The first and

second seats

40 and 50 are provided with the first convex profile 60 whose center is located on the rotation center line 11, however, in other embodiments, the first convex profile 60 may be formed by the first seat 40 or the second seat 50, and therefore, the invention is not limited thereto; and the particle ejecting bar 30 slides along the first convex profile 60 during the rotation of the turntable 10, so as to be driven by the first convex profile 60 to make telescopic sliding, as shown in fig. 3. For example, as shown in fig. 3, in the present embodiment, the first convex profile structure 60 is a convex profile groove and is located in the circular groove 41 along the radial direction of the rotary disk 10, the first convex profile structure 60 protrudes downward along the radial direction of the rotary disk 10, the first convex profile structure 60 drives the portion of the particle ejecting rod 30 located below the rotary disk 10 on the rotary disk 10 to perform telescopic sliding, that is, the particle ejecting rod 30 located at the lower left side in fig. 3 performs extending sliding under the driving of the first convex profile structure 60, and the particle ejecting rod 30 located at the lower right side in fig. 3 performs retracting sliding under the driving of the first convex profile structure 60, and the ejected particles 200 are more easily dropped under their own gravity, so that the transportation of the particles 200 is more reliable, but not limited by this example.

The second end of the switch structure 20 penetrates through the second end face of the rotary disk 10 and extends to the second disk seat 50, the second disk seat 50 is provided with a second convex profile structure 70, the wheel center of which is located on the rotation center line 11, preferably, the second convex profile structure 70 protrudes towards the second end face of the rotary disk 10 along the axial direction of the rotary disk 10, so that the switch structure 20 slides along the second convex profile structure 70 in the rotation process of the rotary disk 10, and is driven by the second convex profile structure 70 to open or close the radial particle conveying hole 13 to slide; for example, as shown in fig. 2, the second convex profile 70 is configured to drive the switch structure 30 below the rotary disk 10 to open the radial particle transporting hole 13, so as to allow the corresponding particle ejecting rod 30 to eject the particle 200 in the opened radial particle transporting hole 13, but not limited thereto.

During the rotation of the rotary table 10, the rotary table 10 selectively makes the inlet of the axial particle conveying hole 12 face or stagger with the discharge hole 43 to allow or prohibit the particles 200 in the discharge hole 43 to be ejected into the axial particle conveying hole 12 one by one, specifically, when the rotary table 10 makes the inlet of the axial particle conveying hole 12 face to the discharge hole 43 each time, there is a speed difference between the particles 200 in the discharge hole 43 and the particles 200 in the axial particle conveying hole 12, so that one particle 200 in the discharge hole 43 is ejected into the axial particle conveying hole 12, and the inlet of the axial particle conveying hole 12 can only be ejected into one particle 200 each time to face to the discharge hole 43, thereby realizing that the particles 200 in the first rotary table 40 are sequentially conveyed into the rotary table 10 one by one particle, but not limited thereto. The particle ejecting rod 30 ejects the particles 200 in the radial particle conveying holes 13 quantitatively under the driving of the first convex profile 60 and the cooperation of the second convex profile 70 driving the switch structure 20, as shown in fig. 3. It can be understood that, before the particle ejecting rod 30 ejects the particles 200 in the radial particle conveying hole 13, the switch structure 20 opens or closes the radial particle conveying hole 13 under the control of the second convex profile structure 70, and the particle ejecting rod 30 is under the control of the first convex profile structure 60, so that the particle ejecting rod 30 ejects the particles 200 in the radial particle conveying hole 13 under the coordination of the first convex profile structure 60, the second convex profile structure 70 and the switch structure 20. As shown in fig. 3, the first convex profile 60 protrudes downward along the radial direction of the rotary disk 10, and the second convex profile 70 protrudes toward the second end surface of the rotary disk 10 along the axial direction of the rotary disk 10, when the protrusion of the first convex profile 60 drives one particle ejecting rod 30 to protrude outward, correspondingly, the non-protrusion of the second convex profile 70 just contacts with the switch structure 20 matched with the particle ejecting rod 30 ejected from the protrusion of the first convex profile 60, and drives the switch structure 20 to open the radial particle conveying hole 13, so as to achieve the purpose that the particle ejecting rod 30 ejects the particle 200 in the radial particle conveying hole 13, as shown in fig. 3. More specifically, the following:

as shown in fig. 1 and 2, the discharge holes 43 are arranged in a circle at intervals along the circumferential direction of the circular groove 41, the centers of all the discharge holes 43 are located on the same circle, the center of the circle is located on the rotation center line 11, preferably, the center angle occupied by each discharge hole 43 is the same, and each discharge hole 43 is correspondingly provided with an axial particle conveying hole 12, a radial particle conveying hole 13, a switch structure 20 and a particle ejecting rod 30. Therefore, when the turntable 10 rotates for one circle, the discharge hole 43 can eject more particles 200 into the axial particle conveying hole 12, so that the conveying efficiency of the particles 200 can be further improved, but the invention is not limited thereto. For example, the diameters of the radial particle transporting hole 13, the axial particle transporting hole 12 and the discharging hole 43 are the same, so as to effectively avoid the joint of the radial particle transporting hole, the axial particle transporting hole and the discharging hole from affecting the reliability of transporting the particles 200 due to unevenness, but the invention is not limited thereto.

Meanwhile, the second end of the switch structure 20 is provided with the ball head structure 21, so that the sliding between the switch structure 20 and the second convex profile structure 70 is more reliable; it is understood that, in the normal state, the switch structure 20 is in the open state by means of a spring, but not limited thereto. The particle ejecting rod 30 comprises a radial rod section 31 and an axial rod section 32, the axial rod section 32 is in sliding fit with the first convex profile structure 60, the radial rod section 31 penetrates through the rotary table 10, and the axial rod section 32 drives the radial rod section 31 to perform telescopic sliding in the sliding process along the first convex profile structure 60. It should be noted that, since the first convex profile 60 is formed at the first seat 40 and the second seat 50, the axial rod segment 32 passes through the rotary disk 10 along the axial direction and both ends of the axial rod segment extend into the first convex profile 60 of the first seat 40 and the second seat 50, respectively, so as to ensure the reliability of the first convex profile 60 driving the particle ejecting rod 30 to perform the telescopic sliding, but not limited thereto.
