Description

[Detailed Description of the Invention] This invention relates to a bucket cart with a movable blade that is installed as a working attachment on a wheel loader or the like, and particularly relates to a bucket cart with a movable blade that is suitable for cargo handling work in a narrow space such as a ship's hold.

When the cargo in a ship's hold is bulk material such as ore, coal, powder, etc., most of the material is unloaded by the grab bucket of the unloader.

Eventually, the bulk material in the hold will gradually decrease, and even the remaining material in the hold, which has been reduced to near the bottom of the ship, will be brought ashore and collected in its so-called scattered state using only the grab bucket of the unloader. is not possible.

Therefore, when recovering the above-mentioned remaining material, a foil loader with a bucket is used, and the remaining material on the bottom of the ship is collected and piled up by the bucket operation, and the piled-up material is scooped up by the grab bucket of the unloader.

The work of recovering such residual materials also serves as cleaning inside the ship's hold, but generally, a plurality of reinforcing ribs extending vertically and horizontally are welded to the rising inner walls on both sides of the ship's hold.
Since a lot of bulk material remains between the ribs,
That material also needs to be recovered.

However, since the spacing between this type of ribs is generally narrower than the width of the opening of the well-known bucket bucket installed in the foil loader, it is impossible to collect the remaining material between the ribs using the bucket bucket. .

Therefore, in the past, the remaining material between the ribs has been scraped out manually by a scooping operation.

This type of scoping work requires a considerable amount of effort and time, and is inefficient.Especially in the summer, when the temperature inside a narrow ship's hold exceeds 40℃, scoping work inside the ship's hold is extremely difficult. It has become harsh.

This idea was made in view of the above circumstances, and its purpose is to enable cargo handling and other processing operations in narrow spaces where it is impossible to enter the bucket, such as between the ribs on the inside wall of a ship's hold.
Moreover, it is an object of the present invention to provide a bucket cart with a movable blade, which is configured to be able to selectively and smoothly carry out this work and normal bucket cart work at any time.

Another object of this invention is to provide a bucket cart with a movable blade that is simple in construction and highly versatile.

Hereinafter, preferred embodiments of this invention will be described based on the drawings.

The bucket cart shown in Fig. 1 is installed on a vehicle such as a wheel loader and used for cargo handling work in a hold. It is formed into a substantially V-shaped cross section with an upper plate 3 integrally connected to the rear end edge and extending diagonally upward at the front.

Further, the openings at both ends between the plates 2 and 3 are respectively closed by triangular side plates 4 and 5 that are integral with the opening edges.

Furthermore, a cutting edge 6 is attached to the front edge of the lower plate 2, and a spill plate 7 is attached to the open edge of the upper plate 3.

The bucket main body 1 having such a structure is provided with a movable blade 8 that can be rotated in the vertical direction between the upper and lower plates 2 and 3.

The blade 8 is mounted via a shaft 10 to a pair of left and right blade mounting brackets 9, 9' which are integrally protruded onto the lower plate 2 by welding or other means near the inner corner of the back side of the bucket main body 1. The end has a pivoted mounting configuration.

The blade 8 can be placed in a working position in which it extends forward along the lower plate 2 as shown by the two-dot chain line in FIG. It is designed to be selectively locked in one of the unused positions.

In the illustrated example, the locking means includes a pair of left and right bottom wall lock pin brackets 11A, 11B and a back wall lock pin bracket 12A, 12B on the inner wall surface of the bucket main body 1, respectively.

Bottom wall side lock pin bracket 11A, 11B
are located near the cutting edge 6 on the front end side of the lower plate 2, and the back wall side lock pin brackets 12A and 12B are located symmetrically with the bottom wall side lock pin bracket near the spill plate 7 of the upper plate 3, respectively. It is integrally protruded by means such as welding.

These lock pin brackets 11A, 11B
A lock pin 13 is selectively and removably inserted into the pin holes 12A and 12B.

The locking pin 13 has a head 13A at one end,
Moreover, the other end side has a snap pin hole 13B into which a retaining snap pin (not shown) can be freely inserted and removed.
(See Figure 2).

On the other hand, the blade 8 is provided with bracket fitting holes 14A, 14B for selectively fitting and aligning with the lock pin brackets 11A, 11B and 12A, 12B on the bottom and rear wall sides, respectively.

It is important that the blade 8 is formed narrower than the width of the opening of the bucket main body 1.

In the illustrated example, the blade 8 has a width set to approximately 1/3 of the width of the opening of the bucket main body 1, and extends outward from the opening end of the main body.

The bladed bucket bag constructed as described above is
It is used for work by being installed at the front of a vehicle such as a wheel loader via a lift arm, lift cylinder, tilt link lever, tilt cylinder, etc.

First, when performing normal bucket work,
The blade 8 is rotationally displaced to a non-use position along the upper plate 3 of the bucket main body 1 (the solid line position in FIG. 1). Then, the bracket fitting holes 14A, 14B of the blade 8 are inevitably fitted and aligned with the lock pin brackets 12A, 12B on the back wall side of the bucket main body 1, so the lock pin 10 is inserted into each pin hole of the bracket, and By inserting a snap pin into the snap pin hole 13B on the tip side of the lock pin, the blade 8 is locked and held in the above-mentioned non-use position.

In this state, the blade 8 does not interfere with the cutting edge 6 of the bucket main body 1 in any way, so that the loading work, etc., which is proper for the bucket can be carried out smoothly.

During the bucket work, when collecting materials remaining in a narrow place where it is impossible to enter the bucket, such as between the ribs on the inner side wall of a ship's hold, first remove the lock pin 13 and insert the blade 8 into the lower plate of the bucket main body. Rotate it upwards.

Also, the bracket fitting hole 14 of the blade 8
Insert the lock pin 13 into the pin hole of the lock pin bracket 11A, 11B on the bottom wall side that penetrates through A, 14B, and the snap pin hole 13 on the tip end side of the pin.
By inserting the snap pins in B, respectively, the blade 8 is locked in the operating position shown by the two-dot chain line in FIG.

In this state, the blade 8, which is narrower than the width of the opening of the bucket main body, extends in front of the cutting edge 6, so that the blade 8 scoops up or scrapes out the material in the narrow space. Processed materials can be collected smoothly.

It goes without saying that the blade 8 can have a removable mounting structure that allows it to be easily replaced at any time with one having a width appropriate to the conditions at the work site.

Further, as shown in FIG. 3, the blade 8 may have rising walls 15, 15' integrally formed on both side edges of the portion extending from the spill plate 7 of the bucket main body 1. In this case, since the tip side of the blade 8 has a groove-shaped cross section, it is effective for scooping up powder and granules in narrow spaces, and when locking the blade 8 in the above-mentioned non-use position, the raised walls 15, 15' There is no danger that it will get in the way.

Furthermore, the blade 8 may have a cutting at the tip, and in this case there is an advantage that simple excavation and earthwork work in a narrow space can be performed.

On the other hand, the bucket main body 1 may have a well-known configuration in which a main board is formed into a curved shape. In short, an existing bucket bag may be equipped with a blade as described above, and even in this case, the same effect can be obtained.

Further, the bucket main body 1 may be colored in an amount corresponding to the width of the blade 8 from the upper end of the back wall to the center of the back surface thereof. In this case, the operator can easily confirm the blade position from the driver's seat of the vehicle due to the colored portion, thereby improving bucket operability and workability.

As described above, this invention consists of a bucket main body and a vertically movable blade whose base end is pivotally supported within the main body, and the blade is formed narrower than the width of the opening of the bucket main body and extends outward. , and is configured to be selectively locked in either the used position along the bottom wall of the bucket main body or the unused position along the back wall, so that the following excellent effects can be achieved.

(i) By keeping the blade locked in the above-mentioned non-use position, loading work, etc. that is originally intended for the bucket can be carried out smoothly, and by keeping the blade locked in the above-mentioned use position, it can be used in narrow spaces where it is impossible to enter the bucket. Scooping and raking work can be carried out smoothly and efficiently. Therefore, there is a great advantage that one bucket can selectively perform the original function of the bucket and the blade function as appropriate depending on the situation at the work site.

(ii) Furthermore, since the bucket main body is formed with a substantially V-shaped cross section as described above, the blade can be joined parallel to the bottom wall surface or the back wall surface of the bucket main body in the used position or non-use position. ,
Therefore, there is no risk that the blade will bend under load.

(iii) Since the configuration is simple, it can be provided at low cost.
