Description

Technical Field

[0001] This utility model relates to the field of excavator tooth holder technology, specifically an excavator tooth holder resistant to impact and wear. Background Technology

[0002] An excavator, also known as a digging machine or excavator bucket, is an earthmoving machine that uses a bucket to excavate materials above or below the machine's bearing surface and load them into transport vehicles or unload them into a stockpile. The excavator bucket is equipped with tooth holders and bucket teeth for digging.

[0003] During the use of excavators, the toothed seats are easily impacted by hard objects during the excavation process, which can lead to the toothed seats falling off. There are no corresponding solutions for the toothed seats during daily use, which reduces their service life. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this invention is to provide an excavator tooth holder resistant to impact and wear, thereby resolving the issues raised in the background section.

[0005] To achieve the above objectives, this utility model proposes an impact-resistant excavator tooth holder, including a bucket, wherein an impact-resistant component is provided on one side of the bucket;

[0006] The impact-resistant component includes multiple first grooves formed on the bottom of one side of the bucket. Each first groove has a strip groove on both sides of its inner wall. A slide rod is fixedly connected to the inner wall of each strip groove. A slider is slidably connected to the outer wall of each slide rod. A spring is sleeved on one side of the outer wall of each slide rod. A movable block is fixedly connected between every two sliders. A toothed seat body is fixedly connected to one side of each movable block.

[0007] In one example, a second groove is provided at both ends of one side of the bucket, and a first connecting rod is fixedly connected to the inner wall of each of the two second grooves. A fixing rod is rotatably connected to the outer wall of each of the two first connecting rods, and the other side of the fixing rod is fixedly connected to one side of the tooth seat body.

[0008] In one example, a second connecting rod is fixedly connected to one side of every two adjacent toothed bodies.

[0009] In one example, each of the toothed bodies has a first circular hole at its top.

[0010] In one example, the outer wall of each of the toothed bodies is fitted with a wear-resistant pad, and the top of each wear-resistant pad is provided with a second circular hole, and the second circular hole is directly opposite the position of the first circular hole.

[0011] In one example, both ends of the tooth base body are fixedly connected to connecting plates, one side of each connecting plate is provided with a threaded hole, and the bottom of each connecting plate is fixedly connected to a rubber pad.

[0012] The impact- and wear-resistant excavator tooth holder proposed in this utility model can bring the following beneficial effects:

[0013] This type of impact and wear resistant excavator tooth holder, through a first groove, strip groove, slide bar, slider, spring, movable block, and tooth holder body set on one side of the bucket, allows the connection between the tooth holder body and the bucket to be movable during use. This enables partial buffering when digging into hard objects, thereby preventing the tooth holder body from breaking during use.

[0014] This type of impact and wear resistant excavator tooth holder, through a first circular hole, a wear-resistant pad, a second circular hole, a connecting plate, a threaded hole, and a rubber pad set on the top of the tooth holder body, allows the wear-resistant pad to be fitted outside the tooth holder body during use and fixed by bolts passing through the second circular hole and the first circular hole. This provides better protection for the tooth holder body during excavation, improving its wear resistance during use. Furthermore, the tooth holder body is connected to the bucket through the connecting plate. The longitudinal connection of the connecting plate and the lateral connection of the first connecting rod make the connection more stable during the connection process, preventing the risk of detachment and extending the service life of the tooth holder body during use.

An impact-resistant component is provided on one side of the bucket 1. The impact-resistant component includes multiple first grooves 2 formed at the bottom of one side of the bucket 1. Each first groove 2 has a strip groove 3 on both sides of its inner wall. A slide rod 4 is fixedly connected to the inner wall of each strip groove 3. A slider 5 is slidably connected to the outer wall of each slide rod 4. A spring 6 is sleeved on one side of the outer wall of each slide rod 4. A movable block 7 is fixedly connected between every two sliders 5. A tooth holder body 8 is fixedly connected to one side of each movable block 7. Through the first grooves 2, strip grooves 3, slide rods 4, sliders 5, springs 6, movable blocks 7, and tooth holder body 8 on one side of the bucket 1, the connection between the tooth holder body 8 and the bucket 1 is movable during use.
