Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing apparatus for finely crushing crushed materials such as wood chips.

[0002]

2. Description of the Related Art Conventionally, there has been known a chip making machine capable of efficiently crushing relatively large wood chips such as trims and long materials (see Japanese Patent Publication No. 61-16603). As shown in FIG. 7, this chip manufacturing machine is provided with a rotating drum 82 rotatable around a horizontal axis near the bottom of a device body 80 having a hollow inside, and a crushing blade 83 However, the receiving blade 84 is provided on the outer periphery of the rotation locus.

The chip making machine shown in the figure is of a double type having two rotating drums 82. Trimmed material and the like can be supplied from the upper portion of the apparatus main body 80, and long material and the like can be supplied from a material insertion port 85 provided on a side wall of the apparatus main body 80. FIG.
Is a single type having only one rotating drum 82. In this type of chip manufacturing machine, a sorting body 87 is provided below the crushing blade 83. As shown in FIG. 9, this sorting body 87 has a rectangular disk shape curved along the rotation peripheral region of the crushing blade 83, and has a grid body 8 in a frame 88.
9 is provided, and the passing roughness of the crushed material is regulated by the size of each lattice. That is, the crushed material that does not reach the predetermined roughness (coarse) is repeatedly discharged and crushed by the crushing blade 83 until the crushed material reaches a size that can pass through the grid without being discharged from the apparatus main body 80.

[0004] Such a sorting body 87 is attached to the lower part of the rotating peripheral area of the crushing blade 83 from below the apparatus main body 80, and is fixed to the apparatus main body 80 by a bolt 90 inserted from below. By the way, if the wood dust is reduced to sawdust and finer powder, the obtained dust can be reused in livestock industry, agriculture, etc.
Therefore, there is an advantage that not only the waste treatment is unnecessary but also the dust can be sold as a product. Therefore, in the above-mentioned chip making machine, it has been considered to attach a sieve material (not shown) made of a net material or the like having an opening of about several millimeters on the upper surface of the sorting body 87. In this case, it has been found that planer dust, chip material, and the like generated in a canner or the like are suitable as the crushing material.

[0005]

In the conventional chip making machine, as described above, the sorting body 87 is mounted from below the apparatus main body 80 to the lower part of the rotation peripheral region of the crushing blade 83. For this reason, once the apparatus main body 80 is installed in the factory, the crushed debris take-out apparatus such as a duct or a conveyor installed below the apparatus becomes an obstacle, and it is not easy to attach and detach the sorting body 87. Was something.

However, the sieve material attached to the sorting body 87 is inevitably weak in strength as compared with the rigid structure of the lattice body 89, and may rarely break. For example, when elongation or rust occurs due to long-term use of the sieve material, when metal pieces such as nails are mixed in the crushed material, or when the crushing blade 83 or the receiving blade 84 is broken by the crushing blade 83 When the gap between the filter and the sorting body 87 is clogged, the sieve material may be broken. In addition, even when the crushed material contains moisture and clogs the sieve material, there is a high possibility that the sieve material will be broken. Had to be applied.

In such a case, the sorting body 87 can be taken out without removing all the debris removal device from the lower part of the apparatus main body 80, or without extensive preparation such as lifting the apparatus main body 80 itself with a crane or the like. I ca n’t
Changing the sieve material was extremely difficult. In addition, as is apparent from such circumstances, the sifting material is frequently replaced with a material having a different opening, and the roughness of the dust to be obtained may be changed as desired. Was virtually impossible.

[0008] The present invention has been made in view of the above circumstances, and is intended to make it possible to quickly and easily replace or maintain a sieve material provided on a sorting body and to reduce the size of a crushed material to a powder state. It is an object of the present invention to provide a crushing processing apparatus which is substantially enabled and which can easily change the roughness of the dust to be obtained as desired.

[0009]

According to the present invention, the following technical measures have been taken in order to achieve the above object. That is, in the present invention, the sorting body is detachable by sliding in the lateral direction with respect to the apparatus main body. Therefore, when replacing or maintaining the sieve material to be attached to the sorting body, there is no need to remove all the crushed debris removal device from below the device main body or to lift the device main body itself with a crane or the like at all.

[0010] If the selection body is provided so that the installation state in the apparatus main body can be fixed by a bolt fixed from the outside of the side wall of the apparatus main body, an operation of tightening or loosening the bolt can be performed outside the apparatus main body. Since it can be done, the attachment and detachment of the sorting body becomes even easier. In addition, the sorting body may be fixed to the frame by welding a sieve material to the frame, or may be detachably attached using bolts or the like. As this sieve material, a net material can be used,
A perforated plate such as a punching metal can also be used.

However, the mesh material has a higher aperture ratio than a perforated plate, and a large number of fine undulations are formed on the surface as a result of having a wire woven structure. There is an advantage that the powder material passing rate can be increased. Further, the sorting body may be the same as the conventional one having the lattice body inside the frame. Note that a structure in which a sieve material is attached on the lattice body may be used.

On the side wall of the main body of the apparatus, there is provided a passage for the sorting body for a portion where the sorting body is attached and detached by sliding. Therefore, it is preferable to provide a spacer on the sorting body so as to fit into the passage opening when installed on the apparatus main body. This spacer has a thickness equal to the thickness of the side wall around the passage opening in the apparatus main body.
By doing so, the passage opening can be closed by the spacer when the sorting body is inserted into the apparatus main body, and the crushed material can be prevented from staying at this portion.

That is, the spacer acts as an inner wall corresponding to the passage opening of the apparatus main body.
On the other hand, when a spacer is provided on the sorting body in this way, it is preferable that the sorting body is further provided with a sealing lid that can be brought into contact with the peripheral portion of the passage opening of the apparatus body outside the spacer. This sealing lid closes a gap formed between the inner edge of the opening of the passage opening and the outer edge of the spacer fitted therein, thereby preventing air from flowing.

That is, by providing the sealing lid, it is possible to prevent the air flow generated by the rotating crushing blade from being blown out of the apparatus main body.
Leakage and reduction of crushing efficiency can be prevented.
The spacer and the sealing lid can be formed integrally with each other, or these spacers and the sealing lid can be provided integrally with the sorting body.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. 5 and 6 are overall views of the crushing apparatus 1 according to the present invention, wherein FIG. 5 is a front view and FIG. 6 is a plan view. In the crushing apparatus 1, a device main body 3 is installed on a base frame 2, a material supply duct 4 is provided at an upper portion of the device main body 3, and a material removal hopper 5 is provided at a lower portion of the device main body 3. Each is attached. Therefore, the crushed material is introduced into the apparatus main body 3 through the duct 4 and the hopper 5 by the cyclone method,
The dust obtained after the crushing is removed from the apparatus main body 3.

In this crushing apparatus 1, the structure for finely crushing the crushed material is basically the same as that of the conventional one (see FIG. 7). The crushed material is crushed in cooperation with the receiving blade 84, and only the crushed material which has reached a predetermined roughness is separated by a sorting body 87 (indicated by reference numeral 6 in the present invention) provided at a lower portion of the rotation peripheral region of the crushing blade 83. Those that are discharged from the main body 3 and do not reach the predetermined roughness (coarse) are repeatedly subjected to a crushing action in the apparatus main body 3.

Since this embodiment is of a double type having two rotating drums 82, parts extending on both sides of the base frame 2 around the installation position of the apparatus main body 3 are provided on the base frame 2. A motor 8 that transmits the rotational drive via the winding transmission means 7 to the rotating drum 82 is provided. In the crushing apparatus 1 according to the present invention, two wrapping transmission means 7 are provided on one side surface of the apparatus main body 3 so as to be adjacent to each other.
Are arranged in the same direction. By doing so, the other side surface of the apparatus main body 3 can be in a state where the wrapping transmission means 7 is not provided.

As described above, the bearing 13 for supporting the rotating shaft 12 of the rotating body 82 is provided on the side of the apparatus main body 3 where the wrapping transmission means 7 is not provided, as shown in FIGS. The bearing 13 is not a pillow type but a flange type. For this reason, as much open space as possible can be ensured at the lower part of the bearing 13.

A passage 16 for the sorting body 6 is formed in the lower open space of the bearing 13 so that the sorting body 6 can be detached by sliding the sorting body 6 in the lateral direction. The reason why such a contrivance is required in the bearing 13 is that the rotational diameter of the crushing blade 83 and the size of the bearing 13 required to stably support the crushing blade 83 are substantially the same. This is because when the pillow type 13 is used, a space for sliding the sorting body 6 interferes with the pillow type.

With the use of the flange 13 as the bearing 13, the bearing 13 can be cut out of steel instead of the cast iron product which is predominant in the pillow type. . Therefore, the bearing 13 can be made strong in strength, and the life can be extended. As shown in FIG. 3, the sorting body 6 used in the present invention includes a frame 17 and a sieve material 1 provided on an upper portion of the frame 17.
8 is provided. The sieve material 18 is detachable from the frame 17.

The sieve material 18 has a curved plate shape with a concave upper surface so as to form a partial cylindrical surface along the rotation peripheral region of the crushing blade 83. As the material, a stainless steel punching metal, a stainless steel net material, or the like is used. The sieve material 18 is formed with a large number of holes having a diameter of about 3 mm to 5 mm. In the sieve material 18, connection pieces 20 bent toward the frame 17 are provided at both ends of the concavely curved side. Further, screw through holes 21 are formed at predetermined intervals at both end edges that intersect the concave curve.

On the other hand, the frame 17 is formed by assembling a strip made of a flat bar or the like into a box by welding or the like.
A plurality of reinforcing ribs 23 made of a band plate are also provided inside the box frame.
Is provided. The upper edges of these reinforcing ribs 23 are curved along the concave curvature of the sieve material 18. The frame 17 is provided with a positioning recess 24 into which the connection piece 20 of the sieve material 18 can be fitted. In addition, a female screw hole 25 that can match the screw hole 21 on one side of the sieve material 18 and a screw hole 26 that can match the screw hole 21 on the other side are provided. Further, on the outer peripheral surface of the frame 17, a female screw hole 27 for fixing the inserted state is provided on a side surface closer to the side wall of the apparatus main body 3, and a spacer mounting female screw hole is provided on a side surface facing the front side. 28 are provided.

When the sieve material 18 is fixed to the frame 17, a wavy bend occurs between the screw holes 21 in the sieve material 18 when bolts are fastened, or a crack originating from the screw hole 21 occurs. To prevent
9, 30 are used. One backing plate 29
Is fixed by a bolt (not shown) screwed into the female screw hole 25 of the frame 17, and a screw member 31 is fixed to the back surface of the other backing plate 30. The frame 17 is fixed by screwing a nut (not shown) from the back side of the frame 17 through the screw through hole 21 of 18 and the screw through hole 26 of the frame 17.

The sorting body 6 thus formed has a spacer 34 on the side face facing the front side when inserted into the passage 16 of the apparatus main body 3 as shown in FIGS.
And a sealing lid 35. The spacer 34 has a position and a size that fits into the passage 16 when the sorting body 6 is inserted into the passage 16 of the apparatus main body 3,
It has a thickness equal to the side wall thickness around the passage opening 16.
It is attached to the sorting body 6 by a bolt 36 which is screwed into the female screw hole 28 for attaching a spacer. The spacer 34 has a female screw hole 37 for attaching a sealing lid.
Is provided.

The sealing lid 35 is formed to be slightly larger than the size of the sorting body 6 on the front side, and when the sorting body 6 is inserted into the apparatus main body 3 and installed, the sealing lid 35 opens the passage opening 16. It comes into contact with the periphery. For the sorting body 6, the female screw hole 3 for attaching the closed lid of the spacer 34 is provided.
7 is indirectly attached by bolts 38 that screw into it.

A large hole 40 is formed in the closed lid 35 in order to avoid interference with the bolt 36 that attaches the spacer 34 to the sorting body 6. I have. At the four corners of the sealing lid 35, a plurality of screw holes 41 are provided so as to correspond to around the passage opening 16 of the apparatus main body 3. Further, a handle 42 and an eyebolt 43 are attached to the closed lid 35 so that handling when the sorting body 6 is attached to and detached from the apparatus main body 3 is convenient.

For this reason, when the sorting body 6 is inserted and installed in the apparatus main body 3, the inner surface of the spacer 34 is flush with the inner surface of the side wall of the apparatus main body 3, and the passage port 16 serves as an inner wall.
Thus, the crushed material does not stay on both sides of the sieve material 18. In addition, the sealing lid 35 is positioned between the inner edge of the opening of the passage opening 16 and the spacer 34.
To block the flow of air, thereby preventing the air flow generated by the rotating crushing blade 83 from blowing out of the apparatus main body 3 and clogging, leaking, and crushing the crushed material. A decrease in efficiency or the like is prevented.

In addition, when the sorting body 6 is loaded, the apparatus main body 3 has a screw through hole 45 that can match with the female screw hole 27 provided on the side surface of the sorting body 6, and a screw hole provided in the sealing lid 35. A female screw hole 46 is provided which can fit in the through hole 41, and the sorting body 6 can be fixed to the apparatus main body 3 by bolts 47 and 48 inserted and screwed into these.

As shown in FIG. 2, the apparatus main body 3 has a lower rail 50 for supporting both lower sides of the sorting body 6 and a proper upper part of the sorting body 6 for facilitating taking-in and out of the sorting body 6. Is provided on the upper rail 51 so that the upper rail 51 can be prevented from floating. Since the crushing apparatus 1 according to the present invention has the above-described configuration, the sorting body 6 can be taken out by simply loosening and removing the bolts 47 and 48 outside the apparatus main body 3. Therefore, it is possible to easily perform maintenance such as removing a clog in the taken-out sorting body 6 and to replace the sorting body 6. In addition, since the sorting body 6 has a structure in which the sieve 18 can be easily attached to and detached from the frame 17, when the sieve 18 is torn, stretched or rusted, only the sieve 18 is replaced. You can do it easily.

Needless to say, it is possible to easily make the sieve material 18 having a different mesh size, a different number of meshes, a different structure (such as a difference between a perforated plate and a net material) or the like. Become. Note that the present invention is also applicable to a case where the screening member 6 is not provided with the sieve material 18, that is, a case where a conventional screening body 87 (see FIG. 9) is used as it is.

The present invention can be applied not only to the double type but also to the single type. In the sorting body 6, the sieve material 18 can be fixed to the frame 17 by welding or the like. The selection body 6 is not limited to be provided below the rotation peripheral area of the crushing blade 83, and when the outlet by the cyclone method is provided on the side wall of the apparatus main body 3, for example. It is also possible to provide the sorting body 6 on the side.

[0032]

As is clear from the above description, since the sorting body can be detached by sliding it in the lateral direction with respect to the apparatus main body, the sieve material to be attached to the sorting body is exchanged or maintained. Can be done very quickly and easily. In this case, if the selecting body is configured to be fixed by a bolt fixed from the outside of the side wall of the apparatus main body, the work of attaching and detaching the selecting body can be further facilitated.

If a spacer is provided on the sorting body, the spacer blocks the passage for the sorting body provided on the side wall of the apparatus main body, and the inner wall of the apparatus body becomes flush. Material can be prevented from staying. Further, if a sealing lid is further provided for the sorting body, the sealing lid closes a gap formed between the opening edge of the passage opening and the outer peripheral edge of the spacer so as to prevent the flow of air. Therefore, clogging or leakage of the crushed material during rotation of the crushing blade, reduction in crushing efficiency, and the like can be prevented.
