Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 1-6 This utility model provides a technical solution:

[0026] A sampling device for pressurized material conveying includes a sampling mounting frame 26, a sampling moving drive 27, a sampling rotating drive 28, an outer sampling pipe 29, an inner sampling pipe 30, a conical end 36, and a discharge pipe 37. The fixed part of the sampling moving drive 27 is fixedly mounted on the sampling mounting frame 26. One end of the inner sampling pipe 30 is connected to the output part of the sampling moving drive 27. One end of the outer sampling pipe 29 is rotatably sleeved on and cooperates with the inner sampling pipe 30. The conical end 36 is sealed and fixedly mounted on the other end of the outer sampling pipe 29. At one end, one end of the discharge pipe 37 is located inside the inner material extraction pipe 30 and mates with the tapered end 36. The other end of the discharge pipe 37 extends through the side wall of the inner material extraction pipe 30 to the outside of the inner material extraction pipe 30. The discharge pipe 37 and the outer material extraction pipe 29 are sealed together. The material extraction rotation drive 28 is located on the output part of the material extraction movement drive 27 and is used to drive the outer material extraction pipe 29 to rotate on the inner material extraction pipe 30. The outer material extraction pipe 29 is provided with a first inlet 34, and the inner material extraction pipe 30 is provided with a second inlet 35 that mates with the first inlet 34. Both the material extraction movement drive 27 and the material extraction rotation drive 28 are pneumatic or hydraulic cylinders in the prior art. The pneumatic or hydraulic cylinders are controlled by different solenoid valves, which are electrically connected to the control center in the prior art, enabling automated sampling under the control of the control center. The cylinder of the material handling moving drive 27 is fixed on the material handling mounting frame 26, and the material handling rotation drive 28 drives the outer material handling tube 29 to rotate on the inner material handling tube 30. When the first inlet 34 on the outer material handling tube 29 and the second inlet 35 on the inner material handling tube 30 rotate to engage, the material in the ton bag in the ton bag box 69 enters the inner material handling tube 30 through the first inlet 34 and the second inlet 35, and then pushes the outer material handling tube 29, causing the outer material handling tube 29 to block the second inlet 35 and the inner material handling tube 30 to block the first inlet 34, thus completely separating the material in the inner material handling tube 30 from the material in the ton bag. Under the action of the material handling moving drive 27, the outer material handling tube 29 and the inner material handling tube 30 are inserted into or pulled out of the ton bag in the ton bag box 69. Nine sets of material-picking moving drive components 27 are provided on the material-picking mounting frame 26. Each material-picking moving drive component 27 can work independently, and the nine sets of material-picking moving drive components 27 can perform material-picking operations simultaneously. The conical end 36 is a conical end, which is sealed and fixedly connected to the end of the outer material-picking pipe 29. The conical end 36 has two functions: first, to seal the end of the outer material-picking pipe 29; second, to puncture the ton bag to facilitate the insertion of the outer material-picking pipe 29 into the ton bag. The output end of the discharge pipe 37 is located near the conical end 36, and the input end of the discharge pipe 37 passes through the side wall of the inner material-picking pipe 30. The outer material-picking pipe 29 does not contact the discharge pipe 37. The input end of the discharge pipe 37 is connected to the external blower in the prior art. The blower generates high air pressure to transport the material in the inner material-picking pipe 30 to the material collection box 63 through the conveying hose 38.

[0027] In some embodiments, a material picking mounting plate 32 is fixedly mounted on the output portion of the material picking moving drive 27, an inner material picking tube 30 is fixedly mounted on the material picking mounting plate 32, the fixed portion of the material picking rotation drive 28 is hinged to the material picking mounting plate 32, and the output portion of the material picking rotation drive 28 is hinged to the outer material picking tube 29. A material picking guide rod 33 is fixedly mounted on the material picking mounting frame 26, and the material picking mounting plate 32 is slidably mounted on the material picking guide rod 33. The material-receiving mounting plate 32 is fixedly connected to the piston rod of the material-receiving moving drive 27. The material-receiving moving drive 27 pushes the material-receiving mounting plate 32 to slide on the material-receiving guide rod 33. The material-receiving mounting plate 32 is used to install the material-receiving rotating drive 28 and the inner material-receiving tube 30. The cylinder of the material-receiving rotating drive 28 is hinged on the material-receiving mounting plate 32. The output shaft of the material-receiving rotating drive 28 is hinged to the outer material-receiving tube 29. The material-receiving rotating drive 28 drives the outer material-receiving tube 29 to rotate, so that the first feed port 34 and the second feed port 35 can be matched or misaligned.

[0028] In some embodiments, the first feed inlet 34 and the second feed inlet 35 are both located between the two ends of the discharge pipe 37. The sample material in the ton bag enters the inner feed pipe 30 after passing through the first feed inlet 34 and the second feed inlet 35. If the sample material enters the inner feed pipe 30 and is near the end of the conical end 36, the sample material at this location is less likely to enter the material collection box 63 through the conveying hose 38.

[0029] In some embodiments, the end of the internal material handling tube 30 is sealed and connected to one end of the conveying hose 38, and the other end of the conveying hose 38 is sealed and connected to the material collection assembly. The material collection assembly includes a material collection box 63, a door plug 64, a door plug drive 65, and a pressure relief pipe 66. The upper end of the material collection box 63 is sealed and connected to the conveying hose 38, and a release door is provided on the lower end of the material collection box 63. A door plug 64 is provided on the release door and is sealed and connected to the release door. The door plug 64 is provided on the output part of the door plug drive 65, and the door plug drive 65 is fixedly installed on the material collection box 63. A pressure relief pipe 66 communicating with the inside of the material collection box 63 is provided on the top of the material collection box 63. The material collection box 63 is used to store sample materials obtained from the ton bags inside the ton bag box 69. A release door is provided at the bottom of the material collection box 63 for releasing the material. A door stopper 64 seals the release door to prevent material from falling. When it is necessary to release material from the material collection box 63, the door stopper 64 is opened. The door stopper drive component 65 is a pneumatic or hydraulic cylinder, as used in the prior art. The door stopper drive component 65 is fixedly installed on the upper end of the material collection box 63, and drives the door stopper 64 to move up and down. Since the material is transported into the material collection box 63 by air pressure, a pressure relief pipe 66 is provided to release the gas pressure in the material collection box 63. The function of the conveying hose 38 is to transport the material in the inner feed pipe 30 to the material collection box 63.

[0030] In some embodiments, the material handling mounting frame 26 is provided with guide wheels 39 that cooperate with the conveying hose 38. The conveying hose 38 is a rubber conveying pipe, and one end of the conveying hose 38 moves together with the inner material handling pipe 30. The conveying hose 38 is sandwiched in the middle by two guide wheels 39. The guide wheels 39 are provided to prevent the conveying hose 38 from being damaged due to long-term friction between it and the material handling mounting frame 26.

[0031] In some embodiments, a guide plate 67 is fixedly provided on the material handling mounting frame 26, and the guide plate 67 is provided with a guide hole 68 that cooperates with the external material handling tube 29. In the process of material handling, the external material handling tube 29 moves a long distance. The guide hole 68 on the guide plate 67 can stabilize the external material handling tube 29 and prevent the end of the external material handling tube 29 from deviating too far under the action of gravity.
