[0009] A vibration driving mechanism is arranged in the machine case shell to drive the hollow plate to vibrate, and the vibrated hollow plate is reset through the elastic reset structure.
[0010] The drying mechanism is fixedly installed at the bottom of the cabinet shell and dries the material conveyed on the hollowed-out plate.
[0011] As an improvement, the drying mechanism comprises a hot air blower and a cloth air box; the cloth air box is fixed to the cabinet shell and covers the bottom opening of the cabinet shell, a plurality of uniformly distributed air outlets are arranged on the top wall of the cloth air box (each air outlet is arranged in a matrix shape along the top surface of the cloth air box), an air inlet is formed on the side, the hot air blower is fixedly installed outside the cabinet shell and connected to the air inlet through an air pipe.
[0012] As an improvement, the elastic reset structure comprises spring extension rods II and ear plates; the ear plates are connected to the four corners of the lower side of the hollowed-out plate through the spring extension rods II respectively, and the ear plates are integrally formed on the cabinet shell.
[0013] As an improvement, the vibration driving mechanism comprises a motor, a rotating shaft, a circular disc, spring extension rods I and knocking rollers; the rotating shaft is rotatably arranged between the opposite side walls of the cabinet shell, one end of the rotating shaft extends to the outside of the cabinet shell and is fixedly connected to the output shaft of the motor fixedly installed outside the cabinet shell, the circular disc is sleeved and fixed to the middle part of the rotating shaft, a plurality of spring extension rods I are fixedly connected to the side wall of the circular disc and uniformly arranged in the circumferential direction, the other end of each spring extension rod I is fixedly connected to a U-shaped roller support, and the knocking rollers are rotatably connected to the roller supports through shafts, and each knocking roller knocks the middle part of the hollowed-out plate in turn.
[0014] It is worth mentioning that the hot air blower and the motor used in the technical solution are existing devices in the prior art, and the use and control methods thereof are also existing technologies.
[0015] Compared with the prior art, the utility model has the advantages of:
[0016] 1. When the utility model is used, the drying mechanism dries the material conveyed on the hollowed-out plate, and in the process, the vibration driving mechanism can continuously knock the hollowed-out plate to make it vibrate frequently, so that the material can be conveyed more smoothly along the hollowed-out plate, and the phenomenon of material deposition during conveying is less likely to occur.

With the bottom of the housing 1 open, the perforated plate 2 is movably positioned inside the housing 1, and is clearance-fitted with the circumferential inner wall of the housing 1. The perforated plate 2 is inclined downwards from front to back. A feed inlet 3 is pre-reserved on the top wall of the housing 1 corresponding to the top of the perforated plate 2, and a discharge outlet 4 is pre-reserved on the side corresponding to the bottom of the perforated plate 2. The elastic reset structure includes a spring telescopic rod 12 and ear plates 13. Ear plates 13 are connected to the four lower corners of the perforated plate 2 via the spring telescopic rod 12, and the ear plates 13 are integrally formed on the housing 1.
[0028] like Figure 4 As shown, there are two guide baffles: 5 and 6. Both are integrally formed on the upper side of the perforated plate 2, and multiple of them are evenly arranged from front to back, while also being arranged alternately (both are also arranged perpendicular to the perforated plate 2). The guide baffle 5 only adheres to the inner wall of the housing 1 on the left side, and the guide baffle 6 only adheres to the inner wall of the housing 1 on the right side. Under the guidance of the guide baffles 5 and 6, the material on the top of the perforated plate 2 is conveyed backward and downward along a serpentine trajectory by gravity.
[0029] like Figure 5 As shown, the vibration drive mechanism includes a motor 14, a rotating shaft 15, a circular disc 16, a spring telescopic rod 17, and a striking roller 18. The rotating shaft 15 is rotatably disposed between the opposite side walls of the housing 1, with one end extending to the outside of the housing 1 and connected to the motor 14 which is installed and fixed on the outside of the housing 1. The circular disc 16 is sleeved and fixed in the middle of the rotating shaft 15, and multiple spring telescopic rods 17 are fixedly connected to the side wall and evenly arranged in the circumferential direction.
