Abstract

The invention relates to the technical field of coal detection sampling, and discloses an intelligent quantitative sampler for coal detection, the intelligent quantitative sampler comprises a cylinder, a screw rod, a driving motor, a discharge pipe, a connecting pipe and a sampling box, the screw rod is rotatably mounted at the top end in the cylinder, the driving motor is mounted at the top end of the cylinder, and the discharge pipe is mounted on the annular side surface of the cylinder; a discharging opening is formed in the annular side face of the cylinder and is aligned to the discharge pipe, the connecting pipe is installed on the discharge pipe, and the sampling box is fixedly installed at the bottom end of the connecting pipe. An electric push rod can drive an upper limiting ring to move, the upper limiting ring moves to drive an end cover to move through a fixing ring, then a movable plate is driven to move, meanwhile, the electric push rod can work to drive a rack to move, then a transmission gear and a rotating pin are driven to rotate, and closing of a bearing shell is achieved; and a driven gear can be driven by a driving gear to rotate, so that a fixing block and the cylinder move downwards together.

Description

technical field [0001] The invention relates to the technical field of coal samplers, in particular to an intelligent quantitative sampler for coal detection. Background technique [0002] Coal quality testing instrument is an instrument used to determine the content of various elements in coal. The main procedures include coal sampling, shrinking, crushing, sample preparation, and coal testing. The main testing items: total sulfur, calorific value, coal moisture, ash, Volatile matter, fixed carbon, carbon, hydrogen, ash melting, slag carbon content, coking coal, petroleum coke, briquette and other related items are measured. The coal sampler drives the coal to move through the rotation of the screw rod, and then the coal passes through the discharge pipe and the connection The tube enters the interior of the sampling box, and the coal sample is tested for moisture. [0003] The quantitative sampler for coal detection currently used has certain defects, and lacks the conven...
