Description

[Detailed description of the invention] <Industrial application field> This invention relates to a mini excavator with a grounded container. <Conventional technology> Recently, it is different from a conventional excavator as a general civil engineering machine. Extremely small excavators called ultra mini excavators have begun to spread, and there are riding or walking types. These super mini construction machines are used for small-scale partial maintenance of farmland, partial construction such as laying in the back alleys or alleys where general construction machinery cannot enter, or in narrow places such as home plumbing, or water pipes in golf courses. It can be easily operated by workers other than specialized operators.

<Problems to be Solved by the Invention> In the mini-construction machines described above, piles are generally piled on the sides of the excavated soil grooves, and are later leveled by blade work. However, you may want to move some of this soil to another location as needed.

In such a case, it is often difficult for the blade to work due to soil spilling during the movement.

Particularly, in the case of a super mini construction machine, the width and height of the blade are small, and the ability to push and move a large amount of soil at once is small, so this type of work is very inefficient.

<Means for Solving the Problems> The present invention is to solve the above-mentioned work by providing a specially designed container in the blade portion, and supports a bucket 12 working machine at one end of the machine body 1. In a mechanism provided with a blade 17 working machine that is supported at the end of the boom 6 side and is vertically moved and oscillated by the end arm 14 of the body 1 on the boom 6 side,
At the tip end of the arm 14, a bottom plate 19 is grounded substantially horizontally along the ground side, and a bucket 12 is provided from above.A container 18 capable of receiving and storing soil excavated by a working machine and scooping up soil on the ground side.
A notch recess is provided at a substantially central position of the tip of the bottom plate 19 of the container 18 to allow the tip of the bucket 12 to pass therethrough.
26 is formed.

<Operation> The soil excavated or scooped by the bucket 12 is
The container is dropped and accommodated in the container 18 mounted above and in an upward posture, carried by a mini shovel to a predetermined location, or after a predetermined operation after excavation is completed, the soil is scraped into the interior by a scoop hoe or the like and discharged.

The concave portion 26 at the tip of the container allows the bucket 12 to pass so as not to hinder excavation of soil at a position closer to the body 1. The container 18 is moved forward with its bottom along the ground to scoop up the soil deposited on the ground, and if necessary, raise the arm 14 to move the body 1 to convey the soil to a predetermined location. Can also be discharged.

<Embodiment> FIGS. 1 to 3 show one embodiment of the present invention for a walking type super mini excavator.
A bonnet 3 with a built-in drive unit such as an engine
The lower part of the frame 2 has a traveling part 5 composed of left and right crawlers. At the center of the front end of the frame 2, a base end of a boom 6 is pivotally supported with a boom cylinder 7 via a support 4 so as to be able to swing back and forth. 9 is pivotally supported, and the tip of the bucket arm 9 has a bucket arm 9
An excavating bucket 12 driven by a bucket cylinder 11 attached along is provided rotatably via a drive link 13.

A blade arm 14 and a blade cylinder 16 arranged side by side above and below the middle part of the left and right running parts 5 project forward of the fuselage, and a blade 17 is detachably attached to the tip of the blade arm 14. The mechanism swings up and down.

Reference numeral 18 denotes a container for soiling that is detachably attached to the blade 17, a bottom plate 19 made of a horizontal rectangular plate, a back plate 21 rising on the back side, and an upper side inclined downward toward the front on both left and right sides. Right and left triangular side plates
At the upper end of the back plate 21, an attaching portion 23 having a channel shape in the opposite direction to cover the upper end of the blade 17 is connected, and the container 18 is detachably attached to the blade 17 by bolts 24. Mechanism.

In the center of the tip of the bottom plate 19, a cutout recess 26 is formed so that the bucket 12 can be excavated closer to the fuselage with the container 18 attached, and the bucket 12 passes vertically through the recess 26. Are allowed to do so.

When the work is performed by the above configuration, first, excavation of the front of the fuselage is performed with the bucket 12 in the state shown in FIGS. 1 and 3, and when the excavated soil is stored in the container 18, the bucket 12 is turned over on the container 18. To drop the soil into the container 18. The soil contained in the container 18 in a predetermined amount is raised on the container 18 to move the aircraft to a predetermined place, and after the container 18 is lowered again or after excavation the soil is returned to the original position, on the spot, It is scraped out from the inside by a hoe or scoop and discharged.

4 and 5 show another embodiment of the present invention. In this embodiment, the back plate 21 of the container 18 is inclined backward in two steps as shown in FIG. A bracket 27 protruding rearward on the back of the blade arm directly
Removably attach to 14 tips. In the attached state, the left and right sides of the upper portion 21b of the rear plate 21 form rearwardly extending 21c, 21c so as to cover the front portion of the body 1;
A forward-facing concave portion 28 is formed between the extending portions 21c, 21c to house the lower end of the boom 6 so as to surround the lower end of the boom 6, and covers a lower mechanism such as a cylinder in front of the fuselage for excavated soil to fall. At the same time, the concave portion 28 does not prevent the boom 6 from swinging.

<Effect of the invention> Since the invention is configured as described above, the soil excavated by the bucket is dropped and stored in a container below the boom as it is,
After a predetermined amount of excavated soil is stored, it can be transported to a location away from the site and easily discharged, or the excavated soil can be temporarily stored in a container even when there is no place to place the excavated soil. It is also possible to return the excavated soil to its original position after completion of the specified work in the same way.In addition, only the surplus excavated soil in the case of burying a contreat product etc. in the excavated part is stored in a container and another There is an advantage that work efficiency in a narrow space or the like is remarkably improved, for example, it can be transported and discharged to a place.

In addition, since soil excavated by a bucket or other piled soil can be scooped and transported by the forward and backward movement of the fuselage, it is also useful as a relatively short distance soil transport device, and with the above-mentioned container attached Excavation work at a position close to the fuselage side by the bucket is not hindered by the presence of the notch-shaped recess at the tip of the container, and passing the bucket to this position has the effect of minimizing spillage to the surroundings. is there.

In addition, it is also possible to scoop the soil on the ground by the container itself, transport it to another place, and discharge it.
