DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll shaft type crusher that can be suitably used for crushing tiles and the like.

[0002]

2. Description of the Related Art A conventional roll-shaft crusher for crushing tiles, concrete waste, etc., mainly uses a striking member attached to a roll shaft to collide with a material to be crushed or hitting the material to be crushed. Crushing is performed. There is also a crusher of a type in which an object to be crushed collides with a reaction rod to crush the object. In the conventional crusher as described above, especially in the crusher for tiles,
The main purpose is to crush the crushed material to a particle size suitable for disposal.

[0003] As a crusher for efficiently crushing a plate-shaped object to be crushed, a hammer mill for feeding the plate-shaped object to be crushed one by one into an apparatus and crushing the same is also known.

[0004]

However, when a plate-shaped object such as a tile is crushed by a conventional crusher using a reaction rod, for example, the object to be crushed lies on the side of the reaction rod. And
There is a problem that the crushed object does not accurately collide with the reaction bar and crushing is not effectively performed. In addition, not only a plate-shaped object to be crushed but also a conventional roll-shaft crusher does not always crush the object to be crushed by one collision. In addition, the size of the object to be crushed by a single collision is generally too large, so that it is necessary to collide many times, which is inefficient. Hammer mills for crushing plate-like materials are
The operator has to send the objects to be crushed one by one into the crusher, and the work efficiency is poor. Also, hammer mills are not suitable for crushing small, uneven plates, such as roof tiles.

[0005] Considering that tiles are crushed and reused, if the tiles are crushed to an appropriate grain size, they can be used as raw materials (aggregate) for mortar and roof nanban plaster, or as laying sand and untuckers. It can be suitably reused. However, tiles crushed by a conventional crusher have too large a grain size, so they are unsuitable for reusing them, and are usually disposed of. Alternatively, in order to make this a reusable grain size, the primary crushed material at the construction site is transported to a factory etc. and further crushed by a huge crusher,
It takes time and effort.

The present invention has been made to solve these problems, and an object of the present invention is to efficiently and finely crush and pulverize a crushed object such as a roof tile and to design a crusher compactly. Accordingly, it is an object of the present invention to provide a structure of a roll-shaft crusher that can easily be transported to a construction site, can easily operate the crusher, and can effectively reuse waste.

[0007]

To achieve the above object, the present invention comprises the following arrangement. That is, a housing provided with an input port for the crushed object at the upper part and a discharge port at the lower part, and a rod-shaped projection provided between the input port and the discharge port and supporting the crushed object on the outer peripheral surface. The housing is separated from the roll shaft, and substantially parallel to the axial direction of the roll shaft, for crushing an object to be crushed between the plurality of roll shafts erected radially and the protrusions. And a driving device for rotating and driving the roll shaft.

[0008] The present invention is also characterized in that a plurality of sets of a plurality of projections are provided upright in the longitudinal direction of the roll shaft in a circumferential direction of the roll shaft. Accordingly, the plate-like crushable object such as a roof tile is sandwiched between the rod-shaped protrusions and supported so as to stand in the radial direction of the roll axis, and thus easily collides with the reaction force rod.

[0009] Further, a plurality of the roll shafts are provided. Thereby, the amount of crushing per unit time increases.

[0010] Further, the two shafts are arranged so that their axes are substantially parallel to each other, and the opposing surfaces rotate toward the discharge port. One reaction force is provided above the opposing surfaces of the two roll shafts. A bar is provided. Thus, the crusher can be designed to be smaller than when a reaction force bar is provided for each of two roll shafts. In addition, as the two roll shafts rotate inside toward the discharge port, the material to be crushed is smoothly introduced into the crushing mechanism.

[0011] Further, the roll shaft is located on the loading port side,
Rotary wings for introducing the crushed material between the projections are provided. Thus, the crushed material that is idle around the input port without being sandwiched between the projections of the roll shaft can be sandwiched between the projections of the rotating shaft.

[0012] Further, it is located on the discharge port side of the roll shaft,
A pair of pressing blades for crushing and crushing the crushed object is provided. Alternatively, a second roll shaft in which a plurality of rod-shaped protrusions which are positioned on the discharge port side of the roll shaft and support the object to be crushed and are erected radially on the outer peripheral surface, A second reaction rod fixed to the housing, separated from the second roll axis and substantially parallel to the axial direction of the second roll axis, for crushing the object to be crushed, A drive device that is the same as or separate from the drive device that drives the second roll shaft to rotate is provided. Thus, the crushed object crushed by the roll shaft type crushing mechanism described in claim 1 can be further finely crushed.

Further, a mechanism is provided at the discharge port for separating the crushed material according to the particle size. As a result, it is possible to perform reuse or disposal according to the particle size of the crushed object.

Further, a soundproof material is attached to the outer periphery of the housing. Thereby, noise to the surroundings can be suppressed.

The crusher can be designed compact by arranging the primary crushing mechanism and the secondary crushing mechanism vertically. Moreover, since the crushing can be performed effectively by sandwiching the crushed object between the rod-shaped protrusions, it is possible to obtain a sufficient processing capacity even if the whole is downsized.

And 16b rotate toward the outlet side. Further, by rotating the roll shaft 16a, the rotary blade 18 rotates.

Next, the structure of the secondary crushing mechanism B will be described. 30a is the inside of the housing 2 and the roll shaft 16
a, a pressing blade base fixed below the 16b. The pressing blade base 30a is attached to the side surface of the housing 2 below the roll shaft 16b in a form projecting in a chevron toward the center of the housing 2. Reference numeral 30b denotes an upper end supported by a shaft 34 on a side surface of the housing 2 opposed to the pressing blade base 30a, whereby the lower side of the pressing blade base 30b can swing. In the lower half of the pressing blade bases 30a and 30b, a crocodile tooth pressing blade 32 is provided.
a and 32b are provided. The pressing blades 32a and 32b are provided so as to mesh with each other by swinging the pressing blade base 30b. Pressing blade base 30a is angled, pressing blade base 30
b is formed in a flat shape, so that a portion (a) sandwiched between the upper half of the pressing blade base 30a and the upper half of the pressing blade base 30b receives the crushed material and introduces it downward. ), And the part (b) serves as a pulverizing unit for further pulverizing the material to be crushed.

A base end of the crankshaft 38 is supported by a shaft 44 on a side surface of the pulley 42. Crankshaft 3
The tip of 8 is pivotally supported by a shaft 40 on the rear surface of the pressing blade base 30b. The pulley 42 is driven to rotate by rolling an annular belt 80 around a pulley 72 and a pulley 42 attached to an output shaft of the gasoline engine 70. With the above configuration, when the pulley 42 rotates, the pressing blade base 30b swings, and the crushed object dropped from the primary crushing mechanism A is crushed by being sandwiched between the pressing blades 32a and 32b and falls downward. Will be. When the particle size after crushing of the material to be crushed by primary crushing is too large compared to the particle size at the time of reuse, by providing a secondary crushing mechanism in this way, the particle size suitable for reuse etc. It is possible to do.

Next, the configuration of the crushable material separating mechanism C will be described. Reference numeral 56 denotes a rectangular box-shaped sieve. The sieve 56 has an open top surface, one open side surface, and a net on the bottom surface. The mesh of the bottom is coarser near the open side and finer near the open side. The sieve 56 is provided on the fall path of the crushed object below the crocodile-shaped pressing blade of the secondary crushing mechanism. Sieve 5
The finer mesh of the mesh on the bottom surface of No. 6 is located closer to the falling point of the crushed material from the secondary crushing mechanism. Two opposing sides of the bottom surface that are in contact with the unopened opposing side surfaces of the sieve 56 are supported by rails 60 that are horizontally protruded from the opposing internal side surfaces of the housing 2 and can move in the horizontal direction. ing. The crankshaft 54 includes a shaft 58 provided on one side surface of the sieve 56 and a pulley 50
Is formed on a shaft 52 provided on a surface deviated from the center of the shaft, and forms a crank that swings a sieve 56.

With the above configuration, the sieve 56 vibrates simply in the horizontal direction when the pulley 50 rotates. As a result, the crushed material that has dropped from the secondary crushing mechanism B moves on the sieve 56 from a finer mesh to a coarser mesh, and is separated into large particles.

Next, means for transmitting the driving force to each of the A, B, and C mechanisms will be described. The transmission of power to the secondary crushing mechanism B is performed by the engine 7 as a power source as described above.
This is performed by fixing the pulley 72 to the output shaft of No. 0 and wrapping the annular belt 80 between the pulley 72 and the pulley 42.

This is performed by hanging the annular belt 20 on a pulley fixed to the base end of the roll shaft 16a. Since the configuration of the primary crushing mechanism A is as described above,
a, 16b, and the rotating wings 18 rotate.

Next, transmission of power to the sorting mechanism C will be described. An annular belt 88 is stretched over a pulley fixed to the base end of the rotating roll shaft 16b and a pulley 86 rotatably supported at both shaft ends. Further, the annular belt 90 is stretched over the pulley 86 and the pulley 50 described above. With the above configuration, the pulley 50 rotates, and the sieve 56 vibrates in a simple manner due to the configuration of the sorting mechanism C described above.

The gasoline engine 7 as a drive source
0 is not limited to gasoline engines, electric motors, etc.
Any device that can provide the driving force may be used.

On the outer periphery of the housing 2, a glass wool decorative insulation plate (not shown) is attached as a soundproofing material.
This makes it possible to reduce noise to the surroundings during operation of the crusher.

The roll shaft type crusher of the present embodiment is characterized by the structure of the roll shafts 16a and 16b so that a plate-like body such as a tile can be crushed reliably and efficiently. FIG.
FIG. 4 is an explanatory diagram showing an enlarged configuration of the roll shafts 16a and 16b. FIG. 3 is a front view of the roll shaft 16. The roll shaft 16 is formed by erecting a projection on the outer peripheral surface. The protrusions are arranged radially when viewed from the axial direction. The reason why the protrusions are arranged at intervals is to crush the object to be crushed between adjacent protrusions. Further, in order to make it easier for the plate-shaped crushed object to be caught between the projections, a plurality of sets of a plurality of projections fixed side by side in the longitudinal direction of the roll axis are provided in the circumferential direction of the roll axis. Can be

As a result, a plate-like crushed object such as a tile is
Since it is sandwiched between the rod-shaped projections and supported so as to stand in the radial direction of the roll axis, it is easy to reliably collide with the reaction force rod, and the crushing efficiency is improved. In particular, plate-shaped or rod-shaped objects to be crushed, which had poor crushing efficiency with a conventional roll-shaft crusher,
By standing in the radial direction of the roll axis, the crushing efficiency can be dramatically increased. In addition, by sandwiching the object to be crushed between the rod-shaped protrusions, the particles are crushed by a single collision to a particle size substantially determined by the distance from the surface of the roll shaft to the reaction force rod, so crushing efficiency is improved. Become a target. In addition, if the size of the crushed object crushed by one collision with the reaction rod is large, the crushed crushed object will fit between the next rod-shaped projections, and if it is small, it will fall down, so The grain size of the object tends to be constant. In addition, since the shape of the protrusion attached to the roll shaft is rod-shaped, the object to be crushed is less likely to escape or shake from side to side when colliding with the reaction rod.

There is a suitable arrangement of the projections depending on the shape of the object to be crushed. For example, when the object to be crushed has a rod-like shape, the protrusions are erected at small intervals so that the rod-like object to be crushed stands radially on the surface of the roll shaft. In this embodiment, as shown in FIGS. 2 and 3, a set of rod-shaped protrusions is provided at regular intervals in the axial direction in order to effectively crush a plate-like crushed object (roof). And a plurality of such sets are assembled in the circumferential direction of the roll shaft. By doing so, the plate-like crushed object is sandwiched between the sets of protrusions adjacent in the circumferential direction while standing in the radial direction of the roll axis.

In the present embodiment used for crushing roof tiles, the length of the rod-shaped blade 26 is about 50 mm, the diameter is about 10 to 20 mm, the diameter of the roll shaft 16 is about 160 mm, and a set of circumferential projections is as follows. There were 12 sets at equal intervals. The arrangement and number of the projections can be set as appropriate.

As shown in FIG. 2, two roll shafts (16a,
16b) By providing, the crushing becomes efficient. In addition, by rotating the rotation directions of the two roll shafts so that the mutually facing surfaces of the roll shafts move downward, one corresponding reaction force rod is sufficient.

The rotary wing 18 shown in FIG.
8a. The longitudinal direction of the rotation axis of the rotating wing 18 and the longitudinal direction of the planar wing 18a are substantially parallel to each other, and each of the plate-like wings 18a forms an angle of 90 degrees when viewed from the longitudinal direction of the rotating shaft. It is erected. The rotation of the rotary wings 18 causes the projections 2 on the roll shaft 16 to lie horizontally in the vicinity of the hopper above the roll shaft 16 and lie on the hopper.
It is possible to stir the crushed material that is rotating without being vertically sandwiched between the protrusions 6 and to be sandwiched between the protrusions 26. By this mechanism, the tile is smoothly introduced into the primary crushing mechanism without bothering the operator.

FIG. 4 shows another example of the configuration of the roll shaft. In this example, the protrusions 26 on the roll shaft 16 are spirally arranged with respect to the axial direction of the rotating shaft 16. Thus, the object to be crushed can be gradually broken without contacting the object to be crushed at once with the reaction bar.

Next, the operation of the present embodiment will be described. In FIG. 1, when an object to be crushed, for example, a tile, is put into the hopper while the engine 70 is running, the tile is guided to the inclined surface of the hopper side or directly, the roll shaft 16a of the rear portion A of the primary crusher, Reach the top of 16b. Since rod-shaped protrusions are radially arranged on the roll shafts 16a and 16b in a row in the axial direction of the roll shaft, the roof tiles are arranged between the rows of the protrusions in the radial direction of the roll shaft 16. Stand and fit. Some of the inserted roof tiles may not fit between the protrusions and may be idle in the vicinity of the center between the roll shafts 16a and 16b while lying horizontally. These tiles are agitated by the plate-like wings of the rotating wings 18 and are lifted at one end to fit between the protrusions.

The tile sandwiched between the projections on the roll shafts 16a and 16b rotates together with the roll shafts 16a and 16b,
The portion protruding outside of the projection will collide with the reaction force rod 14. The roof tile is sandwiched between the projection and the reaction rod 14, and is broken by the rotational force of the rotating shafts 16a and 16b. At this time, the tile has a substantially constant size determined by the distance from the surface of the rotating shafts 16a and 16b to the reaction rod 14.
Since the particles are crushed by one collision, the crushing efficiency is higher than that of a conventional roll-shaft crusher in which the size of particles crushed by one collision is undefined.

The tile crushed by the roll shafts 16a and 16b and the reaction rod 14 falls onto the upper part of the secondary crushing mechanism B. As described above, the portion A of the secondary crushing mechanism B has the opposite side surfaces inclined toward the inside of the housing due to the shape of the pressing blade bases 30a and 30b. , 32b. By converting the rotation of the pulley 42 into a reciprocating motion using the crankshaft 38 and swinging the pressing blade base 30b, the pressing blades 32a and 32b
Perform opening and closing movements. The roof tiles in the part a are the pressing blades 32a, 3
When the space between 2b is opened, it falls in the middle, and when closed, it is crushed and further crushed.

The tile crushed at the position B of the secondary crushing mechanism B falls onto the sieve 56 of the sorting mechanism C. As described above, the falling point of the object to be crushed by the secondary crushing mechanism is
Since the sieve 56 vibrates, the fine particles having a large particle size in the crushed material first fall below the sieve 56. The sieve 56 of the sorting mechanism C
Because of the simple vibration in the horizontal direction, the material to be crushed is
Move up horizontally. Since the mesh of the bottom of the sieve 56 becomes coarser as the distance from the secondary crushing mechanism increases, the size of the crushed material gradually decreases from the smaller one.
6 fall through the mesh of the screen, and those larger than the mesh will fall down from there when reaching the open side of the sieve 56. In this way, the crushed material to be crushed can be separated according to the grain size.

FIG. 5 shows another embodiment of the roll shaft type crusher. In this embodiment, the roll shaft 1 of the primary crushing mechanism E is used.
There is only one 6c. The secondary crushing mechanism F has the same principle as the primary crushing mechanism E, but the reaction force rod 14b and the roll shaft 1 are arranged so that finer crushing is possible.
The distance of 6d is shorter than that of the primary crushing mechanism E. Further, the distance between the bar-shaped blades 26b as bar-shaped protrusions is
It is made narrower than that of the primary crushing mechanism E. As shown in FIGS. 3 and 4, the protrusions on the outer peripheral surface of the roll shaft 16d are formed by combining a plurality of sets of protrusions erected in the longitudinal direction of the roll shaft in the circumferential direction of the roll shaft. A plurality of sets may be provided. Further, the outer peripheral edge of the plate 28 is formed so that the inner surface of the semi-cylindrical plate 28 having a large number of holes having a diameter of about several millimeters formed along the outer periphery of the roll shaft 16d below the secondary crushing mechanism F. Body 2
When fixed to the inner periphery of the crushed material, the material to be crushed can be crushed to a substantially specific grain size. Since the primary crushing mechanism E has only one roll shaft 16 as compared with the primary crushing mechanism A in FIG. 1, it can be designed to be smaller. Further, the secondary crushing mechanism is for crushing the crushed object crushed by the primary crushing mechanism more finely, similarly to the secondary crushing mechanism B of FIG.

As described above, the secondary crushing mechanism for finely crushing the crushed object crushed by the primary crushing mechanism is based on a pressing blade such as the secondary crushing mechanism B in FIG. 1 and the secondary crushing mechanism in FIG. According to the same principle as the primary crushing mechanism, such as crushing mechanism F,
Alternatively, it is conceivable to select from various variations according to the type of the crushed material and the size suitable for reuse, such as those using a stone mill type mechanism. Alternatively, the secondary crushing mechanism may not necessarily be provided as long as sufficiently fine particles can be obtained by crushing by the primary crushing mechanism.

FIG. 6 shows an example in which a slope is provided as another example of the structure of the above-described sorting mechanism. FIG. 6 is a side sectional view of a crusher in which the sorting mechanism C shown in FIG. Reference numeral 108 denotes a net slope including a square net and a plate attached along two opposing sides of the net to prevent the crushed object from falling off the side of the net. The above-mentioned plate surface is attached obliquely to the horizontal direction on the opposing side surfaces of the housing 2 with the net surface facing down. Further, the net slope 108 is attached such that the upper end portion of the net slope 108 is located on the fall passage of the object to be crushed from the secondary crushing mechanism.

Reference numeral 110 denotes an iron plate slope composed of a square iron plate and plates attached along two opposing sides of the iron plate to prevent the crushed object from falling off the side of the iron plate. The iron plate slope 110 is the net slope 108.
And attached to the opposing side surfaces of the housing 2 with the plate of the net slope 108 at an angle inclined with respect to the horizontal direction in a direction opposite to the net slope 108 with the surface of the iron plate facing down. The magnets 102 and 106 are attached to the lower part of the net slope 108 and the lower part of the iron plate slope 110, respectively.

With the above configuration, the crushed material that has fallen from the secondary crushing mechanism B falls on the upper portion of the net slope 108, and the material that has passed through the mesh of the net slope 108 is placed on the iron plate slope 110, Anything that does not pass through the eye will fall from the lower end of the slope. On the other hand, the crushed material dropped on the iron plate slope 110 is the iron plate slope 11.
It slides on zero and falls from the lower end of the slope.
Thus, the material to be crushed can be separated according to the grain size. According to this mechanism, the material to be crushed can be quickly separated into two-stage grain sizes. Also, the magnet 102,
With 106, metals mixed into the crushed object can be attracted and the metals can be removed, and the crushed object after crushing can be easily reused or disposed.

When the tile was actually crushed using the tile crusher of the present embodiment, the tile was crushed to a diameter of about 30 by the primary crushing mechanism.
It was crushed to about 40 mm. Next, it was crushed by a pressing blade of a secondary crushing mechanism into particles having a diameter of about 2 mm to 3 mm. For the purpose of landfill and other disposal purposes, the size of primary crushing is sufficient, but by secondary crushing,
It could be efficiently crushed to a grain size (approximately 2 mm to 3 mm in diameter) that could be reused as raw material for nanban plaster, mortar, untucker, and litter.

Since a tile has a property of absorbing water as compared with sand and gravel, it can be suitably used as a raw material (aggregate) for mortar and nanban plaster if crushed to an appropriate grain size. . According to the crusher according to the present invention, as described above,
Tiles can be finely crushed so that they can be reused with a single crusher, and sufficient processing capacity can be obtained even if the size is reduced. Therefore, as shown in Fig. 7, the crusher is mounted on a truck bed and transported. It is also possible. In fact, at the time of filing the present application, the present inventor has actually confirmed that the tile crusher according to the method of the present invention can be carried by a 2t truck. Furthermore, if the components of the crusher are optimally miniaturized, it can be transported by light trucks.

By using a crusher that has become easier to transport, a tiler can transport the tile crusher to a construction site and crush the tile simultaneously with removing the old tile from the roof. In addition, since the crushed tile can be used on the spot as a raw material (aggregate) for the nanban plaster of the roof, the amount of tile waste to be transported and disposed of is reduced, and the cost and labor for transportation and disposal can be reduced. This has the effect of reducing the cost of purchasing materials.

[0047]

According to the present invention, the object to be crushed can be efficiently and finely crushed, and particularly, the object to be crushed in a plate shape can be effectively crushed. Further, the crushing machine can be designed to be small in size by improving the crushing efficiency. Especially when applied to a tile crusher, the crusher can be easily transported by medium and small trucks, the tile can be crushed at a construction site at one time, and mortar,
It can greatly reduce costs, labor, and waste, as it can produce raw materials for roof nanban plaster, paving sand, and untuckers.
