Description

Technical Field

[0001] The invention belongs to the technical field of geological sample sampling devices, in particular to a sample sampling device for geological exploration. Background Art

[0002] Geological and mineral exploration is based on a large amount of field geological observations and the collection and collation of relevant geological data, using comprehensive geological means and methods such as geological surveys and drilling projects. In the process of geological and mineral exploration, it is necessary to analyze the exploration samples. When analyzing the samples, the samples need to be broken. The broken samples are easy to carry, so that their characteristics can be analyzed using analytical equipment. The initial geological exploration crushing method is generally just the exploration personnel using hammers to break them. This crushing method is not only time-consuming, the crushed particles are large, the work intensity is high, and the flying of gravel has certain safety hazards.

[0003] To avoid the above problems, surveyors began to use crushers for crushing and sampling. Existing crushers generally break samples into several small pieces by applying external force to the samples or causing collisions between samples or between samples and external equipment such as impact plates. The current crushing devices mainly have the following problems: after the samples are crushed, it is difficult to break them into small pieces of specified specifications at one time, and if the samples are to be crushed at one time, the feeding speed must be slowed down, otherwise the sample fragments that fail to pass through the screen will accumulate at the screen, or even clog, causing the entire crusher to be unable to work continuously. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a sample sampling device for geological exploration, which can avoid sample accumulation in a centrifugal cylinder, effectively improve the sample crushing speed, and avoid clogging at the drop net due to insufficient sample crushing particle size through cyclic crushing.

[0005] In order to solve the above technical problems, the present invention is solved by the following technical solutions: a sample sampling device for geological exploration, comprising a centrifugal cylinder, an intermediate cylinder and an outer cylinder arranged concentrically from the inside to the outside, the bottom of the intermediate cylinder and the outer cylinder are provided with a material drop net, one side of the outer cylinder is provided with a feeding port connected to the centrifugal cylinder, the other side of the outer cylinder is rotatably provided with a turntable, the centrifugal cylinder is rotatably arranged in the intermediate cylinder, the inner and outer side walls of the centrifugal cylinder are provided with crushing blocks, the side wall of the centrifugal cylinder is provided with a material passing hole, the first annular channel between the centrifugal cylinder and the intermediate cylinder is provided with a crushing shaft on the turntable rotatably arranged, the A gear is provided at the outer end of the crushing shaft, and a gear ring meshing with the gear is provided on the outer cylinder. The crushing shaft rotates in the opposite direction to the centrifugal cylinder so as to clamp and crush the sample in the gap between the two. A filter plate fixed on the turntable is provided in the second annular channel between the intermediate cylinder and the outer cylinder, and a drop-out port is provided on the side wall of the intermediate cylinder. A rotating plate is provided on the drop-out port by a torsion spring, and an elastic push rod is provided on the side of the filter plate. An arc-shaped push block is provided on the outer cylinder opposite to the rotating plate. When the elastic push rod passes through the arc-shaped push block, the rotating plate is pressed down by the arc-shaped push block to open the drop-out port. The sample sampling device for geological exploration puts samples into the sample through the feed port. After the sample is initially crushed by the centrifugal cylinder, it can quickly pass through the material hole into the first annular channel. A part of the sample that has met the discharge requirements will be discharged directly through the drop nets on the intermediate cylinder and the outer cylinder. The sample with particles larger than the mesh of the drop net on the intermediate cylinder remains at the bottom of the first annular channel, and the sample with particles larger than the mesh of the drop net on the outer cylinder remains at the bottom of the second annular channel.

At the same time, the filter plate rotates to lift and move the sample at the bottom of the second annular channel and when it rotates to the arc top block position, it pushes the rotating plate open to make it fall into the first annular channel. The crushing shaft cooperates with the outer wall of the centrifugal cylinder to continue to crush.
