[0003] However, existing molecular biology experimental specimen grinding devices cannot pre-crush the specimens, resulting in poor grinding results in a single grinding operation. Therefore, they need to grind the experimental specimens multiple times to achieve a fine grinding result, which is inefficient. Utility Model Content

[0012] Preferably, the crushing mechanism includes two parallel crushing rollers that are rotatably connected to the crushing box via bearings. A second motor is installed on the outer wall of the crushing box. The shaft of the second motor is connected to one of the crushing rollers.

[0019] 3. Molecular biology experimental specimens are pulverized by two grinding rollers and then fed into a conical trough through a feeding box and feeding pipe to be ground into powder.

[0028] Example 1
[0029] A molecular biology experimental specimen grinding device, the structure of which is as follows: Figure 1-2As shown, the system includes a support platform 1, with support legs 2 at each of the four corners of the bottom of the support platform 1. A grinding table 3 is located in the middle of the upper part of the support platform 1. Four limiting wheels 8 arranged in a circular array on the upper surface of the support platform 1 and rolledly connected to the side wall of the grinding table 3 are provided. The limiting wheels 8 support the grinding table 3, making the grinding table 3 rotate more smoothly. A conical groove 4 is provided in the middle of the upper surface of the grinding table 3. A vertical plate 5 is provided on one side of the upper surface of the support platform 1, and a grinding rod 6 extending into the conical groove 4 is provided on the vertical plate 5. A drive mechanism for driving the grinding table 3 to rotate is provided on one side of the support platform 1. The drive mechanism includes a first motor 11, which is fixedly connected to the side wall of the support platform 1 through a motor frame. A pulley 9 is provided on the shaft of the first motor 11. An annular groove 7 is provided on the side wall of the grinding table 3, and a large pulley is provided in the annular groove 7. The pulley 9 and the large pulley are connected by a belt 10. By starting the first motor 11, the grinding table 3 is rotated under the action of the belt 10. When the material enters the conical groove 4, the grinding table 3 is rotating while the grinding rod 6 is stationary. Under the action of the conical groove 4, the material is squeezed up during the rotation and then automatically slides down. It is continuously squeezed between the grinding rod 6 and the grinding table 3, thereby realizing the pulverization of the material.
[0030] like Figure 1 and 3 As shown, the bottom inner wall of the conical groove 4 is provided with a plurality of uniformly and orderly distributed material leakage holes 18, and the interior of the grinding table 3 is provided with a conical cavity 21 at the bottom of the material leakage holes 18. The middle part of the bottom of the grinding table 3 is provided with a through hole 22 communicating with the conical cavity 21. The middle part of the surface of the support table 1 is penetrated by a discharge pipe 20. The top end of the discharge pipe 20 contacts the bottom of the grinding table 3, and the inner diameter of the discharge pipe 20 is larger than the diameter of the through hole 22. The material that is compressed into powder will enter the conical cavity 21 through the material leakage holes 18, and then enter the discharge pipe 20 through the through hole 22, and be discharged through the discharge pipe 20.
[0031] like Figure 1 and 4As shown, a crushing box 12 is provided above the grinding table 3, and a feeding box 13 is provided at the bottom of the crushing box 12. A feeding pipe 15 is provided in the middle of the bottom of the feeding box 13. The bottom of the feeding pipe 15 is located above the conical groove 4. Both sides of the bottom of the crushing box 12 are fixedly connected to the upper surface of the support table 1 by support rods. A feeding port 14 is provided at the top of the crushing box 12, and a crushing mechanism is provided inside the crushing box 12. The crushing mechanism includes two parallel crushing rollers 16 that are rotatably connected to the crushing box 12 by bearings. A second motor 17 is installed on the outer wall of the crushing box 12. The shaft of the second motor 17 is connected to one of the crushing rollers 16. The shafts of the two crushing rollers 16, away from the second motor 17, extend to the outside of the crushing box 12 and are connected by two gears 19. The two gears 19 mesh with each other. The crushing box 12 has a rectangular structure, and the feeding box 13 has a conical structure. By starting the second motor 17, the two grinding rollers 16 rotate simultaneously under the action of the two gears 19. This causes the molecular biology experimental specimens fed into the feed port 14 to be first crushed by the two grinding rollers 16, and then enter the conical groove 4 through the feed box 13 and the feed pipe 15 to be ground into powder. By crushing the material, it is easier to quickly grind it into powder later. This allows for finer, better, and more efficient grinding of the crushed specimen fragments.
[0032] Example 2
[0033] A molecular biology experimental specimen grinding device, with a structure basically the same as in Example 1, except that the feed tube 15 is an adjustable-length telescopic tube, and its structure is as follows. Figure 5 As shown, the feeding pipe 15 includes an outer pipe 151 fixedly connected to the top of the feeding box 13 and an inner pipe 152 sleeved inside the outer pipe 151; the outer pipe 151 has a hollow wall, and the top of the inner pipe 152 extends into the hollow wall and its outer peripheral wall is threaded to the hollow wall. In this embodiment, the feeding pipe 15 has a telescopic design that allows for length adjustment, which facilitates adjusting the distance between the feeding port and the grinding table 3 for different feeding amounts. This avoids the problem of feeding blockage caused by too short a distance and too much feeding, or the problem of the material not falling accurately to the vicinity of the grinding rod 6 for grinding due to too long a distance and too little feeding, thus ensuring a good connection between crushing and grinding operations. In addition, the hollow design of the outer tube 151 and the selection of the outer peripheral wall of the inner tube 152 to be threaded within the hollow tube wall can isolate the threaded connection structure from the feeding space, preventing material from adhering to the threaded connection structure during the feeding process and thus hindering the expansion and contraction adjustment of the feeding tube 15, thereby reducing the impact of the feeding operation on the expansion and contraction function of the feeding tube 15.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
