Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compost turning-over device that takes in a compost raw material and drops it into small lumps to turn the compost raw material back.

[0002]

2. Description of the Related Art In the production of compost, so-called turning is carried out in order to increase the permeability of the deposited compost material and promote the maturation of the compost material. A general-purpose excavation / loading machine such as a loader (tractor shovel) is used, and a method is generally employed in which compost raw materials are scooped up in buckets and dropped little by little into small blocks.

[0003]

However, in the conventional method using the above-mentioned general-purpose excavating / loading machine, it is necessary to vibrate the bucket in small increments in order to drop the compost material into small lumps. In addition, the load on the machine is large, and in addition, the work requires skill and a great amount of work time, so that there is a disadvantage that the work efficiency is poor.

[0004] On the other hand, as disclosed in Japanese Patent Publication No. 7-67328, there is known a compost reversing device for dropping the compost raw material little by little by swinging an arm and a claw for gripping the compost raw material. However, in this configuration, there is a limit in dropping the compost raw material into fine small lumps, so that the effect of turning back cannot be sufficiently enhanced, and the driving operation is not easy to say. On the other hand, as disclosed in Japanese Patent Publication No. 6-76270, there is known an agitation turning-over device for agitating a compost raw material taken into a bucket with an agitation rod. Therefore, in order to make the compost material into small lumps and drop it smoothly and uniformly, it is necessary to always adjust the opening degree of the bucket while taking care not to apply an excessive load to the stirring rod with the compressed compost material. Yes, driving operation is troublesome. In addition, since the dedicated attachment needs to be mounted in place of the conventional bucket for the switching operation, the operation becomes inconvenient.

The present invention has been devised in order to solve such problems of the prior art, and it is possible to improve the efficiency of cutting back by dropping compost raw material into small chunks. The main objectives are to make the driving operation easy. Another object of the present invention is to easily attach to an existing work machine and to use it easily.

[0006]

In order to achieve the above object, according to the present invention, a lid for opening and closing an opening is pivotally mounted on a bucket containing a compost material supported by a base machine. The lid is provided with a discharge rotor for scraping the compost raw material in the bucket, and the compost raw material is taken into the bucket by closing the lid, and the discharge rotor is closed in a closed state with the lid down. Is rotated to drop the compost material into small lumps.

[0007] According to this, as compared with the conventional method in which the lightweight and spongy compost material is scooped only by the bucket, the compost material can be easily taken into the bucket.
When the compost material is dropped, the opening of the bucket is set downward, so that all the compost material in the bucket can be reliably discharged, and the work can be performed quickly and efficiently. In addition, it is only necessary to keep the lid closed at the time of dropping, and the driving operation is simple. Further, since the fall of the compost is prevented by the lid even if the opening of the bucket is not turned upward, there is also obtained an advantage that the work of loading the compost into the transporting vehicle, the compost dispersing device, or the like is made more efficient.

[0008] In particular, the discharge rotor in the compost turning device can have a configuration in which a plurality of scraping members are radially projected on the outer periphery of the rotating shaft. In this case, the compost material can be efficiently collected with a simple configuration. Can be scraped.

Further, the scraping member in the compost turning device may have a flat plate shape in the rotation direction, and may be configured to be capable of cutting the compost raw material. In this way, the compost raw material can be finely cut and scattered over a wide range, whereby the air permeability inside the piled compost is improved, and this is effective in promoting the fermentation of the compost.

[0010] Further, a plurality of the discharge rotors in the compost turning device may be provided, and a tip of the scraping member may be protruded to a position close to a rotation axis of the adjacent rotor. In addition to improving the efficiency of compost material discharge, the scraping member on the opposite side cuts and loosens compost material entangled with the rotating shaft,
It is possible to avoid a decrease in efficiency and malfunction due to winding of the compost material.

[0011] Further, the lid in the compost turning device may have a configuration in which a pawl that matches a pawl provided at an opening edge of the bucket is provided at a free end portion. When the compost raw material is sandwiched between the body and the compost raw material is taken into the bucket, even when the compost slab is made of concrete, the remaining compost raw material can be reduced, and the operation can be performed smoothly.

[0012] In the compost turning device, the discharge rotors may be provided in a pair in parallel in a direction along the opening of the bucket, and may be configured to be rotatable in directions opposite to each other. As compared with the configuration in which one discharge rotor is provided, the dropped compost raw material is deposited in a well-mixed state, and the effect of turning back can be enhanced. For example, if the two discharge rotors are rotated in the opposite directions so that the bucket side faces inward, the effect of stirring and mixing the compost materials in the bucket is obtained, while if the bucket side is rotated so that the bucket side faces outward. In addition, small lump of compost material can be scattered over a wide range.

The lid of the compost turning device can be configured to be detachably connected to a mounting portion of the bucket to a base machine together with a cylinder as a driving means for opening and closing the lid. ,
By removing the lid and the cylinder, normal bucket work becomes possible, and without replacing the entire bucket attachment, it is possible to switch between the turning work and the normal bucket work only by attaching and detaching the lid and the cylinder,
Easy to use. Moreover, it is only necessary to make relatively small changes such as mounting holes for connecting pins on buckets of existing excavating / loading machines such as wheel shovels and wheel loaders, thereby suppressing an increase in cost.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows a compost turning device constructed in accordance with the present invention. In this case, the bucket 4 of the wheel shovel 1 is provided with a lid 4 provided with a discharge rotor 3 for scraping out the compost material contained in the bucket 2.

However, the bucket 2 can be moved in a required direction by the raising / lowering operation of the boom 6 and the arm 7 and the turning operation of the upper turning body 8. ing.

The lid 4 is driven to open and close by a cylinder 10 pivotally attached to the bucket 2, and the lid 4 is closed as indicated by an arrow in FIG. Can be captured. Note that it is also possible to operate both the lid 4 and the bucket 2 to take in the compost raw material.

As shown in detail in FIG. 2, the discharge rotor 3 has a frame 12 provided with a mounting portion 11 for the bucket 2.
A pair is provided in parallel with each other in a direction along the opening of the bucket 2. The discharge rotor 3 includes a rotating shaft 14 whose both ends are supported by the frame 12 via a bearing 13, and a plurality of scraping members 15 radially protruding from the outer periphery of the rotating shaft 14. The attachment part 11 is provided with a connection part 16 with the end 10 a of the cylinder 10 and a connection part 17 with the bucket 2. As shown in FIG. 3, a connecting portion 17 for connecting the bucket 2 to the other end 10b of the cylinder 10 is pivotally connected to a mounting portion 2b of the bucket 2 with respect to the arm 7 via a connecting pin or the like.

The rotating shaft 14 of one discharge rotor 3 is driven to rotate by a motor 21 via a pair of sprockets 18 and 19 and a chain 20. The rotating shaft 14 of the other discharge rotor 3 rotates in the opposite direction in conjunction with one rotor 3 via a pair of gears 22 and 23 meshing with each other.

The scraping member 15 is formed in an arcuately curved shape and in the shape of a flat plate in the direction of rotation, and can be cut when scraping the compost material, whereby the compost material is finely chopped. It is discharged from the discharge rotor 3 in a state where it is removed. For this reason, the air permeability inside the deposited compost is improved, which is effective in promoting the fermentation of the compost. In addition,
It is also possible to form the side edge of the scraping member 15 into a sharp blade shape in order to enhance the cutting ability of the compost material.

The scraping members 15 are arranged at predetermined intervals in the axial direction of the rotating shaft 14 and sequentially shifted from the projecting positions by a predetermined angle in the circumferential direction. Here, a total of six scraping members 15 are provided on each rotating shaft with the projecting positions shifted by 120 degrees.

The scraping member 15 has a tip protruding to a position close to the rotating shaft 14 of the adjacent rotor 3, whereby the compost material entangled with the adjacent rotating shaft 14 is cut and loosened. It is possible to avoid a decrease in efficiency and a malfunction due to the winding of the compost material around 14.

At the free end of the frame 12, there is provided a claw 26 which is aligned with a claw 25 provided at the opening edge of the bucket 2, whereby the compost material is sandwiched between the bucket 2 and the lid 4. When the compost raw material is taken into the bucket 2, the remaining compost raw material can be reduced even when the compost slab is made of concrete, and the operation can be carried out efficiently.

The compost material taken into the bucket 2 as described above is turned into a small lump by rotating a pair of discharge rotors 3 in a closed state with the lid 4 down as shown in FIG. Is dropped. At this time, by rotating the pair of discharge rotors 3 in directions opposite to each other and with the bucket side facing inward as shown by the arrow in FIG. The compost material is discharged in a state of being finely cut. The discharge rotor 3
Can be rotated in the direction opposite to the arrow in FIG. 3, that is, so that the bucket side faces outward. In this case,
The compost raw material is discharged from a portion outside the rotation shaft 14 of both discharge rotors 3.

Although an example in which the present invention is applied to a wheel shovel has been described above, the present invention is not limited to this, and is widely applied to an excavating / loading machine having a bucket whose opening can be directed downward. It is possible.

For example, as shown in FIG. 4, the present invention may be applied to a wheel loader 31. In this case, a lid 34 having a discharge rotor 33 having substantially the same configuration as that described above may be pivotally mounted on the upper part of the bucket 32, and the compost material A can be taken into the bucket 32 by closing the lid 34. . In order to drop the compost raw material stored in the bucket 32 into small lumps, as shown by imaginary lines in FIG.

In the above embodiment, a pair of discharge rotors are provided in parallel in the direction along the opening of the bucket. However, one or three or more discharge rotors can be used. It is possible to arrange a plurality of rows in the discharge direction, but a sufficient effect can be obtained with the above configuration. Further, here, the rotation axis of the discharge rotor is arranged so as to be parallel to the pivot axis of the lid, but it is also possible to arrange the discharge rotor in a direction orthogonal thereto. In addition, a plate material having a curved shape is used for the scraping member, and the protruding positions are shifted by 120 degrees to provide a total of six plates. However, the shape, the protruding angle, and the number of arrangement of the scraping member are as follows. The material is not limited to this, and may be appropriately selected according to the type of the compost raw material and the like. For example, in order to enhance the scraping function of the compost material, a strip having a twisted shape or a widened portion formed at the tip or the like is also possible.
