Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled soil improvement machine, a soil improvement system, and a soil improvement method for receiving soil and supplying and improving soil improvement material.

[0002]

2. Description of the Related Art In recent years, under the background of the promotion of waste recycling, such as the enforcement of the so-called Recycling Law (October 1991),
For example, excavated soil (so-called construction-generated soil) generated in burial work such as gas pipes, water and sewage works, and other road works and foundation works is stirred and mixed with soil improvement materials to obtain improved soil for recycling. The need for self-propelled soil improvement machines is expanding.

[0003] As such a self-propelled soil improvement machine, for example, as described in JP-A-2000-45327,
A soil improvement material is supplied from a soil improvement material storage hopper (soil improvement material hopper) to a soil which is put into a hopper (earth and sand hopper) and conveyed by a conveyance conveyor (import conveyor), and a mixture of the soil and the soil improvement material. Is stirred and mixed by a mixing device (processing tank) internally provided with a stirring means (paddle mixer) provided with a plurality of stirring blades (paddles) to produce improved soil, and the improved soil is discharged by a discharge conveyor (discharge unit). Has already been proposed.

In this prior art, each of the above-described mechanisms constituting the soil improvement function component is provided in a main body frame, and a traveling body is fixedly attached to a lower portion of the main body frame to enable self-traveling.

[0005]

However, the above prior art has the following problems. That is, in the background of the above-mentioned promotion of waste recycling, there are many cases where many types of earth and sand are to be reformed at the same site. For example, usually, sandy soil, which is relatively easy to modify, is separated from soil that hardly increases in CBR value even when cured at a high water content (for example, Kanto loam or Ariake clay). It is desirable to accumulate in different places, and to separate and distribute the improved soil that has been modified.

[0006] As described above, when changing the accumulation position of the improved soil, the main body frame supporting each mechanism constituting the soil improvement function component and the traveling body are fixedly connected as in the prior art. In the self-propelled soil improvement machine, the traveling body is driven and controlled so that the discharge position of the improved soil (that is, the end position of the discharge conveyor on the downstream side in the transport direction) is at a desired position. The position of the soil improvement machine itself had to be finely controlled. At this time, the receiving side (that is, the above-mentioned hopper side) is considered in consideration of the workability of the earth and sand input.
You may also need to adjust the position of
At the operation site of the self-propelled soil improvement machine, there is not always a sufficient working space.Therefore, the fine movement control of the position of the self-propelled soil improvement machine itself by the drive control of the traveling body as described above The work was very cumbersome.

In the self-propelled soil improvement machine of the present invention having the above-described structure, the most significant feature of the present embodiment is that the soil improvement function component 4 for mixing and discharging the soil to be reformed with the soil improvement material is: It is provided so as to be able to turn with respect to the traveling body 1.

Here, FIG. 4 is a sectional view showing a detailed structure of a turning device provided in an embodiment of the self-propelled soil conditioner of the present invention. In FIG. 4, reference numeral 46 denotes a turning frame fixed to the lower frame 15 by, for example, welding or the like. On this turning frame 46, a turning motor 47 is fixed by a bolt 49 via a support base 48 (that is, in other words, the turning frame is fixed). The turning motor 47 is provided on the soil improvement function component 4 side). The slewing motor 47 is strictly composed of an upper drive unit 50 and a speed reduction mechanism unit 51 connected to a lower part of the drive unit 50. The rotation is performed by a reduction gear mechanism such as, for example, a planetary gear mechanism provided in the reduction mechanism section 51 with respect to the pinion 52 fixed to the tip of the output shaft (not shown) of the (rotation motor 47) projecting downward.

It is designed to rotate. With such a structure, the lower frame 15 turns with respect to the truck frame 5 (in other words, the soil improvement function constituting unit 4 with respect to the traveling body 1).

At this time, the swing motor 47 (strictly, the drive unit 50) is constituted by, for example, a hydraulic motor,
It is connected to the hydraulic pump (not shown) provided in the power unit 43 via a turning control valve (not shown). The turning control valve (not shown) also constitutes the control valve device (not shown) provided in the power unit 43, for example, and is switched by an operation panel (not shown) provided in the driver's seat 44, for example.

Next, the basic operation of one embodiment of the self-propelled soil conditioner of the present invention will be described. For example, when earth and sand are charged into the sieve device 9 of the self-propelled soil improvement machine by a bucket or the like of a hydraulic excavator 200 (see FIG. 7 described later), the sediment component passing through the grid 20 of the sieve device 9 is transferred to the lower hopper 10. Is introduced. The earth and sand received by the hopper 10 is placed on the conveyor belt 25 of the conveyor 12 below the earth and conveyed to the other of the self-propelled soil improvement machine. Then, near the downstream end of the conveyor 12 in the conveying direction, a predetermined amount of soil improving material is added from the soil improving material storage hopper 13 via the feeder 32 to the surface of the conveyed earth and sand. 12 introduces it into the mixing device 11.

The earth and sand and the soil improving material introduced into the mixing device 11 are uniformly stirred and mixed by the paddle mixer in the mixing device 11 and discharged onto the conveyor belt 42 of the discharge conveyor 3. Then, the improved soil is further conveyed to the other side of the self-propelled soil conditioner by the discharge conveyor 3, and finally discharged from the end of the self-propelled soil conditioner.

Here, the turning operation of the self-propelled soil improvement machine of the above basic operation will be described. For example, when a predetermined operation is performed using an operation panel or the like (not shown) provided in the driver's seat 44, a turning control valve (not shown) is switched, and the turning motor 47 is discharged from the hydraulic pump (not shown) to the turning motor 47 accordingly. The pressure oil is switched and supplied. When the pressurized oil is supplied, the turning motor 47 is driven forward or reverse (strictly, the drive unit 50), and is decelerated by the speed reduction mechanism 51 to be transmitted to the pinion 52. The pinion 52 to which the rotation has been transmitted meshes with the internal gear 57 of the turning wheel 53 and revolves while rotating, whereby the inner ring 54 rotates relatively to the outer ring 55, as shown in FIG. The soil improvement function component 4 turns clockwise or counterclockwise in FIG.

That is, in the present embodiment, the soil improvement function component 4 is provided so as to be able to turn on the traveling body 1, so that the receiving side of the self-propelled soil improvement machine (that is, the soil to be reformed is removed). The positions of the input hopper 10 and the discharge side (that is, the side of the discharge conveyor 3 for discharging the improved soil) can correspond to the surrounding environment at the operation site.

The operation of the self-propelled soil conditioner of the present embodiment, which operates as described above, was performed using the self-propelled soil conditioner of the present embodiment shown in FIGS. The operation will be sequentially described below with reference to working examples.

FIG. 6 is a diagram showing an example of one soil improvement operation using one embodiment of the self-propelled soil improvement machine of the present invention. The example of the soil improvement work shown in FIG. 6 is an example of a case where a plurality of types (three types in this example) of improved soils having different soil properties are generated and separated and accumulated at different locations, respectively.
S2 and S3 are accumulation positions of a plurality of types of improved soil that are separated and accumulated. In addition, P1, P2, and P3 are provided at a plurality of locations (three locations in this example) around the self-propelled soil improvement machine 100, and are the accumulation positions of the soil to be reformed, which is a material of three types of improved soil. is there.

Here, using a conventional self-propelled soil improvement machine,
For example, in the case where the soil to be reformed accumulated at the positions P1, P2, and P3 is charged by a hydraulic shovel or the like and reformed, the conventional self-propelled soil improvement machine has a traveling body equipped with a hopper, a mixing device, and the like. Since it is fixedly connected to the main body frame, after the soil to be reformed at the position P1 is reformed and accumulated at the position S1, for example, the soil to be reformed accumulated at the position P2 is reformed and the position S2 is modified. When moving to work to accumulate in
The position of the downstream end of the discharge conveyor in the transport direction is set to the position S1.
The driving body is controlled so that the hopper comes near the position P2 from the position P2 so that the position of the hopper which is near the position P1 also comes close to the position P2 in consideration of the sediment loading workability. The position of the machine itself must be finely controlled.
As can be seen from the positional relationship among the positions P1, P2, S1, and S2 shown in FIG. 6, this position adjustment operation needs to appropriately combine operations such as so-called pivot turn, turnback, and width shifting, and is not necessarily sufficient. This is very troublesome work in an operation site where a work space is not always secured.

On the other hand, in the present embodiment, for example, after the soil to be reformed at the position P1 is reformed and accumulated at S1, the soil to be reformed accumulated at the position P2 is reformed and accumulated at the position S2. When shifting to the work, the soil improvement function component 4 is connected to the turning motor 47 so that the soil injection work can be performed smoothly without moving the self-propelled soil improvement machine 100 itself.
Is driven to rotate appropriately, and the receiving side (that is, the sieve device 9 and the hopper 10 side) is moved from the position P1 to the position P2.
Can be approached. At the same time, the discharge side (that is, the discharge conveyor 3 side) also turns from the position S1 to the vicinity of the position S2.

After that, when shifting to the operation of reforming the soil to be reformed accumulated at the position P3 and accumulating it at the position S3, the turning motor 47 is similarly driven to operate the soil improvement function constructing section 4. Is appropriately rotated to move the receiving side (ie, the sieve device 9 and the hopper 10 side) from the position P2 to the position P3.
To the discharge side (that is, the discharge conveyor 3 side)
Can be turned from the position S1 to the vicinity of the position S2.

In this example, the accumulating position of the improved soil is set at three places.
While the soil improvement function component 4 is sequentially turned and displaced with respect to the traveling body 1, the soil to be reformed is introduced into the receiving side of the soil improvement function component 4, and the soil is improved at a plurality of locations around the discharge side of the soil improvement function component 4. Improved soil can be accumulated.

Therefore, according to the present embodiment, it is possible to easily distribute and discharge the improved soil produced from various types of soil at the operation site, thereby reducing the load of the above-mentioned position adjustment work and improving the soil quality. Work efficiency can be improved.

Although not particularly shown in order to prevent complication, in the above, the operation of charging the soil to be reformed into the hopper 10 (strictly to the sieve device 9) of the self-propelled soil conditioner 100 is as follows. It may be performed by a self-propelled loading machine such as a hydraulic excavator 200 (see FIG. 7 described later).

FIG. 7 is a diagram showing an example of an operation by a soil improvement system using an embodiment of a self-propelled soil improvement machine according to the present invention. As shown in FIG. 7, the soil improvement system includes the self-propelled soil improvement machine 100 and a hydraulic excavator 200 for charging the self-propelled soil improvement machine 100 with the soil to be reformed. In this work example, such a soil improvement system is used, for example, in ground improvement work or the like, a ground surface layer to be improved is excavated by a hydraulic excavator 200, and the excavated soil is self-propelled by a self-propelled soil improvement machine 100 on the spot. This is an example of reforming and backfilling a site already excavated. The ground improvement work is, for example, to improve the ground of a surface layer portion of a warehouse, a residential land, or the like, to secure sufficient ground strength by compacting later, and to prevent uneven settlement.

In FIG. 7, W1 is an area to be ground-improved, W2 is an area that has already been ground-improved and compacted, or an area that is strong enough to allow the unexcavated soil improvement system to work. The target area W1 is
The unexcavated area (the area to be excavated by the excavator 200) W1a and the excavated area (the excavator 20
A region W1b excavated by 0) and an already improved region (a region in which the improved soil is backfilled) W1c.

Here, conventionally, when such a ground improvement work is performed, for example, a cement-based soil improvement material or the like is evenly scattered in the ground improvement target area W1, and this area is, for example, a hydraulic excavator 200, for example. Excavation was performed together with the soil improvement material using construction equipment, and the excavated earth and sand and the soil improvement material were mixed. However, such an operation has problems such as scattering of dust and poor mixing efficiency, and has become less desirable.

Further, even when the conventional self-propelled soil improvement machine is used, the conventional self-propelled soil improvement machine can be used in the transportation direction of the soil and the improved soil (the self-propelled soil improvement machine of the present embodiment). 100
In other words, since the running direction is substantially the same as the running direction of the soil improvement function constituting section 4), for example, when the excavation site is sequentially moved in the direction of arrow C in FIG. The moving operation must be performed separately, and as described above, the operation of adjusting the position of the soil conditioner itself accompanying the moving operation is very troublesome.

Further, in order to perform the movement and soil improvement work in parallel using the conventional self-propelled soil improvement machine, for example, a return conveyor or the like that can turn the transport conveyor with respect to the traveling body is used. Machines must be separately arranged, the number of machines constituting the soil improvement system increases, and there is a case where it is not possible to sufficiently cope with an operation site where sufficient space is not always secured.

On the other hand, in this working example, as shown in FIG. 7, the self-propelled soil conditioner 100 and the hydraulic excavator 200 are placed in this area W2 in the front-rear direction (so that the traveling directions are the same). They are arranged in tandem. The self-propelled soil improvement device 100 adjusts its soil improvement function component 4 so that the discharge conveyor 3 is positioned above the lateral side of the traveling body 1 with respect to the front-rear direction (that is, the ground improvement target area W1). It is turned by a predetermined angle. In this state, the excavated soil is excavated from the excavated area W1b (strictly, from the right end in FIG. 7 of the unexcavated area W1a) by the hydraulic excavator 200 to the hopper 10 of the self-propelled soil conditioner 100 (strictly). To the sieve device 9). Then, the input soil is reformed by the self-propelled soil conditioner 100 to improve the already improved region W1c.
(Strictly, to the right end portion in FIG. 7 of the excavated area W1b).

At this time, as described above, since the self-propelled soil conditioner 100 and the excavator 200 are arranged in tandem so that their traveling directions are the same, the self-propelled loading machine 100 and hydraulic excavator 200
Can be sequentially moved in the direction of the excavator 200 (ie, the direction of arrow C in FIG. 7). Thus, in the present working example, the ground improvement work can be performed efficiently.

Even when the width of the ground improvement target area W1 is relatively large, the improved soil discharged from the discharge conveyor 3 is within the width of the ground improvement target area W1 by using the self-propelled soil improvement machine 100. By turning the soil improvement functional component 4 so that the soil is uniformly laid, the burden of the work of laying and compacting the backfilled improved soil can also be reduced.

In the above description, the self-propelled soil improvement machine 100
A self-propelled soil improvement machine comprising a soil improvement function component that mixes and discharges the soil to be reformed according to the claims with the soil improvement material, and is rotatably provided on the traveling body. Hydraulic excavator 200 constitutes a self-propelled loading machine for charging the soil to be reformed to the self-propelled soil improvement machine.

FIG. 8 is a diagram showing another example of the operation of the soil improvement system using one embodiment of the self-propelled soil improvement machine of the present invention. As shown in FIG. 8, this soil improvement system also includes the self-propelled soil improvement machine 100 and the hydraulic excavator 200. In the present working example, the soil improvement mountain P4 to be reformed is modified using the soil improvement system. This is an example in which the soil to be treated is fed into the self-propelled soil conditioner 100 by the hydraulic excavator 200 to generate the improved soil, and the generated improved soil is loaded on a transportation means such as the dump truck 300 shown in FIG. 8 for transporting the generated improved soil. .

In FIG. 8, W3 is a temporary road through which the dump truck 300 travels, and W4 is a work area of the soil improvement system which is buried one step higher than the temporary road W3, for example. The improved soil produced by the system is, for example, on a road construction site (not shown) on the extension of the temporary road W3 (in this example, on the right in FIG. 8, that is, on the extension in the direction of arrow D). Used as subgrade material to be laid.

That is, in this working example, the dump truck 300 loads the bed improvement soil on the temporary road W3 shown in FIG. 8 and travels in the direction of arrow D in FIG. Convey the improved soil. In this road construction site, the improved soil carried by the dump truck 300 is sequentially spread on the temporary road W3, and the soil is sequentially compacted to construct a road toward the soil improvement work site shown in FIG. I will do it. Therefore, the soil improvement work site shown in FIG. 8 sequentially moves in the direction E opposite to the arrow D in FIG.

In consideration of the workability of loading the improved soil into the dump truck 300 on the temporary road W3, the improved soil discharged from the discharge conveyor of the self-propelled soil improvement machine is directly received by the bed of the dump truck 300. Therefore, it is necessary to protrude the discharge conveyor of the self-propelled soil improvement machine onto the temporary road W3.

When this series of work is performed by a soil improvement system using a conventional self-propelled soil improvement machine, the work area W
4, the improved soil is generated and temporarily accumulated on the ground, and the collected soil is dumped by a loading means such as a hydraulic shovel.
0 or load the discharge conveyor on the temporary road W
3, as described above, the transport direction of the soil and the improved soil (the self-propelled soil improvement machine 1 of the present embodiment).
00, the running direction is substantially the same as the longitudinal direction of the soil improvement function component 4, and therefore, the improved soil is separated from the boundary between the temporary road W3 and the work area W4 by a predetermined distance. It is necessary to drive-control the traveling body and adjust the position and orientation of the self-propelled soil improvement machine itself so that the transport direction has a predetermined angle.

That is, each time the soil improvement work site is moved, the above-mentioned position and orientation adjustment work must be performed in accordance with the movement work and the shift to the soil improvement work. At the work site, the dump truck 300 coming and going on the temporary road W3 is crowded, and the work area W4 of the soil improvement system often does not have sufficient space. The operation of adjusting the position and orientation of the machine itself is very troublesome.

On the other hand, in this working example, as shown in FIG. 8, the self-propelled soil conditioner 100 and the hydraulic excavator 200 are placed in this working area W4, and their running directions are the same as the moving direction E of the soil improving site. They are arranged in tandem in the same direction. The self-propelled soil improvement device 100 secures a predetermined distance to the boundary between the temporary road W3 and the work area W4, and displaces the soil improvement function component 4 by a predetermined angle with respect to the traveling body 1 to discharge the conveyor. 3 protrudes above the temporary road W3.

At this time, when moving the soil improvement work site, the traveling direction of the self-propelled soil improvement machine 100 (soil improvement system) is almost the same as the movement direction E of the soil improvement work site. Even in a narrow work space, it is possible to reduce the burden on the work of adjusting the position and orientation of the self-propelled soil improvement machine itself. Also, when the soil improvement system is transported by a transportation means such as a trailer when moving the soil improvement work site, the traveling direction of the transportation means, the self-propelled soil improvement machine 100,
In addition, since the loading direction of the excavator 200 to the transportation means is substantially the same as the moving direction E of the soil improvement work site, the excavator 200 can move efficiently even in a narrow space.

Further, in the self-propelled soil improvement machine 100, since the soil improvement function component 4 can be turned, the degree of freedom within the width of the temporary road W3 at the downstream end of the discharge conveyor 3 in the transport direction can be secured. In order to directly receive the improved soil on the loading platform, the dump truck 300 starts to adjust its position so that the loading platform is positioned below the downstream end of the discharge conveyor 3 of the self-propelled soil conditioner 100 in the transport direction. The burden can be reduced, and the workability of loading the improved soil can be improved.

In the above description, the self-propelled soil improvement machine 100 also includes a soil improvement function component that mixes and discharges the soil to be reformed with the soil improvement material described in each of the claims. A hydraulic excavator 200 constitutes a self-propelled loading machine for charging the soil to be reformed to the self-propelled soil improving machine.

FIG. 9 is a diagram showing still another example of the operation of the soil improvement system using one embodiment of the self-propelled soil improvement machine of the present invention. As shown in FIG. 9, this soil improvement system also has the self-propelled soil improvement machine 100 and the hydraulic excavator 200. In this work example, the soil improvement mountain P5 to be reformed is also modified using the soil improvement system. This is an example in which the soil to be treated is injected into a self-propelled soil conditioner 100 by a hydraulic excavator 200 to generate improved soil, and is loaded on a transportation means such as a dump truck 300, for example. In this working example, the dump truck 300 loads the improved soil directly from the soil conditioner 100 on its carrier and transports the improved soil to another location.
At the time of loading the improved soil, in this example, the dump truck 300 has its traveling direction set to the arrow F direction in FIG. 9 and the loading platform is located below the downstream end of the discharge conveyor 3 of the self-propelled soil conditioner 100 in the transport direction. Adjust its position to come.

At this time, considering the workability of loading the improved soil, the end position (improved soil discharge position) on the downstream side in the transport direction of the discharge conveyor of the self-propelled soil conditioner is sufficient for the traveling body. It is desirable to secure a distance. That is, if this distance is sufficiently secured, the dump truck 300
Can accept improved soil over a large area of its bed. In order to avoid collision between the dump truck 300 and the self-propelled soil conditioner 100 at the time of receiving the improved soil, the distance between the dump truck 300 and the traveling body 1 of the self-propelled soil conditioner 100 is secured. For this reason, it is desirable that the distance between the downstream end position of the discharge conveyor of the self-propelled soil improvement machine in the transport direction and the traveling body is ensured.

Normally, a traveling body such as a self-propelled soil improvement machine has its traveling direction set to the longitudinal direction. Therefore, the soil improvement machine 100 of the present embodiment includes
, The longitudinal direction (the direction of transport of the improved soil, that is, the longitudinal direction of the soil quality improving function component 4) can be set to the lateral direction of the traveling body 1 by making a turning displacement so as to be substantially perpendicular to the traveling body 1. Compared to a conventional self-propelled soil improvement machine whose longitudinal direction (the direction of transport of the improved soil) and the longitudinal direction of the traveling direction are almost the same, the position of the downstream end of the discharge conveyor in the transport direction and the traveling body A long distance can be secured.
Therefore, the workability of loading the improved soil into the dump truck 300 can be improved, and the dump truck 300 and the self-propelled soil conditioner 10 during the improved soil loading operation can be improved.
The possibility of collision with zero can be reduced.

In the above description, the self-propelled soil improvement machine 100 also includes a soil improvement function component for discharging the soil to be reformed mixed with the soil improvement material described in each of the claims. A hydraulic excavator 200 constitutes a self-propelled loading machine for charging the soil to be reformed to the self-propelled soil improving machine.

As described above, according to the present embodiment, the work efficiency in the whole soil improvement work can be improved by arranging the soil improvement function component 4 on the traveling body 1 so as to be pivotable.

A rotary shaft 69, a cylindrical body 70 made of, for example, a steel pipe, and rotatably inserted through the rotary shaft 69, a cylindrical body 70 and the secondary conveyor 58.
And a connecting portion 71 for connecting the frame 61 to the frame 61.

Reference numeral 72 designates the mounting portion 67, which is a bracket for holding the upper end of the rotary shaft 69. The bracket 72 is fixed to the upper surface of the power device 43 via a plate-like member 73 fixed by, for example, welding. (Right side in FIG. 10).
Reference numeral 73 (see FIG. 10) is a truss for ensuring the support strength of the bracket 72.

Numerals 74 and 75 are holding members for holding the frame 61 of the secondary conveyor 58. The holding members 74 and 75 constitute a plurality of truss-like support members 7 respectively.
It is fixedly connected to the cylindrical body 70 via 6, 77.

Numeral 78 denotes a hydraulic cylinder for rotating the secondary conveyor 58 with respect to the body 2 'of the soil conditioner. Both ends of the hydraulic cylinder are projected and fixed to the cylindrical body 70 by, for example, welding as shown in FIG. The bracket 79 and the bracket 80 fixed to one side (the right side in FIG. 10) of the power unit 43 are rotatably connected by pins 81 and 82, respectively. That is, when the hydraulic cylinder 78 expands and contracts, the secondary conveyor 58 is driven to rotate with respect to the soil improvement machine main body 2 ′.

The hydraulic cylinder 78 is connected to a hydraulic pump (not shown) provided in the power unit 43 via a rotation control valve (not shown). Further, a rotation control valve (not shown) also constitutes the control valve device (not shown) provided in the power unit 43, for example, and is switched by an operation panel (not shown) provided in the driver's seat 44, for example.

In the present embodiment, since the hydraulic cylinder 78 is arranged as shown in FIG. 12 in the rotation range of the secondary conveyor 58, it can be rotated by approximately 90 ° in the direction of arrow G in FIG. It is. On the other hand, in the direction of arrow H in FIG. 13, the rotation range does not reach 90 °, but if, for example, the rotation shaft 69 of the support frame 66 is connected to a hydraulic motor, A sufficient rotation range can be ensured in both directions of the middle arrow G and the arrow H. Other configurations are the same as those of the above-described embodiment.

In the above, the support frame 66 is
The secondary conveyor according to each claim constitutes a supporting means for rotatably supporting the main body of the soil improvement machine, and the hydraulic cylinder 78 connects the secondary conveyor to the main body of the soil improvement machine. A driving means for rotationally driving the motor is constituted.

According to the self-propelled soil conditioner 100A of this embodiment having the above-described configuration, the secondary conveyor 58 for discharging the improved soil is provided rotatably with respect to the soil conditioner main body 2 '. As shown in FIG. 13, for example, the secondary conveyor 58 is connected to the hydraulic cylinder 78 as in the first embodiment.
Is driven to rotate appropriately, and the accumulation position of the generated improved soil is stored at a plurality of positions (in this example, three positions S4, S5, and S6).
Although the location is illustrated, it may be more or less). That is, the improved soil discharge position can be made to correspond to the surrounding environment at the operation site. When changing the improved soil accumulation position, the traveling body 1 is drive-controlled to move the self-propelled soil conditioner 100A itself. Even if it is not necessary, the secondary conveyor 58 can be appropriately rotated and driven so that the above-described improved soil discharging position is a desired place. Therefore, at the operation site, the improved soil produced from various types of soil can be easily distributed and discharged, thereby reducing the burden of the position adjustment work described above and improving the work efficiency of the soil improvement work. be able to.

Although not particularly shown in FIG. 13 to prevent complication, the hopper 10 of the self-propelled soil conditioner 100A is not shown.
Needless to say, the operation of charging the soil to be reformed into the sifting device 9 (strictly to the sieving device 9) may be performed by a self-propelled charging machine such as a hydraulic shovel 200 (see FIG. 7).

Further, as shown in FIG. 14 showing an example of the operation of the soil improvement system using the self-propelled soil improvement machine 100A, the soil improvement system is connected to the self-propelled soil improvement machine 10A.
The same work as the work example described above with reference to FIG. 7 can be performed by using the hydraulic excavator 200 and the hydraulic excavator 200.

That is, as shown in FIG. 14, the self-propelled soil conditioner 100A and the hydraulic excavator 200 are arranged in tandem in the soil condition improvement work area W6 so that the traveling directions are the same. Self-propelled soil improvement machine 10
The secondary conveyor 58 of 0A is positioned with respect to the soil improvement machine main unit 2 'such that the downstream end position of the secondary conveyor 58 in the transport direction is located above the lateral side with respect to the front-rear direction (that is, the ground improvement target area W5). An angle (in FIG. 14, a state of being rotated by approximately 90 ° is shown) is rotated and displaced. In this state, the excavated soil is excavated from the excavated area W5b by the hydraulic excavator 200 (strictly, from the right end in FIG. 14 of the unexcavated area W5a) to the hopper 10 of the self-propelled soil conditioner 100A (strictly). Into the sieve device 9). Then, the self-propelled soil improvement machine 100A reforms the input soil and buryes it in the already improved area W5c (strictly, in the right end portion of the already excavated area W5b in FIG. 14).

Also in this working example, since the self-propelled soil conditioner 100A and the hydraulic excavator 200 are arranged in tandem so that their running directions are the same, the self-propelled loading machine 100A And excavator 20
0 in the direction of the excavator 200 (ie, FIG.
(In the direction of the middle arrow I). Thus, also in this working example, the ground improvement work can be performed efficiently.

Even when the width of the ground improvement target area W5 is relatively large, the self-propelled soil improvement machine 100A can be used.
By rotating the secondary conveyor 58 so that the generated improved soil is evenly laid within the width of the ground improvement target region W3, the work of spreading and burying the backfilled improved soil is then performed. Needless to say, the burden can be reduced.

In the above, the self-propelled soil conditioner 100A
According to each of the claims, a hopper for receiving the soil to be reformed, a mixing device that mixes the soil to be reformed conveyed from the hopper with a soil quality improving material to produce an improved soil, and the mixing device A soil improvement machine main body section having a primary conveyor for transporting the generated improved soil, and a rotatable rotary body mounted on the soil improvement machine body section for discharging the improved soil received from the primary conveyor. A self-propelled soil improvement machine comprising a next conveyor and a hydraulic excavator 200
It constitutes a self-propelled loading machine that loads the target soil into the self-propelled soil improvement machine.

Further, as shown in FIG. 15 showing another working example of the soil improvement system using the self-propelled soil improvement machine 100A, the soil improvement system is constructed by the self-propelled soil improvement machine 100A and the hydraulic excavator 200. With the configuration, the same operation as the operation example described above with reference to FIG. 8 can be performed.

That is, using the soil improvement system, the soil to be reformed of the soil pile P6 to be reformed is transferred to the hydraulic excavator 20.
At 0, the soil is introduced into the self-propelled soil improvement machine 100A to generate the improved soil, and while the loaded soil is loaded on the transportation means such as the dump truck 300, the soil is appropriately moved in the direction of arrow K in FIG.

Also in this case, the self-propelled soil conditioner 100A and the excavator 200 are arranged in the work area W8 in a cascade such that their traveling directions are the same as the direction K in which the soil improvement site sequentially moves. At this time, the self-propelled soil conditioner 100A secures a predetermined distance to the boundary between the temporary road W7 and the work area W8, and moves the secondary conveyor 58 to a predetermined angle ( In FIG. 15, the secondary conveyor 58 is rotated and displaced by approximately 90 °), and the secondary conveyor 58 is protruded above the temporary road W7 to load the improved soil into the dump truck 300.

Also, when moving the soil improvement work site, the traveling direction of the self-propelled soil improvement machine 100A (soil improvement system) is substantially the same as the moving direction K of the soil improvement work site. Even in a narrow work space, it is possible to reduce the burden of adjusting the position and orientation of the self-propelled soil improvement machine itself as described above. Further, when the soil improvement system is transported by a transportation means such as a trailer when moving the soil improvement work site, the traveling direction of the transportation means, the transportation means of the self-propelled soil improvement machine 100A and the hydraulic shovel 200 It is needless to say that the loading direction to the soil improvement work site is almost the same as the moving direction E, so that the vehicle can be moved efficiently even in a small space.

Further, in the self-propelled soil improvement machine 100A, since the secondary conveyor 58 is rotatable, the degree of freedom within the width of the temporary road W7 at the downstream end position in the transport direction can be secured, and the self-propelled soil improvement machine can be directly improved by its loading platform. In order to receive the soil, the dump truck 300 moves its loading platform to the self-propelled soil conditioner 100A.
Needless to say, the burden on the work of adjusting the position of the secondary conveyor 58 so as to be located below the downstream end in the transport direction of the secondary conveyor 58 can be reduced, and the workability of loading the improved soil can be improved.

Also in the above, the self-propelled soil improvement machine 100
A is a hopper for receiving the soil to be reformed according to the claims, a mixing device for mixing the soil to be reformed conveyed from the hopper with a soil improving material to produce an improved soil, and the mixing device Soil improvement machine main body provided with a primary conveyor for transporting the improved soil generated by the method, and the soil improvement machine body is provided rotatably with respect to the soil improvement machine main body, and discharges the improved soil received from the primary conveyor. A self-propelled soil improvement machine including a secondary conveyor is configured, and the hydraulic excavator 200
Constitutes a self-propelled loading machine that loads the soil to be reformed into the self-propelled soil improvement machine.

As described above, according to the present embodiment, 2
The work efficiency in the whole soil improvement work can be improved by providing the next conveyor 58 so as to be rotatable with respect to the soil improvement machine main body 2 ′.

Another embodiment of the self-propelled soil improvement machine of the present invention will be described with reference to FIGS. FIG.
FIG. 17 is a side view showing the overall structure of still another embodiment of the self-propelled soil improvement machine of the present invention, and FIG. 17 is a top view thereof, corresponding to FIGS. The same parts as those in FIG. 2 are denoted by the same reference numerals and description thereof will be omitted. This embodiment is an embodiment in which the features of the above-described one embodiment and other embodiments are combined.

As shown in FIGS. 1 and 2, the self-propelled soil conditioner 100B according to the present embodiment comprises the traveling body 1, the soil conditioner main body 2 ', and a rotatable body. And a soil improvement function component 4 'comprising the secondary conveyor 58 provided. Similar to the first embodiment, the soil improvement function component 4' is (strictly speaking, the soil improvement machine body 2). ') Is provided on the traveling body 1 so as to be able to turn.

The turning support structure of the soil improvement function component 4 'and the turning support structure of the secondary conveyor 58, including the drive structure thereof, are the same as those of the first and second embodiments, respectively. The same as the improved machines 100 and 100A,
Other basic configurations are also self-propelled soil improvement machines 100 and 10
Same as 0A.

The self-propelled soil improvement machine 100 having the above structure
According to B, the same effects as those of the above-described one embodiment and other embodiments can be obtained, and the degree of freedom of the relative positional relationship between the modified soil receiving position and the improved soil discharging position is further improved. be able to.

Normally, for example, when accumulating the generated improved soil on the ground or the like, if the height of the improved soil becomes higher with the progress of the work, the mountain comes into contact with the conveyor from which the improved soil is discharged. there is a possibility. Also in this case, if the self-propelled soil conditioner 100, 100A, 100B of each embodiment described above is used, the accumulated soil can be improved without moving the self-propelled soil conditioner itself. The discharge position of the improved soil can be easily changed in order to prevent contact with the conveyor for discharging the soil.

In the above description, the crawler 8 as the running body 1
Although the self-propelled soil improvement machine provided with the above has been described as an example, the present invention is not limited to this. For example, the above embodiments may be applied to a self-propelled soil improvement machine provided with a wheeled traveling body. Furthermore, the sieving device 9 is a vibration sieve, but is not limited thereto and may be a fixed sieve. In these cases, a similar effect is obtained.

Further, for example, a rotary striker is provided inside,
Similar effects can be obtained even when the above-described embodiments are applied to a self-propelled soil improvement machine equipped with a so-called crushing type mixing device that crushes and mixes the earth and sand and the soil improvement material with this rotary striker. Needless to say.

[0117]

According to the first aspect of the present invention, the soil improvement function component is provided so as to be capable of turning on the traveling body, so that the receiving side of the self-propelled soil improvement machine (that is, the soil to be reformed) is provided. The position on the hopper side for charging the wastewater and the position on the discharge side (that is, on the discharge conveyor side for discharging the improved soil) can correspond to the surrounding environment at the operation site. Thereby, when changing the soil to be reformed, the soil improvement function component is appropriately rotated and driven so that the soil injection work can be performed smoothly without moving the self-propelled soil improvement machine itself, and the receiving side is changed. It is possible to approach other earth and sand input work positions. At this time, since the discharge side of the generated improved soil also makes a turning displacement together with the turning movement of the receiving side, it is possible to easily sort and discharge the improved soil produced from various types of soil at the operation site.

According to the ninth aspect of the present invention, the secondary conveyer for discharging the improved soil is provided rotatably with respect to the main body of the soil conditioner, so that the improved soil discharge of the self-propelled soil conditioner is achieved. The position (ie, the position of the downstream end of the secondary conveyor in the transport direction) can correspond to the surrounding environment at the operation site. As a result, when changing the accumulation position of the improved soil,
Even without moving the self-propelled soil improvement machine itself, the secondary conveyor can be driven to rotate appropriately so that the improved soil discharge position is the desired location. Each of the improved soils can be easily sorted and discharged.
