Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a roll shaft type crusher which can be suitably used for crushing roof tiles and the like.

[0002]

2. Description of the Related Art A conventional roll shaft type crusher for crushing roof tiles, concrete waste materials, etc. is mainly constructed by hitting a striking member attached to a roll shaft with an object to be crushed or hitting the objects with each other. It is for crushing. There is also a type of crusher that crushes the crushed object by colliding it with a reaction force rod. In the conventional crusher as described above, especially the crusher for roof tiles,
The main purpose is to crush the crushed material to a grain size suitable for disposal.

Further, as a crushing machine for efficiently crushing plate-like objects to be crushed, there is also known a hammer mill for feeding plate-like objects to be crushed one by one into the apparatus for crushing.

[0004]

However, for example, when a plate-shaped object such as a roof tile is crushed by a crusher using a conventional reaction force rod, the object to be crushed lies sideways with respect to the reaction force rod. And
There is a problem that the crushed object does not collide with the reaction force rod accurately, and the crushing is not performed effectively. Further, not only the plate-like object to be crushed but also the conventional roll shaft type crusher does not always crush the object to be crushed by one collision. In addition, since the size of the crushed object that breaks in one collision is generally too large, it requires multiple collisions, which is inefficient. In addition, a hammer mill that crushes plate-like crushed objects,
The worker has to send the crushed objects 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.

Considering that the tiles are crushed and reused, if the tiles are crushed to an appropriate grain size, they are used as a raw material (aggregate) of mortar and nanban stucco for roofs, or as paving sand, antonkers, etc. It can be suitably reused. However, since the tiles crushed by the conventional crusher have too large a grain size, they are not suitable for reuse in them and are usually discarded. Alternatively, in order to make it reusable, the primary crushed material at the construction site should be transported to a factory or the like and further crushed with a huge crusher.
It takes time and cost.

The present invention has been made to solve these problems, and an object thereof is to efficiently crush and crush crushed objects such as roof tiles, and to design the crusher compactly. By doing so, it is an object to provide a structure of a roll shaft type crusher that can be easily transported to a construction site, the crusher can be easily operated, and waste can be effectively reused.

[0007]

In order to achieve the above object, the present invention has the following constitution. That is, a casing having an input port for the material to be crushed in the upper part and a discharge port in the lower part, and an intermediate part between the input port and the discharge port, on the outer peripheral surface in the axial direction

This ensures that the plate-shaped object to be crushed, such as tiles is caught between the rod-like protrusions, to be supported to stand radial direction of the roll axis, it tends to collide fully with the reaction force rod.

Further, a plurality of roll shafts are provided. This increases the crushing amount per unit time.

Further, the axes are arranged so as to face each other substantially in parallel, and the facing surfaces have two roll shafts that rotate toward the discharge port, and one reaction force is provided above the facing surfaces of the two roll shafts. It is characterized in that a bar is provided. As a result, the crusher can be designed smaller than in the case where a reaction force rod is provided for each of the two roll shafts. Further, the two roll shafts rotate inward of the two roll shafts toward the discharge port, so that the crushed object is smoothly introduced into the crushing mechanism.

Further, it is located on the inlet side of the roll shaft,
It is characterized in that a rotary vane is provided for introducing the crushed object between the projections. As a result, the object to be crushed, which does not get caught between the projections of the roll shaft in the vicinity of the charging port, can be caught between the projections of the rotating shaft.

Further, a soundproof material is attached to the outer periphery of the casing. This makes it possible to suppress noise to the surroundings.

The crusher can be designed compact by arranging the primary crushing mechanism and the secondary crushing mechanism vertically. In addition, since the crushed object can be effectively crushed by sandwiching the crushed object between the rod-shaped projections, it is possible to obtain sufficient processing capacity even if the size is reduced as a whole.

A gear 24, which is rotatably supported by the housing 2, is meshed with a gear fixed to each of the base ends 6b and 6b. With the above configuration, the roll shaft 16a is replaced by the roll shafts 16a and 16b.
By rotating the inner surfaces facing each other toward the discharge port side (downward), the roll shaft 16b and the roll shaft 16a also rotate.
The inner surfaces of 16 and 16b facing each other rotate toward the outlet side. Further, by rotating the roll shaft 16a, the rotary wings 18 rotate.

Next, the structure of the secondary crushing mechanism B will be described. Reference numeral 30a denotes an inside of the housing 2 and is provided with the roll shaft 16
It is a pressing blade base fixed below a and 16b. The pressing blade base 30a is attached to the side surface of the housing 2 below the roll shaft 16b so as to project in a mountain shape toward the center of the housing 2. 30b has an upper end pivotally supported by a shaft 34 on a side surface of the housing 2 facing the pressing blade base 30a, whereby the pressing blade base 30b can swing on the lower side. The crocodile tooth-shaped pressing blade 32 is provided on the lower half of the pressing blade bases 30a and 30b.
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. The pressing blade base 30a is chevron, and the pressing blade base 30 is
Since b is formed in a flat shape, the portion a sandwiched between the upper half of the pressing blade base 30a and the upper half of the pressing blade base 30b is an introduction portion (hopper) for accommodating the crushed object and introducing it downward. ), And the part (2) serves as a crushing part for further crushing the crushed object.

The base end of the crankshaft 38 is pivotally supported on the side surface of the pulley 42 by a shaft 44. 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 rotationally driven by winding an annular belt 80 around the pulley 72 and the pulley 42 attached to the output shaft of the gasoline engine 70. With the above configuration, when the pulley 42 rotates, the pressing blade base 30b swings, and the object to be crushed that has fallen from the primary crushing mechanism A is sandwiched between the pressing blades 32a and 32b, crushed, and drops downward. It will be. When the grain size of the crushed object by primary crushing is too large compared to the grain size at the time of reuse, by providing a secondary crushing mechanism in this way, the grain size suitable for reuse etc. It becomes possible to do.

Next, the structure of the crushed object sorting mechanism C will be described. 56 is a rectangular box-type sieve. The upper surface of the sieve 56 is open, one of the side surfaces is open, and the bottom surface is meshed. The mesh on the bottom is coarser near the open side and finer at the far side. The sieve 56 is provided below the crocodile-shaped pressing blade of the secondary crushing mechanism section and on the falling path of the crushed object. Sieve 5
The finer mesh on the bottom surface of 6 is located closer to the point where the crushed material from the secondary crushing mechanism falls. The two opposite sides of the bottom surface, which are in contact with the opposite side surfaces of the sieve 56 which are not opened, are supported by the rails 60 horizontally projecting from the opposite inner side surfaces of the housing 2 and can be moved in the horizontal direction. ing. The crankshaft 54 includes a shaft 58 provided on one side surface of a sieve 56 and a pulley 50 axially supported by the housing 2.
Is supported by a shaft 52 provided on a surface deviated from the center of the shaft, and forms a crank that swings the sieve 56.

With the above-described structure, when the pulley 50 rotates, the sieve 56 makes a simple vibration in the horizontal direction. As a result, the material to be crushed that has fallen from the secondary crushing mechanism section B moves on the sieve 56 from the finer side of the net to the coarser side of the screen, and is sorted by the grain size.

Next, the means for transmitting the driving force to the A, B, and C mechanism parts will be described. As described above, the transmission of power to the secondary crushing mechanism section B is performed by the engine 7 as a power source.
The pulley 72 is fixed to the output shaft of 0, and the annular belt 80 is stretched over the pulley 72 and the pulley 42.

To transmit power to the primary crushing mechanism A, a pulley 82 fixed to the base end of the shaft of the pulley 42 and a power input wheel 46 of the gearbox 4 are looped over an annular belt 84, and further the gear is Power output wheels 25 of box 4,
This is performed by hanging the annular belt 20 on the pulley fixed to the base end of the roll shaft 16a. Since the structure of the primary crushing mechanism A is as described above, the roll shaft 16
a, 16b, and the rotary vane 18 rotate.

Next, the transmission of power to the sorting mechanism C will be described. The annular belt 88 is stretched around the pulley fixed to the base end of the rotating roll shaft 16b and the pulley 86 whose both shaft ends are rotatably supported by the above structure. Further, the annular belt 90 is stretched over the pulley 86 and the pulley 50 described above. With the above configuration, the pulley 50 is rotated, and the sieve 56 is simply vibrated by the configuration of the sorting mechanism section C described above.

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

A glass wool makeup heat insulating plate (not shown) is attached to the outer periphery of the housing 2 as a soundproof material.
As a result, it is possible to reduce noise to the surroundings when the crusher is operating.

The roll shaft type crusher of this embodiment is characterized by the structure of the roll shafts 16a and 16b so that plate-like bodies such as roof tiles can be crushed reliably and efficiently. Figure 2
FIG. 7 is an explanatory view showing an enlarged configuration of 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 protrusion on the outer peripheral surface. The protrusions are arranged radially when viewed in the axial direction. The reason why the protrusions are arranged at intervals is to sandwich and crush the object to be crushed between the adjacent protrusions. In addition, in order to make it easier for the plate-like crushed object to be sandwiched between the projections, a plurality of sets of projections fixed side by side in the longitudinal direction of the roll shaft are provided in the circumferential direction of the roll shaft. To be

As a result, a plate-like crushed object such as a roof tile is
Since it is sandwiched between the rod-shaped projections and supported so as to stand in the radial direction of the roll shaft, 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 conventional roll-axis crushers,
By standing in the radial direction of the roll shaft, the crushing efficiency can be dramatically improved. In addition, by sandwiching the object to be crushed between the rod-shaped projections, the particles will be crushed in one collision to a grain size that is determined by the distance from the surface of the roll shaft to the reaction force rod, so crushing is efficient. To be the target. Also, if the size of the crushed object crushed by one collision with the reaction force 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 crushed object Grain size tends to be constant. In addition, since the shape of the projection attached to the roll shaft is rod-shaped, when hitting a reaction force rod, the crushed object escapes and is less likely to shake left and right.

As for the arrangement of the protrusions, there is a suitable arrangement depending on the shape of the crushed object. For example, when the object to be crushed has a rod-like shape, the protrusions are erected at finely spaced intervals so that the object to be crushed in a rod shape stands radially on the surface of the roll shaft. In this embodiment, as shown in FIGS. 2 and 3, in order to effectively crush a plate-shaped object to be crushed (roof), one set of rod-shaped projections is erected at regular intervals in the axial direction. A plurality of sets are assembled in the circumferential direction of the roll shaft. By doing so, the plate-like object to be crushed is sandwiched between the projecting body groups adjacent to each other in the circumferential direction while standing in the radial direction of the roll shaft.

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 the set of circumferential projections is There were 12 sets at equal intervals. The arrangement and number of protrusions can be set as appropriate.

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

The rotary blade 18 shown in FIG. 2 has a plate-shaped blade 1 on the outer peripheral surface.
8a is provided upright. In the plate-like wing 18a, the longitudinal direction of the rotation axis of the rotary wing 18 and the longitudinal direction of the plate-like wing 18a are substantially parallel to each other, and each of them makes an angle of 90 degrees when viewed from the longitudinal direction of the rotary axis, and the wing 4a has four radial directions. One piece is erected. As the rotary blades 18 rotate, they lie horizontally near the hopper above the roll shaft 16 and the protrusion 2 on the roll shaft 16
It becomes possible to stir the crushed object that is idling without being vertically sandwiched between 6 and sandwich it between the protrusions 26. By this mechanism, the roof tile can be smoothly introduced into the primary crushing mechanism without bothering the operator.

Another structural example of the roll shaft is shown in FIG. In this example, the protrusions 26 on the roll shaft 16 are spirally arranged in the axial direction of the rotary shaft 16. As a result, it is possible to gradually break the crushed object without contacting it with the reaction force rod at once.

Next, the operation of this embodiment will be described. In FIG. 1, when an object to be crushed, for example, a roof tile is put into the hopper while the engine 70 is operating, the roof tile is guided to the inclined surface of the hopper side surface or directly, the roll shaft 16a of the rear part A of the primary crusher, Reach the top of 16b. Since the rod-shaped projections 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 projections in the radial direction of the roll shaft 16. Stand up and fit. Some thrown roof tiles do not fit between the protrusions and idle around the middle of the roll shafts 16a and 16b while lying horizontally. Such roof tiles are agitated by the plate-like blades of the rotary blades 18 and one end of the roof tiles is lifted, so that the roof tiles are fitted between the protrusions.

The roof tile sandwiched between the projections on the roll shafts 16a and 16b rotates together with the roll shafts 16a and 16b,
The portion protruding from the protrusion to the outside collides with the reaction force rod 14. The roof tile is sandwiched between the protrusion and the reaction force rod 14 and crushed by the rotating force of the rotating shafts 16a and 16b. At this time, the roof tile has a substantially constant size determined by the distance from the surfaces of the rotating shafts 16a and 16b to the reaction force rod 14,
Since it is crushed by one collision, the efficiency of crushing is better than that of a conventional roll-shaft crusher in which the grain size crushed by one collision becomes indefinite.

The roof tiles crushed by the roll shafts 16a and 16b and the reaction force rod 14 fall to the upper part of the secondary crushing mechanism B. As described above, since the opposing side surfaces of the secondary crushing mechanism B are inclined toward the inside of the casing due to the shapes of the pressing blade bases 30a and 30b, the crushed object has a lower pressing blade 32a. , 32b. By converting the rotation of the pulley 42 into a reciprocating motion with the crankshaft 38 and swinging the pressing blade base 30b, the pressing blades 32a and 32b are
Open and close exercise. The roof tiles on the a part are pressing blades 32a, 3
When the space between 2b is opened, it falls in the middle, and when it is closed, it is crushed and further crushed.

The roof tile crushed at the position B of the secondary crushing mechanism B falls on the sieve 56 of the sorting mechanism C. As described above, the falling point of the crushed object of the secondary crushing mechanism is the sieve 56.
Since the sieve is a fine part, when the sieve 56 vibrates, the fine particles in the crushed material first drop below the sieve 56. The sieve 56 of the sorting mechanism C is
Since it oscillates in a single horizontal direction, the crushed material is sieved.
Move up horizontally. Since the mesh of the bottom of the sieve 56 becomes coarser as it goes away from the secondary crushing mechanism, the crushed object is gradually sieved from the one with the smallest grain size.
6 will fall through the mesh, 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 object to be crushed can be sorted according to the grain size.

FIG. 5 shows another embodiment of the roll shaft crusher. In this embodiment, the roll shaft 1 of the primary crushing mechanism E is
Only one 6c is arranged. 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 provided so that finer crushing can be performed.
The distance of 6d is made shorter than that of the primary crushing mechanism E. In addition, the distance between the rod-shaped blades 26b as rod-shaped projections 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 arranging a plurality of sets of protrusions standing side by side in the longitudinal direction of the roll shaft in the circumferential direction of the roll shaft. You may make it provide multiple sets. Further, the outer peripheral edge portion of the plate 28 is casing so that the inner surface of the semi-cylindrical plate 28 in which a large number of holes having a diameter of about several mm are formed below the secondary crushing mechanism F is along the outer periphery of the roll shaft 16d. Body 2
By fixing it to the inner circumference, the crushed material can be crushed to almost a specific grain size. Since the primary crushing mechanism E has only one roll shaft 16 as compared with the primary crushing mechanism A of FIG. 1, it can be designed more compactly. The secondary crushing mechanism is for crushing the object to be crushed by the primary crushing mechanism into finer pieces, like the secondary crushing mechanism B in FIG.

As described above, the secondary crushing mechanism for finely crushing the object to be crushed by the primary crushing mechanism is the one using the pressing blade like the secondary crushing mechanism B of FIG. 1, and the secondary crushing mechanism of FIG. Based on the same principle as the primary crushing mechanism, such as the crushing mechanism F,
Alternatively, it is possible to select from a variety of variations depending on the type of crushed material and the grain size suitable for reuse, such as by a stone mill type mechanism. Alternatively, the secondary crushing mechanism may not be necessarily provided as long as a sufficiently fine grain size can be obtained by the crushing by the primary crushing mechanism.

FIG. 6 shows an example in which a slope is provided as another structural example of the above-mentioned sorting mechanism. FIG. 6 is a side sectional view of a crusher in which the sorting mechanism C shown in FIG. 1 is changed to a system on a slope as seen from the side. Reference numeral 108 denotes a net slope composed of a square net and plates attached along two opposite sides of the net for preventing the crushed object from falling off the side of the net. The mesh slope 108 has the plate surface attached obliquely to the horizontal direction on the opposite side surfaces of the housing 2 with the mesh surface facing downward. Further, the net slope 108 is attached such that the upper end of the diagonally sloped part is positioned on the falling path of the crushed object from the secondary crushing mechanism.

Reference numeral 110 denotes an iron plate slope composed of a rectangular iron plate and plates attached along the two opposite 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 is attached to the opposite side surfaces of the housing 2 with the plate of the net slope 108 at an angle inclined in the 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-described structure, the crushed material that has fallen from the secondary crushing mechanism B drops onto the upper portion of the net slope 108, and those that have passed through the mesh of the net slope 108 onto the iron plate slope 110, and the net. Anything that does not pass through the eye will fall from the bottom edge of the slope. On the other hand, the crushed material that has fallen onto the iron plate slope 110 is
It will slide over 0 and fall from the lower end of the slope.
In this way, the crushed objects can be sorted according to the grain size. According to this mechanism, the material to be crushed can be speedily separated into two stages of grain size. Also, the magnet 102,
By 106, the metals mixed in the crushed object can be attracted and the metals can be removed, and the crushed object after crushing can be easily reused or discarded.

When the tile is actually crushed using the tile crusher of this embodiment, the tile has a diameter of about 30 due to 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 with a diameter of about 2 mm to 3 mm. For the purpose of disposal such as landfill, the grain size of primary crushing is sufficient, but by crushing secondary,
It could be efficiently crushed to a grain size (about 2 mm to 3 mm in diameter) that can be reused as a raw material for nanban stucco, mortar, antoker, and spread sand.

Since the roof tile has a property of absorbing moisture as compared with sand and gravel, it can be suitably used as a raw material (aggregate) for mortar and nanban stucco if it is crushed to an appropriate grain size. . According to the crusher according to the present invention, as described above,
A single crusher can crush the roof tiles to the point where it can be reused, and sufficient processing capacity can be obtained even if the size is reduced. Therefore, as shown in Fig. 7, the crusher is mounted on the truck bed for transportation. It is also possible to do so. 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 transported by a 2t truck. Furthermore, if the components of the tile crusher are optimally downsized, it is possible to carry them by light truck.

By using the crusher which is easy to transport in this way, the tile builder can transport the tile crusher to the construction site and simultaneously remove the old tile from the roof to crush the tile. Moreover, since the crushed roof tiles can be used as the raw material (aggregate) of the Nanban plaster for the roof on the spot, the amount of roof tile waste that must be transported and discarded can be reduced, and the transportation and disposal costs and labor can be reduced. This has the effect of reducing the cost of purchasing materials.

[0046]

According to the present invention, the object to be crushed can be efficiently and finely crushed, and particularly, the plate-shaped object to be crushed can be effectively crushed. In addition, the crusher 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- or small-sized trucks, the tiles can be crushed at one time at the construction site, and mortar made from old tiles can be used as a raw material.
With the ability to produce nanban plaster for roofs, sand laid, and raw materials for Antucar, it has a great effect on cost, labor, and waste reduction.
