Abstract

A tooth body is formed with a mounting part which is thicker than connection parts on both sides thereof, and the two adjacent connection parts are integrated and assembled through two gap reinforcement plates, and, as a result, the gap reinforcement plates finish a gap formed between two tooth bodies to prevent concrete mortar, sand or soil from spilling while reinforcing hardness, which can lead to long use. Moreover, as an outer edge of a tooth for flattening work is formed to be thick, the hardness of a part coming in contact with the ground during flattening work is reinforced to minimize the abrasion of the tooth, which can lead to long and economical use. Also, as a reinforcement protrusion is projected throughout the entire length on an outer edge of a connection part, the structural hardness of the tooth body can be reinforced while prevented from being easily worn out, which can lead to long use.

Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Prior to this, the terms or words used in the present specification and claims should not be construed as being limited to their ordinary or dictionary meanings, and the inventor may properly define the concept of the term in order to best describe his invention. It should be interpreted as meaning and concept consistent with the technical idea of the present invention in accordance with the principle that can be.

Accordingly, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiment of the present invention and do not represent all the technical spirit of the present invention, so various equivalents that can be substituted for them at the time of the present application It should be understood that there may be variations and examples.

In the tooth for split-type non-welding flat work of the excavator according to [Example 2] of the present invention, as shown in [Fig. The tooth body 100, and two gap reinforcing plates 200a and 200b that are fastened against each other between the two adjacent tooth bodies 100 are included.

In particular, the gap reinforcing plates 200a and 200b are mounted between two adjacent tooth bodies 100 so that the length can be adjusted as well as the length can be adjusted by being in close contact with each other in the form of a half-chin coupling, so that the width can be adjusted while moving in the width direction.

In addition, in the tooth body 100, the mounting portion 110 in the middle of the width assembled to the adapter A is formed thicker than the connecting portions 120 on both sides thereof to strengthen the rigidity of the mounting portion 110, By making the thickness of the connection part 120 and the thickness of the gap reinforcement plates 200a and 200b the same as or similar to that of the mounting part 110, the overall rigidity of the tooth for flat work according to the present invention can be evenly reinforced. did it

Hereinafter, such a configuration will be described in more detail with reference to the accompanying drawings. In the drawing, "A" is an adapter installed at predetermined intervals on the edge of the bucket.

go. Tooth body

The tooth body 100, as shown in [Fig. 1] and [Fig. 2], is mounted on the adapter (A) protrudingly mounted on the edge of the bucket, respectively. At this time, the tooth body 100 includes a mounting part 110 mounted on the adapter A, and a connection part 120 having the same size and shape on both sides based on the mounting part 110 as one body. .

1. Mounting part

The mounting portion 110 is formed in the center of the width of the tooth body 100, as in [Fig. 3] to [Fig. 5], and is formed to be thicker than the connection portion 120 to be described later. This is because, as the gap reinforcement plates 200a and 200b, which will be described later, are mounted on the connection part 120, the thickness of the mounting part 110 is the combined thickness of the connection part 120 and the reinforcement plates 200a, 200b. This is to achieve similar rigidity by making them the same or similar.

The mounting part 110 made in this way is configured to be integrally assembled by inserting the adapter (A) on one side and then assembling it through a pin, as shown in FIG. 3 . At this time, the adapter (A) has a jaw formed on the surface facing up and down so that it can be assembled in a predetermined direction when assembling. Of course, it does not matter if there is no such receiving groove.

2. Connection part

The connection part 120 is integrally configured to be symmetrical on the left and right with respect to the mounting part 110 , as in [ FIG. 3 ] and [ FIG. 4 ].

In particular, the connection part 120, as shown in [Fig. 5], as the tooth body 100 is mounted on the adapter (A), the adjacent connection part 120 is in close contact with the bucket, such as concrete mortar, sand or soil, etc. It is preferable not to leak concrete mortar, sand, or soil into the gap (G) of the adjacent connection part 120 when moving. However, due to various causes such as damage or deformation due to manufacturing errors or use of the tooth body 100 , a gap G is generated between the adjacent connection parts 120 . The gap G is closed through two gap reinforcing plates 200a and 200b to be described later that are installed to overlap the two adjacent connection parts 120 .

On the other hand, in the connection portion 120, as shown in [Fig. 3] to [Fig. 5], at least two fastening holes 121 are formed through each side on one side. The fastening hole 121 is a configuration for fastening and fixing the gap reinforcing plates 200a and 200b installed to overlap the adjacent mounting part 110 when the two tooth bodies 100 are installed side by side.

In a preferred embodiment of the present invention, the fastening hole 121, as shown in [Fig. 8], may be configured to overlap each other on both sides of each gap reinforcing plate 200a, 200b so that it can be fastened with a fastening bolt. . However, when the bucket capacity is large and it is not possible to sufficiently fasten with one fastening bolt, as shown in [Fig. Two gap reinforcing plates 200a, 200b to cover the damaged portion of the edge of the bucket together by mounting the gap reinforcing plate 200a to protrude above the tooth body 100 as shown in [Fig. 13]. Anyone skilled in the art to which the present invention pertains will readily understand that it can be used to adjust the overall length of the .

The tooth body 100 made in this way is fixed with a pin to each adapter (A) one by one as shown in [FIG. 1] and [FIG. 8], the gap reinforcing plates 200a and 200b are overlapped so that they are integrally fastened and fixed through the fastening hole 121.

me. gap reinforcement plate

The gap reinforcing plates 200a and 200b are composed of two pieces of the same size and shape, as shown in FIGS. 6 to 8 . At this time, these gap reinforcing plates 200a and 200b are formed to overlap between the two adjacent connecting parts 120 to fill the gap G formed between the connecting parts 120 .

The gap reinforcing plates 200a and 200b, as shown in [Fig. 6] to [Fig. 8], a half chin 210, and at least two rows of fastening slits 220 are formed.

1. half chin

The half chin 210 is a chin formed so that one of the gap reinforcing plates 200a, 200b can overlap with each other, as shown in FIG. The jaws 210 are made to face each other so that these gap reinforcement plates 200a and 200b are in the form of one plate. This is, as shown in [Fig. 8], this plate shape is formed with the same or slightly smaller width between the two adjacent connecting parts 120, so that the two gap reinforcing plates 200a and 200b are formed between the two connecting parts 120. By fixing it together, it is to prevent leakage of concrete mortar, sand, or soil between these gap reinforcing plates 200a and 200b.

2. Fastening slit

The fastening slit 220 is formed in at least two rows in pairs long in the width direction on each of the gap reinforcing plates 200a and 200b, as shown in FIGS. 6 and 8 . In this case, as the fastening slits 220 are formed in pairs, the fastening holes 121 respectively formed in the two connecting parts 120 adjacent to each fastening slit 220 are fastened, so that the gap reinforcing plates 200a and 200b are adjacent to each other. This is to close the gap G formed between the one or two connecting parts 120 . In addition, the reason for forming the fastening slit 220 in at least two rows is slightly different depending on a company manufacturing a tooth body or a model of an excavator. This is to allow the gap G to be neatly closed while adjusting the fastening position of the gap reinforcement plates 200a and 200b in the width direction.

These gap reinforcing plates (200a, 200b) can also be used in an angled form, but by chamfering or rounding both ends of the edge facing the half-tuck formed edge, the stress is not concentrated so that it can be used safely for a long time. It is preferable to do

The gap reinforcing plates 200a and 200b made as described above, as described above, have the same or similar rigidity as the thickness of the connection part 120 and the thickness of the mounting part 110 in either one. It is desirable to make it so that it does not lean toward the

Therefore, in the present invention, as the tooth body is mounted on each adapter, the gap reinforcing plate that can be adjusted in length and width is fastened to and fixed to the adjacent connecting part, thereby blocking the gap that may exist between the neighboring connecting parts and using a bucket of concrete. When transporting mortar, sand or soil, it is possible to prevent leakage through this gap.

The tooth for split-type non-welding flat work of the excavator according to [Embodiment 2] of the present invention has the same configuration as [Embodiment 1] described above, as in [Figs. 9] to [Fig. There is a difference in that a configuration for reinforcing the rigidity of the gap reinforcing plates 200a and 200b is added. Therefore, here, an additional configuration will be mainly described, and a detailed description of the configuration as in [Embodiment 1] will be omitted.

That is, in [Embodiment 2], as in [FIG. 9] to [FIG. 14], the end portion of the mounting portion 110, that is, on the opposite side to which the adapter (A) is coupled, a thick reinforcing protrusion 111 is formed to protrude. By doing so, it is possible to prevent wear or damage by reinforcing the rigidity of the part in contact with the ground or the like when flattening with a bucket.

In addition, in the connecting portion 120 formed on both sides of the mounting portion 110, as shown in [Fig. 10] and [Fig. 12], the outer edge of the surface where the gap reinforcement plate (200a, 200b) is not installed. Each of the reinforcing ribs 122 are formed to protrude, so that the rigidity of the connection part 120 can be reinforced.

On the other hand, in any one of the two gap reinforcing plates 200a and 200b installed in the connection part 120, [Fig. A reinforcing rib 230 is formed in parallel with the tooth body 100 so as to reinforce the rigidity of the outer edge of the tooth body 100 .

At this time, the front reinforcing protrusion 101 is formed on the edge in the direction opposite to the edge of the side where the tooth according to the present invention is inserted into the adapter, so that when the excavator works, wear or damage is the most It is designed to reinforce the rigidity of the part that is likely to occur first. In addition, the front reinforcing protrusion 101 may be configured to extend further along the edge of the connecting portion 120 by extending both ends, as shown in FIG. 18 .

The tooth for split-type non-weld flat work of the excavator according to [Example 5] of the present invention is the same as that of [Example 4] described above, as shown in [Fig. 19], but on the surface on which the front reinforcement protrusion 101 is formed There is a difference in that the slimming space 102 is formed. Therefore, detailed description of the same configuration as in [Embodiment 4] will be omitted here, and an additional configuration will be mainly described.

"과 같은 형태(흰색으로 표시된 부분이 살빼기 공간임)로 제작된 것을 예로 보여준다. 하지만, 이러한 살빼기 공간(102)은 투스의 강성이 떨어지지 않는 한 어떠한 형태로든지 제작할 수 있음을 본 발명이 속한 기술분야의 종사자라면 누구든지 쉽게 알 수 있을 것이다.[Embodiment 5], as shown in [Fig. 19], the front reinforcement protrusion 101 is formed on the surface to form a slimming space (102). Here, the slimming space 102 refers to a space in which the desired rigidity can be sufficiently obtained while reducing the weight by removing unnecessary parts without affecting the strength of the member. In this slimming space 102, in the figure, "

"It shows as an example that it is manufactured in the same form as (the part marked in white is the space for thinning out). However, this thin space 102 can be manufactured in any shape as long as the rigidity of the tooth does not decrease. Technical field to which the present invention belongs Anyone in the industry will be able to find out easily.

The tooth for split-type non-welding flat work of the excavator according to the sixth embodiment of the present invention has the same configuration as the above-described [Embodiment 4], as in [Figs. 20] to [Fig. 22], but the side reinforcement protrusions 103 ) by adding Therefore, here, the detailed description of the same configuration as in [Embodiment 4] will be omitted and only the additional configuration will be described.

[Embodiment 6], as shown in [Fig. 20] to [Fig. 22], side reinforcement protrusions 103 for the tooth body 100' installed on both edges among the adapters (A) mounted on the bucket are additionally is formed At this time, the side reinforcement protrusion 103 is formed on the edge portion exposed to the outside when the tooth body 100 ′ is mounted on the bucket, so that it can be easily worn on the ground or rocks embedded in the ground when flattening with a bucket. It is made to be used for a long time by reinforcing the rigidity of the part where it is located.

In addition, the side reinforcing protrusion 103 is formed to extend from the end of the front reinforcing protrusion 101, as shown in Figs. 20 and 21, this side reinforcing protrusion 103 is the front reinforcing protrusion 101 By making it thicker, it reinforces enough rigidity for the tooth body, which wears the most when flattening, so that it can be used for a long time.

As described above, the present invention can be used for a long time without being easily worn by adding a side reinforcement protrusion to the portion where the wear is most severe and appears quickly when flattening with a bucket.
