Abstract
The utility model relates to a magnetite core grade estimation device and belongs to the technical field of geological exploration. The magnetite core grade estimation device is composed of a three-surface number displaying dial (2), an indicator (5) arranged on the three-surface number displaying dial (2), a linear spring (6) arranged in the three-surface number displaying dial (2), a lifting handle (1), a connecting rod (4) and a fixed magnet (3), wherein the lifting handle (1) and the connecting rod (4) are respectively connected with the linear spring (6), and the connecting rod is connected with the fixed magnet (3). The magnetite core grade estimation device has the advantages of being simple in structure, easy to assemble and convenient to use. Compared with ocular estimation, estimation accuracy is improved, and geological record work quality is improved.
Description
Technical field:
The utility model relates to a kind of MAG core grade estimating apparatus, matter exploration engineering field, possession.
Background technology:
In the mining area that is the master, when geological personnel is edited and recorded boring, all be to lean on visual estimation and estimate the MAG grade by methods such as magnet sensations with the MAG with hand; And then carry out petrographic description and stratigraphic division and instruct whole hole site; These method deviations are big, cause the accuracy of petrographic description and stratigraphic division and whole hole site low, also later cloth specimen and sample examination work impacted simultaneously; Make the termination of ore body produce deviation, increased the original workload of editing and recording modification.
Summary of the invention:
The purpose of the utility model is to overcome the deficiency of prior art, and provides a kind of simple in structure, and is easy to use, the MAG core grade estimating apparatus that is easy to safeguard.
The MAG core grade estimating apparatus of the utility model, by three registration index dials 2, place three on the registration index dial 2 pointer 5, place linear elastic spring 6, the handle 1 that is connected with linear elastic spring 6 respectively and the connecting link 4 in three registration index dials 2, the fixed magnet 3 that is connected with connecting link 4 to form.
The MAG core grade estimating apparatus of the utility model, the material that adopts market to buy prepares by conventional method.
The principle of work of the utility model is:
Magnet to the attractive force of MAG core along with the increase of the rising of grade and core diameter and increase; Under the situation promptly certain at magnet magnetic force, that core diameter is certain, the height of MAG core grade is directly proportional with the attractive force of magnet to the MAG core.Under different core diameters, grade height and gravitation size are set up the corresponding relation in this mining area through test, obtain three registration index dials, promptly a scale is represented the registration that concerns under a kind of core diameter.
Totally 27 groups of the cores of existing result of laboratory test of collection and different grade different-diameters, every group is no less than 3 samples.27 groups of samples are tested and record.Ask for grade mean value and registration mean place for every group.Because the sample that is extracted chemical examination grade only is near the integer grade, rather than equals the integer grade, so the geometric ratio method of application of known is tried to achieve integer grade spring balance registration.Average grade like one group of similar core is 30.29%, and average registration position is 20cm, and trying to achieve grade by 30.29%/20=30%/x so is 30% registration mean place.On index dial with integer grade registration position mark to above as new scale, in this process, to make the different graduated scale of multiaspect according to multiple different core diameter.
After accomplishing above-mentioned work, can be applied in the actual work.Device is placed on the core that will test, and the core diameter size should be corresponding with corresponding index dial, and the pulling handle leaves the moment of MAG core and reads numerical value at magnet, promptly be the estimation grade of this section MAG core.
The advantage of the utility model is:
1, simple in structure, be easy to assembling, easy to use.
2, compare with visual estimation, improved the estimation precision, promoted the geological record work quality.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
The MAG core grade estimating apparatus of the utility model, by three registration index dials 2, place three on the registration index dial 2 pointer 5, place linear elastic spring 6, the handle 1 that is connected with linear elastic spring 6 respectively and the connecting link 4 in three registration index dials 2, the fixed magnet 3 that is connected with connecting link 4 to form.
The MAG core grade estimating apparatus of the utility model, the material that adopts market to buy prepares by conventional method.
The course of work is:
(1) in new workspace, experimentizing through existing grade core obtains grade scale value (the summary of the invention part has been done detailed description).
(2) device is placed on the core that will test, this moment is corresponding with corresponding index dial 2 with core diameter, leaves the moment of MAG core at magnet and reads numerical value, and this numerical value promptly is the estimation grade of this section MAG core.
Facts have proved that the utility model reaches designing requirement fully.
Claims (1)
1. MAG core grade estimating apparatus, it is characterized in that this device by three registration index dials (2), place pointer (5) on three registration index dials (2), place linear elastic spring (6), the handle (1) that is connected with linear elastic spring (6) respectively and the connecting link (4) in three registration index dials (2), the fixed magnet (3) that is connected with connecting link (4) to form.
