[0002] Mechanical sampling devices are commonly used equipment in coal industries such as coal mines and thermal power plants for sampling coal. However, during long-term use, mechanical sampling devices often have coal blockage problems, which seriously affects their normal operation and sampling effect. At present, coal mechanical sampling devices include the following parts: sampling device, feeding belt, crusher, dividing belt, divider, sample collection device, bucket elevator, discarded belt, etc. Among them, the connection between the feeding belt and the crusher, the connection between the divider and the sample collection device, and the connection between the bucket elevator and the discarded belt are mostly connected by chute. When mechanically sampling wet coal and coal with high viscosity, the chute is the place where coal is most likely to be blocked. The traditional method of cleaning coal blockage usually uses a straight iron rod for dredging or a short shovel is inserted into the sampling device for cleaning. Due to the small space of the equipment and the corners of the connection, the efficiency of coal blockage cleaning is low and there are safety hazards. Utility Model Content

When the rotating motor 25 rotates, it drives the fixed cylinder 12 sleeved on the outside to rotate, and the connecting piece 24 movably connected on the side will shake at the same time, and make a circular motion with the rotating piece 240 as the center, driving the bottom rotating head 23 to rotate inside the spherical fixed block 22. Because the shaking of the connecting piece 24 will drive the slider 21 to move back and forth, it can make the dredging brush 210 fixedly connected to the bottom of the slider 21 to clean the inside of the sampling tube. In the dredging action of coal, a fixed groove 26 is recessed inwardly around the top of the rotating motor 25, and a fixed block 27 is fixedly connected inside the fixed groove 26. A movable part 28 is rotatably connected inside the fixed block 27, and a variable pitch rod 29 is rotatably connected inside the movable part 28. A dredging brush 210 is fixedly connected to the bottom of the slider 21. The dredging brush 210 is made of practical deformable metal and can change the shape of the dredging brush 210 according to the chute of the sampling tube. The power source arranged at one end of the variable pitch rod 29 will change the position of the movable part 28 on the outside of the variable pitch rod 29 when driving the internal threaded structure to rotate. The increase in the deflection angle of the rotating motor 25 will increase the rotation amplitude of the rotating motor 25. The larger the rotation amplitude, the larger the reciprocating motion amplitude of the dredging brush 210 at the bottom of the slider 21, and the higher the dredging efficiency.

[0022] See also Figure 1-3 The support assembly 1 includes a support frame 11, one end of the inner cavity of the support frame 11 is rotatably connected to a fixed cylinder 12, the fixed cylinder 12 is used to fix the pitch rod 29 arranged on the top of the rotating motor 25, one end of the support frame 11 extends outward and is fixedly connected to a motor 13, the motor 13 can drive the whole to rotate, so that the dredging brush 210 can dredge the coal stuck on the inner wall of the sampling tube in all directions, the bottom of the motor 13 is fixedly connected to a fixed plate 14, the fixed plate 14 is used to be installed at one end of the sampling tube when the sampling tube needs to be dredged, and dredge the coal blocked inside, the other end of the support frame 11 is fixedly connected to a fixing member 15, the bottom of the fixing member 15 is provided with a slide groove 151, the side of the fixing member 15 is provided with a limiting groove 150, the limiting groove 150 and the slide groove 151 provide operating space for the reciprocating motion of the slider 21 and the limiting groove 150.

[0023] See also Figure 1 , 3-5, a threaded structure is provided in the middle of the pitch-changing rod 29, and both ends of the pitch-changing rod 29 are fixedly connected to the side walls of the fixed cylinder 12, the slider 21 is slidably connected to the inside of the fixing member 15, the dredging brush 210 passes through the slide groove 151 opened at the bottom of the fixing member 15, the spherical fixing block 22 is spherical, a hole is opened on the top of the spherical fixing block 22, and a rotating head 23 is connected to the inside for rotation, both ends of the connecting member 24 are bent to one side, a power source is provided at one end of the pitch-changing rod 29, and the output end of the power source is connected to the threaded structure, which can drive the threaded structure to rotate, and there is a gap between the rotating motor 25 and the externally sleeved fixed cylinder 12, which provides space for the rotation of the rotating motor 25.

[0024] When in use, first clamp the fixing plate 14 on one end of the sampling tube that needs to be cleared and cleaned. Since the power source arranged inside one end of the pitch change rod 29 can drive the threaded structure of the rotation connection inside the pitch change rod 29 to rotate, the position of the movable part 28 sleeved on the outside of the threaded structure is changed, and the amplitude of the shaking of the connecting part 24 driven by the rotating motor 25 is changed. The increase in the deflection angle of the rotating motor 25 will increase the rotation amplitude of the rotating motor 25. The larger the rotation amplitude, the spherical fixing block 22 sleeved on the outside of the rotating head 23 can drive the spherical fixing block The slider 21 fixedly connected at one end of 22 reciprocates inside the fixing part 15, so that the unclogging brush 210 fixedly connected at the bottom of the slider 21 dredges the inside of the sampling tube back and forth, and the fixed cylinder 12 sleeved on the outside of the rotating motor 25 rotates synchronously with the rotating motor 25 when the rotating motor 25 rotates. Since the motor 13 is fixed on the surface of the fixing plate 14, when the unclogging brush 210 dredges the inside of the sampling tube back and forth, it can also drive the supporting frame 11 to rotate, so that the unclogging brush 210 can dredge the inner wall of the sampling tube in all directions without dead ends.
