Mechanical hand device of sampling machine and sampling machine

Abstract

The invention discloses a mechanical hand device of a sampling machine. The mechanical hand device comprises an outer sleeve and a sampling head, wherein the sampling head comprises two claw pieces, the two claw pieces are in butt joint and respectively articulated at the end parts of the outer sleeve; and the sampling head is of a duckbill structure. The two claw pieces can converge material into the outer sleeve, and after the claw pieces are closed, a material inlet of the outer sleeve is sealed, so that the sampling work is completed. The sampling head is of the duckbill structure and can form cutting type extrusion with the material so as to keep the material loose, enable the working pressure on the material, which is applied by the sampling head, to be constant basically, effectively solve the problem that the resistance of the sampling head, which is applied by the material, becomes grater and greater during the sampling and downward drilling process of the mechanical hand device and improve the smoothness in operation of the mechanical hand device. The invention further provides the sampling machine equipped with the mechanical head device of the sampling machine, and the sampling work is smoother.

Description

technical field [0001] The invention relates to the technical field of sampling equipment, in particular to a sampling machine manipulator and a sampling machine. Background technique [0002] Sampling machine (automatic sampling machine) is a mechanical device used to obtain a sample from a batch of materials whose test results can represent the entire batch of sampled materials. There are many types of sampling machines. According to different industries and different places of use, the structure of sampling machines used is also different. [0003] The sampling machines provided in the prior art are generally used in the following three structural forms, which are respectively: [0004] 1. Spiral sampling head. The spiral sampling head is mainly used for sampling granular items, and is mostly used in the coal industry, including an outer cylinder and a spiral blade, and the spiral blade is arranged in the outer cylinder. When the lifting mechanism of the sampling machi...

AI Technical Summary

Problems solved by technology

[0007] Among the above three structural types of sampling machines, the sampling machine using the spiral sampling head has a higher sampling target, and can only sample granular items, but cannot sample large items (items exceeding their theoretical sampling diameter) sampling

In the structure of the manipulator, since the claws of the manipulator are closed, they all have a cone structure. Therefore, when the manipulator drills into the material as the lifting mechanism descends, the material is gradually squeezed around, which will have a greater impact on the manipulator's descent. The resistance greatly affects the smoothness of the manipulator's work

[0008] To sum up, how to provide a manipulator device for sampling machines to overcome the problem of large material resistance during the sampling process has become an urgent problem to be solved by those skilled in the art
