[0038] like Figures 1 to 9As shown, the utility model discloses a multifunctional sample divider, including a sample divider 1, a material outlet 12, a feed pipe 13 and a drive mechanism 14, as shown in FIG. Figures 1 to 3 As shown in the figure, the sample sub-body 1 has a conical structure, and the bottom of the sample sub-body 1 has a discard port 11; the conical structure here means that the main body of the sample sub-body 1 has a funnel-shaped structure, and the discard port 11 is arranged at the bottom to facilitate the sliding of discarded materials; in the embodiment of the present utility model, the discharge ports 12 are arranged in parallel on the side wall of the sample sub-body 1 in the circumferential direction, and a plurality of discharge ports 12 are provided; in the embodiment of the present utility model, the number of the discharge ports 12 can be set as needed; as Figure 3 As shown in , the feeding pipe 13 extends into the sample body 1, and the feeding pipe 13 is connected to the outside for inputting the sample to be sampled, and the feeding pipe 13 is arranged toward the discharge port 12; Figure 3 As shown in the figure, the feeding pipe 13 is arranged toward the discharge port 12, which means that the position of the outlet end of the feeding pipe 13 is adapted to the discharge port 12; when the feeding pipe 13 is rotated to the position of the discharge port 12, the material directly enters the discharge port 12 from the feeding pipe 13, and when the feeding pipe 13 is rotated to other positions of the sub-sample body 1, the material slides through the side wall of the sub-sample body 1 and slides from the discard port 11; in an embodiment of the utility model, the driving mechanism 14 is connected to the feeding pipe 13, and is used to drive the feeding pipe 13 to perform uniform reciprocating motion or intermittent reciprocating motion above the discharge port 12, or to perform intermittent reciprocating motion between the discharge port 12 and the discard port 11. It should be pointed out here that the uniform reciprocating motion corresponds to the equal distribution function, that is, the material is evenly distributed from the multiple discharge ports 12; and the intermittent reciprocating motion refers to quantitative sampling, that is, the feeding pipe 13 stays at each discharge port 12 for a set time; the intermittent reciprocating motion between the discharge port 12 and the discard port 11 corresponds to the reduction function, that is, the reciprocating motion is performed after staying at the discard port 11 for a set time. The range of the reciprocating motion here can include the discard port 11 or can only reciprocate at multiple discharge ports 12.

[0039] In the above embodiment, through the conical sample sub-body 1 and the discharge ports 12 circumferentially arranged in parallel on the side wall of the sample sub-body 1, the feeding tube 13 can realize the equal distribution function under the drive of the driving mechanism 14, that is, it performs a uniform reciprocating swinging action at each discharge port 12; through the discard port 11 set at the bottom of the sample sub-body 1, the shrinking function can be realized, that is, the feeding tube 13 performs a uniform reciprocating swinging action between the discard port 11 and the discharge port 12; in addition, the utility model can also perform quantitative sampling according to needs, that is, the feeding tube 13 sets the time at each discharge port 12 intermittently, so as to realize the quantitative sampling function; compared with the prior art, through the different actions of the feeding tube 13, a variety of sampling functions are realized, thereby improving applicability.

[0040] Alternatively, if Figures 3 to 5As shown in the figure, the discharge port 12 is a conical structure, the caliber of the outlet is smaller than the caliber of the inlet, and the inlet of the discharge port 12 is connected with the side wall of the sample object 1. In the embodiment of the utility model, 5 discharge ports 12 are provided, and those skilled in the art can provide more as needed; by providing the conical structure, it is possible to avoid the material from being stuck in the discharge port 12. In the embodiment of the utility model, the outlet of the discharge port 12 is used to connect an extension tube or a material receiving container. The end of the extension tube is then connected to the material receiving container, and the material receiving container here can be a bottle. By providing this structure, the placement of the material receiving container is more flexible.

[0041] Alternatively, if Figure 6 As shown in the figure, in order to better guide the discarded materials, the side wall of the sample body 1 is also provided with a guide groove 111, which is arranged on one side of the plurality of discharge ports 12, and is used to guide the discarded materials to the discarded material port 11. In the embodiment of the utility model, a receiving container is placed below the discarded material port 11, and the generated discarded materials can be collected below.

[0042] Optionally, the specific structure of the driving mechanism 14 is as follows: Figure 3 and Figure 4 As shown in the figure, the driving mechanism 14 includes a rotating seat 141 rotatably connected to the top of the sample object 1, the rotating seat 141 is hollow, the feeding tube 13 is fixedly connected to the rotating seat 141 and communicated with the hollow part; and also includes a rotating driving member 142 connected to the rotating seat 141 for driving the rotating seat 141 to rotate. The rotating driving member 142 here can be a servo motor, which can be connected to the rotating seat 141 through a synchronous belt or directly through gear meshing, so as to control the movement of the feeding tube 13.

[0043] Alternatively, if Figure 2 and Figure 3 As shown in the figure, in order to prevent the sample from adhering to the inside of the sub-sample body 1, a knocking mechanism 2 is also provided toward the sub-sample body 1, and the knocking mechanism 2 is used to knock the sub-sample body 1 to make the sub-sample body 1 vibrate. The knocking mechanism 2 here has a variety of structural forms, for example, it can be a cylinder or other conventional reciprocating mechanism. In some embodiments of the utility model, in order to make the discharge of the discharge port 12 more accurate, the knocking mechanism 2 is provided on a side close to the discharge port 12.

[0044] Optionally, in order to further clean the interior of the sample object 1, as Figure 3As shown in , it also includes a purge mechanism 3, which is arranged on the side of the sample sub-body 1 away from the discharge port 12, including a connection seat 31 fixed on the side wall of the sample sub-body 1, a gas nozzle 32 fixed on the outside of the connection seat 31 for connecting to the gas source, and a purge pipe 33 fixed inside the connection seat 31 and connected to the gas nozzle 32, and the purge pipe 33 is placed inside the sample sub-body 1. The gas source here can be an external high-pressure gas source. By blowing with high-pressure airflow, the inside of the sample sub-body 1 can be cleaned and the adhesion of the inner wall can be reduced; in addition, in the embodiment of the utility model, in order to further improve the comprehensiveness of cleaning, the purge pipe 33 is a soft pipe, and the purge pipe 33 produces a swinging action after being ejected by the airflow. The soft pipe here can be made of soft rubber; after the high-pressure airflow purge pipe 33 is ejected, it will force the purge pipe 33 to do irregular swinging action. By utilizing this phenomenon, the blowing of a single point can be upgraded to all-round cleaning, thereby improving the cleaning effect.

[0045] Alternatively, if Figures 7 to 9 As shown in the figure, the sample sample 1 also has a dust collection mechanism 4 disposed toward the discard port 11. The dust collection mechanism 4 includes a dust collector 41 and a telescopic drive member 42 for driving the dust collector 41 to approach or move away from the discard port 11. The telescopic drive member 42 here can be a cylinder. By arranging the dust collector 41 near the discard port 11, dust removal can be achieved. The dust collector 41 here can be connected to a dust collection pipe, which not only saves manpower but also avoids cross infection between samples.

[0046] Application scenario of an exemplary embodiment:

[0047] like Figures 1 to 9 As shown, when it is necessary to divide the sample equally, the driving mechanism 14 is controlled so that the feeding tube 13 only reciprocates between the set multiple discharge ports 12, and the time the feeding tube 13 passes through each discharge port 12 is the same, so that the amount of the sample flowing out is the same, achieving the effect of equal division; when it is necessary to divide the sample, a part of the sample can be discharged through the discard port 11 according to the setting, and then the remaining sample can be equally divided, or the amount of sample to be discharged can be calculated according to the setting, and then the feeding tube 13 can be evenly reciprocated at the discharge port 12 and the discard port 11; in order to explain clearly Quantitative sampling is further explained with an example below. When 10g of sample needs to be quantitatively sampled among three discharge ports, the three discharge ports are the first discharge port, the second discharge port and the third discharge port, the first discharge port requires 3g, the second discharge port requires 2g, and the third discharge port requires 5g. According to the amount required by each discharge port, the driving mechanism 14 is controlled to make the feeding pipe 13 reciprocate between the three discharge ports 12, and it will stay for different time periods when passing through the three discharge ports, so that the first discharge port obtains 3g, the second discharge port obtains 2g, and the third discharge port obtains 5g.
