Problems solved by technology

[0002] Many drilling devices at this stage use the auger bit to rotate the underground soil out of the borehole through the auger bit, but when encountering a hole with a large amount of silt, the efficiency of the drilling equipment will be greatly reduced, because it is taken away. The silt will slide back into the cavity, and it is not easy to bring out, and the speed of bringing out is slow, and the silt drilled out of the hole is slow to solidify, which leads to the extension of the work area

Abstract

The invention discloses a well drilling device for automatic desilting. The device comprises a shell, wherein the shell is internally provided with a processing cavity with a downward opening, the right side of the upper portion of the processing cavity communicates with a transmission cavity, the lower portion of the transmission cavity communicates with an extension cavity, a gear cavity is formed in the rear end wall of the extension cavity, a rotating well block is slidably mounted in the processing cavity, a storage cavity with a downward opening is formed in the rotating shell block, anda stop block is fixedly arranged on the lower end face of the left side of the rotating well block . The device is used for well drilling on the deep ground bottom or a river channel mouth containinga large amount of silt, in a well drilling process, the silt therein is rotated and simultaneously carried into the device to be taken away, so that the condition that a well drilling speed is causedlow due to the fact that the silt remains thereunder is avoided, in addition, the taken-away silt can be quickly dried and prevented from falling into a well drilled hole, and transportation is facilitated.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a drilling device for automatic dredging. Background technique [0002] Many drilling devices at this stage use the auger bit to rotate the underground soil out of the borehole through the auger bit, but when encountering a hole with a large amount of silt, the efficiency of the drilling equipment will be greatly reduced, because it is taken away. The silt will slide down into the cavity again, and it is not easy to bring out, and the speed of bringing out is slow, and the silt drilled out of the hole solidifies slowly, resulting in the extension of the work area. [0003] This application describes a drilling device for automatic dredging, which can solve the above problems. Contents of the invention [0004] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a drilling device for automatic dredging, which can overcome the above-m...
