In a direction substantially perpendicular to the direction in which the clay is conveyed.
Cutting, crushing and discharging on dry sand, the dry sand and the clay
It is characterized by kneading clay crushed by crushing means
It is a mixed soil production method .

[0005] The mixed soil production apparatus according to the above <1> is a dry sand supply means for supplying dry sand, a clay supply means for supplying clay and transporting the clay in a substantially horizontal direction with respect to the ground, and the clay supply means. The clay supplied and conveyed by the clay supply means is disposed in opposition near the downstream end of the clay, and is directly cut in a direction substantially orthogonal to the direction in which the clay is conveyed, and crushed. A clay crusher for discharging the dried clay toward the dry sand supplied by the dry sand supply means, and a kneading method for kneading the dry sand supplied by the dry sand supply means and the clay crushed by the clay crushing means. Means.

[0006] In the mixed soil production apparatus, dry sand is supplied by the dry sand supply means. The clay is supplied by the clay supply means and is conveyed in a substantially horizontal direction with respect to the ground. At this time, the clay supplied and transported by the clay supply means is disposed near the downstream end of the clay supply means.
The clay crusher cuts and crushes the clay in a direction substantially orthogonal to the direction in which the clay is conveyed.
Then, the dry sand supplied by the dry sand supply means and the clay crushed by the clay crusher are kneaded by the kneading means. As described above, a mixed soil in which the dry sand and the clay are kneaded is produced.

[0007] In the mixed soil production apparatus according to the above <2>
Preferably, the clay crusher is rotated, the first cutting blade for cutting the clay, disposed substantially below the first cutting blade, rotated in a direction opposite to the first cutting blade, the first cutting blade A second cutting blade for further cutting the clay cut by the blade. Therefore, in the clay crusher, the clay is firstly cut off by the rotating first cutting blade, and falls as small pieces. At this time, since the second cutting blade is arranged substantially below the first cutting blade, the second cutting blade is located in the falling direction of the small pieces, and is in a direction opposite to the first cutting blade. Is rotating. Accordingly, the clay that falls as small pieces is then cut up by the rotating second cutting blade in an upward direction opposite to the falling direction, further cut into small pieces, and crushed.

[0008] In the mixed soil production apparatus according to the above <3> , the first cutting blade and the second cutting blade are arranged in parallel at equal intervals in the longitudinal direction of the rotating rod member. A set of blade members protruding from the surface of the rod member and fixed to the surface of the rod member in a state where each cutting edge is on the same straight line and oriented in the rotation direction is attached to the rotation axis of the rod member. On the other hand, four sets are provided at equal intervals. That is, the first cutting blade and the second cutting blade are substantially cross-shaped when viewed from the rotation axis direction, the rod member, and the plurality of blade members arranged in a line in the longitudinal direction of the rod member. Are provided at 90 ° intervals with respect to the rotation axis of the rod member. In the set of blade materials, the cutting edge of each blade material is oriented in the same direction. The cutting edges of the blade members in each set are oriented in the rotation direction.

For this reason, in the first cutting blade rotating with respect to the clay, the cutting edge of each blade material comes into contact first, and the second cutting blade rotating in the opposite direction to the first cutting blade also has the following characteristics. The cutting edge of each cutting material comes into contact first, and in any case, does not contact the peak located on the opposite side of the cutting edge first. Clay is cut down into small pieces by each cutting edge of a set of blades (a plurality of side-by-side blades) of the rotating first cutting blade, followed by another set of the first cutting blade. Of each blade material (a plurality of blade materials arranged in parallel) are cut down into small pieces by each blade edge. Thus, the clay is cut into small pieces one after another by the first cutting blade and falls down.

At this time, since the second cutting blade is disposed substantially below the first cutting blade, the second cutting blade is located in the falling direction of the small pieces, and Is rotating in the opposite direction. Therefore, the clay that falls as small pieces is then moved in the direction opposite to the direction of gravity (gravity direction) of the clay in the second cutting blade rotating in the opposite direction to the first cutting blade, that is, from below. The blades of a set of blade materials (a plurality of blade materials arranged in parallel) that move upward are bitten by a strong impact, and immediately thereafter are cut upward to be cut into small pieces and crushed. Subsequently, each of the other set of blade materials (a plurality of parallel blade materials) of the second cutting blade is cut up upward into small pieces by each blade edge,
Crushed. In this way, the clay that has been further cut and fragmented by the first cutting blade is further cut and fragmented by the second cutting blade.

In the mixed soil production apparatus according to the above <4> , since the blade material is a sickle blade, the sickle blade is used in the first cutting blade and the second cutting blade. Each cutting edge and the rotational movement cause each cutting edge to act on the clay like a sickle. That is, the cutting edges of the respective blade members in the first cutting blade and the second cutting blade are not straight but curved. For this reason, the clay is not cut in a straight line, but cut by the curved cutting edge according to the shape of the cutting edge (to a curved shape). Moreover, since the curved cutting edge is rotating, the clay is cut by the rotating and curved cutting edge portion so as to be cut off. For this reason,
Clay is reliably cut regardless of its viscoelasticity or the like.

[0012] In the mixed soil production apparatus according to the above <5> , the rotation axis of the second cutting blade is vertically below and parallel to the rotation axis of the first cutting blade. Since it is located, the clay cut into small pieces by the first cutting blade reliably contacts the second cutting blade. Therefore, the cutting rate of the clay by the second cutting blade is high. As a result, the clay is surely and efficiently fragmented and crushed by the first cutting blade and the second cutting blade.

[0013] In the mixed soil production apparatus according to <6> , the clay is obtained by compressing and filtering the washing water obtained by washing the crushed stone. Such a clay, that is, a clay obtained by compressing and filtering water obtained by washing crushed stone is generally discarded, so that the clay is effectively used as a resource. Moreover, since the clay is almost qualitatively uniform, the clay particles obtained by crushing with the clay crusher are:
It is homogeneous. As a result, products obtained by further utilizing the clay grains, for example, mixed soil and the like are also homogenized.

[0014] In the mixed soil production apparatus described in the above <7>, the dry sand supply means stores and discharges the dry sand, and the dry sand discharged from the dry sand storage means. And a conveying means for conveying the clay, wherein the clay supplying means is a clay storing means for storing the clay and discharging the clay toward the conveying means. In the mixed soil manufacturing apparatus, the dry sand is stored in the dry sand storage means, and is discharged from the dry sand storage means at the time of manufacturing the mixed soil. The dry sand discharged from the dry sand storage means is transported by the transport means. The clay is accommodated in the clay accommodating means, and is discharged from the clay accommodating means toward the transport means during the production of the mixed soil. At this time, the clay discharged from the clay storage means is crushed by the clay crusher.
The pulverized state is supplied to the conveying means. As a result, the transporting unit transports the dry sand and the clay crushed by the clay crusher. The dry sand and the clay conveyed by the conveying means are kneaded by the kneading means. As described above, a mixed soil in which the dry sand and the clay are kneaded is produced.

[0015] In the mixed soil production apparatus according to the above <8>, the dry sand storing means is a hopper, the transporting means is a belt conveyor, and the clay storing means is a hopper. For this reason, the dry sand is stored in the hopper and discharged from the hopper to the belt conveyor. The clay is stored in the hopper and discharged from the hopper toward the belt conveyor. The hopper can easily control the discharge amount, and the belt conveyor can easily control the transport speed, so that the mixing ratio of the dry sand and the clay in the mixed soil to be manufactured can be easily controlled.

[0016] In the mixed soil producing apparatus according to the above <9>, the mixed soil is ground soil, and the mixed soil is
Since it contains the dry sand, it is excellent in drainage.

[0017] In the mixed soil production method according to the above <10>, the dried sand is cut and ground by a clay crusher.
After feeding clay, kneading the said dry sand and clay. Therefore, when the crushed clay is supplied onto the dry sand, the dry sand adheres to the surface of the clay. The dry sand effectively prevents the clay from adhering to devices, equipment, and the like. Then, the clay having the dried sand adhered to the surface is subjected to kneading, so that the dry sand and the clay are easily and uniformly kneaded. As a result, a homogeneous mixed soil is produced.

[0018]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the mixed-soil manufacturing apparatus and mixed soil production method of the present invention will be described in detail.

(Clay Crusher) The clay crusher used in the present invention includes at least a first cutting blade and a second cutting blade, and further includes other members as necessary.

-First Cutting Blade- The first cutting blade is a rotary blade having a function of being rotated to cut clay. The first cutting blade is not particularly limited in its material, shape, structure, size, etc., as long as it has the above function, and can be appropriately selected depending on the purpose. A blade used for crushing or the like is preferably exemplified.

In the first cutting blade, the blade surface is 1
Or two or more. The latter is preferred in terms of the cutting efficiency of the clay. In the former case, the first cutting blade is made of a disk, and the entire peripheral surface of the disk is a blade surface, the rectangular plate is made of one peripheral surface of a blade surface, and a blade material. (For example, a rectangular shape, a bar shape, or the like), and the blade material has one blade surface. In the latter case, an aspect in which one blade material is provided and the edge surface of the edge material is two or more (for example, an aspect in which two or more edge surfaces are formed in a rectangular or rod-shaped edge material) A mode in which two or more blade materials are provided and each blade material has one blade surface (for example, a mode in which one blade surface is formed on each blade material such as a rectangular shape or a bar shape) or 2 Embodiments described above (for example, embodiments in which two or more blade surfaces are formed on each blade material such as a rectangular shape and a bar shape), and the like.
Among these, from the viewpoint of the cutting efficiency of the clay, the above-mentioned or the above-described embodiment is preferable, the embodiment in which each blade surface is oriented in the same direction is more preferable, and the direction is the rotation direction of the first cutting member. Embodiments are particularly preferred.

As a preferred specific example of the first cutting blade, a plurality of bar members to be rotated are juxtaposed at equal intervals in the longitudinal direction, and each blade edge is aligned on the same straight line and is oriented in the rotation direction (rotation axis). When viewed from the direction, each blade edge is located at the same position and is oriented in the same direction), and a set of blade members protruding from the surface of the rod member and fixed to the surface of the rod member is inserted into the rod. An embodiment is provided in which four sets are provided at equal intervals with respect to the rotation axis of the member.

In this preferred embodiment, the number of blade members in the one set of blade members is not particularly limited, and can be appropriately selected according to the length of the bar member, the size of the clay, and the like. . In addition, the one set of blade members is four in total, but the number of sets may be determined in consideration of the cutting efficiency of the clay, and may be three or less, or five or more. However, from the viewpoint of the cutting efficiency of the clay, it is preferable that these sets are provided at equal intervals with respect to the rotation axis. The distance between the blades in the set of blades can be appropriately determined in consideration of the cutting efficiency of the clay, the shape of the blade edge of the blades, and the like.

As a more preferable specific example of the first cutting means, in the preferable specific example, an embodiment in which the blade material is a curved blade such as a sickle blade is exemplified. in this case,
This is advantageous in that the cutting force on the clay is greater than that of a straight edge having the same length.

The rotation speed of the first cutting means is not particularly limited and can be appropriately selected depending on the intended purpose; however, it is usually about 250 to 500 rpm, and 370 to 370 rpm.
450 rpm is preferred, and about 380 rpm is more preferred. If the rotation speed of the first cutting blade is less than 250 rpm, the cutting efficiency of the clay is poor, and if it exceeds 500 rpm, the load of the motor when cutting the clay may be too large. The first cutting blade can be rotated directly or indirectly via a belt or the like by rotation driving means such as a motor.

-Second Cutting Blade- The second cutting blade is a rotary blade that cuts the clay by being rotated similarly to the first cutting blade. As the second cutting blade, the same material, shape, structure, size, and the like as those of the first cutting blade can be used. The second cutting blade may be the same as the first cutting blade,
It may be different.

The second cutting blade is disposed substantially below the first cutting blade. Preferably, the rotation axis of the second cutting blade is vertically below the rotation axis of the first cutting blade. They are arranged so as to be located in parallel. In this case, since the clay cut by the first cutting blade falls in the weight direction, that is, downwards, the probability that the clay comes into contact with the second cutting blade increases, and the clay cutting efficiency is reduced. Is advantageous.

The second cutting blade is rotated in a direction opposite to the first cutting blade. At this time, the second cutting blade can be rotated in the same manner as the first cutting blade, and the rotation speed is not particularly limited and can be appropriately selected depending on the purpose. Usually, the rotation speed is 250 rpm or more. 370
450 rpm is preferred, and about 380 rpm is more preferred. If the rotation speed of the second cutting blade is less than 250 rpm, the cutting efficiency of the clay may be reduced. The rotation speed of the second cutting blade may be the same as or different from that of the first cutting blade, but is preferably higher than the first cutting blade. In this case, the clay can be pulverized in a more fragmented state. Also, even if the rotation speed of the second cutting blade is higher than the first cutting blade, the second cutting blade is different from the first cutting blade because the load when cutting the clay is small. Even if the second cutting blade is rotated at a higher speed than the first cutting blade, the load on the motor is small.

-Other members-The other members are not particularly limited as long as they do not impair the function as the clay crusher, and can be appropriately selected depending on the purpose. Guide means such as a belt conveyor for guiding the clay to the vicinity,
A housing means such as a rack for housing the first cutting blade and the second cutting blade, a case for housing the clay cut and pulverized by the second cutting blade, and the like are included.

The clay to be cut using the clay crusher of the present invention is not particularly limited. For example, a clay obtained by compressing and filtering washing water obtained by washing crushed stones is preferable. This clay is generally disposed of,
When used in the mixed soil manufacturing apparatus and the mixed soil manufacturing method of the present invention described below, it is advantageous in that high quality mixed soil such as ground soil can be manufactured. The clay may be supplied to the clay crusher of the present invention from any direction, but it is preferable that the clay is supplied to the first cutting blade from a substantially horizontal direction with respect to the installation surface of the clay crusher of the present invention. . In this case, even if the small piece of the clay cut by the first cutting blade is blown by the rotational force of the first cutting blade, the direction is the direction of gravity, and the direction in which the second cutting blade is located. Therefore, it is advantageous in terms of the cutting efficiency of the clay.

EXAMPLES Hereinafter, clay pulverizer used in the present invention, as well as per an embodiment of the mixed soil manufacturing apparatus and mixed soil production method of the present invention using clay pulverizer will be described with reference to the accompanying drawings However, the present invention is not limited to these examples.

FIG. 1 is a schematic explanatory view showing an example of a clay crusher used in the present invention. FIG. 2 is a view of the clay crusher shown in FIG. 1 as viewed from above. The clay crusher 1 shown in FIGS. 1 and 2 includes a first cutting blade 10 and a second cutting blade 20.

The first cutting blade 10 has a plurality of blade members 12 attached to a rod member 11 rotated by a motor 15 via a belt 14.
Is fixed, and is rotated by the drive of the motor 15.
The plurality of blade members 12 are arranged in a plurality on the same straight line in the longitudinal direction of the rod member 11 and are arranged at equal intervals. In one set of the blade members 12 arranged on the same straight line, the cutting edge of each blade member 12 is set. 1
Numerals 3 are on the same straight line and oriented in the rotation direction of the rod member 11. That is, when viewed from the rotation axis direction of the rod member 11, the respective cutting edges 13 are in the state of being overlapped at the same position and oriented in the same direction. In this state, one set of blade members 12 protrudes from the surface of the rod member 11 and is fixed to the surface of the rod member 11. The first cutting blade 10 is provided with four sets of blade materials 12 fixed in this manner at equal intervals (90-degree intervals) with respect to the rotation axis of the rod member 11.

The blade member 12 is not a straight blade but a blade whose tip is curved in a sickle shape. For this reason, the cutting shape of the clay by the blade member 12 is substantially L-shaped. In the blade member 12, the sickle-shaped blades are adjacent to each other, and the clay is cut into a number of substantially square pieces by each of these blade edges.

The direction of the clay 5 supplied to the first cutting blade 10 is not particularly limited.
Is substantially horizontal to the installation surface. Here, the clay 5 is conveyed by a belt conveyor 6 and supplied to the clay crusher 1. The rotation direction of the first cutting blade 10 is a direction in which the cutting edge 13 contacts the clay 5 first in each blade material 12, and is a direction in which a small piece of the cut clay 5 is cut down.
That is, in FIG. 1, the direction is counterclockwise.

Therefore, when the first cutting blade 10 comes into contact with the clay 5 and cuts it, each cutting edge 13 in each blade material 12 is cut.
The direction in which the clay 5 is cut is the direction directly below. The small piece of the clay 5 cut by the first cutting blade 10 falls down (in the direction of gravity) so as to be cut off by the first cutting blade 10.

The second cutting blade 20 is arranged so that its rotation axis is located vertically below and parallel to the rotation axis of the first cutting blade 10. The second cutting blade 20 has a structure similar to that of the first cutting blade 20, and a plurality of blade members 2 are attached to a rod member 21 rotated via a belt 24 by a motor 25.
2 is fixed, and is rotated by driving of the motor 25.

The direction of rotation of the second cutting blade 20 depends on each blade material 22.
Is the direction in which the cutting edge 23 comes into contact with the clay 5 first, and is the direction in which a small piece of the cut clay 5 is cut up (toward the first cutting blade 10). That is, in FIG. 1, the direction is clockwise. For this reason, when the second cutting blade 10 comes into contact with and cuts the clay 5, the clay 5 is further finely cut by the respective cutting edges 23 of the respective blade members 22, and the direction in which the clay 5 is crushed is directly above. . The clay 5 cut and refined by the second cutting blade 20 is once jumped up (in the antigravity direction) so as to be cut up by the second cutting blade 20, and is crushed by the impact at that time. And then fall. The clay 5 cut by the second cutting blade 20 is pulverized into fine particles.

FIG. 3 is a schematic explanatory view showing an example in which the mixed soil production method of the present invention is implemented using the mixed soil production apparatus of the present invention. FIG. 4 is a view of the mixed soil production apparatus shown in FIG. 3 as viewed from above.

, A clay crusher 1, a third component supply means 60, a fourth component supply means 70, and a kneading means 80.

The dry sand supply means 40 has a hopper 41 for storing and discharging the dry sand, and a belt conveyor 42 for conveying the dry sand discharged from the hopper 41. In the dry sand supply means 40, the dry sand is stored and stored in the hopper 41 until the mixed soil is manufactured, and is discharged downward from the bottom of the hopper 41 when the mixed soil is manufactured. The dry sand discharged from the hopper 41 and falling downward accumulates on the belt conveyor 42. At this time, the belt conveyor 42 is being driven, and the dry sand moves on the belt of the belt conveyor 42, and when it reaches the end, falls down from there.

The clay supply means 50 has a hopper 51 for accommodating and discharging the clay in a sheet form, and a belt conveyor 52 for conveying the sheet-like clay (cake) discharged from the hopper 51. In the clay supply means 50, the clay is accommodated and stored in the hopper 51 before the production of the mixed soil, and the hopper 51 is produced during the production of the mixed soil.
Is discharged downward from the bottom as a sheet-like cake. The cake discharged from the hopper 51 moves on the belt conveyor 52 and reaches the end. The clay crusher 1 is disposed at the downstream end of the belt conveyor 52, and the clay that has reached there is cut and crushed by the clay crusher 1.
