The separation structure 3 comprises a separation cavity 31 fixedly mounted on the longitudinal mounting plate 1, a plurality of independent cavities 32 are circumferentially distributed on the separation cavity 31 along a central axis of the conical cavity 21, a separation channel 33 used for communicating the concentration groove 23 with the independent cavities 32 is arranged on the independent cavities 32, and a separation door 34 is fixedly mounted at the top end of the separation channel 33. The separating door 34 is provided with a butt joint port 35, the butt joint port 35 is provided with a movable plate 37 which can slide linearly and reset through an elastic reset piece 36, the butt joint port 35 is internally nested with a butt joint body 38 which can slide longitudinally, the top end of the butt joint body 38 is jointed with the bottom end of the butt joint port 35 through a magnetic attraction component 39, the bottom end of the butt joint body 38 is fixedly connected with a flexible cavity 310, and one side of the butt joint body 38 is provided with a movable door 311 which is used for receiving and guiding extracting solution.

The abutment body 38 is mounted in the fractionating passage 33 so as to be linearly slidable and lockable, and the abutment body 38 is locked when the sample is not pulverized to a predetermined degree, which is achieved by another electromagnet.

When the sample is crushed to a preset degree, the butt joint body 38 is unlocked manually, so that the butt joint body 38 moves upwards under the mutual attraction of the magnetic attraction components 39, the butt joint body 38 extrudes the moving plate 37 of the butt joint port 35 to be opened, and the inner cavity of the butt joint body 38 is communicated with the concentration groove 23; and the sample powder flows into the interface 38.

The movable door 311 is designed similarly to the movable plate 38, and the movable door 311 can inject the extracting solution into the movable door 311 by inserting an external cannula.

When the sample powder received in the cavity of the docking body 38 reaches a certain weight, the magnetic force between the magnetic assemblies 39 cannot support the docking body 38 to attract, thereby causing the docking body 38 to slide downward.

Wherein, the magnetic attraction component 39 is composed of a pair of ring magnets respectively installed at the top end of the docking body 38 and the bottom end of the docking port 35. The ultrasonic structure 5 comprises a water containing tank 41 which is fixedly arranged on the longitudinal mounting plate 1 and is used for receiving the butt joint body 38 falling down and the flexible cavity 310, water bath liquid is filled in the water containing tank 41, the temperature of the water bath liquid is controlled by a temperature control assembly, and an ultrasonic generating assembly is arranged in the water containing tank 41; a channel for communicating the flexible cavity 310 is opened at the top end of the docking body 38, and an automatic control assembly 42 for automatically opening when the docking body 38 is docked with the docking port 35 and automatically closing when the docking body 38 is separated from the docking port 35 is installed in the channel.

When the docking body 38 slides down into the water containing trough 41, the ultrasonic vibration is transmitted to the flexible cavity 310 through the liquid, and the flexible cavity 310 is a light and thin flexible membrane, and the vibration can be transmitted to the liquid and powder in the flexible cavity 310.

The automatic control assembly 42 comprises a first conical body 421 fixedly sleeved in the channel, a second conical body 422 is arranged below the first conical body 421, the second conical body 422 is installed in the channel in a sealing manner through a sliding block 423 and can slide linearly, a sliding groove used for embedding the sliding block 423 is formed in the channel, two ends of the sliding groove are connected with the sliding block 423 through springs 424, and a pressing plate 425 used for being placed between the magnetic suction assemblies 39 is connected to the outer side of the sliding block 423; a plurality of first leakage grooves are uniformly formed in the second taper body 422 in the circumferential direction, and second leakage grooves, which have the same number as the first leakage grooves but are staggered in position, are uniformly formed in the first taper body 421 in the circumferential direction.

The second cone 422 part between the adjacent first leakage grooves is a radial rod-shaped connecting piece, the cross section of the rod-shaped connecting piece is triangular, the first cone 421 part between the adjacent second leakage grooves is another radial rod-shaped connecting piece, the cross section of the other rod-shaped connecting piece is triangular, the powder can conveniently slide down through the special shape of the rod-shaped connecting piece, and when the second cone 422 is tightly attached to the first cone 421 upwards, the other rod-shaped connecting piece just upwards props against the first leakage grooves, so that the flexible cavity 310 is closed, and the content in the flexible cavity 310 is prevented from leaking.

When the magnetic component 39 is mounted on the docking body 38, due to the dragging of the magnetic component 39, the driving platen 425 and the docking body 38 slide relatively, under the sliding action, the slider 423 slides the second cone 422 downwards, so that the self-control component 42 automatically forms an open state, and when the magnetic component 39 is separated, under the action of the spring 424 driving the slider 423, the second cone 422 is restored to be attached to form automatic closing.

Through above-mentioned device, can realize a plurality of samplings to a sample simultaneously, and ensure that the sample is even, and can a plurality of samples carry out different kinds of extractions simultaneously to carry out the supersound to a plurality of samples simultaneously, and guarantee each other noninterference between the various samples.

Thereafter, the contents of the flexible cavity 310 are manually extracted to be transferred to the detection device 10 for detection, and a corresponding effect is obtained.

The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
