By inserting the bottom end of the vertical cylinder 2 into the coal pile so that the coal contacts the rotating spiral conveying shaft 3, the coal can be transported upward in the vertical cylinder 2 and output outward from the discharge pipe 9 to complete the coal sampling.

[0028] An adjustment component 6 is movably installed on the vertical cylinder 2, and multiple groups of vertical rods 10 are hinged on the adjustment component 6. The adjustment component 6 can drive the vertical rods 10 to move. A through opening 11 is opened on each group of vertical rods 10, and a connecting rod 12 is hinged inside each group of through openings 11. Multiple groups of U-shaped plates 13 are fixedly connected to the vertical cylinder 2, and the other end of each group of connecting rods 12 is hinged on the U-shaped plate 13. With the cooperation of the connecting rod 12, when the vertical rod 10 moves, the angle can change. By contacting the coal pile through the bottom of the vertical rod 10, the sampling device can be supported and limited.

[0029] like Figure 1 、 Figure 2 and Figure 3 As shown, the adjustment component 6 includes an outer cylinder 601 mounted on the vertical cylinder 2, and the lower end surface of the outer cylinder 601 is rotatably connected to the connecting ring 602, so that the rotation of the outer cylinder 601 will not affect the connecting ring 602. A plurality of groups of grooves 603 are provided on the connecting ring 602, and the top ends of each group of vertical rods 10 are hinged inside the grooves 603, so that the connecting ring 602 can drive the vertical rods 10 to move when it moves.

[0030] Among them, the inner wall of the outer cylinder 601 is provided with a first thread 604, and the vertical cylinder 2 is provided with a second thread 605 matching the first thread 604. The outer cylinder 601 is threadedly connected to the vertical cylinder 2. Through the cooperation of the first thread 604 and the second thread 605, the outer cylinder 601 can move on the surface of the vertical cylinder 2 by rotation, thereby driving the connecting ring 602 to move, thereby completing the adjustment of the angle of the vertical rod 10.

[0031] like Figure 4As shown, the usage of the adjustment component 6 is not limited to one method. The adjustment component 6 can also include an outer cylinder 601 that is sleeved on the vertical cylinder 2. The lower end surface of the outer cylinder 601 is fixedly connected to a connecting ring 602. The outer cylinder 601 can directly drive the connecting ring 602 to slide on the surface of the vertical cylinder 2 to adjust its usage position. A plurality of groups of grooves 603 are provided on the connecting ring 602. The top of each group of vertical rods 10 is hinged to the inside of the groove 603. A threaded hole 606 is provided on the outer cylinder 601. The inner wall of the threaded hole 606 is threadedly connected to a fixing bolt 607. By installing the fixing bolt 607 into the threaded hole 606 and tightening the fixing bolt 607, the outer cylinder 601 can be fixed. It is also convenient to use.

[0032] like Figure 1 and Figure 3 As shown, multiple groups of cross bars 7 are fixedly connected to the outer cylinder 601, and the ends of the multiple groups of cross bars 7 away from the outer cylinder 601 are fixedly connected to a rotating ring 8. The arranged cross bars 7 and the rotating ring 8 form a turntable, which can facilitate the staff to use it to operate the outer cylinder 601 and facilitate its movement or rotation.

[0033] like Figure 1 and Figure 5 As shown, one end of the spiral conveyor shaft 3 extends to the bottom of the vertical cylinder 2. When in use, the spiral conveyor shaft 3 will first contact the coal pile. By utilizing its protruding front end, the vertical cylinder 2 can be better inserted into the coal pile. The bottom end of the vertical cylinder 2 is fixedly connected with a wear-resistant sleeve 5, which can protect the bottom of the vertical cylinder 2 and thus increase the service life of the device.

[0034] like Figure 1 and Figure 2 As shown, the top of the vertical cylinder 2 is fixedly connected to a motor 1, the output end of the motor 1 is fixedly connected to a spiral conveying shaft 3, the motor 1 is fixedly connected to a handle 4, and the vertical cylinder 2 is fixedly connected to a discharge pipe 9 and a scale 17. The motor 1 drives the spiral conveying shaft 3 to rotate to transport and sample the coal. The scale 17 can facilitate the staff to check the depth of the vertical cylinder 2 inserted into the coal pile, which is conducive to accurately controlling the sampling depth.

[0035] like Figure 1 and Figure 3 As shown, the bottom end of each set of vertical poles 10 is longer than the vertical tube 2. When the vertical poles 10 are retracted and in contact with the vertical tube 2, the spiral conveying shaft 3 protruding from the bottom thereof can be sealed to play a protective role.
