[0028] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Such as Figures 1 to 5As shown in the figure, a sample preparation machine in an embodiment of the present utility model includes a conveying device 1. The conveying device 1 is a conveyor belt used for conveying coal and is used to convey coal. A bracket 2 is fixedly connected to the conveying device 1, and a rotating cylinder 6 is rotatably installed through the bracket 2. The rotating cylinder 6 can rotate on the bracket 2.

[0030] As Figure 1 and Figure 2 shown in the figure, a motor 5 is installed on the bracket 2. The output end of the motor 5 is fixedly connected to the driving end of the rotating cylinder 6. By using the power provided by the motor 5, the rotating cylinder 6 can be driven to rotate.

[0031] As Figure 3 and Figure 5 shown in the figure, an installation opening 12 is provided on the rotating cylinder 6. The inner wall of the installation opening 12 is fixedly connected with a collection box 13. One end of the collection box 13 extends into the interior of the rotating cylinder 6 and is provided with a discharge opening 14. There are two discharge openings 14, which can improve the discharge effect. And the other end extends to the outside of the rotating cylinder 6 and is provided with a feed opening 15. The collection box 13 can rotate with the rotating cylinder 6. When the collection box 13 rotates to the position closest to the conveyor belt, it can contact the coal conveyed on the conveyor belt, and the coal can enter the interior of the collection box 13 through the feed opening 15 during the conveying process.

[0032] As Figure 5 shown in the figure, generally, the thickness of the coal seam conveyed by the conveyor belt is 20 cm to 30 cm, and the distance between the collection box 13 and the conveyor belt is 10 cm to 20 cm. When the collection box 13 is at the shortest distance from the conveyor belt, it can be inserted into the conveyed coal seam, so that the coal can enter the collection box 13 through the feed opening 15. One end of the collection box 13 away from the rotating cylinder 6 is arc-shaped. The arc shape at the bottom of the collection box 13 can reduce the impact on the collection box 13 caused by the conveyed coal, which is beneficial to improving its service life.

[0033] As Figure 5 shown in the figure, a first baffle 16 is movably installed inside the feed opening 15. One side of the first baffle 16 is fixedly connected with multiple groups of springs 17. One end of each group of springs 17 away from the baffle is fixedly connected to the inner wall of the collection box 13. When the coal contacts the first baffle 16 at the feed opening 15, the kinetic energy of the conveyed coal can push the first baffle 16 to open the feed opening 15, and the coal enters the interior of the collection box 13 through the feed opening 15. A second baffle 18 is movably installed inside the collection box 13. The second baffle 18 can separate the discharge opening 14 to form a coal storage space inside the collection box 13 for quantitatively collecting coal.

[0034] As Figure 5As shown, the first baffle 16 closes the feed port 15, and the second baffle 18 separates the discharge port 14, and cooperates with the collection box 13 to form a closed chamber. After the collected coal enters the collection box 13 through the feed port 15, it can be stored in the closed chamber formed inside it. When the drum 6 continues to rotate, the second baffle 18 can move under the action of gravity to open the discharge port 14. At this time, the coal in the collection box 13 can fall into the drum 6 through the discharge port 14.

[0035] As Figure 5 As shown, two slide bars 20 are fixedly connected to the inner wall of the collection box 13, and two grooves 19 matching the slide bars 20 are opened on the surface of the second baffle 18, so that the second baffle 18 can move along the slide bars 20, which can limit the second baffle 18 and make its movement more stable and smooth, preventing it from falling.

[0036] like Figure 5 As shown, the lower surface of the second baffle 18 has a slope, and the setting of the slope enables the coal to fall out better and faster, and avoids the coal remaining on the second baffle 18 after it is rotated to a horizontal position.

[0037] like Figure 4 As shown, the inner wall of the rotating drum 6 is rotatably connected to multiple groups of mixing rods 11, and the mixing rods 11 are respectively arranged on both sides of the collecting box 13 in the rotating drum 6. During the rotation of the rotating drum 6, the coal will move inside it and collide with the mixing rods 11 to achieve coal crushing and mixing.

[0038] like Figure 3 and Figure 4 As shown, an output port 7 is provided on the surface of the rotating drum 6, and the output port 7 is arranged in the middle position of the surface of the rotating drum 6 and on the side away from the installation port 12. An output pipe 8 is fixedly connected to the inner wall of the output port 7, and the output end of the output pipe 8 extends to the outside of the rotating drum 6. The output port 7 and the output pipe 8 can be used to output the coal in the rotating drum 6 for use. A control valve 9 is installed on the output pipe 8, and the control valve 9 can control the opening and closing of the output pipe 8 to facilitate the material taking operation.

[0039] like Figure 4 As shown, the inner wall of the rotating drum 6 is fixedly connected with a guide plate 10, and the guide plate 10 is arranged on both sides of the discharge port 14. The guide plate 10 can guide the coal sample inside the rotating drum 6, so that it can be better discharged outward through the discharge port 14 and the output pipe 8, thereby preventing coal from remaining in the rotating drum 6.

[0040] like Figure 1 and Figure 2As shown, a through opening 3 is provided on the surface of the support bracket 2. A support plate 4 is fixedly connected to the surface of the support bracket 2. The support plate 4 is located below the rotating cylinder 6 and is horizontal with the through opening 3. The through opening 3 facilitates the taking of the material output through the output pipeline 8. The support plate 4 can support the material taking device in use, making it more labor-saving and convenient.

[0041] During use, the conveyor belt conveys coal. The rotating cylinder 6 is controlled to rotate so that the collection box 13 moves to the position closest to the conveyor belt. At this time, the collection box 13 can be inserted into the conveyed coal. Utilizing the kinetic energy generated by the conveyed coal, the first baffle 16 can be pushed to move, and the spring 17 can be contracted. At this time, the feeding port 15 will be opened, and the coal can enter the interior of the collection box 13 through the feeding port 15. Subsequently, the rotating cylinder 6 continues to rotate. When the collection box 13 moves away from the coal, the resilience generated by the spring 17 can be utilized to push the first baffle 16 to reset and close the feeding port 15. Immediately afterwards, the direction of the collection box 13 will gradually change from downward to upward. At this time, under the action of gravity, the second baffle 18 can slide to open the discharge port 14. Then, the coal in the collection box 13 will fall into the interior of the rotating cylinder 6 through the discharge port 14, thus completing the sampling.
