Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-4 The utility model provides a technical solution: a stone analysis pressing device, including a mold 1, the mold 1 is cylindrical, the end surface of the mold 1 is penetrated by a circular through groove 2, the circular through groove 2 is coaxially arranged with the mold 1, the upper surface of the mold 1 is conical, which is convenient for putting in stone powder, the bottom of the mold 1 is provided with a lower mold 3, the upper end of the mold 1 is provided with an upper mold 4, the lower mold 3 and the upper mold 4 are both cylindrical plate-like structures, the upper surface of the lower mold 3 corresponds to the inner part of the circular through groove 2 and is fixedly connected with a top block 5, and the lower surface of the upper mold 4 corresponds to the circular through groove 2 and is fixedly connected with a pressing block 6, such as Figure 2 As shown, the lower surface of the pressing block 6 is conical, and the top block 5 and the pressing block 6 are both located inside the circular through groove 2. The powder is placed inside the circular through groove 2 and pressed by a tablet press. The powder can be pressed into a sheet structure under the action of the top block 5 and the pressing block 6 and fixed inside the mold 1, and then the pressed specimen can be analyzed.

[0018] Specifically, a tablet press is also included, and the tablet press includes a base 7, such as Figure 4 As shown, the base 7 is cylindrical, and a turntable 8 is rotatably provided on the upper surface of the base 7. The mold 1 is installed at the edge of the end surface of the turntable 8. A movable rod 9 is provided on the upper surface of the base 7. There are two movable rods 9, one of which is coaxially arranged with the turntable 8, and the other movable rod 9 is located on the upper surface of the base 7 and corresponds to the edge of the turntable 8. A movable plate 10 is fixedly connected to the top of the movable rod 9. The movable plate 10 is arranged horizontally, and the end surface of the movable plate 10 is penetrated and screwed with a screw 11. A hydraulic mechanism for driving the movable rod 9 to move is provided inside the base 7. The hydraulic mechanism is used to control the movable rod 9 to move downward, drive the movable plate 10, and thus drive the screw 11 to move downward. By rotating the turntable 8, the mold 1 is moved to the bottom end of the screw 11, and then the screw 11 is controlled to be pressed downward to press the mold. After the pressing is completed, the turntable 8 can be rotated to move the next mold to the bottom of the screw 11, so that continuous pressing can be performed.

[0019] Specifically, a through slot 12 is provided through the end surface of the turntable 8, and the through slot 12 is circular. The inner surface of the through slot 12 is movably provided with a movable ring 13, such as Figure 3As shown, the end face of the movable ring 13 is penetrated with a limiting groove 14 for the mold 1 to pass through, and the lower end of the inner circumference of the limiting groove 14 is fixedly connected with a limiting ring 15. The mold 1 is placed inside the limiting groove 14. Under the action of the limiting ring 15, the mold 1 will not fall, so that the mold 1 can rotate with the rotation of the turntable 8.

[0020] Specifically, the inner circumference of the through groove 12 is coaxially provided with an annular groove 16, and the outer circumference of the movable ring 13 is fixedly connected with an annular block 17 corresponding to the annular groove 16. An elastic element is provided between the annular block 17 and the annular groove 16. The elastic element can be a spring. Under the action of the elastic element, the movable ring 13 is located in the through groove 12 and has a tendency to move upward. When the mold 1 is placed on the movable ring 13, there is a certain distance between the bottom of the mold 1 and the base 7, so that the turntable 8 can rotate freely. Figure 3 As shown, a fixed block can be set on the upper surface of the base 1 corresponding to the bottom of the screw 11. When the screw 11 is controlled to move downward, the screw 11 contacts the upper mold 4 and moves downward. Under this pressure, the movable ring 13 overcomes the elastic element and moves downward, so that the lower mold 3 contacts the fixed block, and then the screw 11 continues to move to press the specimen.

[0021] When the utility model is used, the mold 1, the upper mold 4 and the lower mold 3 are assembled, and the mold 1 is placed in the limiting groove 14 in sequence. After adjusting the position of the screw 11, the turntable 8 is rotated to move the mold 1 to the bottom of the screw 11, and the movable rod 9 drives the movable plate 10 to move downward by starting the hydraulic mechanism. The movable rod 9 moves downward through the screw 11, and the mold is pressed by the screw 11. After the pressing is completed, the mold 1 is removed, and the turntable 8 can continue to be rotated to move the new mold 1 to the bottom of the screw 11 to achieve continuous pressing.
