[Prior art]
A lot of various industrial wastes, such as asphalt waste and concrete waste, are discharged during road repairs and demolition of buildings, which has become a social problem. In the past, many were disposed of for landfill, but now many are recycled from the viewpoint of environmental conservation. In particular, since waste materials such as concrete are large in amount and can be mostly reused, the reuse thereof is strongly desired.
[0003]
The role of the bucket of the civil engineering machine for directly treating these waste materials is large. Some civil engineering machines not only collect raw materials such as waste materials, transport them to other places, and replace them, but also have a function of crushing raw materials in a collection process in a bucket. However, there is no configuration in which a second bucket is provided as an auxiliary to the bucket. As an example of a simple method of crushing waste material in a bucket, a method in which various crushing devices are provided in a bucket has been proposed.
[0004]
As these examples, there is known a method in which a pair of crushing machines for pinching and crushing waste materials such as concrete blocks scooped into a bucket are detachably provided, and the waste materials are scooped, crushed and discharged as they are (for example, , Patent Document 1). There is also known a bucket in which an operating body provided with crushing teeth is reciprocally movable to crush concrete waste material with a fixed crushing tooth provided in the bucket (for example, Patent Document 2). In addition, a pair of rotating shafts are provided in a scooping device in a bucket, and large, medium, and small crushing tooth plates are attached to each rotating shaft, and a concrete plate is crushed into small pieces by rotating the rotating shaft. (For example, Patent Document 3).

BEST MODE FOR CARRYING OUT THE INVENTION
[Embodiment 1]
Hereinafter, Embodiment 1 of the present invention will be described with reference to the drawings. FIG. 1 is an overall view of a backhoe (civil engineering machine) to which the present invention is applied, FIG. 2 is a cross-sectional view of a bucket of the present invention, and FIG. 3 is a front view of the bucket of the present invention. FIG. 4 is a front view of the bucket of the present invention, showing a state in which a raw material such as a material to be crushed is being thrown into the crushing bucket from the throwing bucket.
[0015]
The backhoe 1 is a civil engineering machine of the same system as a power shovel, and is a publicly known excavator. It is generally applied to excavation of the ground at a lower position than the machine, and is suitable for work such as digging holes and trenches. Machine capacity is represented by bucket capacity. The backhoe 1 is self-propelled and can be moved to any position via a crawler 2. A first turning arm 4 is provided on a base 3 via a support shaft (not shown), and is raised and lowered in a direction of an arrow A (vertical direction) about the support shaft by a first cylinder (up-and-down cylinder) 5.
[0016]
A second turning arm 6 is provided at the tip of the first turning arm 4 via a support shaft 6a, and is turned around the support shaft 6a in the direction of arrow B by a second cylinder 7 provided on the first turning arm 4. Operate. An end of the bucket 9 is swingably provided at a tip of the second swing arm 6 via a support shaft 15. The bucket 9 includes a crushing bucket 10 and a charging bucket 11. The second swing arm 6 is provided with a bucket cylinder 8, and the tip of a piston rod of the bucket cylinder 8 is attached to a bucket body 10 a of the crushing bucket 10 via a shaft 18 so as to be relatively rotatable (swinging). . That is, the bucket body 10 a swings about the support shaft 15 in the direction of arrow C by the expansion and contraction driving force of the bucket cylinder 8.
[0017]
Further, the base 3 is configured to be capable of turning in the horizontal direction. Therefore, the bucket 9 can be moved to any position in the turning range and its direction can be changed. A throwing bucket 11 is provided on a bucket body 10a of the crushing bucket 10 via a support shaft 16 so as to be swingable in the direction of arrow D. The charging bucket 11 is for scooping up crushed objects (excavated objects) such as asphalt waste and concrete lump, and collecting the crushed objects inside the bucket body 10a.
[0018]
The bucket body 10 a of the crushing bucket 10 does not necessarily input all the raw materials through the input bucket 11. For example, when scooping a pile of raw materials in a normal bucket configuration in which the bottom is not open, two buckets are used at the same time and a large amount of raw materials can be transported, which is efficient. When the raw materials collected in the bucket body 10a are transported so as not to be spilled, the charging bucket 11 can be used as a lid.
[0019]
Hereinafter, Embodiment 1 will be described as a bucket having a discharge port at the bottom of the bucket body 10a and crushing the input raw material. At the outlet, a roster such as a grid or a net is arranged (not shown). This rostral discharges only particles of a certain size or less, and those that are not crushed remain in the crushing chamber 28 of the bucket body 10a and are crushed again. A link 13 rotatably connected by a support shaft 14 and a support shaft 17 is provided between the second swing arm 6 and the input bucket 11.
[0020]
The second swing arm 6, the bucket main body 10a of the crushing bucket 10, the input bucket 11, and the link 13 constitute an interlocking means including a four-joint link mechanism having the support shafts 14, 15, 16, and 17 as nodes. As the bucket body 10a of the crushing bucket 10 swings about the support shaft 15 in the direction of arrow C by the driving force of the bucket cylinder 8, the input bucket 11 swings about the support shaft 16 in the direction of arrow D. I do.
[0021]
An input port 26 is provided at an upper portion of the crushing bucket 10 on the input bucket 11 side of the bucket body 10a. The rotor shaft 20 is rotatably provided on the bucket body 10a of the crushing bucket 10, and is driven via a drive motor (not shown) disposed outside the bucket body 10a or a speed reducer driven by the drive motor. A rotor disk 22 is fixed to the rotor shaft 20, and the rotor shaft 20 and the rotor disk 22 constitute a crushing rotor and rotate integrally.
[0022]
On the outer periphery of the rotor disk 22, one or a plurality of (equal-angle intervals equal to four circumferential parts in this embodiment) impacting members 21 are detachably fixed. The striking member 21 is formed of a hard and wear-resistant material. The striking member 21 has a square block shape, and when the striking surface is worn, the striking member 21 can be removed and turned over to make the mounting surface a striking surface. The striking member may be a hammer type.
[0023]
The inside of the bucket body 10a of the crushing bucket 10 constitutes a crushing chamber 28 for crushing the crushed material 30 charged in the partitioned space. The inner wall of the crushing chamber 28 is coated with a hard material having abrasion resistance. A first repulsion member 24 and a second repulsion member 25 are detachably fixed to a part of the inner wall. The first repulsion member 24 and the second repulsion member 25 are arranged along the outer circumference of the crushing rotor.
[0024]
The crushing rotor to which the striking member 21 is attached, the first repulsion member 24, the second repulsion member 25, and the like constitute a so-called impact-type crusher (impact crusher), and are also referred to as impact crushers, hammer crushers, and the like. It is what has been. In the first embodiment, an example in which two repulsion members are provided is described. However, one or more repulsion members may be provided.
[0025]
The first repulsion member 24 and the second repulsion member 25 are made of a hard and wear-resistant material. Further, the first repulsion member 24 and the second repulsion member 25 may be divided instead of being integrated. The divided repulsion member can be replaced only at a portion where remarkable wear has occurred. Further, in the first embodiment, the first repulsion member 24 and the second repulsion member 25 are described as having a flat plate shape, but may have a curved surface shape. At the lower part of the bucket body 10a of the crushing bucket 10, a discharge port 27 which is an opening formed for discharging the crushed object 30a is provided.
[0026]
[Crushing method]
Next, a method of crushing the object to be crushed in the bucket 9 of the present invention will be described. The crushed material is scooped up by the charging bucket 11 and collected as shown in FIG. A crushing rotor composed of the rotor shaft 20, the rotor disk 22, and the like is rotated in a direction indicated by an arrow E at a predetermined rotation speed by driving a drive motor. When the crushing bucket 10 is swung in the direction of arrow C 'by the driving force of the bucket cylinder 8, the input bucket 11 is also swung in the direction of arrow D' by the four-node link mechanism (see FIG. 4).
[0027]
Then, the crushed material 30 collected in the charging bucket 11 is charged into the crushing chamber 28 from the charging port 26 of the bucket body 10a of the crushing bucket 10 as shown in FIG. The crushed object 30 hits the striking member 21 and is accelerated by striking. The accelerated crushed object 30 collides with the first repulsion member 24 and is repelled. The crushed object 30 is crushed by the impact force in the impact process and the impact force in the collision process, and the crushed object 30 is crushed.
[0028]
The crushed object 30 collides with another crushed object 30 that has been hit and accelerated by the next striking member 21 in the crushing chamber 28 and is crushed by each other. A similar crushing process is performed between the crushing rotor to which the impact member 21 is attached and the second repulsion member 25. Thus, since the crushed object 30 is crushed by the impact force, efficient crushing can be performed. That is, the drive motor for driving the crushing rotor does not need to be so large, and can be made suitable as a crushing device built in the crushing bucket 10.
[0029]
The crushed object 30 a crushed to a predetermined size or less in this manner is discharged from the discharge port 27. Since the rostor is disposed at the discharge port 27, only particles having a certain size or less are discharged, and those that are not crushed remain in the crushing chamber 28 of the bucket body 10a and rotate together with the crushing rotor to be crushed again. If, for some reason, the particles cannot be crushed to a predetermined size or less, the first turning arm 4, the second turning arm 6, the bucket 9 and the like are turned or rocked so that the input port 26 is moved downward. The crushed material may be discharged from the upper inlet 26 side.
[0030]
In the first embodiment, the interlocking means has been described as a four-bar linkage. However, a chain / sprocket mechanism, a gear train, and the like may be provided between the support shafts 15 and 16 for interlocking. Good. Further, the bucket 9 has been described as being constituted by the crushing bucket 10 having the opening (discharge port) at the bottom and the charging bucket 11, but the crushing bucket 10 and the charging bucket 11 having no opening at the bottom are used. It may be configured.
[0031]
[Embodiment 2]
5 and 6 are diagrams showing a second embodiment of the bucket of the civil engineering machine. In the first embodiment described above, the crushing bucket 10 and the charging bucket 11 are linked by a four-node link mechanism. The bucket of the earth-moving machine shown in FIGS. 5 and 6 swings the input bucket 11 by a swing drive unit. FIG. 5 is a front view of the bucket according to the second embodiment, showing a state in which a raw material such as a material to be crushed can be scooped up by a charging bucket. FIG. 6 is a front view of the bucket according to the second embodiment, and shows a state in which a raw material such as an object to be crushed is charged from the charging bucket to the crushing bucket. The same members as those in the first embodiment are denoted by the same reference numerals, and redundant description will be omitted.
[0032]
The bucket 9 includes a crushing bucket 10 and a charging bucket 11. A throwing bucket 11 is provided on a bucket body 10a of the crushing bucket 10 via a support shaft 16 so as to be swingable in the direction of arrow D. An inlet 26 and an outlet 27 are provided in the bucket body 10a. In the outlet 27, a roster such as a lattice or a net is arranged (not shown). In the crushing chamber 28 of the bucket body 10a, a crushing rotor including a rotor shaft and a rotor disk 22a is rotatably provided. On the outer periphery of the rotor disk 22a, a plurality of (in the second embodiment, angular intervals equal to 12 circumferential parts) crushing teeth 21a are detachably fixed.
[0033]
Unlike the hitting member 21, the crushing teeth 21a are crushed mainly by compression, bending and wedge action, not by hitting. Therefore, the crushing teeth 21a are different from the above-described striking member 21 in the shape and the like of the teeth, the number of the crushing teeth 21a is different, and the rotation speed during operation is different. Further, a repulsion member 24a is detachably fixed to a part of the crushing chamber 28. The object to be crushed into the crushing chamber 28 is crushed by a crushing tooth 21a and a repulsion member 24a attached to a crushing rotor rotating at a predetermined rotation speed by driving a drive motor (not shown). That is, the crushing process of the material to be crushed is performed by compression, bending, wedge action, or the like on the input raw material due to the interaction between the crushing teeth 21a and the bucket body 10a or the interaction between the crushing teeth 21a and the repulsion member 24a.
[0034]
An attachment portion 10b is formed outside the bucket body 10a. A mounting portion 11a is also formed outside the input bucket 11. A clevis-type fluid pressure cylinder (drive body) 51 is provided between the mounting portion 10b and the mounting portion 11a. That is, the main body of the fluid pressure cylinder 51 is attached to the attachment part 10b so as to be swingably rotatable. Further, a piston rod 52 of the fluid pressure cylinder 51 is mounted to be swingably rotatable relative to the mounting portion 11a.
[0035]
By moving the piston rod 52 of the fluid pressure cylinder 51 forward and backward, the charging bucket 11 swings around the support shaft 16 in the direction of arrow D. That is, the throwing bucket 11 moves the piston rod 52 in the reducing direction to a position where the crushed object is scooped (the state of FIG. 5), and the bucket body 10a in which the piston rod 52 is moved in the extending direction moves the crushed object to the bucket body 10a. It swings to the input position (the state of FIG. 6). As described above, when the swing driving device 50 for the input bucket 11 is separately provided, the degree of freedom of the operation of the input bucket 11 is increased, and operations such as a scooping operation and an input operation are facilitated.
[0036]
7 and 8 are diagrams showing another example of the driving device for swinging the throwing bucket 11. FIG. 7 is a front view of the bucket, showing a state in which a raw material such as a material to be crushed can be scooped up by the input bucket. FIG. 8 is a front view of the bucket, showing a state in which a raw material such as a material to be crushed can be charged from the charging bucket to the crushing bucket.
[0037]
A support shaft 16a is provided rotatably with respect to the bucket body 10a. The support shaft 16a and the input bucket 11 are provided so as to rotate integrally. The support shaft 16a is formed with a crank portion 16b that rotates integrally. A clevis-type hydraulic cylinder 51 is provided between the crank part 16b and the mounting part 10b. That is, the main body of the fluid pressure cylinder 51 is mounted so as to be relatively rotatable with respect to the mounting portion 10b. Further, a piston rod 52 of the fluid pressure cylinder 51 is attached to the crank part 16b so as to be relatively rotatable. By moving the piston rod 52 of the fluid pressure cylinder 51 forward and backward, the charging bucket 11 swings around the support shaft 16a in the direction of arrow D. This example shows a state in which a part of the inside of the bucket body 10a is partitioned and a fluid pressure cylinder 51 is installed.
[0038]
In the second embodiment, the description has been given assuming that the drive device for swinging the input bucket uses a hydraulic cylinder, but other drive bodies such as a drive motor and a swing type actuator (torque actuator) are used. Needless to say, what is done can be applied.
[0039]
[Embodiment 3]
9 and 10 are diagrams illustrating a third embodiment of a bucket of a civil engineering machine. In the first and second embodiments described above, the raw material as the crushed object or the like is dropped into the crushing chamber by its natural weight, and the raw material as the crushed object or the like that has fallen is rotating. It was hit with a member. The bucket of the civil engineering machine shown in FIGS. 9 and 10 is provided with a pressing member for forcibly pressing a raw material, such as a crushed object, on a side of a crushing rotor to which a striking member is attached. 9 is a front view of a bucket provided with a pressing member, and FIG. 10 is a side view of FIG. In the third embodiment, the basic form of the bucket is the same as that of the second embodiment. The same members as those in the second embodiment are denoted by the same reference numerals, and detailed description is omitted.
[0040]
The pressing member 60 is swingably provided on the bucket body 110 of the bucket 9. A stopper 65 is formed on the bottom side of the bucket body 110 to regulate the range in which the pressing member 60 can swing toward the crushing rotor. One end of the pressing member 60 is supported by the shaft 61, and the pressing member 60 is swingably provided on the bucket body 110. The pressing member 60 has a part on the other end side protruding outward from the bucket body 110, and the other end protruding from the bucket body 110 is a tip part 62.
[0041]
The pressing member 60 swings inside the bucket main body 110 around the shaft 61 in a state where a part thereof protrudes from the bucket main body 110 in the direction of arrow E. An intermediate portion of the pressing member 60 is a raw material pressing portion 63 that comes into contact with and presses the material to be crushed (raw material) 30, and is formed in a lattice shape as shown in FIG. The crushed object 30 larger than the interval between the lattices is pressed against the crushing rotor to which the crushing teeth 21a are attached.
[0042]
That is, the distal end portion 62 of the pressing member 60 is moved from the free state (the state indicated by the two-dot chain line in FIG. 9) to the ground by the operator operating the backhoe (civil engineering machine) 1. When it is brought into contact with a fixing surface such as G, it swings to the state shown by the solid line in FIG. In this manner, the crushing teeth 21a strike the crushed object 30 in a state where the pressing member 60 forcibly presses the crushed object 30 against the crushing rotor, so that the crushing process can be performed efficiently and reliably.
[0043]
In the third embodiment, the description will be made assuming that the pressing member presses the crushed object 30 loaded into the crushing chamber 28 against the crushing rotor by bringing the distal end portion 62 into contact with a fixed surface such as the ground G. However, it is not limited to this. The crushing object may be pressed against the crushing rotor side by swinging the pressing member by the driving body.
[0044]
Also, the description has been given assuming that the shape of the raw material pressing portion of the pressing member is a lattice shape, but a crushed material (raw material) having a predetermined size or more can be pressed, and a crushed material (raw material) smaller than that passes. Any shape can be used as long as it can be formed. Further, the description has been made of an example in which the present invention is applied to a bucket having no input bucket. However, it is needless to say that the present invention can be applied to a bucket having an input bucket.
[0045]
【The invention's effect】
As described above in detail, in the present invention, the feeding bucket is provided in the crushing bucket, so that the transport efficiency of the raw material is improved, and the raw material can be efficiently supplied to the crushing bucket having the built-in crushing device. Further, by providing the charging bucket, an optimal amount of the raw material can be charged into the crushing bucket having the crushing device.
[0046]
Further, when the crushing processing capacity is exceeded, it can be returned from the inlet port side, so that handling and maintenance are facilitated. Further, with the provision of the interlocking means of the crushing bucket and the charging bucket, a driving body is not required for driving the charging bucket, the structure can be simplified, and the maintenance is facilitated. Further, when the throwing bucket is swung by the swing driving device, the degree of freedom of the operation of the throwing bucket is increased, and the operation is facilitated.
[0047]
In the case where the pressing member is provided on the bucket, the raw material is forcibly pressed against the crushing rotor, and the crushing process is performed by hitting the striking member with the material, so that the crushing process can be performed more efficiently.
