Excavators and bulldozers are often used when digging ditches.

[0003] When digging ditches, excavators use special excavator buckets and replace different buckets according to different excavation needs and working environments. Standard buckets are suitable for digging loose soils, narrow buckets are suitable for narrow spaces or ditches that require precise digging, and rock buckets are suitable for digging ditches containing rocks and hard soils. Correct selection and use of excavator buckets are crucial to improving excavation efficiency and ensuring work quality and safety.

[0047] Working principle: When the angle of the side panel 3 needs to be adjusted, first remove the clamping block 3 7 from the guide groove 6, then rotate the rotating handle 19 to drive the third rotating shaft 13 to rotate, thereby driving the second gear 14 to rotate and then the first gear 12 to rotate, so that the support block 11 can rotate together, thereby rotating the telescopic rod 9 outward or inward, so that the side panel 3 can rotate along the first rotating shaft 4. At the same time, the telescopic rod 9 is extended and retracted to adapt to its rotation angle to prevent breakage. After rotating to the appropriate angle, the clamping block 3 7 is inserted into the guide groove 6 so that it can be inserted into the gap formed by the multiple connecting rods 15. The rotation of the second gear 14 is blocked, thereby preventing the rotation of the third rotating shaft 13;

[0048] When the wear block 207 is severely worn after long-term use, first pull the handle 205 to squeeze the spring 1 206 of the block 204 so that it can be retracted into the sliding block 201, thereby disengaging the block 204 from the engagement with the slot 208, and then push the sliding block 201 into the slide slot 1 202 to return it to the slide slot 1 202, and finally pull the block 1 203 out of the slide slot 209, so that the wear block 207 can be disengaged from the bucket 1 and taken out for replacement.

[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
