[0016] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic sampling and weighing device for coal at full depth in automobiles, comprising: Sampling cylinder 1; A recyclable sampling mechanism 2 is installed on the sampling cylinder 1 and is used for quantitative sampling. Depth adjustment mechanism 3 is located above sampling cylinder 1 and is used to adjust the sampling depth. The recyclable sampling mechanism 2 includes a sampling motor 21, an output pipe 22, and a cylindrical assembly 24. The sampling motor 21 is fixedly installed on the top of the sampling cylinder 1. The output pipe 22 is fixedly connected to the outer wall of the sampling cylinder 1, and an electric gate valve 23 is fixedly connected to the bottom of the output pipe 22.

A weighing sensor 26 is fixedly installed on the top of the support base 25. A frame 27 is fixedly installed on the top of the weighing sensor 26. A sampling cylinder 29 is fixedly installed on the inner wall of the frame 27. Initially, the electric gate valve 23 is in the open state, and a screw is fixedly connected to the output shaft of the sampling motor 21. The rod and screw are located inside the sampling cylinder 1. The sampling motor 21 is controlled to work, which drives the screw to rotate and extract coal samples from the bottom of the sampling cylinder 1. The samples are then output from the electric gate valve 23. This allows the coal samples from the vehicle to flow through the internal structure, fully carrying out the coal samples from the vehicle, greatly reducing the amount of coal samples from the vehicle mixed into the current coal sample. The weighing sensor 26 can monitor the overall weight of the sampling cylinder 29. The increase in weight is the sampling amount. The data monitored by the weighing sensor 26 is fed back to the controller. After the specified sampling amount is reached, the controller will control the sampling motor 21 to stop working and close the electric gate valve 23 at the same time, realizing the function of quantitative sampling and reducing coal sample waste.

[0017] As one implementation method in this embodiment, such as Figure 3As shown, a strip groove 291 is provided on the side of the sampling tube 29. A gate 292 is slidably connected in the inner cavity of the strip groove 291. A support block 293 is fixedly installed on the outer wall of the sampling tube 29. An electric telescopic rod 294 is fixedly installed on the inner wall of the support block 293. Initially, the gate 292 is not located at the bottom of the inner cavity of the sampling tube 29, and the coal sample output from the electric gate valve 23 will pass through the inner cavity of the sampling tube 29.

[0018] As one implementation method in this embodiment, such as Figure 3 As shown, a connecting block 295 is fixedly installed at the telescopic end of the electric telescopic rod 294. The connecting block 295 is fixedly installed on the side of the gate 292. When sampling, the electric telescopic rod 294 is controlled to retract, which will drive the gate 292 to slide inside the strip groove 291 through the connecting block 295, thereby sealing the bottom of the inner cavity of the sampling tube 29 and realizing the sampling function.

[0019] As one implementation method in this embodiment, such as Figure 2 As shown, a support arm 28 is fixedly installed on the outer wall of the cylindrical kit 24. The support arm 28 is fixedly installed at the bottom of the support base 25. The support arm 28 can be used to reinforce the support base 25.

[0020] As one implementation method in this embodiment, such as Figure 4 As shown, the depth adjustment mechanism 3 includes a mounting base 31, a connecting frame 32 is fixedly installed on the inner wall of the mounting base 31, and a lifting telescopic rod 33 is fixedly installed at the bottom of the inner cavity of the connecting frame 32. During construction, this structure is installed on the bridge structure from the mounting base 31. Through the operation of the bridge structure, this structure can be moved on the plane. The lifting telescopic rod 33 is controlled to work, which can drive the sampling cylinder 1 to rise and fall as a whole. The sampling depth can be designed.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, a disc 34 is fixedly installed at the telescopic end of the lifting telescopic rod 33, and a slide rod 35 is fixedly installed on the top of the disc 34. The slide rod 35 is slidably connected to the connecting frame 32. During the process of the lifting telescopic rod 33 driving the sampling cylinder 1 to rise and fall, the slide rod 35 will slide on the connecting frame 32 to improve stability.

[0022] As one implementation method in this embodiment, such as Figure 4 As shown, a connecting arm 36 is fixedly installed at the bottom of the disc 34, and a connecting kit 37 is fixedly installed at the bottom of the connecting arm 36. The connecting kit 37 is fixedly sleeved on the outer wall of the sampling cylinder 1. Through the cooperation of the disc 34, the connecting arm 36 and the connecting kit 37, the sampling cylinder 1 can be rigidly connected to the telescopic end of the lifting telescopic rod 33.

[0023] It is worth noting that the controller, sampling motor 21, electric gate valve 23, weighing sensor 26, electric telescopic rod 294, and lifting telescopic rod 33 in this solution are devices that can be purchased commercially by those skilled in the art. No structural modifications have been made to these devices in this paper. Therefore, those skilled in the art are familiar with their working principles based on their professional knowledge and can apply them proficiently. Thus, this paper will not elaborate further on this aspect. Furthermore, this solution aims to protect the physical structure, but does not protect the circuitry and software control. The mention of the processing circuit in this paper is merely a supplementary explanation of the feasibility and authenticity of this utility model. This utility model does not require protection of the algorithm and circuitry technology. It is worth emphasizing that although this solution does not elaborate on the electronic control program, those skilled in the art can be familiar with and apply it based on their professional knowledge.

[0024] Working principle: In use, this structure is installed on the bridge structure from the mounting base 31. The bridge structure moves the structure on the plane. After moving to the sampling point, the lifting telescopic rod 33 is controlled to lift the entire sampling cylinder 1. The sampling depth can be designed. The sampling motor 21 is controlled to rotate the screw, extracting coal samples from the bottom of the sampling cylinder 1. The samples are then output from the electric gate valve 23. At this time, the gate 292 is not located at the bottom of the inner cavity of the sampling cylinder 29. The coal sample output from the electric gate valve 23 will pass through the inner cavity of the sampling cylinder 29. After running for a period of time... When the electric telescopic rod 294 retracts, it drives the gate 292 to slide inside the strip groove 291 via the connecting block 295, sealing the bottom of the sampling cylinder 29 and realizing the sampling function. The weighing sensor 26 can detect the overall weight of the sampling cylinder 29, and the increase in weight is the sampling amount. The data monitored by the weighing sensor 26 is fed back to the controller. After the specified sampling amount is reached, the controller will control the sampling motor 21 to stop working and close the electric gate valve 23. Then, the structure is reset to the initial position, and the gate 292 is withdrawn from the bottom of the sampling cylinder 29, discharging the coal sample to the next process.
