Description

Technical Field

[0001] This utility model relates to the field of excavator parts and tools, specifically an excavator bucket auxiliary scraper device. Background Technology

[0002] An excavator, also known as a digger, 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 materials excavated by excavators are mainly soil, coal, silt, and pre-loosened soil and rock. Scrapers are installed on the bucket for leveling operations, such as leveling the bottom of ditches during construction or leveling foundations during excavation. Traditionally, the bucket auxiliary scraper device is directly welded to the bucket. Each installation requires a welding machine, and each disassembly requires a cutting machine. This process is time-consuming and labor-intensive, and can damage the flatness of the bucket. How to quickly and conveniently install and remove the bucket auxiliary scraper is a technical problem that urgently needs to be solved.

[0003] To address the aforementioned issues, we propose an auxiliary scraper device for excavator buckets, which improves upon the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an auxiliary scraper device for excavator buckets. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution:

[0005] This utility model discloses an auxiliary scraper device for an excavator bucket, comprising a main scraper, with detachable extension plates connected to both ends of the main scraper. Two digging tooth sleeves are welded to the top end face of the main scraper, and a connecting plate is welded to the digging tooth sleeve. A pressing plate is welded to the inner top of the connecting plate, and two locking bolts are provided on the pressing plate. Grooves are provided at both ends of the main scraper, and a plug-in plate is provided at the connecting end of the extension plate. The extension plate is connected to the main scraper by two locking bolts.

[0006] Preferably, a welding plate is also fitted onto the locking bolt.

[0007] Preferably, the tooth sleeve can be fitted onto the teeth of the bucket.

[0008] Preferably, the length of the main scraper is equal to the length of the bucket.

[0009] Preferably, the length of the extension plate is 30cm.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] By installing two tooth sleeves on the main scraper, the auxiliary scraper can be installed by fitting the tooth sleeves onto the teeth, increasing the stability of the scraper installation. The tooth sleeves are equipped with a connecting plate, a pressing plate, a locking bolt, and a welding plate. During installation, the welding plate is welded to the bucket, and the auxiliary scraper device is fixed to the welding plate using the locking bolt, achieving a secure installation. Disassembly is simple; just remove the locking bolt. This design of the excavator bucket auxiliary scraper device is time-saving, labor-saving, convenient, and quick to install and remove, minimizing damage to the bucket's flatness. Furthermore, the overall length of the scraper can be increased as needed, making it extremely convenient to use and greatly improving its practicality. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example

[0021] like Figure 1-5As shown, an excavator bucket auxiliary scraper device includes a main scraper 1, with detachable extension plates 2 connected to both ends of the main scraper 1. Two tooth sleeves 3 are welded to the top end face of the main scraper 1, and a connecting plate 4 is welded to the tooth sleeve 3. A pressing plate 5 is welded to the inner top of the connecting plate 4, and two locking bolts 6 are provided on the pressing plate 5. Grooves 7 are provided at both ends of the main scraper 1, and a plug-in plate 8 is provided at the connecting end of the extension plate 2. The extension plate 2 and the main scraper 1 are connected by two locking bolts 9 to form an integral excavator bucket auxiliary scraper device structure. It is time-saving and labor-saving to disassemble and assemble, convenient and quick, and does not easily damage the flatness of the bucket. At the same time, the overall length of the scraper can be increased according to the needs, making it extremely convenient to use. A welding plate 10 is also fitted on the locking bolts 6 for welding to the connecting device on the bucket. The tooth sleeves 3 can be fitted onto the teeth of the bucket. The length of the main scraper 1 is equal to the length of the bucket, and the length of the extension plate 2 is 30cm, which has a large adjustment range and helps to improve the leveling speed.

[0022] The principle and advantages of this utility model are as follows: Figure 3 As shown, first, put the tooth sleeve 3 on the tooth, mark the position of the welding plate 10 on the inner wall of the bottom of the bucket, then weld the welding plate 10 to the inner wall of the bottom of the bucket, and then tighten the locking bolt 6 to firmly fix the pressing plate 5 on the welding plate 10. Thus, the auxiliary scraper device of the excavator bucket is installed on the bucket. When it is necessary to extend the length of the main scraper 1, insert the plug plate 8 at the end of the extension plate 2 into the groove 7 of the main scraper 1, and then use the locking bolt 9 to connect and fix the two. Disassembly When installing the excavator bucket auxiliary scraper device, first unscrew the locking bolt 6 and pull the tooth sleeve 3 outward to detach the device from the bucket. When reinstalling, simply put on the tooth sleeve 3 and use the locking bolt 6 to fix the pressure plate 5 onto the welding plate 10. The excavator bucket auxiliary scraper device with this structural design is time-saving and labor-saving to disassemble and assemble, convenient and quick, and does not easily damage the flatness of the bucket. At the same time, the overall length of the scraper can be increased according to needs, making it extremely convenient to use and greatly improving its practicality.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
