Description
Technical Field
The utility model belongs to the field of loose ore sampling, and particularly relates to a loose ore grid method sampling device.
Background
The open-pit mine stope blasting sampling, the outsourcing ore sampling and production grade control of smelting and processing enterprises, the ore sampling at the import and export of trade companies and the like all relate to the ore sampling problem under the natural loose condition. The traditional method mainly adopts manual random sampling or grid sampling. The sampling position of the manual random sampling is mainly judged by the subjective of practitioners, the sampling representativeness is relatively poor, and the manual random sampling is suitable for sampling with low precision requirement. The traditional grid method sampling generally adopts a measuring tool with a fixed length to measure and obtain a grid, and samples are carried out at the intersection point or the center point of the grid, or a prefabricated net-shaped tool is laid, and samples are carried out at the approximate center position of each square of the net-shaped tool. Compared with the two methods, the latter method avoids subjective interference of a part of practitioners, improves sample objectivity, but has complex configuration of a measuring tool or a net-shaped tool and needs to invest more resources. In addition, if the mesh tool has a larger square mesh size, the center position is often more difficult to determine and there is still a higher randomness. Therefore, the sampling mode of loose ore in natural state is difficult to satisfy the requirements of objectivity, accuracy, low cost, convenience and rapidness in sampling loose ore.
SUMMERY OF THE UTILITY MODEL
In view of the above-mentioned deficiencies of the prior art, the present invention provides an improved sampling device for loose ore by grid method.
The utility model is realized by the following technical scheme.
A loose ore grid method sampling device comprises a main rope and a knot; the main rope is made of hemp ropes or nylon ropes, the diameter of the main rope is 10mm-15mm, and a plurality of knots are uniformly distributed on the main rope.
Further, the interval between the knots is 500-1000 mm.
Further, the knot is generated by the main rope knot or is a mark made on the main rope. For example, the main rope may be tied with other materials such as commercially available plastic rope and waste cloth, and has a certain degree of identification.
Wherein, the main rope is made of wear-resistant and light materials, and flexible materials such as hemp ropes, nylon ropes and the like are generally used.
The utility model has the beneficial technical effects that:
1. the utility model discloses a configuration is simple, need not to drop into more resource, and the material acquires easily, and the low price, almost need not the maintenance, and the facilitate promotion is implemented.
2. When the device is used, the sampling position is controlled by the knot on the main rope, and the sampling position is relatively fixed, so that the subjective interference of practitioners is avoided.
3. The device preparation is very simple, only need according to fixed interval with main rope knot or mark on the rope can, can be according to the sample needs moreover, the knot of various intervals of very convenient demarcation.
4. The device is portable, and 1-2 people can carry the device to a use place. And the use principle is simple and is easy to master by practitioners.
5. The device can satisfy loose ore sample objectivity and accuracy needs.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the sampling device of the present invention comprises a main string and a knot; the main rope is made of hemp ropes or nylon ropes, the diameter of the main rope is 10mm-15mm, and a plurality of knots are uniformly distributed on the main rope. The working principle of the sampling device is as follows: the whole main rope is arranged on three sides of the loose ore heap, such as the sides a, b and c. a. The main rope of the c surface keeps a certain distance with the boundary of the loose ore heap, and the main rope of the b surface is temporarily arranged at the edge of the loose ore heap. After the arrangement is finished, the main rope on the b surface is sampled, and the sampling point position is overlapped with the knot position. And after the first row of b-surface main ropes are completely sampled, moving the b-surface main ropes, controlling the moving distance from the b surface to the d surface by knots arranged on the a-surface main ropes and the c-surface main ropes, wherein the moving distance is the same as the sampling interval of the first row. And then, sampling in a second row, wherein the sampling point position is overlapped with the knot position on the main rope, and the sampling interval is consistent with that in the first row. And moving the b-surface main rope for a plurality of times in sequence, completing the sampling corresponding to each row, and finally completing the sampling of the whole loose ore heap. In the process, the main ropes on the surfaces a and c are always kept still, and the main rope on the surface b only needs to be moved each time until the main rope moves to the surface d of the loose ore pile.
The sampling is carried out by adopting a manual sampling mode, a shovel, a sampling shovel, a self-made shovel and the like are usually used as sampling tools, and the materials are preferably wear-resistant and hard; the spade head is a pointed end, is convenient for cutting into loose ore heap, and the spade head specification is 150 × 200mm, can take wooden long handle convenient to use. The sampling depth of each point is generally 150-; the spreading thickness of the loose ore is not too thick generally, preferably 300-400mm, and the loose ore is uniformly mixed by using a mechanical method and the like before spreading; the weight of each sample can be determined by comprehensively considering different particle size grade distributions and the like; all sample point samples can be combined into a comprehensive sample or a plurality of samples, and are determined according to needs.
In addition, the distance of each movement of the main rope can be 1 knot distance, and also can be a plurality of knot distances, as long as the distance of the movement is consistent with the sampling distance of each row, and finally a square grid type sampling point set is formed.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model. It should be noted that other equivalent modifications can be made by those skilled in the art in light of the teachings of the present invention, and all such modifications can be made as are within the scope of the present invention.
