Magnet bars 43 are fixed on both sides of the top of the supporting plates 42, and iron sheets are provided on both sides of the rocking table body 1. Magnetic attraction will be generated between the magnet bars 43 and the iron sheets, so that the supporting plates 42 can be stably placed in a vertical state. In this way, through the adsorption effect of the magnet bars 43, the supporting plates 42 can be adsorbed on one side of the rocking table body 1, thereby completing the storage operation of the cup-shaped module base 17 and the spring module base 19, reducing the space occupancy rate.

[0060] Example 2

[0061] refer to Fig.12 , improved on the basis of Example 1: the equipment also has the function of crushing solid raw materials, and a fixing rod 44 is fixed on the side of the two push plates 37 away from each other. The ends of the two fixing rods 44 away from the push plates 37 are sealed and slidably extended to the outside of the shaking table body 1, and a detachably connected U-shaped seat 45 is designed at the bottom of the fixing rod 44. The U-shaped seat 45 is located on the outside of the shaking table body 1, and a crushing wheel 46 for crushing the fixed raw materials is rotatably connected in the U-shaped seat 45.

[0062] Specifically, when it is necessary to prepare reagents and crush solid raw materials, the U-shaped seat 45 can be installed at the bottom of the fixed rod 44, the solid raw materials can be placed on the horizontally placed supporting plate 42, and then the shaking table body 1 can be started to shake. During the shaking process, the eccentric connecting rod 6 will drive the push plate 37 to reciprocate in a straight line. Due to the cooperation between the push plate 37 and the fixed rod 44, the operation of the push plate 37 will drive the crushing wheel 46 to rotate synchronously. In this way, the crushing wheel 46 can automatically crush the solid raw materials, realizing the multifunctionality of the equipment.

[0063] In summary, the laboratory modular mixing equipment not only has the function of mixing reagents, but also can realize the storage operation of the reagent base through the rotation of the supporting plate 42 and the adsorption effect of the magnet bar 43, thereby reducing the space occupancy rate. At the same time, the equipment also has the function of crushing solid raw materials. By installing the U-shaped seat 45 and the crushing wheel 46, the automatic crushing operation of the solid raw materials can be realized, thereby improving the versatility and practicality of the equipment.

[0064] A method for using a modular mixing device for a laboratory comprises the following steps:

[0065] S1. When performing circular oscillation and shaking, multiple reagent bottles are placed in the sample fixing cup 18 respectively, the oscillating body 7 is placed on the pad 11, the top of the eccentric connecting rod 6 passes through the circular oscillation hole 8, and multiple rectangular plugs 13 are respectively inserted into the rectangular slots 12 to fix the oscillating body 7, the eccentric connecting rod 6 and the fixing rod 44. Then, the oscillating body 7 and the eccentric connecting rod 6 are further fixed by tightening the bolts 14, and then the cross plug 15 at the bottom of the cup-shaped module base 17 is inserted into the cross slot 10, and the magnet block 16 is connected to the cross slot. The iron layer in 10 can adsorb the cross plug 15 on the top of the oscillating body 7, and the eccentric connecting rod 6 is driven to rotate by the driving motor 5. The eccentric connecting rod 6 drives the cup-shaped module base 17 to revolve through the oscillating body 7 and rotates at the same time, thereby completing the circular oscillation and shaking. During the shaking, the support plate 21 is located at the bottom of the oscillating body 7 to support the oscillating body 7; similarly, the spring module base 19 can be installed on the top of the oscillating body 7 through the cooperation of the cross plug 15 and the cross slot 10, so that reagent bottles of different shapes can be placed;

[0066] S2. When reciprocating oscillation is performed, the eccentric connecting rod 6 is inserted into the reciprocating oscillation bar hole 9, the pad 11 supports the oscillating body 7, and a rectangular plug 13 away from the center of the circle is just placed in the adjacent slide groove 22, and the slide groove 22 cooperates with the rectangular plug 13, and then the spring module base 19 or the cup module base 17 is installed on the oscillating body 7 as needed, and the eccentric connecting rod 6 is driven to rotate by the driving motor 5. The cooperation between the eccentric connecting rod 6 and the reciprocating oscillation bar hole 9 can drive the oscillating body 7 to reciprocate and run in a straight line, thereby performing a reciprocating oscillation and shaking operation;

[0067] S3. In addition, when performing the shaking operation, the reagent to be shaken can be subjected to a water bath and an air bath as needed; when performing the air bath, the connecting end 25 and the air bath module body 24 are inserted into the connecting port 23, and the first tension spring 35 exerts a pulling force on the trapezoidal plug rod 36, and the inclined surface of the trapezoidal plug rod 36 cooperates with the right-angled side of the trapezoidal fixing strip 32 to tightly fit the air bath module body 24 to one side of the shaking table body 1, so that the connecting end 25 can seal the connecting port 23, and the first temperature detection head 27 and the fan 26 extend into the shaking bin 3, and the fan 26 turns the heating plate 28 to the heating plate 28. The heated air is discharged into the shaking bin 3 for air bathing the reagent, and at the same time, the first temperature detection head 27 monitors the temperature in the shaking bin 3 in real time and displays it on the display screen on one side of the air bath module body 24; when a water bath is performed, the connection end 25 and the water bath module body 29 are inserted into the connection port 23, the connection end 25 seals the connection port 23, and clean water is injected into the shaking bin 3, which is heated by the heating rod 30, and the second temperature detection head 31 monitors the water temperature in the shaking bin 3 in real time, and displays it on the display screen on one side of the water bath module body 29, so that the reagent can be water bathed;

[0068] S4. When performing a water bath or an air bath, the eccentric connecting rod 6 drives the cup-shaped module base 17 or the spring module base 19 to perform a shaking operation. At this time, the eccentric connecting rod 6 drives the push plate 37 to move back and forth in a straight line through the cooperation of the pull rope 38 and the rotating ring 39. The movement of the push plate 37 can stir the water or air in the shaking bin 3, so as to evenly distribute the hot water or hot air in the shaking bin 3, so as to facilitate the shaking of the reagent;

[0069] S5. In addition, when the carrying plate 42 is kept in a horizontal state, the spring module base 19 or the cup-shaped module base 17 can be placed on the carrying plate 42 for placing the reagent. After the shaking is completed, the cup-shaped module base 17 and the spring module base 19 are placed on the two carrying plates 42 respectively, and the carrying plate 42 is pushed to rotate. The carrying plate 42 is adsorbed on one side of the shaking table body 1 through the magnet bar 43, and the storage operation of the cup-shaped module base 17 and the spring module base 19 can be completed, thereby reducing the space occupancy rate;

[0070] S6. When preparing reagents, solid raw materials need to be crushed. At this time, the U-shaped seat 45 is installed at the bottom of the fixed rod 44, and the solid raw materials are placed on the horizontally placed supporting plate 42. As the eccentric connecting rod 6 rotates, the eccentric connecting rod 6 drives the push plate 37 to reciprocate in a straight line. The cooperation between the push plate 37 and the fixed rod 44 can drive the crushing wheel 46 to run synchronously. The crushing wheel 46 can automatically crush the solid raw materials, and the functions are complete.

[0071] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 5, heating rod 30, second temperature detection head 31, heating plate 28, fan 26 and first temperature detection head 27 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art can make any optional selections according to their needs or convenience.
