Problems solved by technology
However, the fan wheel in the vacuum cleaner will vibrate when it moves at high speed, which not only produces noise, but also interferes with the work of the down-the-hole drilling rig itself, especially the vacuum motor (especially the hydraulic motor) is easily damaged. This kind of vibration will cause damage to the motor, directly affect the service life of the vacuum cleaner, and also affect the working efficiency of the down-the-hole drilling rig

The invention discloses a dust-collecting motor base structure for a down-the-hole drill. The dust-collecting motor base structure comprises a dust-collecting fan and a dust-collecting motor; a wind wheel is arranged in the dust-collecting fan; a connecting base is arranged between the dust-collecting fan and the dust-collecting motor; the connecting base comprises a supporting frame connected with the dust-collecting fan and a bearing base; a bearing and a motor transmission shaft are arranged in the bearing base; an input gear part is arranged at the upper end of the motor transmission shaft; an output gear part is arranged at the lower end of the dust-collecting motor; and an inner-tooth slide sleeve part sleeves the input gear part of the motor transmission shaft and the output gear part of the dust-collecting motor. When the motor base structure works for the down-the-hole drill, a dust collector generates noises and vibration in a dust-collecting process; the inner-tooth slide sleeve part is designed between the dust-collecting motor and the motor transmission shaft, so that noises are favorably reduced and influences of vibration on a motor can be reduced favorably when a decomposition dust collector works, and therefore, the working service life of the dust collector is prolonged favorably, and the working efficiency of the down-the-hole drill is also improved.
Description
technical field [0001] The invention relates to the technical field of motors, in particular to a dust suction motor seat structure for a down-the-hole drilling machine. Background technique [0002] Down-the-hole drilling rigs are widely used in large, medium and small mines, hydropower, transportation and other earthwork excavation and blasting projects, and can also be used in ports, waterways and other underwater rock perforation blasting. The energy loss caused by the impact energy transmitted by the drill rod is small, thereby reducing the impact of hole depth on rock drilling efficiency. When the down-the-hole drilling rig is drilling, it will produce a large amount of rock dust, pollute the environment, endanger the operator's personal health, affect the operator's sight, hinder the operation, and affect the quality of the drilling. Therefore, the down-the-hole drilling rig needs to be equipped with a vacuum cleaner. However, the fan wheel in the vacuum cleaner wil...
