The appropriate type of grinder should be selected based on the properties of the sample and the required particle size.

[0003] While current technology offers many advantages, its disadvantages include incomplete sample pulverization, resulting in uneven particle size or failure to achieve the required fineness. This can affect subsequent experimental analysis results or product quality. Furthermore, the manual pouring of samples requires close contact between the operator and the equipment, increasing safety risks. Improper operation or negligence could lead to equipment malfunction or personal injury, posing significant safety hazards. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the process of crushing samples, incomplete crushing often occurs, resulting in uneven particle size or failure to achieve the required fineness, which may affect the accuracy of subsequent experimental analysis or the quality of the product. At the same time, when manually pouring samples, the operator has frequent contact with the equipment, which increases the safety risk. Improper operation or negligence may lead to equipment damage or personal injury, posing a significant potential danger.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a sample pulverizer, comprising a housing, wherein a support block one and a support block two are respectively installed on the outer wall of the housing, and a sieve plate is installed on the inner wall of the housing near the bottom, characterized in that it further comprises:

[0015] In a preferred embodiment, a second motor is mounted on the surface of the toothed plate, and the output end of the second motor passes through the toothed plate and is connected to a first rotating shaft. A first support plate is fixedly mounted on the surface of the first rotating shaft.

[0016] The technical effect of adopting the above-mentioned further solution is that by controlling the rotation of the shaft by the second motor, the support plate carrying the pallet is lifted to the height of the rectangular tipping opening, thereby achieving automatic tipping.

[0017] In a preferred embodiment, the flipping element includes:

[0018] A rectangular tilting opening is provided on one side of the box, and multiple limiting blocks are fixedly installed on the bottom inner wall of the rectangular tilting opening.

[0023] Motor 5 is fixedly installed on the top of the support block 2, and its output shaft is connected to gear 2;

[0024] The second rotating shaft is rotatably mounted inside the housing, and extends to both ends outside the housing, each equipped with a third gear.

[0025] The third gear is meshed with the second gear.

[0026] The technical effect of adopting the above-mentioned further solution is that the motor five drives the gear two to rotate, the gear two meshes with the gear three, thereby controlling the support plate two to flip and realize automatic flipping. At the same time, the rotating shaft two runs through the entire two sides of the box, ensuring that the support plates two on both sides of the box flip synchronously and avoiding the difference in flipping angle.

[0027] In a preferred embodiment, a support plate 2 is fixedly installed on one side of the gear 3, and a tray 2 is installed on the surface of the support plate 2.

[0028] The technical effect of adopting the above-mentioned further solution is that when the sample is assembled, the automatic tilting effect is achieved by the three pairs of pallets flipping through the gears.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example 1:

[0042] like Figure 3 and Figure 4 As shown in the figure, this embodiment provides a sample pulverizer that can achieve a lifting effect on samples. The specific idea is as follows:

[0043] To enable automatic vertical lifting of the sample, the sample pulverizer includes a housing 1, on which support blocks 306 and 103 are respectively installed. A sieve plate 4 is installed on the inner wall of the housing 1 near the bottom. The pulverizer also includes:

[0044] Motor 307 is fixedly installed on the top of support block 306, and gear 305 is fixedly installed on its output end.

[0045] The lifting component is installed on one side of the housing 1 and can move up and down vertically under the rotation of gear 305.

[0046] The lifting component includes a tray 311 for loading crushed samples. The tray 311 is located on top of the sieve plate 4, and a handle 312 is fixedly installed on one side of the tray 311.

[0047] The track column 303 has limit plates 302 fixedly installed at both ends, and the limit plates 302 are fixedly installed on the back of the box body 1.

[0048] Furthermore, it should be noted that the track column 303 includes, but is not limited to, shapes such as cylinders and cuboids. In this embodiment, a cylindrical structure is adopted, such as... Figure 3 As shown.

[0049] The toothed plate 304 is slidably disposed on the track column 303 and can move up and down in the vertical direction on the surface of the track column 303. A second motor 308 is installed on the surface of the toothed plate 304. The output end of the second motor 308 passes through the toothed plate 304 and is connected to a first rotating shaft 309. A first support plate 310 is fixedly installed on the surface of the first rotating shaft 309.

[0050] In this embodiment, after the first crushing is completed, the support plate automatically lifts the sample to the pouring port for a second pouring, thereby completing the second crushing. Through this automated process, the crushing efficiency is significantly improved, while reducing manual intervention and ensuring the accuracy of the crushing process. The automated lifting and pouring not only reduces the workload of operators, but also reduces the errors and safety hazards that may be caused by manual operation.

[0051] Example 2:

[0052] like Figure 1 and Figure 2 As shown in Example 1, this example also provides a sample pulverizer that can achieve a sample flipping effect. The specific idea is as follows:

[0053] In order to achieve the effect of automated sample dumping, the sample crusher includes: motor 104, which is fixedly installed on the top of support block 103, and gear 105 is fixedly installed at its output end.

[0054] The flipping component is installed on the other side of the housing 1 and can be flipped around the gear 105 as the axis under the rotation of the gear 105.

[0055] Motor 5 104 is fixedly mounted on the top of support block 2 103, and its output shaft is connected to gear 2 105.

[0056] The second rotating shaft 107 is rotatably disposed inside the housing 1, and both ends extend outside the housing 1 and are each equipped with a third gear 106.

[0057] Among them, the gear three 106 is meshed with the gear two 105, and a support plate two 101 is fixedly installed on one side of the gear three 106. A tray two 102 is installed on the surface of the support plate two 101.

[0058] In this embodiment, when pouring the sample, the sample can be placed on a tray first, and then automatically poured using a mechanical device. This automated pouring method reduces manual operation, improves work efficiency, and avoids sample waste or safety issues caused by human error. The tray design ensures that the sample remains stable and evenly distributed during the pouring process, thereby ensuring the smooth progress of the crushing process. Automated pouring can be optimized according to the characteristics of different samples, further enhancing the accuracy and stability of the production process. By introducing mechanized operation, not only is the process optimized, but the risks caused by manual intervention are also effectively reduced, improving operational safety and production efficiency.

[0059] Example 3:

[0060] like Figure 2 As shown, based on Example 1, this example also provides a sample pulverizer that can perform a secondary tilting effect after the sample is lifted. The specific idea is as follows:

[0061] A rectangular tilting opening 3 is provided on one side of the box body 1, and multiple limiting blocks 301 are fixedly installed on the bottom inner wall of the rectangular tilting opening 3.

[0062] It should be noted that the shape of the limiting block 301 includes, but is not limited to, cylinders, cuboids and other shapes. In order to ensure that the tray can be limited during tilting without obstructing the tilting of the sample, a triangular limiting block is used in this application.

[0063] Example 4:

[0064] like Figure 2As shown, based on Embodiment 1, this embodiment also has a motor 3 201 and a motor 4 202 fixedly installed on one side of the outer surface of the box 1. The output shafts of the motor 3 201 and the motor 4 202 both pass through one side of the box 1, and a rolling cylinder 2 is fixedly installed on the output shaft. Baffles 108 are installed on both sides of the inner wall of the box 1.

[0065] The forward and reverse rotation of motor 3 201 and motor 4 202 ensures more thorough crushing and grinding of the sample. At the same time, with the assistance of the baffle, the sample can be gathered between the two grinding cylinders.

[0066] Working principle:

[0067] Before operation, the sample to be crushed is placed on tray 2 102. After completion, motor 5 104 starts working, driving gear 2 105 to rotate. Since gear 3 106 meshes with gear 2 105, and two gears 3 106 are fixedly connected to both ends of shaft 2 107, the two support plates 2 101 on both sides rotate synchronously under the rotation of gear 3 106, thereby causing tray 2 102 to be flipped and lifted, and the sample begins to be poured out. At this time, motor 3 201 starts and begins to rotate forward, and motor 4 202 starts and begins to rotate in reverse, causing the two crushing cylinders 2 to begin to crush and crush the sample. The crushed sample falls from below the two crushing cylinders 2 into tray 1 311. At this time, manually grasp handle 312 and place tray 1 311 on support plate 1 310. At this time, motor 1 307 starts, driving gear 1 30 5. Rotation: Due to the meshing of the toothed plate 304 and gear 305, the toothed plate 304 rises slowly and uniformly under the rotation of gear 305. When the support plate 310 is aligned with the rectangular tilting opening 3, motor 307 stops working and motor 308 starts working, driving the rotating shaft 309 to rotate, which in turn causes the support plate 310 to flip. At this time, the sample in tray 311 is tilted again to the middle of the two crushing cylinders 2, realizing the secondary crushing and crushing process. The sample falls through the middle of the two crushing cylinders 2 to the sieve plate 4, and falls to the bottom of the box 1 after being screened by the sieve plate 4. After completion, motor 308 reverses, causing the support plate 310 to reset and stop. Motor 307 reverses, causing the support plate 310 to fall to the original height and stop working. Finally, motors 201 and 202 stop working.
