[0040] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0041] Combine the following Figures 1 to 3 The present invention describes a powder dropping mechanism.

[0042] like Figures 1 to 3 As shown, the embodiment of the utility model provides a powder dropping mechanism, including a mounting frame 1, a storage device, a conveying device, a vibration device, and a guiding device. Specifically, as Figure 1As shown, the mounting frame 1 is fixedly arranged. Specifically, the mounting frame 1 can be fixedly connected to the reaction furnace 15, for example, by bolt connection, so as to serve as a supporting and fixing structure of the entire mechanism. The storage device and the vibration device are movably arranged on both sides of the mounting frame 1, specifically, they are respectively located on the upper and lower sides of the mounting frame 1. The storage device is used to store powder materials, and a discharge hole is provided at the bottom of the storage device. Among them, the size, shape and number of the discharge holes can be specifically determined according to the actual use conditions to meet the design requirements of the amount of material dropped and the uniformity of the material dropped. It can be understood that in a static state, the powder materials will interact and squeeze to block the discharge holes. The vibration device is used to transmit vibration to the storage device, so that the powder materials in the storage device are evenly sprinkled on the sample under the combined action of gravity and vibration. The vibration device can select the existing commonly used vibrator 12, and by adjusting its vibration time and vibration frequency, the amount of powder material sprinkled can be accurately controlled to adapt to different experimental needs and improve the flexibility and adjustability of the experiment. The conveying device is arranged below the storage device, and is used to drive the sample to move so as to transfer the sample to the reaction furnace 15. Thus, during the movement of the sample, the powder catalyst is scattered, which improves the efficiency of the material dropping and ensures the uniformity of the material dropping. The guide device is arranged between the storage device and the vibration device, and the guide device is slidably connected to the mounting frame 1, and the guide device moves along the height direction of the mounting frame 1. Thus, the movement direction of the storage device is restricted, so that the storage device can stably and reliably reciprocate in the vertical direction.

[0043] With such arrangement, the conveying device drives the sample to move toward the reaction furnace 15. In the process of passing through the discharge hole, under the action of the vibration device, the powdered catalyst falls from the storage device onto the sample surface, thereby realizing automatic and uniform scattering of the powder, reducing the need for manual operation, reducing labor intensity, improving operating efficiency, avoiding the problem of uneven scattering that may occur during manual operation, eliminating the impact of human errors, and effectively improving the precision and accuracy of the test results. And with the coordinated action of the guide device, the vibration is limited to the height direction, further improving the efficiency of the dry powder scattering. It should be noted that, with Figure 1 As for the placement position of the powder dropping mechanism shown in the figure, the up and down directions in the figure refer to the up and down positions, height directions, and vertical directions, and the lower end in the figure is the bottom of the storage device.

[0044] In the embodiment of the utility model, the powder dropping mechanism also includes a detection device 2 and a controller, and the controller is connected to the detection device 2, the vibration device and the conveying device in communication, for example, by an electrical connection. Specifically, the detection device 2 is used to detect the position of the sample, for example, a commonly used position sensor such as a laser sensor can be selected. The controller can select an existing commonly used device, such as a single-chip microcomputer, an editable logic controller, etc., so its specific structure and its electrical connection relationship are not repeated here. The controller is used to control the vibration device and the conveying device to start working when it detects that the sample is located directly below the discharge hole. Thus, during the transmission of the sample, a layer of catalyst is evenly sprinkled on its surface. In addition, it can be understood that when it is detected that the sample has completely passed through the discharge port, the controller is also used to control the vibration device to stop working and no longer sprinkle. At this time, the conveying device continues to work and transports the sample to the reactor 15. Such a setting can realize the automatic control of the device, reduce the influence of external factors on the experimental results, improve the accuracy and reliability of the experiment, and enhance the scientificity and credibility of coal quality detection. And the operation process is simple, no complicated manual operation steps are required, the training cost of the operator is reduced, and the risk of operating errors is reduced.

[0045] As an optional embodiment of the present utility model, the guide device includes a guide rod 3, such as Figure 3 As shown, the guide rod 3 is slidably connected to the mounting frame 1, and the guide rod 3 moves along the height direction of the mounting frame 1. The guide rod 3 passes through the mounting frame 1, one end of the guide rod 3 is connected to the storage device, and the other end is connected to the vibration device. In this way, the moving direction of the storage device is limited by the guide rod 3, so that the powder can be reliably sprinkled on the sample. In addition, the guide rod 3 can be set to multiple, and the specific number can be determined according to actual use requirements to better play a guiding role. It should be noted that, as shown in the figure, Figure 3 As for the placement position of the powder dropping mechanism shown in the figure, the up and down direction in the figure is the height direction of the mounting frame 1.

[0046] In an optional embodiment of the present invention, the powder dropping mechanism further includes an elastic member 4, which is disposed between the mounting frame 1 and the vibration device. One end of the elastic member 4 abuts against the mounting frame 1, and the other end abuts against the vibration device. Specifically, the elastic member 4 can be a spring. Figure 2 As shown, the vibration device includes a vibrator 12, a fixing plate 13 and a base 14, and the vibrator 12 is connected to the base 14 through the fixing plate 13, for example, by bolts. One end of the guide rod 3 is fixedly connected to the storage device, and the other end is fixedly connected to the base 14, for example, by bolts. One end of the spring abuts against the mounting frame 1, and the other end abuts against the base 14. In this way, the elastic member 4 can play a buffering support role to avoid direct rigid contact.

[0047] Furthermore, in the embodiment of the utility model, the mounting frame 1 and the vibration device are respectively provided with limiting grooves adapted to the elastic member 4, and the elastic member 4 extends into the limiting grooves. Such a configuration can effectively fix and position the elastic member 4, prevent unnecessary movement or dislocation during the vibration process, and improve the stability and reliability of the system.

[0048] In a specific embodiment of the present invention, the powder dropping mechanism further includes a shock absorbing member 5, such as a rubber shock absorbing block. Figure 3 As shown, the shock absorbing member 5 is sleeved on the guide rod 3, and the shock absorbing member 5 is arranged between the guide rod 3 and the mounting frame 1, and the shock absorbing member 5 is slidably connected with the guide rod 3. In this arrangement, the shock absorbing member 5 can play a role in buffering and absorbing vibrations, thereby reducing the noise generated during vibration. In addition, the shock absorbing member 5 and the guide rod 3 are arranged one by one.

[0049] In the embodiment of the utility model, the material storage device includes a material tube 6, a material tube rack 7, and a support seat. Specifically, the material tube 6 is used to store powder materials to meet the experimental use requirements. The material tube rack 7 is used to fix the material tube 6. For example, the material tube rack 7 is designed to be T-shaped, such as Figure 3 As shown, its upper end is plugged and connected with the material pipe 6, and the material pipe 6 is inverted in the material pipe rack 7. The bottom of the material pipe rack 7 is provided with a discharge hole, and the pipe mouth of the material pipe 6 is connected with the discharge hole. The support seat is arranged below the material pipe rack 7, and is fixedly connected to the lower end of the material pipe rack 7, and the support seat is provided with a gap for the conveying device to pass through. Thus, an installation space is provided for the conveying device to realize the powder spilling during the sample transmission process. It should be noted that, as shown in FIG. Figure 3 For the placement position of the powder dropping mechanism shown in the figure, the up and down directions in the figure are the upper and lower positions referred to.

[0050] In a specific embodiment of the present invention, the support base includes a base 8 and a pair of support columns 9 arranged at intervals. Figure 3 As shown, the base 8 is movably arranged on the mounting frame 1. One end of a pair of support columns 9 is connected to the base 8, and the other end is connected to the material pipe rack 7, for example, by bolts. A gap is formed between the pair of support columns 9 for the conveying device to pass through. Thus, a door-type bracket is constructed, which has a simple structure and is stable and reliable. In addition, one end of the guide rod 3 is fixedly connected to the base 8, for example, by bolts. Under the action of gravity, the base 8 is supported on the shock absorbing member 5.

[0051] As an optional embodiment of the present utility model, the conveying device includes a conveying track 10, a conveying block 11, and a driving assembly. Figure 2As shown, the conveying track 10 is arranged below the material tube rack 7, and the conveying track 10 passes through the gap between a pair of support columns 9, and the conveying track 10 extends to the reaction furnace 15. The conveying block 11 is slidably connected to the conveying track 10 and moves along the conveying track 10. The conveying block 11 is used to receive the sample. The driving component (not shown in the figure) is used to drive the conveying block 11 to move, thereby driving the sample to move. The driving component can select the existing commonly used linear driving mechanism, such as a motor, a ball screw, a gear rack, a sprocket chain and other driving forms, and make adaptive adjustments to realize driving the conveying block 11 to move along the conveying track 10.

[0052] In summary, the embodiment of the utility model provides a powder dropping mechanism, including a storage device, a vibration device, a conveying device, a guide device, an elastic member 4, a shock absorbing member 5, a sensor, etc., aiming to design an automated powder dropping device to solve the problems of complex operation, low efficiency, high labor intensity, and uneven dropping in the manual addition of powder catalysts in existing coal quality detection experiments. The powder dropping mechanism of this embodiment simplifies the operation process, improves work efficiency, reduces the labor burden of operators, and ensures that the powder catalyst is evenly dropped on the surface of the sample, thereby improving the accuracy and reliability of the experimental data, and providing a simpler and more efficient experimental solution for the field of coal quality detection.

[0053] Specifically, the robot grabs the conveying block 11 carrying the sample and places it on the conveying track 10. When the sensor detects that the conveying block 11 is located directly below the discharge hole, it sends a signal to the controller. The controller receives the signal, controls the vibration device to vibrate, and the conveying device conveys the conveying block 11 toward the reaction furnace 15. Therefore, during the movement of the conveying block 11, the dry powder in the material pipe 6 is evenly sprinkled onto the conveying block 11 through the bottom opening of the material pipe rack 7 under the combined action of gravity and vertical vibration, so as to form a layer of catalyst on the surface of the sample. The amount of dry powder sprinkled can be controlled by the vibration time and vibration frequency of the vibration device.

[0054] The coal quality detection device provided by the utility model is described below. The coal quality detection device described below and the powder dropping mechanism described above can correspond to each other.

[0055] The embodiment of the utility model also provides a coal quality detection device, including a powder dropping mechanism as in the above-mentioned embodiments. In this way, the conveying device drives the sample to move toward the reaction furnace 15. In the process of passing through the discharge hole, under the action of the vibration device, the powder catalyst falls from the storage device onto the surface of the sample, thereby realizing the automatic and uniform scattering of the powder, reducing the need for manual operation, reducing labor intensity, improving operating efficiency, avoiding the problem of uneven scattering that may occur in manual operation, eliminating the influence of human errors, and effectively improving the precision and accuracy of the test results. And under the synergistic effect of the guide device, the vibration is limited to the height direction, further improving the efficiency of the dry powder scattering. The derivation process of this beneficial effect is roughly similar to the derivation process of the beneficial effect of the above-mentioned powder dropping mechanism, so it will not be repeated here.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
