Description

Construction machine

Technical Field

The present invention relates to an engineering machine, and more particularly, to an engineering machine to which a crusher can be attached.

Background

A working machine generally refers to all machines used in civil engineering or construction work. In general, a construction machine includes an engine and a hydraulic pump that is operated by power of the engine, and travels or drives various working devices by hydraulic oil discharged from the hydraulic pump. In addition, the construction machine is provided with various attachment devices (attachments) according to the type of work to be performed. For example, an excavator, which is a type of construction machine, is used by selectively attaching various attachments such as an excavating bucket (bucket), a crusher (breaker), a vibrator, and a hammer to one end of a boom. Among them, crushers are mounted on construction machines to be widely used in such as sectors as mines, smelting, building materials, roads, railways, repairs, chemical industries.

However, the conventional crusher is directly fastened to the arm and the connecting rod of the construction machine. That is, in the crusher, a repulsive force generated at the time of crushing acts on an arm of the construction machine to break the object to be crushed. Therefore, if the tipping load of the construction machine and the force of the drive cylinder are not sufficiently larger than the repulsive force generated when the crusher performs the striking work, the striking force of the crusher cannot be transmitted to the object to be crushed and transmitted to the construction machine, and the work cannot be performed as desired.

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

Detailed Description

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that those skilled in the art to which the present invention pertains can easily carry out the embodiments. The present invention may be embodied in many different forms and is not limited to the embodiments described herein.

In addition, in the embodiments, the same reference numerals are used for the constituent elements having the same configuration and the description is representatively made in the first embodiment, and only the configuration different from the first embodiment is described in the remaining second embodiment.

The figures are schematic and not drawn to scale. Relative dimensions and proportions of parts shown in the figures have been shown exaggerated or reduced in size, for the sake of clarity and convenience in the drawings, and any dimensions are exemplary only and not limiting. In addition, the same reference numerals are used for the same structures, elements or components shown in two or more figures to represent similar features.

Embodiments of the present invention specifically show desirable embodiments of the present invention. As a result, various variations of the illustration are envisioned. Thus, embodiments are not limited to the particular manner in which the regions are shown, and include variations from the manner in which the regions are manufactured, for example.

Next, a construction machine 101 according to a first embodiment of the present invention will be described with reference to fig. 1 to 4.

For example, the work machine 101 may be an excavator (excavator). In addition, in the working machine 101, a plurality of attachment (attachment) devices including a bucket (bucket), a tilt rotator (tilt rotator), a shovel (cover), a breaker (breaker), a vibrator, a hammer, and the like may be selectively installed as needed.

In the first embodiment of the present invention, the construction machine 101 in which the crusher 300 is mounted among the plurality of attachment devices will be described.

As shown in fig. 1, the working machine 101 includes a stick 200, a weight adjuster 500, a connecting rod 400, and a crusher 300.

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

One end of the connection rod 400 may be rotatably connected to a weight adjuster 500 to be described later, and the other end may be directly or indirectly connected to the arm 200. For example, the other end of the connecting stick 400 may be directly connected to the stick 200, or the other end of the connecting stick 400 may be connected to the stick via a wire or cable.

The crusher 300 is coupled to a weight adjuster 500 to be described later, and may include a chisel 310 striking a crushed object. For example, the crusher 300 may crush the crushed object by striking force of a chisel 310 as a crushing tool by raising and lowering a piston using hydraulic pressure of a cylinder. That is, the piston reciprocates by the hydraulic pressure of the cylinder to strike the chisel 310, and a strong impact is applied to the object to be crushed to crush the object.

The weight adjuster 500 is rotatably coupled to the other side of the stick 200. In addition, the weight adjuster 500 is combined with the crusher 300 to support it. That is, the weight adjuster 500 may be disposed between the other side of the stick 200 and the crusher 300.

As shown in fig. 2, the weight adjuster 500 may include: an adjuster body 550 having a first coupling portion 552 coupled to the arm 200 and the connecting rod 400, and a second coupling portion 553 coupled to the crusher 300; and one or more weight plates 580 coupled to an area of the adjuster body 550.

Specifically, a first coupling portion 552 coupled to the arm 200 and the connecting rod 400 is formed at one side surface of the adjuster body 550, a second coupling portion 553 coupled to the crusher 300 is formed at a lower surface of the adjuster body 550, and a weight plate 580 is provided at an upper surface of the adjuster body 550.

In addition, the weight adjuster 500 may adjust the weight applied to the crusher 300 in the kind and number of the weight plates 580 coupled to the adjuster body 550. That is, when the required tipping load of the construction machine 101 is insufficient for the crusher 300 mounted on the construction machine 101 to stably strike a crushed object, the insufficient tipping load of the construction machine 101 can be compensated for by adjusting the type and number of the weight plates 580 mounted on the weight adjuster 500.

A wide variety of crushers 300 may be installed in the working machine 101, and although the required tilting load of the working machine 101 per crusher 300 is different, according to the first embodiment of the present invention, it is easily adjusted to apply a required load to the crusher 300 by the weight adjuster 500.

At this time, the weight plate 580 may be located on an extension of a length direction of the chisel 310 of the crusher 300.

In addition, the weight adjuster 500 may further include a coupling bolt 570. In addition, one or more through holes for bonding may be formed in the weight plate 580. The coupling bolt 570 may be coupled to the adjuster body 550 by passing through a coupling through hole of the weight plate 580, thereby attaching the weight plate 580 to the adjuster body 550.

Further, as shown in fig. 3, the weight center COG1 of the weight adjuster 500 may be located on an extension of the length direction of the chisel 310 of the crusher 300. Thus, the striking force of the crusher 300 can be efficiently transmitted to the object to be crushed.

Further, as shown in fig. 4, the weight center COG2 in a state where the weight adjuster 500 and the crusher 300 are coupled may be located relatively close to a rotation center between the arm 200 and the weight adjuster 500 compared to a side of the crusher 300 farthest from the rotation center between the arm 200 and the weight adjuster 500. As such, the weight center COG2 of the weight adjuster 500 and the crusher 300 is located near the rotation center of the arm 200, so that the user can easily operate the arm 200 and the crusher 300.

With this configuration, the construction machine 101 according to the first embodiment of the present invention can effectively cancel the repulsive force generated when the plural types of crushers are operated.

Next, a construction machine 102 according to a second embodiment of the present invention will be described with reference to fig. 5.

As shown in fig. 5, the construction machine 102 according to the second embodiment of the present disclosure may further include an elastic member 800.

The elastic member 800 may be provided between the crusher 300 and the weight adjuster 500 on an extension of the length direction of the chisel 310 of the crusher 300.

Such an elastic member 800 is located on an extension of the chisel 310 of the crusher 300 in the longitudinal direction to buffer the impact force transmitted to the crusher 300 of the working machine 102, so that the entire durability of the working machine 102 can be increased.

In addition, the elastic member 800 may be formed in various forms such as a coil spring or a plate spring.

With this configuration, the construction machine 102 according to the second embodiment of the present invention can not only effectively cancel the repulsive force generated when the plurality of types of crushers operate, but also alleviate the impact force transmitted to the construction machine 102 to increase the durability of the construction machine 102, and reduce the fatigue feeling experienced by the user.

Although the embodiments of the present invention have been described above with reference to the drawings, those skilled in the art to which the present invention pertains will appreciate that the present invention can be implemented in other specific ways without changing the technical ideas or essential features of the present invention.

Therefore, the above-described embodiments should be construed as illustrative and not restrictive in all respects, the scope of the present invention being indicated by the appended claims, and all changes or modifications derived from the meaning and range of the claims and their equivalents should be construed as falling within the scope of the present invention.
