As shown in fig. 2, the tooth holder 2 is formed with an opening that allows the cutting edge of the back plate to be inserted to achieve the connection of the tooth holder 2 with the bucket 4.
Wherein, tooth 1 is rod-like, strip etc. and can rotate about its length direction's axis relative to toothholder 2, and this allows when scraper bucket 4 excavates material, under the collision of material, friction effect, tooth 1 rotates relative to scraper bucket 4, reduces tooth 1 relative to the friction of material to better protection tooth 1.
In this scheme, the bucket tooth can rotate for the toothholder, can turn into the friction between bucket tooth and the structure on the scraper bowl with the friction between bucket tooth and the material to a certain extent to reduce the wearing and tearing of material to the bucket tooth, prolonged the life of bucket tooth.
In addition, the tooth assembly includes a tooth shoe 3 mounted on the tooth holder 2, the tooth 1 is mounted on the tooth shoe 3, and the tooth shoe 3 is rotatable relative to the tooth holder 2 about an axis along the longitudinal direction of the tooth 1. The tooth shoe 3 is a mounting medium between the tooth 1 and the tooth holder 2, and relative rotation between the tooth 1 and the tooth holder 2 can be realized through relative rotation between the tooth 1 and the tooth shoe 3. Among them, the tooth shoe 3 is a small-sized member, which is easily replaced after being worn.
In addition, the tooth 1 is rotatable about an axis along its length relative to the tooth shoe 3. That is to say, when the material drives bucket tooth 1 and rotates for toothholder 2 relatively, this kind of rotation can be realized through rotation between bucket tooth 1 and the toothholder 3 and the rotation between tooth boots 3 and toothholder 2, and at this in-process, the rotation range of bucket tooth 1 and the rotation range of toothholder 2 all reduce for the wearing and tearing of bucket tooth 1 and toothholder 2 reduce, with the wearing and tearing of bucket tooth 1 and toothholder 2 transferred in toothholder 3, be about to wear and tear and transfer in the part of being convenient for to change. Lubricating oil, lubricating grease and the like can be coated between the bucket teeth 1 and the tooth shoes 3 and between the tooth shoes 3 and the tooth base 2 so as to reduce friction acting force.
In particular, the tooth shoe 3 is of a tubular structure. The tooth shoe 3 is formed substantially in the shape of a circular pipe which can be inserted into a circular hole of the tooth holder 2 and allows the tooth 1 to be inserted into a circular hole of the tooth shoe 3, enabling relative rotation of the tooth 1 and the tooth shoe 3 and relative rotation of the tooth shoe 3 and the tooth holder 2.
