[0024] The following is a detailed description of the specific implementation of the present invention with reference to the accompanying drawings.

[0025] Example:

[0026] The following is a specific embodiment of the sample receiving structure of a vacuum planetary mixer according to the present invention. Figure 1 It mainly includes a fixture 1 and a sample container 2. The fixture 1 is installed on the revolution plate a. The fixture 1 can be driven to revolve by the revolution plate a and can also rotate on its own. Figure 1 The specific installation structure of the middle clamp 1 on the revolution plate a and the driving structure of the revolution and rotation of the clamp 1 are not shown in the figure, and are all existing technologies.

[0027] The sample container 2 is detachably mounted in the fixture 1 and can revolve and rotate with the fixture 1, thereby stirring the sample contained therein.

[0028] Reference Figure 2 The specific structure of the clamp 1 is as follows: the clamp 1 includes a clamp body 101, and a container slot 102 is provided inside the clamp body 101. The container slot 102 extends downward from the top surface of the clamp body 101 to the bottom of the clamp body 101, and the top of the container slot 102 is connected to the outside. A short slot 103 and a long slot 104 are formed on the inner wall of the clamp body 101. The short slot 103 and the long slot 104 are respectively connected to the container slot 102. The height of the short slot 103 is less than the height of the container slot 102, and the height of the long slot 104 is the same as the height of the container slot 102. The tops of the short slot 103 and the long slot 104 are both connected to the outside.

[0029] The bottom of the fixture body 101 is provided with a first bearing 107, in which a stirring shaft 105 is rotatably mounted. The lower end of the stirring shaft 105 passes through the fixture body 101 and is fixedly connected to the revolving plate a. The upper end of the stirring shaft 105 extends to the bottom of the container slot 102 and is provided with a straight-line positioning block 106.

[0030] Reference Figure 3 The sample container 2 comprises a container body 201 and a container cover 202. The container body 201 and the container cover 202 are detachably connected, for example, by a threaded connection. A handle 209 is provided on the top of the container cover 202 to facilitate the removal of the sample container 2.

[0031] A positioning bar 203 is provided on the outer wall of the container body 201. The positioning bar 203 extends along the length of the container body 201 and is the same length as the container body 201. The positioning bar 203 can be inserted into the short slot 103 or the long slot 104, thereby placing the container body 201 at different depths within the container slot 102.

[0032] A sample storage chamber 204 is provided inside the container body 201, and the sample storage chamber 204 is used to hold the sample to be stirred. A concave cavity 205 is provided at the bottom of the container body 201, and the concave cavity 205 is formed by the bottom surface of the container body 201 being recessed upward. A second bearing 210 is provided in the container body 201 between the sample storage chamber 204 and the concave cavity 205, and a connecting shaft 206 is rotatably mounted in the second bearing 210. The upper end of the connecting shaft 206 is located in the sample storage chamber 204 and is connected to an agitator 207. The agitator 207 includes a connector 207a and a plurality of stirring blades 207b provided on the connector 207a. The connector 207a is detachably connected to the connecting shaft 206, for example, by a threaded connection, so that different agitators 207 can be replaced according to stirring needs. The lower end of the connecting shaft 206 is located in the concave cavity 205 and has a straight positioning groove 208. When the container body 201 is located at different depths, the straight positioning groove 208 can be used to separate or fit with the straight positioning block 106 to adjust the stirring force of the agitator 207.

[0033] Not shown in the figure, the clamp 1 and the sample container 2 can be locked by a locking bolt. The locking bolt can be installed on the clamp 1. After the sample container 2 is loaded into the clamp 1, the locking bolt can be screwed to fix the two to prevent the sample container 2 from loosening during rotation. After stirring is completed, the sample container 2 can be removed from the clamp 1 by screwing the locking bolt in the opposite direction.

[0034] When the utility model is in operation, when the sample needs to be stirred with a small force, refer to Figure 4 、 Figure 5, align the positioning strip 203 of the sample container 2 with the short slot 103 of the clamp 1 and insert it to the bottom. At this time, the sample container 2 has not been inserted to the bottom position of the clamp 1, and the stirrer 207 is in a free state. When the clamp 1 revolves and rotates, the sample container 2 is driven to revolve and rotate. Due to the existence of the stirrer 207, a certain relative movement will be generated between the sample container 2 and the sample contained therein, thereby generating a smaller stirring force on the sample.

[0035] When the sample needs to be stirred vigorously, refer to Figure 6 、 Figure 7 Align the positioning strip 203 of the sample container 2 with the long slot 104 of the fixture 1 and insert it fully into the fixture 1. At this point, the sample container 2 is fully inserted into the bottom position of the fixture 1. The straight-line positioning groove 208 at the lower end of the connecting shaft 206 can mate with the straight-line positioning block 106 at the upper end of the stirring shaft 105, thereby achieving a fixed connection between the stirrer 207 and the stirring shaft 105. Because the stirring shaft 105 is fixed to the revolving plate a, the stirrer 207 is also fixed. Therefore, when the sample container 2 revolves and rotates with the fixture 1, the sample container 2 also rotates relative to the stirrer 207, thus achieving sufficient stirring of the sample and greatly improving the mixing effect.

[0036] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any modifications based on the spirit of the main technical solution of the present invention shall be included within the scope of protection of the present invention.
