The fixed part of the first driving member 23 is fixedly arranged at the bottom of the vertical conveying pipe 21. The driving shaft of the first driving member 23 penetrates through the vertical conveying pipe 21 and is fixedly connected with the bottom end of the spiral conveying rod 22.

The input end of the conveying pipe 32 is fixedly arranged on the sleeve pipe 31. The fixed part of the elastic supporting member 33 is fixedly arranged on the vertical conveying pipe 21. The telescopic part of the elastic supporting member 33 is fixedly connected with the sleeve pipe 31.

The first bevel gear 41 is fixedly arranged at the top end of the spiral conveying rod 22. The first rotating shaft 42 penetrates through the vertical conveying pipe 21 and is rotatably connected. The second bevel gear 43 is fixedly arranged at one end of the first rotating shaft 42. The second bevel gear 43 is in meshing engagement with the first bevel gear 41. The cam 44 is fixedly arranged at the other end of the first rotating shaft 42. The surface of the cam 44 abuts against the top of the sleeve pipe 31. The input end of the conveying pipe 32 is in communication with the discharging port 211 through the sleeve pipe 31.

[0025] In the embodiment, the first driving member 23 is a motor structure, which is convenient for directly driving the spiral conveying rod 22 to stably rotate and adjust in the range of the vertical conveying pipe 21.

[0026] In the embodiment, the feeding port 210 is aligned with the material storage range of the material box 1. The material box 1 is pre-injected or continuously injected with the medicinal material to be conveyed, so as to facilitate the transmission and feeding of the subsequent medicinal material.

[0027] The elastic supporting member 33 is a spring supporting pipe structure, which is used for providing the sleeve pipe 31 with upward elastic force, so that the top of the sleeve pipe 31 can maintain abutment with the cam 44.

Similarly, when the cam 44 continues to rotate, the convex part of the cam 44 gradually contacts the sleeve 31, after the contact, the convex part of the cam 44 abuts the sleeve 31 to move down, the elastic support 33 is compressed and shrunk under the pressure action of the sleeve 31, until the convex part of the cam 44 completely abuts on the sleeve 31, and the sleeve 31 and the conveying pipe 32 are maintained in the down-moving state. Through the reciprocating, in the process of continuous rotation of the cam 44, the conveying pipe 32 is driven to adapt to the up-and-down vibration, which provides vibration support for the stable discharge of the material into the conveying pipe 32.

[0029] The vertical conveying pipe 21 is connected to the material box 1 in a vertical installation manner, which reduces the floor area occupied by the equipment during installation and use, and reduces the required activity space during movement and adjustment. When the first driving member 23 drives the screw conveying rod 22 to rotate, the screw conveying rod 22 drives the material entering the range of the vertical conveying pipe 21 to be conveyed upward, at the same time, the screw conveying rod 22 drives the first bevel gear 41 to rotate, the first bevel gear 41 drives the second bevel gear 43 to rotate, and the first rotating shaft 42 drives the cam 44 to rotate synchronously, so that the cam 44 rotates to press the sleeve 31, under the elastic support action of the elastic support 33, the sleeve 31 drives the conveying pipe 32 to vibrate up and down, so as to facilitate the vibration discharge of the conveying pipe 32, and the material entering the conveying pipe 32 is stably discharged under the vibration action.
