Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments:

as shown in fig. 1 to 3, a cement sampler comprises a sampling mandrel 1 with a tip at one end and an annular turntable 2 sleeved on the sampling mandrel 1, wherein a sampling notch 104 is formed on the sampling mandrel 1; the turntable 2 is connected with a baffle 3, the baffle 3 is wound on the sampling mandrel 1, and the baffle 3 can rotate around the sampling mandrel 1 and cover the sampling notch 104.

In this embodiment, the sampling mandrel 1 is a three-section stepped shaft, and sequentially comprises a first section shaft 101, a second section shaft 102 and a third section shaft 103 from front to back, one end of the first section shaft 101 is the end of the sampling mandrel 1 inserted into a cement bag, the other end of the first section shaft 101 is the end of the first section shaft 101 connected with the second section shaft 102, and a plurality of sampling notches 104 are uniformly formed in the middle of the first section shaft 101 along the length direction of the sampling mandrel 1; specifically, revolving stage 2 is located the other end of first section axle 101, and the interior annular surface of revolving stage 2 passes through threaded connection with first section axle 101, and the outer annular surface of revolving stage 2 has seted up the recess of a plurality of equipartitions along the circumferencial direction, feels better.

The end surface of the rotary table 2 is convexly provided with a baffle 3, and the baffle 3 is wound on the surface of the middle part of the first section shaft 101; the baffle 3 and the rotary table 2 are of an integrated structure, the baffle 3 is matched with the outer circumferential surface of the sampling mandrel 1, and the side edge of the baffle 3 is flat, so that the baffle 3 can be manually rotated under the condition that cement is extruded and does not fall off, and the cement is helped to fall into the sampling notch 104; in addition, one end of the first section shaft 101 of the sampling mandrel 1 is a pointed end, so that cement can be conveniently punctured.
