Description

DETAILED DESCRIPTION OF THE INVENTION (Object of the Invention) The present invention is directed to a ground where rubble or rock guard foreign matter is scattered and mixed and is still undulating, such as a demolition construction site, a construction site, a cultivated land, etc. This is related to the leveling bucket required for leveling to a flat ground, and it can be mounted on the tip of the arm of a construction machine such as a backhoe to enable leveling work while removing debris and rocks in the earth and sand. It is intended to provide a versatile leveling bucket.

(Prior Art) If the uneven ground is simply leveled, bulldozers such as straight dozers and angle dozers, carriors and the like can be used to easily perform leveling work.
However, if the ground is not only undulating, but foreign matter such as rubble and rocks is mixed in the soil and it is necessary to remove these foreign matter and level the ground, attach a ripper to the bulldozer. First, dig up the ground to float the foreign matter in the soil, and if there is a large foreign matter, operate the tractor shovel or the bucket of the backhoe to collect the foreign matter such as debris and rocks in one place and dispose of it appropriately. Good, but if small debris and rocks are scattered around the soil, it is not always easy to remove them.

In such a ground, a dedicated sieve bucket whose bottom plate part of a normal bucket is formed on the fork part is attached to the arm of the backhoe, and the fork part is inserted into the sand and scooped up to remove foreign matter in the sand. Need to be screened.
Although it is possible to remove foreign matter with such a special bucket, depending on how large of scattered foreign matter is to be removed, the fork part depending on the size of the foreign matter to be removed beforehand may be used. It will be useless unless several kinds of formed sieve buckets are prepared. Moreover, since this bucket is of course exclusively used for sieving work, it is impossible to proceed with ground leveling work in parallel from the sequentially removed parts while removing foreign matter, and therefore, from the necessary location. If you try to parallel the grading work sequentially, either introduce a construction machine other than the backhoe with a sieve bucket, or remove the sieve bucket from the construction machine with a sieve bucket and make it a convenient bucket for grading. It is impossible to carry out without replacing the work.

However, in reality, even if there is a site that requires the above-mentioned work, unless it is a special large-scale project, it is also possible to introduce many construction machines to one site at the same time. For example, it is almost impossible to replace the buckets with different types of buckets each time and proceed with the work, so work to remove debris and rocks from the soil and level the ground. The reality is that work is separated and digested in separate steps.

In view of the above situation, the present invention is capable of sequentially performing ground leveling work while removing foreign matters in the earth and sand such as debris and rocks with a bucket attached to one backhoe, and immediately continues. It is a versatile and convenient bucket that can be moved to the foreign matter removal work on the ground beside it, and then to the ground leveling work again, and the mesh size for sieving can be changed according to the size of the foreign matter to be removed. The development of a new bucket called "," and finally succeeded in realizing it individually, and the details of its configuration will be explained below.

(Structure of the Invention) As can be clearly understood from the typical embodiment shown in the drawings, the leveling bucket of the present invention has left and right side plates 2,2 and a bottom plate 3 arranged between the side plates 2,2. , A back plate 4 for connecting and integrating the upper ends of the left and right side plates 2, 2 and the bottom plate 3 and an arm connecting portion 5 outside the back plate 4 to form a bucket body, and The fork members 11, 11, ... Extend in parallel to form the fork portion 1, and among the many fork members 11, 11 ,.

Fork part 1 extended from the upper end of the back plate 4 of the bucket body
Is one of the many fork members 11, 11, ...
The stationary ones are fixed to the back plate 4, and the remaining ones are formed as movable fork members 11 ', 11', ... Which can move in parallel to a predetermined range between the fixed fork members 11, 11 ,. , By moving these movable fork members 11 ', 11', ... in parallel, the adjacent spacing between the fixed fork members 11, 11, ... can be changed to scrape or scoop like a rake (or rake). The sieving range of foreign matter in the earth and sand such as debris and rocks to be removed can be appropriately selected.

The parallel movement of the movable fork members 11 ', 11', ... is achieved by moving the movable forks to the left and right side plates 2, 2 and the horizontal rod 6 formed by penetrating the fixed fork members 11, 11 ,. The members 11 ', 11', ... Are integrated by welding or other means, and the horizontal rod 6 is attached to any one of the side plates 2 other than some means, for example, the means shown in the embodiments described later. A handle formed with a female screw is rotatably mounted, the male screw portion of the horizontal rod 6 is screwed into the female screw portion, and the handle is rotated, so that there is no step on the left and right of the horizontal rod 6. Any known parallel moving means can be adopted, such as making parallel movement, or mounting a hydraulic device or other appropriate power source on any one of the horizontal rods 6 and forcibly moving by actuation of the power source. .

In order to stabilize the parallel movement of the movable fork members 11 ', 11', ..., Auxiliary horizontal rods 6'are arranged in parallel to the horizontal rods 6 as in the illustrated embodiment, so to speak, a plurality of horizontal rods 6 are provided. It is desirable to adopt a configuration such that Further, although not shown in the figure, a reinforcing rod welded and fixed to the fork members 11, 11, ..., which are fixed in reverse, is provided laterally around the middle of the fork members 11, 11 ,. The movable fork members 11 ′, 11 ′, ... Corresponding to the horizontal position of the movable fork member 11 ′, 11 ′, ... Are provided with slightly larger through holes, and the reinforcing rods are inserted through the through holes. It is possible to reinforce the strength of the entire fork portion 1 without hindering the parallel movement of ', 11', ....

The configuration of a preferred embodiment shown in the drawings will be specifically described below.

(Embodiment 1) This example is one of the specific examples for realizing the parallel movement of the movable fork members 11 ′, 11 ′, ... In the leveling bucket of the present invention in which the horizontal rod 6 for moving the movable fork members 11 ', 11', ...
Each of the left and right side plates 2, 2 is protruded from the outer surface, and is made longer by a length corresponding to the parallel movement width, and the stators 61, 61 are integrally formed at the respective end portions, while being moved in parallel. The regulators 7 and 7 capable of selectively filling the gap between the stator 61 and the side plate 2 when they are shifted to the left or right are formed on the outer sides of the left and right side plates 2 and 2, respectively. It is a leveling bucket.

In this embodiment, as shown in the enlarged perspective view of the main part of FIG. 3, an auxiliary horizontal rod 6'is formed parallel to the lower side of the horizontal rod 6 and is formed at each end. Stator 61,61
Has a structure in which the horizontal rod 6 and the auxiliary horizontal rod 6'are integrated over the horizontal rod 6 and the auxiliary horizontal rod 6 '.

Further, in the configuration shown by the solid line in the figure, the horizontal rod 6 (and the auxiliary horizontal rod 6 ') is moved to the leftmost position, and the position of the movable fork member 11' is exactly the same as that of the fixed fork members 11, 11. The structure is shown when the range of the fork unit 1 located in the middle is minimized. A front view of the fork portion 1 corresponding to this state is shown in FIG. 5 as a front view with a part omitted.

In the configuration shown by the chain double-dashed line in FIG. 3, the horizontal rod 6 (and the auxiliary horizontal rod 6 ') is moved to the right (in the direction of arrow a), and the stator
This figure shows a state in which a gap is formed between 61 and the side plate 2. Due to this movement, the movable fork members 11 ′, 11 ′, ... Which are naturally integrated are also parallel to the direction of arrow b. The distance between the side of the fork member 11 that has moved and moved in parallel and the side of the fork member 11 on the opposite side is larger than the distance before the parallel movement, and the sieving range is expanded accordingly. The restrictor 7 rotatably attached to the side plate 2 is rotated and fitted into the gap between the stator 61 and the side plate 2 formed in this manner as indicated by the arrow c, whereby the horizontal rod 6 ( The movement of the auxiliary horizontal rod 6 ') to the left side is restricted, and the movable fork members 11', 11 ',
The parallel movement of ... Is fixed and the bucket is realized in the state shown in the front view of the fork portion 1 side, which is partially omitted in FIG.

In addition, when changing to the configuration displayed by the two-dot chain line,
The restrictor 7 attached to the left side plate 2 (not shown) is removed from the gap, and the right side plate 2 is exactly shown by the solid line in FIG.
To the same condition as the regulator 7 attached to the left side, and hit the left side regulator 7 (not shown) with a hammer, or pry a burr between the right side regulator 7 and the right side plate 2. The horizontal rod 6 (and the auxiliary horizontal rod 6 ') is moved to the right in the direction of arrow a.

In this embodiment, by removing the left and right restrictors 7, 7,
It is possible to select the sieving range in two stages.

(Effects) The leveling bucket of the present invention having the above-mentioned configuration,
Since the fork portion 1 capable of changing the sieving range is combined with the bucket body having substantially the same structure as the ordinary bucket, foreign matters of various sizes are mixed and the scattered ground is grounded. At this time, the movable fork members 11 ′, 11 ′, ... Are adjusted in parallel so that the distance between the fork members according to the size of the foreign matter to be removed is adjusted, and the fork portion 1 is dragged or cut into the ground to remove the foreign matter. Carry out the work. If it is necessary to immediately level the range from which debris and rocks have been removed by this foreign matter removal work, immediately after the foreign matter removal work, the bucket body side is leveled to finish the ground leveling work within a predetermined range. Further, immediately after that, the foreign matter removing operation can be performed again by the fork portion 1.

Therefore, unlike the prior art, it is not necessary to replace the buckets one by one in accordance with the work content, and extremely efficient ground leveling work can be performed.

In particular, the parallel movement adjustment of the movable fork members 11 ', 11', ... is performed by the stator 6 formed at both ends of the left and right side plates 2, 2 and the horizontal rod 6.
With the structure that is realized by selectively inserting and removing the restrictor 7,7 between the contact hole 1 and 61, adjustment of the fork gap can be extremely simple and stable, and the above-mentioned effect is further promoted. It has been done.

As mentioned above, the leveling bucket of the present invention can exert great power for ground leveling work of uneven ground mixed with debris and rock foreign matter, and is relatively easy to manufacture in terms of configuration. Since it can be provided at low cost, it is expected that the civil engineering personnel who need this kind of civil engineering work will be highly evaluated.
