Description

Technical Field

[0001] This utility model relates to the technical field of sample pretreatment equipment, and in particular to a high-efficiency sample pulverizer. Background Technology

[0002] In materials analysis, laboratory testing, and industrial production, sample pulverizers are crucial equipment for sample pretreatment, and their performance directly affects the accuracy of subsequent testing results and production efficiency. Existing sample pulverizers face the following technical bottlenecks in practical applications:

[0003] On the one hand, traditional equipment has a relatively fixed structural design and insufficient adjustment flexibility of the crushing components, making it difficult to efficiently adapt to the sample processing needs of different particle sizes. Furthermore, the inspection and maintenance of key components (such as crushing rods and crushing blades) requires a complex disassembly process, resulting in long equipment downtime and high maintenance costs.

[0004] On the other hand, during the crushing process, vibration or uneven load may occur due to structural design defects, which not only affects the uniformity of crushing but may also cause equipment malfunctions. At the same time, the equipment has low space utilization when idle, especially in the compact layout of laboratories or industrial settings, where the fixed structure of traditional equipment often leads to wasted space.

[0005] In addition, the existing equipment's screening and discharge mechanism during material crushing is not optimized enough, making it impossible to achieve simultaneous and efficient crushing and screening operations, which in turn affects the overall processing efficiency.

[0006] To address the above problems, this utility model proposes a high-efficiency sample pulverizer.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

The tilt angle of the mounting plate 2 can be adjusted as needed, so that the top cover 3 can be adjusted from inside the housing 1 to above the housing 1 when needed, which facilitates inspection and maintenance and the replacement of the top cover 3.

[0047] The drive motor 4 is fixedly installed on the top side of the mounting plate 2, and the telescopic square shaft 41 is fixedly installed on the output shaft of the drive motor 4. The top cover 3 is rotatably installed with a fixing sleeve 42 that is fixedly connected to the bottom end of the telescopic square shaft 41. The bottom end of the telescopic square shaft 41 is fixedly connected to the fixing sleeve 42 by bolts. Multiple rotating shafts 5 are rotatably installed on the top cover 3 around the fixing sleeve 42.

[0048] The top ends of multiple rotating shafts 5 extend above the top cover 3 and are respectively fixedly fitted with driven gears 51. The fixed sleeve 42 is provided with drive gears 52 that mesh with multiple driven gears 51, which can transmit driving force to the rotating shafts 5 when the drive motor 4 is working.

[0049] A rectangular opening is provided on one side of the box body 1. A servo motor 601 is fixedly installed at the bottom of the box body 1, and the top of the output shaft of the servo motor 601 is rotatably connected to the inner wall of the top side of the rectangular opening. The mounting base 6 is set inside the rectangular opening and is fixedly connected to the output shaft of the servo motor 601. Two trays 61 are symmetrically hinged and installed on the top of the two sides of the mounting base 6. Multiple fixing frames are fixedly installed on the bottom side of each of the two trays 61. Support wheels 62 are rotatably installed on the multiple fixing frames. The support wheels 62 on the bottom side of the trays 61 inside the box body 1 roll in contact with the inner wall of the bottom of the box body 1, which can provide stable support for the trays 61, thereby ensuring the stability of the trays 61 during the sample crushing process.

[0050] Both trays 61 have through openings, and the crushing container 7 is snapped into one of the trays 61.

[0051] Specifically, in order to avoid relative stability when the support wheel 62 loses contact with the bottom inner wall of the box 1, L-shaped grooves are provided on the top of both sides of the mounting base 6, and the two trays 61 are respectively hinged and installed in the corresponding L-shaped grooves.

[0052] Specifically, in order to facilitate flipping the tray 61 upwards and fixing it to the box 1 by magnetic block 63 when not in use, thereby reducing the space occupied by the device in the idle state, magnetic block 63 is fixedly installed on the top side of the tray 61.

[0053] Specifically, in order to screen the crushed part during the crushing process and discharge it out of the crushing container 7, and at the same time to discharge the sample discharged from the crushing container 7 out of the box body 1, the crushing container 7 is cylindrical, and the sieve plate 71 is fixedly installed on the lower part of the inner side wall of the crushing container 7. A cone-shaped discharge port is opened on the bottom inner wall of the box body 1 directly below the mounting plate 2.

[0054] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0055] Working principle:

[0056] First, the power is turned on. When the sample needs to be crushed, the sample to be processed is first placed in the crushing container 77, and then the crushing container 7 is locked in the tray 61. Then, the servo motor 601 is controlled by the controller to adjust the crushing container 7 to a position below the top cover 3. Then, the top cover 3 is controlled by the electric cylinder 31 to move downward and make the top cover 3 abut against the top of the crushing container 7. Then, the drive motor 4 is started. The output shaft of the drive motor 4 controls the fixed sleeve 42 to rotate through the telescopic square shaft 41. At the same time, under the cooperation of the drive gear 52 and the driven gear 51, multiple rotating shafts 5 are controlled to rotate, thereby controlling multiple crushing rods 501 and multiple crushing blades 502 to work together on the sample, thereby enabling efficient crushing. Since the crushing rods 501 and crushing blades 502 are staggered and arranged from top to bottom, the sample can be gradually refined to ensure the uniformity of the crushing effect. In addition, due to the setting of the sieve plate 71, the part that meets the particle size requirements can be discharged from the box 1 through the through port and the discharge port during the crushing process.

[0057] When it is necessary to inspect, maintain, or replace components such as the crushing rod 501 and the crushing blade 502, the top cover 3 is first moved upward by the electric cylinder 31, and then the worm gear 24 is driven to rotate by the adjusting motor 23. This allows the mounting plate 2 to be flipped under the action of the support shaft 21, thereby adjusting the crushing rod 501 and the crushing blade 502 to the position above the housing 1, greatly reducing the inconvenience of inspection, maintenance, and replacement operations.

[0058] During the crushing process, the relative position between the crushing container 7 and the rotating shaft 5 on the tray 61 can be adjusted as needed by the servo motor 601, thereby optimizing the material distribution during the crushing process. The rolling contact between the support wheel 62 and the inner wall of the bottom of the box 1 ensures the stability of the tray 61 during operation and avoids operational failures caused by equipment vibration or uneven load.

[0059] When the equipment is not in use, the two trays 6161 can be flipped upwards and fixed to the box 11 by magnetic blocks 6363, which effectively reduces space occupation and improves the space utilization rate of laboratory or industrial scenarios.

[0060] The above provides a detailed description of a high-efficiency pulverizing sample preparation pulverizer provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model.
