Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a self-propelled crusher, and more particularly, to an improved crushing efficiency of a crushed material capable of discharging a larger amount of crushed material. It belongs to the technical field of self-propelled crushers.

[0002]

2. Description of the Related Art In the past, a large amount of crushed material called concrete garbage, which is generated in road construction and demolition work of buildings, etc., was disposed of at waste disposal sites.
From the viewpoint of processing cost, in recent years, after being crushed so as to have a particle size equal to or smaller than a predetermined value, it is used as a lower roadbed material or a landfill material. Therefore, stationary crushers have been used for crushing construction waste materials in the past, but in recent years, self-propelled crushers that can perform crushing on the spot have come to be used. Such a self-propelled crusher has a configuration in which a hopper, a feeder, a crusher, and a conveyor for carrying out processing waste, which is a crushed material of construction waste material, are mounted on a traveling cart. The conveyor is designed to be short in terms of the wobble and the transportation posture of the trailer, etc., and the height from the ground to the tip of this conveyor is not so high, so a large amount of processing waste can not be deposited at a certain place. In the crushing process, a separate type secondary conveyor is used in combination to increase the height from the ground to the tip of the secondary conveyor.

However, the use of a secondary conveyor causes the following problems. A crane or the like is required for the installation of the secondary conveyor, and a driving source for driving the secondary conveyor is required, so that the cost required for the crushing operation increases. Since the secondary conveyor must be installed on flat ground, the mobility of the self-propelled crusher cannot be fully utilized. When the discharge amount of the processing waste increases and it accumulates near the front end side of the secondary conveyor, it is necessary to remove the accumulated processing waste using a hydraulic shovel or the like or to change the direction of the secondary conveyor. In such a case, it is necessary to temporarily stop the crushing operation, so that the efficiency of the crushing operation decreases.

By the way, in addition to a conveyor for receiving and transporting the processing waste discharged from the crusher, a secondary crusher which receives the processing waste from the conveyor and turns and can freely change the unloading position is provided on the traveling carriage. By doing so, a self-propelled crusher capable of solving the above-described problem has been proposed in, for example, Japanese Patent Application Laid-Open No. 9-122530. Hereinafter, a crusher, which is a self-propelled crusher according to this conventional example, will be described with reference to FIG. 4 of a side view thereof and FIG. This will be described.

A crusher 31 shown in FIG. 1 is a crusher which is a self-propelled crusher. The crusher 31 includes a lower traveling body 2, a base frame 3, a hopper 6, a crusher 9, and the like. The main body 4 is provided. Then, the construction waste material G, which is the material to be crushed, which has been put into the hopper 6, is fed to the crusher 9 by the feeder 7, and the processing waste G ', which is the crushed material crushed by the crusher 9, is taken out of the machine. A primary conveyor 32 and a secondary conveyor 42 are provided. This secondary conveyor 42 is the primary conveyor 32
The secondary conveyor 42 receives the processing waste G 'conveyed by the above and discharges it outside the machine.
A lower support bracket 36 provided on the distal end side of the primary conveyor 32 and an upper support bracket 37 located immediately above the lower support bracket 36 and disposed on the front side of the crusher body 4. Both ends are rotatably supported by supported shafts 38, and are configured to be able to turn (turn) right and left.

Therefore, according to the crushing machine 31 according to the conventional example, as can be clearly understood from FIG. 5, the crushing operation is not performed without using a crane or the like, and without temporarily stopping the crushing operation. By rotating the next conveyor 42 right and left, the crushed material transported by the primary conveyor 32 can be carried out to a plurality of locations, and a larger amount of crushed material,
For example, since building materials can be processed, the work efficiency of the crushing process of the crushed object can be improved, and the cost required for the crushing process can be reduced.

[0007] By the way, in the crushing process of the material to be crushed,
If the crusher 31 is moved by self-propelled movement, the crushed material can be discharged to a plurality of locations. Therefore, it is considered that there is no need to make the secondary conveyor 42 swivel. However, such a crusher 31 is usually large and heavy, and sinks little by little due to strong crushing vibration. Therefore, an iron plate or a sleeper is laid on the ground.
In order to change the discharge position of the crushed material, it is necessary to move an iron plate or a sleeper or the like laid, which is extremely troublesome.
Therefore, movement by self-propulsion is limited to a case where the processing site of the crushed material is changed. That is, such a crusher 31
When the crushing operation of the crushed object at a certain processing site is completed, the crushed object is transported to another processing site or a storage place by a trailer or the like.

[0008]

It is preferable that even a self-propelled crusher has a small number of parts to be disassembled during transportation.
However, the secondary conveyor of the crusher according to the above-mentioned conventional example is extremely long, so that the secondary conveyor itself needs to have high rigidity, and its support mechanism must also have high strength, so that the manufacturing cost increases. In addition, it is necessary to disassemble when transporting, and when it is carried into the work site, it is necessary to reassemble at the time of starting the crushing work, so that there is a problem to be solved that the preparation cost increases. Furthermore, in the self-propelled crusher, not only the crusher but also the primary conveyor and the secondary conveyor are operated by one power source, that is, one engine, so that a high-output engine is required. However, there is also a problem to be solved that the running cost of the crusher increases.

Accordingly, an object of the present invention is to discharge a large amount of crushed material out of the machine even if the conveyor for carrying the crushed material out of the machine is not so long, and with a small power. The goal is to provide a self-propelled crusher.

The conveyor 15 includes a conveyor frame 16 having a base end positioned below the crusher 9 and attached to a lower side of the base frame 3 and a tip end extending outside the self-propelled crusher 1. This conveyor frame 16
, A driving roller 17 rotatably driven by a hydraulic motor, a driven roller 18 rotatably provided at a base end of the conveyor frame 16, and a driving roller 17 and a driven roller 18. It comprises a transport belt 19 mounted thereon, and a plurality of guide rollers 16 a for supporting the upper and lower surface of the transport belt 19 and guiding the transport belt 19.

Further, a support frame 20, which is a support member having a tip protruding outward, is horizontally mounted on the upper front side of the base frame 3, and a chute 23 having a structure described later is pivoted to the tip of the support frame 20. A turning mechanism 21 for causing the rotation is provided. The rotating mechanism 21 includes a cylindrical casing 21 a fixed to the tip of the support frame 20.
The rotation of the rod of the hydraulic cylinder for rotation 21c, which is inserted into the casing 21a via a bearing (not shown) via a bearing (not shown) and whose bottom is pivotally attached to the lower surface of the support frame 20, causes a 180 ° range around the vertical axis. And a rotating rod 21b which can be continuously rotated in the inside and can be stopped at an arbitrary rotating position. A chute support device 22 having a configuration to be described later is attached by fitting a detachable connection pin 21d into a pin hole (not shown) provided at a lower end portion of the rotating rod 21b. The conveyor 1 is attached to the lower side of the support frame 20 and substantially at the center in the longitudinal direction.
5 is a magnetic separator 20a for sucking and removing magnetic materials such as reinforcing bars and iron chips mixed in the processing waste G ', and such a magnetic separator 20a is conventionally used. It is also provided in the crusher according to the example.

The chute support device 22 has a chute support frame 22a in which an upper end is connected to a rotating rod 21b by the connection pin 21d, and a chute 23 described later is swingably attached to a lower end of the chute support device 22. The chute 23 is pin-connected to the distal end side of the mounting portion with the chute support frame 22a, has a plurality of angle adjustment pin holes 22b 'on both sides in the width direction, and is connected to the chute support frame 22a by the angle adjustment pins 22c. The angle of the chute 23 which is interposed between the tilt angle adjusting arm 22b to be connected and the base end of the tilt angle adjusting arm 22b and the connecting pin 21d, and which is formed by the tilt angle adjusting arm 22b and the angle adjusting pin 22c. When adjusting
The tension coil springs 22d reduce the moment based on the weight of the chute 23 in order to reduce the labor. The side surface of the chute support frame 22a is curved, but may be straight, and the tension coil springs 22d, 22d need not necessarily be provided.

The chute 23 is composed of a gutter-shaped chute main body 23a and a low friction plate 23b attached to the side of the chute main body 23a on which the processing waste G 'slides, that is, on the inner surface. Further, a vibrator 24 that is hydraulically driven and applies a vibrating force to the chute 23 is provided on a lower surface on the base end side of the chute 23. The reason why such a vibrator 24 is provided is to increase the deposition height of the processing waste G 'by making the inclination angle of the chute 23 smaller, so that the direction of the chute 23 does not change. Also, more processing waste G 'can be discharged. In addition, as the low friction plate 23b, for example, a plate material made of an ultra-high molecular weight polyethylene resin which is used as a lining of an excavation bucket, a dump truck vessel, or the like and has excellent non-adhesion, abrasion resistance, and slidability can be used. .

Hereinafter, the self-propelled crusher 1 having the above configuration will be described.
First, before crushing the construction waste material G, the inclination angle adjusting arm 22b of the chute support device 22
Position adjustment and angle adjustment pin hole 2 of angle adjustment pin 22c '
The tilt angle of the chute 23 is adjusted by the insertion into 2b ', and the chute 23 is turned so as to be in a desired direction by the expansion and contraction of the rod of the hydraulic cylinder for rotation 21c. Next, the feeder 7, the crusher 9, and the conveyor 15 are operated, and the vibrator 24 is driven.
When the construction waste material G is put into the hopper 6 by a hydraulic shovel (not shown) or the like, the inputted construction waste material G is sequentially fed to the crusher 9 by the feeder 7 and crushed by the crusher 9. The processing waste G 'which is crushed and discharged from the crusher 9 is transported by the conveyor 15, and the processing waste G' continuously transported by the conveyor 15 slides down the chute 23 and is discharged outside the machine.

When the pile height of the processing waste G 'becomes approximately equal to the height of the tip of the chute 23 due to the continuation of the crushing operation of the building waste material G, the rotation of the rotating rod 21b due to the extension and contraction of the rod of the rotating hydraulic cylinder 21c is performed. Due to the rotation, the chute 23 is turned via the chute support device 22 and its direction is changed, so that the processing waste G 'can be continuously discharged to a new ground. In other words, a large amount of processing waste can be deposited by repeatedly changing the direction of the chute 23. Further, unlike the crusher according to the conventional example, a large amount of the conveyor 15 and the chute 23 that can be freely attached and detached by inserting and removing the connecting pin 21d without providing a longer secondary conveyor. Processing waste can be processed. Of course, the height of the pile of the processing waste G 'is lower than in the case of the crusher according to the conventional example.
However, since the chute 23 can be made larger than the turning angle of the long secondary conveyor of the crusher according to the conventional example, it is possible to deposit about the same amount of processing waste G 'as the conventional one.

As described above, according to the self-propelled crusher 1 according to the embodiment of the present invention, the conveyor 15 does not need to be long unlike the secondary conveyor of the crusher according to the conventional example. It is not necessary to make the 15 itself as rigid as a conventional secondary conveyor, and its support mechanism does not need to be so high in strength, which is advantageous in terms of manufacturing cost. As compared with the secondary conveyor of the conventional crusher, only the lighter chute 23 is required, and the chute 23 can be reassembled in a shorter time at the start of the crushing operation. Is more advantageous than before.

In the conventional crusher, it is necessary to drive not only the secondary conveyor but also the primary conveyor. On the other hand, in the self-propelled crusher 1 according to the embodiment of the present invention, the vibrator 24 is operated in addition to the conveyor 15;
In comparison of the driving energy between the primary conveyor and the vibrator 24, since the vibrator 24 can be driven with smaller energy, the running cost of the self-propelled crusher 1 is reduced in the case of the crusher according to the conventional example. Would be more advantageous.

In the above description, the vibrator 2
4 has been described as an example, but it is sufficient to make the inclination angle of the chute 23 slightly steep even without the vibrator 24, so that a reasonable effect can be expected. The sliding surface of the glass G 'is a low friction plate 23b.
However, even if such a low friction plate 23b is not stretched, a certain effect can be expected.

[0028]

As described in detail above, claim 1 of the present invention
According to the self-propelled crusher according to any one of (5) to (5), the crushed material is discharged to a plurality of locations by rotating the rotating member of the rotating mechanism supported by the supporting member provided on the traveling carriage to rotate the chute. According to the self-propelled crusher according to the second aspect, the crushing angle of the chute is reduced by the tilting angle changing function of the chute support device, so that more crushed material is discharged to one place. It is possible,
According to the self-propelled crusher according to the third aspect, the conveyor of the self-propelled crusher may be short, and the preparation cost can be reduced as compared with the conventional example in which the secondary conveyor is attached and detached. According to the self-propelled crusher according to 4,
According to the self-propelled crusher according to claim 5, the inclination angle of the chute can be further reduced by vibrating the chute by the vibrator. And a greater amount of crushed material can be deposited.

Therefore, according to the self-propelled crusher of the present invention, the conveyor does not need to be as long as the secondary conveyor of the crusher according to the conventional example, so that the conveyor itself can be used as the conventional secondary conveyor. In addition to the need for high rigidity, the support mechanism does not need to be so strong, which is advantageous in terms of manufacturing cost.In addition, if it is disassembled during transportation, only a lighter chute is required.
The preparation cost is also advantageous. Further, in the crusher according to the conventional example, while it is necessary to drive the primary conveyor in addition to the secondary conveyor, the vibrator is operated in addition to the conveyor. In the comparison of the driving energies, the exciter can be driven with smaller energy, so that the running cost of the self-propelled crusher is more advantageous than that of the conventional crusher.
