Description

Engineering machinery

Technical Field

The present utility model relates to a construction machine, and more particularly, to a construction machine to which a crusher can be attached.

Background

Work machines generally refer to all machines used in civil engineering or construction work. In general, a construction machine includes an engine and a hydraulic pump operated by power of the engine, and travels or drives various work devices using hydraulic oil discharged from the hydraulic pump. In addition, the construction machine may install various attachments (attachments) according to the kind of the job to be executed. For example, an excavator, which is one type of construction machine, is used by selectively attaching various accessories such as an excavating bucket (bucket), a breaker (breaker), a vibrator, and a hammer to one end of an arm. Among them, crushers are installed on construction machinery and are widely used in various departments such as mining, smelting, building materials, highways, railways, maintenance and chemical industries.

However, the conventional crusher is directly fastened to the arm and the connecting rod of the construction machine. That is, the crusher crushes the crushed material by repulsive force generated during crushing acting on the arm of the construction machine. Therefore, if the overturning load of the construction machine and the force of the driving cylinder are not sufficiently larger than the repulsive force generated when the crusher performs the impact work, there is a problem in that the impact force of the crusher is transmitted to the construction machine, not to the crushed material, and the work cannot be performed as intended.

Further, there is a problem in that the weight required to withstand the repulsive force of the construction machine varies depending on the type and specification of the crusher mounted on the construction machine.

Furthermore, references to expressions such as "comprising", "having", etc. used in this specification are to be understood as covering open-ended terms that may include the possibility of other embodiments unless otherwise noted in the words or sentences containing the expressions.

Furthermore, the singular forms recited in the specification may include plural forms unless otherwise indicated, and the same applies to the singular forms recited in the claims.

The terms "first", "second", and the like used in the present specification are used to distinguish a plurality of constituent elements from one another, and do not limit the order or importance of the constituent elements.

Next, a construction machine 101 according to an embodiment of the present utility model will be described with reference to fig. 1 to 3.

For example, the work machine 101 may be an excavator (excavator). In addition, a plurality of accessories (accessories) including a bucket (pocket), a tilt rotator (shovel), a breaker (breaker), a vibrator, a hammer, and the like may be selectively mounted to the construction machine 101 as necessary.

In the first embodiment of the present utility model, a construction machine 101 to which a crusher 300 of a plurality of accessories is attached will be described.

As shown in fig. 1, the construction machine 101 includes a boom 200, a crusher 300, a weight adjuster 500, a first connecting rod 410, and a second connecting rod 420.

The arm 200 can perform a rotation operation with one side as a rotation center. For example, arm 200 may be driven by operating a drive cylinder (not shown) with hydraulic oil supplied from a hydraulic pump (not shown).

The crusher 300 comprises a chisel 310 that strikes the crushed material. In addition, the crusher 300 may be coupled to a weight adjuster 500 to be described later. For example, the crusher 300 may crush a crushed material by using a hydraulic force of a cylinder to raise and lower a piston to strike a striking force of a chisel 310 as a crushing tool. That is, when the piston reciprocates by the hydraulic pressure of the cylinder, the chisel 310 is hit, and the object to be crushed is crushed by applying a strong impact.

Further, the crusher 300 may include a first fastening hole 351 for connecting with a first connection hole 551 of a weight adjuster 500 to be described later, and a second fastening hole 352 for connecting with the other end of the first connection rod 410 to be described later.

The weight adjuster 500 may be rotatably coupled to the other side of the stick 200 and rotatably coupled to a region of the crusher 300. That is, the weight adjuster 500 is provided between the other side of the stick 200 and the crusher 300 to support the crusher 300.

As shown in fig. 2 and 3, the weight adjuster 500 may include: a first connection hole 551 for coupling with a region of the crusher 300, a second connection hole 552 for connecting with one end of a first connection rod 410 to be described later, a third connection hole 553 for rotatably coupling with the other side of the stick 200, and a fourth connection hole 554 for connecting with one end of a second connection rod 420.

The first and third connection holes 551 and 553 may be formed at one side end of the weight adjuster 500. At this time, the first connection hole 551 may be formed in a region adjacent to the crusher 300 in one side end, and the third connection hole 553 may be formed in a region adjacent to the arm 200 in one side end.

The second connection hole 552 may be formed at the other side end opposite to one side of the weight adjuster 500. At this time, the second connection hole 552 may be formed in a region adjacent to the crusher 300 in the other side end portion.

The fourth connection hole 554 may be formed between one side end and the other side end of the weight adjuster 500.

Further, the weight adjuster 500 may include a pair of side wall parts 550 spaced apart from each other, and a connection part 560 interposed between the pair of side wall parts 550. The first, second, third, and fourth connection holes 551, 552, 553, 554 may be formed through the pair of side wall portions 550.

In addition, the weight adjuster 500 may adjust the weight according to the size and weight of the connection part 560. When the tilting load of the working machine 101 required to stably strike the crushed material by the crusher 300 mounted on the working machine 101 is insufficient, the insufficient tilting load of the working machine 101 can be compensated for by adjusting the weight of the weight adjuster 500. A wide variety of crushers 300 may be installed in the work machine 101, although the required tipping load of the work machine 101 may be different for each crusher 300, according to an embodiment of the utility model, the required load may be easily adjusted to be applied to the crusher 300 by the weight adjuster 500.

One end of the first connecting rod 410 may be rotatably connected with the weight adjuster 500, and the other end may be rotatably connected with another region of the crusher 300. At this time, at least one of both end portions of the first connecting rod 410 may be detachably coupled to the weight adjuster 500 or the crusher 300 by the coupling pin 700. That is, the coupling pin 700 is removed, and the first connecting rod 410 may be separated.

One end of the second connection lever 420 may be rotatably connected with the weight adjuster 500, and the other end may be directly or indirectly connected with the stick 200. For example, the other end of the second connecting rod 420 may be directly connected to the stick 200, or the other end of the second connecting rod 420 may be connected to the stick 200 by a wire or cable. At this time, at least one of both end portions of the second connection lever 420 may be detachably coupled to the weight adjuster 500 or the stick 200 by the coupling pin 700. That is, the second connecting rod 420 can be separated by removing the coupling pin 700.

Further, as shown in fig. 4, even if the crusher 300 and the arm 200 are connected by the weight adjuster 500, the construction machine 101 according to an embodiment of the present utility model can freely operate.

Further, in the construction machine according to an embodiment of the present utility model, the crusher 300 may be one selected from a plurality of crushers 300 having different distances between the first fastening hole 351 and the second fastening hole 352 from each other.

The distance L1 between the first fastening hole 351 and the second fastening hole 352 of the crusher 300 shown in fig. 5 may be smaller than the distance L2 between the first fastening hole 351 and the second fastening hole 352 of the crusher 300 shown in fig. 6. That is, the crusher 300 shown in fig. 6 may be relatively larger in size.

However, according to an embodiment of the present utility model, by using the second connection rod 420, it is possible to connect all the crushers 300 having different sizes and specifications from each other using the same weight adjuster 500 without replacing the weight adjuster 500.

With this configuration, the construction machine 101 of an embodiment of the present utility model can not only selectively install a wide variety of crushers 300 as needed, but also effectively cancel out repulsive force generated when performing work.

Although the embodiments of the present utility model have been described above with reference to the accompanying drawings, it will be understood by those skilled in the art that the present utility model may be embodied in other specific forms without changing the technical spirit or essential features of the present utility model.

The above-described embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing detailed description, and all changes and modifications which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
