[0006] On the basis of the above technical scheme, the replaceable bucket tooth module includes a tooth seat, an insert block, a first embedding groove, a bucket tooth limiting pad, a three-section pin shaft socket, a pin shaft limiting ring, a pin shaft, and a bucket tooth. An insert block with an integrated rectangular structure is installed in the middle of the right end of the tooth seat. A first embedding groove is opened at the top of the insert block and a bucket tooth limiting pad with a magnetic suction connection is installed on the inside. A three-section pin shaft socket with a through structure is opened in the middle of the front and rear sections of the insert block. A pin shaft limiting ring with a plug-in connection is installed on the inside of the three-section pin shaft socket. A plug-in pin is installed on the inside of the three-section pin shaft socket and the pin shaft limiting ring, and the bucket tooth plug-inly matched with the insert block is limited and fixed.

[0007] On the basis of the above technical scheme, the bucket tooth limit pad includes an inserting table, a second embedding groove, a rubber pad, a guide box, a magnetic block, a guide hole, a movable rubber block, and a spring telescopic rod. A second embedding groove with a rectangular structure is opened at the top of the inserting table, and a rubber pad fixed by bonding is installed on the inner side of the second embedding groove. Symmetrically distributed guide boxes are installed on both sides of the bottom end of the inserting table, and magnetic blocks with rectangular structures are installed on the bottom ends of the guide boxes.
