Description

Technical Field

[0001] The utility model belongs to the technical field of filling body sample cutting devices, in particular to a mine filling body sample core cutting device. Background Art

[0002] At present, when the first-step mining of the mine is nearing the end, considering that after the first-step stope is mined, the second-step stope is in a state of greater stress concentration after stress redistribution, the unstable surrounding rock and some filling bodies with low compressive strength may experience ground pressure under greater stress concentration. Therefore, whether the second-step stope surrounded by the filling body and in stress concentration can be mined safely is directly related to the connection of mine production capacity. Since the first-step stope uses tailings cementation filling, the mining of the second-step stope will face the current situation of filling bodies on both sides and some mining projects arranged in the filling body. Due to the low strength of the filling body, the filling body needs to be sampled and tested before the second-step stope is mined, its strength and integrity need to be analyzed, and the filling body boundary needs to be detected by drilling and coring, and the filling body boundary map needs to be drawn to provide basic data for subsequent mining plan selection and stope stability calculation.

[0003] The filling body sample core is generally cylindrical, but because it is taken out by a core drill, the two ends of the sample core are generally not flat. Before testing, the sample core needs to be cut into a suitable length, and the two ends need to be kept flat; the existing cutting method is to first cut a part of the two ends of the sample core to keep the two ends flat, then measure the required length of the sample from one end as the starting point and mark it, and then cut from the mark to obtain the filling body sample; this method is more troublesome and affects the test progress.

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments.

[0026] Example

[0027] like Figure 1 As shown;

[0028] The mine filling body sample core cutting device comprises a processing table 1; a mounting plate 2, the mounting plate 2 is fixed on the processing table 1, and a guide rod 21 is horizontally mounted on the mounting plate 2; a main cutter 3 is rotatably mounted in the middle of the guide rod 21, wherein the two sides of the rotating part of the main cutter 3 are restricted by two bolts, so that the main cutter 3 can only rotate and cannot move on the guide rod 21; in addition, rotatable auxiliary cutters 4 are symmetrically mounted on the guide rod 21 on both sides of the main cutter 3, and the auxiliary cutter 4 can also slide on the guide rod 21 to adjust the position;

[0029] When in use, adjust the distance between one of the auxiliary cutters 4 and the main cutter 3 so that the distance is equal to the length of the sample core that needs to be cut, then adjust the other auxiliary cutter 4, and then place the sample core on the processing table 1 so that its two ends are located on the outside of the two auxiliary cutters 4, and finally start and rotate the main cutter 3 and the auxiliary cutter 4, so that the three can cut three different positions on the sample core, which are the uneven parts at both ends of the sample core, and then the filling body sample is cut. This cutting method improves the cutting efficiency, speeds up the test progress, and can also cut the sample core according to different length requirements, thereby improving practicality.

[0030] like Figure 2-4 As shown;

[0031] A positioning member 7 is provided on one side of the auxiliary cutting machine 4, and a positioning hole 1 22 and a positioning hole 23 are evenly opened on the mounting plate 2 at positions corresponding to the auxiliary cutting machine 4, wherein the positioning member 7 comprises a vertical rod 71, the vertical rod 71 matches the positioning hole 1 22, a horizontal rod 72 is fixed on one side of the vertical rod 71, the horizontal rod 72 matches the positioning hole 23, and the vertical rod 71 is inserted into the positioning hole 1 22, and the horizontal rod 72 is inserted into the positioning hole 23, so that the auxiliary cutting machine 4 can be fixed after the position is adjusted, thereby improving the stability of the auxiliary cutting machine 4 when cutting at the back, and a reinforcing rod 73 is fixed between the vertical rod 71 and the horizontal rod 72, and the reinforcing rod 73 improves the stability of the vertical rod 71 and the horizontal rod 72, thereby further improving the stability of the auxiliary cutting machine 4 when cutting at the back;

[0032] Furthermore, a rotation groove 41 is provided in an annular manner on the outer side of the rotation connection of the housing of the auxiliary cutting machine 4, and a rotating member 9 is movably installed in the rotation groove 41. The rotating member 9 is provided with an insertion hole, and the vertical rod 71 can pass through the insertion hole. The vertical rod 71 first passes through the insertion hole and then is inserted into the positioning hole 22. In this way, the auxiliary cutting machine 4 can be limited by the positioning member 7 and the rotating member 9 to prevent it from moving or shaking after the position is adjusted, thereby affecting the subsequent cutting effect, and the limit position can be fixed without affecting the rotation of the auxiliary cutting machine 4;

[0033] Furthermore, a uniform scale line 24 is provided on the mounting plate 2 corresponding to the portion between the auxiliary cutting machine 4 and the main cutting machine 3. The scale line 24 facilitates the movement of the auxiliary cutting machine 4 to a suitable position, so that the distance between the auxiliary cutting machine 4 and the main cutting machine 3 is equal to the length of the sample core that needs to be cut, thereby improving the cutting accuracy.

[0034] like Figure 1 As shown;

[0035] A placing table 5 is provided on the processing table 1. The top of the placing table 5 is arc-shaped, which is convenient for placing the sample core and improving the stability of the sample core. A clamping plate 6 is evenly hingedly installed on the rear side of the placing table 5 corresponding to the processing table 1. A telescopic member 61 is hingedly installed on the outer side of the clamping plate 6. The telescopic member 61 can be a cylinder. The other end of the telescopic member 61 is hinged on the mounting plate 2. When in use, the sample core is placed on the placing table 5, and then the telescopic member 61 is started to extend, so that the clamping plate 6 rotates to cover the sample core and clamps the sample core, so that the sample core is more stable when being cut, and the cutting accuracy and the effect after cutting are improved;

[0036] Furthermore, a through groove 11 is opened on the processing table 1 and the placement table 5 corresponding to the downward projection of the main cutting machine 3, and a through hole 12 is opened on the processing table 1 corresponding to the position of the lower extension line of the auxiliary cutting machine 4. The through groove 11 and the through hole 12 facilitate the passage of the blades on the main cutting machine 3 and the auxiliary cutting machine 4, so that the sample core cutting position can be completely cut off, and at the same time, the uneven part of the sample core cut off by the auxiliary cutting machine 4 can also be discharged from the through hole 12.

[0037] like Figure 2 As shown;

[0038] A pull rod 8 is provided on the outer shell of the main cutting machine 3 and the auxiliary cutting machine 4. When the pull rod 8 is manually pulled, the main cutting machine 3 or the auxiliary cutting machine 4 rotates. A series hole is provided on the pull rod 8, and a series rod 81 can be inserted into the series hole. The two auxiliary cutting machines 4 and the main cutting machine 3 can be connected in series through the series rod 81, that is, only one pull rod 8 needs to be pulled to rotate the two auxiliary cutting machines 4 and the main cutting machine 3, so that they can cut synchronously and improve the cutting effect. At the same time, after removing the series rod 81, the two auxiliary cutting machines 4 and the main cutting machine 3 can be rotated separately for cutting, and the cutting method can be changed according to the actual situation to improve practicality.

[0039] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
