Description

Technical Field

[0001] The utility model relates to a bucket tooth seat of a mechanical bucket which can be used multiple times. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and load them into a transport vehicle or unload them to a stockpile yard. A detachable blade is provided on the edge of the bucket, and a row of bucket teeth is installed on the blade. The bucket teeth can enhance the cutting and digging capabilities of the bucket. The bucket teeth include a tooth seat fixed on the blade and a detachable tooth tip fixed on the tooth seat. The tooth tip is a wearing part. If the tooth tip fails due to severe wear, only the tooth tip needs to be replaced.

[0003] Currently, the gear holder is fixed to the blade in two main ways. One is to fix it to the blade by welding to obtain better strength, but it cannot be disassembled. The other is to fix it to the blade in a detachable manner with the help of screws, but the blade needs to be punched and tapped in the early stage. The fixing steps are relatively troublesome, and the screws are easy to loosen.

[0004] If the blade with a tooth holder welded to it cannot be used due to damage, it is necessary to replace it with a new one and remove the tooth holder fixed on the original blade for continued use. The simplest and most common way to disassemble is to cut it, but because the weld and the edge of the main structure of the tooth holder have been integrated, even very careful cutting will cause damage to the main structure of the tooth holder, which will in turn affect the structural strength of the tooth holder. If it continues to be used, it will affect the use effect of the bucket. Therefore, only a few of the removed tooth holders can be used again, and the material utilization rate is low. The tooth holders that cannot be used anymore can only be scrapped. Therefore, the material waste phenomenon is relatively serious and needs further improvement. Utility Model Content

[0005] In view of the current status of the above-mentioned prior art, the technical problem to be solved by the utility model is to provide a reusable mechanical bucket tooth seat which can ensure that the main structure is intact when cutting the tooth seat so that each cut tooth seat can be used multiple times while ensuring the use effect of the bucket, thereby greatly improving the material utilization rate and preventing waste.

[0006] The utility model solves the above technical problems by adopting the following technical solution: a mechanical bucket tooth seat that can be used multiple times, including a body, a positioning block for fixing the tooth tip is formed outwardly on the front side of the body, a clamping block is formed outwardly on the rear side of the body, a slot is opened between the left and right outer walls of the end of the clamping block, and the upper and lower inner walls of the slot are both horizontally arranged and parallel to each other, and the characteristics are:

[0007] The slot divides the clamp block into two clamp plates that are symmetrically arranged up and down, and a U-shaped extension block that is symmetrically arranged outward is formed on the rear side of each clamp plate and between the left and right outer walls;

[0008] The outer walls on opposite sides of the two U-shaped extension blocks are flush with the upper and lower inner walls of the slot respectively;

[0009] Each of the U-shaped extension blocks is provided with a plurality of U-shaped cutting grooves which are nested in sequence from the inside to the outside on the outer wall on the side opposite to the slot. Correspondingly, each of the U-shaped extension blocks is provided with the same number of U-shaped separation grooves which are nested in sequence from the inside to the outside on the outer wall on the side close to the slot. The position and direction of each of the U-shaped separation grooves cooperate with the position and direction of a corresponding U-shaped cutting groove.

[0010] Preferably, the vertical depth of each of the U-shaped cutting grooves at any point is no more than 5 mm.

[0011] Preferably, the vertical depth of each of the U-shaped separation grooves at any point is no more than 3 mm.

[0012] Preferably, the width of the U-shaped cutting groove is equal to the width of the U-shaped separation groove and is no greater than 3 mm.

[0013] Preferably, a triangular convex column for positioning is formed between the inner walls on the upper and lower sides of the bottom of the slot.

[0014] Compared with the prior art, the advantages of the utility model are: the utility model reserves a plurality of U-shaped cutting grooves for cutting the tooth seat, and when the blade of the cutting tool cuts the main body, the U-shaped cutting groove provides accurate guidance for the movement of the blade to ensure the accuracy of the cutting, thereby effectively avoiding accidental damage to the main structure to ensure that the remaining main structure after cutting is intact, so that each body cut from the original blade can be welded and fixed to the new blade again for continued use, while effectively maintaining its own structural strength to ensure the use effect of the bucket, thereby greatly improving material utilization to prevent waste.

[0021] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0022] like Figures 1-2 As shown, a mechanical bucket tooth holder that can be used multiple times includes a body 1, a positioning block 12 for fixing the tooth tip is formed outwardly on the front side of the body 1, a clamping block 11 is formed outwardly on the rear side of the body 1, and a slot 13 is opened between the left and right outer walls of the end of the clamping block 11, and the upper and lower inner walls of the slot 13 are both horizontally arranged and parallel to each other;

[0023] The slot 13 divides the clamping block 11 into two clamping plates 14 symmetrically arranged up and down, and a U-shaped extension block 15 symmetrically arranged outwardly is formed on the rear side and between the left and right outer walls of each clamping plate 14;

[0024] The outer walls of the two U-shaped extension blocks 15 on opposite sides are flush with the upper and lower inner walls of the slot 13 respectively;

[0025] A plurality of U-shaped cutting grooves 16 are provided on the outer wall on one side opposite to the slot 13 of each U-shaped extension block 15 and are nested in sequence from the inside to the outside. Correspondingly, a same number of U-shaped separation grooves 17 are provided on the outer wall on one side close to the slot 13 of each U-shaped extension block 15 and are nested in sequence from the inside to the outside. The position and direction of each U-shaped separation groove 17 cooperate with the position and direction of a corresponding U-shaped cutting groove 16.

[0026] The vertical depth of each U-shaped cutting groove 16 at any point is no greater than 5 mm.

[0027] The vertical depth of each U-shaped separation groove 17 at any point is no more than 3 mm.

[0028] The width of the U-shaped cutting groove 16 is equal to the width of the U-shaped separation groove 17 and is not greater than 3 mm.

[0029] A triangular convex column 18 for positioning is formed between the inner walls on the upper and lower sides of the bottom of the slot 13 .

[0030] A rounded edge 19 is formed at the corner of the end of the triangular protrusion 18 .

[0031] Processing method of matching blade:

[0032] According to the length of the blade 2 and the number of bucket teeth to be installed, a plurality of triangular notches 21 are opened on the outer wall edge of the blade 2 and are distributed in sequence and at equal intervals laterally. The left and right inner walls of the triangular notches 21 cooperate with the left and right outer walls of the triangular boss 18 on the body 1 respectively.

[0033] Installation method when using the main unit 1 for the first time:

[0034] The slot 13 of the body 1 is oriented toward the blade 2 and the blade 2 is inserted into the slot 13 laterally until the triangular protrusion 18 on the body 1 is inserted into one of the triangular notches 21 on the blade 2 to complete the accurate positioning of the blade 2 before welding; then, the side outer wall of each U-shaped extension block 15 and the upper and lower outer walls of the blade 2 can be welded with the help of welding equipment to form a U-shaped weld, and then the body 1 can be fixed on the blade 2 by welding. Figure 3 .

[0035] Disassembly method of body 1:

[0036] When the blade 2 is seriously damaged and cannot be used, the body 1 can be removed from the blade 2; when removing, the blade of the cutting tool is downward and perpendicular to the upper or lower inner wall of the slot 13, and then extends into the outermost U-shaped cutting groove 16 on each U-shaped extension block 15 and cuts along the direction of the U-shaped cutting groove 16 until the blade of the cutting tool extends into the U-shaped separation groove 17 corresponding to the above-mentioned U-shaped cutting groove 16. In this way, the body 1 can be removed by cutting and the part of the material welded on the damaged blade 2 can be discarded, but it effectively ensures that the main structure of the cut body 1 is intact and can continue to be used. Figure 4 .

[0037] Installation method when using the main unit 1 again:

[0038] Take a new blade plate 2, and then fix the cut body 1 on the new blade plate 2 by welding in the same way, so that the body 1 can continue to be used without using a new body 1, thereby achieving multiple uses.

[0039] Under the premise that the main structure of the body 1 can still be used, the number of U-shaped cutting grooves 16 determines the number of times the body 1 can be used continuously, until the innermost U-shaped cutting groove 16 is cut off, after which the body 1 can be used for the last time. Figure 5 .

[0040] The utility model reserves a plurality of U-shaped cutting grooves 16 for cutting the tooth seat. When the blade of the cutting tool cuts the main body 1, the U-shaped cutting groove 16 provides accurate guidance for the movement of the blade to ensure the accuracy of cutting, thereby effectively avoiding accidental damage to the main structure to ensure that the remaining main structure is intact after cutting. In this way, each main body 1 cut from the original blade can be welded and fixed to the new blade again for continued use. At the same time, the structural strength of the main body is effectively maintained to ensure the use effect of the bucket, thereby greatly improving the material utilization rate to prevent waste.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
