Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled crusher equipped with a crushing device for crushing crushed raw materials, and a self-propelled soil improver provided with a mixing device for adding a soil improving material to soil and crushing and mixing. The present invention relates to a device for predicting a trapping of emissions, which is provided in a self-propelled recycle product production machine including the above.

[0002]

2. Description of the Related Art In recent years, self-propelled crushers and self-propelled soil improvement machines have been developed under the background of promoting the reuse of waste such as the enforcement of the Recycling Resources Promotion Law (so-called Recycling Law) (October 1991). The place of activity of the traveling recyclables production machine is expanding.

[0003] Self-propelled crushers are used to construct various types of rocks, such as concrete lumps discharged at the time of building demolition and asphalt lumps discharged at the time of road repair, generated at construction sites.
Construction waste material or industrial waste (= crushed material) is used as a recycled material. For example, the recycled material (crushed material) input to a hopper as a receiving means above the self-propelled crusher by a hydraulic shovel or the like. ) Is guided to a crushing device as a processing device by, for example, a feeder provided below the hopper, and crushed to a predetermined size by the crushing device. The crushed material is dropped from a space below the crushing device onto a discharge conveyor arranged below the crushing device,
It is carried out by this discharge conveyor. During this unloading, a magnetic separator disposed above the discharge conveyor adsorbs and removes, for example, rebar pieces mixed in the concrete lump,
Crushed products (products or semi-finished products) for recycling are finally discharged outside the self-propelled crusher.

A self-propelled soil improvement machine is not suitable for backfilling of excavated soil (so-called construction soil) generated in, for example, burial work for gas pipes, water and sewage works, and other road works and foundation works. The recycle raw material (improvement target soil), which is put into a sediment hopper as a receiving means on the upper part of a self-propelled soil improvement machine by a hydraulic shovel or the like, for example, is provided below the sediment hopper by a hydraulic shovel or the like. The conveyer guides the mixture to a mixing device as a processing device. The mixing device performs a crushing and mixing process together with the soil improving material, and the mixture is dropped onto a discharge conveyor (conveying conveyor). (Product or semi-finished product) is finally discharged outside the self-propelled soil improvement machine.

As described above, in a self-propelled recycle product production machine, recycle products (crushed product, earth and sand product) are loaded below the discharge side end of the discharge conveyor as the production work progresses. At this time, the discharge conveyor usually includes a frame, a transport belt wound around a drive wheel and a driven wheel (idler) supported by the frame and driven by a hydraulic motor for the discharge conveyor, and a transfer belt. A supporting roller for supporting a conveying surface of the belt, and a guide roller for guiding the conveying belt from the side, and circulatingly driving the conveying belt (a feed belt portion moving in the conveying direction; And a moving return belt portion) to convey the recycled product. During the transport operation of the discharge conveyor, as described above, the recycled product having an increased loading height approaches or contacts the lower portion or the side portion of the discharge conveyor, moves on the return belt as it is, and moves the guide roller and the support. It may bite into rollers and the like.

Accordingly, Japanese Patent Laid-Open No. 7-18538 discloses a method for stopping the discharge conveyor in response to such an abnormal situation.
There is one described in JP-A-7. In this prior art, a self-propelled moving body is used, and a crushed object received by a hopper (hopper) is introduced into a crushing device (crushing machine) to perform crushing work and the crushed material is discharged by a discharge (belt) conveyor. A technology is disclosed in which a traveling crusher is provided with a pressure switch for detecting a load pressure of a discharge conveyor hydraulic motor, and the crushing device, the feeder, and the discharge conveyor are stopped according to the pressure detected by the pressure switch.

[0007]

However, the above-mentioned prior art has the following problems. That is, when the overload state is detected by the pressure switch, since the crushed material has already been caught, even if the discharge conveyor is stopped here, the work of removing the caught material must be performed manually. . This removal operation involves manually removing crushed materials that have been bitten by guide rollers and support rollers of the discharge conveyor one by one, and requires a great deal of time and labor. Therefore, it takes a long time to return to the crushing operation, and the operation efficiency is reduced, so that it is difficult to improve the productivity.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a self-propelled recycle product producing machine capable of improving productivity by detecting the bite of a recycled product in a discharge conveyor in advance and preventing the bite from occurring. It is an object of the present invention to provide a device for predicting a biting object.

[0009]

(1) In order to achieve the above object, the present invention introduces a recycled material received by a receiving means into a processing device, performs a predetermined process, and discharges the recycled material as a recycled product by a discharge conveyor. Detecting means provided in a self-propelled recycle product production machine for detecting the loading height of the recycle products discharged by the discharge conveyor, and command signal output means for outputting an output signal corresponding to the detection result of the detection means And

Recycled products discharged from the discharge conveyor are loaded, for example, on the ground from the discharge end of the discharge conveyor. Although the loading height increases with the progress of the processing operation, in the present invention, the loading height is detected by the detection means, and an output signal corresponding to the detection result is output by the command signal output means.

Thus, if it is detected, for example, that the loading height of the recycled products has approached the lower part of the discharge conveyor to some extent, a warning is issued to the operator by, for example, a warning means based on the output signal, and the operation is performed. The user manually operates the discharge conveyor to decelerate / stop the machine, scoop the loaded recycled product and put it into other equipment (another conveyor, etc.) so that the recycled product does not bite into the discharge conveyor. Some measures can be taken in advance.

Further, for example, by slowing down or stopping at least the processing device based on the output signal, it is possible to directly prevent or suppress the height of the recycle product from further increasing, whereby the recycle product is transferred to the discharge conveyor. It can also be prevented from biting.

Further, for example, based on the output signal, the prohibition releasing means releases the prohibition of the operation of the traveling means by the prohibiting means, thereby operating the traveling means and moving the self-propelled recycle product producing machine. It is also possible to create a new space below the discharge conveyor, so that the recycled product does not bite into the discharge conveyor.

Therefore, unlike the conventional structure for detecting an overload state due to the biting of the recycled product into the discharge conveyor or the like, the operation immediately returns to the production of the recycled product without performing the work of removing the bite of the once recycled product. As a result, operation efficiency can be improved and productivity can be improved.

(2) In the above (1), preferably,
A warning unit for issuing a warning to an operator according to an output signal of the command signal output unit;

(3) In the above (1), preferably, there is provided control means for decelerating or stopping at least the discharge conveyor in accordance with an output signal of the command signal output means.

(4) In the above (1), more preferably, the prohibition means for prohibiting the operation of the traveling means during the operation of the processing device, and the driving means of the traveling means in response to the output signal of the command signal output means. Prohibition canceling means for canceling the prohibition.

(5) In any one of the above (1) to (3), preferably, the detecting means includes a displacement member which comes into contact with the loaded recycled product and is displaced in accordance with the loading height. And the command signal output means outputs the output signal in accordance with the displacement of the displacement member.

(6) In any one of the above (1) to (5), preferably, the self-propelled recycle product production machine crushes the material to be crushed as the recycle raw material to produce the recycle product. A crushing device for producing crushed material is a self-propelled crusher provided as the processing device.

The crushed crushed material falls from the space below the crushing device 3 onto the discharge conveyor 6 and is conveyed, is almost uniform in size, and finally falls from the discharge side end of the discharge conveyor 6 to, for example, the ground. And loaded.

As the crushing operation is performed, the crushed material forms a mountain below the discharge side (right side in FIG. 1) end of the discharge conveyor 6, and the crushing operation (ie, the crushed material production operation) progresses. In addition, the height of this mountain is A as shown by a two-dot chain line in FIG.

The operator is notified that the pile of articles has reached a predetermined loading height. In the following, the operation and action of predicting (preliminary detection) of a trapped discharge will be described.

As described above, the crushed material dropped from the end of the discharge conveyor 6 on the discharge side (the right side in FIG. 1) is loaded under the crushed material, and the piles as shown by two-dot chain lines A to C in FIG. Make As the crushing work progresses and the loading height increases to B, the surface of the crushed material comes into contact with the plate member 24, and when the loading height further increases from B to C, the plate member 24 Is pushed by the surface of the mountain of crushed material and is displaced in the direction indicated by the arrow in FIG. At this time, since the rotating shaft 23a of the limit switch 23 and the plate member 24 are integrally connected by the connecting member 25 as described above, the rotating shaft 23a rotates with the rotation of the plate member 24, and the rotating shaft 23a When the angle is rotated (that is, when the loading height of the crushed material reaches a predetermined value and the plate member 24 is rotationally displaced by a predetermined amount), the limit switch 23 turns on its command signal to turn on the patrol light 22 (ie,
Warning display).

In the above description, the self-propelled crusher 1 constitutes the self-propelled recycle product producing machine described in the claims, the hopper 2 constitutes the receiving means, and the crusher (2)
The shaft shredder 3 constitutes a processing device, and the left and right crawler tracks 8 constitute traveling means.

As described above, in the above-described embodiment of the present invention, a warning signal is displayed to the operator with the patrol light 22 in response to the command signal from the limit switch 23, so that the operator can operate the control panel (not shown), for example. The crushed material bites into the discharge conveyor 6 such as manually decelerating or stopping the discharge conveyor 6 or scooping the crushed material loaded by a hydraulic shovel or the like and putting it into another device (another conveyor or the like). Some measures can be taken in advance so as not to be included.

Therefore, unlike the conventional structure for detecting an overload state due to the crushed material being caught in the discharge conveyor or the like, the guide roller 16b of the discharge conveyor 6 and the support roller 1
6a or the crushed material once caught by a driven roller or the like (not shown) can be immediately returned to the crushing operation without performing the operation of removing the crushed object, so that the operation efficiency can be improved and the productivity can be improved.

That is, when it is detected that the load height of the crushed material has approached to a lower portion of the return belt 15b of the discharge conveyor 6 to a certain extent, the crushing device 3 and the discharge conveyor 6 are stopped, so that the peak of the discharge is further increased. Can be directly prevented, thereby preventing the crushed material from being caught in the discharge conveyor 6.

Therefore, similar to the embodiment of the present invention,
Unlike the conventional structure, which detects an overload condition caused by the crushed material getting stuck in the discharge conveyor, the crushed material can be returned immediately to the crushing work without having to perform the work of removing the crushed material that has already been caught, thus improving operating efficiency. And productivity can be improved.

In the present embodiment, the crushing device 3 and the discharge conveyor 6 are stopped when the predetermined load height of the crushed material is detected by the limit switch 23. However, the present invention is not limited to this.

L and 10R (see FIG. 5) can be driven.

The control for turning off the control signal St among the functions of the solenoid control valve 50 and the controller 49 is a prohibiting means for prohibiting the operation of the traveling means during the operation of the processing apparatus described in the claims. The step 30A of the controller 49 constitutes a prohibition releasing means for releasing the prohibition of the traveling means in response to the output signal of the command signal output means.

In this modification, when the command signal of the limit switch 23 is turned on, the solenoid control valve 50 is switched as described above, and the left and right traveling hydraulic motors 10 are turned on.
Since the L and 10R can be driven, the operator operates the right and left traveling operation levers 38L and 38R to operate the traveling body 5 to move the self-propelled crusher 1 forward.
That is, by changing the place where the crushed material is loaded, a space below the discharge conveyor 6 is newly created, so that the crushed material can be prevented from biting into the discharge conveyor 6. At this time, the above-described step 30 is also performed, and
The crushing device 3 and the discharge conveyor 6 may be stopped to interrupt the crushing operation and the discharging operation.

Further, for example, the solenoid control valve 50 and the operating lever device 43 are connected through the above-described pilot introduction line 48a.
Pipes communicating with the pilot introduction pipes 44 and 46 are provided without passing through the L and 43R. An electromagnetic switching valve is disposed in these pipes. When a predetermined load height of the crushed material is detected by the limit switch 23, this electromagnetic The switching valve is switched by the controller 49 for a predetermined short time to guide the pilot pressure, and the left and right traveling control valves 34 and 35 are switched to the switching position 3.
4A and 35A may be switched so that the self-propelled crusher is slightly self-propelled forward. In these cases, a similar effect is obtained.
