Description

[Detailed description of the invention] This invention is a civil engineering vehicle that is constructed by supporting a boom equipped with a bucket at the tip on the top surface of a swivel table that is rotatably mounted on the vehicle body so that it can be rotated up and down. Regarding earth and sand removal equipment.

More specifically, the civil engineering vehicle targeted in the present invention has crawlers 10, 10 installed on the left and right sides, as shown in FIGS. 1 and 2.
The swing support mechanism 1
A swivel base 2 is rotatably mounted on the swivel base 2 via the swivel base 1, and on the upper surface of the swivel base 2, the base end of a boom 32 connected to the upper end is connected to an arm 31 supporting a bucket 30. A mounting plate 20 fixed to the
This is a civil engineering vehicle called a backhoe, which is supported on a support shaft 20 so as to be rotatable up and down about a support shaft a, and is equipped with a driver's seat 21, an engine E, a hydraulic oil tank T, etc.

The civil engineering vehicle A configured in this manner may be used in civil engineering work to dump earth and sand scooped up by the bucket 30 into the loading platform of a dump truck located behind the vehicle body 1 of the civil engineering vehicle A. . This work involves lifting and rotating the boom 32 and rotating the arm 31 and bucket 30 to scoop up dirt from the work site in front of the vehicle body 1 into the bucket 30, and then rotate the swivel platform 2 180 degrees to raise the boom. 32 faces toward the rear of the vehicle body 1, and in that state, rotate the boom 32 and others again to move the bucket 3 toward the rear of the vehicle body 1.
This is done in the process of discharging the earth and sand in the dump truck onto the loading platform of the dump truck, but when turning the turning platform 2,
In order to minimize the rotation locus of the boom 32 that is scooping up dirt into the bucket 30 at the tip, the upper end of the boom 32 that pivotally supports the arm 31 is fixed as shown in FIG. The boom 32 and the bucket 3 are pulled up to a position substantially above the support shaft a at the base end of the boom 32.
0 and the arm 31 are positioned above the swivel base 2.

For this reason, bucket 30, which is scooping up soil and sand,
However, every time the swivel base 2 is rotated, the bucket 3
The earth and sand spilling from 0 falls onto the upper surface of the engine cover 4 that covers the engine E mounted on the swivel base 2, and this earth and sand gradually accumulates, thereby expanding the range of rising and rotation of the boom 32 to the rear. To, the third
As shown in the figure, the water flows into the notch-shaped recess 5 formed at the rear of the support shaft a of the boom 32 on the upper surface side of the engine cover 4, and the boom 32 is raised and rotated. When the boom 32 is rotated, the boom 3
A problem has arisen that impedes the standing and turning of the patient.

For this reason, work is often performed to sweep off the dirt that has fallen onto the top surface of the engine cover 4 before it accumulates in large quantities. Since it is located in the center of the swivel base 2 away from the outer periphery of the swivel base 2, when sweeping the earth and sand off the top surface of the engine cover 4 from the outer periphery of the swivel base 2, In many cases, dirt is pushed into the recess 5 instead, so cleaning work on the top surface of the engine cover 4 is carried out to prevent the dirt that has fallen onto the top surface of the engine cover 4 from flowing into the recess 5. There are problems that make this extremely troublesome.

The present invention has been developed to solve these problems, and allows the work of sweeping off the dirt that has fallen onto the top surface of the engine cover 4 to be done quickly and without causing the dirt to flow into the recess 5. The purpose is to provide new means to easily carry out this process.

To this end, in the present invention, in the above-mentioned civil engineering vehicle, a mat made of a flexible material such as rubber is laid on the top surface of the engine cover that covers the engine mounted on the swivel base, so that it can be moved in and out. , the peripheral edge of the mat located on the outer peripheral side of the swivel base is rotatably connected to the peripheral edge of the engine cover, and the side of the periphery of the pine near the center of the swivel base is formed as a free end. This is a vehicle for civil engineering.

Next, embodiments will be described in detail with reference to the drawings. Note that the same reference numerals in the drawings as in the conventional means are used for constituent members having the same effect.

In FIGS. 4 and 6, 2 is rotatably mounted on the upper surface of the vehicle body 1, which is driven by left and right crawlers 10, 10, via a swing support mechanism 11. A swivel base 32 is fixedly mounted on the swivel base 2. Mounting plate 20, 2
A boom whose base end is pivotally supported on a support shaft a provided at 0, 31
21 is an arm that is connected to the upper end of the boom 32 so as to be able to bend and rotate; 30 is a bucket that is pivoted and connected to the tip of the arm 31; 21 is a seat provided on the side of the boom 32 on the upper surface of the swivel base 2; 22 is a roof covering above the seat 21; 23 is the roof 22;
24 is a cover disposed on the other front end side of the boom 32 and covering a hydraulic oil tank T (not clearly shown in the drawing) provided on the swivel base 2;
is an engine cover that covers the engine E (not clearly shown in the drawing), which is arranged to extend from the rear of the cover 24 to the rear of the boom 32, and these are different from the previous civil engineering vehicle A. do not have. On the upper surface side of the engine cover 4, a notch-shaped recess 5 is provided in a portion located behind the base end 32a of the boom 32 described above, for expanding the range of rising and rotation of the boom 32 to the rear. It is shaped.

M is a mat laid on the upper surface of the engine cover 4 so as to be freely releasable and detachable, and is made of a flexible material such as rubber so as to be freely bendable. The mat M is formed to be somewhat wider than the upper surface of the engine cover 4, and a notch 60 is formed in a portion corresponding to the recessed portion 5 described above. And the Matsutto M
is a part of the peripheral edge of the engine cover 4, which is located on the outer peripheral side of the above-mentioned swivel base 2;
1, and a grip H is mounted on the upper surface of the mat M at a position near the aforementioned recess 5 which is close to the center of the swivel base 2. .

The embodiment device constructed in this manner operates as follows.

At the work site, the arm 31 is folded and the boom 32 is erected in order to scoop earth and sand into a bucket 30 attached to the tip side of the boom 32 and position the bucket 30 behind the body of the civil engineering vehicle A. When the swivel base 2 is rotated, spillage from the bucket 30 may cause damage to the engine cover 4.
The earth and sand falling on the upper surface is deposited on the upper surface of the mat M placed on the upper surface of the engine cover 4.

Then, using the grip part H provided on the mat M, pull the mat M toward the outer circumference of the swivel base 2, and pull it out sequentially from the side closest to the recess 5 as shown by the chain line in FIG. By peeling it off,
The pine M moves the pine away from the recess 5, and further moves the pine M as shown by the chain line in FIG.
By rotating the engine cover 4 so as to tilt it down from the top surface toward the outer periphery of the fuselage, the engine cover 4 can be brushed off to the outer periphery of the warped fuselage.

As explained above, in the civil engineering vehicle according to the present invention, spills from the bucket 30 cause damage to the engine cover 4.
The work to remove the dirt and sand that has accumulated on the top of the engine cover 4 is done by sequentially peeling off the mat M made of a flexible material spread on the top surface of the engine cover 4, starting from the side closest to the depression 5. Since this can be done by discharging the dirt from the engine cover 4 while moving it in the direction away from the boom 32, it is extremely easy to remove the dirt on the engine cover 4 that flows into the depression 5 and becomes a hindrance to the upright rotation of the boom 32. By operation, it becomes possible to cleanly remove it while preventing it from flowing into the recessed part 5.
