Description

Technical Field

[0001] The utility model relates to an open-pit mine blasting dust sampler, belonging to the technical field of open-pit mine sampling equipment. Background Art

[0002] Sampling of blasting dust in open-pit mines is an important part of mining sampling work and is a low-cost method for grade control. The traditional method of collecting blasting dust samples is mainly for the sampler to use a sample shovel to sample at a suitable position on the blasting dust pile. This method may not be able to collect all the vertical integrity of the blasting dust pile, especially the rock dust chips at the bottom are often not available; due to climatic reasons, in the dry season, the blasting dust pile is loose and dry, and it is easy to slide during sampling. In the rainy season, the blasting dust pile is wet and compacted, and the sample is easy to stick to the sampling tool; resulting in a large deviation in the sampling results, and this sampling method is greatly affected by the operator's experience and attitude. The double-action double-tube sampling device has two layers of inner and outer core tubes. Because it has an inner tube to protect the sample, it is not affected by rain, and can take out samples of soft, loose, and broken rock layers. It can meet the sampling requirements and is relatively convenient, but the equipment is complex and the production cost is high. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the problem to be solved by the utility model is: to provide a structure with reasonable design, easy use, low cost, high reliability, which can sample from the top to the bottom of the gun powder pile and seal it, and can easily push the sample into the sampling bag, thereby solving the problems existing in the background technology.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A blasting powder sampler for an open-pit mine comprises an outer cylinder, a handle one, a sampling cylinder, a handle two, a spring, a pipe opening blade, a piston and a sealing piece. The outer cylinder is connected to the handle one through a round tube, and the sampling cylinder and the handle two are also connected through a round tube. The round tube connected to the sampling cylinder is sleeved in the round tube connected to the outer cylinder, the pipe opening blade is installed at the bottom of the sampling cylinder, a spring is connected between the top of the outer cylinder and the inner cylinder, a piston is placed in the sampling cylinder, a piston body at the lower end of the piston is located at the bottom of the sampling cylinder, a handle at the upper end of the piston passes through the upper end of the round tube connected to the sampling cylinder, a scale is provided at the handle adjacent to the upper end of the piston, and a sealer is at the bottom of the outer cylinder.

[0006] The handle of the piston is connected to the piston body at the lower end of the piston by a long bolt, and there is a scale on the long bolt.

[0007] The round tube connected to the sampling cylinder and the second handle are connected via threads.

[0008] The bottom of the sampling circular tube is threadedly connected to the pipe opening cutting foot.

[0009] The sealer is a reed structure.

[0010] When taking samples using the utility model, the second handle is pressed toward the first handle, the bottom of the sampling cylinder is extended from the reed of the sealer, and the bottom of the sampler is inserted into the open-pit mine blasting powder pile. As the force is applied downward, the piston is pushed upward by the rock powder that has entered the sampling cylinder. The sampling depth is determined according to the scale on the long bolt, and then the second handle is released. The sampling cylinder rebounds under the action of elastic force. When the sealer is closed, the blasting powder sample is taken out.

[0011] The utility model has the following beneficial effects: when sampling, the artificial disturbance to the rock cuttings is small, the influence by the outside world is small, the sampling is accurate and can adapt to arid or humid environments, the burial depth of the sample in the blasting powder pile can be judged, and the sampling is fast.
