Description

Technical Field

[0001] The utility model relates to an excavator blade which is convenient for disassembling a bucket tooth seat. Background Art

[0002] The bucket on the excavator is an important component used for digging and loading materials. A detachable blade is set at the bottom edge of the opening of the bucket, and a row of bucket teeth is installed on the blade to enhance the cutting and digging capabilities of the bucket.

[0003] The bucket tooth consists of a tooth seat and a tooth tip. The tooth seat is fixed on the blade, and the tooth tip is detachably fixed on the tooth seat for easy replacement. If the tooth tip fails due to severe wear, only the tooth tip needs to be replaced.

[0004] The tooth holder fixed on the blade by welding has good strength and connection firmness, but it is inconvenient to disassemble the tooth holder. If the tooth holder cannot be used due to severe damage, it is necessary to remove the damaged tooth holder and replace it with a new one. The simplest and most common way to disassemble the tooth holder is cutting. However, since the tooth holder and the blade are directly welded and fixed and fit tightly, even if you are very careful, you cannot avoid damage to the blade of the cutting equipment to the blade, which will affect the structural strength of the blade and shorten its service life. In severe cases, it will directly cause the blade to be scrapped. In order to minimize the damage to the blade, the cutting speed can only be slowed down, which leads to a slow replacement efficiency of the tooth holder, which needs further improvement.

[0023] 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.

[0024] like Figures 1 to 4 As shown, an excavator blade for easily disassembling a bucket tooth seat comprises a body 1 for fixing a bucket tooth seat 4, and also comprises a plurality of U-shaped connection block assemblies arranged on the body 1 and distributed laterally and evenly spaced from left to right, wherein the U-shaped connection block assembly comprises two U-shaped connection blocks 2 which are symmetrically fixed on the upper and lower outer walls of the body 1 and can be disassembled respectively;

[0025] The U-shaped outer wall of the U-shaped connecting block 2 is provided with a plurality of U-shaped guide grooves 21 which are sequentially distributed from top to bottom. Correspondingly, the U-shaped inner wall of the U-shaped connecting block 2 is provided with the same number of U-shaped spacing grooves 22 which are sequentially distributed from top to bottom.

[0026] Each U-shaped guide groove 21 is arranged at the same height as a corresponding U-shaped spacing groove 22;

[0027] A plurality of countersunk holes 23 arranged in a U-shape are also provided on the outer wall of the U-shaped connecting block 2 on the side opposite to the main body 1. Correspondingly, the same number of threaded through holes 11 arranged in a U-shape are provided between the upper and lower outer walls of the main body 1.

[0028] A through hole 24 is provided between the bottom center of each countersunk hole 23 and the outer wall of one side of the U-shaped connecting block 2 that is attached to the body 1, and each through hole 24 cooperates with a corresponding threaded through hole 11;

[0029] A screw 3 is inserted into each through hole 24 , and the threaded end of each screw 3 is inserted into and threadedly connected to an opening of a corresponding threaded through hole 11 close to the screw 3 , and the head of each screw 3 is disposed in a corresponding countersunk hole 23 .

[0030] The distance a between the bottom surface of any U-shaped guide groove 21 and the bottom surface of a U-shaped spacing groove 22 located at the same height is more than 1.5 times the inner diameter of the counterbore 23 .

[0031] The width of the U-shaped guide groove 21 is equal to the width of the U-shaped spacing groove 22 and is not greater than 3 mm.

[0032] The left and right ends of the opening of the U-shaped connecting block 2 are flush with the edge of one side of the body 1 where the bucket tooth seat 4 is located so as to maximize the contact area between the bucket tooth seat 4 and the U-shaped connecting block 2 .

[0033] The length of the through hole 24 is not less than half the length of the screw 3 .

[0034] The threaded ends of the two screws 3 respectively inserted and screwed into the openings at both ends of the same threaded through hole 11 do not contact each other.

[0035] How to install the bucket tooth holder 4 for the first time:

[0036] Align the slot 41 on the tooth holder 4 with the side edge of the opening of each U-shaped connecting block 2 on the main body 1, and insert the side edge on the main body 1 into the slot 41 on the tooth holder 4. At the same time, insert the clamping plates 42 on the upper and lower sides of the slot 41 on the tooth holder 4 into the interior of the upper and lower U-shaped connecting blocks 2 in the same U-shaped connecting block combination until the bottom surface of the slot 41 contacts the side edge on the main body 1. Then, welding equipment can be used to weld between the U-shaped gap formed between the outer wall of the side of the tooth holder 4 and the inner wall of each U-shaped connecting block 2 to form a U-shaped weld, and then the tooth holder 4 can be welded between the two U-shaped connecting blocks 2 in the U-shaped connecting block combination fixed on the main body 1.

[0037] How to remove the damaged bucket tooth seat 4:

[0038] If the bucket tooth seat 4 is directly welded to the body 1, a U-shaped weld will be formed between the bucket tooth seat 4 and the body 1. When the bucket tooth seat 4 welded to the body 1 is seriously damaged and cannot be used, it must be replaced. When replacing, the U-shaped weld must be cut off with the help of a cutting tool, and then the damaged bucket tooth seat 4 can be removed, and the body 1 can continue to be used; however, when the blade of the cutting tool cuts off the U-shaped weld, it will inevitably contact the body 1, thereby damaging the body 1, thereby affecting its strength and service life; and the benefits of the utility model The tooth seat 4 is welded between two U-shaped connecting blocks 2 in the same U-shaped connecting block combination; when cutting, the blade of the cutting tool is horizontally arranged and extended into the uppermost U-shaped guide groove 21 to horizontally cut the U-shaped connecting block 2 until the blade extends into a U-shaped spacing groove 22 of the same height, and then the part of the U-shaped connecting block 2 located above the above-mentioned U-shaped guide groove 21 is cut off, and then the tooth seat 4 is pulled out to realize disassembly. During this process, the main body 1 is intact and the remaining part after cutting can still be used.

[0039] The operation method of bucket tooth holder 4 during the second installation:

[0040] Take a new bucket tooth seat 4 and place it in the same way into two U-shaped connecting blocks 2 that belong to the same U-shaped connecting block combination and have been cut. Then, welding equipment can be used to weld between the U-shaped gap formed between the outer wall of the side of the bucket tooth seat 4 and the inner wall of each U-shaped connecting block 2 to form a U-shaped weld, and then the new bucket tooth seat 4 is welded between the two cut U-shaped connecting blocks 2, so that the two cut U-shaped connecting blocks 2 can continue to be used.

[0041] Installation method of bucket tooth holder 4 during the third installation:

[0042] If the height of the U-shaped guide groove 21 at the lower position of an individual part is comparable to the position of the head of the screw 3, it cannot be cut directly at this time. Instead, each screw 3 must be unscrewed to remove the two U-shaped connecting blocks 2 and the bucket tooth seat 4 located between the two U-shaped connecting blocks 2, and then the two U-shaped connecting blocks 2 are cut in the same way. Finally, the two U-shaped connecting blocks 2 after cutting are reinstalled on the main body 1 and a new bucket tooth seat 4 is welded.

[0043] How to replace U-shaped connecting block 2:

[0044] After each U-shaped guide groove 21 is cut, it can be used once. If the bucket tooth seat 4 needs to be replaced thereafter, just unscrew each screw 3 to remove the two U-shaped connecting blocks 2 and the bucket tooth seat 4 located between the two U-shaped connecting blocks 2, then take out two new U-shaped connecting blocks 2 and use the original screws 3 and install the two new U-shaped connecting blocks 2 on the body 1 in the same way, and then weld the new bucket tooth seat 4 in the same way.

[0045] The main body 1 and the bucket tooth seat 4 of the utility model are not directly welded and fixed, but a U-shaped connecting block 2 is arranged between the two, that is, the bucket tooth seat 4 is welded to the U-shaped connecting block 2, and the U-shaped connecting block 2 is detachably fixed to the main body 1. When disassembling the bucket tooth seat 4, it is only necessary to directly cut the U-shaped connecting block 2, thereby facilitating the disassembly of the bucket tooth seat 4 while ensuring that the main body 1 has good strength and connection firmness; moreover, the main body 1 will not be damaged in the cutting process, thereby fully ensuring the structural strength of the main body 1 so that the main body 1 can reach a normal service life, and at the same time, there is no need to slow down the cutting speed in order to avoid damaging the blade, thereby improving the replacement efficiency of the bucket tooth seat 4; in addition, the U-shaped connecting block 2 can be used multiple times after cutting, thereby avoiding the U-shaped connecting block 2 being scrapped after cutting once, thereby taking into account the material utilization rate and avoiding waste.
