Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sand bailing drill buckets, and particularly relates to an anti-skidding sand bailing drill bucket. Background Art
[0002] In the fields of geological exploration, building construction, etc., rotary drilling rigs are indispensable tools in drilling operations. The sand bailing drill bucket is a type of rotary drill bit, mainly used in the construction of rotary drilling rigs. The design and selection of the sand bailing bucket directly affect the drilling efficiency and construction speed. The sand bailing drill buckets currently on the market generally adopt a drill tooth structure that is integrated with the base plate. Although this structure ensures the strength and stability of the drill bucket to a certain extent, it has obvious shortcomings. Since the drill teeth are the working end of the drill bit during the drilling process and are in direct contact with rocks and soil, the drill teeth are wearing parts and need to be replaced frequently. Replacing the integrated drill tooth structure not only requires disassembling the entire drill bucket, but also the replacement process is complicated and time-consuming, resulting in a significant increase in maintenance costs and downtime. In addition, the replaced drill bucket needs to be professionally repaired and calibrated, further increasing the difficulty and cost of secondary use. Therefore, the utility model proposes a sand bailing drill bucket with a simple structure and convenient and quick replacement of drill teeth, so as to reduce maintenance costs, shorten maintenance time, and improve the efficiency of drilling operations.
[0003] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] When the drill teeth are worn or damaged during drilling operations, the utility model can quickly replace the tooth sleeve, thereby reducing the interruption time caused by the replacement of the entire drill teeth and ensuring the continuity and reliability of the drilling operation. The designed quick-change structure of the tooth seat and tooth sleeve socket eliminates the need for operators to perform complex disassembly and installation processes, greatly reducing labor intensity and operational difficulty, improving operational efficiency, and reducing maintenance time and costs. Damage to the drilling rig engine caused by excessive wear of the drill teeth due to overload is avoided, thereby extending the service life of the entire sand drill bucket. By providing a centering point, the contact area between the drill bucket and the ground is reduced, preventing the entire drill bucket from slipping during drilling.
