaft is the unbalanced. The vibration motors are configured to rotate in opposite directions so that the phases of the forces are symmetrical with respect to the center line of the vibration supply direction. Therefore, since the vibration motor is provided on each of the inclined surfaces of the sieving machine main body, it is possible to smoothly drop the granular material to the discharging portion without retaining the granular material on the sieving plate and the sieving machine main body.

The equipment is fed by a hopper into which lumps are put, a crusher that crushes the lumps sent from the hopper by a vibrating feeder into granules, and a conveyor from the crusher. A vibrating screener for selecting the particulate matter, a return conveyor that forwards to the crusher from the vibrating screener for crushing again the granular material of a predetermined size or more selected by the vibrating screener, and the vibrating screener is selected. It is a crushing plant equipped with a particulate matter discharging means for discharging particulate matter of a predetermined size or less to the outside, and a drive device for driving these devices.

Further, the vibrating screener, the crusher, and the vibrating feeder are supported by the vehicle body frame or the pedestal through a vibration absorbing support. 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 has locking holes at both ends of the rod-shaped rubber body. Further, the vibrating feeder, the crusher, the conveyer conveyor, the vibrating screener and / or the carry-out conveyor are provided with water jet nozzles for preventing scattering of dust.

[0018] In this plant vehicle in which equipment can be mounted on the tilted loading platform, a truck can be used as the vehicle. This plant vehicle that can be equipped with equipment on a tilted loading platform does not install a conventional crushing plant on a tractor and trailer type large-sized vehicle, but rather on the structure and vehicle related to each other of various equipment of a compacted crushing plant. By devising the structure related to the support structure, the structure of the vibrating screener and the crushed material discharge means, the crushing plant can be mounted on a normal truck and it can run on narrow roads, especially tilting as a work scaffolding. Even if the plant vehicle is parked at any place by fixing it stably and firmly with the support member at a position corresponding to the floor surface, the operator can operate the equipment mounted on the plant vehicle and work. Can provide a safe and convenient scaffold. Moreover, since the ladder for raising and lowering is pivotally fixed to the tilt,
Even if the ladder does not reach the ground or the like, the worker can safely climb up and down the vehicle through the ladder.

According to the plant vehicle in which the equipment can be mounted on the tilted loading platform, 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. In particular, the vibration sieving machine is provided with vibration generating means respectively on the opposite inclined surfaces, so that the vibration is satisfactorily transmitted to the sieving plate and the sieving machine main body, and the crushed particulate matter is muddy by water injection or the like. Even if it is, the muddy granular material is not deposited on the inclined surface or the sieve plate, but descends well and is quickly vibrated and sorted by size. That is, 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, but the vibrating screener is added as described above. Since it is shaken, even a crushed product having a size smaller than or equal to the predetermined size does not remain attached to the porous metal plate or the inclined surface forming the sieve plate.

The crushed material of a size smaller than a predetermined size, which is 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 plant vehicle in which the equipment can be mounted on the tilted loading platform, 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.

When a vibration motor is installed to vibrate the vibrating screen plate of the vibrating screener or the hopper provided at 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 vehicle body frame. Although it may be transmitted to generate noise, since the vibrating screen plate is supported by the vibration absorbing support member with respect to the pedestal on the vehicle body frame side,
The vibration generated by the vibrating screener or the hopper is absorbed by the vibration absorbing support and is not transmitted to the other crushing plant equipment via the vehicle body frame or the vehicle body frame.

Next, the crusher and the lower vibrating feeder will be described with reference to FIGS. 14 and 15. 14 is an enlarged side view showing a lower vibrating feeder and a conveyer conveyor of the crusher in the plant vehicle of FIG. 1, and FIG. 15 is a rear view of the lower vibrating feeder of the plant vehicle of FIG.

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 dustproof cover 34 has a shape of a quarter of a cylindrical body as a whole. The dustproof cover 34 is rotatable with respect to the outer frame of the crusher 6 around an axis 35 extending in the lateral direction of the vehicle body, and the rotation axis 35 coincides with the generatrix of the cylindrical body. The edge of the cylindrical body that constitutes the dust-proof cover 34, that is, the edges 37 and 38 of the end plate of the cylindrical body are respectively the vibration feeder 21.
Since it abuts on the frame body 39 of the crusher 6 located at the carry-out port 31 of the crusher 6, the fine crushed particles which are about to be ejected from the input port 24 of the crusher 6 when the lump is crushed by the crusher 6, The dust-proof cover 34 in the closed position is reflected by the inner surface of the cylindrical body, and leakage to the outside is effectively prevented. Also,
The dustproof cover 34 has been put into the hopper 16, but the crusher 6
Even if a large lump that cannot be processed is supplied by the vibrating feeder 21, it also has a function of stopping charging into the crusher 6. The end edge 36 of the cylindrical body at the other generatrix position is located at the carry-out port 31 of the vibrating feeder 21 and is not in contact with the frame body 39 of the crusher 6. rather,
In order not to hinder the charging of the lumps into the crusher 6, for example, the central portion is cut out in an arc shape so that the inside can be viewed. In this way, the workers on the work scaffolds provided around the crusher 6 are not exposed to dust or particles. Further, the dustproof 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 dustproof cover 34, and the carry-out port 31 of the vibration feeder 21 and the crusher 6 can be loaded. Maintenance such as inspection and repair of the mouth 24 is facilitated.

In order to prevent dust from scattering between the vibrating feeder 21 and the crusher 6, a strip-shaped vertical direction is preferably provided between the carry-out port 31 of the vibrating feeder 21 and the input port 24 of the crusher 6. Rubber curtain 4 with many slits
0 is closed. Small crushed pieces and fine crushed particles generated when crushing the lumps are prevented from being jetted from the input port 24 of the crusher 6 to the carry-out port 31 of the vibrating feeder 21. Further, at the input port 24 of the crusher 6 located inside the dust-proof cover 34, a chain row 41 is hung in a dense arrangement along the lateral width thereof. The row 41 of chains is arranged in the vicinity of the rotation axis 35 of the dustproof cover 34 and along the rotation axis 35. The lower end of the chain is the input port 2 of the crusher 6.
There is no contact with the bottom surface of 4 and a small gap is provided. When the lumps are crushed by the crusher 6, the small crushed pieces that are blown off to the vibration feeder 21 side collide with the chain row 41 and are returned to the inside of the crusher 6 again.

Frame 135 fixed on the body frame 4
The rotational driving force of the electric motor 42 provided in the is transmitted to the crushing blade rotation shaft of the crusher 6 via the belt 43, and crushes the put-in lump. The crusher 6 may be of the type such as an impact crusher or a joch crusher. However, since the internal structure of the crusher 6 may be a known one, its detailed description is omitted here. Electric power to the electric motor 42 is supplied from the generator 8. It is preferable for safety to cover the periphery of the belt 43 with a belt cover 44 attached to the crusher 6. The crusher 6 is supported on a frame 45 as a mount, and a vibration absorbing support 15 is interposed between the frame 45 and the vehicle body frame 4.

In the lower space of the crusher 6 and in the inner space surrounded by the frame 45, the lower vibrating feeder 11 for supplying the granular material of the crushed lumps to the conveyor 10 and the lower vibrating feeder. There are provided a conveyor 10 for conveying the crushed material from 11, and an anti-scattering device 53 for preventing dust from scattering outside when the lower vibrating feeder 11 supplies the conveyor 10.

The lower vibrating feeder 11 is supported on the plate-like portion 46 having a converging structure in which the supply path becomes narrower toward the downstream like a hopper, the vibration motor 12 for vibrating the plate-like portion 46, and the vehicle frame 4. It consists of a section. In the lower part of the crusher 6, the converging structure of the plate-like portion 46 is such that the bottom part thereof gradually sinks as it goes in the vehicle front direction, that is, in the transport direction of the transport conveyor 10, and also in the lateral direction on the left and right sides of the vehicle toward the center direction. It is a structure in which the bottom gradually sinks. The 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 lumps crushed by the crusher 6 so that the central ridgeline of the bottom of the convergence is extended by the vibration action, that is, the lump is concentrated in the center in the vehicle front direction and the lateral direction, and is appropriately opened. The lump is dropped from the opening 48 and the lump is transferred onto the transfer conveyor 10. The plate-shaped portion 46 is directly attached to the crusher 6 without leaving a gap after the lower cover normally present in the crusher 6 is intentionally removed, so that the vehicle height of the crusher plant vehicle can be earned.
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.

From lower vibrating feeder 11 to conveyor 1
In the scattering prevention device 53, which prevents dust from scattering to the outside when it is supplied to 0, the crushed material is
This is to suppress as much as possible the fine crushed particles that are going to rise when transferred from the transfer conveyor 10 to the transfer conveyor 10. As one of the scattering prevention devices 53, on the transfer conveyor 10,
Between the transfer position of the crushed material from the lower vibrating feeder 11 and a distance along the transport path for a while, that is, the lower vibrating feeder 1
A substantially semi-cylindrical dust-proof cover 54 that covers the transport conveyor 10 is provided for a while even if it goes out of the plate-shaped portion 46 through the opening 48 of the plate-shaped portion 46 of No. 1. A plurality of slit-shaped rubber curtains 55, 56 are provided at both ends of the dust-proof cover 54 in the transport direction of the transport conveyor 10 in parallel with each other in the vertical direction, and the upper ends thereof are fixed to the dust-cover 54. Has been. Strip-shaped rubber curtains 55, 56
Bends to allow large crushed objects to pass through,
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, referring to FIGS. 16 and 17, description will be given of a vibration sifter in a plant vehicle in which equipment can be mounted on the tilted bed. 16 is a perspective view showing the upper part of the vibrating screener in the plant car of FIG. 1, and FIG. 17 is a side view showing the vibrating screener and the carry-out conveyor in the plant car of FIG.

The vibrating sieving machine 7 as a device screens the crushed material sent from the conveyor 10 and carries out the granules smaller than the specified size to the outside of the vehicle as recycled products, and the granules larger than the specified size. It 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 is a sieving machine main body 64 supported by a frame 62 via a vibration absorbing support body 15 and provided with facing inclined surfaces 65, and a sifter attached to the sieving machine main body 64 with a vibration absorbing rubber 69 interposed. The plate 63 and the vibrating motor 72 of a vibration generating means attached to each inclined surface 65 of the sieve main body 64 are provided. The sieve plate 63 is formed of, for example, a perforated metal plate having a large number of holes of a predetermined size and being vibrated, and the frame 66 is fixed so as to surround the perimeter of the perforated metal plate. The crushed material from the transport conveyor 10 is dropped onto the upper part of the slope of the sieve plate 63 which is a porous metal plate. The frame 66 is composed of a side wall 67 on the upper side of the perforated metal plate to prevent the crushed material sent from the transfer conveyor 10 from overflowing.

The vibrating sieving machine 7 drives the oscillating motor 72 to oscillate the sieving machine main body 64 to screen the granules with the sieve plate 63, and carry out the granules with a size smaller than a predetermined size which have been screened with the sieve plate 63. The particles discharged to the conveyor 18 and having a size larger than a predetermined size are discharged to the return conveyor 14. That is, the discharge section 70 located at the lowest position on the slope of the vibrating screener 7 is open, and the large-sized granular material that has not been shaken off by the screen plate 63 is immediately adjacent to the return conveyor. Reprinted in 14.

Like the vibrating feeder 21 and the lower vibrating feeder 11, the sieve main body 64 of the vibrating sieve 7 has an inclined surface 6
Vibration is forcibly applied by the vibration motor 72 attached to the vehicle body 5, and the body frame 4 is buffered and supported by the vibration absorbing support body 15. With the operation of the vibration motor 72, the vibration sieving machine 7 is vibrated and conveys the granular material of the crushed material, which contains water sprayed from the water sprinkling means and becomes highly sticky, in the descending direction of the feeder. Frame 66
Are buffered and supported on the pedestal 62 via the vibration absorbing supports 15 at appropriate positions. 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.

Granules of the crushed material are sorted by vibration from the high area of the sieve plate 63 to the discharge portion 70 on the lower side,
Granules crushed to a size smaller than a predetermined size pass through the holes of the sieve plate 63 and fall, and crushed products larger than a predetermined size are sieve plate 63.
To the discharge section 70 of the. The particulate matter that has passed through the sieve plate 63 and dropped falls directly onto the carry-out conveyor 18 through the hopper 74 constituted by the inclined surface 65, and the carry-out conveyor 18
Is carried out to a predetermined place outside the crushing plant car. The hopper 74 moves the outlet 76 toward the side opposite to the side where the return conveyor 14 is arranged on the vehicle body frame 4. Unlike the vibrating screener 7, since the conveying 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, since the partition plate 71 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 flow direction of the granular material of the vibration sieving machine 7, vibration from the vibration motor 72 is generated. Are transmitted to the entire hopper 74. Therefore, the granular material dropped from the sieve plate 63 before and after the granular material 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 71, and both are vibrated while the hopper exits. Since it is sent to the hopper 74, 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. Since the partition plate 71 is an integral structure with the hopper 74,
Compared with the case where the partition plate 71 is assembled and configured, leakage of crushed fine particles into and out of the hopper 74 from the joint with the hopper 74 is eliminated. Further, the partition plate 71 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 71 to suppress the collision noise between the crushed material and the partition plate 71.

Next, with reference 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 plant vehicle of FIG. 1 and a ladder from the vehicle body frame to the upper portion of the crusher, and FIG. 19 shows the use position of the ladder shown in FIG.

Is provided. The return conveyor 14 discharges the crushed material of a predetermined size or more that could not pass through the sieve plate 63.
The function of receiving the crushed material and returning the crushed material to the crusher 6 again is performed, and it is installed substantially parallel to the transfer conveyor 10 but with the inclination and the transfer direction reversed. Hopper 16
The return conveyor 14 for throwing the crushed material into the inside is of a fixed type, and the hopper 16 side of the crusher 6 is naturally of a fixed height. Since the discharge part 70 of the vibrating screen plate 63 is located higher than the conventional one, the carry-in side of the return conveyor 14 can be provided at the middle height position of the vibrating screener 7. In response to this, the carry-out port 78 of the return conveyor 14 can be connected to the return hopper 79 with a relatively low posture, and the ground height of the crusher 6 and the peripheral equipment can be suppressed.

The state in which the granular material having a size larger than the specified size is returned from the carry-out port 78 of the return conveyor 14 to the vibrating feeder 21 of the crusher 6 is also shown in FIGS. 11 and 12. A return hopper 79 is provided so as to connect to the hopper 16 at a position closest to 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 the position directly above the return hopper 79, and the height of the carry-out port 78 is equal to or slightly lower than the height of the hopper 16. 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.
8 is fed into the return hopper 79, and due to the vibration transmitted from the vibrating feeder 21, it flows from the return hopper 79 into the midway of the conveying path of the vibrating feeder 21 and is fed again into the crusher 6.

The plant vehicle according to the present invention, which can be equipped with equipment on the tilting carrier, has the above-mentioned configuration and has the following effects. Since this plant car is configured compactly as described above, it can be equipped with a crushing plant on a truck so that it can run even on narrow roads, and a plant car that can install equipment such as a crushing plant on a tilted loading platform is a low standard. It can be configured to be roadable so that it can be fitted. In particular, this plant car can be used as a work platform, even if it is parked at any place by stably and firmly fixing it with a support member at a position corresponding to the floor by tilting the tilt. It is possible to provide a safe and convenient scaffold for the workers to operate and work the equipment installed in the, and furthermore, since the ladder for raising and lowering is pivotally fixed to the tilt, even if the ladder does not reach the ground etc. Also, the worker can safely climb up and down the vehicle through the ladder.

Further, this plant car does not require a separate discharging means such as a conveyor at the lower part of the vibrating screener, and 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 sieving machine itself is compact and simple, which makes it convenient to mount on a vehicle with space restrictions such as trucks.Since a vibration motor is installed on each of the facing inclined surfaces of the sieving machine body, the hopper wall It is possible to prevent the particulate matter from accumulating in the powder and to smoothly discharge the particulate material. In addition, this plant car requires a traveling part and a forwarding part in the middle as seen in the conventional crushing plant car as a structure until discharging the crushed substances of the predetermined size or less selected by the vibrating sieve plate. Since it is directly supplied to the granular material discharging means by the vibrating sieving machine main body without adopting a bulky structure that makes it possible to reliably discharge the crushed material, and not to adopt such a bulky carry-out conveyor, The height dimension of the vibrating screener on the 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.

Further, since the crushed material is forcibly conveyed by the lower vibrating feeder, even when the lump contains water, the discharge as seen in the crushing plant vehicle previously proposed by the applicant of the present application. It does not occur that the inner wall of a stationary guideway such as a hopper or a discharge chute does not adhere to the inner wall 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. In addition, in this lump crushing plant vehicle, a vibration feeder, a crusher, a lower vibration feeder of the crusher, and a vibration sieving machine are used for a vehicle body frame and a frame, and a vibration absorbing support body made of a rubber body in which a spring is embedded inside. Since it is attached via
The vibration generated by the device is absorbed by the vibration absorbing 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.
