[0002] Drilling equipment refers to mechanical devices and equipment used in specific working conditions such as drilling construction. It mainly consists of drilling rigs, mud pumps and mud purification equipment, mud mixers, drilling towers, etc. In geological exploration projects, drilling equipment is needed to directly penetrate underground rock formations to obtain the required engineering geological conditions data;

[0003] In existing drilling equipment, since the drill rod needs to be subjected to downward squeezing force and rotation force into the ground, the mounting sleeve connecting the top of the drill rod to the rotating motor will be subject to great resistance. The simple connection on traditional drilling equipment can easily cause damage to the mounting sleeve below the rotating motor, resulting in a short service life and affecting the drilling efficiency. At the same time, when the drill rod enters the ground and is taken out, mud will adhere to its surface, making it difficult to clean. Therefore, we propose a drilling equipment to solve the above problems. Utility Model Content
