The mounting bracket 27 is fixedly arranged on the rotating shaft 22, and the driven wheel 25 is sleeved on the periphery of the mounting bracket 27 and is fixedly arranged. The driving motor 21 is fixedly arranged on the base 1, the rotating shaft of the driving motor 21 is vertically upward, the driving wheel 24 is fixedly arranged on the rotating shaft of the driving motor 21, and finally the synchronous belt 26 is wound on the driving wheel 24 and the driven wheel 25.

[0033] With reference to Figure 8 The stirring assembly 4 comprises a stirring handle 41 and four stirring blades 42. A rotation-preventing groove 412 is vertically formed in the center of the stirring handle 41. Correspondingly, a rotation-preventing table 222 is formed on the top end of the rotating shaft 22. One end of the rotating shaft 22 is clamped in the rotation-preventing groove 412, and the rotating shaft 22 drives the stirring handle 41 to rotate. The adjacent two stirring blades 42 are perpendicular to each other, and the end of one stirring blade 42 is fixedly connected with the middle position of the other stirring blade 42, so that the four stirring blades 42 are arranged to form a through groove 43.

When the stirring handle 41 rotates, the four stirring blades 42 rotate, so that the powder in the storage barrel 3 is moved and discharged from the discharge port 31 of the storage barrel 3.

[0034] With reference to Figure 9 and Figure 10The feeding assembly 5 comprises a feeding shaft 51, a driven gear 52, a fixing frame 53 and a discharge pipe 54. The fixing frame 53 is fixedly arranged on the base 1 and located at the bottom end of the discharge port 31. The feeding shaft 51 is horizontally rotatably arranged in the fixing frame 53. The feeding shaft 51 is composed of a rod body 511 and a carrier 512. The carrier 512 is located at the bottom end of the discharge port 31 and the peripheral side of the carrier 512 is in close contact with the inner side wall of the fixing frame 53. A plurality of feeding grooves 513 are formed on the surface of the carrier 512. The driven gear 52 is fixedly arranged at the end of the rod body 511 and in meshing engagement with the driving gear 23 of the driving assembly 2, so that the rotation shaft 22 is rotated to drive the feeding shaft 51 to rotate. The powder is discharged from the discharge port 31 of the storage barrel 3 and enters the feeding grooves 513 of the carrier 512. The driving motor 21 drives the rotation shaft 22 to rotate at a constant speed, so that the feeding shaft also rotates at a constant speed. In this way, the amount of powder entering the feeding grooves 513 each time is equal. The discharge pipe 54 is vertically arranged at the bottom end of the carrier 512 and fixed between the carrier 512 and the fixing frame 53. When the feeding grooves 513 containing powder are downward, the powder in the feeding grooves 513 falls into the discharge pipe 54 and is discharged.

[0035] With reference to Figure 11 and Figure 12 The receiving assembly 6 comprises a rotating motor 61 and a connecting rod 62. The rotating motor 61 is horizontally fixedly arranged at the bottom end of the base 1. One end of the connecting rod 62 is fixedly connected with the rotation shaft of the driving motor 21. A clamping groove 621 is formed at the end of the connecting rod 62 away from the rotating motor 61. A supporting ring 622 is arranged at the bottom end of the inner side wall of the clamping groove 621. The sample bottle is arranged in the clamping groove 621, so that the top end of the sample bottle is in abutment with the supporting ring. The rotation shaft of the rotating motor 61 is rotated, so that the sample bottle mounted on the connecting rod 62 is moved to the position directly below the discharge pipe 54. The powder discharged from the discharge pipe 54 falls into the sample bottle. After the powder is filled into the sample bottle, the rotation shaft of the driving motor 21 is rotated again until the sample bottle is moved out of the base 1. At this time, the sample bottle can be conveniently taken out of the clamping groove 621 of the connecting rod 62.

[0036] The specific implementation principle of the embodiment of the application is as follows: when it is needed to quantitatively add powder into a sample bottle, the sample bottle to be filled with powder is installed in the clamping groove 621 of the connecting rod 62, so that the top end of the sample bottle abuts against the support ring 622 in the clamping groove 621; the rotating shaft of the motor 61 is rotated to drive the sample bottle to move to the position directly below the discharge pipe 54. The powder to be added is added into the storage barrel 3; the powder in the storage barrel 3 is discharged from the discharge port 31 to the feeding groove 513 of the feeding shaft 51 under the action of gravity. The rotating shaft of the driving motor 21 is rotated to drive the rotating shaft 22 to rotate through the driving wheel 24, the driven wheel 25, the synchronous belt 26 and the mounting frame 27; the rotating shaft 22 drives the feeding shaft 51 to rotate through the driving gear 23 and the driven gear 52 in engagement during rotation. The uniform rotation of the feeding shaft 51 makes the feeding groove 513 filled with powder vertically downward, and the powder in the feeding groove 513 falls into the discharge pipe 54 under the action of gravity and then enters the sample bottle through the discharge pipe 54, so as to complete the quantitative addition of powder into the sample bottle.

[0037] During the rotation of the rotating shaft 22, the stirring handle 41 is simultaneously rotated to drive the stirring blades 42 to rotate during the rotation of the stirring handle 41; since the blade faces of the stirring blades 42 are downward and abut against the bottom end in the storage barrel 3, the stirring blades 42 drive the powder in the corners of the storage barrel 3 to move and be discharged from the discharge port 31 during the rotation, so as to avoid the accumulation of powder in the corners of the storage barrel 3.

[0038] The above has described the application by way of example in connection with the drawings, and it is obvious that the specific implementation of the application is not limited by the above mode, and various non-essential improvements or direct application of the technical scheme and concept of the application to other occasions without improvement are all within the protection scope of the application.
