Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, in particular to a bucket tooth component. Background Art

[0002] At present, excavators are often used in construction machinery. Excavators generally include bucket teeth and tooth seats, which need to be fixedly connected with pins. That is to say, both the tooth seat and the bucket teeth must have pin holes that match the pins, and the tooth seat is welded to the edge of the excavator bucket.

[0003] At present, there is a groove in the middle of the commonly used pin, and a C-shaped retaining ring is stuck on the groove. The inner diameter of the retaining ring is slightly larger than the diameter of the pin groove, and the outer diameter is slightly larger than the inner diameter of the pin hole. When installing, the pin is knocked to make it pass through the pin hole of the tooth seat, and the friction between the outer diameter of the retaining ring and the inner wall of the pin hole is stuck, so that the pin is fixed in the pin hole, and the retaining tooth is fixedly connected to the tooth seat through the pin and the retaining ring. However, this connection structure between the bucket tooth and the tooth seat is very inconvenient to install and disassemble. Utility Model Content

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] like Figure 1-5 As shown, the bucket tooth assembly includes: a tooth seat 1, a bucket tooth 2 and a connecting piece. The tooth seat 1 and the bucket tooth 2 are both provided with a lifting ring 3, and the connecting piece is used for detachably connecting the bucket tooth and the tooth seat.

[0028] Specifically, the connecting piece includes a connecting shaft 4, a clamping ring 5 and a locking bolt 6. The tooth seat 1 is provided with a first mounting hole 11, and the bucket tooth 2 is provided with a second mounting hole 21. When the bucket tooth is inserted into the tooth seat, the first mounting hole and the second mounting hole are aligned, and the connecting shaft can pass through the first mounting hole and the second mounting hole; the tooth seat 1 has a mounting groove 12 for the clamping ring to be inserted, and the mounting groove is provided with a second protrusion 13. A limiting groove 51 is provided on the outer wall of the clamping ring 5, and the limiting groove can be inserted into the second protrusion to prevent the clamping ring from being stuck in the mounting groove. The connecting shaft 4 is provided with a third mounting hole 41 and a threaded hole 42, and the locking bolt can pass through the third mounting hole and be screwed into the threaded hole; the retaining ring 5 is provided with a first protrusion 52 on the inner wall, and the connecting shaft 4 is provided with a sliding groove 43 and a clamping groove 44, the first protrusion can be fitted with the sliding groove, and when the first protrusion is fitted with the sliding groove, the connecting shaft can slide relative to the retaining ring, and the first protrusion can be clamped into the clamping groove; the first protrusion 52 is provided with a locking groove 521, and when the locking bolt enters the threaded hole, the locking bolt is clamped into the locking groove.

[0029] When installing the bucket teeth, first insert the clamping ring into the installation groove, then align the first installation hole and the second installation hole and insert the connecting shaft, and then rotate the connecting shaft so that the first protrusion is inserted into the clamping groove, and then screw the locking bolt into the threaded hole, so that a part of the locking bolt is inserted into the clamping groove, thereby completing the locking of the connecting shaft to prevent the connecting shaft from rotating out; when the bucket teeth need to be replaced, unscrew the locking bolt, and then rotate the connecting shaft so that the first protrusion fits into the sliding groove, and the connecting shaft can be pulled out, which is very convenient to disassemble.

[0030] In other embodiments, a hexagonal hole 43 is provided at the end of the connecting shaft 4 to facilitate the rotation of the connecting shaft.

[0031] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the embodiments of the present disclosure.
