The utility model will be further described with reference to the accompanying drawings, which are only illustrative and explanatory of the utility model, and are not restrictive of the scope of the utility model.
FIG. 1 is a schematic diagram of a hydraulic sample withdrawal device according to the present utility model;
wherein:
10-coring an inner tube; 11-sample; 20-sampling joint; 30-connecting pipes; 40-liquid pressure pump.
Detailed Description
The following detailed description is, however, not intended to limit the scope of the utility model to the particular embodiments.
The utility model provides a hydraulic sample withdrawal device of an audio vibration environment-friendly drilling machine, which comprises a sample withdrawal connector 20 and a liquid pressure pump 40, wherein the sample withdrawal connector 20 is provided with two communicated interfaces, one interface is connected with one end of a core taking inner tube 10 after sampling, which is not provided with a drill bit, and the other interface is connected with a liquid outlet of the liquid pressure pump 40.
In this way, after the sampling-completed coring inner tube 10 is lifted to the ground, one end of the coring inner tube 10 is connected to the hydraulic pump 40 through the sample withdrawal joint 20, and after the hydraulic pump 40 is started, the sample 11 in the coring inner tube 10 is pushed out from the other end of the coring inner tube 10 by the pump pressure of the hydraulic pump 40, thereby completing the coring sample withdrawal operation.
Preferably, the sample withdrawal device may further include a connection pipe 30, wherein the connection pipe 30 connects the sample withdrawal joint 20 and the hydraulic pump 40, and the connection pipe 30 is provided so that the coring inner pipe 10 can be kept on the ground during sample withdrawal.
The liquid pressure pump may be a slurry pump or a water pump, and after the slurry pump or water pump is operated, water or slurry connected to one end thereof may be pressed into the coring inner tube 10 for pressing out the sample 11.
Preferably, both the interfaces of the sample withdrawal connector 20 are threaded interfaces.
The sample removing method of the device comprises the following steps: after the sampling-completed coring inner tube 10 is lifted to the surface, one end of the coring inner tube 10 is connected to a liquid pressure pump 40, and the sample 11 in the coring inner tube 10 is pressed out by the pump pressure of the liquid pressure pump 40.
