[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the crushing device for a fully automatic liquid-based cell slide preparation machine provided by this utility model;

[0021] Figure 2 This is a schematic diagram of the internal structure of the processing box in this utility model;

[0022] Figure 3 This is a schematic diagram of the structure of the second and third moving parts in this utility model;

[0023] Figure 4 This is a schematic diagram of the drive component and the driven component in this utility model.

[0024] A crushing device for a fully automatic liquid-based cell preparation machine includes: a base plate 1, with wheels 2 at the bottom of the base plate 1; a push rod 3, a placement box 4, and a processing box 5 on the base plate 1; a rotatably connected sealing door 6 on the processing box 5; an extension plate 7 fixedly connected to the inner wall of the processing box 5; a first moving part 8 on the extension plate 7; a crossbar 9 on the first moving part 8; a second moving part 10 on the crossbar 9; a mounting plate 11 on the second moving part 10; a third moving part 12 on the mounting plate 11; a lifting seat 13 on the third moving part 12; a drive assembly 14 at the middle position of the lifting seat 13; a first crushing blade 15 fixedly connected to the output end of the drive assembly 14; driven assemblies 16 on both sides of the lifting seat 13; second crushing blades 17 fixedly connected to the driven assemblies 16; and a placement base 18 at the bottom of the processing box 5, with evenly distributed containers 19 inside the placement base 18.

[0025] The container 19 is transferred from the placement box 4 to the placement base 18, and the sealing door 6 is closed. The first moving part 8, the crossbar 9, the second moving part 10, the mounting plate 11, the third moving part 12 and the lifting seat 13 move continuously. The samples in each container 19 placed in the placement base 18 are processed by the drive assembly 14, the first crushing blade 15, the driven assembly 16 and the second crushing blade 17.

[0026] The first moving part 8 includes a first sliding rail 81, on which a first slider 82 is slidably connected. The crossbar 9 is fixedly connected to the first slider 82. The second moving part 10 includes a second sliding rail 101, on which a second slider 102 is slidably connected. The mounting plate 11 is fixedly connected to the second slider 102. The third moving part 12 includes a third sliding rail 121, on which a third slider 122 is slidably connected. The lifting seat 13 is fixedly connected to the third slider 122.

[0027] The first moving part 8 adopts a combination structure of the first sliding rail 81 and the first slider 82, which allows the crossbar 9 to move flexibly in the horizontal direction. Together with the second sliding rail 101 and the second slider 102 of the second moving part 10, it realizes the two-dimensional position adjustment of the mounting plate 11 in the vertical plane. Combined with the lifting function of the third sliding rail 121 and the third slider 122 of the third moving part 12, a precise positioning system in three-dimensional space is formed, which effectively expands the working coverage of the crushing blade.

[0028] The drive assembly 14 includes a motor mounting bracket 141, on which a drive motor 142 is mounted. The output end of the drive motor 142 is provided with a drive shaft 143. The drive shaft 143 passes through the lifting seat 13 to its lower part and is rotatably connected to it. The first crushing blade 15 is fixedly connected to the end of the drive shaft 143. A first bevel gear 144 is fixedly connected to the drive shaft 143.

[0029] The drive assembly 14 drives the drive shaft 143 through the drive motor 142 to rotate the first crushing blade 15. At the same time, the first bevel gear 144 is used to achieve power diversion. While ensuring the main blade cuts efficiently, it provides a synchronous power source for the driven assemblies 16 on both sides, thereby improving crushing efficiency and uniformity.

[0030] The driven component 16 includes a fixed base 161 and a vibrating rod 165. A driven shaft 162 is rotatably connected to the fixed base 161. A second bevel gear 163 and a cam 164 are fixedly connected to both ends of the driven shaft 162, respectively.

[0031] The first bevel gear 144 and the second bevel gear 163 rotate synchronously with the driven shaft 162 when the drive motor 142 starts.

[0032] The vibrating rod 165 is slidably connected to both sides of the lifting seat 13, the lower end of the vibrating rod 165 is fixedly connected to the second crushing blade 17, and the upper end of the vibrating rod 165 corresponds to the cam 164.

[0033] The driven component 16 adopts a linkage mechanism between the cam 164 and the vibrating rod 165 to convert the rotational motion into regular up-and-down vibration, so that the second crushing blade 17 forms a reciprocating impact crushing action, effectively avoiding the blockage problem caused by cell sample adhesion or accumulation.

[0034] A spring 166 is sleeved on the vibrating rod 165, and a limiting plate 167 is provided at the upper end of the vibrating rod 165. The limiting plate 167 is located on both sides of the cam 164.

[0035] The limiting plate 167 at the end of the vibrating rod 165 and the spring 166 form a double limiting protection. Together with the buffer structure of the spring 166, they form an elastic vibration system, which can limit the vibration amplitude to ensure operational safety and maintain the stability of the vibration frequency through the elastic reset function, thus extending the service life of mechanical parts.

[0036] The working principle of the crushing device of the fully automatic liquid-based cell preparation machine provided by this utility model is as follows:

[0037] The container 19 is transferred from the placement box 4 to the placement base 18, and the sealing door 6 is closed. The first moving part 8, the crossbar 9, the second moving part 10, the mounting plate 11, the third moving part 12 and the lifting seat 13 move continuously. The samples in each container 19 placed in the placement base 18 are processed by the drive assembly 14, the first crushing blade 15, the driven assembly 16 and the second crushing blade 17.

[0038] Compared with related technologies, the crushing device of the fully automatic liquid-based cell preparation machine provided by this utility model has the following beneficial effects:

[0039] The three-dimensional moving assembly, consisting of the first moving part 8, the second moving part 10, and the third moving part 12, ensures that the samples in each container 19 in the base 18 can be accurately positioned and processed. While the driving assembly 14 drives the first crushing blade 15 to operate, the driven assembly 16 also drives the second crushing blade 17 to vibrate up and down to assist in crushing and improve the crushing effect.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
