It can be appropriately adopted depending on the properties of the lump.

The lumps are often concrete blocks containing reinforcing bars, but if large reinforcing bars are thrown into the crushing machine 6, the metal blades for crushing will be damaged, so a viewpoint of protecting the crushing machine 6 Therefore, it is necessary to put only the concrete block from which the reinforcing bars have been removed into the crusher 6. Since the work efficiency will be reduced if the attachment handled by the concrete block and the reinforcing bar is exchanged, for example, if an electromagnet is provided in the upper center of the attachment or the attachment claw can be magnetized with the electromagnet, the concrete block can be attached to the concrete block. After squeezing and crushing to separate the rebar from the concrete, it is possible to adsorb only the rebar with the electromagnet part of the same attachment and move it to another place. Power for operating each boom of the crane 80 and power and power for operating the attachment are supplied from a drive source 8 described later.

The crane 80 is stored in the inner boom 88.
And the outta boom 90 are folded, and both booms 88 and 90 are folded together with the main post 84 so as to be aligned substantially in the width direction of the vehicle, so that the length of the crushing plant vehicle in the front-rear direction is made longer than necessary. Can be avoided. Also, in the folded state, the crane 80
Is set so that it does not extend beyond the width of the vehicle and does not exceed the height of the loading hopper 16 of the crusher 6 even in the height direction. It is filled.

Also, since the attachment is attached to the tip of the crane 80,
Depending on the type of attachment, it is possible to grab the lumps corresponding to many types of lumps and put them into the crusher 6.

The details of the conveyor 10, the vibrating screener 7, the return conveyor 14, etc. can be configured in the present invention in the same manner as the invention disclosed in the above-mentioned prior application by the present applicant. These details will be described below. 12 is a plan view showing an example of a telescopic mechanism of a conveyor in the crushing plant vehicle shown in FIG. 1, and FIG.
14 is a front view showing an embodiment of a discharge part of a vibrating screener in the crushing plant car, FIG. 14 is a front view showing an example of a return conveyor elevating mechanism in the crushing plant car in FIG. 1, and FIG. 15 is a crushing plant in FIG. Sectional drawing which shows an example of the horizontal support part of the tilt plate of the vehicle body frame in a vehicle, and FIG.
It is a perspective view which shows another Example of the horizontal support metal fitting of a swing plate.

The crusher 6, the vibrating screener 7, etc. are operated with the rear wheel 3 in contact with the ground, and in particular, one of the forces such as impact force and vibration generated by the crusher 6 when crushing crushed materials such as concrete and asphalt. The part is configured to absorb and absorb with an air cushion and a leaf spring included in the trailer 2 itself. Therefore, a part of the force such as the impact force and the vibration generated in the crusher 6 is buffered and absorbed by the air cushion and the leaf spring, so that the noise and vibration generated by the operation of the crushing plant vehicle are reduced to the minimum. In addition, it is possible to prevent a momentary excessive force from acting on the rear wheel 3. Further, the trailer 2 has a rear support column 78 at the rear portion of the vehicle body frame 4, which can be expanded and contracted by hydraulic pressure, a link, a screw or the like, in order to support a force such as an impact force or a vibration generated by the crusher 6 which is greater than a predetermined value. It is provided. Therefore, the rear support column 78 is almost grounded when the crusher 6 is operating, or is extended to the grounded state with a floor plate or the like, and supports the vehicle body frame 4 when an excessive load is applied to the trailer 2 by the crusher 6. However, the air cushion and the leaf spring of the trailer 2 can be protected.

Further, as shown in FIGS. 1 and 2, in the crushing plant vehicle capable of traveling on the road, the drive source 8, the operation panel 9 and the like are arranged in a well-balanced manner in an appropriate space such as the rear portion of the vehicle body frame 4. ing. The transfer conveyor 10 is a bucket conveyor type, and in order to transfer the processing material, that is, the lump or crushed material discharged from the crusher 6 to the vibrating screener 7,
The discharge hopper 11 and the discharge chute 12 provided in the lower portion of the crusher 6 and the hopper 13 of the vibrating screener 7 are connected to the hopper 13 so as to extend in an inclined state that rises in the front direction of the vehicle. When the size of the crushed material crushed by the crusher 6 is larger than a predetermined size, the return conveyor 14 returns the crushed material to the crusher 6 again and crushes it.
The discharge portion 15 and the hopper 16 of the crusher 6 are connected to each other and extend in an inclined state that rises in the rearward direction of the vehicle. In the space on the vehicle body frame 4 close to the vibrating screener 7, in order to prevent scattering of dust generated when the object to be crushed is crushed by the crusher 6 or when the crushed product is sorted by the vibrating screener 7. Water tank 1 for storing water that is sprayed against dust
7 is provided.

Further, the ground clearance at the upper edge of the hopper 16 is set to a height that meets the safety standards when the vehicle travels on the road, similar to the retracted crane 80, and the maximum allowable processing capacity is set. Is set to get. Since the crushed material is thrown into the hopper 16 at the time of operation, the return conveyor 14 is in a state of being raised above the upper edge of the hopper 16 as shown by the chain double-dashed line, but the upper portion of the return conveyor 14 is higher than the upper edge of the hopper 16. Since the vehicle cannot travel on the road when it is at a high position, a cutout portion 18 is formed in the hopper 16 so that the upper portion of the return conveyor 14 is located below the upper edge of the hopper 16 when traveling on the road. Therefore, it is preferable to separately prepare a closing plate 18a having a size larger than the notch 18 that engages with the upper edge of the hopper 16 in order to close the notch 18 during operation of the crushing plant. In some cases, the hopper 16 may be removed from the crusher 6 and the upper portion of the return conveyor 14 may be lowered to meet the safety standards.

In this crushing plant vehicle capable of traveling on the road, the transfer conveyor 10 has a fixed frame portion 21, a group of rollers provided on the fixed frame portion 21, and a roller group, as shown in FIG. It is composed of the passed conveyor belt 20.

[0048]

The crushing plant vehicle capable of traveling on the road according to the present invention is constructed as described above and has the following effects. That is, this road-crushable crushing plant vehicle is composed of a tractor equipped with an engine and a trailer connected to and pulled by the tractor, and is related to a crusher and a crusher for crushing lumps on a vehicle body frame of the trailer. In the above-mentioned vibrating sieving machine, transfer conveyor, return conveyor, crushed material discharging means and crushable plant vehicle capable of traveling on the road where the drive device is installed, the crusher is grasped by the attachment attached to the tip to the crusher. Since the crane to be put in is installed at the rearmost part of the body frame,
Basically, when installing a crushing plant on a trailer, the vehicle width, vehicle height, and weight balance are taken into consideration so that the trailer can be driven on an ordinary road. As long as the road can be driven and the trailer can run, the crushing plant can be easily transported to the site where the material to be crushed is generated, and the waste material such as concrete and asphalt can be removed from the trailer while the crushing plant is installed. A crushing process can be performed. Moreover, the vehicle body frame is provided with a crane for loading the lumps into at least the crusher, and the lumps can be loaded into the crusher and processed over a wide range. Then, the granular material obtained by the crushing treatment can be recycled on site as a substitute for gravel, etc., and further, immediately after the processing of the lumps, it is not necessary to move to the next processing site and unload the crushing plant from the trailer again. The lumps can be immediately crushed again with the trailer set. Therefore,
When this crushing plant car that can run on the road goes to the site and crushes lumps, direct the dump truck that carries the crushed particulate matter to the crushing site and immediately load the particulate matter on the dump truck. When the granular material is used, for example, when it is used as a road surface base material, it can be transported to the road construction site.

When moving to a site where lumps such as concrete, asphalt, and waste materials are generated, the crane installed at the rearmost part of the body frame at the site where the lumps are generated is
It is possible to operate in a wide horizontal rotation range without being disturbed by other parts of the crushing plant car centering on the rearmost part, and a lump generated or accumulated within the range where the crane can reach within this operating range. In this case, the lump can be directly grasped and thrown into the crusher without newly setting the installation position of the trailer. Then, after the lumps are put into the crusher, the crushing plant vehicle can perform all the consistent processing for crushing. Further, the crusher, the vibrating screener, the transfer conveyor, the return conveyor and the crushed material discharging means, an engine installed on the body frame of a crushing plant car,
Since it is driven by the above-described drive device including a power source such as a hydraulic pressure generator or a generator and an operation panel, no external power source or the like is required. Further, since the attachment is attached to the tip of the crane, it is possible to deal with many kinds of lumps depending on the type of the attachment.

In addition, this crushable plant vehicle capable of traveling on the road has an air cushion and a leaf spring which are interposed between the rear wheel of the trailer and the vehicle body frame, which are in contact with the vehicle body frame, and the vehicle body frame. When equipped with a front outrigger provided at the front, a rear strut that can be grounded attached to the rear of the vehicle body frame, and a rear outrigger that supports the rearmost portion of the vehicle body frame in which the crane is installed, The impact force, vibration, etc. of the crusher are partly transmitted from the body frame to the rear wheels of the trailer via the air cushion and leaf springs, and partly supported on the front part of the body frame. Is supported on the ground, and the large impact force, vibration, etc. generated by the crusher is supported by the groundable rear support column attached to the rear part of the body frame. Since the rear part of the vehicle body frame on which the crane is installed is supported by the rear outrigger, the impact force of the crusher, the force such as vibration, and the load applied to the crane are eventually applied to the rear wheels of the trailer and both outriggers. Further, when the impact force, the vibration force or the like is larger than a predetermined value, they are dispersed and supported by the rear support. Also, the impact force,
Forces such as vibration and crane load do not concentrate on a specific location, especially the rear wheels, and impact forces, vibrations, and other forces transmitted from the vehicle body frame to the rear wheels of the trailer do not exceed a certain level. Further, since the rear wheels are transmitted through the air cushion and the leaf springs under a cushioning action, vibration and noise can be reduced as much as possible when crushing the lumps. Even in a town or the like, the crushing work can be performed in an environment within the noise regulation range without deteriorating the surrounding environment so much. Further, it is possible to prevent the rear wheels necessary for traveling on the road from being damaged due to the cushioning action.

When the crushing plant vehicle capable of traveling on the road is equipped with a conveyor for conveying the crushed material discharged from the crusher to the vibrating screener, the conveyor has a bottom portion. Because it is configured with a stretchable structure so that it can be raised to raise the ground clearance,
When operating a crushing plant, the bottom of the conveyor can be lowered to lower the ground clearance to a position where the crushed material discharged from the crusher can be received, and the crushed material can be transferred to the vibrating screener. At the same time, when the crushing plant is not in operation, by raising the bottom of the conveyor to raise the ground clearance, the crushing plant vehicle can be driven on the road.

Further, the crushing plant vehicle capable of running on the road is provided with a hopper for loading a lump provided at the upper part of the crusher,
In the case of having a conveyor inclination angle changing device for changing the inclination angle of the return conveyor, by operating the conveyor inclination angle changing device, when operating the crushing plant, the inclination angle of the return conveyor is increased. Then, a crushed product having a size larger than a predetermined size can be returned to the lump loading hopper by a return conveyor, and when the crushing plant is not in operation, the inclination angle of the return conveyor is lowered to increase the upper end of the return conveyor. Can also be lowered to the lower position by the lump charging hopper. Therefore, it is possible to return the crushed material of a predetermined size or more to the lump charging hopper by the return conveyor without unnecessarily lowering the height of the lump charging hopper and lowering the processing capacity of the plant. At the same time, the inclination angle of the return conveyor can be lowered to a size that satisfies the constraint required for road traveling, thereby enabling the plant vehicle to travel on road.

Further, this crushing plant vehicle capable of traveling on the road has a plurality of mounting fittings which are mounted on the outer wall surface in the longitudinal direction of the body frame at a distance from each other and L-shaped fittings which can be detachably mounted on the mounting fittings. However, in the case where the tiltable tilt plate provided on the vehicle body frame can be held in a horizontal state with the L-shaped fitting fitted to the fitting, and the tilt plate can be configured as a scaffold, A scaffolding as a space for employees to move around the crushing plant is secured, and handling, such as inspection, monitoring, and repair of the crushing plant is significantly improved.

In the crushing plant vehicle capable of traveling on the road, the crane includes an inner boom and an outer boom which at least one boom is extendable.
When traveling on the road, when the inner boom and the outer boom are folded within the width of the vehicle in the substantially width direction of the crushing plant vehicle, it is possible to expand the operating capacity of the crane by expanding and contracting the boom. Both booms can be folded almost in the width direction of the crushing plant vehicle when contracted to the maximum, so that the space occupied by the crane in the vehicle can be reduced not only in the vehicle width but also in the entire vehicle length direction, so that the vehicle can run on the road. Sometimes there is no hindrance. Therefore, the operating capacity of the crane can be obtained without unnecessarily reducing the size of the crane and reducing the ability to load lumps into the crusher, and it is large enough to meet the safety standards required for road traveling. In addition, the size of the crane can be reduced to enable the plant vehicle to travel on the road.

Further, in this crushing plant vehicle capable of traveling on the road, a grabble, a clamp, a hand, in which an attachment for grasping a lump is rotatably and detachably attached via a rotator at the tip of a crane,
When it is a magnet or bucket, the attachment can be removed to reduce the restrictions on transportation when there is no crane work such as traveling on the road. By selecting and attaching the attachment most suitable for, various works can be performed and workability can be improved.
