The current installation mode of the teeth of the loader shovel mainly includes bolt connection type, pin connection type and the like. The bolt connection type fixes the teeth and the tooth seat through bolt and nut, but under high frequency vibration and impact load, the bolt is prone to loosening or even breaking, which leads to the falling of the teeth, and frequent manual inspection and fastening are required, so the maintenance cost is high. The pin connection type relies on the pin shaft to knock and disassemble, which is time-consuming and laborious and easy to damage the pin hole. After long-term use, the gap between the pin shaft and the pin hole increases, causing the teeth to shake. SUMMARY

[0006] Further, the limiting assembly is an elastic limiting pin installed on the side wall of the limiting column.

[0007] Further, the elastic limiting pin is provided with a plurality of elastic limiting pins.

[0008] Further, the plug-in column and the connecting shaft are coaxially arranged.

[0009] Further, the plug-in barrel is provided with a mark point at the barrel opening, and the mark point corresponds to the through groove.

[0010] Further, the mounting seat, the plug-in barrel and the shovel tooth are provided with multiple groups, and the multiple groups of mounting seats are uniformly distributed along the bottom front edge of the bucket body.

[0011] Compared with the prior art, the utility model has the advantages of:

[0012] The application forms preliminary positioning through the cooperation of the plug-in column and the plug-in groove, the connecting shaft and the limiting plate pass through the through groove of the partition plate, the limiting ring is sleeved on the limiting column, the shovel tooth is limited between the mounting seat and the limiting assembly through the limiting assembly, two-way limiting constraint is formed, this structure design can effectively resist high-frequency vibration and impact load, avoids the shovel tooth from falling off due to loosening or gap increase, compared with traditional bolt connection or pin connection, stability is improved significantly, installation time is reduced, and maintenance efficiency is improved.

DETAILED DESCRIPTION

[0017] As Figs. 1 to 3 shown, a loader bucket, including bucket body 1 and shovel tooth 2, the bottom front edge of the bucket body 1 is fixedly connected with mounting seat 3, the mounting seat 3 is fixedly connected with plug-in barrel 4, the plug-in barrel 4 is provided with partition plate 5, the partition plate 5 divides the plug-in barrel 4 into plug-in groove 401 and cavity 402, the rear end of the shovel tooth 2 is provided with round groove 201 matched with the plug-in barrel 4, the plug-in column 6 matched with the plug-in groove 401 is arranged in the round groove 201, the end of the plug-in column 6 is fixedly connected with connecting shaft 7, the connecting shaft 7 is fixedly connected with limiting plate 8, the through groove 501 corresponding with the limiting plate 8 is formed in the partition plate 5, the limiting column 9 is arranged on the mounting seat 3, the limiting ring 10 is fixedly connected on the outside of the shovel tooth 2, the limiting ring 10 is slidably sleeved on the limiting column 9, the limiting assembly 11 is arranged on the limiting column 9, and the limiting ring 10 is located between the mounting seat 3 and the limiting assembly 11.

[0018] The limiting assembly 11 is an elastic limiting pin installed on the side wall of the limiting column 9.

[0019] The elastic limiting pin is provided with a plurality of.

[0020] The plug-in column 6 and the connecting shaft 7 are coaxially arranged.

[0021] The plug-in barrel 4 is provided with a mark point 12 at the barrel opening, and the mark point 12 corresponds to the through groove 501.
