[0037] like Figures 1-5 As shown, this utility model provides a device for preparing DNA ploidy staining stock solution, including: a grinding and filtering component 1, a storage component 2, and a delivery component 3;

[0038] The grinding and filtering assembly 1 includes a housing 10, inside which is an inner housing 11. A gravity sensor 12 is connected between the lower end of the inner housing 11 and the inner bottom of the housing 10. By directly placing the raw material into the inner housing 11, the gravity sensor 12 weighs it, eliminating the need for material transfer, reducing material loss, and lowering the risk of accidents. A grinder 13 is connected to the top of the inner housing 11, used for grinding and mixing the raw material. A filter 14 is located at the lower end of the housing 10, and a conduit 15 connects the filter 14 to the inner housing 11. The mixed solution enters the filter 14 through the conduit 15, allowing the filter 14 to filter the solution and remove impurities and undissolved anthraquinone powder. A support 16 is provided on the outer surface of the housing 10; the support 16 supports the entire grinding and filtering assembly 1.

[0039] The storage component 2 includes a material box 20 and an alcohol container 21 located at both ends of the outer casing 10. The material box 20 is used to store thion powder, and the alcohol container 21 is used to store 50% ethanol.

[0040] The conveying assembly 3 is used to convey the raw materials in the material box 20 and alcohol barrel 21 to the inner shell 11.

[0041] In one embodiment, please refer to Figures 2-3 The grinder 13 includes a motor 130. The output end of the motor 130 passes through the top of the inner shell 11 and is connected to a guide rail 131. The lower end of the guide rail 131 is provided with a groove 132. An electric push rod 133 is connected to the inner wall of the groove 132. The telescopic end of the electric push rod 133 is connected to a slider 134 that matches the groove 132. The lower end of the slider 134 is elastically connected to a grinding pestle 135. After the raw materials are added, the motor 130 is started, which drives the guide rail 131 to rotate. The guide rail 131 further drives the grinding pestle 135 to rotate through the slider 134. At the same time, the electric push rod 133 is started, which pushes the slider 134 to move left and right along the groove 132 in the guide rail 131, thereby controlling the movement range of the grinding pestle 135 and achieving the effect of effective grinding within the inner shell 11.

[0042] In one embodiment, please refer to Figures 2-3 The upper end of the guide rail 131 is rotatably connected to the inner top of the inner shell 11; the inner shell 11 supports the guide rail 131. The slider 134 is slidably connected to the grinding pestle 135, and a spring 136 is sleeved on the outer surface of the connection. The grinding pestle 135 is smaller at the top and larger at the bottom, and the outer edge of the bottom is an inclined arc surface. When the grinding pestle 135 encounters an obstacle, the arc surface at the bottom changes the direction of the resistance, compresses the spring 136, causes the spring 136 to contract, and drives the grinding pestle 135 to rise, thereby avoiding the obstacle and extending the service life of the grinder 13.

[0043] In one embodiment, please refer to Figure 4The filter 14 includes a filter cylinder 140, inside which a filter screen 141 is provided, and the lower end of the filter cylinder 140 is connected to a discharge port 142. The mixed solution is transported into the filter cylinder 140 by a conduit 15, and impurities and undissolved thion powder are filtered out by the filter screen 141. The filtered solution is discharged from the discharge port 142 for collection.

[0044] In one embodiment, please refer to Figure 4 The filter cartridge 140 includes an upper cover 1400 connected to the conduit 15. A rotating ring 1401 is threadedly connected to the lower end of the upper cover 1400. The rotating ring 1401 is detachably connected to the filter screen 141. The lower end of the rotating ring 1401 is threadedly connected to a lower cover 1402. By threading the two ends of the rotating ring 1401 to the upper cover 1400 and the lower cover 1402 respectively, it is easy to disassemble and clean, and it is also convenient to remove the filter screen 141 for cleaning and replacement.

[0045] In one embodiment, please refer to Figure 1 The support 16 includes a collar 160 surrounding the outer surface of the housing 10, one end of which is connected to a support column 161, and the lower end of the support column 161 is connected to a base 162. The support 16 can support the entire grinding and filtering assembly 1.

[0046] In one embodiment, please refer to Figure 1 and Figure 4 An electric telescopic rod 144 is connected between the lower middle part of the outer casing 10 and the upper middle part of the upper cover 1400. The electric telescopic rod 144 is used to control the up and down movement of the filter 14. This causes the outlet 142 of the filter 14 to move downward and insert into the mouth of the collection bottle, preventing solution leakage.

[0047] In one embodiment, please refer to Figure 1 The upper end of the base 162 is located directly below the filter 14 and has a groove 163. The groove 163 is used to place the external collection bottle so that the collection bottle is located directly below the filter 14. It should be noted that the bottom shape of the collection bottle matches the groove 163 and can be customized according to the actual situation.

[0048] In one embodiment, please refer to Figure 1 and Figure 5The conveying assembly 3 includes an inclined conveying pipe 30 connected to the bottom of the material box 20. The other end of the inclined conveying pipe 30 passes through the outer shell 10 and connects to the top of the inner shell 11. A second motor 31 is connected to the bottom of the conveying pipe 30. The output end of the second motor 31 extends into the conveying pipe 30 and is connected to a spiral conveying roller 32. In use, the second motor 31 is started, and the second motor 31 drives the spiral conveying roller 32 to rotate. The spiral conveying roller 32 conveys the anthurium powder flowing out of the material box 20 from the lower end to the inner shell 11. Because the conveying pipe 30 is inclined, the conveying can be stopped in time after the specified weight is reached, preventing the anthurium powder from continuing to discharge due to its own gravity, thus improving the accuracy of the discharge.

[0049] In one embodiment, please refer to Figure 1 and Figure 5 The delivery assembly 3 also includes a pump body 33 connected to the alcohol tank 21. The output end of the pump body 33 is connected to a water pipe 34, the other end of which passes through the outer shell 10 and connects to the inner shell 11. A metering valve 35 is installed on the water pipe 34. During use, based on the weight detected by the gravity sensor 12, the required proportion of 50% ethanol is calculated. The pump body 33 is then activated, drawing 50% ethanol solution from inside the alcohol tank 21 and delivering it to the inner shell 11 through the water pipe 34. During delivery, the metering valve 35 measures the amount of 50% ethanol solution, facilitating the direct and rapid delivery of the specified weight, thus improving preparation efficiency and accuracy.

[0050] The specific usage process of this utility model is as follows: Based on actual needs, a corresponding weight of raw material is determined. Motor 31 is started, driving the spiral conveyor roller 32 to rotate. The spiral conveyor roller 32 tilts and conveys the anthurium powder flowing from the material box 20 upwards into the inner shell 11. The gravity sensor 12 at the lower end of the inner shell 11 weighs the anthurium powder. After reaching the specified weight, motor 31 is turned off to stop the conveying of the anthurium powder. Pump 33 is then started, drawing 50% ethanol solution from the alcohol tank 21 and conveying it to the inner shell 11 through the water pipe 34. Simultaneously, a metering valve 35 is used for metering to ensure accurate dispensing. After both the anthurium powder and the 50% ethanol solution have been conveyed into the inner shell 11, the grinder 13 is started to grind and mix the raw materials. The uniformly mixed solution is conveyed to the filter 14 through the conduit 15, filtered by the filter 14, and finally flows into a collection bottle for storage and use.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
