Description

Technical Field

[0001] This utility model relates to the field of total moisture testing technology, and in particular to a leveling device for total moisture testing. Background Technology

[0002] When testing the total moisture content of a sample, the reduced sample is typically placed in a sample container, which is then placed in a drying oven for drying. However, when the coal sample falls into the sample pan after reduction, the free fall causes accumulation, resulting in uneven sample thickness. This not only affects drying efficiency but also interferes with the moisture test results. Therefore, the sample in the sample pan needs to be spread out evenly before weighing. The thinner and more uniformly the sample is spread in the sample container, the shorter the drying time and the better the drying effect.

[0003] Existing leveling devices typically use drive components to move or rotate scrapers or rakes to stir the sample in the sample container and achieve leveling. However, during leveling, when the coal sample comes into contact with the leveling device, a rigid load is usually generated, causing the robot's robotic arm to be momentarily overloaded, leading to system shutdown, difficulty in coordinating with the robot, and low leveling efficiency. Furthermore, during subsequent leveling, the leveling device rotates in rigid contact with the coal sample, resulting in large load fluctuations and insufficient system stability. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a leveling device for total moisture testing that has good stability, high leveling efficiency and good leveling effect.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A leveling device for total moisture testing includes a leveling mechanism, which includes a mounting base, an elastic element, and a scraper assembly disposed on the mounting base. The elastic element is disposed on the mounting base and is used to buffer the load generated by the scraper assembly contacting the sample in the sample tray.

[0007] As a further improvement to the above technical solution:

[0008] The leveling mechanism also includes a support frame, which includes an upper frame plate. The mounting base is located below the upper frame plate, and the elastic element is arranged vertically and connected between the upper frame plate and the mounting base.

[0009] A lower shelf is connected to the lower part of the upper shelf, and the mounting base is movably mounted on the lower shelf.

[0010] The scraper assembly includes a scraper driver and a scraper. The scraper driver is mounted on a mounting base, and the scraper is connected to the output end of the scraper driver.

[0011] The scraper blade is arc-shaped.

[0012] The scraper blade is provided with multiple clearance sections.

[0013] The leveling mechanism also includes a base, on which a vertical guide rail is provided, and a slider is slidably mounted on the vertical guide rail. The mounting base is connected to the slider.

[0014] It also includes a frame, a transfer device and a balance, wherein the balance and the leveling mechanism are mounted on the frame, and the transfer device is used to lift and transfer the sample tray.

[0015] The frame is also equipped with an air knife for blowing the surface of the balance.

[0016] The bottom of the frame is equipped with a receiving tray.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. The leveling device for total moisture testing of this utility model, by setting an elastic element, allows the scraper assembly to make flexible contact with the sample. When the scraper assembly first contacts the sample, the elastic element can buffer the instantaneous load generated between the scraper assembly and the sample, preventing the instantaneous load from being too large. This allows the leveling device for total moisture testing of this embodiment to work in conjunction with the robotic arm of a robot, etc., with high leveling efficiency. When the scraper assembly moves to level the sample, the elastic element can buffer the working load generated between the scraper assembly and the sample, reducing load fluctuation and providing good stability. Furthermore, under the action of the elastic force of the elastic element, the scraper assembly can always be pressed firmly on the sample, resulting in more uniform leveling and a better leveling effect.

[0019] 2. The leveling device for total moisture testing of this utility model has a lower frame plate installed below the mounting base. When not in operation, the lower frame plate can support the mounting base and the scraper assembly on the mounting base, preventing the weight of the mounting base and the scraper assembly from acting entirely on the elastic element and extending the service life of the device.

[0020] 3. The leveling device for total moisture testing of this utility model has an arc-shaped scraper and multiple avoidance parts, which can reduce the resistance during leveling, improve the uniformity of leveling, and achieve a better leveling effect.

[0021] 4. The leveling device for total moisture testing of this utility model, by setting a vertical guide rail, guides the mounting base and scraper assembly when the elastic element is compressed, preventing the mounting base and scraper assembly from shifting, further reducing load fluctuation and improving stability.

[0022] 5. The leveling device for total moisture testing of this utility model uses an air knife to blow high-pressure air across the balance surface, preventing coal samples from adhering to or falling onto the balance surface and improving the accuracy of weighing data.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] like Figures 1 to 4 As shown, the leveling device for total moisture testing in this embodiment includes a leveling mechanism 2. The leveling mechanism 2 includes a mounting base 21, an elastic element 22, and a scraper assembly 24 disposed on the mounting base 21. The elastic element 22 is disposed on the mounting base 21 and is used to buffer the load generated by the contact between the scraper assembly 24 and the sample in the sample tray 9.

[0033] In this embodiment of the leveling device for total moisture testing, during operation, the sample tray 9 containing the sample is lifted to the leveling mechanism 2. The sample tray 9 rises, allowing the scraper assembly 3 to insert into the sample, and the scraper assembly 3 levels the sample. This leveling device for total moisture testing, by incorporating an elastic element 22, ensures that the scraper assembly 24 is in flexible contact with the sample. When the scraper assembly 24 first contacts the sample, the elastic element 22 buffers the instantaneous load generated between the scraper assembly 24 and the sample, preventing excessive instantaneous load. This allows the leveling device for total moisture testing to work collaboratively with robotic arms, achieving high leveling efficiency. When the scraper assembly 24 moves to level the sample, the elastic element 22 buffers the working load generated between the scraper assembly 24 and the sample, reducing load fluctuations and improving stability. Furthermore, under the elastic force of the elastic element 22, the scraper assembly 24 remains firmly pressed against the sample, resulting in more uniform leveling and a better leveling effect.

[0034] Preferably, in this embodiment, the elastic element 22 is a spring. Of course, in other embodiments, the elastic element 22 can also be a rubber element, etc.

[0035] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, the leveling mechanism 2 further includes a support 23, which includes an upper frame plate 231, a mounting base 21 located below the upper frame plate 231, and an elastic element 22 vertically arranged and connected between the upper frame plate 231 and the mounting base 21. When the sample tray 9 rises and the scraper assembly 3 is inserted into the sample, the elastic element 22 is compressed upward, so that the sample and the scraper assembly 24 make flexible contact. The structure is simple and reliable.

[0036] Furthermore, in this embodiment, a lower frame plate 232 is connected below the upper frame plate 231, and the mounting base 21 is movably disposed on the lower frame plate 232. By disposing of the mounting base 21 below the lower frame plate 232, in the non-working state, the lower frame plate 232 can support the mounting base 21 and the scraper assembly 3 on the mounting base 21, preventing the weight of the mounting base 21 and the scraper assembly 3 from acting entirely on the elastic member 22, thereby extending the service life of the device.

[0037] Furthermore, in this embodiment, the scraper assembly 24 includes a scraper driver 241 and a scraper 242. The scraper driver 241 is mounted on the mounting base 21, and the scraper 242 is connected to the output end of the scraper driver 241. The scraper driver 241 (e.g., a motor) drives the scraper 242 to rotate to flatten the sample, resulting in a simple and reliable structure.

[0038] Furthermore, in this embodiment, the scraper 242 is arc-shaped, and a plurality of clearance portions 2421 are provided on the scraper 242. By making the scraper 242 arc-shaped and providing a plurality of clearance portions 2421, the resistance during leveling can be reduced, the uniformity of leveling can be improved, and the leveling effect can be better.

[0039] Furthermore, in this embodiment, the leveling mechanism 2 also includes a base 1, on which a vertical guide rail 11 is provided, and a slider 12 is slidably mounted on the vertical guide rail 11. The mounting seat 21 is connected to the slider 12. By setting the vertical guide rail 11, when the elastic element 22 is compressed, it guides the mounting seat 21 and the scraper assembly 24, preventing the mounting seat 21 and the scraper assembly 24 from shifting, further reducing load fluctuations and improving stability.

[0040] Furthermore, such as Figures 1 to 4 As shown, this embodiment also includes a frame 4, a transfer device 5, and a balance 6. The balance 6 and the leveling mechanism 2 are mounted on the frame 4 (specifically, the base 1 is mounted on the frame 4). The transfer device 5 is used to lift and transfer the sample tray 9. During operation, the transfer device 5 (e.g., a transfer robot) lifts the sample tray 9 and inserts the scraper 242 into the sample. The scraper drive 241 drives the scraper 242 to rotate and level the sample. After leveling, the transfer device 5 transfers the sample tray 9 to the balance 6 for weighing. The leveling and weighing processes are tightly connected, resulting in high efficiency.

[0041] Furthermore, such as Figure 1 and Figure 2 As shown in this embodiment, the frame 4 is also equipped with an air knife 7 for purging the surface of the balance 6. The air knife 7 uses high-pressure air to purge the surface of the balance 6, preventing coal samples from adhering to or falling onto the surface of the balance 6, thereby improving the accuracy of the weighing data.

[0042] Furthermore, such as Figure 1 and Figure 2As shown, in this embodiment, the bottom of the frame 4 is provided with a receiving tray 41. During the leveling process, due to the stirring action, a small amount of coal sample particles will fall off and into the receiving tray 41. In addition, when the air knife 7 blows the balance 6, the coal sample adhering to the surface of the balance 6 will also fall into the receiving tray 41, which is convenient for cleaning and recycling.

Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present utility model using the methods and techniques disclosed above, or modify it into equivalent embodiments with equivalent changes, without departing from the spirit and technical solution of the present utility model. Therefore, any simple modifications, equivalent substitutions, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
