Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fine-graining apparatus for finely graining improved soil produced by mixing and coarsely pulverizing a dewatered cake and a soil improvement material, and a leveling member used for the same. .

[0002]

2. Description of the Related Art In a crushed stone factory, for example, most of dewatered cakes produced by dewatering wastewater obtained by washing fine crushed stone powder generated in a classification step with a filter press are effectively used. Without being buried or treated as industrial waste. However, in the context of the recent promotion of waste recycling, research and research on its effective use has been advanced in various fields, and the dehydrated cake must be modified with quick lime and other soil improvement materials and mixed with crusher or regenerated crusher orchid. It has recently become clear that high-quality hydraulic composite roadbed materials can be manufactured, and in response to this, the dewatered cake is mixed and coarsely crushed with a soil improvement material using, for example, a self-propelled soil improvement machine, and the improved soil product is manufactured. Manufacturing is beginning to take place.

On the other hand, the Ministry of Construction, the Association of Crushed Stone, the Association of Lime, and the like have established new manufacturing standards for high-quality hydraulic composite roadbed materials. A high level of grain refinement of 5% or less (content rate of those with a diameter of 5 mm or less) has been set, but conventionally, a system that can realize such a high-level grain refinement from improved soil generated based on a dewatered cake. Did not exist.

[0004] By the way, the purpose of the present invention is not to make the improved soil produced from the dewatered cake finer (finely disintegrate), but to make the soil generated during construction or civil engineering work into soil. For example, as described in Japanese Patent Application Laid-Open No. 2000-45326, a construction conveyed soil is conveyed by a conveyer (conveying means), and conveyed construction generated soil is conveyed. Has been proposed in which a crusher (rotating blade crushing body) internally provided with a cutter (rotating blade) in which the cutters are arranged at substantially equal intervals in the width direction of the transport conveyor has been proposed.

[0005] Therefore, it is conceivable to apply the above-mentioned prior art grain refiner to an improved soil produced from a dewatered cake to perform grain refinement of a high standard.

[0006]

However, when the above-mentioned prior art is applied to refinement of the improved soil produced from the dewatered cake, the following problems exist. That is, when the improved soil is conveyed by the conveyor, on the conveyor belt of the conveyor, the improved soil is not necessarily placed in a smooth state in the width direction. It is often conveyed in a mountain-like state. In such a case, the refined soil is refined by a part of the cutter disposed near the center in the width direction of the conveyor of the crusher. In other words, the cutter arranged outside the width direction of the conveyor hardly performs the crushing work, so that the crushing performance of the entire crusher cannot be sufficiently exhibited,
As a result, the crushability of the improved soil may decrease.

An object of the present invention is to provide a fine-graining apparatus capable of improving the crushability of an improved soil produced by mixing and coarsely crushing a dewatered cake and a soil improvement material, and a leveling member used for the same. To provide.

[0008]

Means for Solving the Problems (1) In order to achieve the above object, the present invention provides a method for transporting improved soil generated from a dewatered cake by a transport conveyor having a transport belt.
In the grain refiner for crushing by the at least one crusher provided on the conveyor, the improved soil to be conveyed is leveled at a position above the conveying surface of the conveyor belt and on the upstream side in the conveying direction of the crusher. A leveling member is provided.

For example, when the improved soil conveyed on the conveyor is crushed by the crusher in which the cutters are arranged at regular intervals in the width direction of the conveyor as described above, for example, when the conveyor is transported, When the improved soil is conveyed in the state of a high mountain near the center in the width direction of the belt, the load is biased to the cutters arranged near the center in the width direction of the conveyor, and the cutters arranged outside the conveyor in the width direction are almost all. Since the crushing operation is not performed, as a result, the performance of the crusher as a whole may not be sufficiently exhibited.

Therefore, in the present invention, the leveling member is provided at a position above the conveying surface of the conveying belt of the conveying conveyor constituting the grain refining device and on the upstream side in the conveying direction of the crusher. Even when the improved soil is conveyed in a mountain-like state, the hills are leveled and the improved soil can be arranged substantially uniformly over substantially the entire length in the width direction of the conveyor belt. Thereby, the load biased to the cutter near the center in the width direction of the transport conveyor can be uniformly distributed to the cutter arranged outside the width direction of the transport conveyor. Therefore, the improved soil generated by mixing and coarsely crushing the dewatered cake and the soil improvement material can be efficiently crushed, and the crushability can be improved.

(2) In the above (1), preferably,
The leveling member has at least one plate-shaped member in contact with the surface of the conveyed improved soil.

As described above, by providing the plate-shaped member in contact with the surface of the improved soil to be conveyed, a raised portion of the above-described improved soil near the center in the width direction of the conveyor belt is cut out outward in the width direction on the conveyor belt. The improved soil can be arranged uniformly and smoothly over almost the entire length in the width direction on the conveyor belt.

(3) In the above (2), preferably,
The plate-shaped member has an expanded shape toward the downstream side in the transport direction of the transport conveyor.

(4) In the above (3), preferably, the plate-like member has an upper portion inclined downward in the transport direction of the transport conveyor.

(5) In the above (1), preferably, the leveling member is provided substantially perpendicular to the transport surface of the transport belt so as to level the improved soil to be transported. It has a plurality of rod-shaped members.

For example, when the improved soil discharged from the discharge conveyor of the self-propelled soil improvement machine is directly supplied to the grain refiner by dropping it on the transfer surface of the transfer conveyor, for example, the improved soil is high. In the case of a viscous and high water content state, the supplied improved soil may adhere to the transport surface of the transport conveyor. In such a case, there is usually a slight gap between the tip of the cutter and the transport surface, for example, of the cutter, so that the loose soil near the transport surface is not disintegrated at all. It may pass through the crusher.

Therefore, in the present invention, the leveling member is constituted by a plurality of rod-like members provided substantially perpendicularly to the conveying surface of the conveying belt. The improved soil conveyed in a mountain-like state on the conveyed belt can be evenly evenly distributed over substantially the entire length of the conveyor belt in the width direction, and the improved soil adhering near the conveying surface as described above. And can be transported to a crusher in a crushable state.

(6) In the above (5), preferably,
The plurality of bar-shaped members are arranged at substantially equal intervals in the width direction of the transport conveyor.

(7) In the above (5), preferably, the plurality of rod-shaped members are relatively dense near the center in the width direction of the conveyor, and relatively sparse near the outer side in the width direction of the conveyor. Are located in

(8) Any one of the above (1) to (7)
More preferably, the transport conveyor is provided so as to be tiltable in the transport direction.

As described above, by making the transport conveyor tiltable in the transport direction, the transport angle of the improved soil can be arbitrarily changed. As a result, for improved soils that require sufficient crushing, such as improved soils with high viscosity or large lumps, for example, the residence time of the improved soil on the conveyor is sufficient as a relatively large ascending slope. As a result, sufficient crushability can be obtained. On the other hand, for improved soils that do not require so much crushing treatment, such as fragile improved soils with relatively low moisture content and improved soils that do not contain a large amount of lumps, the improved soils should have a relatively gentle upslope to smoothly It is also possible to improve the production efficiency by shortening the time for conveying and improving soil on the conveyor.

(9) In order to achieve the above-mentioned object, the present invention provides at least one crusher provided on the conveyor while conveying the improved soil produced from the dewatered cake by the conveyor having the conveyor belt. At least one plate-shaped member provided at a position above the conveying surface of the conveyor belt and upstream of the conveying direction of the crusher, in contact with the surface of the improved soil to be conveyed, Having.

(10) In order to achieve the above object, the present invention provides at least one crusher provided on a conveyor while conveying the improved soil generated from the dewatered cake by a conveyor having a conveyor belt. The refinement device is provided substantially perpendicular to the conveying surface of the conveyor belt at a position on the upstream side in the conveying direction of the crusher above the conveying surface of the conveyor belt, and It has a plurality of rod-like members that stir the soil.

A hopper 52 is provided at the upstream end (right side in FIG. 1) of the conveyor 1 for receiving improved soil.

The most important feature of the present embodiment of the granulating apparatus of the present invention having the above structure is that the chopper 2 is provided on the upper side of the conveyor 1 in the conveying direction upstream of the chopper 2 (right side in FIG. 1). That is, a blade 53 for leveling the improved soil conveyed on the surface 12a is provided.

FIG. 8 is a top view showing the entire structure and mounting structure of the blade 53, FIG. 9 is a front view seen from the direction of arrow I in FIG. 8, and FIG. 10 is a cross section taken along line XX in FIG. In the figure, the same parts as those in the previous figures are denoted by the same reference numerals. As shown in FIGS. 8 to 10, the blade 53 is formed of a plate material made of, for example, a synthetic resin or the like, and is formed in a substantially “V” shape that expands in the transport direction G of the transport conveyor 1.

The mounting plate 58 is provided with a plurality of (four in this example) long holes 58a (see FIG. 10), and the blades 53 are fixed by the bolts 59 through the long holes 58a. Are mounted so that the gap j between the conveyor surface 1 and the conveyor surface 12a of the conveyor 1 can be adjusted. At this time, in order to make the surface of the blade 53 on the upstream side (the right side in FIG. 8) in the transport direction of the transport conveyor 1 as smooth as possible, it is preferable to use, for example, a hexagonal socket head bolt with a countersunk head. Note that, in the present embodiment, the blade 53 is disposed so as to be substantially perpendicular to the transport surface 12a, and its width in the vertical direction in FIG. 8 is shorter than the width of the transport belt 12. .

In the above, at least one of the choppers 2 provided on the transport conveyor described in the claims is described.
And the blade 53 constitutes a leveling member for leveling the improved soil to be conveyed at a position above the conveying surface of the conveying belt and at a position on the upstream side in the conveying direction of the crushing machine. At least one plate-shaped member that is in contact with the surface of the soil is also configured.

Next, the operation of one embodiment of the grain refining device of the present invention having the above-described structure will be described. In FIG. 1, for example, a soil improvement material is mixed with a dewatered cake by a self-propelled soil improvement device, and the improved soil that has been roughly crushed and discharged is introduced into a hopper 52 of a grain refiner. The improved soil introduced into the hopper 52 is transported on the transport surface 12a of the transport conveyor 1 in the transport direction (FIG. 1).
In the middle of the conveyance, the cutter 28 provided in the chopper 2 is struck so as to follow and is finely crushed (granulated). It is discharged from the downstream (left side in FIG. 1) end.

Here, the operation of the grain refining device that operates as described above will be described sequentially. (1) Function of Providing Blade The improved soil conveyed by the conveyor 1 is not necessarily placed on the conveying surface 12a of the conveyor belt 12 in a smooth state in the width direction. Usually, 2 in FIG.
As indicated by the dashed line K, the conveyance surface 12a is often conveyed in a high mountain state near the center in the width direction. In such a case, refinement of the improved soil is performed by a part of the cutter 28 disposed near the center in the width direction of the conveyor 1 of the rotating body 26 provided in the chopper 2. That is,
The cutter 28 arranged on the outer side in the width direction of the conveyor 1 hardly performs crushing work (that is, the cutter 28 arranged on the outer side in the width direction of the conveyor 1 hardly receives a load). The crushing performance of the crusher cannot be sufficiently exhibited, and the crushability may be reduced.

Therefore, in this embodiment, the blade 53 is provided above the transport surface 12a of the transport conveyor 1 and at a position upstream of the chopper 2 in the transport direction.
For example, even when the improved soil is conveyed in a mountain-like state as described above, the mountain is leveled and, as indicated by a two-dot chain line k in FIG. The improved soil can be uniformly and smoothly arranged over the entire area. Thereby, the cutter 28 near the center in the width direction of the conveyor 1 is provided.
Can be evenly distributed to the cutter 28 disposed on the outer side in the width direction of the conveyor 1, and the improved soil generated by mixing and roughly pulverizing the dewatered cake and the soil improvement material can be efficiently decomposed. Since it can be crushed, the crushability can be improved.

(2) Function of Expanding Blades In this embodiment, as shown in FIG. 9, the blades 53 are moved substantially perpendicular to the conveying surface 12a and downstream of the conveying conveyor 1 in the conveying direction. 8, the raised portion of the improved soil near the center in the width direction of the transport belt 12 is efficiently placed on the transport surface 12 as indicated by an arrow L in FIG. The improved soil can be cut out to the outside in the width direction, and the operation of uniformly and smoothly disposing the improved soil over the entire length in the width direction on the transport surface 12a can be more smoothly performed.

(3) Operation of tilting transport conveyor In this embodiment, as shown in FIG. 7, the transport conveyor 1 is tiltable in the transport direction.
The transport angle of the improved soil can be arbitrarily changed. Thereby, for example, high-viscosity improved soil or improved soil including large lumps,
With respect to the improved soil in a state that requires a sufficient crushing treatment, a relatively large ascending slope is used to sufficiently secure the residence time of the improved soil on the transport surface 12a, thereby obtaining sufficient crushability. On the other hand, for improved soils that do not require a sufficient amount of crushing treatment, such as fragile improved soils with relatively low water content and improved soils that do not contain a large amount of lumps, the improved soil should be used as a relatively gentle uphill slope. It is also possible to improve the production efficiency by smoothly transporting the soil and reducing the residence time of the improved soil on the transport surface 12a.

In order to obtain the effect of the above (3), the conveyor 1 is tiltably provided. However, as long as the basic effect of the present invention, ie, the effect of improving the crushability, is obtained, this structure is not necessarily required. It is not necessary to use a fixed structure (the details will be described later). In order to obtain the effect of the above (2), the blade 5
3 is provided substantially perpendicular to the conveying surface 12a, and has a shape that expands toward the conveying direction of the conveying conveyor 1. However, as long as the effect of improving the crushability, which is the basic effect of the present invention, is obtained, the blade shape is increased. Can be modified without departing from the technical idea. Hereinafter, the modifications will be sequentially described with reference to the drawings.

The blade 53 is provided substantially perpendicular to the transfer surface 12a, and is different from the blade 53 in that the blade 53 is formed in a substantially "I" shape and has a longitudinal direction (vertical direction in FIG. 12A). The point is that it is disposed substantially at right angles to the transport direction G of the transport conveyor 1. Similarly, the mounting plate 58B has its side surface substantially perpendicular to the transport surface 12a of the transport conveyor 1 and substantially perpendicular to the transport direction G in the longitudinal direction ( FIG. 12 (a)
It is attached, for example, by welding or the like to a side surface on the upstream side (in the middle right side in FIG. 12A) of the transport conveyor 1 at a substantially central position in the transport direction.

In this modification, similarly to the above embodiment, the blade 53B is attached to the mounting plate 58B with respect to the mounting plate 58B.
By attaching with a bolt 59 through an elongated hole (not shown), a structure in which the gap between the transfer surface 12a and the transfer surface 12a can be adjusted is provided. In the longitudinal direction (FIG. 12)

Another embodiment of the grain refiner of the present invention will be described with reference to FIGS. This embodiment is an embodiment in which a scraper 61 is provided in place of a blade, for scraping the improved soil conveyed on the conveying surface 12a of the conveyor 1. FIG. 16 is a top view showing the entire structure and mounting structure of the scraper 61 provided in another embodiment of the grain refiner of the present invention, and FIG. 17 is a front view as seen from the direction of arrow L in FIG. 18 is a cross-sectional view taken along the line XVIII-XVIII in FIG. 17, which corresponds to FIGS. 8 to 10, respectively. 8 to 10 are denoted by the same reference numerals and description thereof is omitted.

This is the same as the above embodiment.

In the present embodiment, the scraper 61 is provided above the conveying surface of the conveying belt described in the claims.
At the position on the upstream side in the transport direction of the crusher, a leveling member for leveling the improved soil to be transported is configured, and the leveled soil is almost perpendicular to the transport surface of the transport belt so as to level the transported improved soil. A plurality of provided bar members are also configured.

Here, for example, when the improved soil discharged from the discharge conveyor of the self-propelled soil improvement machine is directly dropped onto the conveying surface 12a of the conveying conveyor 1 and supplied to the grain refiner, for example, If the improved soil has a high viscosity and a high water content, the improved soil may adhere to the transport surface 12a of the transport conveyor 1. In such a case, there is usually a slight gap between the leading end 28b of the cutter 28 provided in the chopper 2 and the transport surface 12a.
The improved soil in the vicinity of the conveyed transport surface 12a may pass through the chopper 2 without being crushed at all.

Therefore, in the present embodiment, a plurality of scrapers 61 are provided substantially perpendicularly to the conveying surface 12a of the conveying belt 12, and the above-described scraper 61 is used, for example, so that sand pits are leveled using a rake. Similar to the embodiment, as shown by the two-dot chain line O in FIG. 17, the improved soil conveyed in a mountain-like state on the conveying surface 12a is transferred to the scraper 61 and the downstream of the conveying conveyor 1 on the upstream side in the conveying direction. Side scraper 6

An effect is also obtained in which the improved soil in the vicinity of “a” is woken up and can be broken by the chopper 2.

In this embodiment, as long as the same effects as described above are obtained, it goes without saying that the shape of the scraper may be modified without departing from the technical concept thereof. Hereinafter, the modifications will be sequentially described with reference to the drawings.

FIG. 19 is a front view showing an entire structure and a mounting structure of a modification of the scraper provided in another embodiment of the grain refiner of the present invention, and is a view corresponding to FIG. 17 described above. Also, the same parts as those in FIG. 17 are given the same reference numerals, and description thereof will be omitted. As shown in FIG. 19, in the present modification, the scraper 61 is not attached to the side surface of the support beam 56 at equal intervals as in the above-described other embodiment, and the longitudinal direction of the support beam 56 (in FIG. Near the center (in other words, near the center of the width of the conveyor belt 12 of the conveyor 1 in the width direction) relatively densely, outside the support beam 56 in the longitudinal direction (the horizontal direction in FIG. 19). (The outer side in the width direction of the conveyor) is relatively sparsely arranged. Other structures are the same as those of the other embodiments.

FIG. 20 is a front view showing the entire structure and mounting structure of another modification of the scraper provided in another embodiment of the grain refiner of the present invention, and is a view corresponding to FIG. is there. Also, the same parts as those in FIG. 17 are given the same reference numerals, and description thereof will be omitted. As shown in FIG. 20, in the present modification, in the vicinity of the center of the support beam 56 in the longitudinal direction (left-right direction in FIG. 20) (in other words, near the center of the width of the conveyor belt 12 of the conveyor 1). The straight scraper 61 is moved in the longitudinal direction of the support beam 56 (FIG. 2).
The outer end of the scraper 61A is bent outside the transport surface 12a (in other words, the scraper 61A is inclined outward in the width direction of the transport conveyor 1 with respect to the direction perpendicular to the transport surface 12a of the transport conveyor 1). Are arranged at equal intervals at the predetermined pitch N, for example. At this time, the mounting pitch of each of the scrapers 61, 61A may be the same as that of the modification shown in FIG.

In this modification, the support beam 5
Although a scraper 61A whose tip is bent outside the transport surface 12a on the outside in the longitudinal direction of 6 is disposed, a straight scraper like the scraper 61 may be fixed to the support beam 56 by inclining, The position and number of the inclined scrapers on the support beam 56 are also shown in FIG.
The structure need not be limited to the structure shown in FIG. In short, a plurality of scrapers are provided, and at least a part of at least one of the scrapers is
May be inclined in the width direction. Other structures are the same as those of the other embodiments.

In both of the above-described modifications, the same effects as those of the other embodiments can be obtained. In particular, FIG.
In the modification of No. 9, since the scrapers 61 are relatively densely arranged near the center in the width direction of the transport surface 12a,
As described above, when the improved soil is transported in a state in which the vicinity of the center of the transport surface 12a in the width direction is high in the shape of a mountain, the resistance acting on the mountain portion of the improved soil increases, and the resistance to the outer side in the width direction of the transport surface 12a is increased. In addition to promoting the breaking of the mountains, the scraper 61 is relatively sparsely arranged on the outer side in the width direction of the transfer surface 12a, so that the improved soil moved from the vicinity of the center can pass smoothly without damming, The improved soil can be more uniformly arranged in the width direction of the transport surface 12a.

In the modified examples of FIGS. 19 and 20, the scrapers 61, 61A are conveyed to a position on the upstream side in the conveying direction of the crusher above the conveying belt conveying surface described in the claims. In addition to forming a leveling member for leveling the improved soil, a plurality of rod-shaped members provided substantially perpendicular to the transport surface of the transport belt are also configured so as to level the improved soil to be transported.

As described above with reference to FIG. 1, in the above, the conveyor 1 of the grain refiner is provided with the rotating shaft 46 provided on the upstream side in the conveying direction (right side in FIG. 1) as a fulcrum. Although a structure in which the hydraulic cylinder 49 provided on the downstream side in the transport direction (left side in FIG. 1) can be tilted in the transport direction by expansion and contraction is used, the support structure of the transport conveyor 1 is not limited to this, and does not deviate from its technical idea. Various modifications are conceivable. Hereinafter, modified examples will be sequentially described with reference to the drawings.

FIG. 21 is a view showing a modification of the support structure of the conveyor 1 applied to the grain refiner of the present invention.
FIG. Further, the same parts as those in FIG. 1 are given the same reference numerals, and description thereof will be omitted. This modified example is an example in which the transport conveyor 1 is tilted using a four-bar rotating mechanism. In FIG. 21, reference numeral 62 denotes an arm,
Similarly to the case 9, both ends are rotatably connected to the brackets 43 and 48 by pins 50 and 51, respectively.

The support 63 is fixed to the lower part of the conveyor frame 3 in the conveying direction upstream (right side in FIG. 21) from the center of the conveyor frame 3 in the longitudinal direction (horizontal direction in FIG. 21) by, for example, welding. A support plate substantially similar to the plate 47,
Reference numeral 64 denotes a bracket substantially similar to the bracket 48 fixed to, for example, welding at both ends of the support plate 63 in the longitudinal direction (perpendicular to the paper surface in FIG. 21), and 65 is fixed to the frame 41 by, for example, welding. The bracket is substantially the same as the bracket 43. Reference numeral 66 denotes an arm having a shorter length than the arm 62. Like the arm 62, both ends thereof are provided with brackets 64, 6 respectively.
5 is rotatably connected by pins 67 and 68.

Reference numeral 69 denotes a support plate substantially similar to the support plate 47 fixed at a lower portion between the support plates 47 and 63 of the conveyor frame 3 by, for example, welding, and 70 denotes a longitudinal direction of the support plate 69. (In the direction perpendicular to the plane of the paper in FIG. 21) The bracket 48 fixed to the lower portion of both ends by, for example, welding
A bracket 71 substantially the same as that described above is a bracket fixed on the frame 41 by, for example, welding or the like. A hydraulic cylinder 72 has both ends rotatably connected to brackets 70 and 71 by pins 73 and 74, respectively.

The other structure is the same as that of the above-described position embodiment, that is, in this modification, the hydraulic cylinder 7
21 by slightly expanding / contracting the conveyor 2 slightly.
The transport conveyor 1 tilts in the transport direction while moving in the middle and left and right directions.

FIG. 22 is a view showing another modification of the support structure of the conveyor 1 applied to the grain refiner of the present invention, and corresponds to FIG. Further, the same parts as those in FIG. 1 are given the same reference numerals, and description thereof will be omitted. This modified example is an example in which the conveyor 1 can be tilted manually without using power. As shown in FIG. 22, the conveyor frame 3 is rotatable about the rotation shaft 46 as a fulcrum on the upstream side in the transport direction of the transport conveyor 1 (right side in FIG. 22) with the same structure as in the above-described embodiment. Supported.

In this modification, the support plate 4
7 and a plurality of brackets 48 are provided below the conveyor frame 3 on the downstream side (in the left side in FIG. 22) of the conveyor 1 in the conveying direction (three sets in this example), and each bracket 48 inserts and removes the pins 50. By doing
Similar to the modification described above with reference to FIG. 21, the structure can be connected to the bracket 43 via the arm 62.

That is, in this modified example, the end of one side (upper side in FIG. 22) of the arm 62 is connected to an arbitrary one of the above-mentioned brackets 47, so that the inclination angle of the transport conveyor 1 is increased. Has a structure that can be changed step by step.

Reference numeral 75 denotes a handle, which is designed so that the inclination angle of the conveyor 1 can be manually changed, for example, manually by using some tool or tool while ensuring safety. Also, this handle 75 is used as a suspension pipe,
For example, the inclination angle of the conveyor 1 can be changed by a construction machine such as a hydraulic shovel or a crane.

As described above, as long as the basic effect of the present invention, ie, the effect of improving the crushability, can be obtained, the conveyor 1 may have a fixed structure without being tiltable. FIG. 23 is a view showing still another modification of the support structure of the conveyor 1 applied to the grain refiner of the present invention, and is a view corresponding to FIG. In addition, the same parts as those in FIG. 1 are given the same reference numerals, and description thereof is omitted. In FIG. 23, reference numeral 76 denotes a support arm, and its lower end is fixed to the upper left end of the frame 41 in FIG. The upper end of the support arm 76 is, as in the above-described one embodiment, mounted on the lower side of the conveyor frame 3 in the transport direction of the transport conveyor 1 (the left side in FIG. 23) via a bracket 48 provided via the support plate 47. They are connected by pins 50. Further, the upstream side (the right side in FIG. 23) of the conveyor frame 3 in the transport direction of the transport conveyor 1 is supported by the same structure as that of the above-described embodiment by the rotation shaft 46 being held by the holder 44. .

With such a structure, in this modification, the conveyor 1 is provided fixed to the frame 41.

In this modification, the conveyor 1 is fixed to the frame 41 via the pins 50 and the rotating shaft 46. However, the fixing structure is not limited to this, and all the members are welded without using pins or the like. It may be configured to be fixed by bolting or the like. Further, the frame 41 is provided as a base of the transport conveyor 1, but the present invention is not limited to this. For example, a support post or the like is firmly provided at a lower portion of the conveyor frame 3 downstream of the transport conveyor 1 in the transport direction, and The conveyor 1 may be fixed on the ground as it is, and the point is that the conveyor 1 is fixed so as to be inclined upward toward the downstream side in the transport direction.

The same effects can be obtained by applying the above-described modifications of the support structure of the conveyor 1 to the grain refiner of the present invention.

In the above, it is needless to say that the above-described various blades, scrapers, and the support structure of the conveyor 1 can be applied to the granulating apparatus of the present invention in any combination. Of course, a structure in which a plurality of the above-described various blades and scrapers are provided in a single grain refiner may be employed.
When the improved soil is intentionally or consequently conveyed so as to form a mountain on one side (one side) in the width direction of the conveying surface 12a of the conveying conveyor 1, for example, the blades 53Da, 53Db, 53Ea, and 53Eb are used. The blade for moving the improved soil to one side (the other side) in the width direction of the transport surface 12a may be used alone, or the scraper 61 may be used.
May be densely arranged around the above-mentioned mountain (one side) and sparsely arranged in other parts (the other side). Further, in the example described with reference to FIGS. 1 and 21, the transport conveyor 1 is tilted by the expansion and contraction of the hydraulic cylinders 49 and 72, but another expansion and contraction mechanism such as a turnbuckle may be applied. In these cases, a similar effect can be obtained.

In the above description, the chopper 2 is configured to be detachable from the conveyor frame 3, but may be fixed. Further, in each of the rows A to D in which the distal end portion 28b of the cutter 28 is divided by the arrow C in FIG. In the above, the array is bent to the other side in the direction of the rotating shaft 17, but the present invention is not limited to this. For example,
In each row of mosquitoes, an adjacent row may be alternately bent in the opposite direction. In other words, among the cutters 28 attached to the rotating body 26, one that is bent to one side as described above,
If about half of the curved soil is disposed on the other side, the improved soil that has passed through the chopper 2 and has been crushed will be transferred to the transport surface 1.
It is possible to suppress the bias on one side in the width direction on 2a.

Further, in the above, since the brackets 27 having a substantially square shape are used and the adjacent brackets 27 are fixed to the rotating shaft 17 by being shifted by 45 ° from each other, the rows of the cutters 28 in the direction of the rotating shaft 17 are arcuate. However, for example, the number of rows of the cutters 28 can be arbitrarily determined by displacing the adjacent brackets 27 at different angles other than 45 ° from each other and making the shape of the brackets 27 a polygon other than a square. Can be changed. Further, the number of mounting brackets 27 and the mounting pitch in the direction of the rotating shaft 17 are not limited to the configuration described above. In these cases, similar effects can be obtained.

[0098]

According to the present invention, a leveling member is provided at a position on the upstream side in the transport direction of the crusher above the transport surface of the transport belt of the transport conveyor constituting the grain refiner.
For example, even when the improved soil is conveyed in a state of a mountain having a high height near the center in the width direction on the conveyor belt of the conveyor, even if the mountain is leveled, the improved soil extends over substantially the entire length of the conveyor belt in the width direction. Can be arranged substantially uniformly. As a result, the load biased to the cutter near the center in the width direction of the conveyor can be evenly distributed to the cutter arranged outside the width of the conveyor, and the dewatered cake and the soil improvement material are mixed and roughly crushed. Since the improved soil generated as a result can be efficiently crushed, the crushability can be improved.
