AI Technical Summary

Technical Problem

Existing drilling cuttings sampling equipment suffers from problems such as incomplete cleaning, slow sampling speed, and unreliable data during the cleaning process. This is mainly due to the lack of an effective vibration and horizontal agitation mechanism, which leads to cuttings accumulation and cleaning dead zones.

Method used

The first motor drives the transmission shaft to rotate and generates eccentric centrifugal force through the eccentric block. Combined with the second motor driving the cam to rotate, the transmission shaft vibrates up and down and moves horizontally back and forth. With the help of the turner and fan-shaped plate, the rock chips are turned over and spread flat, ensuring that the cleaning fluid penetrates deeply into the gaps between the rock chips.

Benefits of technology

It improved the cleaning quality, avoided localized accumulation and cleaning dead spots, increased the sampling speed, reduced labor intensity, and provided a more reliable data foundation.

Abstract

This invention relates to the field of rock cuttings sampling technology and discloses an automated drilling rock cuttings sampling device, including a side plate with a cleaning box installed inside. A cover plate is inserted into the feed inlet, and the upper part of the inner side is hollow. A locking block is inserted into one side plate, with guide shafts connected to both sides of the locking block and fitted with first springs. Bearings are installed externally, and a transmission shaft is inserted into the bearings and locking block. A first motor is mounted on the outside of the locking block, and its rotor is coaxially connected to the outer end of the transmission shaft. An eccentric block is mounted externally on the transmission shaft, and a connecting rod is mounted circumferentially. The outer end of the connecting rod is connected to a lever plate, and an inner rod is inserted internally. A slot is opened on the surface of the transmission shaft, into which a mounting bracket is inserted and connected to the inner rod. A mounting plate is connected to the other side of the locking block. A second motor is mounted on the lower surface of the mounting plate, with its rotor penetrating the mounting plate and coaxially connected to a cam at its top. The device uses the first motor to drive the transmission shaft to rotate and vibrate up and down, causing the lever plate to flip and lift the rock cuttings. The second motor drives the cam to push the inner rod in horizontal reciprocating motion, achieving multi-directional agitation and improving the cleaning effect and sampling speed.
