Description

[Detailed description of the invention] This invention relates to a bucket structure suitable for processing work of iron ore, rocks, etc.

At bucket loading sites, lock buckets are generally used when handling iron ore, rocks, etc.

Lock bucket carts are made of higher quality materials, are thicker than standard work bucket carts, and have strong corner guards, making them highly durable.

However, even with such a rock bucket, for example, when unloaded rocks collide with the side plates of the bucket from the outside during rock loading, a severe uneven load acts on the side plates of the bucket. There is a risk that the life of the bucket will be shortened as it will damage the board.

In addition, in the case of a loader, there is a risk that the tires may be damaged by stepping on rocks left in front of the loader, leading to a reduction in tire life.

Therefore, it is necessary to move rocks and the like that have not been loaded onto the bucket to the outside of the traveling direction of the bucket side plates, tires, and suspension equipment.

However, in the past, for example, in Japanese Patent Application Laid-Open No. 57-24735, a shovel has been known in which stiff blade plates are provided on both sides of the shovel that extend outward and can be retracted.
These solid blades were used to compact the left and right side walls of the excavation hole, and the rock left outside beyond the width of the bucket could not be moved outward while being excavated.

In addition, although the excavation rig of Utility Model No. 52-83503 had a reinforcing member attached to the bucket, it was similarly impossible to move rocks, etc. to the outside.

This idea was made in view of the above circumstances,
The main purpose of this is to remove rocks, etc. remaining near the bucket to prevent rocks, etc. that have not been loaded in the bucket from hitting the side panels of the bucket or being trampled by the loader's tires or other undercarriage equipment. To provide a bucket structure capable of being splashed outward by using a cutting edge for a protector arranged along a side plate.

In order to achieve the above-mentioned problems, this invention (a) has a bucket bag structure in which side protectors projecting outward are provided on both sides of the bucket bag, and the side protectors have the following configuration.

(b) It has a protector main body which is fixed to the side panels of the bucket and consists of a box with a substantially triangular cross section that gradually expands outward from the front to the rear along the outer wall surface of the side panels of the bucket.

(c) A cutting edge for the protector is provided in the form of a plate, which is fixed along the sloped surface of the protector body and whose cutting edge is placed in contact with the outer wall surface of the side plate of the bucket. We are taking measures.

Therefore, rocks and the like that cannot be loaded in the bucket are excavated through the protector body through the vertical protector cutting edge, which is arranged wedge-shaped against the side plate of the bucket, and moved outward away from the bucket. This eliminates the possibility of colliding with the side plate of the bucket or being stepped on by the loader's tires or other undercarriage devices.

Preferred embodiments of the bucket structure of this invention will be described below with reference to the drawings.

First, the bucket cart 1 illustrated in FIG. 1 is a well-known lock bucket cart that is installed on a loader to load iron ore, rocks, etc., and side protectors 3 and 4 are provided on both side plates 1A and 1B of the bucket cart. It is integrated.

These side protectors 3, 4 have sharp front ends 3', 4' formed along the respective outer wall surfaces of the bucket side panels 1A, 1B, and a rear end 3'.
It has a wedge-shaped configuration that expands outward toward ', 4''.

More specifically, in the case of the side protectors 3 and 4 shown in FIG. 2, the protectors are made of a box having a substantially right triangular cross section and are welded to the outer wall surfaces of the bucket side panels 1A and 1B with the sloped portions facing outward. It consists of main bodies 3A, 4A, and protector cutting edges 3B, 4B which are removably fastened to the respective slope portions of the main bodies with bolts 5 and nuts 6.

In the case of the side protectors 3 and 4 illustrated in FIG. 3, the protector body 3 is different from that in FIG.
The only difference is that A and 4A are removably fastened to bucket side panels 1A and 1B with bolts 8 and nuts 9 via attachment reinforcing plates 7 that abut the respective inner wall surfaces of the side panels.

In the side protectors 3, 4 shown in FIGS. 2 and 3 above, the protector bodies 3A, 4A each integrally incorporate reinforcing aggregate 10, as shown in more detail in FIG. 4, and the rear end wall surfaces 3A', 4A' is provided with an opening 11 for tightening or unfastening the nuts 6, 9 of the bolts 5, 8.

Next, the operation of the above embodiment will be described with reference to FIG. 5. When loading rocks 12 using the bucket 1, the rocks 12 are not loaded into the bucket 1 but collide with the outside of the bucket side panels 1A and 1B. The rock 13 that is about to break is thrown off to the outside by rolling on the inclined surfaces of the cutting edges 3B, 4B of the side protectors 3, 4.

In this invention, the cutting edge may be integrally fixed to the protector body by welding or the like.

According to this invention, it is possible to prevent uneven loads on the bucket during loading work of rocks, etc., and to extend the life of the bucket.

In addition, during the above-mentioned loading operation, it is possible to prevent rocks, etc. that are not loaded into the bucket from being trampled by the tires of a loading machine such as a loader, or from entering the suspension equipment, thereby preventing damage to the suspension equipment. Preventable and beneficial.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) In a bucket tote structure in which side protectors projecting outward are provided on both sides of the bucket tote, the side protectors extend from the front to the rear along the outer wall surface of the side panels of the bucket tot. The main body of the protector consisted of a box with a generally triangular cross-section that gradually expanded outward and was fixed to both sides of the bucket. A bucket structure characterized by consisting of a plate-shaped cutting edge for a protector placed so as to be in contact with the outer wall surface of the side panel. (2) The bucket bag structure according to claim 1, wherein the protector body is comprised of a box having a substantially triangular cross section and is fixed to both sides of the bucket bag by welding or bolting. (3) The bucket structure according to claim 2, wherein the cutting edge for the protector is replaceably bolted to the sloped portion of the protector body.
