[0028] The diameter of the buffer plate 2 is greater than the inner diameter of the feed pipe and the diameter of the positioning plate 3 .

[0029] In order to allow potassium fluoride to move smoothly downward in the receiving hopper, a plurality of mounting rods 5 are arranged around the circumference of the positioning plate 3. The mounting rods 5 are arranged transversely and their two ends are respectively fixedly connected to the positioning plate 3 and the hopper body 1. A plurality of hollow areas are arranged in the middle of the positioning plate 3.

[0030] The low-vibration receiving hopper also includes an anti-blocking mechanism, which includes an anti-blocking rod 6, which is arranged below the buffer plate 2, with the lower end of the anti-blocking rod 6 facing the outlet of the hopper body 1, and the diameter of the anti-blocking rod 6 is not greater than one third of the diameter of the outlet of the hopper body 1;

[0031] When the buffer tray 2 is located at the lowest position, the lower end of the anti-blocking rod 6 extends downwardly out of the outlet of the bucket body 1.

[0032] In order to make the anti-blocking rod 6 rotate continuously while moving back and forth longitudinally, the anti-blocking mechanism includes a screw sleeve 7, which is fixedly arranged in the middle of the positioning plate 3, the upper part of the anti-blocking rod 6 is threadedly sleeved in the screw sleeve 7, and the upper end of the anti-blocking rod 6 is rotatably arranged on the lower side of the buffer disk 2.
