Description

Technical Field

[0001] This utility model relates to the field of testing and sample preparation technology, and in particular to a device for crushing and preparing fresh wolfberry samples for testing. Background Technology

[0002] In the testing of safety indicators such as pesticide residues and heavy metals in goji berry products, crushing and preparing fresh fruit samples is a crucial and indispensable pretreatment step. Due to the unique structure of fresh goji berries, the effective analytes are not uniformly distributed, and some may be concentrated under the peel or in the pulp. If the whole fruit is tested directly, the extraction solvent cannot fully contact all parts, resulting in extremely low extraction efficiency and severely distorted results that cannot represent the true safety status of the entire batch of samples. Crushing and preparing samples homogenizes the fresh fruit into a paste, greatly increasing the sample surface area and completely destroying the cell wall barrier. This allows the subsequently added extraction solvent to fully and rapidly penetrate the sample, thereby fully dissolving and extracting the target analytes and providing a highly homogeneous analyte solution for subsequent precision instrument analysis. When using existing equipment to crush and prepare samples of fresh wolfberries, the fresh fruit is usually put into a sample cup, the crusher is located directly above the sample cup, the crusher is started and it is put into the sample cup, thus completing the crushing and sample preparation of the fresh fruit in the sample cup. However, in actual use, after processing one set of fresh fruit, the user needs to clean the sample cup, refill it, and then fill it with the next set of fresh fruit before using the crusher to crush it. The cleaning and waiting process takes a long time, which reduces work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as high equipment idle rate, long waiting time for personnel, severely limited overall processing capacity, and low work efficiency, and to propose a testing device for crushing and preparing fresh wolfberry samples.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: Design a sample preparation device for crushing fresh wolfberry fruit for testing, including a base and a screw-locking assembly.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1

[0021] Reference Figure 1-5 This utility model is a testing device for crushing and preparing fresh wolfberry samples, including a base 1 and a screw-down locking assembly. The screw-down locking assembly includes a rotating shaft 2, which is rotatably connected to the base 1. An extension plate 3 is fixedly connected to the end of the rotating shaft 2. A vertical plate 4 is slidably connected to the extension plate 3. A crushing assembly is fixedly connected to the bottom surface of the vertical plate 4. A first round hole 6 and a second round hole 7 are sequentially opened on the vertical plate 4. An ear plate 8 is fixedly connected to the extension plate 3. An insertion rod 9 is slidably connected to the ear plate 8. A baffle 10 is fixedly connected to the periphery of the insertion rod 9. A first spring 11 is fixedly connected between the baffle 10 and the ear plate 8. The insertion rod 9 corresponds to the first round hole 6 and the second round hole 7. A plurality of placement slots 15 are evenly opened on the base 1. The crushing assembly includes a pressure cover 5, a pressure cover 4 and a vertical plate 4 are fixedly connected, a drive motor 12 is fixedly connected to the surface of the pressure cover 5, a rotating rod 13 is rotatably connected through the pressure cover 5, a number of crushing rods 14 are fixedly connected to the rotating rod 13, and the output end of the drive motor 12 is fixedly connected to the rotating rod 13.

[0022] The operation process of this embodiment is as follows: When in use, different groups of fresh fruit samples can be placed in different placement slots 15. Please refer to [link / reference]. Figure 2-3 In the initial state, the crushing rod 14 is located in the placement groove 15. At this time, the drive motor 12 drives the rotating rod 13 to rotate. The rotation of the rotating rod 13 drives the crushing rod 14 to rotate, thus crushing and preparing samples of the fresh fruit in the placement groove 15. After the fresh fruit in the placement groove 15 has been crushed, please refer to... Figure 5Pulling the insertion rod 9 causes it to exit from the second circular hole 7, at which point it contacts the limit of the vertical plate 4. Pulling the vertical plate 4 upwards moves the crushing rod 14 out of the placement slot 15. A servo motor 24 is fixedly connected inside the base 1, driving the rotating shaft 2 to rotate. The rotation of the rotating shaft 2 causes the extension plate 3 to rotate, allowing a cleaning station to be set on the base 1. The placement slot 15 in this station is not used for placing fresh fruit. The crushing rod 14 is then rotated into the cleaning station for cleaning. After cleaning, the servo motor 24 drives the rotating shaft 2 to rotate a certain angle, aligning the rotating rod 13 on the extension plate 3 with the next placement slot 15. Pulling the insertion rod 9 again... 9 is pulled out from the first round hole 6, and the vertical plate 4 is moved down until the insertion rod 9 is aligned with the second round hole 7. After the insertion rod 9 is released, the first spring 11 pushes the insertion rod 9 into the second round hole 7, thereby locking the position of the vertical plate 4. In this position, each crushing rod 14 is located in the placement slot 15. The drive motor 12 drives the rotating rod 13 to rotate, which can crush and prepare samples of fresh fruit at this position. By adjusting the position of the vertical plate 4 on the horizontal plate and adjusting the matching relationship between the insertion rod 9 and the first round hole 6 and the second round hole 7, fresh fruit can be placed in multiple placement slots 15 in advance. When in use, the crushing rod 14 can be quickly moved to the corresponding placement slot 15, thereby improving the working efficiency of crushing and preparing samples.

[0023] Example 2

[0024] For successful sampling, a crushing tube 16 is typically installed inside the placement trough 15. Fresh fruit is placed inside the crushing tube 16 for crushing. However, the crushing tube 16 is prone to shaking within the placement trough 15, thus reducing the practicality of the device. Therefore, please refer to... Figure 1-4 Based on the first specific embodiment, a crushing tube 16 is inserted into the placement groove 15. Several connecting plates 17 are fixedly connected to the base 1, and the connecting plates 17 correspond one-to-one with the placement groove 15. A square rod 18 is slidably connected inside the connecting plate 17. An arc-shaped abutment plate 19 is fixedly connected to the end of the square rod 18. A second spring 20 is fixedly connected between the arc-shaped abutment plate 19 and the connecting plate 17. A ring rail 21 is fixedly connected to the base 1. A round rod 22 is fixedly connected to the bottom surface of the extension plate 3. A slider 23 is fixedly connected to the end of the round rod 22. The slider 23 and the ring rail 21 are slidably engaged. The length of the rotating rod 13 is less than the height of the crushing tube 16. Pull rings 25 are fixedly connected to the ends of the square rod 18 and the insertion rod 9. The diameter of the pressure cap 5 is the same as the inner diameter of the crushing tube 16.

[0025] The operation process of this embodiment is as follows: When in use, pull the corresponding pull ring 25 on the square rod 18, thereby moving the square rod 18 and the arc-shaped abutment plate 19. At this time, insert the crushing tube 16 into the placement groove 15. After the crushing tube 16 is placed, the second spring 20 pushes the arc-shaped abutment plate 19 to press against the crushing tube 16, thereby preventing the crushing tube 16 from shaking during operation and further improving the practicality of the device. During operation, the crushing rod 14 is inserted into the crushing tube 16 to crush the fresh fruit. When the insertion rod 9 is inserted into the second round hole 7, the pressure cap 5 is just pressing against the top of the crushing tube 16, thereby preventing the fresh fruit from splashing during the crushing process. After the crushing and sample preparation is completed, when the crushing rod 14 moves to the next station, the crushing tube 16 can be pulled out from the placement groove 15 to proceed to the next testing process.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
