Disclosed is an epicyclic gear. A body with a plurality of workpiece holes is arranged inside, and elastic connecting bodies are arranged on the walls of the workpiece holes, extend out of bodies of the workpiece holes, are of the same structure and are arranged sequentially, symmetrically and evenly. Compared with the prior art, after the elastic connecting bodies are additionally arranged, rigid contact and point contact of the hole walls of the epicyclic gear and workpieces are converted into an elastic body and face contact relation, and the effects that a piano key type structure contains the workpieces and interacts with the workpieces are achieved. On one hand, the elastic connecting bodies are in contact with the workpieces, so that acting force of the workpieces is effectively released. On the other hand, the workpieces are borne by the epicyclic gear during revolution and rotation, especially when special-shaped workpieces are machined, point contact is firstly achieved, then the peripheral stressed elastic connecting bodies gradually bear pressure to support the workpieces along with increase of workpiece extrusion force, point contact is converted into face contact, and the extrusion force is gradually dispersed. Breaking points, cracks, broken sheets and bright points are avoided, and the problems that thin workpieces and special-shaped workpieces are low in yield and hard to machine are solved.

The invention discloses an automatic shifting device. The automatic shifting device comprises a rack; a conveyor line is arranged on the rack; one side of the rack is provided with a first shift piecedevice; the first shift piece device comprises a first electric cylinder, a first sliding rod, a first shift piece, a first reset spring, a first rotating shaft and a first L-shaped frame; an outputshaft of the first electric cylinder and a first sliding rod shaft are connected to a first connecting block; the first shift piece is fixed on the rack through the first rotating shaft and can rotatefreely around the first rotating shaft; the first L-shaped frame is fixed on the first sliding rod shaft and can move horizontally with the first sliding rod; the first L-shaped frame is in point contact with the end face of the first shift piece; one end of the first reset spring is fixed on a second bracket and the other end of the first reset spring is fixed on the first shift piece; when thefirst shift piece rotates around the first rotating shaft, the first reset spring is pulled up to be in a state of tension; and a jacking plate is arranged in the middle of a conveying roller at the tail end of the transmission direction of the conveyor line, and a jacking cylinder is arranged at the bottom of the jacking plate.

The invention provides a multi-point real-time parameter monitoring and transmitting system of a drum-type traditional Chinese medicine pill dryer. The multi-point real-time parameter monitoring and transmitting system comprises a base and a roller, a transmitter is arranged on the outer wall of the roller, a first starting contact, a second starting contact, and a transmission contact located ona midperpendicular of the first starting contact and the second starting contact are vertically arranged are arranged on the end surface of the transmitter, a receiver corresponding to the transmitteris arranged on the base, a first guiding groove and a second guiding groove are vertically arranged on the end face of the receiver, a starting point receiving contact is arranged in the first guiding groove, a receiving contact is arranged in the second guiding groove, a high-speed coding and transmitting circuit is arranged in the transmitter, data collected by a sensor group on the roller arecoded and transmitted through the high-speed coding and transmitting circuit, and a data processing circuit used for data decoding is arranged in the receiver. According to the system, the mode of non-fixed mechanical point contact is adopted, the temperature and humidity of multiple parts in the roller can be measured and instantly transmitted, so that the whole drying process can be optimized conveniently.
