A concrete chloride ion content testing machine

Abstract

The invention relates to sampling equipment for concrete tests, and particularly relates to a powder sampling machine for testing the chlorine ion content of concrete. The powder sampling machine comprises a test sample clamp and a grinding chuck for a straight grinder. The powder sampling machine is characterized in that the test sample clamp consists of a substrate and a footstock, a through hole is formed in the center of the footstock, the grinding chuck for the straight grinder consists of a fixing device and a regulation fixing device, the fixing device is fixed on the straight grinder, and the regulation fixing device slides up and down on the fixing device so as to be stretched and fixed on the fixing device. The powder sampling machine has the beneficial effects that the fixing rate of test pieces can be effectively improved, the fixed test pieces are stable and reliable, and the test accuracy and speed are increased; the chuck for the straight grinder is stretched through a slide way, thus being easy to operate, stable to run, more durable, and capable of being recycled.

Description

(1) Technical field [0001] The invention relates to a sampling device for concrete testing, in particular to a concrete chlorine ion content testing powder taking machine. (2) Background technology [0002] In the prior art, the sample sample processing equipment for the concrete chloride ion content sample has no sample clamping and fixing clamping device, and the test piece cannot be stably fixed, and is carried out by pressing the human body. At the same time, the drill bit of the straight grinder expands and contracts through rotation, and the sample powder during the sample processing process fills the rotating thread, hinders the rotation, and is not easy to operate. (3) Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a concrete chlorine ion content test powder extractor that can quickly fix the test piece, is convenient to install and disassemble, has high test accuracy, can be recycled, is...
