2. Description of the Related Art In recent years, especially in cities, residential areas, urban areas, etc., demolishing and rebuilding of middle- and high-rise houses, buildings, structures, and the like have been actively performed, and redevelopment has been carried out. that time,
As a method of treating aggregates such as generated concrete and asphalt, waste materials such as buildings and structures, concrete,
The asphalt and other lump materials are crushed at the site where they are generated by a crusher, and the crushed materials are reused or recycled as road surface materials such as gravel, foundation materials such as buildings and structures, and backfill materials after excavation. The method of use has begun to take place. According to this method, it is possible to reduce the amount of dumping of the lump itself, and it is not necessary to find a landfill site and a dumping place of the lump and transport the lump over a long distance by a vehicle or the like. At the same time, the crushed material can be recycled and effectively used as a substitute for limited resources such as gravel, and can contribute to environmental protection and resource protection.

[0003] An installation-type crushing plant which is installed and used in a treatment plant as a crushing plant for crushing aggregates such as concrete, asphalt, waste materials, etc., basically has a crusher for crushing such aggregates mounted on a trailer. Then, the crusher is transported to a predetermined processing site, and the crusher is lowered from the trailer at the processing site for the lump, and assembled and arranged. In addition to the crusher, a vibrating sieve that sorts the crushed material, a driving device such as a generator, and a conveyor device such as a conveyor can be mounted on the trailer. Had to be placed.
Setting up the crushing plant in a different treatment plant from the place where such lumps are generated is a major task in transport and assembly work.
Not only does it require a lot of manpower, it also causes an increase in the cost of the crushing process, but it is also difficult to secure the crushing plant itself from the viewpoint of securing space and land prices. There is a problem in that the longer the distance from the place where the lump is generated, the more the transportation cost is required to transport the lump. In addition, even if a crushing plant can be built close to the place where the lump is generated, it is not preferable because noise and vibration are generated by the operation of the crushing plant, especially in urban areas and residential areas. Is not preferred.

[0004] On the other hand, a mobile crushing plant vehicle with wheels has also been developed, but it is intended to move only within a treatment plant. In order to travel on the road with a crushing plant installed, it is necessary to satisfy the restrictions on the width and height of vehicles according to the safety standards of the Road Transport Vehicle Act (hereinafter simply referred to as security standards), which is generally expected. In general, a mobile crushing plant vehicle having an agglomerated material processing capacity cannot run on a general road because of the regulations based on such security standards.

Accordingly, the applicant of the present invention has provided a crusher for crushing and reusing aggregates provided with a hopper for inputting aggregates such as waste materials such as buildings and structures, concrete and asphalt, etc. A vibrating sieve for sorting the crushed material, a conveyor for transferring the crushed material crushed by the crusher from the crusher to the vibrating sieve, and a crushed material of a predetermined size or more selected by the vibrating sieve. A crushing plant consisting of a return conveyor for feeding the crushing machine from the vibrating sieve to the crushing machine for re-crushing, and a driving device such as a generator for driving these devices is mounted on a trailer capable of traveling on a road so as to conform to safety standards. We have already proposed a crushing plant vehicle that can be installed on a road and that can run on the road so that noise and vibration can be reduced as much as possible even if the crushing plant is operated in an urban area or an urban area. Gantaira No. 5-71214 (JP-A-6
254429))].

According to the above crushing plant vehicle capable of traveling on the road, the crushing plant is installed on the trailer, the vehicle is driven on the road, and the trailer on which the crushing plant is installed is carried into the site where crushed materials such as concrete and asphalt are generated. In addition, the crushing process of the lump can be performed immediately with the crushing plant installed on the trailer, and the crushing process can be performed efficiently without taking much time for the work setup. There are advantages.

[Problems to be solved by the invention]

However, in a crushing plant vehicle capable of traveling on a road, the lump is put into the crushing machine, and the crushing machine is returned from the vibrating sieving machine to the smashing machine which is sent to the crushing machine by the return conveyor and crushed again. Regarding the input of crushed materials of a predetermined size or more, the mechanism for feeding the crushed material, that is, the lump to the crusher, is not complicated, and the area is large without preparing a dedicated input guide structure. If the space on the limited body frame can be used effectively,
More preferred.

[0008] In addition, the lump is not limited to a dry concrete lump, but may include a viscous substance that easily adheres to a smooth surface such as clayey material containing moisture. Even the crushed material of the above size contains moisture by nature, or it contains water when sprayed or sprayed to prevent dust scattering, and is a viscous material that easily adheres to smooth surfaces. There may be. In such a case, the viscous material adheres to the inner wall surface of the crusher and the wall surface of the hopper, and the subsequent lump and the crushed material having the predetermined size or more are prevented from being introduced into the crusher. There is.
Further, there is a possibility that the adhered viscous material may disturb the balance of the weight of the hopper and promote vibration of the hopper. Therefore, it is necessary to prevent such a viscous substance from adhering to the inner wall surface even if the lump or the crushed substance fed into the hopper of the crusher contains a viscous substance that easily adheres to the wall surface.

Also, the crushing process of the crusher inherently involves considerable vibration, and therefore the vibration of a hopper provided on the upper portion of the crusher is also considerable. On the other hand, since the return conveyor also vibrates but vibrates irrespective of the vibration of the hopper, the relative vibration between the hopper and the return conveyor increases, and the return conveyor is selected by the vibrating sieve and is fed by the return conveyor. The crushed material of the above size may not be put into a predetermined position of the hopper of the crusher. The crushed material discharged out of the hopper contaminates the body frame and surrounding environment of the crushing plant vehicle and threatens the safety of workers working on the body frame.
In addition, it may cause a failure of devices on the body frame. Therefore, the relative vibration between the hopper and the return conveyor is prevented, and even if it vibrates, both vibrate together, so that the crushed material of a predetermined size or more from the return conveyor is surely thrown into the hopper above the crusher. There is a need to.

[0010] Further, the crushed material having a size equal to or more than the predetermined size, which is put into the hopper from the discharge end of the return conveyor,
When the hopper is dropped, an impact may be applied to the hopper and the hopper may be deformed or damaged. Therefore, there is also a problem that it is necessary to reduce the impact and protect an original structure of the hopper.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and includes waste materials such as buildings and structures, concrete,
A crushing machine for crushing and reusing asphalt and other lumps, a vibrating sifter for sorting the crushed crushed material, a return conveyor, a conveyor, and a crushing machine including power generators for driving these devices The plant shall be installed on a trailer that can be run on the road so that it can meet safety standards. In addition, lumps and crushes of a predetermined size or more that are sent from the return conveyor to the crusher at the top of the crusher. A common charging structure should be provided for the crusher, and even if the lumps or crushed materials to be fed into the hopper of the crusher contain viscous materials that easily adhere to the smooth surface, It is necessary to prevent the sticky substance from adhering to the hopper and to prevent relative vibration between the hopper and the return conveyor to ensure that crushed material of a specified size or more from the return conveyor is fed into the hopper at the top of the crusher. Moreover, crushed return larger than the predetermined size to be introduced into the hopper from the carry-out end of the conveyor,
It is an object of the present invention to provide a crushing plant vehicle capable of traveling on a road, which can reduce the impact when falling to a hopper and protect the original structure of the hopper.

A conveyer for conveying to a sieving machine, a return conveyor for recirculating from the vibrating sieving machine to the crushing machine to re-crush the crushed material having a predetermined size or more selected by the vibrating sieving machine, and Comprises a crushed material discharge means for discharging the crushed material of a predetermined following sizes were screened with a sieve machine, the said crusher is provided lump turned hoppers, the vibrator is provided on the outer wall surface of the hopper A crushing plant vehicle capable of traveling on a road, provided with a vibration-prevention fitting for connecting a carry-out portion of the return conveyor and the hopper in order to prevent relative vibration between the hopper and the return conveyor.

A driving device for operating the crusher, the vibrating sieve, the conveyor and the return conveyor is provided on the vehicle body frame.

[0014] The anti-vibration fitting has a holding piece which is locked to an edge of the hopper and a holding piece which is locked to a frame of the return conveyor, and is connected to the hopper or the return conveyor.

This crushing plant vehicle capable of traveling on a road is capable of moving a hopper protection cover capable of covering an upper surface of a hopper corresponding to a position where the crushed material thrown into the hopper from the discharge end of the return conveyor falls. It is attached. Further, the hopper protective cover is movable to the upper surface of the hopper corresponding to the position where the crushed material falls when the return conveyor is operated, and moves to a position away from the upper surface of the hopper when the return conveyor is not operated. It is possible.

Further, the present invention provides an engine provided with a crusher for crushing a lump on a vehicle body frame supported on a tire via an air cushion and a leaf spring and near a rear wheel of the tire. A crushing plant vehicle that is mounted on a road and is capable of traveling on a road, a vibrating sieving machine installed at a front portion on the vehicle body frame and crushing the lumps by the crushing machine, and the crushing machine crushed by the crushing machine. It is installed on the vehicle body frame to convey an object from the crusher to the vibrating sieve machine, and extends upward from a discharge chute at a lower portion of the crusher to a hopper of the vibrating sieve machine and directly extends in one direction. A conveyor, installed on the vehicle body frame for re-crushing the crushed material having a size equal to or greater than a predetermined size selected by the vibrating sieve, and crushing the crushed material from a discharge part of the vibrating sieve; A return conveyor which inclines upward to a lump hopper for directly entering the lump and extends directly in one direction, a crushed material discharging means for discharging the crushed material having a size equal to or less than a predetermined size selected by the vibrating sieve, and a crusher.

A crushing plant vehicle capable of traveling on a road, wherein the crushed material discharging means is driven, and at least an impact force and a vibration generated by the crushing machine are buffered by the air cushion, the leaf spring, and the tire.

A driving device for operating the crushing machine, the vibrating sieving machine, the conveyor and the return conveyor is installed on the body frame, and the vibrator is provided outside the crusher. It is provided on the wall.

Since the crushing plant vehicle capable of traveling on the road is configured as described above, when the lump is put into the crusher, the lump is put into the hopper, and the lump is removed from the crusher. When the crushed product reaches the crusher via the hopper and the crushed material having the predetermined size or more from the return conveyor is sent to the crusher, the crushed material is charged from the return conveyor into the hopper, and the hopper is removed. Through the crusher. In particular, since the crushing plant vehicle capable of traveling on the road is equipped with a vibrator on the crusher wall and the hopper wall of the crusher, it can be used to remove lumps or crushed materials of a predetermined size or more selected by a vibrating screen. When a clay or other viscous material containing water that easily adheres to a smooth surface such as the inner wall surface, the viscous material put into the hopper of the crusher makes the smooth surface of the plate material that composes the crusher. The viscous material attached to the crusher vibrates the crusher even if it collides with or adheres to the crusher, so the viscous material is dropped into the crusher without adhering to the crusher. . Therefore, the weight distribution of the crusher does not collapse due to the adhered viscous material.
The vibration of the crusher is not promoted.

This crushing plant vehicle capable of traveling on a road is provided with a vibration-prevention fitting for connecting the discharge end of the return conveyor and the hopper to prevent relative vibration between the hopper and the return conveyor. Therefore, the vibration of the hopper provided at the top of the crusher and the return conveyor cannot vibrate independently of each other. This is particularly effective when a vibrator is attached to the hopper to prevent the viscous material from adhering to the hopper. Since the relative vibration between the hopper and the return conveyor is suppressed by the metal fittings, the crushed material of a predetermined size or more, which is circulated by the return conveyor, is always thrown into a predetermined place of the hopper of the crusher and dropped into the crusher. Will be.

In the crushing plant vehicle capable of traveling on the road, a hopper protection cover for covering the hopper is provided at a portion of the structural portion of the hopper which is located immediately below the discharge end of the return conveyor. When the return conveyor is operated and the crushed material having the size equal to or larger than the predetermined size selected by the vibrating sieve is sent to the crusher to be crushed again, the hopper protection cover is returned to the return conveyor. Is moved to the position just below the discharge end, and is fixed to the hopper at that position. At this time, the crushed material having the predetermined size or more collides with the hopper protection cover when dropped into the hopper from the unloading end of the return conveyor, and does not directly impact the hopper. Reduces shock. On the other hand, when the return conveyor is in operation, even if the discharge end is at a height that does not meet the safety standards, when the return conveyor is not operating, such as when a crushing plant vehicle is traveling on a road, the hopper protection cover is used for the return conveyor. Since it can be removed from directly below the discharge end, the height of the discharge end of the return conveyor can be reduced to a height that satisfies security standards without any problem.

The ground height at the upper edge of the hopper 16 of the crusher 6 is set to a height that conforms to safety standards when the vehicle travels on the road, and is set so as to obtain the maximum allowable processing capacity. Have been. When the return conveyor 14 is operated, the crushed material is put into the hopper 16 so that the return conveyor 14 rises from the upper edge of the hopper 16 as shown by a two-dot chain line. At a high position, the vehicle cannot travel on the road. Therefore, the notch 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.
Is formed. Therefore, during the operation of the crushing plant, as shown in FIG.
It is preferable to separately prepare a closing plate 18a having a size larger than the notch 18 provided with the hook 19 that engages with the upper edge of the hopper 16. In some cases, the hopper 16 may be detached from the crusher 6 and the upper portion of the return conveyor 14 may be lowered to meet security standards.

The crushing plant vehicle capable of traveling on the road is basically the invention according to the prior application by the present applicant (Japanese Patent Laid-Open No. 6-2).
No. 54429).

Agglomerates such as concrete, asphalt, waste materials, and the like are transferred to the hopper 16 by using a dedicated gripping means other than the crushing plant vehicle or by using a gripping device (not shown) mounted on the crushing plant vehicle. It is charged and then dropped into the crusher 6.

Although the side plate of the hopper 16 provided with 00 is shown as the side plate 204 due to space restrictions, the present invention is not limited to this side plate. Further, the sheet metal structure of the hopper 16 is not limited to the above example. The outer plate 209 of the impact crusher, which is the crusher 6, can be provided with a vibrator 200 having the same structure in the same manner for the same reason as in the case of the hopper 16.

At the site where the crushing process is to be performed, the lump is directly introduced into the crusher 6 by a gripping means such as a crane, and the crushed material having a size equal to or larger than a predetermined size sent from the return conveyor 14 to the crusher 6. When dropped into the crusher 6 from the discharge end of the return conveyor 14, viscous substances that may be included in the lumps or crushed substances are removed from the outside 20 of the hopper 16.

That is, a type in which the return conveyor 14 is disposed on the right side in the traveling direction of the vehicle is shown. Of course, these layouts
The position can be set according to the position and type of the crusher and the vibrating sieve. 7 and 8 show the return conveyor 14.
Bracket 21 against discharge end 220 of hopper 16 and hopper 16.
It is a figure showing the state where 0 was used. Anti-vibration bracket 210
Has, for example, a substantially L-shaped main body 211 obtained by bending a narrow metal plate, and an engaging portion 212 that can be engaged with an edge 208 of the side plate 206 of the hopper 16 at each end of the main body 211. And an engaging portion 213 that can engage with the frame 221 located at the discharge end 220 of the return conveyor 14. The edge 208 is bent, for example, from the side plate 206 in the conveying direction of the return conveyor 14, but may be the edge of any of the side plates 204, 205, 206, and 207. May be the edge of
In some cases, the side plates 204, 205, 206, 207
It goes without saying that the bracket provided in the above may be used. The engagement portion 212 includes one end of the main body 211 and a holding piece 214, and is engaged by sandwiching the upper edge of the edge 208 of the side plate 206. The engaging portion 213 includes the other end of the main body 211 and the holding piece 215, and engages by sandwiching the frame 221 integrated with one of the left and right frames 83 extending to the discharge end 220 of the return conveyor 14. .

When the return conveyor 14 and the hopper 16 are in a predetermined positional relationship when the crushed material having a predetermined size or more is sent to the crusher 6, the two engaging portions 21
2 and 213 are a hopper 16 and a return conveyor 14 respectively.
And engage. The chain 216 has one end 217 fixed to the upper edge of the side plate 206 of the hopper 16 and the other end 218 fixed to the anti-vibration bracket 210. In order to reduce the height of the return conveyor 14 so that it can travel on the road, the return conveyor 14
Although it is necessary to release the connection between the hopper 16 and the hopper 16, even if both the engaging portions 212 and 213 of the buckle 210 are detached from the hopper 16 and the return conveyor 14, the buckle 210 is attached to the hopper 16 by the chain 216. It will not be lost in the suspended state.

The crushing capacity of the crusher 6 is such that it can perform a process of crushing a concrete lump or the like and involves considerable vibration. Therefore, the vibration of the hopper 16 provided on the upper part of the crusher 6 becomes considerable. Further, a vibrator 200 is provided on the side plate of the hopper 16 in order to prevent sticking of a lump or a viscous substance that may be contained in the crushed substance from the return conveyor 14. The vibration of 16 may be greater. On the other hand, the return conveyor 14 may also vibrate, and the return conveyor 14 vibrates independently of the vibration of the hopper 16, so that the relative vibration between the hopper 16 and the return conveyor 14 may be further increased. For this reason, even if the crushed material having a size equal to or larger than a predetermined size selected by the vibrating sieve 7 is sent back by the return conveyor 14, the crushed material may not be correctly input to the hopper 16 of the crusher 6. If the crushed material overflows out of the hopper 16, the crushed plant vehicle and the surrounding environment on the body frame 4 of the crushing plant vehicle may be polluted.
This will threaten the safety of the workers working on the above, and may also cause the equipment on the body frame 4 to fail. Since the anti-vibration fitting 210 prevents relative vibration between the hopper 16 and the return conveyor 14, the crushed material having a size equal to or larger than a predetermined size from the return conveyor 14 is reliably fed into the hopper 16 provided on the top of the crusher 6. Will be.

FIGS. 9 and 10 show a hopper protection cover 230 attached to a portion of the structural portion of the hopper 16 which is located immediately below the discharge end 220 of the return conveyor 14, and FIGS. 8 is a type in which the layout of the return conveyor in the crushing plant vehicle is the type shown in FIGS. 1 to 3 in which the left and right are reversed, that is, the type in which the return conveyor 14 is arranged on the right side in the traveling direction of the vehicle. FIG. 9 is a diagram illustrating a state in which a protective cover 230 is used. In the embodiment shown in FIG.
4, the discharge end 22 of the return conveyor 14
From the hopper 16 of the crusher 6 where
a is removed, and the discharge end 220 is located above the hopper 16 through a part of the removed and opened space. The crushed material having a size equal to or larger than a predetermined size selected by the vibrating sieve 7 falls from the discharge end 220 of the return conveyor 14 and is thrown into the hopper 16. At this time, the impact of the crushed material on the hopper 16 is reduced. For this purpose, a hopper protection cover 230 is provided so as to be able to move forward and backward with respect to the area of the hopper which collides when dropped. That is, the hopper protection cover 2
30 includes a slope portion 231 and a vertical surface portion 232 bent downward from the upper edge of the slope portion 231. The slope portion 231 is substantially parallel to the slope portion 234 of the side plate 207, and the vertical surface portion 232 is parallel to the vertical surface portion 235 of the side plate 207.

The hopper protective cover 230 collides with the side plate 207 of the hopper 16 when the crushed material having a predetermined size or more in the slope portion 231 of the side plate 207 falls from the discharge end 220 of the return conveyor 14. The vertical surface portion 23 of the side plate
2 is detachably fixed by bolts 233 and 233. The hopper protection cover 230 is provided so as to be able to advance and retreat along the side plate 207 in the direction indicated by the arrow Z in FIG.
When the return conveyor 14 is not operated, the return conveyor 14 may be retracted from the discharge end 220 and similarly attached with a bolt at another position on the side plate 207. Further, the body frame 4 is not limited to the side plate 207.
You may keep it in another place above. The crusher 6
Although the example in which the hopper protection cover 230 is provided in a state in which the closing plate 18a is removed from the hopper 16 has been described, the hopper protection cover 230 is closed so that the crushed material sent to the crusher 6 is not dropped. The plate 18a also functions. However, the present invention is not limited to this, and the hopper protection cover 230 may be attached so as to partially or entirely overlap the closure plate 18a while the closure plate 18a is attached, thereby protecting the closure plate 18a.

The crushed material having a size equal to or greater than a predetermined size selected by the vibrating sieve 7 falls into the hopper 16 and directly collides with the side plate of the hopper 16 when being thrown into the hopper 16 from the discharge end 220 of the return conveyor 14. , The hopper 16 may be deformed or damaged. However, the hopper protection cover 23 is located immediately below the discharge end 220 of the return conveyor 14.
As the crushed material having a size equal to or larger than the predetermined value falls from the discharge end 220, the crushed material once collides with the hopper protection cover 230 and does not directly collide with the side plate of the hopper 16. Therefore, the impact is not directly applied to the hopper 16, and the impact on the hopper is reduced. on the other hand,
When the return conveyor 14 is not operated, for example, when the crushing plant vehicle travels on the road, the hopper protection cover 230
Is moved out of the return conveyor 14 immediately below the discharge end 220 to another location, so that the discharge end 220 of the return conveyor 14 can be stored in the notch 18. That is,
When the return conveyor 14 is in operation, the height position of the discharge end 220 is higher than the height of the hopper 16 so that the safety standards are not satisfied.
30 can be removed to lower the height of the return conveyor 14 to meet security standards.

The details of the conveyor 10, the vibrating sieve 7, the return conveyor 14, and the like in the plant vehicle capable of traveling on the road can be configured in the same manner as the invention disclosed in the above-mentioned prior application by the present applicant. The details will be described below. By moving the movable frame portion 23 upward with respect to the fixed frame portion 21, the transport conveyor 10 is configured to be capable of contracting and moving in the longitudinal direction. The roller shaft 24 and the tail belt roller 27 arranged at the lower part of the conveyor 10, that is, at the lower end of the conveyor 10, are moved upward, so that the crushing plant vehicle capable of traveling on the road travels on the road at the minimum specified in the safety standards. Ground clearance is secured. Even if the conveyor belt 20 is slightly slackened, it will not be impossible to run by colliding with an obstacle on the road. In some cases, the conveyor belt 20 may be suspended by a rope or the like when the crushing plant vehicle travels.

As shown in FIG. 11, an operating mechanism 33 for extending and retracting the conveyor 10 comprises a pair of bevel gears 36, 37,
It is composed of a handle 34, a ball screw 31, a screw rod 32 and the like. The moving frame portion 23 includes a roller shaft 24 on which the tail belt roller 27 is loosely fitted, a pair of moving frames 23a, 23a, and a horizontal frame 25. Two holding rods 3 bridged between the moving frames 23a, 23a
A sliding cylinder having a female screw, that is, a ball screw 31 is sandwiched between 0 and 30. The fixed frame 2 has a U-shaped cross section.
1a and 21a are slidably fitted. Fixed frame 2

The holding rod 30 is fixed in the longitudinal direction.

By operating the operating mechanism 33, the conveyor 10
In order to expand and contract, the screw rod 32 is rotated through the bevel gears 36 and 37 by rotating the handle 34. The rotation of the screw rod 32 causes the ball screw 31 to move on the screw rod 32, and causes the moving frame 23 to move on the fixed frame 21 as indicated by the arrow S through the holding rod 30. When the moving frame 23 moves, the tail belt roller 27 attached to the moving frame 23 moves, whereby the conveyor 10 can expand and contract. The mechanism for expanding and contracting the transport conveyor 10 may use an operating mechanism such as a hydraulic cylinder mechanism instead of the mechanical mechanism described above. By connecting the cylinder and the piston rod of the hydraulic cylinder mechanism directly to the moving frame portion and the fixed frame portion, respectively, both frames can be expanded and contracted.

As shown in FIG. 12, the vibration sieving machine 7 is provided with a vibration damping member (not shown) made of rubber or the like.
A frame 39 is attached to the leg 38, and a sieve 40 provided via a spring or the like is attached to the frame 39. The crushed material sent from the conveyor 10 is supplied to the sieve 40 through the hopper 13. The sieve 40 is a hopper 13
The discharge port 15 is formed at a lower end of the lower end of the vehicle, which is installed so that the inlet side of the vehicle is higher and inclined downward in the width direction of the vehicle. Accordingly, the crushed material is sorted by the sieve 40 as the vibration proceeds from the high area of the sieve 40 to the discharge part 15 on the lower side, and
The crushed material crushed to a predetermined size or less passes through the sieve 40 and falls, and the crushed material larger than a predetermined size proceeds to the discharge unit 15 of the sieve 40. The crushed material that has dropped after passing through the sieve 40 falls through the hopper 41 to the unloading conveyor 54, is unloaded to the unloading chute 75 by the unloading conveyor 54, and is then unloaded to a predetermined location by the conveyor 76 provided outside the crushing plant vehicle. You.

The carry-out conveyor 54 can slide in the width direction of the vehicle body frame 4. When discharging the crushed material from the vibrating sieve 7, as shown by an arrow U in FIG. 12, the conveyor 54 is slid so that one side protrudes outside the body frame 4, and one side is connected to the discharge chute 75. And the crushed material can be discharged. The unloading chute 75 attached to the outside of the body frame 4 is removed when the vehicle is running.

It is pivotally connected via 5,45. Each fixed rod 48 is connected by a crossbar 80,
0 is provided with a lifting mechanism 44. The lifting mechanism 44 includes a rotating shaft 50 rotatably mounted on a bracket 81 provided on a cross bar 80 and rotatable by a handle 49, a bevel gear 51 fixed to an end of the rotating shaft 50 so as to be integrally rotatable, A bevel gear 52 that meshes with the bevel gear 51 and a screw rod 53 that moves up and down through the bevel gear 52 are provided. A bevel gear 52 having a female screw 82 formed at the shaft center is rotatably attached to the crossbar 80. Further, an elevating screw rod 53 fixed to a horizontal rod 47 fixing the elevating rod is screwed to the bevel gear 52.

Since the conveyor inclination changing device 42 has the above configuration, when the handle 49 is rotated, the rotating shaft 50 is rotated.
Then, the bevel gear 51 rotates, and then the bevel gear 52 meshing with the bevel gear 51 rotates. The rotation of the bevel gear 52 moves the lifting screw 53 in the vertical direction. When the lifting screw 53 moves up and down, as shown by arrow V in FIG. 13, the lifting rod 46 moves up and down with respect to the fixed rod 48, and therefore, the inclination angle of the return conveyor 14 is changed, and the return conveyor 14 is changed. The height of the upper part of the can be reduced. As a mechanism for changing the inclination of the return conveyor 14, an operating mechanism such as a hydraulic cylinder mechanism may be used instead of the mechanical mechanism described above. The cylinder of the hydraulic cylinder mechanism and the piston rod are respectively connected to the body frame 4 and the left and right frames 83, 8 of the return conveyor 14.
3 can be connected directly to change the inclination of the return conveyor 14.

Further, the crushing plant vehicle capable of traveling on the road has a structure in which the doors at least on both sides of the peripheral edge of the body frame 4, that is, the tilt plate 60 can be used as a work scaffold as shown in FIG. I have. A plurality of mounting brackets 61 such as U-shaped non-circular metal brackets as viewed in a horizontal cross section are attached to a plurality of mounting brackets 61 spaced apart from each other in the longitudinal direction outer wall surface of the vehicle body frame 4.

The tilt plate 60 can be used as a scaffold.
As shown in FIG. 15, the combination of the L-shaped fitting and the mounting fitting is the same as that shown in FIG.
The mounting bracket 61a may be the same as the mounting bracket 61 except that the same L-shaped bracket 62a and the slit 64 for the rib are formed. Further, a lateral hole (not shown) may be formed in the body frame 4 around the loading platform, and a bar-like support (not shown) may be fitted into the lateral hole to support the tilt plate 60 horizontally. . As described above, when forming a scaffold at the crushing work site, necessary L-shaped fittings are separately provided on the body frame 4.
To run on the road,
Since the dimensions of the metal fittings are not taken into account, the width of the vehicle can be sufficiently secured while satisfying security standards.

The crushing plant vehicle capable of traveling on the road has been described in the above embodiment with respect to the operating mechanism 33 for expanding and contracting the transport conveyor 10 and the elevating mechanism 44 of the return conveyor 14. Is
The present invention is not limited to the above embodiment, and can be configured using a device such as a winch. In the above embodiment, the height of the tail belt roller 27 of the conveyor 10 from the ground is set to the minimum ground clearance specified in the security standards.
Although the lower portion of the transport conveyor 10 is configured to expand and contract in the longitudinal direction, the entire transport conveyor 10 may be slid in the longitudinal direction of the transport conveyor 10. Depending on the size of the vibrating sieve 7, the upper end of the conveyor 10 may exceed the height specified in the security standards. In this case, the upper part of the conveyor 10 may be divided and folded. Good.
This means can also be used for height control of the return conveyor 14. The dividing technology of the conveyor 10 can also be used as a measure for lifting the lower part of the conveyor 10.

Can be prevented from adhering to the inside of the. In addition, a vibration damper 210 provided between the return conveyor 14 and the hopper 16 of the crusher 6 also connects between the transport conveyor 10 and the hopper 13 of the vibrating sieve 7 in a similar situation. May be used. Further, the hopper protection cover 230 may be provided on the hopper 13 of the vibrating sieve 7 in the same manner as provided on the hopper 16 of the crusher 6.

[0050]

Since the crushing plant vehicle capable of traveling on the road according to the present invention is constructed as described above, when the lump is put into the crusher, the lump is put into the hopper. The crusher is reached via the hopper,
Even when the crushed material having the predetermined size or more from the return conveyor is sent to the crusher, the crushed material is put into the hopper from the return conveyor and sent to the crusher via the hopper. Therefore, it is not necessary to provide a dedicated charging guide structure for the lump and the crushed material of the predetermined size or more from the return conveyor, and the mechanism for charging the crushed material to the crusher is unnecessary. It is simplified and the limited space on the body frame is effectively used.

When the crushing plant vehicle capable of traveling on the road is one in which a vibrator is attached to the hopper, a crushed material having a predetermined size or more selected by a lump or a vibrating sieve is added to a metal plate. When a viscous material such as clay containing water that easily adheres to the smooth surface of the hopper, the viscous material collides with or adheres to the smooth surface of the plate material that composes the hopper. However, since the vibrator attached to the hopper vibrates the hopper, the viscous material is dropped into the crusher without adhering to the hopper for a long time. Therefore, because of the viscous material adhering to the hopper, the introduction of a new lump or a crushed material of a predetermined size or more selected by the vibrating sieve into the crusher is not hindered.
A situation in which the crushing process is stopped halfway and a cleaning operation for removing a viscous substance attached to the hopper is avoided, and the crushing process can be performed continuously and efficiently.

The crushing plant vehicle capable of traveling on the road is provided with a vibration-prevention fitting for connecting the discharge end of the return conveyor and the hopper to prevent relative vibration between the hopper and the return conveyor. In some cases, the vibration of the hopper provided above the crusher and the return conveyor cannot vibrate independently of each other. This means that
It is also particularly effective when a vibrator is attached to the hopper to prevent the viscous material from adhering to the hopper. Since the relative vibration between the hopper and the return conveyor is suppressed by the metal fittings, the crushed material of a predetermined size or more sent by the return conveyor is correctly put into the hopper of the crusher and dropped into the crusher. . Therefore, the crushed material having a size larger than a predetermined size, which is forwarded by the return conveyor,
Dropped outside the hopper of the crusher, polluting the body frame of the crushing plant vehicle, the equipment related to the crusher or the surrounding environment, and threatening the safety of workers working on the body frame. And no cause is caused for the failure of the related equipment on the body frame.

Further, the crushing plant vehicle capable of traveling on the road is provided in a portion of the structural portion of the hopper which is located immediately below the discharge end of the return conveyor for feeding the crushed material having the predetermined size or more to the crusher. If the hopper protection cover for covering the portion is detachably provided, the return conveyor is operated, and the crushed material having the size equal to or larger than the predetermined size selected by the vibrating sieve is sent to the crusher, and the crushed material is returned to the crusher again. When crushing is to be performed, the hopper protection cover is placed so as to cover the hopper portion located immediately below the discharge end of the return conveyor, and is fixed to the hopper at that position. At this time, the crushed material having the predetermined size or more collides with the hopper protection cover when dropped into the hopper from the unloading end of the return conveyor, and does not directly impact the hopper. Reduces shock. Therefore, the hopper does not suffer the deformation and damage due to the impact, and can maintain the function of the hopper for a long time. On the other hand, even if the unloading end is at a height that does not meet security standards when the return conveyor is operating, the hopper protection cover is removed from the hopper when the return conveyor is not operating, such as when the crushing plant vehicle is traveling on the road. As a result, the height of the discharge end of the return conveyor can be reduced to a height that satisfies security standards without any problem.
