Description

[Technical field]

[0001] The present invention relates to a crushing device for crushing objects to be treated and a method for manufacturing the crushing device. [Background technology]

[0002] 2. Description of the Related Art Generally, as one of means for treating objects to be treated, such as waste discharged from homes, factories, etc., a crushing device for crushing the objects to be treated into pieces of a certain size is known.

[0003] Known examples of such crushing devices include those that crush objects by rotating a cutter unit attached to a rotating shaft, and in such crushing devices, a spacer unit is provided to define the distance between the cutter units when the cutter units are attached to the rotating shaft. For example, Patent Document 1 describes a crushing device in which cutter sections and spacer sections are alternately arranged with respect to a rotation axis, and the cutter sections and spacer sections are separable. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 10-244179 Summary of the Invention [Problem to be solved by the invention]

[0005] In the case of a crushing device such as that disclosed in Patent Document 1, the cutter section and the spacer section can be easily removed, but the interval between the cutter sections formed by the spacer section is constant. On the other hand, when the object to be treated is crushed by a crushing device, if the object to be treated is large, the object to be treated may remain on the cutter section, and the crushing process may not be efficient. In such a case, the efficiency of the crushing process of the object to be treated can be improved by increasing the diameter or thickness of the cutter section. Here, when the diameter of the cutter part is increased, it is necessary to update the entire crushing device to match the diameter of the cutter part, such as by adjusting the position of the rotation axis of the cutter part. Therefore, it is preferable to maintain the diameter of the cutter part and increase the thickness of the cutter part in order to improve the crushing efficiency. However, if a new cutter part and spacer part with a large thickness are to be created in order to improve the crushing efficiency, there is a problem in that it takes time and costs to create them.

[0006] In addition, depending on the object to be processed, it may be necessary to classify the crushed material by material after crushing the object to be processed. In such a case, if the crushed material is too small or too large, it takes time to classify it, so it may be necessary to control the size of the crushed material. Since the size of the crushed material varies depending on the thickness of the cutter part and the thickness of the spacer part, it is necessary to remake the cutter part and the spacer part according to the size of the crushed material, which causes a problem of time and cost required for the creation.

[0007] Therefore, an object of the present invention is to provide a crushing device and a manufacturing method for the crushing device, which are capable of easily changing the thickness of the cutter portion or the thickness of the spacer portion. [Means for solving the problem]

[0008] As a result of intensive research into the above-mentioned problems, the inventors discovered that the thickness of the cutter portion or the thickness of the spacer can be easily changed by arranging two or more cutter members or two or more spacer members adjacent to each other, and thus completed the present invention.

[0009] In order to solve the above problems, the crushing device of the present invention is characterized in that, in a crushing device in which crushing blades consisting of a cutter section and a spacer section are stacked, the cutter section or the spacer section is composed of two or more cutter members or two or more spacer members arranged adjacent to each other. According to this feature, by constructing the cutter section or spacer section so that two or more cutter elements or two or more spacer elements are adjacent to each other, the thickness of the cutter section or the spacer section can be easily changed by changing the number of adjacent cutter elements or spacer members.

[0010] Furthermore, one embodiment of the crushing device of the present invention is characterized in that a member in which a cutter member and a spacer member are integrally provided is used. According to this feature, since the cutter member and the spacer member are integrally provided, it is possible to reduce the number of parts required to form the crushing blade. Also, since it is no longer necessary to stack the cutter member and the spacer member separately, it is possible to improve the workability in assembly.

[0011] According to the manufacturing method of the crushing device of the present invention for solving the above problems, in the manufacturing method of the crushing device in which crushing blades consisting of a cutter section and a spacer section are stacked, the cutter section or the spacer section is characterized by including a step of arranging two or more cutter members or two or more spacer members adjacent to each other. According to this feature, by including a step of arranging two or more cutter members or two or more spacer members adjacent to each other, it is possible to manufacture a crushing device in which the thickness of the cutter section or the thickness of the spacer section can be easily changed by changing the number of adjacent cutter members or spacer members. Effect of the Invention

[0012] According to the present invention, it is possible to provide a crushing device in which the thickness of the cutter section or the spacer section can be easily changed, and a method for manufacturing the crushing device. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the crushing device according to the present invention will be described with reference to the drawings. Also, the manufacturing method of the crushing device according to the present invention is replaced with the following description of the structure of the crushing device. The embodiment shows an example of a crushing device. The crushing device according to the present invention is not limited to the embodiment, and the crushing device according to the embodiment may be modified within the scope of the gist described in the claims.

[0015] There is no particular limitation on the object to be crushed by the crushing device of the present invention. For example, general waste and industrial waste discharged from homes and factories, or sewage residue, etc. can be mentioned. In particular, the crushing device can be suitably used for objects to be crushed, such as household products and industrial products that are made of a mixture of multiple materials, which require the size of the crushed objects to be controlled in order to classify the crushed objects by material after crushing.

[0016] [First embodiment] Fig. 1 is a schematic explanatory diagram showing the structure of a crushing device 1A according to a first embodiment of the present invention. Fig. 1(A) is a side view of the crushing device 1A, and Fig. 1(B) is a plan view of the crushing device 1A seen from above. Note that Fig. 1(B) omits illustration of a driving motor and a casing.

[0017] [Crushing equipment] As shown in FIG. 1(A), the crushing device 1A of the first embodiment of the present invention comprises a drive motor 2, a drive shaft 5a driven by the drive motor 2, a driven shaft 5b driven by the rotational power of the drive shaft 5a, and a plurality of crushing blades 6 arranged around the drive shaft 5a and the driven shaft 5b. The crushing device 1A also includes a casing 3 that houses cutter units 4a and 4b formed by combining the crushing blade 6 and a drive shaft 5a, and the crushing blade 6 and a driven shaft 5b. Furthermore, the crushing blade 6 includes a cutter section 61a having a plurality of cutter members 610a, and a spacer section 62a having a plurality of spacer members 620a. Each component of the crushing device 1A of this embodiment will be described below.

[0018] [Drive motor] The drive motor 2 is for transmitting rotational power to the drive shaft 5a to rotate the crushing blade 6. Any type of rotating mechanism may be used for the drive motor 2. For example, an electric motor, a hydraulic motor, a water pressure motor, an air pressure motor, etc. may be used.

[0019] [Drive shaft] The drive shaft 5a is a shaft member that rotates by the rotational power of the drive motor 2. In addition, the crushing blade 6 is disposed around the drive shaft 5a, and the crushing blade 6 rotates at a predetermined speed together with the rotation of the drive shaft 5a. The shape of the drive shaft 5a may be any shape that can fix the crushing blade 6 arranged around it. For example, the drive shaft 5a may have a convex portion and the crushing blade 6 may have a concave portion, which engage with each other; or the drive shaft 5a may have a polygonal cross-section, and the crushing blade 6 may have a polygonal shaped shaft hole in the center thereof, which has approximately the same polygonal shape as the drive shaft 5a, for engagement therewith.

[0020] [Driven axis] The driven shaft 5b is a shaft member that rotates when the rotational power of the drive motor 2 is transmitted via the drive shaft 5a. Similarly to the drive shaft 5a, the crushing blade 6 is disposed around the driven shaft 5b, and the crushing blade 6 rotates at a predetermined speed with the rotation of the driven shaft 5b. The shape of the fixing of the driven shaft 5b and the crushing blade 6 is not particularly limited. For example, the same shape as that of the fixing of the drive shaft 5a and the crushing blade 6 may be used.

[0021] The means for transmitting the rotational power from the drive shaft 5a to the driven shaft 5b is not particularly limited, but may be, for example, a means for connecting the pulleys installed at the upper ends of the shafts with a belt or a means for connecting with gears. In this embodiment, the rotating shaft for rotating the crushing blade 6 is shown as being composed of the drive shaft 5a and the driven shaft 5b, but is not limited thereto. For example, it may be possible to use a shaft in which each shaft is driven independently. Furthermore, the relationship between the rotation speeds of the drive shaft 5a and the driven shaft 5b is not particularly limited. For example, the drive shaft 5a and the driven shaft 5b may be rotated at different speeds, or the drive shaft 5a and the driven shaft 5b may be rotated at the same speed. The relationship between the rotation speeds of the rotating shafts can be appropriately set in consideration of the ease of structural design related to the means for transmitting the rotational power, the amount of power consumption related to driving, and the like.

[0022] [Crushing blade] The crushing blade 6 is configured by concentrically overlapping a disk-shaped cutter portion 61a and a spacer portion 62a having a smaller diameter than the cutter portion 61a. In addition, a shaft hole is formed in the center of the crushing blade 6 to pass the rotating shaft (the driving shaft 5a and the driven shaft 5b).

[0023] 1(B), the crushing blades 6 are arranged around the driving shaft 5a and the driven shaft 5b so that a plurality of crushing blades 6 are stacked to form cutter units 4a and 4b. The cutter units 4a and 4b are installed inside the casing 3 such that the cutter portion 61a of one cutter unit engages with the gap formed by the spacer portion 62a of the other cutter unit. As shown in Figure 1(A), the casing 3 housing the cutter units 4a and 4b has an inlet 31 at the top (upper side of the figure) through which the material to be treated is fed, and a discharge outlet 32 ​​at the bottom (lower side of the figure) through which the material to be treated (crushed material) is discharged.

[0024] 1(B), the cutter unit 4a rotates counterclockwise when viewed from above the crusher 1A, and the cutter unit 4b rotates clockwise. When the object to be processed is fed from the top (feed inlet 31) of the crusher 1A, the object passes between the cutter units 4a and 4b and is cut by the cutter portion 61a of the crushing blade 6.

[0025] The cutter portion 61a and the spacer portion 62a which form the cutter units 4a and 4b will be described in detail below.

[0026] [Cutter section] The cutter portion 61a has a plurality of cutting blades evenly arranged on the outer periphery, and serves to guide the object to be processed between the cutter units 4a and 4b. The cutting edge pieces are structures protruding from the outer periphery of the cutter portion 61a, and examples include structures having multiple structures with convex portions in the circumferential direction, as well as structures having multiple structures with acute angle portions in the circumferential direction.

[0027] The size of the cutter portion 61a (the diameter of the circle passing through the outermost part of the plurality of cutting blade pieces) is not particularly limited, but is preferably, for example, 10 cm or more and 50 cm or less. If it is within this range, it becomes possible to efficiently crush the object to be processed.

[0028] The cutter section 61a in this embodiment is formed by combining a plurality of cutter members 610a, which makes it possible to easily adjust the thickness of the cutter section 61a by changing the number of cutter members 610a to be stacked.

[0029] The cutter member 610a functions as a unit in the cutter section 61a. The thickness of the cutter member 610a is preferably thin and has the strength to crush the object to be processed, which allows a wider range of options for the thickness of the cutter section 61a that can be adjusted by changing the number of adjacent cutter members 610a.

[0030] The thickness of the cutter member 610a is not particularly limited, but is preferably, for example, 5 mm or more and 30 mm or less. This range is preferable because it has sufficient strength to crush the object to be processed and the thickness of the cutter part 61a as a unit can be easily adjusted to an appropriate size. For example, when obtaining a thickness of the cutter part 61a suitable for controlling the size of the crushed object, such as classifying the crushed object of the object to be processed, this thickness is preferably used as the thickness of the cutter member 610a that functions as a unit.

[0031] [Spacer part] The spacer portion 62a is for ensuring a gap between the cutter portions 61a of the cutter units 4a and 4b in the direction of the rotation axis (the drive shaft 5a or the driven shaft 5b).

[0032] The spacer portion 62a in this embodiment is formed by combining a plurality of spacer members 620a, which makes it possible to easily adjust the thickness of the spacer portion 62a by changing the number of spacer members 620a to be stacked.

[0033] The spacer member 620a functions as a unit in the spacer portion 62a. The thickness of the spacer member 620a is preferably thin and has the strength to maintain the distance between the cutter parts 61a arranged in the driving shaft 5a direction or the driven shaft 5b direction, which makes it possible to expand the options for the thickness of the spacer part 62a that can be adjusted by changing the number of adjacent spacer members 620a.

[0034] The thickness of the spacer member 620a is not particularly limited, but is preferably 5 mm or more and 30 mm or less, the same as the cutter member 610a. This range is preferable because it has sufficient strength to maintain the interval between the cutter parts 61a and is easy to adjust the thickness of the spacer part 62a to an appropriate size as a unit. For example, when obtaining a thickness of the spacer part 62a suitable for controlling the size of the crushed material, such as classifying the crushed material of the processing object, this thickness is preferably used as the thickness of the spacer member 620a that functions as a unit.

[0035] It is preferable that the thickness of the spacer member 620a is thicker than the thickness of the cutter member 610a. This ensures a gap so that the cutter portions 61a of the cutter unit 4a and the cutter unit 4b do not rub against each other when the cutter portion 61a of the cutter unit 4b (or the cutter unit 4a) engages with the gap ensured by the spacer portion 62a of the cutter unit 4a (or the cutter unit 4b).

[0036] [Arrangement of cutter and spacer parts] An example of a combination of the cutter portion 61a and the spacer portion 62a will be described with reference to Fig. 2. The white arrows in Fig. 2 indicate a process of arranging each member adjacent to the drive shaft 5a as an example of the arrangement of the cutter portion 61a and the spacer portion 62a. 2, two cutter members 610a having the same thickness are arranged adjacent to each other to form a cutter section 61a, and two spacer members 620a having the same thickness are arranged adjacent to each other to form a spacer section 62a, thereby forming a crushing blade 6 having a cutter section 61a and a spacer section 62a. A plurality of the crushing blades 6 are stacked on the driving shaft 5a or the driven shaft 5b to form the cutter units 4a and 4b.

[0037] In this embodiment, the number (n) of adjacent cutter members 610a and the number (m) of adjacent spacer members 620a are each set to 2, but the adjacent numbers (n and m) may be set to 3 or more. This makes it possible to change the distance between the cutter portions 61a in the cutter units 4a and 4b simply by changing the adjacent numbers (n and m).

[0038] As described above, in the crushing device 1A of this embodiment, two or more cutter members or two or more spacer members are arranged adjacent to each other, and by changing the number of adjacent cutter members or spacer members, the thickness of the cutter section or the thickness of the spacer section can be easily changed. This means that when aiming to improve the crushing efficiency in accordance with the size of the object to be processed or when wanting to control the size of the crushed pieces of the object to be processed, there is no need to design or create new cutter or spacer sections, making it possible to reduce running costs.

[0039] The structure and arrangement of the cutter and spacer parts are not limited to those shown in this embodiment. Other examples of the structure and arrangement of the cutter and spacer parts forming the crushing blade will be described below as second and third embodiments.

[0040] [Second embodiment] Fig. 3 is a schematic explanatory diagram (plan view) showing the structure of a crushing device in a second embodiment of the present invention, in which a drive motor and a casing are omitted. The crushing device 1B in this embodiment is different from the crushing device 1A in the first embodiment in that it has a crushing blade member 60a which is a member in which one cutter member 610b and one spacer member 620b are integrally provided. Note that, among the configurations of the crushing device 1B in this embodiment, the description of the same components as those of the crushing device 1A in the first embodiment will be omitted.

[0041] In this embodiment, one cutter member 610b and one spacer member 620b are integrally provided to form the crushing blade material 60a, and further, the cutter member 610a is arranged adjacent to the cutter member 610b of the crushing blade material 60a, and the spacer 610a is arranged adjacent to the spacer member 620b of the crushing blade material 60a, thereby forming the crushing blade 6.

[0042] Here, the cutter member 610b and the cutter member 610a have the same thickness, and adjacent cutter members 610a and 610b form a cutter section 61a (corresponding to n=2). Moreover, the spacer members 620b and 620a have the same thickness, and adjacent spacer members 620a and 620b form a spacer portion 62a (corresponding to m=2).

[0043] As shown in FIG. 3, in the crushing device 1B of this embodiment, the cutter member 610b and the spacer member 620b are integrated into a single member to form the crushing blade material 60a, so that the number of parts required to form the crushing blade 6 can be reduced to obtain a structure in which the number of adjacent unit units satisfies n=2 and m=2 (the same structure as the crushing blade 6 in the first embodiment).

[0044] [Third embodiment] Fig. 4 is a schematic explanatory diagram (plan view) showing the structure of a crushing device in a third embodiment of the present invention, in which a drive motor and a casing are omitted. The crushing device 1C in this embodiment differs from the crushing device 1B in the second embodiment in that crushing blade members 60a are disposed adjacent to each other to form crushing blades 6. Incidentally, among the configurations of the crushing device 1C in this embodiment, the description of the same configurations as those of the crushing device 1B in the second embodiment will be omitted.

[0045] In this embodiment, the crushing blade 6 is formed by arranging the cutter member 610b of one crushing blade member 60a and the cutter member 610b of the other crushing blade member 60a so as to be adjacent to each other. In the crushing device 1C in this embodiment, by changing the orientation of the crushing blade material 60a, a structure in which the number of adjacent units satisfies n=2 and m=2 (the same structure as the crushing blade 6 in the first embodiment) can be obtained. Therefore, the number of parts forming the crushing blade 6 can be reduced, and the workability in assembly can be improved.

[0046] As a modified example of this embodiment, the crushing blade 6 may be formed by arranging the spacer member 620b of one crushing blade member 60a and the spacer member 620b of the other crushing blade member 60a so as to be adjacent to each other. In addition, in the crushing device 1C of this embodiment, in order to adjust the distance between the cutter parts in the axial direction of the crushing blade 6, a cutter member 610a and a spacer member 620a may be provided at the ends of the drive shaft 5a and the driven shaft 5b, as shown in FIG.

[0047] Regarding the crushing device 1B in the second embodiment to the crushing device 1C in the third embodiment, the number (n) of adjacent cutter members 610a of the same thickness and the number (m) of adjacent spacer portions 620a of the same thickness have been described as being 2, but n and m may be 3 or more.

[0048] The above-described embodiment shows an example of the crushing device. The crushing device according to the present invention is not limited to the above-described embodiment, and the crushing device according to the above-described embodiment may be modified within the scope of the gist of the claims. [Industrial Applicability]
