The invention discloses an air reverse circulation continuous sampling reduction device for geological prospecting, and belongs to the field of drilling machine auxiliary tools in geological prospecting machines. The device comprises a trailer and a tower. The tower is installed on the trailer. The trailer is provided with a tower erection oil cylinder. The tower is fixedly provided with a whirl barrel, a slag accumulation barrel and a reduction barrel in sequence from top to bottom. The whirl barrel is provided with a slag inlet pipe and an exhaust pipe. A hollow center shaft is installed on the reaction barrel. A long-strip hole is formed in the center shaft. The center shaft is sleeved with a rotary basket. The rotary basket is provided with a sleeve with which the center shaft is sleeved. The sleeve is provided with a long-strip hole corresponding to the long-strip hole in the center shaft. The rotary basket is provided with a plurality of sampling baskets. The sampling baskets are provided with long-strip holes corresponding to the long-strip hole in the rotary basket. A sampling pipe and a slag discharge pipe are installed under the center shaft. The air reverse circulation continuous sampling reduction device can achieve the functions of rock sample storage, isolation, reduction according to required proportions, water removal, dry-wet separation and the like. The reduction device is simple in structure, powerful in function, totally closed and small in environmental pollution.
Description
technical field [0001] The invention belongs to the field of drilling rig auxiliary tools in geological exploration machinery, and in particular relates to a shrinking collection device for rapidly and continuously obtaining rock samples during the construction process of air reverse circulation continuous sampling. Background technique [0002] With the rapid development of the national economy, the demand for various resources has also increased accordingly, and rapid exploration and acquisition of rock samples has become an inevitable trend. At present, the commonly used exploration technology in our country is diamond extraction to obtain cores or rope coring. The extraction of cores requires all the drilling tools in the hole to take out the cores after each round, which is very inefficient. The wireline coring method can take out the core without raising the drilling tool, and the efficiency has been greatly improved. However, the construction efficiency in deep holes ...
