PRACTICAL TYPE OF OIL-PRESSURIZED FIXED-PISTON SAMPLER

摘要

The present invention is a conventional fixed piston hydraulic sampler operation among the sampler type is easy sample the quality is poor, by press-fit type sampler can obtain undisturbed samples of good quality, but the operation is difficult to improve the point-consuming operation hours, to include all the advantages hydraulic expressions hydraulic sampler that has, easy operation and while the normal type can be used to provide hydraulic piston fixed to the sampler so as to ensure the quality of the sample. A sampling unit for sampling, and to ensure that the tube is moved in the downward direction when the sample is taken normal type hydraulic piston fixed sampler according to the present invention is charged into a ball drilling, the movable piston is moved in the downward direction; But it is connected to the sampling unit and a controller for controlling the oil pressure to the actuating piston, and air movement in the vertical direction; The sampling unit is charged into a ball drilling, and a piston movable in the inner case to enable the piston to move up and down; And a head coupled to the upper side of the piston case having an air entrance and an oil entrance is formed to allow air and oil out; The piston is disposed inside the case, one side is coupled to the movable piston is moved to the lower side when the piston is moved in the downward direction and the actuating tube for sampling for sampling; And fixing the piston to prevent the air in the sample is disposed inside the tube for collecting a sample collected during collection of the sample; Is disposed inside the tube of the piston case, and the sampling is provided a movable piston to enable vertical movement in the interior of the piston case, one side passes through the movable piston is fixed and the head, the other side the said fixed piston, and fixed and fixed to the piston rod such that the movable support; The fixing is arranged on the inside of the load side is exposed to the upper side of the head, characterized in that it comprises a release rod coupled to the other side the said fixed piston. ;
