Abstract

The present invention relates to a flattening apparatus for an excavator. When flattening the ground surface, the conventional technology mounts a flattening work plate with a flat plate-shaped bottom engaged with a tooth engaged with an end of a bucket to scratch or press the upper soil on the ground surface. However, there have been difficulties in engaging and disassembling processes and the functions have been insufficient. To solve such problems, the flattening apparatus for an excavator of the present invention has been developed to be used without a bucket, and to be mounted on ends of arms of the excavator and flatten the ground surface by leveling and pressing the ground surface into a flat surface by the flat surface on a bottom surface of the apparatus. The flattening apparatus comprises: an arm connection unit having two lateral fixing shafts to be engaged with ends of arms of an excavator; and a main body including a pair of forward-backward frames extended parallelly forward and backward, two or more lateral frames having both ends connected to and fixed on the forward-backward frames and an upper center with the arm connection unit mounted thereon, and a rotation roller having both ends rotatably fixed on a front side of the forward-backward frame.

Description

The flatness work apparatus for excavator}

The present invention relates to a leveling device for an excavator. To be described in more detail, when performing the work of leveling the ground, conventionally, a flattening plate with a flat bottom connected to the tooth attached to the end of the bucket is installed to level the topsoil of the ground. This is about a flattening device for an excavator that was developed to allow the bucket to be removed and installed to solve the problems of scraping or pressing, but having difficulties in the assembly and disassembly process and not being functional enough.

An excavator is also called an excavator or excavator. The boom, arm, and bucket are sequentially rotatably mounted on the traveling body, and each hydraulic cylinder allows various movements, allowing the bucket to dig or cut the ground and scoop up soil. It is mainly used.

Excavators can be used by replacing buckets of various sizes depending on the task, and by replacing work equipment such as breakers for crushing hard ground or rocks, and crushers for dismantling and crushing buildings, a wider variety of work is possible. .

On the other hand, when performing excavation and soil transportation, which are the main purposes of excavators, it is necessary to clean the ground evenly after performing the work, and at this time, the back of the bucket is used to push and press evenly and compact it.

However, when using existing buckets in this so-called leveling work, the area of the plane where the ground can be compacted is limited, so the work takes a lot of time. To solve this problem, a tee (teeth) mounted on the bucket to assist the excavation work is used. It is used by being equipped with a flat work board with a flat bottom that allows the teeth or teeth to be inserted and fixed.

However, in the case of such a flat work board, since it is attached to the teeth mounted on the bucket, a lot of force is applied when pressing the ground, so there is a risk of damage from excessive force, and if it is damaged, a lot of time is consumed in the process of replacing it. Problems arise in which work efficiency decreases.

In addition, the process of mounting a leveling work board has the disadvantage of being inconvenient as it requires a considerable amount of time and usually more than two people to secure it firmly. In addition, with the leveling work board installed in this way, the leveling work must be done to ensure that the ground is even and uniform. The process of unfolding and pressing required considerable skill on the part of the worker.

Accordingly, the configuration of the present invention will be described in detail with the accompanying drawings so that those skilled in the art can easily understand and reproduce it.

Figure 1 is a perspective view according to an embodiment of the present invention, and Figure 2 is a state diagram of use according to an embodiment of the present invention, which is mounted on the end of the arm 21 of the excavator 2 and flattens the ground by the plane of the bottom. In the leveling device (1) of an excavator, which performs leveling work by leveling and pressurizing;

The flattening device (1) includes an arm connection portion (11) having two fixed shafts (111) in the left and right directions to engage the end of the arm (21) of the excavator (2);

A pair of front-to-back frames 121 extending in parallel in the front-to-back direction, and two or more left and right frames whose both ends are connected and fixed to the front-to-back frames 121 and the arm connection portion 11 is mounted at the upper center. (122) and a main body 12 having rotary rollers 123, both ends of which are rotatably fixed in front of the front and rear frame 121 (1). ) is shown.

This institute was designed to solve the problem of installing a flat-type device in addition to the bucket that was previously mounted on the excavator (2), which made it difficult to combine and separate and could not guarantee durability against large external forces. The bucket itself was separated and a flattening device ( Mounting 1) can be performed by operating the arm 21, making the work easier.

In addition, in the case of the bucket, since it is used for excavation, the basic shape and weight that are unrelated to flattening occupy a large amount, so the area that can be worked at once is limited. However, the flattening device (1) of this hospital is limited to the area of the main body (12). It has a floor area that is more than twice that of the bucket, improving work efficiency, and in particular, the rotating roller 123 can play a role in leveling the ground.

In addition, the present application additionally presented an embodiment in which the main body 12 is provided with one or more reinforcing frames 124 connecting a pair of left and right frames 122 located at the rear.

In the above embodiment, a reinforcement frame 124 is additionally formed for the purpose of reinforcing the main body 12. In particular, as shown, the part where the arm connection part 11 is mounted is reinforced and the arm connection part 11 is more rigid. This is an embodiment to ensure that it can be firmly fixed.

This arm connection portion 11 is vertically installed from the upper part of the main body 12, extends in the front and rear directions, and is formed by a pair of connecting ribs 112 on which fixing shafts 111 are mounted at the front and rear, respectively. .

Figure 3 is a perspective view according to another embodiment of the present invention, in which a flat plate 125 is welded and fixed to the bottom of the main body 124, and is mounted on a close contact portion between the left and right frame 122 and the flat plate 125. An embodiment was presented characterized in that it is additionally provided with a plurality of triangular-shaped reinforcement panels 126.

In the above embodiment, a flat plate 125 is installed to secure a surface that can press the ground, and a reinforcement panel 126 to reinforce the flat plate 125 is additionally installed to protect the flat plate 125 from pressure or impact during the flattening operation. ) is an embodiment that prevents deformation.

Figure 4 is a perspective view according to another embodiment of the present invention, wherein the main body 124 has a pair of shaft mounting portions 131 spaced apart in the front and rear directions and protruding upward on the upper surface of the main body 124, and the shaft mounting portion 131. A tilting shaft 132 that is fixed through, a tilting bracket 133 whose lower part is rotatably connected surrounding the tilting shaft 132, the upper part is flat and has an arm connection portion 11 formed thereon, and both ends Characterized by an additional tilting operation unit 13 including a tilting cylinder 134 rotatably connected to the connection rib 112 of the arm connection unit 11 and the upper surface of the main body 12. An example is shown.

In general, flattening work can be done by forming a slope on a slope, and in this case, the excavator aligns the traveling body in the direction of the slope and performs the work by making a back-and-forth reciprocating motion.

However, if there is not enough space for the traveling body to reciprocate, the work is difficult. In the above embodiment, the traveling body enters perpendicular to the inclined direction and the angle of the main body 12 is adjusted by the tilting cylinder 134 to operate on a slope. This is an embodiment that makes work possible.
