[0017] In order to make the material receiving plate 5 overturn, the mass of the material receiving plate 5 at one end above the support plate 7 is greater than that at the other end.
[0018] In order to balance the material receiving plate 5 during feeding, and not to affect the overturning of the material receiving plate when pouring down, a square groove is formed in one side of the pressing block 11, a sliding block 20 is slidably connected in the square groove through a second spring 19, a rhombus groove is formed in the sliding block 20, a connecting rod 21 is slidably connected in the rhombus groove, the other end of the connecting rod 21 is rotatably connected with the pressing block 11, a limiting block 22 is fixedly connected at the lower end of the sliding block 20, and the limiting block 22 is located above the lighter end of the material receiving plate 5.

In the process of the pressing block 11 falling, the limiting block 22 is extruded, the second spring 19 is contracted, the connecting rod 21 moves downward along the rhombus slot to the right side, until it enters the lowermost end of the rhombus slot, the second spring 19 is extruded, and is compressed under the constraint of the connecting rod 21 and the sliding block 20, so that the limiting block 22 is contracted and moves upward with the pressing block 11. At this time, the lighter end of the receiving plate 5 loses the limiting of the limiting block 22, and the receiving plate 5 tilts to the heavier end. In this process, the supporting plate 7 is subjected to a downward force and is offset under the action of the first spring 6, so that the receiving plate 5 is turned over until the lighter end of the receiving plate 5 contacts the pressing block 11. The extruded pharmaceutical intermediates are poured to pass through the first discharge pipe 3 into the auger conveying device 4, and then into the drying barrel 2. With the pressing block 11 moving downward again, the receiving plate 5 is reset, the limiting block 22 is extruded, and the connecting rod 21 moves upward along the rhombus slot to the left, until it enters the uppermost end of the rhombus slot. The second spring 19 loses the pressure of the constraint and expands, and at the same time, the limiting block 22 contacts the receiving plate 5 when the pressing block 11 moves upward, maintaining the balance of the receiving plate 15, waiting for the next input of the pharmaceutical intermediates. After the pharmaceutical intermediates enter the drying barrel 2, the motor 12 is started, driving the connecting rod 13 to rotate, and the cutter head 14 breaks the extruded pharmaceutical intermediates, and the heating rod 18 heats the pharmaceutical intermediates in the drying barrel 2. The water vapor generated in the process is discharged through the exhaust pipe 26, and the broken pharmaceutical intermediates are discharged through the second discharge pipe 17 under the action of the scraper 15 and the sieve plate 16.
