[0002] In biological experiments, sample grinding is usually involved, such as the plate colony count method to quantitatively detect the number of bacterial colonies in a sample. When conducting a bacterial counting experiment, the experimenter needs to grind the sample in a solution to obtain a bacterial suspension, and then dilute the bacterial suspension to an appropriate concentration with sterile water. Among them, the experimenter mainly uses a mortar and pestle to grind the sample. The mortar contains the sample and solution, and the pestle crushes and grinds the sample in the mortar by applying pressure and friction to grind the sample to the required fineness and obtain a grinding liquid.

[0003] However, when grinding samples such as tomato leaves, it is difficult for experimenters to grind the samples to a residue-free state. The sample residues remaining in the mortar are mixed in the grinding liquid, which can easily affect the subsequent operations of the experiment. Utility Model Content

[0032] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] Please see attached Figure 1-3 The plant grinding device of the utility model can be applied to biological experiments, such as bacteria counting or RNA extraction from plant tissues, and other experimental processes involving sample grinding. It can quickly separate the residue and grinding fluid in the grinding process to reduce the impact of the residue on subsequent experimental treatment of the grinding fluid.

[0036] Please see attached Figure 1 and attached Figure 2 The plant grinding device of the utility model comprises a mortar 1. Specifically, the mortar 1 is preferably, but not limited to, a ceramic mortar 1 or a stainless steel mortar 1. The mortar 1 comprises an inner bottom wall 11. A filtering structure 2 is arranged on the mortar 1, wherein the filtering structure 2 comprises a mortar cover 21 arranged on the mortar 1. The mortar cover 21 covers the opening of the mortar 1 to prevent the splashing of the sample. At the same time, the interior of the mortar 1 forms a sterile environment to a certain extent, reducing the influence of the external environment on the experimental results.

[0037] Combined with Figure 3 A fixing frame 22 is provided on the mortar cover 21. When the mortar cover 21 is closed on the mortar 1, the fixing frame 22 is located in the mortar 1. A filter bag 23 is sleeved on the outer side of the fixing frame 22. The fixing frame 22 presses the filter bag 23 on the inner bottom wall 11, and the filter bag 23 is fixed in the mortar 1. At this time, the sample can be ground in the filter bag 23. Specifically, the mesh number of the filter bag 23 can be selected according to the type of sample actually ground and the grinding fineness requirement.

[0038] A through hole 211 is formed through the mortar cover 21, and a pestle 3 is provided in the through hole 211 of the mortar cover 21. A gap is formed between the pestle 3 and the hole wall of the through hole 211, and the pestle 3 can rotate freely in the mortar 1. When grinding, the pestle 3 goes deep into the mortar 1 through the through hole 211, and the pestle 3 can crush the sample up and down, or rub against the filter bag 23 to grind the sample, so that the sample can be fully ground in the mortar 1.

[0039] Before grinding, the filter bag 23 is sleeved on the outside of the fixing frame 22, the mortar cover 21 is closed, and the filter bag 23 is fixed in the mortar 1 through the fixing frame 22. After the filter structure 2 is assembled, the sample is added to the mortar 1 through the through hole 211, and then the pestle 3 is extended into the mortar 1 through the through hole 211. The pestle 3 and the filter bag 23 on the inner bottom wall 11 rub against each other. The filter bag 23 can increase the roughness of the surface of the inner bottom wall 11, so that the sample is ground more fully. After grinding, the grinding liquid obtained by grinding the sample passes through the filter bag 23, while the residue remains in the filter bag 23. When the experimenter opens the mortar cover 21 and removes the filter bag 23, the residue and the grinding liquid are separated. When grinding different samples, different filter bags 23 can be replaced. Timely replacement of the filter bag 23 is conducive to reducing the possibility of sample contamination and experimental test results being affected due to incomplete cleaning of the filter bag 23.

[0040] Embodiment 2:

[0041] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the filter structure 2 of the utility model, see Figure 4~Figure 8 .

[0042] See also Figure 4 The fixing frame 22 of this embodiment includes a pressing ring 221, which is adapted to the mortar 1, and can increase the area where the filter bag 23 fits with the inner bottom wall 11, thereby expanding the grinding area of ​​the pestle 3. In some specific embodiments shown, the pressing ring 221 is a circular ring and fits with the annular inner wall of the mortar 1. Specifically, the fixing frame 22 includes a connecting rod 224, which is connected to the pressing ring 221. A plurality of connecting rods 224 can be provided, and the plurality of connecting rods 224 are distributed at intervals along the edge of the pressing ring 221. The connecting rod 224 assists in positioning the filter bag 23, and can cooperate with the pressing ring 221 to make the filter bag 23 fully fit with the inner wall of the mortar 1, thereby improving the stability of the fixing frame 22 when fixing the filter bag 23.

[0043] In a preferred embodiment, a side of the pressing ring 221 close to the inner bottom wall 11 of the mortar 1 is provided with an anti-slip point 222. Specifically, a plurality of anti-slip points 222 may be provided, and the plurality of anti-slip points 222 are spaced apart along the annular edge of the pressing ring 221. The anti-slip point 222 is preferably, but not limited to, a silicone anti-slip point 222. The silicone anti-slip point 222 facilitates the sterilization of the fixing frame 22 before reuse. The anti-slip point 222 may be cylindrical or circular convex, etc. It is understandable that this is not a specific limitation on the shape of the anti-slip point 222, and technicians in this field may replace it on this basis. The pressing ring 221 presses the filter bag 23 on the inner bottom wall 11 via the anti-slip point 222. The provision of the anti-slip point 222 can limit the movement of the filter bag 23, and further ensure the stability of the fixing of the filter bag 23 when the pestle 3 rubs the filter bag 23.

[0044] See also Figure 4~Figure 7 In a preferred embodiment, the fixing frame 22 includes a mounting ring 223, which is located at one end of the connecting rod 224 away from the pressing ring 221. The mortar cover 21 is provided with a mounting groove 213, which can be a ring-shaped groove. The mounting ring 223 is detachably connected to the mortar cover 21 in the mounting groove 213. In some specific embodiments, a clamping groove 214 is provided on the inner wall of the mounting groove 213, and a clamping protrusion 2231 is provided on the outer wall of the mounting ring 223. The clamping protrusion 2231 is specifically a ring-shaped convex strip. The clamping protrusion 2231 is clamped with the mortar cover 21 in the clamping groove 214. The clamping protrusion 2231 is clamped into the clamping groove 214, and the mounting ring 223 can be quickly assembled with the mortar cover 21, which has a simple structure and is easy to operate.

[0045] See also Figure 6 In some specific embodiments, the filter bag 23 is provided with a strap 231, which is tied to the fixing frame 22. The filter bag 23 can be initially fixed on the fixing frame 22, so that the fixing frame 22 can press and fix the filter bag 23 in the mortar 1. During assembly, the filter bag 23 is firstly bound to the fixing frame 22 by the strap 231, and the mounting ring 223 is clamped in the mounting groove 213. The fixing frame 22, the filter bag 23 and the mortar cover 21 can be assembled. Then, the mortar cover 21 is placed on the mortar 1, and the fixing frame 22 presses the filter bag 23 in the mortar 1. Specifically, a plurality of straps 231 can be provided, and those skilled in the art can select a corresponding number of straps 231 according to the specifications of the filter bag 23.

[0046] See also Figure 8 In other specific embodiments, the pestle 3 includes a grinding end 31, which rubs the sample on the filter bag 23 to grind the sample, and a convex pattern 32 is provided on the outer wall of the grinding end 31, and the convex pattern 32 cooperates with the filter bag 23 to grind the sample. Specifically, the convex pattern 32 is preferably, but not limited to, a cross-shaped protrusion, and the grinding end 31 can more fully grind the sample by rubbing against the filter bag 23 through the convex pattern 32 to ensure that the sample reaches the required fineness.

[0047] Embodiment 3:

[0048] The difference between this embodiment and embodiment 2 is that this embodiment further optimizes the structure of the fixing frame 22 of the utility model.

[0049] The mortar 1 of the present embodiment is provided with a fastening groove on the inner bottom wall 11. Specifically, the fastening groove can be an annular groove. A soft rubber pad is provided at one end of the pressing ring 221 close to the fastening groove. The pressing ring 221 presses the filter bag 23 into the fastening groove at the soft rubber pad. The soft rubber pad presses the filter bag 23 in the fastening groove and simultaneously has an interference fit with the fastening groove. The filter bag 23 is fixed in the mortar 1, and the filter structure 2 is easy to disassemble and assemble.

[0050] Embodiment 4:

[0051] The difference between this embodiment and the above embodiment is that this embodiment further optimizes the structure of the fixing frame 22 of the utility model, see Fig. 9 .

[0052] The mortar cover 21 of the present embodiment is threadedly connected to the mortar 1 , and the mortar cover 21 and the mortar 1 can be quickly assembled.

[0053] In a preferred embodiment, a liquid adding nozzle 24 for adding a solution to the mortar 1 is provided on the mortar cover 21. During the grinding process, the experimenter may add the corresponding solution while grinding. With the provision of the liquid adding nozzle 24, the experimenter can add the solution without opening the mortar cover 21, thereby reducing the possibility of sample contamination. A sealing sleeve 241 is provided on the outer side of the liquid adding nozzle 24. Specifically, the sealing sleeve 241 is preferably, but not limited to, a silicone sealing sleeve 241. After the solution is added, the sealing sleeve 241 seals the liquid adding nozzle 24, thereby preventing the liquid adding nozzle 24 from being contaminated during the assembly process of the mortar cover 21 and the filter structure 2.

[0054] In a preferred embodiment, a base 4 is sleeved on the outer side of the mortar 1, and a suction cup 41 for fixing the base 4 is provided on the base 4. When the base 4 is placed on the operating table, the suction cup 41 is fixed on the operating table by adsorption. In some specific embodiments, multiple suction cups 41 may be provided, and multiple suction cups 41 can maintain the balance of the placement of the base 4. When using a traditional mortar 1, the experimenter needs to hold the pestle 3 in one hand for grinding and fix the mortar 1 with the other hand. During the grinding process, the experimenter may slip, and the mortar 1 is difficult to be stably placed on the operating table. However, the present application is conducive to stably fixing the mortar 1 on the operating table through the provision of the base 4 and the suction cup 41, which is convenient for the experimenter to apply external force to the pestle 3.

[0055] In some specific embodiments, the mortar cover 21 is provided with an anti-collision rubber ring 212 in the through hole 211, and the outer wall of the anti-collision rubber ring 212 fits with the hole wall of the through hole 211. The pestle 3 passes through the anti-collision rubber ring 212 to extend into the mortar 1. The pestle 3 needs to be rotated when grinding the sample, and the pestle 3 is easy to collide with the mortar cover 21 in the through hole 211. The setting of the anti-collision rubber ring 212 can buffer the collision between the pestle 3 and the hole wall of the through hole 211, protect the pestle 3 and the mortar cover 21, and thus extend the service life of the pestle 3 and the mortar cover 21.
