Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mineral raw material sampling, and particularly relates to a reduction sampler. Background Art
[0002] Mineral raw material sampling involves dividing the flat test material into equal parts using a flat plate or other tool. Common sampling methods include quartering and eighthing. The quartering method divides the test material into four equal parts, then tests two opposite parts; the eighth method divides the test material into eight equal parts, then tests two opposite parts.
[0003] Sampling by subtraction determines the accuracy of test results to a certain extent. Existing methods mostly use two partitions to manually divide the test material into four or eight equal parts, and then use the partitions to scoop out two opposite parts of the test material. This manual sampling method cannot guarantee equal division and can result in significant errors, especially when dividing the material into eight equal parts, where it is difficult to ensure that the material is evenly divided. Utility Model Content

[0007] Furthermore, the first rotating connection assembly includes two first sleeves fixedly arranged at the upper and lower ends of the side surface of the first sampling plate, and a first rotating shaft fixedly arranged on the side surface of the second sampling plate and movably inserted into the upper and lower first sleeves at both ends; the first limiting assembly includes a first limiting ring circumferentially arranged on the outer wall of the insertion end of the first rotating shaft and a first elastic limiting rod radially fixedly arranged at a corresponding position on the inner wall of the first sleeve, the first elastic limiting rod includes a first limiting button with a hemispherical round head at the outer end and a first spring fixedly connected to the inner end of the first limiting button and the inner wall of the first sleeve at both ends, a first limiting hole and a second limiting hole are radially opened in the first limiting ring, and the shapes of the two limiting holes are adapted to the round heads; the first elastic limiting rod can slide in the first limiting ring and is in a compressed state, and when the first elastic limiting rod slides in the first limiting ring, the round head at the outer end of the first limiting rod can slide in and out of the two limiting holes, and when sliding into the two limiting holes, the angle between the first sampling plate and the second sampling plate is limited to 90° and 45°, respectively.
[0008] Furthermore, the second rotating connection assembly includes two second shaft sleeves fixedly arranged at the upper and lower ends of the side surface of the third sampling plate, and a second rotating shaft fixedly arranged on the side surface of the fourth sampling plate and movably inserted into the upper and lower second shaft sleeves at both ends; the second limiting assembly includes a second limiting ring circumferentially arranged on the outer wall of the insertion end of the second rotating shaft and a second elastic limiting rod radially fixedly arranged at a corresponding position on the inner wall of the second shaft sleeve, the elastic limiting rod includes a second limiting button with a hemispherical round head at the outer end and a second spring with two ends fixedly connected to the inner end of the second limiting button and the inner wall of the second shaft sleeve, a third limiting hole and a fourth limiting hole are radially opened in the second limiting ring, and the shapes of the two limiting holes are adapted to the round heads; the second elastic limiting rod can slide in the second limiting ring and is in a compressed state. When the second elastic limiting rod slides in the second limiting ring, the round head at its outer end can slide in and out of the two limiting holes, and when it slides into the two limiting holes, the angles between the third sampling plate and the fourth sampling plate are limited to 90° and 45°, respectively.
[0009] Furthermore, the keyway assembly includes a first limiting groove and a second limiting groove, both of which are axially opened on the outer wall of the first sleeve, and a first limiting plate and a second limiting plate, both of which are axially fixed on the outer wall of the second sleeve, and the shapes of the first limiting groove and the second limiting groove are respectively adapted to the shapes of the first limiting plate and the second limiting plate; when the angle between the first sampling plate and the second sampling plate and the angle between the third sampling plate and the fourth sampling plate are both 90° or 45°, the first limiting plate and the second limiting plate are respectively inserted into the first limiting groove and the second limiting groove, and at this time, the angle between the first sampling plate and the fourth sampling plate and the angle between the second sampling plate and the third sampling plate are respectively 90° and 135°.
[0010] The beneficial effects of the utility model are:
[0011] The first sampling mechanism and the second sampling mechanism of the utility model are detachably connected. Before sample separation, the angle between the two sampling plates of the two sampling mechanisms is first adjusted. When sample separation is performed, the first sampling mechanism and the second sampling mechanism are connected together. When sampling, it is only necessary to pull the first sampling mechanism and the second sampling mechanism at the same time to separate the two sampling mechanisms, thereby realizing convenient and efficient sample separation.
[0012] The two limit assemblies can keep the angle between the first sampling plate and the second sampling plate, and the angle between the third sampling plate and the fourth sampling plate at 45° or 90°. By setting the limit assemblies, the angles of the first sampling mechanism and the second sampling mechanism can be quickly adjusted, thereby quickly dividing the test material into four or eight equal parts.

[0024] The first rotating connection assembly includes two first sleeves 5 fixedly arranged at the upper and lower ends of the side surface of the first sampling plate 3 and a first rotating shaft 9 fixedly arranged on the side surface of the second sampling plate 4 and movably inserted in the upper and lower first sleeves 5 at both ends; the first limiting assembly includes a first limiting ring circumferentially arranged on the outer wall of the insertion end of the first rotating shaft 9 and a first elastic limiting rod 8 radially fixedly arranged at a corresponding position on the inner wall of the first sleeve 5, the first elastic limiting rod 8 includes a first limiting button 82 with a hemispherical round head at the outer end and a first spring 81 fixedly connected to the inner end of the first limiting button 82 and the inner wall of the first sleeve 5 at both ends, a first limiting hole 10 and a second limiting hole 11 are radially opened in the first limiting ring, and the shapes of the two limiting holes are adapted to the round heads; the first elastic limiting rod 8 can slide in the first limiting ring and is in a compressed state. When the first elastic limiting rod 8 slides in the first limiting ring, the round head at its outer end can slide in and out of the two limiting holes.
[0025] When the first limiting button 82 slides into the first limiting hole 10, the angle between the first sampling plate 3 and the second sampling plate 4 is 90°. When the first limiting button 82 slides into the second limiting hole 11, the angle between the first sampling plate 3 and the second sampling plate 4 is 45°.
[0026] The second rotating connection assembly has a substantially similar structure to the first rotating connection assembly.

[0030] Place the center point of the installed reduction sampler above the center point of the test material, and press the reduction sampler downward until the reduction sampler completely separates the test material; then pull the first sampling mechanism 1 and the second sampling mechanism 2 in opposite directions to separate the two sampling mechanisms until the material is completely taken out. This method of use can divide the test material into four equal parts.
[0031] As another method of use, the first limit button 82 corresponding to the second sampling plate 4 and the second limit button corresponding to the fourth sampling plate 13 are respectively rotated to the corresponding second limit hole 11 and fourth limit hole. At this time, the two sampling plates of the first sampling mechanism 1 and the second sampling mechanism 2 are at a 45° angle; then the second limit plate 16 of the second sampling mechanism 2 is inserted into the second limit groove 7 of the first sampling mechanism 1, and the installation of the reduction sampler is completed.
