Under the drive of the speed reducing motor 26, the rotary feeding pipe 20 rotates around the circumference of the main shaft 23 at a uniform speed without stopping, and the feeding part 4 feeds materials to uniformly distribute the materials to the conical discharging cavities 10 uniformly distributed on the circumference.
As shown in FIG. 6, the rotary feeding pipe 20 comprises an inlet 201, an inclined section 202 and an outlet 203 which are connected in sequence, wherein the inlet 201 is arranged coaxially with the feeding part 4, and the central axes of the inlet 201 and the outlet 203 are arranged vertically. The inclined section 202 is arranged inclined downwards with respect to the inlet 201.
The shell 6 is arranged outside the rotary feeding pipe 20, and a second connecting flange 61 is arranged on the shell 6. The second connecting flange 61 on the cover 6 is bolted to the first connecting flange 110 on the barrel 11.

Because the connection between the adjacent conical discharging cavities 10 is only the thickness of the wall plate of the conical discharging cavity, namely the partition plate 12, and simultaneously has an ideal material self-flowing angle, the outlet of the rotary feeding pipe 20 at the side of the housing 6 forms an angle alpha so as to prevent the materials from accumulating at the inner side of the cylinder body of the conical discharging cavity 10 and directly throw the materials to the central position of the outlet of the discharging cavity 10. The outlet 203 of the rotary feeding pipe 20 on the side of the vertical shaft 23 forms an angle beta to avoid material accumulation on the supporting seat 13, and the material is directly fed to the central position of the outlet of the discharging cavity 10 to avoid residue and material accumulation.

a proximity switch is arranged near one of the high-pressure air source interfaces 33 and is connected with the PLC control unit 30 through a control line. The first and second bus windshield plates 31 and 32 are metal detection bodies. When the first and second confluence wind deflectors 31 and 32 are close to the induction area of the proximity switch, the proximity switch can send out an electric command rapidly without contact, pressure and spark, and accurately reflect the position and the stroke of the motion mechanism;
when the proximity switch is turned on and the feeding pipe 20 is detected to be rotated to the high-pressure air source interface 33, the PLC control unit 30 controls T0Opening the high-pressure air source interface electromagnetic valve at any moment, and controlling the electromagnetic valve to open for 1-3 seconds; according to the set main shaft rotating speed and the position of the high-pressure air source interface, the opening time T of one high-pressure air source interface is known0Opening time T of other i high-pressure air source interfacesiAnd T0Time difference Δ t therebetweeniIs calculable.

Because the connection between adjacent conical discharging cavities 10 is only the thickness of the wall plate of the conical discharging cavity, namely the partition plate 13, and simultaneously has an ideal material self-flowing angle, the outlet 203 of the rotary feeding pipe at the side of the housing 6 forms an angle alpha, and the material is directly thrown to the center of the outlet, so that the material accumulation at the inner side of the conical discharging cavity is avoided. The outlet 203 of the rotary feeding pipe on the main shaft side forms an angle beta, and the material is directly fed to the center of the outlet, so that the material is prevented from accumulating on the supporting seat 13.

The effective space distance between the first confluence wind boards 31 and the second confluence wind boards 32 on the two sides of the upper surface of the rotary feeding pipe 20 and the housing 6 is utilized to form waterfall type high-pressure airflow moving downwards along the housing 6, and the high-pressure airflow forms spiral waterfall type high-pressure airflow under the rotation of the rotary feeding pipe 20 to effectively clean the conical discharging cavities 101, 102 and 103, so that the conical discharging cavities 101, 102 and 103 of the conical discharging cavities are cleaned without residues.
