[0029] It should be noted that the transmission assembly 5 can drive the equalizing plate 4 to rotate forward and reverse. The equalizing plate 4 is provided with evenly distributed mesh holes. When the equalizing plate 4 rotates, the material can be evenly distributed, so that the material can be evenly put into the reactor.

[0030] Furthermore, the support platform 8 is a hollow cavity structure, a feeding port is provided on the support platform 8, a sealing strip (not shown in the figure) is provided on the sealing door 15, and each slide module 13 is provided with two slides with opposite moving directions.

[0031] In one embodiment of the present invention, Figure 3 As shown, the guide assembly 3 includes a connecting shaft 30, a second guide plate 31 and a spring 32, wherein the two ends of the connecting shaft 30 are respectively connected to the inner wall of the feeding box 1; the second guide plate 31 is sleeved on the connecting shaft 30; and the two ends of the spring 32 are respectively connected to the second guide plate 31 and the inner lower wall of the feeding box 1.

[0032] It should be noted that the second guide plate 31 described in this embodiment has meshes evenly distributed thereon, the second guide plate 31 is an L-shaped plate, and when the support roller is not in contact with the second guide plate 31, the end of the second guide plate 31 away from the discharge port 12 is higher.

[0033] Furthermore, the first guide plate 9 is disposed obliquely below the connecting shaft 30 , and when the spring 32 is in a natural state, the material on the second guide plate 31 will flow along the first guide plate 9 into the interior of the collecting box.

[0034] In one embodiment of the present invention, Figure 2As shown, the transmission assembly 5 includes a transmission shaft 50, a first gear 51 and a gear ring 52, wherein the transmission shaft 50 is rotatably arranged inside the shell 7; a through groove 60 is penetrated through the barrel 6, the first gear 51 is arranged on the transmission shaft 50, and the first gear 51 passes through the through groove 60 and is meshed and connected with the gear ring 52; a groove is provided on the inner wall of the barrel 6, the gear ring 52 is embedded and installed in the groove, and the gear ring 52 is arranged on the outer wall of the equalizing plate 4.

[0035] In the embodiment of the utility model, the transmission shaft 50 is connected to an external driving motor, which can drive the transmission shaft 50 to rotate, and through the cooperation of the first gear 51 and the gear ring 52, drive the dividing plate 4 to rotate forward and reverse.

[0036] Furthermore, if Figure 4 As shown, the two support shafts 10 are respectively provided with a second gear 16, and the two second gears 16 are meshingly connected. One of the support shafts 10 is connected to the motor. When the motor drives the support shaft 10 to rotate, the two second gears 16 cooperate to drive the two support shafts 10 to rotate in opposite directions.

[0037] In an embodiment of the utility model, the motor connected to the support shaft 10 is connected to a controller (not shown in the figure).

At the same time, the large particles or aggregated materials that are screened will fall on the second guide plate 31 along the inclined surface of the screening plate 2. When the screening plate 2 swings upward, the compressed spring 32 drives the second guide plate 31 to rotate upward, and finally makes the screened material on the second guide plate 31 slide onto the first guide plate 9, and finally discharged into the collection box.
