Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a technique for producing a soil material used in civil engineering, construction, and other fields.

[0002]

2. Description of the Related Art Cobblestone, gravel, sand, silt, clay, and composites thereof are widely known as soil materials constituting soil structures. For natural soil materials, there are various usages such as "used as they are", "selected and used", "processed and used", and "added with improving material". Among them, in the field of civil engineering / construction, "mechanical characteristics (compressibility / consolidation / shear resistance / breaking strength)", "physical characteristics (particle size distribution / water content / specific gravity)", "water permeability", etc. of earth structures In order to meet the predetermined requirements regarding the above, it is not uncommon to add an improving material to the soil material.

As a recent trend in civil engineering and construction work, in-situ solidification treatment for effectively utilizing locally generated earth and sand at the site has been promoted. This means that the labor, cost, and others required for the disposal of locally generated sediment will be reduced and that locally generated sediment will not be generated as waste, so not only will total costs be reduced, but zero emissions of waste will also be achieved. To contribute.

[0004] When a soil structure having the required characteristics is constructed using locally-generated earth and sand (soil material), in many cases, it is inevitable that the locally-generated earth and sand is improved in soil quality. In the classical method for soil improvement, the backhoe, stabilizer, pug mill, vibrating screen, etc. were used to mix the soil and the improvement material, but these are done using electrical and mechanical power. Therefore, it was pointed out that the equipment would require a large amount of money. Particularly with vibrating screens that are likely to cause blockage, the loss time spent to eliminate the screen blockage has also been a cause of work stagnation. Regarding the soil improvement technology, refer to the literature (JP-A-63-217015)
Publication) -Document (JP-A-6-320526)-
It is still being developed as seen in the literature (Japanese Patent Laid-Open No. 10-280471).

Among the above, the technique of the literature is to mix the earth and sand with the improving material, paying attention to the natural fall of the earth and sand conveyed by the belt conveyor. A brief description of only the main points of the technique of the literature is that the mixing damper is constituted by a plate member orthogonal to the center line of the belt conveyor, and a baffle plate or bar is provided in the center of the front surface of the plate member. According to the technique of the literature, the layered material is sheared (dispersed) in the process of colliding with the baffle plate or bar and passing therethrough, and then the material is reassembled. Therefore, the technique of the literature says that the materials are mixed homogeneously by repeating such dispersion and aggregation.

On the other hand, the technology of the literature is also in line with the technology of the literature in that the earth and sand are mixed with the improving material, paying attention to the natural fall of the earth and sand. That is, in the technique of the literature, one group of juxtaposed baffle members is set as one set, and the baffle member columns of each set are provided in the vertical cylindrical body so as to intersect each other with a vertical interval. According to the technique of the literature, when the material collides with each baffle member in a parallel state and passes through the baffle member, the same dispersion / aggregation as described above occurs. Moreover, the upper baffle member row and the lower baffle member row intersect with each other, so that the stirring action of the material further occurs. The technique in the literature is therefore said to mix the materials more homogeneously.

In the technique of the remaining literature, a group of baffle members arranged in parallel and a collision slide plate of an inverted conical ring shape are alternately arranged vertically and provided in a vertical cylinder. As for the baffle member, it is also proposed to use a spring as a part thereof. Also in the technology of the literature, since the material collides with the respective baffle members in the parallel state, the same dispersion / aggregation as described above occurs. Besides, each baffle member vibrates continuously under the impact of the material collision. Therefore, according to the technique of the literature, the material does not adhere to the baffle members, and the baffle members are not clogged with the material. It is said that the technique of the literature also solves the problem described below that is likely to occur in the technique of the literature by such means.

[0008]

The baffles and bars in the art of the literature are fixed and immovable. After the material collides with such a member and breaks, it only passes through these gaps, so that the clods and the like do not collapse sufficiently, and the homogeneity of mixing is also below the expected value. Particularly in the case of locally-generated earth and sand, gravel having an average outer diameter of 200 to 300 mm is frequently mixed, so that the gravel of this type blocks the baffle member and the bar. Restoration of this requires a lot of effort and time. A more serious problem than that is that the baffle members and bars are destroyed by the collision energy of the large-diameter pebbles that fall at high speed under the acceleration of gravity. The damage to the equipment due to this is large, and the amount of damage, including repairs, work stagnation, and others, far exceeds the case of blockage. Moreover, since repair does not lead to destruction prevention, such destruction accidents will occur again. This is also one of the issues pointed out in the literature.

In the technique of the literature, a plurality of sets of baffle members are provided in a vertical cylindrical body so as to intersect each other with a vertical interval. That is, also in the technique of the literature, since each baffle member has a sieving structure with a gap therebetween, there is a possibility that the above-described trouble such as blockage or member destruction may occur.

In the technique of the literature, each baffle member vibrates continuously under the impact of material collision. It is difficult for the material to adhere to or block the vibrating baffle member. However, since the baffle row of this document technique also has a sieve structure such as a lattice or comb teeth, when a gravel larger than the gap between adjacent baffle members falls, it is blocked as in the above-mentioned document technique. May occur. In addition, it cannot be said that the member protection measures against the collision of large diameter gravel are sufficient.

[0011]

[0022]

The soil material mixing and processing unit according to the first to fourth aspects of the present invention is provided with a rotatable baffle plate having a fulcrum portion on the upper end side in the vertical cylinder, and the baffle plate is elastic at the lower end portion. It is elastically supported by the body and inclined. The vertical cylinder also has a material drop opening at a position corresponding to the lower end of the baffle plate.
In such a mixing processing unit, raw materials and additives that are thrown into the cylindrical body from the upper end side and fall freely are collided with the surface (sloping surface) of the baffle plate, fly off, and fall from the material drop port. To do. At this time, the baffle plate vibrates (self-excited vibration) by receiving the collision energy of the raw material and the additive. It is difficult for these to adhere to the vibrating baffle even if it is a raw material or an additive that is moist. Therefore, even in the case where the raw materials and additives continuously fed into the vertical cylinder fall and collide with the baffle plate in sequence, they do not adhere to the baffle plate or deposit and grow. The baffle plate is also supported by the elastic body as described above. With respect to such a baffle plate, the lower end portion thereof can be pushed downward against the elastic body, and by doing so, the diameter of the material dropping port becomes large. Therefore, in the case where the material drop port is blocked by raw materials and additives, when the load of the blockage (weight of raw materials and additives) on the baffle exceeds the supporting force of the elastic body, the lower end side of the baffle is lowered. Is pushed into the material, the diameter of the material drop opening becomes large, and the obstruction naturally falls from the material drop opening with the larger diameter. When the obstruction disappears, the baffle plate returns to its original inclined state by the restoring force of the elastic body. This means that even if the material drop port is blocked, it will be automatically eliminated by the load of the blockage and the skillful movement of the baffle plate. Even when a falling object collides with the baffle plate, the baffle plate rotates against the elastic body to reduce the impact at that time. This is the self-defense function of the baffle against impact. Therefore, the baffle is unlikely to be destroyed. In the mixing processing unit according to the third aspect, in which the protection member according to the fourth aspect is on the fulcrum portion, a large material (gravel or the like) does not collide with the fulcrum portion. This is desirable to protect the fulcrum.

According to a fifth aspect of the present invention, there is provided a soil treatment mixture treatment apparatus in which a plurality of the mixture units according to the first aspect are combined, and a soil matter mixture treatment apparatus according to the sixth aspect of the present invention is claimed. The mixing processing unit according to claim 2 and the mixing processing unit according to claim 3 or 4 are combined. In the apparatus according to the fifth aspect, when the raw materials and the additives sequentially fall and collide with each baffle plate, the raw materials and the additives are agitated and mixed by the repulsive force and vibration of each baffle plate caused by the collision. In the device according to the fifth aspect of the invention, since the baffles are arranged at different positions in the circumferential direction, the raw materials and the additives falling while sequentially colliding with the baffles are also subjected to the swirling action. Since the stirring action of the raw material and the additive is enhanced as a synergistic effect due to the repulsive force, vibration, and swirling of the baffle plate, a homogeneously mixed soil material can be obtained by the apparatus according to the fifth aspect. Also in the apparatus according to claim 6, both materials are agitated and mixed by the baffle plate repulsive force and the baffle plate vibration when the raw materials and the additives drop and collide, but in this case, a pair of vertically adjacent baffle plates are used. Since one of them is V-shaped and the other is inverted V-shaped, raw materials and additives that fall while colliding with each pair of baffles are gathered by both V-shaped baffles or are inverted V-shaped. It is dispersed by both baffles that form a shape. That is, when the apparatus according to claim 6 is used, since the raw material and the additive are homogeneously mixed by the high stirring action due to the repulsive force, vibration, aggregation and dispersion of the baffle plate, the same high quality soil material as above is obtained. can get. Claim 5
-In the apparatus described in 6, the fact that raw materials and additives do not adhere to the baffle plate and that the material dropping port is not blocked is as described in paragraph [0022].

According to a seventh aspect of the present invention, there is provided a soil material manufacturing system in which a pre-stage carrier device and a rear stage soil material manufacturing device are connected to each other. Furthermore, the soil material manufacturing apparatus in this case comprises the apparatus according to claim 5 or 6. Such a manufacturing system performs a series of flow operations from the supply of raw materials and additives to the manufacture of soil material. That is,
The transport device accelerates the raw materials and additives while continuously transporting them in appropriate amounts. Raw materials and additives that have been accelerated to reach the end of the transportation device are introduced into the vertical cylinder of the soil material manufacturing device from here at high speed. Then, the soil material manufacturing apparatus that receives them mixes the raw materials and the additives with stirring as described above to form a homogeneous soil material. In the manufacturing system according to the seventh aspect, a series of line work increases productivity.
Moreover, in the manufacturing system according to claim 7, in which the raw materials and additives are accelerated and charged into the vertical cylinder, since the material accelerated in speed collides with the baffle plate, the impact force received by the baffle plate is increased. Which promotes the mixing of the materials with each other. Therefore, in the manufacturing system according to the seventh aspect, it is possible to obtain a high quality soil material while maintaining high productivity by the high speed mixing process.

The soil material manufacturing method according to claim 8 of the present invention is carried out by using the soil material manufacturing apparatus according to claim 5 or 6. Therefore, the method according to claim 8 also
When producing a high-quality soil material, it is possible to expect the above-mentioned homogeneity of mixing and automatic avoidance of clogging.

According to a ninth aspect of the present invention, there is provided a method for producing a soil material using the soil material production system according to the seventh aspect. Therefore, the method according to claim 9 can also be expected to have the above-mentioned homogeneous mixing property, high-speed processability, and automatic avoidance of clogging when manufacturing a high-quality soil material. In this case, when the transportation speed of the transported material by the transportation device is 100 to 200 m / min, the productivity of the soil material is further enhanced.

The hopper 32 shown in FIG. 2 is a well-known one having an inverted pyramidal cylinder shape or an inverted conical cylinder shape. A flange 33 is formed on the outer periphery of the lower end of the hopper 32. More specifically, when the vertical cylinder 34 of each of the mixing processing units U1, U2, and U3 described later is a rectangular cylinder, an inverted pyramidal hopper 32 is adopted, and the vertical cylinder 34 is a cylinder. In some cases, an inverted conical hopper 32 is used. In those cases, a part of the peripheral wall of the hopper 32 may rise vertically.

First, regarding the parts / members / local parts, the support shaft 53, the mounting plate 61, the protective member 62, etc. all have a length extending over the front and rear walls of the vertical cylindrical body 34, and the plurality of elastic bodies 63, 64 are plate-shaped. It consists of a spring or a bar spring.
On the other hand, at the upper ends of the baffle plates 45 corresponding to the support shaft 53,
For example, as shown in FIG. 7, a hole for penetrating the support shaft is formed by winding a plurality of fulcrum pieces 46 in a round shape.
Therefore, the both baffle plates 45 are joined like a hinge by aligning the respective holes at the upper ends in a straight line and then inserting the support shafts 53 into these holes. The both baffle plates 45 thus combined are supported in a suspended state in the vertical cylinder 34 as shown in FIG. 6 by supporting both ends of the support shaft 53 using the front and rear walls of the vertical cylinder 34. . In this case, each fulcrum piece 46 and the fulcrum shaft 53 are attached to the fulcrum portion 54 of both baffle plates 45.

5 and the mounting plate 61, respectively. Similarly, each of the other elastic bodies 64 is also spaced along the width direction of the baffle plate 45 and is interposed between the back surface of the baffle plate 45 and the right side surface of the mounting plate 61, and both ends of each elastic body 64 are obstructed. Board 4

Elastically supported by 5. As is apparent from FIG. 6, the both baffle plates 45 in this supporting state are inclined with their lower end sides separated from the inner surface of the left wall or the inner surface of the right wall of the vertical cylindrical body 34. Further, the baffle plate 45 is provided between the left wall inner surface of the vertical tubular body 34 and the lower end of the left side baffle 45, and between the right wall inner surface of the vertical tubular body 34 and the right side baffle plate 45, respectively.

In addition, the rod-shaped protection member 62 is arranged directly above the fulcrum portion 54 in the vertical cylinder 34, and is provided over the front and rear walls of the vertical cylinder 34. Matters whose description is omitted regarding the mixing processing unit U3 in FIG. 6 are substantially the same as or similar to the matters already described.

The lower unit U4 illustrated in FIG. 8 also uses the vertical cylindrical body 34 as an outer shell, like the above units. In the case of the vertical cylindrical body 34 in FIG. 8, one of the walls (right wall)
An outlet 65 is cut out at the lower part of the. Exit 65

Are attached at intervals along the width direction of the right wall, and two horizontal rails 68 arranged in parallel with each other are horizontally supported via these brackets 67. Then, the linear members 66 suspended and supported by the horizontal crossbars 68 are arranged in two rows in front of the outlet 65. As an example, each linear body 66 is composed of a chain. This is like goodwill. Therefore, when a falling object collides with each linear member 66, they are freely deformed and the impact at that time is relieved. In the vertical cylinder 34 of FIG. 8, a cover 69 that covers both sides of the outlet 65 integrally projects from the lower portion of the other two walls (front and rear walls), and is formed on the inner surface of the remaining one wall (left wall). Is fitted with a guide wall 70 having a curved or sloped bottom. The curved bottom portion (or the inclined bottom portion), which is a part of the guide wall 70, has a function of guiding the fallen object that has dropped to this point toward the outlet 65 side. In addition, the vibration generator 4 described above is also provided on the outer surface of the bottom of the guide wall 70.
8 is attached.

There is. As another example, there is a unit connection in which the mixing processing unit U3 is on the upper side and the mixing processing unit U3 is on the lower side. In the unit connected in this manner, the baffle plates 45 of the upper mixing processing unit U2 and the lower mixing processing unit U3 face the same direction. Similarly to the previous example, the soil material manufacturing apparatus 31 of FIG. 9 also has the hopper 32 connected to the uppermost mixing processing unit and the lower unit U4 connected to the lowermost mixing processing unit. In the soil material manufacturing apparatus 31 of FIG. 11, when the number of each of the mixing processing units U2 and U3 is one, the number of units used is the minimum. When combining both mixing processing units U2 and U3,
If either or both of these are two or more, the total number of units will be three or more. An example of this case is schematically shown in FIG. That is, in the soil material manufacturing apparatus 31 to which FIG. 12 is referred, the mixing processing units U2 (plurality) and the mixing processing unit U3 (pluralities) are alternately arranged in the vertical direction and connected. Moreover, as can be understood from the direction of each baffle plate 45, the upper second-stage mixing processing unit U3 is circumferentially offset by 90 degrees with respect to the uppermost mixing processing unit U2.・ Bottom mixing processing units U2, U3, U2
Is also deviated by 90 degrees in the circumferential direction with respect to each mixing processing unit immediately above. Also in the soil material manufacturing apparatus 31 of FIG. 12, the hopper 32 is connected to the uppermost mixing processing unit, or the lower unit U is connected to the lowermost mixing processing unit.
4 is connected.

The material unloading device 81 schematically shown in FIG. 1 mainly comprises a well-known large belt conveyor. With reference to FIG. 1, the material unloading device 81 is arranged immediately below the device 31 so that the upper surface of the base end part thereof corresponds to the bottom part of the soil material manufacturing device 31.

The raw material for the soil material in the present invention is one or more selected from mud, soil, sand, gravel, stone, rock, etc., or a mixture or soil of two or more kinds containing mud. Selected from among two or more mixtures containing sand, two or more mixtures containing sand, two or more mixtures containing gravel, two or more mixtures containing stone, two or more mixtures containing rock, etc. It may be more than one.

One of the weakly welded deposits is commonly known as "shirasu".
These are mainly pyroclastic flow deposits, fallen pyroclastic deposits, and their secondary deposits that are widely distributed in southern Kyushu, and are pumiceous or volcanic ash-white. "Shirasu"
Is also one of the special soils that tend to collapse due to rainfall.
In particular, coarse-grained locally-generated earth and sand (eg river bed gravel) generated during construction work for dam dam body construction and other civil engineering and construction work is often used as a raw material for soil material in the present invention. To be

Additives (additives / additives) in the present invention

Carbon-based materials, petroleum-based materials), general waste incineration ash slag, lightweight foam beads for earthwork, granulated slag for earthworks, separation preventive agent (powder, liquid), water, seawater, air, oxygen, neutralization Agents, alkaline gases, acidic gases, etc. can be mentioned. When two or more kinds of raw materials are selected from the above-mentioned various raw materials and they are mixed to produce a soil material, one or two raw materials at that time may be referred to as an additive. The amount of the additive mixed with the raw material is usually equal to or less than that of the raw material.

When the soil material manufacturing system according to the present invention is used to carry out the soil material manufacturing according to the present invention, it is as follows with reference to FIG. 1 and other drawings.

In the material supply apparatus 11 of FIG. 1, one supply section 12 sends out the raw material put into the hopper 13 onto the belt conveyor 22 of the carrying apparatus 21 by the feeder 14, and the other supply section 15 also inside the silo 16. Of the additives in the carrier 2 by the connecting pipe 18 and the feeder 17.
It is sent onto the belt conveyor 22 of No. 1. In the transporting device 21, raw materials and additives are used as the first stage belt conveyor 2
2 to the second-stage belt conveyor 23, and then the second-stage belt conveyor 23 to the third-stage belt conveyor 24
Transfer to. Raw materials and additives are
It can be carried up to a height of about 0 to 30 m, and since the carrying speed is 100 to 200 m / min, the speed is sufficiently increased.

The raw materials and additives to which high potential energy and high speed have been applied by the transporting device 21 fall while being rapidly rushed into the soil material manufacturing device 31 from the belt conveyor 24 at the third stage in FIG. Go. If the soil material manufacturing apparatus 31 in this case is of a type as shown in FIG. 9 or FIG. 10 (A), a plurality of or a plurality of vertical cylinders 34 arranged vertically are provided.
Inside, "Collision to the left baffle 45" → "Right material drop port 6
“Pass 0” → “Collision to right baffle plate 45” → “Pass through left material drop port 60” → “Collision to left baffle plate 45” → “Pass through right material drop port 60” The raw materials and additives reach the lower part of the soil material manufacturing apparatus 31 while following the route. Therefore, in the case of FIG. 9 and FIG. 10 (A) in which the falling objects alternately collide with the baffle plates 45 on the left and right and in multiple stages, disturbing, left-right reversing, shearing and the like are forcibly generated at each collision, and the raw material and the additive are Are mixed homogeneously. On the other hand, in each of the vertical cylinders 34 of the soil material manufacturing apparatus 31 of FIG. 10B, “collision with the rear baffle plate 45” → “pass through the front material drop port 60” → “left baffle” Collide with plate 45 "→
"Passing the right material drop port 60" → "Collising the front baffle plate 45" → "Passing the rear material drop port 60" → "Right baffle plate 4"
5) → “Passes the left material drop port 60” → “Collises the rear baffle 45” → “Passes the front material drop port 60”. 31
Down to the bottom. Therefore, the falling objects sequentially collide with the rear, left, front, and right baffles 45 having different heights.
In the case of 0 (B), disturbance, swirling, shearing, etc. are forcibly caused by these collisions, and the raw material and the additive are homogeneously mixed. On the other hand, the soil material manufacturing apparatus 3 shown in FIGS.
In the case of 1, two types of mixing processing units U2 and U3 are alternately arranged in the vertical direction. In these, the mixing processing unit U2 having the V-shaped baffle plates 45 collects the raw materials and the additives, and the mixing processing unit U3 having the inverted V-shaped baffle plates 45 disperses the raw materials and the additives. That is, during the dropping process, the raw materials and additives gather due to the collision with the V-shaped baffle plates 45, and the inverted V-shaped baffle plates 4 are gathered.
In the collision with 5, the raw materials and additives are dispersed while being sheared. When these are combined, the raw materials and additives are homogeneously mixed by aggregation, dispersion, shearing, or the like. Moreover, in the soil material manufacturing apparatus 31 of FIG. 12, since the V-shaped and inverted V-shaped baffle plates 45 on each stage have their directions different in the circumferential direction, the raw materials and additives that collide with them can be used. Turns also occur. So in this case,
The raw materials and additives are mixed homogeneously by shearing and swirling applied thereto.

In the above, the raw materials and additives that fall freely in the vertical cylinder 34 collide with the inclined surfaces of the baffle plates 45 arranged vertically. At this time, each baffle plate 45 receives the collision energy of the raw material and the additive and vibrates by itself. When it is difficult for raw materials and additives to adhere to the vibrating baffle plates 45, the raw materials and additives that are continuously charged into the vertical cylindrical body 34 sequentially fall and collide with the baffle plates 45. In addition, they do not adhere to the baffle surface or accumulate and grow. As can be understood from this description, there is almost no need to actively vibrate the baffle plate 45 by using the vibration generator 48.

As described above, each baffle plate 45 is rotatable, and the lower side of each baffle plate is elastic body 55, 56, 63 ,.
64 is elastically supported. When a load exceeding the elastic body supporting force acts on the baffle plate 45, the elastic body 55.6
Since the baffle plate 45 rotates downward against the force of 3.64, the diameter of the material drop port 60 becomes large. Therefore, even if the material drop port 60 is blocked with raw materials and additives,
When the load of the obstruction on the baffle plate 45 exceeds a predetermined value, the baffle plate rotation as described above automatically occurs, whereby the diameter of the material drop port 60 becomes large, and the material drop port 60 having a large diameter is generated. The obstruction will fall more naturally. That is, the material dropping port 60 is not constantly closed even if it is temporarily closed. When the obstruction disappears, the baffle plate 45 returns to the original inclined state by the restoring force of the elastic body. Further, each baffle plate 45 elastically absorbs and relaxes the impact even when a falling object collides, so that the destruction thereof is hard to occur. In addition, in the case of FIG. 6, since the protection member 62 is directly above the fulcrum portion 54, the falling object does not collide with the fulcrum portion 54, and therefore the fulcrum portion 54 is protected from damage and destruction.

The mixture of the raw material and the additive which has been mixed and processed as described above becomes a soil material and falls to the lower side of the soil material manufacturing apparatus 31. Since the lower unit U4 having the guide wall 70 inside is located on the lower side of the soil material manufacturing apparatus 31, the soil material that has dropped to the lower side of the apparatus 31 is guided by the guide wall 70 and is discharged from the outlet 6 of the lower unit U4.
5, and falls from here onto the material unloading device 81. The soil material on the material unloading device 81 is now transported to the stockyard.

The soil material produced by the means of the present invention can be finished in a wide variety by selecting the types of raw materials / additives and the compounding ratio. The soil materials exemplified below are some of them. Coarse-grained locally generated earth and sand such as riverbed gravel is used as a raw material, and additives mixed with cement, bentonite, quicklime, etc. are added and mixed to provide an improved soil material when constructing a sabo dam body. Raw materials that contain soft hydrated cohesive soil or gravel,
A soil material obtained by adding and mixing a stabilizer (additive) such as quick lime or cement to this is useful when constructing a stable soil structure. Soil materials containing a large amount of crushed weathered rocks as raw materials are used for civil engineering and construction, such as water blocking materials for rockfill dams, water blocking materials for final landfill sites, and protective materials for waterproof sheet layers. Tensile strength soil material, which is made by adding chemical fiber (short fiber) as an additive to the raw material, is also used to prevent river levee, cut soil, embankment slope, etc. from being eroded by running water or rainwater. It will be for civil engineering. The soil material in which raw wood chips are added as an additive to the raw material and mixed is a vegetation soil suitable for various wood treatment and root removal treatment, and thus can be said to be one for agriculture and forestry. The earth material mixed with crushed shells as an additive becomes a backfill material for earthwork. In the case of soil materials made from cohesive soil blocks such as loam and dredged soil, and stabilizers (additives) such as cement and polymer stabilizers (additives) added to them, earthwork It can be used as a sand mat for drainage as well as a backfill material. Soil material containing coal ash as an additive becomes a filling material for earthwork. A soil material containing a large amount of crushed waste concrete as a raw material can be effectively used as recycled sand. Soil materials made from various sludges containing organic phosphorus and organic compounds as raw materials and additives are suitable for microbial culture as well as aquaculture of earthworms and other small animals. Soil materials used for hatching insects and the like are made to contain appropriate water as an additive. Soil materials made from various gravel soils as raw materials and additives are used as flooring materials for aquaculture (water bottom) and filter materials for water treatment.
The soil material for agriculture is made by including fertilizer (additive).

Referring to the contents described above, when the soil material manufacturing apparatus 31 of the present invention is constituted by the mixing processing unit U1 of FIG. 3, the number of the units is a minimum of two, and the mixing processing unit of FIG. When the soil material manufacturing apparatus 31 is configured using U2 and the mixing processing unit U3 of FIG. 6, the number of each unit is at least one. In the latter case, which unit is placed at the top is free, so when the number of units is three, two types of units are U2U
3. Line up and down in the order like U3, or U
They are lined up and down in the order like 3, U2, U3. For each of the mixing processing units U1, U2, and U3, the outlet 37 may be omitted from the vertical cylinder 34. It is desirable to use the hopper 32 and the lower unit U4 in the soil material manufacturing apparatus 31 that uses any unit, but this is not an essential requirement. Other soil material manufacturing equipment 31
In the above, the vertical cylinders 34 of each unit are vertically connected and integrated. Therefore, in the soil material manufacturing apparatus 31, configuring the series of vertical cylinders 34 with a single cylinder is merely a design change.

In the soil material manufacturing system of the present invention,
The transport device 21 has a plurality of belt conveyors 22, 23, 24
It will be a combination of. Of these, two belt conveyors 22 and 23 convey raw materials and additives to a high level above the ground, but when it is not necessary to convey a conveyed material to such a high level, this type of belt conveyor is one. Good. In addition, when arranging the transportation device 21 and the soil material manufacturing device 31 by utilizing the step of the terrain, for example, when arranging the transportation device 21 on the cliff and arranging the soil material manufacturing device 31 under the cliff, As the device 21, only one belt conveyor 24 is sufficient. At that time, the belt conveyor 2
4 may be arranged horizontally without inclination.

For soundproofing and protection of members, the inner surface and / or outer surface of the vertical cylinder 34 and the front surface and / or back surface of the baffle plate 45 may be lined with rubber or synthetic resin. Specifically, a durable rubber sheet or synthetic resin sheet is attached to the inner and outer surfaces of the vertical cylinder 34, the front and back surfaces of the baffle plate 45, and the like. In this case, the noise generated when the falling object collides with the vertical cylinder 34 or the baffle 45 can be kept low, and these members (the vertical cylinder 3
4. The impact on the baffle plate 45) can also be mitigated. The vertical cylinder 34 has a double wall structure, or each unit U1 to U
Surrounding 4 with a sound insulation wall is also effective as a soundproofing measure. Other elastic bodies 55, 56, 63, 64
For, the high-strength rubber or synthetic resin high-strength material may be used instead of the metal one, or
A rubber or synthetic resin material and a metal material can be used together.

EFFECTS OF THE INVENTION The mixing processing unit for soil material, the soil material manufacturing apparatus, the soil material manufacturing system, and the soil material manufacturing method according to the present invention have the following effects.

The mixing processing unit is for colliding raw materials and additives which fall freely with an inclined baffle plate to mix them. Obviously, the baffle plate is not comb-shaped or lattice-shaped but planar, so that it is not clogged with raw materials and additives. In addition, the baffle that vibrates when a falling object collides with it is unlikely to adhere or accumulate raw materials and additives. The baffle plate is also elastically supported by an elastic body and inclined. Such baffles
When the material dropping port in the vertical cylinder is clogged with a raw material or an additive, the clogged object is dropped by the skillful movement utilizing the load of the clogged object, so clogging in the mixing processing unit is unlikely to occur. Even when a falling object collides with the baffle, the baffle rotates while resisting the elastic body and absorbs the impact at that time, so that the baffle is unlikely to be damaged or destroyed. In addition, the mixing processing unit mixes the raw materials and the additives by utilizing free fall, so that no special mixing energy is required and it is economical. In addition, in the mixing processing unit in which the protection member is on the fulcrum, the falling object does not collide with the fulcrum, and the effect of protecting the fulcrum is high.

The soil material manufacturing apparatus is a combination of a plurality of the above-mentioned mixing processing units. When using such a soil material manufacturing apparatus, raw materials and additives falling in the vertical cylinder fall and collide with each baffle plate one after another, and baffle plate repulsion force / baffle plate vibration at that time and gathering / dispersion of falling objects The raw materials and additives are homogeneously mixed by the high stirring action of these such as turning and shearing. Of course, also in the soil material manufacturing apparatus, the raw materials and additives do not adhere to the baffle plate, and the material drop port is not blocked. Moreover, since a power source for mixing is not required, it is possible to ensure the simplicity and economy of the equipment.

The soil material manufacturing system is a system in which a conveying device in the first stage and a soil material manufacturing device in the second stage are connected to each other, and the process from the supply of raw materials and additives to the production of the soil material is performed in a series of flow operations. You can In particular, with regard to the transportation device, it is possible to accelerate the raw materials and additives while continuously transporting the appropriate amounts of the raw materials and additives, and to inject the accelerated raw materials and additives into the vertical cylinder of the soil material manufacturing apparatus at high speed.
One of the features of such a manufacturing system is that a series of line work increases productivity. As another feature, accelerating the raw materials and additives into the vertical cylinder facilitates mixing of the materials. Therefore, according to the manufacturing system, a high quality soil material can be obtained while maintaining high productivity by the high speed mixing process. Of course, a power source for mixing is unnecessary.

The soil material manufacturing method is carried out using the soil material manufacturing apparatus described above. Therefore, when manufacturing a high quality soil material, the above-mentioned homogeneous mixing and automatic avoidance of clogging are required. Can be expected. In this case, the transportation speed of the transported material by the transportation device is 100 to 2
When it is set to 00 m / min, the productivity of the soil material is further increased.
In addition, the running cost is low because it does not require a power source for mixing.
