Problems solved by technology

[0004] The present invention aims at entering the deep zone of coal in a rotating manner in the prior art. When encountering coal with a large volume, the flow effect generated by the rotating torque is mostly used to make the large coal deviate from the sampling line, resulting in incorrect sampling. Integrity, large differences, and after sampling, not only is it easy to leak, but at the same time, after the sampling is completed, it is not convenient for the staff to intuitively understand the problems existing in the quality of each coal layer. A sampling head for coal detection is provided. and how to use it

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] A sampling head for coal detection and its use method, such as Figure 1-Figure 10 As shown, the outer sampling cylinder 1 is included, the inner side of the outer sampling cylinder 1 is set with the inner sampling cylinder 3, and the top of the inner sampling cylinder 3 is fixedly connected with the top of the inner side of the outer sampling cylinder 1, and the outer sampling cylinder The interlayer formed between 1 and the inner sampling barrel 3 is provided with a sampling tube 12, and the outer contour surface of the sampling tube 12 corresponds to the inner side wall of the outer sampling barrel 1. A telescopic groove 14 is provided, and the inner sleeve of the telescopic groove 14 is Connected with a telescopic seat 15, one side of the telescopic seat 15 is fixedly connected to the end face inside the telescopic slot 14 through a...

Abstract

The invention relates to the technical field of commercial coal sampling machines, and discloses a sampling head for coal detection and a use method thereof. The sampling head comprises an outer side sampling charging barrel, and the inner side of the outer side sampling charging barrel is sleeved with an inner side sampling charging barrel. Through mutual cooperation of structures such as an elastic hinge, a conical body, a gear, a toothed plate, a hydraulic cylinder, a second supporting spring, an elastic supporting device, an outer side reinforcing ring and an inner side reinforcing ring, a direct insertion mode is used for replacing the traditional rotary insertion mode, so that the coal flowing condition can be avoided, and large coal blocks are crushed in the positive direction; Smooth penetration of the outer side sampling charging barrel and the inner side sampling charging barrel is guaranteed, sampling integrity on a sampling site vertical line is also guaranteed, leakage is avoided after sampling, in addition, the transparent body is arranged on the sampling pipe, the appearance quality of coal at each layer can be conveniently and directly observed, and when the quality goes wrong, the sampling equipment can be matched with a new sampling pipe to continue sampling work.

Description

technical field [0001] The invention relates to the technical field of commercial coal sampling machines, in particular to a sampling head for coal detection and a usage method thereof. Background technique [0002] Sampling machine (automatic sampling machine) is a 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, different industries, different places The structural form of the sampling machine is also different. Generally, according to the structural form and application occasion, it can be roughly divided into: compartment (car, train) sampling machine, pipeline sampling machine, belt sampling machine (head, middle), etc., generally used in bulk. Sampling during the transportation and transshipment of materials (such as coal, ore, grain, etc.). [0003] Domestic coal-fired power plants have a very serious phenomenon of coal loss per ton and card loss...
